Description

Technical Field

[0001] The utility model belongs to the technical field of 3D printed shoes, and specifically relates to a 3D printed shock-absorbing shoe. Background Art

[0002] Sports shoes are a type of shoe designed specifically for sports or outdoor activities. They have the following characteristics: the soles are soft and elastic, which can provide a certain cushioning effect, enhance flexibility during exercise, and help prevent ankle injuries. The uppers are mostly made of breathable materials to keep the feet dry and comfortable and prevent sweat accumulation. The design of the shoes focuses on stability and support to provide adequate support and protection and reduce the risk of sports injuries. In addition, sports shoes are also subdivided according to different sports and needs, such as running shoes, basketball shoes, football shoes, etc., to meet the special requirements of different sports for shoes.

[0003] At present, sports shoes have to withstand greater foot pressure and recoil from the ground, so there are higher requirements for their shock absorption performance. Existing sports shoes generally install auxiliary shock absorption structures such as air cushions or air bags on the soles to improve the shock absorption performance. The shock absorption effect is not obvious, and the sole structure is relatively complex and increases weight, which makes processing inconvenient, and the shoes cannot meet the lightweight requirements. Utility Model Content

[0004] The utility model aims to provide a 3D printed shock-absorbing shoe to solve the shock-absorbing and lightweight problems in the prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A 3D printed cushioning shoe, comprising a shoe body and a printed sole, wherein the shoe body and the printed sole are integrally printed, the printed sole comprises a lower shoe body, an upper shoe body front end, an upper shoe body rear end and a node, and the upper shoe body front end is connected to the printed sole through the node;

[0007] The front end of the upper shoe body and the rear end of the upper shoe body form a rebound zone with the lower shoe body;

[0008] A shock absorbing component for limiting the rebound interval distance is provided between the front end and the rear end of the upper shoe body and the lower shoe body.

[0009] Furthermore, the shock-absorbing component includes support blocks, and several of the support blocks are distributed and supported between the front end and the rear end of the upper shoe body and the lower shoe body. Reinforcing columns are connected to the support blocks to improve the rebound support performance of the support blocks; the support blocks are cross-supported between the front end and the rear end of the upper shoe body and the lower shoe body.

[0010] In the above scheme, the pressure generated by the wearer's foot is transmitted downward from the front end and the rear end of the upper shoe body to the crossed support blocks, which support and absorb the power generated by the foot, thereby providing a shock-absorbing effect. A triangular structure is formed between the upper and lower crossed support blocks, thereby strengthening the supporting effect between the front end and the rear end of the upper shoe body and the lower shoe body.

[0011] Furthermore, each support block forms an upper, lower, left and right area after crossing, and reinforcement columns are distributed around the area formed after the support blocks cross. The deformed support block will be restricted in deformation space by the reinforcement column, and at the same time, when the support block rebounds, the reinforcement column absorbs the force of the support block's automatic rebound, and the reinforcement column and the support block restrict each other, which greatly reduces the shock absorbing effect of the utility model.

[0012] Furthermore, the reinforcing column is arranged in a circular or elliptical shape. The circular or elliptical structure is used to surround the support block, which can improve the resetting deformation capacity of the cross support block. The circular or elliptical shape acts around the support block in an arc shape. The arc structure has good elasticity and compression resistance, and can effectively absorb and alleviate vibration and impact force.

[0013] Furthermore, ventilation holes are provided through the front end and rear end surfaces of the upper shoe body.

[0014] In the above, the ventilation holes are the contact positions of the soles of the feet. When the user wears the shoes, the ventilation can be circulated and comfortable, and the shoes are easy to wear for three-dimensional ventilation. The ventilation holes can make the ventilation space larger and the ventilation effect better; increase the torsion resistance of the shoes: the ventilation holes can increase the torsion resistance of the shoes; facilitate moisture-proof: the ventilation holes are conducive to the discharge of foot sweat, allowing the shoes to dry quickly and keep the feet dry; reduce the weight of the shoes: the ventilation holes can reduce the weight of the shoes and make them more comfortable to wear; in addition, the ventilation holes on the soles also have the functions of protecting the shoes and eliminating odors.

[0015] The technical solution of the utility model has the following beneficial effects:

[0016] 1. The front end and the rear end of the upper shoe body form a rebound zone with the lower shoe body, and the rebound zone can facilitate the front end and the rear end of the upper shoe body to generate space for downward displacement when the user wears the shoe body.

[0017] 2. The support blocks support and absorb the power generated by the foot, that is, provide a shock-absorbing effect. A triangular structure is formed between the upper and lower crossed support blocks to strengthen the support effect between the front end of the upper shoe body and the rear end of the upper shoe body and the lower shoe body. Each support block forms an upper, lower, left and right interval after crossing, and a reinforcing column is arranged in the upper, lower, left and right intervals formed after crossing. The deformed support block will have its deformation space limited by the reinforcing column. At the same time, when the support block rebounds, the reinforcing column absorbs the force of the automatic rebound of the support block. The reinforcing column and the support block restrict each other, which greatly reduces the shock-absorbing effect of the utility model and enables the wearer to have a better comfort experience.

