Description

Technical Field

[0001] This invention relates to the field of shoe sole technology, specifically to a shoe sole cushioning support structure and shoe sole. Background Technology

[0002] With socio-economic development and the continuous improvement of people's living standards, more and more people are paying attention to health and participating more in sports and fitness in their daily lives. During activities such as running, due to inertia, the sole of the shoe experiences downward pressure from the body's weight and a counter-impact force from the ground (generally equivalent to 3 to 5 times the body weight) at the moment of impact. This impact can easily cause damage to the knee and / or ankle joints. Therefore, shoes are footwear designed to protect the legs and feet from injury, and the cushioning function of shoes is extremely important and necessary.

[0003] Many shoes on the market with cushioning features improve the material or structure of the sole. For example, in terms of sole material, they use foamed thermoplastic polyurethane material with good cushioning effect, and in terms of sole structure, they design air cushions, shock-absorbing columns, and other structures. However, regarding improvements to sole materials, different parts of the sole require different cushioning performance, and soles made of the same material cannot meet these needs. As for improvements to sole structure, there are problems such as an overall stiff structure and low comfort. Summary of the Invention

[0004] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide a sole cushioning support structure and sole that can improve the cushioning effect and wearing comfort of the sole.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Technical Solution 1: A shoe sole cushioning support structure, comprising: a support component having a plurality of support layers arranged in a vertical direction, each support layer having a mutually perpendicular arrangement direction and channel direction, each support layer having a plurality of support channels arranged sequentially along the arrangement direction, each support channel in the same support layer extending along the channel direction; adjacent support layers being interconnected, and their respective arrangement directions and channel directions being mutually perpendicular; a protruding support platform formed by the support layers at the top center of the support component, and a shock-absorbing platform lower than the support platform formed on the periphery of the support platform; and an outer wall covering the outer periphery of the support component to seal the support component and form a sealed air chamber.

[0007] Technical Solution 2, based on Technical Solution 1: The support platform and the shock-absorbing platform are smoothly transitioned by adjusting the height of the corresponding support layer.

[0008] Technical Solution 3 based on Technical Solution 2: In each support layer of the support assembly, the support channel is formed by two opposing sidewalls arranged along the arrangement direction corresponding to the support layer; the sidewalls are periodically arranged with first and second curved sections connected end to end along the channel direction corresponding to the support layer they are located in, and the bending directions of the first and second curved sections are opposite; between two adjacent sidewalls in the same support layer, the positions of their respective first curved sections are staggered, and the positions of their respective second curved sections are also staggered.

[0009] Technical Solution 4 based on Technical Solution 3: In the same support layer, adjacent sidewalls tend to be closer to each other as they approach the junction of adjacent support layers; and at the junction of adjacent support layers, in the same support layer, the starting point of the first curved segment of the sidewall connects with the ending point of the first curved segment of the adjacent sidewall that is offset from it, and the starting point of the second curved segment of the sidewall connects with the ending point of the second curved segment of the adjacent sidewall that is offset from it, so that the support channels in the adjacent support layers are connected.

[0010] Technical Solution 5 based on Technical Solution 4: The starting and ending points of the first and second curved sections in the sidewall are inclined along the extension direction of the corresponding support channel, and the inclination directions of the first and second curved sections in the same sidewall are the same, while the corresponding inclination directions in adjacent sidewalls are opposite.

[0011] Technical Solution Six based on Technical Solution Five: The closer the part of the sidewall is to the junction of the adjacent support layer, the greater its degree of curvature.

[0012] In addition, the present invention also provides a seventh technical solution: a shoe sole that adopts the shoe sole cushioning support structure as described in any one of technical solutions one to six.

[0013] Technical solution eight based on technical solution seven: The sole cushioning support structure is applied to the forefoot of the sole, and the bottom of the support component is an arc extending from front to back, with the arc protruding downward.

