Abstract

본 발명은 차량의 도어 개폐용 스테이 댐퍼의 사이즈를 최소화시켜 좁은 공간에 설치가 가능하고, 작동시간을 단축하며, 도어 단계적 개폐가 가능하도록 한 차량의 도어 개폐용 다단식 스테이 댐퍼에 관한 것으로 종래의 스테이 댐퍼(3)는 도어(2)의 개폐정도를 실린더(4)와 로드의 길이로 조절하여야 하므로 도어(2)의 개폐 정도를 크게하기 위하여 스테이 댐퍼(3)의 길이가 길어져야만 하고, 따라서 상기 스테이 댐퍼(3)의 소형화가 용이하지 못하여 스테이 댐퍼(3)가 많은 공간을 차지할 뿐 아니라, 좁은 공간에 설치할 수 없는 문제점이 있었던바, 내부에 통공(12)이 형성된 피스톤(11)을 설치한 1차 실린더(10)와; 후단을 상기 1차 실린더(10)의 내부 피스톤(11)과 결합시키되, 상기 1차 로드 겸용 2차 실린더(20)의 내부에 통공(22)이 형성된 피스톤(21)을 설치한 1차로드 겸용 2차 실린더(2)와; 상기 1차 로드 겸용 2차 실린더(20)의 피스톤(21)에 후단을 결합한 2차 로드(30)로 형성하여 스테이 댐퍼의 크기를 최소화하여 좁은 공간에 설치할 수 있어 공간 효율에 유리할 뿐 아니라, 다단식으로 동시에 작동하므로 도어의 개폐 속도가 신속하며, 도어의 부분 개폐 및 단계별 개폐가 가능한 것임.The present invention relates to a multi-stage stay damper for door opening and closing of a vehicle that can be installed in a narrow space by minimizing the size of the door damper for door opening and closing, to reduce the operation time, and to open and close the door step by step. Since the damper 3 should adjust the opening and closing degree of the door 2 to the length of the cylinder 4 and the rod, the length of the stay damper 3 should be long to increase the opening and closing degree of the door 2, and thus Since the stay damper 3 was not easily downsized, the stay damper 3 occupied a lot of space, and there was a problem that it could not be installed in a narrow space. The piston 11 having a through hole 12 formed therein was installed. A primary cylinder 10; Combine the rear end with the inner piston 11 of the primary cylinder 10, the primary rod combined with a piston 21 having a through-hole 22 formed in the primary rod secondary cylinder 20 A secondary cylinder 2; The secondary rod 30 coupled to the rear end of the piston 21 of the primary rod combined secondary cylinder 20 can be installed in a narrow space by minimizing the size of the stay damper. As it operates at the same time, the opening and closing speed of the door is quick, and partial opening and closing of the door is possible.
