The invention discloses a passive wing telescopic structure, and relates to the technical field of aviation aircraft design. The problems that an existing unmanned aerial vehicle is large in wingspan, large in occupied space, high in maintenance cost and large in probability of being detected and found are solved. The unmanned aerial vehicle comprises a wing, a telescopic wing, a linkage rope, a traction mechanism and a resettable telescopic mechanism, a slot is formed in the middle of the front end face of the wing, the tail end of the telescopic wing is inserted into the slot, the telescopic wing is connected with the wing through the resettable telescopic mechanism, one end of the linkage rope is fixedly connected with the tail end of the telescopic wing, the other end of the linkage rope penetrates through the groove bottom of the inserting groove and then is connected with a control mechanism located on the fuselage, and the linkage rope controls the telescopic wings to stretch out and draw back through a traction mechanism. According to the working principle of the movable pulley, the compression spring is adopted as a driving part, the compression stroke of the elastic part is shortened, the machining difficulty of the elastic part is reduced, other power sources are not needed, the influence of high altitude and low temperature is avoided, and the system can be applied to different unmanned aerial vehicles as an independent system.

    一种被动式机翼伸缩结构,它涉及航空飞行器设计技术领域。本发明为解决现有无人机翼展过大导致占用空间大、维护成本高、被侦察发现的几率大的问题。本发明包括机翼、伸缩翼、联动绳索、牵引机构和可复位伸缩机构,机翼前端面的中部设有插槽,伸缩翼的末端插装在插槽内,伸缩翼通过可复位伸缩机构与机翼连接,联动绳索的一端与伸缩翼的末端固接,联动绳索的另一端穿过插槽的槽底后与位于机身的控制机构连接,联动绳索通过牵引机构控制伸缩翼伸缩。本发明利用动滑轮工作原理,采用压缩弹簧作为驱动件,缩减了弹性件的压缩行程,降低了弹性件的加工难度,不需要其他动力源,不受高空低温影响,可作为一个独立的系统应用于不同的无人机上。
