차량의 충돌사고시 화재발생 차단방법 및 그 장치Fire prevention method and device thereof in case of collision of vehicle

본 발명은 차량의 충돌사고시 화재발생 차단방법 및 그 장치에 관한 것으로, 특히 차량의 충돌사고시 에어백의 폭발시 그 배터리의 플러스 단자로부터 발생하는 전류와 얼터네이터로부터 발생하는 전류 및 연료공급라인으로부터의 연료누설 등을 방지하여 1차적인 화재요인을 미연에 차단함으로써 화재의 위험을 근본적으로 억제하는, 차량의 충돌사고시 화재발생 차단방법 및 그 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method for preventing a fire from occurring in a crash of a vehicle and a device thereof, in particular, a current generated from a positive terminal of the battery, an electric current generated from an alternator, and a fuel leakage from a fuel supply line, when an airbag explodes in a crash of a vehicle. The present invention relates to a method and a device for preventing fire in the event of a collision of a vehicle, which fundamentally suppresses the risk of fire by preventing a fire and preventing primary fire factors.

일반적으로 차량의 충돌사고시에는 차체가 파손되는 경우는 물론, 차체의 외부가 크게 파손되지 아니하더라도 다른 장치의 이탈에 의해 화재사고로 이어지는 경우가 빈번하였다.In general, during a crash of a vehicle, as well as the body is damaged, even if the exterior of the body is not largely damaged, it is often the case that leads to a fire accident by the separation of other devices.

즉, 차량의 충돌사고시 발생하는 충격력에 의해 에어백(장착된 차량의 경우)이 폭발하여 그 에어백의 폭발장치에 전원을 공급하는 배터리의 플러스측 전원이 노출되고, 또한 얼터네이터에서 전류가 생성될 뿐만 아니라, 이들의 각 노출된 전류에 연료탱크와 공급파이프로부터 공급되는 연료가 접촉하여 폭발, 화재로 이어지는 사고가 빈번히 발생되고 있다.That is, the airbag (in the case of a mounted vehicle) is exploded by the impact force generated in the crash of the vehicle, and the positive side power of the battery supplying power to the explosion device of the airbag is exposed, and the alternator generates current as well. In addition, accidents leading to explosion and fire are frequently caused by the contact of the fuel supplied from the fuel tank and the supply pipe to each of the exposed currents.

이처럼 차량의 충돌사고시 노출된 전류와 연료의 접촉에 의한 폭발사고로 인하여 방지할 수 있었던 귀중한 인명을 잃어 버리거나 막대한 물적피해를 입어야만 하였다.Thus, in the crash of the vehicle, valuable lives that could be prevented due to an explosion caused by the contact of exposed current and fuel had to be lost or suffered substantial physical damage.

본 발명의 목적은, 차량으 충돌사고시 전류의 노출과 연료의 공급라인을 차단하여 화재의 발생요인을 근본적으로 방지함으로써, 인명피해는 물론, 막대한 재산손실의 초래를 억제하는, 차량의 충돌사고시 화재발생 차단방법 및 그 장치를 제공하기 위한 것이다.It is an object of the present invention to prevent the occurrence of enormous property loss as well as human damage by preventing the occurrence of fire by fundamentally preventing the exposure of the current and the fuel supply line in the event of a vehicle crash, fire in the event of a vehicle crash An object of the present invention is to provide a blocking method and an apparatus thereof.

도면과 같이, 배터리(10)와 이로부터 각 전장품으로 흘러가는 전원의 경로에 릴레이(Ry1)가 연결되고, 배터리(10)와 얼터네이터(20)를 연결하는 전원의 경로에 릴레이(Ry2)가 연결되며, 연료탱크(30)의 연료펌프모터(40)를 전원연결하는 경로에 릴레이(Ry3)가 연결되어 있다.As shown in the figure, a relay Ry1 is connected to a path of a power source flowing from the battery 10 and the respective electrical appliances, and a relay Ry2 is connected to a path of a power source connecting the battery 10 and the alternator 20. The relay Ry3 is connected to a path for connecting the fuel pump motor 40 of the fuel tank 30 to a power source.