[0014] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0015] The sole cushioning support structure provided in technical solution one includes a support component and an outer wall. The outer wall can seal the support component, thereby forming a sealed air chamber inside the support component. The support component comprises several support layers, each with support channels that can hold air. The channels of adjacent support layers are perpendicular to each other, and the adjacent support layers are interconnected. The sealing of the outer wall forms a sealed first air chamber. When the first air cushion is subjected to downward pressure, it is compressed as a whole, thus compressing the air within the support channels. When the pressure is removed, the air returns to its original volume. During this process, the compression and recovery of the air provides a certain degree of shock absorption. Simultaneously, adjacent support layers support each other, and because the support channels of adjacent support layers are interwoven, when… When the first air cushion is compressed, the force is quickly and evenly distributed throughout the entire first air cushion, thus providing better cushioning and rebound performance. Simultaneously, a support platform and a cushioning surface are formed by the support components. The support platform protrudes from the cushioning surface and is the part that directly contacts the foot. When compressed by the foot, the shape of the protruding support platform changes, transferring the force to the bottom and sides. The cushioning surface here receives the force transmitted by the support platform, preventing excessive deformation and maintaining sufficient structural stability for support. Therefore, through the cooperation of the support platform and the cushioning surface, this sole cushioning support structure provides a relatively soft feel while offering good support.

[0016] In technical solution two, the support platform and the damping platform are smoothly transitioned by adjusting the height of the corresponding support layer. When the support platform is under stress, the deformation of the support platform is more moderate, which can better transfer the force to the damping platform.

[0017] In technical solution three, a support channel is formed by the sidewalls. The sidewalls are provided with a first curved section and a second curved section. Compared with straight sidewalls, curved sidewalls have a larger equivalent support area in the arrangement direction. When subjected to downward pressure, the sidewalls themselves can form a certain support, which can then be fed back to the entire support assembly, thereby improving the shock absorption effect of the sole cushioning support structure.

[0018] In technical solution four, adjacent sidewalls tend to be closer together in the same support layer, and there are joints between adjacent sidewalls. The structure of mutual inclination makes the force transmission faster and can make the support performance of the sidewalls better. The joints between adjacent sidewalls can make the joints between adjacent support layers more stable and increase the equivalent contact area of ​​the joints, thereby improving the support performance and improving the overall shock absorption effect.

[0019] In technical solution five, the first and second curved sections are inclined, which makes it easier for adjacent sidewalls to connect into one, and the connection positions are staggered to reduce the impact of excessive stress concentration, thereby improving the overall shock absorption effect.

[0020] In technical solution six, the degree of curvature of the part of the sidewall closer to the support layer is greater, which can make the connection between adjacent sidewalls smoother, avoid sudden structural changes, and enhance the resilience of the support component.

[0021] In technical solution seven, a shoe sole is provided, which adopts the above-mentioned shoe sole cushioning and support structure, thus having good wearing feel and shock absorption and support performance.

[0022] In technical solution eight, the bottom of the support component is made into a downward convex arc shape. When applied to the forefoot part of the sole, it can better conform to the shape of the forefoot and the physiological curvature of the foot, providing users with better foot feel and cushioning support performance.

[0038] This invention provides a sole cushioning support structure that can be applied to the sole as a midsole. This embodiment focuses on the sole cushioning support structure.

[0039] Reference Figure 1 and Figure 2 This illustrates the shape of the sole cushioning support structure provided in this embodiment, with a support platform 21 and a shock-absorbing surface 22 provided on top of the sole cushioning support structure. (See also...) Figure 3 The shoe sole cushioning support structure provided in this embodiment includes a support component 10 and an outer wall 30. Figure 3 The internal structure of the sole cushioning support structure after removing part of the outer wall 30 is shown, wherein the support component 10 is... Figure 3 The bright yellow part in the middle, the outer wall is 30 Figure 3 The yellowish-brown part in the middle, the outer wall 30 covers the outer periphery of the closed support component 10.

