[0021] The seventeenth technical solution relates to a sole, which is provided with an inner cavity, including any one of the sole support members in the first to sixteenth technical solutions, wherein the sole support member is adapted in the inner cavity, and the inner cavity is provided with an upper surface and a lower surface, the first supporting portion is connected to the lower surface of the inner cavity of the sole, and the second supporting portion is connected to the upper surface of the inner cavity of the sole.

[0022] The eighteenth technical solution is based on the seventeenth technical solution, wherein the first supporting portion is fixedly connected to the lower surface of the inner cavity of the sole, and the second supporting portion is fixedly connected to the upper surface of the inner cavity of the sole.

[0023] The nineteenth technical solution relates to a shoe, which comprises the sole described in the seventeenth technical solution or the eighteenth technical solution and an upper connected to the sole, wherein the sole and the upper enclose a space suitable for the foot to wear.

[0024] Compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0025] The applicant has learned through continuous observation, experimentation and research that the sole is an important medium for the foot during movement. The sole disperses the force applied by the foot to multiple directions to obtain reaction force, which is beneficial for the foot to obtain balance and provide stable and reliable support for the foot. Aggregating the dispersed force into a force in a specific direction is beneficial for the foot to move and achieve good movement results. Therefore, the process of the sole dispersing and then aggregating the force is the key to achieving the sole's stable support function and maintaining good movement characteristics. Therefore, designing a corresponding structure to enable the sole to achieve the above force transmission process is the core of solving the technical problem of the sole having a stable support function and good movement performance.

[0026] In the first technical solution, on the projection plane perpendicular to the up-down direction, the projection of each first support part does not overlap with the projection of each second support part, and the projection of at least three adjacent second support parts are evenly distributed around the projection of part of the first support part, and the first support part is connected to each adjacent second support part through the first support arm, and the projection of at least three adjacent first support parts are evenly distributed around the projection of part of the second support part, and the second support part is connected to each adjacent first support part through the first support arm. Therefore, the structure is set up so that after the part of the second support part receives the force transmitted from the upper surface of the inner cavity of the sole, it is transmitted to at least three adjacent first support parts through at least three first support arms, so that the force is dispersed, and at least three first support arms support the second support part, which plays a role of stabilizing support for the second support part, thereby providing stable support for the foot. The projection of at least three adjacent second support parts is evenly distributed around the projection of part of the first support part, and the first support part is connected to each adjacent first support part through the first support arm, and the aggregation of force is achieved to obtain a better ground reaction force, so as to improve the sports performance of the sole.

[0027] In the second technical solution, on the projection plane perpendicular to the up-down direction, the projection of the connection point on the same first support arm connected to the first support part and the projection of the connection point connected to the second support part do not overlap, that is, the first support arm is arranged obliquely in the up-down direction, so that the up-down force received by the second support part can be converted into a force inclined in the up-down direction, thereby decomposing the force inclined in the up-down direction into horizontal force and up-down force, realizing force dispersion and force offset, and enhancing the supporting effect.

[0028] In the third technical solution, a line connecting the projection of a connection point on the same first support arm connected to the first support portion and a line connecting the projection of a connection point on the same first support arm connected to the second support portion extends from the connection point of the first support portion toward a direction away from the first support portion, that is, the first support arm extends obliquely outward from the first support portion to the second support portion, which is beneficial to the spatial arrangement of the first support portion, the second support portion and the first support arm compared to extending obliquely inward to the second support portion, and more first support portions, second support portions and first support arms are arranged in the same space, thereby further improving the supporting effect.

[0029] In the fourth technical solution, the structure of four first support arms is adopted, so that after the part of the second support part receives the force transmitted from the upper surface of the inner cavity of the sole, it is transmitted to the four adjacent first support parts through the four first support arms, so as to better achieve the dispersion of force, and the four first support arms support the second support part, which plays a role of stabilizing the second support part, thereby providing stable support for the foot. The projection of the part of the first support part is evenly distributed around the projection of at least four adjacent second support parts, and the second support part is connected to each adjacent first support part through the first support arm, which better achieves the aggregation of force, so as to obtain a better ground reaction force, so as to improve the sports performance of the sole.

[0030] In the fifth technical solution, since the four first support arms connected to the same first support part are arranged orthogonally relative to each other, the first support part and the second support part are symmetrical in the direction of the force they are subjected to, so that the force is more evenly dispersed, the supporting force is more balanced, and a more stable supporting effect is achieved.

