Description

자동차 연료탱크의 연료캡구조{Fuel cap of fuel tank}Fuel cap structure of automobile fuel tank

본 발명은 연료탱크의 연료캡구조에 관한 것으로, 보다 상세하게는 자동차의연료탱크 주입구에 형성되는 밀폐링의 내구성을 증대하고, 주유구의 밀폐력을 향상하기 위한 자동차 연료탱크의 연료캡구조에 관한 것이다.The present invention relates to a fuel cap structure of a fuel tank, and more particularly to a fuel cap structure of a vehicle fuel tank for increasing the durability of the sealing ring formed in the fuel tank inlet of the vehicle, and to improve the sealing force of the filling port. .

일반적으로 자동차의 일측면에는 연료탱크가 탑재되는데, 상기 연료탱크는 자동차의 차종 및 크기에 따라서 그 용량을 달리하고 있다. 그리고 승용차 및 버스의 경우에는 미관상 연료탱크가 사이드 패널의 내측으로 형성되고, 화물자동차의 경우에는 차체의 일측면에 형성된다. 상기와 같이 연료탱크의 크기 및 설치위치는 차종에 따라 여러형태로 형성되지만 그 근본적이 구조는 비슷하게 형성된다.In general, a fuel tank is mounted on one side of a vehicle, and the fuel tank varies in capacity depending on the type and size of the vehicle. In the case of passenger cars and buses, the aesthetic fuel tank is formed inside the side panel, and in the case of a freight car, it is formed on one side of the vehicle body. As described above, the size and the installation position of the fuel tank are formed in various forms according to the vehicle type, but the basic structure is similarly formed.

즉, 연료가 저장되는 저장공간이 형성되며, 상기 저장공간에 연료를 주입하기 위한 주유구가 형성되고, 상기한 주유구를 막기 위한 연료캡 등으로 구성되는 것이다.That is, a storage space for storing fuel is formed, and an oil filling hole for injecting fuel into the storage space is formed, and a fuel cap for blocking the oil filling hole is formed.

도 5는 종래의 일반적인 연료캡의 장착모습을 도시한 도면으로, 연료탱크(1)의 주유구(2) 외주연과 연료캡(3)의 내주연으로 나사결합이 가능하도록 각각 암나사와 수나사가 형성된다. 그런데 상기와 같이 형성되는 연료캡의 경우에는 연료캡의 분실이 자주발생되므로서 연료가 누출되고, 대기를 오염시키게 되는 문제가 있었다.FIG. 5 is a view illustrating a conventional mounting method of a fuel cap, and a female screw and a male screw are respectively formed to be screwed into an outer circumferential edge of the fuel tank 1 and an inner circumference of the fuel cap 3. do. However, in the case of the fuel cap formed as described above, there is a problem in that fuel is leaked and the air is polluted due to frequent loss of the fuel cap.

상기와 같은 문제점을 보완하기 위해 도 6과 같이 주유구에 일측에 제1캡부재가 형성되고, 다른 일측에 제2캡부재가 형성되어 상기 제1캡부재를 고정하게 되므로서, 연료탱크 내의 연료의 누유를 최대한 방지하며 연료캡이 분실될 염려가 없는 연료캡이 제공되고 있다.In order to compensate for the above problems, as shown in FIG. 6, the first cap member is formed at one side of the filling port, and the second cap member is formed at the other side to fix the first cap member. Fuel caps are provided to prevent leakage and to prevent the loss of fuel caps.

즉, 상기한 제1캡부재(20)는 주유구(14)의 일측에 돌출형성된 한쌍의 제1암힌지(22)와, 제1암힌지(22) 사이에 끼워져 제1고정핀(24)으로 고정되는데 제1수힌지(26)가 하부로 돌출되면서 상면에는 걸림턱(28)이 형성된 제1연료캡(32)으로 이루어진다. 상기 제1연료캡(25)는 제1고정핀(24)을 중심으로 회전된다.That is, the first cap member 20 is sandwiched between the pair of first arm hinges 22 and the first arm hinges 22 protruding from one side of the oil inlet 14 to the first fixing pin 24. The first water hinge 26 is fixed while being protruded downward, and is formed of a first fuel cap 32 having a locking jaw 28 formed thereon. The first fuel cap 25 is rotated about the first fixing pin 24.

상기한 제2부재(30)는 상기 주유구(14)의 다른 일측에 돌출된 한쌍의 제2암힌지(32)와 제2연료캡(35) 사이에 끼워져 제2고정핀(34)으로 고정되도록 제2수힌지(36)가 하부로 돌출된 제2연료캡(32)으로 이루어진다. 상기 제2연료캡(35)은 제1연료캡(25)에 고정되어 2차적인 기밀유지를 하는 역할을 하게 된다. 그리고 상기한 주유구(14) 끝단에는 기밀을 유지하기 위한 밀폐링(40)이 장착된다.The second member 30 is sandwiched between the pair of second arm hinges 32 and the second fuel cap 35 protruding from the other side of the oil inlet 14 so as to be fixed by the second fixing pin 34. The second male hinge 36 is formed of a second fuel cap 32 protruding downward. The second fuel cap 35 is fixed to the first fuel cap 25 and serves to maintain secondary hermeticity. And the end of the filling hole 14 is equipped with a sealing ring 40 for maintaining the airtight.

