The invention discloses a multi-rotor unmanned aerial vehicle with a damping undercarriage structure and belongs to the field of unmanned aerial vehicles. The multi-rotor unmanned aerial vehicle comprises a fuselage, arms and a lift assembly, wherein a damping undercarriage is mounted on a bottom surface of the fuselage, and the multi-rotor unmanned aerial vehicle comprises a connecting seat, a supporting rod, a connecting ring, a damping spring and a supporting spring; at least two connecting seats are fixedly mounted on the same circumference of a bottom surface of the machine body, and pin shafts which are horizontally arranged are fixedly mounted on the connecting seats; pin holes matched with the pin shafts are formed in the upper ends of the supporting rods, and the number of the supporting rods is the same as that of the connecting bases so that the supporting rods can be hinged to the connecting bases; the connecting ring is arranged below the center of the bottom face of the machine body, connecting hanging points are arranged on the upper portion and the lower portion of the supporting rod, and damping springs are connected between the connecting hanging points and the connecting ring; supporting springs are connected between the supporting rods and the bottom face of the machine body; elastic force provided by the damping springs and the supporting springs enables the supporting rods to be kept in an inclined state. According to the unmanned aerial vehicle, impact force during landing can be effectively buffered so as to protect recording equipment.

    本发明公开一种具有减震起落架结构的多旋翼无人机,属于无人机领域,包括机身、机臂和升力组件,机身的底面安装有减震起落架,包括连接座、支撑杆、连接环、减震弹簧和支持弹簧;连接座至少有两个且固定安装以机身底面的同一圆周上,连接座上固定安装有呈水平状布置的销轴;支撑杆的上端设置有与销轴相适配的销孔,支撑杆与连接座的数量相同以使每个连接座上均铰接有支撑杆;连接环设置在机身的底面中心的下方,支撑杆的上部和下部均设置有连接挂点,连接挂点与连接环之间均连接有减震弹簧;支撑杆与机身的底面之间均连接有支持弹簧;减震弹簧和支持弹簧提供的弹力使支撑杆保持倾斜状态。本发明能有效缓冲降落时的冲击力以保护记载设备。