[0031] In the sixth technical solution, on the projection plane perpendicular to the up-down direction, the projection of part of the first support part is evenly distributed around the projection of six adjacent second support parts, and the first support part is respectively connected to each adjacent second support part through the first support arm, and the projection of part of the second support part is evenly distributed around the projection of three adjacent first support parts, and the second support part is connected to each projection of the adjacent first support part through the first support arm. Therefore, compared with the first technical solution, the first support part occupies a larger space, has better integrity, and has a better supporting effect on the second support part. Relatively speaking, the second support part is more fragmented, which is more conducive to the dispersion of force and has better stability.

[0032] In the seventh technical solution, the third support portion is located above the fourth support portion and below the second support portion; on the projection plane perpendicular to the up and down directions, the projections of each third support portion do not overlap with the projections of each fourth support portion, and the projections of four adjacent second support portions are evenly distributed around the projections of part of the third support portion, and the third support portion is respectively connected to the second support portion adjacent to each projection through the second support arm, and the projections of four adjacent second support portions are evenly distributed around the projections of part of the fourth support portion, and the fourth support portion is respectively connected to the second support portion adjacent to each projection through the third support arm, and the projections of two third support portions and two fourth support portions are evenly distributed around the projections of part of the second support portion, and the second support portion is connected to the third support portion adjacent to each projection through the second support arm and to the fourth support portion adjacent to each projection through the third support arm. In this structural setting, the second support part, the third support part, and the fourth support part are staggered in the up and down directions. Compared with the first technical solution, one more layer of support platform is set up to make full use of the space to set up the support structure, improve the structural density in the unit space, and further enhance the force dispersion effect and the overall support effect. While providing stable support, more support structures also bring more elastic deformations, and the shock-absorbing effect of the support structure is also strengthened.

[0033] In the eighth technical solution, since the third support portion is connected to the fourth support portion adjacent to each projection through the fourth support arm, further support arms are provided to better achieve force dispersion transmission and elastic deformation, thereby enhancing the supporting and shock-absorbing effects.

[0034] In the ninth technical solution, the two second support arms connected to the same second support part are arranged facing each other, and the two third support arms are arranged facing each other, and the second support arm and the third support arm of the second support part are arranged orthogonally, so that the second support part is symmetrical in the force direction, achieving more uniform force dispersion, more balanced supporting force, and a more stable supporting effect.

[0035] In the tenth technical solution, the projections of the second supporting part, the third supporting part, and the fourth supporting part are arranged at equal intervals, which is beneficial to the spatial layout and the balanced force of each supporting part.

[0036] In the eleventh technical solution, the fourth support arm is arranged to be inclined in the up and down directions, so that the up and down force received by the fourth support part can be converted into a force inclined in the up and down directions, thereby partially decomposing the force inclined in the up and down directions into a horizontal force, thereby achieving force dispersion and force offset, and enhancing the supporting effect.

[0037] In the twelfth technical solution, a line connecting the projection of a connection point of the same fourth support arm connected to the third support portion and the projection of a connection point connected to the fourth support portion extends from the connection point of the third support portion toward away from the third support portion, that is, the fourth support arm extends obliquely outward from the third support portion to the fourth support portion, which is beneficial to the spatial arrangement of the third support portion, the fourth support portion and the fourth support arm, compared to extending obliquely inward to the fourth support portion, and enhances the overall supporting effect.

[0038] In the thirteenth technical solution, the third support arm and the fourth support arm are arranged at intervals on the fourth support portion, which is beneficial to spatial arrangement and force balance.

[0039] In the fourteenth technical solution, the projections of four second support arms and four third support arms connected to the same third support part are arranged at intervals around the projection of the third support part, which is beneficial to the balanced force of the third support part and the spatial arrangement of the second support arms and the third support arms.

[0040] In the fifteenth technical solution, the second support arm is connected to the upper end surface of the third connection part, and the fourth support arm is connected to the lower end surface of the third connection part, which facilitates the spatial structure setting and enhances the force-bearing capacity and force balance of the third support part.

[0041] In the sixteenth technical solution, the shape of the second support arm is conducive to forming an avoidance space while being inclined in the up-down direction. Because the second support arm connects the second support portion at the top and the fourth support portion at the bottom, only the middle section is inclined, which facilitates the demoulding manufacturing of the sole support member of the present application in a mold-matching form.

[0042] In the seventeenth technical solution, the sole provided with the sole support has the functions and effects as described above, and the first support part is in contact with the inner cavity of the sole, which is convenient for installation.

[0043] In the eighteenth technical solution, a fixed connection method is adopted, which is easy to process and solidify, and the connection is more stable.

