Description

Technical Field

[0001] The utility model relates to the technical field of soles, in particular to a sole protection and shock absorbing structure and a sole. Background Art

[0002] With the development of social economy and the continuous improvement of people's material level, more and more people pay attention to health and participate more in sports and fitness in daily life. In particular, during running and other sports, due to the effect of inertia, when the sole of the athlete's shoe touches the ground, the sole will be subjected to the downward pressure exerted by the body's own gravity on the sole, and the anti-impact force exerted by the bottom surface (generally equivalent to 3 to 5 times the body weight), which can easily cause certain damage to the athlete's knee joints and / or ankle joints and other human structures. Therefore, shoes are foot products that protect the legs and feet from injury, and the cushioning function of shoes is very important and necessary.

[0003] Many shoes with shock-absorbing function on the market are improved in the material or structure of the soles. For example, the sole material uses foamed thermoplastic polyurethane material with good shock-absorbing effect, and the sole structure uses air cushions, shock-absorbing columns and other structures. However, for the improvement of the sole material, the shock-absorbing performance required at different positions of the sole is different, and the sole made of the same material cannot meet this demand; for the improvement of the sole structure, there are problems such as the overall structure being too hard and low comfort. Utility Model Content

[0004] The purpose of the utility model is to overcome the above-mentioned defects or problems existing in the background technology and to provide a sole protection and shock absorbing structure and a sole, which can improve the protection and shock absorbing performance of the sole.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] Technical solution 1: A sole protection and shock-absorbing structure, comprising: a support assembly, comprising a first support part and at least one second support part, the second support part is located in the first support part and separated by a partition wall, and the second support part protrudes from the top of the first support part; the first support part and the second support part are both arranged with a plurality of support layers along the up and down directions, and each of the support layers is defined with mutually perpendicular arrangement directions and channel directions, each of the support layers is provided with a plurality of support channels arranged in sequence along the arrangement direction, and each of the support channels located in the same support layer extends along the channel direction; adjacent support layers are interconnected, and their respective corresponding arrangement directions are perpendicular to each other, and the channel directions are also perpendicular to each other; the size of the support channel of the support layer in the first support part is larger than the size of the support channel of the support layer in the second support part; an outer wall, which covers the periphery of the support assembly to close the first support part and the second support part and form a closed first air chamber and a second air chamber respectively.

[0007] Technical solution 2 based on technical solution 1: a protruding support platform is formed by the support layer at the top middle position of the support assembly, and a shock-absorbing table surface lower than the support platform is formed on the peripheral side of the support platform; the second support part protrudes from the support platform to form an air cushion protrusion.

[0008] Technical solution three based on technical solution two: the support platform and the shock-absorbing tabletop are smoothly transitioned between the two by adjusting the heights of the corresponding support layers.

[0009] Technical solution four based on technical solution three: in each supporting layer of the supporting assembly, the supporting channel is formed by cooperation of two opposite side walls arranged along the arrangement direction corresponding to the supporting layer; the side walls are periodically arranged with a first curved segment and a second curved segment connected end to end along the channel direction corresponding to the supporting layer in which they are located, and the bending directions of the first curved segment and the second curved segment are opposite; between two adjacent side walls in the same supporting layer, the positions of their respective first curved segments are staggered, and the positions of their respective second curved segments are also staggered.

[0010] Technical solution five based on technical solution four: in the same supporting layer, adjacent side walls have a tendency to lean closer to each other as they are closer to the junction of adjacent supporting layers; and at the junction of adjacent supporting layers, in the same supporting layer, the starting point of the first curved section of the side wall is connected to the end point of the first curved section of the other adjacent side wall that is staggered therewith, and the starting point of the second curved section of the side wall is connected to the end point of the second curved section of the other adjacent side wall that is staggered therewith, so that the support channels in adjacent supporting layers are connected.

[0011] Technical solution six based on technical solution five: the starting points and end points of the first curved section and the second curved section in the side wall are inclined along the extension direction of the corresponding support channel, and the corresponding inclination directions of the first curved section and the second curved section in the same side wall are the same, and the corresponding inclination directions in adjacent side walls are opposite.

[0012] Technical solution seven based on technical solution six: In the support assembly, the distances along the channel direction at the first curved section, the starting point and the end point of the second curved section of the side wall of the support layer in the first support part are greater than the distances along the channel direction at the first curved section, the starting point and the end point of the second curved section of the side wall of the support layer in the second support part.

