상기와 같이 구성된 본 발명의 작용 및 효과를 상세히 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above in detail.
제1도 내지 제4도에 나타낸 바와 같이, 차량 충돌시 에어백 작동센서에 감지되는 충격 예를 들면 충격 가속도 30㎞/h 이상 발생시 에어백 작동센서(20)에서 에어백(10)으로 전류를 흘려 보내어 에어백 시스템이 작동되어 에어백을 터트린다.As shown in Figs. 1 to 4, when the impact detected by the airbag operation sensor during a vehicle crash, for example, when the acceleration of the acceleration is more than 30km / h, the airbag by flowing a current from the airbag operation sensor 20 to the airbag 10 The system is activated and blows up the airbag.
이 때, 에어백 작동센서(20)에서 에어백(10)으로 전기를 흘려 보내는 배선(21)에 연료차단용 콘트롤러(100)의 전원공급용 배선(22)(22')을 연결하면 에어백(10)과 연료차단용 콘트롤러(100)에 동시에 전원을 공급받게 된다.At this time, if the power supply wirings 22 and 22 'of the fuel cutoff controller 100 are connected to the wiring 21 for flowing electricity from the airbag operation sensor 20 to the airbag 10, the airbag 10 may be connected. Power is supplied to the controller 100 and the fuel cutoff at the same time.
따라서, 전원을 공급받은 콘트롤러(100)는 코일(130)(140)과 회전축(150)에 각각 전원을 연결하여 발생하는 자기장의 힘으로 회전축(150)이 회전을 하게 되고 이 회전축(150)의 회전에 의해 개폐조절드럼(230)과 이 개폐 조절드럼(230)의 연료 통과구멍(231)과 하부 밸브 케이스(240)의 연료공급파이프(40)(40')의 구멍이 일치한 상태 예를 들면 연료를 통과시키는 상태에서 상기 개폐 조절드럼(230)의 회전으로 연료 통과구멍(231)이 막힘으로써, 연료는 개폐조절밸브(200)를 통과 할 수 없어 자동 차단되어 엔진은 자동 정지되고 추가 연료공급이 없으므로 화재나, 폭발의 안전성을 크게 향상시킬 수가 있다.Therefore, the controller 100 is supplied with power to the rotary shaft 150 is rotated by the force of the magnetic field generated by connecting the power to the coil 130, 140 and the rotary shaft 150, respectively, An example of a state where the opening / closing control drum 230 and the fuel passage hole 231 of the opening / closing control drum 230 coincide with the holes of the fuel supply pipes 40 and 40 'of the lower valve case 240 are rotated. For example, when the fuel passage hole 231 is blocked by the rotation of the opening / closing control drum 230 in the state where the fuel is passed, the fuel cannot automatically pass through the opening / closing control valve 200, so that the engine is automatically stopped and the additional fuel is stopped. Since there is no supply, the safety of fire and explosion can be greatly improved.
이상과 같이 본 고안은 차량 충돌시 에어백이 작동됨과 동시에, 연료탱크 상부의 연료공급 파이프를 자동 차단함으로써 엔진이 자동정지되게 하여, 충격발생 후, 엔진 내에 추가 연료공급을 없애어 폭발이나 화재의 위험을 방지할 수가 있다.As described above, the present invention operates the airbag at the time of a vehicle collision and at the same time, automatically shuts off the fuel supply pipe at the top of the fuel tank so that the engine is automatically stopped. Can be prevented.
또한 별도의 센서를 사용하지 않고 에어백 작동센서와 연결하여 사용함으로써 부품절감 및 효율을 증가시킬 수가 있다.In addition, it can reduce parts and increase efficiency by connecting with airbag operation sensor without using a separate sensor.
