SUMMARY

[0003] In view of the deficiencies of the prior art, the utility model aims to provide a sole with shock-absorbing hollow layer and shoe to solve the problem that the existing sole shock-absorbing technology mainly embeds various shock-absorbing structures in the insole or relies on shock-absorbing materials to achieve the effect of shock absorption. However, due to the large self-weight of the adopted structure, the midsole is very thick, although the shock-absorbing effect is guaranteed, the lightness and flexibility of the shoe are sacrificed to a certain extent, and the material shock absorption also has attenuation, the elasticity of the material gradually decreases with the increase of the number of uses and the passage of time, the shock-absorbing effect is greatly discounted, the durability is not strong, and reliable shock-absorbing protection cannot be provided for runners for a long time.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a sole with shock-absorbing hollow layer, comprising a sole body, a shock-absorbing unit is arranged at the heel of the sole body, the shock-absorbing unit comprises a midsole support body at the upper part, the midsole support body is provided with a surrounding part on both sides, the midsole support body is provided with an elastic support wall curled vertically downward on both sides, the lower end of the elastic support wall is provided with a shock-absorbing framework, the center of the shock-absorbing framework is an arc-shaped pressure receiving piece, the arc-shaped pressure receiving piece is provided with a support pressure distribution piece on both sides, and the bottom of the shock-absorbing framework is provided with a buffer pad.

[0005] The surrounding part is arranged on the outer edge of the sole body, the lower end of the elastic support wall is connected to the support pressure distribution piece, and the midsole support body, the elastic support wall and the shock-absorbing framework form a compression cavity inside.

[0006] Furthermore, the midsole support body is integrally formed with the sole body, and the midsole support body has a sheet-like structure.

[0007] Furthermore, the compression chamber is filled with shock-absorbing foam.

[0008] Furthermore, an arc-shaped groove is formed at the bottom of the arc-shaped pressure plate, and a pressure-bearing strip is embedded in the arc-shaped groove.

[0009] Furthermore, the bottom of the pressure-bearing strip is provided with several shock-absorbing columns.

[0010] Furthermore, the bottom surface of the sole body is provided with an anti-slip plate, which is X-shaped.

[0011] Furthermore, the cushioning pad is arranged around the outer contour of the heel of the sole body, and the shape of the cushioning pad is a concave shape that expands from the center to the surrounding area.

[0012] Furthermore, the elastic support wall is either rolled or arc-shaped.

[0015] The beneficial effects of this invention are as follows: When in use, the heel first contacts the ground, at which point the entire shock-absorbing unit is compressed by the impact force. The impact force from the heel is first borne by the midsole support and then transmitted to the elastic support arm. As the elastic support arm curls and folds, the compression chamber begins to compress. The cushioning foam filled in the compression chamber fully absorbs the impact force.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Example 1

[0025] Please see Figure 1 , Figure 2 This utility model provides a shoe sole technology solution with a shock-absorbing hollow layer:

[0026] A shoe sole with a shock-absorbing hollow layer includes a shoe sole body 1. A shock-absorbing unit 2 is provided at the heel of the shoe sole body 1. The shock-absorbing unit 2 includes an upper midsole support body 21. The midsole support body 21 has a surrounding part 22 on both sides. The midsole support body 21 has vertically downward curled elastic support walls 23 on both sides. The lower end of the elastic support wall 23 has a shock-absorbing skeleton 24. The center of the shock-absorbing skeleton 24 is an arc-shaped pressure plate 241. The arc-shaped pressure plate 241 has supporting pressure plates 242 on both sides. The bottom of the shock-absorbing skeleton 24 has a cushioning pad 26.

[0027] The surrounding part 22 is arranged around the outer edge of the sole body 1, the lower end of the elastic support wall 23 is connected to the support pressure plate 242, and the midsole support body 21, the elastic support wall 23 and the shock-absorbing skeleton 24 form a compression cavity 25. The entire shock-absorbing unit 2 forms a compression cavity. When subjected to the impact force of the foot, the entire shock-absorbing unit 2 is compressed, thereby providing better cushioning effect and longer durability.

[0028] Reference Figure 1 In this embodiment, to facilitate the production of the shoe sole, the midsole support 21 is integrally formed with the shoe sole body 1, and the midsole support 21 has a sheet-like structure, which simplifies the production process and saves costs.

[0029] Reference Figure 2 , Figure 3In this embodiment, in order to increase the comfort of the shoe, the compression cavity 25 is filled with shock-absorbing foam. The shock-absorbing foam can effectively absorb impact and increase the comfort and shock absorption of the shoe while maintaining the shock absorption stability and responsiveness of the shock absorption unit 2 structure.

[0030] Reference Figure 2 , Figure 3 In this embodiment, in order to protect the shock-absorbing frame 24, an arc-shaped groove 243 is formed at the bottom of the arc-shaped pressure plate 241. A pressure-bearing strip 244 is embedded in the arc-shaped groove 243 to prevent the shock-absorbing frame 24 from directly contacting the ground and increase durability. The pressure-bearing strip 244 absorbs and alleviates the impact from the ground while bearing the pressure from the foot.

