Description

가스 자동차의 안전장치{Security device of gas automobile}Security device of gas automobile

본 발명은 가스 자동차의 안전장치에 관한 것으로서, 특히 가스 주입구를 개폐하는 캡이 열리거나 닫힘에 따라 가스탱크로 부터 엔진으로 가스가 이동하는 연결관의 중간부분을 개방하거나 닫히도록 하여 가스 충진시에 엔진이 자동으로 꺼지도록 하므로서, 가스 충진시 폭발사고의 위험을 미연에 방지하고, 가스 충진후 캡을 닫지 않고 출발하는 실수를 범하지 않도록 한 가스 자동차의 안전장치에 관한 것이다.The present invention relates to a safety device of a gas vehicle, and in particular, to open or close the middle portion of the connecting pipe for moving the gas from the gas tank to the engine as the cap opening and closing the gas inlet opening or closing the gas filling The engine automatically shuts off, preventing the risk of explosion accidents when filling the gas, and a gas vehicle safety device that prevents the mistake of starting without closing the cap after filling the gas.

가스 자동차는 엔진의 연소동작에 필요한 연료로서 압축 천연가스를 사용하고 있다.Gas vehicles use compressed natural gas as a fuel for combustion operation of engines.

그런데, 압축 천연가스는 일반 액체연료에 비해 폭발위험이 크므로, 가스 충진시에는 엔진이 정지되도록 하는 것을 법으로 규제하고 있는 실정이다.However, since compressed natural gas has a greater risk of explosion than general liquid fuel, it is regulated by law to stop the engine when filling gas.

즉, 가스 충진을 위해서는 가스 주입구를 막고있는 캡을 열고 가스탱크에 가스를 주입하게 되는데, 이때 엔진이 동작하는 상태이면 종종 충진되는 가스가 폭발하게 되는 위험이 있으므로, 가스충진시에는 엔진이 정지되도록 하는 것을 법으로 규제하는 것이다.That is, in order to fill the gas, the cap that blocks the gas inlet opening is opened and gas is injected into the gas tank. In this case, when the engine is in operation, the gas is often charged, so the engine is stopped when the gas is filled. It is regulated by law.

그러나, 종래에는 가스 자동차에 별도의 안전장치가 구비되어 있지 않았기 때문에, 가스 충진시에는 운전자가 알아서 엔진을 정지시키거나 가스 충진소의 직원이 운전자에게 엔진을 꺼줄것을 당부하여 엔진을 정지시키고 있는 실정이며, 만약 운전자나 가스 충진소의 직원 모두 엔진 끄는 것을 잊어버렸을 경우에는 잘못하면 대형의 폭발사고가 발생하게 되는 문제점이 있었다.However, in the past, since the gas vehicle is not equipped with a separate safety device, when the gas is filled, the driver stops the engine by himself or the staff of the gas filling station asks the driver to turn off the engine. If both the driver and the staff of the gas filling station forgot to turn off the engine, there was a problem that a large explosion accident occurs if wrong.

또한, 가스 충진 후 가스 충진소 직원이 캡을 닫아주지 않으면 운전자는 캡이 열린줄도 모르고 그냥 주행을 하게되는 문제점 또한 발생하고 있다.In addition, if the gas filling station staff does not close the cap after filling the gas, the driver does not even know that the cap is open, there is also a problem that you are just driving.

따라서, 상기 문제점을 해결하기 위한 본 발명은 가스 주입구를 개폐하는 캡이 열리거나 닫힘에 따라 가스탱크로 부터 엔진으로 가스가 이동하는 연결관의 중간부분을 개방하거나 닫히도록 하여 가스 충진시에 엔진이 자동으로 꺼지도록 하므로서, 가스 충진시 폭발사고의 위험을 미연에 방지하고, 가스 충진후 캡을 닫지 않고 출발하는 실수를 범하지 않도록 한 가스 자동차의 안전장치를 제공함을 목적으로 한다.Accordingly, the present invention for solving the above problems is to open or close the middle portion of the connecting pipe to move the gas from the gas tank to the engine as the cap opening and closing the gas inlet opening or closing the engine at the time of gas filling It is intended to provide a safety device for a gas vehicle that prevents the risk of an explosion accident during gas filling in advance and prevents the mistake of starting without closing the cap after filling the gas.

상기 도면에 의하면, 본 발명은 캡 센서(4), 밸브(5), 릴레이 스위치(7), 이시유(8)로 대별 구성된다.According to the drawing, the present invention is roughly composed of a cap sensor 4, a valve 5, a relay switch 7, and an oil.

상기 캡 센서(4)는 가스탱크(1)의 연료 주입구를 막고있는 캡이 열린상태인지 닫힌상태인지를 감지하는 것으로서, 감지되는 캡의 상태에 따라 각기 다른 전기신호를 이시유(8)로 출력하도록 구성한다.The cap sensor 4 detects whether the cap blocking the fuel inlet of the gas tank 1 is open or closed, and outputs different electric signals to the ishiyu 8 according to the detected cap state. Configure to

상기 밸브(5)는 가스탱크(1)와 엔진(2)을 연결하는 연결관(3)의 중간부분에 설치되어 캡이 열리거나 닫힘에 따라 연결관(3)을 개방 또는 차단시키도록 구성하였다.The valve 5 is installed in the middle portion of the connecting pipe 3 connecting the gas tank 1 and the engine 2 so as to open or close the connecting pipe 3 as the cap is opened or closed. .

