The invention relates to a foot stool assembly and an unmanned aerial vehicle, the foot stool assembly comprises a body and a damper connected to the body, the damper is provided with a deformation cavity, an auxiliary cavity and a first throttling opening, the deformation cavity communicates with the auxiliary cavity through the first throttling opening, and the deformation cavity and the auxiliary cavity are filled with damping liquid; damping liquid can circulate between the deformation cavity and the auxiliary cavity through the first throttling opening. When the unmanned aerial vehicle lands, the body extrudes the damper downwards, the damper deforms to reduce the volume of the deformation cavity, the damping liquid in the deformation cavity is pressed into the auxiliary cavity through the first throttling opening, and a large amount of heat is generated by friction and impact between the damping liquid and the first throttling opening and released into the air. Therefore, most of the impact on the unmanned aerial vehicle during landing is converted into heat for dissipation, and the impact on the unmanned aerial vehicle body during landing of the unmanned aerial vehicle is weakened. Meanwhile, due to the fact that the damper is light in overall mass, the flight burden of the unmanned aerial vehicle is relieved, and the damper does not comprise a transmission or movable structure and is high in reliability.

    本申请涉及一种脚架组件及无人机,脚架组件包括:本体和连接于本体的阻尼器,阻尼器设置有变形腔、辅助腔和第一节流口,变形腔和辅助腔通过第一节流口连通,变形腔和辅助腔内填充阻尼液,阻尼液能够通过第一节流口在变形腔和辅助腔之间流通。当无人机降落时,本体向下挤压阻尼器,阻尼器发生变形导致变形腔的容积减小,变形腔中的阻尼液通过第一节流口被压入辅助腔中,阻尼液与第一节流口之间的摩擦和冲击等产生大量的热并释放到空气中,从而将无人机降落时受到的冲击大部分转化为热量的形式耗散,减弱无人机降落时对无人机机体的冲击。同时,由于阻尼器的整体质量较轻,减轻了无人机的飞行负担,且阻尼器不包含传动或活动结构,可靠性较高。
