Electric unlocking mechanism of side door lock of automobile

Abstract

The invention discloses an electric unlocking mechanism of a side door lock of an automobile. The electric unlocking mechanism comprises a pawl, a ratchet, an actuator and an electric motor. The pawl and the ratchet are rotatably positioned on an automobile door, the pawl is meshed with the ratchet, torsion for keeping the ratchet and the pawl facing meshed directions is exerted on the ratchet and the pawl respectively, a latch hook capable of being locked with a latch is arranged on the ratchet, the actuator can receive an unlocking instruction of a keyless entry system module of the automobile and can control the motor when the motor rotates, and the motor can drive the pawl to rotate. The electric unlocking mechanism has the advantages that signals are received by a key sensing device of the automobile and are transmitted to the actuator, and the actuator controls actions of the electric motor, so that the ratchet can be released from the pawl, an unlocking action is implemented, the automobile door is opened automatically without manually pulling a handle of the automobile door, and the electric unlocking mechanism is convenient to use and appears upscale and elegant.

Description
