Abstract
Description
Technical Field
[0001] This utility model relates to the field of footwear and apparel technology, specifically to a carbon fiber sole with a turbine structure. Background Technology
[0002] Shoes are items worn on the feet, primarily functioning to protect the feet, provide support, assist in walking or running, and adapt to the needs of different environments and occasions. They consist of a midsole, outsole, and upper. Most shoes also have a lacing system to flexibly adjust the fit of the upper around the foot. When wearing shoes, the foot enters between the midsole and upper through an opening at the heel. The upper covers the foot, allowing the shoe to move with it. The midsole, in conjunction with the upper, provides efficient cushioning, effectively protecting the foot and reducing fatigue and sports injuries. The sole is part of the shoe and typically includes a midsole and outsole. The midsole provides cushioning, while the outsole prevents the foot from slipping on the ground during movement.
[0003] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: While existing shoe soles can provide cushioning and support during foot movement, basketball is a complex sport where users often need to run, jump, change direction, and engage in contact. Therefore, the shoe sole is repeatedly subjected to forces in various directions. Existing shoe soles are prone to large-area deformation and torsion when subjected to lateral forces. Consequently, when performing actions such as sudden stops and changes of direction in basketball that generate large lateral forces on the shoe sole, the excessive torsional deformation of the shoe sole can easily lead to lateral rollover of the foot, resulting in poor stability. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a carbon plate shoe sole with a turbine structure that offers strong stability and good emergency stop support.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a carbon plate outsole with a turbine structure, comprising a midsole and an outsole fixed to the bottom surface of the midsole. The bottom surface of the midsole is provided with a turbine-stabilizing carbon plate at a corresponding position on the arch of the human foot. The turbine-stabilizing carbon plate includes a carbon plate body and a first upturned plate integrally formed on the carbon plate body at a corresponding position on the inner side of the arch of the human foot. A second upturned plate is integrally formed on the carbon plate body at a corresponding position on the outer side of the arch of the human foot. The first upturned plate and the second upturned plate are curved upward and extend along the midsole toward the heel of the human foot.
[0006] A further improvement is that the carbon plate body extends rearward to have a rear extension plate.
[0007] A further improvement is that the first upper flap plate has an integrally formed first upper protrusion groove that protrudes upwards.
[0008] A further improvement is that the second upper flap has an integrally formed second upper protrusion groove that bulges upward.
[0009] A further improvement is that the heel extension plate is integrally formed with an upwardly protruding third upper groove.
[0010] A further improvement is that a deformation groove is integrally formed on the side of the midsole at the end of the first upper flap.
[0011] A further improvement is that the outer side of the forefoot of the midsole also has an outsole upturn layer formed by the upturn of the outsole.
[0012] A further improvement is that the midsole also has a heel stabilizer block that surrounds the heel position of the midsole at the corresponding position of the human foot heel.
[0013] A further improvement is that the heel stabilizing block has several outwardly protruding reinforcing ribs integrally formed on it.
[0014] A further improvement is that the end of the heel stabilizer block also has an extended reinforcing piece that extends to the side of the midsole at the position corresponding to the arch of the human foot.
[0015] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When using this utility model, the upper is sewn onto the midsole for wearing. During wear, the foamed midsole provides strong cushioning, and the outsole provides high grip. At the same time, when performing basketball changes of direction, the midsole is subjected to lateral force output by the foot. The carbon plate body of the turbine-stabilized carbon plate has high hardness and supports the arch of the midsole, making the midsole more integrated and less prone to torsion. Meanwhile, the carbon plate body has a first and a second upturned plate on both sides of the arch of the human foot. The first upturned plate supports the arch, and the second upturned plate supports the outer side of the foot. When performing lateral push-off, the arch can maintain its curvature to prevent excessive collapse, maintain elasticity, and facilitate push-off. The second upturned plate supports the outer side of the midsole to maintain stability. Therefore, when performing explosive push-off, the force is smoother and more stable, and it is not prone to large-scale torsion, making it very suitable for basketball. Attached Figure Description

Figure 3 This is a top view structural schematic diagram of the turbine stabilizing carbon plate of this utility model. Detailed Implementation
[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0019] See Figure 1-3As shown, the technical solution adopted in this specific embodiment is: a carbon plate outsole with a turbine structure, including a midsole 1 and an outsole 5 fixed to the bottom surface of the midsole 1. A turbine-stabilizing carbon plate 6 is provided on the bottom surface of the midsole 1 at the corresponding position of the arch of the human foot. The turbine-stabilizing carbon plate 6 includes a carbon plate body 61 and a first upturned plate 63 integrally formed on the carbon plate body 61 at the corresponding position of the inner side of the arch of the human foot. A second upturned plate 62 is integrally formed on the carbon plate body 61 at the corresponding position of the outer side of the arch of the human foot. The first upturned plate 63 and the second upturned plate 62 are curved upward and extend along the midsole 1 towards the heel of the human foot. Specifically, the first upturned plate 63 and the second upturned plate 62 are respectively Extending