Description

Intelligent self-service charging pile

Technical Field

The invention relates to the field of electric vehicle equipment, in particular to an intelligent self-service charging pile.

Background

Electric vehicles are increasingly popular as environmentally friendly energy vehicles, and currently, the electric vehicles can mainly include pure electric power as power and hybrid electric power and other energy sources. As an auxiliary facility of electric vehicles, charging piles are also gradually popularized in cities, highway service areas and other places.

The present stake of charging needs after the car stops, and the manual rifle that will charge is connected to the mouth that charges of vehicle on, then waits to charge the end, takes off the rifle that charges again. At present, the charging of an electric vehicle is a longer process, and sometimes, the situation that a driver directly starts the vehicle because the driver neglects that a charging gun is still inserted on the vehicle after the charging is finished occurs. In this case, both the vehicle and the charging pile itself may be damaged.

Disclosure of Invention

Aiming at the technical problem, the invention provides an intelligent self-service charging pile.

The technical scheme includes that the charging gun comprises a main body fixedly arranged on the ground surface, the main body is connected with the charging gun through a charging wire, the charging gun comprises a shell, a charging port is formed in the front end of the shell, a handle is arranged at the rear end of the shell, an outer frame is arranged on the periphery of the peripheral wall of the shell and comprises a front frame and a rear frame which are arranged in parallel, the front frame is close to one side of the charging port of the charging gun, and the rear frame is close to one side of the handle of the charging gun;