[0040] In this embodiment, the sole cushioning support structure is fabricated using 3D printing. The material used can be thermoplastic polyurethane elastomer, which can be commercially available, such as AU brand polyurethane from Dechuang, UT-AU brand polyurethane from Covestro, and BF-brand polyurethane from Lubrizol. Alternatively, nylon can be used, and the material grade can be selected according to actual needs. It should be understood that in this embodiment, when the sole cushioning support structure is made of different materials, its shock absorption performance will inevitably differ, but this difference will not affect the function of the sole cushioning support structure. The materials used for the support component 10 and the outer wall 30 can be the same or different, and the materials used for different parts inside the support component 10 can also be the same or different. However, it should be noted that the outer wall 30 should be made of an airtight material, so that when the outer wall 30 covers and encloses the outer periphery of the support component 10, it can cooperate with the support component 10 to form a sealed air chamber.

[0041] Reference Figures 4 to 7The support assembly 10 has several support layers 11 arranged in the vertical direction. Each support layer 11 has a mutually perpendicular arrangement direction and channel direction. Each support layer 11 has several support channels 12 arranged sequentially along the arrangement direction. Each support channel 12 located in the same support layer 11 extends along the channel direction. Adjacent support layers 11 are interconnected, and their respective arrangement directions and channel directions are mutually perpendicular. A protruding support platform 21 is formed at the top center of the support assembly 10 by the support layer 11, and a shock-absorbing platform 22 lower than the support platform 21 is formed on the periphery of the support platform 21. The outer wall 30 covers the outer periphery of the support assembly 10 to seal the support assembly 10 and form a sealed air chamber.

[0042] Preferably, the support platform 21 and the shock-absorbing platform 22 are smoothly transitioned between each other by adjusting the height of the corresponding support layer 11.

[0043] Furthermore, in each support layer 11 of the support assembly 10, the support channel 12 is formed by two opposing sidewalls 13 arranged along the arrangement direction corresponding to the support layer 11; the sidewalls 13 are periodically arranged with first curved segments 14 and second curved segments 15 connected end to end along the channel direction corresponding to the support layer 11 they are located in, and the bending directions of the first curved segments 14 and the second curved segments 15 are opposite; between two adjacent sidewalls 13 in the same support layer 11, the positions of their respective first curved segments 14 are staggered, and the positions of their respective second curved segments 15 are also staggered.

[0044] In the same support layer 11, adjacent sidewalls 13 tend to be closer to each other as they approach the junction 16 of the adjacent support layer 11; and at the junction 16 of the adjacent support layers 11, in the same support layer 11, the beginning of the first curved segment 14 of the sidewall 13 connects to the end of the first curved segment 14 of the adjacent sidewall 13 that is offset from it, and the beginning of the second curved segment 15 of the sidewall 13 connects to the end of the second curved segment 15 of the adjacent sidewall 13 that is offset from it, so that the support channels 12 in the adjacent support layers 11 are connected.

[0045] The starting and ending points of the first curved section 14 and the second curved section 15 in the side wall 13 are inclined along the extension direction of the corresponding support channel 12, and the inclination directions of the first curved section 14 and the second curved section 15 in the same side wall 13 are the same, while the corresponding inclination directions of adjacent side walls 13 are opposite.

[0046] The greater the curvature of the sidewall 13 is at the junction 16 of the adjacent support layer 11.

[0047] The structure of the support component 10 will be described in detail below.

[0048] Since the sole cushioning support structure provided in this embodiment is manufactured by 3D printing, layer by layer, and its overall structure is built by gradually stacking layers from bottom to top, this embodiment also uses a corresponding layer-by-layer laying method to describe the structure of the support component 10. Among them, Figures 4 to 7 This is a diagram illustrating the different stages of laying the material from bottom to top, following the order of stacking.

