Description

Technical Field

[0001] This utility model relates to the field of footwear materials technology, and in particular to a lightweight, high-resilience module and a sole. Background Technology

[0002] With the increasing health awareness of people, sports such as running and hiking are becoming more and more popular. During exercise, the sole of the shoe will bear the impact of the body's own weight and the ground reaction force at the moment of contact with the ground. This impact can easily cause damage to the knee joint, ankle joint, etc. Therefore, the cushioning performance of the sole has become one of the core indicators of sports shoe design. At present, the cushioning structure of the sole mainly includes material cushioning, structural cushioning and air cushioning. Most of the existing cushioning support structures are integrally molded and have block shapes, lacking independent modular design. It is difficult to flexibly adjust the support performance and local hardness according to the pressure distribution of different areas of the sole, and they also have a certain weight. Utility Model Content

[0003] Therefore, in order to address the above problems, this utility model proposes a lightweight, high-resilience module and a shoe sole.

[0004] To achieve the above objectives, the technical solution of this utility model is to provide a lightweight and high-resilience module, including: a support component, wherein the support component is formed by stacking and connecting several support layers sequentially in the vertical direction; Each support layer includes an outer ring and an inner mesh disposed inside the outer ring, wherein the inner mesh is formed continuously with the outer ring, or the inner mesh is formed integrally with the outer ring; The outer ring dimensions of each of the support layers are different, and the outer ring dimension of the lower support layer is greater than or equal to the outer ring dimension of the upper support layer; Adjacent support layers are fixedly connected.

[0005] A further improvement is that the inner mesh is a hollow structure composed of several ribs, which are interlaced, parallel, or arranged at a certain angle to form a grid, honeycomb, wave, diagonal, or other hollow shapes.

[0006] A further improvement is that the outer ring has a circular, elliptical, rectangular, polygonal, or irregular shape, and the outer ring shapes of different support layers in the same support component can be different.

[0007] A further improvement is that multiple smaller support layers can be connected to the support layer, and the multiple smaller support layers are spaced apart from each other in the horizontal direction.

[0008] A further improvement is that it also includes a protective layer that covers the outer surface of the support component.

[0009] A further improvement is that the support component has several cavities inside, which are enclosed by the inner mesh ribs of the adjacent support layers. The cross-sectional shape of the cavity can be adjusted according to the arrangement direction, density and outer contour shape of the ribs.

[0010] A further improvement is that the support component is a 3D printed one-piece structure.

[0011] A further improvement is that the outer ring's contour shape is set according to the plantar pressure distribution, with different outer ring shapes for the outer forefoot, inner forefoot, or heel areas.

[0012] A further improvement is that the support layer is made of TPU, TPEE, or PEBA.

[0013] In addition, there is another type of sole that uses the lightweight, high-resilience module from the above-mentioned solution.

[0014] The advantages and beneficial effects of this utility model are as follows: With its simple structure and convenient use, this invention addresses the problems of existing shock-absorbing support structures, which are mostly integrally molded, lack modular design, are difficult to flexibly adjust support performance and local hardness according to the distribution of foot pressure, and are also heavy. By designing the support component as multiple independent modular support layers, each support layer has an outer ring and an inner mesh, and the outer ring of each layer is larger at the bottom and smaller at the top. This allows for flexible combination of support layers according to the pressure requirements of different areas, achieving differentiated adjustment of local hardness and support performance. At the same time, the inner mesh adopts a hollow structure, which significantly reduces the weight of the module while ensuring cushioning and rebound performance, thus improving wearing comfort.

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0017] like Figures 1-4 As shown, a lightweight, high-resilience module includes: a support component 1, which is formed by stacking and connecting several support layers 2 in a vertical direction; Each support layer 2 includes an outer ring 3 and an inner mesh 4 disposed inside the outer ring 3. The inner mesh 4 is formed continuously with the outer ring 3, or the inner mesh 4 is formed integrally with the outer ring 3. The outer ring 3 of each of the support layers 2 has different sizes, and the outer ring 3 of the lower support layer 2 is larger than or equal to the outer ring 3 of the upper support layer 2. Adjacent support layers 2 are fixedly connected; On the one hand, the outer ring 3 and the inner mesh 4 work together to form a stable support layer 2. On the other hand, the size relationship between the bottom and the top makes the module have a buffering characteristic of being soft on top and hard on the bottom, which reduces the manufacturing difficulty and weight.

[0018] Furthermore, as an optional implementation, in order to enrich the buffering form of the inner mesh 4 and adapt to different stress requirements, the inner mesh 4 is a hollow structure composed of several ribs 5. The ribs 5 are interlaced, parallel, or arranged at a certain angle to form a grid, honeycomb, wave, diagonal, or other hollow shape. By changing the arrangement direction and density of the ribs 5, the local elasticity and support strength of the support layer 2 can be flexibly adjusted, thereby meeting the differentiated requirements of different areas of the sole for shock absorption and support.

