도 1 및 도 2 에 도시된 바와같이, 본 발명은 자동차 키(10)의 삽입부(11a)에 천공홀(11H)이 형성되고, 상기 키(10)의 삽입부(11a)가 삽입되는 키홀(22a)이 형성된 키홀바디(22) 및 상기 키홀바디(22)를 회동가능하게 내재하는 실린더하우징(21)에 상기 키(10)의 언록조작시 상기 천공홀(11H)과 위치형합되어 연통되는 다수의 관통공(21Ha,21Hb,22Ha,22Hb)이 형성되고, 상기 관통공(21Ha,21Hb,22Ha,22Hb) 및 상기 천공홀(11H)을 통해 투과된 빛을 감지하도록 상기 실린더하우징(21)의 양측벽에 설치되는 발광부(PD) 및 수광부(PTR)가 구비되어 이루어지는 차량용 도난방지장치에 있어서, 상기 수광부(PTR)의 신호를 반전하는 인버터(G1)와, 상기 인버터(G1)의 출력신호와 상기 키(10)의 언록조작신호를 논리곱출력하는 앤드게이트회로(G2)와, 상기 앤드게이트회로(G2)의 출력신호에 따라 점화스위치로(S1)로부터 점화코일(L1)로 인가되는 전원전류를 차단하는 점화차단부(60)와, 상기 앤드게이트회로(G2)의 출력신호에 따라 운전자가 휴대한 수신기(72)로 도난신호를 발신하도록 차체에 설치된 송신기(71)를 구동시키는 송신기구동부(71)로 구성되는 특징이 있다.As shown in FIG. 1 and FIG. 2, in the present invention, a perforation hole 11H is formed in the insertion portion 11a of the automobile key 10, and a key hole into which the insertion portion 11a of the key 10 is inserted. A keyhole body 22 having a 22a formed therein and a cylinder housing 21 in which the keyhole body 22 is rotatably embedded are in communication with the punched hole 11H when the key 10 is unlocked. A plurality of through holes 21Ha, 21Hb, 22Ha, 22Hb are formed, and the cylinder housing 21 to detect light transmitted through the through holes 21Ha, 21Hb, 22Ha, 22Hb and the drilling hole 11H. In the anti-theft device for a vehicle provided with the light emitting part PD and the light receiving part PTR which are provided in the both side walls of the WHEREIN, Inverter G1 which inverts the signal of the light receiving part PTR, and the output of the said inverter G1. The AND gate circuit G2 for logically outputting the signal and the unlock operation signal of the key 10, and the ignition type according to the output signal of the AND gate circuit G2. The ignition cut-off unit 60 which cuts off the power current applied from the chiro S1 to the ignition coil L1 and the receiver 72 carried by the driver in accordance with the output signal of the AND gate circuit G2 transmit the theft signal. It is characterized by consisting of a transmitter driving unit 71 for driving the transmitter 71 installed in the vehicle body to transmit.

상기 점화차단부(60)는 상기 앤드게이트회로(G2)의 출력단에 에미터접지의 트랜지스터(TR1)의 베이스가 접속되고, 상기 트랜지스터(TR1)의 컬렉터에 코일(RYa)이 접속되는 릴레이의 가동접점(RYb)의 양단을 점화스위치(S1)와 접화코일(L1)의 사이에 접속하여서 된다.The ignition cut-off unit 60 is connected to the output terminal of the AND gate circuit G2, and the base of the transistor TR1 of the emitter ground is connected, and the coil RYa is connected to the collector of the transistor TR1. Both ends of the contact RYb may be connected between the ignition switch S1 and the contact coil L1.

상기 송신기구동부(70)는 상기 앤드게이트회로(G2)의 출력단에 에미터접지의 트랜지스터(TR2)의 베이스가 접속되어, 상기 앤드게이트(G2)의 출력신호에 따라 컬렉터에 인가된 전원전류를 통전하여 상기 송신기(71)의 송신신호로 동기하도록 구성된다.The transmitter driver 70 has a base of the transistor TR2 of the emitter ground connected to the output terminal of the AND gate circuit G2, and energizes the power current applied to the collector according to the output signal of the AND gate G2. To synchronize with the transmission signal of the transmitter (71).

상기 점화차단부(60)의 릴레이(RY)는 코일(RYa)의 여자시에 가동접점(RYb)이 오프되는 것이고, 상기 점화스위치(S1)는 운전석에 설치되는 통상적인 스위치이고, 상기 점화코일(L10은 엔진의 점화플러그로 고압의 전류를 제공하는 통상적인 것이다.The relay RY of the ignition cut-off unit 60 is one in which the movable contact RYb is turned off when the coil RYa is excited, and the ignition switch S1 is a conventional switch installed in the driver's seat, and the ignition coil (L10 is a conventional one that provides high voltage current to the spark plug of the engine.

