In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only for the purpose of convenient description and cannot be understood as indicating or implying relative importance.

[0035] As Figures 1 to 4 shown, the motor electronic control integrated device of the present application includes an electronic control housing 1, a cooling housing part 2, an electronic control module 3, and a motor housing 4. The electronic control housing 1 is connected to the end of the motor housing 4, and the cooling housing part 2 and the electronic control module 3 are arranged in the electronic control housing 1. The cooling housing part 2 is used to cool the electronic control module 3, thereby improving the working efficiency and service life of the electronic control module 3.

[0036] In one embodiment, in order to integrate the motor system and the electronic control system together, and avoid the excessive size of the integrated components and increase the mold development cost, the electronic control housing 1 and the motor housing 4 are detachably connected. With such a setting, the manufacturing of the rear end cover of the motor housing 4 can also be omitted through the electronic control housing 1, reducing the manufacturing cost, and at the same time facilitating the subsequent maintenance and disassembly of the motor electronic control integrated device.

[0037] Further in combination with Figure 5 andFigure 6 As shown, the electric control housing 1 is provided with a cooling channel 11, and the cooling channel 11 is respectively connected with the cooling housing 2 and the motor housing 4. Specifically, the external coolant can flow into the cooling housing 2 from the cooling channel 11, and the coolant in the cooling housing 2 flows into the motor housing 4 through the cooling channel 11. Such a configuration simplifies the cooling system and reduces the manufacturing cost.

[0038] Furthermore, the cooling channel 11 includes a liquid inlet channel 111 and a liquid outlet channel 112. One end of the liquid inlet channel 111 is connected to the cooling shell 2, and the liquid outlet channel 112 is respectively connected to the cooling shell 2 and the motor housing 4. In order to allow the external coolant to better enter the liquid inlet channel 111, the electric control housing 1 is provided with a liquid inlet connector 15, and the liquid inlet connector 15 is provided on the outer surface of the electric control housing 1, and is connected to the other end of the liquid inlet channel 111 away from the cooling shell 2.

[0039] In one embodiment, the electric control housing 1 includes a main housing 13 and a cover 14. The main housing 13 is detachably connected to the motor housing 4, and the cover 14 is connected to the side of the main housing 13 away from the motor housing 4. The cooling shell 2 and the electric control module 3 are located in the main housing 13, and the cover 14 is used to close the main housing 13.

[0040] The main housing 13 includes a bottom plate 131, a rib 132, a cooling portion 133 and a copper busbar mounting portion 134. The rib 132 extends from the bottom plate 131 in a direction away from the motor housing 4, and the rib 132 and the bottom plate 131 form a cavity for accommodating the cooling shell 2 and the electronic control module 3. The cooling portion 133 is provided on the bottom plate 131, and the liquid inlet channel 111 and the liquid outlet channel 112 penetrate the cooling portion 133 along the direction from the electronic control housing 1 to the motor housing 4. The copper busbar mounting portion 134 is provided on the bottom plate 131 for mounting the copper busbar.

[0041] In order to facilitate the connection between the connector in the electric control housing 1 and the external power supply, the electric control housing 1 is provided with a connector housing 16. The connector housing 16 is provided on the outer peripheral surface of the main housing 13, and the internal cavity of the connector housing 16 is connected to the cavity of the main housing 13. The connector housing 16 can be used to accommodate components such as connectors and transformers.

[0042] Further integration Figures 7 to 9 As shown, in one embodiment, the cooling shell 2 is detachably disposed in the electric control housing 1 to facilitate subsequent disassembly and maintenance of the cooling shell 2. Of course, the cooling shell 2 can also be integrally manufactured with the electric control housing 1 to improve the stability of the cooling shell 2 after installation.

[0043] The cooling housing 2 is connected between the electronic control module 3 and the electronic control housing 1, such that while cooling the electronic control module 3, the cooling housing 2 can also cool the electronic control housing 1. To further improve the cooling effect of the cooling housing 2, one side of the cooling housing 2 abuts against the bottom wall 12 of the electronic control housing 1, the opposite side closely abuts against the electronic control module 3, and part of the electronic control module 3 is located within the cooling housing 2.

[0044] The cooling housing 2 is provided with a cooling cavity 21, a cooling substrate 22, and a connecting plate 23. The cooling cavity 21 is located at the middle position of the cooling housing 2, and the cooling cavity 21 communicates with the cooling channel 11. Specifically, the cooling cavity 21 communicates with the liquid inlet channel 111 and the liquid outlet channel 112 respectively. The external coolant enters the cooling cavity 21 from the liquid inlet channel 111 and then flows into the motor housing 4 from the liquid outlet channel 112.

[0045] Along the direction from the electronic control housing 1 to the motor housing 4, the cooling cavity 21 penetrates through the connecting plate 23 and the cooling substrate 22. And in this direction, the electronic control module 3 abuts against the connecting plate 23, the bottom wall 12 abuts against the cooling substrate 22, and the electronic control housing 1 seals the cooling cavity 21 by means of the electronic control module 3 and the bottom wall 12. Part of the electronic control module 3 is located within the cooling cavity 21.

[0046] Furthermore, the cooling substrate 22 is connected to the bottom wall 12 of the electronic control housing 1, and the connecting plate 23 is located on the side of the cooling substrate 22 facing away from the bottom wall 12. The cooling cavity 21 is provided between the cooling substrate 22 and the connecting plate 23, that is, along the direction from the electronic control housing 1 to the motor housing 4, the cooling cavity 21 can either penetrate through the connecting plate 23 and the cooling substrate 22, or penetrate through the connecting plate 23 and part of the cooling substrate 22.

