Description

Technical Field

[0001] This utility model relates to the field of shoe sole technology, specifically to a shoe sole support component, a shoe sole, and a shoe. Background Technology

[0002] Shoes are footwear worn during walking, running, and competitive sports, consisting of an upper and a sole fixed to the upper. When worn, the foot is positioned between the upper and the sole, with the sole located below the upper and foot but above the ground. The sole acts as the carrier of the foot's impact on the ground and also serves as a bridge for the ground's reaction force on the foot. To enhance foot comfort, soles typically incorporate cushioning components, such as air cushions, which are bladders containing pressurized gas. Because the pressurized gas is sealed within the bladder, the bladder expands under pressure, allowing it to be compressed to absorb energy and achieve shock absorption. The internal gas pressure also enables the air cushion to withstand a certain amount of external pressure, providing support and energy return. However, air cushions are prone to rupture under excessive pressure, punctures, aging, or other causes, leading to gas leakage and loss of cushioning and support functions. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide a sole support component, sole, and shoe. The sole support component can provide stable support for the foot and also has a shock-absorbing effect, so that the sole and shoe have good sports performance and comfort.

[0023] The nineteenth technical solution relates to a shoe sole having an inner cavity, which includes a shoe sole support component as described in any of the first to sixteenth technical solutions. The shoe sole support component is adapted to the inner cavity. The inner cavity has an upper surface and a lower surface. The outer surface of the top wall of the bladder is connected to the upper surface of the shoe sole inner cavity, and the outer surface of the bottom wall of the bladder is connected to the lower surface of the shoe sole inner cavity.

[0024] The twentieth technical solution is based on the nineteenth technical solution, wherein the outer surface of the top wall of the bladder is fixedly connected to the upper surface of the inner cavity of the shoe sole, and the outer surface of the bottom wall of the bladder is fixedly connected to the lower surface of the inner cavity of the shoe sole.

[0025] The twenty-first technical solution is based on the twenty-first technical solution, wherein a groove is formed in the middle of the outer surface of the top wall of the bladder, a U-shaped groove is formed in the vertical direction on the side of the bladder, and a protrusion adapted to the U-shaped groove is provided in the inner cavity of the sole.

[0026] The twenty-second technical solution relates to a shoe, which includes a sole as described in any of the nineteenth to twenty-first technical solutions and an upper connected to the sole, wherein the sole and the upper enclose a space suitable for foot wear.

[0027] Compared with the prior art, the technical solution of this utility model and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0028] Through continuous observation, experimentation, and research, the applicant has learned that shoe soles, as a crucial medium for the foot during movement, incorporate cushioning components, such as air cushions—capsules containing pressurized gas. When placed in the sole, the air cushion provides support and cushioning due to the expandable nature of the capsule and the presence of pressurized gas. However, the applicant has discovered that a high initial pressure within the capsule can cause it to rupture under significant external pressure. Conversely, a low initial pressure results in poor support and energy return performance, making it unsuitable for sports. Furthermore, the capsule is prone to aging or puncture, leading to a complete loss of cushioning and support. Therefore, after long-term observation and identifying these shortcomings, the applicant creatively proposed adding a support component within the capsule. This approach fully utilizes the compressibility of the fluid within the capsule to maximize its cushioning function while mitigating its rupture and poor energy return properties, creating a sole support component with excellent cushioning, support, and energy return performance.

[0029] The applicant further discovered that for a shoe sole to possess support and energy return properties, it needs to distribute forces in multiple directions to obtain multi-directional reaction forces, which is beneficial for support; and to aggregate the dispersed forces into a force in a specific direction, which is beneficial for energy return and movement. Therefore, realizing the process of dispersing and then aggregating forces is key to achieving stable support and good movement performance in the support components. Thus, designing a corresponding structure to achieve the above-mentioned force transmission process is the core of solving the technical problem of ensuring stable support and good movement performance in the support components.

