The invention discloses an anti-falling unmanned aerial vehicle, which comprises a machine shell. A power chamber is arranged in the machine shell, a power mechanism is arranged in the power chamber, symmetrical supporting legs are hinged to the bottom end of the machine shell, the bottom end of each supporting leg is horizontally and rotationally connected with a winding shaft, walking wheels are fixed to the two ends of each winding shaft, and a buffering device is arranged at the bottom end of the machine shell. The buffering device comprises a buffering sleeve between the two supporting legs, a buffering rod, a buffering plate, a buffering shaft, a buffering fan, a buffering rack plate, a power shaft, a power gear, a transmission gear, a driven gear, a wire spool and a pull rope, wherein one end of the pull rope is connected with the bottom end of the buffering rack plate, and the other end of the pull rope is correspondingly wound on the wire spool. Through cooperation of the buffering device and a landing device, large resistance can be generated to reduce or counteract impact force generated during air crash, severe damage caused by hard landing of the unmanned aerial vehicle is avoided, a good protection effect is achieved, and the service life of the unmanned aerial vehicle is prolonged.

    本发明公开了一种防坠落无人机,包括机壳,机壳的内部设有动力室,动力室设有动力机构,机壳的底端铰接有对称的支撑腿,每个支撑腿的底端水平转动连接有收卷轴,每个收卷轴的两端固定有行走轮,机壳的底端设有缓冲装置,缓冲装置包括两个支撑腿之间的缓冲套筒、缓冲杆、缓冲板、缓冲轴、缓冲扇、缓冲齿条板、动力轴、动力齿轮、传动齿轮、从动齿轮、绕线盘以及一端与缓冲齿条板底端连接而另一端分别对应缠绕在绕线盘上的拉绳,发明通过缓冲装置和降落装置的配合下,可产生用于较大的抵抗力用于降低或抵消坠机时产生的冲击力,避免无人机硬着地而带来的严重的损坏,起到很好地防护作用,延长了其使用寿命。
