It should be noted that, the housing provided in the present application may be a housing (e.g., a battery cover) of an electronic device, or may be a housing of a non-electronic product. The electronic device may be a mobile phone, a tablet computer, a personal digital assistant (Personal Digital Assistant, PDA), an electronic book reader, a notebook computer, a vehicle-mounted computer, a set top box, a smart television, a wearable device, a navigator, a palm game machine, a household appliance, or the like. In this regard, the present application is not particularly limited.

The housing provided in the present application is described in exemplary fashion with reference to the accompanying drawings.

As shown in fig. 1, this embodiment of the application provides a casing, including transparent protective layer 1, light-transmitting layer 2 and shading color development layer 3 that stack gradually the setting, regard light-transmitting layer 2 as the skeleton of casing promptly, set up protective layer 1 and shading color development layer 3 respectively at the two sides that light-transmitting layer 2 deviate from each other.

The transparent protective layer 1 is used as an exposed layer of the shell and is arranged facing the external environment, has high hardness, and can prevent the external environment from wearing the light-transmitting layer 2 or the shading color-developing layer 3 in the shell, so that the appearance effect of the shell is maintained. On the other hand, the structure inside the housing (e.g., electronics in the electronic device within the electronic device enclosure) is protected from the external environment.

In one example, the transparent protective layer 1 may be an Ultraviolet (UV) varnish hardening layer, that is, UV varnish is sprayed on the light-transmitting layer 2 and then irradiated with a UV lamp so that the UV varnish is solidified to form a UV varnish hardening layer. The UV gloss oil hardened layer has the characteristics of scratch resistance, higher light transmittance and good glossiness, so that the shell has glass texture, and the aesthetic property of the shell is improved.

Alternatively, the transparent protective layer 1 may also be a layer of organic glass, for example PMMA.

The dye can be quinophthalone, which has high tinting strength and high heat resistance stability, and can ensure the stability of the appearance effect of the light-transmitting layer 2. For example, quinophthalone-based pigment yellow 138 has vivid strong green light and superior color rendering, and by mixing quinophthalone-based pigment yellow 138 into the first transparent base material, the light-transmitting layer 2 can exhibit a green and transparent appearance effect.

Alternatively, the dye may be a beryllium-ketone system, which is generally red or yellow in color. By mixing beryllium ketone system into PC, the light-transmitting layer 2 can exhibit a red or yellow and transparent appearance effect.

Alternatively, the dye may be an azo pigment, and the azo pigment may be pigment yellow 93 in green yellow, pigment yellow 95 in red yellow, pigment yellow 128 in green yellow, pigment red 144 in bluish blue, pigment red 166 in brilliant yellow red, pigment red 214 in blue, pigment red 242 in brilliant yellow scarlet, pigment red 262 in blue, or the like. Pigment red 242 is bright in color and excellent in color rendering, and pigment red 242 is taken as an example, pigment red 262 is mixed into the first transparent base material, so that the light-transmitting layer 2 can present a bright red and transparent appearance effect with yellow light, and is bright in color and high in aesthetic property.

Alternatively, the dye may be phthalocyanine, the color of which is normally bright green-blue, and by mixing phthalocyanine into the first transparent substrate, the light-transmitting layer 2 is enabled to exhibit an appearance effect with bright green-blue and transparent.

Alternatively, the dye may be a perylene comprising red pigment with a bright color: pigment red 149 and 179 which are bright red, pigment red 178 which is slightly yellow and dark, pigment violet 29 which is dark and purplish red, and the like, and perylene generally has excellent sun-proof, heat-resistant and solvent-resistant properties. Illustratively, taking pigment red 149 as an example, pigment red 149 is mixed into the first transparent substrate such that the light-transmitting layer 2 can exhibit an appearance effect with a bright red color and transparency.

Alternatively, the dye may be an isoindolone including pigment yellow 109 in green yellow, a very red yellow pigment: pigment yellow 110, pigment yellow 139 which is red yellow, and the like. Illustratively, taking pigment yellow 139 as an example, by mixing pigment yellow 139 into the first transparent substrate, the light-transmitting layer 2 can exhibit an appearance effect of yellow with red light and transparent.

Alternatively, the dye may be anthraquinone, which is generally yellow in color, bright in color, high in fixation rate and superior in color fastness, so that the light-transmitting layer 2 may exhibit a yellow and transparent appearance effect by mixing anthraquinone into the first transparent substrate.

Alternatively, the dye may be thioindigo, which is typically blue-red, so that the light-transmitting layer 2 may appear as an appearance effect with blue-red and transparent by mixing thioindigo into the first transparent substrate.

