Description

수소자동차의 가스누설시 안전장치Safety device in case of gas leakage of hydrogen car

본 발명은 수소자동차의 수소가스 누설시 운전자의 안전사고를 방지하는 안전장치에 관한 것이다.The present invention relates to a safety device that prevents a driver's safety accident in case of hydrogen gas leakage of a hydrogen vehicle.

수소자동차는 수소가스(H2)를 연료로 사용하므로써 배기가스 배출량을 현저하게 저감시킬수 있는 자동차로서 현재까지는 수소연료의 제조 비용이 많이들어 크게 실용화되지는 못하고 있으나 제조비용이 낮춰질 경우 바닷물 등 그 자원이 무한정한 미래형 자동차이다.Hydrogen cars are vehicles that can significantly reduce emissions by using hydrogen gas (H 2 ) as a fuel. Until now, hydrogen cars are expensive due to the high production cost of hydrogen fuel. It is a futuristic car with unlimited resources.

그러나 수소자동차는 가스연료를 사용함에 따라 항상 가스누설의 위험성을 안고 있다.However, hydrogen cars are always at risk of gas leakage as they use gas fuel.

이에따라 수소자동차의 경우 가스누설시 도 2에 도시하는 것과 같이 가스누설감지기(1)가 가스누설을 감지하게 되면 운전석에 마련된 경보등(2)과 경보신호음발생기(3)를 통해 운전자에게 위험 상황임을 인식토록하여 질식이나 폭발에 따른 안전사고를 예방토록 하고 있다.Accordingly, in the case of hydrogen vehicles, when the gas leakage detector 1 detects a gas leakage, as shown in FIG. 2, the hydrogen vehicle recognizes that the driver is in a dangerous situation through an alarm light 2 and an alarm signal generator 3 provided in the driver's seat. This prevents safety accidents caused by asphyxiation or explosion.

그러나 차량의 주행중에는 유리창문이 닫혀져 있는 차실내의 밀폐상태로 운전되는 것이 통상적이므로 경보기가 작동된 시점에서는 이미 상당량의 가스누설이 이루어진 상태이어서 누설된 가스가 차실내에 침입하는 경우 운전자의 건강을 악화시키고 심할 경우 질식 또는 화재를 유발하게 되므로써 안전사고의 원인이 될 수 있다.However, while the vehicle is being driven, it is usually operated in a closed state in a vehicle with closed glass windows. Therefore, when the alarm is activated, a considerable amount of gas leakage has already occurred. It can be a cause of safety accident by worsening and causing severe suffocation or fire.

이에 본 발명은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 바는Accordingly, the present invention has been proposed in view of the above problems, and has as its object

수소가스 연료가 누설시 이를 경보하여 운전자에게 알려줄 뿐 아니라 차실내를 자동으로 환기토록 하여 운전자의 건강 및 안전을 지켜주게 되는 수소자동차의 가스누설시 안전장치를 제공하는 데 있다.When hydrogen gas fuel leaks, it not only notifies the driver and alerts the driver, but also provides a safety device in case of gas leakage of the hydrogen vehicle, which protects the driver's health and safety by automatically ventilating the interior of the vehicle.

상기한 목적을 달성하기 위하여 본 발명은 수소가스의 누설을 감지하는 수소가스 누설감지기와, 그 감지기로부터 신호출력시 이를 운전자에게 알려주는 경보등과 경보음 발생기로 구성되는 수소자동차의 가스누설 경고장치에 있어서,In order to achieve the above object, the present invention provides a gas leakage warning device for a hydrogen vehicle, comprising a hydrogen gas leak detector for detecting a leak of hydrogen gas, and an alarm lamp and an alarm sound generator to notify the driver when a signal is output from the detector. In

※ 도면 중 주요 부분에 대한 부호의 설명※ Explanation of the code for the main part of the drawing

1 : 가스누설감지기 2 : 경보등1: gas leak detector 2: alarm light

3 : 경고음발생기 4 : 정역구동모터3: warning sound generator 4: forward / reverse drive motor

5 : 타이머 6 : 윈도우스위치5: Timer 6: Window Switch

이하 본 발명의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명에 의한 수소자동차의 가스누설시 안전장치를 나타내는 도면으로 도면중 부호1은 수소연료탱크로부터 수소연료가 누설시 이를 감지하는 가스누설감지기이며 이는 가스누설 감지시 회로를 온 접속하는 일종의 스위치이다.1 is a diagram showing a safety device for gas leakage of a hydrogen vehicle according to the present invention. In the drawing, reference numeral 1 denotes a gas leakage detector which detects when a hydrogen fuel leaks from a hydrogen fuel tank. It's a kind of switch.

상기 가스누설감지기(1)의 신호출력시, 즉 가스누설이 감지되어 회로가 스위치 접속되면 전원이 공급되어 운전석에 설치된 경보등(2)과 경고음발생기(3)가 가동되어 운전자는 시각과 청각으로 이를 감지하게 된다.When the gas leakage detector 1 outputs a signal, that is, when gas leakage is detected and the circuit is connected to the switch, power is supplied and the alarm lamp 2 and the warning sound generator 3 installed in the driver's seat are operated so that the driver can visually and acoustically. Will be detected.

그리고 상기 경보등(2)과 경고음발생기(3)와 직렬로 정역구동모터(4)가 회로 접속되어 있으며 그의 도중에는 타이머(5)가 접속되어 있다.In addition, a forward and backward drive motor 4 is connected in series with the alarm lamp 2 and the warning sound generator 3, and a timer 5 is connected in the middle thereof.

상기 정역구동모터(4)는 유리창을 승하강시켜 개폐하기 위한 것으로 도면중 부호6은 유리창을 승하강 시키기 위해 정역구동모터(4)를 정방향 또는 역방향 구동시키기 위한 윈도우스위치이다.The forward and reverse drive motor 4 is to open and close the glass window by raising and lowering the reference numeral 6 in the figure is a window switch for driving the forward and backward drive motor 4 in the forward or reverse direction to raise and lower the glass window.

이상과 같은 본 발명은 가스가 누설되어 가스누설감지기(1)에 의해 감지되어 회로를 온 접속하면 경보등(2)과 경고음발생기(3)가 작동됨과 동시에 타이머(5)에서 일정시간, 예를들면 유리창의 하강에 필요한 시간인 약 1초 내지 3초 동안 정역구동모터(4)를 구동시켜 창문을 자동으로 열게된다.According to the present invention as described above, when the gas leaks and is detected by the gas leakage detector 1 and the circuit is turned on, the alarm lamp 2 and the alarm sound generator 3 are operated, and at the same time, The window is automatically opened by driving the forward and backward drive motor 4 for about 1 to 3 seconds, which is a time required for the lowering of the window.

이에따라 차실내가 환기되므로서 수소가스의 침입에 의한 위험을 방지할 수 있게 되는 것이다.Accordingly, the interior of the vehicle is ventilated to prevent the risk of intrusion of hydrogen gas.

이상과 같은 본 발명에 의하면 수소자동차의 연료계로부터 수소가스가 누설될 경우 경보장치를 가동하여 운전자에게 이를 알려줄 뿐 아니라 유리창을 자동으로 열어주어 실내를 환기시키게 되므로써 가스에 의한 질식이나 화재 등을 예방하게 되어 안정성을 크게 향상시키는 효과가 있다.According to the present invention as described above, when hydrogen gas leaks from the fuel system of a hydrogen vehicle, an alarm device is activated to notify the driver, and the window is automatically opened to ventilate the room, thereby preventing suffocation or fire caused by gas. It is effective to greatly improve the stability.
