Abstract
Description
Technical Field
[0001] This utility model relates to the field of EVA midsole technology, specifically a high-elasticity, shock-absorbing EVA midsole structure. Background Technology
[0002] Shoes are mainly composed of an upper and a sole. The comfort of a shoe depends primarily on the midsole, which is the part of the shoe that directly contacts the ground. It is directly subjected to the friction and impact of the ground and transmits the reaction force of the ground to the foot. For sports shoes, the midsole especially needs to have sufficient shock absorption to avoid injuries caused by the impact of sports, thereby achieving the purpose of training or competition. People hope that their feet can be effectively protected during sports and that exercise fatigue can be reduced. However, the cushioning and shock absorption function of sports shoes still needs to be strengthened and improved.
[0003] Therefore, it is particularly important to design a highly elastic and shock-absorbing EVA midsole structure to overcome the above-mentioned technical defects and improve overall practicality. Utility Model Content
[0004] The purpose of this invention is to provide a highly elastic and shock-absorbing EVA midsole structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A high-elasticity, shock-absorbing EVA midsole structure includes a shoe midsole, with a cushioning pad embedded in the top of the midsole. An elastic protrusion is provided on the top of the cushioning pad, and multiple sets of evenly distributed hollow shells are embedded in the top of the elastic protrusion. A solid shell seat is connected to the bottom of the hollow shell, and a central shell column is fixed at the middle position inside the hollow shell. The interior of the hollow shell is filled with cushioning beads.
[0007] As a preferred embodiment of this utility model, the cushioning pad is made of EVA material and is embedded in the top surface of the shoe midsole by stitching.
[0008] As a preferred embodiment of this utility model, the elastic boss is connected to the top of the buffer pad by adhesive bonding, and the elastic boss is made of high-elastic rubber material.
[0009] As a preferred embodiment of this utility model, the top of the elastic boss is provided with multiple sets of grooves corresponding to the positions of the hollow bladder, and the solid bladder seat is glued to the inside of the grooves by means of adhesive bonding.
[0010] As a preferred embodiment of this utility model, the hollow shell, solid base, central column, and buffer beads are all made of transparent buffer PVC material.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] In this invention, a high-elasticity, shock-absorbing EVA midsole structure is designed. An EVA cushioning pad is added inside the midsole, and a layer of high-elasticity rubber protrusions is placed on top of the cushioning pad. These protrusions, through their ability to deform under pressure and their excellent rebound performance, give the midsole a good energy return value, providing a support effect. Simultaneously, multiple evenly distributed hollow shells are embedded on the top surface of the elastic protrusions. The bottom of each hollow shell is connected to a solid shell base, and a central column is connected to the middle of the hollow shell. The remaining portion is filled with cushioning beads. This structure, composed of fixed and flowing cushioning PVC material, achieves both shock absorption and support. This multi-group design disperses the impact force generated during exercise, reduces joint impact, and improves athletic performance and comfort. Attached Figure Description
