The invention relates to a height adjustable seatpost for a bicycle. An exemplary height adjustable seatpost includes an upper tube and a lower tube configured in a telescopic arrangement. The height adjustable seating post includes a piston in the upper tube that divides the upper tube into a first chamber and a second chamber. The piston defines a fluid passage between the first chamber and the second chamber. The height adjustable seating post also includes a plug located in the fluid passage. The plug is movable in a linear direction between an open position allowing fluid flow through the fluid passage and a closed position preventing fluid flow through the fluid passage. The height adjustable seating post also includes a motor and a cam assembly for converting rotational motion of the motor into linear motion of the plug.
本发明涉及用于自行车的高度可调节座杆。示例性高度可调节座杆包括以伸缩布置方式配置的上管和下管。高度可调节座杆包括位于上管中的活塞,该活塞将上管分成第一腔室和第二腔室。活塞限定位于第一腔室和第二腔室之间的流体通路。高度可调节座杆还包括位于流体通路中的塞。塞可在线性方向上在允许流体流过流体通路的打开位置和阻止流体流过流体通路的关闭位置之间移动。高度可调节座杆还包括马达和凸轮组件,该凸轮组件用于将马达的旋转运动转换为塞的线性运动。
