Description

Technical Field

[0001] The invention relates to an electronic lock, and in particular to an electronic lock for a charging base and a charging base assembly comprising the electronic lock. Background Art

[0002] In the prior art, when the charging gun is mated with the charging base on the electric vehicle, the locking pin of the electronic lock installed on the charging base engages with the locking hole on the charging gun to lock the charging gun to the charging base to prevent the charging gun from accidentally separating from the charging base during charging of the electric vehicle.

[0003] In the prior art, electronic locks usually use motors to drive the locking pin to move between the locked position and the unlocked position. When the locking pin is moved to the locked position, the motor stops. However, the reverse force generated by the back electromotive force when the motor stops will drive the locking pin to move backward from the locked position for a distance (usually 0.5 mm), which will cause the locking pin to fail to reliably engage with the locking hole on the charging gun, which can easily cause the charging gun to accidentally disengage from the charging base, seriously affecting the safety of use.
