The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle undercarriage with a buffer mechanism, which comprises an upper support arm and a lower support arm, the device further comprises a movable supporting arm, a vibration absorption assembly, a clamping assembly and a transmission assembly. The movable support arm is rotationally connected to the lower support arm; the vibration absorption assembly is installed in the upper supporting arm. The clamping assembly is connected to the lower supporting arm in a sliding mode. The transmission assembly is mounted on the clamping assembly; the vibration absorption assembly divides the upper supporting arm into an air cavity and an oil cavity, the upper supporting arm extrudes the lower supporting arm, the lower supporting arm drives the air cavity and the oil cavity of the vibration absorption assembly to compress and absorb impact, the upper supporting arm drives the clamping assembly to rotate and drives the transmission assembly to rotate, the transmission assembly rotates to open the movable supporting arm, and vibration of the plant protection unmanned aerial vehicle during forced landing is reduced; the stability of plant protection plants in forced landing is improved, and the risk that the plant protection unmanned aerial vehicle is overturned due to shaking of liquid medicine in the box body is reduced.

    本发明涉及无人机技术领域,具体涉及一种具有缓冲机构的无人机起落架,包括上支臂、下支臂;还包括活动支臂、吸振组件、卡接组件、传动组件;所述活动支臂转动连接在下支臂上;所述吸振组件安装在上支臂中;所述卡接组件滑动连接在下支臂上;所述传动组件安装在卡接组件上;吸振组件将上支臂分为气腔和油腔,上支臂挤压下支臂,下支臂驱动吸振组件的气腔和油腔压缩吸收冲击,上支臂驱动卡接组件转动并带动传动组件转动,传动组件旋转打开活动支臂,减小了植保无人机迫降时的振动,提高了植保植物人迫降时的稳定性,降低了植保无人机因箱体内药液晃动而导致倾翻的风险。
