[0038] In some embodiments, the box body 610 is further provided with a second avoidance hole 612, the second avoidance hole 612 is arranged opposite to the motor 200, and the front end of the motor 200 is penetrated through the second avoidance hole 612. That is to say, the box body 610 is also suitable for constructing a second avoidance hole 612, the second avoidance hole 612 is arranged opposite to the motor 200, so that the volume of the first partition 600 can be reduced, the production materials can be reduced, the production cost can be reduced, and the first partition 600 can be more reliably covered at the connection between the commutator 300 and the brush 400. In addition, during the use of the first partition 600, it is suitable to set the first partition 600 correspondingly at the connection between the brush 400 and the commutator 300, so that the generated debris can enter the first partition 600 for collection, thereby avoiding the subsequent influence of the debris on the use of the motor assembly 10, so that the use performance of the motor assembly 10 is improved.

After that, the first clamping part and the second clamping part are constructed on the box body 610 and the box cover respectively, so that the first clamping part and the second clamping part are clamped to achieve the assembly setting of the first partition 600, simplifying the use process, and having a high structural strength to meet the use, so that the use of the motor assembly 10 is more reliable.

[0041] In some embodiments, the motor assembly 10 further includes: a second partition 700, the second partition 700 is disposed in the accommodating space 101, the second partition 700 is spaced apart from the first partition 600, and the second partition 700 is interference-set in the housing 100, and the second partition 700 is disposed on the side of the first partition 600 away from the motor 200. In this way, during the use of the motor assembly 10, it is also suitable to include the second partition 700, and the second partition 700 is suitable to be constructed on the side of the first partition 600 away from the motor 200, so that when the oil is suitable for breaking through the oil seal for circulation, it is suitable for further sealing through the second partition 700, so that the oil circulating through the oil seal is suitable for further sealing through the second partition 700, so as to further prevent the oil from mixing with fines to affect the use of the motor assembly 10, so that the motor assembly 10 has higher performance to meet the driving requirements of the vehicle.

The sealing portion 720 is disposed at the edge of the partition main body 710, and the cross-sectional width of the sealing portion 720 is greater than the cross-sectional width of the partition main body 710. That is to say, the sealing portion 720 is provided at the edge of the partition main body 710. Since the cross-sectional width of the sealing portion 720 is greater than the cross-sectional width of the partition main body 710, the sealing portion 720 can be more reliably sealed in the housing 100 to prevent the oil fluid from flowing and contacting the fine chips, thereby improving the reliability of the use of the motor assembly 10.

[0043] In some embodiments, the sealing portion 720 is in interference fit with the inner peripheral wall of the housing 100. It can be understood that by making the sealing portion 720 in interference fit with the inner peripheral wall of the housing 100, the second partition portion 700 can be more reliably arranged in the housing 100. In this way, the second partition portion 700 has higher sealing performance to prevent the oil fluid from flowing, so that the use performance of the motor assembly 10 is more reliable, and thus the motor assembly 10 can provide higher output power to meet the driving requirements of the vehicle.

In this way, by setting the second partition portion 700 as an integrally formed structural member, the production steps of the second partition portion 700 can be saved, the production process of the motor assembly 10 can be simplified, and the connection strength between the second partition portion 700 and the housing 100 can be improved, increasing the structural strength of the motor assembly 10. Thus, the use performance of the motor assembly 10 is more reliable to meet the use requirements, and the vehicle using the motor assembly 10 has higher use performance to meet the driving requirements of the user.