[0013] Technical solution eight based on technical solution seven: the closer the side wall is to the junction of adjacent support layers, the greater its curvature.

[0014] In addition, the utility model also provides technical solution nine: a sole, which adopts the sole protection and shock-absorbing structure as described in any one of technical solutions one to eight.

[0015] From the above description of the utility model, it can be seen that compared with the prior art, the utility model has the following beneficial effects:

[0016] In the sole protection and shock-absorbing structure provided by Technical Solution 1, a support component and an outer wall are provided, and the outer wall can close the support component to form a closed air chamber inside the support component; a first support part and a second support part are provided in the support component, both of which include a plurality of support layers, and the support layers are provided with support channels, which can accommodate air, and at the same time, the channel directions of the support channels of adjacent support layers are perpendicular to each other, and the adjacent support layers are interconnected, and a closed first air chamber is formed by closing the outer wall; when the support component is subjected to downward pressure, the support component is squeezed as a whole, so that the air in the support channel is compressed, and when the pressure is removed, the air will restore its original volume. In this process, the compression and recovery of the air can play a certain shock-absorbing role. At the same time, adjacent support layers will support each other, and because the support channels of adjacent support layers are in a staggered form, when the support component is squeezed, the force received will be quickly and evenly dispersed to the entire The second support part is arranged in the first support part and separated by a partition wall, and the size of the support channel of the support layer in the first support part is larger than the size of the support channel of the support layer in the second support part. The size difference of the support channel makes the first support part lower in hardness than the second support part, and the second support part is arranged to protrude from the top of the first support part. Therefore, when the user steps on the sole protection and shock-absorbing structure, the user's sole first applies force to the second support part, and the second support part sinks to cause the first support part to deform, thereby dispersing the pressure of the foot on the support component. At the same time, since the user's sole first contacts the harder second support part, it can be supported by the second support part, thereby improving the overall support effect and stability of the support component; then the user's sole contacts the first support part, and the first support part deforms to provide better shock-absorbing and rebound.

[0017] In the second technical solution, a support platform and a shock-absorbing surface are formed by a support component, the support platform protrudes from the shock-absorbing surface, and the support platform is the part that directly contacts the foot; when the protruding support platform is squeezed by the foot, its shape will change, thereby transferring the force to the bottom and sides, and the shock-absorbing surface plays the role of receiving the force transmitted by the support platform, so that the support platform will not deform too drastically, thereby enabling the support platform to maintain sufficient structural stability for support; therefore, through the cooperation of the support platform and the shock-absorbing surface, the sole protection and shock-absorbing structure can provide a softer foot feel while having a better support effect; and, the second support part is protruded on the support platform to form an air cushion protrusion, and the air cushion protrusion can make the second support part cooperate with the shape of the support platform to better disperse the pressure to the entire first support part.

[0018] In technical solution three, the support platform and the shock-absorbing surface are smoothly transitioned by adjusting the height of the corresponding support layer. When the support platform is subjected to force, the deformation of the support platform is more moderate, and the force can be better transmitted to the shock-absorbing surface.

[0019] In technical solution four, a support channel is formed by the cooperation of the side walls, and a first curved section and a second curved section are provided on the side walls. Compared with the straight side walls, the curved side walls have a larger equivalent support area in the arrangement direction. When subjected to downward pressure, the side walls themselves can form a certain support, which can then be fed back to the entire support assembly, thereby improving the shock-absorbing effect of the sole protective shock-absorbing structure.

[0020] In technical solution five, in the same supporting layer, adjacent side walls have a tendency to lean closer, and there are connected parts between adjacent side walls. The mutually leaning structure makes the force transmission faster and can make the supporting performance of the side walls better. The adjacent side walls are connected, which can make the connecting parts between adjacent supporting layers more stable and increase the equivalent contact area of ​​the connecting parts, thereby improving the supporting performance and thus improving the overall shock absorbing effect.

[0021] In technical solution six, the first curved section and the second curved section are inclined, which can make it easier for adjacent side walls to be connected as a whole, and the connecting positions are staggered, reducing the impact of excessive stress concentration, thereby improving the overall shock-absorbing effect.

[0022] In Technical Solution Seven, the size of the curved section in the support layer in the first support part is larger than the size of the curved section in the support layer in the second support part. Therefore, the density of the curved section in the support layer of the second support part is greater than the support layer above the partition layer. As a result, the overall hardness of the support layer of the second support part is higher and can have better supporting performance, while the overall hardness of the support layer of the first support part is lower and can provide better shock absorption and rebound.

