Description

Technical Field

[0001] The present application relates to the field of shoe soles, and in particular to a carbon fiber plate structure and a shoe sole having the carbon fiber plate structure. Background Art

[0002] In the design of running shoe soles, elastic members are usually added to meet the requirement of shock absorption performance. In order to achieve the purpose of elastic shock absorption, the existing elastic members usually have a large elasticity, that is, they are more likely to undergo a large deformation during the impact of the wearer's foot with the ground; at the same time, due to insufficient rigidity, after the deformation occurs, the recovery speed is slow, resulting in a lack of boosting effect of the elastic members during the running process of the wearer.

[0003] If the rigidity of the elastic member is increased, although it is beneficial to improve the boosting effect by force feedback, it will increase the difficulty of the elastic member to deform, and thus increase the risk of foot injury to the wearer during running.

[0004] Therefore, a structure is needed that takes into account both the boosting effect of the running shoe sole and the protection of the wearer's foot by the running shoe. Summary of the Utility Model

[0005] In order to take into account both the boosting effect of the running shoe sole and the protection of the wearer's foot by the running shoe, the present application provides a carbon fiber plate structure and a shoe sole having the carbon fiber plate structure.

[0006] On the one hand, a carbon fiber plate structure provided by the present application adopts the following technical solution:

[0007] A carbon fiber plate structure includes a plate body, the plate body includes an upper connecting portion, a lower connecting portion and a curved surface connecting portion, the upper connecting portion and the lower connecting portion are arranged opposite to each other, and there is a deformation cavity between the upper connecting portion and the lower connecting portion; one side of the curved surface connecting portion is connected to the upper connecting portion, and the other side is connected to the lower connecting portion; the plate body includes at least two carbon fiber layers, and the weaving textures of adjacent carbon fiber layers are arranged alternately.

[0008] By adopting the above technical solution, when using the carbon fiber plate structure, the carbon fiber plate structure is placed in the sole. When the wearer runs, when the sole hits the ground, the force of the wearer's foot is transmitted to the upper connecting part, the upper connecting part moves in the direction close to the lower connecting part, and the curved surface connecting part is bent and deformed. Since there is a deformation cavity between the upper connecting part and the lower connecting part, and the upper connecting part and the lower connecting part are connected by the curved surface connecting part, the carbon fiber plate structure can be deformed more easily to protect the wearer's feet. At the same time, since the carbon fiber plate has a large rigidity and bending modulus, it is easier to reset after the upper connecting part moves, that is, it has a better boosting effect, so that the sole of the running shoe can take into account the boosting effect and the protective effect on the wearer's feet. The staggered arrangement of the texture between adjacent carbon fiber layers allows the stress to be dispersed in multiple directions, reducing the force concentration of the carbon fiber structure and reducing the risk of fracture at the curved surface connecting part.

[0009] Optionally, the staggered angle of the weaving textures of adjacent carbon fiber layers is between 10 and 20 degrees.

[0010] By adopting the above technical solution, while ensuring that the texture is staggered, the distribution density of the carbon fiber texture in the thickness direction of the plate is relatively large, so as to further improve the overall structural strength of the plate and reduce the risk of plate breakage.

[0011] Optionally, the concave surface of the curved connecting portion faces the deformation cavity.

[0012] By adopting the above technical solution, on the one hand, the connection transition between the upper connecting part and the curved connecting part, and between the lower connecting part and the curved connecting part is smoother, and the connection can be formed by one-piece molding, thereby improving the structural strength of the plate body; on the other hand, the curved connecting part is outside the deformation cavity, so as not to form a barrier between the upper connecting part and the lower connecting part, thereby ensuring the deformation stability of the plate body when subjected to force, and further ensuring the wearing comfort of the wearer.

[0013] Optionally, two curved surface connection parts are provided, the two curved surface connection parts are arranged opposite to each other, and the two curved surface connection parts are respectively provided at two ends of the upper connection part.

[0014] By adopting the above technical solution, the bending position between the upper connecting part and the lower connecting part is increased, stress dispersion is further formed, and the risk of the plate body breaking at the position of the curved surface connecting part is reduced.

