캡 분실방지를 위한 자동차용 연료주입구 구조{Automobile fuel filler door structure for preventing cap from loss}Automobile fuel filler door structure for preventing cap from loss}

본 발명은 캡 분실방지를 위한 자동차용 연료주입구 구조에 관한 것으로서, 보다 상세하게는 자동차에 연료를 주입한 후 연료캡을 닫지 않고 필라도어를 록킹시켜서 연료캡이 분실되는 사례가 빈번하게 발생되는 바, 이런 경우 연료캡이 닫혀 있지 않으면 연료주입구의 필러도어가 록킹되지 않도록 한 캡 분실방지를 위한 연료주입구 구조에 관한 것이다.The present invention relates to a fuel inlet structure for automobiles to prevent the loss of the cap, more specifically, the case that the fuel cap is frequently lost by locking the pillar door without closing the fuel cap after injecting fuel into the automobile In this case, it relates to a fuel inlet structure for preventing the loss of the cap so that the filler door of the fuel inlet is not locked if the fuel cap is not closed.

일반적으로 자동차에는 연료를 주입하기 위한 연료주입구가 마련되어 있는 바, 연료주입구는 차체의 좌측이나 우측 중 어느 한쪽에 위치되고 연료탱크와 연결된 연료파이프의 입구를 연료캡으로써 밀폐시키고 있으며 그 연료캡이 수용되도록 소정의 공간이 형성되어 있다.Generally, a vehicle is provided with a fuel inlet for injecting fuel. The fuel inlet is located at either the left or right side of the vehicle body and seals the inlet of the fuel pipe connected to the fuel tank by the fuel cap, and the fuel cap is accommodated. The predetermined space is formed so that it may be.

한편, 연료캡이 마련된 연료주입구를 커버하기 위하여 연료주입구에는 록킹장치가 제공되는 필라도어가 힌지회동 가능하게 설치된다.On the other hand, in order to cover the fuel inlet in which the fuel cap is provided, the fuel inlet is provided with a hinged rotatable pillar which is provided with a locking device.

도1은 일반적인 차량의 연료주입구를 나타낸 도면이고, 도2는 종래 연료주입구의 구조를 나타낸 단면도이다.1 is a view showing a fuel inlet of a typical vehicle, Figure 2 is a cross-sectional view showing the structure of a conventional fuel inlet.

도2에서 보면, 자동차 바디에는 소정의 공간이 형성된 연료주입구(10)가 마련되고 연료주입구(10)의 내측에는 연료탱크(미도시)와 연결되어 실질적으로 연료가 주입되는 연료파이프(1)가 마련되며, 상기 연료파이프(1)의 끝단에는 연료캡(2)이 구비된다.Referring to FIG. 2, a fuel inlet 10 having a predetermined space is provided in an automobile body, and a fuel pipe 1 connected to a fuel tank (not shown) inside the fuel inlet 10 to substantially inject fuel therein is provided. A fuel cap 2 is provided at an end of the fuel pipe 1.

또한, 상기 연료캡(2) 및 연료파이프(1)가 마련된 연료주입구(10)를 커버하기 위하여 상기 연료주입구(10)의 최외측에는 필라도어(20)가 마련된다. 상기 필라도어(20)는 그 일측 끝단(20a)이 연료주입구(10)의 내벽에 설치된 힌지브래킷(11)에 힌지(21)를 매개로 회동 가능하게 연결된다.In addition, a pillar door 20 is provided at the outermost side of the fuel inlet 10 to cover the fuel inlet 10 provided with the fuel cap 2 and the fuel pipe 1. One end 20a of the pillar door 20 is rotatably connected to the hinge bracket 11 installed on the inner wall of the fuel inlet 10 via the hinge 21.

여기서, 상기 힌지(21)는 구즈넥(goose neck) 타입으로서 구즈넥 타입의 힌지는 차체(10a)의 굴곡이 심하여 힌지 회전축(21a)을 필라도어(20) 상에 위치시킬 수 없거나 필라도어(20)의 형상이 원형일 때 주로 사용된다.Here, the hinge 21 is a goose neck type, and the goose neck type hinge has a severe curvature of the vehicle body 10a so that the hinge rotation shaft 21a cannot be positioned on the pillar door 20 or the pillar door 20 is used. It is mainly used when the shape of is circular.

