Description

Technical Field

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

[0002] With socio-economic development and the continuous improvement of people's living standards, more and more people are paying attention to health and participating more in sports and fitness in their daily lives. During activities such as running, due to inertia, the sole of the shoe experiences downward pressure from the body's weight and a counter-impact force from the ground (generally equivalent to 3 to 5 times the body weight) at the moment of impact. This impact can easily cause damage to the knee and / or ankle joints. Therefore, shoes are footwear designed to protect the legs and feet from injury, and the cushioning function of shoes is extremely important and necessary.

[0003] Many shoes on the market with cushioning features improve the material or structure of the sole. For example, in terms of sole material, they use foamed thermoplastic polyurethane material with good cushioning effect, and in terms of sole structure, they design air cushions, shock-absorbing columns, and other structures. However, regarding improvements to sole materials, different parts of the sole require different cushioning performance, and soles made of the same material cannot meet these needs. As for improvements to sole structure, there are problems such as an overall stiff structure and low comfort. Utility Model Content

[0030] In addition, this utility model also provides technical solution 26: a shoe, which includes an upper and a sole based on any one of technical solutions 23 to 25, wherein the upper is attached to the sole.

[0031] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects: Ideal shock absorbers need to dissipate energy under small impacts and provide structural stiffness to ensure support under larger impacts. The mechanical response of conventional homogeneous materials or simple structures is usually linear or monotonic, and it is difficult to optimize flexibility and support for different magnitudes of impact in a uniform structure. For example, structures that rely mainly on the elastic deformation of materials usually have high initial stiffness to obtain end support, thus reducing comfort under low impacts.

[0032] Technical Solution 1 provides a cushioning support component. Through structural shape improvements, this component forms a structure similar to origami. When the component is subjected to initial pressure along a second direction, the opening edges of the first groove open from the top wall towards the bottom wall, and the opening edges of the second groove open from the bottom wall towards the top wall. This opposing opening configuration allows the grooves to contract and fold inward along a third direction upon initial pressure. Specifically, when the top and bottom walls approach each other, the first and second support sections rotate relative to each other around the connecting wall, reducing the width of the openings of the first and second grooves, and causing the groove walls to tilt inward and converge. During this process, energy is mainly dissipated through the rotation of the support sections around the connecting wall and the bending deformation of the groove walls. Because the bending deformation of the groove walls and the rotation of the support sections require less resistance in the initial stage, the component exhibits low stiffness in the early stages of pressure, enabling it to complete the initial cushioning stroke with less force under large displacement, thereby transforming instantaneous impact into a gradual cushioning process and improving comfort during initial contact. As compression increases, the openings of the first and second grooves continuously narrow, the rotation angle of the support section gradually increases, and the distance between the groove walls continuously decreases. When the openings narrow to a certain extent, or the inner surfaces of the groove walls begin to contact each other, or the rotation of the support section is geometrically constrained and approaches its limit, the force required for further compression increases non-linearly. At this point, the mechanical mode of the component shifts from primarily structural folding to primarily structural compaction and material compression, resulting in increased stiffness and entering a high-support mechanical stage. This stage can resist larger impact forces, preventing the component from failing due to excessive compression, thus ensuring the support safety during movement.

[0033] Conventional hollow columnar structures are prone to overall instability or disordered lateral buckling under compression, leading to unpredictable damping performance. The opposing opening configuration of the two grooves in this application provides a clear deformation path under compression: the first and second support segments rotate symmetrically inward about the connecting wall as the centerline, while the first and second grooves contract synchronously, causing the entire support module to converge inward along a third direction. This ensures the stability and controllability of the deformation process, preventing torsional or shear failure. The connecting wall, as the shared boundary of the first and second support segments, acts as a geometric constraint and force transmission pivot during deformation, ensuring coordinated movement of the support segments on both sides and further enhancing the structure's resistance to instability.

[0034] Furthermore, the first and second grooves are recessed along a third direction, and the first and second sidewalls extend along a first direction, giving the component differentiated stiffness characteristics in the three orthogonal directions: the first, second, and third directions. When the component is subjected to non-perpendicular impacts, such as complex loads with longitudinal or lateral components, the sidewalls extending along the first direction provide longitudinal shear resistance, and the groove structure recessed along the third direction provides lateral buffering capacity, enabling the component to maintain a stable mechanical response under multi-directional loads.

[0035] Since the mechanical properties of a component primarily stem from the geometry of the support module rather than material properties, this allows for functional customization. By parametrically adjusting the geometry of the support module at different locations—such as the depth of the groove, the opening angle of the slot, and the thickness of the connecting wall—the initial stiffness, folding stroke, and support stiffness during the compaction stage can be controlled at that location. This enables differentiated combinations of damping and support performance in different areas of the same component, based on biomechanical requirements, achieving zoned functional design that is difficult to achieve with traditional homogeneous materials or simple structures.

[0036] In technical solution two, the circumferential dimensions of the first and second grooves gradually increase from the bottom to the top, giving the grooves a funnel-shaped or trumpet-shaped expansion configuration. When the component is under pressure, because the groove opening width is greater than the groove bottom width, the support section has more room to move during rotation, and the groove walls do not contact each other prematurely, resulting in a longer stroke during the structural folding stage and a gentler initial damping effect. Simultaneously, the gradual increase in circumferential dimensions causes differences in the inclination angle of the groove walls at different heights. This geometric gradient guides the support section to fold layer by layer along a preset path under pressure, avoiding sudden force jumps caused by local buckling and improving the stability and controllability of the damping process.

[0037] In technical solution three, the support channel wall extends obliquely from the bottom to the top of the channel relative to a third direction. Under pressure, the obliquely extended support channel wall can undergo controllable bending deformation along its oblique direction. This bending direction is consistent with the direction of channel opening contraction, allowing the rotation of the support section and the bending of the channel wall to form a coordinated deformation mode, resulting in higher energy dissipation efficiency. Simultaneously, the oblique angle results in a longer effective length of the channel wall in the initial stage of compression, requiring less force for bending deformation, further reducing initial stiffness. As the compression increases, the oblique angle of the channel wall gradually decreases, the effective length shortens, and the bending stiffness increases accordingly, allowing the component to remain flexible in the initial damping stage and provide sufficient stiffness in the support stage.

[0038] In technical solution four, the two supporting groove walls extend obliquely from opposite ends along the first direction towards the top of the groove, so that the first groove and the second groove are open in the first direction. When the component is subjected to an oblique impact with a component force in the first direction, the grooves that are open along the first direction can absorb the impact component in that direction by adjusting the distance between the groove walls, thus avoiding stress concentration caused by the oblique force being completely transmitted to the sidewalls.

[0039] In technical solution five, the connecting groove wall extends obliquely from the bottom to the top of the groove relative to a third direction. This allows the connecting wall to not only serve as the interface of the support section but also participate in the opening configuration of the groove. The oblique extension of the connecting groove wall allows it to undergo a certain degree of bending deformation under pressure, providing additional deformation freedom for the contraction of the first and second grooves. This design avoids the connecting wall being too rigid and restricting the groove opening contraction, making the folding process of the groove smoother. At the same time, the oblique direction of the connecting groove wall matches the oblique direction of the support groove wall, making the overall shape of the first and second grooves more coordinated, and the opening angle of the groove opening more uniform in the circumferential direction. This ensures that the groove can contract symmetrically and uniformly under pressure, avoiding uneven deformation caused by local preferential folding.

[0040] In technical solution six, the two connecting groove walls of the connecting wall extend inclinedly from opposite ends along the second direction from the bottom of the groove towards the top of the groove, so that the first groove and the second groove also open towards each other at the connecting wall. When the component is under pressure, the connecting groove walls on both sides of the connecting wall can tilt inward symmetrically, guiding the first support section and the second support section to rotate symmetrically about the connecting wall as the center line, so that the contraction process of the two grooves is synchronized, avoiding the situation where one side of the groove closes first while the other side lags behind.

[0041] In technical solution seven, the groove wall extends obliquely from the bottom to the top of the groove in a third direction, allowing the top and bottom walls within the first and second grooves to participate in the opening configuration. This all-around oblique extension design makes the groove shape more regular, and the opening angle of the groove opening remains consistent throughout the circumference, ensuring that the folding behavior of the groove under pressure has high symmetry and predictability. Simultaneously, the obliqueness of the groove wall causes the effective thickness of the top and bottom walls at the groove location to vary along a third direction. This thickness gradient can regulate the local stiffness of the top and bottom walls at that location, matching it with the rotational stiffness of the support section, thus preventing excessive stiffness of the top or bottom wall from hindering the rotation of the support section.

[0042] In technical solution eight, the groove walls of the top and bottom walls extend obliquely from opposite ends along the second direction towards the top of the groove, causing the first groove at the top wall position and the second groove at the bottom wall position to also exhibit an open shape along the second direction. This design allows the grooves to not only open in the third direction but also have an expanding configuration in the second direction. When the component is under pressure, this three-dimensional opening configuration can provide deformation space in both the second and third directions simultaneously, allowing the folding of the grooves to be not limited to contraction in a single direction but to undergo complex deformation with multiple degrees of freedom. This enables the component to adapt to more complex load conditions and maintain stable shock absorption performance under non-uniform pressure distribution or multi-directional impact.