[0030] In the first technical solution, the support component inside the bladder acts as a bracket, enhancing the pressure-bearing capacity of the sole support assembly. Even under significant localized pressure from the foot, the bladder is less prone to rupture. The pressurized fluid inside the bladder and the support component work together to support the top and bottom walls of the bladder, distributing the pressure and thus extending the service life of the sole support assembly. Even in the event of bladder rupture and leakage of pressurized fluid, the sole support assembly still provides support and cushioning due to the support and shock absorption functions of the support component.

[0031] In the structural design of the support component, since the projections of each first support portion and each second support portion do not overlap on the projection plane perpendicular to the vertical direction, and at least three adjacent projections of second support portions are evenly distributed around the projection of a portion of the first support portion, each first support portion is connected to each adjacent second support portion through the first support arm, and at least three adjacent projections of first support portions are evenly distributed around the projection of a portion of the second support portion, each second support portion is connected to each adjacent first support portion through the first support arm. Therefore, after a portion of the second support portion bears the force transmitted from the top wall of the bladder, it transmits the force to at least three adjacent first support portions through at least three first support arms, achieving force dispersion, and at least three first support arms support the second support portion, providing stable support for the second support portion, thereby providing stable support for the foot. The evenly distributed projections of at least three adjacent second support portions around the projection of a portion of the first support portion, each first support portion connected to each adjacent first support portion through the first support arm, also achieve force aggregation, resulting in better ground reaction force and improving the athletic performance of the sole.

[0032] In the second technical solution, the projection of the connection point on the same first support arm connected to the first support part does not coincide with the projection of the connection point on the second support part. That is, the first support arm is inclined in the vertical direction, which can convert the vertical force on the second support part into a force inclined in the vertical direction. This decomposes the force inclined in the vertical direction into a horizontal force and a vertical force, thereby dispersing and canceling the force and improving the supporting function of the support member.

[0033] In the third technical solution, the line connecting the projection of the connection point on the first support arm connected to the first support part and the projection of the connection point on the second support part extends from the connection point of the first support part away from the first support part. That is, the first support arm extends obliquely outward from the first support part to the second support part. Compared with extending obliquely inward to the second support part, this is more conducive to the spatial arrangement of the first support part, the second support part and the first support arm. More first support parts, second support parts and first support arms can be arranged in the same space, which further improves the supporting effect of the support member.

[0034] In the fourth technical solution, a structure with four first support arms is adopted. When the second support is subjected to force, the force is transmitted to the four adjacent first support parts through the four first support arms, thus better distributing the force. The four first support arms also support the second support part, providing stable support and thus offering stable support for the foot. At least four adjacent projections of the second support parts are evenly distributed around the projection of a portion of the first support part. The second support part is connected to each adjacent first support part through the first support arms, further achieving force aggregation and obtaining better ground reaction force to improve energy return performance.

[0035] In the fifth technical solution, since the four first support arms connected to the same first support part are arranged orthogonally in pairs, the first support part and the second support part are symmetrical in the direction of force, so that the force is more evenly distributed, the support force is more balanced, and the support effect is more stable.

[0036] In the sixth technical solution, on a projection plane perpendicular to the vertical direction, six adjacent projections of second supports are evenly distributed around the projection of a portion of the first support. Each first support is connected to each adjacent second support via a first support arm. Three adjacent projections of the first support are evenly distributed around the projection of a portion of the second support, and each second support is connected to each adjacent first support via a first support arm. Therefore, compared to the support component of the first technical solution, the first support occupies more space, has better overall integrity, and provides better support for the second supports. Conversely, the second supports are more fragmented, which is more conducive to force distribution and provides better stability.

[0037] In the seventh technical solution, the third support is located above the fourth support and below the second support. On the projection plane perpendicular to the vertical direction, the projections of each third support and each fourth support do not overlap. Around the projections of some third supports are four adjacent projections of the second supports, and each third support is connected to its adjacent second support via the second support arm. Similarly, around the projections of some fourth supports are four adjacent projections of the second supports, and each fourth support is connected to its adjacent second support via the third support arm. Around the projections of some second supports are two projections of the third support and two projections of the fourth support, and each second support is connected to its adjacent third support via the second support arm and to its adjacent fourth support via the third support arm. In this structural arrangement, the second, third, and fourth supports are staggered vertically, adding a support platform. This fully utilizes space to set up the support structure, increasing the structural density per unit space, further enhancing the force dispersion effect and overall support function. While providing stable support, the increased support structure also brings more elastic deformation, strengthening the shock absorption effect of the support components.

