본 발명은 자동차 연료공급 제어장치에 관한 것으로서, 더욱 상세하게는 자동차 충돌사고 발생시 연료공급관의 소정위치에 설치된 연료펌프를 역회전시켜 상기 연료공급관 내부에 남아있는 연료를 연료탱크로 역류시키므로서 충돌에 의한 연료공급계통의 파손으로 발생하는 누유를 방지할 수 있는 자동차 연료공급 제어장치에 관한 것이다.The present invention relates to a vehicle fuel supply control device, and more particularly, in the event of an automobile collision, a fuel pump installed at a predetermined position of a fuel supply pipe is reversely rotated so that the fuel remaining inside the fuel supply pipe is returned to the fuel tank so as to prevent a collision. The present invention relates to a vehicle fuel supply control device capable of preventing leakage caused by breakage of the fuel supply system.
일반적으로 연료탱크에 저장되어 있는 연료는 연료공급관의 소정위치에 설치된 연료펌프의 회전에 의해 상기 연료공급관을 따라 엔진으로 공급된다.In general, the fuel stored in the fuel tank is supplied to the engine along the fuel supply pipe by the rotation of the fuel pump installed at a predetermined position of the fuel supply pipe.
제1도는 종래의 자동차 연료 공급장치의 개략적인 구성을 나타낸 것이다. 연료주입구(11)를 통해 주입된 연료는 연료탱크(10) 내에 일시 저장되었다가 자동차가 시동되면 연료여과망(12)에서 불순물이 제거된 후, 연료펌프(14)의 회전에 의해 연료공급관(13)을 따라 분사기(15)로 공급되어 엔진(16) 내부로 분사된다.1 shows a schematic configuration of a conventional automobile fuel supply device. Fuel injected through the fuel inlet 11 is temporarily stored in the fuel tank 10, and when the vehicle is started, impurities are removed from the fuel filtration network 12, and then the fuel supply pipe 13 is rotated by the rotation of the fuel pump 14. ) Is supplied to the injector 15 and injected into the engine 16.
그러나, 상기와 같은 구성을 갖는 종래의 자동차 연료 공급장치는 충돌사고 발생시에도 연료펌프(14)가 계속 회전하여 연료탱크(10) 내의 연료를 연료공급관(13)을 통해 엔진(16)으로 공급함에 따라 충돌사고로 인하여 연료공급계통이 파손된 경우에는 연료가 외부로 누유되어 화재가 발생하는 경우가 있었다.However, in the conventional vehicle fuel supply device having the above configuration, even when a collision accident occurs, the fuel pump 14 continuously rotates to supply fuel in the fuel tank 10 to the engine 16 through the fuel supply pipe 13. As a result, when the fuel supply system is damaged due to a crash, fuel may leak to the outside, causing a fire.
본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 개발된 것으로서, 본 발명의 목적은 자동차 충돌사고 발생시 연료탱크로부터 엔진으로의 연료공급을 차단할 뿐만 아니라 연료펌프를 역회전시켜 연료공급관내에 남아있는 연료를 연료탱크로 역류시켜 충돌시 연료의 누유로 인한 화재를 방지하도록 한 것이다.The present invention was developed to solve the above conventional problems, the object of the present invention is not only to shut off the fuel supply from the fuel tank to the engine in the event of an automobile crash, but also to rotate the fuel pump to remain in the fuel supply pipe The fuel was flowed back into the fuel tank to prevent fire from fuel leakage in the event of a collision.
상기와 같은 목적을 달성하기 위하여 본 발명은, 연료공급관의 소정위치에 설치되어 상기 공급관내의 연료압력의 변화를 검출하는 연료압력센서와, 상기 연료압력센서의 출력에 따라 스위칭되는 트랜지스터와, 상기 트랜지스터의 스위칭 동작에 따라 상기 연료공급관의 소정위치에 설치된 연료펌프를 정/역회전 시키는 릴레이 스위치를 구비하여 연료공급계통의 파손으로 인한 연료의 누유를 방지하도록 된 것을 특징으로 한다.In order to achieve the above object, the present invention is a fuel pressure sensor which is installed at a predetermined position of the fuel supply pipe for detecting a change in the fuel pressure in the supply pipe, a transistor switched in accordance with the output of the fuel pressure sensor, and In accordance with the switching operation of the transistor is provided with a relay switch for forward / reverse rotation of the fuel pump installed in a predetermined position of the fuel supply pipe characterized in that to prevent the leakage of fuel due to damage to the fuel supply system.
이하에서는 첨부된 도면을 참조하여 본 발명의 바람직한 일실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention;
제2도는 연료공급관과 연료압력센서의 연결구조를 나타낸 것이며, 제3도는 본 발명에 따른 자동차 연료공급 제어장치의 구성을 나타낸 것이다.2 shows a connection structure between a fuel supply pipe and a fuel pressure sensor, and FIG. 3 shows a configuration of a vehicle fuel supply control apparatus according to the present invention.
