The examples, where specific techniques or conditions are not indicated, are to be construed according to the techniques or conditions described in the literature in the art or according to the product specifications.

In one aspect of the present application, a housing assembly is provided. According to an embodiment of the present application, referring to fig. 1, the housing assembly 100 has a bright zone S, and the housing assembly 100 includes: a glass body 10; the color layer 20 is arranged on one surface of the glass body 10, and the orthographic projection of the color layer 20 on the glass body 10 is not overlapped with the orthographic projection of the bright area S on the glass body 10; the UV texture layer 30 is arranged on one side, away from the glass body 10, of the color layer 20, and the orthographic projection of the UV texture layer 30 on the glass body 10 covers the orthographic projection of the bright area S on the glass body 10; coating 40, coating 40 sets up on the surface of UV texture layer 30 far away from glass body 10. From this, because do not set up colour layer 20 (being the bright zone for the colorless area) in bright zone S, so, the light shines and shines the obvious bright effect that can be obtained through coating film layer 40 reflection again after UV texture layer 30 in bright zone S, and do not need equipment such as lamp area to provide light, this application only needs the coating film layer will pass the light reflection on UV texture layer 30 and can obtain bright glittering effect, so the housing assembly of this application not only has unique outward appearance effect, and housing assembly' S simple structure, also be convenient for make and industrialization volume production on the technology.

The specific material, size and thickness of the glass body 10 have no special requirement, as long as the use requirement of the housing assembly can be met. In some embodiments, the glass body is made of corning GG5 material, and has a thickness of 0.5-0.8 mm (e.g., 0.6mm, 0.7mm, etc.), and the size is determined according to the size of the electronic device using the housing assembly.

According to an embodiment of the present application, referring to fig. 2, the housing assembly 100 further includes: a first membrane 50, wherein the first membrane 50 is arranged on the surface of the color layer 20 close to the glass body 10; a first glue layer 51, the first glue layer 51 being disposed between the glass body 10 and the first membrane 50. From this, the setting of first diaphragm, can be in the preparation technology of casing subassembly, in advance with structures preparation such as colour layer 20, UV texture layer 30, coating film layer 40 on a surface of first diaphragm, later laminate another surface and the glass body of first diaphragm at rethread first glue film, and then can obtain the good, the casing subassembly of being convenient for preparation of laminating effect, moreover do not have the restriction requirement to the appearance structure of casing subassembly (or glass body), can be in order to make above-mentioned appearance effect on the glass body of 2D, 2.5D or 3D structure. Especially, when the 3D structure housing assembly is manufactured, since it is difficult to directly manufacture the structures such as the color layer, the texture layer, and the film coating layer with better quality at the bending position of the glass body, the process of directly manufacturing the structures such as the color layer on the glass body with the 3D structure can be avoided by manufacturing the above structures on the diaphragm and then attaching the glass body.

The thicknesses of the first membrane and the first adhesive layer are not limited, and the first membrane and the first adhesive layer can be flexibly selected by a person skilled in the art according to actual conditions. In some embodiments, the first membrane has a thickness of 23 microns and the first glue layer has a thickness of 17 microns.

Further, referring to fig. 3, the housing assembly 100 further includes: a second membrane 60, wherein the second membrane 60 is arranged on the surface of the UV texture layer 30 close to the glass body 10; and the second adhesive layer 61, wherein the second adhesive layer 61 is arranged between the second film 50 and the color layer 20. Thus, in some embodiments (the housing assembly does not include the first film sheet), the color layer 20 and the UV texture layer 30 may be respectively formed on two surfaces of the second film sheet when the housing assembly is manufactured, and then the surface of the color layer 20 is attached to the glass body 10 through the second adhesive layer 61; in other embodiments (including the first film 50), the color layer 20 is formed on one surface of the first film 50, the UV texture layer 30 and the film coating layer are sequentially formed on one surface of the second film 60, the other surface of the second film 60 is bonded to the color layer 20 through the second adhesive layer 62, and then the other surface of the first film 50 is bonded to the glass body 10 through the first adhesive layer 51. The two manufacturing methods can realize good fit between the appearance membrane and the glass body, and have no limit requirement on the appearance structure of the shell assembly (or the glass body), namely the appearance effect can be manufactured on the glass body with a 2D, 2.5D or 3D structure. Especially, when the 3D structure housing assembly is manufactured, since it is difficult to directly manufacture the structures such as the color layer, the UV texture layer, and the film coating layer with better quality at the bending position of the glass body, the above-mentioned process of directly manufacturing the structures such as the color layer on the 3D structure glass body can be avoided by manufacturing the structures such as the color layer and the UV texture layer on the diaphragm and then attaching the structures to the glass body. Moreover, compared with the case of using one membrane (the first membrane 50 or the second membrane 60) for two membranes (the first membrane 50 and the second membrane 60), the adhesion between different layer structures is better, and especially, the adhesion between the color layer 20 and the first membrane 50 and the adhesion between the UV texture layer 30 and the second membrane 60 are better than the adhesion between the color layer 20 and the UV texture layer 30 and better than the adhesion between the color layer 20 and the glass body 10, so that the structural stability and reliability between different layer structures in the housing assembly 100 can be greatly improved by using two membranes; and the fullness and the fineness of the whole color of the shell assembly 100 can be improved through the attachment of the two layers of membranes.

