Description

Technical Field

[0001] This utility model relates to the field of shoe manufacturing technology, and in particular to an injection-molded shoe upper. Background Technology

[0002] The upper is the upper structure of a footwear product, typically covering the instep, sides, and part of the ankle area, and connects with the sole to form a complete shoe body.

[0003] However, traditional injection-molded shoe uppers mostly use soft plastics for comfort. Although these materials can meet the basic molding requirements, they are not hard enough and cannot provide sufficient resistance to torsion and deformation.

[0004] Therefore, it is necessary to provide an injection-molded shoe upper to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the technical problem that traditional injection-molded shoe uppers mostly use soft plastics, which are difficult to provide sufficient resistance to torsion and deformation, this utility model provides an injection-molded shoe upper.

[0006] The injection-molded shoe upper provided by this utility model includes: an upper, the upper having an outer surface layer, a supporting middle layer and an adhesive inner layer, the supporting middle layer being located inside the outer surface layer, the adhesive inner layer being located inside the supporting middle layer, the outer surface layer having a nano-coating, the supporting middle layer having a TPU skeleton, and the adhesive inner layer having a fabric composite material.

[0007] Preferably, the bottom of the shoe upper is provided with a sole, and the sole is provided with a rubber bottom layer, an impact-resistant layer, a shock-absorbing layer and a protective layer. The impact-resistant layer is located above the rubber bottom layer, the shock-absorbing layer is located above the impact-resistant layer, and the protective layer is located above the shock-absorbing layer.

[0008] Preferably, the surface of the shoe upper is provided with a textured layer, and the textured layer has multiple stripes.

[0009] Preferably, the shoe upper has multiple shoelace holes, and shoelaces are threaded through the shoelace holes.

[0010] Preferably, the shoe upper is provided with a tongue to enhance the shoe's fit and support.

[0011] Preferably, the surface of the shoe upper is provided with a microporous breathable membrane for breathability and moisture wicking.

[0012] Preferably, the protective layer is provided with a breathable insole, and the breathable insole is provided with an antibacterial layer.

[0013] Compared with related technologies, the injection-molded shoe upper provided by this utility model has the following beneficial effects: This utility model provides an injection-molded shoe upper: 1. The outer layer features a nano-coating to enhance the shoe's waterproof performance, preventing water from entering the shoe in humid environments and keeping feet dry. The TPU skeleton within the mid-layer supports and effectively improves the upper's torsional and deformation resistance. During exercise, the TPU skeleton can withstand the torsional forces generated by the foot, maintaining the shoe's shape stability and providing reliable support, significantly improving the shoe's athletic performance and safety. The inner layer incorporates a soft, skin-friendly fabric composite material that conforms well to the foot, reducing friction and discomfort. Simultaneously, the fabric composite material offers excellent breathability, allowing sweat to evaporate quickly, keeping feet dry and preventing stuffiness and odor, thus enhancing comfort and making it suitable for extended wear. The shoe utilizes a multi-layered structure consisting of a rubber bottom layer, an impact-resistant layer, a shock-absorbing layer, and a protective layer. Each layer has a clear function and works in concert, forming a complete protective system from the bottom for grip and impact resistance, to the mid-layer for shock absorption, and finally to the top for protection. 2. Through the multiple stripes on the textured layer, various unique patterns and shapes can be presented according to needs. The textured upper has a more three-dimensional and layered feel, which can attract consumers' attention, meet the pursuit of fashion and individuality of different groups, and enhance the overall aesthetics and market competitiveness of the shoes. Through multiple shoelace holes and shoelaces, precise foot wrapping can be achieved. Adjusting the tightness of the shoelaces can make the shoes fit tightly around the feet, providing even pressure distribution and reducing the slipping and shaking of the feet in the shoes. 3. The tongue fits snugly to the contours of the instep, filling the gap between the shoe upper and the foot. The tongue evenly distributes the pressure applied by the shoelaces across the entire instep, preventing discomfort caused by excessive local pressure. The microporous breathable membrane allows sweat produced by the feet to quickly escape to the outside of the shoe as water vapor, shortening the time moisture stays inside the shoe and keeping the inside environment dry. The microporous breathable membrane not only allows moisture to escape but also allows fresh air from outside to enter the shoe, forming good air circulation. This air circulation can remove heat and odor from inside the shoe, keeping the feet fresh and comfortable. The porous structure of the breathable insole allows air to flow freely inside the insole and the shoe space. The antibacterial agents in the antibacterial layer can destroy the cell structure or metabolic processes of bacteria and fungi, thereby inhibiting their growth and reproduction.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please refer to the following: Figures 1-4 ,in, Figure 1 A front view structural schematic diagram of a preferred embodiment of the injection-molded shoe upper 1 provided by this utility model; Figure 2 A front cross-sectional view of a preferred embodiment of the injection-molded shoe upper 1 provided by this utility model; Figure 3 A top view of a preferred embodiment of the injection-molded shoe upper 1 provided by this utility model; Figure 4 for Figure 2 The diagram shows an enlarged view of part A.

