The invention provides a bionic frog bouncing device which comprises a bionic shell, a mounting shaft and a front supporting part are arranged at the bottom of the bionic shell, a rear leg disc is hinged to the mounting shaft, the bionic shell is provided with a rear sole, and the rear sole is connected with the rear leg disc through a connecting rod mechanism. A torsional spring is wound on the installation shaft, the two ends of the torsional spring are connected with the bionic shell and the rear leg disc respectively, and an energy storage mechanism capable of intermittently driving the torsional spring to contract is arranged at the bottom of the bionic shell. And a limiting mechanism capable of limiting the end part of the contracted torsion spring is arranged on the rear leg disc. The device can simulate continuous bounce of the frog, the rear leg disc and the rear sole do not have leg retracting actions when bounce is started, the take-off action when the real frog takes off can be simulated, and the device is more in line with the real situation that muscles accumulate force and limbs do not move when the real frog is ready to take off.
本发明提供了一种仿生青蛙弹跳装置,包括有仿生外壳,仿生外壳底部设置有安装轴和前支撑部,安装轴上铰接有后腿盘,仿生外壳设置有后脚掌,后脚掌与后腿盘通过连杆机构进行连接,后腿盘在转动的过程中可通过连杆机构驱动后脚掌做蹬腿动作,安装轴上绕设有扭簧,扭簧两端分别与仿生外壳和后腿盘连接,仿生外壳底部设置有可间歇驱动扭簧收缩的蓄能机构,后腿盘上设置有可对收缩后的扭簧端部限位的限位机构。该装置可模拟青蛙的连续弹跳,且在弹跳启动时后腿盘和后脚掌无收腿动作,能模拟真实青蛙起跳时的起跳动作,更加符合真实青蛙的预备起跳时肌肉蓄力而肢体不移动的真实情况。
