The invention discloses an amphibious undercarriage of a quad-rotor unmanned aerial vehicle. The amphibious undercarriage comprises an elastic component, the elastic component comprises an outer shell, an air storage tank, a communicating piece and an air bag, an inner cavity is formed in the outer shell, the air bag is arranged on the inner wall of the inner cavity, the inner cavity is communicated with the outside, the air storage tank is arranged on the outer shell, and the air storage tank is communicated with the air bag through the communicating piece; a second telescopic rod is pushed by gas pressure to push a push plate to move, so that a clamping block is separated from a clamping groove, a movable frame can drive a buffer frame to move upwards under the action of elastic force of a third spring, the situation that the buffer frame blocks the air bag which is gradually expanded and enlarged during inflation is avoided, and the situation that the buffer frame punctures the air bag which is gradually expanded and enlarged during inflation is avoided, when the air bag inflates, when the unmanned aerial vehicle lands from a high place, a better buffering protection effect can be achieved, and the unmanned aerial vehicle can float on the water surface and land on the water surface due to the buoyancy of the inflated air bag.

    本发明公开了一种四旋翼无人机水陆两用起落架,其包括弹性部件,弹性部件包括外壳体、储气罐、连通件和气囊,外壳体上设置有内腔,气囊设置在内腔内壁,内腔连通外界,外壳体上设置有储气罐,储气罐通过连通件连通气囊;第二伸缩杆在气体压力的推动下推动推板移动,使卡块脱离卡槽,活动框在第三弹簧弹力的作用下,能够带动缓冲架向上移动,避免缓冲架挡住充气时,逐渐膨胀变大的气囊,避免缓冲架戳破充气时逐渐膨胀变大的气囊,当气囊充气膨胀后,无人机从高处落地时,能够起到更好的缓冲保护作用,同时充气后的气囊具有的浮力,能够让无人机漂浮在水面上,在水面上也可以进行降落。
