Description

Technical Field

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

[0002] Footwear products consist of an upper and a sole structure. The upper can be formed from suitable materials to accommodate, secure, and support the foot against the sole structure. The upper can work with laces, Velcro, or other fasteners to adjust the fit of the upper around the foot. The bottom portion of the upper, closest to the foot, is attached to the sole structure.

[0003] The sole structure comprises different components arranged and connected in layers between the ground and the upper. At the bottom layer of the sole structure is the outsole, which provides abrasion resistance and traction to the ground; it may be formed of rubber or other suitable materials. Above the outsole is the midsole, which provides cushioning and rebound for the foot and is at least partially formed of a polymer foam material that deforms upon pressure applied to it by the foot to cushion the foot by reducing the reaction force of the ground. A footbed may be defined on the upper surface of the midsole, the contour of which may be configured to conform to the contour of the sole surface of the foot. The sole structure may also include an insole or insole for enhancing comfort, which is fixedly or detachably attached to the upper surface of the midsole and located within the cavity defined by the midsole and the upper.

[0004] In current shoe sole structures, to improve the longitudinal bending rigidity, flat and rigid plate-like components with longitudinal stiffness are embedded in the sole structure. These plate-like components can be made of carbon fiber, nylon, TPU, or other suitable materials. Typically, this type of shoe sole structure with an embedded plate consists of a single, seamless plate that conforms to the midsole contour. However, in practical use, this type of embedded plate suffers from excessive bending rigidity, resulting in poor comfort during wear and foot traffic. Furthermore, the large amount of material used leads to high manufacturing costs. To address this, existing technologies have proposed designing the embedded plate with a perforated structure, that is, creating through-holes at specific locations on the original plate-like component to reduce bending rigidity and improve user comfort. However, this perforated structure cannot provide sufficient longitudinal bending rigidity in scenarios requiring higher rigidity. Therefore, current embedded components used to provide longitudinal bending rigidity in shoe sole structures struggle to achieve a good balance between performance and comfort. Utility Model Content

[0005] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide an embedded hollow component for shoe soles, shoe soles and shoes, wherein the embedded hollow component can achieve a good balance between performance and comfort for shoe soles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Technical Solution 1: An embedded hollow component for a shoe sole, comprising: an outer frame whose shape is adapted to the shoe sole, which corresponds to the forefoot, arch, and heel portion formed sequentially from front to back on the shoe sole, and forms an inner edge and an outer edge corresponding to the inner and outer sides of the shoe sole, and a front edge and a rear edge corresponding to the front and rear ends of the shoe sole; and located within the outer frame: at least two first ribs arranged sequentially in an inward and outward direction, extending forward from the rear edge to the arch portion, and then bending inward to connect to the inner edge located on the forefoot portion; at least one second rib located outside the first ribs and arranged sequentially in an inward and outward direction, extending forward from the rear edge, with the outermost second rib connecting to the arch portion and the forefoot portion. The outer edge at the boundary; at least five third ribs arranged sequentially in the front-back direction, extending obliquely outward from the inner edge to connect to the outer edge or the front edge; at least one fourth rib located behind the third ribs and arranged sequentially in the front-back direction, extending obliquely backward from the inner edge to connect to the outer edge; at least two fifth ribs located in front of the first ribs and arranged sequentially in the front-back direction, extending obliquely backward from the inner edge, with the rearmost fifth rib connecting to the outer edge located at the boundary between the arch and the forefoot; wherein the perforation formed by the intersection of the first, second, third, fourth, and fifth ribs has a smooth transition at the corner positions.

[0008] Technical Solution 2 based on Technical Solution 1: The connection point between the rearmost third rib and the inner edge is located at the boundary between the arch and the heel, and the connection point between the third rib and the outer edge is located at the arch.

[0009] Technical Solution 3 based on Technical Solution 2: The connection between the third rib located at the second rearmost position and the inner edge is located in the arch of the foot, and the connection between the third rib and the outer edge is located in the forefoot.

[0010] Technical Solution 4 based on Technical Solution 3: The third rib at the rearmost position intersects with the fourth rib at the frontmost position, and the intersection of the two is located inside the first rib at the innermost position.

[0011] Technical Solution 5 based on Technical Solution 4: Each of the first ribs starts from the inner position of the rear edge, extends obliquely outward, then bends forward and extends forward, then bends outward and extends forward to the front position of the arch of the foot, and then bends inward until it connects to the inner edge.

[0012] Technical solution six based on technical solution five: Each of the second ribs starts from the outer position of the rear edge, extends inward at an angle, then bends forward and extends forward, then bends outward and extends forward to the outer edge.

[0013] Technical solution seven based on technical solution one: The outer frame also includes at least one sixth rib, which is located behind the third rib and arranged sequentially in the front-back direction, and extends outward from the innermost first rib to connect to the outer edge.

[0014] Technical solution eight based on technical solution one: The outer frame has relatively independent first toe and second toe arranged sequentially from the inside to the outside at the front end of the forefoot. The outer periphery of the first toe and the second toe is formed by the front edge of the outer frame, and their rear ends are connected to the fifth rib at the frontmost position. The front end of the first toe is located behind the front end of the second toe in the front-back direction.

[0015] Technical solution nine based on technical solution eight: the outer side of the first toe is the first edge, and the inner side of the second toe is the second edge. The first edge and the second edge both extend obliquely from front to back and from left to right to form the front edge of the outer frame, and the two are spaced at a preset distance in the inward and outward directions to form a first notch.

[0016] Technical Solution 10 based on Technical Solution 1: The outer edge of the outer frame is disconnected between the connection point of the third rib located second rearward and the outer edge, and the boundary between the arch and the forefoot, to form a second notch.

