A charging gun that can automatically fall off

Abstract

The invention discloses a charging gun with the automatic disengaging function. The charging gun comprises a charging gun body. An automatic disengaging device, an alarming device and a microprocessor are arranged in the charging gun body. The automatic disengaging device and the alarming device are connected with the microprocessor. The microprocessor is connected with the charging gun body. Through the automatic disengaging device and the alarming device, prompting and automatic disengaging can be achieved when a car owner drives a car away without pulling out the charging gun, and damages to the charging gun, and a charging cable and charging equipment connected with the charging gun are avoided. In the charging process, the automatic disengaging function is stopped, and the risks caused by power-on disengagement of a charging gun head are avoided. The charging gun disengagement function achieved through a miniature motor and a supporting rod is safer than that achieved through spring ejecting, and smooth disengagement of the charging gun can be better guaranteed. The detection result of a tension and pressure sensor is more precise compared with the situation that a mechanical structure is used for detecting the situation that the car owner drives the car away without taking down the gun head, and misjudgment caused by cable bending can be avoided.

Description

Technical field [0001] The invention belongs to the field of new energy, and particularly relates to a charging gun that can be automatically detached. Background technique [0002] With the promotion of new energy vehicles, electric vehicle charging equipment is playing an increasingly important role in people's lives. Because electric vehicles need to wait for a period of time to charge, some car owners still have bad operations such as forgetting to remove the charging gun from the charging port and then driving away after using the charging device to charge the electric car, causing the charging gun, charging cable and even charging A series of serious consequences such as equipment being damaged and equipment leakage. Although the charging gun has a certain anti-fall ability, it may still cause damage to the charging gun and affect the subsequent use due to the user's bad operation. It is still necessary to repair it after the charging gun head falls. Detection. [0003] Th...

Because electric vehicles need to wait for a period of time to charge, some car owners still forget to remove the charging gun from the charging port and drive away after using the charging equipment to charge the electric vehicle. A series of serious consequences such as equipment being pulled out, equipment leakage, etc.

Although the charging gun has a certain anti-drop ability, it may still cause damage to the charging gun if the charging gun falls to the ground due to bad operation by the user, affecting subsequent use. It is still necessary to repair the charging gun head after it falls detection

[0003] The current charging gun lacks a warning function, an emergency function when danger is about to appear, and a feedback function for user's bad operation
