Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention without any inventive step, are within the scope of protection of the invention.

Referring to fig. 1 and 2, a lattice-type sole 100 is provided according to a first embodiment of the present invention. The lattice-type sole 100 includes a first lattice region 110 and a second lattice region 120. The first lattice region 110 and the second lattice region 120 are distributed in the horizontal direction of the lattice-type sole 100. The first patterned areas 110 are located at the rear ball of the foot for providing higher support performance and the second patterned areas 120 are located at the front ball of the foot for providing higher rebound damping performance.

Referring to fig. 3 and 4, the first lattice structure 111 of the first lattice region 110 is a four-leaf rhombus stacked structure with a volume ratio of 34.9/200; the second lattice structure 121 of the second lattice region 120 is a truncated octahedral structure having a volume ratio of 27.8/200. Wherein the volume ratio is 200mm³(10 mm by 2 mm) is the basis of the measurement. The first lattice structure 111 has a higher structure density than the second lattice structure 121. In the connection region between the first lattice region 110 and the second lattice region 120, the first lattice structures 111 and the second lattice structures 121 are connected in a one-to-one correspondence. Wherein the four first vertex points 1111a of the first connection surface 1111 of the first lattice structure 111 and the second latticeThe four second apex points 1211a of the second connection surface 1211 of the structure 121 correspond to one another, and the first center point 1111b of the first connection surface 1111 of the first lattice structure 111 and the second center point 1211b of the second connection surface 1211 of the second lattice structure 121 correspond to each other. Therefore, the first lattice region 110 and the second lattice region 120 can be connected with each other accurately and tightly by the accurate alignment.

In the internal connection relationship of the first lattice region 110, two adjacent unit cells of each first lattice structure 111 are connected to each other through four vertices and a face center of a contact face of the two adjacent unit cells. Further, in the vertical direction, the rod diameter size of the first lattice structure 111 of the first lattice region 110 increases in order from top to bottom in the vertical direction to achieve a linear footfeel. The rod diameter dimensions of the first lattice structure 111 lie in the range of 0.7 mm to 2 mm. In the internal connection relationship of the second lattice region 120, two adjacent unit cells of each second lattice structure 121 are connected to each other through four vertices and a face center of a contact face of the two adjacent unit cells. Further, in the vertical direction, the rod diameter size of the second lattice structures 121 of the second lattice region 120 increases in the vertical direction from top to bottom in order to achieve a linear foot feel. The rod diameter dimension of the second lattice structure 121 lies in the range of 0.7 mm to 2 mm. In other embodiments, the rod diameters of the first lattice structure 111 and the second lattice structure 121 do not necessarily increase sequentially from top to bottom in the vertical direction, but the rod diameters may be adjusted to adapt to different stress characteristics of the front and rear hands, so as to achieve comfort and stability.

Referring to fig. 5 and 6, a lattice-type sole 200 is provided according to a second embodiment of the present invention. Waffle sole 200 includes a first patterned area 210, a second patterned area 220, and a third patterned area 230. The first lattice region 210, the second lattice region 220 and the third lattice region 230 are sequentially distributed in the vertical direction of the lattice sole 200. The first lattice region 210 is located below the second lattice region 220, and the third lattice region 230 is located above the second lattice region 220.

With further reference to FIG. 7, the first lattice structure 211 of the first lattice region 210 isA four-leaf diamond stack structure with a volume ratio of 34.9/200; the second lattice structure 221 of the second lattice region 220 is a truncated octahedron structure with a volume ratio of 27.8/200; the third lattice structure 231 of the third lattice region 230 is a diamond-like molecular structure with a volume ratio of 14.6/200. Wherein the volume ratio is 200mm³(10 mm by 2 mm) is the basis of the measurement. The first lattice structure 211 has a higher structure density than the second lattice structure 221, and the first lattice structure 211 has a shorter average rod length than the second lattice structure 221 for providing a stronger supporting performance. The second lattice structure 221 has a polyhedral inner space structure for providing high shock-absorbing performance. The third lattice structure 231 has a lower structure density than the second lattice structure 221 for providing a soft contact property. The lattice sole of the present embodiment is suitable for casual footwear.

