Description

Technical Field

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

[0002] Traditional shoe soles have shortcomings in shock absorption and breathability. For example, athletic or casual shoes typically rely on a single foam material (such as EVA or PU foam) for shock absorption. These materials are prone to aging after prolonged exposure to foot pressure, leading to a gradual decline in shock absorption and rebound performance. Simultaneously, poor breathability in the soles results in stuffy and damp feet, affecting comfort. While some breathable shoe designs exist, they often rely on simple ventilation holes, resulting in poor airflow circulation. Furthermore, the shock-absorbing and breathable structures are not tightly integrated, failing to achieve efficient shock absorption and breathability. Therefore, a sole structure that can simultaneously optimize both shock absorption and breathability is needed. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a circulating breathable and shock-absorbing shoe sole to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a circulating breathable and shock-absorbing shoe sole, comprising an outsole and a midsole disposed on top of the outsole, wherein the midsole is provided with an elastomer mounting groove located at the bottom of its heel area, and an air cavity is provided at the bottom of the elastomer mounting groove; an arch channel is provided at the bottom of the midsole in its arch area, and the arch channel communicates with the air cavity; the arch channel extends in the forefoot direction and connects to an arc-shaped air passage disposed at the bottom of the forefoot area of ​​the midsole, and the end of the air passage is connected to a tortuous channel; multiple ventilation holes penetrating to the top of the midsole are provided on the air passage and the tortuous channel; a protrusion is provided on the surface of the heel area of ​​the midsole, and a cylindrical groove is formed on the protrusion; a cylindrical pressure block protrudes upward from the bottom of the groove, and a gap is left between the pressure block and the inner wall of the groove; a fan-shaped heel protrusion is formed on the surface of the pressure block.

[0005] Furthermore, the heel protrusion includes a ring-shaped protrusion, and the side of the protrusion is provided with a plurality of fan blade-shaped support protrusions along the circumferential direction.

[0006] Furthermore, the outsole has a surrounding part at the forefoot position that surrounds the side of the forefoot, and the top of the surrounding part extends towards the heel to form an anti-kick section.

[0007] Furthermore, the bottom surface of the midsole is provided with multiple positioning grooves on both sides of the forefoot and heel areas, and one or more V-shaped forefoot positioning grooves are provided in the middle of the forefoot area. The bottom surface of the midsole arch area is provided with arch positioning grooves on both sides. The outsole surface is provided with positioning protrusions, forefoot positioning protrusions and arch positioning protrusions that fit into the positioning grooves, forefoot positioning grooves and arch positioning grooves.

[0008] Furthermore, the arch area of ​​the outsole has an upwardly convex arch structure, with its bottom and top surfaces being higher than the bottom and top surfaces of the forefoot and heel areas of the outsole; the arch area at the bottom of the midsole has a concave structure that fits into the arch structure.

[0009] Furthermore, the bottom of the outsole has multiple strip-shaped arch grooves on both sides of the arch area. The bottom of the arch grooves is provided with anti-slip blocks that protrude upwards, and the bottom surface of the anti-slip blocks protrudes from the bottom surface of the arch area of ​​the outsole.

[0010] Furthermore, the outsole has side anti-slip protrusions on both sides of the forefoot and heel areas, and the same number of edge anti-slip protrusions are provided on the inner side of the side anti-slip protrusions; the outsole has a front anti-slip protrusion at the front of the forefoot, a rear anti-slip protrusion at the rear of the heel, and center anti-slip protrusions at other positions on the forefoot and heel.

[0011] Furthermore, the surface of the outsole is provided with a groove array corresponding to the position of the anti-slip protrusion, and the outer contour of the groove array corresponds vertically to the contour of the corresponding anti-slip protrusion.

[0012] Furthermore, the midsole is made of highly elastic EVA or PU material, and the protrusions, pressure blocks, and heel protrusions are integrally injection molded with the midsole. Beneficial effects

[0013] Compared with the prior art, the present invention has at least the following advantages: 1. Utilizing the periodic pressing and releasing of the protrusions by the heel during walking, an automatic cycle of compression-exhaust-reset-intake is achieved. Upon landing, the air chamber is compressed, pushing air out of the forefoot ventilation holes into the shoe, blowing towards the forefoot and agitating the air inside. When lifting the foot, the air chamber resets, generating negative pressure, drawing air from inside the shoe into the sole through the forefoot ventilation holes, reserving air for the next exhaust cycle. This continuous and efficient autonomous ventilation, without relying on external power or conditions, fundamentally solves the problem of heat and moisture inside the shoe. The annular gap, during the negative pressure phase, enhances air intake efficiency by supporting the protrusions and improving heel comfort.

