Technical Field

The application relates to the technical field of electronic equipment, in particular to a shell, a preparation method and electronic equipment.

Background

Current electronic devices (e.g., smart phones) increasingly use glass as an interface for interacting with a user, i.e., the housing of the electronic device is a glass substrate. In addition to the bright side of the glass, more and more consumers want to have a corresponding design on the glass and a different feel on the glass, one of which is to use an anti-glare matte finish.

However, the existing housing with the matte effect, the preparation method thereof and the electronic device still need to be improved.

Content of application

The present application is based on the discovery and recognition by the inventors of the following facts and problems:

the inventor finds that the existing shell cannot have the effect of gradually changing the fog surface, and the appearance of the shell needs to be improved. Specifically, it is well known to those skilled in the art that the matte effect is usually obtained by etching the glass surface with chemicals. However, the current shell usually has a uniform matte surface (i.e., uniform etching throughout the preparation process) or a sudden change in matte surface (i.e., sudden change etching during the preparation process), and cannot have a gradual change in matte surface. Although there is a solution for preparing a fog-surface gradual-change shell by using a laser engraving device, the surface of the shell is provided with a plurality of pits arranged in an array, and the diameter and depth of each pit are gradually increased and deepened along a predetermined direction. However, the above method is costly, and the glass surface is whitish and has no aesthetic feeling and texture.

The present application aims to mitigate or solve at least to some extent at least one of the above mentioned problems.

Therefore, the shell with the fog surface gradual change effect can be obtained by a simple method, the method has the advantages of simplicity in operation, low cost and the like, and the obtained shell has better aesthetic feeling and texture.

In another aspect of the present application, a housing is presented. The shell is prepared using the method described previously. Therefore, the shell has the appearance of gradually changed fog surface, has better aesthetic feeling and texture and has lower cost.

In another aspect of the present application, a housing is presented. The housing includes: the glass substrate comprises a glass substrate, wherein the surface of the glass substrate is provided with a fog face part, and the thickness of the glass substrate at the fog face part is gradually changed along at least one preset direction. Therefore, the shell has the appearance of gradually changed fog surface and has better aesthetic feeling and texture.

In another aspect of the present application, an electronic device is presented. The electronic device includes: a housing, said housing being as previously described; mainboard and display screen, the mainboard with the display screen sets up the casing is not provided with one side of fog face portion, just the mainboard is close to the casing sets up, the light-emitting side of display screen is kept away from the casing sets up. Thus, the electronic device has all the features and advantages of the housing described above, which are not described in detail herein. Generally speaking, the electronic equipment has the appearance of fog gradual change and has better aesthetic feeling and texture.

Detailed Description

Reference will now be made in detail to examples of the present application, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The examples described below with reference to the drawings are illustrative only for the purpose of explaining the present application and are not to be construed as limiting the present application.

In one aspect of the present application, a method of making a housing is presented. In some examples of the present application, with reference to fig. 1, the method includes:

s100: arranging protective ink on a predetermined area of the surface of a glass substrate rough blank

In this step, a protective ink is provided on a predetermined region of the surface of the glass substrate blank. The specific material for protecting the ink is not particularly limited as long as the glass substrate blank of the predetermined region can be protected from etching in the subsequent chemical etching process, and can be designed by those skilled in the art according to the actual situation.

The "predetermined region" means a region where the surface of the glass substrate blank is not required to have the matte effect, for example, the entire inner surface of the glass substrate blank, or the entire inner surface and a part of the outer surface of the glass substrate blank. The term "outer surface" refers to a surface of the housing exposed to the outside after the housing and other components are assembled into the electronic device, and the term "inner surface" refers to a surface opposite to the outer surface.

The process for producing the glass substrate blank is not particularly limited, and can be designed by those skilled in the art according to a usual process. The specific structure of the glass substrate blank is also not particularly limited, and the glass substrate blank may be, for example, 2D, 2.5D, or 3D glass.

S200: chemically etching the glass substrate blank provided with the protective ink to form a matte part

In this step, the glass substrate blank provided with the protective ink is chemically etched to form a haze surface portion. In the chemical etching process, the part of the glass substrate rough blank which is not covered by the protective ink reacts with the etching liquid to form a fog face part at the part outside the preset area, and the thickness of the glass substrate rough blank at the fog face part is gradually changed along at least one preset direction by controlling the condition of the chemical etching, so that the shell with the fog face gradual change effect is obtained.