The laminating process with the glass body has no special requirements, and technicians in the field can flexibly select the laminating process according to actual conditions, for example, prepared appearance membranes (a first membrane and a second membrane which are provided with a color layer and a texture layer) are firstly pasted to a positioning membrane, a laminating machine is used for laminating the membranes to the inner surface of the glass body, and then bubbles between the appearance membranes and the glass body are removed through a defoaming machine.

The thicknesses of the second membrane and the second adhesive layer are not limited, and the second membrane and the second adhesive layer can be selected flexibly by a person skilled in the art according to actual conditions. In some embodiments, the thickness of the second membrane is 50 microns and the thickness of the second glue layer is 30 microns.

The materials of the first membrane 50 and the second membrane 60 have no special requirement, and the transparent materials are only required to meet the use requirement of the shell assembly. In some embodiments, the material of the first and

second membranes

50, 60 is at least one of PET (polyethylene terephthalate), PC (polycarbonate), and TPU (thermoplastic polyurethane elastomer rubber).

The specific materials of the first adhesive layer 51 and the second adhesive layer 61 also have no special requirements, and those skilled in the art can flexibly select the specific materials according to actual situations, for example, the specific materials of the first adhesive layer 51 and the second adhesive layer 61 may be OCA optical adhesive, so that the light transmittance is better, and the appearance performance of the color layer and the texture layer is not affected.

It should be noted that, the bright area S is not provided with a color layer, that is, the bright area S corresponding to the color layer 20 is in a hollow state, and the hollow hole may be filled with vacuum or air, or may be filled with colorless transparent ink or optical glue, and those skilled in the art may select the color layer flexibly according to actual needs.

According to an embodiment of the present application, referring to fig. 4 and 5, the color layer 20 includes a first gradient area 21 and a non-gradient area 22 (the first gradient area 21 is a color layer area with a changed color, and the non-gradient area 22 is a color layer area with a non-changed color), the first gradient area 21 is disposed adjacent to the bright area S in the horizontal direction, and the first gradient area 21 is located on at least one side of the bright area S. From this, one side in bright zone S has bright colour gradual change region together, connect through the gradual change colour between at least one side in bright zone (being no colour region) and the colour layer (being even colour region) of non-gradual change district 22 like this, so can make casing assembly ' S outward appearance color have obvious stereovision, the reflection of light effect on coating film layer combines again, make casing assembly ' S colour gradual change district ' S luminance better, the gradual change of colour and the combination on coating film layer, can make casing assembly present optics and the blend of colour gradual change, make the casing have obvious stereovision and gorgeous effect more.

Wherein the color of the first gradual change region 21 is gradually deepened in a horizontal direction away from the bright region S. Thereby, an abrupt effect between the colorless of the bright regions S and the dark color of the non-gradation regions 22 can be avoided. In some embodiments, the color of the color layer of the non-gradation region 22 is dark blue, and the color of the first gradation region 21 gradually changes from light blue to dark blue.

Further, referring to fig. 6, the color layer 20 further includes a second transition region 23, and an orthographic projection of the second transition region 23 on the glass body 10 is located at an edge region of the glass body 10 (only one edge region is shown in fig. 6). Therefore, different color changing effects can be shown at the edge of the shell assembly, and the second gradual change area 23 can show a bright and gorgeous gradual change color effect in the appearance of the shell assembly by combining the reflection effect of the coating layer.

Wherein the color of the second gradation region 23 becomes gradually lighter in a direction close to the side end face of the color layer 20 (i.e., the side end face of the peripheral edge of the color layer) (i.e., in a direction in the horizontal direction and away from the first gradation region 21). Therefore, the color between the non-gradation region 22 and the second gradation region 21 can be smoothly and gently changed, thereby preventing the change of large span between different colors from causing a person to feel very abrupt.

Referring to fig. 7 (taking the bright area as a strip in fig. 7 as an example), the housing assembly 100 is an integrated structure of the battery rear cover 110 and the middle frame 120, and the edge area is located in the middle frame 120, that is, the second gradual change area 23 is located at the middle frame 120. Therefore, the gradual change colors of the second gradual change area are combined with the radian design of the 3D glass body, so that the middle frame of the shell has better optical dynamic effect, and the colors are more gorgeous, so that the peripheral colors of the shell assembly are more gorgeous and colorful and glittering and translucent.

