The invention belongs to the technical field of automobile electric tail doors, and particularly relates to a one-way damper for an automobile electric tail door supporting rod, the one-way damper comprises a damper body, a driven shaft, a driving shaft and a first pressure providing piece, the driven shaft is connected with the damper body, and the driven shaft, the driving shaft and the first pressure providing piece are sequentially arranged in the telescopic direction of the tail door supporting rod; first ratchets and second ratchets are arranged on the opposite end faces of the driven shaft and the driving shaft correspondingly, and the first pressure providing piece is used for applying pressure to the driving shaft and the driven shaft, so that the second ratchets are meshed with the first ratchets; a lead screw of the tail door supporting rod is connected with the driving shaft, when the tail door supporting rod is shortened, the lead screw drives the driving shaft to rotate in the forward direction, the driving shaft sequentially drives the driven shaft and the damper body to rotate through mutual meshing of the first ratchet and the second ratchet, and when the tail door supporting rod is stretched, the lead screw drives the driving shaft to rotate in the reverse direction. And the driving shaft slides relative to the driven shaft through the matching of the first ratchet and the second ratchet.
本发明属于汽车电动尾门技术领域，尤其涉及一种汽车电动尾门撑杆用单向阻尼器，包括阻尼器本体、从动轴、主动轴和第一压力提供件，从动轴与阻尼器本体连接，从动轴、主动轴和第一压力提供件沿尾门撑杆的伸缩方向依次设置，从动轴和主动轴相对的端面上分别设置有第一棘齿和第二棘齿，第一压力提供件用于向主动轴和从动轴施加压力，使第二棘齿和第一棘齿相互啮合；尾门撑杆的丝杆与主动轴连接，当尾门撑杆缩短时，丝杆带动主动轴正向旋转，且主动轴通过第一棘齿和第二棘齿相互啮合依次驱动从动轴和阻尼器本体旋转，当尾门撑杆伸长时，丝杆带动主动轴反向旋转，且主动轴通过第一棘齿和第二棘齿配合相对于从动轴打滑。