In some examples of the present application, the haze-grading effect may be achieved by exposing different portions of the surface of the glass substrate blank to different concentrations of the etchant in the etching solution during the chemical etching process. Namely, the concentration difference of the etchant in the etching solution exists, the etching amount is larger in a region with high concentration of the etchant, the etching amount is smaller in a region with low concentration of the etchant, and the concentration of the etchant is gradually changed, so that the thickness of the glass substrate at the fog face part is gradually changed along at least one preset direction, and the fog face gradual change effect is formed.

The specific direction and the specific number with respect to the predetermined direction are not particularly limited, and those skilled in the art can design according to the actually required appearance effect.

In some examples of the present application, the etchant described above may include a main reactant and a side reactant, and the etchant further includes a dispersed precipitant, and the concentration difference between the etchant and the dispersed precipitant may be adjusted by adjusting the contents of the side reactant and the dispersed precipitant and adjusting the precipitation time of the dispersed precipitant, so that the concentration of the etchant at different depths is different and gradually changed. Wherein the main reactant comprises ammonium bifluoride, and the side reactant comprises hydrogen ions and sulfate ions. Specific components regarding the side reactant are not particularly limited, for example, the side reactant may include sulfuric acid, or the side reactant may include sulfuric acid and at least one of hydrochloric acid, nitric acid, oxalic acid, ammonium sulfate, or the side reactant may include ammonium sulfate and at least one of hydrochloric acid, nitric acid, oxalic acid. The main reactant can provide fluorine ions, the side reactant can provide hydrogen ions and sulfate ions, the hydrogen ions and the fluorine ions can form hydrofluoric acid, the hydrofluoric acid reacts with glass to etch the glass, the side reactant contains the sulfate ions to dissolve formed fluosilicate (such as ammonium fluosilicate) and adjust the roughness depth of the glass, the side reactant can also adjust the concentration of various ions in the etching solution, the concentration of various ions is kept in a proper range, and the pH value of the etching solution can also be adjusted. The dispersed precipitant may include barium sulfate, and after the precipitation of the dispersed precipitant is started, the amount of the dispersed precipitant at different depths is different, so that the concentration of the etchant at different depths is different, for example, in a region with a large amount of the dispersed precipitant, the concentration of the etchant is relatively low, in a region with a small amount of the dispersed precipitant, the concentration of the etchant is relatively high, and since the precipitation of the dispersed precipitant is a continuous and gradual deposition process, the concentration of the etchant is also gradually changed, so that the thickness of the glass substrate blank at the matte surface is gradually changed, and finally, the effect of gradual change of the matte surface is obtained.

Although barium sulfate is a dispersion precipitant, barium sulfate has a certain solubility in the system (i.e., barium sulfate is not completely precipitated or dissolved), and the side reactant prevents Ba from being present²⁺And the glass substrate rough blank reacts with other anions to form precipitates, so that the concentration of various ions is kept in a proper range, a stable chemical reaction environment is maintained, and the glass substrate rough blank can obtain a regularly and gradually changed matte effect after being chemically etched.

In this application, the etching solution can generate the triangular pyramid crystal particles after reacting with the glass, and after washing away the triangular pyramid crystal particles, can form the pit on the glass surface, and when light shines the glass surface, because there is the pit, make light take place the scattering, reduce the luminousness on glass surface, in order to form the matte effect. The triangular conical crystal particles are fluorosilicate, specifically ammonium fluorosilicate and barium fluorosilicate.

The specific adjustment of the content of the side reactant and the dispersed precipitant and the precipitation time of the dispersed precipitant is not particularly limited as long as the effect of gradual change of the haze can be obtained, and those skilled in the art can design according to the actually required effect of gradual change of the haze.

In some examples of the present application, the chemically etching using the etching liquid may include: after the precipitation of the dispersion precipitant begins, the glass substrate blank is placed into the etching solution, and the glass substrate blank is taken out of the etching solution before the dispersion precipitant is completely precipitated. Therefore, before the glass substrate rough blank is placed into the etching liquid, the concentration difference of the etching agent in the etching liquid is formed, so that the placing direction of the glass substrate rough blank is adjusted, the etching agent with different concentrations is contacted at different positions on the surface of the glass substrate rough blank, and the glass substrate rough blank is taken out before the dispersed precipitating agent is completely precipitated, so that the concentration of the etching agent contacted at different positions on the surface of the glass substrate rough blank is different in the etching process, and after the glass substrate rough blank is placed in the etching liquid for a certain time, the thickness of the glass substrate rough blank at the formed fog surface part can be gradually changed, and the fog surface gradual change effect is formed.

