The inner wall 22 of the motor housing may be disposed on the base 21. In this embodiment, the extending direction D1 may be parallel to the rotation axis AX1. In some embodiments, the inner wall 22 of the motor housing can be integrally formed with the base 21 and can have the same material. In some embodiments, the inner wall 22 of the motor housing and the base 21 can be made of a thermally conductive material, such as metal or ceramic, but not limited to this.

The stator 11 and the rotor 12 of the motor assembly 10 can be placed in the accommodating space S1. In addition, the stator 11 can be connected and fixed to the inner side of the inner wall 22 of the motor housing, that is, the outer edge of the accommodating space S1. Therefore, in this embodiment, the heat generated by the motor assembly 10 can be directly transferred to the inner wall 22 of the motor housing, thereby dissipating heat from the motor assembly 10.

The outer wall 23 of the motor housing may be disposed on the base 21 and may surround the inner wall 22 of the motor housing. In this embodiment, the motor housing outer wall 23 may have a first connecting surface 231 that contacts the driver housing 40. The tangent direction of the first connection surface 231 may extend along the extending direction D1. In some embodiments, the outer wall 23 of the motor housing is detachably disposed on the base 21 and/or the inner wall 22 of the motor housing, so as to facilitate the assembly and/or maintenance of the water-cooled motor-drive integrated machine 1. The outer wall 23 of the motor housing can be made of a thermally conductive material, such as metal or ceramic, but not limited to this. In this embodiment, the heat generated by the inner wall 22 of the motor housing can be indirectly transferred to the outer wall 23 of the motor housing, thereby dissipating heat from the motor assembly 10.

The top 24 may be disposed and covered on the inner wall 22 of the motor housing and the outer wall 23 of the motor housing. The top 24 may be a hollow structure, and surround and house the electrical connector 13. In some embodiments, the top 24 is detachably disposed and covered on the inner wall 22 of the motor housing and/or the outer wall 23 of the motor housing, so as to facilitate maintenance of the water-cooled motor-drive integrated machine 1. In this embodiment, the top 24 may include an upper body 241 and an upper cover 242. The upper body 241 includes an accommodating space 2411 and a first connection port 2412. The electrical connector 13 can be placed in the accommodation space 2411, and the first connection port 2412 communicates with the accommodation space 2411. The upper cover 242 is detachably disposed on the upper body 241 and covers the accommodating space 2411.

The driver housing 40 is disposed and attached to the motor housing 20. The inside of the driver housing 40 may be a hollow structure, and is used to accommodate the driver assembly 30. The driver housing 40 may include a body portion 41, a cover 42 and a sealing ring 43. The main body 41 has a second connecting surface 411 outside.

The second connecting surface 411 may be parallel to the first connecting surface 231, that is, the tangent direction of the second connecting surface 411 may extend along the extending direction D1. In this embodiment, the first connecting surface 231 and the second connecting surface 411 may be smooth and flat, but not limited to this. In addition, the first connection surface 231 contacts at least 70% of the area of the second connection surface 411, but it is not limited thereto.

In this embodiment, the body portion 41 and/or the cover 42 can be made of a thermally conductive material, such as metal or ceramic, but not limited to this. The driver assembly 30 is connected and attached to the corresponding position in the hollow structure of the body portion 41, so the heat generated by the driver assembly 30 can be directly conducted to the body portion 41, and the heat of the body portion 41 can also pass through the second connection surface 411 and the first The connecting surface 231 is directly conducted to the outer wall 23 of the motor housing.

In this embodiment, it may further include applying a thermal conductive material M1 between the first connection surface 231 and/or the second connection surface 411. In some embodiments, the thermal conductive material M1 is distributed over at least 70% of the area of the first connection surface 231 and/or the second connection surface 411. In other words, the first connection surface 231 indirectly contacts the second connection surface 411 via the thermally conductive material M1. In some embodiments, the thermal conductive material M1 may not be needed, and the first connection surface 231 directly contacts the second connection surface 411, as described above.