[0038] In the eighth technical solution, since the third support part is connected to the fourth support part adjacent to each projection through the fourth support arm, the support arm is further added to better realize the force distribution and transmission and elastic deformation, thereby improving the support and shock absorption functions of the support component.

[0039] In the ninth technical solution, two second support arms connected to the same second support part are arranged facing each other, and two third support arms are arranged facing each other. The second support arms and third support arms of the second support part are arranged orthogonally, so that the second support part is symmetrical in the direction of force, so that the force is more evenly distributed, the support force is more balanced, and the support member can achieve a more stable support function.

[0040] In the tenth technical solution, the projections of the second support part, the third support part, and the fourth support part are arranged at equal intervals, which is conducive to the spatial arrangement of the support components and the balanced force of each support part.

[0041] In the eleventh technical solution, the fourth support arm is inclined in the vertical direction, which can convert the vertical force on the fourth support part into a force inclined in the vertical direction, thereby partially decomposing the force inclined in the vertical direction into a force in the horizontal direction, realizing the dispersion and cancellation of force, and improving the supporting function of the support member.

[0042] In the twelfth technical solution, the line connecting the projection of the connection point of the fourth support arm to the third support part and the projection of the connection point of the fourth support part extends from the connection point of the third support part away from the third support part. That is, the fourth support arm extends obliquely outward from the third support part to the fourth support part. Compared with extending obliquely inward to the fourth support part, this is more conducive to the spatial arrangement of the third support part, the fourth support part and the fourth support arm, and improves the supporting effect of the support member.

[0043] In the thirteenth technical solution, the third and fourth support arms are arranged at intervals on the fourth support part, which is conducive to spatial arrangement and force balance, and improves the stability of the support component.

[0044] In the fourteenth technical solution, the projections of the four second support arms and the 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 conducive to the balanced force on the third support part and the spatial arrangement of the second support arms and the third support arms.

[0045] In the fifteenth technical solution, the second support arm is connected to the upper end face of the third support part, and the fourth support arm is connected to the lower end face of the third support part, thereby enhancing the force-bearing capacity and force balance of the third support part.

[0046] In the sixteenth technical solution, the shape of the second support arm is designed to create clearance space while being inclined in the vertical direction. Because the second support arm connects the uppermost second support part and the lowermost fourth support part, and only the middle section is inclined, it facilitates the demolding manufacturing of the support member of this application in the form of mold closing.

[0047] In the seventeenth technical solution, the first support is fixedly connected to the inner surface of the bottom wall of the bladder, and the second support is fixedly connected to the inner surface of the top wall of the bladder. On the one hand, the fixed connection of the supports to the top and bottom walls of the bladder helps to restrain the bladder, limiting its expansion and deformation, increasing the bladder's ability to withstand internal fluid pressure, and making it less prone to rupture. On the other hand, there are portions on the top and bottom walls of the bladder that are not fixedly connected to the supports, namely the gaps between the second supports and the gaps between the first supports. These portions are not held in place by the supports and expand under the pressure inside the bladder, slightly protruding from the fixedly connected portions. When force is applied to the bladder by the foot, these portions deform first, thus providing better cushioning for the foot. Furthermore, after the expanded portions are compressed, the pressurized fluid inside the bladder and the supports work together to provide support, cushioning, and energy return to the sole. The fixed connection method facilitates processing and shaping, resulting in a more stable connection.

[0048] The technical effect of the eighteenth technical solution is the same as that of the seventeenth technical solution.

[0049] In the nineteenth technical solution, the sole with the above-mentioned sole support component has the functions and effects described above. The sole support component is in contact with the inner cavity of the sole, which facilitates installation.

[0050] In the twentieth technical solution, the sole support component is fixedly connected to the inner cavity of the sole, which can better position and restrain the bladder, avoid wear on the outer wall of the bladder, and extend the service life of the sole support component.

