본 고안은 자동차의 도어 임팩트 빔 부착구조에 관한 것이다.The present invention relates to a door impact beam attachment structure of a vehicle.

자동차의 도어는 도어 아웃터 패널과 도어 인너 패널을 도어 윈도우 오프닝 기구를 내장하는 공동부가 형성되게 그 양측면과 저면을 결합한 것이므로 자동차의 측면 충돌시에 도어가 실내로 과도하게 침입하여 탑승자의 골반부분의 상해치가 크게되기 대문에 상기 공동부에 도어 아웃터패널에 밀착시키거나 근접되게 도어 임팩트 빔을 설치하여 도어의 강성을 증대시켜 탑승자의 안전성을 증대시키고 있다.The door of the car is a combination of both sides and the bottom of the door outer panel and the door inner panel to form a cavity that contains the door window opening mechanism. As the teeth become larger, the door impact beam is installed in close contact with or close to the door outer panel to increase the rigidity of the door, thereby increasing the occupant safety.

그러나 종래의 도어 임팩트 빔은 제4도에 도시한 바와 같이 도어(1)의 도어 아웃터 패널(20과 도어 인너 패널(3) 사이에 형성된 공동부(4)에 가로로 도어 임팩트 빔(5)을 그 양단의 면에 용접 고정한 브래킷(6)으로 도어 인너 패널(3)(도어 힌지 설치 부위는 도어 힌지 페이스)에 용접 고정하여서 도어(1)에 충격력이 가하여지면 도어 임팩트 빔(5)과 브래킷(6)에 의한 강성증대에 의하여 도어(1)의 변형이 억제되면서 충격력을 흡수하도록 되어 있다.However, the conventional door impact beam has the door impact beam 5 transverse to the cavity 4 formed between the door outer panel 20 and the door inner panel 3 of the door 1 as shown in FIG. When the impact is applied to the door 1 by welding and fixing it to the door inner panel 3 (door hinge installation site is the door hinge face) with the bracket 6 welded to both sides thereof, the door impact beam 5 and the bracket ( 6) the deformation of the door 1 is suppressed by the increase in rigidity, so as to absorb the impact force.

그렇지만 통상적으로 도어 임팩트 빔(5)은 고장력 파이프로 제작하는데 대하여 브래킷(6)은 탄소강판 등으로 만들므로서 자동차의 측면 충돌시에 도어 임팩트 빔(5) 보다 브래킷(6)의 변형이 심하여 도어 임팩트 빔(5)이 가지고 있는 강성을 유효하게 활용하지 못하고 브래킷(6)이 변형될 때 종래의 브래킷(6)은 도어 임팩트 빔(5)의 외면에 탄산가스 용접 고정한 것이므로 용접 고정부가 파손되어서 도어 임팩트 빔(5)의 충격 흡수기능이 상실되는 문제점이 있는 것이다.In general, however, the door impact beam 5 is made of high-strength pipe, but the bracket 6 is made of carbon steel plate, and thus the deformation of the bracket 6 is more severe than that of the door impact beam 5 during the side impact of the vehicle. When the bracket 6 is deformed when the impact beam 5 does not effectively utilize the rigidity of the impact beam 5, the conventional bracket 6 is carbon dioxide gas fixed to the outer surface of the door impact beam 5, so that the welding fixing part is broken and the door There is a problem in that the impact absorption function of the impact beam 5 is lost.

본 고안은 상기한 문제점을 시정하여 도어 임팩트 빔이 가지고 있는 강성을 유효하게 이용하여 충격 흡수기능을 양호하게 수행할 수 있도록 한 자동차의 도어 임팩트 빔 부착구조를 제공하는 것을 목적으로 한다.The object of the present invention is to provide a door impact beam attachment structure for a vehicle that can effectively perform the shock absorbing function by effectively using the stiffness of the door impact beam by correcting the above problems.

본 고안은 상기한 목적을 달성하기 위하여 도어 아웃터 패널과 도어 인너 패널 사이에 형성된 공동부에 가로로 설치되는 도어 임팩트 빔의 양단부를 가압 성형하여 도어 임팩트 빔과 일체로 편평한 고정부를 형성하여서 상기 고정부를 도어 인너 패널에 탄산가스 용접 고정한 것이다.The present invention is formed by pressing both ends of the door impact beam horizontally installed in the cavity formed between the door outer panel and the door inner panel to achieve the above object to form a flat fixing unit integrally with the door impact beam The government welded carbon dioxide to the door inner panel.

이하 실시예를 도면에 의하여 설명한다.Embodiments will be described below with reference to the drawings.

본 고안은 제1도 내지 제3도에 도시한 바와 같이 도어(1)의 도어 아웃터 패널(2)과 도어 인너 패널(3) 사이에 형성된 공동부(4)에 가로로 도어 아웃터 패널(2)에 실러로 접착하거나 근접시켜 설치되는 도어 임팩트 빔(5)의 양단부를 단조 등의 방법으로 가압 성형하여 도어 임팩트 빔(5)과 일체로 편평한 고정부(7)를 형성하여서 상기 고정부(7)를 도어 인너 패널(2)(도어 힌지 부위는 도어 힌지 페이스)에 탄산가스 용접 결합한 것이다.According to the present invention, as shown in FIGS. 1 to 3, the door outer panel 2 is disposed horizontally in a cavity 4 formed between the door outer panel 2 and the door inner panel 3 of the door 1. The end portions of the door impact beams 5 which are installed by adhering or adhering to the sealer by means of forging or the like to form a flat fixing portion 7 integrally with the door impact beams 5, for example. To the door inner panel 2 (door hinge portion is the door hinge face) is a carbon dioxide gas welding coupling.

이상과 같은 본 고안은 도어 임팩트 빔(5)과의 양단부에 형성되는 편평한 고정부(7)는 도어 임팩트 빔(5)을 가압 성형하여 도어 임팩트 빔(5)과 일체로 형성한 것이므로 도어 임팩트 빔(5)과 고정부(7)의 단면계수가 동일하여 강성이 동일하기 때문에 자동차의 측면 충돌시에 도어 임팩트 빔(5)이 가지고 있는 강성을 유효하게 이용하게 되어 충격흡수가 양호하여 탑승자의 안전성이 증대되고 종래 도어 임팩트 빔(5)에 별도의 브래킷을 용접하던 것에 비하여 공차 관리가 편리할 뿐 아니라 원가를 절감할 수 있으며, 고정부(7)를 도어 인너패널(3)에 탄산가스 용접하므로서 용접 강도도 확보되는 등의 효과가 있는 것이다.The present invention as described above is a flat fixing portion 7 formed on both ends of the door impact beam 5 is formed by pressing the door impact beam 5 integrally with the door impact beam 5, so the door impact beam Since the cross-sectional coefficients of (5) and the fixing part (7) are the same, the rigidity of the door impact beam (5) is effectively used during side impact of the vehicle. Compared to the conventional welding of a separate bracket to the door impact beam (5), the tolerance management is convenient and the cost can be reduced, and the fixing part (7) is welded to the door inner panel (3) by carbon dioxide gas. The welding strength is also secured.
