The invention discloses a propeller retracting and releasing device for an anti-falling unmanned aerial vehicle, and particularly relates to the technical field of unmanned aerial vehicles, the propeller retracting and releasing device comprises a fuselage, an elastic parachute structure is arranged at the upper end of the fuselage, and the lower end of the fuselage and the lower end of a battery box are jointly and fixedly connected with a buffer structure; the four corners of the inner surface of the fuselage are fixedly connected with annularly-distributed propeller folding and unfolding structures through bolts correspondingly, and rotor wing structures are arranged at the ends, away from the fuselage, of the multiple propeller folding and unfolding structures correspondingly. According to the propeller folding and unfolding device for the anti-falling unmanned aerial vehicle, the spiral arm is folded through the propeller folding and unfolding structure, the posture adjusting assembly is unfolded in the folding process through cooperation of the propeller folding and unfolding structure and the spiral arm, and the falling posture and speed are subjected to auxiliary adjustment through the posture adjusting assembly; and meanwhile, the falling speed of the unmanned aerial vehicle is further reduced through the action of the parachute structure, and the probability that parts are damaged due to high-altitude falling is reduced.

    本发明公开了一种用于防坠无人机的螺旋桨收放装置,具体涉及无人机技术领域,包括机身,所述机身上端设置有弹伞结构,所述机身下端与电池盒下端共同固定连接有缓冲结构,所述机身内表面四角均通过螺栓固定连接有环形分布的螺旋桨收放结构,若干所述螺旋桨收放结构远离机身的一端均设置有旋翼结构。本发明所述的一种用于防坠无人机的螺旋桨收放装置,通过螺旋桨收放结构将旋臂收起,并通过螺旋桨收放结构和旋臂的配合在收起过程中将姿态调节组件展开,通过姿态调节组件对坠落姿态与速度进行辅助调节,避免坠落速度过快导致落地后受到较大的冲击,同时通过弹伞结构的作用进一步降低无人机的坠落速度,减少高空坠落导致的零部件损坏概率。