[0018] The injection-molded shoe upper includes: an upper 1, wherein the upper 1 has an outer surface layer 2, a supporting middle layer 3, and an inner bonding layer 4. The supporting middle layer 3 is located inside the outer surface layer 2, and the inner bonding layer 4 is located inside the supporting middle layer 3. The outer surface layer 2 has a nano-coating 5, the supporting middle layer 3 has a TPU skeleton 6, and the inner bonding layer 4 has a fabric composite material 7. The nano-coating 5 on the outer surface layer 2 enhances the waterproof performance of the upper 1, making it less likely for water to enter the shoe in wet environments and keeping the feet dry. The TPU skeleton 6 in the supporting middle layer 3 effectively improves the waterproof performance of the upper. The TPU skeleton 6 has excellent torsional and deformation resistance. During exercise, it can withstand the torsional force generated by the foot, maintain the shape stability of the upper 1, and provide reliable support for the foot, greatly improving the athletic performance and safety of the shoe. The inner layer 4 is made of fabric composite material 7, which is soft and skin-friendly, and can fit well with the skin of the foot, reducing friction and discomfort. At the same time, the fabric composite material 7 has good breathability, which allows sweat to evaporate in time, keeping the feet dry and avoiding stuffiness and odor, thereby improving wearing comfort and making it suitable for long-term wear.

[0019] The bottom of the shoe upper 1 is provided with a sole 8, on which a rubber bottom layer 9, an impact-resistant layer 10, a shock-absorbing layer 11, and a protective layer 12 are provided. The impact-resistant layer 10 is located above the rubber bottom layer 9, the shock-absorbing layer 11 is located above the impact-resistant layer 10, and the protective layer 12 is located above the shock-absorbing layer 11. By adopting a multi-layer structure of rubber bottom layer 9, impact-resistant layer 10, shock-absorbing layer 11, and protective layer 12, each layer has a clear function and works together to form a complete protection system, from the bottom grip and impact resistance, to the middle shock absorption, and then to the upper protection.

[0020] The surface of the shoe upper 1 is provided with a textured layer 13, which has multiple stripes. Through the multiple stripes on the textured layer 13, various unique patterns and shapes can be presented according to needs. The shoe upper 1 with the textured layer 13 has a more three-dimensional and layered feel, which can attract consumers' attention, meet the pursuit of fashion and individuality of different groups, and enhance the overall aesthetics and market competitiveness of the shoes.

[0021] The upper 1 of the shoe has multiple shoelace holes 14, and shoelaces 15 are threaded through the shoelace holes 14. Through the multiple shoelace holes 14 and shoelaces 15, the shoe can be precisely wrapped around the foot. By adjusting the tightness of the shoelaces 15, the shoe can fit tightly around the foot, providing a uniform pressure distribution and reducing the slipping and shaking of the foot inside the shoe.

[0022] The upper 1 is provided with a tongue 16 to enhance the fit and support of the upper. The tongue 16 can closely fit the contour of the instep and fill the gap between the upper 1 and the foot. The tongue 16 will evenly distribute the pressure applied by the shoelaces to the entire instep, avoiding discomfort caused by excessive local pressure.

[0023] The surface of the shoe upper 1 is provided with a microporous breathable membrane 17 for breathability and moisture wicking. Through the microporous breathable membrane 17, the sweat produced by the feet can be quickly discharged to the outside of the shoe in the form of water vapor through the micropores, which can shorten the residence time of moisture in the shoe and keep the environment inside the shoe dry. The microporous breathable membrane 17 not only allows moisture to be discharged, but also allows fresh air from the outside to enter the shoe, forming a good air circulation. This air circulation can remove heat and odor from the shoe, keeping the feet fresh and comfortable.

[0024] The protective layer 12 is provided with a breathable insole 18, and the breathable insole 18 is provided with an antibacterial layer 19. The porous structure of the breathable insole 18 allows air to flow freely inside the insole and inside the shoe. The antibacterial agent in the antibacterial layer 19 can destroy the cell structure or metabolic process of bacteria and fungi, thereby inhibiting their growth and reproduction.

