[0031] New energy vehicles are becoming more and more popular, compared with traditional internal combustion engine vehicles, the motor structure of new energy vehicles is more simplified, the structure is more compact, and the power output is stronger, and when the brake energy is recovered, the torque is reversed. But the motor is usually connected with the bushing, and the bushing is connected with the vehicle body or the auxiliary frame of the vehicle body, so that the motor is installed on the vehicle body, and when the motor outputs and recovers the brake energy, the motor itself and the vehicle body will be subjected to a larger impact. In the prior art, this requires the motor to have a large structural strength. Therefore, it is urgent to design a motor assembly to load the large torque generated by the motor.

[0032] To solve the above problems, the application provides a vehicle, which comprises the following motor housing assembly, and the motor housing assembly is connected with the vehicle body. Specifically, the vehicle body can comprise an auxiliary frame, the motor housing assembly is connected with the auxiliary frame, and then the motor housing assembly is installed on the vehicle body.

[0034] The vehicle motor housing assembly 10 comprises a bushing 100, a motor housing main body 200 and a bushing 100 connecting piece, the bushing 100 is used for connecting with the vehicle body; the motor housing main body 200 is formed with a mounting groove 210 at a position corresponding to the bushing 100; the bushing 100 connecting piece comprises a bushing connecting part 310 and a force transmission part 320, one end of the bushing connecting part 310 is connected with the bushing 100, the other end is located in the mounting groove 210 and is connected with the motor housing main body 200, and the force transmission part 320 is connected with the side walls of the motor housing main body 200 and the bushing connecting part 310 respectively.

[0035] The bushing 100 is connected to the motor housing assembly 10 and the vehicle body, and specifically, the bushing 100 can be embedded in the vehicle body or the subframe 20 connected to the vehicle body. The bushing 100 can include an inner sleeve, an outer sleeve, and an elastic body between the inner sleeve and the outer sleeve. The inner sleeve is connected to the bushing 100 connector connected to the motor housing body, and the outer sleeve can be located in the embedded hole on the subframe 20, so that the motor housing assembly 10 is connected to the vehicle body, and the bushing 100 can reduce noise, improve comfort, and prolong the service life of the components. Further, the end of the elastic body close to the bushing 100 connector can protrude from the inner sleeve and the outer sleeve, and the end of the elastic body close to the bushing 100 connector abuts against the bushing 100 connector, so that the bushing 100 and the bushing 100 connector can be flexibly contacted, thereby reducing resonance.

[0036] The inside of the motor housing body 200 is used to accommodate core components, such as stators, rotors, bearings, and other components, which are used to power the vehicle. The outside of the motor housing body 200 is formed with a mounting groove 210 corresponding to the bushing 100, so that the bushing 100 connector can connect the electrode housing body and the bushing 100, and then fix the motor housing body 200 to the vehicle body. It can be understood that, Figure 1 The motor housing body 200 shown only shows a part, which includes the bushing 100 connector and the bushing 100 connected to the motor housing body 200. Of course, the motor housing body 200 can include a plurality of bushing 100 connectors and bushings 100, one bushing 100 connector and one bushing 100 are matched, so that the motor housing assembly 10 can be fixedly connected to the vehicle body through a plurality of bushing 100 connectors and bushings 100.

[0037] The sleeve 100 connecting part is located in the mounting groove 210, and is used to connect the motor housing body 200 to the sleeve 100. The sleeve 100 connecting part can include a sleeve connecting portion 310 and a force transmission portion 320. One end of the sleeve connecting portion 310 is located in the mounting groove 210 and connected to the motor housing body 200, and the other end of the sleeve connecting portion 310 is connected to the sleeve 100. The force transmission portion 320 is connected to the side wall of the motor housing body 200 and the sleeve connecting portion 310, respectively, so as to support the sleeve connecting portion 310. Specifically, one end of the sleeve connecting portion 310 can be connected to the bottom surface of the mounting groove 210. One side surface of the force transmission portion 320 is connected to the side wall of the sleeve connecting portion 310, and the other adjacent side surface of the force transmission portion 320 is connected to the bottom surface of the mounting groove 210. The force transmission portion 320 has a certain height relative to the bottom surface, so that the force transmission portion 320 can bear a part of the shear force for the sleeve connecting portion 310. In addition, the motor housing body 200 and the sleeve 100 connecting part can be integrally arranged, that is, the motor housing body 200 and the sleeve 100 connecting part are formed by integral casting. Compared with the sleeve 100 connecting part being connected to the motor housing body 200 by bolts and welding, the integral arrangement makes the contact surface of the sleeve connecting portion 310 and the motor housing body 200 larger, and the force transmission portion 320 is more firmly connected to the sleeve connecting portion 310.

[0038] According to the above embodiment, the sleeve connecting portion 310 of the sleeve 100 connecting part is connected to the vehicle body through the sleeve 100, and the force transmission portion 320 is connected to the side wall of the sleeve connecting portion 310 and the motor housing body 200, respectively. When the sleeve 100 connecting part is subjected to a large torque, the force transmission portion 320 can support the sleeve connecting portion 310, thereby improving the load capacity of the sleeve 100 connecting part and the ability of the motor housing body 200 to resist torque.

[0039] In some embodiments, the number of force transmission portions 320 is multiple, and the multiple force transmission portions 320 are arranged at intervals along the circumference of the sleeve connecting portion 310. Each force transmission portion 320 is connected to the side wall of the motor housing body 200 and the sleeve connecting portion 310, respectively. The number of force transmission portions 320 can be multiple, and the multiple force transmission portions 320 can be arranged at intervals along the circumference of the sleeve connecting portion 310.

Thus, the multiple force transmission portions 320 can collectively bear more shear force for the sleeve connecting portion 310, and can bear the shear force received by the sleeve connecting portion 310 from different angles, thereby improving the load capacity of the sleeve 100 connecting part. The force transmission portion 320 can be block-shaped or plate-shaped. Alternatively, the force transmission portion 320 is plate-shaped, that is, the thickness of the force transmission portion 320 is smaller than the length and height. The force transmission portion 320 is vertically arranged, so that the number of force transmission portions 320 can be larger, and the overall weight of the sleeve 100 connecting part can be reduced, thereby achieving the purpose of lightweight.

[0040] In some embodiments, the sleeve connecting part 310 is cylindrical, and the plurality of force transmission parts 320 are circumferentially spaced and uniformly arranged on the sleeve connecting part 310. The sleeve connecting part 310 is cylindrical, so that the plurality of force transmission parts 320 can be circumferentially spaced and uniformly arranged on the sleeve connecting part 310, the force of the plurality of force transmission parts 320 is more uniform, and the risk of damage to the sleeve 100 connecting part due to uneven force of each force transmission part 320 is reduced. Further, the plurality of force transmission parts 320 can be uniformly spaced and symmetrically arranged along the circumference of the sleeve connecting part 310, that is, one force transmission part 320 corresponds to an opposite force transmission part 320, thereby further reducing the risk of damage to the sleeve 100 connecting part.