[0014] 2. By combining multiple levels of anti-slip protrusions, such as side anti-slip protrusions, edge anti-slip protrusions, front anti-slip protrusions, rear anti-slip protrusions, and center anti-slip protrusions, with an array of outsole grooves, the grip and anti-slip stability of the sole are improved on different surfaces.

[0015] 3. The air chamber absorbs impact during compression and reset, while elastic foam assists in shock absorption, achieving dual cushioning in the sole. This reduces foot injury from ground impact during walking, improves walking comfort, and avoids performance degradation caused by the aging of a single material. The arched design in the outsole's arch area provides natural arch support.

[0016] 4. The arch support, air passage, zigzag channel, elastomer mounting groove, air chamber, protrusion, sinker, pressure block, and heel protrusion are highly integrated into the midsole in one piece, with a compact structure and coordinated functions, realizing the combination of airflow circulation and cushioning process, achieving air exchange while absorbing shock.

[0017] 5. The positioning groove, forefoot positioning groove, arch positioning groove, positioning edge protrusion, forefoot positioning protrusion, and arch positioning protrusion fit together to prevent relative displacement between the outsole and midsole during use, thereby improving overall durability and stability.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] See Figures 1 to 5 This utility model provides a circulating breathable and shock-absorbing shoe sole, including an outsole 1 and a midsole 4. The outsole 1 is made of wear-resistant, high-friction rubber and is the part that directly contacts the ground. The midsole 4 is made of highly elastic EVA, PU or similar cushioning material and is located on top of the outsole 1.

[0028] The outsole 1 features an integrally molded surround 2 at the forefoot position, which surrounds the side of the forefoot to protect the toes. A kick-resistant section 3 extends from the top of the surround 2 towards the heel, enhancing the durability of the toe box. The arch area 30 of the outsole 1 has an upwardly convex arch structure, with its bottom and top surfaces higher than the bottom and top surfaces of the forefoot area 28 and heel area 29 of the outsole 1, providing stable support for the user's arch. The arch area at the bottom of the midsole has a recessed structure that fits and conforms to the arch structure of the outsole.

[0029] like Figure 4As shown, the bottom of the outsole 1 features a complex anti-slip pattern. Specifically, multiple side anti-slip protrusions 22 are provided on both sides of the forefoot area 28 and the heel area 29, and correspondingly, multiple edge anti-slip protrusions 23 are provided on their inner sides. A front anti-slip protrusion 21 is provided at the very front of the forefoot, and a rear anti-slip protrusion 27 is provided at the very back of the heel. Multiple center anti-slip protrusions 24 are provided at other locations on the forefoot and heel. Above each center anti-slip protrusion 24, a groove array 31 is provided on the surface of the outsole 1, which helps to reduce the weight of the outsole and increase local deformation capability to enhance grip. The outer contour of the groove array 31 corresponds vertically to the contour of the corresponding center anti-slip protrusion 24. Specifically, multiple strip-shaped arch grooves 25 are provided on both sides of the bottom of the arch area 30 of the outsole 1. Each arch groove 25 has an anti-slip block 26 protruding upward at its bottom. The bottom surface of the anti-slip block 26 is lower than the bottom surface of the arch area 30 of the outsole, so that it protrudes from the bottom surface of the arch area of ​​the outsole. This allows the protruding anti-slip block 26 to provide grip and prevent slippage when the arch part accidentally contacts the ground.

[0030] like Figure 2 As shown, at the bottom of the heel area 29 of the midsole, there is an elastomer mounting groove 10 for placing an additional elastomer, which is elastic foam, to help improve the shock absorption and rebound performance of the midsole. An air chamber 11 is provided at the bottom of the elastomer mounting groove, serving as an air storage and buffer chamber for cushioning. An arch channel 14 is provided at the bottom of the midsole in its arch area. The bottom surface of the arch channel 14 is lower than the bottom surface of the elastomer mounting groove 10. The arch channel 14 communicates with the air chamber 11 and extends towards the forefoot, connecting to an arc-shaped air passage 15 located at the bottom of the forefoot area of ​​the midsole. The air chamber 11 is connected to the arc-shaped air passage 15 through the arch channel 14. The end of the air passage 15 is connected to a U-shaped bend 16 to increase the airflow path length. Multiple ventilation holes 5 are evenly distributed at the top of the air passage 15 and the bend 16, penetrating to the upper surface of the midsole 4, forming ports for airflow into and out of the sole.

