When the first rotating shaft 311 is used as the central axis, there is a third distance between the first rotating shaft 311 and the outer side surface 13 of the case 10, and when the second rotating shaft 321 is used as the central axis, the second rotating shaft 321 and the case There is a fourth distance between the outer sides 13 of the 10, and the fourth distance is smaller than the third distance.

The specific instructions are as follows:

In certain motion trajectories of the refrigerator 100 , the first rotating shaft 311 and the second rotating shaft 321 will move relative to the door body 20 , or the hinge assembly 30 further includes other shafts matching the first rotating shaft 311 and the second rotating shaft 321 , In order to simplify the description, it is simply considered that the door body 20 first rotates with the first rotation shaft 311 as the axis, and then is switched to rotate with the second rotation axis 321 as the axis through the switching component 40 .

In actual operation, in order to improve the embedding effect, it is preferable to completely embed the refrigerator 100 into the cabinet 200 , and the refrigerator 100 is a free embedded refrigerator, that is, the front end 201 of the cabinet 200 and the front wall 21 of the door 20 away from the cabinet 10 . On the same plane, or the front wall 21 of the door body 20 does not protrude from the front end 201 of the cabinet 200 at all.

In the prior art, refrigerators are all single-axis refrigerators, and a certain distance needs to be maintained between the rotating shaft of the refrigerator and the side wall and front wall of the refrigerator, so that there is enough space for foaming or other processes, that is, the existing The position of the rotation axis of the refrigerator is approximately at the position of the first rotation axis 311 in FIG. 4 . In this case, after the single-axis refrigerator is embedded into the cabinet 200 , since the cabinet 200 is sandwiched by the edge between the front end 201 and the inner wall 202 203 is set corresponding to the side edge 23 of the door body 20. When the door body 20 is opened, the side edge 23 will interfere with the door body 20 to limit the maximum opening angle of the door body 20. In order to ensure the normal opening of the door body 20, the prior art The common practice is to increase the distance between the inner wall 202 of the cabinet 200 and the refrigerator 100 , which generally needs to be about 10 cm, which will seriously affect the embedding effect and is not conducive to the rational use of limited space.

With reference to FIG. 4 , the shaded area represents the door body 20 in the closed state. When the door body 20 is in the opening process, if the door body 20 always rotates around the first rotation axis 311 (ie, the prior art), refer to FIG. 4 . The dotted door body 20' shown in the figure, because the first rotating shaft 311 is close to the front end surface 103, that is, the first shaft body 311 is far away from the front end 201 of the cabinet 200, when the door body 20' is opened to a certain angle, the corners 203 of the cabinet 200 will Interfering with the door body 20' to limit the maximum opening angle of the door body 20'.

In this embodiment, the second rotating shaft 321 is located on the switch assembly 40. During the opening process of the door body 20, the switch assembly 40 moves relative to the first hinge member 31 and the second hinge member 32 so that the second rotating shaft 321 gradually moves Away from the front end surface 103 , that is, the second rotating shaft 321 gradually moves toward the direction close to the front end 201 of the cabinet 200 , that is, at this time, the entire door body 20 moves in a direction away from the box body 10 , refer to the solid line door body in FIG. 4 . 20. The interference effect of the edges and corners 203 of the cabinet 200 on the door body 20 is greatly reduced. When the door body 20 is opened to a larger angle, the edges and corners 203 of the cabinet 200 interfere with each other, thereby greatly increasing the maximum opening angle of the door body 20 .

That is to say, in this embodiment, through the function of the switching component 40, the door body 20 can be rotated around the second rotating shaft 321 in the later stage, and on the premise that the refrigerator 100 can be freely embedded in the cabinet 200, the maximum opening of the door body 20 can be effectively improved angle, which facilitates the user to operate the refrigerator 100, which can greatly improve the user experience.

Moreover, in this embodiment, there is no need to increase the distance between the inner wall 202 of the cabinet 200 and the refrigerator 100, and the refrigerator 100 and the cabinet 200 can be seamlessly connected, which greatly improves the embedding effect.

In addition, the switching assembly 40 of the present embodiment drives the second rotating shaft 321 to gradually move toward the direction close to the front end 201 of the cabinet 200, and also drives the second rotating shaft 321 to gradually approach the inner wall 202 of the cabinet 200, that is, when When the door body 20 rotates around the second rotating shaft 321, the second rotating shaft 321 is closer to the front end 201 and the inner wall 202 of the cabinet 200 than the first rotating shaft 311 at this time, so that the door body 20 can be improved. The maximum opening angle can make the door 20 away from the box 10 to increase the opening of the box 10, which facilitates the opening and closing of the shelves, drawers, etc. in the box 10, or facilitates the taking and placing of items.

Of course, the second rotating shaft 321 that finally serves as the rotating shaft can also be located at other positions. For example, when the door body 20 rotates around the second rotating shaft 321, the second rotating shaft 321 at this moment The shaft 311 is close to the front end 201 of the cabinet 200 , and the second rotating shaft 321 is farther from the inner wall 202 of the cabinet 200 than the first rotating shaft 311 , and so on.

It can be understood that the switching assembly 40 controls the switching sequence of the first hinge member 31 and the second hinge member 32 during the opening and closing of the door body 20, which can effectively prevent the door body 20 from interfering with the cabinet 200 during the opening and closing process.

For the specific design of the hinge assembly 30 in this embodiment, reference may be made to the following examples. It should be understood that the following are only schematic examples, and in other embodiments, the hinge assembly 30 may also have other structures.

