[0031] The present utility model provides a mobile phone case.

[0032] Please refer to Figures 1 to 2 , in an embodiment of the present utility model, the mobile phone case includes:

[0033] A bottom plate 100 and an outer frame 200. The outer frame 200 is disposed around the circumference of the bottom plate 100 and encloses with the bottom plate 100 to form a receiving cavity 21 with an opening on one side for receiving a mobile phone;

[0034] A composite coating group 300 is provided on the back of the bottom plate 100 away from the receiving cavity 21. The composite coating group 300 includes a metal reflective layer 33 and a pattern printing layer 34; the metal reflective layer 33 is disposed on the side of the bottom plate 100 facing away from the receiving cavity 21, and part of the pattern printing layer 34 is disposed on the bottom plate 100, and part of the pattern printing layer 34 covers the metal reflective layer 33.

[0035] In the technical solution of the present utility model, the pattern printing layer 34 is coated on the metal reflective layer 33 and the base lining layer 31, so that the texture and color of the printing pigment of the pattern printing layer 34 can form a contrast with the metal effect presented by the metal reflective layer 33, making the pattern printing layer 34 have a visual effect of floating above the metal reflective layer 33, so as to visually form a 3D stereoscopic effect.

[0036] In an embodiment, the metal reflective layer 33 includes a linear reflective texture structure 331 and a planar pattern structure. Multiple metal lines 332 are arranged on the linear reflective texture structure 331, and the planar pattern structure is an integral smooth pattern. In the linear reflective structure, there are various arrangements of the metal lines 332. For example, when the metal lines 332 are arcs, and multiple arcs are arranged in an annual ring shape or a fingerprint shape; when the metal lines 332 are curves, multiple curves bend and extend in the same direction, and during the extension process, adjacent lines approach or separate from each other during the extension process, and the curves can approach each other to coincide; when the metal lines 332 are curves, it can also be that the bending directions of multiple curves are the same, and they are arranged at uniform intervals in the non-extension direction; when the metal lines 332 are straight lines, for adjacent straight lines in the extension direction of a straight line, their extension directions intersect with the normal direction of the extension of this straight line, and adjacent straight lines are arranged at uniform intervals in the left and right directions of a straight line. Further, the straight lines protrude; when the metal lines 332 are straight lines, it can also be that the metal lines 332 include multiple first straight lines extending in a first direction and multiple second straight lines extending in a second direction, and the first direction and the second direction intersect. Further, the metal lines 332 include a first line segment on the first straight line and a second line segment on the second straight line, and the first line segment and the second line segment do not intersect, or at least one first line segment intersects at least one second line segment. Further, both the first line segment and the second line segment are recessed. In the planar pattern structure 333, the planar cross-sectional shape includes a circle, an ellipse, a triangle, a quadrilateral, a random shape, a pentagram, a fruit shape, a hat shape, an ice cream cone shape, a cloud shape, etc.

[0037] It should be noted that since a part of the pattern printing layer 34 is coated on the metal reflective layer 33 and another part is coated on the base substrate layer 31, when the protective film 35 is coated on the pattern printing layer 34, the pattern printing layer 34 located above the metal reflective layer 33 is all coated with the protective film 35, while for the pattern printing layer 34 located on the base substrate layer 31, part of it is coated with the protective film 35 and another part is not coated with the protective film 35. After the pattern printing layer 34 is coated on the metal reflective layer 33, the coated metal reflective layer 33 can still show a metallic luster while having a color. After the protective film 35 is coated on this pattern printing layer 34, it can magnify the metallic luster, and thus generate a greater distinction from other pattern printing layers 34 coated on the base substrate layer 31, which is helpful for the formation of the 3D stereoscopic effect.