In the connection region between the first lattice region 210 and the second lattice region 220, the first lattice structures 211 are connected to the second lattice structures 221 in a one-to-one correspondence. Four first vertex points 2111a of the first connection surface 2111 of the first lattice structure 211 correspond to four second vertex points 2211a of the second connection surface 2211 of the second lattice structure 221 one-to-one, and a first center point 2111b of the first connection surface 2111 of the first lattice structure 211 corresponds to a second center point 2211b of the second connection surface 2211 of the second lattice structure 221. In the connection region between the second lattice region 220 and the third lattice region 230, the second lattice structures 221 are connected to the third lattice structures 231 in a one-to-one correspondence. Four first top corner points 2211a of the second connection surface 2211 of the second lattice structure 221 correspond to four third top corner points 2311a of the third connection surface 2311 of the third lattice structure 231 one to one, and a first center point 2211b of the second connection surface 2211 of the second lattice structure 221 corresponds to a third center point 2311b of the third connection surface 2311 of the third lattice structure 231 one to one. Therefore, by such an accurate alignment, the mutual connection between the first lattice region 210 and the second lattice region 220 can be aligned accurately, and the mutual connection between the second lattice region 220 and the third lattice region 230 can be aligned accurately and tightly.

In other embodiments, the lattice structures used in the lattice regions can be freely arranged and combined according to different use scenes or motion characteristics. For example, the running shoe may use the combination of the second lattice structure 221, the third lattice structure 231, and the second lattice structure 221 in order from top to bottom in the vertical direction to provide better rebound and cushioning properties; the basketball shoe may use the combination of the second lattice structure 221, the third lattice structure 231 and the third lattice structure 231 in the vertical direction from top to bottom in order to provide relatively strong resilience and support performance, so that the foot feel can be more rapidly responded. In addition, in further embodiments, the lattice region may also not be limited to a three-layer structure, and more layers of lattice structures may be adopted to implement more functions to adapt to more application scenarios.

The crystal-format sole provided by the embodiment of the invention is manufactured by adopting a 3D printing technology. A 3D printing technique that may be used with embodiments of the present invention is Selective Laser Sintering (SLS). Selective Laser Sintering (SLS) uses primarily an infrared laser as an energy source to shape powdered materials. In the actual production, the powder material is preheated in the first step; when the temperature of the powder material is raised to be slightly lower than the melting point of the powder material, implementing a second step of flattening the powder material by using a scraping roller; thirdly, selectively sintering the powder material after the leveling treatment by using an infrared laser beam under the control of a computer, wherein the selective sintering is mainly operated according to the layered section information provided by the computer, and actually, the sintering operation of the lower layer is generally performed after the sintering of the upper layer is finished; and fourthly, removing redundant powder after all the powder layers are completely sintered, thereby finishing the finished product of the crystal-form sole made by the 3D printing technology. Furthermore, in the embodiment of the present invention, the 3D printing material of the lattice-type shoe sole uses thermoplastic polyurethane resin (TPU) powder. Thermoplastic Polyurethane (TPU) is a copolymer of hard and soft block materials that has high tensile and abrasion resistance properties, as well as excellent elasticity and biological identity.

In other embodiments, the 3D printing technique of the waffle-style shoe sole may also use Digital Light Processing (DLP). Digital Light Processing (DLP) is mainly used for carrying out digital processing on image signals, and then carrying out photocuring processing on liquid photopolymer layer by using a high-resolution Digital Light Processor (DLP) projector according to data information so as to finish a finished product of the sole in a crystal format, which is manufactured by a 3D printing technology. For the 3D printing material of the lattice-type shoe sole, a Polyurethane (PU) type photo-curable resin material may also be used. Polyurethane (PU) is a polymer with repeating structural units of urethane segments made from the reaction of isocyanate with polyol, and also has high tensile and abrasion resistance properties, as well as excellent elasticity and biological identity.

According to the lattice-type sole provided by the embodiment of the invention, the first lattice region and the second lattice region with different structure densities are adopted, so that different regions of the sole have different stress characteristics, and a better wearing comfort level is provided for a wearer.

Accordingly, the scope of the present disclosure is not limited to the above-described embodiments, but should be determined by the claims and the equivalents thereof.
