Electric vehicle charging gun locking device and installation assembly thereof

Abstract

The invention discloses an electric vehicle charging gun locking device and an installation assembly thereof. The electric vehicle charging gun locking device comprises an upper casing, a lower casing, a lock rod, an electric driving component, a transmission gear and a manual rotating rod, wherein the upper casing is fixedly connected with the lower casing, and the lock rod is in sliding fit withthe lower casing; a first perforation is formed in the lower casing, the protruding end of the lock rod faces the position of the first perforation, and the first perforation faces a lock rod perforation position on a charging socket; the lock rod is provided with a rack matched with the transmission gear, and the electric driving component drives the lock rod to extend or retract toward the perforation direction of the lock rod by means of the transmission gear; and the manual rotating rod comprises a rotating handle, a transmission rod and a gear. The electric vehicle charging gun locking device unlocks a charging gun in time when a charging gun electric locking device goes wrong, thereby ensuring the disassembly safety of the charging gun.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to a locking device for a charging gun of an electric vehicle and an installation assembly thereof. Background technique [0002] As one of the core components of the pure electric vehicle charging system, the charging socket is the center of the electric vehicle charging connection. Since the charging process of the power battery is easily disturbed by external factors, resulting in unexpected interruptions, it is necessary to set up an electronic lock for the charging socket. [0003] The charging socket is generally arranged at the LOGO part of the front face of the vehicle body or at the position of the fuel tank of the traditional car. During the charging process of the electric vehicle, due to the long charging time, it is easy to be bumped or interfered by external factors to cause charging interruption. It is equipped with an electronic lock device. It can...

Problems solved by technology

[0004] At present, a small number of pure electric vehicles are equipped with electronic lock devices, but the electronic locks in the prior art do not have a mechanical unlocking structure, and there is a certain risk when the charging gun is forcibly pulled out in the event of an accident with the electronic lock.

Because the electronic lock device in the prior art cannot realize the high-voltage interlock detection function at the connector position, although pr