[0038] In one embodiment, a reflective film 11 is provided on the surface of the bottom plate 100 facing the accommodating cavity 21, and the material of the bottom plate 100 is configured as a transparent material. The reflective film 11 can refract colorful light. Therefore, when observing the bottom plate 100 from the side of the bottom plate 100 away from the accommodating cavity 21, gorgeous colors can be observed on the bottom plate 100. Moreover, since the colors and textures presented by the light reflection are different from the metallic luster of the metal reflective layer 33 and the pigment colors and textures of the pattern printing layer 34, the colorful light refracts from the side of the bottom plate 100 close to the accommodating cavity 21 to the side away from the accommodating cavity 21. Therefore, there are obvious differences in the display positions of the colors refracted by the reflective film 11 and the colors of the composite layer group 300 in the thickness direction of the bottom plate 100, so as to form a 3D stereoscopic effect with the colors of the composite layer group 300. Further, the reflective film 11 is configured as a transparent reflective film, so that colorful light can be refracted on both the side of the bottom plate 100 close to the accommodating cavity 21 and the side away from the accommodating cavity 21. Specifically, the reflective film 11 can be produced by means such as vacuum electroplating, vacuum sputtering, laser embossing, and coating process. There are many production and forming methods for it, which are not limited herein. In other embodiments, there may also be no reflective film 11. When the bottom plate 100 is produced and formed, a metal foil is placed inside the bottom plate 100 to display the colors of the refracted light on the back of the bottom plate 100 away from the accommodating cavity 21 and to form a 3D stereoscopic effect with the colors of the composite layer group 300.

[0039] In one embodiment, the pattern printing layer 34 includes a main pattern display area and a refractive texture area 341. Part of the main pattern display area 343 is disposed on the bottom plate 100, and part of the main pattern display area 343 covers the metal reflective layer 33. The refractive texture area 341 can refract the ambient light around the mobile phone case into the reflective film 11, and can refract the colorful light emitted by the reflective film 11 out of the bottom plate 100, effectively enhancing the light intensity of the colorful light emitted from the reflective film 11 out of the bottom plate 100, increasing the range of the emitted colorful light, so that when the human eye observes the back of the bottom plate 100 of the mobile phone case, the gorgeous colors of the colorful light and the laser pattern formed after the colorful light passes through the refractive texture area 341 can be easily seen from multiple angles. It should be noted that the refractive texture area 341 includes a plurality of refractive lines 342, the refractive lines 342 are convexly disposed on the bottom plate 100, and there are various arrangements of the plurality of refractive lines 342. For example, when the refractive lines 342 are straight lines, for the straight lines adjacent in the extending direction of a straight line, their extending directions intersect with the normal direction of the extension of this straight line, and the straight lines adjacent in the left and right directions of a straight line are arranged at equal intervals; when the refractive lines 342 are straight lines, it can also be that the refractive lines 342 include a plurality of third straight lines extending in a third direction and a plurality of fourth straight lines extending in a fourth direction, the third direction and the fourth direction intersect, and further, the refractive lines 342 include a third line segment on the third straight line and a fourth line segment on the fourth straight line, the third line segment and the fourth line segment intersect, or the first line segment and the second line segment do not intersect; when the refractive lines 342 are arcs, and the plurality of arcs are arranged in an annual ring shape or a fingerprint shape; when the refractive lines 342 are curves, the plurality of curves are bent and extended in the same direction, and during the extension process, the adjacent lines approach or separate from each other during the extension process, and the curves can approach each other to coincide; when the refractive lines 342 are curves, it can also be that the bending directions of the plurality of curves are the same, and they are arranged at equal intervals in the non-extending direction.

[0040] In one embodiment, the bottom plate 100 has a camera avoidance opening 12, and a surrounding edge 13 is provided at the position of the camera avoidance opening 12. The surrounding edge 13 is used to accommodate the rear camera of the mobile phone to protect the rear camera. The back of the base lining layer 31 corresponding to the surrounding edge 13 is provided with a refractive texture area 341. The surrounding edge 13 can effectively protect the rear camera protruding from the back of the mobile phone. The refractive texture area 341 can modify the structure clamped between the surrounding edge 13 and the edge of the bottom plate 100, so that the colorful light can be emitted at the transition connection between the surrounding edge 13 and the bottom plate 100, enhancing the aesthetic feeling of the mobile phone case. In other embodiments, the surrounding edge 13 may not be provided.

[0041] In one embodiment, the metal reflective layer 33 protrudes from the bottom plate 200, so that the pattern with metallic luster can visually highlight the pattern printing layer 34, which helps to give the pattern of the composite pattern layer a 3D stereoscopic effect. In other embodiments, the top end of the metal reflective layer 33 can also be horizontal with the top end of the pattern printing layer 34.

