Description

Technical Field

[0001] This utility model relates to the field of shoe soles, specifically to a biomechanically based zoned cushioning shoe sole structure. Background Technology

[0002] As the component that directly contacts the ground and bears the core functions of foot support and cushioning, the structural design of the shoe sole has always been a key focus of the industry. Currently, the design of athletic shoe soles still faces many challenges in balancing structure and function, making it difficult to fully adapt to the biomechanical characteristics of the human body during exercise.

[0003] Common athletic shoe soles typically use a single cushioning material (such as EVA foam) or a full-length air cushion structure, which has three major drawbacks: low cushioning efficiency: the impact force transmission path is singular when heel strikes, failing to specifically absorb high-intensity impacts to the calcaneus area; high energy loss: the material's deformation resistance is high when the forefoot flexes, leading to energy loss during push-off; and unbalanced support: the arch area lacks a dynamic anti-torsional structure, easily causing plantar fascia fatigue. While some segmented sole designs divide functional areas, the structures of each area are simply stacked, failing to consider the biomechanical characteristics of the human body. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings and provide a biomechanically based zoned cushioning sole structure. This structure enhances the cushioning effect of the sole by setting different zones based on biomechanics during cushioning, thus solving the technical problem that existing technologies are unable to fully adapt to the biomechanical characteristics of human movement in terms of cushioning.

[0005] The objective of this utility model is achieved through the following means:

[0006] A biomechanically based zoned cushioning sole structure includes a sole surface. A forefoot area is located on one side of the lower surface of the sole surface, and a heel area is located on the other side. An arch area is located between the forefoot and heel areas on the lower surface of the sole surface. An anti-torsion plate is embedded within the arch area. The forefoot area is filled with honeycomb-shaped cushioning units, and biomimetic trabecular supports are inserted between the honeycomb-shaped cushioning units. Flexible elastic sheets connect the honeycomb-shaped cushioning units. Foam columns are inserted within the heel area, and connecting ribs are fused between the foam columns. The inner walls of each honeycomb-shaped cushioning unit have drainage channels.

[0007] Furthermore, the anti-torsion plate is X-shaped, with both sides of the anti-torsion plate connected to the outside of the forefoot and heel areas. The number of anti-torsion plates is 1-3 sets. The X-shaped structure can better conform to the physiological curve of the arch of the foot. The connection between the two sides and the forefoot and heel areas can form an overall support frame, enhance the anti-torsion continuity of the sole, prevent the arch of the foot from shifting due to torsion during exercise, reduce the pulling sensation of the plantar fascia, and improve overall stability.

[0008] Furthermore, all the flexible springs are arc-shaped, and each of the outer ends of the flexible spring is equipped with a welded protrusion between it and the single honeycomb structure of the honeycomb buffer unit. The arc-shaped structure is more suitable for the deformation trajectory when the forefoot is bent, which can reduce the resistance when bending and make the forefoot move more flexibly. The welded protrusion can strengthen the connection between the spring and the honeycomb structure, avoid the spring from falling off due to long-term deformation, and extend the service life of the buffer structure in the forefoot area.

[0009] Furthermore, the number of bionic trabecular bone supports is 3-6 sets, and each set of bionic trabecular bone supports is equipped with a buffer support column. The number of buffer support columns on one side is 4-8 sets, and the buffer support columns are all obliquely set. The design of bionic trabecular bone supports combined with oblique buffer support columns can construct a three-dimensional support network. The obliquely set support columns can disperse the force on the forefoot in multiple directions, avoiding local force concentration. Together with the support, it can improve the structural strength of the forefoot area, which can not only cope with the push-off force during exercise, but also maintain the softness of the cushioning.

[0010] Furthermore, the density of the foam columns decreases from the inside to the outside, all foam columns are inclined, and all connecting ribs are arc-shaped. Extending ribs connect the inner sides of the foam columns between the connecting ribs. The design of decreasing foam column density, inclined arrangement, and arc-shaped connecting ribs and extending ribs allows the force on the heel to gradually transition from the center to the outside, avoiding concentrated impact. The inclined arrangement matches the force direction of the heel landing, improving cushioning efficiency. The arc-shaped connecting ribs and extending ribs can drive more foam columns to deform together, making the impact force more evenly distributed and reducing the harshness of heel landing.

[0011] Furthermore, the bionic trabecular bone support is woven from shape memory alloy wires, and its surface is coated with a piezoelectric ceramic coating. The outer surface of the foam column is covered with a nanofiber reinforcement layer. Regarding the design of the materials, coatings, and foam column covering of the bionic trabecular bone support, the shape memory alloy wire woven support can flexibly return to its original position according to the deformation of the forefoot, maintaining support stability; the piezoelectric ceramic coating can sense deformation and assist in adjusting the cushioning force; the nanofiber reinforcement layer can enhance the wear resistance and tear resistance of the foam column, reduce structural wear after long-term use, and extend the overall service life of the sole.

