Charge gun locking system

Abstract

The invention provides a charging gun locking system. The charging gun locking system comprises a charging gun, an electromagnetic locking mechanism and an auxiliary locking mechanism. The electromagnetic locking mechanism is arranged on a charging plug of the charging gun, and the auxiliary locking mechanism is arranged on a vehicle plug interface adapted to the charging plug. The electromagneticlocking mechanism includes electromagnets, a normally closed micro switch and normally open reed switches. The electromagnets are arranged on the end face of the charging plug, the normally closed micro switches are used for controlling the working state of an electromagnet coil, and the normally open reed switches are disposed near the end surface and located on the side wall of the periphery ofthe charging plug. The auxiliary locking mechanism is disposed in a U-shaped mounting groove, the U-shaped mounting groove is arranged along the inner wall of the plug interface and perpendicular tothe bottom of the plug interface, and the auxiliary locking mechanism includes a spring, a slider and guide rails. The charging gun locking system has the beneficial effects that under the cooperationof the electromagnetic locking mechanism and the auxiliary locking mechanism, a secondary auxiliary locking function between the charging gun and the plug interface is provided while a charging gun locking function is provided, the situation that the charging gun is locked in the plug interface is facilitated, the charging plug of the charging gun can be prevented from loosening out from the pluginterface, and the situation that damage to the charging gun caused by the charging gun shaking in the plug interface is avoided.

Description

technical field [0001] The invention relates to the field of electric vehicle charging, in particular to a charging gun locking system. Background technique [0002] As one of the new energy vehicles, electric vehicles have the advantages of low pollution, low noise, energy saving, etc., and can replace traditional vehicles to solve the problems of energy shortage and environmental pollution. Electric vehicles are more and more widely used in daily life, and charging equipment such as charging guns used in conjunction with them have also developed rapidly. At present, the charging process of electric vehicles is also very simple. Park the car in the charging area of ​​the charging pile, pull out the gun from the charging pile and insert it into the charging port of the car for charging. After charging, plug the charging plug back into the charging pile. Since the charging gun has a large current passing through it during charging, the protection measures of the charging gun...

AI Technical Summary

Problems solved by technology

At present, the charging plug of electric vehicles is simply engaged when charging, so it is easy to loosen and slide out, which not only affects normal charging but also poses safety hazards

Some charging guns do not have a locking device, and some users will insert the charging gun repeatedly to confirm whether the charging gun is locked or not.
