도어 패널 구조{Door panel structure}Door panel structure

본 발명은 도어 패널 구조에 관한 것으로서, 특히 차량의 측면 충돌 시 도어아우터패널의 헤밍부가 이탈하게 되는 현상을 방지하고 도어 패널의 강성을 확보할 수 있게 하기 위한 도어 패널 구조에 관한 것이다.The present invention relates to a door panel structure, and more particularly, to a door panel structure for preventing a phenomenon in which a hemming portion of the door outer panel is detached when a vehicle collides with a side surface and securing rigidity of the door panel.

일반적으로 차량용 도어는 아우터패널과 이너패널로 이루어지게 되는데 아우터패널에는 벨트레일 아우터와 벨트몰딩이 결합되어 도어 글라스를 지지하고, 벨트레일 아우터의 경우 이너패널에 용접되어 부착되고 아우터패널과는 헤밍작업으로 결합된다.In general, a door for a vehicle is made of an outer panel and an inner panel. A belt rail outer and a belt molding are coupled to the outer panel to support the door glass. Are combined into.

그러나, 종래에는 도 1에 도시된 바와 같이 아우터패널(20)과 이너패널(10)의 결합력이 부족하여 측면 충돌 발생 시 헤밍부가 이탈하게 되고 이로 인해 도어 문이 열리게 되어 충돌법규를 만족하지 못하게 된다.However, in the related art, as shown in FIG. 1, the coupling force between the outer panel 20 and the inner panel 10 is insufficient, and when a side collision occurs, the hemming part is disengaged, which causes the door door to be opened, thereby failing to satisfy the collision law. .

또한, 침입량이 증가하게 되며 도어 트림 샤프 엣지가 발생하게 되고, 헤밍두께가 얇아 파팅라인이 샤프해 강성이 저하되는 문제점이 있었다.In addition, there was a problem in that the amount of intrusion increases, a sharp edge of the door trim occurs, and the hemming thickness is thin, so the parting line is sharp and the rigidity is reduced.

본 발명의 실시예를 첨부 도면을 참조하여 상세히 설명하면 다음과 같다.If described in detail with reference to the accompanying drawings, an embodiment of the present invention.

본 발명의 도어 패널 구조는 도 2 및 도 3에 도시된 바와 같이, 도어이너패널(100) 양단에 헤밍(100H)이 형성되며, 도어아우터패널(200) 양단에도 헤밍(200H)이 형성되어 도어이너패널(100) 양단의 헤밍(100H)에 도어아우터패널(200) 양단의 헤밍(200H)이 겹쳐지게 형성되는 것을 특징으로 한다.2 and 3, a hemming 100H is formed at both ends of the door inner panel 100, and a hemming 200H is formed at both ends of the door outer panel 200 as well. It is characterized in that the hemming (200H) at both ends of the door outer panel (200) overlaps the hemming (100H) at both ends of the inner panel (100).

도 2, 도 4 및 도 6에 도시된 바와 같이, 도어이너패널(100)은 양단(A필라 측과 B필라 측)이 도어(1) 내측 방향으로 헤밍(100H)이 형성된다.2, 4 and 6, the door inner panel 100 has both ends (A-pillar side and B-pillar side) in which the hemming 100H is formed in the door 1 inner direction.

이때, 도어아우터패널(200)도 양단에 헤밍(200H)이 형성되는데 도어아우터패널(200)의 헤밍(200H) 위치는 도어이너패널(100) 양단에 형성된 헤밍(100H) 상부에 형성되어 이중 헤밍 구조를 형성하게 된다.At this time, the door outer panel 200 is also formed with a hemming (200H) at both ends, the position of the hemming (200H) of the door outer panel (200) is formed on the hemming (100H) formed on both ends of the door inner panel (100H) double hemming To form a structure.

보다 자세하게는 도어아우터패널(200)의 양단이 도어이너패널(100)의 양단을 커버하는 형상으로 이루어지도록 하여 도어이너패널(100)과 도어아우터패널(200)이 헤밍(200H)에 의해 결합되게 함으로써 패널 두께가 증가하게 되어 도어(1) 패널의 강성을 향상시킬 수 있게 한다.In more detail, both ends of the door outer panel 200 are formed to cover both ends of the door inner panel 100 so that the door inner panel 100 and the door outer panel 200 are coupled by the hemming 200H. By doing so, the panel thickness increases, so that the rigidity of the door 1 panel can be improved.

