Description

Technical Field

[0001] The utility model relates to the field of shoes, in particular to a carbon plate for shoes and a shoe sole having the same. Background Art

[0002] In the shoe sole, by increasing the structure of the carbon plate, the performance of the support and elasticity of the shoe sole is significantly improved. It not only improves the shoe sole performance, but also provides protection for the human foot. However, the traditional carbon plate is in an overall planar shape. If the weight needs to be reduced, its rigidity and strength are likely to be sacrificed. For example, the purpose of reducing weight is achieved by reducing the stacking layers of carbon fiber sheets; or, high-strength carbon fiber is used to achieve high strength and low gram weight, but the high-strength carbon fiber is expensive and the production cost is high. Therefore, it is difficult to balance the strength, weight and economy of the carbon plate. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a carbon plate for shoes and a shoe sole having the same, aiming to improve the problem of relatively single functionality of the existing carbon plate.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions: A carbon plate for shoes, comprising:

[0005] The forefoot part, on which a net-shaped first hollow part is arranged;

[0006] The rearfoot part, at the heel of which a partition opening extending towards the forefoot part is arranged, and a second hollow part is arranged on the rearfoot part; and

[0007] The arch part, which is connected between the forefoot part and the rearfoot part, and at least a pair of hollow holes are arranged on both sides of the arch part.

[0008] Preferably, the toe area of the forefoot part is flat, and the forefoot part is an arc-shaped plate with the toe area warped.

[0009] Preferably, the first hollow part includes a plurality of outer hollow holes corresponding to the outer side of the foot and arranged along the outer side edge, a plurality of inner hollow holes corresponding to the inner side of the foot and arranged along the inner side edge, and a plurality of middle hollow holes arranged in a row in the middle of the forefoot part, and the plurality of middle hollow holes are arranged in a row connected with the partition opening.

[0010] Preferably, the rearfoot part and the arch part have the same width.

[0011] Preferably, the hollow holes are long strip holes, a pair of the long strip holes are symmetrically arranged on the arch part, and a connecting block is arranged between the pair of long strip holes.

[0012] Preferably, the bending stiffness of the forefoot part, the rearfoot part and the arch part is 700 - 900 N, and the hardness is 80 - 98 D.

[0013] There is also provided a shoe sole with a carbon plate for shoes, including the carbon plate for shoes as described above.

[0014] Preferably, the carbon plate for shoes is provided with a multi-layer structure formed by molding at least two layers of carbon fiber cloth.

[0015] After adopting the above technical solution, compared with the background technology, the present utility model has the following advantages:

[0016] 1. Through the design of the first hollow part, the second hollow part and the hollow holes on the entire carbon plate for shoes, weight reduction is maximized. At the same time, the net-shaped first hollow part can correspond to the force exerted by the human foot, retaining sufficient structural strength; when the forefoot part is stressed, force conduction can also be carried out through the net-shaped structure to form a dispersion effect on the stress, thereby improving the support strength of the forefoot part, that is, the carbon plate for shoes has the characteristics of good structural strength and high stability, and has good practicability.

[0017] 2. The carbon plate for shoes is made by molding multiple layers of carbon fiber cloth, which improves the structural strength of the carbon plate for shoes, and further improves the structural performance of the carbon plate for shoes to ensure the strength of the hollow structure.

[0018] 3. The rearfoot part of the carbon plate for shoes is designed with a dividing opening, so that the rearfoot part is divided into two parts. In this way, when the rearfoot is stressed, the carbon plate feedback forces obtained at different positions are different. The inner side or the outer side is supported and feedback by the carbon plate of the rearfoot part on a single side, and the middle part can be feedback by the carbon plate of the entire rearfoot part, improving the flexibility and practicability of use.

[0030] Embodiment 1

[0031] Please refer to Figure 1 and Figure 2 As shown, this embodiment provides a carbon plate for shoes, which includes a forefoot part 10, a rearfoot part 20 and an arch part 30. A net-shaped first hollow part 101 is provided on the forefoot part 10; a partition opening 201 extending towards the forefoot part 10 is provided at the heel of the rearfoot part 20, and a second hollow part 202 is provided on the rearfoot part 20; the arch part 30 is connected between the forefoot part 10 and the rearfoot part 20, and at least a pair of hollow holes 301 are provided on both sides of the arch part 30. The entire carbon plate for shoes can be made and formed by using double-layer or more carbon fiber cloth to improve the structural strength of the carbon plate for shoes.

[0032] Specifically, through the design of the first hollow part 101, the second hollow part 202 and the hollow holes 301 on the entire shoe carbon plate, a net-like shoe carbon plate structure is formed, which can achieve weight reduction to a large extent. At the same time, the net-like first hollow part 101 can correspond to the force exerted by the human foot, retaining sufficient structural strength; when the front sole part 10 is stressed, force conduction can also be carried out through the net-like structure to form a force dispersion effect, thereby improving the support strength of the front sole part 10, that is, making the shoe carbon plate have good structural strength and high stability, and having good practicability.

