자동차 연료탱크의 개폐도어구조Opening and closing door structure of automobile fuel tank

본 발명은 자동차 연료탱크의 개폐도어(FUEL FILLER DOOR)구조에 관한 것으로, 보다 구체적으로는 자동차 연료탱크의 연료를 주입시 개폐도어를 간편하게 개폐할 수 있도록 함은 물론이고 기밀성을 증대시켜 사용의 편의성을 향상시키면서도 개폐에 따른 성능을 향상시키도록 하는 자동차 연료탱크의 개폐도어(FUEL FILLER DOOR)구조에 관한 것이다.The present invention relates to a structure of the fuel tank (FUEL FILLER DOOR) of the vehicle fuel tank, more specifically, to easily open and close the opening and closing door when fuel is injected into the fuel tank of the vehicle as well as to increase the airtightness and ease of use This invention relates to a structure of a fuel filler door of a fuel tank for improving the performance according to opening and closing while improving the performance of the fuel cell.

일반적으로 자동차에는 연료탱크가 필연적으로 구비되어 있는데, 이의 연료탱크의 주입구에는 연료를 주입하는데 따른 개폐도어가 자동차 외부에서 개폐가능토록 구비되어 있는 것이었다.Generally, a fuel tank is inevitably provided in an automobile, and an inlet of the fuel tank is provided with an opening / closing door for injecting fuel so as to be opened and closed outside the vehicle.

이러한 자동차 연료탱크의 개폐도어의 종래구조를 일예를 들어 살펴보면, 이는 연료탱크의 상부 일측면에 원통형의 주입구가 구비되어 있음과 동시에 이의 주입구 끝단에는 나사식으로 개폐되는 개폐도어가 구비되어 있고, 또한, 이와 같은 개폐도어는 자동차의 외부에서 개폐가능토록 구비되어 있는 것이었다.Looking at the conventional structure of the opening and closing door of the fuel tank of the vehicle as an example, it is provided with a cylindrical inlet on the upper side of the fuel tank at the same time it is provided with an opening and closing door that is screwed open and close at the end of the inlet. Such doors were provided to be opened and closed from the outside of the vehicle.

따라서 자동차의 연료탱크에 연료를 주입하기 위하여서는 개폐도어를 나사식으로 역회전시켜 주입구를 개방한 후 연료를 주입하고, 다시 개폐도어를 나사식으로 정회전시켜 폐쇄시키게 되는 것이었다.Therefore, in order to inject fuel into the fuel tank of the vehicle, the opening and closing door was screwed backward to open the injection hole, and then fuel was injected, and the opening and closing door was screwed forward to close.

그러나 이와 같은 종래의 구성에 있어서는 연료탱크의 개폐도어를 나사식으로 개폐함에 따라 도어를 개폐하는데 따른 불편함이 야기되었을 뿐아니라 연료탱크 주입구의 기밀성도 좋지못한 등의 문제점이 있는 것이었다.However, in such a conventional configuration, not only inconvenience caused by opening and closing the door is caused by screwing the opening and closing door of the fuel tank, but also there is a problem such as poor airtightness of the fuel tank inlet.

즉, 개폐도어를 원터치식으로 개폐할 수가 없고, 연료탱크의 주입구를 개폐할때마다 개폐도어의 내경을 주입구의 외경에 정확히 맞추어서 일일히 정,역회전시켜 사용하여야 함으로써 사용상의 불편함이 야기되었던 것이었고, 또한 개폐도어의 내부에 기밀을 위한 패킹부재가 구비되어 있기는 하지만 이는 개폐도어의 체결력에 의해 주입구의 기밀을 유지하는 것이기 때문에 개폐도어의 체결력이 이에 미치지 못하면 누수가 되는 등의 문제점이 야기되었던 것이었다.In other words, the opening and closing door can not be opened and closed by one-touch type, and each time the opening and closing of the fuel tank opening and closing the door should be used in accordance with the exact diameter of the inlet and the forward and reverse rotation to be used daily, causing inconvenience in use. In addition, although the packing member for airtightness is provided inside the opening / closing door, it is to maintain the airtightness of the injection hole by the fastening force of the opening / closing door, so that if the fastening force of the opening / closing door does not reach this, water leakage may occur. It was caused.

본 발명은 상기와 같은 종래의 문제점을 고려하여 이루어진 것으로 그 목적은 자동차 연료탱크의 주입구를 개폐하는 개폐도어를 원터치식으로 간편히 개폐토록 함으로써 사용의 편리성을 좋게하면서도 그 기밀성을 향상시키도록 하는 자동차 연료탱크의 개폐도어(FUEL FILLER DOOR)구조를 제공함에 있다.The present invention has been made in view of the above-described conventional problems, and its object is to open and close the door opening and closing the inlet of the fuel tank of the vehicle by one-touch type to easily open and close the vehicle to improve the convenience of use while improving its airtightness. It is to provide the structure of fuel tank door.

이러한 목적을 달성하기 위한 본 발명은 연료탱크의 개폐도어를 원터치식으로 개폐가능토록 구성함으로써 달성되는데, 즉, 개폐도어의 몸체내에 스프링의 탄성력에 의해 가위식으로 작동되는 작동부재를 구비하여서 이의 작동부재의 작동에 의해 개폐도어가 주입구로 부터 개폐되도록 하는 것이고, 또한, 연료탱크의 주입구 상단부에 스프링의 탄성력에의해 지지되는 패킹부재를 구비하여서 이의 패킹부재의 작동으로 기밀성을 확보토록 하는 것이 특징인 것이다.The present invention for achieving this object is achieved by configuring the opening and closing doors of the fuel tank to be open and close in one-touch manner, that is, the operation of the opening and closing door is provided with an operating member that is operated by scissors spring force by the elastic force of the spring The opening and closing door is opened and closed from the inlet by the operation of the member, and the packing member supported by the elastic force of the spring is provided at the upper end of the inlet of the fuel tank to ensure the airtightness by the operation of the packing member. will be.
