일반적으로, 차량으로 주행시 커브길을 고속으로 코너링하다가 원심력에 의해 차량이 전복되거나 또는 차량의 운전자가 졸음운전을 하다가 차량이 도로바깥쪽 아래로 추락되어 전복되게 되면 충격에 의해 차량의 엔진쪽으로 연결되는 연료공급계통에 장애가 생기게 되고 그에 따라 차량용 연료탱크(도시되지 않음)로부터 차량의 엔진측에 연료가 계속 공급되게 되는데 이때, 소정의 충격에 의해 차량의 엔진에 전기 스파크가 생기게 되면 점화가 되어 화재가 발생되게 된다.In general, when the vehicle is overturned by a centrifugal force while the vehicle is overturned by a centrifugal force or the driver of the vehicle is drowsy and the vehicle falls down the outside of the road and is overturned, it is connected to the engine of the vehicle by the impact. The fuel supply system is interrupted, and thus fuel is continuously supplied from the vehicle fuel tank (not shown) to the engine side of the vehicle. At this time, when an electric spark is generated in the engine of the vehicle due to a predetermined shock, it is ignited to cause a fire. Will be generated.
또한, 상기 엔진룸(도시되지 않음)에 화재가 발생된 상태에서 불꽃이 연료계통을 따라 차량의 연료탱크까지 붙게 되면 곧이어 상기 연료탱크가 폭팔하게 된다.In addition, when the flame is attached to the fuel tank of the vehicle along the fuel system in a state where a fire occurs in the engine room (not shown), the fuel tank is immediately exploded.
즉, 종래의 차량에는 차량으로 주행도중 전복사고를 당하게 되었을 때 차량용 연료탱크가 폭팔되는 것을 방지하는 별도의 장치가 없음으로 인해 차량의 전복사고시 차량의 엔진룸에 화재가 발생되면 불꽃이 연료계통을 따라가 상기 연료탱크가 폭팔되게 되는 문제점이 있었다.That is, the conventional vehicle does not have a separate device that prevents the vehicle fuel tank from being blown up when the vehicle is subjected to a rollover accident while driving the vehicle. There was a problem that the fuel tank is exploded.
이에 본 고안은 상기와 같은 문제점을 해소하기위해 안출된 것으로, 차량으로 주행중 전복사고를 당했을 때 차량용 휠의 일측 소정부위에 구비되는 하중센서로부터 소정의 전기신호를 받은 차량용 연료펌프 구동모터가 자동으로 작동을 정지하게 됨으로써 차량의 전복사고시 차량엔진에 연료의 공급을 중단하게 됨으로써 전복된 차량에 화재가 발생되어 차량용 연료탱크가 폭팔되는 것을 방지할 수 있게 하도록 한 차량용 연료펌프 작동정지시스템를 제공하는데 그 목적이 있다.The present invention is designed to solve the above problems, the vehicle fuel pump driving motor automatically receives a predetermined electric signal from the load sensor provided on one side of the vehicle wheel when the vehicle is overturned while driving The purpose of the present invention is to provide a vehicle fuel pump operation stop system that prevents the fuel tank from being blown up due to a fire in the overturned vehicle by stopping the supply of fuel to the vehicle engine when the vehicle is overturned. There is this.