In this embodiment, the body portion 41 of the driver housing 40 can have an accommodating space 412 and a second connection port 413. The driver assembly 30 can be disposed in the accommodating space 412. The second connection port 413 is formed on the second connection surface 411 and can communicate with the accommodating space 412. Therefore, the wires or signal wires (not shown) matched with the driver assembly 30 in the driver housing 40 can be connected to the electrical connection in the top 24 through the second connection port 413 and the first connection port 2412 of the motor housing 20器13. 13.

In this embodiment, the motor housing 20 may further include a sealing ring 25 disposed between the upper body 241 and the second connection surface 411 of the body portion 41 of the driver housing 40. The sealing ring 25 can be used to prevent cooling liquid L1 (as shown in FIGS. 3 and 4) or liquids such as water from flowing into the top 24 through the first connection port 2412, thereby preventing the electrical connector 13 from short-circuiting. In addition, the sealing ring 25 can also be used to prevent liquids such as cooling liquid L1 or water from flowing into the driver housing 40 through the second connection port 413 of the driver housing 40 and to prevent the driver assembly 30 from short circuiting.

The body portion 41 of the driver housing 40 may further include one or more wire holes 414. A wire (not shown) may be connected to the driver assembly 30 from the outside of the driver housing 40 via a wire hole 414 to supply driver power to the driver assembly 30.

The cover 42 of the driver housing 40 is detachably disposed on the main body 41 and covers the accommodating space 412. The seal ring 43 is provided between the body 41 and the cover 42. The seal ring 43 can be used to prevent liquids such as cooling liquid L1 and water from flowing into the accommodating space 412 through the body portion 41 and the cover 42, and to prevent the driver assembly 30 from being short-circuited.

The driver assembly 30 may include a driving electrical connector 31 disposed on the cover 42. The driving electrical connector 31 can be coupled to an external control device (not shown), and receives operation signals transmitted by the control device.

FIG. 3 is a partial perspective view of the first embodiment of the disclosed motor housing 20. FIG. 4 is a schematic diagram of the first embodiment of the disclosed motor housing 20 and driver housing 40. As shown in FIGS. 2 to 4, the motor housing 20 further includes a water inlet T1, a heat dissipation channel T2, and a water outlet T3. The water inlet T1 communicates and is provided on the outer wall 23 of the motor housing. One end of the heat dissipation flow channel T2 is connected to the water inlet T1. The heat dissipation flow channel T2 can contact and accommodate between the motor housing inner wall 22 and the motor housing outer wall 23. In other words, the heat dissipation flow channel T2 may be partially formed on the inner wall 22 of the motor housing or partially formed on the outer wall 23 of the motor housing. In some embodiments, part of the heat dissipation flow channel T2 is formed on the inner wall 22 of the motor housing, and part of the heat dissipation flow channel T2 is formed on the outer wall 23 of the motor housing. In this embodiment, the heat dissipation flow channel T2 is disposed around the outer surface of the inner wall 22 of the motor housing. The water outlet T3 communicates with and is provided on the outer wall 23 of the motor housing, and is connected to the other end of the heat dissipation channel T2.

In this embodiment, the water inlet T1 may be connected to an external water pump (not shown) through a pipeline. An external water pump supplies cooling liquid L1 into the water inlet T1. The cooling liquid L1 flows into the heat dissipation channel T2 through the water inlet T1 and circulates. The cooling liquid L1 in the heat dissipation flow channel T2 is discharged through the water outlet T3. The water outlet T3 may be connected to the water pump through another pipeline, so that the cooling liquid L1 circulates and flows in the heat dissipation channel T2.

In this embodiment, the heat dissipation flow channel T2 has an input section T21, a cooling section T22, and a surrounding section T23. The input section T21 is connected to the water inlet T1 and the cooling section T22. The input section T21 may be formed outside the inner wall 22 of the motor housing and/or the motor housing 20 (for example, a pipe connected to the water inlet of the water pump). Since the inner wall 22 of the motor housing can be a hollow cylindrical structure, the input section T21 can be arc-shaped, but not limited to this.