[0015] Optionally, the concave surfaces of the two curved connecting parts both face the deformation cavity.

[0016] By adopting the above technical solution, on the one hand, both of the two curved surface connecting parts are outside the deformation cavity, reducing the influence on the moving distance of the upper connecting part relative to the lower connecting part, that is, reducing the influence on the elastic performance of the carbon fiber board structure; on the other hand, it is also convenient to connect the upper connecting part, the curved surface connecting part and the lower connecting part by integral molding, ensuring the structural strength of the carbon fiber board structure.

[0017] Optionally, the plate body further includes an extension part, the extension part is connected to the front end of the upper connecting part, and the extension part extends along the length direction of the shoe sole.

[0018] By adopting the above technical solution, an extension part extending along the length direction of the shoe sole is introduced. On the one hand, it increases the connection area between the plate body and the shoe sole, improving the connection stability after the carbon fiber board structure is arranged on the shoe sole; on the other hand, the extension part plays a certain supporting role on the shoe sole, that is, the carbon fiber board structure takes into account the supporting performance, shock absorption performance and boosting effect of the shoe sole at the same time.

[0019] Optionally, an elastic support member is arranged in the deformation cavity, the upper surface of the support member contacts the upper connecting part, and the lower surface of the support member contacts the lower connecting part.

[0020] By adopting the above technical solution, on the one hand, when the upper connecting part approaches the lower connecting part, the support member forms a certain support for the upper connecting part, reducing the risk of the plate body breaking at the position of the curved surface connecting part; on the other hand, the elastic support member is used to assist the reset of the upper connecting part, further improving the boosting effect of the carbon fiber board structure.

[0021] Optionally, the upper connecting part is bent, and the concave surface of the upper connecting part faces the deformation cavity.

[0022] By adopting the above technical solution, the upper connecting part is in an arch shape, further improving the structural strength of the carbon fiber board structure and reducing the risk of the carbon fiber board structure breaking.

[0023] Optionally, the lower connecting part is bent, and the concave surface of the lower connecting part faces the deformation cavity.

[0024] By adopting the above technical solution, the lower connecting part is in an inverted arch shape, further improving the structural strength of the carbon fiber board structure and reducing the risk of the carbon fiber board structure breaking.

[0025] On the other hand, a shoe sole with a carbon fiber board structure provided by the present application adopts the following technical solution:

[0026] A shoe sole with a carbon fiber board structure includes a shoe sole body, the shoe sole body has an installation cavity, and the above carbon fiber board structure is installed in the installation cavity.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The plate body includes an upper connecting portion, a lower connecting portion and a curved surface connecting portion. There is a deformation cavity between the upper connecting portion and the lower connecting portion, and the curved surface connecting portion is used to establish a connection between the upper connecting portion and the lower connecting portion, so that after the carbon fiber plate structure is arranged on the sole, the boosting effect of the running shoe sole and the protection of the running shoe on the wearer's foot can be taken into account; in addition, the plate body includes multiple carbon fiber layers, and the textures of adjacent carbon fiber layers are staggered to disperse stress when the plate body is stressed and reduce the risk of the plate body breaking;

[0029] 2. The upper connecting portion, the lower connecting portion and the curved surface connecting portion are all bent, and the concave surfaces of the three all face the deformation cavity, which improves the structural strength of the plate body and reduces the risk of the plate body breaking when stressed;

[0030] 3. A support member is arranged between the upper connecting portion and the lower connecting portion. The support member has elasticity, which can assist the upper connecting portion to reset while reducing the risk of the plate body breaking and further improve the boosting effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0039] The following will further elaborate on this application in conjunction with the attached Figures 1-7 drawings for a more detailed description.

[0040] An embodiment of this application discloses a carbon fiber board structure and a sole having such a carbon fiber board structure.

[0041] Embodiment 1

[0042] This embodiment discloses a carbon fiber board structure.