[0051] In the twenty-first technical solution, a groove is formed in the middle of the outer surface of the top wall of the bladder, which is conducive to the fixed connection between the top wall of the bladder and the inner cavity of the shoe sole by applying adhesive. The connection is firm and no glue overflow occurs. A U-shaped groove is formed on the side of the bladder in the vertical direction. A protrusion adapted to the U-shaped groove is provided in the inner cavity of the shoe sole, which is convenient for positioning and installing the shoe sole support component.

[0052] In the twenty-second technical solution, a shoe with a sole containing the sole support components described above has good support, movement and comfort. Attached Figure Description

[0081] Shoes consist of a sole and an upper, among other components. The sole is the core component providing support, cushioning, and energy return for the foot, adapting to various scenarios such as walking, running, and competitive sports. To enable certain functions in the sole, functional components are incorporated to fulfill functional requirements. The sole support component of this application serves as a part of the sole, supporting it. The sole has an inner cavity, which can be located along the entire sole or at the heel, depending on the stress requirements. In the embodiments of this application, the inner cavity is located at the heel, and its size can be adjusted as needed. The sole support component is fitted into this inner cavity. The inner cavity has an upper surface and a lower surface, which can also be non-planar depending on the foot structure or stress requirements. In this application, both the upper and lower surfaces of the inner cavity are curved surfaces.

[0082] Example 1

[0083] The sole support assembly 10 of this embodiment includes a bladder 11 and a support member 1. The bladder 11 is made of an elastic material and has a top wall 12, a bottom wall 13, and side walls, which together enclose a closed cavity containing a pressurized fluid and the support member 1. The pressurized fluid can be a gas such as nitrogen, or a fluid; in this embodiment, a gas is used. After the bladder 11 is sealed to contain the pressurized fluid, it is adapted to expand under the pressure of the pressurized fluid. The bottom wall 13 and the top wall 12 of the bladder are respectively adapted to connect to the lower and upper surfaces of the inner cavity of the sole to support the sole.

[0084] Support component 1, see Figure 1 , Figure 1A schematic diagram of the support member 1 in this embodiment is shown, specifically a projection diagram of the support member 1 on a projection plane perpendicular to the vertical direction. The support member 1 is disposed inside the bladder 11 and includes several first support portions 2, several second support portions 3, and several first support arms 4. In the vertical direction, the first support portions 2 are located below the second support portions 3. The first support portions 2 and the second support portions 3 are respectively connected to the inner surfaces of the bottom wall 13 and the top wall 12 of the bladder. Each first support portion 2 has a corresponding lower end surface adapted to abut against the inner surface of the bottom wall 13 of the bladder, and each second support portion 3 has a corresponding upper end surface adapted to abut against the inner surface of the top wall 12 of the bladder to support the sole of the shoe. On the projection plane perpendicular to the vertical direction, the projections of each first support part 2 and each second support part 3 do not overlap. The projections of each first support part 2 and each second support part 3 are arranged at regular intervals. Specifically, three adjacent projections of second support parts 3 are evenly distributed around the projections of some first support parts 2, that is, three adjacent projections of second support parts 3 are evenly distributed around the projections of non-edge first support parts 2; and three adjacent projections of first support parts 2 are evenly distributed around the projections of some second support parts 3, that is, three adjacent projections of first support parts 2 are evenly distributed around the projections of non-edge second support parts 3. Each second support part 3 is connected to each adjacent first support part 2 through a first support arm 4, and each first support part 2 is connected to each adjacent second support part 3 through a first support arm 4. In this embodiment, each first support part 2 is connected to its adjacent second support part 3 through only one first support arm 4. Thus, three first support arms 4 are connected to the non-edge first support part 2, and three first support arms 4 are also connected to the non-edge second support part 3. The same first support arm 4 is connected to the edges of the first support part 2 and the second support part 3 that are adjacent to each other in the projection. On the projection plane perpendicular to the vertical direction, the projection of the connection point of the same first support arm 4 connected to the first support part 2 does not coincide with the projection of the connection point connected to the second support part 3, and the line connecting the projections of the connection points extends from the connection point of the first support part 2 in a direction away from the first support part 2.

