본 고안은 차량의 도난을 방지하기 위한 장치에 관한 것으로, 차량의 시동을 걸기 위하여 키이홀더에 특정치의 저항이 부착된 시동키이를 삽입하여야 시동이 걸리게 함으로써 차량의 도난을 방지할 수 있게 한 것이다.The present invention relates to a device for preventing theft of a vehicle, and to start the vehicle, it is possible to prevent theft of the vehicle by inserting a starter key having a specific value of resistance into a key holder.

일반적으로 차량의 시동을 걸 때에는 키이홀더에 시동키이를 삽입하여 돌리면 배터리의 전원이 점화코일을 거쳐 배전기를 통해 점화플러그에 걸려 엔진을 구동시킨다. 그래서 종래의 경우에 시동키이는 배터리의 전원을 도통시켜 엔진을 구동시켜 주는 역할을 하는데 차량절도범은 차량의 시동키이가 없더라도 키이홀더의 접점을 접속시켜 차량의 시동을 걸 수 있었다.In general, when starting the vehicle, insert the ignition key into the key holder and turn the battery to power the engine through the ignition coil and the ignition plug through the distributor. Thus, in the conventional case, the ignition key serves to drive the engine by conducting the power of the battery, but the vehicle thief could start the vehicle by connecting the contact of the key holder even without the ignition key of the vehicle.

본 고안은 상기와 같은 단점을 해결하기 위하여 시동키이가 키이홀더에 삽입되는 금속부에 저항체를 부착시킴으로 양단의 비교저항값에 의해 작동되는 비교기의 출력으로 시동이 걸리도록 한 것이다. 즉, 비교기의 입력양단의 전압이 같으면 구동되는 트랜지스터가 릴레이를 작동시켜 차량의 시동이 걸리는 것으로 첨부도면에 의거하여 구성을 살펴보면 다음과 같다.In order to solve the above disadvantages, the present invention attaches a resistor to the metal part into which the starter key is inserted into the key holder, so that the starter is started by the output of the comparator operated by the comparison resistance values at both ends. That is, when the voltage across the input of the comparator is the same, the driving transistor operates the relay to start the vehicle. The configuration according to the accompanying drawings is as follows.

차량의 시동을 걸기 위하여 키이홀더에 삽입되는 금속부(21)에 저항(R4)이 부착된 시동키이(20)와, 입력양단에 각각의 분배저항인 저항(Rl)(R2)과 저항(R3)(R4)이 동일할때 동일한 전압이 입력되어 로우신호가 출력되는 비교기(ICI)와, 저항(R4)이 부착된 시동키이(20)의 금속부(21)가 삽입되지 않을때 구동전원(Vcc)에 의해 비교기(ICI)의 하이(HIGH) 출력으로 도통되다가 시동키이(20)가 삽입되었을 경우에 비교기(ICI)의 로우(LOW)신호에 의해 구동되지 않는 트랜지스터(TR1)와, 상기 로우신호가 출력되는 비교기(ICI)와 구동이 중지되는 트랜지스터(TR1)에 의해 전원(Vcc)의 입력으로 도통되는 트랜지스터(TR2)와, 트랜지스터(TR2)의 구동으로 작동되어 배터리전원(BAT) 을 도통시켜 점화코일(50)을 통해 엔진을 구동시키는 릴레이(RL)를 구비시켰다.A start key 20 having a resistor R4 attached to the metal part 21 inserted into the key holder to start the vehicle, and resistors Rl (R2) and resistors R3 which are respective distribution resistors at both ends of the input. When R4 is the same, when the same voltage is inputted and the low signal is output, the comparator ICI and the metal part 21 of the starter key 20 to which the resistor R4 is attached are not inserted. Transistor TR1, which is connected to the high output of the comparator ICI by Vcc and is not driven by the low signal of the comparator ICI when the ignition key 20 is inserted, The transistor TR2 is connected to the input of the power supply Vcc by the comparator ICI, from which the signal is output, and the transistor TR1 is stopped, and is driven by the drive of the transistor TR2 to conduct the battery power supply BAT. And a relay RL for driving the engine through the ignition coil 50.

이하, 저항(R4)이 내장원 시동키이(20)로 차량의 시동을 걸 수 있는 본 고안의 작용 및 효과를 상세히 설명하면 다음과 같다.Hereinafter, the operation and effect of the present invention to start the vehicle with the resistor R4 with the built-in one start key 20 will be described in detail.

