[0002] Shoes are one of the most commonly used items in people's daily life, which can effectively protect the human foot and improve the experience of walking and running. The existing shoes are usually composed of sole, upper and other structures. Some of these shoes will embed or bond reinforcing structures such as carbon fiber plates on the bottom or upper surface of the sole to enhance structural strength and improve elasticity. However, the existing surface bonding method is not firm and can easily cause the reinforcing structure to delaminate and peel off from the main body of the shoe. SUMMARY

[0004] A 3D printing shoe with a carbon fiber reinforcing plate includes a sole and a first carbon fiber plate. The sole is 3D printed in one piece, and the sole further includes a bottom layer, a middle layer, and an inner layer stacked in order from bottom to top. The first carbon fiber plate is integrally embedded in the middle layer.

[0005] Further, a plurality of reinforcing holes are provided on the first carbon fiber plate, and the middle layer is filled in the reinforcing holes.

[0006] Further, the middle layer is designed in a grid open structure, which includes a plurality of interconnected grid edges, and the end portions of adjacent grid edges are connected to form nodes. Some of the grid edges are provided in the reinforcing holes.

[0007] Further, the top surface of the inner layer is further provided with a support surface, and a plurality of air holes are provided on the support surface.

[0008] Further, a second carbon fiber plate is further included, which is arranged on the bottom surface of the bottom layer.

[0009] Further, the bottom layer of the sole is further provided with a first edge wrapping structure, and the first edge wrapping structure extends on the outer peripheral edge of the bottom surface of the second carbon fiber plate.

[0010] Further, a third carbon fiber plate is further included, which is arranged on the top surface of the inner layer.

[0011] Further, the top surface of the inner layer is further provided with a second edge wrapping structure, and the second edge wrapping structure extends on the outer peripheral edge of the top surface of the third carbon fiber plate.

[0012] Furthermore, a stepped surface is provided on the outer periphery of the second carbon fiber plate, and the first edging structure extends to the bottom surface of the stepped surface of the second carbon fiber plate.

[0013] Furthermore, the sole is made of flexible plastic or resin material.

[0014] In summary, the beneficial effects of this utility model of a 3D-printed shoe with carbon fiber reinforcement are as follows: By designing a 3D-printed one-piece shoe, the production process can be simplified, thereby improving production efficiency. It also allows for the creation of complex structures such as hollow designs and integrated carbon fiber reinforcement. Furthermore, the carbon fiber reinforcement embedded within the sole ensures that it will not separate from the shoe body, significantly extending the shoe's lifespan. The multi-layered or bonded carbon fiber reinforcement design within the shoe greatly enhances its elasticity and overall structural strength. The hollow design of the shoe body reduces weight and improves breathability, thus significantly enhancing the user experience. This utility model is highly practical and has significant potential for widespread adoption. Attached Figure Description
