Description

Technical Field

[0001] The utility model relates to the technical field of soles, in particular to a sole rebound boosting 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 is designed with air cushions, shock-absorbing columns and other structures. However, based on shock absorption, the existing shoes cannot provide a boosting effect for users' running, jumping and other actions, and the functionality is relatively single. 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 rebound boosting structure and a sole, which can provide a boosting function for the sole.

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

[0006] Technical solution 1: A sole rebound boosting structure, comprising: an upper covering layer, a lower covering layer, a side covering layer and a support assembly; the support assembly is arranged with a plurality of support layers along the up-down direction, the support layers located at the uppermost layer and the lowermost layer are respectively closed by the upper covering layer and the lower covering layer, and the side covering layer closes the four sides of the support assembly; for each of the support layers, mutually perpendicular arrangement directions and channel directions are defined, 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 corresponding arrangement directions are perpendicular to each other, and the channel directions are also perpendicular to each other; in the support assembly, a partition layer is provided between two adjacent support layers, the partition layer isolates the support layers on the upper and lower sides thereof, and the size of the support channel of the support layer located below the partition layer is smaller than the size of the support channel of the support layer located above the partition layer.

[0007] Technical solution 2 based on technical solution 1: the support component protrudes upward at the middle position of its top to form a support platform, and a shock-absorbing table surface is formed around the support platform; the support platform and the shock-absorbing table surface are both enclosed by the upper covering layer and are both located above the partition layer.

[0008] Technical solution three based on technical solution two: 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.

[0009] Technical solution four based on technical solution three: in the same supporting layer, the adjacent side walls have a tendency to lean closer to each other as they are closer to the junction of the 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 the adjacent supporting layers are connected.

[0010] Technical solution five based on technical solution four: 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.

[0011] Technical solution six based on technical solution five: In the supporting 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 supporting layer located above the partition layer are smaller 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 supporting layer located below the partition layer.

[0012] Technical solution seven based on technical solution six: the closer the side wall is to the junction of adjacent support layers, the greater its curvature.

[0013] In addition, the utility model also provides technical solution eight: a sole, which adopts the sole rebound boosting structure as described in any one of technical solutions one to seven.

[0014] Technical solution nine based on technical solution eight: the sole rebound boosting structure is applied to the forefoot of the sole, and the bottom of the support component is in the shape of an arc extending from front to back, and the arc protrudes downward.

[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 rebound boosting structure provided by the technical solution 1, an upper covering layer, a lower covering layer, a side floating layer and a support component are provided. The support component is provided with a support layer, and the upper covering layer, the lower covering layer and the side floating layer surround the support component from top to bottom and on all sides, so that the support component forms a sealed structure; the support layer in the support component is provided with a support channel, and the support channel can accommodate air. 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; when the upper covering layer is subjected to downward pressure, the support component as a whole will be squeezed, 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 role. The support components of the present invention can achieve a certain shock-absorbing effect. At the same time, the adjacent support layers will support each other, and because the support channels of the 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 support component, thereby providing a better shock-absorbing effect through the entire support component; and a partition is arranged in the middle position of the support component in the up and down directions, and the partition divides the entire support component into two mutually isolated parts, and each isolated part independently compresses and releases the air inside it, and the partition itself will play a role in pulling the support layer in the horizontal direction, so that the support performance of the support layer will be improved, and the impact energy can be better absorbed;

[0017] In addition, the size of the support channel below the partition is smaller than that of the support channel above the partition, so that the support layer above the partition can have a lower hardness, better fit the shape of the foot when worn, and provide a better foot feel; the partition arranged in the middle not only plays an insulating role, but also can improve the overall rigidity of the sole rebound boosting structure, increase the bending moment of the sole, and provide better rebound performance in the process of recovering deformation after being squeezed, while providing a boosting effect for the user's movements through its own deformation; the support layer below the partition has a higher hardness, which can effectively improve the support performance of the sole.

[0018] 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. 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 maintaining sufficient structural stability for the support platform to provide support. Therefore, through the cooperation of the support platform and the shock-absorbing surface, the sole rebound boosting structure can provide a softer foot feel while having a better support effect.