[0023] In technical solution eight, the curvature of the side wall closer to the support layer is increased, so that the connection between adjacent side walls can be smoother, sudden changes in the structure can be avoided, and the resilience of the support assembly can be enhanced.

[0024] In technical solution nine, a sole is provided, which adopts the above-mentioned sole protection and shock-absorbing structure, so it has good shock-absorbing and supporting performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The embodiment of the utility model provides a sole protection and shock absorbing structure, which can be applied to the sole and used as the midsole of the sole. This embodiment is described with the sole protection and shock absorbing structure as the main body.

[0040] Reference Figure 1 , which shows the appearance of the sole protection and shock absorbing structure provided in this embodiment, and a protruding air cushion protrusion 23 is arranged on the top of the sole protection and shock absorbing structure. Figure 2 The sole protection and shock absorbing structure provided in this embodiment includes a support component 10 and an outer wall 30. Figure 2 The internal structure of the sole protection and shock absorbing structure is shown after removing part of the outer wall 30, wherein the support assembly 10 is Figure 2 The bright yellow part in the outer wall 30 is Figure 2 The outer wall 30 covers the periphery of the closed support assembly 10, which is the khaki part in the figure.

[0041] In this embodiment, the sole protection and shock absorbing structure is prepared by 3D printing, and the material used can be a thermoplastic polyurethane elastomer, and the thermoplastic polyurethane elastomer material can be selected from commercially available products, such as Dechuang AU brand polyurethane material, Covestro UT-AU brand polyurethane material and Lubrizol BF- brand polyurethane material. Alternatively, the material used can also be nylon, and the material brand can be selected according to actual needs. It should be understood that in this embodiment, when the sole protection and shock absorbing structure is made of different materials, its shock absorbing performance will inevitably be different, but this difference will not affect the sole protection and shock absorbing structure to achieve its function. Among them, the materials used in the support assembly 10 and the outer wall 30 can be the same or different, and the materials used in different parts of the support assembly 10 can be the same or different. However, it should be noted that the outer wall 30 should be made of an airtight material, and when the outer wall 30 covers the periphery of the closed support assembly 10, it can cooperate with the support assembly 10 to form a closed air chamber.

[0042] Reference Figure 2 The support assembly 10 includes a first support portion 11 and at least one second support portion 12, wherein the second support portion 12 is located in the first support portion 11 and is separated by a partition wall 13, and the second support portion 12 protrudes from the top of the first support portion 11; wherein the first support portion 11 and the second support portion 12 are both arranged with a plurality of support layers 14 in the up-down direction, and each of the support layers 14 is defined with mutually perpendicular arrangement directions and channel directions, and each of the support layers 14 is provided with a plurality of support channels 15 arranged in sequence along the arrangement direction, and each of the support channels 15 located in the same support layer 14 extends along the channel direction; adjacent support layers 14 are interconnected, and their corresponding arrangement directions are mutually perpendicular, and the channel directions are also mutually perpendicular. Moreover, the size of the support channel 15 of the support layer 14 in the first support portion 11 is greater than the size of the support channel 15 of the support layer 14 in the second support portion 12. The outer wall 30 covers the outer circumference of the support assembly 10 to close the first support portion 11 and the second support portion 12 and form a sealed first air chamber and a sealed second air chamber respectively.

[0043] Preferably, the support layer 14 forms a protruding support platform 21 at the middle position of the top of the support assembly 10, and a shock absorbing table 22 lower than the support platform 21 is formed on the peripheral side of the support platform 21; the second support portion 12 protrudes from the support platform 21 to form an air cushion protrusion 23. Moreover, the support platform 21 and the shock absorbing table 22 are smoothly transitioned by adjusting the height of the corresponding support layer 14.

[0044] In addition, in each supporting layer 14 of the supporting assembly 10, the supporting channel 15 is formed by two opposite side walls 16 arranged along the arrangement direction corresponding to the supporting layer 14; the side walls 16 are periodically arranged with a first curved segment 17 and a second curved segment 18 connected end to end along the channel direction corresponding to the supporting layer 14 where they are located, and the bending directions of the first curved segment 17 and the second curved segment 18 are opposite; between the two adjacent side walls 16 in the same supporting layer 14, the positions of the respective first curved segments 17 are staggered, and the positions of the respective second curved segments 18 are also staggered.

