[0022] ​Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary 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 the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. In the drawings, for clarity, the thickness of regions and layers is exaggerated. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed descriptions will be omitted.

[0023] The described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a full understanding of embodiments of the present invention. However, those skilled in the art will recognize that the technical solutions of the present invention can be practiced without one or more of the specific details described, or other methods, components, materials, etc., can be employed. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring various aspects of the present invention.

[0024] The following example describes a cushioned shoe sole with an air cushion layer and an athletic shoe according to the present invention. This example is only a part of the embodiments of the present invention, but the protection scope of the present invention is not limited thereto. All other embodiments obtained by those skilled in the art without inventive effort should be covered within the protection scope of the present invention.

[0025] Please refer to the reference. Figures 1 to 3 As shown in the figure, according to an embodiment of the present invention, a cushioning shoe sole with an air cushion layer is provided, including a midsole assembly (not labeled in the figure) and an outsole 2 connected to the bottom side of the midsole assembly. The midsole assembly includes an EVA cushioning midsole 11 and a stress dispersion plate 12 located on the bottom side of the EVA cushioning midsole 11. An air cavity is formed in the stress dispersion plate 12 to form an air cushion layer (not labeled in the figure). The outsole 2 is connected to the bottom side of the stress dispersion plate 12, and the material stiffness of the stress dispersion plate 12 is greater than that of the EVA cushioning midsole 11. The outsole 2 is an EPR (ethylene propylene rubber) sheet, which gives the outsole 2 high wear resistance and anti-slip performance. The aforementioned EVA is specifically EVA foam material, which is a well-known cushioning material in the industry. Its scientific name is ethylene-vinyl acetate copolymer, which is a general polymer. The present invention only applies this well-known material and does not intend to improve or protect the composition of the material.

[0026] In this technical solution, on the one hand, by designing the sole as an EVA cushioning layer, a stress-dispersing cushioning layer, and a wear-resistant and anti-slip layer arranged in layers from top to bottom, the sole of this invention combines multiple properties such as cushioning, rebound, shock absorption, and wear resistance, meeting the needs of professional athletes for footwear and reducing or eliminating foot discomfort for athletes; on the other hand, this invention uses a low-stiffness EVA cushioning midsole 11 and a high-stiffness stress-dispersing plate 12 forming the air cushion layer, which can ensure the rebound force and cushioning effect of the sole while making the stress on the sole more even, preventing instability caused by excessive local deformation.

[0027] In some embodiments, the stress dispersion plate 12 is made of PEBAX (nylon elastomer). PEBAX is a commonly used elastomer in the industry. Its stiffness is greater than that of EVA foam material. It has the advantage of having a certain elasticity while ensuring small deformation, thereby ensuring the large-area dispersion and transmission of local stress. This utility model is only an adoption of PEBAX in the existing market and does not intend to protect its material composition.

[0028] See details Figure 1 As shown, in some embodiments, there is a concave-convex interlocking structure between the bottom surface of the stress-dispersing plate 12 and the top surface of the outsole 2. The concave-convex interlocking structure causes the stress-dispersing plate 12 at the top and the outsole 2 at the bottom to be interlocked in terms of material. This can improve the connection strength between the two and reduce the probability of the outsole 2 detaching from the stress-dispersing plate 12 due to adhesion defects between the two.

[0029] In some embodiments, the concave-convex embedding structure includes a first groove (not shown in the figure) on the bottom surface of the stress dispersion plate 12 and a convex strip (not shown in the figure) on the top surface of the outsole 2. The convex strip and the first groove both extend along the width direction of the cushioning sole to the left and right sides of the stress dispersion plate 12 and the outsole 2.

[0030] In this technical solution, the first groove is constructed on the stress dispersion plate 12 with high rigidity, which can reduce the deformation capacity of the stress dispersion plate 12 in the corresponding area to a certain extent. It is also worth noting that since the first groove runs through the width of the cushioning sole to the left and right sides, the deformation capacity of the sole following the up-and-down bending of the foot is improved, thereby improving the wearing comfort of the sole.

[0031] In another preferred embodiment, a second groove 21 is also constructed on the bottom side of the outsole 2. The second groove 21 is located in the area corresponding to the foot and the outsole 2, and the second groove 21 is located on each of the protrusions. In this technical solution, by further setting the second groove 21 at the location of the protrusions of the outsole 2, the deformation ability of the protrusions can be further improved, thereby ensuring that the outsole 2 has sufficient up-and-down bending ability while ensuring wear resistance and slip resistance, so that the wearing comfort of the sole is better.

[0032] In some embodiments, the outsole 2 has a through hole 22 in the area corresponding to the arch of the foot, which extends through the top and bottom surfaces. This design can reduce the amount of rubber used, thereby reducing material costs.

[0033] With the cushioning sole in its usable position as a reference, the front end of the EVA cushioning midsole 11 is connected to the front end of the outsole 2 and / or the rear end of the EVA cushioning midsole 11 is connected to the rear end of the outsole 2 to form a limiting effect on the front end and / or rear end of the stress dispersion plate 12, such as... Figure 1 As shown, the front end of the EVA cushioning midsole 11 and the front end of the outsole 2 are connected as one piece, which can limit the front end of the stress dispersion plate 12 located between the two. For example, Figure 3 As shown, the front end of the EVA cushioning midsole 11 and the front end of the outsole 2 are connected as one piece, and the rear end of the EVA cushioning midsole 11 and the rear end of the outsole 2 are also connected as one piece. This achieves simultaneous limiting of the front and rear ends of the stress dispersion plate 12 located between the two, thereby ensuring reliable limiting of the stress dispersion plate 12 and preventing the connection between the EVA cushioning midsole 11 and the stress dispersion plate 12, as well as the outsole 2 and the stress dispersion plate 12, from detaching due to bonding defects.

[0034] In some embodiments, there are multiple air chambers distributed in the foot and / or heel areas of the stress dispersion plate 12. Compared with a single air chamber structure, the structure of multiple air chambers can be set to correspond to the areas of the foot that are subjected to greater force, which can ensure the shock absorption effect while preventing the risk of instability that may occur if the air chamber setting area is too large.

[0035] In some embodiments, the EVA cushioning insole 11, stress dispersion plate 12, and outsole 2 are bonded together as a single unit. For example, polyurethane resin adhesive can be used to bond them together, resulting in a reliable connection and lower cost.

[0036] According to an embodiment of the present invention, a sports shoe is also provided, including the above-described shock-absorbing sole with an air cushion layer.

[0037] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
