Problems solved by technology

[0002] At present, the existing continuum actuators realize the bending deformation adjustment of each mechanical joint through the driving mechanism. However, when this adjustment method is subjected to external force, it is difficult for the continuum actuator to maintain the original deformation state, which leads to the continuum actuator The flexibility of the actuator is poor, which affects the performance of the continuum actuator

Abstract

The invention relates to the technical field of variable stiffness adjustment equipment, in particular to a continuum variable stiffness adjustment device. The continuum variable stiffness adjustment device includes a worm gear mechanism, a driving mechanism and two driving ropes, the worm gear mechanism includes a worm and two worm wheels, the driving mechanism is connected with the worm, and the worm is arranged on two Between the worm wheels, the two worm wheels are engaged with the worm respectively, and one end of the two driving ropes is respectively wound and connected with the power output ends of the two worm wheels, and one of the driving ropes is provided with Elastic elements. The invention can improve the ability of the continuum actuator to resist external force, achieve the effect of adjusting the stiffness, further improve the flexibility of the continuum actuator, and improve the performance of the continuum actuator.

Description

technical field [0001] The invention relates to the technical field of variable stiffness adjustment equipment, in particular to a continuum variable stiffness adjustment device. Background technique [0002] At present, the existing continuum actuators realize the bending deformation adjustment of each mechanical joint through the driving mechanism. However, when this adjustment method is subjected to external force, it is difficult for the continuum actuator to maintain the original deformation state, which leads to the continuum actuator The flexibility of the actuator is poor, which affects the performance of the continuum actuator. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] For this reason, the present invention proposes a continuum variable stiffness adjusting device, which can improve the ability of the continuum actuator to resist external force and achieve the p...