[0045] In the same supporting layer 14, the adjacent side walls 16 have a tendency to lean closer to each other as they approach the joint 19 of the adjacent supporting layers 14; and at the joint 19 of the adjacent supporting layers 14, in the same supporting layer 14, the starting point of the first curved section 17 of the side wall 16 is connected to the end point of the first curved section 17 of the other adjacent side wall 16 that is staggered therewith, and the starting point of the second curved section 18 of the side wall 16 is connected to the end point of the second curved section 18 of the other adjacent side wall 16 that is staggered therewith, so that the support channels 15 in the adjacent supporting layers 14 are connected.

[0046] The starting points and end points of the first curved section 17 and the second curved section 18 in the side wall 16 are inclined along the extension direction of the corresponding support channel 15, and the corresponding inclination directions of the first curved section 17 and the second curved section 18 in the same side wall 16 are the same, and the corresponding inclination directions in adjacent side walls 16 are opposite.

[0047] In the support assembly 10, the distances along the channel direction between the first curved segment 17 and the starting point and the end point of the second curved segment 18 of the side wall 16 of the support layer 14 in the first support portion 11 are greater than the distances along the channel direction between the first curved segment 17 and the starting point and the end point of the second curved segment 18 of the side wall 16 of the support layer 14 in the second support portion 12.

[0048] The closer the side wall 16 is to the joint 19 of the adjacent support layers 14 , the greater the curvature thereof.

[0049] The structure of the support assembly 10 is described in detail below.

[0050] Since the sole protection and shock-absorbing structure provided in this embodiment is made by stacking and printing layer by layer using 3D printing, and the overall structure is gradually stacked layer by layer from bottom to top to achieve structural construction, this embodiment also uses a corresponding layer-by-layer laying method to illustrate the structure of the support assembly 10. Figures 3 to 6 Illustrations of the different stages of laying from the bottom up in the order of laying and stacking.

[0051] Reference Figure 2 In this embodiment, the second support portion 12 is provided with a portion located in the first support portion 11 and close to the edge of the support platform 21. Figure 1 The second support portion 12 protrudes from the top of the support platform 21 to form an air cushion protrusion 23. Figure 2 In the support assembly 10, the first support part 11 and the second support part 12 are both composed of a plurality of support layers 14 arranged up and down. The structures of the support layers 14 constituting the first support part 11 and the second support part 12 are similar. Therefore, in this embodiment, the support layer 14 of the first support part 11 is taken as an example for description.

[0052] Reference Figure 3 The main body of the support layer 14 is a side wall 16 for forming a support channel 15, and the space between the two side walls 16 is the support channel 15. Figure 3 ,Will Figure 3 The support layer 14 shown is a first-layer support layer 14. Although the side wall 16 has a curved structure, the support channel 15 generally extends in a fixed direction, which is the channel direction of the support layer 14. At the same time, the first-layer support layer 14 includes a plurality of support channels 15, which are arranged along a fixed direction, which is the corresponding arrangement direction of the support layer 14. Figure 3 Taking the paper direction as an example, the channel direction of the first layer of the support layer 14 is the left-right direction, and the arrangement direction is the up-down direction. Figure 6 , which shows the structure of the second layer of support layer 14 adjacent to the first layer of support layer 14. In the second layer of support layer 14, the channel direction becomes the up-down direction, and the arrangement direction becomes the left-right direction. It can be seen that for adjacent support layers 14, the channel direction and arrangement direction are periodically changed. At the same time, the adjacent support layers 14 are interconnected. When the outer wall 30 closes the entire support assembly 10, the first support portion 11 as a whole forms a closed first air chamber, and the above-mentioned support layer 14 is arranged inside the first air chamber.

[0053] Reference Figure 3 and Figure 4 ,by Figure 3 and Figure 4Taking the paper direction of as an example, in the first support layer 14, the side wall 16 is periodically arranged with the first curved segment 17 and the second curved segment 18 connected end to end along the left-right direction, that is, the channel direction of the support layer 14. Taking one of the side walls 16 as an example, starting from the left end, the first curved segment 17, the second curved segment 18, the first curved segment 17, the second curved segment 18, etc. are arranged in sequence to the rightmost end, wherein the first curved segment 17 starts from the left end and extends smoothly to the right and forward, and the second curved segment 18 starts from the end point of the first curved segment 17, and extends smoothly to the right and backward, and the starting point of the first curved segment 17 and the end point of the second curved segment 18 are at the same position in the front-to-back direction. Thus, the side wall 16 forms a periodic curved structure.