When the first opening angle α1 continues to open to the second opening angle α2, the first sliding blade group 401 moves relative to the second sliding blade group 402 to lock the first hinge member 31 and unlock the second hinge member 32. When the assembly 30 is in the process of continuing to open from the second opening angle α2 to the maximum opening angle α3, the first hinge member 31, the first sliding blade group 401 and the second sliding blade group 402 are relatively static, and the second hinge member 32 is relatively switched. The assembly 40 moves, and the first direction is the stacking direction of the first hinge member 31 , the switch assembly 40 and the second hinge member 32 .

It can be understood that when the hinge assembly 30 is installed on the refrigerator 100 , the opening angle of the hinge assembly 30 corresponds to the opening angle of the door body 20 .

Specifically, the first hinge member 31 and the switch assembly 40 are connected by the first shaft body groups 311, 312 and the first groove body groups 411, 412 that cooperate with each other, and the second hinge member 32 and the switch assembly 40 are connected by mutual The matched second shaft body groups 321 and 322 and the second groove body groups 421 and 422 are connected.

The first shaft body groups 311 and 312 include a first shaft body 311 and a second shaft body 312 , and the first groove body groups 411 and 412 include a first groove body 411 matched with the first shaft body 311 and a second shaft body 312 . The matched second groove body 412 , the second shaft body group 321 , 322 includes the third shaft body 321 and the fourth shaft body 322 , and the second groove body group 421 , 422 includes the third groove body matched with the third shaft body 321 421 and the fourth groove body 422 matched with the fourth shaft body 322 .

Here, the first shaft body 311 is located at one of the first hinge member 31 and the switch assembly 40 , and the first groove body 411 is located at the other of the first hinge member 31 and the switch assembly 40 .

The second shaft body 312 is located at one of the first hinge member 31 and the switch assembly 40 , and the second groove body 412 is located at the other of the first hinge member 31 and the switch assembly 40 .

The third shaft body 321 is located at one of the second hinge member 32 and the switch assembly 40 , and the third groove body 421 is located at the other of the second hinge member 32 and the switch assembly 40 .

The fourth shaft body 322 is located at one of the second hinge member 32 and the switch assembly 40 , and the fourth groove body 422 is located at the other of the second hinge member 32 and the switch assembly 40 .

That is to say, the distribution form of the hinge assembly 30 can include a variety of situations, and the specific situation can be determined according to the actual situation. 32 includes a third groove body 421 and a fourth groove body 422 , and the switch assembly 40 includes a first groove body 411 , a second groove body 412 , a third shaft body 321 and a fourth shaft body 322 as an example.

It can be seen that in this embodiment, the first hinge member 31 and the switch assembly 40 are in the form of two-axis and two-slot cooperation, and the second hinge member 32 and the switch assembly 40 are in the form of two-axis and two-groove cooperation. This is the limit.

In other embodiments, a single-shaft single-slot matching form may also be included. For example, the first shaft body group includes a first shaft body, the first groove body group includes a first groove body matching with the first shaft body, and /or the second shaft body group includes a third shaft body, and the second groove body group includes a third groove body matched with the third shaft body.

Of course, the first hinge member 31 and the switch assembly 40 may also be in the form of a single shaft and a single slot, and the second hinge member 32 and the switch assembly 40 may be in the form of two shafts and two grooves, or the first The hinge member 31 and the switch assembly 40 are in the form of two-axis and two-slot cooperation, and the second hinge member 32 and the switch assembly 40 are in the form of single-axis and single-slot cooperation. Of course, other numbers of shafts and slots are also possible. body fit.

In this embodiment, referring to FIGS. 5 and 6 , the first groove body 411 includes a first upper groove body 413 located in the first sliding vane group 401 and a first lower groove body 414 located in the second sliding vane group 402 . The first upper groove body 413 includes a first upper free section 4131 , and the first lower groove body 414 includes a first lower free section 4141 .

The second groove body 412 includes a second upper groove body 415 located in the first sliding vane group 401 and a second lower groove body 416 located in the second sliding vane group 402. The second upper groove body 415 includes a second upper free section 4151. The second lower tank body 416 includes a second lower free section 4161 .

The third groove body 421 includes a third free segment 4211 .

The fourth groove body 422 includes a fourth free segment 4221 .

The first groove body groups 411 and 412 include locking segments 4132 , 4142 , 4152 and 4162 , and the second groove body groups 421 and 422 include limiting segments 4222 .

The locking segments 4132 , 4142 , 4152 and 4162 include a first upper locking segment 4132 located on the first upper groove body 413 , a first lower locking segment 4142 located on the first lower groove body 414 , and a first lower locking segment 4142 located on the second upper groove body 415 . The second upper locking segment 4152 and the second lower locking segment 4162 located in the second lower groove body 416 , the limiting segment 4222 includes a fourth limiting segment 4222 located in the fourth groove body 422 .

The first upper locking section 4132 communicates with the first upper free section 4131, the first lower locking section 4142 communicates with the second lower free section 4141, the second upper locking section 4152 communicates with the second upper free section 4151, and the second lower locking section The segment 4162 communicates with the second lower free segment 4161 .

The first upper locking segment 4132 and the first lower locking segment 4142 are always staggered from each other, and the second upper locking segment 4152 and the second lower locking segment 4162 are always staggered from each other.

Here, "always staggered from each other" means that during the opening process of the door body 20, the first upper locking segment 4132 and the first lower locking segment 4142 will not be completely overlapped, and the second upper locking segment 4152 and the second upper locking segment 4152 will not completely overlap. The lower locking segment 4162 also does not appear to be completely coincident.

