A magnetically-driven flexible manta ray-imitated flapping wing structure comprises a sleeve shell made of a flexible material and a plurality of electromagnetic driving chains connected to the sleeve shell, each electromagnetic driving chain comprises at least two magnetic bearing sheets and a plurality of skeleton units, the magnetic bearing sheets and the skeleton units are sequentially connected at intervals from left to right, the adjacent magnetic bearing sheets are oppositely arranged, and the magnetic bearing sheets and the skeleton units are oppositely arranged. The two ends of each framework unit are connected to the middles of the two adjacent magnetic bearing pieces respectively, so that the two adjacent magnetic bearing pieces can rotate relatively, and electromagnets are arranged on the upper portion and the lower portion of the side, facing the adjacent magnetic bearing pieces, of any magnetic bearing piece respectively. According to the electromagnetic driving chain in the scheme, the bionic pectoral fin can have two propelling modes of active deformation and passive deformation at the same time, active flapping of the bionic pectoral fin can be achieved in the mode of changing the polarity direction of the electromagnets, and passive bending deformation of the bionic pectoral fin can be achieved through sequential spaced connection of the magnetic bearing pieces and the framework units; therefore, the robot has the advantages of being good in bionic effect, accurate in action, large in bending amplitude, flexible in swinging, large in propulsive force and the like, has good practicability and is beneficial to application and popularization.
一种磁力驱动的柔性仿蝠鲼扑翼结构,包括由柔性材料制成的套壳和连接于套壳的若干条电磁驱动链,电磁驱动链包括至少两个承磁片和若干骨架单元,承磁片和骨架单元沿从左向右依次间隔连接,相邻的承磁片相对设置,骨架单元的两端分别连接于相邻两个承磁片的中部并使得相邻两个承磁片可相对转动,任一承磁片的朝向相邻承磁片的一侧的上部和下部分别设有电磁铁。上述方案的电磁驱动链使得仿生胸鳍能够同时具备主动变形与被动变形的两种推进模式,既能以改变电磁铁极性方向的方式实现仿生胸鳍的主动扑动,又能以承磁片和骨架单元的依次间隔连接实现仿生胸鳍的被动的弯曲变形,从而具有仿生效果好、动作准确、弯曲幅度大、摆动灵活、推进力大等优点,具备较好的实用性,利于推广应用。