[0043] In technical solution nine, the junction of the supporting groove wall and the connecting groove wall features a bend, forming a clear geometric ridge between the two groove walls. This bend acts as a hinge point for preferential deformation under pressure, guiding the groove wall to bend controllably at that location. The bend transition concentrates deformation at the ridge, creating a clear folding path and making the groove's contraction process more orderly. When the component is under pressure, the supporting groove wall and the connecting groove wall bend first at the bend, causing the entire groove to contract according to a preset folding pattern, preventing unexpected buckling of the groove wall at other locations and improving the controllability and repeatability of deformation.

[0044] In technical solution ten, the first groove has a top wall groove recessed at its top wall position, and the second groove has a bottom wall groove recessed at its bottom wall position. This allows the grooves to recess not only into the body but also towards the outer surface of the body. This design increases the total depth of the grooves, providing more space for the groove opening to contract. When the component is under pressure, the top and bottom wall grooves can accommodate the portion that protrudes outward after the support section rotates, preventing interference between the support section and the top or bottom wall when rotating at large angles. This allows the grooves to achieve a larger amount of contraction, extending the stroke of the initial damping stage. At the same time, the presence of the top and bottom wall grooves reduces the stiffness of the top and bottom walls at that location, making them more prone to local bending deformation to match the contraction of the grooves, resulting in more coordinated deformation of the entire support module.

[0045] In technical solution eleven, the second groove has a through-hole along the second direction at its bottom wall position, creating an open configuration at the bottom wall. Conventional components typically avoid through-hole openings in the bottom wall to ensure its integrity and strength, as these openings may weaken the load-bearing capacity. This solution, by creating a through-hole along the second direction at the bottom wall position of the second groove, completely opens the bottom of the second groove. When the component is under pressure, the second support section rotates inward around the connecting wall. If the bottom wall is a closed structure, the rotation of the second support section is restricted by the inner surface of the bottom wall, limiting the rotation angle. The through-hole design eliminates this restriction, allowing the second support section to rotate freely towards the bottom wall without obstruction from the inner surface, resulting in a longer contraction stroke of the second groove, greater displacement in the initial damping phase, and a more effective damping effect. Furthermore, the through-hole reduces the amount of material used in the bottom wall at this location. Given that the second groove already has sufficient support capacity, reducing the weight of the bottom wall reduces the overall weight of the component, meeting the requirements of lightweight design.

[0046] In technical solution twelve, the first and second grooves penetrate the body along a third direction at the bottom of the grooves, forming a through hole that runs through the entire thickness of the component. The presence of the through hole eliminates the constraint of the groove bottom, allowing the first and second support sections to rotate without obstruction from the groove bottom, enabling rotation at a larger angle and further extending the initial cushioning stroke. In addition, the through hole reduces material usage, lowers the overall weight of the component, and reduces the burden on the sole while ensuring cushioning support performance.

[0047] In technical solution thirteen, the portions of the first and second support sections used to form the groove edge are constructed as conical ridges, a first convex ridge, and a second convex ridge. The sharp geometric shape of the conical ridges provides a clear positioning line for the groove edge, guiding the support sections to rotate along this positioning line under pressure, ensuring the accuracy of the folding path. Simultaneously, the presence of the conical ridges increases the local stiffness of the groove edge, making it less prone to deformation in the initial stages of pressure. Instead, the deformation is transferred to the support sections and the groove wall, allowing energy dissipation primarily to be achieved through the rotation of the support sections and the bending of the groove wall, thus preventing structural failure caused by premature deformation of the groove edge.

[0048] In technical solution fourteen, the portion of the connecting wall used to form the edges of the first and second grooves is configured as a conical ridge-shaped third ridge, which is shared by both grooves. Under pressure, this third ridge coordinates the folding behavior of the two grooves, ensuring that the first and second support sections rotate symmetrically around the ridge line, thus keeping the contraction of the two grooves synchronized. Simultaneously, the conical ridge shape gives the connecting wall high bending stiffness at this location, enabling it to maintain shape stability under pressure and providing a reliable pivot for the rotation of the support sections, preventing deviation of the folding path due to torsional deformation of the connecting wall.

[0049] In technical solution fifteen, the portion of the connecting wall used to form the edge of the slot is configured as a platform-ridge-shaped third ridge, which is shared by both slots. The flatness of the platform ridge enhances the compressive strength of the connecting wall at this location, enabling it to withstand greater vertical pressure without localized crushing. This ensures that the connecting wall maintains its geometry under large impact loads, provides a stable pivot for the support section, and guarantees the support performance of the component under high load conditions.

[0050] In technical solution sixteen, the first and second side walls, top and bottom walls of each of two adjacent support modules cooperate to form a third groove recessed along the third direction. When the component is under pressure, the third groove can deform in conjunction with the first and second grooves, further dissipating energy through the contraction of its groove opening. Simultaneously, the presence of the third groove ensures that adjacent support modules are not rigidly connected, but rather linked by a deformable groove structure. This flexible connection allows each support module to deform relatively independently, avoiding excessive constraint on the deformation of one support module by adjacent modules. This allows the entire component to achieve more uniform compression along the first direction when under pressure, improving the consistency of its shock absorption performance.

[0051] In technical solution seventeen, the first and second sidewalls constituting the third groove are connected along the first direction, dividing the third groove into a fourth and fifth groove along the second direction. This separation design allows the third groove to form two independent sub-grooves in the second direction, each capable of independent contraction and folding. When the component is under pressure, the fourth and fifth grooves can deform differently according to the difference in pressure distribution. For example, if the pressure on the top wall is greater, the fourth groove will contract first; if the pressure on the bottom wall is greater, the fifth groove will contract first. This zoned response capability allows the component to adapt to non-uniform pressure distribution and maintain a stable damping effect even under localized stress. Simultaneously, the connection point between the first and second sidewalls can act as a support point under pressure, limiting excessive compression of the third groove in the second direction and ensuring that the third groove continues to provide support during the compaction stage.

[0052] In technical solution eighteen, the circumferential dimension of the third groove gradually increases from the bottom to the top, giving it the same expansion configuration as the first and second grooves. This consistency ensures that the mechanical behavior of the third groove under pressure is coordinated with that of the first and second grooves. All three can begin folding under similar pressure levels and enter the compaction stage under similar compression, resulting in a smoother mechanical response curve for the entire component and avoiding abrupt force jumps caused by sudden changes in different grooves at different stages. Simultaneously, the gradual increase in circumferential dimension allows the third groove to also achieve progressive folding, extending the initial damping stroke and improving the damping effect.

[0053] In technical solution nineteen, the sidewall of the third groove, formed by the first and second sidewalls, extends obliquely from the bottom to the top of the groove relative to a third direction, making the third groove open from the bottom to the opening. This open configuration allows the third groove to contract inward along a third direction under pressure, dissipating energy through the oblique bending of the sidewall and the relative proximity of adjacent support modules. The obliquely extended sidewall has low bending stiffness in the initial stage of pressure, allowing the third groove to begin contracting under relatively small forces. This, combined with the folding of the first and second grooves, provides gentle initial shock absorption. As the compression increases, the oblique angle of the sidewall decreases, the bending stiffness increases, and the contraction resistance of the third groove increases accordingly, improving the stiffness of the component at this stage. This, in conjunction with the compaction stage of the first and second grooves, provides support performance.

[0054] In technical solution 20, the third groove extends through the body in a third direction at the bottom of the groove, giving it a through hole, just like the first and second grooves. This through-hole design allows the third groove to contract unimpeded under pressure, and the sidewalls can tilt freely inward without being restricted by the bottom of the groove, achieving a greater amount of contraction.

[0055] In technical solution twenty-one, the line connecting the bottoms of the first and second grooves is inclined relative to the second direction, so that the bottoms of the two grooves are not on the same horizontal plane, but are arranged at an angle. This inclined design gives the support module a tendency to deform under pressure, guiding the component to fold preferentially in a specific direction. When the component is applied to the sole, by adjusting the inclination direction of the groove bottom connection, the component can have differentiated cushioning characteristics in the front-to-back or inside-out directions. For example, if the groove bottom connection is inclined from front to back, the component has a longer cushioning stroke at the heel and higher support stiffness at the forefoot, which can match the biomechanical characteristics of heel-first strike and forefoot-last push-off during exercise, improving the adaptability of cushioning performance to sports needs.

[0056] In technical solution twenty-two, the main body has a first side and a second side facing away from each other along a third direction, and support modules are provided opposite to each other on the two sides along the third direction. This design enables the component to have a cushioning structure on both sides of the third direction, providing symmetrical support for both sides. When the component is applied to the inner or outer side of the sole, the support modules on the first and second sides can respectively cope with lateral forces from the inner and outer sides, preventing the sole from rolling inward or outward. At the same time, the support modules arranged opposite to each other on the two sides can deform symmetrically under pressure, keeping the mechanical response of the component in the third direction balanced, avoiding the overall structural tilt caused by excessive deformation on one side, and improving the stability and predictability of the cushioning process.

