The invention discloses a damping undercarriage of an unmanned rotorcraft, and belongs to the field of unmanned aerial vehicles. The damping undercarriage comprises a fixing plate, a bottom frame and a plurality of supporting rods connected between the fixing plate and the bottom frame, the two ends of each supporting rod are hinged to a fixing block and a sliding block respectively, the fixing block is fixedly connected to the fixing plate, and the sliding block is slidably connected to the bottom frame; the bottom frame comprises a frame body and damping assemblies arranged on the frame body, and each sliding block is provided with a corresponding damping assembly; and each damping assembly comprises a piston barrel, a piston, a piston rod, a spring and a spring baffle, the piston barrel is fixedly installed on the frame body, the piston is located in the piston barrel, one end of the piston rod is fixedly connected to the piston, the other end of the piston rod extends out of the piston barrel and then is fixedly connected with the sliding block, the spring baffle sleeves the side wall of the piston rod located on the outer side of the piston barrel, the spring baffle is fixed to the frame body, and the spring sleeves the side wall of the piston rod between the spring baffle and the sliding block. The damping undercarriage has a good damping effect and can effectively reduce impact when the unmanned aerial vehicle lands.