[0054] Meanwhile, continue to refer to Figure 3 and Figure 4 Taking the side wall 16 mentioned above as an example, the positions of the first curved sections 17 of the other side wall 16 below or above the side wall 16 and adjacent to the side wall 16 are staggered, and the positions of the second curved sections 18 of the two side walls are also staggered. The staggered here means that within the left-right range defined by the starting point and the end point of the first curved section 17 or the second curved section 18 of one side wall 16, the starting point or the end point of the first curved section 17 or the second curved section 18 of the other side wall 16 adjacent to the side wall 16 is not within the left-right range. In other words, the curved sections on the adjacent side walls 16 are not completely opposite.

[0055] Reference Figure 4 and Figure 5 The side walls 16 of the first supporting layer 14 are gradually laid upwards to form a shape. Figure 4 It can be seen that the starting and ending points of the first curved section 17 and the second curved section 18 in the side wall 16 of the support layer 14 are inclined along the extension direction of the corresponding support channel 15, and in the first layer of the support layer 14, the starting and ending points of the first curved section 17 and the second curved section 18 of one side wall 16 are inclined toward the left, and the starting and ending points of the first curved section 17 and the second curved section 18 of the other side wall 16 adjacent to the side wall 16 are inclined toward the right. In this way, in the same support layer 14, adjacent side walls 16 have a tendency to be closer to each other as they are closer to the joint 19 of the adjacent support layer 14. Figure 5 , the first support layer 14 and the second support layer 14 intersect, and at this time, the top of the side wall 16 of the first support layer 14 begins to connect with the adjacent side wall 16, and the connecting position is that the starting point of the first curved section 17 on the side wall 16 connects with the end point of the first curved section 17 on the other side wall 16, and the starting point of the second curved section 18 on the side wall 16 connects with the starting point of the second curved section 18 on the other side wall 16. Figure 5Taking the paper direction of FIG. 1 as an example, at the position of the joint 19, the side wall 16 of the second support layer 14 begins to extend in the vertical direction. Figure 6 The side walls 16 of the second support layer 14 gradually extend upward, and the curvature gradually decreases, and the main part of the side walls 16 extends in the vertical direction. Afterwards, the side walls 16 of the second support layer 14 gradually lean toward each other until they are connected to form a joint 19.

[0056] Reference Figure 2 A partition wall 13 is provided between the first support portion 11 and the second support portion 12 in the support assembly 10. The partition wall 13 can be made of the same material as the outer wall 30 or the same material as the support assembly 10. Its main purpose is to separate the first support portion 11 from the second support portion 12. After the outer wall 30 covers the support assembly 10, a sealed first air chamber is formed in the first support portion 11, and a sealed second air chamber is formed in the second support portion 12. The first air chamber and the second air chamber are separated by the partition wall 13. Therefore, the material of the partition wall 13 should also be airtight.

[0057] The second support portion 12 is also provided with a plurality of support layers 14. The difference from the first support portion 11 is that the support channels 15 of the support layers 14 of the second support portion 12 are smaller in size. Figures 3 to 6 , the distances along the channel direction between the first curved section 17 and the starting and ending points of the second curved section 18 of the side wall 16 of the support layer 14 of the first support portion 11 are greater than the distances along the channel direction between the first curved section 17 and the starting and ending points of the second curved section 18 of the side wall 16 of the support layer 14 of the second support portion 12, so that the density of the support layer 14 of the first support portion 11 is smaller, the overall hardness of the first support portion 11 is lower, and the rebound and shock absorption performance are better, while the density of the support layer 14 located in the second support portion 12 is greater, and a higher hardness can be provided through a denser structure, thereby improving better support and protection performance. Among them, the distances along the channel direction between the starting and ending points of the first curved section 17 and the second curved section 18 refer to the entire distance calculated from the starting point of the first curved section 17, along the channel direction of the support layer 14, until reaching the end point of the second curved section 18. It should be noted that, since the side wall 16 has a tendency to tilt, this distance can be obtained by measuring the side wall 16 at different heights and taking the average value.

