Remote electric dragging-in mechanism of automobile door lock

Abstract

A remote electric dragging-in mechanism of an automobile door lock comprises a first connecting shaft, a second connecting shaft, a third connecting shaft, a fourth connecting shaft and a fifth connecting shaft, wherein a clamping plate is connected with the first connecting shaft in a rotating mode, a main locking jaw and an auxiliary locking jaw are connected with the second connecting shaft in a rotating mode, a dragging-in operating arm and a first torsion spring which controls the dragging-in operating arm to rotate are connected with the third connecting shaft in a rotating mode, the fourth connecting shaft is arranged at one end of the dragging-in operating arm, a remote dragging-in device stay wire is connected at the other end of the dragging-in operating arm, a driving arm is connected with the fourth connecting shaft in a rotating mode, a second torsion spring which controls the auxiliary locking jaw to rotate is connected with the fifth connecting shaft in a rotating mode, one side of the clamping plate is respectively contacted with the main locking jaw and the auxiliary locking jaw, and the driving arm is connected with the auxiliary locking jaw in a transmission mode. When the door lock is in a half-locked state, the remote electric dragging-in mechanism of the automobile door lock can effectively and conveniently achieve the fact that the door lock enters a full lock state safely and reliably. Meanwhile, in the electric dragging-in implementation process, an automobile door can be normally opened through an inner opening mechanism and an outer opening mechanism, and convenience and comfortableness of operation of automobile door locks are improved.

Description

technical field [0001] The invention relates to an automobile centrally controlled door lock, in particular to a remote electric pull-in mechanism of an automobile door lock. Background technique [0002] Automobile door locks generally adopt the engagement structure of clamping plate and stop pawl, and the reliable locking of the car door is realized through the cooperation of the clamping plate and the lock on the door column. The opening of the car door lock is to pull the inner / outer operating mechanism of the door lock to drive the inner / outer opening mechanism to move the stop claw, so that the stop claw moves from the state of engaging with the clamp to the release state, and the clamp is under the spring force of the clamp. Under the action of the lock, it is separated from the lock. The existing general car door lock needs a large enough external force to close the door when the door is open to overcome the door seal force and spring force to make the door lock int...

AI Technical Summary

Problems solved by technology

The closing operation of existing car door locks is laborious, noisy and unreliable, which is inconvenient to use and cannot adapt to the increasingly tense pace of life.
