Description

Technical Field

[0001] The present invention relates to an automotive component, specifically an aluminum cover plate for a new energy vehicle engine and a stamping method thereof. Background Art

[0002] The engine cover plate, also known as the hood, is made of rubber foam and aluminum foil materials. When reducing engine noise, it can simultaneously isolate the heat generated during engine operation, effectively protecting the paint on the surface of the hood and preventing aging.

[0003] As is well known, the engine operates in a high-temperature, high-pressure, flammable environment, and there are accidents such as explosion, combustion, or leakage due to overheating or accidental damage of components. This is especially dangerous for the engines of new energy vehicles. As mentioned above, the cover plate made of rubber foam and aluminum foil materials will isolate the heat generated during engine operation. Therefore, it is extremely easy to cause electric leakage and spontaneous combustion of new energy vehicles in hot summer.

[0004] Although the existing engine cover plates can achieve good heat preservation effects in winter, they are prone to spontaneous combustion accidents in summer due to the inability to dissipate heat. Summary of the Invention

[0021] Fiber ropes, the fiber ropes are wound on the rollers and connected with the elastic telescopic rod groups;

[0022] Wherein, the two rollers are respectively connected with the driving winding disc and the driven winding disc through transmission belts.