Of course, the location and quantity of the locking segments 4132, 4142, 4152, 4162 and the limiting segments 4222 are not limited to the above description. For example, the third groove body 421 may also include the limiting segments 4222, or the first upper The groove body 413 and the first lower groove body 414 do not include locking segments and the like.

In this embodiment, the first sliding vane set 401 is closer to the first hinge member 31 than the second sliding vane set 402 , that is, the first hinge member 31 , the first sliding vane set 401 , the second sliding vane set 402 and the The two hinge members 32 are stacked in sequence.

5 and 6, the hinge assembly 30 further includes a first riveting piece 4111 and a second riveting piece 4121. When the first shaft body 311 extends into the first groove body 411, the first riveting piece 4111 is located on the second sliding piece The bottom of the group 402 is sleeved with the first shaft body 311, so that the first shaft body 311 can be prevented from being separated from the first groove body 411. Similarly, when the second shaft body 312 extends into the second groove body 412, the second riveting The sheet 4121 is located below the second sliding sheet set 402 and is sleeved with the second shaft body 312 , so that the second shaft body 312 can be prevented from being separated from the second groove body 412 .

The first sliding vane group 401 and the second sliding vane group 402 are connected to each other through the fifth shaft body 50 .

Here, the first sliding vane set 401 and the second sliding vane set 402 are provided with a first through hole 4014 and a second through hole 4024, and an independent riveting member as the fifth shaft body 50 passes through the first through hole 4014 and the second through hole 4024 Through hole 4024.

Specifically, the fifth shaft body 50 includes a riveting column 51 and a riveting column washer. The larger end of the riveting column 51 is located below the second through hole 4024 , and the smaller end of the riveting column 51 extends to the second In the through hole 4024 and the first through hole 4014, the riveting column spacer is located above the first through hole 4014 and cooperates with the riveting column 51 to lock the riveting column 51. Of course, other matching forms are also possible.

In this way, the mutual mating of the first sliding vane group 401 and the second sliding vane group 402 can be realized, and the relative movement of the first sliding vane group 401 and the second sliding vane group 402 can be realized, and the first sliding vane group 401 and the The second vane groups 402 are not separated from each other.

It should be noted that, the first through hole 4014 and the second through hole 4024 are matched with the fifth shaft body 50 , and the first sliding vane group 401 rotates in place relative to the second sliding vane group 402 .

In other embodiments, a through hole may be provided on one of the first sliding vane set 401 and the second sliding vane set 402 , and a fifth shaft body 50 may be set on the other one, through the fifth shaft body 50 and the through hole The matching of the first sliding vane group 401 and the second sliding vane group 402 can realize the mutual matching, but it is not limited to this.

In addition, the first sliding vane set 401 includes a third shaft body 321, the third shaft body 321 extends beyond the second sliding vane set 402 to the third groove body 421, the second sliding vane set 402 includes a fourth shaft body 322, The four-axis body 322 extends to the fourth groove body 422 .

That is to say, the third shaft body 321 and the fourth shaft body 322 in this embodiment are located in different sliding vane groups, but not limited thereto.

Next, the specific work flow of the hinge assembly 30 is introduced.

7 to 22, when the hinge assembly 30 is in the process of opening from the closed state to the first opening angle α1, the first sliding vane group 401 and the second sliding vane group 402 are relatively stationary, and the first upper free section 4131 and the The first lower free segment 4141 overlaps to form the first free segment S1, the second upper free segment 4151 overlaps with the second lower free segment 4161 to form the second free segment S2, the first shaft 311 moves in the first free segment S1, the second The shaft body 312 moves in the second free section S2 , and the third shaft body 321 and/or the fourth shaft body 322 is limited to the limiting section 4222 so that the switch assembly 40 limits the second hinge member 32 .

Here, "the third shaft body 321 and/or the fourth shaft body 322 is limited to the limiting section 4222" means that the third shaft body 321 is limited to the limiting section 4222 (that is, the limiting section 4222 is located in the third groove body 421) The fourth shaft body 322 is not limited, or the third shaft body 321 is not limited and the fourth shaft body 322 is limited to the limiting section 4222 (that is, the limiting section 4222 is located in the fourth groove body 422), or Both the triaxial body 321 and the fourth shaft body 322 are limited to the limiting section 4222 (that is, the limiting section 4222 is located in the third groove body 421 and the fourth groove body 422 at the same time).

Specifically, the fourth shaft body 322 is limited to the fourth limiting section 4222, and the second hinge member 32 is in a locked state.

Here, since the first upper free segment 4131 and the first lower free segment 4141 always overlap into the first free segment S1, the second upper free segment 4151 and the second lower free segment 4161 always overlap into the second free segment S2, that is, the first free segment S2. The movement trajectories of the sliding vane group 401 and the second sliding vane group 402 are exactly the same, and the first shaft body 311 moves in the first free section S1, and at the same time, the second shaft body 312 moves in the second free section S2. During this process The first sliding vane set 401 and the second sliding vane set 402 will never be staggered from each other, that is, the first sliding vane set 401 and the second sliding vane set 402 remain relatively static, which can avoid the first upper free section 4131 and the first lower free section 4131. The sections 4141 are displaced from each other, and at the same time, the second upper free section 4151 and the second lower free section 4161 are prevented from being displaced from each other. In this way, the first shaft 311 can be smoothly moved in the first free section S1, and the second shaft 312 can be smoothly moved in the second free section S1. The free segment S2 moves smoothly.

23 to 26 , when the hinge assembly 30 continues to open from the first opening angle α1 to the second opening angle α2, the first sliding vane group 401 and the second sliding vane group 402 move relatively so that the second The hinge member 32 is released from the limit of the switch assembly 40 , and the first shaft body 311 and/or the second shaft body 312 are limited to the locking sections 4132 , 4142 , 4152 , 4162 so that the switch assembly 40 limits the first hinge member 31 .

