[0020] In order to make the purpose, the technical scheme and the advantages of the utility model more clear and obvious, the utility model will be further described in detail below in combination with the drawings and the 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.

[0021] For example, Figures 1 to 3The utility model provides a kind of reverse package 3D printing cushion, the middle part of the reverse package 3D printing cushion is provided with a through hole 100.The reverse package 3D printing cushion includes cushion body 10, pedestal 20 and sitting arch 30, the sitting arch 30 is arranged on the bottom surface of pedestal 20, the cushion body 10 is covered on the top surface of pedestal 20, and the outer side edge of cushion body 10 is wrapped in cushion body 10 downwards with the edge of pedestal 20.The through hole 100 penetrates cushion body 10 and pedestal 20.In the embodiment, the cushion body 10 is 3D printing molding.

[0022] The cushion body 10 includes bottom plate 11, hollow part 12 and edge covering part 13, the hollow part 12 is arranged above bottom plate 11, and the hollow part 12 is consistent with the shape of bottom plate 11.The hollow part 12 is an overall hollow structure, which is combined by a plurality of support strips 121, and a plurality of polygonal hollow holes are formed by enclosing between a plurality of upper and lower and left and right adjacent support strips 121.In the embodiment, the support strip 121 inside the hollow part 12 is cylindrically arranged, and the outer surface of the outermost support strip 121 is flatly arranged.The outer surface of cushion body 10 is smooth and flat, improving the comfort during use.

[0023] The edge covering part 13 is arranged on the outermost edge of bottom plate 11, and the edge covering part 13 is annularly arranged, forming an annular limiting groove 131 between the bottom surface of bottom plate 11 and the edge covering part 13, and the outer edge of pedestal 20 is embedded in the limiting groove 131.Further, the size of bottom plate 11 is greater than that of pedestal 20, and a flange 111 is formed on the outer periphery edge of bottom plate 11, and the outer surface of the edge covering part 13 is inclinedly and inwardly arranged towards the direction of pedestal 20;the limiting groove 131 and the edge covering part 13 form an inner buckle structure, which can further improve the stability of the edge covering part 13 limiting the pedestal 20, so that the edge covering part 13 is not easy to turn outwards and separate from the pedestal 20.Ignoring the separation problem between the edge covering part 13 and the pedestal 20, the opening part is still inside the lower part of the pedestal 20 after repair, which does not affect the appearance and comfort.

[0024] The sitting arch 30 is limitedly installed on the pedestal 20 by the first mounting part 41 and the second mounting part 42, and in the embodiment, the first mounting part 41 and the second mounting part 42 are respectively arranged at the front and rear ends of the sitting arch.In detail, an installation groove is arranged on the inner side surface of the first mounting part 41, and the sitting arch 30 is embedded in the installation groove.The second mounting part 42 is arcuately arranged, and the second mounting part 42 is pressed and limited on the pedestal 20.The first mounting part 41 and the second mounting part 42 can be fixed by screws or adhesive.

[0025] As Figure 4As shown, it is the second embodiment of the utility model, the structure of this embodiment is basically same with the first embodiment, the difference is that: the outermost side of the base 20 is provided with annular convex part 21, when installing, the rim of the base 20 is clamped into the limiting groove 131, the annular convex part and the edge covering part 13 form a buckle structure, so that the stability of installation can be further improved. After installation, the edge covering part 13 and the bottom surface of base 20 are further bonded by adhesive layer.

[0026] As Figure 5 With Figure 6 As shown, it is the third embodiment of the utility model, the structure of this embodiment is basically same with the first embodiment, the difference is that: the outer side of the first mounting piece 41 is provided with first limiting step part 411, the inner and outer sides of the second mounting piece 42 are provided with second limiting step part 422, the bottom surface of the first limiting step part 411 and the second limiting step part 422 are flush with the top surface of the edge covering part 13;So the edge covering part 13 can be further limited.

[0027] In summary, the cushion body 10 of the utility model adopts 3D printing structure, the top and periphery of the cushion body 10 are hollow, which is not only convenient to process, but also saves materials, and the cushion is breathable and comfortable. By setting the edge covering structure, the installation between the cushion body 10 and the base 20 is more stable, and there is no process gap in appearance, which is more beautiful. The utility model has strong practicability and strong popularization significance.

[0028] The above-described embodiments only express three kinds of implementation manners of the utility model, and the description is more specific and detailed, but it should not be understood as the limitation of the patent range of the utility model.
