Hub lock

Abstract

A hub lock comprises a fixing plate, a lock pin, a drive motor, a transmission mechanism and a hub claw. The lock pin is arranged on the fixing plate and rotationally connected with the fixing plate through a first rotation shaft. The drive motor is arranged on the fixing plate. The transmission mechanism is arranged on the fixing plate and connected with the drive motor and the lock pin. The hubclaw covers the fixing plate. The transmission mechanism is driven by the drive motor to drive the lock pin to rotate, and accordingly the lock pin is made to stretch in or retreat from the hub claw.The hub lock is arranged in a hub to be used, the hiding performance of the hub lock is high, and therefore violent damage for unlocking can be prevented, and the hub lock has very high safety. The hub lock has a dual locking structure, and when the hub lock conducts vehicle locking, the hub can be locked, and the purpose of safe vehicle locking is achieved. In addition, the risk of sudden stoppage during high-speed riding can be avoided through the hub lock, and by means of the hub lock, safety in the riding process can be improved.

Description

【Technical field】 [0001] The invention relates to a car lock, in particular to a wheel hub lock with high safety. 【Background technique】 [0002] In order to prevent vehicles such as bicycles, electric bicycles, and mopeds from being stolen, people usually use car locks to lock the cars. In daily life, the most common car lock is the horseshoe lock. The lock body of the horseshoe lock is usually ring-shaped, with an opening on it. When locking the car, the metal rod can be used to lock the opening of the lock body to prevent the rotation of the wheel hub, so as to achieve the effect of locking the car; Placed on the car body, it is very easy to be destroyed by violence. For example, a metal rod can be cut off by a tool to realize violent unlocking. Therefore, the safety of locking the car needs to be improved. [0003] Another common car lock is the expansion brake lock. The expansion brake lock uses the motor to hold the brake pads tightly to prevent the rotation of the ...

AI Technical Summary

Problems solved by technology

When this kind of brake lock is used repeatedly, its brake pads are easily worn out, resulting in insufficient reliability, which may cause lock failure and brake failure.

In addition, the brake pads rely on the brake pads to hold the tires tightly. It needs the drive motor to provide a high enough power to make the brake pads hold tightly. Therefore, it requires high motor power and high power requirements.

On the other hand, during high-speed riding, if the car is locked suddenly, this kind of brake lock will cause the car to stop suddenly, which has certain safety hazards

[0004] Therefore, the existing car locks either have insufficient car lock security, or their own security is not enough and may cause potential safety hazards, which all need to be improved.
