The invention discloses a wing folding structure for an unmanned aerial vehicle. The unmanned aerial vehicle comprises a fuselage and two wings symmetrically arranged on the two sides of the fuselage; one end of one side of each wing is hinged to the fuselage, the other end of one side of each wing is hinged to a multi-connecting-rod mechanism, the multi-connecting-rod mechanism is hinged to a straight rod through a connecting shaft, an arc groove is formed in the fuselage, the connecting shaft can slide along the arc groove, a driving piece is arranged at the other end of the straight rod, and the driving piece is connected with the multi-connecting-rod mechanism. The driving part is in driving connection with the straight rod, the driving direction of the driving part is arranged along the length direction of the fuselage, and the driving part drives the straight rod to linearly move so as to drive the wings on the same side to be unfolded or folded. The wing folding structure adopts a full connecting rod form to realize large-angle wing backsweep, and can be popularized to unmanned aerial vehicles with slightly large structures.
本发明公开了一种用于无人机的机翼折叠结构,包括:所述无人机包括机身和对称设置在所述机身两侧的两个机翼;每个所述机翼一侧的一端与所述机身铰接,另一端与一多连杆机构铰接,所述多连杆机构通过一连接轴与一直杆铰接,所述机身上设置有一圆弧槽,所述连接轴可沿所述圆弧槽滑动,所述直杆的另一端设置有驱动件,所述驱动件与所述直杆驱动连接,所述驱动件的驱动方向沿所述机身的长度方向设置,所述驱动件驱动所述直杆直线运动,进而带动同侧的所述机翼展开或者折叠。该机翼折叠结构采用全连杆形式实现大角度的机翼后掠,且可将其推广到结构稍大型的无人机中。
