이하에서 상기 본 발명의 바람직한 구성예를 첨부도면에 의해 상세히 설명한다.Hereinafter, the preferred configuration of the present invention will be described in detail by the accompanying drawings.

본 발명 주유중 엔진전원차단 장치는 주유구 도어(2) 또는 캡(4)을 개방할 경우 엔진전원을 차단하는 전원차단수단(E)을 갖추어서 된 부분이다.The engine power cut-off device of the present invention is equipped with a power cut-off means (E) for shutting off the engine power when the filling port door 2 or the cap 4 is opened.

도 1은 본 발명에 의한 전원차단수단(E)의 일실시예의 사시도로서, 차체(1)의 일측에 개폐가능하도록 도어(2)가 힌지설치되고, 도어(2)의 내측에는 연료주입을 위한 주유구(3)가 구비되어 캡(4)으로 개폐시키도록 구성되어 있다.1 is a perspective view of one embodiment of the power cut-off means (E) according to the present invention, the door (2) is hinged to be opened and closed on one side of the vehicle body (1), the inside of the door (2) for fuel injection The filling hole 3 is provided, and it is comprised so that it may open and close with the cap 4.

상기 전원차단수단(E)은 도어(2) 내측에 위치하도록 차체(1)에 구비된 브라켓(11)과, 상기 브라켓(11)에 고정설치되어 엔진의 전원을 전기, 회로적으로 차단/인가시키는 스위치(5)와, 상기 도어(2)의 내면에 고정설치되어 개폐작동시에 탄성에 의해 스위치(5)를 온/오프시키는 탄성작동편(6)으로 구성된다.The power cut-off means E is fixed to the bracket 11 provided in the vehicle body 1 so as to be located inside the door 2 and the bracket 11 to cut off / apply the power of the engine electrically and circuitly. And a resilient actuating piece 6 fixed to the inner surface of the door 2 to turn the switch 5 on / off by elasticity during the opening and closing operation.

도 2는 본 발명에 의한 전원차단수단(E)의 다른 실시예시도로서, 차체(1)의 외부로 인출된 주유구(3)의 상단내면에 나사부(31)가 형성되어 캡(4)의 나사부(41)를 체결시켜 주유구(3)가 폐쇄되록 함과 동시에 주유구(3)의 상단이 캡(4)하단의 패킹(42)을 가압하여 연료의 누출이 방지되도록 구성되어 있으며, 캡(4)의 외면에는 주유구(3)외면을 포삽하는 연장부(43)가 형성되어 있다.2 is a view showing another embodiment of the power cut-off means E according to the present invention, in which a screw portion 31 is formed on the upper end inner surface of the oil filling hole 3 drawn out of the vehicle body 1, and thus the screw portion of the cap 4 is formed. (41) is fastened to close the filling hole (3) and at the same time the upper end of the filling hole (3) is configured to pressurize the packing (42) at the bottom of the cap (4) to prevent the leakage of fuel, the cap (4) An extension portion 43 is formed on the outer surface of the oil port 3 to insert the outer surface thereof.

상기 전원차단수단(E)은, 주유구(3)의 외면에 끼움고정되고 그 상면에 접속단자(7a)를 구비한 합성수지재의 접속하판(8)과, 상기 접속하판(8)의 상부에 적층설치되고 그 하면에 접속단자(7b)를 구비한 합성수지재의 접속상판(9)과, 상기 접속상판(9)에 상향 인지력을 부여하도록 접속하판(8)과의 사이에 평면상 등간격으로 압축설치되는 3개의 탄성스프링(10)과, 상기 주유구(3)의 외면에 고정설치되어 접속상판(9)의 상향이동을 제한하는 스톱퍼링(12)으로 구성된다.The power interrupting means (E) is laminated on the connection lower plate (8) of the synthetic resin material, which is fixed to the outer surface of the oil inlet (3) and has a connection terminal (7a) on the upper surface thereof, and the connection lower plate (8) And a compression top plate 9 of a synthetic resin material having a connection terminal 7b on its lower surface and a connection lower plate 8 at equal intervals in a plane such that the connecting lower plate 8 is provided with an upward recognition force. It consists of three elastic springs 10 and a stopper ring 12 fixed to the outer surface of the oil inlet port 3 to limit the upward movement of the connecting upper plate (9).

이와같은 구성의 본 발명 전원차단수단(E)은 도 1에서와 같은 실시예의 경우, 주유를 위해 도어(2)를 개방하게 되면 엔진전원이 차단되어 엔진이 강제정지된다.In the embodiment of the present invention, the power cut-off means (E) in such a configuration, when the door 2 is opened for oiling, the engine power is cut off and the engine is forcibly stopped.