한편, 도 4에 도시된 바와 같이 도어이너패널(100)의 A필라 측에 걸림홀(110)이 형성되게 하여 도어아우터패널(200)과 결합될 수 있게 한다.Meanwhile, as illustrated in FIG. 4, the locking hole 110 is formed on the A pillar side of the door inner panel 100 so that it can be combined with the door outer panel 200.

또한, 도 5에 도시된 바와 같이 도어이너패널(100) 하부 측에도 걸림홀(110)이 형성되게 하여 드레인홀로 사용될 수 있게 하는 것이 바람직하다.In addition, as shown in FIG. 5, it is preferable that the locking hole 110 is formed on the lower side of the door inner panel 100 so that it can be used as a drain hole.

도 7에 도시된 바와 같이 도어아우터패널(200) 양단 끝단에는 후크형 플랜지(210)가 형성되어 도어이너패널(100)에 대응할 수 있게 하는 것이 바람직하다.As illustrated in FIG. 7, it is preferable that hook-type flanges 210 are formed at both ends of the door outer panel 200 so as to correspond to the door inner panel 100.

이때, 도어이너패널(100)의 후크형 플랜지(210) 끝단은 도어이너패널(100)의 A필라 측에 형성된 걸림홈에 삽입되도록 하여 도어이너패널(100)과 도어아우터패널(200)의 결합력을 향상시킬 수 있게 한다.At this time, the end of the hook-type flange 210 of the door inner panel 100 is inserted into a locking groove formed on the A-pillar side of the door inner panel 100 so that the coupling force between the door inner panel 100 and the door outer panel 200 To improve.

즉, 본 발명은 도 8에 도시된 바와 같이 도어아우터패널(200)의 헤밍(200H) 굴절이 완료 되기 전에는 끝단에 후크형 플랜지(210)만 형성된 상태로 구비되며, 도어아우터패널(200)을 굴절시키게 되면 도어(1) 내측으로 헤밍(200H)이 형성된 도어이너패널(100)을 커버하여 이중 헤밍 구조를 형성하게 된다.That is, the present invention is provided in a state in which only the hook-type flange 210 is formed at the end before the hemming (200H) refraction of the door outer panel 200 is completed, as shown in FIG. 8, and the door outer panel 200 is provided. When refracted, the door inner panel 100 having the hemming 200H formed inside the door 1 is covered to form a double hemming structure.

그 결과, 도어이너패널(100)과 도어아우터패널(200)의 두께가 증가하게 되어 도어(1) 패널의 외관 강성을 향상시키게 되고, 또한 도어아우터패널(200) 헤밍(210H) 시 도어아우터패널(200)의 후크형 플랜지(210)가 도어이너패널(100)의 걸림홀(110)에 삽입되어 차량 충돌 발생 시 도어아우터패널(200)의 헤밍(200H)이 도어이너패널(100)로부터 이탈되는 것을 방지하여 도어(1) 패널이 열리게 되는 현상을 방지함으로써 충돌법규를 만족시키고 안전성과 상품성을 증대시키게 된다.
As a result, the thickness of the door inner panel 100 and the door outer panel 200 increases, thereby improving the appearance rigidity of the door 1 panel, and also when the door outer panel 200 hemming 210H, the door outer panel When the hook-type flange 210 of 200 is inserted into the locking hole 110 of the door inner panel 100, the hemming 200H of the door outer panel 200 deviates from the door inner panel 100 when a vehicle crashes. It prevents the door 1 panel from being opened, thereby satisfying the collision law and increasing safety and productability.

이상과 같이, 본 발명은 비록 한정된 실시예와 도면에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않으며 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술사상과 아래에 기재될 특허청구범위 내에서 다양한 수정 및 변형이 가능함은 물론이다.
As described above, although the present invention has been described by a limited number of embodiments and drawings, the present invention is not limited by this, and the technical idea of the present invention and the following will be described by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of the claims to be described.