이와같이 구성된 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

먼저, 침입자가 임의의 천공홀(11H)이 형성된 키(10)의 삽입부(11)를 키홀(22a)에 삽입하여 언록조작할 때 키고유코드가 일치하지 않아 발광부(PD)에서 조사된 빛이 관통공(21Ha,21HB,22Ha,22Hb)과 천공홀(11H)을 통해 수광부(PTR)에 이르지 않게 되면, 상기 수광부(PTR)에서는 로우레벨의 신호를 출력하게 되고, 이 신호는 인버터(G1)를 통하면서 반전되어 하이레벨의 신호로 앤드게이트회로(G2)의 일입력단에 인가된다. 한편, 상기 앤드게이트회로(G2)의 타입력단에는 키의 언록조작으로 인한 하이레벨의 신호가 입력되는데, 이러한 두 신호를 논리곱하는 앤드게이트회로(G2)의 출력신호는 하이레벨의 신호로 점화차단부(60)의 트랜지스터를 턴온시키게 된다. 이에 따라 트랜지스터(TR1)는 릴레이(RY)의 코일(RYa)을 자화하여 가동접점(RYb)을 오프시키게 되므로 침입자가 엔진시동을 위해 점화스위치(S1)를 켜도 점화코일(L1_로는 전원이 인가되지 않게 되므로 엔진시동은 불가하게 된다.First, when the intruder inserts the insertion portion 11 of the key 10 having the arbitrary hole 11H formed therein into the key hole 22a and the unlock operation is performed, the key inherent codes do not coincide. When the light does not reach the light receiving portion PTR through the through holes 21Ha, 21HB, 22Ha, 22Hb and the drilling hole 11H, the light receiving portion PTR outputs a low level signal, and the signal is an inverter ( It is inverted through G1) and applied to one input terminal of the AND gate circuit G2 as a high level signal. On the other hand, a high level signal is input to the type force terminal of the AND gate circuit G2 due to the unlock operation of a key, and the output signal of the AND gate circuit G2 that logically multiplies these two signals is a high level signal to shut off the ignition. The transistor of the unit 60 is turned on. Accordingly, the transistor TR1 magnetizes the coil RYa of the relay RY to turn off the movable contact RYb. Therefore, even if an intruder turns on the ignition switch S1 to start the engine, power is supplied to the ignition coil L1_. The engine can not be started.

또한, 본 고안은 상기한 바와같이, 점화차단부(60)를 구동시켜 점화코일(L1)로 공급되는 전원을 차단하는 동시에 송신기구동부(70)의 트랜지스터(TR1)를 턴온시켜 차체에 설치된 송신기(71)에서 송신신호를 발신하도록 동기신호를 부여하게 되므로 운전자가 휴대한 수신기(72)는 상기 송신기(71)의 발신신호를 수신하여 차량의 도난사태가 발생하고 있다는 것을 표시하게 되는 것이다.In addition, the present invention, as described above, by driving the ignition cut-off unit 60 to cut off the power supplied to the ignition coil (L1) at the same time turn on the transistor TR1 of the transmitter driving unit 70 to install a transmitter ( Since a synchronization signal is provided to transmit a transmission signal at 71, the receiver 72 carried by the driver receives the transmission signal of the transmitter 71 to indicate that a vehicle theft is occurring.

한편, 운전자가 키(10)를 키홀(22a)에 삽입하여 키고유코드가 일치하는 경우에는 상기 수광부(PTR)가 상기 관통공(21Ha,21HB,22Ha,22Hb)과 천공홀(11H)을 통해 전달되는 발광부(PD)의 빛을 감지하여 인버터(G2)를 통해 로우레벨의 신호를 출력하게 되므로 상기 앤드게이트회로(G2)는 로우레벨의 신호를 출력하게 됨에 따라 상기 점화차단부(60)와 상기 송신기구동부(70)는 구동하지 않게 되며 정상적으로 엔진시동이 걸리게 되는 것이다.On the other hand, when the driver inserts the key 10 into the key hole 22a and the key unique code matches, the light receiving part PTR passes through the through holes 21Ha, 21HB, 22Ha, 22Hb and the drilling hole 11H. Since the light of the light emitting unit PD is transmitted to output a low level signal through the inverter G2, the AND gate circuit G2 outputs a low level signal, and thus the ignition blocking unit 60. And the transmitter driver 70 is not driven and normally starts the engine.

이상에서 설명한 바와같이 본 발명은 종래의 천공키와 키실린더를 이용하는 도난방지회로를 제공함으로써 한단계 진보된 보안성으로 차량의 도난을 방지할 수 있도록 하는 효과가 있다.As described above, the present invention provides an anti-theft circuit using a conventional punch key and a key cylinder, thereby preventing theft of a vehicle with advanced security.
