Abstract

본 발명은 자동차 충돌시의 연료 공급차단 시스템에 관한 것으로 이를 더욱 상세하게 설명하면 자동차 사고시 에어백의 전개와 동시에 연료펌프 모터를 강제로 멈추게 하여 연료 누출에 의한 화재를 방지하는 시스템에 관한 것으로 충격 센서의 감지에 의하여 에어백이 전개는 에어백 시스템을 이용하여, 에어백 시스템의 전개신호와 동시에 연료펌프 작동을 멈추게 하는 신호를 주는 것을 특징으로 하는 자동차 충돌시의 연료 공급차단 시스템에 관한 것이다.The present invention relates to a fuel supply cut-off system in a car crash. The present invention relates to a system for preventing a fire caused by a fuel leak by forcibly stopping a fuel pump motor at the same time as an air bag deployment during a car accident. The deployment of the airbag by the detection relates to a fuel supply cut-off system in the event of a vehicle crash, characterized in that the airbag system is used to give a signal to stop the operation of the fuel pump simultaneously with the deployment signal of the airbag system.

Claims (1)

자동차 연료펌프의 안전 시스템에 있어서, 비교기1(1)과 비교기2(2)와 비교기3(3)과 릴레이2(4)와 연료펌프모터(5)로 이루어진 시스템을 이용하여 에어백 센서가 작동하여 에어백이 작동하게 되면 차량이 충돌한 상황으로 비교기1(1)과 비교기2(2)로의 신호가 HIGH가 되어 비교기1(1)과 비교기2(2)의 출력은 5볼트로 AND GATE 입력으로 들어가서 AND GATE 의 출력은 HIGH로 되어서 비교기3(3)의 플러스 단자로의 입력이 5볼트가 되고 비교기3(3)의 출력은 12볼트가 출력되어 릴레이2(4)로 인가되어서 연료펌프모터(5)는 작동을 정지하게 되는 것을 특징으로 하는 자동차 충돌시의 연료 공급차단 시스템.In the safety system of an automobile fuel pump, an airbag sensor is operated by using a system consisting of a comparator 1 (1), a comparator 2 (2), a comparator 3 (3), a relay 2 (4), and a fuel pump motor (5). When the airbag is activated, the signals of comparator 1 (1) and comparator 2 (2) become HIGH due to the collision of the vehicle, and the outputs of comparator 1 (1) and comparator 2 (2) are 5 volts to the AND GATE input. The output of AND GATE is HIGH, so the input to the positive terminal of comparator 3 (3) becomes 5 volts, and the output of comparator 3 (3) is output to 12 volts and applied to relay 2 (4) to supply the fuel pump motor (5). The fuel supply cutoff system in the event of a vehicle crash, characterized in that the operation is stopped.