[0017] Technical solution eleven based on technical solution one: It also includes a rear frame, the rear frame being connected to the rear edge of the outer frame, and having a seventh rib inside it that starts from its rear end, connects to the rear edge, and is connected to a first rib.

[0018] In addition, this utility model also provides technical solution twelve: a shoe sole, which includes a body formed by the cooperation of an outsole and a midsole, characterized in that an embedded hollow component for the shoe sole as described in technical solutions one to eleven is provided between the outsole and the midsole, or inside the midsole.

[0019] In addition, this utility model also provides technical solution thirteen: a shoe, characterized in that it includes a sole as described in technical solution twelfth, and an upper is attached to the sole.

[0020] 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:

[0021] Technical solution one provides an embedded hollow component for a shoe sole, the core of which consists of an outer frame adapted to the shape of the sole and multiple sets of ribs (first to fifth ribs) arranged in a specific pattern inside. The first rib extends longitudinally from the heel to the inner side of the forefoot, providing the main longitudinal support; the second rib is located outside the first rib, also providing longitudinal support, and connects to the outer edge of the boundary between the arch and the forefoot, enhancing lateral stability; the third rib extends obliquely from the inner side to the outer side, spanning the component, resisting torsion and providing lateral connection; the fourth rib extends obliquely from the inner side to the outer side, cooperating with the third rib to further enhance torsional resistance and rear stability; the fifth rib is located in the forefoot area, extending obliquely from the inner side to the outer side, and connects to the outer edge of the boundary between the arch and the forefoot, strengthening the structural stability of the forefoot area and controlling bending.

[0022] This hollow component achieves a balance between lightweight and high-performance mechanical support through a specific rib layout. It can construct a structure with high strength and high rigidity with less material consumption. This significantly reduces the weight and production cost of the component itself, while specifically meeting the complex mechanical needs of the sole during exercise and optimizing the transmission path (force flow) of foot pressure, providing sufficient comfort during daily wear.

[0023] In terms of longitudinal performance, the hollowed-out component provides crucial bending resistance through first and second ribs extending in the front-to-back direction. These longitudinal ribs, like main beams in the structure, impart significant longitudinal stiffness to the sole during the transition from mid-support to push-off. This stiffness transforms the sole into an effective propulsive lever, helping to efficiently transfer the force generated during push-off along a pre-defined longitudinal force flow path to the ground, reducing energy loss during excessive flexing of the sole. This improves the efficiency and energy feedback of movements such as running or walking, providing the user with a stronger propulsive experience.

[0024] Meanwhile, this component, through a carefully arranged network of third, fourth, and fifth diagonal ribs, greatly enhances the torsional stability and overall structural integrity of the sole. These diagonal ribs connect the inner and outer edges or longitudinal ribs, forming multiple stable mechanical units that effectively guide and distribute the force flow of complex torsional loads and shear forces generated during the walking cycle (especially during impact and mid-stance). This superior torsional rigidity is crucial for maintaining the correct biomechanical posture of the foot during movement. By controlling the distribution of force flow, it helps control excessive pronation or supination, enhances midfoot stability, and provides synergistic support for the arch support function provided by the first rib, ensuring safety and balance during movement.

[0025] Furthermore, this perforated component does not solely pursue rigidity; its design also fully considers the flexibility and comfort required for natural foot movement. Through the perforated areas between the ribs and the connection and direction design of specific ribs (such as the fifth rib in the forefoot area), this component allows the sole to undergo necessary and controlled flexion in specific areas (such as the metatarsophalangeal joint in the forefoot). This design avoids the stiffness of traditional rigid plates, allowing the force flow corresponding to the natural flexion and extension movements of the foot during the push-off phase to pass smoothly, improving the sole's responsiveness and adaptability to changes in ground conditions, thereby significantly enhancing wearing comfort and the smoothness and naturalness of the gait.

[0026] Compared to solid, ordinary embedded plate components, the embedded hollow component provided by this technical solution does not offer uniform, excessively high rigidity. Instead, it achieves the on-demand distribution of mechanical properties through the layout of ribs. The hollow structure itself gives the sole a certain degree of flexibility, avoiding the stiffness of solid plates and greatly improving wearing comfort and the natural bending of the sole. Furthermore, compared to simply perforated hollow plates, it is not a simple, unstructured perforation of a flat plate, but rather the construction of a highly optimized rib network. Among them, the first and second ribs are mainly arranged longitudinally and precisely extend from the heel to a specific area of ​​the forefoot, which can effectively guide the main longitudinal force flow, providing strong longitudinal bending stiffness. This solves the problems of insufficient support and poor energy feedback that may exist in simple hollow plates, ensuring efficient power transmission and propulsion. At the same time, the diagonal arrangement of the third, fourth, and fifth ribs constitutes a strong anti-torsional support system. By effectively managing lateral and torsional force flow, it significantly improves the sole's ability to resist torsional deformation and enhances stability during movement, which is usually difficult to achieve effectively with simple perforated designs. This targeted rib layout allows force flow to be precisely guided to the reinforced structure, enabling the component to provide specific mechanical properties (such as longitudinal stiffness and torsional stiffness) in key directions and areas that are no less than or even better than those of a solid plate, even when it is hollow.

[0027] More importantly, the orientation, connection points, and relative positions of each set of ribs are optimized to create the best force transmission path. Impact forces can be effectively absorbed and dispersed along specific ribs, while propulsive forces can be concentrated and guided along other ribs. This precise control of force flow is the core mechanism for achieving a balance between high performance and comfort.

