The invention relates to a flapping wing structure imitating dragonfly wings. The flapping wing structure is characterized by comprising fold-line-shaped wing ribs, a wing spar and a thin film, wherein the number of the fold-line-shaped wing ribs is multiple, and the number of the wing beams is multiple; each fold-line-shaped wing rib is a strip-shaped piece, and the strip-shaped pieces form a fold line shape which is alternately bent in the forward direction and the reverse direction; each fold-line-shaped wing rib is provided with at least two forward bends and at least two reverse bends; aplurality of fold-line-shaped wing ribs are longitudinally arranged at intervals, a plurality of wing beams are transversely arranged at intervals, and a plurality of fold-line-shaped wing ribs and aplurality of wing beams are connected to form a grid type frame structure; and the film covers the grid type frame structure and is fixed into a whole. The structure is advantaged in that rigidity ofthe whole wing is remarkably enhanced, and under the condition of bearing the same load, the deformation of the wing is only equivalent to one tenth of that of a wing in the prior art, especially a plane frame wing.
本发明涉及一种仿蜻蜓翼翅的扑翼结构,其特征在于:所述扑翼结构包括折线形状翼肋、翼梁和薄膜;所述折线形状翼肋为多个,所述翼梁为多个;每个折线形状翼肋均为条形件,且所述条形件形成正向和反向交替弯折的折线形状;每个折线形状翼肋具有至少2个正向弯折和至少2个反向弯折;多个折线形状翼肋呈纵向间隔布置,多个翼梁呈横向间隔布置,且多个折线形状翼肋与多个翼梁连接为网格型框架结构;所述薄膜覆盖在网格型框架结构上固定为一体。本发明的整体机翼的刚度显著增强,在承受相同载荷的情况下,机翼的变形只相当于现有技术的机翼,尤其是平面框架机翼的十分之一。
