Abstract

PURPOSE: Double sealing structure of a fuel filler for a vehicle is provided to improve sealing efficiency of the fuel filler by mounting sealing members doubly in an inner fuel cap. CONSTITUTION: An inner fuel cap(22) is inserted to a fuel filler to close, and supported elastically by a spring(16) installed in a fuel filler door housing(20). A notch(54) is formed around the middle of the inner fuel cap, and a notch(56) is formed around the lower part of the inner fuel cap. A recess(58) is formed in the inner wall of the fuel filler door housing(20). A second sealing member(52) is installed in the notch formed around the middle of the body, and a first sealing member(50) is mounted in the notch formed around the lower part of the body. Both ends of the first sealing member are inserted to the notch and the recess to prevent deformation in opening and closing the fuel filler door. The first sealing member is placed between the notch in the lower part of the inner fuel cap and the recess of the door housing, and the second sealing member is installed in the notch formed in the middle of the inner fuel cap. Sealing efficiency is improved with closing the fuel cap doubly.

Description

이중 실링 기능을 가진 연료 주입구 도어 구조{Fuel door with double sealing structure}Fuel door with double sealing structure

본 발명은 자동차 연료 주입구의 이중 실링구조에 관한 것으로서, 상세하게는 연료 주입구 도어에 실링재를 이중으로 설치하여 실링기능을 개선하고자 하는 이중 실링 기능을 가진 연료 주입구 도어 구조에 관한 것이다.The present invention relates to a double sealing structure of a vehicle fuel inlet, and more particularly to a fuel inlet door structure having a double sealing function to improve the sealing function by installing a sealing material in the fuel inlet door in a double.

종래 자동차 연료 주입구 개폐 기능은 수나사 형태를 가진 연료 주입구 캡과 암나사 형태의 연료 주입구와의 나사 체결로 이루어졌다.The conventional vehicle fuel inlet opening and closing function is made by screwing the fuel inlet cap having a male thread form and the female inlet form fuel inlet.

때문에 연료 주입구 캡의 분실, 조작 실수에 의한 밀폐 불량, 캡의 개폐 조작시 연료로 인한 손이나 옷이 더럽혀지는 부담, 개폐시 일정한 TOQUE를 부여해야 하는 등 여러 불편을 해소하기 위하여 개선기술로 연료 주입구 도어 자체에 연료 주입구와의 실링(SEALING) 역할을 하는 구조가 고안됐었다.Therefore, the fuel injection hole is improved to solve various inconveniences such as loss of the fuel inlet cap, poor sealing due to a mistake in operation, a burden of dirty hands or clothes due to fuel during opening and closing of the cap, and a constant torque to be opened and closed. The door itself has been designed to seal with the fuel inlet.

도 1과 도 2는 이와 같은 종래의 개선된 연료 주입구 도어의 구조이다.1 and 2 show the structure of such a conventional improved fuel inlet door.

기존에 별도였던 연료 주입구 캡(22)을 연료 주입구 도어(26)와 연료주입구 도어 하우징(20)내에 스프링(16)과 연결시키고 상기 연료 주입구 캡(22)의 하단 주위는 실링기능을 하는 오링(12)을 끼워 넣어 연료 주입구(18)의 상단과 접촉하게 하는 구조로 연료 주입구 도어(26)가 도어 힌지(28)를 기준으로 닫힘과 동시에 스프링(16)의 가압으로 내부 연료 캡(22)을 이동시키고 오링(12)을 이용해 연료 주입구를 밀폐시킨다.The fuel inlet cap 22, which was previously separate, is connected to the spring 16 in the fuel inlet door 26 and the fuel inlet door housing 20, and the O-ring has a sealing function around the lower end of the fuel inlet cap 22. 12) is inserted into contact with the upper end of the fuel inlet 18, the fuel inlet door 26 is closed with respect to the door hinge 28 and at the same time pressurizing the spring 16 to open the internal fuel cap 22 Move and seal the fuel inlet with O-ring 12.

이와 같은 개선된 종래 기술에서의 문제점은 실링(sealing)의 성능이다.A problem with this improved prior art is the performance of the sealing.

연료 주입구(18)의 밀폐성은 내부 연료 캡(22)에 끼워져 있는 오링(12)에 좌우된다. 그러나 상기 오링(12)의 장착에 있어서 단순히 내부 연료 캡(22)에 끼워져 있기 때문에 외부 온도 변화에 의한 팽창, 연료가 오링(12)에 묻음으로써 미끄러워짐 등으로 인해 탈거 위험이 있고, 연료 주입구 도어(26)의 개폐횟수의 증가로 오링(12)의 변형 및 파손이 발생하므로 충분한 실링 성능을 발휘하지 못해 누유의 단점이 있었다.The tightness of the fuel inlet 18 depends on the O-ring 12 fitted to the internal fuel cap 22. However, since the O-ring 12 is simply fitted to the internal fuel cap 22, there is a risk of detachment due to expansion due to an external temperature change, slipping due to fuel being buried in the O-ring 12, and the fuel inlet door. Since the deformation and breakage of the O-ring 12 occurs due to the increase and decrease of the opening and closing (26), there is a disadvantage of leakage due to insufficient sealing performance.

