Detailed Description

Embodiments of the present application will now be described more fully hereinafter with reference to the accompanying drawings, in which it is shown, however, in which some, but not all embodiments of the application are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present application without departing from the spirit or scope of the application. Accordingly, it is intended that the present application covers the modifications and variations of this application provided they come within the scope of the appended claims (the claims) and their equivalents. The embodiments provided by the embodiments of the present application may be combined with each other without contradiction.

As described in the background art, the electronic device needs to use a housing to encapsulate and protect the electronic component. The shells of conventional electronic equipment, such as a mobile phone rear shell, a tablet personal computer rear shell, a wearable equipment rear shell and the like, are all of single-color thickness, and although richer appearance patterns can be realized by adding a planar coating, only a two-dimensional planar pattern structure can be realized, and the appearance pattern is single.

In view of the foregoing, the present application provides an electronic device and a method for manufacturing a housing thereof, where the housing of the electronic device is capable of presenting a first stereoscopic texture pattern having a visual effect including a target color, and the first stereoscopic texture pattern at least includes: a first layer of texture and a second layer of texture, the first layer of texture exhibiting the target color having a different effect than the second layer of texture exhibiting the target color. The shell of the electronic equipment can display the first stereoscopic texture pattern based on the first layer texture and the second layer texture, and the diversity of appearance patterns is increased relative to the conventional electronic equipment shell which can only display a two-dimensional plane pattern structure.

In order that the above-recited objects, features and advantages of the present application will become more readily apparent, a more particular description of the application will be rendered by reference to the appended drawings and appended detailed description.

Referring to fig. 1 and 2, fig. 1 is a sectional view of a housing of an electronic device according to an embodiment of the present application, and fig. 2 is a partially enlarged top view of the housing of the electronic device shown in fig. 1, where the electronic device includes a housing 11, and the housing 11 is at least used for covering a portion of a receiving space of the electronic device.

Wherein the shell 11 presents a first stereoscopic texture pattern 12 whose visual effect comprises a target color, the first stereoscopic texture pattern 12 comprising at least: a first layer texture 121 and a second layer texture 122, the first layer texture 121 exhibiting a target color differently from the second layer texture 122 exhibiting the target color.

The first stereoscopic grain pattern 12 includes at least two layers of grains having different depths inside the case 11 in the thickness direction of the case 11, so that the first stereoscopic grain pattern 12 can exhibit a three-dimensional pattern variation of the height and the relief inside the case 11.

It should be noted that, for convenience of illustration, the first layer texture 121 is illustrated in fig. 2 as a triangle, the second layer texture 122 is illustrated as a rectangle with a dotted line, and the graphic structures of the first layer texture 121 and the second layer texture 122 may be defined based on requirements, which is not limited by the embodiment of the present application. The first layer texture 121 and the second layer texture 122 are different in depth inside the case 11 in the thickness direction of the case 11, so that the first stereoscopic texture pattern 12 can exhibit a three-dimensional pattern variation of height and undulation inside the case 11.

Optionally, the electronic device may be a mobile phone, a tablet computer, a wearable device, or the like. The housing 11 may be a body back shell of the electronic device. The electronic equipment is provided with a containing space, and the containing space is used for containing electronic components such as a circuit main board, a display screen, a power supply and the like. The housing 11 covers at least a portion of the accommodating space to encapsulate and protect electronic components of the electronic device. Taking a mobile phone as an example, the housing 11 may be a rear housing of the mobile phone, and may form a closed accommodating space with a display screen of the mobile phone, for accommodating electronic components such as a mobile phone motherboard and a battery.

In some implementations of the present embodiments, the housing 11 includes: a target layer for forming at least a first layer texture 121 and a second layer texture 122, the first layer texture 121 exhibiting a target color that is different from the second layer texture 122 exhibiting a target color. Wherein the target layer may be prepared by selecting an adapted material, and the first stereoscopic texture pattern 12 is presented based on the texture pattern of the material after curing and shaping itself, so that the housing 11 has the desired first layer texture 121 and second layer texture 122.

Referring to fig. 3, fig. 3 is a cut-away view of another electronic device housing provided in an embodiment of the present application, where a housing 11 of the electronic device includes: the target layer 111, the target layer 111 is used for forming at least a first layer texture 121 and a second layer texture 122, and the effect that the first layer texture 121 presents a target color is different from that of the second layer texture 122.

Wherein the thickness of the target layer 111 is not more than 0.2mm to reduce the thickness of the case 11. As shown below, the target layer 111 may be a film of acetic acid material, and may realize a rich three-dimensional texture effect of the case 11 through a texture pattern formed by curing the acetic acid material itself.

