Background

With the development of social economy, the material level of people is continuously improved, more and more people attach importance to health, and more people participate in sports and body building in daily life. In the running process, due to the action of inertia, when the bottom of the shoes of a sporter touches the ground, the soles can receive the downward pressure exerted on the soles by the gravity of the human body and the reverse impact force (generally 3 to 5 times of the weight of the human body) exerted on the soles by the bottom surface, and the impact force easily causes certain damage to human body structures such as knee joints and/or ankle joints of the sporter. Therefore, shoes are footwear for protecting the legs and feet from injury, and the shock absorbing function of the shoes is very important and necessary.

Many shoes with cushioning function in the prior market are improved on the material or structure of the sole, for example, on the sole material, foamed thermoplastic polyurethane material with good cushioning effect is adopted, and on the sole structure, the structures such as an air cushion, a cushioning column and the like are designed. However, for improvement of sole materials, the cushioning properties required by different positions of the sole are different, and the sole made of the same material cannot meet the requirement; with respect to the improvement of the sole structure, there is a problem in that the overall structure is hard and low in comfort.

The embodiment of the invention provides a sole buffering support structure, which can be applied to soles and used as midsoles of the soles. The present embodiment is described mainly with respect to a sole cushioning support structure.

Referring to fig. 1 and 2, there is shown the outline of the sole cushioning support structure provided by the present embodiment, on top of which is provided a support platform 21 and a cushioning table 22. Referring also to fig. 3, the sole buffering support structure provided in this embodiment includes a support assembly 10 and an outer wall 30, fig. 3 shows an internal configuration of the sole buffering support structure after removing a portion of the outer wall 30, wherein the support assembly 10 is a bright yellow portion in fig. 3, the outer wall 30 is a earthy yellow portion in fig. 3, and the outer wall 30 covers the outer circumference of the closed support assembly 10.

In this embodiment, the sole cushioning support structure is prepared by adopting a 3D printing mode, the adopted material may be a thermoplastic polyurethane elastomer, and the thermoplastic polyurethane elastomer material may be selected from commercial products, such as a commercially available AU-brand polyurethane material, a kesi-AU-brand polyurethane material, a road-blob-brand polyurethane material, and the like. Or nylon can be adopted as the material, and the material mark can be selected according to actual needs. It should be appreciated that in this embodiment, when the sole cushioning support structure is made of different materials, there will necessarily be a difference in cushioning properties, but this difference will not affect the function of the sole cushioning support structure. The materials used for the support assembly 10 and the outer wall 30 may be the same or different, and the materials used for different portions inside the support assembly 10 may be the same or different. It should be noted that the outer wall 30 should be made of a material having air tightness, and may cooperate with the support assembly 10 to form a closed air chamber when the outer wall 30 covers the outer circumference of the closed support assembly 10.

Referring to fig. 4 to 7, the supporting assembly 10 is provided with a plurality of supporting layers 11 along an up-down direction, each supporting layer 11 defines an arrangement direction and a channel direction which are perpendicular to each other, each supporting layer 11 is provided with a plurality of supporting channels 12 which are sequentially arranged along the arrangement direction, and each supporting channel 12 positioned on the same supporting layer 11 extends along the channel direction; adjacent supporting layers 11 are mutually communicated, the respective corresponding arrangement directions are mutually perpendicular, and the channel directions are mutually perpendicular; the middle position of the top of the supporting component 10 is provided with a convex supporting platform 21 formed by the supporting layer 11, and a cushioning table-board 22 lower than the supporting platform 21 is formed on the periphery of the supporting platform 21; an outer wall 30 covers the outer periphery of the support assembly 10 to enclose the support assembly 10 to form a closed air chamber.

Preferably, the supporting platform 21 and the cushioning table-board 22 are smoothly transited by adjusting the height of the corresponding supporting layer 11.

In addition, in each support layer 11 of the support assembly 10, the support channels 12 are formed by the cooperation of two opposite side walls 13 arranged along the corresponding arrangement direction of the support layer 11; the side wall 13 is periodically provided with a first bending section 14 and a second bending section 15 which are connected end to end along the channel direction corresponding to the supporting layer 11 where the side wall is positioned, and the bending directions of the first bending section 14 and the second bending section 15 are opposite; between two adjacent side walls 13 in the same supporting layer 11, the positions of the first bending sections 14 are staggered, and the positions of the second bending sections 15 are also staggered.

In the same support layer 11, adjacent side walls 13 have a tendency to incline closer to each other as they approach the junctions 16 of adjacent support layers 11; and in the same supporting layer 11, at the junction 16 of the adjacent supporting layers 11, the beginning of the first bending section 14 of the side wall 13 is connected with the end of the first bending section 14 staggered with the first bending section of the adjacent other side wall 13, and the beginning of the second bending section 15 of the side wall 13 is connected with the end of the second bending section 15 staggered with the second bending section of the adjacent other side wall 13, so that the supporting channels 12 in the adjacent supporting layers 11 are communicated.

