The invention discloses an unmanned aerial vehicle with buffer undercarriages. The unmanned aerial vehicle comprises a fuselage; vehicle arms which are connected with the fuselage; rotor wing assemblies which are arranged at the ends, away from the fuselage, of the vehicle arms; a undercarriage which is arranged below the fuselage, and the undercarriage comprises a horizontal first pipe fitting located at the uppermost part; a connecting sleeve which is elastic, the connecting sleeve is constructed to be of an open-loop structure, an opening of the connecting sleeve faces downwards, the connecting sleeve is arranged on the first pipe fitting in a sleeving mode through the opening and can move in the axial direction of the first pipe fitting, a fastener is arranged at the opening of the connecting sleeve, and the fastener is used for fixing the connecting sleeve; and a frame plate which is located above the connecting sleeve and rotationally connected with the connecting sleeve, the frame plate is constructed to be suitable for being detachably connected with the machine body, and a vertical spring is arranged between the frame plate and the connecting sleeve. When the unmanned aerial vehicle lands, the frame plate can rotate relative to the connecting sleeve, so that impact on the vehicle body can be reduced, and meanwhile, the springs can be used for buffering overturning moment generated during landing to prevent the unmanned aerial vehicle from rolling over.

    本发明公开了一种具有缓冲起落架的无人机,包括:机身;机臂,机臂与机身相连;旋翼组件,旋翼组件设于机臂的远离机身的一端;起落架,起落架设于机身的下方,起落架包括位于最上方的水平的第一管件;连接套,连接套具有弹性,连接套被构造成开环状结构,且其开口朝向下方,连接套通过开口外套在第一管件上且可沿第一管件轴向移动,连接套的开口处设有紧固件,紧固件用于固定连接套;和架板,架板位于连接套的上方且与连接套转动连接,架板被构造成适于与机身可拆卸相连,架板与连接套之间设有竖向的弹簧。在无人机降落时,架板可相对连接套转动,从而可减轻机身所受到的冲击,同时弹簧可用来缓冲降落时产生的倾覆力矩,防止无人机侧翻。