The above dyes are merely illustrative examples, and the material of the dyes is not particularly limited in the present application.

It should be noted that, in one embodiment, a dye may be uniformly mixed into the first transparent substrate, so that the light-transmitting layer 2 entirely assumes the corresponding color. It is also possible to mix the dye into a partial region of the first transparent substrate so that the partial region of the light-transmitting layer 2 assumes the corresponding color. In another embodiment, multiple dyes may be mixed into different areas of the first transparent substrate, so that the light-transmitting layer 2 can exhibit a more abundant glare effect. Illustratively, as shown in fig. 2, the light-transmitting layer 2 may be divided into two regions: a middle region 21 and an edge region 22, pigment yellow 110 is mixed in the PC of the middle region 21 so that the middle region 21 of the light-transmitting layer 2 is red-yellow; the thioindigo is mixed in the PC of the edge area 22, so that the edge area 22 of the light-transmitting layer 2 is blue-red, the whole light-transmitting layer 2 can show a richer colorful effect, and the attractiveness of the light-transmitting layer 2 is improved. Thus, the light-transmitting layer 2 provided by the application can show more, richer and more colorful appearance effects by selecting different dyes.

In one example, the light-transmitting layer 2 may be provided with a special glare effect by mixing pigment particles with the first transparent substrate. Such as a sparkle effect, a fluorescence effect, etc. Therefore, no extra flash sand layer with gorgeous effect particles such as flash sand is needed, the structure of the shell is simplified, and the development of lightening and thinning of the electronic equipment is facilitated.

The pigment particles may be mica-based pearlescent particles, for example, silver-white mica titanium series, interference-color mica titanium series, or colored mica titanium series. For example, silver titanium mica or interference color titanium mica may be incorporated into the first transparent substrate, and thus the light-transmitting layer 2 may exhibit an appearance effect with a pearlescent color.

Alternatively, the pigment particles may also be metal powders, such as aluminum powder, zinc powder, lead powder, gold powder, zinc aluminum powder, stainless steel powder, and the like. Taking aluminum powder as an example, mixing aluminum powder into the first transparent substrate can make the light-transmitting layer 2 exhibit an appearance effect with yellow sparkle.

Alternatively, the pigment particles may be surface metal oxide particles.

The above pigment particles are merely illustrative examples, and the material of the pigment particles is not particularly limited in the present application.

It should be noted that, in one embodiment, a pigment particle may be uniformly mixed into the first transparent substrate, so that the light-transmitting layer 2 as a whole exhibits a corresponding appearance effect. It is also possible to mix pigment particles into a partial region of the first transparent substrate so that the partial region of the light-transmitting layer 2 exhibits a corresponding appearance effect. In another embodiment, a plurality of pigment particles may be mixed into the first transparent substrate, so that the light-transmitting layer 2 can exhibit a more abundant glare effect. In this regard, the present application is not particularly limited.

In another example, the first filler may include both dye and pigment particles such that the light transmissive layer 2 itself may have a more gorgeous, richer, and colorful effect, for example, mixing titanium silver mica and thioindigo into the first transparent substrate such that the light transmissive layer 2 appears as a pearlescent, blue-red appearance. Therefore, the red color layer and the pearlescent effect layer are not required to be additionally added, the shell structure is simplified, the appearance effect which can be presented by the shell is more gorgeous and rich, and the aesthetic property of the shell is improved.

In summary, through selecting different dyes and pigment particles, the light-transmitting layer 2 can have flexible and rich colorful effects, and additional color layers and flash sand layers do not need to be overlapped, so that the structure of the shell is simplified, the preparation process and the process cost of the shell are reduced, and the light and thin design of the shell is facilitated.

In one example, the light-transmitting layer 2 provided in the embodiment of the present application may further include an improving agent mixed in the first transparent substrate, which may further improve the appearance effect of the light-transmitting layer 2 and ensure the stability of the light-transmitting layer 2.

Illustratively, the improver may include one or more of an antioxidant, a dispersant, and a stabilizer.

Wherein, the antioxidant can avoid the problem of oxidative discoloration after the dye and pigment particles contact with air, and the material characteristics of the dye and pigment particles can be ensured by adding the antioxidant, thereby improving the stability of the appearance effect presented by the light-transmitting layer 2.

Alternatively, the antioxidant may comprise one or more of a phenolic antioxidant, a phosphite antioxidant, and a metal ion scavenger.

The dispersing agent can enable the dye and pigment particles to be uniformly distributed in the first transparent base material, so that the appearance effect presented by the light-transmitting layer 2 is ensured to be uniformly distributed, and the overall appearance of the shell is ensured to be attractive.

