Description

  The present invention relates to a structure of a two-stage push-down switch for a vehicle.

  In a conventional automobile air conditioner, the air volume increases from Lo → M1 → M2 → HI every time a fan switch (hereinafter referred to as SW) is pressed, and after HI, control returns to Lo and repeats this. It has been broken. Also, each time the mode switch is pressed, the air outlet changes from vent to bi-level to heat and the heat outlet that blows to the vicinity of the face. Thereafter, this control is repeated.

  However, in this configuration, since the pattern to be changed is constant, there is a problem that the operation is complicated because it is necessary to operate the SW many times when setting to the previous mode. For example, when the air volume of the blower is set at M1 and it is desired to reduce it to Lo, it is necessary to operate the fan SW three times. During this time, the fan increases in the opposite direction to M2 → HI and gives discomfort. Also, when changing the outlet, it is necessary to operate the mode SW three times to vent the bi-level, and the mode damper moves in the heat direction and then in the vent direction. There is a problem that there is a feeling of discomfort in operation due to a long time until the balloon is blown out or vented (for example, see Patent Document 1).

  On the other hand, Patent Document 1 includes an air volume change direction determining unit that measures the amount of solar radiation and determines whether the air volume is to be increased or decreased according to the amount of solar radiation. A method has been proposed that predicts the change direction of the desired air volume and can reach the air volume desired by the operator with a small number of operations.

  Further, in Patent Document 2, when a slide door of a vehicle is opened and closed, in order to reduce the number of switch operations, when one switch is pressed for a short time, the slide door is unlocked and then the switch is pressed. Measures the amount of time that is required, and when the button is held down, the sliding door is opened before moving to the next operation so that unlocking and opening can be performed with a single operation. A sliding door control device has been proposed. Also in a vehicle air conditioner, when a single switch is pressed for a short time, the set temperature is normally changed one step at a time. Some control air conditioning equipment.

Japanese Patent Laid-Open No. 10-100657 JP 2006-299567 A

  However, as described above, for a switch whose setting state changes depending on whether one switch is long-pressed or short-pressed, the time of short-press and long-press is uniquely determined by the software of the control device. Therefore, it may not suit the preference of individual users, and even if it is just right for a certain user to switch control by long press, it feels redundant to other users, or conversely too short You may feel it. In addition, since the response of the device changes while the same switch is being pressed, it is difficult to understand the operation switching timing when viewed from the user side, and conversely, the operational feeling and operability are reduced. was there.

  Therefore, an object of the present invention is to provide a vehicle switch that reduces the number of times of operation of the operation switch and is excellent in operation feeling and operability.

  The two-stage push-down switch for a vehicle according to the present invention is a two-stage push-down switch for a vehicle in which each contact is sequentially conducted by one push-down portion, and is supported by an elastic body on the base portion and the base portion, and is pushed down by the push-down portion. A first-stage switch that is in a conductive state and moves in a push-down direction, and a second-stage switch that is attached to the base body and pushed down by the first-stage switch that is in a conductive state so that the contact is in a conductive state; When the push-down portion is pushed down, only the first-stage switch is turned on, and when the push-down portion is pushed down, both the first-stage switch and the second-stage switch are turned on.

  In the two-stage push-down switch for a vehicle according to the present invention, the first-stage switch includes a board supported by the elastic body, a first contact attached to the board and pushed down by the push-down portion, and a second contact fixed to the board. And the first contact and the second contact move in the push-down direction in a conductive state, and the second-stage switch is fixed to the base portion and the third contact that is pushed down by the substrate of the first-stage switch in the conductive state And a fourth contact that is electrically connected to the third contact that is pushed down by the substrate.

  In the two-stage push-down switch for a vehicle according to the present invention, the first-stage switch has a push-down portion formed so as to be convex on the surface, and has a first contact of an elastic body provided with a first contact on the side surface opposite to the surface. The sheet and the first conductive sheet are overlapped on the side opposite to the surface of the first conductive sheet via a spacer, provided opposite to the first contact, and provided with a second contact that conducts to the first contact by pressing down the pressing portion on the surface. A second conductive sheet, and the second switch is electrically connected to the second contact and is pushed down by the push-down portion of the first conductive sheet on the surface opposite to the second contact of the second conductive sheet. It is also preferable to include a third contact provided and a third conductive sheet provided with a fourth contact that is overlapped with the second conductive sheet via a spacer and is opposed to the third contact.

