Abstract

본 발명은 자동차의 엔진후드(Hood)나 트렁크의 개폐를 용이하도록 하기 위해 사용된 가스 스프링에 관한 것으로, 종래의 가스 스프링에서는 쿠페타입과 같은 트렁크의 열림각도가 낮은 차량에 웨곤과 같은 트렁크 열림 각도가 큰 차량의 가스스프링을 그대로 사용할 경우, 피스톤 로드 최대신장시에 피스톤이 오일에 완전히 잠기지 않게 되므로, 윤활작용이 제대로 이루어지지 않아 개문동작시 충격이 발생되는 문제점이 있었으나, 본 발명에서는 저장튜브 내측의 피스톤로드상에 신축성 재질의 범퍼를 결함하여, 피스톤포드 최대신상시 피스톤과 저장튜브 상면 사이에 충격을 흡수토록하여 항상 부드러운 개문동작이 이루어지도록 하였다.The present invention relates to a gas spring used to facilitate opening and closing of an engine hood or trunk of an automobile. In the conventional gas spring, a trunk opening angle of a trunk such as a wagon is applied to a vehicle having a low opening angle of a trunk such as a coupe type. When the gas spring of a large vehicle is used as it is, the piston is not completely immersed in the oil when the piston rod is fully extended, so that the lubrication is not performed properly, and there is a problem that an impact occurs when the opening operation is performed. The bumper made of a flexible material on the piston rod of the cylinder was defective, so that the shock absorbed between the piston and the upper surface of the storage tube at the maximum extension of the piston pod so that the smooth opening operation was always performed.