[0044] In the nineteenth technical solution, the shoes using the sole structure as described above have the functions and effects of good support, mobility and comfort. BRIEF DESCRIPTION OF THE DRAWINGS

The projections of the two second support arms 7 and the two third support arms 8 connected to the same second support portion 3 on the projection plane perpendicular to the up-down direction are arranged opposite to each other around the projection of the second support portion 3, and the two are arranged orthogonally. The projections of the connection points of the same second support arm 7, the second support portion 3 and the third support portion 5 on the projection plane perpendicular to the up-down direction do not overlap, and the connecting line of the projections of the two connection points extends from the second support portion 3 to the third support portion 5 in the direction away from the second support portion 3, that is, the second support arm 7 is arranged obliquely in the up-down direction. The same third support arm 8 is divided into an upper section, a middle section and a lower section. The upper section extends vertically downward from the connection point with the second support portion 3, the lower section extends vertically upward from the connection point with the fourth support portion 6, and the middle section connects the upper section and the lower section. The angle between its extension direction and the projection plane perpendicular to the up-down direction is greater than 0 degrees and less than 90 degrees, and is preferably 45 degrees in this embodiment. Each third support portion 5 is connected to each second support portion 3 adjacent to each projection through a second support arm 7, and is connected to each fourth support portion 6 adjacent to each projection through a fourth support arm 9. Each third support portion 5 is connected to each second support portion 3 adjacent to its projection through a second support arm 7, and is connected to each fourth support portion 6 adjacent to its projection through a fourth support arm 9. In this way, four second support arms 7 and four fourth support arms 9 are connected to the non-edge third connection portion, and the projections of the four second support arms 7 and the four fourth support arms 9 connected to the same third support portion 5 are evenly spaced around the projection of the third support portion 5, and the second support arm 7 is connected to the upper end surface of the third connection portion, and the fourth support arm 9 is connected to the lower end surface of the third connection portion.

Each fourth support portion 6 is connected to each second support portion 3 adjacent to its projection through a third support arm 8, and is connected to each third support portion 5 adjacent to its projection through a fourth support arm 9. Each fourth support portion 6 is connected to each second support portion 3 adjacent to its projection through a third support arm 8, and is connected to each third support portion 5 adjacent to its projection through a fourth support arm 9.

[0074] After the sole support 1 is installed in the inner cavity of the sole, the upper end surface of the second support part 3 is connected to the upper surface of the inner cavity of the sole, and the lower end surface of the fourth support part 6 is connected to the lower surface of the inner cavity of the sole, and the connection can be an adhesive fixed connection. When the foot applies force to the sole, the upper surface of the inner cavity of the sole transfers the force to the upper end surface of the second support part 3. After the second support part 3 is subjected to force, the force is transferred to the third support part 5 through the second support arm 7, and the force is transferred to the fourth support part 6 through the third support arm 8. Since the second support arm 7 and the third support arm 8 connected to the same second support part 3 are arranged orthogonally relative to the second support part 3, on the one hand, the second support arm 7 and the third support arm 8 stably support the second support part 3, thereby providing stable support for the foot and avoiding twisting; on the other hand, the force on the upper end surface of the second support part 3 will be evenly dispersed, and since the second support arm 7 and the third support arm 8 are inclined rigid connecting rods, the vertical force received by the second support part 3 will be partially converted into horizontal force, effectively weakening the transmission of vertical force. Similarly, after the third support part 5 is subjected to force, the force is transmitted to the fourth support part 6 through the fourth support arm 9. The fourth support arm 9 is also an inclined rigid connecting rod, which further converts the force into horizontal and vertical forces acting on the fourth support part 6. The second support arm 7 and the fourth support arm 9 connected to the same third support part 5 are arranged at intervals, and the horizontal force acting on the same third support part 5 can be partially offset. The third support arm 8 and the fourth support arm 9 connected to the same fourth support part 6 are also arranged at intervals, and the horizontal force is further partially offset, further reducing the horizontal force, so that the force transmitted to the inner cavity of the sole by the fourth support part 6 is reduced, and the force of the ground reacting on the sole is reduced, which effectively reduces the force of the ground reacting on the foot and improves the comfort of the foot. In addition, the same non-edge third support portion 5 is connected to a plurality of evenly spaced second support arms 7 and fourth support arms 9, and the same non-edge fourth support portion 6 is connected to a plurality of evenly spaced third support arms 8 and fourth support arms 9, which can provide stable support for the third support portion 5 and the fourth support portion 6, thereby providing stable support for the sole.