[0031] Reference Figure 4 To better absorb the impact force from the ground, the bottom of the pressure-bearing strip 244 is provided with several shock-absorbing columns 245. In this embodiment, the elastic deformation of multiple shock-absorbing columns 245 is used to disperse and buffer the impact force from the ground. When the shoe contacts the ground, the impact force first acts on the shock-absorbing columns 245. The shock-absorbing columns 245 undergo compression deformation due to the force, converting kinetic energy into elastic potential energy, thereby effectively reducing the impact force on the feet and body. At the same time, in this embodiment, in order to increase the grip of the sole during exercise, the bottom surface of the sole body 1 is provided with an anti-slip plate 11. The anti-slip plate 11 is X-shaped. Designing the anti-slip plate 11 in an X-shape increases the anti-slip performance of the sole in both the forward and lateral directions.

[0032] Reference Figure 4 During running, the heel is the area that experiences the greatest force. In this embodiment, the cushioning pad 26 is arranged around the outer contour of the heel of the sole body 1. The surrounding cushioning pad can more effectively absorb the impact force from the ground. In order to further improve the shock absorption performance, the cushioning pad 26 is concave in shape, expanding from the center to the surrounding area. The concave cushioning pad 26 provides a working mode like a shock absorber, while keeping the heel centered. Because the concave sole expands outward, it disperses the impact force to the outside rather than upward to the athlete's foot. When the cushioning pad 26 contacts the ground, it expands outward, first compressing at the outer edge to cushion the foot, reducing the transmission of impact to the leg and providing a wider support base, thereby protecting the foot, leg and knee.

[0033] Reference Figure 6 In this embodiment, the elastic support wall 23 is specifically rolled up. When the elastic support arm 23 is rolled up and folded, it is similar to the compression method of an accordion, which effectively compresses the entire shock absorption unit 2, thereby providing better cushioning effect and longer durability.

[0034] Reference Figure 2To improve the durability of the sole, the elastic support wall 23 and the shock-absorbing frame 24 are made of hydrogenated nitrile rubber, a special elastomer made by nitrile rubber (NBR) through a catalytic hydrogenation reaction. The elastic support arm 23 made of this material has a longer-lasting durability while ensuring rebound and shock absorption performance.

[0035] Reference Figure 6 This embodiment provides a shoe made of the aforementioned sole body 1, and also includes an upper 3. The bottom of the upper 3 is located on the top of the sole body 1. The upper 3 and the sole body 1 are fixed together by a heat-pressing bonding method. When running, the heel first contacts the ground. At this time, the entire shock-absorbing unit 2 is compressed by the impact force. The impact force brought by the heel is first borne by the midsole support 21, and then transmitted to the elastic support arm 23. While the elastic support arm 23 is curled and folded, the compression cavity 25 begins to compress. The cushioning foam filled in the compression cavity 25 fully absorbs the impact force. Then the impact force is transmitted to the shock-absorbing frame 24, and finally to the cushioning pad 26 of the sole.

[0036] Example 2

[0037] Please see Figure 1 , Figure 2 This utility model provides a shoe sole technology solution with a shock-absorbing hollow layer:

[0038] A shoe sole with a shock-absorbing hollow layer includes a shoe sole body 1. A shock-absorbing unit 2 is provided at the heel of the shoe sole body 1. The shock-absorbing unit 2 includes an upper midsole support body 21. The midsole support body 21 has a surrounding part 22 on both sides. The midsole support body 21 has vertically downward curled elastic support walls 23 on both sides. The lower end of the elastic support wall 23 has a shock-absorbing skeleton 24. The center of the shock-absorbing skeleton 24 is an arc-shaped pressure plate 241. The arc-shaped pressure plate 241 has supporting pressure plates 242 on both sides. The bottom of the shock-absorbing skeleton 24 has a cushioning pad 26.

[0039] The surrounding part 22 is arranged around the outer edge of the sole body 1, the lower end of the elastic support wall 23 is connected to the support pressure plate 242, and the midsole support body 21, the elastic support wall 23 and the shock-absorbing skeleton 24 form a compression cavity 25. The entire shock-absorbing unit 2 forms a compression cavity. When subjected to the impact force of the foot, the entire shock-absorbing unit 2 is compressed, thereby providing better cushioning effect and longer durability.

[0040] Reference Figure 1 In this embodiment, to facilitate the production of the shoe sole, the midsole support 21 is integrally formed with the shoe sole body 1, and the midsole support 21 has a sheet-like structure, which simplifies the production process and saves costs.

[0041] ReferenceFigure 2 , Figure 3 In this embodiment, in order to increase the comfort of the shoe, the compression cavity 25 is filled with shock-absorbing foam. The shock-absorbing foam can effectively absorb impact and increase the comfort and shock absorption of the shoe while maintaining the shock absorption stability and responsiveness of the shock absorption unit 2 structure.