It should be noted that, after the dispersion precipitant begins to precipitate and before the dispersion precipitant completely precipitates, the time range is relatively wide, and those skilled in the art may put the glass substrate blank into the etching solution after the dispersion precipitant precipitates for a certain time. The time node for the specific insertion and removal of the glass substrate blank is not particularly limited, and those skilled in the art can design the time node according to the actually required matte-surface-gradient effect.

The direction in which the glass substrate rough blank is put is not particularly limited, and for example, the glass substrate rough blank is a rectangular case, and the glass substrate rough blank may be put into the etching solution along the long side direction of the glass substrate rough blank, or the glass substrate rough blank may be put into the etching solution along the short side direction of the glass substrate rough blank, or the glass substrate rough blank may be put into the etching solution along the diagonal direction of the glass substrate rough blank, which is not listed here.

In some examples of the present application, the etching liquid may include: 30-40 wt% of ammonium bifluoride, 5-10 wt% of sulfuric acid, 2-8 wt% of barium sulfate and the balance of water. It should be noted that, since the side reactant exists in an ionic state, the "sulfuric acid" herein may also refer to sulfuric acid formed by hydrogen ions (e.g., hydrogen ions in hydrochloric acid) and sulfate ions (e.g., sulfate ions in ammonium sulfate) in the side reactant. The inventors found that if the content of sulfuric acid is too large (e.g., greater than 10 wt%), the amount of hydrofluoric acid formed by sulfuric acid and ammonium bifluoride is too large, the reaction speed is too fast, the haze of the case is reduced, and the haze gradient effect cannot be exhibited, and that the case thickness is thinner due to a large etching amount, and if the content of sulfuric acid is too small (e.g., less than 5 wt%), the amount of hydrofluoric acid formed by sulfuric acid and ammonium bifluoride is too small, the reaction is slow, the roughness of the glass is small, and the haze gradient effect cannot be exhibited. If the content of the dispersed precipitant is too large (e.g., greater than 8 wt%), the precipitation time at the early stage is too long, and the efficiency is low, and if the content of the dispersed precipitant is too small (e.g., less than 2 wt%), the concentration difference formed by the etchant is small, so that the haze gradual change effect of the shell is not obvious. The proportion of each component in the etching liquid is optimized, so that the gradual change of the matte effect of the shell obtained after etching in the system is facilitated.

In other examples of the present application, the haze-grading effect may be achieved by exposing the glass substrate blank to the etching solution at different locations during the chemical etching process. Namely, the temperature difference exists in the etching solution, the reaction speed is higher in the area with higher temperature of the etching solution, the reaction speed is lower in the area with lower temperature of the etching solution, and the temperature of the etching solution is gradually changed, so that the thickness of the glass substrate at the matte part is gradually changed along at least one preset direction, and the effect of gradual change of the matte is formed. In this example, the etching solution may be an etching solution commonly used in the art, after the glass is etched by the etching solution, pits are formed on the surface of the glass to form a matte effect, and by forming a temperature difference in the etching solution, the reaction rates at different areas of the glass substrate blank may be different, so that the thickness of the glass substrate blank at the matte area is gradually changed. Alternatively, the etching liquid may be the etching liquid described above, i.e. having a dispersed precipitant capable of forming a concentration difference. Therefore, the final appearance effect of the shell is the combined effect of two modes of regulating the concentration of the etching agent and regulating the temperature of the etching solution, so that the shell obtains the fog surface gradual change effect.

In some examples of the present application, the forming of the etching solution into the temperature difference may be performed by applying a first temperature to the bottom of the container containing the etching solution and applying a second temperature to the upper side of the etching solution, wherein the first temperature and the second temperature are different, so that the temperatures at different depths of the etching solution are different and gradually change. Therefore, the temperatures of the top and the bottom of the etching liquid are different, so that a temperature difference is formed in the etching liquid, and the temperatures of different depths of the etching liquid are gradually changed, so that the thickness of the glass substrate rough blank at the matte part is gradually changed, and the effect of gradual change of the matte is finally obtained.

