DETAILED DESCRIPTION

[0029] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0030] Currently, more and more electronic devices such as mobile phones use glass casings as outer shells, and are combined with decorative film layers to enhance the aesthetics of the electronic devices.

[0031] However, electronic devices with glass casings equipped with decorative film layers in the related art suffer from low product yields and high costs. For example, glass casings in the related art are often used as battery covers for electronic devices to enhance their aesthetics. The glass casing comprises a glass substrate, a film layer disposed on the inner surface of the glass substrate, and a decorative film layer disposed on the outer surface of the glass substrate. The decorative film layer is typically an externally coated colorful film. This allows the color effects of the film layer through the glass substrate to overlap with the color effects of the externally coated colorful film, resulting in a richer color variation for the glass casing. However, this configuration of the glass casing, on the one hand, results in significant color fluctuations due to the multiple overlapping color layers, making it difficult to ensure product consistency. Furthermore, when used as a battery cover, for example, the glass casing may have curved edges around its perimeter. The externally coated colorful film in these curved edges may exhibit color variations, further complicating product consistency and resulting in low product yields. Furthermore, the externally coated colorful film is subject to film thickness restrictions, requiring a thickness greater than 500 nm to ensure reliability and adhesion, which increases the cost of the glass casing.

[0032] In addition, since the colorful film itself has color, when the glass shell provided with the colorful film is worn, it will cause a mottled visual effect, thereby affecting the aesthetics of the glass shell.

[0033] To address the above technical issues, the present disclosure provides a housing structure in which an effect layer and a brightness-enhancing film layer are sequentially stacked on a first surface of a glass substrate, and a film layer is stacked on a second surface of the glass substrate. The brightness-enhancing film layer thus prevents color fluctuations and color mismatches, thereby improving the product yield of the housing structure. Furthermore, since the brightness-enhancing film layer has no thickness restrictions, it also helps reduce costs.

[0034] An exemplary embodiment of the present disclosure provides a housing structure, such as Figure 1 As shown, the housing structure 1 includes a glass substrate 11, an effect layer 12, a brightness-enhancing film layer 13, and a film layer 14. The glass substrate 11 includes a first surface and a second surface opposite to each other. The effect layer 12 is formed on the first surface, for example, by processing the first surface of the glass substrate 11. It should be noted that the effect layer 12 is a layer capable of enhancing visual effects, such as a frosted layer, a diamond layer, a velvet layer, a sparkling sand layer, etc. formed on the first surface of the glass substrate 11. The brightness-enhancing film layer 13 is superimposed on the effect layer 12 to enhance the brightness-enhancing effect of the housing structure 1.

[0035] The diaphragm layer 14 is stacked on the second surface. The diaphragm layer 14 is a colored diaphragm. For example, the colored diaphragm layer 14 can be made on a polyethylene terephthalate (PET) or polycarbonate (PC) diaphragm by processes such as offset printing, UV transfer printing, electroplating, and silk screen ink. It is understood that offset printing is a type of flat printing that uses a rubber to transfer the image on the printing plate to the substrate. The UV transfer process is a process that uses UV glue to solidify under ultraviolet light to replicate fine texture structures through the phenomenon of curing. The UV transfer process is also called UV perfusion process or UV batch coating process. It uses the non-stick property of UV transfer glue to transfer various brushed patterns from PET or PC sheets to another piece of glass through the UV transfer process, thereby creating CD texture, brushed texture, matte surface, glossy surface, etc. Electroplating refers to the process of plating a layer of metal on a metal or non-metal surface through an electrochemical method. Silk screen ink is also called screen printing ink. The basic principle of silk screen printing is to use the mesh of the graphic part on the screen printing plate to pass the ink, while the mesh of the non-graphic part cannot pass the ink, thereby achieving printing.

[0036] In this embodiment, the effect layer 12 and the brightness enhancement film layer 13 are sequentially stacked on the first surface of the glass substrate 11, and the film layer 14 is stacked on the second surface of the glass substrate 11. In this way, the setting of the brightness enhancement film layer 13 does not change the color of the film layer 14, effectively improving the color texture of the film layer 14, and at the same time, cooperating with the effect layer 12 to enhance the visual effect of the shell structure 1, thereby effectively improving the aesthetics of the shell structure 1.