In addition, the specific positions of the first transition area 21 and the bright area S are not particularly required, and those skilled in the art can flexibly design the first transition area and the bright area S according to practical situations, for example, the first transition area and the bright area S may be the middle position in the rear cover 110 of the battery in fig. 7.

In some embodiments, the bright areas S are in the form of stripes (as shown in FIG. 7); in other embodiments, referring to fig. 8 (in fig. 8, the first gradient area 21 is disposed on the side of the annular bright area S close to the middle frame 120 as an example), the shape of the bright area S is annular, and referring to fig. 9 (only the annular bright area S, the first gradient area 21 and a part of the non-gradient area 22 are shown in fig. 9), wherein, fig. 1 to 4 can be referred to in a cross-sectional view along AA 'in fig. 8, and fig. 6 can be referred to in a cross-sectional view along BB' in fig. 8, so that the outer surface of the housing assembly has a bright annular runway, and the outer side of the annular runway has a bright gradient color surrounding the annular runway, so that the gradient color is gradually changed from colorless to black, and is integrated with the color of the non-gradient area.

Referring to fig. 8, the width D of the bright area is 1 to 3 mm, such as 1 mm, 1.5 mm, 2 mm, 2.5 mm, or 3 mm. Therefore, the bright area has obvious bright effect.

According to embodiments of the present application, the color layer is prepared by offset printing, thermal ribbon transfer, or inkjet printing. When offset printing or color ribbon transfer printing is adopted, a color layer with finer colors can be obtained, and the fineness of the appearance color of the shell assembly is further improved. The specific process steps and conditions of the method have no special requirements, and the skilled person can flexibly design and select the method according to the actual situation.

In some embodiments, the color layer is prepared by a four-color offset printing process, and four groups of offset printing wheels used in conventional offset printing can be increased into six groups of offset printing wheels during preparation, so that the fineness and the resolution of the prepared color layer can be greatly improved (the resolution can reach 2400 dpi). Taking the preparation of the blue-black color layer 20 as an example, when the non-gradation region 22 is prepared, the black non-gradation region is obtained by offset printing, when the first gradation region 21 and the second gradation region 23 are prepared, the mixture ratio of the four raw material color pastes is adjusted, so that the concentration of the blue color ribbon in the mixed raw material color paste is gradually reduced in the predetermined direction (i.e., the concentration of the blue color ribbon in the first gradation region 21 is gradually reduced in the horizontal direction away from the direction of the light brightness S, and the concentration of the blue color ribbon in the second gradation region 23 is gradually reduced in the direction close to the side end face of the color layer), thereby realizing the gradual change from light blue to black (the color of the gradation region is increasingly darker and darker), and the darker the lower the concentration of the blue color ribbon, the lower the light transmittance, the less light reflected by the film coating layer, and the lower visual brightness; the lighter the color in the gradual change area is, the higher the concentration of the blue color band is, the higher the light transmittance is and the higher the permeability is, the more light rays are reflected by the coating layer, and the higher the visual brightness is.

The change rate of the blue color band density in the first gradation area 21 and the second gradation area 23 has no special requirement, and those skilled in the art can flexibly set the change rate according to the actual conditions such as the width of the first gradation area 21 and the second gradation area 23. In some embodiments, the width of the first fade area 21 is 3 mm, and the gradation curve of the blue band intensity thereof is referred to fig. 10 (where the abscissa distance S1 refers to the distance between a certain point in the first fade area 21 and the bright area); in other embodiments, the width of the second fade area 23 is 6mm, and the gradation curve of the blue band darkness thereof is referred to fig. 11 (where the abscissa distance S2 refers to the distance between a certain point in the second fade area 23 and the side end surface of the color layer).

The widths of the first transition region and the second transition region have no special requirement, and those skilled in the art can flexibly select and design the transition region according to the actual situation, and the requirements are not limited herein. In addition, the thickness of the color layer has no special requirement, and a person skilled in the art can flexibly select the thickness according to the specific process for preparing the color layer, for example, when offset printing is adopted to prepare the color layer, the thickness of the color layer can be 2.0-3.0 micrometers.