[0057] Technical solution twenty-three provides a shoe sole that employs the aforementioned cushioning support component. The cushioning support component itself possesses non-linear, progressive shock absorption and support performance. When applied to the shoe sole, it can dissipate the impact force experienced by the wearer during exercise, reducing damage to the knee and ankle joints. Simultaneously, the cushioning support component can be arranged according to the needs of different areas of the shoe sole. For example, it can be used in the heel or arch areas where pressure is high to specifically enhance the cushioning performance in these areas. Other areas can use a conventional structure, achieving a zoned functional design of the shoe sole. This ensures the performance of key components while controlling the overall weight and cost of the shoe sole. Furthermore, the structural design of the cushioning support component makes it durable, extending its service life and preventing conventional shoe soles from rapidly losing their cushioning performance due to prolonged pressure.

[0058] In technical solution 24, the length direction of the sole is the first direction of the cushioning support component, and the thickness direction is the second direction. The dimension of the support module in the second direction increases and then decreases from the front to the rear of the sole. The forefoot requires high flexibility to adapt to flexion movements during exercise; a smaller second-direction dimension results in a thinner overall thickness and lower stiffness of the cushioning support component at this location, making it easier to bend. The arch and heel bear greater impact forces and require stronger support; a larger second-direction dimension allows the cushioning support component at these locations to have a longer folding stroke and higher compaction stiffness, providing more adequate cushioning and more solid support. This gradient dimension design along the length direction enables differentiated mechanical properties in different parts of the sole, meeting the different biomechanical needs of the forefoot, arch, and heel.

[0059] In technical solution twenty-five, the line connecting the bottoms of the first and second grooves in the support module, relative to the second direction, initially slopes backward from bottom to top from the front to the rear of the sole, transitions to being parallel to the second direction, and then transitions to slope forward from bottom to top. This change in slope direction gives the support module different deformation tendencies at different positions on the sole. At the heel, the backward slope of the groove bottom line causes the support module to tend to fold backward under pressure, conforming to the forward rolling tendency of the foot when the heel strikes, guiding the impact force to be transmitted and dissipated along the rolling direction of the foot, and improving the comfort of heel cushioning. At the arch, the parallelity of the groove bottom line to the second direction causes the support module to fold vertically under pressure, providing stable vertical support and maintaining the shape of the arch. At the forefoot, the forward slope of the groove bottom line causes the support module to tend to fold forward under pressure, coordinating with the forward propulsion action of the foot when the forefoot pushes off the ground, making the cushioning deformation consistent with the direction of movement, improving the rolling sensation and propulsion efficiency during movement.

[0060] Technical solution 26 provides a shoe comprising an upper and a sole as described in any of the preceding claims, the upper being attached to the sole. The sole provides cushioning and support, and after the upper is attached, the cushioning effect of the sole is transmitted to the foot. Simultaneously, the upper wraps around the foot, working in conjunction with the sole to fix the foot's position, preventing the foot from sliding inside the shoe during exercise and improving wearing stability.

[0069] Example 1 Embodiment 1 of this utility model relates to a shoe, which includes as follows: Figure 5 , Figure 6 The shoe sole 300 is shown, as well as the upper attached to the shoe sole 300. (See reference.) Figure 1 and Figure 5 The sole 300 at least partially employs a shock-absorbing support component according to an embodiment of the present invention. In this embodiment, the midsole of the sole 300 is composed of the shock-absorbing support component.

[0070] The structure of the shock-absorbing support component involved in this embodiment will be described first below.

[0071] Reference Figure 1 The shock-absorbing support component includes a body 100, which extends along a first direction and has opposing top walls 111 and bottom walls 112 along a second direction. At least one support module 200 is arranged between the top walls 111 and bottom walls 112 along the first direction. The first direction is perpendicular to the second direction. The support module 200 includes a first side wall 211, a second side wall 212, and a connecting wall 213. The first side walls 211 and 212 are arranged along the first direction, and their two ends in the second direction are respectively connected to the top wall 111 and the bottom wall 112. The connecting wall 213 connects the first side wall 211 and the second side wall 212 along the first direction. The first side wall 211 and the second side wall 212 are separated by the connecting wall 213 along a third direction. Each has a first support section 221 and a second support section 222. The top wall 111, the two first support sections 221 and the connecting wall 213 enclose a first groove 231 recessed along a third direction. The bottom wall 112, the two second support sections 222 and the connecting wall 213 enclose a second groove 232 recessed along a third direction. The first groove 231 and the second groove 232 are arranged along a third direction. The third direction is perpendicular to the first direction and the second direction. The groove edge formed by the two first support sections 221 in the first groove 231 opens from the top wall 111 toward the bottom wall 112. The groove edge formed by the two second support sections 222 in the second groove 232 opens from the bottom wall 112 toward the top wall 111.

[0072] Specifically, the shock-absorbing support component includes a body 100, which may be block-shaped and extend along a first direction, which may be the length direction of the body 100. A top wall 111 and a bottom wall 112 are provided on the body 100 along a second direction, where the second direction may be the thickness direction of the body 100. The top wall 111 and bottom wall 112 are located on the sides of the body 100 in the width direction, which is the third direction in this invention. The sides of the body 100 in the width direction can be defined as a first side and a second side. The top wall 111 and bottom wall 112 may be configured as slightly protruding ridge structures on the sides of the body 100, forming a slightly recessed groove structure between the top wall 111 and bottom wall 112. The support module 200 is disposed within this groove structure. Of course, the body 100 as a whole may be made of the same material, such as thermoplastic polyurethane or ethylene-vinyl acetate copolymer.

[0073] Multiple support modules 200 are arranged along the first direction on the main body 100. The number and size of the support modules 200 can be flexibly adjusted according to actual application requirements. For example, when applied to the sole 300, the density, height (i.e., the size along the second direction), groove depth, and groove opening angle of the support modules 200 at each location can be differentiated according to the force characteristics, cushioning requirements, and support requirements of different areas of the foot. In the heel area, due to the greater impact force upon landing, a larger number and larger size of support modules 200 can be set to provide a longer cushioning stroke and higher end-foot support stiffness. In the forefoot area, to balance flexibility and propulsion during push-off, the number of support modules 200 or their height along the second direction can be appropriately reduced, making the structure more flexible and deformable. In addition, the spacing between adjacent support modules 200 can also be adjusted to control the compression uniformity and local deformation independence of the overall structure.

[0074] Reference Figure 1The support module 200 itself includes a first side wall 211, a second side wall 212, and a connecting wall 213. The first side wall 211 and the second side wall 212 are spaced apart along a first direction of the body 100, and their ends in a second direction are connected to the top wall 111 and the bottom wall 112 of the body 100, respectively, thus forming a vertical support frame that extends through the thickness direction. The connecting wall 213 extends along the first direction and connects the first side wall 211 and the second side wall 212. Its position is approximately in the middle of the support module 200 in a third direction, dividing the first side wall 211 and the second side wall 212 into upper and lower parts respectively: the part above the connecting wall 213 forms a first support segment 221, used to enclose the first groove 231; the part below the connecting wall 213 forms a second support segment 222, used to enclose the second groove 232. Thus, the first side wall 211, the second side wall 212 and the connecting wall 213 together form a frame structure with a symmetrical layout. This structure not only provides boundary support for the first groove 231 and the second groove 232, but also acts as a deformation coordination unit during the compression process, guiding the two side support sections to rotate synchronously inward with the connecting wall 213 as the pivot, so as to achieve controllable narrowing of the groove opening and energy dissipation.

[0075] Reference Figure 1The shapes of the first groove 231 and the second groove 232 can be considered as symmetrical about the connecting wall 213. Specifically, the first groove 231 is formed by the top wall 111, the two first support sections 221, and the connecting wall 213, and its entire shape is recessed into the body 100 along a third direction, with the groove opening facing the first or second side of the body 100; the second groove 232 is formed by the bottom wall 112, the two second support sections 222, and the same connecting wall 213, and it is also recessed along a third direction, with the groove opening facing the opposite direction to the first groove 231. The two grooves are vertically opposed to each other in the third direction, sharing the connecting wall 213 as their respective inner boundaries. The opening of the first groove 231 is formed by the inner edges of two first support sections 221, which start from the top wall 111 and gradually open outwards towards the bottom wall 112, forming a funnel-shaped or flared entrance. Correspondingly, the opening of the second groove 232 is formed by the inner edges of two second support sections 222, which also open outwards from the bottom wall 112 towards the top wall 111. This opposing opening configuration allows the first support sections 221 and 222 to rotate inwards synchronously around the connecting wall 213 when compressed along the second direction, causing the opening widths of the first groove 231 and the second groove 232 to gradually decrease, thereby achieving controllable folding and energy dissipation of the structure. In addition, the bottoms of the first groove 231 and the second groove 232 are located near the middle of the connecting wall 213, and the bottoms of the two grooves are basically aligned in the third direction or inclined to a certain extent according to design requirements. The overall trough wall is composed of the inner side of the support section, the side of the connecting wall 213, and a portion of the top wall 111 or the bottom wall 112.

