Abstract
Description
Technical Field
[0001] This utility model relates to the field of footwear and apparel technology, specifically to a drop crystal carbon fiber cloth stabilizing sheet and sports shoes with the stabilizing sheet. Background Technology
[0002] Stabilizer plates are key components for improving the torsional rigidity, support, and stability of a shoe. The heel stabilizer plate in athletic shoes is a special structural component embedded in the heel area of the midsole. It is mainly used to limit excessive movement or deformation of the heel during exercise, improving stability, support, and torsional rigidity upon landing, thereby reducing the risk of injury and optimizing athletic performance. Carbon fiber fabric is a woven fabric that can produce a reflective effect and is often sewn onto the upper of athletic shoes. When wearing athletic shoes for nighttime exercise, the reflectivity of the carbon fiber fabric can cause headlights from vehicles to reflect off the wearer, making it easier to identify the wearer's position and making nighttime exercise safer.
[0003] While the existing technologies can solve the corresponding technical problems, they still have certain drawbacks: when the existing carbon fiber cloth stabilizer is fixed to the heel of the midsole of sports shoes, the carbon fiber cloth needs to be cut, which makes it easy for the edges to come apart and produce rough edges. When connecting the carbon fiber cloth to the midsole of sports shoes, it is often necessary to sew it to the midsole with stitching or glue it. However, the connection is not very strong and it is easy for the edges to peel up. At the same time, after a period of use, the edge unraveling of the carbon fiber cloth is easy to worsen, making it easy to be damaged and resulting in a short service life. In addition, the carbon fiber cloth is relatively flat and lacks three-dimensionality. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a drop crystal carbon fiber cloth stabilizer that is firmly connected, has a long lifespan, and a strong three-dimensional effect, as well as sports shoes incorporating the stabilizer.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a crystal-dropped carbon fiber cloth stabilizing sheet, comprising a stabilizing sheet, the stabilizing sheet comprising a carbon fiber cloth layer and a crystal-dropped layer formed on the upper surface of the carbon fiber cloth layer by a crystal-dropping process, a lower film layer of TPU material hot-pressed and shaped on the lower surface of the carbon fiber cloth layer, an upper film layer of TPU material hot-pressed and shaped on the upper surface of the crystal-dropped layer, and modified rubber filling the gaps in the carbon fiber cloth layer.
[0006] To achieve the above objectives, the present invention may also adopt the following technical solution: a sports shoe, including a midsole and an outsole fixed to the bottom surface of the midsole, an upper body fixedly provided on the midsole, the upper body having an opening at the heel position of the human foot, a stabilizing plate fixed on the side wall of the heel position of the midsole, the stabilizing plate including a carbon fiber cloth layer with modified rubber filled in the gap and a drop crystal layer formed on the upper surface of the carbon fiber cloth layer by a drop crystal process, a lower film layer of TPU material hot-pressed and shaped on the lower surface of the carbon fiber cloth layer, and an upper film layer of TPU material hot-pressed and shaped on the upper surface of the drop crystal layer.
[0007] A further improvement is that the outer surface of the shoe upper, located at the heel of the human foot, is also fixedly provided with a heel cover shell that has the same structure as the stabilizing plate.
[0008] A further improvement is that a tongue extending towards the toe is sewn onto the upper at the entrance.
[0009] A further improvement is that the upper body is also fitted with shoelaces above the tongue.
