상기 연료도어는 통상적으로 스틸이나 플라스틱 소재로 제작되고, 운전자가 간단한 버튼 등의 조작으로 용이하게 개방시킬 수 있을 뿐만 아니라 연료의 충진후 에는 단지 연료도어를 강제적으로 밀어서 닫아주기만 하면 자동적으로 닫힌 상태를 유지할 수 있는 잠금구조도 갖추어져 있다.The fuel door is usually made of steel or plastic material, and can be easily opened by the operator with a simple button operation, and the fuel door is automatically closed by simply pushing the fuel door to close the fuel door after filling. It also has a lock structure that can be maintained.

상기와 같은 종래의 연료도어 및 그 잠금구조는 구조가 복잡하여 제작원가 및 중량의 상승에 일조하고 있으므로, 이를 간단한 구조로 제작할 필요가 있었다.Since the conventional fuel door and its locking structure are complicated in structure and contribute to the increase in manufacturing cost and weight, it has been necessary to manufacture it in a simple structure.

이에 본 발명은 상기와 같은 사정을 감안하여 안출된 것으로, 구조가 간단하여 중량 및 원가절감을 도모할 수 있으면서 연료도어가 원활하게 개폐될 수 있도록 하여 작동신뢰성도 향상시킬 수 있도록 된 차량의 연료도어구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above circumstances, and the fuel door of the vehicle is designed so that the fuel door can be smoothly opened and closed while improving the weight and cost due to its simple structure. The purpose is to provide a structure.

상기와 같은 목적을 달성하기 위한 본 발명은, 힌지를 중심으로 회동가능하게 장착된 캐쳐와, 힌지를 매개로 회동가능하게 장착된 연료도어, 이 연료도어를 개방시키는 방향으로 밀어주는 판스프링, 상기 캐쳐가 외력에 의해 회동되지 않은 상태에서는 상기 판스프링에 의해 연료도어가 회동되지 않도록 억제하는 회동방지수단을 구비하고 있다.The present invention for achieving the above object, the catcher rotatably mounted around the hinge, the fuel door rotatably mounted via the hinge, the leaf spring to push in the direction of opening the fuel door, the The catcher is provided with anti-rotation means for suppressing the fuel door from being rotated by the leaf spring in a state where the catcher is not rotated by an external force.

바람직하기로는, 상기 회동방지수단은 상기 연료도어의 아암과 상기 캐쳐의 대향면에 각각 형성된 돌기로서, 상기 아암의 돌기는 상면에 곡면이 형성되고 상기 캐쳐의 돌기는 하면에 곡면이 형성되어 상기 연료도어의 개방상태에서는 상기 두 곡면이 접촉되고 닫힘상태에서는 아암의 돌기가 캐쳐의 돌기를 타고 넘어 상기 두 돌기가 서로 걸려지는 것을 특징으로 하고, 상기 캐쳐는 외력으로 강제 회동시킬 수 있도록 조작버튼과 연결되고, 상기 외력이 소멸되면 원래의 위치로 복귀시키도록 복귀스프링이 설치된 것을 특징으로 한다.Preferably, the anti-rotation means is a projection formed on the opposite surface of the arm and the catcher of the fuel door, the projection of the arm is a curved surface formed on the upper surface and the projection of the catcher is formed a curved surface on the lower surface of the fuel In the open state of the door, the two curved surfaces are in contact with each other. In the closed state, the protrusion of the arm crosses the catch of the catcher, and the two protrusions are caught with each other. When the external force is extinguished, the return spring is installed to return to the original position.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1에는 본 발명에 따른 연료도어가 닫힌 상태의 단면이 개략적으로 도시되어 있는 바, 차체에 일측이 개방된 대략 "ㄷ"자형상의 브라켓(1)이 고정되게 장착되고, 이 브라켓(1)의 한쪽 벽면에는 차체의 내부를 향해 관통구멍이 형성되며, 상기 브라켓(1)이 형성하는 내부공간에는 대략 L자 형상을 한 캐쳐(2)가 그 힌지(2a)를 매개로 회동가능하게 설치되어 있다.1 is a cross-sectional view schematically showing the fuel door according to the present invention in a closed state, the bracket having a substantially "c" shaped opening (1) open on one side of the vehicle body is fixedly mounted, A through hole is formed in one wall toward the inside of the vehicle body, and the catcher 2 having a substantially L-shape is rotatably provided through the hinge 2a in the inner space formed by the bracket 1. .

상기 캐쳐(2)의 일단은 상기 관통구멍을 통해 브라켓(1)의 외측으로 연장되면서 와이어 등을 통해 운전자가 조작할 수 있는 조작버튼(도시되지 않음)과 연결되어, 운전자가 조작버튼을 조작하게 되면 상기 캐쳐(2)가 그 힌지(2a)를 중심으로 시계방향으로 회전하게 된다.One end of the catcher 2 is connected to an operation button (not shown) that the driver can operate through a wire or the like while extending outward of the bracket 1 through the through hole, thereby allowing the driver to operate the operation button. When the catcher (2) is rotated clockwise around the hinge (2a).

상기와 같이 회전된 상태에서 운전자가 그 조작버튼의 조작을 해방시키게 되면, 상기 캐쳐(2)가 원래의 위치로 복귀될 수 있도록 상기 캐쳐(2)에는 복귀스프링(3)이 설치되어 있다. 이 복귀스프링(3)은 캐쳐(2)가 시계방향으로 회전할 때에 압축되면서 탄성복원력을 저장하고 있다가 캐쳐(2)에 가해진 외력이 소멸될 때에 그 탄성 복원력으로 캐쳐(2)를 원래의 위치로 복귀시켜주게 된다.When the driver releases the operation button in the rotated state as described above, the catcher 2 is provided with a return spring 3 so that the catcher 2 can be returned to its original position. The return spring 3 stores the elastic restoring force by being compressed when the catcher 2 rotates in the clockwise direction, and then returns the catcher 2 with its elastic restoring force when the external force applied to the catcher 2 is extinguished. Will return to.