[0085] Example 2

[0086] The sole support assembly 10 of this embodiment includes a bladder 11 and a support member 1. The bladder 11 is made of an elastic material and has a top wall 12, a bottom wall 13, and side walls, which together enclose a closed cavity containing a pressurized fluid and the support member 1.

[0092] The sole support assembly 10 of this embodiment includes a bladder 11 and a support member 1. The bladder 11 is made of an elastic material and has a top wall 12, a bottom wall 13, and side walls, which together enclose a closed cavity containing a pressurized fluid and the support member 1. The pressurized fluid can be a gas such as nitrogen, or a fluid; in this embodiment, a gas is used. After the bladder 11 is sealed to contain the pressurized fluid, it is adapted to expand under the pressure of the pressurized fluid. The bottom wall 13 and the top wall 12 of the bladder are respectively adapted to connect to the lower and upper surfaces of the inner cavity of the sole to support the sole.

[0093] Support component 1, see Figures 4 to 20 , Figures 4 to 12 Views 14 to 20 show specific structural views of the sole support assembly 10 and the support member 1 in this embodiment. Figure 13A schematic diagram of the support member 1 in this embodiment is shown, specifically a projection diagram of the support member 1 on a projection plane perpendicular to the vertical direction. The support member 1 is disposed within the bladder 11 and includes several first support portions 2 and several second support portions 3. Each first support portion 2 includes a third support portion 5 and a fourth support portion 6. In the vertical direction, the third support portion 5 and the fourth support portion 6 are located below the second support portion 3, and the third support portion 5 is located above the fourth support portion 6, approximately between the second support portion 3 and the fourth support portion 6. On the projection plane perpendicular to the vertical direction, the projections of each second support portion 3, each third support portion 5, and each fourth support portion 6 do not overlap, and are arranged at equal intervals. Specifically, around the projection of a portion of the second support portion 3, two adjacent projections of the third support portion 5 and two adjacent projections of the fourth support portion 6 are evenly distributed. That is, around the projection of the non-edge second support portion 3, two adjacent projections of the third support portion 5 and two adjacent projections of the fourth support portion 6 are evenly distributed. The projections of the two adjacent third support portions 5 and two adjacent fourth support portions 6 are arranged opposite to each other around the projection of the second support portion 3, and are arranged orthogonally as a whole. Around the projection of a portion of the third support portion 5, four adjacent projections of the second support portion 3 and four adjacent projections of the fourth support portion 6 are evenly distributed. That is, around the projection of the non-edge third support portion 5... The projections of four adjacent second support portions 3 and four adjacent fourth support portions 6 are evenly distributed, and the projections of the four second support portions 3 and four adjacent fourth support portions 6 are spaced apart around the projection of the third support portion 5; the projections of four adjacent second support portions 3 and four adjacent third support portions 5 are evenly distributed around the projection of a portion of the fourth support portion 6, that is, the projections of four adjacent second support portions 3 and four adjacent third support portions 5 are evenly distributed around the projection of the non-edge fourth support portion 6, and the projections of the four second support portions 3 and four adjacent third support portions 5 are spaced apart around the projection of the fourth support portion 6. The second support portion 3 is a type of square platform with an upper end face, and the upper end faces of several second support portions 3 together form a surface suitable for connecting with the inner surface of the top wall 12 of the capsule to abut against the top wall 12 of the supporting capsule. The third support portion 5 is a circular platform with an upper end face and a lower end face. The fourth support part 6 is also a type of square platform with a lower end face. The lower end faces of several fourth support parts 6 together form a surface suitable for connecting with the inner surface of the bottom wall 13 of the bladder body to abut against the bottom wall 13 of the bladder body.The support member 1 also includes a first support arm 4 and a fourth support arm 9. The first support arm 4 includes a second support arm 7 and a third support arm 8. Each second support part 3 is connected to each adjacent third support part 5 via the second support arm 7 and to each adjacent fourth support part 6 via the third support arm 8. Each second support part 3 is connected to each adjacent third support part 5 via a second support arm 7, and each adjacent fourth support part 6 is connected to each third support part 6 via a third support arm 8. Thus, two second support arms 7 and two third support arms 8 are connected to the non-edge second support part 3. The projections of the two second support arms 7 and two third support arms 8 connected to the same second support part 3 on the projection plane perpendicular to the vertical direction are arranged facing each other around the projection of the second support part 3, and the two are orthogonally arranged. The projections of the connection points of the same second support arm 7 with the second support part 3 and the third support part 5 on the projection plane perpendicular to the vertical direction do not coincide. The line connecting the projections of the two connection points extends from the second support part 3 along the third support part 5 in a direction away from the second support part 3, that is, the second support arm 7 is inclined in the vertical 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 part 3, the lower section extends vertically upward from the connection point with the fourth support part 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 vertical direction is greater than 0 degrees and less than 90 degrees. In this embodiment, it is preferably 45 degrees. Each third support part 5 is connected to each second support part 3 adjacent to its projection through the second support arm 7, and is connected to each fourth support part 6 adjacent to its projection through the fourth support arm 9. Each third support part 5 is connected to each second support part 3 adjacent to its projection through a second support arm 7, and each fourth support part 6 adjacent to its projection through a fourth support arm 9. Thus, four second support arms 7 and four fourth support arms 9 are connected to the non-edge third support portion. 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 distributed around the projection of the third support portion 5. The second support arms 7 are connected to the upper end face of the third support portion, and the fourth support arms 9 are connected to the lower end face of the third support portion. The projections of the connection points of the same fourth support arm 9 with the third support portion 5 and the fourth support portion 6 on the projection plane perpendicular to the vertical direction do not coincide. The line connecting the projections of the two connection points extends from the third support portion 5 to the fourth support portion 6 in a direction away from the third support portion 5, that is, the second support arm 7 is inclined in the vertical direction. Each fourth support portion 6 is connected to each second support portion 3 adjacent to its projection via a third support arm 8, and to each third support portion 5 adjacent to its projection via a fourth support arm 9. Each fourth support portion 6 is connected to each second support portion 3 adjacent to its projection via a third support arm 8, and each third support portion 5 adjacent to its projection via a fourth support arm 9.Thus, four third support arms 8 and four fourth support arms 9 are connected to the non-edge fourth support portion 6, and the projections of the four third support arms 8 and the four fourth support arms 9 connected to the same fourth support portion 6 are arranged at intervals around the projection of the fourth support portion 6.

