Description

이그니션 스위치를 이용한 차량도난 방지장치Vehicle anti-theft device using ignition switch

본 발명은 차량도난 방지장치에 관한 것으로, 특히 차량의 엔진을 시동하기 위해 시동키가 삽입되면 시동키에 장착된 건전지 스위치를 동작시켜 빛을 발생하여 엔진을 구동시키도록 한 이그니션 스위치를 이용한 차량도난 방지장치에 관한 것이다. 일반적으로 운전자가 차량을 주/정차한 상태에서 다른 일을 보기 위해 차량에서 자리를 비울때 차량의 도난방지를 위해 도어 윈도우를 올리고 도어키로 각 도어를 잠그게 되는데, 이때 상기 운전자가 차량에서 자리를 떠난 틈을 이용하여 차량 절도범들은 차량의 도어를 열고 차량내부로 칩입하여 내부에 있는 물건을 훔치기도 하고 차량을 절도해 가는 경우가 발생한다.The present invention relates to a vehicle anti-theft device, and in particular, when the ignition key is inserted to start the engine of the vehicle, a vehicle theft using an ignition switch to operate the battery switch mounted on the ignition key to generate light to drive the engine. It relates to a prevention device. In general, when the driver leaves the vehicle to see other things while the vehicle is parked / stopped, the door window is raised and the door keys are locked to prevent theft of the vehicle. Using the gaps, theft thieves open the door of the vehicle and break into the vehicle to steal the goods inside and steal the vehicle.

그리고, 차량의 도어에는 도어록 노브가 내장되어 있어 차량이나 차량내부의 물건을 훔치려는 사람이 간단한 도구만 이용해도 도어록 노브를 풀고 도어를 열어 차량이나 차량내부의 물품을 훔쳐 갈 수 있어, 이를 방지하기 위해서 종래의 차량도난방지장치는 도난 경보장치의 일측단자로 닫힘 상태에서 전류가 흐르고 풀림상태에서 전류가 흐르지 않는 도어록 노브와 릴레이가 연결되고 일측단자의 전원(+)과 연결된 릴레이의 타측단자가 헤드램프와 혼에 연결되어 구성된 것으로, 상기 차량도난 경보장치를 가동하고 있는 중에 도어록 노브가 풀리게 되어 전류가 흐르지 않게 되면 도난 경보장치가 릴레이를 가동시키게 되고 미도시된 릴레이가 통전됨으로써 헤드램프가 점등되고 혼이 울리게 된다.In addition, the door of the vehicle has a built-in door lock knob, so that anyone who steals the vehicle or the inside of the vehicle can unlock the door lock knob and open the door to steal the vehicle or the inside of the vehicle with a simple tool. The conventional vehicle anti-theft device is connected to the door lock knob and the relay, which is connected to the door lock knob which does not flow in the closed state and the current flows to the one terminal of the burglar alarm, and the other terminal of the relay is connected to the power supply (+) of the one terminal. If the door lock knob is released while the vehicle burglar alarm is running and no current flows, the burglar alarm activates the relay, and the head lamp is turned on by energizing the relay. The soul rings.

이와 같이 종래의 차량도난 경보장치에 있어서는 차량절도범이 도어를 열기 위해서는 차량 도어측에 설치된 도어록 장치의 도어키 실린더에 유사한 도어키를 삽입하여 도어록의 잠금작동을 해제시켜 절도를 하게 되고, 아울러 도어록 노브를 해제하지 않고 도어 글라스를 깨뜨려 차량내부로 칩입할때 도어록 노브가 잠김상태이므로 차량도난 경보장치가 작동되지 않아 차량을 도난당하는 문제점이 있었다.As described above, in the conventional vehicle burglar alarm device, in order to open the door, the vehicle thief inserts a similar door key into the door key cylinder of the door lock device installed on the vehicle door side, releases the lock operation and releases the door lock knob. Since the door lock knob is locked when the door glass is broken into the vehicle without releasing the door glass, the vehicle burglar alarm is not activated and the vehicle is stolen.

도 1은 본 발명 이그니션 스위치를 이용한 차량도난 방지장치의 개략도로서, 이에 도시한 바와 같이 시동키가 이그니션 스위치의 3단에 삽입되는 상태를 나타내고 있다.1 is a schematic diagram of a vehicle anti-theft device using the ignition switch of the present invention, and shows a state in which the ignition key is inserted into three stages of the ignition switch.

