[0002] The car generator cover is an important part of the car generator (commonly called the alternator or generator). Its main function is to protect the components inside the generator and provide support for the normal operation of the generator.

[0003] For example, the automobile generator rear cover disclosed in authorization publication number CN214314827U includes a main body, a first boss disposed on the upper end surface of the main body, a through-hole disposed within the first boss, a first mounting portion disposed on the outer side of the first boss, and a first through-slot disposed on the main body. By adopting the above technical solution, the utility model has the following beneficial effects: a simple structure, convenient and quick processing, easy installation, long service life, excellent heat dissipation, and the ability to effectively prevent dust from entering the motor.

[0004] Although the above patent can effectively prevent dust from entering the motor, the contact area between the inner wall of the rear cover and the air is limited, which is not conducive to accelerating heat conduction, resulting in limited overall heat dissipation effect.
