The invention discloses a bionic fish structure capable of being folded, unfolded and adjusted in variable stiffness, belongs to the technical field of bionic fish structures, and aims at solving the problems that an existing bionic fish is large in energy loss rate, low in swimming speed and poor in stability during high-speed swimming, and a large amount of space cannot be vacated in a fish head for bearing. The fish comprises a fish head unit, a fish body unit and a foldable tail fin, the fish head unit and the foldable tail fin are arranged at the two ends of the fish body unit respectively, and the fish body unit comprises an outer side framework, a foldable back fin unit, a fish body swing unit and a fish tail variable rigidity adjusting assembly. The foldable back fin unit, the fish body swinging unit and the fish tail variable stiffness adjusting assembly are all arranged in the outer side framework, one end of the fish body swinging unit is detachably connected with the fish head unit, and the other end of the fish body swinging unit extends out of the tail end of the outer side framework and is detachably connected with the foldable tail fin; the foldable dorsal fin unit is located above the fish body swing unit, the top of the foldable dorsal fin unit penetrates through the outer side framework and extends to the position above the outer side framework, and the fishtail variable rigidity adjusting assembly is located above the fish body swing unit and inside the outer side framework. The bionic fish structure is used for underwater detection.

    一种兼具可折展与变刚度调节的仿生鱼结构,属于仿生鱼结构技术领域,本发明为解决现有仿生鱼能量损耗率大,游动速度较慢、高速游动时稳定性较差以及鱼头内部无法腾出大量空间承载的问题,本申请包括鱼头单元、鱼体单元和可折展尾鳍,鱼头单元和可折展尾鳍分别设置在鱼体单元的两端,鱼体单元包括外侧骨架、可折展背鳍单元、鱼身摆动单元和鱼尾变刚度调节组件,可折展背鳍单元、鱼身摆动单元和鱼尾变刚度调节组件均设置在外侧骨架中,且鱼身摆动单元的一端与鱼头单元拆卸连接,鱼身摆动单元的另一端延伸出外侧骨架的尾端并于可折展尾鳍可拆卸连接,可折展背鳍单元位于鱼身摆动单元的上方,且可折展背鳍单元的顶部穿过外侧骨架并延伸至外侧骨架的上方,鱼尾变刚度调节组件位于鱼身摆动单元上方,外侧骨架内部。本申请用作一种水下探测的仿生鱼结构。
