The aircraft buffer undercarriage comprises an unmanned aerial vehicle, two supporting frames are symmetrically and rotatably connected to the bottom of the unmanned aerial vehicle through a rotating shaft, an air bag is fixed between the two supporting frames, the top of the unmanned aerial vehicle is covered with a parachute, driving mechanisms are arranged on the two sides of a gas filling assembly, and under the action of a limiting frame, the air bag is inflated into the air bag through the driving mechanisms. Compared with the prior art, when the supporting frame is unfolded through the driving mechanism, the gas filling assembly fills inert gas into the gas bag, so that the gas bag is expanded to form a buffering gas bag at the bottom of the unmanned aerial vehicle, the contact area is increased, a parachute at the top of the unmanned aerial vehicle is unfolded, and the unmanned aerial vehicle is more stable. The landing speed is reduced through air flow, synchronous inflation, supporting frame unfolding and parachute opening are achieved, and the influence of landing impact force on the unmanned aerial vehicle and the supporting frame is reduced to the maximum degree through cooperation with the air bag.

    本发明提供一种飞行器缓冲起落架,包括无人机,所述无人机底部通过转轴对称转动连接有两个支撑架,两个所述支撑架之间固定有气囊袋,所述无人机顶部覆盖有降落伞,且气体充入组件两侧设有驱动机构,通过限位框的作用下,第二齿板的移动路径通过限位框限位,保持竖直方向,相对于现有技术,通过驱动机构将支撑架展开时,气体充入组件向气囊袋充入惰性气体,使之膨胀形成无人机底部的缓冲气囊,增大接触面积,无人机顶部的降落伞展开,通过气流降低落地时的速度,实现充气、支撑架展开和降落伞打开同步进行,与气囊配合最大化的降低落地的冲击力对无人机本身和支撑架的影响。
