Gear structure for head lock

Abstract

The invention discloses a gear structure for a head lock. The gear structure comprises a shell, wherein a locking shaft is disposed in the shell, the bottom end of the locking shaft extends out of thebottom wall of the shell, a motor bracket is fixed at the top of the shell, a variable speed motor and a control board are fixed in the motor bracket, a drive gear is fixed to a main shaft of the variable speed motor, a sliding block base is fixed at the top of the shell, a sliding block rack is arranged on the side face of the sliding block base, the sliding block rack is connected with the topend of the locking shaft, the sliding block rack is meshed with the driving gear, a limiting column is further fixed at the top of the shell, springs and Hall sensors are arranged at the top and the bottom of the limiting column, a limiting lug is arranged on the side wall of the limiting column, and the side part of the sliding block rack extends into the limiting column and abuts against the springs. According to the gear structure, the structure is reasonable in arrangement, the driving gear is driven by the driving motor, the sliding block rack are driven to ascend and descend, the springsare compressed, the stroke is controlled through the Hall sensors, the applicability is high, and the practicability is good.

Description

technical field [0001] The invention belongs to the technical field of motorcycle safety and anti-theft, and in particular relates to a gear structure for a front lock. Background technique [0002] In the motorcycle safety anti-theft system, the head lock is a relatively common anti-theft structure. The head lock in the prior art is mainly realized by a worm gear with a motor and a drive plate. Although it can achieve the purpose of anti-theft, its safety performance is relatively limited. Moreover, the stability is difficult to guarantee, so the applicability and practicality are limited. Contents of the invention [0003] The object of the present invention is to provide a gear structure for a head lock with reasonable structure and strong applicability. [0004] The technical solution to achieve the purpose of the present invention is a gear structure for head locks, including a housing, a locking shaft is arranged in the housing, and the bottom end of the locking sha...
