The small unmanned aerial vehicle undercarriage comprises two supporting arms, a telescopic mechanism, a supporting mechanism and a buffering assembly, the two supporting arms are arranged below an unmanned aerial vehicle support side by side, one end of each supporting arm is connected with the unmanned aerial vehicle support in a pivoted mode, and a hinge lug is arranged on a supporting arm bottom beam close to the other end of each supporting arm; the telescopic mechanism is located above the two supporting arms, one end of the telescopic mechanism is connected with the unmanned aerial vehicle support in a pivoted mode, and the other end of the telescopic mechanism is connected with the hinge lugs on the two supporting arms in a pivoted mode through rotating shafts. The supporting mechanism is pivotally connected with the other ends of the two supporting arms; the buffering assembly is close to the supporting mechanism and fixedly arranged between the two supporting arms, and the buffering assembly is connected with the supporting mechanism. Therefore, the unmanned aerial vehicle not only has elastic force, but also has proper damping force, the bounce phenomenon during landing of the unmanned aerial vehicle can be effectively restrained, meanwhile, the undercarriage can be folded, air resistance is greatly reduced, and the flight stability of the unmanned aerial vehicle is effectively guaranteed.
本申请公开了一种小型无人机起落架,包括两个支撑臂、可伸缩机构、支撑机构和缓冲组件,其中,两个支撑臂并排设置在无人机支架的下方,且支撑臂的一端与无人机支架枢转相连,靠近支撑臂另一端的支撑臂底梁上设有铰耳;可伸缩机构位于两个支撑臂的上方,且可伸缩机构的一端与无人机支架枢转相连,可伸缩机构的另一端通过转轴与两个支撑臂上的铰耳枢转相连;支撑机构与两个支撑臂的另一端枢转相连;缓冲组件靠近支撑机构并固定设置在两个支撑臂之间,且缓冲组件与支撑机构相连。由此,不仅具备弹性力还拥有适当的阻尼力,能够有效地抑制无人机着陆时的弹跳现象,同时能够对起落架进行收起,大幅减少了空气阻力,有效保障了无人机飞行的稳定性。