또한, 상기 힌지(21)와 접촉되는 힌지브래킷(11)의 일측에는 팝업스프링(12)이 설치되어 있는데, 이 팝업스프링(12)은 상기 필라도어(20)가 닫힐 때 팝업스프링(12) 쪽으로 접근하는 힌지(21)에 의해 변형되어 탄성반발력이 저장된다. 즉, 상기 필라도어(20)에 가해지던 외력이 제거되면 상기 팝업스프링(12)의 탄성반발력이 힌지(21)에 전달되어 상기 필라도어(20)가 개방된다.In addition, one side of the hinge bracket 11 in contact with the hinge 21 is provided with a pop-up spring 12, the pop-up spring 12 toward the pop-up spring 12 when the pillar 20 is closed. It is deformed by the approaching hinge 21 to store the elastic repulsive force. That is, when the external force applied to the pillar door 20 is removed, the elastic repulsive force of the pop-up spring 12 is transmitted to the hinge 21 to open the pillar door 20.

한편, 상기 힌지(21)가 연결된 상기 필라도어(20) 일측의 반대쪽인 필라도어 타측(20b)에는 연료주입구의 걸림수단(13)에 걸리는 걸림부(22)가 형성되어 있다.On the other hand, the engaging portion 22 is caught on the locking means 13 of the fuel injection hole on the other side of the pillar door 20b opposite to one side of the pillar door 20 to which the hinge 21 is connected.

따라서, 상기 필라도어의 타측(20b)에 형성된 걸림부(22)가 상기 연료주입구 걸림수단(13)에 걸리는 걸림력은 상기 팝업스프링(12)이 필라도어의 힌지(21)에 가해지는 힘과 평형을 이룬다.Accordingly, the locking force of the locking portion 22 formed on the other side 20b of the pillar door to the fuel injection hole locking means 13 is determined by the force applied by the pop-up spring 12 to the hinge 21 of the pillar door. Equilibrate.

또한, 상기 필라도어(20)의 타측 끝단에는 필라도어(20)가 닫힐 때 차체(10a)와 충돌됨으로써 받게 되는 충격을 줄이기 위해 고무재질의 충격흡수부재(23)가 설치된다.In addition, the other end of the pillar door 20 is provided with a rubber shock absorbing member 23 to reduce the impact received by colliding with the vehicle body 10a when the pillar door 20 is closed.

이때, 상기 필라도어(20)는 그 타측 끝단이 차체(10a)와의 사이에서 일정한 갭을 유지하여야만 필라도어(20)가 차체(10a)에 걸리지 않고 자유롭게 회동될 수있다.At this time, the pillar door 20 may be freely rotated without the hooker 20 being caught by the vehicle body 10a only when the other end thereof maintains a constant gap between the vehicle body 10a.

그러나 이상에서와 같은 종래의 연료주입구를 갖는 차량은 주유소에서 연료를 주입하고 난 후 주유원이 실수로 연료캡을 닫지 않은 채로 필라도어만을 닫고 보내는 경우가 종종 발생하여 연료캡을 분실하는 문제점이 생긴다.However, a vehicle having a conventional fuel injection port as described above often causes a problem that the fuel source is lost after the fuel source accidentally closes the filament without closing the fuel cap after injecting fuel from the gas station.

이는 또한 연료캡의 분실 문제로만 끝나는 것이 아니라 개방된 연료파이프를 통해 연료가 기화되어 대기로 방출되므로 심각한 대기 오염을 일으키게 된다. 연료캡을 닫지 않으면 연료는 기화하여 대기중으로 방출되는데, 특히 가솔린과 같은 연료는 그 휘발도가 매우 높아 더운 여름철에는 대기중으로 다량 방출되므로 심각한 대기오염을 초래하는 문제점이 있다.It also does not end only with the loss of the fuel cap but also causes serious air pollution as the fuel is vaporized and released into the atmosphere through the open fuel pipe. If the fuel cap is not closed, the fuel is vaporized and released into the atmosphere. Particularly, a fuel such as gasoline has a high volatility, and thus a large amount of air is released into the atmosphere in the hot summer season, thereby causing serious air pollution.

본 발명은 상술한 바와 같은 문제점을 해결하기 위하여 제안된 것으로서, 그 목적은 연료필라도어가 연료캡의 유무를 감지하여 연료캡이 닫혀 있지 않으면 필라도어가 록킹되지 않도록 구성함으로써 주유가 끝난 후 설사 연료캡을 닫지 않는 실수를 하더라도 이 사실을 주유하는 사람이 인식하도록 하여 캡의 분실을 방지하도록 하는데 있다.The present invention has been proposed in order to solve the above problems, the object of the fuel pillar is to detect the presence or absence of the fuel cap is configured so that the pillar is not locked if the fuel cap is not closed, diarrhea after the end of fueling Even if you make a mistake not to close the cap, it is to make the person who recognizes this fact to prevent the loss of the cap.