According to an embodiment of the present invention, referring to fig. 12 and 13, the UV texture layer 30 includes a uniform thickness texture layer 31 and a non-uniform thickness texture layer 32, wherein an orthographic projection of the non-uniform thickness texture layer 32 on the glass body 10 overlaps with an orthographic projection of the first transition region 21 and/or the second transition region 23 on the glass body 10. Therefore, when the visual angle is changed, the arrangement of the texture layers with different thicknesses (namely different thicknesses) can realize the visual effect from dark to bright through the height difference of the textures, the high contrast of light and shade can well set off the light-emitting effect of the first gradient area and/or the second gradient area, so that the optical gradient and the color gradient are blended together, the unique effect that the appearance of the shell assembly changes along with light is achieved, namely, the gradient areas can present different brightness at different angles, and the appearance of the shell assembly has more layering; moreover, for the second gradual change region 23 of the shell assembly with the 3D structure, the optical gradual change is combined with the design of the radian of the 3D curved glass, so that the middle frame is more optical dynamic, and the middle frame of the shell assembly is more glittering and translucent.

Referring to fig. 14, the texture layer 32 with different thicknesses includes a plurality of sub-texture layers 321 with different thicknesses and arranged in a splicing manner, and the plurality of sub-texture layers 321 are triangular prisms or pyramids (the cross section is triangular). Therefore, when different viewing angles are changed, the light and shade contrast effects of different degrees can be back-lined by the texture layers with different thicknesses by combining the reflection effect of the coating layer. The triangular prism or the pyramid can be any one of an isosceles triangle, an equilateral triangle and an irregular triangle, and the person skilled in the art can flexibly select the triangular prism or the pyramid according to the actual situation.

Further, as shown in FIG. 14, in the plurality of sub-texture layers 321, the ratio of the minimum thickness H2 of the sub-texture layer 321 to the maximum thickness H1 of the sub-texture layer 321 is 1/3 to 2/3. Therefore, the contrast degree of the light and shade effect of the color gradient area (comprising the first gradient area 21 and the second gradient area 23) can be better improved, and the appearance effect of the gradient area is further improved; if the ratio is less than 1/3, the contrast effect of the light and shade reverse-lined by the texture layer with different thickness is relatively poor; if the ratio is greater than 2/3, the structural stability of the sub-texture layer with the higher thickness in the non-uniform texture layer is not facilitated. The size of the width d of each sub-texture layer 321 and the size relationship of the widths d of different sub-texture layers 321 have no special requirement, and those skilled in the art can flexibly select the width d according to the actual situation, which is not limited herein.

The thickness of the equal-thickness texture layer 31 is not limited, and those skilled in the art can flexibly design the thickness of the UV texture layer according to the thickness requirement of the conventional shell assembly. In some embodiments, the thickness of the iso-thick texture layer 31 may be between H1 and H2. Therefore, the overall structural stability of the UV texture layer is convenient to guarantee. In some embodiments, the constant thickness textured layer has a thickness of 12 to 18 microns (e.g., 12 microns, 14 microns, 15 microns, 18 microns).

According to the embodiment of the application, the coating layer 40 includes the indium layer, and the reflectivity of the indium layer can reach 50% -80%, so that light passing through the UV texture layer can be effectively reflected, so as to improve the brightness of the housing assembly, and particularly improve the brightness of the first gradual change region 21 and/or the second gradual change region 23 and the brightness region S.

Further, the coating layer 40 further includes at least one of silicon dioxide and titanium pentoxide. In some embodiments, the coating layer 40 includes a first silicon dioxide (contacting with the UV texture layer 30, priming transition, and enhancing adhesion of the coating layer), a first titanium oxide, a second silicon dioxide, an indium (with excellent reflection effect, larger thickness, stronger reflection effect, and larger brightness), a third silicon dioxide, and a second titanium oxide, which are stacked in sequence, wherein the second silicon dioxide and the third silicon dioxide disposed adjacent to the indium layer can protect the indium layer to prevent the indium layer from conducting electricity, and simultaneously prevent the indium layer from being oxidized to reduce reflection effect.

In the above embodiment, the thickness of the indium layer is 10 to 20 nm, the thickness of the first silicon dioxide is 8 to 12 nm, the thickness of the first titanium oxide is 7 to 17 nm, the thickness of the second silicon dioxide is 10 to 20 nm, the thickness of the third silicon dioxide is 20 to 30 nm, and the thickness of the second titanium oxide is 5 to 9 nm.

Thus, light leakage from the case assembly 100 can be prevented.

The color of the bottom ink layer 70 is not limited, and may be black or white, for example.

In addition, the under-cap ink layer 70 may include a plurality of sub-under-cap layers stacked. In some embodiments, the cover bottom ink layer comprises four sub cover bottom layers, and the thickness of each sub cover bottom layer is 2-8 microns. Furthermore, a gloss oil layer with the thickness of 5-9 microns is arranged between any two layers of the four sub-cover bottom layers, so that the adhesive force and the binding force between the multiple sub-cover bottom layers can be improved.
