Description

Technical Field

[0001] This utility model relates to the field of shock-absorbing shoe sole technology, specifically to a shock-absorbing shoe sole. Background Technology

[0002] Shoes are an essential part of daily life, protecting the feet. Shoes generally consist of an upper and a sole, with the sole protecting the foot during daily wear. In everyday life, shock absorption and cushioning are important indicators of sole comfort, especially for athletic shoes, where the heel area has the highest demand for shock absorption and cushioning.

[0003] For example, Chinese patent application number 202322810949.5 discloses a shoe sole with shock absorption and cushioning function, including a shoe sole body, a receiving cavity at the heel of the shoe sole body, a plurality of cushioning elements disposed in the receiving cavity, and a support plate nested in the receiving cavity; the cushioning elements include a cushioning body with a continuously zigzag cross-section, and a concave cushioning cavity disposed at one end of the cushioning body facing the receiving cavity, the inner wall of the cushioning cavity having a continuously zigzag cross-section, and a spring disposed in the cushioning cavity, one end of the spring supporting the bottom of the receiving cavity, and the other end supporting the cushioning cavity. The cavity bottom contains a cushioning pad, one side of which fits against the bottom of the cavity, and the other side fits against the support plate. A clearance hole runs through the cushioning pad corresponding to the position of the cushioning element, and the cushioning element is placed in the clearance hole. A protruding lower positioning ring is provided at the bottom of the cavity corresponding to the outer edge of the cushioning body. The end of the cushioning body away from the support plate is embedded in the lower positioning ring. A protruding upper positioning ring is provided on the support plate corresponding to the outer edge of the cushioning body. The end of the cushioning body closer to the support plate is embedded in the upper positioning ring. An exhaust hole runs through the bottom of the cushioning cavity. During shoe wearing, this technical solution utilizes the continuous zigzag cross-section of the cushioning body and the cushioning cavity to give the cushioning body elasticity, providing shock absorption and cushioning at the heel of the sole. With the assistance of a spring, the shock absorption and cushioning effect at the heel is improved. The cavity at the heel reduces the weight of the sole and improves comfort.

[0004] However, the following problems still exist in this technical solution: the technical solution can improve the shock absorption and cushioning effect at the heel with the help of springs, but the spring rebounds quickly, which can easily cause secondary impact on the feet and cause discomfort. Utility Model Content

[0005] The purpose of this invention is to provide a shock-absorbing shoe sole that can cushion the sole of the foot by setting a buffer layer and a buffer pad, thereby improving the comfort of the sole. In addition, the anti-slip layer makes the sole itself slip-resistant, enriching the functionality of this invention and solving the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing shoe sole, comprising a sole body, wherein the sole body has a cushioning layer inside for cushioning the sole of the foot, a cushioning pad inside the sole body, an absorbent layer on the cushioning pad, the sole body includes a waterproof layer, a puncture-resistant layer outside the waterproof layer, an abrasion-resistant layer outside the puncture-resistant layer, an anti-slip layer outside the abrasion-resistant layer, and a plurality of anti-slip grooves at the bottom of the anti-slip layer.

[0007] Preferably, the cushioning layer includes a cushioning frame disposed inside the sole body, the cushioning frame having multiple placement slots, each placement slot being filled with a filler, the cushioning frame and the cushioning pad being made of natural rubber, and the filler being made of foamed thermoplastic polyurethane elastomer, used to cushion the soles of people's feet.

[0008] Preferably, the waterproof layer is made of ethylene-vinyl acetate copolymer material, which can effectively prevent moisture penetration, thereby keeping the sole of the shoe dry.

[0009] Preferably, the puncture-resistant layer is made of aramid fiber and is used to provide safety protection for the soles of people's feet.

[0010] Preferably, the wear-resistant layer is made of polyurethane material, which can prevent wear.

[0011] Preferably, the anti-slip layer is made of hard rubber, which can provide good friction and play an anti-slip role.

[0012] Preferably, the adsorption layer is an activated carbon insole, which can quickly absorb sweat from the feet and keep them dry.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. The buffer frame and buffer pad in this utility model are both made of natural rubber. Natural rubber can not only deform quickly when subjected to force, but also gradually return to its original shape after the force is removed. This characteristic allows the rubber to effectively buffer the impact during the buffering process and avoid secondary impact caused by excessive elastic recovery.

