Abstract
The invention discloses an anti-theft system for an automobile tire, which comprises at least one travel switch which is fixed on a chassis suspension, a body control module (BCM) and an alarm system. The travel switch can detect the motion condition of a swinging arm which is connected with the tire relative to the chassis suspension. The travel switch is disconnected in a normal state. When the distance of the swinging arm relative to the chassis suspension exceeds a set dimension, the travel switch transmits an electric signal to the body control module (BCM). The body control module (BCM) drives the alarm system to alarm, so wheels can be prevented from being stolen effectively.
Description
Technical field
The present invention relates to Vehicle Anti-Theft System, particularly the anti-theft system of motor tire.
Background technology
Stolen car parts case incidence of cases height, the detection difficulty big, can not obtain an indemnity even gone up full vehicle insurance yet.The robber is robbed the vehicle case constantly strengthen the detection dynamics along with national sector, burglar's stolen car difficulty of selling is sharply increased.But burglar's sight has been kept a close watch on easier auto parts and components of selling in recent years, and popular aluminium alloy wheel hub tire becomes burglar's target at present.The wheel hub tire of a general car is generally at 1,000 yuan, the burglar dismantles the tire of a car can be above 15 minutes, two people and many people commit a crime in the majority, and the burglar generally with utility van, three-wheel vehicle as means of delivery, can commit a crime a lot of one evening, booty is sold easily, and national sector is very big to the detection difficulty of this type of case.
Stolen in order to prevent wheel, existing settling mode mostly is and uses the motor tire anti-theft screw, its antitheft principle of anti-theft screw is exactly that sharp processing with anti-theft screw becomes fitfull external diameter shape, must use the supporting removal tool special of this wheel wheel could be pulled down.Allowing the burglar hold common withdrawing device can't set about.Though anti-theft screw can prevent to a certain extent that tire is stolen, tooling cost is higher, and at present a lot of vehicle is not equipped with anti-theft screw, and special instrument is easy to obscure and lose, and causing can't changing of tire, and risk is very big; The most important thing is that the instrument that can dismantle anti-theft screw at present is also more and more, can't fundamentally avoid tire stolen.
Summary of the invention
Technical matters to be solved by this invention is, has overcome the above-mentioned defective that the antitheft mode of existing tire exists, and a kind of automobile tire anti-theft system is provided, and fundamentally avoids the stolen problem of tire.
The technical solution adopted for the present invention to solve the technical problems provides a kind of automobile tire anti-theft system, comprise that at least one is fixed on travel switch, Body control module (BCM) and warning on the suspension of chassis, travel switch can detect the motion conditions of the relative chassis of the swing arm suspension that connects tire, during the travel switch normal condition, be open circuited, when the distance of the relative chassis of swing arm suspension surpasses the setting size, travel switch transmits the electrical signal to Body control module (BCM), and Body control module (BCM) drives warning and reports to the police.
Each connects the travel switch of all having installed on the cooresponding chassis of the swing arm suspension of tire, and when arbitrary travel switch transmits the electrical signal to Body control module (BCM), Body control module (BCM) drives warning and reports to the police.
Be provided with the travel switch contact block that cooperates with travel switch in the swing arm.
Anti-theft system could normal operation when car load is set up defences, detect the order of setting up defences of remote-control key when Body control module (BCM) after, Body control module (BCM) is just handled the signal that travel switch sends.
Warning is loudspeaker.
Stolen and Body control module receives that Body control module will drive the loudspeaker buzzing when remote-control key is separated anti-signal at tire.
The electric signal that travel switch sends is a low level signal.
Automobile tire anti-theft system of the present invention is based on existing simple Circuits System and machine design and the automobile tire anti-theft system realized.Travel switch can detect the motion conditions of the relative chassis of the swing arm suspension that connects tire.Steal the tire person when stealing tire, must be at first with chassis jack-up, in this process, when the distance of the relative chassis of swing arm suspension surpassed the setting size, Body control module (BCM) detected low level signal, activates anti-theft alarm.
Travel switch is fixed on the suspension of chassis, and during normal condition, this switch is open circuited; For better fit and clamping stroke switch, in swing arm, increased a travel switch contact block.Native system could normal operation when car load is set up defences.Detect the order of setting up defences of remote-control key when the vehicle body anti-theft module after, Body control module (BCM) is just handled the travel switch signal, when the distance of the relative chassis of the swing arm suspension that detect to connect tire reaches travel switch and compresses, travel switch sends low level signal to Body control module (BCM), Body control module (BCM) drives anti-theft loudspeaker and reports to the police, the car load anti-theft alarm is activated, and the robber just escapes on hearing the news, and is stolen thereby actv. prevents wheel.Simultaneously, for prevent because of tire stolen, chaufeur is not known that tire is stolen and after starting car bigger danger is taken place, when stolen and car load is separated anti-(Body control module receive remote-control key separate anti-signal) at tire, Body control module will drive 20 seconds of anti-theft loudspeaker buzzing, remind the chaufeur vehicle because of lacking very danger of tire.
Advantage of the present invention: 1, compare with traditional anti-theft screw, the present invention need not to be equipped with special withdrawing device, reduced because of chaufeur and lost the risk that instrument can't own changing of tire; 2, the travel switch that assembles on the car of the present invention, accuracy of detection is very high, has improved the real-time that detects, and simultaneously, expense is less; 3, the present invention is easy for installation, and it is little to implement difficulty, is convenient to promote; 4, the travel switch installation site is hidden among the present invention, can effectively prolong the service life of switch, and actv. prevents that the robber from destroying; 5, among the present invention, stolen and car load is separated when anti-at tire, and anti-theft loudspeaker buzzing 20S, actv. have avoided chaufeur because of lacking the bigger danger that tire startup automobile brings.
Description of drawings
Fig. 1 is an automobile tire anti-theft system Organization Chart of the present invention;
Fig. 2 is a travel switch of the present invention installation site scheme drawing.
Mark among the figure: 1, travel switch contact block; 2, travel switch.
The specific embodiment
To shown in Figure 2, automobile tire anti-theft system of the present invention is made up of four travel switches 2, four travel switch contact blocks 1, Body control module (BCM), an anti-theft loudspeaker as Fig. 1.When car load is set up defences; after Body control module (BCM) detects the order of setting up defences of remote-control key; Body control module (BCM) is just handled the travel switch signal; when the distance of the relative chassis of the swing arm suspension that detect to connect tire reaches travel switch and compresses; travel switch sends low level signal to Body control module (BCM); Body control module (BCM) drives anti-theft loudspeaker and reports to the police, and plays the purpose of effective protection motor tire.
Travel switch is positioned on the suspension of chassis suspension and the about 30mm of swing arm intersection, and contact block is positioned in the swing arm directly over the travel switch, can guarantee fully to cooperate closely with travel switch, guarantees the stability of signal.
