Abstract

The invention discloses an electric unlocking device for an automobile door lock. The electric unlocking device comprises a shell, a pawl assembly and a ratchet wheel, wherein the pawl assembly and the ratchet wheel are both installed inside the shell through rivets. The pawl assembly is provided with an unlocking driving mechanism for driving the pawl assembly to rotate around the rivets of the pawl assembly to separate a clamping part of the pawl assembly from the ratchet wheel, wherein the unlocking driving mechanism comprises a transmission gear, a transmission lug, a worm and an unlockingdriving motor for driving the transmission gear to rotate. The unlocking driving motor is fixed on the shell, the worm is connected with an output shaft of the unlocking driving motor, the worm meshes with the transmission gear, and the transmission lug is fixed on the surface of the transmission gear to toggle the pawl assembly to realize mutual separation between the clamping part of the pawl assembly and the ratchet wheel. According to the electric unlocking device, the unlocking and self-locking functions of the automobile door lock are realized, the reliability is high, the potential safety hazard is greatly reduced, the stability of the door lock is good, the service life is guaranteed, and the functions of shock resistance and noise reduction are achieved.
