Electric children safety structure of automobile door lock

Abstract

The invention discloses an electric children safety structure of an automobile door lock, comprising a motor; the motor drives a worm and is connected with the worm; the worm is meshed with a worm gear; a first shaft is sleeved by the worm gear; the worm gear is provided with a first bulge matched with the first end of a pushing swing rod; a second shaft is sleeved by the pushing swing rod; the second end of the pushing swing rod is matched with a transitional rod; the transitional rod and an inward opening rod can slide mutually; the inward opening rod drives a handle inside an automobile and is connected with the handle inside the automobile; a third shaft is sleeved by the inward opening rod capable of overcoming a torsion of a second torsion spring and rotating around the axis of the third shaft; the motor drives the worm to rotate; the worm drives the worm gear to rotate; the first bulge on the worm gear toggles the pushing swing rod to rotate; and when the pushing swing rod drives the lower end of the traditional rod to be close to a plane where an opening connecting rod is located, an inward opening handle is pulled to drive the inward opening rod to overcome the torsion of the second torsion spring, so that the lower end of the transitional rod toggles the opening connecting rod to overcome a torsion of a first torsion spring to drive a pawl to rotate, and furthermore, the door lock is unlocked.

Description

technical field [0001] The invention relates to the technical field of automobile door locks, in particular to an electric child safety structure of an automobile door lock. Background technique [0002] With the rapid and diversified development of automobiles in various countries, the shape and internal layout of automobile side door systems are also very different.