[0012] The beneficial effects of this invention are as follows: By adding a honeycomb-shaped cushioning unit in the forefoot area in conjunction with a flexible spring, the deformation mode of the traditional honeycomb unit is changed. When the foot bends and exerts force, the honeycomb-shaped cushioning unit changes from hard compression deformation to smooth deformation through the coordination of flexible rotation and deformation, reducing the feeling of resistance when exerting force. At the same time, the bionic trabecular bone support constructs a three-dimensional support system for the forefoot area, avoiding insufficient support caused by excessive deformation. This allows the impact force on the forefoot to be transmitted to all sides through the bionic trabecular bone support when performing actions such as jumping and sudden stopping, reducing the stress burden on local units and improving the quality of the sole. The combination of the foam column array and connecting ribs makes the impact evenly distributed, reducing the harsh impact when the heel lands, and preventing deformation fatigue of local foam columns due to repeated concentrated stress. Thus, the cushioning effect of the sole is improved through the setting of different zones. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] In this embodiment, refer to Figures 1-6The specific implementation of the biomechanically based zoned cushioning sole structure includes a bottom surface 1, a forefoot area 2 on one side of the lower surface of the bottom surface 1, a heel area 4 on the other side of the lower surface of the bottom surface 1, an arch area 3 between the forefoot area 2 and the heel area 4 on the lower surface of the bottom surface 1, an anti-torsion plate 5 embedded inside the arch area 3, a honeycomb-shaped cushioning unit 6 filled inside the forefoot area 2, a biomimetic trabecular support 7 inserted between the honeycomb-shaped cushioning units 6, and flexible elastic sheets 9 connected between the honeycomb-shaped cushioning units 6, a foam column 12 inserted inside the heel area 4, a connecting rib 13 fused between the foam columns 12, and a drainage groove 11 opened on the inner wall of the honeycomb-shaped cushioning unit 6;

[0022] The anti-torsion plate 5 is X-shaped. Both sides of the anti-torsion plate 5 are connected to the outside of the forefoot area 2 and the rearfoot area 4. There are 1-3 sets of anti-torsion plates 5. The flexible springs 9 are all arc-shaped. Welding protrusions 10 are installed between the outer ends of the flexible springs 9 and the single honeycomb structure of the honeycomb buffer unit 6.

[0023] By adding a honeycomb-shaped cushioning unit 6 to the forefoot area 2 in conjunction with a flexible spring 9, the deformation mode of the traditional honeycomb unit is changed. When the foot bends and exerts force, the honeycomb-shaped cushioning unit 6 changes from hard compression deformation to smooth deformation through the coordination of flexible rotation and deformation, reducing the feeling of resistance when exerting force. At the same time, the bionic trabecular bone support 7 constructs a three-dimensional support system for the forefoot area 2, avoiding insufficient support caused by excessive deformation. This allows the impact force on the forefoot to be transmitted to the surroundings through the bionic trabecular bone support 7 when performing actions such as jumping and sudden stopping, reducing the stress burden on local units and improving the quality of the sole.

[0024] The number of bionic bone trabecular support 7 is 3-6 sets, and buffer support columns 8 are installed between the bionic bone trabecular support 7. The number of buffer support columns 8 on one side is 4-8 sets. The buffer support columns 8 are all set at an angle. The density of the foam columns 12 decreases from the inside to the outside. The foam columns 12 are all set at an angle. The connecting ribs 13 are all set in an arc shape. The inner side of the foam columns 12 is connected to the connecting ribs 13 with extension ribs 14.

[0025] By combining the array of foam columns 12 with the connecting ribs 13, the impact is evenly distributed, reducing the harsh impact when the heel lands. At the same time, it avoids deformation and fatigue of local foam columns 12 due to repeated concentrated force, thus improving the cushioning effect of the sole through the setting of different zones.

[0026] The bionic trabecular bone scaffold 7 is woven from shape memory alloy wires. The surface of the bionic trabecular bone scaffold 7 is coated with a piezoelectric ceramic coating, and the outer surface of the foamed column 12 is covered with a nanofiber reinforcement layer.

[0027] This design, through the addition of a honeycomb-shaped cushioning unit 6 in the forefoot area 2 in conjunction with a flexible spring 9, changes the deformation mode of traditional honeycomb units. When the foot bends and exerts force, the honeycomb-shaped cushioning unit 6 changes from hard compression deformation to a smooth deformation achieved through the synergy of flexible rotation and deformation, reducing the feeling of resistance when exerting force. At the same time, the bionic trabecular support 7 constructs a three-dimensional support system for the forefoot area 2, avoiding insufficient support caused by excessive deformation. This allows the impact force on the forefoot to be transmitted to all sides through the bionic trabecular support 7 when performing actions such as jumping and sudden stopping, reducing the stress burden on local units and improving the quality of the sole. In addition, the combination of the array of foam columns 12 and the connecting ribs 13 makes the impact evenly distributed, reducing the harsh impact when the heel lands, and preventing deformation fatigue of local foam columns 12 due to repeated concentrated stress. Thus, the cushioning effect of the sole is improved through the setting of different zones.

[0028] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