이와 같은 연료캡구조는 연료탱크(10) 내의 수납실(12)에 보관되어 있는 연료가 누유되는 것을 방지하기 위해 1차적으로 상기 제1캡부재(20)로 주유구(14)를 폐쇄하면서 2차적으로 제2캡부재(20)를 고정함에 다라 충분한 기밀 유지로 연료의 누유를 방지할 수 있게 된다.Such a fuel cap structure is secondary by closing the filling port 14 with the first cap member 20 to prevent leakage of fuel stored in the storage chamber 12 in the fuel tank 10. As a result of fixing the second cap member 20, it is possible to prevent leakage of fuel with sufficient airtightness.

그러나 상기와 같이 형성되는 연료캡의 경우에는 제1연료캡이 제1고정핀을 중심으로 회전운동만 하기 때문에 제1연료캡은 주유구에 일시에 전면접촉이 되지 않고 외주면 하부에서 1차적으로 국부 접촉되기 때문에 밀폐링이 밀려 변형되고 개구부의 완벽한 밀폐가 될 수 없어 누유의 위험이 있고 밀폐링의 내구성도 떨어져 쉽게 마모 및 파손되는 문제점이 있었다.However, in the case of the fuel cap formed as described above, since the first fuel cap only rotates around the first fixing pin, the first fuel cap is not directly brought into front contact with the filling port at the time, but is primarily in contact with the lower part of the outer circumferential surface. Therefore, the sealing ring is pushed and deformed, and the opening may not be completely sealed, so there is a risk of leakage of oil, and the durability of the sealing ring is also reduced, causing wear and breakage.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위해서 안출된 것으로서, 자동차의 연료탱크 주유구에 형성되는 밀폐링의 내구성을 증대하고, 주유구의 밀폐력을 향상하기 위한 자동차 연료탱크의 연료캡구조를 제공하는 데 목적이 있는 것이다.Accordingly, the present invention has been made to solve the above problems, to provide a fuel cap structure of the vehicle fuel tank for increasing the durability of the sealing ring formed in the fuel tank filling port of the vehicle, and to improve the sealing force of the filling port. There is a purpose.

본 발명은 상기와 같은 목적을 달성하기 위한 수단으로서,The present invention as a means for achieving the above object,

주유구의 일측면에 제1캡부재가 힌지에 의해 결합되고, 주유구의 다른 일측으로 제2캡부재가 힌지에 의해 결합되어, 제1연료캡을 닫은 후에 제2연료캡으로써 상기 제1연료캡을 고정시키도록 형성되는 연료캡에 있어서,The first cap member is coupled to one side of the filling hole by a hinge, and the second cap member is coupled to the other side of the filling hole by a hinge, and after closing the first fuel cap, the first fuel cap is opened as a second fuel cap. In the fuel cap is formed to be fixed,

상기한 제1캡부재가 회동되며 주유구의 길이방향으로 직선운동이 가능하도록 제1수힌지에 슬롯 홀이 소정길이를 갖는 장공형상으로 형성되어, 상기한 제1캡부재를 회동시켰을 경우에 제1연료캡의 내측면이 주유구 상단에 안착되는 밀폐링에 전면 접촉되는 것을 특징으로 한다.When the first cap member is rotated and the slot hole is formed in a long hole shape having a predetermined length in the first male hinge to enable linear movement in the longitudinal direction of the filling hole, the first cap member is rotated when the first cap member is rotated.

The first cap member 20 is formed on one side of the oil inlet 14 to seal the upper end of the oil inlet 14 as in the prior art, and the other side is provided with a first cap member 20 for fixing the first cap member 20. Two cap member 30 is formed. In addition, a first arm hinge 22 is formed at one side of the outer circumference of the oil filling hole 14 so that the first cap member 20 and the second cap member 30 are mounted. Hinges 32 are formed.

상기한 제1캡부재(20)는 상기 주유구(14)의 일측으로 돌출된 제1암힌지(22)에 끼워지기 위한 제1수힌지(26)와, 그 상면에는 걸림턱(28)이 형성된 제1연료캡(25)으로 이루어진다. 또한, 상기한 제2캡부재(30)는 상기 주유구(14)의 다른 일측에 돌출된 제2암힌지(32)에 끼워지기 위한 제2수힌지(36)와 상기 제1연료캡(25)을 고정하기 위한 제2연료캡(35)으로 이루어진다.The first cap member 20 has a first male hinge 26 to be fitted to the first female hinge 22 protruding to one side of the oil filling hole 14, and a locking jaw 28 is formed on an upper surface thereof. It consists of a first fuel cap (25). In addition, the second cap member 30 has a second male hinge 36 and the first fuel cap 25 to be fitted to the second arm hinge 32 protruding from the other side of the oil inlet 14. It consists of a second fuel cap 35 for fixing the.