상기 캐쳐(2)의 힌지(2a)와 인접한 부위에는 연료도어(4)가 그 힌지(4a)를 매개로 회동가능하게 설치되어 있는 데, 상기 연료도어(4)는 차체의 내측을 향해 대략 J자 형상을 한 아암(4b)이 돌출되게 형성되고, 이 아암(4b)의 선단부위에 상기 힌지(4a)가 설치되어 있다.A fuel door 4 is rotatably installed at a portion adjacent to the hinge 2a of the catcher 2 via the hinge 4a, and the fuel door 4 is approximately J toward the inside of the vehicle body. The arm-shaped arm 4b protrudes, and the said hinge 4a is provided in the front-end | tip part of this arm 4b.

상기 연료도어(4)의 아암과(4b)과 상기 캐쳐(2)의 서로 대향하는 면에는 각각 돌기(4c,2b)가 형성되어 있는 데, 연료도어(4)가 닫힌 상태에서는 아암(4b)의 돌기(4c)가 캐쳐(2)의 돌기(2b)보다 위쪽에 배치된 상태에서 서로 접촉하여 걸려지도록 각 돌기가 형성된다.The projections 4c and 2b are formed on the arms of the fuel door 4 and the surfaces of the catcher 2 that face each other, and the arms 4b in the closed state of the fuel door 4. Each projection is formed such that the projections 4c of the catchers 2 are caught in contact with each other in a state of being disposed above the projections 2b of the catcher 2.

상기 아암(4b)의 돌기(4c)의 상면과 상기 캐쳐(2)의 돌기(2b)의 하면은 곡면으로 형성되는 한편, 상기 아암(4b)과 캐쳐(2)사이에는 판스프링(5)이 장착되어 상기 연료도어(4)의 아암(4b)을 반시계방향으로 항상 밀어주게 되어 있다.The upper surface of the projection 4c of the arm 4b and the lower surface of the projection 2b of the catcher 2 are formed in a curved surface, while a leaf spring 5 is formed between the arm 4b and the catcher 2. It is mounted so that the arm 4b of the fuel door 4 is always pushed counterclockwise.

도 2에는 본 발명에 따른 연료도어가 개방된 상태의 단면을 개략적으로 도시한 것인 바, 운전자가 조작버튼을 조작하게 되면 상기 캐쳐(2)가 시계방향으로 그 힌지(2a)를 중심으로 회동하게 되고, 이로 인해 캐쳐(2)의 돌기(2b)에 의해 회동이 억제되어 있던 연료도어(4)의 아암(4b)이 그 힌지(4a)를 중심으로 판스프링(5)의 탄성 복원력에 의해 강제적으로 반시계방향으로 회동하면서 팝업됨에 따라 연료도어가 자동적으로 개방되게 된다.Figure 2 schematically shows a cross-section of the fuel door according to the present invention in the open state, when the driver operates the operation button, the catcher 2 is rotated around the hinge (2a) in the clockwise direction As a result, the arm 4b of the fuel door 4 whose rotation is suppressed by the projection 2b of the catcher 2 is caused by the elastic restoring force of the leaf spring 5 around the hinge 4a. The fuel door opens automatically as it pops up while forcibly turning counterclockwise.

상기와 같이 연료도어가 개방된 상태에서 연료캡(도시되지 않음)을 탈거하여 연료주입을 완료한 후에 팝업된 연료도어(4)를 강제적으로 닫아주게 되면, 아암(4b)에 형성된 돌기(4c)의 곡면이 캐쳐(2)에 형성된 돌기(2b)의 곡면과 맞닿은 상태서 미끄럼 이동하다가 캐쳐(2)의 돌기(2b)를 완전히 타고 넘어서 안착되어 도 1에 도시된 상태로 되돌아 오게된다.When the fuel door (not shown) is removed in the state where the fuel door is opened as described above, and the fuel door 4 forcibly closed after the fuel injection is completed, the protrusion 4c formed on the arm 4b While the curved surface of the catcher 2 is in contact with the curved surface of the projection 2b formed on the catcher (2) is completely slipped over the projection (2b) of the catcher 2 is returned to the state shown in FIG.

이 상태에서 판스프링(5)은 압축도어 캐쳐(2)와 아암(4b)을 각각 밀어주게 되므로, 연료도어의 안정된 닫힌 상태를 유지할 수 있게 된다.In this state, since the leaf spring 5 pushes the compression door catcher 2 and the arm 4b, respectively, it is possible to maintain a stable closed state of the fuel door.

이상 설명한 바와 같이 본 발명에 따른 연료도어구조에 의하면, 그 구성이 간단하여 용이하게 제작할 수 있으므로, 중량 및 원가절감을 도모할 수 있고, 스프링의 탄성력으로 연료도어의 닫힌 상태를 안정되게 유지할 수 있으며, 간단한 구조로서 개방 및 폐쇄동작의 신뢰성을 향상시킬 수 있는 등의 효과가 있다.As described above, according to the fuel door structure according to the present invention, since its configuration is simple and can be easily manufactured, weight and cost can be reduced, and the closed state of the fuel door can be stably maintained by the elastic force of the spring. As a simple structure, the reliability of the opening and closing operations can be improved.