[0031] On the upper surface of the heel area 29 of the midsole 4, a protrusion 6 is integrally formed. Both the protrusion 6 and the air chamber 11 have an egg-shaped outer contour, and the position of the protrusion 6 corresponds vertically to the position of the air chamber. The protrusion 6 has a cylindrical groove 7 extending downwards, the depth of which is lower than the surface of the heel area of ​​the midsole. A cylindrical pressure block 8 protrudes upwards from the bottom of the groove 7, coaxial with the groove 7 and the pressure block 8, forming a ring-shaped gap between the periphery of the pressure block 8 and the inner wall of the groove 7. A fan-shaped heel protrusion 9, coaxial with the ring-shaped gap, is integrally formed on the top surface of the pressure block 8. The upper surface of the heel protrusion 9 is flush with the upper surface of the heel area of ​​the midsole 4 to prevent it from affecting foot fit and comfort. The heel protrusion 9 includes a ring-shaped protrusion 90 and multiple fan-blade-shaped support protrusions 91 evenly distributed circumferentially along the side of the ring 90. It should be noted that the air passage, zigzag passage, arch support, elastomer mounting groove, air chamber, protrusion, recess, pressure block, and fan-shaped heel protrusion are highly integrated into the midsole and molded as a single piece.

[0032] To ensure that the outsole 1 and midsole 4 do not shift during long-term use, a positioning structure is provided between them. Specifically, on the bottom surface of the midsole 4, multiple positioning grooves 12 are provided on both sides of the forefoot area 28 and the rearfoot area 29; two V-shaped forefoot positioning grooves 13 are provided in the middle of the forefoot area; and arch positioning grooves 19 are provided on both sides of the bottom surface of the arch area 30. Correspondingly, on the upper surface of the outsole 1, positioning protrusions 17, forefoot positioning protrusions 18, and arch positioning protrusions 20 are provided, which perfectly match the positioning grooves 12, forefoot positioning grooves 13, and arch positioning grooves 19. By interlocking the positioning grooves 12, forefoot positioning grooves 13, and arch positioning grooves 19 with the positioning protrusions 17, forefoot positioning protrusions 18, and arch positioning protrusions 20 respectively, and bonding them with adhesive, a firm and precise assembly of the outsole 1 and midsole 4 can be achieved.

[0033] The working principle is as follows: When the wearer walks and the heel strikes the ground, the heel presses against the fan-shaped heel protrusion 9 in the heel area of ​​the midsole 4, transmitting the pressure to the pressure block 8. The pressure block 8 moves downward, squeezing the air chamber downward, reducing its volume and increasing the internal air pressure. This propels the airflow forward, causing the air in the air chamber 11 to flow sequentially through the arch channel 14, air passage 15, and zigzag channel 16, finally exiting into the shoe cavity through the ventilation hole 5. This removes heat and moisture generated in the forefoot, while simultaneously promoting overall air circulation within the shoe. The compression of the air chamber 11 also serves as a cushioning effect.

[0034] At the same time, the downward movement of the pressure block reduces the volume of the annular gap, and the small amount of air in the gap is quickly squeezed outward, directly blowing away the humid and hot air accumulated in the heel, thus preventing the heel from sweating.

[0035] As the heel lifts to prepare for the next step, the foot releases pressure on the protrusion 6. The midsole, made of elastic material, exhibits excellent resilience. The protrusion 6, pressure block 8, and heel protrusion 9 return to their original position, and the air chamber 11 simultaneously returns to its original position, generating negative pressure. This negative pressure draws air from inside the shoe through the ventilation holes 5 into the zigzag channel 16, air passage 15, and arch channel 14, and into the air chamber 11, reserving air for the next downward pressure release. The annular gap expands and returns to its original position, creating localized negative pressure, causing air in the heel to flow towards the annular gap. During inhalation, the airflow passes through the radial channels between the protrusions, being divided into multiple airflows. These airflows collide and disturb each other, creating turbulence. This accelerates the intake speed of air into the annular gap and allows the humid air to initially mix with the surrounding fresh air, improving heat dissipation and moisture removal efficiency in the subsequent exhaust phase and ensuring auxiliary exhaust effect during the next downward pressure. This cycle repeats continuously, achieving automatic and continuous ventilation during walking.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
