The invention discloses a bionic bird lower limb transmission mechanism model, belongs to the field of bionic robots, and aims to realize the bouncing take-off and grabbing functions of a bionic mechanical bird. The mechanism comprises a leg tibia-tarsal bone (1), a rolling line pulley (2), a gear rod meshing joint positioning clamping plate (3), a leg tarsal-metatarsal bone (4), a bird claw (5), a bird toe (6), a bird sole (7) and a lower limb clamping device (8), an executing mechanism drives leg structures on the two sides to move synchronously in a steering engine rope combination mode, the foot grabbing action is conducted when the leg is bent, and a rod system spring is stretched to store elastic potential energy. When the legs extend, the feet are opened, the stored elastic potential energy is released, the wings of the bionic bird flutter, and then the bouncing take-off action of the aircraft body is completed. The lower limb device is novel in structure and excellent in bionic performance, perfects the take-off, landing and flying functions of bionic birds, and has wide military reconnaissance application prospects.

    本发明公开了一种仿生鸟下肢传动机构模型,属于仿生机器人领域,目的在于实现仿生机械鸟的弹跳起飞及抓取功能。其机构包含腿部胫跗骨(1)、滚线滑轮(2)、齿轮杆啮合关节定位夹板(3)、腿部跗跖骨(4)、鸟脚爪(5)、鸟脚趾(6)、鸟脚掌(7)、下肢卡死装置(8),执行机构以舵机绳索组合的形式驱动两侧腿部结构进行同步运动,屈腿时进行脚部抓取动作,杆系弹簧拉伸储存弹性势能。伸腿时脚部张开,释放储存的弹性势能,仿生鸟翅膀扑动,进而完成机体的弹跳起飞动作。本发明的下肢装置结构新颖,仿生性能优秀,完善了仿生鸟起降飞行的功能,具有广阔的军事侦察应用前景。
