The invention discloses a shock-absorbing unmanned aerial vehicle undercarriage, and relates to the field of unmanned aerial vehicles The shock-absorbing unmanned aerial vehicle undercarriage comprises a shock-absorbing mounting frame fixed to the bottom of an unmanned aerial vehicle body, and a first-stage shock-absorbing assembly is arranged at the bottom of the shock-absorbing mounting frame and comprises swing rods which are in bilateral symmetry and rotationally connected with the shock-absorbing mounting frame; a first damping piece is fixedly connected between the outer side of the swing rod and the damping mounting frame. The end, away from the unmanned aerial vehicle body, of the swing rod is rotationally connected with a second-stage swing rod, and the second-stage swing rod is rotationally connected with the swing rod in a damping mode. In the landing process, a swing rod of the first-stage damping assembly and a second-stage swing rod swing outwards, in the process, a first damping piece absorbs impact caused by vibration, and the impact can also be absorbed through damping rotating connection between the second-stage swing rod and the swing rod; the guide rod can synchronously stretch the second damping piece, and the second damping piece conducts damping and energy absorption. In addition, the rack drives the second-stage damping assembly to work, the sliding plate and the sleeve slide in a damping mode, and the inflatable air bag is inflated, so the effect of absorbing vibration can be achieved.

    本发明公开了一种避震的无人机起落架,涉及无人机领域,包括固定于无人机机体底部的减震安装架,所述减震安装架底部设置有一级减震组件,一级减震组件包括左右对称与减震安装架转动连接的摆动杆,摆动杆外侧与减震安装架之间固定连接有第一减震件;所述摆动杆远离无人机机体的一端转动连接有二级摆杆,二级摆杆与摆动杆阻尼转动连接。降落时,一级减震组件的摆动杆与二级摆杆向外摆动,过程中第一减震件吸收震动带来的冲击,通过二级摆杆与摆动杆之间阻尼转动连接,也能吸收冲击;导向杆会同步拉伸第二减震件,第二减震件则进行减震吸能,此外齿条带动二级减震组件工作,滑板与套管阻尼滑动,并且充气气囊充气,均能起到吸收震动的作用。