이상의 도면을 참고하여 본 발명의 구성을 설명하면, 자동차의 차체 일측에는 소정의 공간을 갖는 연료주입구(10)가 형성되어 있고, 상기 연료주입구(10)에는 주유건(미도시)이 끼워져 연료가 주입되는 연료파이프(1)가 설치되어 있다.Referring to the configuration of the present invention with reference to the drawings, the fuel inlet 10 having a predetermined space is formed on one side of the vehicle body, the fuel injection port 10 is fitted with a fuel injection gun (not shown) to the fuel The fuel pipe 1 to be injected is provided.

상기 연료파이프(1)의 끝단에는 연료가 증발되는 것과 기타 이물질이 연료파이프(1)를 통해 연료탱크(미도시) 내부로 들어가는 것을 방지하기 위하여 연료파이프(1)에 돌려 끼워지는 연료캡(2)이 구비되며, 상기 연료파이프(1)와 연료캡(2)이 차량 외부에서 보이지 않도록 커버하는 필라도어(20)가 힌지(21)를 매개로 회동 가능하게 차체(10a)에 설치된다.At the end of the fuel pipe (1) fuel cap (2) is screwed into the fuel pipe (1) to prevent the fuel from evaporating and other foreign matter entering the fuel tank (not shown) through the fuel pipe (1) Is provided, and the pillar door 20 which covers the fuel pipe 1 and the fuel cap 2 from being visible from the outside of the vehicle is installed on the vehicle body 10a so as to be rotatable through the hinge 21.

또한, 상기 연료주입구(10)가 형성된 차체(10a)의 일측에는 상기 필라도어(20)를 록킹시키기 위한 걸림수단(13)이 설치되는데, 상기 걸림수단(13)은 케이블(미도시)이나 커넥팅로드(미도시)를 매개로 차실내에 위치되는 작동버튼(미도시) 또는 릴리즈레버(미도시)와 연결되어 필라도어(20)의 록킹을 해제하게 된다.In addition, a locking means 13 for locking the pillar door 20 is installed at one side of the vehicle body 10a on which the fuel injection hole 10 is formed, and the locking means 13 is a cable (not shown) or connecting. It is connected to an operation button (not shown) or a release lever (not shown) positioned in the vehicle via a rod (not shown) to release the lock 20.

한편, 상기 걸림수단(13)에 인접하는 필라도어(20)의 내면 일측에는 마운팅브래킷(30)이 고정 설치되는데, 상기 마운팅브래킷(30)에는 상기 연료캡(2) 쪽을 향해 돌출되는 슬라이더(31)가 상기 걸림수단(13) 측 방향으로 슬라이딩 가능하도록 끼워진다.On the other hand, the mounting bracket 30 is fixed to one side of the inner surface of the pillar door 20 adjacent to the locking means 13, the mounting bracket 30 is a slider protruding toward the fuel cap (2) ( 31 is fitted to slide in the direction of the locking means (13).

상기 슬라이더(31)가 마운팅브래킷(30)에 슬라이딩 가능하게 끼워지는 구조는 도5에 잘 나타나 있는데, 여기에 도시된 바와 같이, 마운팅브래킷(30)의 일측에는 가이드레일부(30a)가 형성되고, 상기 슬라이더(31)에는 상기 가이드레일부(30a)를 따라 슬라이딩될 수 있도록 가이드홈(31a)이 형성되어 있다.The structure in which the slider 31 is slidably fitted to the mounting bracket 30 is well illustrated in FIG. 5. As shown here, a guide rail portion 30a is formed at one side of the mounting bracket 30. In addition, the slider 31 is formed with a guide groove 31a to slide along the guide rail portion 30a.

또한, 상기 슬라이더(31)는 상기 연료캡(2)에 의하여 밀려서 상기 걸림수단(13) 쪽으로 슬라이딩될 수 있도록 상기 연료캡(2)과 접촉되는 일측 부위에는 경사면(31b)이 형성된다.In addition, the slider 31 is inclined surface 31b is formed on one side contact with the fuel cap 2 so that the slider 31 is pushed by the fuel cap 2 and slide toward the locking means 13.

