종래 차량의 도어는 힌지를 매개로 차체에 회동가능하게 지지되는 데, 도 1에는 종래 기술에 따른 도어힌지가 도시되어 있다.The door of the conventional vehicle is rotatably supported by the vehicle body via the hinge, Figure 1 shows a door hinge according to the prior art.

종래의 도어힌지는 차체에 마운팅되는 대체로 ㄴ자 형상으로 절곡된 힌지브라켓(1)과, 도어에 마운팅되는 대체로 U자 형상을 하고서 양측 선단부에 플랜지가 절곡되어 형성된 힌지브라켓(2) 및, 상기 제1,2힌지브라켓을 상대 회전가능하게 연결하는 힌지핀(3)으로 구성되어 있다.Conventional door hinges have a hinge bracket (1) bent in a generally N-shape mounted to the vehicle body, a hinge bracket (2) formed by bending a flange at both ends and having a generally? -Shaped mounting on the door, and the first It consists of a hinge pin (3) for rotatably connecting the two hinge brackets.

한편, 도어와 차체사이에는 도어의 단계적인 개폐각도를 제한하는 도어 체커가 구비되어 있다.On the other hand, between the door and the vehicle body is provided with a door checker for limiting the opening and closing angle of the door.

그런데, 현재 차량의 조립 생산라인 중에서 도장라인에서는 도어 체커가 도어에 장착되지 않은 상태에서 도어가 힌지만으로 차체에 조립된 상태에서 여러 번의 도장작업을 행하고 있는 데, 이 경우에 도어를 개방시킨 상태로 도장작업을 해야 하므로, 작업자가 한 손으로 도어를 개방시킨 상태로 다른 손으로 도장작업을 해야 하는 불편함이 있었다.By the way, in the painting production line of the current vehicle assembly line, the painting checker does not have the door checker attached to the door but the door is hinged, but the painting work is carried out several times while the door is opened. Since the painting work should be done, the worker had to open the door with one hand and had to work with the other hand.

또한, 양손으로 도장작업을 해야 하는 경우에는 다른 작업자가 도어를 개방시킨 상태를 유지해야 하므로 2인의 작업자가 필요하게 되어, 작업 공수의 증대와 조립 생산성이 저하된다고 하는 결점이 있었다.In addition, when the painting work is to be performed with both hands, two workers are required because the other worker must keep the door open, and there is a drawback that the number of working hours and the assembly productivity are lowered.

이에 본 발명은 상기와 같은 사정을 감안하여 안출된 것으로, 차량의 조립라인에서 도어 체커가 도어에 장착되지 않은 상태에서 도어를 개방시킨 상태로 작업을 해야 하는 경우에 도어의 개방된 상태를 적절히 유지할 수 있도록 하여 작업의 편의성 증대와 조립 생산성의 향상을 도모할 수 있도록 된 도어힌지구조를 제공함에 그 목적이 있다.Therefore, the present invention has been made in view of the above circumstances, and when the door checker is not mounted on the door in the assembly line of the vehicle, the door must be kept open when the door is properly opened. The purpose of the present invention is to provide a door hinge structure capable of increasing the convenience of work and improving the assembly productivity.

상기와 같은 목적을 달성하기 위한 본 발명은, 차체에 고정되게 장착되는 차 체측 힌지브라켓, 도어에 고정되게 장착되는 도어측 힌지브라켓, 상기 2개의 힌지브라켓을 상대 회전가능하게 연결하는 힌지핀, 상기 힌지핀을 중심으로 상기 도어측 힌지브라켓이 차체측 힌지브라켓에 대해 상대 회전할 때에 도어측 힌지브라켓이 소정 각도 이상으로 회전되면 도어측 힌지브라켓이 차체측 힌지브라켓에 착탈가능하게 걸려지도록 도어측 힌지브라켓과 차체측 힌지브라켓에 각각 형성된 걸림돌기를 구비하고 있다.The present invention for achieving the above object, the vehicle body side hinge bracket fixedly mounted to the vehicle body, the door side hinge bracket fixedly mounted to the door, the hinge pin for rotatably connecting the two hinge brackets, the When the door side hinge bracket is rotated by a predetermined angle or more when the door side hinge bracket is rotated relative to the body side hinge bracket about the hinge pin, the door side hinge bracket is detachably hooked to the body side hinge bracket. It is provided with the locking protrusion formed in the bracket and the vehicle body side hinge bracket, respectively.