즉, 상기한 제1캡부재(20)에 형성되는 제1수힌지(26)가 상기 제1암힌지(22)에 제1고정핀(24)으로써 힌지결합되며, 제2캡부재(30)에 형성되는 제2수힌지(36)가 제2암힌지(32)에 제2고정핀(34)으로써 힌지결합된다.That is, the first male hinge 26 formed on the first cap member 20 is hinged to the first female hinge 22 by the first fixing pin 24, and the second cap member 30 is coupled to the first female hinge 22. The second male hinge 36 formed at the hinge is coupled to the second female hinge 32 by the second fixing pin 34.

상기와 같이 연료캡의 일반적인 구성은 종래와 같이 형성된다. 특히, 본 발명에서는 상기한 제1수힌지(26)의 중간부에는 제1고정핀(24)이 끼워지기 위한 슬롯 홀(50)이 형성된다. 상기한 슬롯 홀(50)은 상기한 제1캡부재(20)이 회동될 뿐만 아니라 주유구(14)의 길이방향으로 직선운동될 수 있도록 하기 위한 것이다.As described above, the general configuration of the fuel cap is formed as in the prior art. In particular, in the present invention, a slot hole 50 for fitting the first fixing pin 24 is formed in the middle portion of the first male hinge 26. The slot hole 50 is for allowing the first cap member 20 to rotate as well as to linearly move in the longitudinal direction of the filling hole 14.

또한, 상기한 주유구(14)의 끝단에는 밀폐링(40)이 종래와 같이 형성된다.In addition, the sealing ring 40 is formed at the end of the filling port 14 as in the prior art.

이상과 같이 형성되는 본 발명의 작동을 설명하면 다음과 같다.Referring to the operation of the present invention formed as described above are as follows.

연료탱크(10)에 연료를 주입하기 위해서는 운전자나 주유자가 연료캡을 열어야 하는데, 이때 우선 상기 제2캡부재(30)를 상측으로 제쳐서 제1캡부재(10)의 일측을 해제시킨다. 그런 다음 상기한 제1캡부재(20)를 아래로 회동시켜 주유구(14)의 입구를 개방시킨 다음, 주유자는 주유건을 상기 주유구의 입구에 넣어 연료를 충전하면 된다.In order to inject fuel into the fuel tank 10, the driver or the lubricator must open the fuel cap. At this time, the second cap member 30 is lifted upward to release one side of the first cap member 10. Then, the first cap member 20 is rotated downward to open the inlet of the oil inlet 14, and the oiler may fill the fuel in the inlet of the oil inlet.

연료의 충전이 끝난 다음에 연료캡을 닫기 위해서는 우선 상기한 제1연료캡(20)을 상측으로 회동시키는데, 이때 상기 제1캡부재(20)는 슬롯 홀(50)에 의해서 주유구(14)의 직선방향으로 이동이 가능하므로, 주유자는 제1연료캡(25)을 뒤로 약간 당긴 다음에 제1연료캡(25)의 내측면의 전면이 상기한 밀폐링(40)의 전면에 접촉되도록 한다.In order to close the fuel cap after the filling of the fuel, the first fuel cap 20 is first rotated upward. In this case, the first cap member 20 is formed by the slot hole 50 of the filling hole 14. Since the linear movement is possible, the lubricator pulls the first fuel cap 25 back slightly so that the front surface of the inner surface of the first fuel cap 25 contacts the front surface of the sealing ring 40.

따라서 연료캡이 닫히는 과정에서 밀폐링(40)의 전둘레에 골고루 가압력이 작용되므로서 밀폐링(40)이 마모 및 손상되는 것이 방지되어 내구성이 증가하게 된다.Therefore, since the pressing force is evenly applied to the entire circumference of the sealing ring 40 in the process of closing the fuel cap, the sealing ring 40 is prevented from being worn and damaged, thereby increasing durability.

제1캡부재(20)를 닫은 후에는 상기 제2캡부재(30)를 하측으로 제쳐서 상기 제1캡부재(20)를 고정시키면 된다.After the first cap member 20 is closed, the first cap member 20 may be fixed by removing the second cap member 30 downward.

상기와 같이 주유구의 일측에 힌지결합되는 제1캡부재의 힌지부에 슬롯 홀이 형성되므로서 연료캡을 닫는 과정에서 제1연료캡이 주유구의 직선방향으로 이동이 가능하게 되어 연료캡가 주유구의 수직방향에서 닫히게 되는 효과가 발생되며, 제1연료캡의 내측면 전면이 밀폐링의 전둘레에 가압력을 가하게 되므로서 밀폐링이 마모 및 손상되는 것이 방지되는 장점이 있는 것이다.As the slot hole is formed in the hinge portion of the first cap member hinged to one side of the oil filling port as described above, the first fuel cap can be moved in a straight direction of the oil filling hole in the process of closing the fuel cap so that the fuel cap is perpendicular to the oil filling hole. The effect of closing in the direction is generated, the front surface of the inner surface of the first fuel cap is applied to the front circumference of the sealing ring has the advantage that the sealing ring is prevented from being worn and damaged.
