Description

Technical Field

[0001] This utility model relates to the field of shoe soles, and in particular to a novel shock-absorbing shoe sole. Background Technology

[0002] Shoes, as an indispensable part of daily life, originally served only to protect the feet from external environmental damage, ensuring safety while walking. With the rapid development of living standards, people's demands for shoes have increased, leading to the development of shoes with different functions, such as athletic shoes and hiking shoes.

[0003] In the past, most athletic shoes had soles made of synthetic polymer materials such as polyurethane (PU), thermoplastic styrene-butadiene rubber (TPR), and polyvinyl chloride (PVC). These soles are characterized by good wear resistance and easy processing. However, they do not provide much help in terms of athletic performance. When a person is exercising, the impact force of the foot hitting the ground can reach three times the body weight. How to protect the athlete's feet while cushioning such a huge impact has always been a key research and development focus for athletic shoe manufacturers.

[0004] Currently, most methods of cushioning shoes involve using elastic materials to make the soles. For example, the soles of most sports shoes are made of multi-layered bonded or single-layer solid structures made of materials such as EVA. In order to ensure their cushioning performance, the soles need to have a certain height. Therefore, such soles are not only heavy, but their cushioning effect is also limited.

[0005] Chinese Patent Application No. 201520451157.6 discloses a shock-absorbing shoe sole, including a sole body comprising a toe section, a midsection, and a heel section. The sole body includes an insole and an outsole. The top surface of the outsole has a groove, and the insole is installed in the groove. The top surface of the outsole and the bottom surface of the insole have locking blocks on the same vertical line, the locking blocks protruding from the top surface of the outsole and the bottom surface of the insole. A compression spring is installed between the two locking blocks. The bottom of the groove has a through groove that extends through the bottom surface of the outsole. A shock-absorbing bladder is installed in the through groove, protruding from both ends of the through groove opening. The shock-absorbing bladder is located in the midsection and heel section of the shoe. The groove wall has a guide groove that extends through the top surface of the outsole. The side wall of the insole has a guide block that fits with the guide groove with a clearance. The guide block is installed in the guide groove, allowing the insole to move up and down in the groove. The sole features a groove on the top surface of the outsole, within which a compression spring is installed. When the foot steps on the insole, the locking block compresses the shock-absorbing bladder within the groove, providing the first layer of shock absorption. When the compression force is greater, the compression spring is further compressed upon downward movement, providing the second layer of shock absorption, resulting in good shock absorption. However, during walking or exercise, the sole continuously expands and contracts, causing the compression spring within the sole to easily fatigue and fail, leading to poor durability and a decrease in shock absorption. Utility Model Content

[0006] Therefore, in view of the above problems, this utility model provides a new type of shock-absorbing shoe sole, which mainly solves the problem that the existing shock-absorbing shoe soles have poor durability and poor shock absorption effect after long-term use.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A novel shock-absorbing sole includes a sole body, defined as extending longitudinally along the length direction and laterally along the width direction. The sole body has a forefoot area, an arch area, and a heel area sequentially along the longitudinal direction. An mounting groove is recessed on the upper surface of the sole body at the arch and heel areas. A lower positioning groove extends through the bottom surface of the mounting groove, and side positioning grooves extend through the two lateral sides of the mounting groove. A shock-absorbing pad is embedded within the mounting groove. A lower positioning block, embedded in the lower positioning groove, extends from the lower surface of the shock-absorbing pad. Side positioning blocks, embedded in the side positioning grooves, extend from the two lateral sides of the shock-absorbing pad. The hardness of the shock-absorbing pad is less than that of the sole body. The shock-absorbing pad includes a group of shock-absorbing particles and a silicone sleeve covering the outside of the shock-absorbing particle group. The shock-absorbing particle group includes a plurality of thermoplastic polyurethane elastomer particles.

[0009] Furthermore, the upper surface of the sole body is provided with at least three first shock-absorbing grooves arranged in a row on both sides of the foot and arch areas.

[0010] Furthermore, the upper surface of the sole body is provided with at least three second shock-absorbing grooves located between two rows of first shock-absorbing grooves, and the second shock-absorbing grooves have a cylindrical hole structure.

[0011] Furthermore, a first protective block and a second anti-slip block are respectively protruding at both ends of the lower surface of the sole body, and at least three third anti-slip blocks are protruding on the lower surface of the sole body between the first anti-slip block and the second protective block. Drainage grooves are formed between the first anti-slip block and the third anti-slip block, between the second anti-slip block and the third anti-slip block, and between two adjacent third protective blocks.

[0012] Furthermore, the third anti-slip block includes at least two protrusions, and an auxiliary drainage channel communicating with the drainage channel is formed between two adjacent protrusions. The depth dimension of the auxiliary drainage channel is smaller than the depth dimension of the drainage channel.