[0033] Furthermore, through the design of the partition opening 201 in the rear sole part 20 of the shoe carbon plate, the rear sole part 20 is divided into two parts along the partition line from the front toe to the rear heel, and the partition opening 201 is a long strip-shaped through hole opening towards the rear heel direction, so that the rear sole part 20 is divided into two parts. When the rear sole is stressed, the carbon plate feedback forces obtained at different positions are different. Both the inner side and the outer side are supported and feedback through the carbon plate of the rear sole part 20 on a single side, and the middle part can be feedback by the carbon plate of the entire rear sole part 20, improving the flexibility and practicability of use.

[0034] At the arch part 30 position, a pair of hollow holes 301 are arranged on both sides of the arch, thereby achieving the effect of force divergence. That is, the middle waist width of the shoe carbon plate remains unchanged to provide support, and it also has the effect of enhancing the shock absorption force. Combined with the heel position, the structure from the arch to the heel position is divided into two parts. The design of the second hollow part 202 enables obvious feedback force to be provided to the human body when the heel / rear heel is laterally stressed, having good practicability.

[0035] Furthermore, in this embodiment, the flexural rigidity of the front sole part 10, the rear sole part 20 and the arch part 30 is 700 - 900 N, and the hardness is 80 - 98 D. Preferably, the flexural rigidity is 800 N, and the hardness is 92 D. With the hollow design, the carbon plate can have good structural strength and elastic properties, and can also achieve the effect of reducing the weight of the carbon plate by at least 35% (compared with the full carbon plate).

[0036] As Figure 2 shown, in this embodiment, the toe area of the front sole part 10 is a plane 102, and the front sole part 10 is an arc-shaped plate 103 with the toe area warped. The plane 102 design at the toe position can ensure the structural strength of the front end of the front sole part 10, that is, avoid the tip of the hollow structure from breaking. At the same time, the structural design of the arc-shaped plate 103 can make the front sole part 10 of the shoe carbon plate have good elastic properties to meet human actions such as pedaling.

[0037] Refer to Figure 1As shown, in this embodiment, the first hollow portion 101 includes a plurality of outer hollow holes 1011 corresponding to the outer side of the foot and arranged along the outer side, a plurality of inner hollow holes 1012 corresponding to the inner side of the foot and arranged along the inner side, and a plurality of middle hollow holes 1013 arranged in a row in the middle of the forefoot portion 10. The plurality of middle hollow holes 1013 and the partition opening 201 are arranged in rows.

[0038] Specifically, there are four inner hollow holes 1012 on the inner side and three outer hollow holes 1011, which respectively correspond to the stress areas on the sole during movement. The areas to be stressed are designed as hollow holes, thus forming a mesh structure. In this way, during movement, when the mesh structure is stressed, the force can be dispersed along the mesh structure, reducing the impact force generated during movement and achieving a shock absorption effect.

[0039] As Figure 1 shown, in this embodiment, the width of the rear foot portion 20 and the arch portion 30 is the same, so that the arch portion 30 and the rear foot portion 20 form a long strip structure. Through the design of the open rear foot portion 20, the rear foot portion 20 is easier to bend relative to the arch portion 30, providing good elasticity. The forefoot portion 10 can provide elastic force through the arc plate 103 to ensure the elastic force of the shoe carbon plate.

[0040] As Figure 1 shown, in this embodiment, the hollow hole 301 is a long strip hole, and a pair of long strip holes are symmetrically arranged on the arch portion 30, and a connecting block 302 is arranged between the pair of long strip holes. That is, the two sides of the arch portion 30 are designed through a pair of long strip holes, so that after exerting force, the force can be dispersed through the long strip holes, and combined with the design of the connecting block 302 to provide the required support, which can further enhance the shock absorption force and improve the practicability.

[0041] Embodiment 2

[0042] In this embodiment, a sole with a shoe carbon plate includes the shoe carbon plate described in Embodiment 1. Through the mesh hollow design of the shoe carbon plate, the weight of the carbon plate can be greatly reduced, and at the same time, the positive impact force can be dispersed to achieve a shock absorption effect.

[0043] In this embodiment, the shoe carbon plate is provided with a multi-layer structure formed by at least double-layer carbon fiber cloth by molding. The bending stiffness of the shoe carbon plate is 700 - 900 N, and the hardness is 80 - 98 D. By combining the mesh hollow and double-layer molding processes, the strength, stability, and load-bearing capacity of the shoe carbon plate are improved, while the weight is reduced, having good economic benefits.

[0044] As mentioned above, it is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