As shown in fig. 3, the housing 11 further includes: the optical layer 112, the optical layer 112 is used for changing the gloss subregion in the first texture region formed by the first layer texture 121 and the gloss subregion in the second texture region formed by the second layer texture 122 under different incident angles of incident light.

Referring to fig. 4 and 5, fig. 4 is an appearance effect diagram of an optical layer under a light incident angle provided by an embodiment of the present application, and fig. 5 is an appearance effect diagram of an optical layer under another light incident angle provided by an embodiment of the present application, as can be seen from fig. 4 and 5, the same optical layer provided by the embodiment of the present application can achieve different appearance pattern effects under different light incident angles.

The texture interface of the first layer texture 121 within the housing 11 is different from the texture interface of the second layer texture 122 within the housing 11, so that the first layer texture 121 is capable of forming a first texture region within the housing 11 based on the corresponding texture interface and the second layer texture 122 is capable of forming a second texture region within the housing 11 based on the corresponding texture interface. The optical layer 112 can adjust the light transmitted in the housing 11, and when the incident light has different incident angles, the gloss subregion in the first texture region formed by the first layer texture 121 and the gloss subregion in the second texture region formed by the second layer texture 122 can have different appearance effects. Wherein, the different appearance effects include different colors and/or different brightness of the interface patterns, so as to improve the diversity of the appearance patterns of the shell 11.

In one implementation of the embodiment of the present application, the target layer 111 includes at least: a first material for forming a first stereoscopic texture pattern 12; and a second material for improving the thermoplastic properties of the target layer and/or for imparting a set color to the target layer. Based on the first material's own properties, a three-dimensional texture pattern can be created after curing.

The first material may be an acetate material, such as acetate resin. The acetic acid material can form multi-layer texture patterns after curing and forming, so that the target layer 111 has the superposition appearance effect of multi-layer textures and target colors.

Optionally, the second material comprises: a plasticizer for improving the thermoplasticity of the target layer; a toner for imparting a set color to the target layer; the mass ratio of the plasticizer and the mass ratio of the toner are not more than 20 percent. Plasticizers include, but are not limited to, citric acid. The toner includes, but is not limited to, pearlescent and/or metallic powder.

When the first material is an acetic acid material, the mass ratio of the plasticizer and the mass ratio of the toner are set to be not more than 20%, so that the content of the acetic acid material in the target layer 111 is moderate, the three-dimensional texture effect can be better realized through the acetic acid material, and the thermoplasticity and the color appearance of the shell 11 can be better improved through the second material.

The acetic acid material is easy to shrink and deform when meeting high temperature, so that the shell is distorted and deformed, and the toughness of the target layer 111 can be increased by adjusting the mass ratio of the plasticizer, so that the hot press forming and the expansion of the shell 11 are facilitated. The mass ratio of the plasticizer may be set to not more than 10%, for example, may be 2% or 5%.

The problem of the disappearance of the texture layer in the target layer 111 due to the yellowing problem of the acetic acid material can be improved by adjusting the mass ratio of the toner. Alternatively, the mass ratio of the toner is set to be not more than 20%, so that the problem that the texture layer in the target layer 11 disappears due to the yellowing problem of the acetic acid material can be better improved.

The toner is mixed in the acetic acid material so that the target layer 111 has a moderate light transmittance. But also can be doped into the acetate fiber, even if the acetate fiber turns yellow, the color of the texture layer can be maintained based on the toner in the fiber, and the disappearance of the texture can be avoided.

Referring to fig. 6, fig. 6 is a sectional view of a housing of another electronic device according to an embodiment of the present application, and on the basis of the manner shown in fig. 3, the housing 11 shown in fig. 6 further includes: a base material layer 113, wherein the base material layer 113, the target layer 111, and the optical layer 112 are sequentially laminated and fixed in a first direction F1; the first direction F1 is a direction in which the base material layer 113 points toward the target layer 111.

In the housing 11, the substrate layer 113 is used as a carrier plate for supporting and carrying other film layers in the housing 11. Alternatively, the substrate layer 113 is a light-transmissive plastic layer, such as may be a PMMA (plexiglas) layer.

The existing plastic electronic equipment shell can only realize the plane texture appearance effect of single color through surface lamination or coating color layers, and cannot realize the three-dimensional appearance effect. According to the technical scheme provided by the embodiment of the application, the three-dimensional texture effect can be displayed through the target layer 111 on the surface of the substrate layer 113.

The first direction F1 is a direction in which the outside of the electronic device points inward. If the substrate layer 113 can be arranged close to the outside of the electronic device, the target layer 111 and the optical layer 112 are protected by the substrate layer 113, and the target layer 111 and the optical layer 112 are prevented from being damaged by external force.