[0049] Reference Figure 3 The support component 10 consists of several support layers 11 arranged vertically; see reference. Figure 4 The main body of the support layer 11 is the sidewall 13 used to form the support channel 12, and the space between the two sidewalls 13 is the support channel 12. (Refer to...) Figure 4 ,Will Figure 4 The support layer 11 shown is the first support layer. Although the sidewall 13 has a curved structure, the support channels 12 generally extend in a fixed direction, which is the channel direction of the support layer 11. Simultaneously, the first support layer 11 includes multiple support channels 12, which are arranged in a fixed direction, corresponding to the arrangement direction of the support layer 11. Figure 4 Taking the orientation of the paper as an example, the channel direction of the first layer support layer 11 is left-right, and the arrangement direction is up-down. Furthermore, referring to... Figure 7 The diagram illustrates the structure of a second support layer 11 adjacent to the first support layer 11. In this second support layer 11, the channel direction changes to vertical, and the arrangement direction changes to horizontal. Therefore, it can be seen that the channel direction and arrangement direction of adjacent support layers 11 change periodically. Simultaneously, adjacent support layers 11 are interconnected. When the outer wall 30 seals the entire support assembly 10, the first air cushion portion forms a sealed first air chamber, inside which the aforementioned support layer 11 is disposed.

[0050] Reference Figure 4 and Figure 5 ,by Figure 4 and Figure 5Taking the paper orientation as an example, in the first support layer 11, the sidewalls 13 are periodically arranged with first curved segments 14 and second curved segments 15 connected end-to-end along the left-right direction, that is, the channel direction of the support layer 11. Taking one of the sidewalls 13 as an example, starting from the left end, the first curved segment 14, the second curved segment 15, the first curved segment 14, the second curved segment 15... are arranged sequentially to the right end. The first curved segment 14 starts from the left end and extends smoothly forward and to the right by tilting to the right. The second curved segment 15 starts from the end point of the first curved segment 14 and extends smoothly backward and to the right by tilting to the right. The starting point of the first curved segment 14 and the ending point of the second curved segment 15 are at the same position in the front-back direction. Thus, the sidewalls 13 form a periodic curved structure.

[0051] At the same time, continue to refer to Figure 4 and Figure 5 Taking the aforementioned sidewall 13 as an example, the first curved segments 14 of one adjacent sidewall 13, located below or above it, are offset from each other, and the second curved segments 15 are also offset from each other. This offset means that within the left-right range defined by the start and end points of the first curved segment 14 or the second curved segment 15 of one sidewall 13, the start or end points of the first curved segment 14 or the second curved segment 15 of the other adjacent sidewall 13 are not within that left-right range. In other words, the curved segments on adjacent sidewalls 13 are not perfectly aligned.

[0052] Reference Figure 5 and Figure 6 The sidewalls 13 of the first support layer 11 are gradually laid upwards to form the shape. Figure 5 As can be seen, the starting and ending points of the first curved segment 14 and the second curved segment 15 in the sidewall 13 of the support layer 11 are inclined along the extension direction of the corresponding support channel 12. Furthermore, in the first layer of the support layer 11, the starting and ending points of the first curved segment 14 and the second curved segment 15 of one sidewall 13 are inclined to the left, while the starting and ending points of the first curved segment 14 and the second curved segment 15 of the other sidewall 13 adjacent to this sidewall 13 are inclined to the right. Thus, in the same support layer 11, adjacent sidewalls 13 tend to be closer together as they approach the junction 16 of the adjacent support layer 11. (Refer to...) Figure 6 The first support layer 11 and the second support layer 11 intersect. At this time, the uppermost part of the sidewall 13 of the first support layer 11 begins to connect with the adjacent sidewall 13. The connection point is where the beginning of the first curved segment 14 on the sidewall 13 connects with the end of the first curved segment 14 on the other sidewall 13, and the beginning of the second curved segment 15 on the sidewall 13 connects with the beginning of the second curved segment 15 on the other sidewall 13. Figure 6Taking the paper orientation as an example, at the junction 16, the sidewall 13 of the second support layer 11 begins to extend vertically. Then refer to... Figure 7 The sidewalls 13 of the second support layer 11 gradually extend upwards, and the degree of curvature gradually decreases. The main part of the sidewalls 13 extends in the vertical direction. Subsequently, the sidewalls 13 of the second support layer 11 will gradually lean towards each other until they connect to form a junction 16.

