阅读说明：本技术 安装机构、起落架、机架以及无人机 (Installation mechanism, undercarriage, frame and unmanned aerial vehicle ) 是由 刘彦辰 李玉 于 2018-03-14 设计创作，主要内容包括：一种安装机构,用于安装无人机的脚架,所述脚架设置在所述无人机的中心架的下方、且所述中心架的下方还设置有用于搭载有效载荷的载体,所述安装机构包括：旋转部以及驱动部；所述旋转部用于与所述中心架转动连接,且用于与所述脚架连接；所述驱动部用于在所述载体旋转时驱动所述旋转部旋转。通过设置安装机构来驱动脚架转动,可以避免影响载体的模态。本发明还提供一种无人机的起落架、机架以及无人机。(The utility model provides an installation mechanism for installation unmanned aerial vehicle's foot rest, the foot rest sets up the below of unmanned aerial vehicle's centre frame, just the below of centre frame still is provided with the carrier that is used for carrying on payload, installation mechanism includes: a rotating part and a driving part; the rotating part is used for being rotatably connected with the center frame and is used for being connected with the foot rest; the driving part is used for driving the rotating part to rotate when the carrier rotates. The mounting mechanism is arranged to drive the foot rest to rotate, so that the influence on the mode of the carrier can be avoided. The invention also provides an unmanned aerial vehicle undercarriage, a frame and an unmanned aerial vehicle.)