  The two-stage push-down switch for a vehicle according to the present invention is a two-stage push-down switch for a vehicle in which each contact is sequentially conducted by one push button, and includes a base portion and first and second contacts provided on the base portion. The third contact point that is supported by the first elastic body attached to the base portion at a distance from the base portion, and the distance from the base portion by the second elastic body attached to the base portion is greater than the third contact point. A fourth contact supported so as to be larger, and a first elastic body and a push button so as to contact the push button, and the first elastic body is elastically deformed by pressing the push button, A third elastic body that pushes down the third contact toward the first contact and is elastically deformed so that a distance between the base portion and the push button is shortened when the third contact is pressed against the first contact; and a push button The second elastic body and the pusher And a projecting piece that elastically deforms the second elastic body by pushing down the push button and pushes the fourth contact toward the second contact, the push button side of the third elastic body The distance in the push-down direction between the end and the third contact is longer than the distance in the push-down direction between the push button side end of the projecting piece and the fourth contact, and when the push button is pushed down, the first elastic body is deformed. When only the three contacts and the first contact come into contact with each other and the push button is pushed down, the fourth contact comes into contact with the second contact due to the deformation of the second and third elastic bodies, and the third contact and the first contact. The contact point, the fourth contact point, and the second contact point are electrically connected to each other.

  The present invention produces an effect that the number of operations of the operation switch can be reduced, and a switch for a vehicle excellent in operational feeling and operability can be provided.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, a two-stage push-down switch 10 for a vehicle that is an embodiment of the present invention includes a housing 11 that is a base portion, and a push button 13 that is a slidably attached to the housing 11. A spring 15 which is an elastic body attached to the housing 11, a first stage switch 20 supported by the spring 15, and a pedestal 14 provided on the bottom plate 11 b side of the housing 11 of the first stage switch 20. And a fixed second stage switch 30.

  The first stage switch 20 includes a substrate 12 supported by the housing 11 via a spring 15, a hinge 23 provided on the substrate 12 and including a spring inside, and an arm 22 that rotates around the hinge 23. A first contact 21 provided on the side of the arm at the substrate side and a second contact 25 provided on the substrate 12 are included. The second stage switch 30 includes a hinge 33 that includes a spring inside and is mounted on the pedestal 14, an arm 32 that rotates around the hinge 33, and a third mount that is attached to the pedestal 14 at the tip of the arm 32. The contact 31 and the 4th contact 35 provided on the base 14 are included.

  An electric wire 24 is connected to the first contact 21 of the first stage switch 20, and an electric wire 26 is connected to the second contact 25. An electric wire 34 is connected to the third contact 31 of the second stage switch 30, and an electric wire 36 is connected to the fourth contact. Each electric wire 24, 26, 34, 36 is connected to a control device 37 for vehicle air conditioning.

  In the initial state, the arm 22 of the first-stage switch 20 is positioned away from the substrate 12 by the spring inside the hinge 23, the first contact 21 is separated from the second contact 25, and is not conductive. It has become. The push button 13 is in contact with the arm 12 on the side opposite to the substrate 12 and is pushed up toward the side opposite to the substrate 12 by the force of a spring provided on the hinge 23. The arm 32 of the second switch 30 is also located at a position away from the base 14 by the spring force inside the hinge 33, and the third contact is separated from the fourth contact and is not conductive. A slight gap is formed between the substrate 12 of the first stage switch 20 and the tip of the arm 32 of the second stage switch 30 on the side opposite to the base 14.

  As shown in FIG. 2, when the push button 13 is pushed down toward the board 12 of the first stage switch 20 by the user, the lower surface of the push button 13 is opposite to the board 12 at the tip of the arm 22 of the first stage switch 20. , The hinge 23 is rotated against the spring force of the hinge 23, the tip of the arm 22 is pushed down toward the substrate 12, and the first contact 21 at the tip of the arm 22 is provided on the substrate 12. 2 Push down toward the contact point 25. At this time, since the spring 15 is harder than the spring attached to the inside of the hinge 23, even if the push button 13 is pushed down, the position of the board 12 of the first stage switch 20 in the push-down direction hardly changes. And a small gap is maintained between the front end of the arm 32 of the second stage switch 30.

  When the push button 13 is further pushed down, the first contact 21 hits the second contact 25 fixed to the substrate 12, and the first contact 21 and the second contact 25 become conductive. When the first contact 21 and the second contact 25 become conductive, the electric wires 24 and 26 become conductive, and the control device 37 for vehicle air conditioning is, for example, a first operation signal that increases the fan air volume by one step. Is output to a vehicle air conditioner (not shown).

