Abstract
Description
Technical Field
[0001] This utility model relates to the field of footwear and apparel technology, specifically to a biomimetic leaf vein low-pressure breathable shoe upper. Background Technology
[0002] Shoes are a type of clothing accessory whose function is to protect and cover the user's feet. They are basically composed of a sole and an upper. The sole is the lower part that contacts the ground, while the upper is the upper part that is located on top of the sole. The upper covers the user's foot and connects with the sole to fix the sole to the user's foot, preventing the sole from falling off. The design of the upper can effectively improve the integration of the shoe and foot, and make the shoe more protective of the foot and provide better warmth.
[0003] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: when the existing uppers are used on long-distance running shoes, in order to improve the heat dissipation effect, the uppers are often made very thin. However, due to their lower thickness, the strength of the thin uppers will decrease, which can easily lead to the uppers failing to support the feet during running. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a biomimetic leaf vein low-pressure breathable shoe upper with high strength and good breathability.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a biomimetic leaf vein low-pressure breathable shoe upper, comprising a shoe upper body and an opening integrally formed on the shoe upper body at the heel position of the human foot, wherein a plurality of biomimetic leaf vein breathable layers are embedded and sewn into the middle section of the shoe upper body, the biomimetic leaf vein breathable layers comprising leaf vein layers embedded and sewn and fixed to the middle section of the shoe upper body, the leaf vein layers being composed of a plurality of leaf vein structures, and the biomimetic leaf vein breathable layers further comprising a frame sewn and fixed to the edge of the leaf vein layers.
[0006] A further improvement is that the upper body has an integrally formed tongue mounting opening extending towards the front end of the upper body at the edge of the insertion opening.
[0007] A further improvement is that several transverse reinforcing strips are sewn and fixed in the middle section of the upper body, and the transverse reinforcing strips extend from the front end of the upper body to the rear end of the upper body.
[0008] A further improvement is that the upper body has several ventilation holes integrally formed on the forefoot position.
[0009] A further improvement is that the leaf vein structure includes a central frame in the shape of a quadrilateral formed by yarn and a first vent integrally formed within the central frame. The four sides of the central frame are each sewn with an extension frame in the shape of a pentagon formed by yarn.
[0010] A further improvement is that the extended frame is integrally formed with a second vent.
[0011] A further improvement is that the inner wall of the second vent is provided with a yarn-formed support strip.
[0012] A further improvement is that an inner lining layer is fixedly connected to the underside of the shoe upper body.
[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: This utility model has several biomimetic leaf vein breathable layers on the upper body, which provide high-efficiency breathability. The biomimetic leaf vein breathable layer is composed of multiple leaf vein structures, with a large number of through holes and a framework composed of polygonal structures, so that the foot can achieve a high-efficiency breathability effect in this position. At the same time, the polygonal framework wraps the foot, and combined with the high-strength upper body, the upper body can ensure strength while having good breathability. During running, it can effectively dissipate heat from the foot and maintain the wrapping performance of the foot. It is highly comfortable and can also effectively prevent sports injuries caused by the upper not being able to support the foot. Attached Figure Description

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0020] See Figure 1-4As shown, the technical solution adopted in this specific embodiment is: a biomimetic leaf vein low-pressure breathable shoe upper, including a shoe upper body 1 and an opening 2 integrally formed on the shoe upper body 1 at the heel position of the human foot. A plurality of biomimetic leaf vein breathable layers 5 are embedded and sewn into the middle section of the shoe upper body 1. The biomimetic leaf vein breathable layers 5 include leaf vein layers 52 embedded and sewn into the middle section of the shoe upper body 1. The leaf vein layers 52 are composed of a plurality of leaf vein structures 521. The leaf vein structure 521 includes a four-sided central frame 21 formed by yarn and an integrally formed central frame 21. The first ventilation opening 22, and the four sides of the central frame 21 are all sewn with pentagonal extension frames 23 formed by yarn. During production, the upper body 1 is woven and formed by yarn. The yarn can be Coats Ultra yarn, which can provide high yarn strength and low yarn weight. At the same time, a groove is reserved in the middle of the upper body 1 for sewing the biomimetic leaf vein breathable layer 5. The biomimetic leaf vein breathable layer 5 is composed of multiple leaf vein structures 521. After being sewn and fixed into the upper body 1, the central frame 21 composed of the yarn of the leaf vein structure 521 is a quadrilateral knot. The shoe upper is formed with a first ventilation opening 22 inside. Extended frames 23, composed of yarn, are formed on each edge of the central frame 21 of the quadrilateral structure. These extended frames 23 are pentagonal in shape, with their bottom edges fitting together. All the yarns used are Coats Ultra yarn to achieve high yarn strength and low yarn weight. After forming, the upper is inserted into the shoe midsole. The wearer inserts the upper through the opening 2, allowing the foot to be wrapped by the upper body 1. During exercise, the high-strength upper body 1 provides high support and a secure fit. The shoe provides excellent support and, at the location of the biomimetic leaf vein breathable layer 5, allows the heat generated by foot movement to dissipate outward through the first vent 22. Combined with the quadrilateral central frame 21 and the pentagonal extended frame 23 attached to the foot, when the foot compresses the biomimetic leaf vein breathable layer 5, the central frame 21 and the extended frame 23 are stretched and deformed, thereby reducing the pressure on the foot. During running, it can effectively dissipate foot heat and maintain the support performance of the foot, providing high comfort while effectively preventing sports injuries caused by the upper not being able to support the foot.