[0037] Compared to color-blocking films, the brightness-enhancing film layer 13 exhibits relatively stable color fluctuations, thereby improving color consistency. Furthermore, it avoids visible color variations due to bending of the glass shell, effectively improving the product yield of the shell structure 1. Furthermore, the brightness-enhancing film layer 13 is not limited by film thickness, resulting in higher production capacity and yield compared to color-blocking films, thus contributing to cost reduction. Furthermore, in this embodiment, the degree of wear and tear on the shell structure 1 has minimal impact on its color and visual effects, further ensuring the aesthetics and visual quality of the shell structure 1.

[0038] In one embodiment, the brightness-enhancing film 13 comprises a coating. For example, a high-energy magnetron sputtering device can be used to generate plasma by glow discharge of an inert gas (typically argon). After being accelerated by an electric field, the plasma impacts the target surface, knocking target atoms out and depositing them on the effect layer 12, forming a thin film that constitutes the brightness-enhancing film 13. This configuration simplifies the installation of the brightness-enhancing film 13 and facilitates production and processing, thereby improving the production efficiency of the housing structure 1.

[0039] In one embodiment, the effect layer 12 includes a shimmering sand layer. This shimmering sand layer imparts a shimmering effect to the glass substrate 11. Forming the shimmering sand layer on the first surface of the glass substrate 11 enhances the visual effect of the housing structure 1 and further improves its aesthetics. Furthermore, the shimmering sand layer improves the adhesion of the brightness-enhancing film layer 13, thereby enhancing the wear resistance and production yield of the housing structure 1.

[0040] In one embodiment, the housing structure 1 further includes a concave-convex structure formed on the first surface of the glass substrate 11, which constitutes a shimmering sand layer. For example, the first surface of the glass substrate 11 can be etched using HF generated by the aging of H2SO4, HCl, HNO3, NH4HF2, and NH4F. This reaction generates precipitated salts such as fluorosilicates and fluoroaluminates, which accumulate on the first surface of the glass substrate 11 and hinder further etching by HF. This creates an uneven surface, i.e., a concave-convex structure, on the first surface of the glass substrate 11, thereby forming the shimmering sand layer. By controlling the grain shape, size, and arrangement of the concave-convex structure through process control, the shimmering sand layer can exhibit different shimmering effects under illumination, further enhancing the aesthetics of the housing structure 1.

[0041] In one embodiment, the surface roughness of the flash sand layer is 3 μm to 4 μm, for example 3.5 μm. The surface roughness of the flash sand layer formed on the first surface of the glass substrate 11 is 3 μm to 4 μm, which can effectively ensure the visual effect of the housing structure 1.

[0042] In one embodiment, the thickness of the brightness enhancement film layer 13 is 145 nm to 155 nm, for example, 150 nm. This effectively reduces the thickness of the housing structure 1 while maintaining the brightness enhancement effect of the housing structure 1 and improving the color and texture of the film layer 14. This not only further reduces production costs, but also facilitates the thinning design of electronic devices and enhances the user experience.

[0043] In another embodiment, the sum of the thicknesses of the glass substrate 11 and the effect layer 12 is 0.4 mm to 0.6 mm, for example 0.5 mm. That is, after the effect layer 12 is formed on the first surface of the glass substrate 11, the overall thickness of the glass substrate 11 is 0.4 mm to 0.6 mm. This arrangement, on the one hand, reduces the increase in thickness of the housing structure 1 while ensuring the visual effect of the housing structure 1, thereby facilitating the thinning design of electronic devices. On the other hand, it avoids a reduction in the structural strength of the housing structure 1 due to the smaller overall thickness of the glass substrate 11 after the effect layer 12 is formed on the first surface of the glass substrate 11, thereby ensuring the reliability of the housing structure 1.

