Description

Technical Field

[0001] This utility model relates to the field of footwear technology, and in particular to a composite board structure and a shoe midsole. Background Technology

[0002] High-performance athletic shoes (including road racing shoes, trail running shoes, basketball shoes, tennis shoes, etc.) prioritize lighter weight and higher rebound, thus widely using supercritical foam materials as midsole materials. However, this material also suffers from drawbacks such as poor interlayer tear resistance, poor torsional strength, and poor scratch resistance. This leads to a series of quality issues, commonly including sole breakage, sole delamination and tearing, sole surface damage, and delamination between the foam material and the carbon fiber plate. A few manufacturers use air cushioning to provide rebound performance, but these are also prone to damage and air leakage in outdoor off-road environments. Utility Model Content

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0019] like Figure 1 As shown, this utility model provides a composite plate structure, which includes a composite plate 1 and an elastomer ring 2. The elastomer ring 2 is a closed ring. The composite plate 1 is provided with a through hole 13. The elastomer ring 2 passes through the through hole 13 and is fixedly connected to the composite plate 1. The size of the elastomer ring 2 matches the diameter of the through hole 13. The aforementioned elastomer ring 2 includes an inner elastomer ring and an outer elastomer ring. The space formed by the aforementioned through hole 13 inside the aforementioned composite material 1 is an elastomer channel. The aforementioned inner elastomer ring is fixedly disposed in the aforementioned elastomer channel, and the length of the aforementioned inner elastomer ring is equal to the length of the aforementioned elastomer channel. The aforementioned outer elastomer ring is fixedly connected to the aforementioned inner elastomer ring, forming a fixed connection structure with the aforementioned composite material 1. The aforementioned composite board 1 includes multiple alternating elastic boards 11 and foam boards 12. Each elastic board 11 is fixedly connected to its adjacent foam board 12. The shape of each elastic board 11 is the same as the shape of each foam board 12.

[0020] For example, such as Figure 2 and Figure 3As shown, the composite board structure includes a composite board 1 and an elastomer ring 2. The composite board 1 comprises multiple alternating elastic boards 11 and foam boards 12, each elastic board 11 and foam board 12 being fixedly connected, and each elastic board 11 and each foam board 12 having the same shape. The connection between the elastic boards 11 and foam boards 12 can be achieved by water-soluble adhesive bonding. After bonding, a through hole 13 can be formed using a punching machine, and then the board can be cut into the required shape. The elastomer ring 2 is a closed ring and is fixedly connected to the composite board 1.

[0021] For example, such as Figure 4 As shown, the composite plate 1 has a vertically penetrating through hole 13. The elastomer ring 2 passes through the composite plate 1 via the through hole 13, thus achieving a fixed connection with the composite plate 1. The size of the elastomer ring 2 matches the diameter of the through hole 13, ensuring a fixed connection between the elastomer ring 2 and the composite plate 1.

[0022] For example, the aforementioned elastomer ring 2 may include an inner elastomer ring and an outer elastomer ring. The space formed inside the composite material 1 by the through hole 13 is an elastomer channel. The inner elastomer ring is fixedly disposed within the elastomer channel, and the length of the inner elastomer ring is equal to the length of the elastomer channel. The portion of the elastomer ring 2 disposed outside the composite material 1 is the outer elastomer ring. The outer elastomer ring and the inner elastomer ring are fixedly connected to form a closed elastomer ring 2, thereby achieving a fixed connection with the composite material 1.

[0023] Furthermore, the through hole 13 formed on the first surface of the composite board 1 is a first through hole, and the through hole 13 formed on the second surface of the composite board 1 is a second through hole. The diameter of the first through hole is the same as the diameter of the second through hole. The first surface and the second surface are two opposite surfaces of the composite board 1.

[0024] For example, if the through hole 13 is vertically penetrating, then a perforation is formed on the top and bottom surfaces of the composite board 1, namely the first perforation and the second perforation, and the diameter of the two perforations is the same, indicating that the shape of the elastomer channel is a regular cylindrical shape, and the inner elastomer ring 2 is completely fitted with the elastomer channel.

[0025] In this utility model Figures 1-4 This is merely an example and is not intended to limit the shape of the embodiments of this application. The composite board 1 described above can be cut into other possible shapes, and the number and arrangement of the through holes 13 can also be adjusted.

[0026] This invention forms a regularly shaped elastomer channel by setting a vertical through hole 13 on the composite board 1 to obtain an elastomer ring 2, thereby achieving a fixed connection structure with the composite board 1.

