The invention discloses an undercarriage of a rotor unmanned aerial vehicle, and relates to the technical field of unmanned aerial vehicles. The undercarriage of the rotor unmanned aerial vehicle comprises a vehicle body, buffer mechanisms used for buffering four landing plates are arranged on the vehicle body, speed limiting mechanisms used for limiting the resilience force of buffer springs are arranged in two buffer pipes, and each speed limiting mechanism comprises a plurality of speed limiting arc plates slidably connected into the corresponding buffer pipe. The side, close to the buffer plate, of each speed limiting arc plate is provided with a first inclined face. According to the undercarriage of the unmanned rotorcraft, by arranging the speed limiting mechanism, the reverse moving speed of the buffer plate is limited, the repeated elastic change of the buffer spring in the process of buffering the unmanned rotorcraft body is reduced, meanwhile, by arranging a plurality of air inlet mechanisms and an air outlet mechanism, the reverse elastic force of the buffer spring is subjected to damping speed limiting, and therefore the buffering effect of the unmanned rotorcraft body is improved. And the landing stability of the aircraft body is improved.

    本发明公开了一种旋翼无人机的起落架,涉及无人机技术领域。该种旋翼无人机的起落架,包括机体,所述机体上设有用于对四个起落板进行缓冲的缓冲机构,两个所述缓冲管内设有用于对缓冲弹簧的回弹力进行限速的限速机构,所述限速机构包括滑动连接在缓冲管内的多个限速弧板,各个所述限速弧板靠近缓冲板的一侧开设有第一斜面。该种旋翼无人机的起落架,通过限速机构的设置,对缓冲板的反向移动速度进行了限速,降低了缓冲弹簧在对机体进行缓冲过程中的反复弹性变化,同时通过多个进气机构和一个出气机构的设置,对缓冲弹簧的反向弹性力进行了阻尼限速,提高了机体降落时的稳定性。