[0013] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: This novel shock-absorbing sole, by recessing mounting grooves in the arch and heel areas on the upper surface of the sole body, embeds a shock-absorbing pad within the mounting grooves. The hardness of the shock-absorbing pad is less than that of the sole body, thereby achieving a shock-absorbing effect on the sole body. The shock-absorbing pad includes a shock-absorbing particle group and a silicone sleeve covering the outside of the shock-absorbing particle group. The shock-absorbing particle group includes a plurality of thermoplastic polyurethane elastomer particles, making the shock-absorbing pad a block-shaped material with good durability, providing long-term cushioning, reducing attenuation, and allowing the sole body to maintain a good shock-absorbing effect over a long period of use. At the same time, the protruding lower positioning block and side positioning block on the shock-absorbing pad are respectively fitted into the lower positioning groove and side positioning groove on the sole body, ensuring good installation firmness between the shock-absorbing pad and the sole body, improving product quality and the shock-absorbing performance of the sole, and enhancing the aesthetics of the sole body.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] The embodiment of this utility model is as follows:

[0020] refer to Figures 1 to 4As shown, a novel shock-absorbing shoe sole includes a sole body 1, defined as extending longitudinally along the length direction of the sole body 1 and laterally along the width direction of the sole body 1. The sole body 1 has a forefoot area 101, an arch area 102, and a heel area 103 sequentially along the longitudinal direction. An installation groove 2 is recessed on the upper surface of the sole body 1 at the arch area 102 and the heel area 103. A lower positioning groove 3 is provided through the bottom surface of the installation groove 2. Side positioning grooves 4 are provided through the two lateral sides of the installation groove 2. A shock-absorbing pad 5 is embedded in the installation groove 2. A lower positioning block 51 embedded in the lower positioning groove 3 extends from the lower surface of the shock-absorbing pad 5. Side positioning blocks 52 embedded in the side positioning grooves 4 extend from the two lateral sides of the shock-absorbing pad 5. The hardness of the shock-absorbing pad 5 is less than the hardness of the sole body 1. The shock-absorbing pad 5 includes a shock-absorbing particle group and a silicone sleeve covering the outside of the shock-absorbing particle group. The shock-absorbing particle group includes a plurality of thermoplastic polyurethane elastomer particles.

[0021] The specific method for preparing the shock-absorbing pad is as follows: First, prepare granular thermoplastic polyurethane elastomer particles, then fill the mold with the thermoplastic polyurethane elastomer particles, and finally inject silicone material into the mold to cover the thermoplastic polyurethane elastomer particles. After the rubber material cools, a silicone sleeve is formed, and the thermoplastic polyurethane elastomer particles and the silicone sleeve form a shock-absorbing pad.

[0022] This novel shock-absorbing sole features recessed mounting grooves 2 on the arch area 102 and heel area 103 of the sole body 1. A shock-absorbing pad 5 is embedded within these grooves, with the pad's hardness being less than that of the sole body 1. This design enhances the shock absorption effect of the sole body 1. The shock-absorbing pad 5 comprises a group of shock-absorbing particles and a silicone sleeve covering the outer side of these particles. The particle group consists of multiple thermoplastic polyurethane elastomer particles, forming a single, durable, and long-lasting cushioning effect, reducing attenuation and ensuring the sole body 1 maintains good shock absorption even after prolonged use. Furthermore, the lower positioning block 51 and side positioning block 52 protruding from the shock-absorbing pad 5 are respectively fitted into the lower positioning groove 3 and side positioning groove 4 on the sole body 1, ensuring a secure installation of the shock-absorbing pad 5 to the sole body 1. This improves product quality, the sole's shock absorption performance, and enhances the aesthetics of the sole body 1.

[0023] Furthermore, the upper surface of the sole body 1, located on both sides of the forefoot area 101 and the arch area 102, is provided with at least three first shock-absorbing grooves 6 arranged in a row. Preferably, the upper surface of the sole body 1, located on both sides of the forefoot area 101 and the arch area 102, is provided with six first shock-absorbing grooves 6 arranged in a row. The upper surface of the sole body 1, located between the two rows of first shock-absorbing grooves 6, is provided with at least three second shock-absorbing grooves 7. Preferably, the number of second shock-absorbing grooves 7 is eleven. The second shock-absorbing grooves 7 have a cylindrical hole structure, which further improves the shock absorption performance of the forefoot area 101 and the arch area 102 of the sole body 1.

[0024] In this embodiment, a first protective block 8 and a second anti-slip block 9 are respectively protruding from both ends of the lower surface of the sole body 1. At least three third anti-slip blocks 10 are protruding from the lower surface of the sole body 1 between the first anti-slip block 8 and the second protective block 9. Preferably, there are fourteen third anti-slip blocks 10. A drainage groove 11 is formed between the first anti-slip block 8 and the third anti-slip block 10, between the second anti-slip block 9 and the third anti-slip block 10, and between two adjacent third protective blocks 10. Each third anti-slip block 10 includes at least two protrusions 100. The number of protrusions 100 can be two or three, depending on actual needs. An auxiliary drainage groove 12 communicating with the drainage groove 11 is formed between two adjacent protrusions 100. The depth of the auxiliary drainage groove 12 is smaller than the depth of the drainage groove 11, which facilitates the fit of the user to the ground when walking, improves the protective effect of the sole body 1, and improves the drainage capacity.
