Charging gun

Abstract

The invention discloses a charging gun suitable for a charging process for an electric vehicle or a hybrid electric vehicle. The charging gun comprises a gun shell, wherein the gun shell adopts an integrally-formed circular smooth transitional structure; the gun shell comprises a complete inner cavity; a charging assembly is fixedly arranged in the inner cavity; the charging assembly comprises a charging connector and a charging cable; an assembling cavity is arranged above the inner cavity; a locking plate and a gun upper cover are both connected with the gun shell through the assembling cavity; and a reset spring and a microswitch are also arranged in the assembling cavity. According to the charging gun, the waterproof performance of the charging gun is improved effectively; meanwhile, the overall structural strength of the charging gun is improved as well; due to water discharging holes, water drops permeated to the charging gun shell can be discharged smoothly, so that the service life of the charging gun is prolonged; and meanwhile, due to the microswitch, the locking and buckling process of the charging gun has a co-movement performance, so that the reliability of the charging gun in the use process is improved.

Description

technical field [0001] The invention relates to a charging gun, which is especially suitable for use in the charging process of electric vehicles or hybrid vehicles, and belongs to the field of charging equipment for new energy vehicles. Background technique [0002] With the continuous development of our society and the continuous improvement of our domestic economic level, our residents' awareness of environmental protection has gradually increased, and their demand for low-carbon life and low-carbon economy has become increasingly strong. At the same time, it is an indisputable fact that domestic and foreign oil prices continue to rise. Therefore, for the automotive industry, people are urgently seeking new engine technology to replace the traditional internal combustion engine technology. Under such a general environment, new energy vehicles such as electric vehicles or hybrid vehicles that meet people's expectations for energy conservation and environmental protection ...

AI Technical Summary

Problems solved by technology

Specifically, firstly, the shells of common charging guns are composed of splicing. Such a shell design makes the overall strength of the shell of the charging gun low and cannot withstand accidental rolling by vehicles. In addition, this splicing type The waterproof performance of the shell is also poor; second, the surface of the common charging gun shell is completely closed, once rainwater seeps into the shell along the seam of the charging gun, it is difficult to discharge, because there are many electrical components in the charging gun, so rainwater The existence of charging gun can easily cause short circuit and damage; third, although common charging guns are equipped with locking devices, they are basically locked from the shape and structure, and the entire locking process lacks linkage and cannot be done. To limit the opening and closing of the electrical path of the charging gun
