A car steering column electronic lock mechanism

Abstract

The invention discloses an electronic lock mechanism of an automobile steering column and relates to the field of motor vehicles. The electronic lock mechanism is characterized by comprising a plasticcover, an upper gear protection cover, a lower gear protection cover, a medium gear, a large gear, a motor socket, a motor gear, a spring bolt return spring, a motor, a spring bolt base, a spring bolt, a spring bolt safety limiting block, a locking body tubular column positioning seat, a locking limiting travel switch, anti-theft screws, a limiting block fixed correcting part, an unlocking limiting travel switch, a limiting block return spring, a PCB, a main body fixing base and a damping rubber plug. The electronic lock mechanism is reasonable in structure and easy to operate and cooperateswith a steering column below a steering wheel of an automobile, double guarantees in an unlocked state are achieved, the situation that the spring bolt accidentally falls due to only one guarantee andthus steering failure and an accident happen is avoided, and the purpose of integrating safety and functionality is achieved; moreover, when the unlocked state is changed into a locked state, the damping rubber plug can achieve buffering and damping effects on a jacking block at the bottom of the large gear so that not only can the collision noise caused by a return stroke be eliminated, but alsothe service life of the electronic lock mechanism can be better prolonged.

Description

technical field [0001] The invention belongs to the field of automobile steering systems, and in particular relates to an electronic lock mechanism of an automobile steering column. Background technique [0002] The working principle of the car steering lock is not complicated, but the car steering lock of some models on the market cannot be completely locked. Specifically, the user can still use a large force to realize the rotation. In this case, it is easy to make the ignition lock or other locks Parts are damaged. Contents of the invention [0003] In order to solve the above problems, the present invention aims to achieve it as follows: an electronic lock mechanism for the steering column of an automobile, which is characterized in that it includes a plastic cover, a gear protection upper cover, a gear protection lower cover, a medium gear, a large gear, and a motor socket , Motor gear, deadbolt return spring, motor, deadbolt base, deadbolt, deadbolt safety limit blo...
