Disclosed is a movable unmanned aerial vehicle undercarriage with a buffering function comprises a mounting plate fixed to the bottom of an unmanned aerial vehicle, first lug seats are fixedly connected to the four corners of the outer wall of the bottom of the mounting plate correspondingly, and movable rods are rotationally connected to the inner walls of the first lug seats through pin shafts; and one end of each movable rod is rotationally connected with a second lug seat through a pin shaft, the outer wall of the bottom of the second lug seat is fixedly connected with a telescopic rod, the outer wall of the telescopic rod is sleeved with a sleeve, and the outer wall of the bottom of the sleeve is fixedly connected with a lifting plate. When an unmanned aerial vehicle lands, generated impact force can promote a movable rod to rotate on a first lug seat and stretch a first spring to achieve a certain buffering effect, at the moment, a landing plate can slide towards the two sides, and in the sliding process, a sliding block at one end of a sliding rod can slide in a fixed cylinder, so that the overall stability of the landing gear is guaranteed; and meanwhile, a third spring in a fixing cylinder can be stretched by a sliding block, the buffering effect is further achieved, and the using effect is better.

    本发明公开了一种可移动式具有缓冲功能的无人机起落架,包括固定于无人机底部的安装板,所述安装板底部外壁的四个拐角处均固定连接有第一耳座,且第一耳座的内壁通过销轴转动连接有活动杆,所述活动杆的一端通过销轴转动连接有第二耳座,且第二耳座的底部外壁固定连接有伸缩杆,所述伸缩杆的外壁套接有套筒,且套筒的底部外壁固定连接有起落板。本发明中当无人机降落时,产生的冲击力会促使活动杆在第一耳座上转动,并拉伸第一弹簧起到一定的缓冲作用,此时起落板会向两侧滑移,滑移过程中,滑杆一端的滑块会在固定筒内滑动,保证起落架的整体稳定性,同时滑块会拉伸固定筒内的第三弹簧,进一步起到缓冲作用,使用效果更佳。
