Safety locking device for electric vehicle charging gun

Abstract

The invention discloses a safety locking device for an electric vehicle charging gun. The safety locking device for the electric vehicle charging gun comprises a charging port sleeve, a locking hole formed in the charging port sleeve, a trigger protrusion arranged on a transition ring, a detecting switch arranged in the recess of a casing, a lock cylinder comprising a rack portion and a locking portion, and a drive motor. The power output shaft of the drive motor is coaxially provided with a gear, and the gear and the rack portion are engaged with each other; when a tip of the charging gun isinserted into the charging port sleeve and the triggering protrusion abuts against the detecting switch, a motor controller controls the drive motor to work, to drive the lock cylinder to slide alonga sliding seat towards the outer side of the casing to lock the tip to the charging port sleeve; and when a charging controller detects that a rechargeable battery is fully charged, the motor controller controls the drive motor to work, to drive the lock cylinder to slide along the sliding seat towards the inner side of the casing to unlock the tip from the charging port sleeve. By applying the safety locking device for the electric vehicle charging gun, the charging gun is arbitrarily removed during the charging process is avoided, and the rechargeable battery is protected.

Description

technical field The invention relates to the field of new energy vehicles. More specifically, the present invention relates to a safety locking device for a charging gun of an electric vehicle. Background technique New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. New energy vehicles can also be called electric vehicles, which need to charge the rechargeable battery from time to time. The charging place is similar to a gas station. There are charging piles set up in the charging place, and the electric vehicles are charged through the charging gun on the charging pile. However, the charging process is different from the refueling process. For several hours, therefore, the owner is often...
