Description

Technical Field

[0001] The present application relates to the technical field of shoe soles, and particularly to a comfortable shoe sole with non-Newtonian fluid. Background Art

[0002] With the continuous development of sports science and materials science, the comfort, shock absorption and functionality of footwear products have become important indicators that consumers increasingly concern. In footwear products, as the part directly contacting the ground, the shock absorption performance and stability of the shoe sole are crucial for the foot health of users. Traditional shoe sole materials such as EVA, although having a certain shock absorption effect, often have difficulty maintaining sufficient stability and support under high impact forces, and are prone to causing damage to the knees and ankles of users.

[0003] Content of the Application

[0004] The purpose of the embodiments of the present application is to provide a comfortable shoe sole with non-Newtonian fluid, so as to solve the technical problem that the shoe sole in the prior art often has difficulty maintaining sufficient stability and support under high impact forces.

[0005] To achieve the above purpose, the technical solution adopted by the present application is: to provide a comfortable shoe sole with non-Newtonian fluid, including a shoe sole body made of EVA material; the shoe sole body includes a heel area, an arch area and a front area; the shoe sole body has a shoe bottom surface contacting the outside and a shoe inner surface supporting the human foot; a carbon fiber board and non-Newtonian fluid blocks are arranged on the shoe inner surface.

[0006] Through the above technical solution, non-Newtonian fluid, as a material with unique dynamic mechanical properties, can exhibit the transformation characteristics from fluid to elastomer or rigid solid under different impact speeds and energy conditions. Especially in the design of shoe soles, non-Newtonian fluid materials can provide different mechanical feedbacks under different motion states due to their unique strain rate response characteristics. For example, when walking, the shoe sole can exhibit soft and comfortable characteristics; while when running or jumping, the shoe sole can quickly harden to provide sufficient support and shock absorption effects; and the setting of the carbon fiber board can improve the support force and the strength of the shoe sole, and moreover, the carbon fiber board is light in weight and will not increase the weight of the shoe sole.

[0007] Optionally, a strip-shaped through hole is arranged on the arch area, penetrating the shoe bottom surface and the shoe inner surface; a strip-shaped groove is arranged on the shoe inner surface; the strip-shaped through hole is located in the strip-shaped groove; the carbon fiber board is arranged in the strip-shaped groove and has the same shape as the strip-shaped groove.

[0008] Through the above technical solution, the strip-shaped through hole plays a role in weight reduction. The carbon fiber board is arranged in the middle of the shoe sole, that is, at the position of the arch area, to achieve the support of the sole and strengthen the strength of the shoe sole.

[0009] Optionally, a number of transverse grooves are provided in the front end area; a water droplet-shaped rear through hole is provided on the heel area, penetrating the bottom surface and the inner surface of the shoe; a circular accommodation groove is provided on the inner surface of the shoe; the rear through hole is provided at the bottom of the accommodation groove; the non-Newtonian fluid block is provided in the accommodation groove, and the shape of the non-Newtonian fluid block is set to be cylindrical, which is consistent with the shape of the accommodation groove.

[0010] Through the above technical solution, the setting of the rear through hole can achieve the effect of weight reduction. The setting of the accommodation groove can be used to place the non-Newtonian fluid block.

[0012] Through the above technical solution, the rear groove is used for gluing with the rear transparent plate. While reducing the weight of the rear through hole, it can prevent impurities from entering and polluting the sole.

[0013] Optionally, a strip-shaped middle groove is provided on the bottom surface of the arch area; the strip-shaped through hole is provided at the bottom of the middle groove; the strip-shaped through hole, the middle groove, and the strip-shaped groove communicate with each other; a middle transparent plate is provided in the middle groove; the side surface of the middle transparent plate facing away from the middle groove is set to be an arc surface.

[0014] Through the above technical solution, the strip-shaped through hole also plays a role in weight reduction. When the middle transparent plate is glued to the middle groove, it can prevent impurities from entering and polluting the sole. The setting of the arc surfaces of the rear transparent plate and the middle transparent plate has an aesthetic effect.

[0015] Optionally, the bottom surface of the shoe is set to be boat-shaped; anti-slip patterns are provided on the bottom surface of the shoe; the anti-slip patterns include needle-shaped depressions provided in the middle; the middle transparent plate and the rear transparent plate are provided in the needle-shaped depressions; the anti-slip patterns on both sides of the needle-shaped depressions further include a number of mutually connected or independently provided transverse anti-slip grooves and vertical anti-slip grooves.

[0016] Through the above technical solution, the setting of the anti-slip patterns can play an anti-slip role. Among them, the transverse anti-slip grooves and the vertical anti-slip grooves can play an anti-slip role in the transverse or vertical direction. The number of transverse anti-slip grooves in the front end area is greater than the number of vertical anti-slip grooves, while the number of transverse anti-slip grooves in the arch area and the heel area is less than the number of vertical anti-slip grooves.

[0017] Optionally, a number of anti-slip notches are provided at the edge of the bottom surface of the front end area.

[0018] Advantages of this application: Compared with the prior art, the comfortable sole with non-Newtonian fluid provided by this application has the advantages of light weight, high strength, elasticity, and can maintain sufficient stability and support under the action of high impact force.