In the embodiment of the present application, the substrate layer 113 and the target layer 111 are both light-transmitting material layers. The substrate layer 113 is adjacent to the outside of the electronic device and the target layer 111 is adjacent to the inside of the electronic device. After the external ambient light is incident into the housing 11, the incident light can be refracted and/or reflected by different layers of textures in the first three-dimensional texture pattern 12, so that the housing 11 exhibits a cool light effect. In addition, after the light is incident on the optical layer 112 below the target layer 111, the scattering effect of the light inside the housing 11 can be further improved by adjusting the light by the optical layer 112, and the cool light effect of the housing 11 can be further improved.

In the embodiment of the present application, as shown in fig. 1 and 6, the housing 11 includes at least one cambered surface;

the base material layer 113, the target layer 111, and the optical layer 112 are simultaneously formed into a case having at least one cambered surface by hot-press high-temperature molding. In other embodiments, the housing may be a flat plate structure, and the substrate layer 113, the target layer 111, and the optical layer 112 may form a flat plate housing structure simultaneously.

Referring to fig. 7, fig. 7 is a schematic structural diagram of an optical layer in an electronic device housing according to an embodiment of the present application, where the optical layer 112 at least includes:

an optical cement pattern layer 21, the optical cement pattern layer 21 having a second stereoscopic texture pattern 23;

the coating color layer 22, the coating color layer 22 has a plurality of first light-transmitting films and second light-transmitting films alternately arranged, and the refractive indexes of the first light-transmitting films and the second light-transmitting films are different. The first light-transmitting film and the second light-transmitting film are sequentially laminated in the first direction F1.

Wherein the thickness of the optical adhesive pattern layer 21 is not more than 0.05mm. The optical cement pattern layer 21 of a desired pattern structure may be formed through an optical transfer process.

Optionally, one of the first light-transmitting film and the second light-transmitting film is a silicon dioxide film, and the other is a titanium dioxide film. In the coating color layer 22, the thickness of the single-layer thin film is 200nm-500nm, and the thickness of each film layer in the coating color layer 22 can be set according to the requirement, and the thickness of the film layer in the coating color layer 22 is not limited in the embodiment of the application.

By setting the film thickness of the film coating color layer 22, the film coating color layer 22 has an antireflection effect on yellow light, for example, the reflectivity of the shell 11 on yellow light can be reduced, so that when the target layer 111 is prepared by adopting an acetic acid material, the problem of reduced visibility of acetic acid texture caused by yellowing of the acetic acid material can be reduced to a certain extent due to the fact that the shell 11 can reduce the reflection on yellow light.

In the optical layer 112 shown in fig. 7, the second three-dimensional texture pattern 23 based on the surface of the optical adhesive pattern layer 21 can increase the interface between optical reflection and refraction, thereby increasing the reflection and refraction times of light in the housing 11, and better improving the appearance display light efficiency. Optionally, the optical adhesive pattern layer 21 has a second three-dimensional texture pattern 23 on a surface of the optical adhesive pattern layer 21 facing the target layer 111, so that a surface of the optical adhesive pattern layer 21 facing away from the target layer 111 can be ensured to have better flatness, so that a film can be coated on the surface to form the coated color layer 22.

In the optical layer 112 shown in fig. 7, the optical diffraction effect can be achieved based on the two light-transmitting films with different refractive indexes in the film-coated color layer 22, so that the ambient light entering the housing 11 forms a color appearance effect after being emitted again through the optical layer 111.

In order to further enhance the diversity of the appearance effect of the housing 11, a side of the substrate layer 113 facing away from the target layer 111 may be provided with a predetermined pattern. The preset pattern comprises at least one of the following modes: a first pattern formed on a surface of one side of the substrate layer 113 facing away from the target layer 111 through a surface rubbing process; a second pattern formed on a surface of one side of the substrate layer 113 facing away from the target layer 111 through a shower coating process; the third pattern is formed on the surface of the substrate layer 113 facing away from the target layer 111 through an etching process, which includes laser etching, wet etching, or the like.

Referring to fig. 8, fig. 8 is a sectional view of a housing of another electronic device according to an embodiment of the present application, and on the basis of the manner shown in fig. 6, the housing 11 shown in fig. 8 further includes: a base color layer 115 on a side of the optical layer 112 facing away from the target layer 111; a surface protection layer 114 located on a side of the base material layer 113 facing away from the target layer 111.

The protective layer 114 may improve the abrasion resistance of the outer surface of the housing 11. The under color layer 115 has a set color, and can enhance the reflection effect of the case 11 on the set color light wave in the external ambient light, so that the case 11 exhibits a desired color.

The case 11 may be set to include, based on the demand: the side of the substrate layer 113 facing away from the target layer 111 has at least one of a preset pattern, a primer layer 115, and a protective layer 114.