그리고, 상기 연료캡(2)에 밀려서 걸림수단(13) 쪽으로 슬라이딩된 후 상기 걸림수단(13)에 걸릴 수 있도록 상기 슬라이더에는 소정의 걸림공(31c)이 형성된다.In addition, a predetermined locking hole 31c is formed in the slider so as to be caught by the locking means 13 after being pushed by the fuel cap 2 and sliding toward the locking means 13.

여기서, 슬라이더(31)에 형성되는 상기 걸림공(31c)은 상기 걸림수단(13)의 캐치부(13a)와 서로 일직선을 이루도록 형성되어야 한다.Here, the locking hole 31c formed in the slider 31 should be formed in a line with the catch portion 13a of the locking means 13.

또한, 상기 슬라이더(31)는 상기 마운팅브래킷(30) 상에 탄성부재(32)를 매개로 탄력적으로 설치됨으로써 상기 슬라이더(31)에 걸림수단(13) 쪽을 향하여 가해지는 외력이 제거되면 상기 슬라이더(31)는 탄성부재(32)의 탄성력에 의하여 다시 연료캡(2)과 접촉되는 위치로 복귀되어, 상기 슬라이더의 걸림공(31c)이 상기걸림수단의 캐치부(13a)에 걸리지 않게 된다.In addition, the slider 31 is elastically installed on the mounting bracket 30 via the elastic member 32, so that the slider is removed when the external force applied toward the locking means 13 toward the slider 31 is removed. 31 is returned to the position in contact with the fuel cap 2 again by the elastic force of the elastic member 32, so that the engaging hole 31c of the slider is not caught by the catch portion 13a of the locking means.

즉, 상기 슬라이더(31)는 연료캡(2)에 의하여 상기 걸림수단(13) 쪽으로 밀려서 슬라이더의 걸림공(31c)이 상기 걸림수단의 캐치부(13a)에 걸리게 되므로 필라도어(20)가 록킹되며, 만일 상기 연료캡(2)이 연료파이프(1)에 결합되어 있지 않다면 도4에 나타낸 바와 같이 상기 슬라이더(31)에 걸림수단(13) 쪽으로 미는 외력이 가해지지 않으므로 슬라이더(31)는 탄성부재(32)의 탄성력에 의하여 슬라이더(31)의 걸림공(31c)이 상기 캐치부(13a)에 걸리지 않는 위치에 있게 되는 것이다. 따라서, 이때는 상기 필라도어(20)가 록킹되지 않는다.That is, the slider 31 is pushed toward the catching means 13 by the fuel cap 2 so that the catching hole 31c of the slider is caught by the catching portion 13a of the catching means. If the fuel cap 2 is not coupled to the fuel pipe 1, as shown in FIG. 4, the external force pushing toward the locking means 13 is not applied to the slider 31 so that the slider 31 is elastic. By the elastic force of the member 32, the engaging hole 31c of the slider 31 is in a position not caught by the catch portion 13a. Therefore, the pillar door 20 is not locked at this time.

결국, 연료캡(2)이 연료파이프(1)에 결합되어 있지 않으면 상기 필라도어(20)가 록킹되지 않으므로 주유하는 사람은 연료캡(2)이 없는 것을 금방 인지할 수 있게 되고, 이로 인하여 연료캡(2)의 분실 사실을 알지 못한 채로 필라도어(20)만 닫고 주행하는 일은 사라지게 될 것이다.As a result, if the fuel cap 2 is not coupled to the fuel pipe 1, the pillar door 20 is not locked, and thus the fueling person can immediately recognize that the fuel cap 2 is not present, and thus the fuel Without knowing that the cap 2 is lost, the driving of only the filament 20 will be lost.

상술한 바와 같이 본 발명에 따른 캡 분실방지를 위한 자동차용 연료주입구 구조에 의하면, 주유가 끝난 뒤 실수로 연료캡을 닫지 않고 필라도어를 닫아도 본 발명의 슬라이더에 의하여 필라도어가 록킹되지 않으므로 주유원이 연료캡의 유무를 인식할 수 있어 연료캡의 분실을 방지할 수 있는 효과가 있다.As described above, according to the fuel inlet structure for automobiles to prevent the loss of the cap according to the present invention, even if the filler is not accidentally closed after closing the fuel cap, the filler is not locked by the slider of the present invention. Recognize the presence or absence of the fuel cap has the effect of preventing the loss of the fuel cap.
