Description

Technical Field

[0001] The utility model belongs to the technical field of shoe manufacturing, and particularly relates to an integrally formed heel upper structure. Background Art

[0002] Traditionally, heel uppers are assembled by sewing together components of different shapes, then reverse-stitching the front and back, gluing the sponge and heel, and then wrapping them around to create the desired soft-edge shape. Finally, the heel shape is finalized to match the last. This traditional process is not only time-consuming and cumbersome, but also produces poor shock absorption and cushioning. Consequently, the overall performance and comfort of the shoe fail to meet the wearer's expectations.

[0003] With the continuous development and progress of shoemaking technology, various intelligent technologies are increasingly being applied in the shoemaking field. New one-piece molded heel and upper are developed to overcome the shortcomings of the traditional sewing combination of shoe heels. Utility Model Content

[0006] Disclosed is an integrally formed heel upper structure, comprising a PV cotton layer, a TPU layer and a shoe lining fabric layer; the PV cotton layer, the TPU layer and the shoe lining fabric layer are arranged in order from outside to inside; a tension surface fabric layer is arranged on the outer side of the middle and lower part of the PV cotton layer; a heel cotton is arranged on the middle and upper part of the shoe lining fabric layer; the heel cotton, the tension surface fabric layer, the PV cotton layer, the TPU layer and the shoe lining fabric layer form an integral structure; the rearmost end of the tension surface fabric layer in the integral structure bulges outward to form a rear convex arc; the heel cotton is recessed inward to form a rear concave arc; ankle protection concave arcs are arranged on the upper body on both sides of the heel cotton in the integral structure.

[0007] The bottom of the concave arc of the ankle protector is located at the rear 1 / 4 of the length of the sole of the shoe last.

[0008] A hot pressing pattern is hot pressed on the tension surface fabric layer.

[0009] The tension surface cloth layer is made of soft cloth.

[0010] The PV cotton layer is made of EVA material.

[0011] The TPU layer is arranged in the middle and lower part of the integrated structure.

[0012] The curvatures of the posterior concave arc and the posterior convex arc conform to the physiological curve of the human heel.

[0013] The shoe lining layer is an integrated structure consisting of a mesh surface, a polyurethane sponge and mesh yarn; the polyurethane sponge is placed between the mesh surface and the mesh yarn.

[0014] The thickness of the polyurethane sponge is 3 mm.

[0015] Beneficial effects:

[0016] (1) The utility model designs the heel cotton, tension surface fabric layer, PV cotton layer, TPU layer and shoe lining fabric layer into an integrated structure. The various components in the cushioning module are perfectly connected together through mold pressing to form a whole. The three-dimensional molding fits the foot perfectly and can better adapt to the shape and movement of the foot.

[0017] (2) The present invention eliminates the traditional processes of cutting the sheet, marking the edge of the sheet, overlapping the parts, and gluing the main heel, sponge and flip-up sponge. It can be made by 3D printing in the existing technology, reducing the number of assembly steps, thereby greatly improving production efficiency.

[0018] (3) The utility model uses various materials to stack and perfectly connect, and the TPU layer is located in the middle and lower end of the integrated structure, which plays a good role in support and stable protection.

[0019] (4) The heel pad in the present invention is arranged at the upper end of the inner cavity, which improves the fit and comfort of the foot.

[0020] (5) The shoe lining layer in the present invention is located at the innermost side of the shoe cavity, which can provide good air permeability, keep the feet dry, and improve wearing comfort.

[0021] (6) The utility model is designed as an integrated structure with no overlaps or interfaces between the layers, making the product lighter, stronger and more durable.

[0022] (7) The utility model is designed as an integrated structure, which makes the shoe fit the foot perfectly, reduces the impact on the foot during exercise, protects the ankle and knee joints, and improves exercise efficiency and functionality.

[0023] (8) The utility model is designed as an integrated structure, which simplifies the production process and makes the production process more automated and efficient. It is an important innovation in the design of modern sports shoes.