Here, “the relative movement of the first sliding vane set 401 and the second sliding vane set 402 makes the second hinge member 32 disengage from the limit of the switching assembly 40, and the first shaft body 311 and/or the second shaft body 312 are limited to the lock Stopping the sections 4132, 4142, 4152, 4162 to make the switch assembly 40 limit the first hinge member 31 ″ refers to the relative movement between the switch assembly 40 and the second hinge member 32 so that the switch assembly 40 and the second hinge member 32 are moved relative to each other. There is no mutual limit, and the relative movement between the switch assembly 40 and the first hinge member 31 causes the switch assembly 40 and the first hinge member 31 to limit each other.

In an example, the first shaft body 311 is simultaneously limited to the first upper locking segment 4132 and the first lower locking segment 4142, and the second shaft body 312 is simultaneously limited to the second upper locking segment 4152 and the second lower locking segment segment 4162, and the fourth shaft body 322 is separated from the fourth limiting segment 4222, the description is as follows:

When the door body 20 is opened to the first opening angle α1, the second shaft body 312 moves from the second free section S2 to the second lower locking section 4162 and is limited. At this time, the first shaft body 311 and the second shaft body 312 The first free section S1 and the second free section S2 can no longer be moved, and the first shaft 311 is adjacent to the first upper locking section 4132 and the first lower locking section 4142, and the second shaft 312 is adjacent to the second The trajectory of the upper locking segment 4152 , the first upper locking segment 4132 and the second upper locking segment 4152 is adapted to the movement path of the first shaft body 311 and the second shaft body 312 .

When the door body 20 continues to open on the basis of the first opening angle α1, the door body 20 drives the second hinge member 32 connected to the door body 20 to move, and the second hinge member 32 passes through the third free section 4211 and the fourth limit section 4222 to exert a force on the third shaft body 321 and the fourth shaft body 322, and then the third shaft body 321 and the fourth shaft body 322 drive the first sliding vane set 401 and the second sliding vane set 402 to move.

Specifically, at this time, the first shaft body 311 is adjacent to the first upper locking section 4132, the second shaft body 312 is adjacent to the second upper locking section 4152, and the first sliding vane group 401 can be opposite to the first shaft body 311 and the second shaft The body 312 moves the first angle until the first shaft body 311 is limited to the first upper locking section 4132, and the second shaft body 312 is limited to the second upper locking section 4152. The shaft body 50 is the center of the circle and moves a second angle relative to the first shaft body 311 until the first shaft body 311 is confined within the second locking section 4152 . During this process, the second shaft body 312 and the second lower locking section 4162 always touch, the second angle is greater than the first angle.

That is to say, both the first sliding vane group 401 and the second sliding vane group 402 will rotate at a certain angle, and the rotation angle of the second sliding vane group 402 is greater than the rotation angle of the first sliding vane group 401, and the first sliding vane group 401 A relative movement is also generated with the second sliding vane group 402 so as to be offset from each other.

It can be understood that the rotation process of the first sliding vane group 401 and the second sliding vane group 402 does not have a certain sequence, and the two may rotate at the same time. For example, the first sliding vane group 401 and the second sliding vane group 402 rotates synchronously within a certain rotation angle range, and then the first sliding vane group 401 and the second sliding vane group 402 are staggered from each other.

In actual operation, the first sliding vane set 401 and the second sliding vane set 402 drive the first groove body 411 and the second groove body 412 to rotate relative to the first shaft body 311 and the second shaft body 312 respectively, and the first shaft body 311 is disengaged The first free segment S1 is in contact with the first upper locking segment 4132 and the first lower locking segment 4142, that is, the first shaft body 311 is limited to the first upper locking segment 4132 and the first lower locking segment 4142 at the same time, The second shaft body 312 is separated from the second free section S2 and abuts against the second upper locking section 4152 and the second lower locking section 4162 , that is, the second shaft body 312 is limited to the second upper locking section 4152 and the second locking section 4162 at the same time. The lower locking section 4162 and at the same time, the movement of the second sliding vane group 402 makes the fourth shaft 322 disengage from the fourth limiting section 4222 .

It can be understood that when the first shaft body 311 is located at the first upper locking section 4132 and the first lower locking section 4142, since the first sliding vane set 401 and the second sliding vane set 402 are staggered from each other, originally The overlapping first upper free section 4131 and the first lower free section 4141 are also staggered from each other. At this time, the mutually staggered first upper free section 4131 and the first lower free section 4141 restrict the first shaft body 311 from disengaging from the first upper lock The segment 4132 and the first lower locking segment 4142 can ensure that the first shaft body 311 is always kept at the first upper locking segment 4132 and the first lower locking segment 4142 during the process of the door body 20 being continuously opened.

Similarly, when the second shaft body 312 is located at the second upper locking section 4152 and the second lower locking section 4162, since the first sliding vane set 401 and the second sliding vane set 402 are staggered from each other, they originally overlapped with each other. The second upper free section 4151 and the second lower free section 4161 are also staggered from each other. At this time, the staggered second upper free section 4151 and the second lower free section 4161 limit the second shaft body 312 from the second upper locking section. 4152 and the second lower locking section 4162 can ensure that the second shaft body 312 is always kept at the second upper locking section 4152 and the second lower locking section 4162 during the process of the door body 20 continuing to open.