[0076] Reference Figure 1The circumferential dimensions of the first groove 231 and the second groove 232 gradually increase from the bottom to the top. Specifically, this dimensional change is reflected in the fact that the opening width of the groove at the top is significantly greater than the width at the bottom, causing the entire groove to exhibit an outwardly expanding funnel-shaped or flared configuration along the third direction. This expansion trend exists not only on the two side walls formed by the first support section 221 and the second support section 222, but also on the groove wall on the side of the connecting wall 213 and the groove walls partially formed by the top wall 111 and the bottom wall 112, thus making the groove gradually expand in the circumferential direction (i.e., the closing direction around the bottom of the groove). This structural design allows the first support section 221 and the second support section 222 to have a larger initial rotation space when compressed along the second direction, avoiding contact or interference between the groove walls in the early stage of compression, thereby extending the stroke of the structural folding stage. Meanwhile, because the groove wall extends continuously at an inclined angle from the bottom to the opening, it can gradually contract inward along a preset geometric path during compression, making the deformation process more stable and controllable, effectively avoiding force jumps or structural instability caused by local abrupt changes. In addition, the gradual increase in circumferential dimensions also helps to improve the adaptability of the groove under multi-directional loads, enabling it to maintain good buffering performance even when subjected to non-perpendicular impacts.

[0077] In the first groove 231 and the second groove 232, the inner groove wall formed by the first support segment 221 and the second support segment 222 is a support groove wall 241; the support groove wall 241 extends inclinedly from the bottom of the groove to the top of the groove relative to a third direction. Further, in the first groove 231 and the second groove 232, the two support groove walls 241 of each groove extend inclinedly from the bottom of the groove to the top of the groove from opposite ends along the first direction. Specifically, the two support groove walls 241 in the first groove 231 are respectively formed by the inner surface of their corresponding first support segment 221. These two support groove walls 241 are close to each other at the bottom of the groove. As they extend upward along the third direction (i.e. towards the top wall 111), they gradually extend outward inclinedly towards opposite ends of the first direction—one forward and one backward—thereby making the opening width of the first groove 231 gradually increase from the bottom of the groove to the top of the groove in the first direction. Similarly, the two support groove walls 241 in the second groove 232 are formed by the inner surface of the corresponding second support section 222. They also start from the bottom of the groove and extend outward from the front and rear ends in the first direction, so that the second groove 232 also presents an expansion shape from narrow to wide in the first direction.

[0078] In the first groove 231 and the second groove 232, the inner groove wall formed by the connecting wall 213 is the connecting groove wall 242. The connecting groove wall 242 extends obliquely from the bottom of the groove to the top of the groove in a third direction. This oblique extension makes the groove wall formed by the connecting wall 213 inside the first groove 231 and the second groove 232 not vertical or concave, but outward, thus forming a funnel-shaped or flared groove outline together with the supporting groove wall 241 and the wall groove wall 243. Further, the two connecting groove walls 242 of the connecting wall 213 extend obliquely from opposite ends of the bottom of the groove to the top of the groove along a second direction. Specifically, the connecting groove wall 242 facing the first groove 231 starts from the bottom of the groove and extends obliquely outward (i.e., away from the center of the body 100) towards the top wall 111; while the connecting groove wall 242 facing the second groove 232 starts from the same bottom of the groove and extends obliquely outward towards the bottom wall 112. Thus, the connecting wall 213 is narrowest at the bottom of the groove and opens up towards the top wall 111 and the bottom wall 112 at the top of the groove, forming a geometric shape that is symmetrical and expands towards each other.

[0079] In the first groove 231 and the second groove 232, the inner groove wall formed by the top wall 111 and the bottom wall 112 is a wall groove wall 243; the wall groove wall 243 extends obliquely from the bottom of the groove to the top of the groove in a third direction relative to the top of the groove. This oblique extension causes the groove wall formed by the top wall 111 inside the first groove 231 and the groove wall formed by the bottom wall 112 inside the second groove 232 to be in an outwardly flared shape, thus forming a funnel-shaped or trumpet-shaped groove outline together with the supporting groove wall 241 and the connecting groove wall 242. Furthermore, in the top wall 111 and the bottom wall 112, the respective wall groove walls 243 extend obliquely from the bottom of the groove to the top of the groove along opposite ends in a second direction. The wall 243 of the first groove 231 starts from the bottom of the groove and extends outward (i.e., away from the center of the body 100) towards the top wall 111; while the wall 243 of the second groove 232 starts from the same bottom of the groove and extends outward towards the bottom wall 112. Thus, the inner surfaces of the top wall 111 and the bottom wall 112 in their respective groove areas are not vertical or concave, but rather open upward, downward, and outward respectively, so that the first groove 231 and the second groove 232 also exhibit an expanding configuration in the second direction.

[0080] Reference Figure 1In the first groove 231 and the second groove 232, the corresponding support groove wall 241 and connecting groove wall 242 form an angled transition at their junctions. This angled transition is not a smooth curved surface connection, but rather forms a clear, continuous ridge line at the junction of the support groove wall 241 and the connecting groove wall 242, constituting a concave or convex geometric angle. This angled structure plays a crucial role in guiding deformation during the component's compression: when the first support segment 221 or the second support segment 222 rotates inward about the connecting wall 213 as a pivot, the deformation first concentrates at this angle, making it a hinged area that preferentially bends or folds. The portions of the first support section 221 and the second support section 222 used to form the groove edges of the first groove 231 and the second groove 232 are configured as conical ridges, specifically a first ridge 251 and a second ridge 252. These conical ridge structures extend continuously along the groove edges, with a cross-section exhibiting a sharp or smoothly transitioned triangular profile. The ridge line protrudes outwards from the body 100, while the two inclined surfaces smoothly or at an angle connect with the support groove wall 241 and the adjacent groove wall, respectively. The first ridge 251 is located in the top region of the first support section 221 near the opening of the first groove 231, and the second ridge 252 is located in the bottom region of the second support section 222 near the opening of the second groove 232. Furthermore, the portion of the connecting wall 213 used to form the groove edges of the first groove 231 and the second groove 232 is configured as a conical ridge, specifically a third ridge 253, which is shared by the first groove 231 and the second groove 232. The third ridge 253 extends along the middle of the connecting wall 213 in a third-direction direction, and its ridge line simultaneously forms the common boundary of the first groove 231 and the second groove 232 on the inner side. The tapered cross-section of the third ridge 253 forms a high-rigidity longitudinal stiffener at the connecting wall 213, which can maintain the geometric stability of the connecting wall 213 during compression and also serve as a common pivot for the synchronous rotation of the first support section 221 and the second support section 222. Since the first groove 231 and the second groove 232 share this ridge, their openings can symmetrically close around the third ridge 253 when compressed, effectively avoiding the problem of asynchronous movement of the upper and lower grooves caused by the deformation of the connecting wall 213, thereby improving the deformation coordination and energy dissipation efficiency of the overall structure.

[0081] In addition, refer to Figure 1The first sidewall 211 and second sidewall 212 of each of the two adjacent support modules 200 cooperate with the top wall 111 and bottom wall 112 to form a third recess 233 along a third direction. Specifically, the second sidewall 212 of the preceding support module 200 and the first sidewall 211 of the following support module 200 are opposite to each other in a first direction. Together with the commonly connected top wall 111 and bottom wall 112, they enclose a hollow cavity independent of the first recess 231 and the second recess 232. This cavity is the third recess 233. The third recess 233 is also recessed into the body 100 along a third direction, and its opening faces the first or second side of the body 100. The overall configuration corresponds to the first recess 231 and the second recess 232.

[0082] In one preferred embodiment, the first sidewall 211 and the second sidewall 212 constituting the third groove 233 are connected along a first direction to divide the third groove 233 into a fourth groove and a fifth groove along a second direction. Specifically, the first sidewall 211 and the second sidewall 212 between two adjacent support modules 200 are not separate from each other, but are connected to each other or integrally formed at a certain position in the first direction to form a partition wall extending along the first direction and located in the middle of the third groove 233 in the second direction. This partition wall divides the originally continuous third groove 233 into two independent cavities in the second direction: the part located between the top wall 111 and the partition wall constitutes the fourth groove, and the part located between the bottom wall 112 and the partition wall constitutes the fifth groove.

