The invention discloses a buffer undercarriage of an unmanned aerial vehicle. The buffer undercarriage comprises an unmanned aerial vehicle body, a bracket, bracket legs, a damping bracket and an advancing mechanism, the unmanned aerial vehicle body is fixedly connected with the top of the support, and the support legs are arranged at the bottom of the support. The damping support comprises a ratchet wheel support, a telescopic rod and a sleeve, the tail ends of the support legs are detachably connected with the ratchet wheel support, the ratchet wheel support is connected with the sleeve through a ratchet wheel mechanism, and the telescopic rod is slidably arranged in the sleeve in a sleeved mode; the advancing mechanism comprises a wheel carrier arranged at the bottom end of the telescopic rod and an advancing wheel hinged to the bottom of the wheel carrier. The support legs at the bottom of the unmanned aerial vehicle are detachably connected with the damping support, the connecting process is simple and easy to operate, the effect of being not prone to falling off can be achieved, and the damping effect of the unmanned aerial vehicle in the takeoff and landing process is improved; a ratchet mechanism is mounted on the damping bracket, so that the damping bracket can rotate outwards in the landing process of the unmanned aerial vehicle, the fuselage of the unmanned aerial vehicle can be protected, damage is avoided, and the service life of the unmanned aerial vehicle is prolonged.

    本发明公开了一种无人机的缓冲起落架,包括无人机机身、支架、支架腿、减震支架和行进机构;所述无人机机身与支架顶部固定连接,所述支架腿设置在支架的底部;所述减震支架包括棘轮支架、伸缩杆和套筒,所述支架腿末端与棘轮支架可拆卸连接,所述棘轮支架与套筒通过棘轮机构连接,所述伸缩杆滑动套设在套筒内;所述行进机构包括设置在伸缩杆的底端的轮架和铰接在轮架底部的行进轮。本发明无人机底部的支架腿与减震支架为可拆式连接,连接过程简单、易操作,可以达到不易脱落的效果,提高无人机起落过程中的减震效果;减震支架上装有棘轮机构,可以让无人机降落过程中使减震支架向外转动,可以保护无人机机身,避免损坏,提高无人机的使用寿命。