[0058] Reference Figure 1, at the top of the support component 10, by setting the laying position of the support layer 14, a support platform 21 is formed in the middle position. In the present embodiment, there is only one support platform 21, and it matches the outer contour of the support component 10, and a shock-absorbing table 22 is formed in the portion 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 14. Since each support layer 14 of the support component 10 is laid layer by layer by 3D printing, when it is laid to the top position of the support component 10, the support layer 14 can continue to be laid only in the middle portion where the support platform 21 needs to be formed, and the laying of the shock-absorbing table 22 is stopped, thereby forming the above-mentioned support platform 21 and shock-absorbing table 22. At the same time, referring to Figure 1 and Figure 2 In the transition portion between the support platform 21 and the shock-absorbing table surface 22, a smooth transition is achieved by adjusting the height of the corresponding support layer 14. The adjustment of the height of the corresponding support layer 14 referred to here refers to the height of the support layer 14 in the portion between the support platform 21 and the shock-absorbing table surface 22, which gradually decreases from the support platform 21 toward the shock-absorbing table surface 22, so that the top surface of the support platform 21 can smoothly transition to the shock-absorbing table surface 22. A support platform 21 and a shock-absorbing surface 22 are formed by the support component 10, wherein the support platform 21 protrudes from the shock-absorbing surface 22, and the support platform 21 is the portion that directly contacts the foot; when the protruding support platform 21 is squeezed by the foot, its shape will change, thereby transferring the force to the bottom and sides, and the shock-absorbing surface 22 plays the role of receiving the force transmitted by the support platform 21, so that the support platform 21 will not deform too drastically, thereby allowing the support platform 21 to maintain sufficient structural stability for support; therefore, through the cooperation of the support platform 21 and the shock-absorbing surface 22, the sole protection and shock-absorbing structure can provide a softer foot feel while having a better support effect.

[0059] Reference Figure 1 The second support portion 12 protrudes from the support platform 21 to form an air cushion protrusion 23 . The air cushion protrusion 23 enables the second support portion 12 to cooperate with the shape of the support platform 21 , thereby better dispersing the pressure to the entire first support portion 11 .

[0060] In the sole protection and shock absorbing structure provided by the utility model, a support assembly 10 and an outer wall 30 are provided. The outer wall 30 can close the support assembly 10, so that a closed air chamber is formed inside the support assembly 10; a first support part 11 and a second support part 12 are provided in the support assembly 10, both of which include a plurality of support layers 14, and the support layers 14 are provided with support channels 15, and the support channels 15 can accommodate air. At the same time, the channel directions of the support channels 15 of adjacent support layers 14 are perpendicular to each other, and the adjacent support layers 14 are connected to each other through the outer wall 30. The support assembly 10 is sealed to form a sealed first air chamber; when the support assembly 10 is subjected to downward pressure, the support assembly 10 is squeezed as a whole, so that the air in the support channel 15 is compressed. When the pressure is removed, the air will restore its original volume. In this process, the compression and recovery of the air can play a certain shock-absorbing role. At the same time, the adjacent support layers 14 support each other, and because the support channels 15 of the adjacent support layers 14 are intertwined, when the support assembly 10 is squeezed, the force received will be quickly and evenly dispersed to the entire support. The second support portion 12 is disposed in the first support portion 11 and separated by the partition wall 13, and the size of the support channel 15 of the support layer 14 in the first support portion 11 is larger than the size of the support channel 15 of the support layer 14 in the second support portion 12. The size difference of the support channel 15 makes the first support portion 11 lower in hardness than the second support portion 12, and the second support portion 12 protrudes from the first support portion 11. The top is arranged, so when the user steps on the sole protection and shock-absorbing structure, the user's sole first applies force to the second support part 12, and the second support part 12 sinks to cause the first support part 11 to deform, thereby dispersing the pressure of the foot on the support assembly 10. At the same time, because the user's sole first contacts the harder second support part 12, it can be supported by the second support part 12, thereby improving the overall support effect and stability of the support assembly 10; then the user's sole contacts the first support part 11, and the first support part 11 deforms to provide better shock absorption and rebound.

[0061] In addition, the utility model also provides another embodiment, which is a sole, and the sole adopts the above-mentioned sole protection and shock-absorbing structure, so it has a good wearing feeling and shock-absorbing support performance. Specifically, the forefoot part, arch part and heel part of the midsole of the sole can adopt the sole protection and shock-absorbing structure provided by the above embodiment, or only some of them can adopt the sole protection and shock-absorbing structure provided by the above embodiment.

[0062] The description of the above specification and embodiments is used to explain the protection scope of the utility model, but does not constitute a limitation on the protection scope of the utility model. Through the enlightenment of the utility model or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent replacements or other improvements to the embodiments of the utility model or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the utility model.
