Method for preventing charging gun from being locked

Abstract

The invention discloses a method for preventing a charging gun from being locked. The method for preventing the charging gun from being locked in a charging process comprises the following steps that when a user needs to charge an electric automobile, the user pulls out the charging gun, a charging pile detects the state of the charging gun, and when the charging gun breaks down or is damaged, the charging gun is locked on the charging pile, and characters are sent to an external panel of the charging pile; and after the user pulls out the charging gun and inserts the charging gun into the charging port of the electric automobile, the user presses an external lock hook to enable a clamping hook at the tail end of the lock hook to be clamped into the clamping groove in the charging port, and then the charging pile sends a pulse signal to an electromagnet. According to the method for preventing the charging gun from being locked, by arranging a fixing mechanism, a person cannot press the lock hook when a lock cylinder retreats, so the charging gun is prevented from being locked to a certain degree; and by arranging an anti-locking mechanism, the user can unlock the charging gun by himself or herself when the charging gun is locked, and therefore, the time of the user is prevented from being delayed, and the user has better use experience.

Description

technical field [0001] The invention relates to the technical field of charging guns, in particular to a method for preventing charging guns from being locked. Background technique [0002] Electric vehicles refer to vehicles powered by vehicle-mounted power supplies and driven by motors to drive wheels, which meet the requirements of road traffic and safety regulations. Because they have less impact on the environment than traditional vehicles, their prospects are widely optimistic. Electric vehicles are used for a long time Finally, it needs to be charged. At present, the charging gun is used to charge the electric vehicle. When the charging gun is charging, in order to prevent the charging gun from falling off, the charging gun is equipped with a locking device, which can be locked during charging to prevent the charging gun from falling off. [0003] Existing locking devices generally use electromagnets for locking. When charging, by pressing the external locking hook, t...