[0047] The cooling substrate 22 and the bottom wall 12 of the electronic control housing 1 can be fixed by means of screwing, bonding, etc. To ensure prevention of coolant spillage, sealing elements are provided between the bottom wall 12 and the cooling substrate 22, and between the electronic control module 3 and the connecting plate 23.

[0048] Further in combination with Figures 10 to 12 As shown, the cooling substrate 22 is provided with a cooling liquid inlet channel 221 and a cooling liquid outlet channel 222. The cooling liquid inlet channel 221 communicates with the liquid inlet channel 111 and the cooling cavity 21 respectively. The cooling liquid outlet channel 222 communicates with the cooling cavity 21 and the liquid outlet channel 112 respectively. The external coolant enters the cooling liquid inlet channel 221, the cooling cavity 21, and the cooling liquid outlet channel 222 in sequence from the liquid inlet channel 111, and finally flows into the motor housing 4 from the liquid outlet channel 112.

[0049] To prevent coolant leakage, sealing elements are provided at the joints of the cooling liquid inlet channel 221 and the liquid inlet channel 111, and at the joints of the cooling liquid outlet channel 222 and the liquid outlet channel 112. The sealing elements are preferably located at the cooling part 133.

[0050] The cooling substrate 22 includes a cooling support plate 223 and a sealing support plate 224. One side of the sealing support plate 224 is sealed to the cooling support plate 223, and the other side is close to the bottom wall 12. The cooling liquid inlet channel 221 and the cooling liquid outlet channel 222 are located between the cooling support plate 223 and the sealing support plate 224.

[0051] The inlet 2211 of the cooling liquid inlet channel 221 and the outlet 2221 of the cooling liquid outlet channel 222 are arranged on the same side of the sealing support plate 224, and the inlet 2211 is communicated with the liquid inlet channel 111, and the outlet 2221 is communicated with the liquid outlet channel 112. The bottom wall 12 is arranged on the bottom plate 131. To ensure the sealing between the inlet 2211 and the liquid inlet channel 111 and the outlet 2221 and the liquid outlet channel 112, the side 1331 of the cooling portion 133 is flush with the bottom wall 12, and the sealing support plate 224 is respectively attached to the bottom wall 12 and the side 1331 of the cooling portion 133.

[0052] In one embodiment, the cooling support plate 223 includes a partition rib 2231 and a top block 2232. The cooling liquid inlet channel 221 is located on one side of the partition rib 2231, and the cooling liquid outlet channel 222 and the cooling cavity 21 are located on the side of the partition rib 2231 away from the cooling liquid inlet channel 221. Specifically, the partition rib 2231 divides the cavity inside the cooling substrate 22 into the cooling liquid inlet channel 221 and the cooling liquid outlet channel 222. The partition rib 2231 abuts against the sealing support plate 224, that is, the partition rib 2231 protrudes from the bottom side of the cooling support plate 223 and is in sealing contact with the sealing support plate 224.

[0053] The top block 2232 is bent and extended from a side of the cooling support plate 223 away from the cooling liquid outlet 222. The top block 2232 contacts the bottom wall 12 to prevent the cooling substrate 22 from tilting, so that the cooling substrate 22 is kept horizontally arranged, thereby ensuring that the sealing support plate 224 is closely attached to the bottom wall 12 and the side surface 1331 of the cooling portion 133 to prevent the cooling liquid from leaking.

[0054] In one embodiment, the electric control module 3 is connected to the connecting plate 23 of the cooling housing 2. The electric control module 3 includes a cooling member group 31 and a module body 32. The cooling member group 31 protrudes from the module body 32 toward the motor housing 4. At least part of the cooling member group 31 is located in the cooling housing 2, and further, at least part of the cooling member group 31 is located in the cooling cavity 21, and the module body 32 is connected to the connecting plate 23.

[0055] In order to improve the cooling efficiency of the cooling shell 2 on the electric control module 3, the cooling member group 31 is completely located in the cooling cavity 21. Along the direction from the electric control housing 1 to the motor housing 4, the cooling member group 31 does not exceed the sealing support plate 224. The cooling member group 31 is a densely distributed needle-shaped structure. The electric control module 3 is an IGBT module (insulated gate bipolar transistor).

[0056] The motor housing 4 is provided with a coolant passage 41, and the coolant passage 41 is communicated with the liquid outlet passage 112. With such a setting, the motor housing 4, the electronic control housing 1 and the cooling housing member 2 can be cooled together, and there is no need for an external hose connection between the motor housing 4 and the electronic control housing 1, which simplifies the cooling system and saves the assembly layout space and cost.

[0057] In the motor and electronic control integrated device of the present application, the electronic control housing 1 is connected to the end of the motor housing 4, so that the motor system and the electronic control system can be integrated together, the manufacturing of the motor rear end cover can be omitted, and the manufacturing cost and the mold development cost can be reduced. And by providing the cooling housing member 2 and part of the cooling member group 31 is located in the cooling housing member 2, the cooling housing member 2 can better cool the electronic control module 3 to improve the working efficiency of the electronic control module 3. At the same time, the cooling housing member 2 is detachably arranged in the electronic control housing 1, which is convenient for the disassembly and maintenance of the cooling housing member 2.
