Abstract

운동에너지와 절삭에너지를 이용하여 차량의 충돌 또는 추돌 정도에 따라 충격흡수가 2단계로 구분되고 또는 연속적으로 이루어질 수 있게 하여 큰 충격에너지를 보다 효과적으로 흡수할 수 있도록 하는 절삭에너지를 갖는 차량용 범퍼를 제공하는 것이다.By using kinetic energy and cutting energy, shock absorption can be divided into two stages or continuously according to the collision or collision degree of the vehicle to provide a bumper for vehicles with cutting energy that can absorb large impact energy more effectively. It is.

본 발명은 직경이 다르게 2단으로 절삭봉과 절삭안내봉을 일체로 형성한 절삭에너지봉을 구성하여 상기 절삭봉을 범퍼의 배면에 고정 설치하고, 절삭안내봉은 범퍼임팩트 빔에 설치된 절삭커터에 자유단으로 삽입 설치하며, 상기 절삭에너지봉에 스프링을 개재하여 범퍼와 범퍼스테이 사이에 충격흡수를 1단계로 스프링이 흡수한 다음 충격정도에 따라 2단계에서 절삭커터가 절삭봉을 커팅하여 충격을 흡수할 수 있도록 한 것이다.The present invention constitutes a cutting energy rod formed by integrally forming the cutting rod and the cutting guide rod in two stages with different diameters, and the cutting rod is fixed to the rear surface of the bumper, and the cutting guide rod has a free end on the cutting cutter installed at the bumper impact beam. The spring is absorbed between the bumper and the bumper stay by the spring in the cutting energy rod in one step, and then the cutting cutter cuts the cutting rod in two steps according to the degree of impact to absorb the shock. I would have to.

Claims (1)

직경이 다르게 2단으로 절삭봉(10a)과 절삭안내봉(10b)을 일체로 형성한 절삭에너지봉(10)을 구성하여 상기 절삭봉(10a)을 범퍼(14)의 배면에 고정 설치하고, 절삭안내봉(10b)은 범퍼임팩트 빔(16)에 설치된 절삭커터(12)에 자유단으로 슬라이드 가능하게 삽입 설치하며, 상기 절삭에너지봉(10)에 스프링(18)을 개재하여 범퍼(14)와 범퍼스테이(16) 사이에 충격흡수를 1단계로 스프링(18)이 흡수 구분하고, 충격의 정도에 따라 2단계에서 절삭커터(12)가 절삭봉(10a)을 커팅하여 충격을 흡수할 수 있도록 한 것을 특징으로 하는 절삭에너지를 갖는 차량용 범퍼.The cutting rod 10a is fixed to the rear surface of the bumper 14 by constituting the cutting energy rod 10 having the cutting rod 10a and the cutting guide rod 10b integrally formed in two stages with different diameters. The cutting guide rod 10b is slidably inserted into the cutting cutter 12 installed on the bumper impact beam 16 at a free end, and the bumper 14 is interposed between the cutting energy rod 10 via a spring 18. Spring 18 is absorbed and separated in one step between the shock absorber and the bumper stay 16, and the cutting cutter 12 cuts the cutting rod 10a in two steps according to the degree of impact can absorb the shock. Bumper for a vehicle having a cutting energy, characterized in that. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