본 발명의 장치는 제2도에 도시된 바와 같이 연료공급관의 소정위치에 설치되어 충돌사고로 인한 연료공급관의 파손에 따른 상기 공급관 내의 연료압력의 변화를 검출하는 연료압력센서(17)와, 상기 연료압력센서(17)의 출력에 따라 스위칭되는 트랜지스터(TR)와, 상기 트랜지스터(TR)의 스위칭 동작에 따라 스위칭되어 상기 연료공급관(13)의 소정위치에 설치된 연료펌프(14)를 정/역회전 시키는 릴레이 스위치(REL1,REL2)로 구성된다.The apparatus of the present invention includes a fuel pressure sensor 17 installed at a predetermined position of the fuel supply pipe as shown in FIG. 2 and detecting a change in fuel pressure in the supply pipe due to a breakdown of the fuel supply pipe due to a collision accident. The transistor TR, which is switched in accordance with the output of the fuel pressure sensor 17, and the fuel pump 14, which is switched in accordance with the switching operation of the transistor TR, is installed at a predetermined position of the fuel supply pipe 13, is reversed. It consists of relay switches REL1 and REL2 to rotate.
초기상태에서 상기 릴레이 스위치(REL1,REL2)는 각각 접점(b,b')에 접속되어 있다.In the initial state, the relay switches REL1 and REL2 are connected to the contacts b and b ', respectively.
상기와 같이 구성된 본 발명의 작용효과를 설명한다.It demonstrates the effect of the present invention configured as described above.
자동차가 정상 주행시 연료공급관(13)은 파손되지 않았으므로 연료압력센서(17)는 연료압력의 변화를 검출하지 못한다. 따라서 상기 연료압력센서(13)는 로우신호를 출력하고, 이에따라 트랜지스터(TR)는 턴오프된다.Since the fuel supply pipe 13 is not broken when the vehicle is normally driven, the fuel pressure sensor 17 does not detect the change in the fuel pressure. Therefore, the fuel pressure sensor 13 outputs a low signal, and accordingly, the transistor TR is turned off.
상기 트랜지스터(TR)가 턴오프되면, 릴레이 코일(L)에는 전류가 인가되지 않으므로 릴레이 코일(L) 주위에는 자장이 형성되지 않는다. 따라서 릴레이 스위치(REL1,REL2)가 초기상태를 유지함에 따라 전류가 I1 방향으로 흘러 연료펌프(14)를 정회전시켜 연료탱크(10) 내의 연료를 엔진(16)으로 공급한다.When the transistor TR is turned off, no current is applied to the relay coil L so that no magnetic field is formed around the relay coil L. Therefore, as the relay switches REL1 and REL2 maintain the initial state, current flows in the direction I1 to rotate the fuel pump 14 forward to supply the fuel in the fuel tank 10 to the engine 16.
그러나, 자동차 충돌사고가 발생하여 연료공급계통에 이상이 발생하면 상기 연료압력센서(17)가 이를 검출하여 하이신호를 출력한다. 따라서 트랜지스터(TR)은 턴온되어 릴레이 코일(L)에 전류가 인가된다.However, when an automobile collision accident occurs and an abnormality occurs in the fuel supply system, the fuel pressure sensor 17 detects this and outputs a high signal. Accordingly, the transistor TR is turned on to apply a current to the relay coil L. FIG.
상기 릴레이 코일(L)에 전류가 인가되면, 릴레이 코인(L) 주변에는 자장이 형성되고, 이에따라 릴레이 스위치(REL1,REL2)가 접점(a,a')에 접속되어 전류는 I2 방향으로 흐르게 된다.When a current is applied to the relay coil L, a magnetic field is formed around the relay coin L. Accordingly, the relay switches REL1 and REL2 are connected to the contacts a and a 'so that the current flows in the I2 direction. .
따라서, 연료탱크(10) 내의 연료가 엔진으로 공급되지 않을 뿐만 아니라 연료공급관(13) 내에 남아있는 연료도 연료탱크(10)로 역류하여 연료탱크내에 저장된다.Therefore, not only the fuel in the fuel tank 10 is not supplied to the engine, but also the fuel remaining in the fuel supply pipe 13 is flowed back to the fuel tank 10 and stored in the fuel tank.
상기와 같이 본 발명은 자동차 충돌사고 발생시 연료탱크와 엔진 사이를 연결하는 연료공급관의 소정의 위치에 설치된 연료펌프를 역회전시켜 연료공급관 내부에 남아있는 연료를 연료탱크로 역류시키므로서 충돌에 의한 연료공급계통의 파손으로 발생하는 연료의 누유를 방지하는 효과가 있다.As described above, the present invention reverses the rotation of the fuel pump installed at a predetermined position of the fuel supply pipe connecting the fuel tank and the engine in the event of an automobile collision to reverse the fuel remaining inside the fuel supply pipe to the fuel tank, thereby causing the fuel to crash. There is an effect of preventing the leakage of fuel caused by breakage of the supply system.
