The invention discloses a shockproof undercarriage of an unmanned aerial vehicle, which utilizes an expanding cylinder barrel, a reducing cylinder barrel and a piston capable of being quickly combined and disassembled in the shockproof undercarriage of the unmanned aerial vehicle, so that the shockproof effect of the shockproof undercarriage is improved while the use stability and proper size of the shockproof undercarriage of the unmanned aerial vehicle are ensured. The undercarriage comprises a mounting plate and a plurality of telescopic rods connected to the mounting plate, and a supporting bottom plate is arranged at the end, away from the mounting plate, of each telescopic rod; each telescopic rod comprises a cylinder barrel, a piston assembly and a piston rod, an inner cavity of the cylinder barrel comprises a reducing cavity and an expanding cavity which are coaxially arranged and communicated with each other, the piston assembly comprises a first piston and a second piston, and the first piston is slidably arranged in the reducing cavity and can slide towards the expanding cavity; one end of the piston rod slidably penetrates into the reducing cavity and is connected with the first piston, and the other end of the piston rod is connected with the supporting bottom plate. The undercarriage has the advantages of good damping effect, stable operation of the whole structure, neat appearance and the like.

    本发明公开了无人机防震起落架,利用无人机防震起落架中的扩径缸筒、缩径缸筒以及可快速合并和拆卸的活塞,在保证无人机起落架使用稳定、尺寸大小适宜的同时,提高防震起落架的防震效果。本发明包括安装板以及连接在安装板上的多个伸缩杆,每个伸缩杆远离安装板的一端均设置有支撑底板;伸缩杆包括缸筒、活塞组件和活塞杆,缸筒的内腔包括同轴设置且相互连通的缩径腔和扩径腔,活塞组件包括第一活塞和第二活塞,第一活塞可滑动地设置于缩径腔内并可朝扩径腔滑动,活塞杆一端可滑动地穿入至缩径腔内并与第一活塞连接,活塞杆另一端与支撑底板连接。本发明具减震效果好,整体结构运行稳定,外观整洁等优点。
