The door side plate 120 coupled with the vehicle body side plate 110 is fixedly installed.

상기 차체측 플레이트(110)와 도어측 플레이트(120)는 고정핀(130)으로 연결되어 있으며, 고정핀(130)은 도어측 플레이트(120)에 고정되어 있다.The vehicle body side plate 110 and the door side plate 120 are connected by a fixing pin 130, and the fixing pin 130 is fixed to the door side plate 120.

즉, 고정핀(130)의 중간에 돌출된 록킹돌기(131)가 도어측 플레이트(120)의 록킹홈(121)에 결합됨으로써 도어측 플레이트(120)와 함께 고정핀(130)을 중심으로 회동된다.That is, the locking protrusion 131 protruding in the middle of the fixing pin 130 is coupled to the locking groove 121 of the door side plate 120 to rotate about the fixing pin 130 together with the door side plate 120. do.

상기 고정핀(130)의 중간은 절단되어 있으며, 절단된 부분의 양 끝단에는 스프링(132)이 연결되어 있다. 따라서, 스프링(132)의 탄발력에 의해서 고정핀(130)은 차체측 플레이트(110)와 도어측 플레이트(120)를 탄력적으로 결합시키고 있다.The middle of the fixing pin 130 is cut, the spring 132 is connected to both ends of the cut portion. Therefore, the fixing pin 130 elastically couples the vehicle body side plate 110 and the door side plate 120 by the spring force of the spring 132.

고정핀(130), 보다 정확하게는 고정핀(130)의 머리부(130a)와 접하는 도어측 플레이트(120)에는 원주방향을 따라 굴곡면(122)이 형성되어 있고, 고정핀(130)의 머리부(130a)에는 굴곡면(122)을 따라 슬라이드 이동되는 돌기(133)가 형성되어 있다.The fixing pin 130, more precisely, the door side plate 120 in contact with the head 130a of the fixing pin 130 is formed with a curved surface 122 in the circumferential direction, the head of the fixing pin 130 The projection 130 is slid along the curved surface 122 in the portion 130a.

이와 같이 구성된 본 발명에 따른 자동차 도어 힌지의 작용을 설명하면 다음과 같다.Referring to the operation of the vehicle door hinge according to the present invention configured as described above are as follows.

도 4 및 도 5에 나타낸 바와 같이, 도어(2)를 열고 닫으면 도어측 플레이트(120)와 결합되어 있는 고정핀(130)은 회동된다.4 and 5, when the door 2 is opened and closed, the fixing pin 130 coupled to the door side plate 120 is rotated.

스프링(132)에 의하여 고정핀(130)의 돌기(133)가 도어측 플레이트(120)의 굴곡면(122)에 탄력적으로 접하고 있기 때문에 도어측 플레이트(120)가 회동되면, 돌기(133)가 굴곡면(122)을 따라 슬라이드 이동되며 이때, 도어(2)가 일정 한계 이상으로 개방되거나 또는 완전히 개방된 지점에서, 사람의 힘에 의하지 아니하고는 그 자력으로 닫히거나 열리지 않게 된다.Since the protrusion 133 of the fixing pin 130 is elastically in contact with the curved surface 122 of the door side plate 120 by the spring 132, when the door side plate 120 is rotated, the protrusion 133 is rotated. The slide is moved along the curved surface 122, at which point the door 2 is opened or completely opened beyond a certain limit, the magnetic force is not closed or opened except by the force of the person.

즉, 돌기(133)가 탄력적으로 굴곡면(122)에 접촉된 상태에서 굴곡면(122)을 타넘으면서 이동되기 때문에 자동차가 경사면에 정차한 상태에서 도어를 열 때에도 도어가 임의로 확 젖혀지거나 닫혀지지 않게 된다.That is, since the protrusion 133 is moved while crossing the curved surface 122 in a state in which the protrusion 133 is elastically contacted with the curved surface 122, the door is not flipped or closed arbitrarily even when the door is opened while the vehicle is stopped on the inclined surface. Will not.

이상과 같이 본 발명은 고정핀(130)이 삽입되는 부위에 굴곡면(122)과 이 굴곡면(122)을 따라 탄력적으로 슬라이드 이동되는 돌기(133)를 형성하여 도어(2)가 개폐될 때 고정핀(130)에 의해서 회동되면서 개폐될 수 있음은 물론 돌기(133)가 굴곡면(122)에 접촉되어 슬라이드 이동됨으로써 도어(2)가 단계적으로 열릴 수 있다.As described above, the present invention forms a curved surface 122 and a protrusion 133 that is elastically slid along the curved surface 122 at a portion into which the fixing pin 130 is inserted when the door 2 is opened and closed. The door 2 may be opened in stages by being able to be opened and closed while being rotated by the fixing pin 130 as well as the protrusion 133 slides in contact with the curved surface 122.

이와 같이 본 발명은 도어체커를 사용하지 않으므로 부품 및 제조공정을 줄일 수 있으며, 경량화를 실현하고 제조원가를 대폭적으로 감소시킬 수 있다.As described above, the present invention does not use the door checker, thereby reducing parts and manufacturing processes, realizing light weight, and significantly reducing manufacturing costs.

또한, 본 발명은 전체 구성이 매우 단순하면서도 작동이 원활하고 성능이 뛰어난 효과가 있다.In addition, the present invention has the effect that the overall configuration is very simple yet smooth operation and excellent performance.