도 2는 본 발명 이그니션 스위치를 이용한 차량도난 방지장치의 회로도로서, 이에 도시한 바와 같이 시동키의 건전지 스위치가 온될때 램프가 온되어 이를 감지하는 조도센서와(3), 상기 조도센서(3)와 기준전압(VREF)을 비교하여 고전위신호를 출력하는 비교기(10)와, 상기 비교기(10)의 고전위신호를 입력받아 도통되는 트랜지스터(Q1)(20)와, 상기 트랜지스터(Q1)(20)가 도통됨에 따라 온되는 릴레이 스위치(30)와, 상기 릴레이 스위치(30)가 온됨에 따라 동작되는 시동모터(40)와, 상기 시동모터(40)가 동작됨에 따라 구동되는 엔진(50)으로 구성된 것으로, 이의 작용 및 효과를 상세히 설명하면 다음과 같다.Figure 2 is a circuit diagram of the vehicle anti-theft device using the ignition switch of the present invention, as shown in the illuminance sensor (3) and the illumination sensor (3) to detect the lamp is turned on when the battery switch of the ignition key is turned on And a comparator 10 which compares the reference voltage V REF and outputs a high potential signal, transistors Q1 and 20 that receive the high potential signal of the comparator 10 and are conducting. The relay switch 30 turned on as the 20 is turned on, the starter motor 40 operated as the relay switch 30 is turned on, and the engine 50 driven as the starter motor 40 is operated. ), And its operation and effects will be described in detail as follows.

차량을 운행하기전 운전자가 엔진을 구동하기 위해 시동키를 삽입시켜 3단위치에 고정하고, 이후 상기 운전자가 시동모터(40)를 작동시키기 위해 키이에 장착된 건전지 스위치를 누르면 램프가 점등되어 빛을 발생시켜 이를 조도센서가 감지하여 비교기(10)의 일측(+)에 입력되고 상기 비교기(10)의 타측(-)에 입력된 기준전압 (VREF)과 비교하여 상기 비교기(10)의 출력이 고전위신호일때 트랜지스터(Q1)(20)가 도통되어 릴레이 스위치(30)가 온되고 이에 따라 시동모터(40)가 작동되어 엔진(50)을 구동하게 된다.Before driving the vehicle, the driver inserts the ignition key to drive the engine and fixes it in the third position. Then, when the driver presses the battery switch mounted on the key to operate the ignition motor 40, the lamp is turned on and the light is turned on. To generate an output of the comparator 10 by comparing it with the reference voltage V REF input to one side (+) of the comparator 10 and input to the other side (−) of the comparator 10. In this high potential signal, the transistor (Q1) 20 is turned on so that the relay switch 30 is turned on, and thus the starter motor 40 is operated to drive the engine 50.

한편, 상기 시동키의 건전지 스위치가 동작되지 않아 램프가 점등되지 않으면 조도센서가 이를 감지하여 비교기(10)의 일측(+)에 입력되고 상기 비교기(10)의 타측(-)에 입력된 기준전압 (VREF)과 비교하여 상기 비교기(10)의 출력이 저전위신호일때 트랜지스터(Q1)(20)가 오프되어 릴레이 스위치(30)가 오프되고 이에 따라 시동모터(40)가 작동되지 않아 엔진(50)이 구동되지 않게 된다.On the other hand, if the lamp is not turned on because the battery switch of the starter key does not operate, the illumination sensor detects this and is input to one side (+) of the comparator 10 and the reference voltage input to the other side (-) of the comparator 10. Compared to V REF , when the output of the comparator 10 is a low potential signal, the transistors Q1 and 20 are turned off so that the relay switch 30 is turned off, and thus the starter motor 40 is not operated. 50) is not driven.

이상에서 상세히 설명한 바와 같이 본 발명은 차량절도범이 건전지 스위치 및 램프가 장착되지 않은 시동키를 삽입하여 차량을 도난하려 할때 이그니션 스위치 내부에 장착된 조도센서에서 빛을 감지하지 않아 차량에 시동이 걸리지 않게 함으로써 차량이나 차량내부 물품의 도난을 방지하는 효과가 있다.As described in detail above, in the present invention, when a thief tries to steal a vehicle by inserting a ignition key that is not equipped with a battery switch and a lamp, the vehicle does not start because the light sensor does not sense light from the illuminance sensor mounted inside the ignition switch. This prevents theft of the vehicle or the goods inside the vehicle.
