[0002] The research and development of the shock-absorbing and rebounding sole is to protect the runner's body and reduce the impact on the feet, knees and hips. At the same time, it can quickly recover after being squeezed by pressure during exercise, and transfer and recover the accumulated energy, helping the runner to complete the next action more easily.

[0003] At present, the traditional practice in the industry is mostly to use ordinary EVA material, change its hardness, and increase thickness to achieve the cushioning effect; the disadvantage of this approach is that when the EVA material is soft enough, it can bring good cushioning effect, but it lacks stability, is easy to deform after wearing, and has poor rebound; when the hardness of the EVA material is guaranteed, it can bring good shaping effect, but the cushioning and rebound effects are extremely poor, which greatly affects the comfort of wearing. Summary of the Invention

[0004] The shock-absorbing sole designed in the present invention and the sports shoes having the same can at least partially solve the above problems.

[0005] The purpose of the present utility model is to provide a shock-absorbing sole, comprising a midsole component and an outsole connected to the bottom side of the midsole component, the midsole component comprising a first EVA shock-absorbing midsole, a second EVA shock-absorbing midsole and a stress dispersion plate, the stress dispersion plate being clamped between the first EVA shock-absorbing midsole and the second EVA shock-absorbing midsole, and being connected to the first EVA shock-absorbing midsole and the second EVA shock-absorbing midsole as a whole, the stiffness of the stress dispersion plate being greater than that of the first EVA shock-absorbing midsole and the second EVA shock-absorbing midsole, and taking the orientation of the shock-absorbing sole in use as a reference, the first EVA shock-absorbing midsole is located on the upper part of the second EVA shock-absorbing midsole.

[0008] In some embodiments, the top side surface of the second EVA cushioning midsole has a first boss and a second boss protruding toward the side of the stress dispersion plate, and the first boss is accommodated in the first hollow groove and / or the second boss is accommodated in the second hollow groove.

[0009] In some embodiments, the middle area of ​​the bottom side of the stress dispersion plate has a positioning column extending toward one side of the second EVA cushioning midsole, and the second EVA cushioning midsole is formed with a first positioning hole passing through its top side and bottom side, and the positioning column is inserted into the first positioning hole.

[0010] In some embodiments, the positioning post is a hollow structure with an open top.

[0011] In some embodiments, the midsole component further includes a bow-shaped rebound member, and an upwardly arched upper arch area is formed at the arch area of ​​the bottom side of the second EVA cushioning midsole. The bow-shaped rebound member is connected to the upper arch area, and the top surface of the bow-shaped rebound member is in contact with the bottom side of the upper arch area.

[0020] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. In the figures, regions and layer thicknesses are exaggerated for clarity. Identical reference numerals in the figures denote identical or similar structures, and thus detailed descriptions thereof will be omitted.

[0021] The described features, structures or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present invention. However, those skilled in the art will appreciate that the technical solutions of the present invention may be practiced without one or more of the specific details, or other methods, components, materials, etc. may be employed. In other cases, well-known structures, materials or operations are not shown or described in detail to avoid obscuring various aspects of the present invention.

[0022] The following examples illustrate the shock-absorbing sole and sports shoes of the present invention. These examples are only a portion of the embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. All other embodiments obtained by persons of ordinary skill in the art without inventive effort are intended to fall within the scope of protection of the present invention.

[0023] Please refer to Figure 1According to an embodiment of the present invention, a shock-absorbing sole is provided, comprising a midsole assembly (not labeled in the figure) and an outsole 2 connected to the bottom side of the midsole assembly, wherein the midsole assembly comprises a first EVA shock-absorbing midsole 11, a second EVA shock-absorbing midsole 12, and a stress dispersion plate 13, wherein the stress dispersion plate 13 is clamped between the first EVA shock-absorbing midsole 11 and the second EVA shock-absorbing midsole 12 and is integrally connected to the first EVA shock-absorbing midsole 11 and the second EVA shock-absorbing midsole 12, and the stiffness of the stress dispersion plate 13 is large. In the first EVA cushioning midsole 11 and the second EVA cushioning midsole 12, with the orientation of the cushioning sole in use as a reference, the first EVA cushioning midsole 11 is located on the upper part of the second EVA cushioning midsole 12. It can be understood that the aforementioned EVA is specifically an EVA foam material, specifically a cushioning material well-known in the industry, its scientific name is ethylene-vinyl acetate copolymer, which is a general-purpose high molecular polymer. The present utility model only applies to the well-known material and does not intend to improve and protect the components of the material.

[0024] In this technical solution, a stress dispersion plate 13 with relatively large rigidity is clamped between the first EVA cushioning midsole 11 and the second EVA cushioning midsole 12 in the midsole assembly, so that the local force applied to the foot can be buffered and transmitted to the stress dispersion plate 13 via the first EVA cushioning midsole 11. Due to the large rigidity of the stress dispersion plate 13, the local force can be uniformly transmitted to the second EVA cushioning midsole 12 in the lower layer over a large area on the entire stress dispersion plate 13, so that the elastic deformation of the second EVA cushioning midsole 12 is relatively uniform, preventing the occurrence of instability caused by excessive local deformation. At the same time, it can be understood that due to the stress dispersion effect of the aforementioned stress dispersion plate 13, the overall thickness of the first EVA cushioning midsole 11 and the second EVA cushioning midsole can also be improved to a certain extent, which is conducive to improving the overall cushioning effect and resilience of the midsole assembly, while also having a higher shaping effect.

