The invention relates to the technical field of unmanned aerial vehicles, in particular to an anti-falling slow-descent type unmanned aerial vehicle and a using method thereof.The anti-falling slow-descent type unmanned aerial vehicle comprises a main vehicle body, and further comprises side supporting rods rotationally arranged above the rotating supporting seat; fixed locking rings are arranged on the outer side of the polygonal supporting rod at intervals in a surrounding mode. A plurality of horizontal support arms arranged around the outer side of a support turntable are connected and fixed with a motor support, a multilateral support rod keeps locking and fixing a tilting spring during normal flight, and when the unmanned aerial vehicle breaks down, a sliding locking ring can slide downwards to unlock the multilateral support rod so that the multilateral support rod can rotate; and then the supporting rotating disc reversely pushes the slow descending blades on the multiple horizontal supporting arms to rotate around the multilateral supporting rod through air resistance when the unmanned aerial vehicle falls, so that certain lift force is generated, the falling resistance is improved, the falling speed is reduced, the whole unmanned aerial vehicle can slowly land, and the safety of the unmanned aerial vehicle is improved.

    本发明涉及无人机技术领域,具体涉及一种防坠落缓降式无人机及其使用方法,包括:括有主机体,所述主机体的中心处设置有旋转支撑座,还包括:边支撑杆,转动设置于所述旋转支撑座的上方,所述多边支撑杆的外侧间隔环绕设置有固定锁定环。本发明通过支撑转盘外侧环绕设置的多个水平支臂连接固定电机支座,在正常飞行时多边支撑杆保持锁定固定倾转弹簧,而无人机发生故障时,滑动锁定环可以向下滑动解锁多边支撑杆使其可以转动,进而使支撑转盘在无人机下坠时通过空气阻力反向的推动多个水平支臂上的缓降叶片围绕多边支撑杆转动,以产生一定升力提高下落阻力并降低坠落速度,使无人机整体能够缓慢降落,有利于提高无人机的安全性。