즉, 도어(2)가 폐쇄된 상태에서는 그 내면의 탄성작동편(6)이 차체(1)의 브라켓(11)에 고정된 스위치(5)를 눌러주게 되며, 이경우 스위치(5)는 온 상태로서 엔진으로 가는 전원을 인가 시켜 정상적인 엔진작동상태를 유지할 수 있게 된다.That is, in the state in which the door 2 is closed, the elastic actuating piece 6 on its inner surface presses the switch 5 fixed to the bracket 11 of the vehicle body 1, in which case the switch 5 is in the on state. By applying power to the engine, it is possible to maintain a normal engine operating state.

그러나, 주유를 위해 도어(2)를 개방할 경우에는 도어(2)와 함께 탄성작동편(6)도 회동하여 스위치(5)에 대한 압력을 해지 하게 되므로 엔진으로 가는 전원을 차단된다.However, when the door 2 is opened for oiling, the elastic working piece 6 also rotates together with the door 2 to release the pressure on the switch 5 so that power to the engine is cut off.

그러므로 운전자의 의지와는 무관하게 주유시에는 엔진을 정지시키게 되며, 주유후 도어(2)를 완전히 닫아 주지 않을경우, 탄성편(6)은 스위치(5)를 눌러주지 못하게 된다.Therefore, irrespective of the driver's will, the engine is stopped when refueling. If the door 2 is not completely closed after refueling, the elastic piece 6 cannot press the switch 5.

따라서 주유중 엔진정지에 의해 불 필요한 연료낭비와 매연배출은 방지되며, 도어(2)의 개방에 의한 안전사고 발생우려도 미연에 방지된다.Therefore, unnecessary fuel waste and soot discharge are prevented by stopping the engine during refueling, and even if a safety accident occurs due to the opening of the door 2, it is prevented in advance.

한편, 도 2에서와 같은 제 2실시예의 경우, (가)에서와 같이 주유를 위해 캡(4)을 분리하게 되면, 접속상판(9)은 탄성스프링(10)의 탄성에 의해 상향이동하게 되며 이에 따라 엔진측으로 가는 전원은 접속단자(7a, 7b)의 분리에 의해 차단된다.On the other hand, in the second embodiment as shown in Figure 2, when the cap 4 for oiling as in (a), the connection top plate 9 is moved upward by the elasticity of the elastic spring (10) As a result, power to the engine side is cut off by disconnecting the connection terminals 7a and 7b.

이때 접속상판(9)은 주유구(3)외면에 고정된 스톱퍼링(12)에 의해 상향이동이 제한되므로 분리우려는 해소된다.At this time, the connection top plate (9) is eliminated because the upward movement is limited by the stopper ring 12 fixed to the oil inlet (3) outer surface.

또한, 주유완료후 캡(4)의 나사부(41)를 주유구(3)의 나사부(31)에 맞추어 잠궈주게 되면, 상기 나사부(31, 41)의 결합에 의해 주유구(3)의 상단이 캡(4)의 내부하단에 설치된 패킹(42)을 가압하여 완벽한 기밀상태를 유지되는데, 상기 나사부(31, 41)의 결합이 진행됨에 따라 캡(4)외면에 연장부(43)에 의해 접속상판(9)은 하향이동을 진행하게 된다.In addition, if the screw portion 41 of the cap 4 is locked in accordance with the screw portion 31 of the oil filling hole 3 after the completion of oiling, the upper end of the oil filling hole 3 is closed by the coupling of the screw portions 31 and 41. 4) Pressurize the packing 42 installed at the inner lower end of the airtight state to maintain perfect airtightness, and as the coupling of the screw parts 31 and 41 is progressed, the connection top plate is formed by the extension part 43 on the outer surface of the cap 4. 9) proceeds downward movement.

따라서 캡(4)과 주유구(3)가 완벽히 조립된 상태에서는 접속상판(9)도 최대하향이동한 상태로서 접속단자(7a, 7b)들은 접촉된 상태, 즉 엔진으로 가는 전원회로를 개방한 상태가 된다.Therefore, in the state where the cap 4 and the oil inlet 3 are completely assembled, the connecting top plate 9 is also moved downward, and the connecting terminals 7a and 7b are in contact with each other, that is, the power circuit to the engine is opened. Becomes

이상의 설명에서와 같이 본 발명은 주유시에 엔진의 전원을 자동으로 강제차단시켜 엔진을 정지시키게 되므로 불필요한 연료의 낭비를 막아 경제적 손실 최소화를 도모할 수 있음은 물론, 매연의 배출방지에 의해 환경오염을 줄일 수 있고, 도어(2)또는 캡(4)의 완벽한 폐쇄가 이루어지지 않을 경우 엔진 시동이 걸리지 않으므로 안전사고를 미연에 방지할 수 있는 등의 효과가 있다.As described above, the present invention automatically stops the engine by forcibly turning off the power of the engine when refueling, thereby preventing unnecessary waste of fuel and minimizing economic losses, and preventing pollution of the environment. It is possible to reduce, and since the engine is not started when the door 2 or the cap 4 is not completely closed, there is an effect of preventing a safety accident in advance.