제 1 도는 본 고안에 따른 시동키이(20)의 구성도로 시동키이(20)의 금속부(21)에 저항(R4)을 삽입시켜 부착된 것으로 시동키이(20)를 키이홀더에 삽입하여 저항값이 일치되어야 시동을 걸 수 있다. 또한, 저항값은 수Ω에서 수백MΩ까지 광범위하게 선택할 수 있으므로 비밀보장이 가능하다.1 is a block diagram of the starter key 20 according to the present invention, which is attached by inserting a resistor R4 into the metal part 21 of the starter key 20 and inserting the starter key 20 into the key holder. You must match this to start. In addition, resistance values can be selected from a few ohms to hundreds of MΩ to ensure confidentiality.

제 2 도는 시동키이(20)를 키이홀더에 삽입하였을 시에 시동키이(20)의 금속부(진)에 부착된 저항(R4)이 동일치의 저항(R3)과 접속되어 비교기(ICI)의-단자에 연결된다. 시동키이(20)를 꽂지 않거나 다른 시동키이를 사용하게 되면 비교기(ICI)의 양단전압이 서로 다르므로 비교기(ICI)의 출력전압이 하이상태가 되어 트렌지스터(TR1)가 구동된다. 따라서 트랜지스터(TR1)의 컬렉터측 출력이 로우로 되어 트랜지스터(TR2)가 구동되지않아 릴레이(RL)가 작동되지 않는다. 그러므로 점화코일(50)에 배터리 전원(BAT)이 공급되지 않아 엔진의 시동을 걸 수가 없다.2 shows that when the starter key 20 is inserted into the key holder, the resistor R4 attached to the metal part of the starter key 20 is connected to the resistor R3 of the same value so that the comparator ICI is connected. Is connected to the terminal. When the starter key 20 is not plugged in or another starter key is used, since the voltages at both ends of the comparator ICI are different from each other, the output voltage of the comparator ICI becomes high and the transistor TR1 is driven. Therefore, the collector-side output of the transistor TR1 goes low and the transistor TR2 is not driven so that the relay RL does not operate. Therefore, since the battery power BAT is not supplied to the ignition coil 50, the engine cannot be started.

한편, 규격에 적합한 저항값을 가는 시동키이(20)가 키이홀더에 삽입되면 각각의 저항값에 의하여 비교기(ICI)의 입력 양단 전압이 동일하게 된다. 따라서 비교기(ICI)의 입력 양단전압이 동일하게 된다. 따라서 비교기(ICI)의 출력 전압은 로우상태가 되고 트랜지스터(TR1)가 구동되지 않는다. 또한, 트랜지스터(TR1)의 컬렉터측 출력이 하이상태이므로 트랜지스터(TR2)는 구동된다. 그러므로 트랜지스터(TR2)의 구동은 릴레이(RL)를 작동시켜 배터리전원(BAT)을 점화코일(50)로 공급시켜 엔진의 시동을 걸게된다.On the other hand, when the starter key 20 having a resistance value conforming to the standard is inserted into the key holder, the voltage across the input of the comparator ICI is equal to each resistance value. Therefore, the voltage across the input of the comparator ICI becomes the same. Therefore, the output voltage of the comparator ICI becomes low and the transistor TR1 is not driven. In addition, since the collector-side output of the transistor TR1 is high, the transistor TR2 is driven. Therefore, the driving of the transistor TR2 operates the relay RL to supply the battery power BAT to the ignition coil 50 to start the engine.

본 고안은 상기와 같이 시동키이(20)에 삽입된 저항(R4)값에 의하여 비교기(ICI) 및 트랜지스터(TRl)(TR2)의 구동과릴레이(RL)의 작동으로 차량의 시동이 가능한 것으로, 마이콤(MICOM)의 제어없이 간단한 회로구성으로도 가능하며 시동키이(20)의 금속부(21)에 장착되는 저항(R4)의 선택범위가 매우 다양함으로 비밀보장이 가능하고 차량의 도난을 미연에 방지할 수 있어 차량 운용에 폭넓은 편의를 제공하는 것이다.According to the present invention, the vehicle can be started by the operation of the drive and the relay RL of the comparator ICI and the transistor TR1 TR2 by the resistance R4 inserted into the starter key 20 as described above. A simple circuit configuration is possible without the control of MICOM, and the range of selection of the resistor R4 mounted on the metal part 21 of the starter key 20 is varied so that it is possible to provide confidentiality and prevent theft of the vehicle. It can be prevented to provide a wide range of convenience for vehicle operation.
