An electric vehicle charging gun

Abstract

The invention relates to an electric vehicle charging gun, comprising a gun body provided with an inner cavity, a plug, a locking member and a wire harness, wherein a clamping sleeve is inserted on the gun body in a sliding manner; the clamping sleeve and the gun body are fixedly connected in a sliding manner through at least one ball plunger; the wire harness is fixedly connected with the clamping sleeve, and one end of the wire harness is placed in the inner cavity and connected with the plug; the locking member is laterally rotatably mounted on the gun body; the gun body is provided with afirst spring, and the locking member rotates counterclockwise under the elastic force of the first spring; the gun body is provided with a sliding rod that slides up and down, the upper end of the sliding rod is provided with a connecting rod, the lower end of the connecting rod is hinged with the upper end of the sliding rod, the upper end of the connecting rod is provided with a straight groove,the right end of the locking member is provided with a hinge shaft, and the hinge shaft is arranged in the straight groove; a second spring is arranged on the gun body, and the sliding rod slides upward through the elastic force of the second spring; and the sliding rod is connected with the clamping sleeve. The electric vehicle charging gun in the invention can satisfy normal use when charging the vehicle and also can ensure that the charging gun is pulled off safely from the vehicle in case of emergency.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a charging gun for electric vehicles. Background technique [0002] Due to the constraints of technological development and the influence of external factors such as weather and charging environment, the charging process of electric vehicles is usually relatively slow. According to the average charging time, even if it is to reach 50% of the rated power, it usually takes 20 hours at the fastest. - about 30 minutes; and such a long waiting period can easily make drivers sleepy, or forget about the charging event itself and focus on other things; On-duty self-service operation, so there will be no staff to remind the charging situation in time or perform the operation of plugging and unplugging the charging gun. [0003] Therefore, based on the above situation, once the charging is completed or the charging time is over, or the driver encounters an emergency, it is very ...
