Flexible hinge structure with directional energy conversion characteristics and parametric design method

Abstract

This invention relates to a flexible hinge structure with directional energy conversion characteristics and a parametric design method, comprising: at least one deformable structural unit, the deformable structural unit including a top beam, a bottom beam, and at least one inclined beam connecting the top beam and the bottom beam; wherein the top beam, bottom beam, and inclined beam enclose a structural cavity, and the central axis of the inclined beam is inclined relative to a local reference direction of the structure's location, so that when the deformable structural unit is subjected to vertical loads, the inclined beam undergoes coupled rotational and shear deformation, driving the deformable structural unit to generate displacement output along a predetermined direction. The beneficial effects of this invention are: this invention proposes a flexible hinge structure based on a pure geometric configuration, which can achieve controlled deformation and directional energy conversion under vertical loads without relying on additional rigid inserts.
