The invention provides a mechanical bionic fish dimension-shaped structure which comprises a plurality of independent dimension-shaped structure units, the dimension-shaped structure units are connected through rotating shafts, and the dimension of each dimension-shaped structure unit is gradually reduced from head to tail according to the size of a fish body so that the outer contour can be in a fish shape. Each dimensional structure unit comprises a dimensional shell and dimensional prongs, the dimensional prongs between every two adjacent dimensional units are matched in a crossed mode, and the shapes of the dimensional shells between every two adjacent dimensional units are matched so that the dimensional structure units can freely rotate without interference. According to the shape-maintaining structure, it is guaranteed that the shape-maintaining structure does not fall off or deform in the bionic fish swimming process, the problems of bionic skin wrinkling and sinking caused by fish body bending are solved, the movement flexibility of the shape-maintaining structure of the bionic mechanical fish is effectively improved, the strength of the shape-maintaining structure is improved, and the simulation degree of the bionic mechanical fish is improved.

    本发明提供一种机械仿生鱼维形结构,包括多节各自独立的维形结构单元,所述维形结构单元之间通过旋转轴连接,各个所述维形结构单元根据鱼体的大小从首至尾尺寸逐渐变小使外轮廓呈鱼形,所述维形结构单元包括维形壳和维形叉齿,所述相邻两个维形单元之间的维形叉齿交叉配合,所述相邻两个维形单元之间的维形壳形状相配合使维形结构单元可以自由转动并且无干涉。本发明既保障维形结构在仿生鱼游动过程中,不脱落,不变形,又改善鱼体弯折而导致的仿生蒙皮褶皱及凹陷问题,本发明有效提高仿生机械鱼的维形结构的运动灵活性,提高了维形结构的强度,提高仿生机械鱼的仿真度。
