Abstract

The anti-theft device is installed in one vehicle body, which has rotating wheel shaft and at least one wheel with one defined air storing space. The anti-theft device has one controlled wheel deflating unit and one main control unit. The controlled wheel deflating unit has one air controlling assembly connected to the wheel and capable of being driven to switch from air maintaining state to air deflating state. The main control unit mounted on the vehicle body includes one main control circuit capable of sensing the motion of vehicle body to drive the air controlling assembly. In case of stolen vehicle, the air inside the wheel will be deflated and the vehicle can not be run.

Description

technical field [0001] The invention relates to an anti-theft device, in particular to an anti-theft device for vehicles. Background technique [0002] In the past, anti-theft devices for vehicles were installed to prevent vehicles from being stolen. Although there are many anti-theft devices on the market to prevent cars and motorcycles from being stolen, incidents of theft are still emerging. The key point is After the thief steals the car, he can quickly move the car body away from the scene and drive freely, which makes the search difficult. Contents of the invention [0003] The object of the present invention is to provide a kind of anti-theft device which makes it difficult for thieves to move the car body by deflated wheels to achieve anti-theft effect. [0004] The anti-theft device of the present invention is suitable for being installed on a car body, and this car body comprises a rotatable wheel shaft, and at least one wheel that can be co-rotatably installed ...
