Description

technical field [0001] The invention relates to the technical field of locking a refueling or charging door, in particular to a lock structure with a lock pin for a refueling or charging door. Background technique [0002] The small door for refueling or charging is an indispensable part of gasoline vehicles, electric vehicles and hybrid vehicles. However, up to now, most of the small doors are equipped with pull cables and opening handles in the car, or the actuator motor is used to drive the lock pin back, and the small door is bounced by a spring designed in the small door assembly for a certain distance, and then the small door is opened manually. door for refueling or charging. Traditional fuel vehicles need the anti-theft function of the fuel tank, while new energy vehicles such as electric vehicles do not need anti-theft. In order to reduce costs, some small doors of new energy vehicles only adopt the locking structure of pressing and popping open and closing, withou...
