The invention discloses a bionic flapping wing driving mechanism with flexible self-adaptive flapping angle, which comprises a shell, flapping wings and a driving mechanism, the driving mechanism is arranged in the shell, two sides of the shell are symmetrically provided with notches, the two flapping wings are symmetrically mounted on two sides of the shell, and the flapping wings are arranged in the notches. The output end of the driving mechanism performs single-side output on the two flapping wings, each flapping wing comprises a rigid frame and a flexible wing surface, the rigid frame is of a wing-shaped structure, the edge of the flexible wing surface is fixedly connected to the rigid frame, the flexible wing surface is formed by compounding a plurality of layers of flexible materials, each layer of flexible material is formed by coating from inside to outside, and the flexible wing surface is formed by coating a plurality of layers of flexible materials from inside to outside. The flexibility of each layer of flexible material is gradually improved from inside to outside, and the device transmits fluctuating motion in a longitudinal wave mode by means of interaction between the flexible flapping wing media and fluid to achieve propelling, so that the problems that an existing fusiform bionic structure is limited by a two-degree-of-freedom structure, high in cost and low in cohesion are solved.
本发明公开了一种带有柔性自适应拍动角度的仿生扑翼驱动机构,包括外壳、扑翼和驱动机构,所述驱动机构设置在外壳内,所述外壳两侧呈对称结构设置有缺口,两个所述扑翼呈对称结构安装在外壳两侧,所述驱动机构的输出端对两个扑翼单边输出,所述扑翼包括刚性架和柔性翼面,所述刚性架呈机翼状结构,所述柔性翼面的边缘处固定连接在刚性架上,所述柔性翼面有若干层柔性材料复合而成,每层所述柔性材料由内向外包覆而成,每层所述柔性材料的柔软度由内向外逐渐提高,该装置依靠柔性扑翼介质本身与流体间的相互作用以纵波的方式传递波动运动来实现推进,以解决目前纺锤形仿生结构二自由度结构限制、高成本、低内聚的问题。
