In the impact beam 5, which is mounted by a bracket 3 on the inner side of the inner side of the door 1 in order to achieve, the impact beam 5 forms a rhombus and flanges to the hollow part 5c. (5a) (5a ') is formed and attached to the inner wall of the hollow part 5c which opposes through the return spring 5b, 5b' at the front-end | tip of the said flange part 5a, 5a '. It features.

상기한 구성에 의하면, 측면 충돌시 도어의 중앙부분이 받는 큰 충격을 마름모형상의 임팩트 빔(5)이 충격을 최대한으로 흡수하는 동시에, 그 임팩트 빔(5)의 변형시 충격을 중공부(5c)내의 플랜지부(5a)(5a')에 장착된 리턴 스프링(5b)(5b')의 완충작용에 의하여 거의 흡수한다.According to the above-described configuration, the impact beam 5 of the rhombus absorbs the impact to the greatest extent while the central portion of the door is subjected to a large impact at the time of the side collision, and the impact at the time of deformation of the impact beam 5 is the hollow portion 5c. Absorption is almost carried out by the buffering action of the return springs 5b and 5b 'attached to the flange portions 5a and 5a' in the inner side.

따라서, 본 고안에 의하면, 측면 충돌시 도어가 받는 충격을 마름모형상의 임팩트 빔과 그 중공부내 플랜지부에 장착되어 있는 리턴 스프링이 효과적으로 흡수하여 차체의 손상을 최소화하여 충격이 실내로 밀려 들어오는 것을 방지하여 실내 탑승객의 최대한으로 보호할 수 있는 유용한 고안이다.Therefore, according to the present invention, the impact received by the door during side impact is effectively absorbed by the rhombus-shaped impact beam and the return spring mounted on the flange portion of the hollow part, thereby minimizing damage to the vehicle body and preventing the impact from being pushed into the room. It is a useful design that can protect the maximum number of passengers indoors.

Description

도어 임팩트 빔 구조Door impact beam structure

본 고안은 도어 임팩트 빔 구조에 관한 것으로, 특히 측면 충돌시 충격을 보다 효과적으로 흡수하여 도어의 손상을 최소화하고 충격이 실내로 유입되는 것을 최대한으로 방지할 수 있는 임팩트 빔의 개선에 관한 것이다.The present invention relates to a door impact beam structure, and more particularly, to improve impact beams that can effectively absorb shocks during side impacts to minimize damage to doors and prevent shocks from entering the room.

일반적으로 원형상의 임팩트 빔(4)은 도 1 및 도 2에 도시한 바와 같이 양단이 브래킷(3)으로 지지되어 도어 인너 패널(1)에 장착되어 있고 이 도어 인너 패널(1)은 도어 아우터 패널(2)와 접합되어 있다.In general, the circular impact beam 4 is mounted on the door inner panel 1 with both ends supported by the bracket 3 as shown in FIGS. 1 and 2, and the door inner panel 1 is a door outer panel. It is joined with (2).

이러한 임팩트 빔(4)은 측면 충돌시 충격을 완벽하게 흡수할 수 없기 때문에 그때의 충격으로 도어의 손상이 크고 도어가 실내로 많이 유입되어 실내 탑승객에게 치명적인 상해를 입히는 등의 문제점이 있었다.Since the impact beam 4 cannot completely absorb the impact at the time of the side impact, the damage of the door is large due to the impact at that time, and the door is introduced into the interior, causing serious injury to the passengers.

본 고안은 상기한 문제점을 감안하여 안출된 것으로서, 측면 충돌시 충격을 최대한으로 흡수하여 차체의 손상을 최소화하고 도어의 측면이 실내로 밀려 들어오는 것을 효과적으로 방지하여 실내 탑승객의 최대한으로 보호할 수 있는 도어 임팩트 빔 구조를 제공하는 것을 과제로 한다.The present invention is conceived in view of the above problems, the maximum impact in the event of a side collision to minimize damage to the vehicle body and effectively prevent the door side from being pushed into the interior door to protect the maximum number of passengers An object of the present invention is to provide an impact beam structure.

상기한 과제를 달성하기 위한 본 고안의 구성 및 작용을 첨부도면에 의거하여 상세히 설명하면 다음과 같다.Referring to the configuration and operation of the present invention for achieving the above problems in detail based on the accompanying drawings as follows.

통상의 도어 인너 내측(1)면에 브래킷(3)에 의해 장착되어 있는 임팩트 빔(5)에 있어서, 상기 임팩트 빔(5)은 마름모형상을 이루며 그 중공부(5c)에 플랜지부(5a) (5a')가 형성되고, 상기 플랜지부(5a)(5a')의 선단에 리턴 스프링(5b)(5b')을 개재하여 대향하는 중공부(5c)의 내벽에 장착하여 구성된 것을 특징으로 한다.In the impact beam 5 mounted by the bracket 3 on the inner side of the inner side of the inner door 1, the impact beam 5 forms a rhombus shape and the flange portion 5a on the hollow portion 5c. 5a 'is formed, and is mounted on the inner wall of the opposing hollow portion 5c via return springs 5b and 5b' at the ends of the flange portions 5a and 5a '. .

상기한 구성에 의하면, 측면 충돌시 도어의 중앙부분이 받는 큰 충격을 마름모형상의 임팩트 빔(5)이 충격을 최대한으로 흡수하는 동시에, 그 임팩트 빔(5)의 변형시 충격을 중공부(5c)내의 플랜지부(5a)(5a')에 장착된 리턴 스프링(5b)(5b')의 완충작용에 의하여 거의 흡수한다.According to the above-described configuration, the impact beam 5 of the rhombus absorbs the impact to the greatest extent while the central portion of the door is subjected to a large impact at the time of the side collision, and the impact at the time of deformation of the impact beam 5 is the hollow portion 5c. Absorption is almost carried out by the buffering action of the return springs 5b and 5b 'attached to the flange portions 5a and 5a' in the inner side.

이상 설명한 바와 같이, 본 고안에 의하면, 측면 충돌시 도어가 받는 충격을 마름모형상의 임팩트 빔과 그 중공부내 플랜지부에 장착되어 있는 리턴 스프링이 효과적으로 흡수하여 차체의 손상을 최소화하여 충격이 실내로 밀려 들어오는 것을 방지하여 실내 탑승객의 최대한으로 보호할 수 있는 유용한 고안이다.As described above, according to the present invention, the impact received by the door during side impact is effectively absorbed by the rhombus-shaped impact beam and the return spring mounted on the flange portion of the hollow portion, thereby minimizing damage to the vehicle body, and the impact is pushed into the room. It is a useful design that can prevent the coming in and protect the occupants as much as possible.