[0028] Furthermore, technical solution one effectively avoids stress concentration caused by sharp inner corners by ensuring a smooth transition at the corners of the perforated holes formed by the intersecting ribs. When the sole is subjected to repeated impacts and bending loads, stress concentration is a major cause of structural fatigue failure. The smooth corner design allows force flow to be redirected and distributed more smoothly at the rib connections, significantly reducing local peak stress. This greatly improves the fatigue resistance and overall durability of the component, ensuring a longer service life and higher reliability for this lightweight, high-performance structure.

[0029] Therefore, the core advantage of this technical solution lies in its innovative and complex rib geometry and optimized structural details (such as smooth transitions at the edges and corners), which successfully overcomes the inherent contradiction between performance, comfort, and durability. Unlike solid plates that sacrifice comfort for rigidity, or simple perforated plates that may sacrifice necessary support, stability, or durability for flexibility, this solution achieves an organic combination of lightweight, high strength, high rigidity (in a specific direction), excellent stability, good flexibility, comfort, and enhanced durability through structural functional zoning (different ribs undertake different mechanical tasks) and optimized force flow paths (the specific direction and connection points of the ribs precisely guide plantar pressure). This design not only meets the needs of high-performance athletic shoes for support, stability, and energy return, but also takes into account the user's requirements for wearing comfort and natural gait, providing a more comprehensive, balanced, and reliable solution.

[0030] In Technical Solution Two, the detailed structure of the components is further precisely defined, specifically specifying the connection point of the rearmost third rib: its inner end connects to the boundary line between the arch and the heel, while its outer end connects to the outer edge of the arch area. The boundary between the arch and the heel, and the entire arch area, are key areas for bearing weight, absorbing impact, and maintaining foot stability, especially during the initial landing phase to the mid-support phase of walking or running. Technical Solution Two precisely deploys the rearmost third rib in this core area transitioning from heel weight-bearing to arch support. This rib, extending diagonally from the inner rear boundary to the outer arch area, forms a diagonal support structure. Its orientation and connection point design enable it to effectively and directly counteract excessive collapse or torsional deformation (e.g., excessive pronation) that may occur in the posterior and inner parts of the arch during this transition phase. When the user's foot lands and begins to bear weight, this specially positioned rib can intervene earlier and more effectively, providing crucial diagonal support to help maintain the shape of the posterior arch and stabilize the force transmission between the medial and lateral sides. Therefore, this technical solution, through the refined design of the rib layout in key areas, further optimizes the sole's ability to stabilize and control the posterior arch during the landing and early support phases, providing stronger protection for the user and reducing the risk of fatigue or injury that may result from insufficient or unstable arch support, making the overall support effect more reliable and precise.

[0031] In Technical Solution 3, a specific connection method for the third rib, located second to rearward, further optimizes the foot's biomechanical transmission path and stability. The medial connection point of the third rib is located in the arch, while the lateral connection point extends to the forefoot. This additional technical feature precisely positions a key diagonal support structure in the critical transition area connecting the midfoot (arch) and forefoot (forefoot). During the gait cycle, as the body's center of gravity shifts from the arch to the forefoot in preparation for the final push-off, the foot undergoes complex biomechanical changes, including potential torsion and redistribution of forces on the medial and lateral sides. This rib, diagonally connecting the medial arch to the lateral forefoot, provides crucial structural support during this critical midfoot-to-forefoot transition. It effectively enhances the connection stiffness and torsional resistance from the mid-arch to the lateral forefoot region, helping to suppress excessive foot deformation or instability that may occur during this phase, ensuring a smooth and efficient transmission of force from the arch forward. Furthermore, this rib provides direct support from the medial arch to the lateral forefoot region. During the push-off motion, the stability of the forefoot, especially the lateral region, is crucial for generating effective thrust. This design in Technical Solution 3 strengthens the platform stability of the lateral forefoot through structural connections, helping to guide push-off force and preventing unnecessary lateral deflection or collapse of the forefoot during the process. Therefore, building upon the enhanced arch stability of Technical Solution 2, Technical Solution 3 further refines the entire midfoot to forefoot biomechanical control chain by precisely positioning another key diagonal rib immediately in front of it. This allows the embedded components to more accurately match and support the complex mechanical demands of the foot during dynamic movement, from weight-bearing to propulsion, ultimately improving the overall athletic performance and stability of the sole.

[0032] In technical solution four, it is specified that the rearmost third rib (whose connection point has been precisely defined in solution two to strengthen the posterior arch) intersects with the frontmost fourth rib (which extends obliquely from the inner edge to the rear outer side), and this intersection point is explicitly located inside the innermost first rib. The core of this additional feature lies in the synergistic enhancement effect brought about by the structural intersection and the precise location of the intersection point. First, the intersection of the two ribs itself forms a structural node. At this node, two load-bearing members with different orientations converge and support each other, which can significantly improve the local stiffness and deformation resistance of the intersection point and its surrounding area. Compared with non-intersecting independent ribs, the intersecting structure can more effectively disperse and resist the complex stresses acting on the area, especially shear forces and local torsional forces. In this example, the third rib extending forward and outward and the fourth rib extending backward and outward form an "X"-shaped intersection, a geometry that naturally has high structural stability. Second, and more importantly, is the location of the intersection point—located inside the innermost first rib. The first rib is the main longitudinal support structure on the inner side of the component, roughly corresponding to the medial longitudinal arch of the foot. Placing this reinforced intersection node further inward of the main longitudinal support, extending into the inner edge of the core arch support area, is crucial because this area is where stress concentrates and excessive collapse deformation is prone to occur when the foot bears weight, especially during pronation. Therefore, technical solution four introduces a reinforced structural node formed by the intersection of the key third and fourth ribs in the core stability zone of the posterior medial arch (inner side of the innermost first rib), achieving highly focused and reinforced local support in this area. This intersection point directly acts on the location most in need of controlling pronation and maintaining arch shape, greatly enhancing the component's ability to resist excessive collapse of the medial arch and control pronation. This plays a very important and positive role in improving gait stability and efficiency during walking or running, and preventing foot and lower limb injuries that may be caused by excessive pronation, making the entire embedded component's support system more complete and efficient.