[0010] After adopting the above technical solution, the beneficial effects of this utility model are as follows: This utility model forms a drip crystal layer on the upper surface of the carbon fiber cloth layer through a drip crystal process, thereby improving the overall integrity of the carbon fiber cloth under the binding effect of the drip crystal layer. During cutting, the cutting edge is bonded and fixed by the drip crystal layer, thus preventing the edge from cracking and producing burrs during cutting. At the same time, during fixing, the lower film layer is hot-pressed to the midsole. After being heated, the lower film layer melts and solidifies, adhering and fusing to the side of the midsole. The fixing strength is high, and it is not easy to fall off or curl up. Moreover, since the thickness of the drip crystal layer can be controlled by the drip crystal time, the overall three-dimensionality of the stabilizer is greatly improved. Attached Figure Description

[0015] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0016] See Figure 1-3 As shown, the technical solution adopted in this specific embodiment is: a drop crystal carbon fiber cloth stabilizing sheet, including a stabilizing sheet 1, the stabilizing sheet 1 including a carbon fiber cloth layer 11 and a drop crystal layer 12 formed on the upper surface of the carbon fiber cloth layer 11 by a drop crystal process, and a TPU material lower film layer 14 hot-pressed and shaped on the lower surface of the carbon fiber cloth layer 11. During production, the carbon fiber cloth layer 11 is first taken out. Multiple layers of carbon fiber cloth can be laid to form the carbon fiber cloth layer 11 to increase the three-dimensional effect. Then, the raw material of the drop crystal layer 12 is hot-melted, preferably silicone, to make the raw material of the drop crystal layer 12 flow. Then, the flowing raw material of the drop crystal layer 12 is dropped onto the carbon fiber cloth layer 11 by a guiding tool. At this time, the drop crystal time can be controlled to control the thickness of the drop crystal layer 12. After the drop crystal layer 12 is formed, the integrity of the carbon fiber cloth layer 11 is improved under the binding effect of the drop crystal layer 12. When cutting, the cutting edge is The drop crystal layer 12 is bonded and fixed, thus preventing the edges from cracking and producing burrs during cutting. Simultaneously, during fixation, a TPU lower film layer 14 is hot-pressed onto the underside of the carbon fiber cloth layer 11. When connecting to the foamed midsole, the lower film layer 14 can be hot-melted using a hot-pressing process, fusing it with the foamed midsole to form a unified whole. Compared to the traditional method of gluing or sewing the carbon fiber cloth layer 11, this method offers higher fixation strength, better integration, and reduces the likelihood of edge lifting. Furthermore, when cutting the stabilizer 1 before use, the cut edges of the carbon fiber cloth layer 11 are bonded and fixed with modified rubber, preventing cracking and burrs during cutting, resulting in a more aesthetically pleasing and durable product. The varying thickness of the drop crystal layer 12 adds a sense of layering and three-dimensionality to the stabilizer 1, further enhancing its aesthetic appeal.
[0017] The upper surface of the crystal layer 12 is hot-pressed with a TPU upper film layer 13, which helps to protect the carbon fiber cloth layer 11 and the crystal layer 12, making them less susceptible to scratches and wear, and extending their service life. The light transmittance of the TPU material also ensures the reflective effect of light shining on the carbon fiber cloth layer 11.
[0018] Modified rubber is filled in the gaps of the carbon fiber cloth layer 11. By immersing the carbon fiber cloth layer 11 in the modified rubber solution and drying it, the integrity of the carbon fiber cloth layer 11 can be further improved, and it is less likely to produce burrs when cutting.
[0019] This utility model also provides a sports shoe, including a midsole 2 and an outsole 3 fixed to the bottom surface of the midsole 2. An upper body 4 is fixedly provided on the midsole 2, and the upper body 4 has an entry point 5 at the heel position of the human foot. The shoe is characterized in that a stabilizing plate 1 is fixed to the side wall at the heel position of the midsole 2. The stabilizing plate 1 includes a carbon fiber cloth layer 11 with modified rubber filled in the gaps, and a crystal layer 12 formed on the upper surface of the carbon fiber cloth layer 11 by a crystal-dropping process. A TPU lower film layer 14 is hot-pressed and shaped onto the lower surface of the carbon fiber cloth layer 11. During use, the foot enters through the entry point 5. Entering the cavity formed by the midsole 2 and the upper 4, the shoe is now ready to wear. During nighttime movement, the reflective carbon fiber fabric layer 11 reflects light, improving safety. Simultaneously, during the processing and fixing of the stabilizer 1, multiple layers of carbon fiber fabric can be laid to form the carbon fiber fabric layer 11, increasing its three-dimensional effect. Subsequently, the raw material for the hot-melt drop crystal layer 12, preferably silicone, is used for drop crystal formation. The hot-melt material of the drop crystal layer 12 becomes fluid, and then a guiding tool is used to drop the fluid drop crystal layer 12 material onto the carbon fiber fabric layer 11. The thickness of the drop crystal layer 12 can be controlled by adjusting the drop crystal time. After the drop crystal layer 12 is formed, the overall integrity of the carbon fiber cloth layer 11 is improved under the binding effect of the drop crystal layer 12. During cutting, the cutting edges are bonded and fixed by the drop crystal layer 12, thus preventing the edges from cracking and producing burrs during cutting. At the same time, during fixing, the TPU material lower film layer 14 is hot-pressed and fixed to the lower surface of the carbon fiber cloth layer 11. When connecting with the foamed material midsole, the lower film layer 14 can be hot-melted through a hot-pressing process and its heat... The fusion process integrates the carbon fiber cloth layer 11 with the foamed material midsole to form a whole. Compared with the traditional method of fixing by gluing or sewing the carbon fiber cloth layer 11, the fixing strength is higher, the integrity is better, and it is less likely to cause edge lifting. At the same time, when the stabilizer 1 is cut before use, the cut edges of the carbon fiber cloth layer 11 of the stabilizer 1 are bonded and fixed by modified rubber, so that the edges will not crack and produce rough edges during cutting. The aesthetics are higher and the durability is greater. In addition, the thickness variation of the drop crystal layer 12 brings a sense of layering and three-dimensionality to the stabilizer 1, making it more aesthetically pleasing.