Alternatively, the dispersant may comprise one or more of a hydrophilic acrylic copolymer, a polyoxyethylene-based active agent.

The stabilizer can absorb ultraviolet light, avoids the problem that dye and pigment particles change color under the action of the ultraviolet light, ensures the stability of the dye and pigment particles, and improves the stability of the appearance effect presented by the light-transmitting layer. The stabilizer may be a UV absorber, for example, may include one or more of UV-531, salicylate-based stabilizer, benzophenone-based stabilizer, benzotriazole-based stabilizer, substituted acrylonitrile-based stabilizer, triazine-based stabilizer, and hindered amine-based stabilizer.

In one example, the light-transmitting layer 2 provided in the embodiment of the present application may be prepared by injection molding, and the surface of the base material prepared by injection molding is smooth and has no scratch, and the production efficiency is high. Injection molding refers to injecting a completely molten plastic material into a mold cavity under high pressure at a certain temperature, and obtaining an injection molded base material after cooling and solidifying.

By taking the first transparent substrate as PC as an example, PC has higher transparency and free dyeing property, so that after the first filler is mixed with PC, the first transparent substrate can show the appearance effect corresponding to the characteristic of the first filler, and the stability of the appearance effect shown by the first transparent substrate is ensured. The injection molding process of the light-transmitting layer 2 in the embodiment of the application may be:

the first step: the forced air drying oven was set to 100 ℃ (degrees celsius) and the PC was then placed into dry for more than 4 hours, ensuring adequate drying of the PC.

And a second step of: the dye, pigment particles and PC were placed in a high speed mixer for mixing according to preset appearance requirements to mix the dye, filler into the PC. And pouring the stirred raw materials into a double-screw extruder, setting the temperature of the double-screw extruder to be 220-300 ℃, and shearing, extruding, cooling, blow-drying and granulating the stirred raw materials to form plastic particles. It is worth noting that the plastic particles prepared and formed herein have a gorgeous and rich appearance effect and can be called as aesthetic plastic.

And a third step of: the plastic particles are filled into a mold, and the light-transmitting layer 2 which can meet the preset appearance requirement is obtained through the treatment of pressure maintaining, cooling, demolding and other treatment processes.

It will be appreciated that the types of the dye and pigment particles, and the addition ratio may be selected according to the predetermined appearance requirements so that the finally prepared light-transmitting layer 2 can meet the predetermined appearance requirements. That is, by adjusting the kinds and proportions of the dye and pigment particles, the appearance effect exhibited by the light-transmitting layer 2 can be flexibly set. Illustratively, each raw material may include, in parts by weight, 90 to 99 parts by weight of dry PC, 0.1 to 0.5 part by weight of the dye, 0.2 to 5 parts by weight of the pigment particles, 0.1 to 0.6 part by weight of an antioxidant, 0.05 to 1 part by weight of a dispersant, and 0.1 to 1 part by weight of a stabilizer during addition.

The light-shielding color-developing layer 3 provided in the embodiment of the present application has a light-shielding effect, and is generally disposed facing the inside of the electronic device or the non-electronic product, so as to shield the structure in the inside of the electronic device or the non-electronic product. In this application embodiment, shading developing layer 3 can include at least one colour region, so, combines light-transmitting layer 2 with the shading developing layer 3 that presents at least one colour for the shell structure has the outward appearance effect that the layering sense is richer, gorgeous more, further improves the aesthetic property of casing.

In one example, as shown in fig. 3, the light-shielding color-developing layer 3 provided in the embodiment of the present application may include a transparent film 31 and at least one color layer 32, where the transparent film 31 is disposed on a surface of the transparent film 2 facing away from the transparent protective layer 1, and the color layer 32 is disposed on a surface of the transparent film 31 facing away from the transparent layer 2.

The transparent film 31 may be a colorless transparent film, and at least one color layer 32 is disposed on a surface of the transparent film 31 facing away from the light-transmitting layer 2, so that the at least one color layer 32 may form at least one color region on the transparent film 31. For example, the at least one color region may be presented as a preset graphic or text, a solid color effect, a tile effect, a gradient color effect, etc., which is not particularly limited in this application.

Alternatively, the transparent film 31 may be a polyethylene terephthalate (Polyethylene terephthalate, PET) film, and the PET film itself is a colorless transparent and glossy film, which can be provided with a rich appearance effect by priming patterns, characters or colors on the side of the PET film facing away from the light-transmitting layer 2. And the PET membrane has higher hardness and toughness, can play a protection role on the light-transmitting layer 2 to a certain extent, and avoid damage to the light-transmitting layer 2 of the internal structure of electronic equipment or non-electronic products.

