The invention discloses a wing folding mechanism which comprises a wing, the wing comprises an inner wing section and two outer wing sections, the two ends of the inner wing section are connected with the two outer wing sections respectively, an inner wing main beam of the inner wing section is rotationally connected with outer wing main beams of the outer wing sections, and an inner wing auxiliary beam of the inner wing section is rotationally connected with outer wing auxiliary beams of the outer wing sections; a rotary steering engine is arranged at the end of the inner wing section, an output shaft of the rotary steering engine is connected with the head end of a folding pull rod, the tail end of the folding pull rod is hinged to the outer wing auxiliary beam close to the outer end of the outer wing section, a linear steering engine is arranged at the end of the inner wing section, and a reinforcing wing rib is arranged at the end of the inner end of the outer wing section. Limiting holes correspondingly matched with execution rods of the linear steering engines are formed in the reinforcing wing ribs; the large-span wing of the unmanned aerial vehicle is folded or unfolded, a connecting structure with a reinforced structure is arranged between the inner wing section and the outer wing section of the wing, the wing structure in the unfolded state has the same mechanical performance as a traditional integrated wing structure, and the flight efficiency and the flight safety of the unmanned aerial vehicle are improved.

    本发明公开一种机翼折叠机构,包括机翼,机翼包括内翼段和两个外翼段,内翼段的两端分别与两个外翼段连接,内翼段的内翼主梁与外翼段的外翼主梁之间转动连接,内翼段的内翼副梁与外翼段的外翼副梁之间转动连接,在内翼段的端部设置旋转舵机,旋转舵机的输出轴与折叠拉杆的首端连接,折叠拉杆的尾端与靠近外翼段外端的外翼副梁铰接,在内翼段的端部设置直线舵机,在外翼段内端的端部设置加强翼肋,在加强翼肋上设置与直线舵机的执行杆对应配合的限位孔;本发明使无人机的大展长机翼折叠或展开,机翼内翼段与外翼段之间具有结构加强的连接结构,使展开状态下的机翼结构与传统一体式机翼结构具有相同的机械性能,提高无人机飞行效率和飞行安全性。