[0027] Furthermore, the aforementioned external elastomer ring includes a first elastomer ring, a second elastomer ring, and a third elastomer ring. The first elastomer ring is disposed on the first surface, the second elastomer ring is disposed on the third surface of the composite plate 1, and the third elastomer ring is disposed on the second surface. The third surface is the surface adjacent to the first surface.

[0028] For example, the external elastic ring disposed on the outer surface of the composite board 1 may include a first elastic ring, a second elastic ring and a third elastic ring. The first elastic ring is disposed on the top surface of the composite board 1, i.e. the first surface, the second elastic ring is disposed on the side surface of the composite board 1, i.e. the third surface, and the third elastic ring is disposed on the bottom surface of the composite board 1, i.e. the second surface, so as to achieve a fixed connection between the external elastic ring and the top surface, side surface and bottom surface of the composite board 1.

[0029] This invention fixes the inner elastic ring and the outer elastic ring together, thereby achieving a fixed connection structure between the elastic ring 2 and the composite plate 1. This restrains the displacement and deformation of the composite plate 1 in the horizontal direction, improving its torsional resistance and tear resistance.

[0030] Furthermore, one end of the first elastic ring is fixedly connected to one end of the inner elastic ring, the other end of the first elastic ring is fixedly connected to one end of the second elastic ring, the other end of the second elastic ring is fixedly connected to one end of the third elastic ring, and the other end of the third elastic ring is fixedly connected to the other end of the inner elastic ring.

[0031] For example, one end of the first elastic ring disposed on the top surface of the composite board 1 is fixedly connected to one end of the inner elastic ring disposed inside the composite board 1, the other end of the first elastic ring is fixedly connected to one end of the second elastic ring disposed on the side of the composite board 1, the other end of the second elastic ring is fixedly connected to one end of the third elastic ring disposed on the bottom surface of the composite board 1, and the other end of the third elastic ring is fixedly connected to the other end of the inner elastic ring, so that the inner elastic ring and the outer elastic ring are connected in a closed loop, thereby realizing the fixed connection between the inner elastic ring and the outer elastic ring, and thus realizing the fixed connection between the composite board 1 and the elastic ring 2.

[0032] This invention achieves a fixed connection between the elastomer ring 2 and the composite plate 1 by fixing the inner elastomer ring and the outer elastomer ring together to obtain a closed annular elastomer ring 2.

[0033] Furthermore, the aperture of the aforementioned elastomer channel is the same as the aperture of the aforementioned first perforation; The diameters of the first elastomer ring, the second elastomer ring, and the third elastomer ring are all the same.

[0034] For example, the aperture of the elastomer channel is the same as the aperture of the first perforation, and the diameters of the first elastomer ring, the second elastomer ring, and the third elastomer ring are all the same, so that the shape of the elastomer ring 2 is a regular ring, ensuring that the elastomer ring 2 can be fixedly connected to the composite plate 1, and thus constraining the composite plate 1.

[0035] This invention achieves a fixed connection between the elastic ring 2 and the composite board 1 by setting an elastic ring 2 that penetrates through the composite board 1. Furthermore, the regular shape of the elastic ring 2 makes the overall structure more stable and controllable, so as to ensure that the elastic ring 2 can effectively constrain the multi-layer elastic board 11 and foam board 12 in the composite board 1.

[0036] Furthermore, the composite panel structure also includes a skin layer 3, which is fixedly disposed on the outer surface of the composite panel 1.

[0037] For example, the composite panel structure also includes a skin layer 3, which is an elastomer covering the surface of the composite panel 1. It can effectively ensure the integrity of the entire assembly and improve its wear resistance, scratch resistance and puncture resistance. When applied to shoe sole components, it can better adapt to various sports scenarios, such as road, outdoor and indoor.

[0038] This invention, by setting a skin layer 3 on the outer surface of the composite board 1, can ensure the integrity of the overall structure, protect the composite board 1, and improve its durability and practicality.

[0039] Furthermore, a first elastomer is disposed within the aforementioned elastomer ring 2, and a second elastomer is disposed within the aforementioned skin layer 3; The hardness of the first elastic body is greater than that of the second elastic body.

[0040] For example, the elastomer ring 2 is filled with a first elastomer, and the skin layer 3 is filled with a second elastomer. The hardness of the first elastomer is greater than that of the second elastomer. The elastomer ring 2 can restrain the composite board 1, while the skin layer 3 can ensure the integrity of the overall structure and improve practicality and durability.

