Title:
COMPLIANT JOINT HAVING LARGE STROKE IN PLANAR COMPOSITE STRUCTURE SPACE
Document Type and Number:
WIPO Patent Application WO/2020/173096
Kind Code:
A1
Abstract:
A compliant joint that has a large stroke in a planar composite structure space, comprising a rectangular planar unit (1) used for implementing an out-of-plane torsion function and a fork-shaped planar unit (2) used for implementing an in-plane rotation function, wherein the fork-shaped planar unit (2) is a fork-like structure that has an included angle into which two flexible straight beam sheets (201) intersect, and the rectangular planar unit (1) and the fork-shaped planar unit (2) are connected in an external or embedded manner. The present joint overcomes the problems in which existing planar structure compliant joints may only be equivalent to a single-degree-of-freedom large-stroke low-motion pair and existing LEMs compliant mechanisms are equivalent to multi-degree-of-freedom compliant joints that have smaller overall strokes, and has the advantages of a simple structure, easy processing, easy analysis and calculation, equivalent large stroke space and multiple degrees of freedom flexibility, and so on.