In addition, the rotation angle of the second sliding vane set 402 is greater than the rotation angle of the first sliding vane set 401 , that is, the second sliding vane set 402 and the first sliding vane set 401 are staggered from each other, which can further improve the relationship between the first hinge member 31 and the first sliding vane set 401 . The locking effect between the switching components 40 ensures that the first shaft body 311 is always kept at the first upper locking section 4132 and the first lower locking section 4142, and the second shaft body 312 is always kept at the second upper locking section segment 4152 and the second lower locking segment 4162.

27 to 30, when the hinge assembly 30 continues to open from the second opening angle α2 to the maximum opening angle α3, the third shaft 321 moves in the third free section 4211, and the fourth shaft 322 moves in the fourth Free segment 4221 moves.

It can be seen that in this embodiment, through the unlocking and locking functions of the switching component 40 on the first hinge member 31 and the second hinge member 32, the sequence switching of the first hinge member 31 and the second hinge member 32 can be effectively controlled, so that the door The body 20 can be stably opened.

It can be understood that when the door body 20 is in the closing process, that is, when the door body 20 starts to close from the maximum opening angle α3, the switching component 40 can also effectively control the sequence switching of the first hinge member 31 and the second hinge member 32, that is, When the door body 20 is in the process of closing from the maximum opening angle α3 to the second opening angle α2, the third shaft body 321 moves in the third free section 4211, the fourth shaft body 322 moves in the fourth free section 4221, and switches The assembly 40 locks the first hinge member 31. When the door body 20 is in the process of closing from the second opening angle α2 to the first opening angle α1, the first sliding vane group 401 and the second sliding vane group 402 move relatively so that the The first hinge member 31 is separated from the limit of the switch assembly 40, and the fourth shaft 322 is limited to the fourth limit section 4222. The switch assembly 40 locks the second hinge member 32. When the door body 20 is at the first opening angle α1 During the process of closing to complete closing, the first shaft body 311 moves in the first free section S1, and the second shaft body 312 moves in the second free section S2.

In other words, the closing process of the door body 20 and the opening process of the door body 20 are processes in reverse order, and the door can be effectively controlled by the unlocking and locking functions of the switch assembly 40 on the first hinge member 31 and the second hinge member 32 The switching sequence of the first hinge member 31 and the second hinge member 32 during the opening and closing process of the body 20 .

In addition, in this embodiment, the first shaft body 311 and the third shaft body 321 are shifted from each other.

When the door body 20 is in the process of opening to the first opening angle α1 from the closed state, the door body 20 rotates with the first shaft body 311 as the central axis. When the door body 20 continues to open from the second opening angle α2 to the maximum opening angle During the process of α3, the door body 20 rotates with the third shaft body 321 as the axis.

When the first shaft body 311 is used as the central axis, there is a first distance between the first shaft body 311 and the front end surface 103 of the box body 10 , and a third distance between the first shaft body 311 and the outer surface 13 of the box body 10 , when the third shaft body 321 is used as the central axis, there is a second distance between the third shaft body 321 and the front end surface 103 of the box body 10 , and a fourth distance between the third shaft body 321 and the outer surface 13 of the box body 10 distance, the second distance is greater than the first distance, and the fourth distance is less than the third distance.

Referring to the foregoing description, the hinge assembly 30 of this embodiment may be applicable to a built-in cabinet or a scenario where the space for accommodating the refrigerator 100 is small.

In addition, it should be noted that the movement trajectory of the door body 20 can be effectively controlled by the specific shaft body groove design. In this embodiment, the box body 10 includes the pivot side P connecting the hinge assembly 30. When the door body 20 is in the During the opening process, the hinge assembly 30 at least drives the door body 20 to move from the pivot side P toward the accommodating chamber D, so as to prevent the door body 20 from interfering with the surrounding cabinets or walls during the opening process. The specific design can refer to the following example.

In an example, the first free section S1 includes an initial position A1 and a stop position A2 that are oppositely arranged, and the second free section S2 includes a first section L1, a second section L2 and a third section L3 that are connected in sequence.

7 to 10 , when the door body 20 is in the closed state, the first shaft body 311 is at the initial position A1, the second shaft body 312 is at the end of the first section L1 away from the second section L2, and the fourth shaft body 322 The switch assembly 40 is positioned at the limiting section 4222 to limit the second hinge member 32 .

11 to 22 , when the door body 20 is in the process of opening from the closed state to the first opening angle α1, the first shaft body 311 rotates in place at the initial position A1, and the second shaft body 312 rotates with the first shaft body 311 is the center of the circle and moves in the first section L1, the door body 20 rotates in place relative to the box body 10, and then the second shaft body 312 moves in the second section L2 to drive the first shaft body 311 to move from the initial position A1 to stop At position A2, the door body 20 moves from the pivot side P toward the accommodating chamber D, and then the second shaft body 312 moves in the third section L3 to drive the first shaft body 311 to move from the stop position A2 to the initial position A1, and the door body 20 is moved by the accommodation chamber D towards the pivot side P.

Specifically, referring to FIGS. 11 to 14 , when the door body 20 is in the process of being opened from the closed state to the first intermediate opening angle α11, the first shaft body 311 rotates in place at the initial position A1, and the second shaft body 312 rotates at the initial position A1. The first shaft body 311 is the center of the circle and moves within the first segment L1, and the door body 20 rotates relative to the box body 10 in place.

The rotation causes a displacement relative to the box body 10 along the first direction X. In this way, the distance that the door body 20 protrudes from the box body 10 toward the side away from the accommodating chamber D during the rotation process will be greatly reduced, that is, the door body will be greatly reduced. The displacement of 20 along the first direction X offsets the part of the door body 20 protruding out of the box body 10 along the second direction Y during the rotation process of the door body 20, thereby preventing the door body 20 from interfering with the surrounding cabinets or walls during the opening process. , suitable for built-in cabinets or scenarios where the space for accommodating the refrigerator 100 is small.