[0033] Technical Solution Five further specifies the exact shape of the first rib's extension path. The contour and arch structure of the inner side of the human foot are not simple geometric shapes, but rather complex curves and undulations. The multiple bending paths of the first rib in Technical Solution Five allow it to more closely conform to and surround the physiological structures of the inner side of the foot, especially the shape of the medial longitudinal arch. This improved shape matching helps achieve a more uniform pressure distribution and more natural force transmission, enhancing the fit and comfort of the component with the foot. Secondly, compared to a straight path, this bending path significantly affects the stress distribution and local stiffness of the rib. While still providing the main longitudinal bending stiffness overall, the bending can be used to guide stress flow, preventing excessive stress concentration in sensitive areas such as connection points. Simultaneously, the bent section exhibits different deformation characteristics under stress than the straight section, potentially introducing differentiated stiffness or a certain degree of controllable elasticity in different sections of the rib. This design helps absorb impacts of specific frequencies, achieving optimized energy storage and release characteristics during the push-off phase. More importantly, this path design, especially its "first expand outward (sloping outward, bending outward) then contract inward (bending inward)" characteristic, significantly enhances the wrapping support for the medial arch area. When the first rib forms an outward-protruding arc in the arch area and then converges to connect to the medial side of the forefoot, it not only provides a bottom "beam" support but also forms a structure that can wrap around and "lift" the medial arch from the side. This greatly enhances the ability to maintain the shape of the medial arch, especially when the arch is under pressure, it can more effectively resist its tendency to collapse inward and downward. This, together with the intersection point reinforcement support provided by technical solution four in the core area of ​​the medial posterior arch, forms a three-dimensional support system that echoes each other front and back, combining internal and external support, making the protection of the entire medial longitudinal arch more comprehensive and solid.

[0034] Technical Solution Six further specifies the exact extension path shape of the second rib. Similar to the medial arch, the lateral aspect of the foot (including the lateral longitudinal arch region) also has its unique physiological curve. The "inward-adjusting then outward" path design of the second rib allows it to better conform to and adapt to the complex contours of the lateral aspect of the foot. This superior shape matching helps achieve a more uniform pressure distribution on the lateral side, reduces local pressure points, improves wearing comfort, and promotes more natural force transmission. The bending path of the second rib alters its mechanical behavior as a load-bearing component. The presence of the bend can guide stress flow, avoiding destructive stress concentration at lateral connection points or stress-sensitive areas. Simultaneously, by adjusting the curvature and length of the bending segment, the local stiffness or elastic response of different parts of the second rib can be finely adjusted, thereby optimizing the impact absorption capacity or energy feedback characteristics of the lateral side to meet the needs of different sports scenarios. The second rib's path, starting from the posterior lateral edge and first adducting then abducting, effectively surrounds and supports key structures on the lateral side of the foot, especially the lateral longitudinal arch and related skeletal structures. The geometric shape formed by this path creates a wrap-around support frame on the outer side, which can more effectively resist excessive pronation of the foot during movement. Technical solutions five and six work together to achieve synergistic optimization of the main longitudinal support systems on both the inner and outer sides of the embedded hollow component. They are designed with complex, functionally specific bending paths to address the biomechanical needs of the inner and outer sides, respectively. This design not only improves the support, stability, and comfort performance on each side, but more importantly, it establishes a balanced and coordinated mechanical support system. The first inner rib and the second outer rib work together to more comprehensively and precisely control the mechanical behavior of the entire foot during dynamic movement, ensuring the stability and efficiency of the foot throughout the entire process from landing to push-off.

[0035] Technical Solution 7 introduces at least one sixth rib to improve and enhance the overall structural performance of the component, particularly in terms of lateral stability in the rear region. The sixth rib is located behind the existing third rib (i.e., in the rear of the arch or further back of the component), and its connection extends outward from the innermost first rib (the main longitudinal support structure on the inner side) until it connects to the outer edge. The sixth rib strengthens the mechanical connection between the main inner support structure (the first rib) and the outer boundary. When the sole is subjected to forces during movement, especially when the heel is subjected to impact loads or complex vertical and torsional loads during the mid-support phase, the sixth rib works effectively. Specifically, the sixth rib directly resists forces that may cause lateral expansion or contraction in the heel area, maintaining the width stability of the rear of the component and providing a more stable platform for the heel. By connecting the inner and outer sides, it helps to distribute impact forces or pressures acting on one side more evenly across the entire rear structure of the component, reducing stress concentration.

