[0002] The automotive industry is moving towards lightweighting to achieve goals such as energy conservation, emission reduction, and reduced exhaust emissions. Some functional components with large shell shapes and thick walls are produced by casting or die casting using lightweight alloy materials. Automotive generator end covers, such as front and rear covers, cover the generator and play a role in shock protection, heat dissipation, and dust prevention. However, existing end covers have problems such as difficulty in achieving both heat dissipation and dust prevention, simple structure, and easy defects in die casting, which urgently need to be improved.

It includes a generator cover body, with four protrusions fixedly provided at the outer end of the cover body. A first connecting pipe is fixedly connected inside each protrusion. The end of the first connecting pipe near the generator cover body penetrates the cover body and extends into its interior. A second connecting pipe is inserted into the end of each of the first connecting pipes away from the cover body. A connecting mechanism is provided at the outer end of the second connecting pipe to mount the second connecting pipe onto the outer end of the first connecting pipe. A filter screen is provided at the end of the second connecting pipe away from the generator cover body to prevent dust from entering the cover body.
