A kind of faucet lock for car

Abstract

The invention provides a vehicle handlebar lock, and belongs to the technical field of vehicle locks. The vehicle handlebar lock solves the problem of poor reliability of a vehicle faucet lock in theprior art. The vehicle handlebar lock comprises a shell, wherein an installation cavity is formed in the shell. An installation plate body is fixedly arranged in the installation cavity. A lockpin sliding block is slidably arranged on one side surface of the installation plate body. A lockpin is connected to the lockpin sliding block, and the lockpin is enabled to extend out or retract into the shell through the back-and-forth sliding of the lockpin sliding block. The vehicle faucet lock further comprises a driving disk positioned on the side part of the lockpin sliding block and a driving structure capable of driving the driving disk to rotate in the circumferential direction. One side surface of the driving disk is opposite to the lockpin sliding block, and a spiral embedding groove is formed in the one side surface of the driving disk. One end of the embedding groove is close to the circle center of the driving disk, and the other end of the embedding groove is close to the edge ofthe driving disk, and a protrusion slidably embedded in the embedding groove is arranged on the lockpin sliding block. The vehicle handlebar lock has the advantage of high reliability.

Description

technical field [0001] The invention belongs to the technical field of vehicle locks, and relates to a vehicle faucet lock. Background technique [0002] Generally, motorcycles and battery cars are equipped with faucet locks. When the vehicle is parked, the faucet of the vehicle is killed, and the lock pin of the vehicle faucet lock extends out and enters the keyhole on the faucet to lock the direction of the faucet to lift Vehicle anti-theft performance. [0003] Car faucet locks all have retractable lock pins. The most traditional car faucet locks are purely mechanical, that is, using a key to turn the lock cylinder to realize the expansion and contraction of the lock pin. This structure is more troublesome to operate and lower in grade. Therefore, along with the development of science and technology, also there is the car faucet lock of remote control type on the market at present, as disclosed Chinese patent document (application number: 02227462.6; Authorization announ...

AI Technical Summary

Problems solved by technology

Such a structure has the following disadvantages: First, the anti-theft lock uses a cam structure to drive the lock pin to expand and contract, and there is only a conflicting relationship between the two. When the motor drives the cam to return, the control circuit detects that the motor is already in the reset state, but the lock The pin may still be in an incomplete or even unretracted state, causing the control circuit to misjudge the position of the lock pin, resulting in failure to unlock the faucet and reduced reliability; or the vehicle is driving in a state where the lock pin is not fully retracted. Cause abnormal noise or safety accidents; second, the expansion and contraction of the lock pin is controlled by the swing range of the cam, but the anti-theft lock completely relies on electronic control to limit the swing range of the cam, so the cam swing angle may be insufficient Or if the swing angle is too large, the amount of expansion and contraction of the lock pin is the same every time; third, because there is no structure to prevent the lock pin from protruding, the control circuit may malfunction during driving, causing the motor to drive The rotation of the cam makes the lock pin protrude abnormally, so that the faucet will be difficult to rotate or even locked, resulting in safety accidents

All of the above factors have caused the problem of poor reliability in the anti-theft lock.
