* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

SW1: 연료주입구 도어 개폐스위치 SW2: 점화키스위치SW 1 : fuel injection door switch SW 2 : ignition key switch

SW3: 릴레이 상시 온 접점 RY : 릴레이SW 3 : Relay always on contact RY: Relay

SL : 연료주입구 도어 개폐용 솔레노이드코일SL: Solenoid coil for opening and closing the fuel injection door

본 고안은 자동차 연료주입구 개폐조절회로에 관한 것으로, 보다 상세하게는 엔진을 정지해야만 연료주입구의 도어를 열수 있게 하여 주유중의 화재발생등을 예방하기 위한 자동차 연료주입구 개폐조절회로에 관한 것이다.The present invention relates to an automobile fuel inlet opening and closing control circuit, and more particularly, to an automobile fuel inlet opening and closing control circuit for preventing the occurrence of a fire during fueling by opening the door of the fuel inlet only when the engine is stopped.

기존의 차량, 특히 승용차에서는 자동차키이로써 또는 차내에서 운전자의 스위치 조작으로 연료주입구 도어를 열어서 연료를 주입하게 되는데, 차량의 고급화에 따른 운전자의 편의를 위하여 차내에서 스위치 조작만으로 열리는 연료주입구 도어는 차량이 시동된채 주유함으로써 화재 발생등의 위험이 있게되므로, 주유중 시동이 꺼지는 장치가 필요하게 되었다.Existing vehicles, especially passenger cars, inject fuel by opening the fuel inlet door with a car key or by a driver's switch operation in the vehicle.For the convenience of the driver according to the advanced vehicle, the fuel inlet door opened only by the switch operation in the vehicle is a vehicle. Since the fueling is started, there is a risk of fire, etc., so a device is required to turn off the starting during fueling.

즉, 제1도에서와 같이 종래의 연료주입구 도어를 여는 회로구성은 스위치(SW1)를 조작하여 솔레이노이드코일(SL)에 배터리(B)전류를 흐르게 한 것이므로, 엔진시동이 켜진 상태에서도 연료주입구 도어가 개폐되고, 이는 휘발성이 강한 연료에 엔진시동에 따른 화재 위험성이 내포되어 있어서, 이의 대책이 절실히 요구되어 왔던 것이다.That is, as shown in FIG. 1, the conventional circuit configuration for opening the fuel inlet door is to operate the switch SW 1 so that the battery B current flows through the solenoid coil SL, so that the fuel is turned on even when the engine is turned on. The inlet door is opened and closed, which implies a fire risk due to the engine startup in the highly volatile fuel, so that countermeasures have been urgently required.

본 고안은 이와같은 위험성을 배재하기 위한 것으로, 엔진시동시에는 연료주입구 도어 개폐스위치를 온(ON)시켜도 연료주입구 도어가 열리지 않게되는 연료주입구 개폐조절회로를 제공하는데 본 고안의 목적이 있다.The present invention is intended to eliminate such a risk, the purpose of the present invention is to provide a fuel inlet opening and closing control circuit that does not open the fuel inlet door even when the fuel inlet door opening and closing switch (ON) when the engine is started.

이하, 첨부된 도면을 참고로하여 본 고안의 실시예를 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention with reference to the accompanying drawings as follows.

제2도에서 도시하고 있는 바와같이, 점화키스위치(SW2)를 통한 배터리(B)의 전압을 릴레이(RY)에 인가되게 연결하고, 또한 상기 배터리(B)의 전압은 상기 릴레이(RY)의 상시 온 접점(SW3)과 연료주입구 도어 개폐스위치(SW1)를 직렬로 연결하여 연료주입구 도어 개폐용 솔레노이드코일(SL)로 인가되게 연결하여 구성한다.As shown in FIG. 2 , the voltage of the battery B through the ignition key switch SW 2 is connected to the relay RY so that the voltage of the battery B is connected to the relay RY. It is composed by connecting the normally on contact (SW 3 ) of the fuel inlet door opening and closing switch (SW 1 ) in series to be applied to the fuel inlet door opening and closing solenoid coil (SL).

이와같이 구성된 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above are as follows.

제2도에서, 엔진시동을 끄지 않은 상태에서는 점화키스위치(SW2)가 온상태로 유지되므로 릴레이(RY)가 구동하여 릴레이의 상시 온 접점(SW3)은 열려 있게 된다. 따라서 이 상태에서 연료보급을 위해 연료주입구 도어 개폐스위치(SW1)를 온시키도 연료주입구 도어 개폐용 솔레노이드코일(SL)에는 배터리(B)의 전압이 공급되지 않으므로 연료주입구 도어는 록킹상태가 유지된다.In FIG. 2, since the ignition key switch SW 2 is kept on in the state where the engine start is not turned off, the relay RY is driven so that the normally on contact SW 3 of the relay is opened. Therefore, even if the fuel inlet door opening / closing switch SW 1 is turned on to supply fuel in this state, the voltage of the battery B is not supplied to the fuel inlet door opening / closing solenoid coil SL so that the fuel inlet door is locked. do.

한편, 엔진시동을 끄게되면 점화스위치(SW2)는 오프상태, 즉 열려진 상태로 되므로 릴레이 (RY)는 구동하지 않기 때문에 릴레이의 상시 온 접점(SW3)이 닫혀져, 이때에는 연료주입구 도어 개폐스위치(SW1)를 온시키면 연료주입구 도어 개폐용 솔레노이드코일(SL)에 배터리(B) 전압이 인가되므로 연료주입구 도어가 열려지게 되는 것이다.On the other hand, when the engine is turned off, since the ignition switch SW 2 is turned off, that is, the open state, the relay RY is not driven, and thus the normally on contact SW 3 of the relay is closed. When the SW 1 is turned on, the battery B voltage is applied to the solenoid coil SL for opening and closing the fuel inlet door, thereby opening the fuel inlet door.

이상에서 설명한 바와같은 본 고안은 연료주입구 도어개폐라인에 점화키스위치의 온/오프 상태에서 제어되는 릴레이의 접점을 부가하여 주는 것으로, 주유소에서 차량의 엔진을 끄지 않은 상태에서의 연료주입구에 따른 불의의 화재사고를 예방할 수 있는 특위의 효과가 나타나게 된다.The present invention as described above is to add a contact point of the relay controlled in the on / off state of the ignition key switch to the fuel inlet opening and closing line, inadvertent according to the fuel inlet without turning off the engine of the vehicle at the gas station The special effect of preventing a fire accident will be shown.