또한 상기의 릴레이(Ry1,Ry2,Ry3)들은 E.C.U(50)의 출력단에 연결되어 E.C.U(50)의 입력신호에 대하여 OFF되도록 되어 있다.In addition, the relays Ry1 , Ry2 , and Ry3 are connected to an output terminal of the ECU 50 so as to be turned off with respect to an input signal of the ECU 50.

아울러 E.C.U(50)의 입력단에 충돌감지센서(60)가 연결되어 차량의 충돌사고시 충격값을 E.C.U(50)에 인가하도록 되고, E.C.U(50)의 다른 입력단에 에어백(70)의 작동제어부가 연결되어 차량의 충돌에 의한 에어백(70)의 폭발시 그 신호를 E.C.U(50)에 인가하도록 되어 있다.In addition, the collision detection sensor 60 is connected to the input terminal of the ECU 50 to apply the impact value to the ECU 50 in the event of a collision of the vehicle, and the operation control unit of the airbag 70 is connected to the other input terminal of the ECU 50.

따라서 본 발명은, 엔진이 시동되고 차량이 주행하는 상태에서 충돌사고가 발생하면, 이와 동시에 충돌감지센서(60)로부터 충격량이 감지되며, 감지된 충격값이 E.C.U(50)에 인가되면서 그 E.C.U(50)의 설정값을 벗어날 경우 E.C.U(50)는 폭발명령을 에어백(70)에 전달한다.Therefore, in the present invention, when a collision accident occurs while the engine is started and the vehicle is running, at the same time the impact amount is detected from the collision detection sensor 60, the detected shock value is applied to the ECU 50, the ECU ( The ECU 50 transmits an explosion command to the airbag 70 when it is out of the set value of 50).

여기서 에어백(70)이 폭발하여 정면충돌시 운전자의 상반신과 두부의 치명적인 손상을 억제하며, 또한 에어백(70)이 폭발하였을 경우 각 릴레이(Ry1,Ry2,Ry3)들을 동시에 신속히 OFF시킨다.Here, the airbag 70 is exploded to suppress the fatal damage of the upper body and head of the driver during a frontal collision, and when the airbag 70 is exploded, the relays (Ry1, Ry2, Ry3) are quickly turned off at the same time.

릴레이(Ry1)의 OFF시는 모든 전장품으로 흐르는 전류를 차단하고, 릴레이(Ry2)의 OFF시는 얼터네이터(20)에 흐르는 전류를 차단하며, 또한 릴레이(Ry3)의 OFF시는 연료펌프모터(40)의 작동을 정지시켜 연료공급라인의 연료를 차단시킨다.When the relay Ry1 is OFF, the current flowing to all the electric appliances is cut off, and when the relay Ry2 is OFF, the current flowing to the alternator 20 is cut off, and when the relay Ry3 is OFF, the fuel pump motor 40 is turned off. ) To shut off the fuel in the fuel supply line.

이처럼 전류에 의해 구동되는 모든 전장품들의 전원을 차단하고 연료의 공급을 차단하여 충돌에 의한 화재의 발생요인을 제거한다.In this way, all electric appliances driven by electric current are cut off and fuel supply is cut off to eliminate the cause of fire caused by collision.

이상과 같이 본 발명은, 배터리 및 각 전장품을 연결하는 전원공급경로와, 연료펌프모터의 전원연결부에 릴레이를 각기 연결하고, 이들 릴레이를 E.C.U의 출력단에 연결하며, 또한 E.C.U의 입력단에 충돌감지센서와 에어백의 작동제어부를 연결하여, 차량의 충돌에 의한 일정값 이상의 충격발생시 각 릴레이를 동시에 OFF 시켜 전원공급라인과 연료공급라인을 차단시킴으로써, 화재의 위험을 근본적으로 억제하는 것은 물론, 탑승자의 인명사고와 물적피해를 적극적으로 방지하는 효과를 갖는다.As described above, the present invention, the power supply path for connecting the battery and each electrical appliance, and the relay connected to the power connection portion of the fuel pump motor, respectively, these relays are connected to the output terminal of the ECU, and also the collision detection sensor at the input terminal of the ECU By connecting the airbag and the operation control unit of the airbag, when the shock occurs over a certain value due to the collision of the vehicle, each relay is turned off at the same time to cut off the power supply line and the fuel supply line, thereby fundamentally suppressing the risk of fire, It has the effect of actively preventing accidents and material damage.
