Hydraulic driving flexible robot joint

Abstract

The invention belongs to the field of bio-robots, and discloses a hydraulic driving flexible robot joint which comprises a thigh structure, a thigh-crus connecting frame and a crus structure. The thigh structure comprises a thigh body frame, a cylinder seat, a hydraulic cylinder, a movable frame, a guide shaft and a compression spring. The crus structure comprises a crus body frame, a guide rail and a slide block. The crus body frame is hinged to the thigh body frame. The guide rail is installed on the crus body frame. The slide block is installed on the guide rail. One end of the thigh-crus connecting frame is hinged to the thigh body frame, and the other end of the thigh-crus connecting frame is hinged to the slide block. In addition, the thigh-crus connecting frame is hinged to the end, away from the hydraulic cylinder, of the guide shaft. The hydraulic driving flexible robot joint can adapt to changes of external loads, have the bionic flexible characteristic and force arm characteristics, meet motion requirements of a robot, and can effectively reduce the total weight, achieve lightweight and improve the motion efficiency.

AI Technical Summary

Benefits of technology

This new technology allows for better control over robots that use hydrauled actuators due to its flexible connection between them and increased power-to-motion ratio during operation. It also improves the performance and lifespan of these robotic systems while reducing their size and mass.

Problems solved by technology

This patented describes how different parts on a robot can affect their behavior during movement or use by causing them to behave differently when they move around with varying speeds. These differences may lead to reduced overall functionality and weightiness issues that limit the ability of these components to function properly. Therefore, this technical solution involves developing new methods for controlling the movements of certain parts within the robot's body without adding extra weights or complicated mechanisms.