[0020] The outer surface of the upper body 4 located at the heel of the human foot is also fixed with a heel cover shell 8 with the same structure as the stabilizer 1, which helps to increase the reflective area, further improve the safety of wearing, and at the same time improve the heel's resistance to deformation, thereby improving the stability when wearing.
[0021] The upper surface of the crystal layer 12 is hot-pressed with a TPU upper film layer 13, which helps to protect the carbon fiber cloth layer 11 and the crystal layer 12, making them less susceptible to scratches and wear, and extending their service life. The light transmittance of the TPU material also ensures the reflective effect of light shining on the carbon fiber cloth layer 11.
[0022] The upper body 4 is also sewn with a tongue 6 that extends towards the toe at the entrance 5, which helps to improve the protection of the instep when wearing the shoe, reduce the pressure on the instep, and significantly improve the wearing experience.
[0023] The upper body 4 is located above the tongue 6 and is also fitted with shoelaces 7, which helps to control the tightness of the upper body 4 and makes the shoe less likely to slip off the foot when worn.
[0024] The working principle of this invention is as follows: When using this invention, the foot enters the cavity formed by the midsole 2 and the upper 4 through the insertion port 5, thus completing the wearing process. During nighttime movement, the reflective carbon fiber fabric layer 11 reflects light, improving safety. Simultaneously, during the processing and fixing of the stabilizing plate 1, multiple layers of carbon fiber fabric can be laid to form the carbon fiber fabric layer 11, increasing its three-dimensional effect. Then, the raw material for the hot-melt drip crystal layer 12, preferably silicone, is dripped, causing the raw material of the drip crystal layer 12 to become fluid. A guiding tool is then used to drip the fluid raw material of the drip crystal layer 12 onto the carbon fiber fabric layer 11. The dripping time can be controlled to control the thickness of the drip crystal layer 12. After the drip crystal layer 12 is formed, the overall integrity of the carbon fiber fabric layer 11 is improved under the binding effect of the drip crystal layer 12. During cutting, the cut edges are protected by the drip crystal layer 12. The carbon fiber cloth layer 11 is bonded and fixed, thus preventing the edges from cracking and producing burrs during cutting. Simultaneously, during fixing, a TPU lower film layer 14 is hot-pressed and fixed to the lower surface of the carbon fiber cloth layer 11. When connecting it to the foamed midsole, the lower film layer 14 can be hot-melted through a hot-pressing process, fusing it with the foamed midsole to form a whole. Compared to the traditional fixing method of gluing or sewing the carbon fiber cloth layer 11, this method provides higher fixing strength, better integration, and is less prone to edge lifting. Furthermore, when cutting the stabilizer 1 before use, the cut edges of the carbon fiber cloth layer 11 are bonded and fixed with modified rubber, preventing cracking and burrs during cutting, resulting in higher aesthetics and greater durability. The varying thickness of the droplet layer 12 adds a sense of layering and three-dimensionality to the stabilizer 1, further enhancing its aesthetics.
