The most common charging port covers on the market are manual gooseneck or hinged types. This type of charging port cover needs to be opened manually. The opening process is simple and lacks aesthetics and occupies a large external space, which is easy to cause accidental damage. The use of LPP electronic locks or structural locks also increases the production cost of the charging port cover, and the vehicle cannot be opened when it is abnormally powered off. If it is not used, the charging port cover cannot be effectively fixed, and it can be easily opened from the outside when the car is locked, or violently opened, causing structural damage.

It can ensure that the charging port cover is not damaged when it is opened and closed abnormally. The synchronous gear transmission method ensures the uniform speed and stability of the opening process, and realizes automatic opening under the power provided by the actuator assembly, which improves the technological sense of the whole vehicle. The application of locking structure is reduced, and the cost is effectively reduced. At the same time, the utility model has a simple structure, compact size, excellent appearance, and has market promotion value.