[0019] In technical solution three, 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 rebound boosting structure.

[0020] In technical solution four, 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 five, 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 six, the size of the curved section in the support layer below the interlayer is smaller than the size of the curved section in the support layer above the interlayer. Therefore, the density of the curved section in the support layer below the interlayer is greater than that of the support layer above the interlayer. As a result, the overall hardness of the support layer below the interlayer is higher and has better supporting performance, while the overall hardness of the support layer above the interlayer is lower and can provide a better foot feel.

[0023] In technical solution seven, the curvature of the side wall closer to the support layer is made greater, 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 eight, a sole is provided, which adopts the above-mentioned sole rebound boosting structure, so it has better wearing feel and shock-absorbing support performance.

[0025] In technical solution nine, the bottom of the support component is made to be in the shape of a downward convex arc. When applied to the forefoot part of the sole, it can better fit the shape of the forefoot and the physiological curvature of the foot, providing users with better foot feel and shock-absorbing support performance.

[0041] The present invention provides a sole rebound boosting structure, which can be applied to a sole and used as a midsole of the sole. This embodiment is described with the sole rebound boosting structure as the main body.

[0042] Reference Figure 1 The sole rebound boosting structure provided in this embodiment includes an upper covering layer 10, a lower covering layer 20, and a side covering layer 30. Figure 2 After removing the upper cover layer 10, it can be observed that the sole rebound boosting structure also includes a support assembly 40, which includes a plurality of support layers and a spacer 44. The support layer is Figures 2 to 7 The yellow part of the

[0043] In this embodiment, the sole rebound boosting structure is prepared by 3D printing, and the material used can be 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 rebound boosting structure is made of different materials, its shock absorbing performance will inevitably be different, but this difference will not affect the sole rebound boosting structure to achieve its function. In addition, the materials used in the upper cover 10, the lower cover 20, the side cover 30 and the support assembly 40 can be the same or different, for example, the upper cover 10 uses a material with higher elasticity, and the lower cover 20 uses a material with higher hardness; at the same time, the material of the support assembly 40 can also be different from the upper cover 10 and the lower cover 20, which will not affect the function of the sole rebound boosting structure. However, it should be noted that the upper covering layer 10, the lower covering layer 20 and the side covering layer 30 should be made of airtight materials, and when they cover the upper side, the lower side and the surrounding side of the support assembly 40, they can cooperate with the support assembly 40 to form a closed air chamber.

[0044] Among them, the support assembly 40 is provided with several support layers along the up-down direction, the support layers at the top and bottom are respectively closed by the upper covering layer 10 and the lower covering layer 20, and the side covering layer 30 closes the surrounding of the support assembly 40; for each support layer, mutually perpendicular arrangement directions and channel directions are defined, and each support layer is provided with several support channels 41 arranged in sequence along the arrangement direction, and each support channel 41 located in the same support layer extends along the channel direction; adjacent support layers are interconnected, and their corresponding arrangement directions are mutually perpendicular, and the channel directions are also mutually perpendicular. In addition, in the support assembly 40, there is provided a partition layer 44 located between two adjacent support layers, the partition layer 44 isolates the support layers on the upper and lower sides thereof, and the size of the support channel 41 of the support layer below the partition layer 44 is smaller than the size of the support channel 41 of the support layer above the partition layer 44.

[0045] Preferably, in each supporting layer of the supporting assembly 40, the supporting channel 41 is formed by cooperation of two opposite side walls 42 arranged along the arrangement direction corresponding to the supporting layer; the side walls 42 are periodically arranged with a first curved segment 421 and a second curved segment 422 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 421 and the second curved segment 422 are opposite; between adjacent side walls 42 in the same supporting layer, the positions of the respective first curved segments 421 are staggered, and the positions of the respective second curved segments 422 are also staggered.