[0043] Referring to Figure 1 , a carbon fiber board structure includes a board body 1. The board body 1 includes an upper connecting portion 2, a lower connecting portion 3, and a curved connecting portion 4. The upper connecting portion 2 and the lower connecting portion 3 are disposed opposite to each other, and there is a deformation cavity 11 between the upper connecting portion 2 and the lower connecting portion 3. One side of the curved connecting portion 4 is connected to the upper connecting portion 2, and the other side is connected to the lower connecting portion 3.

[0044] Referring to Figure 2 , the board body 1 includes at least two layers of carbon fiber layers 5, and the weaving textures of adjacent carbon fiber layers 5 are staggered. Through the above design, when using the carbon fiber board structure, the carbon fiber board structure is placed in the sole. During the running process of the wearer, when the sole hits the ground, the force of the wearer's foot is transmitted to the upper connecting portion 2, the upper connecting portion 2 moves towards the direction close to the lower connecting portion 3, and the curved connecting portion 4 undergoes a bending deformation. Since there is a deformation cavity 11 between the upper connecting portion 2 and the lower connecting portion 3, and the upper connecting portion 2 and the lower connecting portion 3 are connected by the curved connecting portion 4, the carbon fiber board structure can be deformed relatively easily to protect the wearer's foot. At the same time, because the carbon fiber board has a large rigidity and bending modulus, it is easier to reset after the upper connecting portion 2 moves, that is, it has a better boosting effect, so that the sole of the running shoe can take into account both the boosting effect and the protection of the wearer's foot. And the staggered arrangement of the textures between adjacent carbon fiber layers 5 enables multi-directional stress dispersion, reduces the stress concentration degree of the carbon fiber structure, and reduces the risk of fracture at the curved connecting portion 4.

[0045] In this embodiment, the upper connecting portion 2, the lower connecting portion 3, and the curved connecting portion 4 are integrally formed. When manufacturing the board body 1, first make a mold according to the required shape, and then sequentially laminate multiple layers of carbon fiber layers 5 on the mold for shaping, so as to realize the integral forming of the upper connecting portion 2, the lower connecting portion 3, and the curved connecting portion 4, thereby ensuring the structural strength of the board body 1 and reducing the risk of fracture of the board body 1 after being stressed.

[0046] In this embodiment, the staggered angle between the weaving textures of adjacent carbon fiber layers 5 is between 10 - 20 degrees, preferably 15 degrees. In other embodiments, the staggered angle can also be other degrees.

[0047] Return toFigure 1 In this embodiment, the concave surface of the curved connecting portion 4 faces the deformation cavity 11. On the one hand, this makes the connection transition between the upper connecting portion 2 and the curved connecting portion 4, and between the lower connecting portion 3 and the curved connecting portion 4 relatively smooth, and the connection can be formed by an integral molding method, improving the structural strength of the plate body 1; on the other hand, it makes the curved connecting portion 4 outside the deformation cavity 11, so as not to form an obstruction between the upper connecting portion 2 and the lower connecting portion 3, ensuring the deformation stability of the plate body 1 when stressed, and thus ensuring the wearing comfort of the wearer.

[0048] One side of the curved connecting portion 4 is connected to the front end of the upper connecting portion 2, and the other side is connected to the front end of the lower connecting portion 3. That is, when the carbon fiber plate structure is installed in the sole, the curved connecting portion 4 is located at a position close to the arch of the foot. Thereby, the curved connecting portion 4 forms a better support for the position of the foot close to the arch, and also makes the position of the sole closer to the rear more likely to deform and easier to reset, further improving the elastic performance and boosting effect of the sole.

[0049] In this embodiment, the upper connecting portion 2 is bent, and the concave surface of the upper connecting portion 2 faces the deformation cavity 11. That is, the upper connecting portion 2 is in an arched shape, making the plate body 1 have a high structural strength and reducing the risk of the plate body 1 breaking at the curved connecting portion.

[0050] In this embodiment, the lower connecting portion 3 is bent, and the concave surface of the lower connecting portion 3 faces the deformation cavity 11. That is, the lower connecting portion 3 is in an inverted arched shape, making the plate body 1 have a high structural strength and reducing the risk of the plate body 1 breaking during bending.