[0041] By using a suitable elastomer for filling, this invention can obtain a composite plate 1 structure with an elastomer ring 2 and a skin layer 3, which effectively improves its tear resistance, torsion resistance and wear resistance.

[0042] Furthermore, the diameter of the first perforation is greater than 3 mm.

[0043] For example, in order to inject the first elastomer into the elastomer channel, the diameter of the first perforation can be set to be greater than 3 mm, preferably greater than or equal to 4 mm, to form an elastomer ring 2, thereby constraining the multilayer elastic plate 11 and foamed plate 12 in the composite board 1 and improving the tear resistance and torsional resistance of the composite board 1 structure.

[0044] This invention allows for adjustment of the size of the elastomer ring 2 by adjusting the diameter of the through hole 13, making the size of the elastomer ring 2 flexible and controllable, and enabling appropriate adjustments as needed, thereby achieving the constraint effect on the elastic plate 11 and the foamed plate 12 in the composite board 1.

[0045] Furthermore, the thickness of the elastic plate 11 is 0.2-0.5 mm, and the thickness of the foamed plate 12 is 2-5 mm.

[0046] For example, the elastic board 11 can be an ultra-thin elastic board 11 (including thermoplastic elastomer, engineering plastic, carbon fiber board, etc.), with a thickness range of 0.2-0.5 mm; the foam board 12 can be a multi-layer foam board with a thickness range of 2-5 mm.

[0047] For example, the number of alternating stacked layers of elastic board 11 and foam board 12 in composite board 1 is not limited in this invention. Furthermore, the top panel of composite board 1 can be either foam board 12 or elastic board 11, and the bottom panel can also be either foam board 12 or elastic board 11, which can be appropriately adjusted according to the requirements of performance such as resilience. In addition, the thickness of composite board 1 obtained after alternating stacking of elastic board 11 and foam board 12 is preferably less than or equal to 30 mm. The number of elastic boards 11 can be controlled to within eleven, and the number of foam boards 12 can be controlled to within ten. Here, less than or equal to 30 mm is only a preferred thickness for composite board 1; in actual use, composite boards with a thickness greater than 30 mm can be obtained according to actual needs.

[0048] This invention allows for flexible preparation by alternately layering elastic boards 11 and foam boards 12 of appropriate thickness. This effectively controls the overall thickness of the composite board 1 and ensures that it has good resilience and support.

[0049] This invention utilizes the flexibility of an ultra-thin elastic plate 11 (such as thermoplastic elastomer, engineering plastic, carbon fiber plate, etc.) to alternately stack with a multi-layer foamed plate 12, forming a composite plate component 1 of a certain thickness. Several channels are opened in the vertical direction, and the channels are filled with a first elastomer. In the horizontal direction, adjacent vertical channels are connected in pairs to form a closed elastomer ring 2, realizing a fixed connection structure between the composite plate 1 and the elastomer ring 2. Then, a layer of second elastomer with good airtightness and wear and scratch resistance is cast as a whole to form a skin layer 3, which wraps the entire assembly, thus obtaining the final composite plate 1 structure. When subjected to impact or compression in the vertical direction, the elastic plate 11 rapidly transfers the load to each layer of foam board 12. Upon rebound, it can also quickly release elastic potential energy, increasing rebound speed and force, and providing good resilience and support. When subjected to shear force in the horizontal direction, there may be a certain relative displacement between the elastic plate 11 and the foam board 12 in the horizontal direction. The elastomer ring 2 can act as a constraint at this time, effectively suppressing horizontal shear deformation. In addition, since the foam board 12 is a multi-layered structure, it can effectively reduce the probability of interlayer tearing of the foam board 12 and improve tear resistance. When bending or torsion occurs, the elastomer ring 2 between the multi-layered foam board 12 and the elastic plate 11 can act as a constraint, effectively improving torsional resistance, and making the torsional resistance of the composite board 1 structure much greater than that of the foam board 12 itself. The high-density second elastomer covering the surface can ensure the integrity of the overall structure, improve wear resistance, scratch resistance, and puncture resistance, making it more durable and adaptable to various different sports scenarios.

[0050] This utility model also provides a shoe midsole, which includes the composite plate structure described above.

[0051] This utility model also provides a shoe, which includes the midsole described above, has good resilience and support, and is tear-resistant, torsional-resistant, abrasion-resistant, scratch-resistant and puncture-resistant, and can adapt to a variety of different sports scenarios.
