The invention relates to the technical field of water-air cross-medium motion robots, in particular to a bionic frog leg jumping mechanism which comprises a water breaking assembly, thigh rod pieces, an elastic potential energy storage assembly, shank rod pieces, a connector and a water treading assembly, one end of each thigh rod piece is hinged to the bottom of the water breaking assembly, and the other end of each thigh rod piece is hinged to the bottom of the water treading assembly; one ends of the two shank rod pieces are hinged to the other ends of the two thigh rod pieces through first cylindrical pins respectively, the elastic potential energy storage assembly is installed between the two first cylindrical pins, the other ends of the two shank rod pieces are hinged to the connector respectively, the water treading assembly comprises two flat flippers, and the two flippers are connected with the elastic potential energy storage assembly. One ends of the two flippers are hinged to the connector, and the other ends of the two shank rod pieces are in transmission connection with one ends of the two flippers. The jumping mechanism is small in size, simple in structure, small in resistance when jumping in a water medium and suitable for water-air cross-medium jumping.

    本发明涉及水‑空跨介质运动机器人的技术领域,更具体地,涉及一种仿生蛙类腿部的跳跃机构,包括破水组件、大腿杆件、弹性势能存储组件、小腿杆件、连接器和踩水组件,两个所述大腿杆件的一端分别与所述破水组件的底部铰接,两个所述小腿杆件的一端分别与两个所述大腿杆件的另一端通过第一圆柱销铰接,所述弹性势能存储组件安装于两个所述第一圆柱销之间,两个所述小腿杆件的另一端分别与所述连接器铰接,所述踩水组件包括两个呈扁平状的脚蹼,两个所述脚蹼的一端分别与所述连接器铰接,且两个所述小腿杆件的另一端与两个所述脚蹼的一端传动连接。本发明的跳跃机构体积小、结构简单、在水介质中跳跃时阻力小,适用于水‑空跨介质跳跃。