upwards and backwards from the left and right edges of the carbon plate body 61 in an involute or vortex shape, the two are roughly parallel in the longitudinal direction, but the upward height and curvature can be adaptively designed according to the physiological structure of the foot. This "turbine"-shaped extension structure can better fit the inner and outer curves of the arch of the foot and effectively transfer and disperse lateral forces to the heel area. When in use, first sew the upper part of the shoe onto the midsole 1, and it can be worn. During wear, the foamed material midsole 1 provides strong cushioning, and the outsole 5 provides high grip, while making the sole more wear-resistant. Additional patterns can be added to the outsole 5 to further improve grip. When the wearer wears the shoes for basketball, the midsole 1 provides strong cushioning, and the outsole 5 provides high grip, while making the sole more wear-resistant. Additional patterns can be added to the outsole 5 to further improve grip. When the midsole 1 is stepped on, it can deform to absorb the reaction force of the ground on the human foot, thereby absorbing impact and providing cushioning. At the same time, it generates restorative elasticity to propel the foot, making running and jumping more comfortable and smooth. When the foot makes lateral push-off movements such as changing direction, the midsole 1 will be subjected to the lateral force output by the foot. The carbon plate body 61 of the turbine-stabilized carbon plate 6 has high rigidity and supports the arch of the midsole 1. This allows the force of the forefoot and heel to be transmitted and distributed on the forefoot and heel of the midsole 1 through the carbon plate body 61, making the midsole 1 more integrated and less prone to excessive torsion. This prevents ankle sprains caused by excessive torsion of the midsole during strong lateral push-offs. At the same time, the carbon plate body 61 is located on the human foot The foot arch is supported by a first upturned plate 63 and a second upturned plate 62 on both sides. The first upturned plate 63 supports the arch, and the second upturned plate 62 supports the outer side of the foot. When pushing off the ground laterally, the arch can maintain its curvature to prevent excessive collapse and maintain elasticity. This makes it easier to generate force when pushing off the ground and prevents sports injuries such as plantar fasciitis caused by excessive arch collapse. The second upturned plate 62 supports the outer side of the midsole 1 to maintain stability and prevent the midsole 1 from excessively deforming to the side and tilting. This makes it easier to generate force when pushing off the ground, and it is more stable and less prone to large-scale torsion. It is safe to wear and prevents sports injuries, making it very suitable for basketball. The carbon plate body 61 also extends rearward to have a heel extension plate 64. The heel extension plate 64 extends smoothly from the rear end of the carbon plate body 61, and its width may be slightly wider than the rear part of the carbon plate body 61, so as to increase the contact area with the heel area of the midsole 1. This is beneficial to expand the support area of the carbon plate body 61 through the heel extension plate 64, thereby improving the stability of the heel position of the midsole 1 when the heel lands.
[0020] The first upper flap 63 has an integrally formed first upper protrusion groove 65 that protrudes upward. The first upper protrusion groove 65 is a wing-shaped arc-shaped upward protrusion groove structure. The length direction of the first upper protrusion groove 65 is roughly consistent with the extension direction of the first upper flap 63. Its cross-section can be U-shaped or zigzag-shaped. By increasing the moment of inertia of the structural cross-section, the bending stiffness is improved. It is beneficial to improve the strength of the first upper flap 63 through the first upper protrusion groove 65, making it less prone to bending deformation when subjected to foot force, and further improving the support effect on the arch of the foot.
[0021] The second upper flap 62 has an integrally formed second upper protrusion groove 66 that protrudes upward. The second upper protrusion groove 66 is a wing-shaped arc-shaped upward protrusion groove structure. Its structural principle is similar to that of the first upper protrusion groove 65. It is set along the second upper flap 62 to enhance its resistance to lateral bending. It is beneficial to improve the strength of the second upper flap 62 through the second upper protrusion groove 66, so that it is less likely to deform and bend when subjected to lateral force generated by the lateral push of the foot. In this way, it can better restrict the middle section of the midsole 1 and prevent the phenomenon of rollover.
[0022] The heel extension plate 64 has an integrally formed third upper protrusion groove 67 that protrudes upward. The third upper protrusion groove 67 is an arc-shaped upper protrusion groove structure. The third upper protrusion groove 67 can be set in the middle of the heel extension plate 64 or at the position corresponding to the center pressure of the heel for local reinforcement. This is beneficial to improving the overall strength of the carbon plate body 61 and the heel extension plate 64, making it more resistant to bending and torsion, further improving the overall rigidity of the midsole 1, and preventing the midsole 1 from being excessively torsion when subjected to lateral force.
[0023] A deformation groove 4 is integrally formed on the side of the midsole 1 at the end of the first upper plate 63. The deformation groove 4 is a longitudinal groove formed on the side wall of the midsole 1, and its position is adjacent to the upper end of the first upper plate 63. When the arch of the foot is pressed down, the first upper plate 63 provides support, and the side wall area of the midsole 1 corresponding to its end can generate controllable deformation through the deformation groove 4, avoiding hard contact. It is beneficial to allow the midsole to collapse downward better when under force through the deformation groove 4, thereby improving the cushioning performance at this position and avoiding the discomfort of the first upper plate 63 pressing against the arch of the foot when wearing it, making it more suitable for people with low arches.
