Description

Technical Field

[0001] The present application relates to the field of shock-absorbing shoe soles, and in particular to a lightweight shock-absorbing shoe sole. Background Art

[0002] With the popularization of sports and leisure lifestyles, consumers' demands for footwear have no longer been limited to basic protection and wearing needs, but have paid more attention to real-time performance, lightweight and functionality. Among them, shock-absorbing performance and light weight are important criteria for measuring the quality of shoe soles.

[0003] Most of the shock-absorbing means of existing shock-absorbing shoe soles are material shock absorption. By adding elastic materials such as EVA (ethylene-vinyl acetate copolymer), rubber or PU (polyurethane) to the shoe sole, the shock-absorbing effect can be achieved. Although these materials have good cushioning performance, they often have the problem of being too heavy. Summary of the Utility Model

[0004] In order to balance the light weight and shock-absorbing performance of the shoe sole, the present application provides a lightweight shock-absorbing shoe sole.

[0005] The lightweight shock-absorbing shoe sole provided by the present application adopts the following technical solutions:

[0006] A lightweight shock-absorbing shoe sole includes a shoe sole body. A lightweight cavity is formed on the upper surface of the shoe sole body and extends along the length direction of the shoe sole body. A plurality of first shock-absorbing parts are arranged in the lightweight cavity of the shoe sole body, and the plurality of first shock-absorbing parts are evenly distributed in the lightweight cavity. The first shock-absorbing parts are made of D3O material. A plurality of second shock-absorbing parts are arranged on both sides of the first shock-absorbing parts. The bottom wall of the second shock-absorbing parts is connected to the bottom wall of the lightweight cavity, and the plurality of second shock-absorbing parts are arranged at intervals along the length direction of the first shock-absorbing parts.

[0007] By adopting the above technical solutions, the molecules of D3O material have special connections. When at rest or moving slowly, these molecules are in a free state, making the material as a whole soft and elastic. However, when the material is subjected to a rapid impact, the connections between the molecules will quickly lock, forming a structure similar to a solid, thereby effectively reducing shock and resisting impact. Using this shoe sole to make shoes, when the wearer is walking or running and jumping, under normal conditions, the shoe sole is relatively soft, ensuring wearing comfort. When the shoe sole is subjected to impact and collision, the molecules between the first shock-absorbing parts quickly lock, playing a good shock-absorbing and buffering role. The second shock-absorbing parts play a supporting role for the first shock-absorbing parts to ensure the supporting performance of the shoe sole under normal conditions. And because a lightweight cavity is formed on the shoe sole, the lightweight performance of the shoe sole can be ensured.

[0008] Optionally, the first shock-absorbing parts extend along the width direction of the lightweight cavity.

[0009] By adopting the above technical solution, on the one hand, the length of the first shock-absorbing part is neither too long nor too short, ensuring both shock-absorbing performance and support performance; on the other hand, it also facilitates the bending of the sole, ensuring wearing comfort.

[0010] Optionally, the second shock-absorbing part is integrally formed with the sole body.

[0011] By adopting the above technical solution, the connection stability between the second shock-absorbing part and the sole body is ensured, and further the support performance of the second shock-absorbing part for the first shock-absorbing part is ensured.

[0012] Optionally, a plurality of the second shock-absorbing parts on both sides of the first shock-absorbing part are symmetrically arranged.

[0013] By adopting the above technical solution, the support of the second shock-absorbing parts on both sides of the first shock-absorbing part is relatively symmetrical, ensuring the force uniformity and stability of the first shock-absorbing part.

[0014] Optionally, the second shock-absorbing parts corresponding to adjacent first shock-absorbing parts are arranged staggeredly.

[0015] By adopting the above technical solution, the distribution of a plurality of second shock-absorbing parts in the lightweight cavity is relatively uniform, thereby improving the support uniformity of the second shock-absorbing parts and at the same time improving the wearing comfort of the shoes made of this sole.

[0016] Optionally, a plurality of hollow balls are arranged in the lightweight cavity, and both sides of each hollow ball are respectively abutted against two adjacent second shock-absorbing parts.

[0017] By adopting the above technical solution, the outer wall of the hollow ball abuts against the second shock-absorbing part. During the walking process of the wearer, the sole body, the first shock-absorbing part and the second shock-absorbing part deform, and friction is generated between the hollow ball during the deformation process, consuming energy and further improving the shock-absorbing effect.

[0018] Optionally, a connecting edge is arranged on the circumferential side of the sole body, and the connecting edge is arranged to surround the sole body circumferentially.

[0019] By adopting the above technical solution, it is convenient to connect the sole body to the shoe upper.

[0020] Optionally, the connecting edge is integrally formed with the sole body.

