In general, a fuel device of a vehicle includes a fuel tank 10 for storing fuel, a fuel pipe 20 through which fuel passes, a vaporizer 50 for controlling a mixer, and a fuel tank as a part for supplying a suitable mixer required by an engine. And a fuel pump 30 for sending fuel to the vaporizer 50 at 10, a fuel filter 40 for removing impurities in the fuel, and the like. In addition, the fuel pump 30 is controlled using an electronic control unit (hereinafter referred to as ECU), which is a kind of microcomputer, so that the supply of the mixer required by the engine is more accurate than the vaporizer method.
도 2는 일반적인 연료 펌프의 전원 배선도이다. 도 1에 도시한 것과 같은 구성 중 종래의 연료 펌프(30)는 차량의 시동 스위치(60)가 작동하면 차량용 축전지(70)로부터 전원을 공급받아 무조건 연료 펌프(50)를 작동시키므로 모터가 회전하여 연료를 펌핑한다. 이로 인해 차량이 충돌하거나 전복되었을 때도 전원(70)이 연료 펌프(30)에 연결되어 있으면 계속적으로 연료가 누출되고, ECU에서 엔진이 오프되었을 때 연료 펌프(30)가 작동하지 않도록 제어하더라도 연료 파이프(20) 내에는 연료가 계속 남아 있어, 누출이 일어나 화재가 발생할 수 있는 문제점이 있었다.2 is a power supply wiring diagram of a general fuel pump. In the configuration as shown in FIG. 1, the conventional fuel pump 30 receives power from the vehicle storage battery 70 when the start switch 60 of the vehicle operates to operate the fuel pump 50 unconditionally, so that the motor rotates. Pump the fuel. As a result, fuel is continuously leaked when the power supply 70 is connected to the fuel pump 30 even when the vehicle crashes or rolls over, and the fuel pipe is controlled so that the fuel pump 30 does not operate when the engine is turned off in the ECU. There was a problem that the fuel remains in (20), a leak may occur and a fire may occur.

이하에서는 첨부도면을 참조하여 본 고안의 바람직한 실시예에 따른 차량 사고시 연료 누출 방지 장치에 대해서 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the fuel leakage preventing device in a vehicle accident according to a preferred embodiment of the present invention.
도 3은 본 고안의 차량 사고시 연료 누출 방지 장치의 시스템 블록도이다. 도 3에 도시한 바와 같이, 본 고안의 연료 누출 방지 시스템은 차량의 시동 스위치(60), 차량의 각 부에 필요한 전원을 공급하는 차량용 축전지(70), 연료 펌프(30)를 제어하여 혼합기를 조절하는 ECU(80), 일정한 수준 이상의 충격을 받으면 스위치 연결이 떨어져 신호를 전달하지 않는 연료 차단 스위치(90), ECU(80)와 연료 차단 스위치(90)로부터 들어오는 신호를 비교하여 차량에 사고가 발생했는지를 알 수 있게하는 비교기(110), 비교기(110)로부터 입력된 신호를 분석하여 연료 펌프(30)를 정상 동작시킬 것인지 역회전시킬 것인지를 판단하는 제어부(120), 및 제어부(120)가 연료 펌프(30)를 역회전시킬 때 일정 시간 동안만 연료 펌프를 작동하게 하는 타이머(130) 등으로 구성되어 있다.3 is a system block diagram of a fuel leakage preventing apparatus in a vehicle accident of the present invention. As shown in FIG. 3, the fuel leakage prevention system of the present invention controls a starter switch 60 of a vehicle, a vehicle storage battery 70 for supplying power required for each part of the vehicle, and a fuel pump 30. The ECU 80 to adjust, compare the signals coming from the fuel cut-off switch 90, the ECU 80 and the fuel cut-off switch 90 that does not transmit a signal when the switch is disconnected when a certain level of shock is received, the accident Comparator 110 to determine whether it has occurred, the control unit 120 to determine whether to operate the fuel pump 30 to normal operation or reverse by analyzing the signal input from the comparator 110, and the control unit 120 Is composed of a timer 130 and the like to operate the fuel pump only for a predetermined time when the fuel pump 30 is rotated back.
이러한 구성에서 차량이 충돌하거나 전복할 때의 충격으로 연료 차단 스위치(90)의 연결이 끊어지면 비교기(110)가 이를 감지하여 제어부(120)에 신호를 보내고, 제어부(120)는 사고를 인식하여 연료가 누출되지 않도록 타이머(130)에 저장된 시간 동안 연료 펌프(30)를 역회전시켜 연료 파이프(20) 내에 있는 연료를 연료 탱크(10)쪽으로 흡입시킨다. 물론 정상적인 상태에서는 ECU(80)와 연료 차단 스위치(90)로부터 신호가 정상적으로 들어오므로 ECU의 제어하에 연료 펌프(30)는 연료를 공급한다.In this configuration, when the fuel cutoff switch 90 is disconnected due to an impact when the vehicle collides or overturns, the comparator 110 detects this and sends a signal to the controller 120, and the controller 120 recognizes an accident. The fuel pump 30 is reversely rotated for the time stored in the timer 130 to suck the fuel in the fuel pipe 20 toward the fuel tank 10 so that fuel does not leak. Of course, since the signal normally comes from the ECU 80 and the fuel cutoff switch 90 in the normal state, the fuel pump 30 supplies fuel under the control of the ECU.
본 고안의 차량 사고시 연료 누출 방지 장치는 전술한 실시예에 국한되지 않고 본 고안의 기술 사상이 허용하는 범위 내에서 다양하게 변형하여 실시할 수가 있다.Fuel leakage preventing device in the case of a vehicle accident of the present invention is not limited to the above-described embodiment can be carried out variously modified within the range allowed by the technical idea of the present invention.
이상에서 설명한 바와 같은 본 고안의 차량 사고시 연료 누출 방지 장치에 따르면 차량의 충돌이나 전복시 일정 시간 연료 펌프를 역방향으로 작동시키므로 연료 파이프 내에 남아있는 연료의 누출을 방지하여 화재가 발생하는 것을 막을 수 있는 효과가 있다.According to the fuel leakage prevention device in the vehicle accident of the present invention as described above, by operating the fuel pump in a reverse direction during the collision or overturning of the vehicle, it is possible to prevent the occurrence of fire by preventing the leakage of fuel remaining in the fuel pipe. It works.