The cooling section T22 is disposed corresponding to the first connecting surface 231 of the motor housing 20, and both ends of the cooling section T22 are respectively connected to the input section T21 and the surrounding section T23. In this embodiment, the cooling section T22 of the heat dissipation flow channel T2 corresponds to the first connecting surface 231 in a meandering configuration. In addition, the cooling section T22 is separated from the first connection surface 231 or maintained at an appropriate distance. The cooling section T22 may be extended along a plane parallel to the first connecting surface 231. In other words, the cooling section T22 may be extended along a normal direction D2 perpendicular to the first connection surface 231. In this embodiment, the normal direction D2 of the first connection surface 231 may be perpendicular to the extending direction D1. In addition, the cross-sectional area of the cooling section T22 projected on the first connection surface 231 is greater than 50% of the area of the first connection surface 231. The cross-sectional area is measured on a plane parallel to the first connection surface 231.

In this embodiment, since the cooling section T22 is meanderingly arranged and extending along the first connecting surface 231, and the cooling liquid L1 circulates in the cooling section T22, the cooling liquid L1 can be taken away from the driver housing 40 for conduction The heat to the outer wall 23 of the motor housing dissipates heat to the driver assembly 30.

The two ends of the surrounding section T23 are respectively connected to the cooling section T22 and the water outlet T3. The surrounding section T23 may be formed on the inner wall 22 of the motor housing and/or the outer shell of the motor housing 20. In this embodiment, the surrounding section T23 may be a spiral structure. The surrounding section T23 may surround the rotation axis AX1 and spirally extend toward the extending direction D1. In this embodiment, the surrounding section T23 surrounds at least two turns of the rotation axis AX1, that is, at least two turns of the outer side of the motor assembly 10.

In this embodiment, since the surrounding section T23 spirally extends along the inner wall 22 of the motor housing, and the cooling liquid L1 circulates in the surrounding section T23, the cooling liquid L1 can take away the motor assembly 10 and conduct into the motor housing The heat of the wall 22 and the outer wall 23 of the motor housing further radiates heat to the motor assembly 10. In addition, through the design of the motor housing 20 and the driver housing 40 of the present disclosure, the heat generated by the driver assembly 30 can be radiated by the cooling system circulating in the motor housing 20, and no additional configuration is required for the driver assembly 30 A cooling device can further save the manufacturing cost of the water-cooled motor driver integrated machine 1. In addition, the heat dissipation flow channel T2 of the present disclosure can be attached to the surface of the motor housing 20, and the motor housing 20 is made of a thermally conductive material, so better heat dissipation efficiency can be achieved. In addition, this embodiment is assembled separately and is independent, which has the advantages of easy disassembly and convenient maintenance.

FIG. 5 is an exploded view of the second embodiment of the disclosed water-cooled motor driver integrated machine 1. FIG. 6 is a schematic diagram of the second embodiment of the disclosed motor housing 20 and driver housing 40. The second embodiment has a similar structure to the first embodiment, and substantially the same parts will be simplified and described as appropriate. In this embodiment, the portion of the cooling section T22 of the heat dissipation flow channel T2 may overlap the first connection surface 231. In other words, the cooling section T22 may be partially formed on the first connection surface 231. The second connection surface 411 of the driver housing 40 can cover the exposed cooling section T22, and can be connected and attached to the exposed cooling section T22, further improving heat dissipation efficiency and power density.

Therefore, in this embodiment, the exposed cooling section T22 (cooling liquid L1 inside) can directly contact the driver housing 40, and then directly take away the heat conducted by the driver assembly 30 to the driver housing 40. Therefore, the heat dissipation efficiency of the cooling liquid L1 to the driver assembly 30 can be further improved.

