Charging gun with safety alarm

Abstract

The invention relates to the technical field of strategic emerging industries, and discloses a charging gun with a safety alarm. The charging gun comprises a charging gun body and a charging connector. A charging wire and an alarm wire are connected in the charging gun main body; a positioning groove is formed in the bottom of the charging connector, and the charging head is fixedly connected to the left end of the charging gun body. A transition circuit is fixedly connected to the center of the top of the charging gun body, a stepped groove I is formed in one end of the top of the charging gun body, and a pressed block is movably connected into the stepped groove I in a sleeved mode. According to the invention, through the designed pressing block and lifting rod, a charging circuit can be switched on only after the charging gun is completely inserted into an automobile charging interface. When the automobile moves, the charging gun is not taken down, and a gap is formed between the charging gun and the automobile charging interface, the charging circuit is disconnected, so that the circuit is prevented from continuously outputting current, and short-circuit burnout and circuit faults of the automobile can be prevented.

Description

technical field [0001] The invention relates to the technical field of strategic emerging industries, in particular to a charging gun with a safety alarm. Background technique [0002] With the popularization of new energy vehicles, their charging equipment is also being laid vigorously, but the safety problems of charging equipment are also gradually increasing. [0003] Some car owners carelessly forget to remove the charging cable plugged into the charging port of the car before driving the car. If the car is still charging, the charging port of the car will rub against the charging cable during the movement of the car, which may cause serious damage. If a short circuit causes the charging equipment to burn out and the car has a circuit failure, even if the charging is completed, the car will tear off the charging gun during the movement, so that the wires on the charging gun will be exposed, and it is easy to cause electric shock to pedestrians passing by the charging pi...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing charging gun proposed in the background technology, the present invention provides a charging gun with a safety alarm, which has the functions of automatic power off, automatic alarm when pulled, and power off when the circuit is torn off. Advantages, it solves the problems in the above-mentioned background technology that the car starts when the charging gun is not removed, causing short circuit and car circuit failure, and the charging gun is torn off, causing motor damage and endangering public social safety.