[0036] Technical Solution 8 specifies that, at the front end of the forefoot portion of the outer frame, two relatively independent toe portions (corresponding to the thumb area) and second toe portions (corresponding to the other toe areas) are arranged sequentially from the inside to the outside. The outer periphery of these two toe portions is formed by the front edge of the outer frame, and their rear ends are connected to the foremost fifth rib. A key feature is that the front end of the first toe portion is located behind the front end of the second toe portion in the anteroposterior direction. By dividing the front end of the forefoot into two relatively independent areas, the overall rigidity of this area is significantly reduced. During the push-off phase of walking or running, the toes need to perform independent flexion and extension movements, especially the thumb (first toe), which plays a crucial propulsive role. This separate design allows the first and second toe portions to flex and adapt to the ground to a certain extent independently, better conforming to the natural movement patterns of the toes. This avoids the restrictive feeling that may result from a traditional one-piece front end design, improving the flexibility and comfort of the forefoot. Furthermore, the front end of the first toe is located behind the front end of the second toe, which better adapts to the relatively posterior structural feature of the first metatarsal head of the human foot. Simultaneously, by providing a relatively independent, positionally adapted support area for the first toe and allowing for greater freedom of flexion and extension, this design helps maximize the propulsive efficiency of the big toe during the push-off phase. At the same time, the rear end connects to the fifth rib, ensuring the mechanical connection between these two independent toes and the main structure of the component, enabling the effective transmission of push-off force.

[0037] Technical Solution Nine further specifies the structure of the first and second toes, forming a first notch between them. This first notch, with its specific sloping edge, provides greater independent movement space for the first and second toes, allowing for a greater degree of relative bending and twisting, thus more fully releasing the flexibility of the forefoot and better accommodating the complex and delicate movements of the toes during exercise. The notch edge is designed to extend at a sloping angle. This sloping design, rather than a right angle or sharp corner, helps guide stress smoothly along the edge during bending or under load, avoiding sharp stress concentration points at the root of the notch. Avoiding stress concentration significantly improves the fatigue resistance and durability of the structure, preventing premature cracking or damage at the notch due to repeated bending. The sloping edge also helps to create a more natural transition shape during bending.

[0038] Technical Solution Ten further specifies a second notch on the outer edge. This second notch significantly reduces the local stiffness of the corresponding area, weakening the outer frame's resistance to stretching / compression along the edge direction, as well as its resistance to bending and torsion, thereby increasing the flexibility of that area. Furthermore, this second notch releases the constraint of the outer frame on the natural deformation of the key transition area on the outer side of the foot. During the gait cycle, especially during the transition from full weight-bearing to push-off, the outer side of the foot experiences some flexion and possibly slight torsion. A completely continuous and rigid outer frame might restrict this natural dynamic adjustment. The second notch in Technical Solution Ten allows for a greater degree of adaptive deformation of the outer edge of the sole at this specific location, more in line with the physiological movement patterns of the foot. Therefore, the second notch significantly improves wearing comfort, reducing the pressure or discomfort that may arise from an overly stiff or restrictive outer side of the sole, especially during prolonged exercise or activities requiring flexible foot movement. Secondly, it improves the sole's adaptability to subtle differences in individual foot shapes and uneven surfaces, allowing the sole to better conform to the foot and maintain stable contact with the ground.

[0039] In technical solution eleven, a rear frame is set, and a seventh rib is set in the rear frame. The seventh rib connects with a first rib in the direction, thereby forming a rearward-extending and more enveloping structure at the rear end of the hollow component. It can also cooperate with the first rib in the path of power transmission, further improving the mechanical response and energy transfer efficiency of the hollow component.

[0040] Technical solution twelve provides a shoe sole, comprising a body formed by the combination of an outsole and a midsole, with embedded hollow components as described in technical solutions one to eleven disposed between the two or within the midsole. Its technical effect lies in significantly improving the overall performance of the shoe sole in terms of longitudinal bending rigidity, stability, and comfort by integrating the embedded hollow components into the shoe sole structure.

[0041] Technical solution thirteen provides a shoe, including the sole described in technical solution twelve, with an upper attached to the sole. Its technical advantage lies in combining an optimized sole and upper to form a footwear product with superior overall performance, possessing longitudinal bending rigidity, comfort, and durability.

[0062] Embodiment 1 of this utility model relates to an embedded hollow component for shoe soles. This embedded hollow component can be disposed within the body of the shoe sole and provides enhanced structural strength. The embedded hollow component can be made of materials such as carbon fiber or nylon TPU, and its manufacturing method can be 3D printing or other feasible methods, such as hot pressing or injection molding. Products made with different materials and manufacturing methods will have different performance characteristics, but these differences only arise from the different materials and manufacturing methods within the same structure. Compared to conventional embedded components made with the same materials and manufacturing methods, such as solid plate-like components or plate-like components with through holes, the embedded hollow component of this embodiment still has good performance advantages and better wearing comfort.

[0063] Reference Figure 1 The embedded hollow component involved in this embodiment is made of carbon fiber material and manufactured by 3D printing.

[0064] The embedded hollow component includes: an outer frame 10 whose shape is adapted to the sole, which corresponds to the forefoot portion 11, the arch portion 12, and the heel portion 13 formed sequentially from front to back on the sole, and forms an inner edge 14 and an outer edge 15 corresponding to the inner and outer sides of the sole, and forms a front edge 16 and a rear edge 17 corresponding to the front and rear ends of the sole; and located within the outer frame 10: at least two first ribs 21, which are arranged sequentially in the inward and outward direction, extending forward from the rear edge 17 to the arch portion 12, and then bending inward to connect to the inner edge 14 located on the forefoot portion 11; at least one second rib 22, which is located outside the first ribs 21 and arranged sequentially in the inward and outward direction, extending forward from the rear edge 17, and the outermost second rib 22 connects to the boundary between the arch portion 12 and the forefoot portion 11. The outer edge 15; at least five third ribs 23 arranged sequentially in the front-back direction, extending obliquely outward from the inner edge 14 to connect to the outer edge 15 or the front edge 16; at least one fourth rib 24 located behind the third ribs 23 and arranged sequentially in the front-back direction, extending obliquely backward from the inner edge 14 to connect to the outer edge 15; at least two fifth ribs 25 located in front of the first rib 21 and arranged sequentially in the front-back direction, extending obliquely backward from the inner edge 14, with the rearmost fifth rib 25 connecting to the outer edge 15 located at the boundary between the arch portion 12 and the forefoot portion 11; wherein the perforation formed by the intersection of the first, second, third, fourth, and fifth ribs has a smooth transition at the corner position.

