본 발명은 상용 차량의 플랩도어 힌지에 관한 것으로, 특히 구조가 간단하면서도 내구성이 좋을 뿐만 아니라 플랩도어를 원활하게 개폐시킬 수 있도록 지지하는 상용 차량의 플랩도어 힌지구조에 관한 것이다.The present invention relates to a flap door hinge of a commercial vehicle, and more particularly, to a flap door hinge structure of a commercial vehicle that supports not only the structure is simple and durable, but also smoothly opens and closes the flap door.

종래 상용 차량에는 주유구 등을 개폐하는 데에 플랩도어가 사용되는 데, 이 플랩도어는 도 1에 도시된 바와 같이, 차체(1)에 지지브라켓(2)의 일단이 고정되게 부착되고, 상기 지지브라켓(2)의 타단은 힌지핀(3)의 외주면을 감싸서 지지하게 되어 있으며, 상기 힌지핀(3)에는 플랩도어(4)의 일단이 끼워져 지지되어, 플랩도어(4)가 상기 힌지(4)와 지지브라켓(2)을 매개로 차체에 회동가능하게 지지되어 있었다.In a conventional commercial vehicle, a flap door is used to open and close a gas inlet, and the flap door is fixedly attached to one end of the support bracket 2 to the vehicle body 1, as shown in FIG. The other end of the bracket 2 surrounds and supports the outer circumferential surface of the hinge pin 3, and one end of the flap door 4 is supported by the hinge pin 3 so that the flap door 4 is supported by the hinge 4. ) And the support bracket (2) were rotatably supported by the body.

그리고, 상기 플랩도어(4)의 개폐과정에 플랩도어(4)에 탄력을 부여하면서 플랩도어(4)의 개방 및 닫힌 상태를 유지해주는 원호 형상의 판스프링(5)이 구비되어 있는 데, 이 판스프링(5)의 일단은 상기 플랩도어(4)에 힌지핀(6)으로 장착되는 반면에 타단은 차체에 힌지핀을 매개로 설치되어 있다.In addition, an arc-shaped leaf spring 5 is provided to maintain the open and closed state of the flap door 4 while providing elasticity to the flap door 4 in the opening and closing process of the flap door 4. One end of the leaf spring (5) is mounted to the flap door (4) by a hinge pin (6) while the other end is installed on the vehicle body via a hinge pin.

그런데, 상기와 같은 종래의 힌지구조에서는 상기 판스프링(5)이 2개의 힌지핀과 브라켓을 매개로 설치됨에 따라 부품수 및 작업공수의 증가로 원가상승을 초래하는 한 원인으로 작용하고 있을 뿐만 아니라 플랩도어(4)의 개폐과정에 판스프링이 구부러지거나 펴지거나 하는 동작이 원만하지 못하여 플랩도어의 개폐동작이 부드럽지 못하게 이루어지고, 또한 장시간 사용할 경우에는 상기 힌지 부위에 녹이 슬거나 힌지핀이 이탈하는 등으로 인해 플랩도어가 개폐된 상태를 제대로 유지하지 못한다고 하는 결점이 있었다.However, in the conventional hinge structure as described above, as the leaf spring 5 is installed through the two hinge pins and the bracket, the plate spring 5 acts as a cause of the cost increase due to the increase in the number of parts and the labor. In the opening and closing process of the flap door (4), the plate spring is bent or unfolded so that the opening and closing action of the flap door is not smooth, and in case of prolonged use, the rust or hinge pin is released from the hinge part. There is a drawback that the flap door is not kept properly opened due to such.

이에 본 발명은 상기와 같은 사정을 감안하여 안출된 것으로, 구조가 간단하여 부품수와 작업공수 및 원가절감을 도모할 수 있을 뿐만 아니라 내구성도 향상시킬 수 있고, 플랩도어의 개폐동작도 부드럽고 원활하게 이루어질 수 있도록 된 상용 차량의 플랩도어 힌지구조를 제공함에 그 목적이 있다.Therefore, the present invention has been devised in view of the above circumstances, and the structure is simple, which can not only reduce the number of parts, labor, and cost, but also improve durability, and smoothly and smoothly open and close the flap door. It is an object of the present invention to provide a flap door hinge structure of a commercial vehicle that can be achieved.