바람직하기로는, 상기 차체측 힌지브라켓은 ㄴ자 형상으로 절곡되어 형성되면서 채널을 형성하는 양측 플랜지를 구비하고, 상기 도어측 힌지브라켓은 상기 채널 속에 삽입되어 상기 힌지핀으로 체결되는 ㄷ자 형상의 체결부를 구비하며, 상기 체결부의 일측 외측면과 상기 한쪽 플랜지의 내측면에 각각 상기 걸림돌기가 형성된 것을 특징으로 한다.Preferably, the vehicle body side hinge bracket has a flange formed on both sides to form a channel while being bent in a U-shape, and the door side hinge bracket is provided with a U-shaped fastening portion inserted into the channel and fastened by the hinge pin. The locking projections may be formed on one side outer surface of the fastening portion and the inner surface of the one flange, respectively.

또한, 상기 2개의 걸림돌기는 힌지핀을 중심으로 74도 이상의 위상차를 갖도록 형성된 것을 특징으로 한다.In addition, the two locking projections are characterized in that they are formed to have a phase difference of 74 degrees or more around the hinge pin.

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.

도어를 개폐할 때에 도어 체커의 최대 개방 각도는 70도 정도이고, 도어힌지의 최대 개방각도는 73도 이상으로 설정되어 있다. 따라서, 상기 도어 체커의 최대 개방각도와 도어힌지의 최대 개방각도 사이의 갭을 이용해서 도어힌지에 적절한 형상을 부가해서 도어 체커가 도어에 장착되지 않은 상태에서도 도어가 소정 각도 이상으로 개방될 때에 그 개방각도를 적절히 유지할 수 있게 하는 구조로 되어 있다.When opening and closing the door, the maximum opening angle of the door checker is about 70 degrees, and the maximum opening angle of the door hinge is set to 73 degrees or more. Therefore, by using a gap between the maximum opening angle of the door checker and the maximum opening angle of the door hinge, an appropriate shape is added to the door hinge so that when the door is opened at a predetermined angle or more even when the door checker is not mounted on the door, It has a structure that can maintain the opening angle properly.

도 2에는 본 발명에 따른 도어힌지구조가 자세히 도시되어 있는 바, 즉 차체 에 마운팅되는 대체로 ㄴ자 형상으로 절곡된 힌지브라켓(1)과, 도어에 마운팅되는 대체로 U자 형상을 하고서 양측 선단부에 플랜지가 절곡되어 형성된 힌지브라켓(2) 및, 상기 제1,2힌지브라켓을 상대 회전가능하게 연결하는 힌지핀(3)으로 도어힌지가 구성되어 있다.Figure 2 shows the door hinge structure according to the present invention in detail, that is, the hinge bracket (1) bent in a generally N-shaped shape mounted to the vehicle body, and the flanges on both sides of the generally U-shaped mounted on the door The door hinge is constituted by a hinge bracket 2 that is bent and a hinge pin 3 that rotatably connects the first and second hinge brackets.

그리고, 상기 제1힌지브라켓(1)의 양측 플랜지(1a)가 형성하는 채널 속에 제2힌지브라켓(2)의 ㄷ자 형상 체결부(2a)가 삽입되어 상기 힌지핀(3)으로 서로 상대 회전가능하게 연결되는 데, 상기 체결부(2a)의 외측면과 상기 플랜지(1a)의 대향하는 내측면에는 각각 걸림돌기(1b,2b)가 형성되어 있다.The C-shaped fastening portion 2a of the second hinge bracket 2 is inserted into a channel formed by both flanges 1a of the first hinge bracket 1 so that the hinge pin 3 can be rotated relative to each other. To be connected to each other, the engaging surface (1b, 2b) is formed on the outer surface of the fastening portion (2a) and the inner surface facing the flange (1a), respectively.

상기 2개의 걸림돌기는 대체로 원호 형상으로 일체로 돌출되게 형성되고, 도어가 예컨대 74도 이상으로 개방될 때에는 서로 면착되어 걸려지는 반면에 74도 이하의 각도로 개방될 때에는 서로 간섭을 일으키지 않도록 형성된다. 즉, 도어의 힌지브라켓에 형성되는 걸림돌기와 차체의 힌지브라켓에 형성되는 걸림돌기가 힌지핀을 중심으로 74도 정도의 위상차를 두고 각각의 걸림돌기가 형성되게 된다.The two locking protrusions are formed to protrude integrally in a generally circular arc shape, and are formed to face each other when the doors are opened, for example, above 74 degrees, while not interfering with each other when opening at an angle of 74 degrees or less. That is, the locking protrusions formed on the hinge brackets of the doors and the locking protrusions formed on the hinge brackets of the vehicle body are formed with respective locking protrusions having a phase difference of about 74 degrees with respect to the hinge pins.