본 발명은 전술한 문제점을 해결학 위하여 발명한 것으로서, 내부 연료 캡에 이중의 실링 구조를 제공하여 완벽한 연료 주입구의 밀폐를 이루고자 하는 목적을 가지고 있다.The present invention has been invented to solve the above problems, and has an object of providing a perfect sealing of the fuel inlet by providing a double sealing structure in the internal fuel cap.

본 발명은 전술한 목적을 달성하기 위하여 연료 주입구 도어에 설치된 연료 주입구 도어 하우징 내부에 스프링으로 탄력 지지되는 내부 연료 캡이 연료 주입구에 삽입되어 밀폐 시키는 연료 주입구 도어 구조에 있어서, 상기 내부 연료 캡의 몸체 중앙의 둘레에 노치를 형성하고, 상기 내부 연료 캡의 몸체 하부 둘레에 노치를 형성하며, 상기 연료 주입구 도어 하우징의 내부 벽면에 상기 노치와 같은 높이로 오목 폼을 형성하여 1차 실링재를 설치하고, 상기 노치에 2차 실링재를 설치하여 이중으로 밀폐를 시키는 것을 특징으로 하는 이중 실링 기능을 가진 연료 주입구 도어 구조를 제공한다.According to an aspect of the present invention, there is provided a fuel inlet door structure in which an internal fuel cap elastically supported by a spring is inserted into a fuel inlet to seal the fuel inlet door housing installed in the fuel inlet door housing. Forming a notch around the center of the body, forming a notch around the lower body of the inner fuel cap, and forming a concave foam at the same height as the notch on the inner wall of the fuel inlet door housing to install the primary sealing material, Provides a fuel inlet door structure having a double sealing function characterized in that the sealing is installed in a double by the secondary sealing material in the notch.

이하 첨부된 도면을 참조하여 본 발명의 구성을 상세히 설명하면 다음과 같다.Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

도 3은 본 발명의 연료 주입구 도어를 도시한 종단면도로서, 연료 주입구 도어 하우징(20)의 내부에 설치되는 스프링(16)에 의하여 탄력 지지되는 내부 연료 캡(22)의 몸체 중앙의 둘레에 노치(54)를 형성하고, 상기 내부 연료 캡(22)의 몸체하부 둘레에 노치(56)를 형성한다.3 is a longitudinal sectional view of the fuel inlet door of the present invention, notched around the center of the body of the internal fuel cap 22 elastically supported by a spring 16 installed inside the fuel inlet door housing 20. And a notch 56 is formed around the lower body of the internal fuel cap 22.

그리고 연료 주입구 도어 하우징(20)의 내부 벽면에 상기 노치(54)와 같은 높이로 오목 폼(58)을 형성한다.A concave foam 58 is formed on the inner wall of the fuel inlet door housing 20 at the same height as the notch 54.

몸체 중앙의 둘레에 형성된 노치(54)에 2차 실링재(52)를 설치하고, 몸체 하부 둘레에 형성된 노치(56)에 1차 실링재(50)를 설치한다. 상기 1차 실링재(50)의 양단이 노치(54)와 오목 폼(58)에 끼워져 고정되어 연료 주입구 도어를 여닫더라도 빠지거나 변형이 일어나지 않는다.The secondary sealing material 52 is installed in the notch 54 formed around the center of the body, and the primary sealing material 50 is installed in the notch 56 formed around the lower part of the body. Both ends of the primary sealing material 50 are fitted into the notch 54 and the concave form 58 to be fixed so that the fuel inlet door may not be pulled out or deformed.

종래에는 오링이 단순하게 내부 연료 캡(22)에 끼워져 연료 주입구(18)의 단부에 눌려져 밀폐되었지만, 본 발명은 1차 실링재(5)가 노치(56)와 오목 폼(58)에 끼워져 연료 주입구(18)에 눌려 지므로 빠지거나 변형의 염려가 줄어든다.Conventionally, the O-ring is simply fitted into the inner fuel cap 22 and pressed to the end of the fuel inlet 18 to be sealed. However, in the present invention, the primary sealing material 5 is inserted into the notch 56 and the concave foam 58 so that the fuel inlet is closed. Pressed by (18), so there is less fear of falling out or deformation.

1차로 밀폐가 된 후에 상기 내부 연료 캡(22)의 중앙에 형성된 노치(54)에 2차 실링재(52)를 끼워 2차로 밀폐 시킨다.After the first seal, the secondary sealing material 52 is inserted into the notch 54 formed at the center of the internal fuel cap 22 to seal the secondary.

상기 1차 실링재와 2차 실링재는 통상의 제품을 사용한다.The primary sealing material and the secondary sealing material use a conventional product.

이상과 같이 본 발명은 오링 하나만 단순하게 끼워 밀폐시키던 연료 주입구 도어구조를 내부 연료 캡의 하부에 노치를 주고 연료 주입구 도어 하우징의 내벽면에 오폭 품을 형성하여 그 사이에 1차 실링재를 위치시켜 고정하고, 내부 연료캡의 중간에 노치를 주어 2차 실링재를 설치하여 이중으로 밀폐시켜 실링 성능을 개선하는 효과가 있다.As described above, the present invention provides a notch to the lower portion of the internal fuel cap by inserting the fuel inlet door structure, which is simply fitted with only one o-ring, to form a misalignment on the inner wall surface of the fuel inlet door housing, thereby positioning and fixing the primary sealing material therebetween. And, giving a notch in the middle of the internal fuel cap has a secondary sealing material installed to double the sealing effect is to improve the sealing performance.