[0025] The working principle of the injection-molded shoe upper 1 provided by this utility model is as follows: During injection molding, a suitable high-strength, wear-resistant, and soft plastic material is selected as the material for the outer surface layer 2. The TPU (thermoplastic polyurethane elastomer) material is processed into the shape of the TPU skeleton 6 through a specific mold. The TPU skeleton 6 is then embedded into the material of the supporting middle layer 3. The material of the supporting middle layer 3 is selected to have a certain degree of flexibility and elasticity. After being combined with the TPU skeleton 6, it can ensure the overall flexibility of the shoe upper 1 and provide sufficient support and torsional resistance through the TPU skeleton 6. Finally, a soft and comfortable fabric composite material 7 is selected and evenly distributed in the bonding inner layer 4. The fabric composite material 7 can provide good skin-friendliness and breathability, making the wearer's feet feel comfortable. The prepared outer surface layer 2, supporting middle layer 3, and bonding inner layer 4 are assembled together in sequence from the outside to the inside. Through processes such as bonding and hot pressing, the layers are tightly bonded to form a complete shoe upper 1. During connection, high-quality, wear-resistant rubber material with good grip is selected, and the shape of the rubber bottom layer 9 is formed by mold injection molding. The bottom of the rubber bottom layer 9 is designed with specific textures to increase friction with the ground and improve stability during walking and exercise. The impact-resistant layer 10 is made of high-strength, high-toughness engineering plastics or special composite materials. The shock-absorbing layer 11 is made of materials with good elasticity and energy absorption properties, such as EVA (ethylene-vinyl acetate copolymer) foam material, air cushion, etc. The protective layer 12 can be made of wear-resistant and tear-resistant fabric material or special plastic film. The layers are tightly bonded together by bonding, hot pressing and other processes to form a complete sole 8. The prepared sole 8 is assembled with the upper 1 to ensure that the sole 8 and the upper 1 are firmly connected to form a complete shoe. When the wearer walks or exercises, the shock-absorbing layer 11 plays a major role when the foot lands on impact. Its excellent elasticity and energy absorption properties cushion the impact force on the foot, reducing damage to the foot joints and bones, making the wearer feel more comfortable. The impact-resistant layer 10 further disperses and weakens the impact force, distributing the impact force concentrated at one point to a larger area, reducing local pressure and enhancing the impact resistance of the sole 8. The rubber bottom layer 9 contacts the ground, and its special tread design provides good grip, ensuring that the wearer will not slip during walking and exercise, guaranteeing the safety of walking and exercise. The upper 1 surface... The outer layer 2 is in direct contact with the external environment. The nano-coating 5 can effectively block the invasion of moisture, stains and bacteria, keeping the upper 1 clean and hygienic. During exercise, the foot will produce various twisting and deformation movements. The TPU skeleton 6 in the supporting middle layer 3 plays a key role. The TPU skeleton 6 has high strength and rigidity, which can resist the torsional force of the foot, prevent the upper 1 from being excessively twisted and deformed, provide stable support for the foot, and reduce the risk of sports injuries. The fabric composite material 7 that fits the inner layer 4 is in direct contact with the skin of the foot. Its soft and breathable properties can keep the foot dry and comfortable, reduce friction and stuffiness, and improve wearing comfort.

[0026] Compared with related technologies, the injection-molded shoe upper provided by this utility model has the following beneficial effects: This invention provides an injection-molded shoe upper. A nano-coating 5 on the outer surface layer 2 enhances the waterproof performance of the upper 1, preventing water from entering the shoe in humid environments and keeping feet dry. The TPU skeleton 6 within the supporting mid-layer 3 effectively improves the torsional and deformation resistance of the upper 1. During exercise, the TPU skeleton 6 can withstand the torsional forces generated by the foot, maintaining the shape stability of the upper 1 and providing reliable support for the foot, greatly improving the shoe's athletic performance and safety. The inner layer 4 contains a fabric composite material 7, which is soft and skin-friendly, conforming well to the skin of the foot and reducing friction. To reduce discomfort, the fabric composite material 7 offers excellent breathability, allowing sweat to evaporate quickly, keeping feet dry and preventing stuffiness and odor, thus enhancing comfort and making it suitable for extended wear. The multi-layered structure, consisting of a rubber bottom layer 9, an impact-resistant layer 10, a shock-absorbing layer 11, and a protective layer 12, ensures each layer has a defined function and works in tandem, forming a complete protective system from the bottom for grip and impact resistance, to the midsection for shock absorption, and finally to the top for protection. The textured layer 13 features multiple stripes that can create various unique patterns and shapes, giving the upper 1 a more three-dimensional feel and... The layered design attracts consumers' attention, satisfies the diverse pursuit of fashion and individuality among different groups, and enhances the overall aesthetics and market competitiveness of the shoes. Multiple eyelets 14 and laces 15 provide precise foot support. Adjusting the tightness of the laces 15 ensures a snug fit around the foot, providing even pressure distribution and reducing slippage and movement. The tongue 16 conforms closely to the contours of the instep, filling the gap between the upper 1 and the foot. The tongue 16 evenly distributes the pressure applied by the laces across the entire instep, preventing discomfort caused by excessive localized pressure. Microporous breathable material further enhances the shoe's appearance. The air membrane 17 allows sweat produced by the feet to be quickly expelled to the outside of the shoe in the form of water vapor through micropores, which can shorten the time that moisture stays in the shoe and keep the environment inside the shoe dry. The microporous breathable membrane 17 not only allows moisture to escape, but also allows fresh air from the outside to enter the shoe, forming a good air circulation. This air circulation can remove heat and odor from the shoe, keeping the feet fresh and comfortable. The porous structure of the breathable insole 18 allows air to flow freely inside the insole and in the shoe. The antibacterial agent in the antibacterial layer 19 can destroy the cell structure or metabolic process of bacteria and fungi, thereby inhibiting their growth and reproduction.