[0021] The upper body 1 has an integrally formed tongue mounting opening 3 extending towards the front end of the upper body 1 at the edge of the insertion opening 2, which facilitates the insertion of the tongue through the tongue mounting opening 3, making the tongue installation simpler and more convenient.
[0022] Several transverse reinforcing strips 4 are sewn and fixed in the middle section of the upper body 1. The transverse reinforcing strips 4 extend from the front end of the upper body 1 to the rear end of the upper body 1. The transverse reinforcing strips 4 are composed of multiple transverse strips. They can be woven with high-strength TPU yarn or with the same yarn as the upper body 1. This helps to further enhance the transverse tensile strength of the upper body 1 and further improve the support and deformation resistance of the upper body 1 for the foot.
[0023] The upper body 1 is integrally molded with several ventilation holes 6 at the forefoot position, which helps to further improve the breathability of the upper body 1;
[0024] The biomimetic leaf vein breathable layer 5 also includes a frame 51 sewn and fixed to the edge of the leaf vein layer 52. This facilitates the process of forming the frame 51 first and then sewing the leaf vein layer 52 into the frame 51 during processing and production. This makes it easier to connect the biomimetic leaf vein breathable layer 5 with the upper body 1, while avoiding misalignment when the lower density leaf vein layer 52 is combined with the higher density upper body 1, making the surface of the leaf vein layer 52 smoother.
[0025] The extended frame 23 has a second ventilation opening 24 integrally formed, which helps to further improve the overall breathability of the shoe upper. Experiments have shown that, in conjunction with the first ventilation opening 22, the overall breathability of the shoe upper is increased by 40% compared to the breathability of traditional knitted shoe uppers.
[0026] The inner wall of the second vent 24 is provided with a yarn-formed support strip 25, which helps to improve the strength of the extension frame 23 after stretching, prevents it from being excessively deformed, and allows it to recover more quickly.
[0027] An inner lining layer 11 is also fixedly connected to the bottom of the upper body 1. The inner lining layer 11 is a high-strength woven jacquard mesh fabric, which helps to prevent the foot from directly contacting the yarn of the upper body 1 after it is put on, thus making it more comfortable to wear.
[0028] The working principle of this utility model is as follows: During production, the upper body 1 is woven from yarn. Coats Ultra yarn can be used, which provides high yarn strength and low yarn weight. A groove is pre-reserved in the middle section of the upper body 1 for sewing a biomimetic leaf vein breathable layer 5. The biomimetic leaf vein breathable layer 5 is composed of multiple leaf vein structures 521. After being sewn and fixed into the upper body 1, the central frame 21 composed of the yarn of the leaf vein structure 521 has a quadrilateral structure and a first ventilation opening 22 is formed within it. On each edge of the quadrilateral central frame 21, an extension frame 23 composed of yarn is formed. The extension frame 23 has a pentagonal structure, and its bottom edges are joined together. All of the above-mentioned yarns can be Coats Ultra yarn to obtain high yarn strength and low weight. The low yarn weight allows the upper to be easily attached to the midsole after molding. The wearer slips it on through the inlet 2, allowing the foot to be completely enveloped by the upper body 1. During exercise, the high-strength upper body 1 provides excellent support and a snug fit. Simultaneously, the biomimetic leaf vein breathable layer 5 allows heat generated during foot movement to dissipate outwards through the first vent 22. Combined with the quadrilateral central frame 21 and the pentagonal extended frame 23 attached to the foot, when the foot compresses the biomimetic leaf vein breathable layer 5, the central frame 21 and extended frame 23 stretch and deform, reducing pressure on the foot. This effectively dissipates heat while maintaining a snug fit during running, providing high comfort and preventing sports injuries caused by the upper failing to support the foot.