[0044] In one embodiment, the brightness enhancement film 13 has a thickness of 145 nm to 155 nm, and the combined thickness of the glass substrate 11 and the effect layer 12 is 0.4 mm to 0.6 mm. This design reduces production costs while ensuring the structural strength of the housing structure 1, thereby improving the reliability of the housing structure 1.

[0045] Combine Figure 2 In one embodiment, the housing structure 1 further includes an anti-fingerprint film layer 15, which is disposed on the brightness enhancement film layer 13. For example, a hydrophobic film layer can be formed on the brightness enhancement film by spraying or other means. The provision of the anti-fingerprint film layer 15 effectively prevents fingerprint adhesion, thereby protecting the housing structure 1 from fingerprints and ensuring the clarity of the housing structure 1. Furthermore, the anti-fingerprint film layer 15 can also reduce the wear rate of the housing structure 1 to a certain extent, thereby not only improving the reliability of the housing structure 1 and extending the service life of the housing structure 1, but also maintaining the visual effect of the housing structure 1 and enhancing its aesthetics.

[0046] In one embodiment, the anti-fingerprint film layer 15 has a thickness of 6 nm to 10 nm, for example, 8 nm. This configuration effectively reduces the thickness of the housing structure 1 while ensuring the clarity of the housing structure 1. This not only further reduces production costs, but also facilitates the thinning design of electronic devices and improves the user experience.

[0047] Combine Figure 3 In one embodiment, the film layer 14 includes an optical adhesive layer 141, a transparent substrate 142, a texture layer 143, a coating decorative layer 144, and a first ink layer 145 stacked in sequence. The optical adhesive layer 141 is bonded to the second surface. For example, the transparent substrate 142 can be a film substrate made of PET or PC, and the optical adhesive layer 141 can be an optically clear adhesive (OCA). The optical adhesive layer 141 is provided on one surface of the transparent substrate 142. The texture layer 143 is formed on the other opposite surface of the transparent substrate 142 by offset printing, UV transfer printing, or other processes. The coating decorative layer 144 is formed on the texture layer 143 by electroplating. The first film layer is formed on the coating decorative layer 144 by silk-screening ink, thereby forming the film layer 14. By providing the first ink layer 145 on the coating decorative layer 144, the film layer 14 can present an overall color effect and can also protect the coating decorative layer 144.

[0048] Such a design makes the structure of the membrane layer 14 simple and facilitates production and processing.

[0049] In one embodiment, the thickness of the optical adhesive layer 141 is 23 μm to 27 μm, for example, 25 μm. The thickness of the transparent substrate 142 is 47 μm to 53 μm, for example, 50 μm. The thickness of the texture layer 143 is 9 μm to 13 μm, for example, 11 μm. The thickness of the coating decorative layer 144 is 375 nm to 385 nm, for example, 380 nm. The thickness of the first ink layer 145 is 28 μm to 36 μm, for example, 32 μm. By setting the thickness of the above-mentioned film layers in this way, the film layer 14 not only has good gloss and color effects, but also has a moderate thickness of each film layer, avoiding waste of material due to excessive thickness of the film layer, thereby further reducing production costs.

[0050] In one embodiment, to facilitate production and processing, the area of the membrane layer 14 is generally not the same as the area of the glass substrate 11. Usually, the area of the membrane layer 14 is set to be smaller than the area of the glass substrate 11, so that there is a gap between the edge of the membrane layer 14 and the edge of the second surface. Based on this, combined with Figure 4 The shell structure 1 also includes a second ink layer 16, which is superimposed on the spacing area of the second surface. The second ink layer 16 is provided to supplement the color of the spacing area. For example, the second ink layer 16 and the first ink layer 145 have the same color, thereby effectively improving the comprehensiveness and consistency of the color distribution of the shell structure 1, avoiding the problem of heterochromaticity, thereby further improving the aesthetics and visual effect of the shell structure 1 and improving the user experience.

[0051] In one embodiment, the surface roughness of the glass substrate 11 is 30 nm to 50 nm, for example, 30 nm, 35 nm, 45 nm, or 50 nm. For example, when preparing the glass substrate 11, a large sheet of glass can be cut into desired sizes, such as the size of a battery cover. The cut glass is then polished using a polishing machine, resulting in a surface roughness of 30 nm to 50 nm. This design effectively improves the refinement of the housing structure 1, thereby enhancing the user experience.