Here, the first direction X is the direction in which the pivot side P faces the accommodating chamber D, and the second direction Y is the direction in which the accommodating chamber D faces the pivot side P.

19 to 22, when the door body 20 is in the process of opening from the second intermediate opening angle α12 to the first opening angle α1, the second shaft body 312 moves in the third section L3 to drive the first shaft body 311 Moving from the stop position A2 to the initial position A1, the door body 20 moves from the accommodating chamber D to the pivot side P.

Here, when the door body 20 is in the process of opening from the second intermediate opening angle to the first opening angle α1, the door body 20 moves toward the side of the pivot side P, that is, at this time, the door body 20 is both relative to the box body 10. The rotation also produces a displacement relative to the box body 10 along the second direction Y. In this way, the door body 20 can be kept away from the box body 10 as far as possible, so as to ensure the opening of the box body 10 and prevent the drawers and shelves in the box body 10 from being affected by the door. The problem that the body 20 interferes and cannot be opened.

23 to 26, when the door body 20 is in the process of continuing to open from the first opening angle α1 to the second opening angle α2, the fourth shaft body 322 is separated from the limiting section 4222, and the first shaft body 311 and/or Or the second shaft body 312 is limited to the locking segments 4132 , 4142 , 4152 , 4162 so that the switch assembly 40 is limited to the first hinge member 31 .

27 to 30 , when the door body 20 is in the process of continuing to open from the second opening angle α2 to the maximum opening angle α3, the third shaft body 321 rotates in place in the third free section 421, and the fourth shaft body 322 Taking the third shaft body 321 as the center of the circle and moving on the fourth free section 4221, the door body 20 continues to rotate relative to the box body 10 in place.

It should be noted that "the cover plate 80c is connected to the switch assembly 40c" means that the cover plate 80c is directly or indirectly connected to the switch assembly 40c.

Here, the switch assembly 40c is sandwiched between the first hinge member 31c and the second hinge member 32c. When the second hinge member 32c and the switch member 40c move relative to each other, the switch member 40c is close to the side of the second hinge member 32c The cover plate 80c is provided to shield the side of the switch assembly 40c close to the second hinge member 32c, so as to prevent external dust or impurities from entering the switch assembly 40c, and the overall aesthetics can be improved.

In this embodiment, the switch assembly 40c includes a first slider group 401c and a second slider group 402c stacked along the first direction, and the cover plate 80c is located at a position of the second slider group 402c away from the first slider group 401c On the side, the cover plate 80c is fixed on the first sliding vane set 401c or the second sliding vane set 402c.

Specifically, in the direction of the first hinge member 31c toward the second hinge member 32c, the switch assembly 40c sequentially includes a first lining sheet 4011c, a first sliding sheet 4012c, an intermediate lining sheet 4013c, a second sliding sheet 4021c and a second lining sheet Sheet 4022c, the cover plate 80c is fixed to one of the first lining sheet 4011c, the first sliding sheet 4012c, the intermediate lining sheet 4013c, the second sliding sheet 4021c and the second lining sheet 4022c.

The first lining sheet 4011c, the first sliding sheet 4012c and the intermediate lining sheet 4013c are stacked in sequence to form the first sliding sheet group 401c, and the second sliding sheet 4021c and the second lining sheet 4022c are stacked to form the second sliding sheet group 402c, but not limited to this.

Generally, the first lining sheet 4011c, the intermediate lining sheet 4013c, and the second lining sheet 4022c are made of plastic materials, such as POM (polyformaldehyde, polyoxymethylene).

The first sliding vane 4012c and the second sliding vane 4021c are made of metal, such as stainless steel or Q235 steel.

In this embodiment, the switch assembly 40c and the second hinge member 32c cooperate with the groove bodies 421c and 422c through the shaft bodies 321c and 322c, and the cover plate 80c has through holes 84c and 85c for the shaft bodies to pass through.

Specifically, for example, when the first sliding vane set 401c includes the third shaft body 321c, the second sliding vane set 402c includes the fourth shaft body 322c, and the second hinge member 32c correspondingly includes the third groove body 421c and the fourth groove body 422c The cover plate 80c has a first through hole 84c through which the third shaft body 321c passes and a second through hole 85c through which the fourth shaft body 322c passes.

Referring to FIG. 45 , when the second hinge member 32c and the second sliding vane group 402c are relatively stationary, part of the inner contour of the second through hole 85c is consistent with the inner contour of the fourth limiting section 4222c of the fourth groove body 422c.

At this time, when the second hinge member 32c is in the locked state, the fourth shaft body 322c is simultaneously limited to the fourth limiting section 4222c and the second through hole 85c, that is, the second through hole 85c can assist in locking the fourth shaft body 322c.

The inner contour of the second through hole 85c is provided with a convex point 851c for restricting the movement of the fourth shaft body 322c, and the convex point 851c can further improve the limiting effect on the fourth shaft body 322c.

The hinge member 31c, that is, the gravity will not be transmitted to the second sliding vane group 402c at this time, and the second sliding vane group 402c can move smoothly relative to the first sliding vane group 401c in the cavity S.

That is to say, at this time, the cover plate 80c not only plays the role of shielding, but also plays the role of gravity transmission, and the contact area between the cover plate 80c and the second hinge member 32c is larger, and the cover plate 80c can be more stable and efficient. By transmitting the gravity to the first sliding vane group 401c, the wear of the hinge assembly 30c can be minimized and the work of the hinge assembly 30c can be made smoother.