[0094] The sole support assembly 10 of this application first forms a bladder 11 and a support member 1, then places the support member 1 inside the bladder 11. The upper end face of the second support part 3 is connected to the inner surface of the top wall 12 of the bladder, and the lower end face of the fourth support part 6 is connected to the inner surface of the bottom wall 13 of the bladder. In this embodiment, the connection method is a fixed connection, using an adhesive method to fix the upper end face of the second support part 3 to the inner surface of the top wall 12 of the bladder, and the lower end face of the fourth support part 6 to the inner surface of the bottom wall 13 of the bladder. In other embodiments, the connection method can be a non-fixed connection, as long as the support member 1 is properly limited within the bladder 11 to prevent overturning, and the gap between the upper end face of the second support part 3 and the inner surface of the top wall 12 of the bladder is not too large, the support member 1 can play the role of supporting the bladder 11 and thus supporting the sole. The fixed connection method can also be adhesive, hot melt, welding, etc. After the support member 1 is installed inside the bladder 11, nitrogen gas is injected into the bladder 11 to reach the set pressure before the bladder 11 is sealed. The bladder 11 can also be sealed by methods such as bonding, heat fusion, or welding. Since the upper end face of the second support part 3 is fixedly connected to the inner surface of the top wall 12 of the bladder, and the lower end face of the fourth support part 6 is fixedly connected to the inner surface of the bottom wall 13 of the bladder, the support member 1 is fixedly connected to the top wall 12 and the bottom wall 13 of the bladder. When the bladder 11 expands under air pressure, the support member 1 restricts the expansion of the bladder 11 in the vertical direction. This is equivalent to the support member 1 holding the top wall 12 and the bottom wall 13 of the bladder 11. On the one hand, this improves the pressure-bearing capacity of the bladder 11, allowing higher air pressure to be injected into the bladder 11, thus improving the support and energy return performance of the inflatable bladder 11 for the sole. On the other hand, it strengthens the bladder 11 and extends its service life.