[0019] Furthermore, as an optional implementation, to enhance functionality and differentiation, such as Figure 3 , 4 As shown, the support component 1 has a plurality of cavities 6 inside. The cavity 6 is surrounded by the ribs 5 of the inner mesh 4 of the adjacent support layer 2. The cross-sectional shape of the cavity 6 can be adjusted according to the arrangement direction, density and sparseness of the ribs 5 and the outline shape of the outer ring 3. like Figure 3 , 4 As shown, by controlling the arrangement direction and density of the ribs 5 in different support layers 2, cavities 6 of different shapes, sizes and distributions can be formed inside the support component 1, thereby changing the local density and support stiffness of the support layer 2 to adapt to the pressure requirements of different areas of the foot. At the same time, the presence of cavities 6 reduces the amount of material used, which helps to reduce the overall weight and improve wearing comfort.

[0020] Furthermore, as an optional implementation, in order to improve the matching degree between the module and the shape of the foot, the outline shape of the outer ring 3 is circular, elliptical, rectangular, polygonal or irregular, and the outer ring 3 of different support layers 2 in the same support component 1 can have different shapes. By designing the outer ring 3 to adapt to different shapes of the foot outline, the support layer 2 can better fit the foot structure, improve wearing comfort, and avoid local stress concentration caused by a single shape.

[0021] Furthermore, as an optional implementation, in order to achieve the distribution of multiple smaller support layers 2 on the same larger support layer 2 and optimize the stress distribution, multiple smaller support layers 2 can be connected to the support layer 2. The multiple smaller support layers 2 are spaced apart from each other in the horizontal direction. In this way, the upper small support layer 2 can distribute and transfer the pressure to the lower large support layer 2, forming multi-point support, which is beneficial to improving overall stability and reducing local pressure.

[0022] Furthermore, as an optional implementation, in order to protect the support component 1 from external wear and impact while maintaining the integrity of the module's appearance, a protective layer is also included. The protective layer covers the outer surface of the support component 1 and can play the role of dustproof, wear-resistant and buffering external impact. However, it should be noted that the protective layer does not necessarily have to achieve an airtight fit of the support component 1, and it may have ventilation holes.

[0023] Furthermore, as an optional implementation, in order to simplify the manufacturing process, ensure structural accuracy and reduce assembly steps, the support component 1 is a 3D printed one-piece structure. Using 3D printing technology, the outer ring 3, inner mesh 4 and each support layer 2 can be directly formed into one piece, avoiding the complicated process of traditional separate manufacturing and then bonding. At the same time, it is conducive to realizing complex inner mesh 4 structures and personalized shape designs.

[0024] Furthermore, as an optional implementation, in order to customize the design for the distribution of plantar pressure, the outline shape of the outer ring 3 is set according to the distribution of plantar pressure. The outer ring 3 of the outer side of the forefoot, the inner side of the forefoot, or the heel area has different shapes. In this way, the shape and size of the outer ring 3 of the corresponding support layer 2 can be optimized according to the magnitude and direction of the force on each area of ​​the sole, thereby improving the targeting of cushioning and support and further enhancing sports comfort.

[0025] Furthermore, as an optional implementation, in order to ensure that the module has excellent resilience and durability, the support layer 2 is made of TPU, TPEE or PEBA. These materials have good elastic recovery ability, fatigue resistance and light weight, which enables the support layer 2 to quickly recover its shape after repeated pressure, while taking into account the overall lightweight requirements of the module.

[0026] Furthermore, as an optional implementation, in order to apply the above-mentioned lightweight and high-rebound module to actual products, a shoe sole adopts the lightweight and high-rebound module. By setting the lightweight and high-rebound module in the forefoot, arch, or heel areas of the shoe sole, it can provide the shoe sole with lightweight, high rebound and good cushioning support performance, which is especially suitable for running, hiking and other sports scenarios.

[0027] Working principle: The support component 1 is composed of several support layers 2 stacked and connected in the vertical direction. Each support layer 2 consists of an outer ring 3 and an inner hollow mesh 4. When under force, the smaller upper support layer 2 deforms first, distributing the pressure to the larger lower support layer 2. The outer ring 3 provides structural support and positioning. The inner mesh 4 absorbs impact energy through the bending and stretching deformation of the ribs 5 and quickly recovers after the load is removed, achieving rebound. The size relationship of the larger lower part and the smaller upper part creates a buffer gradient of soft upper part and hard lower part, which takes into account both comfortable foot feel and support stability.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The embodiments described above are merely illustrative of several implementations of this utility model. While the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