[0025] In a specific embodiment, the material of the stress dispersion plate 13 is PEBAX, which is also a commonly used elastomer in the industry. Its stiffness is greater than that of EVA foam material. It can have a certain elasticity while ensuring small deformation, thereby ensuring the advantage of large-area dispersion transmission of local stress. The present invention only adopts the existing PEBAX on the market and does not intend to protect its material components.

[0026] The outsole 2 is selected based on the wear-resistance and anti-slip properties. In a specific embodiment, the outsole 2 is an EPR rubber sheet.

[0027] As a preferred implementation method, the forefoot area of ​​the stress dispersion plate 13 has a first hollow groove 131 that runs through the top side and the bottom side thereof. This can, on the one hand, reduce the overall mass of the stress dispersion plate 13, thereby reducing the overall weight of the entire sole; on the other hand, it can enhance the deformation ability of the forefoot area of ​​the stress dispersion plate 13, that is, enhance its bending flexibility, and enhance the overall wearing comfort of the sole; the heel area of ​​the stress dispersion plate 13 has a second hollow groove 132 that runs through the top side and the bottom side thereof. This can, on the one hand, reduce the overall mass of the stress dispersion plate 13, thereby reducing the overall weight of the entire sole; on the other hand, it can enhance the comfort of the user's heel position.

[0028] As another preferred embodiment, the top side surface of the second EVA cushioning midsole 12 has a first boss (not shown in the figure) and a second boss (not shown in the figure) protruding toward the side of the stress dispersion plate 13, and the first boss is accommodated in the first hollow groove 131 and / or the second boss is accommodated in the second hollow groove 132. Preferably, the first boss and the second boss are respectively matched one by one with the shapes of the first hollow groove 131 and the second hollow groove 132, so that the sole has a more fitting support and load-bearing plane, further improving the user's comfort.

[0029] In some embodiments, the middle area of ​​the bottom side of the stress dispersion plate 13 has a positioning column 133 extending toward the side of the second EVA cushioning midsole 12, and the second EVA cushioning midsole 12 is formed with a first positioning hole 121 passing through the top side and the bottom side thereof, and the positioning column 133 is inserted into the first positioning hole 121.

[0030] In this technical solution, the aforementioned positioning column 133 and the first positioning hole 121 are inserted as one body, which can improve the position stability between the stress dispersion plate 13 and the second EVA cushioning midsole 12, and prevent the displacement deviation between the two from being too large during use, resulting in cracking and other damage.

[0031] In some embodiments, the positioning column 133 is a hollow structure with an open top, which can further reduce the overall mass of the stress dispersion plate 13 .

[0032] In some embodiments, the midsole assembly further includes a bow-shaped rebound member 14, and an upwardly arched upper arch area (not labeled in the figure) is formed in the arch area of ​​the bottom side of the second EVA cushioning midsole 12. The bow-shaped rebound member 14 is connected to the upper arch area, and the top surface of the bow-shaped rebound member 14 is in contact with the bottom side of the upper arch area. By arranging the bow-shaped rebound member 14 in the aforementioned upper arch area, the rebound performance of the sole can be further improved.

[0033] A second positioning hole 141 is formed on the bow-shaped resilient member 14, and a positioning protrusion (not marked in the figure) is provided on the bottom end surface of the positioning column 133 and is inserted into the second positioning hole 141. In this way, through the insertion and positioning between the arc positioning protrusion and the second positioning hole 141, the bow-shaped resilient member 14 forms a positioning and support for the bottom end of the aforementioned positioning column 133, ensuring a more reliable connection between the various components while further improving the force transmission and rebound performance.

[0034] In some embodiments, adjacent components among the first EVA cushioning midsole 11, the second EVA cushioning midsole 12, the stress dispersion plate 13, the outsole 2, and the bow-shaped rebound member 14 are bonded together, for example, by using polyurethane resin glue, which has reliable connection and low cost.

[0035] During actual use, the force of the foot pressing is transmitted through the shock absorption of the upper midsole (i.e. the aforementioned first EVA cushioning midsole 11) to the PEBAX material (i.e. the aforementioned stress dispersion plate 13), diffused and decomposed, and then transmitted to the middle midsole (i.e. the aforementioned second EVA cushioning midsole 12) for shock absorption, and then transmitted to the bottom midsole (i.e. the aforementioned bow-shaped rebound component 14), and then transmitted to the ground through the arc structure of the bottom midsole for shock absorption, and then the force can be rebounded through the reaction force.

[0036] The utility model also provides a sports shoe comprising the above-mentioned shock-absorbing sole.

[0037] It is easy for those skilled in the art to understand that, under the premise of no conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0038] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
