The blade protection device of the unmanned aerial vehicle comprises a rotary disc, a plurality of connecting assemblies, a plurality of protection assemblies, a plurality of distance sensors and a controller, the rotary disc is rotationally arranged on the lower surface of a vehicle body, and the rotary disc is connected with a motor; a plurality of machine arms are arranged on the side wall of the machine body, a lantern ring is arranged on each machine arm in a sliding mode, and a supporting plate is arranged on each lantern ring; one end of each connecting assembly is hinged to the corresponding supporting plate, and the other end of each connecting assembly is hinged to the rotating disc; the multiple protection assemblies are connected with the corresponding lantern rings respectively, and the distance sensor is arranged on the lower surface of the bearing table. The controller is installed in the machine body and connected with the distance sensor and the motor. Therefore, the protection assembly can be controlled to be unfolded or retracted, and the protection assembly can be unfolded to protect the blades when needed; and the blades can retract when not needed, so that the air resistance around the blades is reduced, the flight efficiency of the unmanned aerial vehicle is improved, and the flight flexibility is improved.
本申请公开了一种无人机的叶片保护装置,包括转盘、多个连接组件、多个防护组件、多个距离传感器和控制器,转盘转动设置在机身的下表面,且转盘与电机相连;机身的侧壁上设有多个机臂,每个机臂上均滑动设有套环,套环上设有支撑板;多个连接组件的一端分别与对应的支撑板铰接,多个连接组件的另一端与转盘铰接;多个防护组件分别与对应的套环相连,距离传感器设置在承载台的下表面;控制器安装在机身的内部,且控制器分别与距离传感器和电机相连。由此,能够控制防护组件展开或缩回,在需要时,防护组件会展开以保护叶片;而在不需要时会缩回,以降低叶片周围的空气阻力,提升无人机的飞行效率并增加飞行的灵活性。
