본 발명은 자동차의 도어 임팩트 빔 부착구조에 관한 것이다.The present invention relates to a door impact beam attaching structure of an automobile.

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 크게 되기 때문에 상기 공동부에 도어 아웃터 패널에 밀착시키거나 근접되게 도어 임팩트 빔을 설치하며 도어의 강성을 증대시켜 탑승자의 안전성을 증대시키고 있다.Since the door of the automobile is a combination of the both sides and the bottom surface of the door outer panel and the door inner panel so as to form a cavity including a door window opening mechanism, the door is excessively infiltrated into the room during a side collision of the vehicle, The door impact panel is installed close to the door outer panel or the door impact beam is installed close to the cavity, thereby increasing the rigidity of the door, thereby enhancing the safety of the passenger.

그러나 종래의 도어 임팩트 빔은 제1도에서 참조되고 제4도 및 제5도에 도시한 바와 같이 도어(1)의 도어 아웃터 패널(2)과 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.The conventional door impact beam, however, is referred to in FIG. 1 and is provided with a cavity 4 formed between the door outer panel 2 of the door 1 and the door inner panel 3, as shown in FIGS. The door inner panel 3 (the door hinge mounting portion is a door hinge face) is welded and fixed to the door 1 by means of the bracket 6 welded and fixed to both sides of the lateral impact impact beam 5 on the door 1, The deformation of the door 1 is suppressed by increasing the rigidity by the door impact beam 5 and the bracket 6 so that the impact force is absorbed.

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 많게 되는 바, 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.However, since the door impact beam 5 is generally made of a high-strength pipe, the bracket 6 is made of a carbon steel plate or the like, so that the deformation of the bracket 6 is greater than that of the door impact beam 5 When the bar and bracket 6 are deformed, the conventional bracket 6 is welded and fixed to the outer surface of the door impact beam 5 by carbonic acid gas welding, so that the welding fixture is broken and the impact absorption function of the door impact beam 5 is lost .

본 발명은 상기한 문제점을 시정하여 도어 임팩트 빔과 브래킷을 견고하게 결합하여 충격 흡수기능을 양호하게 수행할 수 있도록 한 자동차의 도어 임팩트 빔 부착구조를 제공하는 것을 목적으로 한다.SUMMARY OF THE INVENTION It is an object of the present invention to provide a structure for attaching a door impact beam to an automobile in which a door impact beam and a bracket are rigidly coupled to each other by correcting the above-mentioned problems.

본 발명은 상기한 목적을 달성하기 위하여 도어 아웃터 패널과 도어 인너 패널사이에 형성된 공동부에 가로로 설치되는 도어 임팩트 빔의 양단에 대칭되는 슬릿을 형성하여 브래킷을 도어 임팩트 빔의 내면을 관통시켜 상기 슬릿에 돌출되게 끼워서 상호 용접 고정한 후 도어 인너 패널에 결합한 것이다.In order to achieve the above-mentioned object, the present invention provides a door impact device for a vehicle, comprising: a door impact panel having slits symmetrically formed at both ends of a door impact beam horizontally installed in a cavity formed between a door outer panel and a door inner panel, Protruding from the slit, welded to each other, and then joined to the door inner panel.

이하 실시예를 도면에 의하여 설명한다.Hereinafter, embodiments will be described with reference to the drawings.

본 발명은 제1도 내지 제4도에 도시한 바와 같이 도어(1)의 도어 아웃터 패널(2)과 도어 인너 패널(3) 사이에 형성된 공동부(4)에 도어 아웃터 패널(2)에 실러로 접착하거나 근접시켜 가로로 설치되는 도어 임팩트 빔(5)의 양단에 상하 대칭되는 슬릿(11)(11')을 형성하고, 브래킷(6)에 도어 임팩트 빔(5)의 내경과 동일한 곡률반경을 가진 호상의 돌출부(12)를 형성하여 상기 돌출부(13)를 도어 임팩트 빔(50)의 내주면에 밀착시킴과 동시에 브래킷(12)의 상하단을 슬릿(11)(11')에 끼워서 외부로 돌출시킨후 상호 탄산가스 용접 결합하고 브래킷(12)의 하단을 도어 인너 패널(3)(도어 힌지 설치부위는 도어 힌지 페이스)에 용접 결합한 것이다.The present invention is characterized in that the door outer panel 2 is sealed by a hollow portion 4 formed between the door outer panel 2 of the door 1 and the door inner panel 3 as shown in Figs. (11) and (11 ') symmetrical to each other at both ends of a door impact beam (5) installed side by side with the door impact beam (5) And the projection 13 is brought into close contact with the inner peripheral surface of the door impact beam 50 and the upper and lower ends of the bracket 12 are inserted into the slits 11 and 11 ' Welded to each other, and the lower end of the bracket 12 is welded to the door inner panel 3 (the door hinge mounting portion is a door hinge face).

이상과 같은 본 발명은 도어 임팩트 빔(5)에 브래킷(12)을 고정할 때 브래킷(12)에 형성된 호상 돌출부(13)를 도어 임팩트 빔(5)의 내주면에 밀착시킴과 동시에 그 상하단을 도어 임팩트 빔(5)의 양단에 형성한 슬릿(11)(11')에 돌출되게 끼운 다음 상호 탄산가스 용접 고정하여 결합력을 증대시키므로서 도어(1)에 충격력이 가하여져서 도어 임팩트 빔(5)과 브래킷(12)에서 충격력을 흡수할 때 도어 임팩트 빔(5)이 브래킷(12)에서 탈락되는 것이 방지되어서 충격 흡수 기능을 양호하게 수행하는 것이다.The present invention as described above makes it possible to bring the arc-shaped projection 13 formed on the bracket 12 into close contact with the inner peripheral surface of the door impact beam 5 when the bracket 12 is fixed to the door impact beam 5, The door 1 is impacted with the door impact beam 5 by being welded to the slits 11 and 11 'formed at both ends of the impact beam 5, The door impact beam 5 is prevented from falling off the bracket 12 when the impact force is absorbed by the bracket 12, thereby performing the shock absorbing function well.

이상과 같이 본 발명은 도어 임팩트 빔의 양단에 슬릿을 형성하여 브래킷을 도어 임팩트 빔의 내주면에 밀착시킴과 동시에 슬릿에 끼워 돌출시킨 다음 상호 용접 고정한 것이므로 결합력이 증대되어서 측면 충돌시에 도어 임팩트 빔이 브래킷에서 탈락되는 것을 방지하므로서 충격 흡수기능을 양호하게 수행할 수 있는 효과가 있는 것이다.As described above, according to the present invention, the slit is formed at both ends of the door impact beam so that the bracket is brought into close contact with the inner peripheral surface of the door impact beam, It is possible to prevent the bracket from being detached from the bracket so as to perform the shock absorbing function satisfactorily.