[0015] 2. The filling material in this utility model is made of foamed thermoplastic polyurethane elastomer. Foamed thermoplastic polyurethane elastomer has the characteristics of high resilience and lightweight. It forms countless tiny closed air bubbles inside, which can absorb and release energy, providing excellent shock absorption and resilience performance. By setting a buffer layer and a buffer pad, it can cushion the soles of people's feet and improve the comfort of the shoe sole.

[0016] 3. The anti-slip layer in this utility model is made of hard rubber. Hard rubber is a polymer compound with high elasticity, high wear resistance and flexural strength. These properties enable it to provide good friction when in contact with the ground, thereby playing an anti-slip role. By setting the anti-slip layer, this utility model enables the sole body to have anti-slip properties, enriching the functionality of this utility model. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figure 1-6The cushioning sole shown includes a sole body 1, a cushioning layer 2 for cushioning the sole of the foot inside the sole body 1, a cushioning pad 3 inside the sole body 1, an absorbent layer 4 on the cushioning pad 3, a waterproof layer 101 outside the waterproof layer 101, a puncture-resistant layer 102 outside the puncture-resistant layer 102, an abrasion-resistant layer 103 outside the abrasion-resistant layer 103, and an anti-slip layer 104 outside the abrasion-resistant layer 103. The bottom of the anti-slip layer 104 has multiple anti-slip grooves 105.

[0030] like Figure 3 As shown, the buffer layer 2 includes a buffer frame 201 disposed inside the sole body 1. The buffer frame 201 has multiple placement slots 202, and each placement slot 202 is filled with a filler 203. The buffer frame 201 and the buffer pad 3 are both made of natural rubber, and the filler 203 is made of foamed thermoplastic polyurethane elastomer.

[0031] The natural rubber in this invention can not only deform quickly when subjected to force, but also gradually return to its original shape after the force is removed. This characteristic allows the rubber to effectively buffer the impact during the cushioning process and avoid secondary impact caused by excessive elastic recovery.

[0032] The foamed thermoplastic polyurethane elastomer of this invention has the characteristics of high resilience and lightweight. It has countless tiny closed bubbles inside, which can absorb and release energy, providing excellent shock absorption and resilience performance.

[0033] Because of the good cushioning performance of the sole body 1, it can reduce the pressure on the feet and reduce the impact on the user's knees, thus improving the comfort of the sole.

[0034] like Figure 4 As shown, the waterproof layer 101 is made of ethylene-vinyl acetate copolymer. The ethylene-vinyl acetate copolymer in this invention is a material with a closed-cell structure, which has good waterproof performance. This structure makes it non-absorbent and moisture-proof, effectively preventing the penetration of moisture, thereby keeping the sole body 1 dry.

[0035] like Figure 4 As shown, the puncture-resistant layer 102 is made of aramid fiber. The aramid fiber in this invention has excellent properties such as high tensile strength, low density, high elastic modulus and good thermal stability. When people step on sharp objects while walking, the excellent puncture-resistant properties of the puncture-resistant layer 102 can protect the soles of people's feet and improve the protective performance of the shoe sole body 1.

[0036] like Figure 4As shown, the wear-resistant layer 103 is made of polyurethane material. The polyurethane in this utility model has good wear resistance. By setting the wear-resistant layer 103, the sole body 1 can be worn for a long time without significant wear, and still maintain a good appearance and performance, thus extending the service life of this utility model.

[0037] like Figure 4 As shown, the anti-slip layer 104 is made of hard rubber. The hard rubber in this invention is a polymer compound with high elasticity, high wear resistance and flexural strength. These properties enable it to provide good friction when in contact with the ground, thereby playing an anti-slip role. By setting the anti-slip layer 104, this invention enables the sole body 1 to have anti-slip properties, enriching the functionality of this invention.

[0038] like Figure 4 As shown, the adsorption layer 4 is an activated carbon insole. The activated carbon in this invention has a complex porous structure and adsorbs odors and sweat through the physical attraction between molecules. The adsorption layer 4 is placed inside the sole body 1. In a humid environment or after a long period of exercise, the adsorption layer 4 adsorbs the sweat inside the sole body 1, thereby improving the wearer's comfort.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