[0083] In this embodiment, the circumferential dimension of the third groove 233 gradually increases from the bottom to the top. Specifically, the inner groove wall formed by the first sidewall 211 and the second sidewall 212 in the third groove 233 is the sidewall groove wall 244; the sidewall groove wall 244 extends obliquely from the bottom to the top of the groove relative to the third direction, so that the third groove 233 is open from the bottom to the opening. This open configuration makes the third groove 233 present an outwardly expanding funnel or funnel shape in its overall outline. The oblique extension of the sidewall groove wall 244 is not perpendicular to the surface of the body 100, but starts from the bottom of the groove and gradually expands outward toward the first or second side of the body 100, thereby forming a geometric transition from narrow to wide in the third direction. This structural design endows the third groove 233 with good initial compliance during compression: when the top wall 111 and the bottom wall 112 approach each other along the second direction, the first side wall 211 and the second side wall 212 of the adjacent support module 200 can move inward synchronously along the third direction, and the side wall groove wall 244 undergoes controllable bending, so that the groove width of the third groove 233 gradually decreases, achieving effective energy dissipation. Since the tilt angle of the side wall groove wall 244 changes continuously at different heights, its bending stiffness also gradually increases with the compression stroke. In the initial stage, due to the large tilt angle and long effective lever arm, the required driving force is small, and the damping is gentle; as the compression deepens, the tilt angle decreases, the side wall groove wall 244 tends to be vertical, and the structural stiffness increases rapidly, thus providing sufficient support reaction force in the later stage.

[0084] Furthermore, the first groove 231 and the second groove 232 can be closed structures at the bottom of the groove, or in this embodiment, the first groove 231 and the second groove 232 penetrate the body 100 along a third direction at the bottom of the groove. Further, the third groove 233 penetrates the body 100 along a third direction at the bottom of the groove. Moreover, the body 100 has a first side and a second side facing away from each other along a third direction; the first side and the second side are provided with support modules 200 opposite each other along a third direction. With this arrangement, the opposing support modules 200 of the first side and the second side are interconnected through the penetrating bottom of the groove.

[0085] Reference Figure 5The sole 300 involved in this embodiment adopts the aforementioned cushioning support component. The length direction of the sole 300 is the first direction of the cushioning support component, and the thickness direction is the second direction. The size of the support module 200 in the second direction increases and then decreases from the front to the rear of the sole 300. Specifically, in the forefoot area of ​​the sole 300 (corresponding to the toes to the metatarsals), the height of the support module 200 along the second direction (i.e., the thickness direction) is relatively small, making the overall structure of this area thinner and more flexible. This facilitates good flexural compliance during push-off or gait rolling, improving flexibility and naturalness of wear. As the position transitions towards the arch area, the size of the support module 200 in the second direction gradually increases, reaching its maximum value in the arch to heel area. This provides a longer cushioning stroke and higher structural stiffness in these critical areas that bear large impact loads, effectively absorbing the high-energy impact at the moment of landing and preventing contact failure due to excessive compression. Subsequently, the size of the support module 200 was slightly reduced from the rear of the arch to the end of the heel to avoid the heel area being too stiff, thus balancing cushioning comfort and landing stability.

[0086] Furthermore, referring to Figure 5 and Figure 6 In the support module 200, the line connecting the bottoms of the first groove 231 and the second groove 232, relative to the second direction, initially slopes backward from bottom to top from the front end to the rear end of the sole 300, transitions to being parallel to the second direction, and then slopes forward from bottom to top. The line connecting the bottoms refers to a virtual straight line connecting the bottoms of the first groove 231 and the second groove 232. Since the first groove 231 is located on the top wall 111 side and the second groove 232 is located on the bottom wall 112 side, this line extends spatially along the thickness direction of the body 100 and may exhibit an inclined state in the thickness direction. In the forefoot region of the sole 300, the line connecting the bottoms of the grooves in the same support module 200 slopes backward from front to back and from bottom to top. This means the bottom of the second groove 232 is closer to the front of the sole 300 than the bottom of the first groove 231. In other words, in the forefoot region, if viewed from front to back along the length of the sole 300, the bottom of the second groove 232 is slightly ahead of the bottom of the first groove 231 in the length direction, causing the line connecting the two grooves to slope from the lower front to the upper rear. In the arch region, the line connecting the grooves is basically parallel to the second direction, meaning the bottoms of the first groove 231 and the second groove 232 are at approximately the same position along the length of the sole 300, and the line connecting them is perpendicular to the plane of the sole 300, with no significant forward or backward offset. In the heel area, the groove bottom connection line slopes forward from bottom to top, that is, the groove bottom of the first groove 231 is closer to the front end of the sole 300 than the groove bottom of the second groove 232, so that the connection line slopes from the lower back to the upper front.

[0087] Reference Figure 7 , Figure 8 and Figure 9 The simulation results of the sole 300 involved in this embodiment are shown. The simulation results show that, in different stages of simulating foot impact, the stress distribution inside the cushioning support component exhibits a clear nonlinear progressive response characteristic, fully verifying its design goal of initial soft cushioning and subsequent rigid support. Among these, Figure 7 This demonstrates the stress distribution during the initial impact phase. At this time, the stress value in the contact area between the sole 300 and the ground (mainly located at the heel) is relatively low, with blue and green as the dominant colors. This indicates that the component has low stiffness during the initial compression phase, and the energy is mainly dissipated through the structural folding and wall bending of the first groove 231 and the second groove 232, achieving a gentle and efficient initial cushioning. Figure 8 This corresponds to the mid-stage of the impact process. The stress concentration area begins to expand towards the middle section of the sole 300 (arch position), and the color extends to most of the sole 300, indicating that as the compression increases, the deformation of the support module 200 enters the middle section, and the groove openings of some grooves have begun to narrow, with the structural stiffness gradually increasing to cope with the continuously increasing impact force. Figure 9 This reflects the stress distribution at the end of the impact. At this time, the stress peak appears in the forefoot and arch area, but the overall color is still relatively light, indicating that the 300 sole still has good cushioning effect, can effectively prevent the failure of the sole, and smoothly transfer the remaining impact force to the foot.

[0088] Example 2 Reference Figure 2 The difference between Embodiment 2 and Embodiment 1 is that the first groove 231 has a top wall groove 234 recessed along the second direction at the top wall 111; the second groove 232 has a bottom wall groove 235 recessed along the second direction at the bottom wall 112. Specifically, in the area of ​​the top wall 111 corresponding to the edge of the groove opening of the first groove 231, the top wall groove 234 is formed by recessing inward along the second direction (i.e., the thickness direction of the body 100); correspondingly, in the area of ​​the bottom wall 112 corresponding to the edge of the groove opening of the second groove 232, the bottom wall groove 235 is also formed by recessing inward along the second direction. These two grooves are spatially connected to the first groove 231 and the second groove 232, respectively, together forming a deeper and more open composite recessed structure.

[0089] Reference Figure 6 In the shock-absorbing support component of this embodiment, the second groove 232 has a notch 236 penetrating the bottom wall 112 along the second direction at the bottom wall 112 position. Specifically, the notch 236 is located in the area of ​​the bottom wall 112 corresponding to the edge of the groove of the second groove 232, and completely penetrates the bottom wall 112 along the second direction (i.e., the thickness direction of the body 100), so that the second groove 232 forms an open structure at the bottom wall 112, directly communicating with the bottom outer side of the body 100.

[0090] Example 3 Reference Figure 3 The difference between Embodiment 3 and Embodiment 2 is that the portion of the connecting wall 213 used to form the groove edges of the first groove 231 and the second groove 232 is configured as a platform-shaped third ridge 253, which is shared by the first groove 231 and the second groove 232. Specifically, based on Embodiment 2, this embodiment adjusts the geometry of the connecting wall 213 at the groove edge: instead of using a conical ridge structure, the connecting wall 213 is designed as a platform-shaped ridge structure with a flat top surface in the groove edge area shared by the first groove 231 and the second groove 232. That is, the top of the third ridge 253 is an approximately horizontal or slightly arc-shaped platform, and its two sides smoothly or at an angle transition to the inner groove walls of the first groove 231 and the second groove 232, respectively.

[0091] Example 4 Reference Figure 4 The difference between Embodiment 4 and Embodiment 3 is that the line connecting the bottoms of the first groove 231 and the second groove 232 is inclined relative to the second direction. As mentioned before, the line connecting the bottoms refers to the virtual straight line connecting the bottoms of the first groove 231 and the second groove 232. In Embodiment 3, this line is usually designed to be parallel or approximately perpendicular to the second direction (i.e., the thickness direction of the body 100) to ensure that the upper and lower grooves can fold inward synchronously and symmetrically when compressed. In this embodiment, the line connecting the bottoms is specifically designed to be inclined relative to the second direction. This inclination is not random, but is oriented according to the specific area and functional requirements of the component. For example, in the heel area of ​​the sole 300, the line connecting the bottoms can be inclined backward from bottom to top, that is, the bottom of the second groove 232 is slightly ahead of the bottom of the first groove 231 in the first direction; while in the forefoot area of ​​the sole 300, the line connecting the bottoms can be inclined forward from bottom to top, that is, the bottom of the first groove 231 is slightly ahead of the bottom of the second groove 232 in the first direction. The core purpose of this tilting design is to guide the support module 200 to deform in a directional manner under pressure. When the groove bottom line tilts backward, the support module 200 tends to fold backward (i.e., towards the heel) initially under pressure, thereby extending the cushioning stroke at the moment of heel strike and allowing the impact force to be absorbed more fully along the rolling direction of the foot. Conversely, when the groove bottom line tilts forward, the support module 200 tends to fold forward (i.e., towards the toes), which matches the biomechanical characteristics of the foot rolling from back to front when the forefoot pushes off the ground, helping to improve propulsion efficiency and agility.