The color layer 32 may be disposed on the surface of the transparent film 31 by transfer printing, film plating, coating, or the like. It is understood that the transfer means to apply an image having color saturation to the surface of the transparent film 31, the painting means to apply a dye having color saturation to the surface of the transparent film 31, and the plating means to plate a film having color on the surface of the transparent film 31.

To reduce the manufacturing process, in one example, the light-shielding color-developing layer 3 may include at least one color layer 32, and the color layer 32 may be directly formed on a side of the light-transmitting layer 2 facing away from the transparent protective layer 1. For example, at least one color area can be directly formed on one surface of the light-transmitting layer 2, which is away from the transparent protective layer 1, by means of transfer printing, film plating, coating and the like, so that the structure of the shell is further simplified, and the complexity and the manufacturing cost of the manufacturing process are reduced.

The light-transmitting layer 2 provided by the embodiment of the application is provided with dye and pigment particles, so that the light-transmitting layer is flexible and rich in colorful effect, color display is not required to be realized by superposing additional color layers, the structure of the shell is simplified, the preparation process and the process cost of the shell are reduced, and the light and thin design of the shell is facilitated. And still with the printing opacity layer 2 with present the shading color development layer 3 that has at least one colour in the casing that this application embodiment provided and make up for the casing structure has the richer outward appearance effect of layering sense, further improves the aesthetic property of casing. Therefore, the housing provided by the embodiment of the application can simplify the housing structure under the condition of improving the appearance effect.

In one example, as shown in fig. 4, the case provided in the embodiment of the present application may further include a texture layer 4 disposed between the transparent protective layer 1 and the light-transmitting layer 2, and the texture layer 4 itself may be provided with a transparent structure of a texture pattern. By adding the texture layer 4, the appearance effect presented by the shell has a certain layering sense and a certain stereoscopic sense, and the attractiveness of the shell is improved.

Alternatively, the texture layer 4 may comprise a second transparent substrate, which may be a PC or other transparent plastic.

Alternatively, the texture layer 4 may include a second transparent substrate and a second filler mixed in the second transparent substrate, where the second filler may include one or more of a dye and pigment particles, and after the second filler is mixed with the second transparent substrate, the texture layer 4 itself has a flexibly rich colorful effect. Through the mutual superposition of the texture layer 4 and the light-transmitting layer 2, the shell finally presents a more layered and richer appearance effect. It should be noted that the materials of the dye and pigment particles in the second filler may be the same as those of the dye and pigment particles in the first filler, and thus, the description thereof will not be repeated.

In one example, the texture layer 4 and the light transmissive layer 2 are separate structures, e.g., the separate texture layer 4 and light transmissive layer 2 are press fit. In this example, the materials of the second transparent substrate and the second transparent substrate may be the same or different, and the materials of the first filler and the second filler may be the same or different. For example, the first filler and the second filler are different dyes and/or pigment particles, so that the shell formed by superposing the texture layer 4 and the light-transmitting layer 2 can have richer, more layering and colorful appearance effects. For example, the light-transmitting layer 2 may be a colored light-transmitting layer with fluorescent characteristics, and the texture layer 4 may be a colored light-transmitting layer provided with a gold flash sheet, and after the two layers are stacked, the colors are stacked and the characteristics are stacked, so that the shell can finally present the appearance with the fluorescent characteristics and the gold flash sheet and the stacked color effect with layering.

In another example, to reduce the manufacturing process, the texture layer 4 and the light-transmitting layer 2 may be an integrated structure, where the first transparent substrate and the second transparent substrate are the same and the first filler and the second filler are the same.

Alternatively, the texture layer 4 and the light-transmitting layer 2 may be an injection-molded integrated structure, so that the texture layer 4 does not need to be separately prepared, and the manufacturing process is reduced.

In one example, the surface of the light-transmitting layer 2 facing the transparent protective layer 1 may be directly textured by an embossing process, for example, embossing a metal on the light-transmitting layer 2 by a mechanical device, so that the surface of the light-transmitting layer 2 may exhibit a textured structure with protrusions and depressions. Therefore, the structure of the shell is simplified, and the preparation process and the process cost of the shell are reduced without additionally superposing the texture layer 4.

To sum up, the casing that this application embodiment provided, the light-transmitting layer 2 itself is from taking nimble abundant colorful effect, does not need to make the casing realize color display through the extra colour layer of stack, has simplified the casing structure.
