DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be apparently and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0026] Embodiment: please refer to Figures 1 to 4 According to the embodiments of the present application, a technical solution is provided: a shoe midsole with carbon fiber piece reinforced structure, comprising: a shoe midsole body 1, which comprises a forefoot tread area 101, a heel tread area 102 and a midfoot area 103, the surfaces of the forefoot tread area 101 and the heel tread area 102 are adhered with silica gel gaskets 2; a carbon fiber piece structure, which comprises an outer contour piece 3 and an inner support piece 4, the outer contour piece 3 is clamped in the shoe midsole body 1 and is arranged along the contour periphery of the shoe midsole body 1, the shape of the inner support piece 4 is an equal proportion reduction of the outer contour piece 3 and is clamped in the shoe midsole body 1, and the inner support piece 4 is located in the middle of the outer contour piece 3.

[0027] It should be noted that the shoe midsole body 1 can be made of double or triple layer materials. The common double layer material can be made of EVA or similar materials with different densities to make the middle layer and the lower layer, and the upper layer is made of silica gel to increase comfort. The upper layer of the triple layer material is made of PORON foam. Through its excellent energy absorption characteristics, it can absorb the impact force when the foot lands, increase comfort, the middle layer is made of EVA or Boost to provide cushioning and rebound effect, and the bottom layer is made of thermoplastic polyurethane elastomer rubber (TPU) plate to enhance the anti-torsion and stability of the midsole, ensuring the safety and comfort of the foot during complex movements.

[0028] The shoe midsole with carbon fiber sheet reinforcing structure has the advantages that the silica gel pad 2 is adhered to the surface of the forefoot tread area 101 and the heel tread area 102, the silica gel pad 2 is soft and has good elasticity and adhesion, can enhance the friction between the two main stress areas and the sole, effectively prevent the insole from sliding, and improve the stability of wearing; secondly, it can play a buffering role, reduce the impact force between the foot and the midsole, and improve the comfort; and when the foot is stressed, the inner circle support sheet 4 and the outer circle contour sheet 3 can be depressed, so that the comfort and fitness are not affected by the flexibility of the traditional carbon fiber sheet, and the comfort of wearing is effectively improved. Moreover, the inner circle support sheet 4 and the outer circle contour sheet 3 are used in cooperation, which not only ensures the reinforcing effect, but also greatly reduces the amount of carbon fiber compared with using a whole piece of carbon fiber material, thereby reducing the cost.

[0029] The upper surface of the shoe midsole body 1 is adhered to the linen layer 5, and the linen layer 5 is covered on the silica gel pad 2. The linen has good air permeability, can keep the feet dry, reduce the stuffy feeling and discomfort caused by sweating of the feet, and improve the overall wearing comfort; secondly, the linen layer 5 can protect the silica gel pad 2 below, avoid the silica gel pad 2 from being directly contacted with the feet or the insole to be worn or contaminated, and prolong the service life of the silica gel pad 2; thirdly, the surface texture of the linen layer 5 is relatively rough, which can further increase the friction between the insole and the silica gel pad 2 to better prevent the insole from moving.

[0030] The carbon fiber connecting sheet 6 is arranged between the outer circle contour sheet 3 and the inner circle support sheet 4, and the two sides of the carbon fiber connecting sheet 6 are fixed with the outer circle contour sheet 3 and the inner circle support sheet 4 respectively. Through the carbon fiber connecting sheet 6, the carbon fiber sheet structure is better placed in the shoe midsole body 1 during production for molding, and the assembly is more convenient, and the positioning difficulty is reduced.

[0031] The middle part of the foot 103 is adapted to form a raised block 7 upwardly at the part of the foot arch, which is adapted to the foot arch, and can provide strong support for the foot arch, effectively disperse the foot pressure, reduce the burden of the foot arch, prevent the foot arch fatigue and injury caused by long time walking or exercise. At the same time, the good fit with the foot arch also enhances the overall wrap and fit of the shoe, improves the comfort and stability of wearing.

[0032] The bottom of the foot 101 is fixedly installed with a uniform array of wave bonding protrusions 8, and the wave bonding protrusions 8 between two adjacent wave bonding protrusions 8 can be filled with adhesive. The wave bonding protrusions 8 increase the contact area between the midsole and the sole, and further enhance the friction through the unique wave shape of the wave bonding protrusions 8. The wave bonding protrusions 8 between two adjacent wave bonding protrusions 8 can be filled with adhesive, which further strengthens the connection between the midsole and the sole, effectively prevents the midsole from shifting or falling off during use, and greatly improves the overall durability and reliability of the shoe.

[0033] The heel of the shoe 102 is fixedly installed with a TPU plate 9 at the bottom of the shoe midsole body 1, and the TPU plate 9 is filled with a polyurethane layer 10 between the shoe midsole body 1. The TPU plate 9 has high strength, high toughness, good wear resistance and impact resistance, etc., which can provide strong support and stable protection for the heel.

[0034] During walking or exercise, the TPU plate 9 can effectively resist the reaction force from the ground, reduce the impact force on the heel, and reduce the risk of injury. At the same time, the TPU plate 9 can also enhance the structural strength of the shoe midsole at the heel part, preventing deformation or damage due to long-term use.

[0035] The PU plate and the shoe midsole body 1 are filled with a polyurethane layer 10, and the polyurethane material has excellent cushioning performance and resilience, which can play a good transition and buffering effect between the TPU plate and the shoe midsole body 1.

[0036] When the heel is in contact with the ground, the polyurethane layer 10 can further absorb and disperse the impact force, making the foot feel softer and more comfortable support, and improving the overall shock absorption effect. In addition, the polyurethane layer 10 also has certain viscosity, which can enhance the connection stability between the TPU plate and the shoe midsole body 1, and ensure that they do not relatively displace during use.

[0037] The edge of the shoe midsole body 1 is fixedly installed with a rough layer 11 on the part embedded in the sole, which increases the friction between the midsole and the sole. After being embedded in the sole with adhesive, the midsole can be more firmly embedded in the sole.

[0038] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
