The invention discloses a folding and unfolding device of an aircraft. The two ends of the second rotating seat are rotationally connected to the first rotating seat and the machine body correspondingly and located on the outer side of the rotating shaft; the sides, away from the rotating shaft, of the first rotating seat and the second rotating seat are connected to the corresponding inner wings correspondingly. The inner wall of the first rotating seat, the inner wall of the second rotating seat, the outer wall of the rotating shaft and the machine body form a containing space; the second elastic piece, the telescopic driving mechanism and the telescopic triggering mechanism are all arranged in the accommodating space; the second elastic piece is arranged on the telescopic driving mechanism in a sleeving mode, the two ends of the second elastic piece are connected to the first rotating base and the second rotating base respectively, and the second elastic piece has pre-tightening force when the two inner wings are folded; the telescopic triggering mechanism is arranged between the machine body and the first rotating seat; the two telescopic mechanisms are arranged between the telescopic driving mechanisms and the outer wings corresponding to the telescopic driving mechanisms respectively. When the two inner wings are unfolded in place, the outer wings stretch out, the aerodynamic resistance of the wings in the unfolding process is reduced, and the energy consumption of the whole structure is reduced.

    本申请公开了一种飞行器的折叠和展开装置。第二转动座的两端分别转动连接于第一转动座和机身,且位于旋转轴的外侧;第一转动座和第二转动座远离旋转轴的一侧分别连接于与之对应的内翼;第一转动座的内壁、第二转动座的内壁、旋转轴的外壁和机身形成容纳空间;第二弹性件、伸缩驱动机构和伸缩触发机构均设置于容纳空间内;第二弹性件套设于伸缩驱动机构,其两端分别连接于第一转动座和第二转动座,且第二弹性件在两个内翼折叠时,具有预紧力;伸缩触发机构设置于机身和第一转动座之间;两个伸缩机构分别设置于伸缩驱动机构和与之对应的外翼之间。本申请在两个内翼展开到位时,外翼伸出,减少机翼在展开过程中的气动阻力,降低整体结构耗能。
