Electric vehicle and charging socket thereof, and electronic lock used for charging socket

Abstract

The invention relates to an electric vehicle and a charging socket thereof, and an electronic lock used for the charging socket. An electric vehicle includes a charging socket, the charging socket includes an electronic lock, An electronic lock comprises a housing and an actuating mechanism, The output end of the actuating mechanism is connected with a lock pin, the electronic lock further comprises a manual unlocking mechanism, the manual unlocking mechanism comprises a dialing member, the dialing member is guided and movably assembled in the housing, a pulling rope is connected with the dialing member, a stopper is arranged on the lock pin, the dialing member is matched with the stopper in the retracting direction of the lock pin, and the manual unlocking mechanism further comprises a return spring. When the manual unlocking mechanism of the electronic lock is used, By pulling the toggle by pulling the rope, The retracting direction of the locking pin of the dialing member is matchedwith the stopper stop on the locking pin, thereby pulling the locking pin to retract and realizing manual unlocking. The unlocking pulling rope relies on the return spring and does not need to be driven by the actuating mechanism, so that the load on the actuating mechanism is not caused, the failure rate of the actuating mechanism is reduced, and the electronic lock is safer when being used.

Description

technical field [0001] The invention relates to an electric vehicle and its charging socket, and an electronic lock used in the charging socket. Background technique [0002] When charging an electric vehicle, it is necessary to insert the charging gun with the cable into the charging socket installed on the electric vehicle, and then turn on the power supply after it is plugged in place to realize charging. After charging, pull out the charging gun from the charging socket That's it. In order to prevent safety accidents caused by the charging gun being pulled out by mistake during the charging process, a locking device needs to be provided between the charging socket and the charging gun. At present, an electronic lock is generally installed on the charging socket, and the lock pin of the electronic lock is electrically controlled to be inserted into and disengaged from the keyhole on the charging gun to realize the locking and unlocking of the charging gun and the chargin...

Problems solved by technology

[0003] At present, the common manual unlocking mechanism on the market is to fix the pull cord on the lock pin, and pull the lock pin to unlock through the pull cord, and the reset after the lock pin is unlocked or the locking action of the lock pin will drive the pull cord to move synchronously, and There is generally a sealing structure between the existing pull cord and the casing for sealing, so the friction between the pull rope and the casing is relatively large. When manually unlocking, the pull rope can still be pulled by relying on the pulling force of the hand, but when the lock pin is locked During the normal locking and unlocking process, and during the return process of the lock pin after the lock pin is manually pulled to unlock under abnormal circumstances, if the pull rope is pulled by the action mechanism, it will inevitably cause a greater burden on the action mechanism, and even cause the action mechanism to fail. The situation of the action, which will cause the lock pin of the electronic lock to not work normally
