[0038] Example

[0039] Please refer to Figure 1-4 As shown, this embodiment provides a sports shoe sole, including a midsole 1, an outsole 2, and an elastic plate 3. The midsole 1 includes an upper midsole 11 and a lower midsole 12. The elastic plate 3 is embedded between the upper midsole 11 and the lower midsole 12. The front end of the elastic plate 3 has an elastic arm 31 extending downward and backward. The elastic arm 31 passes around the front end of the lower midsole 12 and is fitted to the bottom surface of the lower midsole 12. The outsole 2 is fitted to the bottom surfaces of the lower midsole 12 and the elastic arm 31.

[0040] The elastic plate 3 is located between the upper midsole 11 and the lower midsole 12, improving the overall elasticity of the sole. It also features a downward-bending elastic arm 31, forming a "C"-shaped spring structure between the top and bottom surfaces of the lower midsole 12. When the sole is compressed, the elastic arm 31 is deformed. After the pressure is removed, it pushes the lower midsole 12 to rebound, causing the upper midsole 11 to apply a rebound force to the foot, further improving the overall elasticity of the sole. This avoids the need to change the material to improve the sole's elasticity, reduces production costs, and provides good durability, ensuring the sole maintains good elasticity.

[0041] Please refer to Figure 1 and Figure 3As shown, the front end of the lower midsole 12 has a clearance notch 121; the front end of the elastic plate 3 has a connecting section 35, which extends downward and connects to the elastic arm 31, fitting within the clearance notch 121. The connecting section 35 connects the elastic plate 3 and the elastic arm 31, and the clearance notch 121 accommodates the connecting section 35, preventing its end face from protruding from the midsole 1 and affecting the overall dimensions. A receiving groove (not shown in the attached diagram) is formed on the bottom surface of the lower midsole 12, and the elastic arm 31 is embedded in the receiving groove, flush with the bottom surface of the lower midsole 12. The receiving groove accommodates the elastic arm 31, preventing its end face from protruding from the bottom surface of the lower midsole 12 and affecting the flatness of the sole, and also limits the movement of the elastic arm 31, improving the accuracy of its action. A positioning protrusion (not shown in the attached diagram) is provided within the further receiving groove. A positioning channel 311 is provided on the elastic arm 31, and the positioning protrusion passes through the positioning channel 311. The bottom surface of the positioning protrusion is flush with the bottom surface of the lower middle base 12. The positioning protrusion is located in the middle of the elastic arm 31 to position the elastic arm 31, ensuring the accuracy of the installation position of the elastic arm 31, and further limiting the elastic arm 31 to improve the accuracy of the elastic arm 31's movement.

[0042] Please refer to Figure 3 As shown, the elastic plate 3 has a clearance opening 32 in the middle, and an elastic segment 33 is provided between the front and rear ends of the clearance opening 32. The elastic segment 33 bends downward. The top surface of the lower midsole 12 has an inner groove 122, and the elastic segment 33 fits into the inner groove 122. The ground surface of the upper midsole 11 has a pressing block 111, which presses against the top surface of the elastic segment 33. The elastic segment 33 is U-shaped. When the sole is subjected to pressure, the two ends of the elastic segment 33 bend downward under the pressure. After the downward pressure is removed, the two ends of the elastic segment 33 rebound, applying a force to the upper midsole 11 towards the foot, further improving the overall elasticity of the sole. The pressing block 111 and the inner groove 122 fit together on the top and bottom surfaces of the elastic segment 33 on both downward sides. During the pressing process, the inner groove 122 provides upward support for the elastic segment 33. During the rebound process, the elastic segment 33 directly applies a thrust to the pressing block 111, reducing energy loss.

[0043] The top surface of the lower bottom 12 is provided with an upwardly protruding positioning protrusion 123, which corresponds to the gap between the elastic segment 33 and the side wall of the clearance opening 32. The positioning protrusion 123 positions the elastic segment 33 on both sides, improving the accuracy of the installation position of the elastic plate 3. At the same time, it applies force to the elastic segment 33 on both sides to ensure that the elastic segment 33 bends and resets in the vertical direction, avoiding positional displacement of the elastic segment 33 during operation, which would affect the direction of the reaction force.

[0044] Please refer to Figure 1 and Figure 3 As shown, the bottom sides of the upper middle base 11 are provided with inwardly recessed mounting grooves 112, and the sidewalls of the clearance opening 32 are embedded in the mounting grooves 112. This further improves the accuracy of the installation position of the elastic plate 3, and the mounting grooves 112 limit the sidewalls of the clearance opening 32, maintaining the stability of both sides of the clearance opening 32 during the stress process, ensuring that the elastic segment 33 compresses and resets to its maximum stroke.

[0045] A fitting groove 124 is formed on the top surface of the lower insole 12, and the elastic plate 3 is embedded in the fitting groove 124. The fitting groove 124 lowers the installation height of the elastic plate 3, so that the end face of the elastic plate 3 is flush with the top surface of the lower insole 12, thereby ensuring a tight fit between the lower insole 12 and the upper insole 11; at the same time, it limits the edge of the elastic plate 3, improving the installation stability of the elastic plate 3. A limiting notch 34 is provided at the bottom end of the elastic plate 3, and a limiting protrusion 1241 is provided at the rear end of the fitting groove 124, which is embedded in the limiting notch 34. The limiting protrusion 1241 and the limiting notch 34 cooperate with each other to limit the installation position of the elastic plate 3, further improving the accuracy of the installation position of the elastic plate 3.

[0046] In this embodiment, the elastic plate 3 is a nylon glass fiber elastic plate 3, and the hardness of the elastic plate 3 is 84D. The nylon plate makes the overall weight of the sole lighter, reducing foot fatigue for athletes, and increases the glass limit by 15%, improving the overall hardness of the elastic plate 3 and ensuring that the elastic plate 3 applies sufficient rebound force to the foot.

[0047] Please refer to Figure 2 and Figure 3 As shown, the outsole 2 includes a main outsole 21 and a secondary outsole 22. The main outsole 21 is fitted to the front end of the bottom of the lower midsole 12. The rear end of the main outsole 21 has a rearward-extending extended outsole 211, located on the outside of the arch and extending to the rear end of the bottom surface of the lower midsole 12. The secondary outsole 22 is fitted to the rear end of the bottom surface of the lower midsole 12 and is positioned opposite the end of the extended outsole 211. The main outsole 21 covers the forefoot to ensure high friction for the foot during force application, improving the outsole's anti-slip performance. Since the contact between the arch and the ground is relatively small during exercise, the main outsole 21 covers the outside of the arch for anti-slip treatment of the main contact area, reducing production costs and the overall weight of the outsole. It also makes the arch area of ​​the outsole easier to bend, avoiding excessive force between the foot and the outsole, which could affect the force application. The main outsole 21 covers one side of the heel, and the secondary outsole 22 covers the other side of the heel, providing extensive coverage on both sides of the heel. This reduces the amount of material used in the outsole 2 while ensuring the anti-slip performance of the sole in the heel area, further lowering costs. In this embodiment, the bottom surfaces of the main outsole 21 and the secondary outsole 22 are provided with anti-slip patterns (not shown in the attached drawings).

[0048] In this embodiment, the outsole 2 is a CPU outsole 2, which ensures that the outsole 2 has better wear resistance, improves the service life of the shoe sole, and further reduces the weight of the shoe sole.

[0049] Please refer to Figure 5 As shown, this embodiment also discloses a sports shoe, including the above-mentioned sports shoe sole and upper 4, with the upper 4 connected to the top surface of the midsole 1.

[0050] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