It should be noted that the cover plate 80c can be connected to the first slider 4012c in the first slider group 401c. Since the first slider 4012c is made of metal, it can stably support the cover plate 80c. Of course, the cover plate 80c can also be connected First lining 4011c or intermediate lining 4013c.

When the cover plate 80c contacts the second slider group 402c, the cover plate 80c is fixed to the first slider group 401c or the second slider group 402c. At this time, the cover plate 80c plays a shielding role.

At this time, when the gravity of the door body 20 acts on the second hinge member 32c, the second hinge member 32c transmits the gravity to the cover plate 80c, and the cover plate 80c transmits the gravity to the second sliding plate group 402c and the first sliding plate group 402c in turn. The hinge member 31c, that is, the gravity will not be transmitted to the first sliding vane group 401c at this time, and the first sliding vane group 401c can move smoothly relative to the second sliding vane group 402c in the cavity S.

That is to say, at this time, the cover plate 80c not only plays the role of shielding, but also plays the role of gravity transmission, and the contact area between the cover plate 80c and the second hinge member 32c is larger, and the cover plate 80c can be more stable and efficient. By transmitting the gravity to the second sliding vane group 402c, the wear of the hinge assembly 30c can be minimized and the operation of the hinge assembly 30c can be made smoother.

It should be noted that, at this time, the cover plate 80c may not be provided, and the second hinge member 32c directly contacts the second sliding vane assembly 402c.

For other descriptions of the hinge assembly 30 c and the refrigerator 100 in the third embodiment, reference may be made to the foregoing embodiment and the following embodiment, and details are not repeated here.

48 to 51, it is a schematic diagram of the hinge assembly 30d of the fourth embodiment.

In the fourth embodiment, the hinge assembly 30d includes a first hinge member 31d provided on the box body 10, a second hinge member 32d provided on the door body 20, and a switch assembly connecting the first hinge member 31d and the second hinge member 32d 40d, the switching assembly 40d includes a first sliding plate group 401d and a second sliding plate group 402d that are stacked and movably connected in the first direction, and the switching assembly 40d also includes a frame body portion 43d that surrounds and forms a cavity S. The frame body portion 43d is connected to the first sliding vane group 401d, and the second sliding vane group 402d is movably arranged in the cavity S.

Here, the second slider group 402d is located in the cavity S formed by connecting the frame portion 43d of the first slider group 401d, and the second slider group 402d moves relative to the first slider group 401d in the cavity S. In this way, The overall compactness of the switching assembly 40d can be greatly improved.

In this embodiment, in the direction of the first hinge member 31d toward the second hinge member 32d, the switch assembly 40d sequentially includes a first lining sheet 4011d, a first sliding sheet 4012d, an intermediate lining sheet 4013d, a second sliding sheet 4021d and The second lining 4022d.

The first lining sheet 4011d and the first sliding sheet 4012d are stacked to form the first sliding sheet group 401d, and the intermediate lining sheet 4013d, the second sliding sheet 4021d and the second sliding sheet 4022d are stacked in sequence to form the second sliding sheet group 402d, the middle lining sheet 4013d and the second lining sheet 4022d are connected to each other to form a cavity for accommodating the second sliding sheet 4021d, but not limited thereto.

The frame portion 43d is integrally formed with the first sliding sheet group 401d. Here, the frame portion 43d may be integrally formed with the first lining sheet 4011d, the first sliding sheet 4012d or the intermediate lining sheet 4013d.

Generally, the first lining sheet 4011d, the intermediate lining sheet 4013d, and the second lining sheet 4022d are made of plastic materials, such as POM (polyformaldehyde, polyoxymethylene).

The first sliding vane 4012d and the second sliding vane 4021d are made of metal, such as stainless steel or Q235 steel.

Here, the plastic material is used to wrap the metal sliding vane, so as to prevent the first sliding vane 4012d and the second sliding vane 4021d from directly contacting and rubbing and interfering with each other, and the first sliding vane 4012d directly contacts the middle of the second sliding vane group 402d The lining sheet 4013d can simplify the structure of the first sliding sheet group 401d, thereby reducing the overall thickness of the switching assembly 40d.

In this embodiment, the inner contour of the frame body portion 43d and the outer contour of the second slider group 402d match each other, and there is a gap P between the inner contour of the frame body portion 43d and the outer contour of the second slider group 402d. The second sliding vane group 402d moves relative to the first sliding vane group 401d within the interval P.

Here, "matching each other" means that the inner contour of the frame portion 43d is substantially the same as the outer contour of the second vane group 402d, and the inner contour size of the frame portion 43d is larger than the outer contour size of the second vane group 402d, In this way, the interval P can be formed between the inner contour of the frame body portion 43d and the outer contour of the second vane group 402d.

The inner contour of the frame body portion 43d includes multiple curved surfaces, and the multiple curved surfaces have different circle centers.

That is to say, the inner contour of the frame portion 43d is formed by splicing irregular curved surfaces. At this time, the inner surface of the frame portion 43d close to the cavity S and the outer surface away from the cavity S are solid and have a certain The width, on the one hand, can improve the overall strength of the frame portion 43d, and on the other hand, it can also ensure that there is a sufficient space P for giving way for the second sliding vane group 402d to move relative to the first sliding vane group 401d.

In this embodiment, the cavity S has a first depth along the first direction, the second sliding vane group 402d has a first thickness along the first direction, and the first depth is greater than the first thickness.

That is to say, the second sliding vane group 402d is embedded in the cavity S, and the second sliding vane group 402d does not protrude out of the cavity S in the first direction.

