The invention provides a propeller assembly and an unmanned aerial vehicle, and relates to the technical field of unmanned aerial vehicles. The propeller assembly comprises blades, a mounting body, alimiting piece and a movable piece. The blades are rotatably connected to the mounting body and can rotate to an unfolded state relative to the mounting body. The limiting pieces are fixed to the blades, and the movable pieces are movably arranged on the mounting body. And under the condition that the blades are in an unfolded state, the limiting pieces are clamped with the movable pieces so thatthe limiting pieces can be fixed relative to the mounting body. And the movable piece can move under the action of external force to be separated from the limiting piece. The invention further provides an unmanned aerial vehicle adopting the propeller assembly. According to the propeller assembly and the unmanned aerial vehicle, the technical problems that in the prior art, due to the inertia effect of the blades, the unmanned aerial vehicle flies unstably, and the blades are seriously abraded can be solved.

    本发明提供了一种螺旋桨组件及无人机,涉及无人机技术领域。该螺旋桨组件包括桨叶、安装主体、限位件和活动件。桨叶可转动地连接于安装主体,且能相对安装主体转动至展开状态。限位件固定在桨叶上,活动件活动设置在安装主体上。在桨叶处于展开状态的情况下,限位件与活动件卡接以使限位件相对安装主体固定。活动件能在外力作用下移动以脱开限位件。本发明还提供了一种无人机,其采用了上述的螺旋桨组件。本发明提供的螺旋桨组件及无人机能解决现有技术中由于桨叶惯性作用造成的无人机飞行不稳定,以及桨叶磨损严重的技术问题。