The specific application manner of the first temperature and the second temperature is not particularly limited, and for example, the container containing the etching solution may be placed in an ice-water compound to reduce the temperature of the bottom of the etching solution to about 0 ℃ and expose the top of the etching solution, i.e., the temperature of the top of the etching solution is ambient temperature (e.g., room temperature 25 ℃), thereby forming a temperature difference in the etching solution. Or, the container containing the etching liquid is placed in the ice water compound to reduce the temperature of the bottom of the etching liquid to about 0 ℃, a heating device is arranged above the etching liquid, the heating device can be suspended or contacted with the etching liquid, and a temperature difference is formed in the etching liquid by adjusting the temperature of the heating device (such as higher than 25 ℃), so that the gradual change effect is further controlled.

In some examples of the present application, during the chemical etching, after a temperature difference is formed at different depths of the etching solution, the glass substrate blank is placed in the etching solution, and after etching for a predetermined time, the glass substrate blank is taken out of the etching solution. By adjusting the placing direction of the glass substrate rough blank, different positions on the surface of the glass substrate rough blank are contacted with etching solutions with different temperatures, so that the reaction speeds of the different positions of the glass substrate rough blank are different, the etching amount is different, the thickness of the glass substrate rough blank at the formed matte part is gradually changed, and the matte gradual change effect is formed.

The specific time for applying the first temperature and the second temperature is not particularly limited, and those skilled in the art can design depending on the material and thickness of the container for containing the etching solution as long as a temperature difference is formed in the etching solution.

In the application, after the glass substrate rough blank is chemically etched, the protective ink on the surface of the glass substrate rough blank is removed to obtain the glass substrate, and then the glass substrate can be subjected to conventional treatment, such as chemical polishing, chemical strengthening, surface decoration (such as film pasting or ink spraying) and the like.

In another aspect of the present application, a housing is presented. In some examples of the present application, the housing is prepared by the method described above. Therefore, the shell has the appearance of gradually changed fog surface, has better aesthetic feeling and texture and has lower cost.

In some examples of the present application, the roughness of the matte surface of the shell gradually varies between 0.01 μm and 3 μm. Therefore, the fog face part has obvious gradual change effect, and the roughness is in a region of more than 1 μm, so that the hand-held toothbrush has good holding feeling.

In some examples of the present application, the haze of the haze face portion of the housing varies gradually between 20% and 95%. Therefore, the fog face part has obvious gradual change effect.

In some examples of the present application, the gloss (20 degree angle test) of the fog face portion of the shell is gradually varied between 10-50 degrees. Therefore, the fog face part has obvious gradual change effect.

The roughness of the matte part of the shell gradually changes from 0.01 μm to 3 μm, and the roughness of the matte part gradually changes from 0.01 μm to 3 μm, or the roughness of the matte part gradually changes in a small range between 0.01 μm and 3 μm, for example, the roughness of the matte part gradually changes from 0.2 μm to 0.6 μm. Similarly, the haze of the fog face part gradually changes from 20% to 95%, and may be gradually changed from 20% to 95%, or gradually changed within a small range from 20% to 95%, for example, gradually changed from 30% to 80%. The glossiness of the matte part gradually changes from 10 to 50, and may be gradually changed from 10 to 50, or gradually changed within a small range of 10 to 50, for example, the haze of the matte part gradually changes from 15 to 40.

In some examples of the present application, the maximum value of the matte roughness may be 1 or more times the minimum value, similarly, the maximum value of the matte haze may be 1 or more times the minimum value, and the maximum value of the matte gloss may be 1 or more times the minimum value. From this, the casing has more obvious matte gradual change effect, gives the stronger perception dynamics of user.

In another aspect of the present application, a housing is presented. In some examples of the present application, the housing includes: the glass substrate is provided with a matte part on the surface, and the thickness of the glass substrate at the matte part is gradually changed along at least one preset direction. Therefore, the shell has the appearance of gradually changed fog surface and has better aesthetic feeling and texture.

In some examples of the present application, the housing may be prepared using the methods described above. Therefore, the shell has a good fog face gradual change effect and is low in cost.

The roughness, haze and glossiness of the haze portion of the case have been described in detail previously, and are not described in detail.

In another aspect of the present application, an electronic device is presented. In some examples of the present application, the electronic device includes: casing, mainboard and display screen, casing are the casing of preceding description, and mainboard and display screen setting are not provided with the one side of fog face portion at the casing, and the mainboard is close to the casing setting, and the casing setting is kept away from to the light-emitting side of display screen. Thus, the electronic device has all the features and advantages of the housing described above, which are not described in detail herein. Generally speaking, the electronic equipment has the appearance of fog gradual change and has better aesthetic feeling and texture.