[0092] In at least one embodiment, a buffer support component includes a body 100; the body 100 extends along a first direction and has opposing top walls 111 and bottom walls 112 along a second direction; at least one support module 200 is arranged between the top walls 111 and bottom walls 112 along the first direction; the first direction is perpendicular to the second direction; the support module 200 includes a first side wall 211, a second side wall 212, and a connecting wall 213; the first side walls 211 and the second side walls 212 are arranged along the first direction, and their two ends in the second direction are respectively connected to the top wall 111 and the bottom wall 112; the connecting wall 213 connects the first side wall 211 and the second side wall 212 along the first direction; the first side walls 211 and the second side walls 212 are separated by the connecting wall 213. A first support section 221 and a second support section 222 are formed along the third direction of the boundary. The top wall 111, the two first support sections 221 and the connecting wall 213 enclose a first groove 231 recessed along the third direction. The bottom wall 112, the two second support sections 222 and the connecting wall 213 enclose a second groove 232 recessed along the third direction. The first groove 231 and the second groove 232 are arranged along the third direction. The third direction is perpendicular to the first direction and the second direction. The groove edge formed by the two first support sections 221 in the first groove 231 opens from the top wall 111 toward the bottom wall 112. The groove edge formed by the two second support sections 222 in the second groove 232 opens from the bottom wall 112 toward the top wall 111.

[0093] When the component is subjected to initial pressure along the second direction, the groove edges of the first groove 231 open from the top wall 111 toward the bottom wall 112, and the groove edges of the second groove 232 open from the bottom wall 112 toward the top wall 111. This opposing opening configuration allows the grooves to contract and fold inward along the third direction when initially subjected to pressure. Specifically, when the top wall 111 and the bottom wall 112 approach each other, the first support segment 221 and the second support segment 222 rotate relative to each other about the connecting wall 213, the groove widths of the first groove 231 and the second groove 232 decrease, and the groove walls tilt inward and converge. During this process, energy is mainly dissipated by driving the rotation of the support segments around the connecting wall 213 and the bending deformation of the groove walls. Because the bending deformation of the groove walls and the rotation of the support sections require less resistance to overcome in the initial stage, the component exhibits low stiffness in the early stages of compression. It can complete the initial cushioning stroke with a small force under large displacement, thus transforming the instantaneous impact into a gradual buffering process and improving comfort during initial contact. As the compression increases, the openings of the first groove 231 and the second groove 232 continuously narrow, the rotation angle of the support sections gradually increases, and the distance between the groove walls continuously decreases. When the openings narrow to a certain extent, or the inner surfaces of the groove walls begin to contact each other, or the rotation of the support sections is geometrically constrained and approaches its limit position, the force required for further compression increases non-linearly. At this point, the component's mechanical mode shifts from primarily structural folding to primarily structural compaction and material compression, resulting in increased stiffness and entering a high-support mechanical stage. This stage can resist larger impact forces, preventing the component from failing due to excessive compression, thus ensuring support safety during movement. Conventional hollow columnar structures are prone to overall instability or disordered lateral buckling under compression, leading to unpredictable cushioning performance. In this application, the opposing opening configuration of the two grooves provides a clear deformation path under pressure: the first support segment 221 and the second support segment 222 rotate symmetrically inward about the connecting wall 213 as the center line, and the first groove 231 and the second groove 232 contract synchronously, causing the entire support module 200 to converge inward along a third direction, ensuring the stability and controllability of the deformation process and avoiding torsional or shear failure of the structure. The connecting wall 213, as the shared boundary of the first support segment 221 and the second support segment 222, acts as a geometric constraint and force transmission pivot during deformation, ensuring coordinated movement of the support segments on both sides and further enhancing the structure's resistance to instability. Furthermore, the first groove 231 and the second groove 232 are recessed along a third direction, and the first side wall 211 and the second side wall 212 extend along a first direction, giving the component differentiated stiffness characteristics in the three orthogonal directions: the first direction, the second direction, and the third direction.When the component is subjected to non-perpendicular impacts, such as complex loads with longitudinal or lateral components, the sidewalls extending along the first direction provide longitudinal shear resistance, while the grooved structure recessed along the third direction provides lateral buffering capacity, enabling the component to maintain a stable mechanical response under multi-directional loads. Since the mechanical properties of the component primarily stem from the geometry of the support module 200 rather than material properties, this allows for functional customization. By parametrically adjusting the geometry of the support module 200 at different locations, such as the depth of the groove, the opening angle of the groove, and the thickness of the connecting wall 213, the initial stiffness, folding stroke, and support stiffness during the compaction stage at that location can be controlled. This allows for differentiated combinations of shock absorption and support performance in different areas of the same component, based on biomechanical requirements, achieving zoned functional design that is difficult to achieve with traditional homogeneous materials or simple structures.

[0094] In at least one embodiment, the circumferential dimensions of the first groove 231 and the second groove 232 gradually increase from the bottom of the groove to the top of the groove.

[0095] The circumferential dimensions of the first groove 231 and the second groove 232 gradually increase from the bottom to the top, giving the grooves a funnel-shaped or trumpet-shaped expansion configuration. When the component is under pressure, because the groove opening width is greater than the groove bottom width, the support section has more room to move during rotation, and the groove walls do not contact each other prematurely, resulting in a longer stroke during the structural folding stage and a gentler initial damping effect. At the same time, the gradual increase in circumferential dimensions causes the groove walls to have different inclination angles at different heights. This geometric gradient can guide the support section to fold layer by layer along a preset path under pressure, avoiding sudden force jumps caused by local buckling and improving the stability and controllability of the damping process.

[0096] In at least one embodiment, the inner groove wall formed by the first support segment 221 and the second support segment 222 in the first groove 231 and the second groove 232 is a support groove wall 241; the support groove wall 241 extends obliquely from the bottom of the groove to the top of the groove relative to the third direction.

[0097] The support wall 241 extends obliquely from the bottom to the top of the groove relative to a third direction. Under compression, the obliquely extended support wall 241 can undergo controllable bending deformation along its oblique direction. This bending direction coincides with the direction of groove opening contraction, allowing the rotation of the support section and the bending of the groove wall to form a coordinated deformation mode, resulting in higher energy dissipation efficiency. Simultaneously, the oblique angle results in a longer effective length of the groove wall in the initial stage of compression, requiring less force for bending deformation, further reducing initial stiffness. As the compression increases, the oblique angle of the groove wall gradually decreases, the effective length shortens, and the bending stiffness increases accordingly, enabling the component to remain flexible during the initial damping stage and provide sufficient stiffness during the support stage.

[0098] In at least one embodiment, in the first groove 231 and the second groove 232, the two supporting groove walls 241 of each groove extend obliquely from opposite ends of the bottom of the groove along the first direction toward the top of the groove.

[0099] The two supporting groove walls 241 extend obliquely from opposite ends of the groove bottom towards the groove top along the first direction, so that the first groove 231 and the second groove 232 are open in the first direction. When the component is subjected to an oblique impact with a component force in the first direction, the groove opening along the first direction can absorb the impact component in that direction by adjusting the distance between the groove walls, thus avoiding stress concentration caused by the oblique force being completely transmitted to the side wall.

[0100] In at least one embodiment, the inner groove wall formed by the connecting wall 213 in the first groove 231 and the second groove 232 is the connecting groove wall 242; the connecting groove wall 242 extends obliquely from the bottom of the groove to the top of the groove relative to the third direction.

[0101] The connecting groove wall 242 extends obliquely from the bottom to the top of the groove relative to a third direction, making the connecting wall 213 not only the interface of the support section, but also participating in the opening configuration of the groove itself. The oblique extension of the connecting groove wall 242 allows the connecting wall 213 to undergo a certain degree of bending deformation under pressure, providing additional deformation freedom for the contraction of the first groove 231 and the second groove 232. This design avoids the connecting wall 213 being too rigid and restricting the groove opening contraction, making the folding process of the groove smoother. At the same time, the oblique direction of the connecting groove wall 242 matches the oblique direction of the supporting groove wall 241, making the overall shape of the first groove 231 and the second groove 232 more coordinated, and the opening angle of the groove opening more uniform in the circumferential direction. This ensures that the groove can contract symmetrically and uniformly under pressure, avoiding uneven deformation caused by localized preferential folding.

[0102] In at least one embodiment, the two connecting groove walls 242 of the connecting wall 213 extend obliquely from opposite ends of the groove bottom along the second direction toward the groove top.

[0103] The two connecting groove walls 242 of the connecting wall 213 extend inclinedly from opposite ends along the second direction from the bottom of the groove towards the top of the groove, so that the first groove 231 and the second groove 232 also open towards each other at the connecting wall 213. When the component is under pressure, the connecting groove walls 242 on both sides of the connecting wall 213 can tilt inward symmetrically, guiding the first support section 221 and the second support section 222 to rotate symmetrically about the connecting wall 213 as the center line, so that the contraction process of the two grooves is kept synchronous, avoiding the situation where one side of the groove closes first while the other side lags behind.