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

The closer the side wall 13 is to the junction 16 of the adjacent support layers 11, the greater the degree of bending.

The structure of the support assembly 10 will be first described in detail.

Because the sole buffering support structure provided in this embodiment is printed by stacking layers in a 3D printing manner, the structure is built up by gradually stacking layers from bottom to top, and therefore the structure of the support assembly 10 is also described by adopting a corresponding layer-by-layer paving manner. Fig. 4 to 7 are illustrations of various stages of laying down sequentially from the bottom up in a laying stacking order.

Referring to fig. 3, the support assembly 10 is composed of several support layers 11 arranged one above the other; referring to fig. 4, the body of the support layer 11 is a sidewall 13 for forming the support channel 12, and a space between the two sidewalls 13 is the support channel 12. Referring to fig. 4, the supporting layer 11 shown in fig. 4 is taken as the supporting layer 11 of the first layer, and although the side wall 13 has a curved structure, the supporting channel 12 still extends in a substantially fixed direction, and the extending direction is the channel direction of the supporting layer 11; meanwhile, the supporting layer 11 of the first layer includes a plurality of supporting channels 12, and the supporting channels 12 are arranged along a fixed direction, that is, an arrangement direction corresponding to the supporting layer 11. Taking the paper surface direction of fig. 4 as an example, the channel direction of the support layer 11 of the first layer is the left-right direction, and the arrangement direction is the up-down direction. Further, referring to fig. 7, there is shown a structure of a support layer 11 of a second layer adjacent above the support layer 11 of the first layer, in which the channel direction becomes the up-down direction and the arrangement direction becomes the left-right direction in the support layer 11 of the second layer. It can be seen that the channel direction and the arrangement direction of the adjacent support layers 11 are periodically changed. Meanwhile, the adjacent supporting layers 11 are mutually communicated, when the outer wall 30 seals the whole supporting assembly 10, the first air cushion part integrally forms a sealed first air chamber, and the supporting layers 11 are arranged inside the first air chamber.

Referring to fig. 4 and 5, taking the paper surface direction of fig. 4 and 5 as an example, in the first supporting layer 11, the side walls 13 are periodically arranged with the first curved sections 14 and the second curved sections 15 connected end to end in the left-right direction, that is, the channel direction of the supporting layer 11. Taking one side wall 13 as an example, the side wall is sequentially arranged from the left end to the rightmost end in the form of a first bending section 14, a second bending section 15, a first bending section 14 and a second bending section 15 … …, wherein the first bending section 14 is obliquely and smoothly bent and extended forwards from the left end to the right, the second bending section 15 is obliquely and smoothly bent and extended backwards from the end point of the first bending section 14, and the initial point of the first bending section 14 and the end point of the second bending section 15 are positioned at the same position in the front-back direction. Thereby, the side wall 13 forms a periodically curved structure.

Meanwhile, with continued reference to fig. 4 and 5, taking the above-exemplified side wall 13 as an example, the other side wall 13 below or above and adjacent to the side wall 13 is offset in the position of the first curved section 14 thereof and also offset in the position of the second curved section 15 thereof. By offset is meant herein that the extent of the side wall 13 defined by the beginning and end of the first curved section 14 or the second curved section 15 of one side wall 13 is not within the extent of the beginning or end of the first curved section 14 or the second curved section 15 of the other side wall 13 adjacent thereto. That is, the curved sections on adjacent side walls 13 are not exactly opposite.

Referring to fig. 5 and 6, the side walls 13 of the support layer 11 of the first layer are gradually laid up to be shaped. As can be seen in fig. 5, the start and end points of the first and second curved sections 14, 15 in the side walls 13 of the support layer 11 are inclined in the extending direction of the corresponding support channel 12, and the start and end points of the first and second curved sections 14, 15 of one side wall 13 are inclined to the left and the start and end points of the first and second curved sections 14, 15 of the other side wall 13 adjacent to the side wall 13 are inclined to the right in the support layer 11 of the first layer. In this way, adjacent side walls 13 have a tendency to tilt closer to each other in the same support layer 11 as closer to the junction 16 of adjacent support layers 11. Referring back to fig. 6, the first support layer 11 and the second support layer 11 intersect, where the uppermost side wall 13 of the first support layer 11 begins to meet the adjacent side wall 13, where the beginning of the first curved section 14 on the side wall 13 meets the end of the first curved section 14 on the other side wall 13, and the beginning of the second curved section 15 on the side wall 13 meets the beginning of the second curved section 15 on the other side wall 13. Taking the paper surface direction of fig. 6 as an example, at the position of the contact 16, the side wall 13 of the support layer 11 of the second layer starts to take on a form extending in the up-down direction. Referring to fig. 7, the sidewall 13 of the support layer 11 of the second layer is gradually extended upward, and the degree of bending is gradually reduced, and a main portion of the sidewall 13 takes a form extending in the up-down direction. Thereafter, the side walls 13 of the support layer 11 of the second layer are gradually inclined toward each other until they are connected to each other to form a junction 16.

