Description

Vehicle charging flap locking device and vehicle Technical Field The application relates to the technical field of vehicles, in particular to a vehicle charging cover locking device and a vehicle. Background With the popularization of electric vehicles, safety and convenience of a vehicle charging port are increasingly receiving attention. The charging port cover is used as an important part for protecting the charging port from dust, rainwater and human damage, and the reliability and the anti-theft performance of the locking mechanism are important. At present, a common locking mode of a vehicle charging port cover in the market is a purely mechanical pressing type structure. Namely, the user can realize locking or unlocking by directly pressing a specific part of the cover plate. The scheme has the advantages that the scheme has obvious defects that the anti-theft capability is extremely weak, any person can open the charging port cover through pressing action without authorization, malicious damage or unauthorized access cannot be prevented, and obvious safety and privacy hidden hazards exist. In order to improve safety, convenience and grade, a part of vehicle models adopt a motor locking mode. That is, after the motor receives the control signal, the charging flap is kept at the closed position by the transmission mechanism. However, such schemes still suffer from the disadvantage that many motor locking mechanisms do not provide sufficient retention after power failure, even with a self-locking drive design, which has limited resistance to reverse drive. When the charging port cover is exposed to violent prying, the acting force can reversely drive the motor transmission system, so that the mechanism is unlocked accidentally, and the anti-theft reliability is insufficient. In addition, motors and associated drive mechanisms are often bulky, costly, and present a risk of failure due to mechanical wear. In view of this, a new technical solution is necessary to overcome the drawbacks of the prior art.