[0104] In at least one embodiment, the inner groove wall formed by the top wall 111 and the bottom wall 112 in the first groove 231 and the second groove 232 is a wall groove wall 243; the wall groove wall 243 extends obliquely from the bottom of the groove to the top of the groove relative to the third direction.

[0105] The groove wall 243 extends obliquely from the bottom to the top of the groove in a third direction, so that the top wall 111 and bottom wall 112 inside the first groove 231 and the second groove 232 also participate in the opening configuration. This all-round oblique extension design makes the shape of the groove more regular, and the opening angle of the groove is consistent in all circumferential directions, ensuring that the folding behavior of the groove under pressure has a high degree of symmetry and predictability. At the same time, the obliqueness of the groove wall 243 causes the effective thickness of the top wall 111 and bottom wall 112 at the groove position to vary along the third direction. This thickness gradient can regulate the local stiffness of the top wall 111 and bottom wall 112 at this position, so as to match it with the rotational stiffness of the support section, avoiding the top wall 111 or bottom wall 112 being too stiff and causing the rotation of the support section to be hindered.

[0106] In at least one embodiment, in the top wall 111 and the bottom wall 112, the respective wall portion groove wall 243 extends obliquely from opposite ends of the bottom of the groove towards the top of the groove along the second direction.

[0107] The groove walls 243 of the top wall 111 and the bottom wall 112 extend obliquely from opposite ends of the groove bottom towards the groove top along the second direction, so that the first groove 231 at the top wall 111 and the second groove 232 at the bottom wall 112 also exhibit an opening shape along the second direction. This design allows the grooves to not only open in the third direction but also have an expanding configuration in the second direction. When the component is under pressure, this three-dimensional opening configuration can provide deformation space in both the second and third directions simultaneously, so that the folding of the groove is not limited to contraction in a single direction but can undergo complex deformation with multiple degrees of freedom. This allows the component to adapt to more complex load conditions and maintain stable shock absorption performance under non-uniform pressure distribution or multi-directional impact.

[0108] In at least one embodiment, the connection points of the corresponding supporting groove wall 241 and connecting groove wall 242 in the first groove 231 and the second groove 232 are angled transitions.

[0109] The junction of the supporting groove wall 241 and the connecting groove wall 242 features a bend, forming a clear geometric ridge between the two walls. This bend acts as a hinge point for preferential deformation under pressure, guiding the groove wall to bend in a controlled manner at that location. The bend transition concentrates deformation at the ridge, creating a clear folding path and making the groove's contraction process more orderly. When the component is under pressure, the supporting groove wall 241 and the connecting groove wall 242 first bend at the bend, causing the entire groove to contract according to a preset folding pattern. This prevents unexpected buckling of the groove wall at other locations, improving the controllability and repeatability of deformation.

[0110] In at least one embodiment, the first groove 231 is recessed at the top wall 111 along the second direction and is provided with a top wall groove 234; the second groove 232 is recessed at the bottom wall 112 along the second direction and is provided with a bottom wall groove 235.

[0111] The first groove 231 has a top wall groove 234 recessed at the top wall 111, and the second groove 232 has a bottom wall groove 235 recessed at the bottom wall 112, so that the grooves are recessed not only into the body 100 but also into the outer surface of the body 100. This design increases the total depth of the grooves, providing more space for the groove opening to shrink. When the component is under pressure, the top wall groove 234 and the bottom wall groove 235 can accommodate the portion that protrudes outward after the support section rotates, avoiding interference between the support section and the top wall 111 or the bottom wall 112 when the support section rotates at a large angle, allowing the grooves to achieve a larger amount of shrinkage and extending the stroke of the initial damping stage. At the same time, the presence of the top wall groove 234 and the bottom wall groove 235 reduces the stiffness of the top wall 111 and the bottom wall 112 at this position, making them more prone to local bending deformation to match the shrinkage of the grooves, and making the deformation of the entire support module 200 more coordinated.

[0112] In at least one embodiment, the second groove 232 has a notch 236 extending through the bottom wall 112 along the second direction at the bottom wall 112 position.

[0113] The second groove 232 has a through-hole 236 along the second direction at the position of the bottom wall 112, making the second groove 232 an open configuration at the bottom wall 112. Conventional components typically avoid through-hole openings in the bottom wall 112 to ensure its integrity and strength, as there is concern that the opening would weaken the load-bearing capacity of the bottom wall 112. This solution, by providing a through-hole 236 along the second direction at the position of the bottom wall 112 of the second groove 232, completely opens the bottom of the second groove 232. When the component is under pressure, the second support section 222 rotates inward about the connecting wall 213. If the bottom wall 112 were a closed structure, the rotation of the second support section 222 would be limited by the inner surface of the bottom wall 112, with an upper limit to the rotation angle. The through-hole design of notch 236 eliminates this limitation, allowing the second support section 222 to rotate freely towards the bottom wall 112 without being obstructed by the inner surface of the bottom wall 112. This results in a longer contraction stroke of the second groove 232, a larger displacement during the initial damping phase, and a more effective damping effect. Furthermore, the through-hole design of notch 236 reduces the amount of material used in the bottom wall 112 at that location. Given that the second groove 232 already provides sufficient support, reducing the weight of the bottom wall 112 further reduces the overall weight of the component, meeting the requirements of lightweight design.

[0114] In at least one embodiment, the first groove 231 and the second groove 232 penetrate the body 100 in a third direction at the bottom of the groove.

[0115] The first groove 231 and the second groove 232 penetrate the body 100 in a third direction at the bottom of the groove, forming a through hole that runs through the entire thickness of the component. The existence of the through hole eliminates the constraint of the groove bottom, allowing the first support section 221 and the second support section 222 to rotate without being obstructed by the groove bottom, enabling them to rotate at a larger angle and further extending the initial cushioning stroke. In addition, the through hole reduces the amount of material used, lowers the overall weight of the component, and reduces the burden on the sole 300 while ensuring cushioning support performance.

[0116] In at least one embodiment, the portions of the first support segment 221 and the second support segment 222 used to form the groove edges of the first groove 231 and the second groove 232 are configured as a tapered ridge-shaped first ridge 251 and a second ridge 252.

[0117] The first support segment 221 and the second support segment 222, used to form the edge of the slot, are configured as a first ridge 251 and a second ridge 252 in the shape of conical ridges. The sharp geometric shape of the conical ridges gives the edge of the slot a clear positioning line, which guides the support segment to rotate along the positioning line under pressure, ensuring the accuracy of the folding path. At the same time, the presence of the conical ridges increases the local stiffness of the edge of the slot, making it less prone to deformation in the early stages of pressure. Instead, the deformation is transferred to the support segment and the slot wall, so that energy dissipation is mainly achieved through the rotation of the support segment and the bending of the slot wall, avoiding structural failure caused by premature deformation of the slot edge.

[0118] In at least one embodiment, the portion of the connecting wall 213 used to form the groove edge of the first groove 231 and the second groove 232 is configured as a conical ridge-shaped third ridge 253, and the first groove 231 and the second groove 232 share the third ridge 253.

[0119] The portion of the connecting wall 213 used to form the edges of the first groove 231 and the second groove 232 is configured as a conical ridge-shaped third ridge 253, which is shared by both grooves. Under pressure, this third ridge coordinates the folding behavior of the two grooves, ensuring that the first support segment 221 and the second support segment 222 rotate symmetrically around the ridge line, keeping the contraction of the two grooves synchronized. Simultaneously, the conical ridge shape gives the connecting wall 213 high bending stiffness at this location, maintaining shape stability under pressure and providing a reliable pivot for the rotation of the support segments, preventing deviation of the folding path due to torsional deformation of the connecting wall 213.

[0120] In at least one embodiment, the portion of the connecting wall 213 used to form the groove edge of the first groove 231 and the second groove 232 is configured as a platform-shaped third ridge 253, and the first groove 231 and the second groove 232 share the third ridge 253.

[0121] The portion of the connecting wall 213 used to form the edge of the slot is configured as a platform-ridge-shaped third ridge 253, which is shared by both slots. The flat surface of the platform ridge enhances the compressive strength of the connecting wall 213 at this location, enabling it to withstand greater vertical pressure without local crushing. This ensures that the connecting wall 213 maintains its geometry under large impact loads, provides a stable pivot for the support section, and guarantees the support performance of the component under high load conditions.

[0122] In at least one embodiment, the first sidewall 211 and the second sidewall 212 of each of the two adjacent support modules 200 cooperate with the top wall 111 and the bottom wall 112 to form a third groove 233 recessed in the third direction.

[0123] The first sidewall 211 and second sidewall 212 of each of the two adjacent support modules 200 cooperate with the top wall 111 and bottom wall 112 to form a third groove 233 recessed along the third direction. When the component is under pressure, the third groove 233 can deform in conjunction with the first groove 231 and second groove 232, further dissipating energy through the contraction of its groove opening. At the same time, the existence of the third groove 233 means that the adjacent support modules 200 are not rigidly connected, but connected by a deformable groove structure. This flexible connection allows each support module 200 to deform relatively independently, avoiding excessive constraint on the deformation of one support module 200 by adjacent modules. This allows the entire component to achieve more uniform compression along the first direction when under pressure, improving the consistency of shock absorption performance.

