The invention discloses a vibration reduction type undercarriage of an unmanned aerial vehicle. The vibration reduction type undercarriage comprises a hydraulic damper installed on the unmanned aerialvehicle, a wheel carrier hinged to a piston rod of the hydraulic damper and movably connected with an aircraft wheel, and a tension spring with the two ends connected with a cylinder body of the hydraulic damper and the wheel carrier correspondingly. Impact borne by all parts of the unmanned aerial vehicle can be greatly damped through the damping structures of the three parts so as to guaranteesafe rising and falling of the unmanned aerial vehicle, the two ends of the tension spring are arranged on the plug pins in a sleeving mode, and therefore the tension spring, the hydraulic damper andthe wheel carrier can be rapidly connected together. During disassembly, the tension spring can be quickly disassembled only by separating the end of the tension spring from a bolt, so that the disassembly and the replacement are convenient and quick. In addition, the bearing range of the undercarriage can be adjusted by replacing different tension springs and hydraulic dampers according to the total weight of the unmanned aerial vehicle, matched bearing is made to be within the permitted range, use is flexible, and the range is wide.
本发明公开了一种无人机的减振式起落架,包括安装于无人机上的液压阻尼器,与液压阻尼器的活塞杆铰接且与机轮活动连接的轮架,以及两端分别与液压阻尼器的缸体和轮架连接的拉簧。本发明通过三部分的衰减结构可以使无人机的各部分零部件受到的冲击极大地被衰减,以保证无人机的安全起落,并且拉簧的两端套设于插销上,从而可以快速地将拉簧与液压阻尼器和轮架连接在一起。在拆卸时,只需将拉簧的该端脱出插销即可快速地将拉簧拆卸下来,拆卸和更换方便、快捷。本发明还可以根据无人机的总体重量,通过更换不同的拉簧和液压阻尼器,可以调节起落架承重的范围,使搭配承重在许可范围内,使用灵活和范围广。
