[0003] At present, the rebound performance of 3D printed footwear products on the market still needs to be improved. Traditional footwear manufacturing processes usually use foam materials as soles to provide good cushioning performance. However, due to material and process limitations, the rebound performance and shock absorption performance of 3D printed footwear products are relatively average. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a 3D printed high resilience structure shoe for the above-mentioned existing technical problems, so as to solve the problems of poor rebound performance and shock absorption performance of 3D printed shoes in the prior art.
[0005] In view of this, the utility model provides a 3D printed high resilience structure shoe, including: a shoe body and a sole, characterized in that the sole includes: an upper sole and a lower sole, the upper sole and the lower sole are connected by front and rear endpoints, upper elastic layers and lower elastic layers are respectively arranged on the inner sides of the upper sole and the lower sole, a rectangular space is formed between the upper elastic layer and the lower elastic layer, a hollow structure formed by continuous arrangement of lattices is arranged in the rectangular space, and a shock absorption strengthening structure is also arranged in the rectangular space, and the shock absorption strengthening structure is arranged outside the hollow structure.
[0006] In this technical solution, by arranging an upper elastic layer and a lower elastic layer in the sole, as well as the hollow structure and the shock absorption strengthening structure in the rectangular space, the rebound performance and shock absorption performance of the sole can be effectively improved, so that the wearer can obtain better comfort and support when walking or exercising. The shoe body and the sole are integrally formed by 3D printing, reducing the material usage and the weight of the shoes, thereby improving the comfort of the wearer. And a hollow structure formed by continuous arrangement of lattices is arranged in the rectangular space. The lattice structure can effectively absorb the impact force and disperse the energy to the whole structure through its unique geometric structure, thereby reducing the local stress and providing a better shock absorption effect.
[0007] In the above technical solution, further, the rectangular space is one of a square, a rectangle, and a rhombus.
[0008] In this technical solution, these different geometric shapes provide diverse choices for the sole design.

[0010] In the above technical solution, further, the first reinforcing rib and the second reinforcing rib are arranged in a wavy line, and the protruding ends of the first reinforcing rib and the second reinforcing rib are fixedly connected to the upper elastic layer and the lower elastic layer.
[0011] In this technical solution, a stable grid structure is formed by the crossed first and second reinforcing ribs. This structure can effectively disperse the pressure from different directions and provide a more comprehensive shock-absorbing effect. The wave-shaped reinforcing ribs can produce a better elastic response when impacted, similar to the effect of a spring, which helps to absorb the impact force and rebound quickly. The design of the crossed reinforcing ribs increases the stability of the overall structure, especially when subjected to complex or multi-directional forces, which helps to improve the torsion resistance of the sole, thereby protecting the wearer's feet from injury.
[0012] In the above technical solution, further, the first reinforcing rib and the second reinforcing rib are made of polyimide material.
[0013] In the above technical solution, further, the upper surface of the upper base is provided with a plurality of air holes.

[0028] Embodiment 1:
[0029] By Figures 1-3As shown, the present embodiment provides a 3D printed high-resilience structural shoe comprising: a shoe body 1 and a sole 2, characterized in that the sole 2 comprises: an upper sole 3 and a lower sole 4, the upper sole 3 and the lower sole 4 are connected by front and rear end points 6, the inner sides of the upper sole 3 and the lower sole 4 are respectively provided with an upper elastic layer 9 and a lower elastic layer 10, a rectangular space 8 is formed between the upper elastic layer 9 and the lower elastic layer 10, a hollow structure 12 formed by continuously arranged lattices 11 is provided in the rectangular space 8, and a shock-absorbing reinforcement structure is also provided in the rectangular space 8, and the shock-absorbing reinforcement structure is arranged on the outside of the hollow structure 12. By arranging an upper elastic layer 9 and a lower elastic layer 10 in the sole 2, as well as a hollow structure 12 and a shock-absorbing reinforcement structure in the rectangular space 8, the rebound performance and shock-absorbing performance of the sole 2 can be effectively improved, so that the wearer can obtain better comfort and support when walking or exercising. The shoe body 1 and the sole 2 are integrally formed by 3D printing, which reduces the amount of material used and reduces the weight of the shoe, thereby improving the comfort of the wearer. In addition, a hollow structure 12 formed by continuously arranged lattices 11 is provided in the rectangular space 8. The lattice 11 structure can effectively absorb impact force and disperse energy to the entire structure through its unique geometric structure, thereby reducing local force and providing better shock-absorbing effect.
[0030] Furthermore, the rectangular space 8 is one of a square, a rectangle, and a rhombus. These different geometric shapes provide diverse options for the design of the sole 2.
[0031] Furthermore, the shock-absorbing reinforcement structure is formed by crossing a plurality of first reinforcement ribs 13 and a plurality of second reinforcement ribs 14. The first reinforcement ribs 13 and the second reinforcement ribs 14 are arranged in a wavy line, and the protruding ends of the first reinforcement ribs 13 and the second reinforcement ribs 14 are fixedly connected to the upper elastic layer 9 and the lower elastic layer 10. A stable grid structure is formed by crossing the first reinforcement ribs 13 and the second reinforcement ribs 14. This structure can effectively disperse the pressure from different directions and provide a more comprehensive shock-absorbing effect. The wave-shaped reinforcement ribs can produce a better elastic response when impacted, similar to the effect of a spring, which helps to absorb the impact force and rebound quickly. The design of the cross reinforcement ribs increases the stability of the overall structure, especially when subjected to complex or multi-directional forces, which helps to improve the torsion resistance of the sole 2, thereby protecting the wearer's feet from injury.
[0032] Furthermore, the first reinforcing rib 13 and the second reinforcing rib 14 are made of polyimide material. Polyimide material has excellent heat resistance and can withstand high temperature environment, ensuring that the reinforcing rib can still maintain a stable structure and performance in a hot environment, which is particularly important for sports shoes in hot environments or long-term high-intensity exercise. In addition, polyimide material has excellent tensile strength and compressive strength, provides solid support, reduces the possibility of wear and damage, and extends the service life of the shoes.
[0033] Furthermore, several ventilation holes 7 are provided on the upper surface of the upper base 3. The design of the ventilation holes 7 allows air to freely circulate between the inside and the outside environment of the shoe, which helps to regulate the temperature and humidity inside the shoe, keep the feet dry, and improve the wearing comfort.
[0034] The embodiments of the present application have been described above in conjunction with the accompanying drawings. Without conflict, the embodiments and the features in the embodiments in the present application can be combined with each other. The present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative rather than restrictive.
