Detailed Description
The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Loofah has a network of network fibers in a porous network structure, which is of interest because of its good performance in resisting vibration and shock.
"shoe" means any type of garment for the foot, including but not limited to: all types of shoes, boots, athletic shoes, sandals, foot-clamping slippers, flip-flops, slippers, sleeping shoes, sandals, athletic specialized shoes (e.g., running shoes, golf shoes, tennis shoes, baseball shoes, soccer shoes, ski boots, basketball shoes, cross-training shoes, etc.), and the like.
In the related art, most of damping structures of shoes have regular crystal structures, and many defects exist, so this embodiment provides a shoe based on a vegetable sponge bionic structure. Referring to fig. 1 and 2, the shoe based on the loofah sponge bionic structure includes a shoe body 100 and a shock pad 200, wherein a receiving cavity 101 is provided at a heel of the shoe body 100, the shock pad 200 is installed in the receiving cavity 101, the shock pad 200 has a loofah sponge bionic structure formed by using TPU material and based on 3D printing or injection molding, the loofah sponge bionic structure includes a central portion 201 and an outer peripheral portion 202, and the bionic structure of the central portion 201 is denser than that of the outer peripheral portion 202. The TPU (Thermoplastic polyurethanes, thermoplastic polyurethane elastomer rubber) has excellent high-tension, tough and ageing-resistant characteristics, and is a mature environment-friendly material. Referring to fig. 3, fig. 3 shows a comparison chart of finite element analysis test results of a regular crystal structure 301 (shown in fig. 3 (a)) and a retinervus luffae fructus bionic structure 302 (shown in fig. 3 (b)), and it can be seen that the retinervus luffae fructus bionic structure of the embodiment has less deformation and better supporting performance under the same pressure condition. Referring to fig. 4, fig. 4 shows a comparison graph of deformation curves of a regular crystal structure (as shown in fig. 4 (a)) and a loofah sponge bionic structure (as shown in fig. 4 (b)) of the present embodiment, and it is known from the graph that under the same pressure condition, the loofah sponge bionic structure of the present embodiment has less rigid displacement, shorter deformation time, and better damping performance.
The damping pad 200 of the embodiment utilizes TPU material and forms a loofah sponge bionic structure based on 3D printing or injection molding, has better damping property and supporting performance, uses fewer materials, has lower cost, and can realize modularized design. It should be noted that, in this embodiment, the bionic structure of the retinervus luffae fructus is redesigned by using the bionic design, so that the bionic structure of the central portion 201 is denser than the bionic structure of the peripheral portion 202, and the damping structure is realized by using the 3D printing technology and the TPU material. The loofah bionic structure is an integrated structure, imitates the structure of the loofah, the central part 201 is densely structured and diverges to the outside, the gap of the structure is gradually increased, and the radius of the structure is unchanged. The structure accords with human engineering, and can provide stronger supportability, damping effect and quick rebound effect when the human body moves.
In some embodiments, the shock pad 200 has a pie shape, wherein the pie-shaped structure can be well adapted to the heel of a human body, the center portion 201 of the shock pad 200 having a pie shape is denser than the outer peripheral portion 202, and when the heel of the human body is in contact with the shock pad 200, the center portion 201 of the shock pad 200 corresponds to the position of the heel of the human body, which can provide good support performance for the human body. And the cake-shaped structure can uniformly disperse the received pressure, so that the damping effect is further improved. The upper and lower sides of the shock pad 200 have circumferential rims 203, the circumferential rims 203 are connected with an irregular grid structure, the circumferential rims 203 form a basic shape of the shock pad 200, and the circumferential rims 203 can provide a connection basis for the internal grid structure. The node gap of the grid structure gradually increases from the central portion 201 to the peripheral portion 202, and the outer side of the shock pad 200 is coated with an outer wrapping layer, wherein the outer wrapping layer may be an attachment coated on the outer side of the shock pad 200, or is sleeved on the outer side of the shock pad 200, and the outer wrapping layer is convenient for coating an adhesive material, so that the shock pad 200 is adhered to the shoe body 100. Compared with the related art, the shock pad 200 of the embodiment can be used as an independent module by 3D printing or injection molding, and can be applied to different footwear products, so that the shock pad 200 is suitable for different types of shoes by modular design, and the size is changed according to the requirements of actual products, thereby being beneficial to improving the applicability thereof.
In some embodiments, the shoe body 100 includes a sole 102 of unitary construction, the sole 102 being provided with a hollowed out structure 103 that serves as a receiving cavity 101, the hollowed out structure 103 may provide less material, lighter weight, and may provide more cushioning structure, facilitating improved cushioning. The shock pad 200 is adhered to the shoe body 100, and the connection mode is simple, so that the shock pad is suitable for more products.
The above embodiments are only preferred embodiments of the present utility model, and the scope of the present utility model is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present utility model are intended to be within the scope of the present utility model as claimed.