[0021] By adopting the above technical solution, the connection stability between the connecting edge and the sole body is ensured, and further the connection stability between the sole body and the shoe upper is ensured.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By providing a lightweight cavity in the sole body, the sole is made relatively lightweight. By providing a first shock-absorbing part made of D3O material in the lightweight cavity and providing second shock-absorbing parts on both sides of the first shock-absorbing part, the second shock-absorbing parts are used to support the first shock-absorbing part to ensure the support performance and shock-absorbing performance of the sole.

[0024] 2. By symmetrically arranging the second shock-absorbing parts on both sides of the first shock-absorbing part and integrally forming the second shock-absorbing parts with the sole body, the wearing comfort and support performance of the shoes made of this sole are ensured.

[0025] 3. By providing hollow balls in the lightweight cavity and making the hollow balls abut against the second shock-absorbing parts, the shock-absorbing performance and support performance of the sole are further improved, and the wearing comfort of the shoes made of this sole is also improved.

[0029] The following Figure 1-2 further describes the present application in detail.

[0030] The embodiment of the present application discloses a lightweight shock-absorbing sole.

[0031] Embodiment 1

[0032] Referring to Figure 1 , a lightweight shock-absorbing sole includes a sole body 1. A lightweight cavity 11 is provided on the upper surface of the sole body 1, and the lightweight cavity 11 extends along the length direction of the sole body 1. The sole body 1 is provided with a plurality of first shock-absorbing parts 12 in the lightweight cavity 11, and the first shock-absorbing parts 12 are made of D3O material. Second shock-absorbing parts 13 are provided on both sides of the plurality of first shock-absorbing parts 12. The bottom wall of the second shock-absorbing parts 13 is connected to the bottom wall of the cavity of the lightweight cavity 11, and the plurality of second shock-absorbing parts 13 are arranged at intervals along the length direction of the first shock-absorbing parts 12.

[0033] There are special connections between the molecules of D3O material. When at rest or moving slowly, these molecules are in a free state, making the material as a whole soft and elastic. However, when the material is subjected to a rapid impact, the connections between the molecules will quickly lock, forming a structure similar to a solid, thus effectively damping and resisting the impact. Using this sole to make shoes, during the process of the wearer walking, running or jumping, under normal conditions, the sole is relatively soft to ensure wearing comfort. When the sole is subjected to impacts and collisions, the molecules between the first damping parts 12 quickly lock, playing a good role in damping and buffering. Among them, the second damping part 13 plays a supporting role for the first damping part 12 to ensure the supporting performance of the sole under normal conditions. And because the sole is provided with a lightweight cavity 11, the lightweight performance of the sole can be ensured.

[0034] Among them, a plurality of first damping parts 12 are all arranged along the width direction of the lightweight cavity 11, and the plurality of first damping parts 12 are arranged at intervals along the length direction of the lightweight cavity 11. On the one hand, it makes the length of the first damping part 12 neither too long nor too short, ensuring both the damping performance and the supporting performance; on the other hand, it is also convenient for the sole to bend, ensuring wearing comfort.

[0035] In other embodiments, the first damping part 12 can also be arranged obliquely.

[0036] In this embodiment, the first damping part 12 is arranged in a straight strip shape. In other embodiments, the first damping part 12 can also be arranged in a wavy shape or an irregular curved structure.

[0037] In this embodiment, a plurality of second damping parts 13 on both sides of the first damping part 12 are symmetrically arranged to ensure the force uniformity of the first damping part 12, thereby ensuring the supporting stability of the second damping part 13 for the first damping part 12.

[0038] Among them, the second damping part 13 is integrally formed with the sole body 1. On the one hand, it further ensures the supporting performance of the second damping part 13, and on the other hand, it also ensures the connection stability between the second damping part 13 and the sole body 1.

[0039] Furthermore, the second damping parts 13 corresponding to adjacent first damping parts 12 are arranged staggeredly, so as to improve the distribution uniformity of the second damping parts 13 on the sole body 1, and further ensure the supporting effect of the plurality of second damping parts 13 and the wearing comfort of the shoes made of this sole.

[0040] Embodiment 2

[0041] Refer to Figure 2, The difference between this embodiment and Embodiment 1 is that a plurality of hollow balls 3 are filled in the lightweight cavity 11, and both sides of the hollow balls 3 are respectively abutted against two adjacent second shock-absorbing portions 13. During the wearer's walking, the sole body 1, the first shock-absorbing portion 12 and the second shock-absorbing portion 13 are deformed, and friction is generated between the hollow balls 3 during the deformation process, consuming energy and further improving the shock-absorbing effect.

[0042] Further, a connecting edge 2 is integrally formed on the circumferential side of the sole body 1, and the connecting edge 2 is arranged to surround the sole body 1 in the circumferential direction to facilitate connecting the sole body 1 to the shoe upper.

[0043] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
