3D printed graded resilience structure and shoe sole using 3D printed graded resilience structure

Abstract

The invention discloses a 3D printed graded resilience structure and a shoe sole using the 3D printed graded resilience structure. The 3D printed graded resilience structure comprises surface meshes,a plurality of 3D printed graded resilience crystal lattice units, loop edges, bottom meshes and inclined support rods, wherein each graded resilience crystal lattice unit consists of a cushioning component and a cushioning resilience part; each cushioning component forms a plane stress structure by n vertical rods, n inclined pull rods and 4n inclined support rods (n is greater than or equal to 3); and each cushioning resilience part is of a single elastic vertical post structure. Based on the foot sole pressure distribution, a 3D printed secondary rebounding structure is applied to the shoesole; through twice cushioning, impact energy generated through sports doing can be sufficiently absorbed; in addition, strong resilience force can be provided; sportsmen of different sports events and different sports features are supported to complete skills; the sportsmen are protected from sports injury; and in addition, the graded resilience structure also has the functions of comfortable andbreathable performance, customization, light weight and the like.

Description

technical field [0001] The invention belongs to the technical field of sports shoes, and in particular relates to a 3D printed hierarchical rebound structure and a shoe sole using the structure. Background technique [0002] With the expansion and popularization of national sports and fitness, people's requirements for the quality and style update speed of sports shoes are also constantly improving. The production of traditional sports shoes belongs to a technology-intensive industrial chain, involving a variety of processes, and the process technology is complex, which directly leads to a long R&D and production cycle. Even for large sports shoe manufacturers, it takes 18 months to design and produce a pair of sports shoes. [0003] When people are in sports, the impact force on the soles of the feet at the moment of contact with the ground is several times that of the human body's own gravity, and the soles of the feet bear greater pressure on the feet, causing a series of...

Problems solved by technology

[0004] However, this kind of material cushioning sole, which relies on the elasticity of soft materials to achieve cushioning, is prone to problems such as collapse and deformation due to the passage of time, so that the cushioning effect gradually weakens; on the other hand, the stronger the cushioning performance of the sole, the better the rebound performance It will be weakened accordingly. In racing sports and other occasions that require soles to have high resilience, ordinary cushioning soles cannot be both "slow" and "bounce".