[0065] Specifically, the shape of the outer frame 10 is referenced. Figure 1 The outer frame 10 is a closed frame component that surrounds the entire body. Its outline is adapted to the shape of the sole and corresponds to the structure of the sole and the relationship between the sole and the human foot. From front to back, it is divided into the forefoot 11, the arch 12, and the heel 13. Figure 1 The three parts are clearly defined. Furthermore, the outer frame 10 also has an inner edge 14, an outer edge 15, a front edge 16, and a rear edge 17. Figure 1 The hollowed-out component in the design represents the right foot; therefore, its left side is the inner side, and its right side is the outer side. The area corresponding to the toes is the front edge 16, and the area corresponding to the heel is the rear edge 17. Figure 1 The image shows a first dividing point 31 and a second dividing point 32, which are the dividing points between the forefoot 11 and the arch 12, and the dividing point between the arch 12 and the heel 13, respectively.

[0066] Several ribs are provided within the outer frame 10. Based on the starting and ending positions, extension direction, etc., these ribs are divided into first rib 21, second rib 22, third rib 23, fourth rib 24 and fifth rib 25.

[0067] Among them, the first tendon 21 spans across the forefoot 11, the arch 12 and the heel 13, the second tendon 22 spans across the arch 12 and the heel 13, the third tendon 23 is distributed alone or spans across the forefoot 11 and the arch 12, the fourth tendon 24 spans across the arch 12 and the heel 13, and the fifth tendon 25 is distributed alone in the forefoot 11.

[0068] Furthermore, the connection point between the rearmost third rib 23 and the inner edge 14 is located at the boundary between the arch portion 12 and the heel portion 13, and its connection point with the outer edge 15 is located at the arch portion 12. The connection point between the second rearmost third rib 23 and the inner edge 14 is located at the arch portion 12, and its connection point with the outer edge 15 is located at the forefoot portion 11. The rearmost third rib 23 intersects with the frontmost fourth rib 24, and the intersection point is located inside the innermost first rib 21.

[0069] Furthermore, each of the first ribs 21 originates from an inward position on the rear edge 17, extends obliquely outward, then bends forward and extends forward, then bends outward and extends forward to the front of the arch portion 12, and then bends inward until it connects to the inner edge 14. Each of the second ribs 22 originates from an outward position on the rear edge 17, extends obliquely inward, then bends forward and extends forward, then bends outward and extends forward to the outer edge 15.

[0070] Specifically, in this embodiment, there are two first ribs 21, arranged sequentially along the inner and outer directions. However, due to the change in the extension direction of the first ribs 21, that is, the bending of the first ribs 21 at different locations, the two first ribs 21 in the forefoot 11 can be regarded as being arranged obliquely from the inner rear to the front and outer directions. Among them, the rear edge 17 is the starting position of the extension of the first ribs 21. The starting position of the innermost first rib 21 is at the position of the rear edge 17 near the inner edge 14 of the outer frame 10, and the starting position of the outermost first rib 21 is at the approximate middle position of the rear edge 17. Then the first ribs 21 extend obliquely outward, bend forward after reaching the middle position of the heel 13 in the front-back direction, and bend slightly outward at the boundary between the heel 13 and the arch 12. After reaching the upper position of the arch 12, they bend inward at a larger extent, and then extend smoothly to the inner edge 14 of the middle position of the forefoot 11.

[0071] There is one second rib 22, which is located between the outermost first rib 21 and the outer edge 15 of the outer frame 10, and its extension is roughly the same as the extension of the outer edge 15 of the outer frame 10 in the heel 13 and the arch 12. The second rib 22 starts from the rear edge 17 near the outer edge 15, bends forward along the shape of the outer edge 15, and reaches the outer edge at the boundary between the arch 12 and the forefoot 11.

[0072] There are five third ribs 23, all extending from the inner rear to the front and outer sides. The difference lies in the location: the three rearmost ribs 23 connect at one end to the inner edge 14 and the other end to the outer edge 15, while the two frontmost ribs 23 connect at one end to the inner edge 14 and the other end to the front edge 16. The rearmost rib 23 connects to the inner edge 14 at the boundary between the arch 12 and the heel 13, and connects to the outer edge 15 below the first boundary 31. It should be noted that due to the direction of inclination of the third ribs 23, the rearmost ribs 23 can be considered to be distributed along the front-back direction, while the ribs 23 in the forefoot 11 can be considered to be distributed along the inside-outside direction.

[0073] There is one fourth rib 24, which extends from the inner front to the outer rear. The connection position of the fourth rib 24 with the inner edge 14 is roughly the same as the connection position of the third rib 23, which is located second to rear, with the inner edge 14. The connection position of the fourth rib 24 with the outer edge 15 is located in the front position of the heel 13. Therefore, the fourth rib 24 intersects with the third rib 23, which is located in the rear position of the arch 12, near the second dividing point 32.

[0074] There are two fifth ribs 25, both extending from the inner front to the outer rear. Unlike the fourth rib 24, which has a rearward-protruding bend, the fifth rib 25 has a forward-protruding bend. Notably, the connection point between the rearmost fifth rib 25 and the outer edge 15 is roughly equivalent to the connection point between the second rib 22 and the inner edge 14, that is, the fifth rib 25 connects to the boundary between the forefoot portion 11 and the heel portion 13.