따라서, 상기와 같이 걸림돌기가 형성되어 있어도 도어 체커가 도어에 설치되면 도어의 최대 개방 각도가 70도 이하로 제한되므로, 완성차 상태에서 도어를 개폐 할 때에 상기 걸림돌기가 도어의 개폐과정에 방해가 되지 않게 된다.Therefore, even if the locking protrusion is formed as described above, if the door checker is installed in the door, the maximum opening angle of the door is limited to 70 degrees or less, so that the locking protrusion does not interfere with the opening and closing process of the door when the door is opened and closed in a finished vehicle. do.

도 3에는 도어가 74도 이상의 각도로 개방될 때의 도어힌지의 작동 상태가 도시되어 있는 바, 도어가 74도 이상의 각도로 개방될 때에 도어측 힌지브라켓이 힌지핀을 중심으로 회전하게 되면, 도어측 힌지브라켓의 걸림돌기가 차체측 힌지브라켓의 걸림돌기와 면착되어 도어의 개방상태를 유지할 수 있게 된다.Figure 3 shows the operating state of the door hinge when the door is opened at an angle of more than 74 degrees, when the door-side hinge bracket is rotated about the hinge pin when the door is opened at an angle of more than 74 degrees, The locking projections of the side hinge brackets face the locking protrusions of the body side hinge brackets to maintain the open state of the door.

그리고, 상기 양측 걸림돌기의 면착으로 인해 도어측 힌지브라켓이 한쪽으로 기울어지게 되어 도어측 힌지브라켓이 차체측 힌지브라켓에 닿을 수 있게 되는 데, 이를 방지하기 위해서는 도어측 힌지브라켓과 차체측 힌지브라켓 사이의 갭만큼과 상기 걸림돌기가 면착되게 하면, 걸림돌기의 지나친 마모를 줄여줄 수 있게 된다.In addition, the door-side hinge bracket is inclined to one side due to the attachment of the locking protrusions on both sides, so that the door-side hinge bracket can reach the body-side hinge bracket, in order to prevent the door-side hinge bracket and the body-side hinge bracket. As the gap between and the engaging projections, the excessive wear of the engaging projections can be reduced.

상기와 같이 도어가 개방된 상태로 유지됨에 따라 예컨대 도장라인에서 작업자가 도어의 개방상태를 유지하기 위해 도어를 한 손으로 잡고 있을 필요가 없게 되어, 도장 작업을 양손으로 편리하게 할 수 있을 뿐만 아니라 보조 작업자가 필요 없게 되어, 작업 생산성의 향상과 작업 공수의 저하를 도모할 수 있게 된다.As the door is kept open as described above, the operator does not need to hold the door with one hand to maintain the door open, for example, in the painting line, so that the painting work can be conveniently performed with both hands. An assistant worker is not required, so that work productivity can be improved and work man-hours can be reduced.

한편, 도장 작업이 완료된 후에는 작업자가 도어를 다시 닫아주면, 도어측 힌지브라켓의 걸림돌기가 차체측 힌지브라켓의 걸림돌기로부터 이탈되게 된다.On the other hand, after the painting work is completed, if the worker closes the door again, the locking projection of the door-side hinge bracket is separated from the locking projection of the body-side hinge bracket.

이상 설명한 바와 같이 본 발명에 따른 도어힌지구조에 의하면, 도어 체커가 도어에 장착되지 않은 상태에서 도어의 개방 상태를 2개의 걸림돌기를 매개로 적절히 유지시켜 줄 수 있으므로, 차량의 조립 생산라인에서 도어를 개방시킨 상태로 작업을 할 때에 도어의 개방 상태를 유지하기 위해 작업자가 도어를 한 손으로 잡아줄 필요가 없으므로, 작업이 편리해질 뿐만 아니라 생산성도 향상되게 되는 등의 효과가 있게 된다.As described above, according to the door hinge structure according to the present invention, it is possible to properly maintain the open state of the door through the two locking projections without the door checker mounted on the door. When working in the open state, the operator does not need to hold the door with one hand to maintain the open state of the door, so that the work is not only convenient but also the productivity is improved.