[0052] In one embodiment, a device mounting hole is provided on the glass substrate 11. For example, when the shell structure 1 is used as a battery cover of an electronic device, the device mounting hole is used to install a camera module, for example. The surface roughness of the hole wall of the device mounting hole is 30nm to 50nm, for example, 30nm, 35nm, 45nm or 50nm. For example, when preparing the shell structure 1, after cutting a large piece of glass into the required size, such as the size of a battery cover, a hole can be opened on the cut glass as needed to form a device mounting hole for mounting the device, and then a brush or other consumable material is used to sweep and grind the glass edge and the opening. The surface roughness of the hole wall of the device mounting hole after sweeping and grinding is 30nm to 50nm. In this way, while ensuring that the refinement of the shell structure 1 can be improved, the hole wall of the device mounting hole is prevented from causing scratches or other damage to the device, thereby improving the reliability of the electronic device.

[0053] In one embodiment, the hardness of the glass substrate 11 provided with the effect layer 12 is greater than 9H. For example, after forming a flash sand layer on the first surface of the glass substrate 11, the substrate is placed in molten salt in a high-temperature furnace. This allows Na ions on the surface of the glass substrate 11 provided with the effect layer 12 to exchange with potassium ions in the molten salt, thereby increasing the hardness of the glass substrate 11 provided with the effect layer 12 to greater than 9H. This effectively ensures the structural strength of the housing structure 1 and improves the reliability of the housing structure 1.

[0054] In one embodiment, the glass substrate 11 is recessed from the second surface toward the first surface. This facilitates the installation of the housing structure 1 and external components, improves the tightness of the connection between the two, and contributes to an enhanced overall aesthetic appearance. For example, when the housing structure 1 is used as a battery cover for an electronic device, the second surface of the housing structure 1 constitutes the inner surface of the battery cover, and the first surface of the housing structure 1 constitutes the outer surface of the battery cover. The recessed second surface of the housing structure 1 facilitates installation of the battery cover on the electronic device and effectively improves the tightness of the connection after installation, thereby improving the reliability of the electronic device while also enhancing its aesthetics.

[0055] A protective oil layer is coated on the second surface of the glass substrate 11. For example, when preparing the glass substrate 11, the second surface, i.e., the concave surface, of the glass substrate 11 can be polished first, and then a layer of protective oil layer is coated on the concave surface after polishing. In this way, the polished second surface can be effectively protected from scratches and other damages, thereby ensuring the refinement of the second surface of the glass substrate 11.

[0056] When the second surface of the glass substrate 11 is concave, the first surface of the glass substrate 11 is correspondingly convex. A logo structure can be provided on the first surface as required. The logo structure serves as a logo, such as a manufacturer's logo, promotional text, or a logo for aesthetic purposes. This facilitates identification and promotion of the housing structure 1.

[0057] In one embodiment, the above-mentioned housing structure 1 can be prepared through the following process steps.

[0058] Step 1: Prepare a glass substrate 11.

[0059] In this step, a large sheet of glass is cut into the desired size, such as a battery cover. A hole is then drilled using a grinding wheel using a computerized numerical control (CNC) process. The glass edges and the hole are then polished using a brush or other consumables. The polished glass substrate 11 is then polished using a polishing machine. The surface roughness of the polished glass substrate 11 is 30 to 50 nm. After polishing, a logo structure can be printed on the glass as required.

[0060] Step 2: forming a flash sand layer on the first surface of the glass substrate 11 .

[0061] In this step, the effect of sparkling sand can be achieved by frosting and liquid polishing. For example, the first surface of the glass substrate 11 is etched by HF generated by the aging of H2SO4, HCl, HNO3, NH4HF2, and NH4F, and the reaction generates precipitated salts such as fluorosilicates and fluoroaluminates, which accumulate on the first surface of the glass substrate 11, hindering further etching of HF and causing the first surface of the glass substrate 11 to have an uneven effect, thereby forming a sparkling sand layer. The surface roughness of the sparkling sand layer is 3μm to 4μm. By controlling the shape, size, and arrangement of the grains through process, the sparkling sand layer will also present different sparkling effects under the irradiation of light, thereby further enhancing the aesthetics of the shell structure 1.

