The invention discloses a telescopic comprehensive protection device for an unmanned helicopter, and relates to the technical field of unmanned helicopters. The telescopic comprehensive protection device comprises a machine body, wherein a movable telescopic device is fixedly connected to a middle end of the bottom of the machine body, racks are fixedly connected to the two sides of the bottom of the machine body, and a cross rod is fixedly connected to one side of each rack; and a main rotor wing is arranged on an outer wall of the top of the vehicle body. Through the arrangement of the movable telescopic device, safety protection can be conveniently conducted on the bottom and the side face of the helicopter body, the situation that the helicopter body is damaged by impact force generated when the helicopter lands is prevented, and when impact is generated, the impact will firstly make contact with the protruding part outside the helicopter body, namely the position of the protection barrel; a lower protection barrel, a reset spring and an upper protection barrel protect the helicopter body at the same time, the protection effect is better while the protection range of the protection barrels is enlarged, the protection structure is convenient to stretch and fold through the movable telescopic device, the telescopic rope is controlled through the telescopic rod to retract, the protection barrels are convenient to move back to the interior of the extrusion groove, and normal flight of the helicopter cannot be affected.
本发明公开了一种无人直升机用可伸缩的全面防护装置,涉及无人直升机技术领域,包括机体,所述机体的底部中端固定连接有移动伸缩装置,所述机体的底部两侧固定连接有机架,所述机架的一侧固定连接有横杆,所述机体的顶部外壁设置有主旋翼。通过移动伸缩装置的设置,方便对直升机机体的底部和侧面进行安全防护,防止直升机降落时的冲击力对机体造成损坏,产生撞击时会先与机身外部突出的部分接触即防护筒的位置接触,下防护筒、复位弹簧和上防护筒同时对机体进行防护,防护筒的防护范围变大的同时防护效果更好,且防护结构通过移动伸缩装置方便伸缩折叠,通过伸缩杆控制伸缩绳的收缩,防护筒方便移回挤压槽的内部,不会影响直升机的正常飞行。