[0124] In at least one embodiment, the first sidewall 211 and the second sidewall 212 constituting the third groove 233 are connected along a first direction to divide the third groove 233 into a fourth groove and a fifth groove along a second direction.

[0125] The first sidewall 211 and the second sidewall 212, which form the third groove 233, are connected along the first direction, dividing the third groove 233 into a fourth groove and a fifth groove along the second direction. This partitioning design allows the third groove 233 to form two independent sub-grooves in the second direction, each of which can independently contract and fold. When the component is under pressure, the fourth and fifth grooves can deform differently according to the difference in pressure distribution. For example, if the pressure on the top wall 111 is greater, the fourth groove will contract first; if the pressure on the bottom wall 112 is greater, the fifth groove will contract first. This zoned response capability allows the component to adapt to non-uniform pressure distribution and maintain a stable damping effect even under localized stress. At the same time, the connection point of the first sidewall 211 and the second sidewall 212 can act as a support point when under pressure, limiting excessive compression of the third groove 233 in the second direction and ensuring that the third groove 233 can still provide support during the compaction stage.

[0126] In at least one embodiment, the circumferential dimension of the third groove 233 gradually increases from the bottom of the groove to the top of the groove.

[0127] The circumferential dimension of the third groove 233 gradually increases from the bottom to the top, giving it the same expansion configuration as the first groove 231 and the second groove 232. This consistency ensures that the mechanical behavior of the third groove 233 under pressure is coordinated with that of the first groove 231 and the second groove 232. All three can begin folding under similar pressure levels and enter the compaction stage under similar compression, resulting in a smoother mechanical response curve for the entire component and avoiding abrupt force jumps caused by sudden changes in different grooves at different stages. Simultaneously, the gradual increase in circumferential dimension allows the third groove 233 to achieve progressive folding, extending the initial damping stroke and improving the damping effect.

[0128] In at least one embodiment, the inner groove wall formed by the first sidewall 211 and the second sidewall 212 in the third groove 233 is a sidewall groove wall 244; the sidewall groove wall 244 extends obliquely from the bottom of the groove to the top of the groove relative to the third direction, so that the third groove 233 is open from the bottom of the groove to the opening of the groove.

[0129] The sidewall 244 of the third groove 233, formed by the first sidewall 211 and the second sidewall 212, extends obliquely from the bottom to the top of the groove relative to a third direction, making the third groove 233 open from the bottom to the opening. This open configuration allows the third groove 233 to contract inward along a third direction when compressed, dissipating energy through the oblique bending of the sidewall 244 and the relative proximity of adjacent support modules 200. The obliquely extended sidewall 244 has low bending stiffness in the initial stage of compression, allowing the third groove 233 to begin contracting under a small force. This, combined with the folding of the first groove 231 and the second groove 232, provides gentle initial damping. As the compression increases, the oblique angle of the sidewall 244 decreases, the bending stiffness increases, and the contraction resistance of the third groove 233 increases accordingly, increasing the stiffness of the component in this stage. This, in conjunction with the compaction stage of the first groove 231 and the second groove 232, provides support performance.

[0130] In at least one embodiment, the third groove 233 extends through the body 100 in a third direction at the bottom of the groove.

[0131] The third groove 233 extends through the body 100 in a third direction at the bottom of the groove, so that the third groove 233, like the first groove 231 and the second groove 232, has a through hole. This through design allows the third groove 233 to contract without obstruction when under pressure, and the side wall 244 can tilt freely inward without being restricted by the bottom of the groove, achieving a greater amount of contraction.

[0132] In at least one embodiment, the line connecting the bottoms of the first groove 231 and the second groove 232 is inclined relative to the second direction.

[0133] The line connecting the bottoms of the first groove 231 and the second groove 232 is inclined relative to the second direction, so that the bottoms of the two grooves are not on the same horizontal plane, but are arranged at an angle. This inclined design gives the support module 200 a tendency to deform under pressure, which can guide the component to fold preferentially in a specific direction. When the component is applied to the sole 300, by adjusting the inclination direction of the groove bottom connection, the component can have differentiated cushioning characteristics in the front-to-back or inside-out directions. For example, if the groove bottom connection is inclined from front to back, the component has a longer cushioning stroke at the heel and higher support stiffness at the forefoot, which can match the biomechanical characteristics of heel-first strike and forefoot-last push-off during exercise, improving the adaptability of cushioning performance to sports needs.

[0134] In at least one embodiment, the body 100 has a first side and a second side that are opposite to each other along a third direction; the first side and the second side are provided with support modules 200 at positions opposite to each other along the third direction.

[0135] The main body 100 has a first side and a second side facing away from each other along a third direction, and support modules 200 are provided opposite to each other on the two sides along the third direction. This design enables the component to have a cushioning structure on both sides of the third direction, providing symmetrical support for both sides of the third direction. When the component is applied to the inner or outer side of the sole 300, the support modules 200 on the first and second sides can respectively cope with lateral forces from the inner and outer sides, preventing the sole 300 from rolling inward or outward. At the same time, the support modules 200 arranged opposite to each other on the two sides can deform symmetrically under pressure, keeping the mechanical response of the component in the third direction balanced, avoiding the overall structural tilt caused by excessive deformation on one side, and improving the stability and predictability of the cushioning process.

[0136] In at least one embodiment, a shoe sole 300 employs a cushioning component based on any one of technical solutions one to twenty-two.

[0137] The cushioning support component itself possesses non-linear, progressive shock absorption and support performance. When applied to the sole 300, it dissipates the impact force experienced by the wearer during exercise, reducing damage to the knee and ankle joints. Simultaneously, the cushioning support component can be strategically placed according to the needs of different areas of the sole 300. For example, it can be used in the high-stress areas of the heel or arch to specifically enhance the cushioning performance in these areas, while other areas can utilize a conventional structure. This allows for a zoned functional design of the sole 300, ensuring the performance of key components while controlling the overall weight and cost of the sole 300. Furthermore, the structural design of the cushioning support component makes it durable, extending the lifespan of the sole 300 and preventing the rapid loss of cushioning performance that occurs with conventional soles under prolonged pressure.

[0138] In at least one embodiment, the length direction of the sole 300 is the first direction of the cushioning support component, and the thickness direction of the sole 300 is the second direction of the cushioning support component; the size of the support module 200 in the second direction increases and then decreases from the front end to the rear end of the sole 300.

[0139] The length direction of the sole 300 represents the first direction of the cushioning support component, while the thickness direction represents the second direction. The dimension of the support module 200 in the second direction increases and then decreases from the front to the rear of the sole 300. The forefoot requires high flexibility to adapt to flexion movements during exercise; a smaller dimension in the second direction results in a thinner overall thickness and lower stiffness of the cushioning support component at this location, making it easier to bend. The arch and heel bear greater impact forces and require stronger support; a larger dimension in the second direction allows the cushioning support component at these locations to have a longer folding stroke and higher compaction stiffness, providing more adequate cushioning and more solid support. This gradient dimension design along the length direction enables the sole 300 to achieve differentiated mechanical properties in different locations, meeting the different biomechanical needs of the forefoot, arch, and heel.

[0140] In at least one embodiment, the line connecting the bottom of the first groove 231 and the second groove 232 in the support module 200 is inclined from bottom to top and backward relative to the second direction from the front end to the rear end of the sole 300, then transitions to being parallel to the second direction, and then transitions to being inclined from bottom to top and forward.

[0141] In the support module 200, the line connecting the bottoms of the first groove 231 and the second groove 232, relative to the second direction, initially slopes backward from bottom to top from the front end to the rear end of the sole 300, transitions to being parallel to the second direction, and then transitions to slope forward from bottom to top. This change in slope direction gives the support module 200 different deformation tendencies at different positions on the sole 300. At the heel position, the backward slope of the groove bottom line causes the support module 200 to tend to fold backward under pressure, conforming to the forward rolling tendency of the foot when the heel strikes, guiding the impact force to be transmitted and dissipated along the rolling direction of the foot, and improving the comfort of heel cushioning. At the arch position, the parallelity of the groove bottom line to the second direction causes the support module 200 to fold vertically under pressure, providing stable vertical support and maintaining the shape of the arch. At the forefoot position, the groove bottom line is tilted forward, causing the support module 200 to tend to fold forward when under pressure. This can coordinate with the forward propulsion action of the foot when the forefoot pushes off the ground, making the cushioning deformation consistent with the direction of movement, thus improving the rolling sensation and propulsion efficiency during movement.

[0142] In at least one embodiment, a shoe includes an upper and a sole 300 based on any one of technical solutions 23 to 25, the upper being attached to the sole 300.

[0143] The outsole 300 provides cushioning and support, and when attached to the upper, it transfers the cushioning effect of the outsole 300 to the foot. At the same time, the upper wraps around the foot and works in conjunction with the outsole 300 to fix the foot in position, preventing the foot from sliding inside the shoe during exercise and improving stability.