[0024] The forefoot outer side of the midsole 1 also has an outsole upturn layer 51 formed by the outsole 5. The outsole upturn layer 51 extends upward from the outer edge of the forefoot of the outsole 5 and partially wraps the sidewall of the midsole 1. Its height can cover a certain area of the side of the midsole 1 as needed. This is beneficial for wrapping the outer forefoot side of the midsole 1 with the outsole upturn layer 51, thus restricting its deformation. This not only improves the wear resistance of the outer forefoot side of the midsole 1, but also better maintains the stability of the midsole 1 when pushing off the ground laterally with the forefoot, preventing excessive deformation of the outer forefoot side of the midsole 1.
[0025] The midsole 1 also has a heel stabilizer 2 located at the corresponding position of the heel of the human foot. The heel stabilizer 2 is usually made of TPU (thermoplastic polyurethane) or rubber material with a hardness higher than that of the foam material of the midsole 1. It is fixed to the heel part of the midsole 1 by overmolding or bonding. After the foot is put on, the heel stabilizer 2 can wrap the heel of the foot and fix it, preventing it from slipping inside the shoe and causing instability. At the same time, it wraps and restricts the heel of the midsole 1. When the heel of the foot lands during a jump, if the heel position of the midsole 1 has a certain angle, it can also effectively limit the excessive tilting and deformation of the midsole 1 and prevent ankle sprains, thus effectively improving the anti-sprain performance.
[0026] The heel stabilizer 2 has several outwardly protruding reinforcing ribs 21 integrally formed. The reinforcing ribs 21 are horizontally extended and vertically arranged raised stripes. By increasing the local thickness of the material and the structural rigidity, deformation is reduced, which helps to further improve the strength of the heel stabilizer 2, so that it can better restrict the heel slippage of the foot and make the wearing stability and safety stronger.
[0027] The heel stabilizer block 2 also has an extension reinforcement plate 3 extending to the side of the midsole 1 at the corresponding position of the human foot arch. Its end is located in the foot arch area on the side of the midsole 1, and together with the outsole upturn layer 51 or the side wall of the midsole 1, it forms a lateral reinforcement frame for the middle section of the midsole 1. This is beneficial to further improve the deformation resistance and rollover resistance of the side of the midsole 1 through the extension reinforcement plate 3.
[0028] The turbine-stabilizing carbon plate 6 described in this invention (comprising a carbon plate body 61, a first upper flap 63, a second upper flap 62, a rear extension plate 64, and upper protrusions 65, 66, and 67) is preferably integrally molded from carbon fiber prepreg using a molding process. This process ensures seamless joints between components, a coherent overall structure, and excellent mechanical properties, guaranteeing its expected torsional resistance and support functions as a rigid component. Those skilled in the art can select different weaving methods, number of layers, and resin systems of carbon fiber prepregs based on the required stiffness and weight of the product, and process them using known molding temperature, pressure, and time parameters.
[0029] The working principle of this invention is as follows: When using this invention, the upper part of the shoe is first sewn onto the midsole 1, and then it can be worn. During wear, the foamed material midsole 1 provides strong cushioning, and the outsole 5 provides high grip, while also making the sole more wear-resistant. Additional treads can be added to the outsole 5 to further improve grip. When the wearer is playing basketball, the midsole 1 deforms to absorb the reaction force of the ground on the foot when stepped on, thus absorbing impact and providing cushioning. Simultaneously, it generates a restorative elasticity to propel the foot, making running and jumping more comfortable and smooth. When the foot makes lateral push-off movements such as changing direction, the midsole 1 receives the lateral force output by the foot. The carbon plate body 61 of the turbine-stabilized carbon plate 6 has high rigidity and supports the arch of the midsole 1, allowing the force from the forefoot and heel to be transmitted and distributed throughout the midsole 1 through the carbon plate body 61. The forefoot and heel countersole design enhance the overall integrity of the midsole 1, reducing the likelihood of excessive torsion and preventing ankle sprains caused by excessive midsole torsion during powerful lateral push-offs. Simultaneously, the carbon plate body 61 features a first upward-curving plate 63 and a second upward-curving plate 62 on either side of the arch of the foot. The first upward-curving plate 63 supports the arch, while the second upward-curving plate 62 supports the lateral side of the foot. During lateral push-offs, the arch maintains its curvature, preventing excessive collapse and preserving elasticity. This facilitates power generation during push-offs and prevents sports injuries such as plantar fasciitis caused by excessive arch collapse. Furthermore, the second upward-curving plate 62 supports the lateral side of the midsole 1, maintaining stability and preventing excessive lateral deformation and tipping. This results in smoother power generation during explosive push-offs, enhanced stability, reduced torsion, and high safety, making it ideal for basketball.