[0046] In the same supporting layer, adjacent side walls 42 have a tendency to lean closer to each other as they approach the joint 43 of the adjacent supporting layers; and at the joint 43 of adjacent supporting layers, in the same supporting layer, the starting point of the first curved section 421 of the side wall 42 is connected to the end point of the first curved section 421 of the other adjacent side wall 42 that is staggered therewith, and the starting point of the second curved section 422 of the side wall 42 is connected to the end point of the second curved section 422 of the other adjacent side wall 42 that is staggered therewith, so that the support channels 41 in the adjacent supporting layers are connected.

[0047] The starting points and end points of the first curved section 421 and the second curved section 422 in the side wall 42 are inclined along the extension direction of the corresponding support channel 41, and the corresponding inclination directions of the first curved section 421 and the second curved section 422 in the same side wall 42 are the same, and the corresponding inclination directions in adjacent side walls 42 are opposite.

[0048] In the support assembly 40, the distances along the channel direction between the starting points and the end points of the first curved section 421 and the second curved section 422 of the side wall 42 of the support layer located above the partition layer 44 are smaller than the distances along the channel direction between the starting points and the end points of the first curved section 421 and the second curved section 422 of the side wall 42 of the support layer located below the partition layer 44.

[0049] The closer the side wall 42 is to the junction 43 of adjacent support layers, the greater the curvature thereof.

[0050] The upper covering layer 10 is located at the top, the lower covering layer 20 is located at the bottom, and mutually perpendicular arrangement directions and channel directions are defined in the horizontal direction. The arrangement directions and channel directions here are relative to each supporting layer, and are not absolute directions.

[0051] Specifically, refer to Figure 2 and Figure 3 , Figure 2 The structure of the support layer above the spacer 44 is shown. Figure 3 The bottom structure of the lowest support layer disposed on the interlayer 44 is shown. Since the sole rebound boosting structure provided in this embodiment is prepared by 3D printing, the overall structure is built by stacking layers from bottom to top, and this specification also describes its structure in this way. At the same time, the structure of the support layer above the interlayer 44 is similar to that of the support layer below the interlayer 44, and they differ only in size, so the structure of the support layer above the interlayer 44 is taken as an example for description.

[0052] Figure 2 The khaki part is the coating layer surrounding the support assembly 40, see Figure 1The coating layer includes an upper coating layer 10 located at the upper side, a lower coating layer 20 located at the lower side, and a side coating layer located at the peripheral side. Figure 2 , the bright yellow part is the support layer, the main body of the support layer is the side wall 42 used to form the support channel 41, and the space between the two side walls 42 is the support channel 41. Although the side wall 42 has a curved structure, the support channel 41 generally extends in a fixed direction, and its extension direction is the channel direction of the support layer. At the same time, the bottom support layer includes a plurality of support channels 41, and these support channels 41 are arranged along a fixed direction, which is the corresponding arrangement direction of the support layer. Figure 3 As an example, in this top view, there are defined left-right direction and front-back direction. Here, the front-back direction is Figure 3 The up-down direction in the view, but to distinguish it from the up-down direction mentioned above, it is defined as the front-to-back direction. At this time, the channel direction of the bottom support layer is the left-right direction, and the arrangement direction is the front-to-back direction. Figure 5 , which shows the situation of the penultimate support layer from bottom to top above the interlayer 44. It can be seen that in this support layer, the channel direction becomes the front-to-back direction, and the arrangement direction becomes the left-to-right direction. It can be seen that for adjacent support layers, the channel direction and arrangement direction are periodically changed. At the same time, adjacent support layers are interconnected, so the support layers above the interlayer 44 are interconnected, and the support layers below the interlayer 44 are also interconnected.

[0053] Reference Figure 3 , the side wall 42 is periodically arranged with the first curved section 421 and the second curved section 422 connected end to end along the left-right direction, that is, the channel direction of the support layer. Taking the side wall 42 located at the front as an example, starting from the left end, the first curved section 421, the second curved section 422, the first curved section 421, the second curved section 422... are arranged in sequence to the rightmost end, wherein the first curved section 421 starts from the left end and extends smoothly and bends forward to the right, and the second curved section 422 starts from the end point of the first curved section 421, and extends smoothly and bends backward to the right, and the starting point of the first curved section 421 and the end point of the second curved section 422 are at the same position in the front-to-back direction. Thus, the side wall 42 forms a periodic curved structure.