The hinge assembly 30d further includes a cover plate 80d on the side of the switch assembly 40d close to the second hinge member 32d, and the cover plate 80d and the frame portion 43d are fixed to each other.

The cover plate 80d is fixed to the frame portion 43d by screws 82d, and since the second slider group 402d is embedded in the cavity S, there is a gap between the cover plate 80d and the second slider group 402d.

Here, the switch assembly 40d is sandwiched between the first hinge member 31d and the second hinge member 32d. When the second hinge member 32d and the switch member 40d move relative to each other, the switch member 40d is close to the side of the second hinge member 32d The cover plate 80d can block the side of the switch assembly 40d close to the second hinge member 32d, so as to prevent external dust or impurities from entering the switch assembly 40d, and the overall aesthetics can be improved.

It can be understood that, if necessary, a cover plate can also be provided on the side of the switching assembly 40d close to the first hinge member 31d.

In addition, when the gravity of the door body 20 acts on the second hinge member 32d, the second hinge member 32d transmits the gravity to the cover plate 80d, and the cover plate 80d transmits the gravity to the first sliding plate group 401d and the first hinge in turn. 31d, that is, the gravity will not be transmitted to the second sliding vane group 402d at this time, and the second sliding vane group 402d can move smoothly relative to the first sliding vane group 401d in the cavity S.

That is to say, at this time, the cover plate 80d not only plays the role of shielding, but also plays the role of gravity transmission, and the contact area between the cover plate 80d and the second hinge member 32d is larger, and the cover plate 80d can be more stable and efficient. By transmitting the gravity to the first sliding vane group 401d, the wear of the hinge assembly 30d can be minimized and the work of the hinge assembly 30d can be made smoother.

It should be noted that the frame portion 43d can be integrally formed with the first slider 4012d in the first slider group 401d. Since the first slider 4012d is made of metal, the frame portion 43d is also made of metal, and the frame portion 43d is made of metal. The cover plate 80d can be stably supported. Of course, the frame portion 43d can also be connected to the first lining 4011d or the intermediate lining 4013d.

In this embodiment, the first hinge member 31d and the switch assembly 40d are matched with the groove body through the shaft body, the groove body is located on the second sliding plate group 402d, and the side of the groove body close to the frame body portion 43d is the disconnecting portion 431d.

Here, the side of the first lower groove body 414d close to the frame body portion 43d does not have a locking effect, and this part is set as a disconnection portion 431d, which will not affect the guiding and locking effect of the first lower groove body 414d.

In addition, the provision of the disconnecting portion 431d can effectively reduce the volume of the second sliding group 402d, the cavity S can be further reduced, and the frame portion 43d can be further enlarged, thereby improving the overall strength of the switching assembly 40d.

It should be noted that, in other embodiments, referring to FIG. 51 , a frame portion 44d may also be formed on the second slider group 402d, and the frame portion 44d encloses a cavity S for accommodating the first slider group 401d, The cover plate 80d is fixed on the second sliding plate group 402d.

That is to say, the cavity S is located on the side of the second sliding vane set 402d close to the first hinge member 31d, and the second sliding vane set 402d contacts the first hinge member 31d, and the first sliding vane set 401d is located in the cavity S, The cover plate 80d is in contact with the second hinge member 32d and is fixed to each other.

At this time, when the gravity of the door body 20 acts on the second hinge member 32d, the second hinge member 32d transmits the gravity to the cover plate 80d, and the cover plate 80d transmits the gravity to the second sliding plate group 402d and the first sliding plate group 402d in turn. The hinge 31d, that is, the gravity will not be transmitted to the first sliding vane group 401d at this time, and the first sliding vane group 401d can move smoothly relative to the second sliding vane group 402d in the cavity S.

That is to say, at this time, the cover plate 80d not only plays the role of shielding, but also plays the role of gravity transmission, and the contact area between the cover plate 80d and the second hinge member 32d is larger, and the cover plate 80d can be more stable and efficient. By transmitting the gravity to the second sliding vane group 402d, the wear of the hinge assembly 30d can be minimized and the operation of the hinge assembly 30d can be made smoother.

It should be noted that the frame portion 44d can be integrally formed with the second slider 4021d in the second slider group 402d. Since the second slider 4021d is made of metal, the frame portion 44d is also made of metal, and the frame portion 44d is made of metal. The cover plate 80d can be stably supported. Of course, the frame portion 44d can also be connected to the second lining 4022d.

In this embodiment, the switch assembly 40d and the second hinge member 32d cooperate with the groove bodies 421d and 422d through the shaft bodies 321d and 322d, and the cover plate 80d has through holes 84d and 85d for the shaft bodies to pass through.

Specifically, for example, when the first sliding vane set 401d includes the third shaft body 321d, the second sliding vane set 402d includes the fourth shaft body 322d, and the second hinge member 32d correspondingly includes the third groove body 421d and the fourth groove body 422d The cover plate 80d has a first through hole 84d through which the third shaft body 321d passes and a second through hole 85d through which the fourth shaft body 322d passes.

When the second hinge member 32d and the second sliding vane group 402d are relatively stationary, a part of the inner contour of the second through hole 85d is consistent with the inner contour of the fourth limiting section 4222d of the fourth groove body 422d.

At this time, when the second hinge member 32d is in the locked state, the fourth shaft body 322d is simultaneously limited to the fourth limiting section 4222d and the second through hole 85d, that is, the second through hole 85d can assist in locking the fourth shaft Body 322d.

The inner contour of the second through hole 85d is provided with a convex point 851d for restricting the movement of the fourth shaft body 322d, and the convex point 851d can further improve the limiting effect on the fourth shaft body 322d.
