Abstract

The invention discloses a human-like lower limb system. Oscillating cylinders are used as power elements to drive hip joints, knee joints and ankle joints to move, and the human-like lower limb systemhas the function of completely simulating the lower limb movement of a human body. An artificial lower limb is mainly composed of thigh components, shank components, feet, self-lubricating ball headrod end knuckle bearings, the oscillating cylinders, belt wheels and connecting parts. the plurality of oscillating cylinders drive branch chains composed of parallel rods to form the hip joints capable of stretching, unfolding and rotating in a space, the ankle joints and the plurality of oscillating cylinders move up and down through the belt wheels to form the knee joints capable of stretching,and the hip joints capable of unfolding and unfolding. The human-like lower limb system is driven by the oscillating cylinders, and has the characteristics of being compact in structure, not prone tobeing blocked, good in flexibility and the like, and can be used for teaching and exhibition.

Description

technical field

[0001] The invention belongs to the technical field of robots and relates to a humanoid lower limb system. Background technique

[0002] In order to liberate human beings from heavy and dangerous work, robot technology has developed rapidly in the fields of anti-terrorism, disaster relief, and industrial automation production. A large part of the robot design concept is based on the functional research of human beings. Since the characteristics of pneumatic muscles are similar to those of human muscles, Chinese patent 201410040899.X designed a humanoid lower limb with mixed pneumatic muscles, and Chinese patent 201510501302.1 designed a humanoid lower limb driven by a pair of pneumatic muscles. Chinese patent 201611119891.8 designed a humanoid lower limb driven by vertical cross motors in three directions of XYZ, but it has the characteristics of small movement space, poor carrying capacity and easy to get stuck.
