본 고안은 자동차용 범퍼로서 충돌사고시 발생되는 충격을 완화 시키도록 한 것에 관한 것이다.The present invention relates to a bumper for automobiles to mitigate the impact generated during a crash.

종래에는 충돌사고시 발생되는 충격을 완화시키기 위한 제안이 많이 있었으나, 대개가 충격을 시린더와 피스톤 또는 스프링에 의하여 충격을 완화시키도록 구성들로써 이들은 충격에 대한 완화가 완만치 못하였다.In the past, there have been many proposals for mitigating impacts generated during a crash, but they are not mitigated.

본 고안은 이러한 점을 감안하여 고안한 것으로써 범퍼의 전면을 스프링과 공기주입식 피스톤을 이용함으로써 충돌시에 발생되는 충격을 완화하여 충돌로 인한 사고시에 인명에 피해를 주는 것을 방지할 수 있도록 한 것이다.The present invention has been devised in view of this point, and by using a spring and an air-injection piston at the front of the bumper, the impact generated during a collision can be alleviated to prevent damage to human life in the event of a collision. .

이와 같은 본 고안의 구성을 첨부 도면에 의하여 설명하면 다음과 같다. 정면범퍼(1)내에 형성된 원통(2)내에 원통(5)이 삽입되어 스프링(6)으로 탄지된 것에 있어서 원통(2)내에 돌봉(3)을 형성하고, 원통(5)내에 형성되고 통공(7)이 뚫린 시린더(7)내에 돌봉(3)의 선단에 형성된 피스톤(8)이 삽입되게 하되 시린더(7)의 선단부(9)와 피스톤(8) 사이에는 고무링(10)을 삽설하여서 된 것이다.Referring to the configuration of the present invention as described in the accompanying drawings as follows. The cylinder 5 is inserted into the cylinder 2 formed in the front bumper 1 to form a stone bar 3 in the cylinder 2 in which the cylinder 6 is supported by a spring 6, and is formed in the cylinder 5 to form a through hole ( The piston (8) formed at the tip of the stone bar (3) is inserted into the cylinder (7) where the hole (7) is drilled, but the rubber ring (10) is inserted between the tip (9) of the cylinder (7) and the piston (8). It was done.

미설명 부호(17) (11')는 정면범퍼(1)와 배면판(4)의 사이 상, 하에 형성된 주름판이다.Reference numerals 17 and 11 ′ are corrugated plates formed above and below the front bumper 1 and the back plate 4.

이와 같은 본 고안의 효과를 설명하면 다음과 같다.When explaining the effect of the present invention as follows.

충돌에 의하여 정면범퍼(1)에 충격이 가해지면 스프링(6)으로 받쳐있던 원통(2)이 안쪽으로 밀려드러감과 동시에 돌봉(3)에 형성된 피스톤(8)이 밀려들어가게 되어 시린더(7)내의 공기는 통공(7')를 통하여 배출된다. 이때 피스톤(8)이 밀려들어가게 되면 처음에는 시린더(7)에 뚫린 통공(7')이 많기 때문에 공기의 배출 많고, 갈수록 통공(7')이 적어지기 때문에 피스톤(8)이 들어가는 속도가 줄어들어 완충작용을 원활하게 할 수 있는 것이다.When the impact is applied to the front bumper 1 by the collision, the cylinder 2 supported by the spring 6 is pushed inward, and the piston 8 formed on the stone bar 3 is pushed in to the cylinder 7. The air inside is discharged through the through hole 7 '. At this time, when the piston (8) is pushed in, at first, there are a lot of through holes (7 ') drilled in the cylinder (7), the air is discharged a lot, and the through holes (7') is gradually reduced, so the speed at which the piston (8) enters decreases It will be able to smoothly buffer.

그리고 정면범퍼(1)가 밀려들어가게 되면 정면범퍼(1)와 배면판(4)의 상, 하 사이에 형성된 주름판(11) (11')이 주름이 지게 되므로 외형에 대한 파손을 방지할 수 있는 것이다.When the front bumper 1 is pushed in, the wrinkled plates 11 and 11 ′ formed between the top and bottom of the front bumper 1 and the rear plate 4 are wrinkled, thereby preventing damage to the appearance. It is.

그리고 충격을 받아밀려 들어갔던 정면범펴(1)가 원위치로 환원될 때는 스프링(6)에 의하여 정면범퍼(1)가 원위치되는데 이때는 공기가 통공(7')을 통하여 시린더(7)내로 유입되어 피스톤(8)이밀려나가게 되어 원위치되는 것이다. 그리고 원위치로 될 때 피스톤(8)이 원위치하면서 선단부(9)에 충격을 가하여 파손되는 것을 방지하기 위하여 피스톤(8)과 선단부(9)내에는 고무링(10)을 삽입한 것이다. 이와 같은 본 고안은 충돌시의 충격을 최대로 완화시킬 수 있고, 또한 충격에 의하여 외형이 파손되는 것을 방지할 수 있는 실용적인 고안이다.When the front bumper 1, which was pushed in by the shock, is returned to its original position, the front bumper 1 is returned to its original position by a spring 6, in which air is introduced into the cylinder 7 through the through hole 7 '. The piston (8) is pushed out of the original position. And the rubber ring 10 is inserted into the piston (8) and the front end (9) in order to prevent the piston (8) from being in the original position and to be damaged by impacting the front end (9). The present invention as described above is a practical design that can alleviate the impact at the time of the collision to the maximum, and also prevent the appearance from being damaged by the impact.
