The invention relates to the technical field of unmanned aerial vehicles, in particular to a telescopic unmanned aerial vehicle protection device which comprises an unmanned aerial vehicle body, an undercarriage and a plurality of protection assemblies, each protection assembly comprises a rotating rod, a first air cylinder, two side rods, a supporting rod, a first spring and a pull wire, and during normal flight, the rotating rods are stored in a supporting frame to reduce flight resistance; in a flight area with numerous obstacles, a rotating rod can be rotated, then a first air cylinder is driven to drive a supporting rod to stretch out, and when the supporting rod stretches out, the two side rods can be pushed away through a first spring, so that a pull wire is pulled open to cover the area where the blades are located; the supporting rods are arranged on the side plates, so that buffering and protection can be performed through a frame formed by the pulling wires and the side plates during collision to protect the blades, the supporting rods can be retracted after the blades pass through an obstacle area, the rotating rods are close to the supporting frames to continue flying, protection can be properly provided, flying is not affected, and flying energy consumption is reduced.
本发明涉及无人机技术领域,具体涉及一种可伸缩无人机保护装置,包括无人机主体、起落架和多个保护组件,保护组件包括转动杆、第一气缸、两个侧杆、支撑杆、第一弹簧和拉线,在正常飞行时,转动杆收纳到支撑架中以减少飞行阻力,而在具有众多障碍物的飞行区域,则可以转动转动杆,然后驱动第一气缸带动支撑杆伸出,在支撑杆伸出的同时,通过第一弹簧的他那里可以将两个侧杆推开,从而将拉线拉开以对叶片所在区域进行覆盖,从而可以在撞击时通过拉线和侧板形成的框架进行缓冲和保护,以对叶片进行保护,待通过障碍区域后则可以缩回支撑杆,并将转动杆靠近支撑架,以继续飞行,从而可以适当地提供保护又不会影响飞行,以降低飞行能耗。