[0042] Reference Figure 2 , Figure 3 In this embodiment, in order to protect the shock-absorbing frame 24, an arc-shaped groove 243 is formed at the bottom of the arc-shaped pressure plate 241. A pressure-bearing strip 244 is embedded in the arc-shaped groove 243 to prevent the shock-absorbing frame 24 from directly contacting the ground and increase durability. The pressure-bearing strip 244 absorbs and alleviates the impact from the ground while bearing the pressure from the foot.

[0043] Reference Figure 4 To better absorb the impact force from the ground, the bottom of the pressure-bearing strip 244 is provided with several shock-absorbing columns 245. In this embodiment, the elastic deformation of multiple shock-absorbing columns 245 is used to disperse and buffer the impact force from the ground. When the shoe contacts the ground, the impact force first acts on the shock-absorbing columns 245. The shock-absorbing columns 245 undergo compression deformation due to the force, converting kinetic energy into elastic potential energy, thereby effectively reducing the impact force on the feet and body. At the same time, in this embodiment, in order to increase the grip of the sole during exercise, the bottom surface of the sole body 1 is provided with an anti-slip plate 11. The anti-slip plate 11 is X-shaped. Designing the anti-slip plate 11 in an X-shape increases the anti-slip performance of the sole in both the forward and lateral directions.

[0044] Reference Figure 4 During running, the heel is the area that experiences the greatest force. In this embodiment, the cushioning pad 26 is arranged around the outer contour of the heel of the sole body 1. The surrounding cushioning pad can more effectively absorb the impact force from the ground. In order to further improve the shock absorption performance, the cushioning pad 26 is concave in shape, expanding from the center to the surrounding area. The concave cushioning pad 26 provides a working mode like a shock absorber, while keeping the heel centered. Because the concave sole expands outward, it disperses the impact force to the outside rather than upward to the athlete's foot. When the cushioning pad 26 contacts the ground, it expands outward, first compressing at the outer edge to cushion the foot, reducing the transmission of impact to the leg and providing a wider support base, thereby protecting the foot, leg and knee.

[0045] Reference Figure 6In this embodiment, the elastic support wall 23 is specifically arc-shaped. When subjected to external impact, the arc-shaped elastic support wall 23 can flexibly change its curvature according to the direction and magnitude of the force, similar to how an arch bridge structure cleverly disperses pressure when bearing heavy objects, distributing the impact force evenly to the entire support wall surface, avoiding material damage caused by local stress concentration, and thus effectively extending the service life of the entire shock absorption unit 2.

[0046] Reference Figure 2 To improve the durability of the sole, the elastic support wall 23 and the shock-absorbing frame 24 are made of hydrogenated nitrile rubber, a special elastomer made by nitrile rubber (NBR) through a catalytic hydrogenation reaction. The elastic support arm 23 made of this material has a longer-lasting durability while ensuring rebound and shock absorption performance.

[0047] Reference Figure 6 This embodiment provides a shoe made of the aforementioned sole body 1, and also includes an upper 3. The bottom of the upper 3 is located on the top of the sole body 1. The upper 3 and the sole body 1 are fixed together by a heat-pressing bonding method. When running, the heel first contacts the ground. At this time, the entire shock-absorbing unit 2 is compressed by the impact force. The impact force brought by the heel is first borne by the midsole support 21, and then transmitted to the elastic support arm 23. While the elastic support arm 23 is curled and folded, the compression cavity 25 begins to compress. The cushioning foam filled in the compression cavity 25 fully absorbs the impact force. Then the impact force is transmitted to the shock-absorbing frame 24, and finally to the cushioning pad 26 of the sole.

[0048] During use, the heel first contacts the ground, at which point the shock-absorbing unit 2 begins to function. The impact force from the heel is first absorbed by the midsole support 21 and then transmitted to the elastic support arm 23. As the elastic support arm 23 curls and folds, the compression chamber 25 begins to compress. The cushioning foam filled in the compression chamber 25 fully absorbs the impact force. Next, the impact force is transmitted to the shock-absorbing frame 24. The arc-shaped pressure plate 241 in the shock-absorbing frame 24 is compressed by the cushioning foam, providing support to counteract the impact force. The support pressure-distributing plates 242 on both sides of the arc-shaped pressure plate 241 then begin to disperse the impact force. Finally, the impact force... The impact force is transmitted to the cushioning pad 26, which expands outward when subjected to impact. It first compresses at the periphery to disperse the impact force to the outside, providing a wider support base and cushioning surface to cushion the foot. At the same time, multiple shock-absorbing columns 245 on the pressure-bearing strip 244 form multiple cushioning points. When the shoe contacts the ground, the impact force first acts on the shock-absorbing columns 245. The shock-absorbing columns 245 are compressed and deformed due to the force, converting kinetic energy into elastic potential energy, thereby effectively reducing the impact force on the foot and body. Multiple shock-absorbing columns 245 work together to distribute the impact force more evenly, avoid excessive local pressure, and improve the overall shock absorption effect and stability.