[0095] After the sole support component 10 is formed, it is installed in the inner cavity of the sole. The top wall 12 of the bladder is connected to the upper surface of the inner cavity of the sole, and the bottom wall 13 of the bladder is connected to the lower surface of the inner cavity of the sole. In this embodiment, the connection is fixed by adhesive. A groove is formed in the middle of the outer surface of the top wall 12 of the bladder, which facilitates bonding with the inner cavity of the sole by applying adhesive, resulting in a stronger connection and preventing adhesive overflow. A U-shaped groove is formed on the side of the bladder 11, which facilitates the matching and positioning of the protrusions in the inner cavity of the sole, making positioning and installation convenient. After the sole support component 10 is assembled into the inner cavity of the sole, when the foot applies force to the sole during wear, the upper surface of the inner cavity of the sole transmits the force to the bladder 11. Since the upper end face of the second support portion 3 in this embodiment is fixedly connected to the inner surface of the top wall 12 of the bladder, and there are gaps between the second support portions 3, meaning that the top wall 12 of the bladder has a portion not fixedly connected to the support member 1, this portion is not held by the support member 1 and expands under the pressure of the air inside the bladder 11, protruding slightly upwards from the portion fixedly connected to the second support portion 3. Similarly, the portion of the bottom wall 13 of the bladder not fixedly connected to the fourth support portion 6 protrudes slightly downwards from the portion fixedly connected to the fourth support portion 6. During the force application process, the above two portions are compressed and deformed first, providing cushioning for the sole. When the compression deformation reaches a certain amount, the portion of the bladder 11 fixedly connected to the second support portion 3 begins to bear force. From this point onwards, the sealed gas inside the bladder 11 and the support member 1 jointly bear the force transmitted from the sole. Therefore, compared to the technical solution where no support member 1 is provided inside the bladder 11, firstly, the pressure-bearing capacity of the bladder 11 is improved, and the service life of the inflatable bladder 11 is increased; secondly, even when the bladder 11 ruptures and cannot exert its air pressure function, the sole support component 10 of this application can still provide support, cushioning, and energy return performance for the sole. Thirdly, compared to air cushions, which have poor support stability due to their good gas flow, the sole support component 10 of this application provides better support and energy return performance under the action of the support member 1. Specifically, during the process of the support member 1 being subjected to force, after the second support part 3 is subjected to force, the second support part 3 transmits the force to the third support part 5 through the second support arm 7, and transmits the force to the fourth support part 6 through the third support arm 8. Since the second support arm 7 and the third support arm 8, which are connected to the same second support part 3, are arranged orthogonally 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 preventing twisting; on the other hand, the force on the upper surface of the second support part 3 will be evenly distributed, and since the second support arm 7 and the third support arm 8 are inclined rigid connecting rods, the vertical force on the second support part 3 will be partially converted into horizontal force, effectively reducing 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, further converting 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, which are connected to the same third support part 5, are evenly spaced, and the horizontal forces acting on the same third support part 5 can be partially canceled out. The third support arm 8 and the fourth support arm 9, which are connected to the same fourth support part 6, are also evenly spaced, and the horizontal forces are further partially canceled out, further reducing the horizontal force. This reduces the force transmitted from the fourth support part 6 to the bottom wall 13 of the shoe body, thereby reducing the force of the ground reaction on the sole of the shoe, effectively reducing the force of the ground reaction on the foot, and improving foot comfort. Furthermore, the same third support part 5, which is not on the edge, is connected to multiple second support arms 7 and fourth support arms 9 arranged at intervals, and the same fourth support part 6, which is not on the edge, is connected to multiple third support arms 8 and fourth support arms 9 arranged at even intervals, which can provide stable support for the third support part 5 and the fourth support part 6, thereby providing stable support for the bladder 11 and even the sole.

Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