[0051] In this embodiment, an elastic support member 6 is provided in the deformation cavity 11. The upper surface of the support member 6 contacts the upper connecting portion 2, and the lower surface of the support member 6 contacts the lower connecting portion 3. With this design, on the one hand, during the process of the upper connecting portion 2 approaching the lower connecting portion 3, the support member 6 forms a certain support for the upper connecting portion 2, reducing the risk of the plate body 1 breaking at the position of the curved connecting portion 4; on the other hand, the elastic support member 6 is used to assist the reset of the upper connecting portion 2, further improving the boosting effect of the carbon fiber plate structure.

[0052] The implementation principle of Embodiment 1 is: When producing the carbon fiber plate structure, first make a mold according to the shape of the required carbon fiber plate, and then sequentially laminate multiple carbon fiber layers 5 on the mold to be shaped into the shape of the required carbon fiber plate.

[0053] When using the carbon fiber plate structure, place the carbon fiber plate structure in the sole. During the wearer's running, the sole hits the ground, and the upper connecting part 2 moves towards the lower connecting part 3, playing a certain shock-absorbing role. Then, under the action of the curved surface connecting part 4, the upper connecting part 2 quickly resets, enabling the running shoes provided with the carbon fiber plate structure to balance the boosting effect of the running shoe sole and the protection of the wearer's feet.

[0054] Embodiment 2

[0055] Referring to Fig. 3, the difference between this embodiment and Embodiment 1 is that there are two curved surface connecting parts 4, and the two curved surface connecting parts 4 are arranged oppositely. Thus, the bending position between the upper connecting part 2 and the lower connecting part 3 is increased, further forming stress dispersion and reducing the risk of the plate body 1 breaking at the position of the curved surface connecting part 4.

[0056] In this embodiment, the concave surfaces of the two curved surface connecting parts 4 both face the deformation cavity 11. With this design, on the one hand, it makes both curved surface connecting parts 4 outside the deformation cavity 11, reducing the influence on the moving distance of the upper connecting part 2 relative to the lower connecting part 3, that is, reducing the influence on the elastic performance of the carbon fiber plate structure; on the other hand, it is also convenient to connect the upper connecting part 2, the curved surface connecting part 4 and the lower connecting part 3 by integral molding, ensuring the structural strength of the carbon fiber plate structure.

[0057] In other embodiments, it can also be that the convex surfaces of the two curved surface connecting parts 4 face the deformation cavity 11, or the convex surface of one of the curved surface connecting parts 4 faces the deformation cavity 11.

[0058] Embodiment 3

[0059] Referring to Figure 4 , the difference between this embodiment and Embodiment 1 is that the plate body 1 further includes an extension part 7, and the extension part 7 is connected to the front end of the upper connecting part 2. With this design, on the one hand, it increases the connection area between the plate body 1 and the sole, improving the connection stability after the carbon fiber plate structure is arranged in the sole; on the other hand, the extension part 7 plays a certain supporting role on the sole, that is, the carbon fiber plate structure takes into account the supporting performance, shock-absorbing performance and boosting effect of the sole at the same time.

[0060] Embodiment 4

[0061] Referring to Figure 5 , this embodiment provides a sole with the above-mentioned carbon fiber plate structure 9, including a sole body 8, and the sole body 8 has an installation cavity 81, and the above-mentioned carbon fiber plate structure 9 is installed in the installation cavity 81.

[0062] When the carbon fiber plate structure is the carbon fiber plate structure 9 described in Embodiment 1, the curved surface connecting part 4 is located on one side of the upper connecting part 2 near the arch position of the sole.

[0063] Refer to Figure 6 , when the carbon fiber plate structure is the carbon fiber plate structure 9 described in Embodiment 2, the installation cavity 81 is arranged at the position of the rear sole of the sole body 8.

[0064] Refer to Figure 7 , when the carbon fiber plate structure is the carbon fiber plate structure 9 described in Embodiment 3, the curved surface connecting portion 4 is connected to the rear end of the upper connecting portion 2, and the end portion of the extending portion 7 away from the upper connecting portion 2 extends to the position of the front sole of the sole body 8.

[0065] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