Referring to fig. 9, fig. 9 is a schematic structural diagram of still another electronic device housing according to an embodiment of the present application, in a first direction F1, the housing 11 includes a protective layer 114, a base material layer 113, an adhesive layer 116, a target layer 111, an optical layer 112 (including an optical paste pattern layer 21 and a coating color layer 22), and a primer layer 115, which are sequentially stacked. The adhesive layer 116 may be an optical adhesive layer, such as a UV adhesive layer. The base color layer 115 may be an ink layer.

As described above, the substrate layer 113 is made of PMMA, the target layer 111 is made of an acetate film, and the adhesive layer 116 is made of an optical adhesive layer, for example, the acetate film may be adhered and fixed on the surface of the PMMA layer facing the inside of the electronic device through the optical adhesive layer, so as to form a PMMA composite board shell structure based on the PMMA layer. The PMMA layer and the acetic acid material film can be better adhered and fixed by adjusting the viscosity and other parameters of the optical adhesive layer. And PMMA composite sheet can be earlier through 2D (two-dimensional) plane laminating technology preparation back, carry out 3D (three-dimensional) casing shaping again, compare in 3D glass's casing, when having avoided 3D glass casing to need 3D shaping earlier and laminating film afterwards, the problem that the film takes place the fold easily, can be applicable to various 3D curved surface figurative casing designs.

Optionally, at least one side surface of the opposite side surfaces of the target layer 111 is provided with an inorganic coating layer in the first direction F1, so as to improve the surface compactness of the film layer, and prevent the target layer 111 from being corroded by water vapor.

When the target layer 111 includes an acetic acid material, an acetic acid film with a desired pattern can be prepared in advance as the target layer 111 by a dry process or a wet process, and the pattern on the acetic acid film can be prepared into multiple layers and multiple colors based on the requirement, so that a pattern similar to a natural texture is realized, which is a pattern effect that cannot be realized by nano photoresist.

When the target layer 111 includes an acetic acid material, the target layer 111 can be made to realize a rich texture based on one layer of acetic acid film, thereby realizing a rich appearance effect of the housing 11. The first stereoscopic texture pattern 12 can be realized based on the multi-layered texture and color of the acetic acid film itself as the target layer 111.

Further, the appearance color effect and the three-dimensional pattern effect of the housing 11 can be further enhanced by the optical layer 112. Specifically, the optical cement pattern layer 21 having the second stereoscopic vein pattern 23 may be prepared by transferring a UV optical cement layer on the surface of the target layer 111, and the coating color layer 22 may be prepared by a coating process to form the optical layer 112 on the surface of the target layer 111. On the one hand, the mode is not required to be independently attached with a diaphragm with larger fixed thickness, the manufacturing cost is low, the thickness of the shell 11 is not greatly increased, on the other hand, the coating color layer 22 is an inorganic coating film, and a better optical adjusting effect can be realized by the thinner thickness. In addition, the second stereoscopic texture pattern 23 is different from the first stereoscopic texture pattern 12, and the superposition of the two patterns can realize a richer and more diversified three-dimensional pattern effect.

As can be seen from the above description, the electronic device housing provided by the embodiment of the present application can realize multi-layer and multi-color rich three-dimensional texture patterns by using one layer of acetic acid film, and the thickness of the film layer in the housing 11 is thinner, so that the manufacturing cost is low. The three-dimensional texture pattern of the housing 11 may be customized, unique, pattern-wise by acetate fibers in the acetate film.

Referring to fig. 10, fig. 10 is a schematic view showing an appearance effect of an electronic device case according to an embodiment of the present application, and fig. 10 shows a rear case of a mobile phone formed by a target layer 111 made of four different acetic acid films. The three-dimensional texture pattern of the housing 11 may be customized, unique, pattern-wise by acetate fibers in the acetate film.

In combination with the schematic structural diagram of the case 11 in the above embodiment and as shown in fig. 10, in the case 11 provided in the embodiment of the present application, the target layer 111 can form a three-dimensional pattern effect with a three-dimensional contour based on the acetic acid film, so as to form the first three-dimensional texture pattern 12. Based on the optical layer 112 below the target layer 111, the reflection effect of the light on the gloss subareas of the textures of different levels in the first stereoscopic texture pattern 12 can be made different, so that the housing 11 can display a plurality of gloss subareas with different brightness in appearance effect, such as the marked gloss subareas 100 and the gloss subareas 200 in fig. 10 have different brightness. The reflection/refraction effects of light in the housing 11 are different at different viewing angles, so that the same three-dimensional texture pattern profile in the same housing can show gloss subregions with different brightness distributions. Further, the diversity of the external patterns of the case and the diversity of the brightness under different viewing angles can be further increased by combining the surface patterns of the substrate layer 113 on the side facing away from the target layer 111.

Based on the embodiment of the electronic device housing provided in the foregoing embodiment, another embodiment of the present application further provides a method for manufacturing an electronic device housing.