  As shown in FIG. 3, when the push button 13 is further pushed down, the push button 13 pushes down the substrate 12 through the first contact 21 and the second contact 25 fixed to the substrate 12. Then, the spring 15 supporting the first stage switch 20 is compressed by the pressing force of the push button 13, and the entire first stage switch 20 moves together with the substrate 12 in the pressing direction. The substrate 12 hits the tip of the arm 32 of the second-stage switch 30 and pushes down the third contact at the tip of the arm 22 toward the fourth contact fixed to the base 14. When the push button 13 is further pushed down, the third contact 31 hits the fourth contact 35 and the third contact and the fourth contact are conducted. When the third contact and the fourth contact are conducted, the electric wires 34 and 36 are brought into conduction, and the control device 37 for vehicle air conditioning shows, for example, the following operation signal for continuously increasing the fan air volume. Not output to the vehicle air conditioner.

  When the push button 13 is released by the user, the push button 13, the spring 15, and the springs provided inside the hinges 23 and 33 are lifted in the direction away from the base 14 and the substrate 12 by the repulsive force of the springs. The first contact 21 and the second contact 25, and the third contact and the fourth contact are separated from each other and become non-conductive. Then, each electric wire 24, 26 and 34, 36 will be in the interruption | blocking state, and the control apparatus 37 for vehicle air conditioning will stop the output of the operation signal output previously.

  The present embodiment described above has an effect that two sets of contacts can be sequentially conducted by depressing one push button 13, and the number of switch operations can be reduced. Furthermore, since the repulsive force in the push-down direction of the push button 13 by the spring provided in the hinge 23 is set smaller than the repulsive force in the push-down direction of the spring 15, the first-stage switch 20 is turned on. The pushing force required when the second stage switch 30 is turned on and the pushing force required when the second stage switch 30 is turned on can be differentiated, and the first stage switch is pushed in by the pushing force or the second stage switch is pushed in. Since it can be judged whether it is in a state of being out, there is an effect that operability and operational feeling can be improved.

  Another embodiment will be described with reference to FIGS. 4 to 6. Parts similar to those of the embodiment described with reference to FIGS. 1 to 3 are denoted by the same reference numerals, and description thereof is omitted. As shown in FIG. 4, the two-stage push-down switch 40 for a vehicle of this embodiment has an opening in the portion of the substrate 12 that is provided with the spring 15 provided in the push-down direction of the embodiment described with reference to FIGS. 1 to 3. The elastic plate 16 is used. When the elastic plate 16 moves in the push-down direction, it has a repulsive force in the push-down direction.

  As shown in FIG. 4, the vehicular two-stage push-down switch 40 of the present embodiment is provided with an elastic plate 16 having an opening on the side surface 11 a of the housing 11, and the opening of the elastic plate 16 has the first-stage switch 20. The substrate 12 is configured to be attached. The second stage switch 30 is attached to the bottom plate 11 b of the housing 11. As in the above-described embodiment, the first stage switch 20 includes a hinge 23 provided on the substrate 12, an arm 22 rotating around the hinge 23, and a first contact 21 provided on the substrate side of the arm tip. The second stage switch 30 includes a hinge 33 attached to the bottom plate 11 b of the housing 11, an arm 32 that rotates around the hinge 33, and the arm 32. It includes a third contact 31 attached to the bottom plate 11b at the front end and a fourth contact 35 provided on the bottom plate 11b.

  The repulsive force in the push-down direction of the elastic plate 16 is configured to be larger than the repulsive force in the push-down direction by the springs provided inside the hinges 23 and 33. The elastic plate 16 may be constituted by a thin plate such as a resin, or may be constituted by a metal thin plate.

  As shown in FIGS. 5 and 6, when the push button 13 is pushed down by the user, the push button 13 pushes down the substrate 12 through the first contact 21 and the second contact 25 fixed to the substrate 12. Then, due to the pressing force of the push button 13, the elastic plate 16 supporting the first step switch 20 bends in the pressing direction, and the entire first step switch 20 moves together with the substrate 12 in the pressing direction. The substrate 12 of the switch 20 hits the tip of the arm 32 of the second-stage switch 30 and depresses the third contact toward the fourth contact. The third contact 31 hits the fourth contact 35 and the third contact 31 and the fourth contact. 35 is conducted.

  When the push button 13 is released by the user, the first contact 21, the second contact 25, and the third contact 31 are caused by the repulsive force of the springs provided inside the elastic plate 16 and the hinges 23 and 33. The fourth contacts 35 are separated from each other and return to the initial state.

  The embodiment described above has the same effect as the embodiment described above, and supports the substrate 12 of the first stage switch 20 by the elastic plate 16 in place of the spring 15 that compresses and expands in the push-down direction. Thus, the height in the push-down direction can be kept low, the overall height can be reduced, and the effect of facilitating attachment to a narrow vehicle console or the like can be achieved.

