Abstract

본 발명은 자동차에 사용되는 충격완화 범퍼에 관한 것으로, 특히 범퍼를 개량하여 그내부에 충격을 흡수하느 쇽업쇼바를 적소에 내장함으로써 차량출돌 등에 의한 충격을 흡수할 수 있도록 한 자동차의 충격완화 범퍼에 관한 발명이다. 본 발명은 차체(4)의 선후단에 부착되는 강철프레임(3) 씌워지는 FRP범퍼(1)와, 상기 강철프레임(3)과 FRP범퍼(1)사이에 발포성 우레탄폼(6)을 개재시켜서 이루어진 자동차의 범퍼에 있어서; 쇽업쇼파(23)와, 쇽업쇼바(23)의 양끝에 일체로 부착된 전후면캡(21,22)사이에 지지되며 상기 쇽업쇼바(23)의 외주에 삽설되는 스프링(24)으로 이루어지는 완충기(2)가 상기 강철프레임(3)과 FRP범퍼(1)의 내면에 장설되는 플레이트(25)에 부착되어 구성된 것으로, 높은 충격에 대해서도 효과적으로 완충을 할 수 있으며, 추가 구성되는 부품들도 간편하여 경제성이 있으며, 견고한 구조를 가지므로 내구성도 가질 뿐만 아니라, 충돌후에도 교체가 필요없어서 반영구적으로 사용할 수 있으며, 거의 모든 차량에 적용되는 우수한 발명인 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock alleviation bumper used in automobiles, and more particularly, to a shock alleviation bumper for automobiles that is capable of absorbing shock caused by a vehicle crash by incorporating a shock absorber in place to absorb the impact therein. Invention. The present invention is interposed between the FRP bumper (1) is covered with a steel frame (3) attached to the front and rear ends of the vehicle body 4, and the foamed urethane foam (6) between the steel frame (3) and the FRP bumper (1) In the bumper of a motor vehicle; A shock absorber (2) comprising a spring (23) and a spring (24) supported between the front and rear caps (21, 22) integrally attached to both ends of the shock absorber (23) and inserted into the outer periphery of the shock absorber (23). ) Is attached to the plate 25 installed on the inner surface of the steel frame (3) and the FRP bumper (1), can be effectively buffered against high impact, and the additional components are simple and economical In addition, since it has a solid structure, it not only has durability, but also does not need replacement after a collision, and thus can be used semi-permanently, and is an excellent invention applied to almost all vehicles.
