Self-circuit-breaking structure for automobile charging pile and circuit breaking method of self-circuit-breaking structure

Abstract

The invention discloses a self-circuit breaking structure for an automobile charging pile and a circuit breaking method thereof, the self-circuit breaking structure comprises a charging pile body, a charging gun is inserted in the front surface of the charging pile body, and the front surface and the back surface of the charging pile body are movably connected with transmission rods through pin shafts. A transmission motor drives a screw rod to rotate, the screw rod pushes a screw sleeve to move towards the left side through threads, the screw sleeve drives a sliding rod to slide in a transmission rod, the transmission rod is extruded and swings upwards with a pin shaft as the axis, and an extrusion rod located at the bottom of the transmission rod can pull a charging gun; and the charging gun is pulled to be separated from the charging pile body, so that the problems that an existing automobile charging pile is relatively single in structure and function, does not have the self-circuit-breaking effect after charging is completed, easily damages a vehicle battery in the continuous power supply process, and seriously affects the service life of the vehicle battery are solved.

Description

technical field [0001] The invention relates to the technical field of automobile charging piles, in particular to a self-breaking circuit structure for a car charging pile and a circuit breaking method thereof. Background technique [0002] The car charging pile is a device used to charge new energy vehicles, but the existing car charging pile has a single structure and function, and does not have the effect of self-disconnection after charging is completed. Damage to the vehicle battery seriously affects the service life of the vehicle battery. Contents of the invention [0003] In order to solve the problems raised in the above-mentioned background technology, the purpose of the present invention is to provide a self-breaking circuit structure and a circuit-breaking method for a car charging pile, which has the advantage of automatic circuit breaking, and solves the problem that the structure and function of the existing car charging pile are relatively single. It does...
