Description

Technical Field

[0001] This utility model belongs to the field of electric vehicle technology. Specifically, this utility model relates to a protection structure for a drive motor in automobiles and a drive motor in automobiles. Background Technology

[0002] The breather, also known as a ventilator or gas exchange device, is an important component in electric vehicles. It is mainly used to manage the air circulation between the battery pack and the vehicle interior, effectively improving the overall performance and safety of the electric vehicle. In the current technology, most of the drive motor structure and the breather lack protective structures. During vehicle operation, water and mud can easily splash onto the breather and the connection points of the drive motor wiring harness, which can easily lead to water entering the motor or mud clogging the breather, preventing the drive motor from breathing and causing malfunctions. This affects driving safety and increases the cost of vehicle maintenance.

[0003] To address the aforementioned problems, patent document 206542277U discloses a generator cover and a motor vehicle alternator including the cover. The generator cover is connected to the motor vehicle alternator. The generator includes a front cover, a rear cover, and a motor shaft. The motor shaft is mounted and supported on the front cover and the rear cover. The generator cover is connected to the outside of the rear cover. The generator cover includes a radial wall, an axial wall, and multiple protrusions. The radial wall extends radially along the motor shaft; the axial wall extends axially along the motor shaft to the outside of the rear cover; and the multiple protrusions extend from the radial wall and / or the axial wall toward the rear cover. However, this design fails to solve the aforementioned problems. Utility Model Content