[0062] Step 3: Hardening the glass substrate 11 provided with the flash sand layer.

[0063] In this step, after the flash sand layer is formed on the first surface of the glass substrate 11, it is placed in molten salt in a high-temperature furnace to exchange Na ions on the glass surface with potassium ions in the molten salt to improve the strength of the glass and make the hardness of the glass substrate 11 provided with the flash sand layer greater than 9H.

[0064] Step 4: Disposing a brightening film layer 13 on the flash sand layer.

[0065] In this step, high-energy magnetron sputtering equipment can be used to glow discharge an inert gas (usually argon) to generate plasma, which is accelerated by an electric field and then hits the surface of the target material, causing the target atoms to be bombarded out and deposited on the effect layer 12 to form a certain thin film, which constitutes the brightening film layer 13.

[0066] Step 5: Making the membrane layer 14.

[0067] In this step, an optical adhesive layer 141 is provided on one surface of a transparent substrate 142 made of PET or PC material, a texture layer 143 is formed on the other opposite surface of the transparent substrate 142 by offset printing, UV transfer or other processes, a coating decorative layer 144 is formed on the texture layer 143 by electroplating, and a first film layer is formed on the coating decorative layer 144 by silk-screen ink, thereby forming a membrane layer 14.

[0068] Step 6: Lay the film layer on the second surface of the glass substrate 11 .

[0069] In this step, a film laminating device, such as a flip laminating machine, is used. The glass substrate 11 provided with the brightness enhancement film layer 13 as described in step 3 above is placed at one end of the flip laminating machine, and the film layer 14 with the release film removed is placed at the other end of the flip laminating machine. The device is started, and the flip laminating machine laminates the film layer 14 to the second surface of the glass substrate 11 according to the specified accuracy.

[0070] Step 7: Remove bubbles.

[0071] In this step, after the film layer 14 is bonded to the second surface of the glass substrate 11, the optical adhesive has not yet been activated. The glass substrate 11 bonded with the film layer 14 needs to be placed in a degassing device for degassing to improve the bonding effect between the two.

[0072] Step eight: printing the second ink layer 16 .

[0073] In this step, to facilitate production and processing, the area of the membrane layer 14 is generally different from that of the glass substrate 11. Typically, the area of the membrane layer 14 is smaller than that of the glass substrate 11, resulting in a gap between the edge of the membrane layer 14 and the edge of the second surface. Based on this, a second ink layer 16 is superimposed on the gap on the second surface of the glass substrate 11, complementing the color of the gap. Exemplarily, the material after step 6 is placed on a printing table, and the prepared screen printing plate is fixed above the material using a positioning mechanism. The specified ink is poured onto the screen printing plate, and a squeegee is used to apply pressure to the inked area on the screen printing plate. Simultaneously, the other end of the screen printing plate is moved at a constant speed, causing the ink to transfer through the mesh openings of the pattern portion to the gap on the second surface of the glass substrate 11. The ink in the gap constitutes the second ink layer 16. Exemplarily, the thickness of the second ink layer 16 is 5 μm to 8 μm.

[0074] Step 9: Clean.

[0075] In this step, the prepared shell structure 1 is cleaned to improve the refinement of the shell structure 1 .

[0076] An exemplary embodiment of the present disclosure provides an electronic device. The electronic device may be, for example, a mobile phone, a tablet computer, a laptop computer, a PDA, an in-vehicle electronic device, a wearable device (a watch, a bracelet, a ring, etc.), an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA), etc., which requires glass decoration. The electronic device may also be a non-mobile device such as a personal computer (PC), a television (TV), an ATM, or an kiosks, which requires glass decoration.

