Charging gun structure of electric automobile

Abstract

The invention discloses a charging gun structure of an electric automobile. The structure comprises a charging gun head and a charging gun body, the charging gun head and the charging gun body are ofan integrated structure, and a charging plug is arranged on the right side of the charging gun head; a suction disc is arranged at the right end of the charging gun head, the suction disc is opened rightward, and a power adapter and a micro vacuum pump are arranged in the charging gun head; the power adapter is connected with a charging cable on the bottom of the charging gun body, the power adapter is further connected with the micro vacuum pump and the charging plug, and an air pumping port of the micro vacuum pump is formed in the charging gun head on the right side of the suction disc; anair exhaust port of the micro vacuum pump is formed in the charging gun head on the left side of the suction disc, a vacuum pump switch is arranged at the top of the charging gun head, and a chargingswitch is arranged on the left side of the charging gun head. The charging gun structure of the electric automobile is novel in design and simple in structure,the safe and stable charging process is guaranteed, and the service life of products is prolonged.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging equipment, in particular to a structure of an electric vehicle charging gun. Background technique [0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and conforming to the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, electric cars have become the development trend of future cars. [0003] The function of the electric vehicle charging pile is similar to that of the fuel dispenser in the gas station. It can be fixed on the ground or on the wall, and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential area parking lots or charging stations. The voltage levels charge various models of electric vehicles. [0004] The input end of the charging pile is directly connected to the...

Problems solved by technology

[0005] Most of the existing charging piles are installed in the open air, and the charging gun has no protective structure. When charging in rainy days, the charging plug is easily damaged during the process from picking up the charging gun to inserting the charging plug of the charging gun into the charging socket of the electric vehicle. Rainwater splashing will greatly reduce the safety of charging, and it is prone to failure, reducing the service life of the product. At the same time, when charging in rainy days, rainwater will flow into the charging socket along the outer wall of the car, which is prone to short-circuit failure or rusting of the charging plug and charging socket.

[0006] Furthermore, the connection between the charging plug of the charging gun and the charging socket of the electric vehicle is usually fixed with buckles. After a large number of uses, the interface will become loose and the connection will not be tight, and poor contact or even the charging gun will easily fall.
