Full-automatic electric door lock for vehicle

Abstract

The invention relates to a fully automatic electro lock for vehicles, which comprises a ratchet, a motor and a drive system. The drive system comprises a pinion mounted on the output shaft of the motor; a driving part that is engaged with the pinion and drives. Another end of the driving part is provided with a first pressing part and a second pressing part; a first switch that matches with the first pressing part; a second switch that matches with the second pressing part; a force-applying arm that matches with the ratchet; a third switch detecting the position of the ratchet; a pawl limiting the ratchet to rotate toward the open position; an opening arm that is fixed with the pawl; a fourth switch that can detect whether the opening arm is at the initial state and can control the rotation of the motor; a swinging arm that can touch the lower end of the arc of the driving part, so that the rotation of the driving part can drive the swinging arm to swing, and another end of the swinging arm touches with another end of the opening arm. The drive system eliminates the shortcomings associated with a clutch, achieves the locking / unlocking of door lock through a single motor, so the invention is of advantages of the simple structure, the short process flow, the low manufacturing cost and the easy installation.

Description

A fully automatic car electric door lock technical field The invention belongs to the technical field of locks, in particular to a fully automatic electric door lock for automobiles. Background technique Existing electric door locks for automobiles, especially for electric locks on sliding doors of automobiles (such as vans), include electric control parts and mechanical parts, with central centralized control integration structure and split structure. There are two implementation schemes for the electric control part in the electric door lock. One is that the electric control part uses dual motors to realize the unlocking and locking of the door lock respectively. There are two installation methods for electric locks with dual motors. One is to install the two motors and the lock body together. The disadvantage is that the structure is complicated. A separate circuit must be designed inside the lock body to coordinate the connection between the two motors and the switch;...