[0053] The structure of the aforementioned support component 10 allows the outer wall 30 to form a sealed air chamber inside the support component 10 after it is closed. The support component 10 is provided with several support layers 11, each with a support channel 12 that can accommodate air. The channel directions of the support channels 12 of adjacent support layers 11 are perpendicular to each other, and adjacent support layers 11 are interconnected. The sealing of the outer wall 30 forms a sealed first air chamber. When the first air cushion is subjected to downward pressure, the first air cushion acts as a whole... The body is compressed, which compresses the air in the support channel 12. When the pressure is removed, the air will return to its original volume. In this process, the compression and recovery of the air can play a certain role in shock absorption. At the same time, the adjacent support layers 11 will support each other. Since the support channels 12 of the adjacent support layers 11 are intertwined, when the first air cushion is compressed, the force will be quickly and evenly distributed to the entire first air cushion, thereby providing a better shock absorption effect through the entire first air cushion and also having better rebound performance.

[0054] Reference Figure 1 and Figure 2 At the top of the support component 10, a support platform 21 is formed in the middle by setting the laying position of the support layer 11. In this embodiment, there is one support platform 21, and it matches the outer contour of the support component 10. A shock-absorbing platform 22 is formed in the part between the support platform 21 and the outer contour of the support component 10. It should be understood that the support platform 21 is formed by the support layer 11. Since each support layer 11 of the support component 10 is laid layer by layer by 3D printing, when laying to the top position of the support component 10, the support layer 11 can be laid only in the middle part where the support platform 21 needs to be formed, while the laying of the shock-absorbing platform 22 is stopped, thereby forming the aforementioned support platform 21 and shock-absorbing platform 22. At the same time, referring to Figure 1 and Figure 2In the transition section between the support platform 21 and the damping platform 22, the height of the corresponding support layer 11 is adjusted to make the transition between the two smooth. The adjustment of the height of the corresponding support layer 11 refers to the height of the support layer 11 between the support platform 21 and the damping platform 22 gradually decreasing from the support platform 21 toward the damping platform 22, so that the top surface of the support platform 21 can smoothly transition to the damping platform 22.

[0055] The support component 10 forms a support platform 21 and a cushioning surface 22. The support platform 21 protrudes from the cushioning surface 22 and is the part that directly contacts the foot. When the support platform 21 is compressed by the foot, its shape changes, thereby transferring the force to the bottom and sides. The cushioning surface 22 receives the force transmitted by the support platform 21, preventing the support platform 21 from deforming too drastically and maintaining sufficient structural stability for support. Therefore, through the cooperation of the support platform 21 and the cushioning surface 22, the sole cushioning support structure can provide a relatively soft feel while having a good support effect.

[0056] In addition, the present invention provides another embodiment, which is a shoe sole. The shoe sole adopts the above-mentioned shoe sole cushioning and support structure, thus having better wearing comfort and shock absorption and support performance.

[0057] Specifically, the forefoot portion of the midsole of this shoe sole employs the cushioning support structure provided in the above embodiment. The arch and heel portions of the midsole can be made of other materials, or the entire midsole can utilize components similar to the aforementioned cushioning support structure. The bottom of the support component 10 is an arc extending from front to back, and this arc bulges downwards. Through this downwardly bulging arc-shaped bottom, when the cushioning support structure is applied to the forefoot portion of the midsole, it can better conform to the shape of the forefoot pad and the physiological curvature of the foot. It should be noted that the external shape of the cushioning support structure needs to be modified and adjusted accordingly for the arch and heel portions.

[0058] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this invention, but does not constitute a limitation on the scope of protection of this invention. Modifications, equivalent substitutions, or other improvements to the embodiments of this invention or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this invention or the foregoing embodiments, in conjunction with common knowledge, general technical knowledge, and / or existing technology, should all be included within the scope of protection of this invention.