In some embodiments, a portion of the cooling section T22 overlaps the second connection surface 411. In other words, the cooling section T22 can be formed deeper on the second connection surface 411. Therefore, the contact area of the cooling section T22 (the cooling liquid L1) overlapping the second connection surface 411 with the driver housing 40 can be further increased, thereby further improving the heat dissipation efficiency of the cooling liquid L1 to the driver assembly 30.

In this embodiment, the motor housing 20 may further include a sealing ring 26, and one side of the sealing ring 26 is disposed on the first connecting surface 231 of the outer wall 23 of the motor housing. The other side of the sealing ring 26 can be connected to the second connecting surface 411 of the driver housing 40. With this design, the sealing ring 26 can be used to prevent the cooling liquid L1 in the cooling section T22 from flowing out through the gap between the first connection surface 231 and the second connection surface 411, and protect the motor assembly 10 or the driver assembly 30 from short circuit. The embodiment of the second embodiment is similar to the foregoing first embodiment, and is a separate assembly form, and its additional advantages will not be repeated.

FIG. 7 is a perspective view of the third embodiment of the disclosed water-cooled motor driver integrated machine 1. FIG. 8 is an exploded view of the third embodiment of the disclosed water-cooled motor driver integrated machine 1. FIG. 9 is a schematic diagram of a third embodiment of the disclosed motor housing 20 and driver housing 40. The third embodiment has a similar structure to the first embodiment, and substantially the same parts will be simplified for explanation. In the third embodiment, the water-cooled motor driver integrated machine 1 may not include the driver housing 40. The inner wall 22 of the motor housing surrounds and houses the motor assembly 10. The motor housing outer wall 23 surrounds the motor housing inner wall 22.

In this embodiment, the outer wall 23 of the motor housing further has an accommodating groove 232 for accommodating the driver assembly 30. The accommodating groove 232 includes a first connection surface (connection surface) 231, an annular side wall 233, and a cover plate 27, and the driver assembly 30 can be attached to different sides of the first connection surface (connection surface) 231 relative to the motor assembly 10. The annular side wall 233 is connected to the first connection surface (connection surface) 231. In this embodiment, the annular side wall 233 may be vertical or substantially perpendicular to the first connection surface (connection surface) 231, and together with the first connection surface (connection surface) 231 define and form an accommodating groove 232 to accommodate Driver assembly 30.

In this embodiment, the motor housing outer wall 23 can be connected to the top 24. The motor housing outer wall 23 may have a third connection port (connection port) 234. The third connection port (connection port) 234 can communicate with the accommodating groove 232. The third connection port (connection port) 234 may correspond to the first connection port 2412. In other words, the accommodating groove 232 can communicate with the accommodating space 2411 via the third connection port (connection port) 234 and the first connection port 2412.

The motor housing 20 may further include a cover plate 27 and a sealing ring 28. The cover plate 27 is detachably provided and connected to the annular side wall 233. The cover plate 27, the first connecting surface (connecting surface) 231 and the annular side wall 233 together define an accommodating groove 232 and surround the driver assembly 30. The seal ring 28 is provided between the annular side wall 233 and the cover plate 27. The seal ring 28 can be used to prevent liquids such as cooling liquid L1 and water from flowing into the accommodating groove 232 through the annular side wall 233 and the cover plate 27.

In this embodiment, since the driver assembly 30 is directly disposed in the accommodating groove 232 of the outer wall 23 of the motor housing, and is attached to the first connection surface (connection surface) 231, the heat generated by the driver assembly 30 can be directly transmitted to the motor The outer wall 23 of the housing can be radiated through the cooling liquid L1 of the heat dissipation flow channel T2 in the motor housing 20, thereby further improving the heat dissipation efficiency and power density of the driver assembly 30. In addition, in this embodiment, since the driver housing 40 may not be included, the assembly and cost of the water-cooled motor driver integrated machine 1 can be simplified, and the integrated non-stick design not only strengthens the structure, but also reduces the effect of reducing the waterproof interface. In addition, this embodiment is an integrated assembly structure, which has the advantages of sharing molds, reducing materials, and reducing assembly costs.
