Abstract
A vehicle-mounted burglar alarm comprises a vehicle-mounted remote control transmitter and a vehicle-mounted remote control receiver. A circuit formed by connecting a battery and a key hole, namely a vehicle ignition switch in series is arranged beside a circuit of the vehicle-mounted remote control receiver. The circuit formed by connecting the battery and the key hole in series is in series connection with a normally-closed manual switch and in parallel connection with a relay circuit. The relay circuit comprises an electromagnetic relay and a starting switch of the vehicle-mounted remote control receiver, and the preceding manual switch for controlling the whole circuit is in series connection with the circuit formed by connecting the battery and the key hole in series. A contact switch is installed near one end of the electromagnetic relay, is in series connection with the ignition switch, is provided with a spring and is under a normally-open state. The vehicle-mounted burglar alarm has the advantages that an automobile can be locked through the manual switch and the contact switch; the vehicle-mounted remote control receiver can still performance certain original functions such as warning; when a person gets off the automobile, a remote controller is not used, and interference of a decoder on the remote controller can be avoided; a thief can be prevented from picking a lock, and even if the ignition switch is closed, the automobile cannot be driven away.
Description
Technical field
The present invention relates to anti-theft device for vehicle, i.e. a kind of vehicle theft-proof device.
Background technology
No matter be that automobile or motor bike mostly use a teleswitch antitheft at present, when thief touches car body, remote controller can send sound automatic alarm, but this remote controller only can play the effect of warning, can not stop thief to open the key of car, sometimes also can produce wrong report, if any people, encounter because of carelessness car, remote controller also can be reported to the police; The remote controller of automobile can be locked or unblank the car door of automobile, but is easily subject to the interference of bad person's demoder, takeed on Door Lock, but reality is not locked.
Summary of the invention
In order to overcome remote controller, only can play the effect of warning and easily be subject to demoder interference shortcoming, the present invention has proposed a kind of new technical scheme of vehicle theft-proof device in conjunction with existing onboard remote controller.
This vehicle theft-proof device, comprise vehicle-mounted remote-control projector and vehicle-mounted remote-control receptor, it is characterized in that, by the circuit of vehicle-mounted remote-control receptor, there are battery and key hole, it is the circuit that automobile ignition switch is composed in series, a hand switch has been installed in series on this circuit, hand switch is normally closed switch, a relay circuit simultaneously in parallel, relay circuit comprises the starting switch of an electromagnetic relay and vehicle-mounted remote-control receptor, controlling the above-mentioned hand switch of whole circuit also connects wherein, near one end of electromagnetic relay, be equipped with a contact switch, contact switch is connected with ignition lock, on contact switch, be equipped with spring, for normally open.
While dispatching a car, first use the starting switch of the closed vehicle-mounted remote-control receptor of vehicle-mounted remote-control projector, electromagnetic relay work, contact switch is thereupon closed, and driver inserts car key again, and ignition lock is closed, and automobile can start; If first insert car key, the starting switch of rear closed vehicle-mounted remote-control receptor also can be by car engine.During parking, disconnect hand switch, the auto-closing of can do by myself thereupon, the starting switch of vehicle-mounted remote-control receptor has disconnected, contact switch is also pulled open by spring, driver extracts key, disconnect ignition lock, get final product relieved having left, vehicle-mounted remote-control receptor still can play some original effects such as warning.
Advantage of the present invention is, 1, can automobile is locked by hand switch and contact switch; 2, vehicle-mounted remote-control receptor still can play some original effects such as warning; While 3, getting off, do not use a teleswitch, can avoid the interference of demoder to remote controller; 4, can prevent thief's picking lock, although ignition lock closes, the starting switch of contact switch and vehicle-mounted remote-control receptor does not close, and automobile can not be driven away.
Accompanying drawing explanation
Fig. 1 is circuit diagram of the present invention
In figure: 1, vehicle-mounted remote-control projector, 2, vehicle-mounted remote-control receptor, 3, battery, 4, ignition lock, 5, hand switch, 6, electromagnetic relay, 7, the starting switch of vehicle-mounted remote-control receptor, 8, contact switch, 9, spring.
The specific embodiment
As follows to the detailed description of the invention below in conjunction with accompanying drawing:
This vehicle theft-proof device, comprise vehicle-mounted remote-control projector 1 and vehicle-mounted remote-control receptor 2, by the circuit of vehicle-mounted remote-control receptor 2, there are battery 3 and key hole, it is the circuit that automobile ignition switch 4 is composed in series, a hand switch 5 has been installed in series on this circuit, hand switch 5 is normally closed switch, a relay circuit simultaneously in parallel, relay circuit comprises the starting switch 7 of an electromagnetic relay 6 and vehicle-mounted remote-control receptor, controlling the above-mentioned hand switch 5 of whole circuit also connects wherein, near one end of electromagnetic relay 6, be equipped with a contact switch 8, contact switch 8 is connected with ignition lock 4, on contact switch 8, be equipped with spring 9, for normally open.
