본 고안은 자동차 범퍼의 완충 장치에 관한 것으로서, 특히 자동차의 충돌시 범퍼 스테이와 결합된 사이드 멤버 내에 질소 가스 충진된 캡슐의 폭발로 완충력이 발생되도록 한 것이다.The present invention relates to a shock absorber of an automobile bumper, and in particular, a shock force is generated by explosion of a nitrogen gas filled capsule in a side member coupled with a bumper stay during a collision of an automobile.
자동차 범퍼의 완충 장치에는 여러 가지 구성에 의한 완충 장치가 있으나 대부분이 기계적 구성(예 : 5마일 범퍼)에만 의존되어 있었으며, 이러한 기계적 구성으로는 자동차의 충돌 등에 의한 완충 효과를 어느 정도 기대할 수 있었으나, 기계적 구성만으로 이루어진 완충 장치의 실질적인 완충 효과는 가스를 이용한 완충력에 월등히 못미치는 것이 사실이다.The shock absorbers of automobile bumpers have various shock absorbers, but most of them depend only on mechanical components (e.g., 5 mile bumpers). It is true that the shock absorbing effect of the shock absorber, which is composed only of mechanical construction, is much lower than that of gas.
따라서, 본 고안에서는 질소 가스를 이용하여 자동차의 충돌에 따른 완충 효과가 발생될 수 있도록 한 것으로 완충재 및 범퍼빔을 가지는 범퍼 커버와 사이드 멤버의 사이에 설치되는 범퍼 스테이를 포밍된 원추형으로 하여서 그 내부에 공이를 가지는 피스톤 파이프가 설치되도록 하고, 상기 파이프가 삽입 설치되는 사이드 멤버의 선단 내부에는 질소 가스가 충전된 소형의 캡슐을 설치하여서 충돌과 동시에 피스톤 파이의 공이가 상기 질소 캡슐을 터트리게 하므로써, 순간적으로 유출된 질소 가스로 인한 완충이 이루어지도록 한 것이다.Therefore, in the present invention, the shock absorbing effect of the collision of the vehicle is generated by using nitrogen gas, and the bumper stay installed between the bumper cover having the shock absorber and the bumper beam and the side member is formed into a conical shape. By installing a piston pipe having a ball on the inside of the end member of the side member in which the pipe is inserted, by installing a small capsule filled with nitrogen gas so that the ball of the piston pie bursts the nitrogen capsule at the same time, The buffer is caused by the nitrogen gas leaked out momentarily.
이하 첨부 도면을 참고하여 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 완충재(1) 및 범퍼빔(2)을 가지는 범퍼커버(3)와 사이드 멤버(4)의 사이에 범퍼 스테이(5)가 설치되어서 이루어진 자동차 범퍼의 완충 장치(6)에 있어서, 상기 범퍼 스테이(5)는 포밍부(5')를 가지는 원추형으로 이루어지는 동시에 그 내부에 공이(7)를 가지는 피스톤 파이프(8)가 설치되고 사이드 멤버(5) 내에는 공이(7)의 끝단과 근접되도록 질소 가스 충전된 캡슐(9)을 고정 설치하여서 이루어진 것이다.According to the present invention, in the bumper shock absorber (6) of the automobile bumper, wherein the bumper stay (5) is provided between the bumper cover (3) having the shock absorbing material (1) and the bumper beam (2) and the side member (4). The bumper stay 5 has a conical shape with a forming portion 5 'and a piston pipe 8 having a ball 7 therein is provided and within the side member 5 is close to the end of the ball 7. It is made by fixing the nitrogen gas filled capsule (9) as possible.
본 고안을 좀 더 상세히 설명하면 다음과 같다.The present invention is described in more detail as follows.
첨부 도면 제1도는 본 고안의 분리 사시도로서, 자동차용 범퍼는 완충재(1)와 범퍼빔(2)이 나란히 내설되고, 이를 덮고 있는 범퍼 커버(3)로 구성되어 있는 바, 상기 범퍼빔(2)과 사이드 멤버(4)의 사이에 범퍼 스테이(5)를 설치하되, 상기 범퍼 스테이(5)의 전면은 상기 범퍼빔(2)에 용접으로 고정되고, 외주에 주름형의 포밍부(6)가 형성된 원추형으로써, 내부에는 후단에 공이(7)가 형성된 피스톤 파이프(8)가 용접(10)으로 고정 설치된다.1 is an exploded perspective view of the present invention, wherein the bumper for automobile is composed of a bumper cover 3 having a cushioning material 1 and a bumper beam 2 arranged side by side, and covering the bar bumper beam 2. The bumper stay 5 is installed between the side member 4 and the front side of the bumper stay 5 by welding to the bumper beam 2, and a corrugated forming part 6 is formed on the outer circumference thereof. As the conical shape is formed, the piston pipe 8 formed with the ball 7 at the rear end is fixedly installed by welding (10).
또한 상기 사이드 멤버(4)의 내부에는 질소가 충진된 질소 캡슐(9)이 사이드 멤버(4)의 내경을 밀폐하도록 고정 설치 되어져 있다.In addition, a nitrogen capsule 9 filled with nitrogen is fixedly installed in the side member 4 to seal the inner diameter of the side member 4.
또한 상기 피스톤 파이프(8)의 공이(7) 끝을 질소 캡슐(9)이 여러번의 충격 실험을 통해 사이드 멤버(4)에 전해지는 충격량이 최소가 되기 이전에 터질 수 있도록 질소캡슐(9)에 근접되도록 삽입하는 동시에 상기 범퍼 스테이(5)의 후면과 상기 사이드 멤버(4)는 용접(10)으로 고정된다.In addition, the end of the ball (7) of the piston pipe (8) to the nitrogen capsule (9) so that the nitrogen capsule (9) can burst before the minimum amount of impact transmitted to the side member (4) through a number of impact experiments The rear surface of the bumper stay 5 and the side member 4 are fixed by welding 10 while being inserted close together.
따라서 차량의 충돌에 의하여 범퍼(3)가 후진되어지면 범퍼빔(2)의 포밍부(6)가 자바라가 압축되듯이 압착되어지며 공이(7)가 질소 캡슐(9)의 전면에 맞닿아 이를 터트리면서 질소 캡슐(9)의 폭발이 이루어지고, 이 폭발력으로 후진되어진 범퍼 스테이(5)내의 피스톤 파이프(8)가 순간적으로 피스톤의 역할을 하며 범퍼(3)와 함께 전방으로 진출되므로써, 완충력과 함께 상당한 복원력을 발휘하게 되는 것이다.Therefore, when the bumper 3 is reversed due to the collision of the vehicle, the forming part 6 of the bumper beam 2 is compressed as if the bellows is compressed, and the ball 7 contacts the front surface of the nitrogen capsule 9. The explosion of the nitrogen capsule 9 takes place while the piston pipe 8 in the bumper stay 5, which has been reversed by this explosive force, acts as a piston momentarily and advances forward with the bumper 3, thereby providing a cushioning force. It will be a significant resilience.
이상 상술한 바와같이 본 고안은 질소 가스가 충전된 캡슐을 이용하여 가스압에 의한 폭발로 완충력이 발생되도록 하므로써, 범퍼의 완충력 향상에 일조할 수 있는 장점을 지니는 것이다.As described above, the present invention has a merit that it is possible to improve the buffering capacity of the bumper by allowing the buffering force to be generated by the explosion caused by the gas pressure using the nitrogen-filled capsule.
