[0043] The utility model embodiment discloses an elastic pad, see Figure 1 , comprising at least two elastomers 11 spliced together along the horizontal direction, and an embodiment of the elastomer 11 is seen from Figure 2 、 Figure 3 and Figure 4, through the splicing of at least two elastic bodies 11, so that the area of the elastic body 11 can be expanded to the actual required extent, not limited by the single production size of the elastic body 11, so as to meet the large area demand, such as: mattress, sofa cushion, fitness mat (yoga, rope skipping), moisture-proof mat, carpet mat, protective mat for sports (such as high jump, horse, rings, horizontal bar, parallel bars, gymnastics), meditation mat, foot mat, tatami mat, kneeling mat, crawling mat, standing anti-fatigue mat (kitchen, workshop, standing post, etc. Long-term standing place), hemorrhoid seat cushion, etc.

[0044] Continuing to refer to Figure 1 , after splicing, the upper surface of the at least two elastic bodies 11 constitutes the upper surface of the elastic mat 1, and the lower surface of the at least two elastic bodies 11 constitutes the lower surface of the elastic mat 1, so as to ensure that the upper and lower surfaces of all the elastic bodies 11 are flush after splicing, and ensure the flatness of the elastic mat 1.

[0045] Continuing to refer to Figure 2 、 Figure 3 and Figure 4 , the elastic body 11 only includes a lattice structure, and the elastic mat 1 only includes the elastic body 11 with the lattice structure, which does not contain other structures and materials, and only needs to be processed and spliced from the process. Lattice structure elastic body 11, no longer needs various preparation and assembly processes of other structures and materials.

[0046] The rigidity of the elastic body 11 gradually increases from top to bottom, so that the upper part obtains relatively larger deformation to provide comfort, and the lower part obtains relatively smaller deformation to provide support. By designing the rigidity, the support and comfort are met. When subjected to pressure from top to bottom, the lower part has relatively large rigidity and small deformation to obtain sufficient support, and the upper part has relatively small rigidity and large deformation to obtain sufficient comfort.

[0047] In order to obtain the performance that the rigidity of the elastic body 11 gradually increases from top to bottom, at least one of the following modes can be used:

[0048] The cross-sectional area of the solid part 111 of the lattice structure gradually decreases from top to bottom, and the cross-sectional area of the solid part is changed to achieve the purpose of rigidity adjustment;

[0049] The volume of the hollow part 112 of the lattice structure gradually increases from top to bottom, and the volume of the hollow part is adjusted to achieve the purpose of rigidity adjustment;

[0050] The elastic modulus of the solid part of the lattice structure gradually decreases from top to bottom, and different materials and / or different preparation processes (for example, when the lattice structure is made by light curing 3D printing, the change of process parameters such as radiation intensity and radiation time) are used, so that the solid part in the upper and lower directions has different elastic modulus.

[0051] The elastic body 11 with lattice structure is made by light-cured 3D printing. It can be integrally formed and meet the requirements of parameterized design.

[0052] The adjacent elastic bodies 11 are fixed by bonding. No other structure is used, the process is simple and the cost is low. A specific way of bonding is that the adjacent elastic bodies 11 are fixed by bonding through the light-cured resin cured by using a curing box. That is, at least two elastic bodies 11 (the number of elastic bodies 11 shown in the figure is 50, which are spliced in the form of a 5-row 10-column rectangular array, of course, they can also be two, three or other numbers, and the splicing method can be flexibly selected according to the shape of the elastic pad 1) of the spliced elastic pad 1 are bonded.

[0053] A specific form of the lattice structure, referring to Figure 2 、 Figure 3 and Figure 4 , which includes a central part 113 and an edge part 114, the central part 113 includes a central solid part 1131 of a hexagonal frame, a central hollow part 1132 formed in the central solid part 1131; the edge part 114 includes an edge solid part 1141 of a hexagonal frame, an edge hollow part 1142 formed in the edge solid part 1141. The central solid part 1131 and the edge solid part 1141 provide rigidity, and the central hollow part 1132 and the edge hollow part 1142 provide space for deformation and air permeability, thereby meeting the design requirements (the lower part of the elastic body 11 has greater rigidity and thus smaller deformation to provide stable support, and the upper part of the elastic body 11 has smaller rigidity and thus greater deformation to provide comfort).

[0054] Referring to Figure 3 and Figure 4 , the first edge of the edge solid part 1141 coincides with one edge of the first central solid part 1131, the remaining four edges of the edge solid part 1141 coincide with the four edges of the other four adjacent edge parts 114, and the sixth edge of the edge solid part 1141 coincides with one edge of the second central solid part 1131. The edges shared by the two edge solid parts 1141 connected between the two adjacent central solid parts 1131 extend horizontally. The coinciding edges are arranged horizontally and form a pulling effect in the horizontal direction, which can increase the stress area when the elastic body 11 is partially pressed, thereby horizontally diffusing the local pressure; the other edges of the non-coinciding edges are arranged obliquely, forming multiple transmission paths of force (along the length direction of the non-coinciding edges).

[0055] The cross-sectional area of the exposed surface solid part 1111 of the elastomer is less than the cross-sectional area of the internal solid part 1112 of the elastomer. Since the adjacent exposed surface solid part 1111 of the elastomer needs to be spliced, the cross-sectional size after splicing of the splicing surface will increase (to the cross-sectional area of the two solid parts + the cross-sectional area of the light-cured resin cured by the curing box), which is not desirable to occur, because the increase will make the rigidity of the edge (exposed surface) of the elastomer 11 (at the same height) greater than the internal part, causing a sudden increase in rigidity. Therefore, the inventors make the setting that the cross-sectional area of the exposed surface solid part 1111 of the elastomer is less than the cross-sectional area of the internal solid part 1112 of the elastomer, when the above relationship is <, the cross-sectional size increase can be effectively reduced. In particular, the setting is made that the cross-sectional area of the two solid parts + the cross-sectional area of the light-cured resin cured by the curing box = the cross-sectional area of the internal solid part of the elastomer 11, so that the rigidity after splicing of the splicing surface is consistent with the rigidity of the internal part, thereby ensuring the consistency of the support and comfort of the entire elastomer pad 1 at the same height.

[0056] The above-described embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements for some technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application.