  Another embodiment will be described with reference to FIGS. As shown in FIG. 7, the two-stage push-down switch 50 for a vehicle according to the present embodiment includes a third conductive sheet 71 provided on a substrate 75 that is a base portion, and the opposite side of the third conductive sheet 71 from the substrate 75. , A second conductive sheet 61 made of an elastic material superimposed on the opposite side of the third conductive sheet 71 of the spacer 65, and a spacer 54 superimposed on the opposite side of the substrate 75 of the second conductive sheet 61. And an elastic first conductive sheet 51 superimposed on the opposite side of the spacer 54 to the second conductive sheet 61.

  The spacers 54 and 65 are provided with holes 55 and 66, respectively, in the same part. The first conductive sheet 51 is formed so as to protrude from the surface on the surface side opposite to the substrate 75 at the position of the hole 55 of the spacer 54, and includes a push-down portion 52 that is pushed down by the user. Is provided with a first contact 53. A second contact 62 is provided at a position corresponding to the first contact 53 on the first conductive sheet 51 side of the second conductive sheet 61. A third contact 63 is provided on the side surface of the second conductive sheet 61 opposite to the second contact 62. A fourth contact 72 is provided at a position facing the third contact 63 of the third conductive sheet 71.

  The first conductive sheet 51 is connected to the electric wire 56, the second contact 62 and the third contact 63 are conducted through the second conductive sheet 61, the second conductive sheet 61 is connected to the electric wire 64, and the third The conductive sheet 71 is connected to an electric wire 73, and each electric wire 56, 64, 73 is connected to a control device 74 of the vehicle air conditioner.

  In the initial state, as shown in FIG. 7, the first contact 53 and the second contact 62 are separated by a spacer 54 and are in a cut-off state, and the third contact and the fourth contact are separated by a spacer 65, Blocked state.

  As shown in FIG. 8, when the push-down portion 52 of the first conductive sheet 51 is pushed down by the user, the first conductive sheet 51 is elastically deformed and the first conductive sheet 51 is pushed down into the hole 55 of the spacer 54. The first contact 53 is in contact with the second contact 62 of the second conductive sheet 61, and the first contact 53 and the second contact 63 are in a conductive state. Then, the electric wires 56 and 64 become conductive, and the vehicle air conditioning control device 74 outputs, for example, a first operation signal that increases the fan air flow by one step to a vehicle air conditioning device (not shown).

  Then, as shown in FIG. 9, when the push-down portion 52 is further pushed down by the user, the first conductive sheet 51 is further elastically deformed, and the second conductive sheet is elastically deformed and pushed down into the hole 66 of the spacer 65. The third contact 63 of the second conductive sheet 61 is in contact with the fourth contact 72 of the third conductive sheet 71, and the third contact 63 and the fourth contact 72 are in a conductive state. At this time, since the first contact 53 and the second contact 62 are also in a conductive state, all of the first to fourth contacts 53, 62, 63, 72 are in a conductive state. And the electric wires 56, 64, and 73 will be in a conduction | electrical_connection state. When the first contact 53 and the second contact 62 are conducted, the vehicle air conditioning control device 74 outputs, for example, an operation signal that increases the fan air volume by one step to a vehicle air conditioning device (not shown). When the contact 63 and the fourth contact 72 are brought into conduction, the vehicle air conditioning control device 74 outputs, for example, a next operation signal that continuously increases the fan air volume to a vehicle air conditioning device (not shown).

  When the depression of the push-down portion 52 is released by the user, the first and second conductive sheets 51 and 61 are repelled and raised by their elastic force, return to the initial state, the first contact 53 and the second contact 62, In addition, the third contact 63 and the fourth contact 72 are separated from each other and do not conduct. Then, each electric wire 56, 64, and 73 will be in the interruption | blocking state, and the control apparatus 74 for vehicle air conditioning will stop the output of the operation signal output previously.

  In addition to the effect that the number of operations of the push-down portion 52 can be reduced, the present embodiment described above only elastically deforms the first conductive sheet 51 when the first contact and the second contact are brought into contact. The push-down portion 52 is pushed down by force, and when the third contact and the fourth contact are brought into contact, the push-down portion 52 is pushed down by a force that elastically deforms the second conductive sheet 61 together with the first conductive sheet 51. Therefore, a difference is made between the pushing force when the first contact 53 and the second contact 62 are brought into conduction and the pushing force necessary when the third contact 63 and the fourth contact 72 are brought into conduction. It is possible to determine whether the first contact 53 and the second contact 62 are electrically connected by the pushing force, or whether the third contact 63 and the fourth contact 72 are electrically connected. Improve performance and feel To be an effect that it is.