[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] refer to Figures 1 to 3A 3D printed cushioning shoe comprises a shoe body 10 and a printed sole 20. The shoe body 10 and the printed sole 20 are integrally printed and formed, eliminating the use of chemical glue, making the production process healthier and safer, reducing manual operation processes, improving production efficiency, and driving the industrialization upgrade of shoe companies. 3D printing technology can quickly manufacture customized shoes that meet the needs of consumers based on their individual foot shape data, and can provide consumers with more comfortable and suitable shoes. Lightweight design is carried out according to the needs of different parts to reduce the overall weight of the shoes, which is conducive to reducing the burden on the wearer, improving wearing comfort, and improving sports performance to a certain extent. 3D printed shoes only need to manufacture the required materials according to demand, reducing waste and resource waste, and being more environmentally friendly. The printed sole 20 comprises a lower shoe body 21, an upper shoe body front end 22, an upper shoe body rear end 25, and a node 23. The upper shoe body front end 22 is connected to the printed sole 20 through the node 23;

[0027] The 3D printing materials adopted by the utility model are bendable fibers, recycled polyester and the like.

[0028] Further references Figure 3 The front end 22 and the rear end 25 of the upper shoe body form a rebound area 24 with the lower shoe body 21. The rebound area 24 can facilitate the front end 22 and the rear end 25 of the upper shoe body to generate space for downward displacement when the user wears the shoe body 10; a shock-absorbing component for limiting the distance of the rebound area 24 is provided between the front end 22 and the rear end 25 of the upper shoe body and the lower shoe body 21.

[0029] Further references Figure 2 The shock-absorbing component includes support blocks 26. Several support blocks 26 are distributed and supported between the front end 22 and the rear end 25 of the upper shoe body and the lower shoe body 21. The support blocks 26 are cross-supported between the front end 22 and the rear end 25 of the upper shoe body and the lower shoe body 21. When the wearer wears the utility model, the pressure generated by the wearer's foot is transmitted downward from the front end 22 and the rear end 25 of the upper shoe body to the crossed support blocks 26, and the support blocks 26 support and absorb the power generated by the foot, that is, provide a shock-absorbing effect. A triangular structure is formed between the upper and lower cross support blocks 26 to strengthen the support effect between the front end 22 and the rear end 25 of the upper shoe body and the lower shoe body 21.

[0030] Further references Figure 1, the support block 26 is connected with a reinforcing column 27 to improve the rebound support performance of the support block 26. Each support block 26 forms an upper, lower, left and right interval after crossing. The reinforcing column 27 is distributed around the interval formed by the crossing of the support block 26. When the support block 26 is deformed by force during the movement of the wearer, the reinforcing column 27 is arranged in the upper, lower, left and right intervals formed after crossing. The deformed support block 26 will be restricted by the reinforcing column 27. At the same time, when the support block 26 rebounds, the reinforcing column 27 absorbs the force of the automatic rebound of the support block 26. The reinforcing column 27 and the support block 26 restrict each other, which greatly reduces the shock absorbing effect of the utility model, so that the wearer has a better comfort experience effect;

[0031] Combination Figure 1 In the embodiment, the reinforcing column 27 is set between the rear end 25 of the upper shoe body and the lower shoe body 21. The distance of elastic deformation between the rear end 25 of the upper shoe body and the lower shoe body 21 is large, and the reinforcing column 27 is used to limit and offset the vibration effect of a large part. However, there is no reinforcing column 27 between the front end 22 of the upper shoe body and the lower shoe body 21. The deformation between the front end 22 of the upper shoe body and the lower shoe body 21 is small, and the support block 26 is sufficient to achieve a shock absorbing effect, saving printing materials. The front end 22 of the upper shoe body is the contact position of the sole of the foot, and the rear end 25 of the upper shoe body is the contact position of the heel.

[0032] Furthermore, the reinforcing column 27 is arranged in a circular or elliptical shape. The circular or elliptical structure is used to surround the support block 26, which can improve the resetting deformation ability of the cross support block 26. The circular or elliptical shape acts around the support block 26 in an arc shape. The arc structure has good elasticity and compression resistance, and can effectively absorb and relieve vibration and impact force.

[0033] Embodiment 2:

[0034] refer to Figure 4 The front end 22 and the rear end 25 of the upper shoe body are penetrated with ventilation holes 28. The ventilation holes 28 are the contact positions of the soles of the feet. When the user wears the shoes, the ventilation holes 28 are circulated and ventilated, and the shoes are comfortable and cozy to wear. The ventilation holes 28 are convenient for three-dimensional ventilation. The ventilation holes 28 can make the ventilation space larger and the ventilation effect better; increase the torsion resistance of the shoes: the ventilation holes 28 can increase the torsion resistance of the shoes; facilitate moisture-proof: the ventilation holes 28 are conducive to the discharge of foot sweat, allowing the shoes to dry quickly and keep the feet dry; reduce the weight of the shoes: the ventilation holes 28 can reduce the weight of the shoes and make them more comfortable to wear; in addition, the ventilation holes 28 on the soles also have the functions of protecting the shoes and eliminating odors.

[0035] The specific implementation process of this embodiment is as follows:

[0036] When the wearer wears the utility model, the pressure generated by the wearer's foot is transmitted downward from the front end 22 and the rear end 25 of the upper shoe body to the cross support block 26, and the support block 26 supports and absorbs the power generated by the foot, that is, provides a shock absorbing effect. The cross support block 26 forms a triangular structure between the upper and lower parts, thereby strengthening the support effect between the front end 22 and the rear end 25 of the upper shoe body and the lower shoe body 21;

[0037] During the movement of the wearer, the support block 26 is deformed by the force, and the reinforcing columns 27 are arranged in the upper, lower, left and right intervals after the intersection. The deformed support block 26 will be restricted in deformation space by the reinforcing columns 27. At the same time, when the support block 26 rebounds, the reinforcing columns 27 absorb the force of the automatic rebound of the support block 26. The reinforcing columns 27 and the support block 26 restrict each other, which greatly reduces the shock-absorbing effect of the utility model and allows the wearer to have a better comfort experience.