상기 밸브(5)는 전압이 입력될때에는 연결관(3)을 차단시키고, 전압이 입력되지 않을 때에는 연결관(3)을 개방시켜 가스탱크(1)의 가스연료가 엔진(2)으로 공급되도록 하는 것이다.The valve 5 shuts off the connecting pipe 3 when the voltage is input, and opens the connecting pipe 3 when the voltage is not input so that the gas fuel of the gas tank 1 is supplied to the engine 2. It is.

상기 릴레이스위치(7)는 이시유(8)로 부터 공급되는 제어전압으로 소정의 전기장을 발생시키는 코일(L)과, 상기 코일(L)에서 전기장이 발생할때 온동작하여 밧데리(6)의 전압을 밸브(5)로 공급하는 스위치(SW)로 구성된다.The relay switch 7 is a coil (L) for generating a predetermined electric field with a control voltage supplied from the oil (8), and when the electric field is generated in the coil (L) is turned on to operate the voltage of the battery (6) It is composed of a switch (SW) for supplying to the valve (5).

상기 이시유(8)는 캡 센서(4)의 감지결과에 따라 상기 릴레이스위치(7)를 온/오프 제어하는 것으로, 상기 캡 센서(4)의 감지결과 캡이 열린 상태이면 릴레이스위치(7)의 코일(L)로 제어전압을 출력하여 스위치(SW)가 온동작하도록 하여 밸브(5)가 닫히도록 하고, 상기 캡 센서(4)의 감지결과 캡이 닫힌 상태이면 릴레이스위치(7)를 오프시켜 밸브(5)가 개방되도록 하는 것이다.The Ishiyu 8 controls the relay switch 7 on / off according to the detection result of the cap sensor 4, and the relay switch 7 if the cap is opened as a result of the detection of the cap sensor 4. Outputs a control voltage to the coil L so that the switch SW is turned on so that the valve 5 is closed. If the cap is closed, the relay switch 7 is turned off. To open the valve (5).

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

먼저, 캡이 닫힌 상태를 설명하면,First, describe the closed cap.

캡 센서(4)의 감지결과 캡이 닫힌 상태로 감지되면, 이시유(8)는 릴레이스위치(7)를 오프시켜 밧데리(6) 전압이 밸브(5)로 공급되지 않도록 한다.When the cap sensor 4 detects that the cap is closed, the oil 8 turns off the relay switch 7 so that the battery 6 voltage is not supplied to the valve 5.

이에따라, 상기 밸브(5)가 개방되어 가스탱크(1)의 가스가 연결관(3)을 통해 엔진(2)으로 공급되므로서, 엔진(2)이 정상적으로 동작하게 되는 것이다.Accordingly, the valve 5 is opened so that the gas in the gas tank 1 is supplied to the engine 2 through the connecting pipe 3, so that the engine 2 operates normally.

즉, 캡이 닫힌상태이면, 자동차가 정상적으로 주행하거나 정지된 상태이므로 가스의 폭발위험이 없으므로 밸브(5)가 개방되어 가스탱크(1)의 연료가 엔진(2)으로 공급되는 것이다.That is, if the cap is closed, since the vehicle is normally driven or stopped, there is no risk of explosion of the gas, so that the valve 5 is opened to supply the fuel of the gas tank 1 to the engine 2.

한편, 캡 센서(4)의 감지결과 캡이 열린 상태로 감지되면, 이시유(8)는 캡 센서(4)의 감지결과에 따라 릴레이스위치(7)를 온동작시켜 밧데리(6)의 전압이 밸브(5)로 공급되도록 하고, 상기 밸브(5)는 입력되는 전압에 의해 연결관(3)을 차단시킨다.On the other hand, when the sensing result of the cap sensor 4 is detected as the cap is open, Ishiyu 8 operates the relay switch 7 according to the sensing result of the cap sensor 4 to the voltage of the battery (6) It is supplied to the valve (5), the valve (5) shuts off the connecting pipe (3) by the input voltage.

상기 밸브(5)가 연결관(3)을 차단하면 가스탱크(1)의 가스가 엔진(2)으로 공급되지 않게되므로 엔진(2)은 정지하게 된다.When the valve 5 blocks the connection pipe 3, the gas of the gas tank 1 is not supplied to the engine 2, and thus the engine 2 is stopped.

즉, 캡이 열린 상태는 가스탱크(1)에 가스를 충진하거나, 가스 충진 후 캡을 닫지 않은 상태가 되므로, 밸브(5)를 닫아 엔진(2)이 정지하도록 하므로서 폭발위험을 미연에 방지할 수 있게되는 것이다.In other words, the cap is opened so that the gas tank 1 is not filled with gas, or the cap is not closed after the gas is filled, so that the engine 2 is stopped by closing the valve 5 to prevent the explosion risk. It will be possible.

이상에서 설명한 바와같이 본 발명은 가스 주입구를 개폐하는 캡이 열리거나 닫힘에 따라 가스탱크로 부터 엔진으로 가스가 이동하는 연결관의 중간부분을 개방하거나 닫히도록 하여 가스 충진시에 엔진이 자동으로 꺼지도록 하므로서, 가스 충진시 폭발사고의 위험을 미연에 방지하고, 가스 충진후 캡을 닫지 않고 출발하는 실수를 범하지 않도록 한 가스 자동차의 안전장치이다.As described above, according to the present invention, the engine is automatically turned off during gas filling by opening or closing the middle portion of the connecting pipe through which gas flows from the gas tank to the engine as the cap for opening and closing the gas inlet is opened or closed. It is a safety device for gas vehicles that prevents the risk of explosion accidents when filling gas and prevents the mistake of starting without closing the cap after filling the gas.
