Abstract

A high-load-bearing truss type high-flexibility mechanism relates to a flexible mechanism. The invention aims to solve the problem that the existing flexible mechanism is not suitable for complex and flexible deformation and the deformation range is limited. The present invention comprises a plurality of truss units, a plurality of hinges, a plurality of sliders, a plurality of actuating mechanisms and a plurality of flexible rods. The plurality of truss units are sequentially connected as a whole through the hinges, and the sliders are fixedly connected to the hinges as a whole. The actuator is fixedly connected with the slide block, the slide block is sleeved on the flexible rod, and the slide block moves along the flexible rod driven by the actuator. The present invention is used for deformable equipment.

Description

technical field [0001] The invention relates to a flexible mechanism, in particular to a high-load-bearing truss type high-flexibility mechanism. Background technique [0002] Mechanical equipment often needs to achieve functions through controllable changes in shape. Traditional mechanisms such as articulated robotic arms, slide rails, and pistons often use rigid parts connected by kinematic pairs to achieve deformation and carry external forces. They have the characteristics of simple mechanisms and simple motion mechanisms. , but its deformation range is often limited by rigid components, and the position of each point of the mechanism during the deformation process often has a simple linear coupling and is not easy to form a complex and controllable shape. [0003] In recent years, with the development of equipment, the control of large deformations and complex shapes has sometimes become the key goal of mechanism design, such as flexible robots, large-scale space deploy...