상기와 같은 목적을 달성하기 위한 본 발명은, 플랩도어를 차체에 회동가능하게 지지하는 힌지핀과, 상기 플랩도어에 회전가능하게 장착된 롤러 및, 이 롤러를 안내이동시키면서 상기 플랩도어의 개폐과정에 판스프링 역할을 하는 롤러가이드를 구비하고 있다.The present invention for achieving the above object, the hinge pin for rotatably supporting the flap door to the vehicle body, a roller rotatably mounted to the flap door, and the opening and closing process of the flap door while guiding the roller It has a roller guide that serves as a leaf spring.

바람직하기로는, 상기 플랩도어에는 장착브라켓의 일단이 고정되게 부착되면서 상기 장착브라켓의 타단은 소정 간격을 두고 이격되게 형성되어 상기 힌지핀에 끼워지는 원호 형상으로 절곡된 2개의 브릿지를 구성하고, 상기 브릿지 사이의 공간에 상기 롤러가 배치되어 상기 브릿지에 롤러축이 회전가능하게 설치되며, 상기 롤러가이드의 일단은 상기 힌지핀에 끼워져 설치됨과 더불어 타단은 상기 롤러가 끼워져 안내이동될 수 있도록 U자 형상으로 절곡되게 형성된 것을 특징으로 한다.Preferably, the one end of the mounting bracket is fixedly attached to the flap door while the other end of the mounting bracket is spaced apart at a predetermined interval to constitute two bridges bent in an arc shape to be fitted to the hinge pin, The roller is disposed in the space between the bridges so that the roller shaft is rotatably installed on the bridge, one end of the roller guide is fitted to the hinge pin and the other end is U-shaped so that the roller can be inserted and guided. Characterized in that formed to be bent.

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

도 2에는 본 발명에 따른 힌지가 장착된 플랩도어가 닫혀진 상태의 사시도가 도시되어 있는 바, 즉 플랩도어(10)의 배면에는 대략 사각형상을 이루는 장착브라켓(11)의 일단이 고정되게 부착되는 반면에 상기 장착브라켓(11)의 타단은 서로 이격되게 형성된 2개의 브릿지(11a,11b)를 갖추고 있다. 상기 브릿지(11a,11b)는 원호 형상으로 구부러져서 힌지핀(12)의 외주면을 감싸는 형태로 설치되어 있다.Figure 2 shows a perspective view of the hinged flap door is closed in accordance with the present invention, that is, one end of the mounting bracket (11) which is formed in a substantially rectangular shape on the back of the flap door 10 is fixedly attached On the other hand, the other end of the mounting bracket 11 is provided with two bridges (11a, 11b) formed to be spaced apart from each other. The bridges 11a and 11b are bent in an arc shape and are provided in a form of surrounding the outer circumferential surface of the hinge pin 12.

또한, 상기 힌지핀(12)에는 차체에 그 일단이 고정되게 부착되는 차체브라켓(13)의 타단이 감싸진 형태로 설치되어, 상기 플랩도어(10)가 그 장착브라켓(11)과 힌지핀(12) 및 차체브라켓(13)을 매개로 차체에 회동가능하게 지지된다.In addition, the hinge pin 12 is installed in a form in which the other end of the vehicle body bracket 13 is fixedly attached to one end of the vehicle body so that the flap door 10 has its mounting bracket 11 and the hinge pin ( 12) and the body bracket 13 is rotatably supported by the vehicle body.

그리고, 상기 힌지핀(12)의 길이방향을 따른 대략 중앙 부위에는 대체로 U자 형상을 이루고서 판스프링 역할을 하는 롤러가이드(14)의 일단이 감겨진 형태로 설치되고, 상기 롤러가이드(14)의 타단은 도 3에 자세히 도시된 바와 같이 상기 일단보다 더 연장되어서 소정 각도로 절곡되어 있다.In addition, one end of the roller guide 14 serving as a leaf spring is generally formed in a substantially U-shape along the longitudinal direction of the hinge pin 12, and the roller guide 14 is wound. The other end of is bent at a predetermined angle extending further than the one end as shown in detail in FIG.