[0075] It should be understood that the term "extension" as used in this specification and claims does not mean that the product should be extended in the specified direction during actual manufacturing. Rather, it is merely a structural description of the arrangement of the various ribs and does not constitute a limitation on the specific manufacturing process.

[0076] In addition, the outer frame 10 also includes at least one sixth rib 26, which is located behind the third rib 23 and arranged sequentially in the front-back direction. It extends outward from the innermost first rib 21 to connect to the outer edge 15.

[0077] Specifically, there is one sixth rib 26. One end of the sixth rib 26 is connected to the first rib 21 located at the innermost side, and the other end is connected to the outer edge 15. However, since both the second rib 22 and the sixth rib 26 have a certain width, and the connection position of the rear end of the second rib 22 with the rear edge 17 is close to the outer edge 15, the sixth rib 26 can be regarded as the connection position between the second rib 22 and the rear edge 17 and the outer edge 15.

[0078] Reference Figure 1 The first rib 21, the second rib 22, the third rib 23, the fourth rib 24, the fifth rib 25, and the sixth rib 26 interweave to form multiple perforated holes that enclose the periphery in the circumferential direction and extend through the thickness direction on the embedded perforated component. The corners of these perforated holes have smooth transitions. For example, when these perforated holes are approximately quadrilateral, they have four corners that have a smooth, rounded transition structure rather than sharp angles.

[0079] This embodiment relates to an embedded hollow component for shoe soles. Through a specific rib layout, it achieves a balance between lightweight and high-performance mechanical support. It can construct a structure with high strength and high rigidity with less material consumption. This significantly reduces the weight and production cost of the component itself, while specifically meeting the complex mechanical needs of the shoe sole during exercise and providing sufficient comfort during daily wear.

[0080] Specifically, by precisely setting the connection point of the last third rib 23, the stability control of the posterior arch during the landing and early support phases is enhanced. By setting a specific third rib 23 connecting the medial side of the arch and the lateral side of the forefoot, the stability and force transmission of the midfoot to forefoot transition area are optimized. The specific third and fourth ribs 24 intersecting on the medial side of the first rib 21 strengthen the local support of the core area of ​​the medial arch, improving anti-pronation ability. The specific bending path of the first rib 21 enhances the fit and wrapping support effect of the medial arch. The specific bending path of the second rib 22 improves the fit and support stability of the lateral sole, helping to control eversion. The addition of a sixth rib 26 connecting the first rib 21 to the lateral edge 15 strengthens the lateral stability and structural integrity of the rear part of the component.

[0081] Furthermore, the first and second longitudinal ribs primarily guide the main propulsive force flow from the heel to the forefoot, providing efficient longitudinal stiffness and energy transfer. The third, fourth, and fifth diagonal ribs manage and disperse the lateral and torsional force flow generated during walking or running, effectively resisting torsional deformation and enhancing foot stability. This layout allows plantar pressure to flow along a pre-defined reinforced path, achieving on-demand distribution of mechanical properties. The corners of the perforated openings formed at the intersections of the ribs feature a smooth transition design, crucial for the smooth transmission of force. Sharp corners obstruct force flow and create stress concentration points, easily leading to fatigue failure. Smooth transitions allow for a more even distribution of force flow during turns, avoiding localized stress peaks. This not only ensures efficient and unobstructed force transmission throughout the component but also significantly improves the structure's fatigue resistance and overall durability, ensuring the reliability of the lightweight structure under repeated loads.

[0082] Example 2

[0083] Reference Figure 2 In Example 2, the outer frame 10 was adjusted at the front end of the forefoot portion 11 based on Example 1.

[0084] The outer frame 10 has a first toe portion 42 and a second toe portion 43 arranged sequentially from the inside to the outside at the front end of the forefoot portion 11. The outer periphery of the first toe portion 42 and the second toe portion 43 is formed by the front edge 16 of the outer frame 10, and their rear ends are connected to the fifth rib 25 located at the frontmost position. The front end of the first toe portion 42 is located behind the front end of the second toe portion 43 in the front-back direction.

[0085] Furthermore, the outer side of the first toe portion 42 is the first edge 44, and the inner side of the second toe portion 43 is the second edge 45. The first edge 44 and the second edge 45 both extend obliquely from front to back and from left to right to form the front edge 16 of the outer frame 10, and the two are spaced apart by a preset distance in the inward and outward directions to form the first notch 46.

[0086] Specifically, refer to Figure 2 In front of the foremost fifth rib 25 of the forefoot portion 11, a first toe portion 42 and a second toe portion 43 are formed. The first toe portion 42 and the second toe portion 43 are formed by the cooperation of the inner edge 14, the outer edge 15, the deformed front edge 16, and the connected foremost fifth rib 25. The inner side of the first toe portion 42 is the inner edge 14 of the frame, and the outer side is the first edge 44, which can be regarded as part of the front edge 16. Similarly, the inner side of the second toe portion 43 is the second edge 45, which can be regarded as part of the front edge 16, and the outer side is the outer edge 15 of the frame.

[0087] A first notch 46 is formed between the first toe portion 42 and the second toe portion 43, with a first edge 44 and a second edge 45 on its inner and outer sides, respectively. The front end of the innermost third rib 23 is connected to the front edge 16 of the first toe portion 42, and two perforations are formed between the inner edge 14 and the first edge 44. The front end of the second innermost third rib 23 is connected to the front edge 16 of the second toe portion 43, and two perforations are formed between the second edge 45 and the outer edge 15.

