Abstract

본 발명은 내파이프의 끝단의 외파이프에 2개를 1조로한 흡수돌기를 내향돌설시켜 내, 외파이프의 좌굴시 흡수 돌기에 의해 충격에너지를 흡수할 수 있도록한 자동차용 스티어링 컬럼의 충격에너지 흡수구조에 관한 것이다.The present invention absorbs the impact energy of the steering column for automobiles by inwardly protruding the two absorption protrusions into the outer pipe at the end of the inner pipe and absorbing the impact energy by the absorption protrusion during the buckling of the outer pipe. It's about structure.

본고안은 스티어링 컬럼을 내, 외파이프를 결합하여 형성하되, 내파이프 끝단 위치의 외파이프 90° 선상에 흡수 돌기를 2곳에 내향돌설시켜 내, 외파이프의 좌굴시 압입고정된 압입력을 벗어나면서 충격에너지를 흡수하다 내파이프의 끝단이 흡수돌기에 좁촉되는 순간부터 재차 충격에너지 흡수토록하여 운전자의 안전을 도모할 수 있도록한 것이 그 특징이다.In this proposal, the steering column is formed by combining the outer pipe, but the absorbing protrusions are projected in two places on the outer pipe 90 ° line at the end of the inner pipe, and out of the press-fit fixed pressure input when the outer pipe is buckled. Absorbs shock energy It is characteristic that the driver's safety can be promoted by absorbing shock energy again from the moment when the end of the inner pipe is narrowed to the absorption protrusion.