상기 2개의 브릿지(11a,11b)에 그 롤러축(15a)이 걸치는 형태로 배치된 롤러(15)는 상기 2개의 브릿지(11a,11b)에 대해 상기 롤러축(15a)이 회전가능하게 설치됨과 더불어 상기 롤러(15)는 상기 롤러가이드(14)에 끼워져서 롤러가이드(14)를 따라서 안내이동되게 설치된다.The roller 15 arranged in such a manner that the roller shaft 15a is applied to the two bridges 11a and 11b has the roller shaft 15a rotatably installed with respect to the two bridges 11a and 11b. In addition, the roller 15 is fitted to the roller guide 14 and is installed to be guided along the roller guide 14.

상기 롤러(15)가 2개의 브릿지(11a,11b)사이에 배치된 상태에서 롤러가이드(14)를 따라 안내이동될 수 있도록 2개의 브릿지(11a,11b) 사이에는 적절한 공간이 형성되게 2개의 브릿지(11a,11b)가 서로 이격되게 형성된다.Two bridges so that an appropriate space is formed between the two bridges 11a and 11b so that the roller 15 can be guided along the roller guide 14 while the roller 15 is disposed between the two bridges 11a and 11b. 11a and 11b are formed spaced apart from each other.

도 2에 도시된 바와 같이 상기 플랩도어(10)가 완전히 닫힌 상태에서 작업자가 상기 플랩도어(10)를 개방시키는 방향으로 회동시켜 주면, 상기 플랩도어(10)는 그 힌지핀(12)을 매개로 회동되게 되고, 상기 플랩도어(10)의 장착브라켓(11)에 설치된 롤러(15)는 롤러가이드(14)를 따라서 안내이동되어, 플랩도어(10)의 개폐동작이 롤러(15)와 롤러가이드(14)를 매개로 원활하고 부드럽게 이루어지게 된다.As shown in FIG. 2, when the operator rotates the flap door 10 in a direction in which the flap door 10 is completely closed, the flap door 10 carries the hinge pin 12. The roller 15 installed in the mounting bracket 11 of the flap door 10 is guided and moved along the roller guide 14, so that the opening and closing operation of the flap door 10 is performed by the roller 15 and the roller. The guide 14 is made smooth and smooth.

그리고, 플랩도어(10)가 완전히 개방되게 되면, 도 3에 도시된 바와 같이 롤러(15)는 롤러가이드(14)의 절곡된 선단부(15a)에 위치하게 되는 바, 이와 같이 롤러(15)가 롤러가이드(14)를 따라서 이동하는 과정에 롤러가이드(14)는 벌어졌다가 다시 원래의 형상으로 복귀되면서 종래 판스프링의 역할을 대신하게 된다.When the flap door 10 is fully opened, as shown in FIG. 3, the roller 15 is positioned at the bent end portion 15a of the roller guide 14. In the process of moving along the roller guide 14, the roller guide 14 is opened and then returned to its original shape, replacing the role of the conventional leaf spring.

이상 설명한 바와 같이 본 발명에 따른 상용 차량의 플랩도어 힌지구조에 의하면, 구조가 간단하여 부품수와 작업 공수 및 원가절감을 도모할 수 있고, 판스프링 역할을 하는 롤러가이드를 따라 안내이동되는 구름 롤러를 매개로 플랩도어의 개폐동작이 부드럽고 원활하게 이루어질 수 있을 뿐만 아니라 내구성도 향상되어 플랩도아가 처지게 될 염려도 없는 등의 효과가 있게 된다.As described above, according to the flap door hinge structure of the commercial vehicle according to the present invention, the structure is simple, it is possible to reduce the number of parts, labor and cost, and rolling roller guided along the roller guide serving as a leaf spring The opening and closing operation of the flap door can be made smoothly and smoothly, and the durability is also improved, so there is no fear that the flap door will sag.