[0054] At the same time, refer to Figure 3, the first curved section 421 of the other side wall 42 behind the frontmost side wall 42, that is, the other side wall 42 adjacent to the frontmost side wall 42, is staggered, and the second curved section 422 is also staggered. The staggered here means that the starting position of the first curved section 421 of the frontmost side wall 42 roughly corresponds to the position of the end point of the corresponding first curved section 421 of the adjacent side wall 42 in the left-right direction. The corresponding position here is not completely opposite, but there is a certain inclination, so that the side wall 42 is inclined in the left-right direction.

[0055] Reference Figure 4 The side wall 42 of the lowest support layer above the spacer 44 is gradually stacked upwards. Figure 4 It can be seen that the starting and ending points of the first curved section 421 and the second curved section 422 in the side wall 42 of the support layer are inclined along the extension direction of the corresponding support channel 41. In the bottom support layer, the starting and ending points of the first curved section 421 and the second curved section 422 of the frontmost side wall 42 are inclined toward the left, while the starting and ending points of the first curved section 421 and the second curved section 422 of the other side wall 42 adjacent to the frontmost side wall 42 are inclined toward the right. In this way, in the same support layer, adjacent side walls 42 have a tendency to be closer to each other as they are closer to the joint 43 of the adjacent support layer.

[0056] Continue to refer to Figure 4 , the bottom support layer above the partition 44 intersects with the penultimate support layer, at which point the top of the side wall 42 of the bottom support layer begins to connect with the adjacent side wall 42, where the starting point of the first curved section 421 on the side wall 42 connects with the end point of the first curved section 421 on the other side wall 42, and the starting point of the second curved section 422 on the side wall 42 connects with the starting point of the second curved section 422 on the other side wall 42. At the location of the connecting point 43, the side wall 42 of the penultimate support layer begins to extend in the front-to-back direction. Figure 5 , upward from the junction 43, the side wall 42 of the penultimate support layer gradually extends upward, and the curvature gradually decreases. After that, the side walls 42 of the penultimate support layer will gradually approach each other until they are connected to form the junction 43.

[0057] Reference Figure 6In this embodiment, a partition 44 is provided in the support assembly 40. The partition 44 is arranged horizontally and is located between two adjacent support layers. The partition 44 is made of the same material as the upper cover 10, the lower cover 20 or the side cover 30, and is also formed in the support assembly 40 by 3D printing. The partition 44 is airtight and can isolate the upper and lower support layers, thereby separating the support assembly 40 into two independent parts, and the support layers in the two parts are connected to each other. The partition 44 is arranged in the middle position in the up-down direction of the support assembly 40, and the entire support assembly 40 can be divided into two isolated parts. Each isolated part independently compresses and releases the air inside it, and the partition 44 itself can play the role of pulling the support layer in the horizontal direction, and the support performance of the support layer will be improved, and the impact energy can be better absorbed; at the same time, the partition 44 can also provide the overall rigidity of the sole rebound boosting structure, improve the bending moment of the sole, and provide better rebound performance in the process of recovering deformation after being squeezed.

[0058] Reference Figure 7 , which shows the structure of the support layer below the spacer 44. Figure 5 and Figure 7 It can be seen that the distances along the channel direction between the first curved section 421 and the starting point and the end point of the second curved section 422 of the side wall 42 of the support layer above the interlayer 44 are greater than the distances along the channel direction between the first curved section 421 and the starting point and the end point of the second curved section 422 of the side wall 42 of the support layer below the interlayer 44. This makes the density of the support layer above the interlayer 44 smaller, and can provide a more comfortable wearing feeling, while the density of the support layer below the interlayer 44 is larger, and can provide better support performance through a denser structure. Among them, the distances along the channel direction between the starting point and the end point of the first curved section 421 and the second curved section 422 refer to the entire distance calculated from the starting point of the first curved section 421, along the channel direction of the support layer, until reaching the end point of the second curved section 422. It should be noted that since the side wall 42 has a tendency to tilt, this distance can be obtained by measuring the side wall 42 at different heights and taking the average value.