[0042] In one embodiment, the metal reflective layer 33 is configured as an aluminum foil. Aluminum has good metallic luster and excellent ductility, and can be extended into a thin aluminum foil, making the mobile phone case have better aesthetics and low production cost. In other embodiments, the metal reflective layer 33 can also be configured as a gold foil or a silver foil.

[0043] In one embodiment, the material of the metal reflective layer 33 is configured as electroaluminum. Electroaluminum is a hot stamping material made on a thin film substrate through coating and vacuum evaporation technology. Both the linear reflective texture structure 331 and the surface pattern structure 333 are formed by hot stamping on the electroaluminum with a hot stamping head. In other embodiments, various two-dimensional, three-dimensional, dot matrix, spiral and other images can also be embossed on the metal foil and then covered on the base lining layer 31.

[0044] In one embodiment, the composite coating group 300 further includes a protective film 35, and the protective film 35 is coated on the metal reflective layer 33 and at least part of the pattern printing layer 34. The protective film 35 can be used to protect the metal reflective layer 33 from being damaged, and can brighten the metallic luster of the metal reflective layer 33 and the colors of some patterns on the pattern printing layer 34, so that the patterns can have color differences, thereby creating a 3D stereoscopic effect. In other embodiments, the protective film 35 can also be coated on all the exposed metal reflective layer 33 and pattern printing layer 34, or the protective film 35 is not provided.

[0045] In one embodiment, the composite coating group 300 further includes a base lining layer 31, and the base lining layer 31 is arranged on the back of the bottom plate 100. The pattern printing layer 34 and the metal reflective layer 33 are both coated on the side of the base lining layer 31 away from the bottom plate 100. Coating the base lining layer 31 on the bottom plate 100 helps to fix the metal reflective layer 33 and the pattern printing layer 34 to the bottom plate 100 smoothly, making the patterns formed by coating the metal reflective layer 33 and the pattern printing layer 34 clean and beautiful. In other embodiments, the base lining layer 31 can also be not provided.

[0046] In one embodiment, the composite layer group 300 further includes an adhesive layer 32, which is sandwiched between the base lining layer 31 and the metal reflective layer 33 for bonding the base material layer and the metal reflective layer 33, so that the metal reflective layer 33 made of electro - aluminum can be fixedly connected to the base plate 100. It should be noted that after the flat electro - aluminum is adhered to the adhesive layer 32, the hot stamping head then stamps the electro - aluminum. In other embodiments, the adhesive layer 32 may not be provided, and the base lining layer 31 is combined with the electro - aluminum after stamping.

[0047] In one embodiment, the material of the base plate 100 is configured as one of acrylic, silicone, thermoplastic polyurethane, polycarbonate, acrylonitrile - butadiene - styrene copolymer, and polypropylene. That is to say, the material of the base plate 100 is configured as a plastic material. Coating a base lining layer 31 on the base plate 100 can prevent the color of the base plate 100 from interfering with the color display of the metal reflective layer 33 and the main pattern display area 343 when the color transmitted by the base plate 100 is messy or the color of the base plate 100 itself is too thick.

[0048] In one embodiment, the material of the base lining layer 31 is configured as a light - colored or transparent UV - curable resin, the material of the adhesive layer 32 is configured as a UV - curable resin, and the material of the protective film 35 is configured as a UV - curable resin. The light - colored base lining layer 31 can cover the color of the base plate 100 while enhancing the color expressiveness of the metal reflective layer 33 and the pattern printing layer 34. The UV - curable resin can effectively reduce the time spent on processing the mobile phone case. After applying a layer of UV - curable resin, through the irradiation of an ultraviolet lamp, the UV - curable resin solidifies quickly to facilitate the next process. It should be noted that the UV - curable resin is only a general term for a category of materials, referring to materials that can cure monomers and oligomers through chain polymerization reactions under the action of ultraviolet light. Therefore, it can be understood that the molecular formula of the UV - curable resin used for the base lining layer 31 is different from that of the UV - curable resins used for the adhesive layer 32 and the protective film 35. That is, in the production process of the mobile phone case, at least two different UV - curable resins are selected.

[0049] The above is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present utility model.
