Abstract

The invention provides an antitheft alarm device of an automobile tire, and belongs to the technical field of automobiles. The invention solves the problems that the existing device is low in accuracy of a detecting signal, insufficient in reliability and affects the antitheft effect. The antitheft alarm device comprises a proximity switch sensor, an analog-digital converter, a controller and an alarm, wherein the proximity switch sensor is used for detecting the extension length of a shock-absorbing coil spring; the analog-digital converter is used for performing analog-digital conversion on the signal transported by the proximity switch sensor; the controller is used for processing and analyzing the signal transported by the analog-digital converter and outputting a control signal when judging that the tire is in the stolen state; the alarm is used for whistling and alarming according to the control signal transported by the controller; the proximity switch sensor is connected with the input end of the controller through the analog-digital converter; and the alarm is connected with the output end of the controller. The alarming device is simple in structure, safe and reliable, and can prevent the tires from being stolen.

Description

technical field [0001] The invention belongs to the technical field of automobiles and relates to an anti-theft alarm device for automobile tires. Background technique [0002] With the popularization of vehicles, automobile tires and wheel hubs, as a relatively high-value automotive product, have also attracted the attention of criminals. Theft of tires and wheel hubs occurs from time to time, which has brought great trouble to car owners. And at present, most vehicles do not have anti-theft measures specifically aimed at tires, which brings great potential safety hazards to car owners. And tire and wheel hub are as a kind of parts of high-speed movement, it is difficult to install anti-theft mechanism, even if anti-theft design is carried out to wheel hub structure, also may cause the decline of the intensity and the life-span of wheel hub. [0003] In view of the above-mentioned problems, the existing Chinese patent literature discloses a car tire anti-theft system [appl...