[0088] In this embodiment, the structure of the outer frame 10 at the forefoot portion 11 is adjusted by dividing the front end of the outer frame 10 into first and second toe portions 43 with different front and rear positions and relatively independent, thereby improving the flexibility of the forefoot and its adaptability to natural foot movements. By providing a first notch 46 with an inclined edge between the first and second toe portions 43, the independent bending ability of the forefoot is further enhanced and the stress distribution is optimized, thereby improving durability.

[0089] Example 3

[0090] Reference Figure 3 In Example 3, the outer frame 10 was adjusted on the outer edge 15 of the forefoot portion 11 based on Example 2.

[0091] The outer edge 15 of the outer frame 10 is interrupted at the junction of the third rib 23 (located second rearward) and the outer edge 15, and at the boundary between the arch portion 12 and the forefoot portion 11, forming a second notch 47. This second notch 47 significantly improves wearing comfort, reducing the pressure or discomfort that may arise from an overly stiff or restrictive outer sole, especially during prolonged exercise or activities requiring flexible foot movement. Secondly, it enhances the sole's adaptability to subtle differences in individual foot shapes and uneven surfaces, allowing the sole to better conform to the foot and maintain stable contact with the ground.

[0092] Example 4

[0093] Reference Figure 4 and Figure 5 Example 4 adds a rear heel frame 50 to Example 3. The rear heel frame 50 is connected to the rear edge 17 of the outer frame 10, and has a seventh rib 27 that starts from its rear end, connects to the rear edge 17, and connects to a first rib 21.

[0094] Specifically, the heel frame 50 is connected to the rear edge 17 of the outer frame 10, and its outer contour is roughly triangular in shape with a pointed end facing rearward. A seventh rib 27, which connects to the first rib 21, is provided on the inner side of its frame. And referring to… Figure 5The thickness of the rear frame 50 is less than the thickness of the outer frame 10 and each rib in front of it. By setting the rear frame 50, a structure that extends backward and has a better covering effect is formed at the rear end of the hollow component, and it can cooperate with the first rib 21 in the path of power transmission, further improving the mechanical response and energy transfer efficiency of the hollow component.

[0095] Among them, reference Figure 6 , Figure 6 The diagram illustrates a portion of the force transmission path of the embedded hollow component involved in Embodiment 4. Specifically, the red lines represent propulsive force flow, and the blue lines represent stabilizing and controlling force flow. A rearward-extending, more enveloping structure is formed at the rear end of the hollow component, which can cooperate with the first rib 21 in the power transmission path, further improving the mechanical response and energy transmission efficiency of the hollow component. This path clearly simulates the main force transmission process of the human body during walking or running, from heel strike (or midfoot support) to forefoot push-off. The red force flow is smoothly transmitted along the longitudinal structures such as the first and second ribs, indicating that these ribs effectively collect, guide, and concentrate the forward propulsive force. The longitudinal stiffness of the component ensures the efficient transmission of this force flow, reduces energy loss, and converts the force of foot push-off into effective ground reaction force, achieving strong propulsion. The blue force flow exhibits more oblique or lateral distribution. For example, in the arch and heel areas, there are oblique blue force flows connecting the inner and outer sides; there are also oblique force flows distributed in the forefoot area. These paths correspond to the layout of the third, fourth, and fifth diagonal ribs. The blue force flows represent the forces required to resist torsion and maintain balance during movement. When the foot strikes the ground with impact or when there is a tendency for inward or outward pronation during the support phase, these forces attempt to cause the sole to twist or deform laterally. The blue force flows in the diagram show that the network of diagonal ribs effectively intercepts, disperses, and manages these lateral and torsional force flows. They transmit forces from the inside to the outside (or vice versa), forming a stable support structure that resists unwanted deformation, thereby controlling excessive inward or outward pronation of the foot and ensuring gait stability and safety.

[0096] Furthermore, referring to Figure 7 , Figure 7 This is a schematic diagram of plantar force flow. Different colors represent different plantar pressures, with redder colors indicating higher pressure and purple colors indicating lower pressure. A line extending from the heel towards the forefoot represents the pressure trajectory from the initial force flow concentration area to the final force flow concentration area. Figure 7 It can be understood that the shape of the first rib 21 in the embedded hollow component involved in embodiments 1-4 of this utility model is adapted to the trajectory of the foot force flow, thereby constructing a structure from the first rib 21 to the other ribs through the connection of the first rib 21 with the other ribs. Figure 7 The efficient and direct flow structure of the seven points of force flow to the main longitudinal force flow channel ensures that the initial impact force can be stably received and smoothly introduced into the preset propulsion force flow path.

[0097] Example 5

[0098] Embodiment 5 of this utility model relates to a shoe sole, which adopts the embedded hollow component described in any one of Embodiments 1-4.

[0099] Specifically, the sole comprises a body formed by the outsole and midsole, with the aforementioned embedded hollow component disposed between the two or within the midsole. By integrating the embedded hollow component into the sole structure, the overall performance of the sole—including longitudinal bending rigidity, stability, and comfort—is significantly improved.

[0100] Furthermore, when the embedded hollow component involved in Embodiment 4 is used, the heel frame 50 of the hollow component will be exposed at the rear end of the sole, which improves the visual recognition when wearing the shoe and further enhances the protection and control of the wearer's heel in terms of structure.

[0101] Example 6

[0102] Embodiment 6 of this utility model relates to a shoe, including the sole described in Embodiment 5, with an upper attached to the sole. Thus, by combining the optimized sole and upper, a footwear product with superior overall performance is formed, possessing longitudinal bending rigidity, comfort, and durability.

[0103] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
