Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.

Furthermore, in the present disclosure, unless explicitly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact of the first and second features, or may comprise contact of the first and second features not directly but through another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature. The terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1, an anti-soil leather rear cover for electronic products, including substrate layer 1, the upper surface of substrate layer 1 is equipped with one deck leather layer 2, and the surface coating on leather layer 2 has anti-soil layer 3, and the lower surface of substrate layer 1 is equipped with printing layer 4, and printing layer 4 is 3D printing layer or photochromic 3D printing layer or thermochromic 3D printing layer, and the bottom surface of printing layer 4 is equipped with printing bottom colour layer 5, and the bottom surface of printing bottom colour layer 5 has stratum basale 6 through hot pressing or adhesive bonding.

Above-mentioned embodiment provides a lid behind anti-soil leather for electronic product, thereby cover behind the completion can cover this whole hot briquetting directly obtains electronic product leather after the preparation subsides, can not appear that kind because of cover behind the leather layer laminating the shaping electronic product behind the curved edge that causes and the tensile line deformation scheduling problem of arc top, solved the unable printing problem on current leather surface anti-soil layer simultaneously, compare in the process of lid pad pasting again behind the shaping electronic product earlier, the utility model discloses a process method efficiency is higher, more be favorable to improving productivity and product quality.

In addition, through setting up the 3D printing layer, can be according to the corresponding pattern of customer's required printing or line, make the pattern of lid behind the cell-phone have bore hole 3D's effect, if adopt photochromic 3D printing layer or warm photochromic 3D printing layer moreover, then can make lid behind the cell-phone take place the colour change after receiving the stimulus of ambient light or temperature to further promote pleasing to the eye effect. It is worth mentioning that the anti-pollution layer 3 coated on the surface of the leather layer 1 in the structure can also realize the effects of resisting pollution, preventing burst and buffering and preventing falling crack.

It should be noted that, as those skilled in the art should know, the photochromic 3D printing layer or the thermochromic 3D printing layer, i.e., the 3D printing layer provided with the photochromic material or the 3D printing layer provided with the thermochromic material, since the photochromic material and the thermochromic material are known materials in the prior art, there is no technical obstacle for those skilled in the art to add the above materials to the bulk material of the 3D printing layer.

Preferably, the leather layer 2 is made of PU or silica gel, and when the leather is disposed on the material, the selected method may be to coat the PU or silica gel on embossed paper or an embossed film with leather texture to be cured and formed, and then tear off the embossed paper or the embossed film, so that the obtained leather layer 2 may have the leather texture.

When the silica gel material is used for manufacturing the leather layer 2, the temperature resistance and the environment protection are superior to those of the traditional PVC or other artificial leathers, and the silica gel material can not be softened during hot press molding, so that the undesirable products of disappearance and shallowness of veins and the like are avoided.

More preferably, the substrate layer 1 is made of PC or PET or glass fiber board or TPU material; or the substrate layer 1 is made of PC and PMMA materials together. The glass fiber board adopted as the organic composite board has good deformation resistance and falling resistance, is superior to the traditional non-base material materials such as ceramic, toughened glass and the like, is also superior to the common organic board, and further, the base material layer 1 is semitransparent or fully transparent.

In addition, in the present embodiment, the base layer 6 is also made of PC or PET or glass fiber board or TPU material; or the substrate layer 6 is made of PC and PMMA materials together.

The above-mentioned embodiment is the utility model discloses the implementation scheme of preferred, in addition, the utility model discloses can also realize by other modes, any obvious replacement is all within the protection scope of the utility model under the prerequisite that does not deviate from this technical scheme design.
