Abstract
The utility model discloses a theft-proof device for motor traffic vehicles, which is formed by the method that an encoder outputs a coded signal to a cipher receiver, the cipher receiver sends the signal into a decoder to carry out decoding, and then the decoded signal controls a fuel and electricity cutting off device. The output end of the decoder is also connected with an electrical controlled lockset which controls a chamber cover of a power machine chamber; the decoder, the fuel and electricity cutting off device and the electric controlled lockset are arranged in the power machine chamber. The utility model has the advantages of safety, reliability, etc.
Description
The utility model relates to a kind of anti-joyride device, and what it was suitable for using energy drives has power cabin, the various automotives of Cang Gai.
Alarms and security systems for automobiles of the prior art, most volume, decoding techniques of digital integrated circuit of adopting are controlled oil-break, and breaker device impels engine to start, and has only coding and decoding to coincide, and engine could turn round.All oil-breaks, breaker device all rely on last in a close circuit open circuit point to start engine.The actv. way of closed this open circuit point is exactly a short circuit, it also is car thief's general way, alarms and security systems for automobiles uses the short circuit method to start engine in order to prevent, the open-ended control point of former igniting switch is moved to electromagnetic valve, high-tension coil, transistor ignitor etc. locate, or relays of these control oil-breaks, breaker device open circuit point " are shut " in housing together." anti-theft device for motor vehicles " of " zL922019126 utility patent " for example.But this open circuit point still exists, and not having in the world can be by the device of absolute " shutting ", and for the car thief who is familiar with the alarms and security systems for automobiles circuit, it is easy to do removing electromagnetic valve high-tension coil or transistor ignitor.Even the anti-joyride device that has is provided with " trap " circuit, after in a single day anti-joyride device is removed, can make a certain circuit open circuit or short circuit confuse the car thief, but after product appeared on the market, technology was disclosed, the car thief still can get rid of this " trap " circuit easily.
The purpose of this utility model be make a kind of can be with electric control lockset under lock and key with the Cang Gai of engine, could start the automotive anti-joyride device that engine and the cabin that turns on the power cover with the separable coder that identical password arranged.
The purpose of this utility model is achieved by the following technical solution: by the coder outupt coded signal to the password receptor, the password receptor is sent its signal into decoder and is deciphered, the automotive anti-joyride device of decoding back control oil-break power break device.Decoder output also connects an electric control lockset, the Cang Gai of electric control lockset control power cabin; Its decoder, oil-break power break device and electric control lockset are placed in the power cabin storehouse.It makes present car thief general-duty change robbers cars such as removing anti-joyride device and operates all at first and need just can carry out under the prerequisite of the Cang Gai of the machine of turning on the power, and the Cang Gai of engine is tightly locked by the electric control lockset of decoder control, and the startup of engine is handled by oil-break, the breaker device of decoder control, the coding equipment that does not have to coincide can't start, power cabin lid also can't be opened, even if it is also at one's wit's end that the car thief is familiar with the circuit of alarms and security systems for automobiles, automotive can not be started and drive away.
The utility model compared with prior art has advantages such as safe, reliable.
Description of drawings of the present utility model is as follows:
Fig. 1 is a structure block diagram of the present utility model.
Fig. 2 is schematic circuit diagram of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in further detail: as shown in Figure 1, when separable coder (1) forms such as (adopt outside wireless, the line) ultrasonic, grafting is sent password into password receptor (2), password receptor (2) with password in cockpit imports engine cabin (3) (heavy line square frame Fig. 1) into, be arranged on decoder (4) in the power cabin and convert electric power to after with the cryptogram decoding that coincide, it is closed or open electric control lockset (6) to remove to drive oil-break power break device (5).As shown in Figure 2, when the coder (1) of Fig. 2 docks with password receptor (2), the voltage of the storage battery of engine adds to the input end of DC voltage-stabilizing IC7805 by ignition lock 10 at this moment, the 5V power supply of its output is added to 18 pin of decoder IC, be added to 18 pin of coding IC1 simultaneously by 7 ends of password receptor (2), so coding IC1 work.The pulse cipher of its output inputs to 14 pin of decoder IC2 by the 17 pin output of IC1 through 8 ends of receptor (2).If password coincide, 17 pin of decoding IC2 will be exported high level, thereby trigger controllable silicon SCR 1, SCR2 conducting, and it is electric that K1 oil-break power break device (5) and K2 control electric control lockset (6) is got, thereby controlled the startup of engine and the unlatching of electric control lockset.Start engine like this, the Cang Gai of the machine that turns on the power is subjected to coder holder's control, makes the auto theft behavior obtain the actv. containment.
Claims (2)
1, a kind of by coder (1) outupt coded signal to password receptor (2), password receptor (2) is sent its signal into decoder (4) and is deciphered, the automotive anti-joyride device of decoding back control oil-break power break device (5), it is characterized in that: decoder (4) output also connects an electric control lockset (6), the Cang Gai of electric control lockset (6) control power cabin (3); Its decoder (4), oil-break power break device (5) and electric control lockset (6) are placed in power cabin (3) storehouse.
2, automotive anti-joyride device according to claim 1, it is characterized in that: electric control lockset (6) is made up of the K2 of controllable silicon SCR 2 and electric control lockset (6), decoder (4) output high level, controllable silicon SCR 2 conductings, the K2 of electric control lockset (6) gets electric, and the Cang Gai that starts engine cabin (3) opens.