[0059] Reference Figure 1The support assembly 40 protrudes upward at the middle of its top to form a support platform 45, and a shock absorbing table 46 is formed around the support platform 45; the support platform 45 and the shock absorbing table 46 are both enclosed by the upper cover layer 10 and are both located above the partition layer 44. In addition, the bottom of the support assembly 40 is in the shape of an arc extending from front to back, and the arc protrudes downward. The support assembly 40 forms a support platform 45 and a shock absorbing surface 46. The support platform 45 protrudes from the shock absorbing surface 46, and the support platform 45 is the part that directly contacts the foot. When the protruding support platform 45 is squeezed by the foot, its shape will change, thereby transferring the force to the bottom and the side. The shock absorbing surface 46 plays the role of receiving the force transmitted by the support platform 45, so that the support platform 45 will not deform too violently, so that the support platform 45 maintains sufficient structural stability for support. Therefore, through the cooperation of the support platform 45 and the shock absorbing surface 46, the sole rebound boosting structure can provide a softer foot feel while having a better support effect. The bottom of the support assembly 40 is in the shape of a downwardly protruding arc. When applied to the forefoot part of the sole, it can better fit the shape of the forefoot and the physiological curvature of the foot, providing users with a better foot feel and shock absorbing support performance.

[0060] In the sole rebound boosting structure provided by the utility model, an upper covering layer 10, a lower covering layer 20, a side floating layer and a support component 40 are provided. The support component 40 is provided with a support layer, and the upper covering layer 10, the lower covering layer 20 and the side floating layer surround the support component 40 from top to bottom and all around, so that the support component 40 forms a sealed structure; the support layer in the support component 40 is provided with a support channel 41, and the support channel 41 can accommodate air. At the same time, the channel directions of the support channels 41 of adjacent support layers are perpendicular to each other, and the adjacent support layers are interconnected; when the upper covering layer 10 is subjected to downward pressure, the support component 40 as a whole will be squeezed, so that the air in the support channel 41 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 41 of adjacent support layers are in a staggered form, when the support component 40 is squeezed, the force received will be quickly and evenly dispersed to the entire support component. 40, thereby providing a better shock-absorbing effect through the entire support assembly 40; and, a partition 44 is arranged in the middle position in the upper and lower directions of the support assembly 40, the partition 44 divides the entire support assembly 40 into two mutually isolated parts, each isolated part independently compresses and releases the air inside it, and the partition 44 itself will play a role in pulling the support layer in the horizontal direction, the supporting performance of the support layer will be improved, and the impact energy can be better absorbed; in addition, the size of the support channel 41 below the partition 44 is smaller than the size of the support channel 41 above the partition 44, so that the support layer above the partition 44 can have a lower hardness, better fit the shape of the foot when worn, and provide a better foot feel; the partition 44 arranged in the middle not only plays an insulating role, but also can provide the overall rigidity of the sole rebound boosting structure, improve the bending moment of the sole, and provide better rebound performance in the process of recovering deformation after being squeezed; the support layer below the partition 44 has a higher hardness, which can effectively improve the supporting performance of the sole.

[0061] In addition, the utility model also provides another embodiment, which is a sole. The sole adopts the above-mentioned sole rebound boosting structure, so it has a better wearing feel and shock-absorbing support performance.

[0062] Specifically, the forefoot portion of the midsole of the sole adopts the sole rebound-boosting structure provided in the above-mentioned embodiment, and the arch portion and heel portion of the midsole of the sole may adopt other materials, or components similar to the above-mentioned sole rebound-boosting structure may be adopted throughout the entire palm. However, it should be noted that the external shape of the sole rebound-boosting structure needs to be modified and adjusted accordingly corresponding to the arch portion and the heel portion.

[0063] 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.