The structure of the support assembly 10 described above enables the outer wall 30 to form a closed air chamber inside the support assembly 10 after closing the support assembly 10; the support assembly 10 is provided with a plurality of support layers 11, the support layers 11 are provided with support channels 12, the support channels 12 can accommodate air, meanwhile, the channel directions of the support channels 12 of adjacent support layers 11 are mutually perpendicular, the adjacent support layers 11 are mutually communicated, and a closed first air chamber is formed by sealing the outer walls 30; when the first air cushion portion is pressed downward, the first air cushion portion is pressed as a whole, so that air in the supporting channel 12 is compressed, after the pressure is removed, the original volume of the air can be restored, in the process, the air is pressed and restored to have a certain cushioning effect, meanwhile, adjacent supporting layers 11 can be mutually supported, and because the supporting channels 12 of the adjacent supporting layers 11 are in a mutually staggered form, when the first air cushion portion is pressed, the received force can be rapidly and uniformly dispersed into the whole first air cushion portion, so that a better cushioning effect is provided through the whole first air cushion portion, and better rebound performance can also be provided.

Referring to fig. 1 and 2, a support platform 21 is formed at a middle position by setting a laying position of the support layer 11 on top of the support assembly 10, and in this embodiment, the number of support platforms 21 is one and matches with the outer contour of the support assembly 10, and a cushioning table 22 is formed at a portion between the support platform 21 and the outer contour of the support assembly 10. It should be understood that the supporting platform 21 is formed by the supporting layers 11, and because each supporting layer 11 of the supporting component 10 is laid layer by 3D printing, when the supporting layer 11 is laid at the top position of the supporting component 10, the supporting layer 11 can be continuously laid only at the middle part where the supporting platform 21 needs to be formed, and the part of the cushioning table 22 stops laying, thereby forming the supporting platform 21 and the cushioning table 22. Meanwhile, referring to fig. 1 and 2, at the transition portion between the support platform 21 and the cushioning mesa 22, the height of the support layer 11 is adjusted by adjusting the height of the support layer 11, which means the height of the support layer 11 between the support platform 21 and the cushioning mesa 22, so that the top surface of the support platform 21 can be smoothly transitioned to the cushioning mesa 22 by gradually decreasing from the support platform 21 toward the cushioning mesa 22.

Forming a supporting platform 21 and a cushioning table 22 by the supporting component 10, wherein the supporting platform 21 protrudes from the cushioning table 22, and the supporting platform 21 is a part directly contacted with the foot; through the protruding supporting platform 21, when the supporting platform is extruded by feet, the shape of the supporting platform is changed, so that the stress is transferred to the bottom and the sides, and the cushioning table top 22 plays a role in receiving the force transferred by the supporting platform 21, so that the supporting platform 21 cannot be deformed too severely, and the supporting platform 21 can maintain enough structural stability for supporting; therefore, through the cooperation of supporting platform 21 and buffering mesa 22, this sole buffering bearing structure can have better supporting effect when providing softer foot sense.

In addition, the invention also provides another embodiment, namely the sole, which adopts the sole buffering support structure, so that the sole has better foot feeling and buffering support performance when being worn.

Specifically, the sole cushioning support structure provided by the above embodiments is used in the half sole of the sole, and other materials may be used in the arch portion and heel portion of the sole, or similar components to those described above in the sole cushioning support structure may be used throughout the sole. Wherein the bottom of the support assembly 10 has an arc shape extending from front to rear, and the arc is downwardly protruded. Through the arc-shaped bottom protruding downwards, when the sole buffering support structure is applied to the middle sole half sole part of the sole, the shape and the physiological bending radian of the sole half sole pad can be more attached. At the same time, it should be noted that the external shape of the sole cushioning support structure, corresponding to the arch region and the heel region, requires corresponding modification and adjustment.

The foregoing description of the embodiments and description is presented to illustrate the scope of the invention, but is not to be construed as limiting the scope of the invention. Modifications, equivalents, and other improvements to the embodiments of the invention or portions of the features disclosed herein, as may occur to persons skilled in the art upon use of the invention or the teachings of the embodiments, are intended to be included within the scope of the invention, as may be desired by persons skilled in the art from a logical analysis, reasoning, or limited testing, in combination with the common general knowledge and/or knowledge of the prior art.