[0077] The electronic device includes the housing structure 1 as described above. For example, the housing structure 1 may constitute a battery cover of the electronic device. Figure 1 As shown, the housing structure 1 includes a glass substrate 11, an effect layer 12, a brightness-enhancing film layer 13, and a film layer 14. The glass substrate 11 includes a first surface and a second surface that are opposite to each other. The effect layer 12 is formed on the first surface. The brightness-enhancing film layer 13 is stacked on the effect layer 12 to enhance the brightness-enhancing effect of the housing structure 1. The film layer 14 is stacked on the second surface.

[0078] In this embodiment, the effect layer 12 and the brightness enhancement film layer 13 are sequentially stacked on the first surface of the glass substrate 11, and the film layer 14 is stacked on the second surface of the glass substrate 11. In this way, the setting of the brightness enhancement film layer 13 does not change the color of the film layer 14, effectively improving the color texture of the film layer 14, and at the same time, cooperating with the effect layer 12 to enhance the visual effect of the shell structure 1, thereby effectively improving the aesthetics of the electronic device.

[0079] Compared to color-blocking films, the brightness-enhancing film layer 13 exhibits relatively stable color fluctuations, thereby improving color consistency. Furthermore, it avoids visible color variations due to bending of the glass housing, effectively improving the product yield of the housing structure 1. Furthermore, the brightness-enhancing film layer 13 is not limited by film thickness, resulting in higher production capacity and yield compared to color-blocking films, thus contributing to cost reduction. Furthermore, in this embodiment, the degree of wear and tear on the housing structure 1 has minimal impact on its color and visual effects, further ensuring the aesthetics and visual quality of the electronic device.

[0080] An exemplary embodiment of the present disclosure provides an accessory device, comprising the housing structure 1 described above. For example, the accessory device in the embodiment of the present disclosure can be a device that is combined with an electronic device to enhance the functionality of the electronic device, such as a charger (including a wireless charger) or a card reader, which enhances the functionality and / or aesthetics of the electronic device. It can also be a device that protects the electronic device, such as a protective case / shell, a bracket, or other device that enhances the protection or support of the electronic device. It can also be an "active" accessory capable of providing and / or receiving power, or a "passive accessory" without the ability to provide or receive power. When the electronic device broadly includes electronic computers and products controlled by electronic computers, such as robots, automobiles, and other electronic devices, for example, when the electronic device is an automobile, the accessory device in the embodiment of the present disclosure can also be a vehicle body accessory or other additional device that enhances the protection or support of the electronic device. The housing structure can, for example, be a vehicle body accessory or other additional device that enhances the protection or support of the electronic device. The accessory device can be any product that requires glass decoration, and there is no specific limitation on this.

[0081] like Figure 1 As shown, the housing structure 1 includes a glass substrate 11, an effect layer 12, a brightness-enhancing film layer 13, and a film layer 14. The glass substrate 11 includes a first surface and a second surface that are opposite to each other. The effect layer 12 is formed on the first surface. The brightness-enhancing film layer 13 is stacked on the effect layer 12 to enhance the brightness-enhancing effect of the housing structure 1. The film layer 14 is stacked on the second surface.

[0082] In this embodiment, the effect layer 12 and the brightness enhancement film layer 13 are sequentially stacked on the first surface of the glass substrate 11, and the film layer 14 is stacked on the second surface of the glass substrate 11. In this way, the setting of the brightness enhancement film layer 13 does not change the color of the film layer 14, effectively improving the color texture of the film layer 14, and at the same time, cooperating with the effect layer 12 to enhance the visual effect of the shell structure 1, thereby effectively improving the aesthetics of the electronic device.

[0083] Compared to color-blocking films, the brightness-enhancing film layer 13 exhibits relatively stable color fluctuations, thereby improving color consistency. Furthermore, it avoids visible color variations due to bending of the glass housing, effectively improving the product yield of the housing structure 1. Furthermore, the brightness-enhancing film layer 13 is not limited by film thickness, resulting in higher production capacity and yield compared to color-blocking films, thus contributing to cost reduction. Furthermore, in this embodiment, the degree of wear and tear on the housing structure 1 has minimal impact on its color and visual effects, further ensuring the aesthetics and visual quality of the electronic device.
