Flexible bionic joint and robot

Abstract

The invention discloses a flexible bionic joint and a robot. The flexible bionic joint comprises a driving part and a joint assembly. The driving part comprises an output shaft. The joint assembly comprises a first rotary part and a second rotary part adjacent to the first rotary part. The first rotary part comprises a first rotary wheel and a second rotary wheel. The second rotary wheel and the first rotary wheel are coaxially fixed. The second rotary part comprises a third rotary wheel. The flexible bionic joint also comprises a first rotary part and a second rotary part. The first rotary part bypasses the output shaft and the first rotary wheel. The second rotary part bypasses the second rotary wheel and the third rotary wheel. The technical scheme is intended to reduce the overall weight of exoskeleton and achieves a compact installation space. The reasonable configuration of transmission ratios is achieved, which is conducive to achieving overload protection. The flexible bionic joint is convenient to use.

Description

technical field [0001] The invention relates to the technical field of legged robots and exoskeleton robots, in particular to a flexible bionic joint and a robot. Background technique [0002] With the development of science and technology, legged robots are widely used in industry and service industries; robots are widely used in military and industrial load-bearing assistance, as well as medical and rehabilitation occasions for helping the elderly and the disabled. Existing legged robots or wearable exoskeleton robots have high requirements on the output of each active joint, and need to meet the high-speed, high-efficiency use effect and support the wearer's own weight, thereby assisting the wearer to complete normal assistance. or recovery activities. [0003] In order to meet high-speed and high-torque output, motors are often used to cooperate with gears, pulleys and other reduction mechanisms with large volume and mass, or hydraulic drives are used to cooperate with ...

AI Technical Summary

Problems solved by technology

[0003] In order to meet high-speed and high-torque output, motors are often used to cooperate with gears, pulleys and other reduction mechanisms with large volume and mass, or hydraulic drives are used to cooperate with hydraulic pump stations, and the overall mass is larger. In limited space or quality constraints In this situation, it is difficult to meet the configuration of a reasonable transmission ratio, and because its transmission is a rigid component such as a gear pair, it is not conducive to the realization of overload protection, resulting in inconvenient wearing and inflexible movement of the human body, which is not conducive to use
