Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment accessories, and in particular to a method for manufacturing a bracket protective shell and a back plate of the bracket protective shell. Background Art

[0002] Protective cases are used as accessories for electronic devices and can provide all-round protection for electronic devices. With the continuous development of electronic devices, the functions brought by electronic devices are becoming more and more diversified. In application scenarios such as watching videos, office writing, and games, compared to placing electronic devices flat on the desktop for use, users will prefer to use electronic devices at a suitable angle through a bracket. Therefore, a bracket is usually set on the protective case to solve the above problem.

[0003] As a portable accessory, the bracket on a protective case should generally not affect the user experience. For example, if the bracket is directly protruding from the case, when the user is using the phone, the bracket protruding from the surface of the case can easily cause problems such as uncomfortable grip, uneven placement of the phone on the table, and the bracket easily scratching other objects. Therefore, it is usually necessary to create a groove on the surface of the protective case to accommodate the bracket. In existing processes, the groove is machined using a CNC (numerical control) machine. Since the groove is milled on the surface of the protective case (usually made of PC) by a tool, the bottom of the groove will have a cutting edge. For aesthetic reasons and to prevent scratches caused by friction between the bracket and the groove, a layer of Mylar sheet is attached to the bottom of the groove to cover the edge. However, the added Mylar sheet makes the product look awkward, and the attached Mylar sheet is prone to falling off after a long period of use, affecting the user experience. Summary of the Invention

[0004] The present application discloses a method for manufacturing a back plate of a bracket protective case, which is characterized by comprising: A plate material is used as a base layer, and an isolation layer is provided on a designated area of ​​one surface of the base layer; Taking another layer of board as the surface layer and covering the side of the base layer provided with the isolation layer, and compounding the base layer and the surface layer; Processing a bracket receiving groove on the surface layer by CNC, and exposing the isolation layer at the bottom of the bracket receiving groove; The isolation layer is removed to expose the designated area through the bracket receiving slot.

[0005] The present application also discloses a bracket protective shell, which is characterized by comprising: A back plate comprising a base layer and a surface layer, wherein one surface of the base layer has a designated area, the surface layer is connected to the surface of the base layer having the designated area, the surface layer is provided with a bracket receiving groove at a position corresponding to the designated area, the designated area is exposed at the bottom of the bracket receiving groove, and the surface of the designated area is smooth; The bracket is rotatably connected to the back plate, and the bracket can be selectively received in the bracket receiving groove or separated from the bracket receiving groove.

[0006] Compared with the prior art, this application has at least the following beneficial effects: The present application discloses a method for manufacturing a bracket protective case and a back panel of the bracket protective case. The back panel is stacked by a base layer and a surface layer, and connected by a plate composite process. When the bracket storage groove is processed by CNC, only the surface layer is cut off, and the base layer is protected by an isolation layer from being processed. After removing the isolation layer, the designated area of ​​the base layer is exposed. Since the tool does not contact the surface of the designated area of ​​the base layer, the surface of the exposed designated area of ​​the base layer is smooth, and there is no cutting mark. Therefore, in the present application scheme, the bottom of the bracket storage groove does not require an additional mylar sheet, which can ensure the neatness of the product, solve the risk of the mylar sheet falling off, and improve the user experience.

DETAILED DESCRIPTION

[0009] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

For example, the term "on" may also be used to express a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0012] Furthermore, the terms "provided with" and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0013] Furthermore, the terms "first," "second," and the like are primarily used to distinguish different devices, elements, or components (which may or may not be the same in type and configuration) and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0014] Protective cases are used as accessories for electronic devices and can provide all-round protection for electronic devices. With the continuous development of electronic devices, the functions brought by electronic devices are becoming more and more diversified. In application scenarios such as watching videos, office writing, and games, compared to placing electronic devices flat on the desktop for use, users will prefer to use electronic devices at a suitable angle through a bracket. Therefore, a bracket is usually set on the protective case to solve the above problem.

[0015] As a portable accessory, the bracket on a protective case should generally not affect the user experience. For example, if the bracket is directly protruding from the case, when the user is using the phone, the bracket protruding from the surface of the case can easily cause problems such as uncomfortable grip, uneven placement of the phone on the table, and the bracket easily scratching other objects. Therefore, it is usually necessary to create a groove on the surface of the protective case to accommodate the bracket. In existing processes, the groove is machined using a CNC (numerical control) machine. Since the groove is milled on the surface of the protective case (usually made of PC) by a tool, the bottom of the groove will have a cutting edge. For aesthetic reasons and to prevent scratches caused by friction between the bracket and the groove, a layer of Mylar sheet is attached to the bottom of the groove to cover the edge. However, the added Mylar sheet makes the product look awkward, and the attached Mylar sheet is prone to falling off after a long period of use, affecting the user experience.

[0016] In order to solve the above technical problems, the present application provides a method for manufacturing a bracket protective case and a back panel of the bracket protective case. The back panel is stacked by a base layer and a surface layer and connected through a plate composite process. When the bracket storage groove is processed by CNC, only the surface layer is cut off, and the base layer is protected from being processed by an isolation layer. After removing the isolation layer, the designated area of ​​the base layer is exposed. Since the tool does not contact the surface of the designated area of ​​the base layer, the surface of the exposed designated area of ​​the base layer is smooth, and there is no cutting mark. Therefore, in the solution of the present application, the bottom of the bracket storage groove does not require an additional mylar sheet, which can ensure the neatness of the product, and solves the risk of the mylar sheet falling off, thereby improving the user experience.

[0017] The technical solution of the present application will be further described below with reference to the embodiments and drawings.

[0018] See Figure 1 The present application provides a method for manufacturing a back plate of a bracket protective shell, comprising the following steps: S10: taking a layer of plate as a base layer, and providing an isolation layer in a designated area on one surface of the base layer; S20: taking another layer of plate as the surface layer and covering the side of the base layer provided with the isolation layer, and compounding the base layer and the surface layer; S30: A bracket receiving groove is processed on the surface by CNC, and an isolation layer is exposed at the bottom of the bracket receiving groove; S40: removing the isolation layer to expose the designated area through the bracket receiving groove.

[0019] The CNC-machined area corresponds to the surface layer and the isolation layer, which is the area where the bracket receiving slot 11 is located. In this embodiment, the CNC machining tool has a feed rate of β = 1.8 mm / s, meaning the tool moves and cuts 1.8 mm per second. At the same time, during machining, the CNC machining tool cuts the surface layer to a depth equal to the thickness of the surface layer. This means that CNC machining only targets the surface layer, and the CNC machining tool does not contact the isolation layer or the base layer. Even if there is a slight machining error, the isolation layer protects the base layer from being machined, thus leaving no traces of the tool on the surface of the designated area of ​​the base layer. When processing the surface layer, a tool with a diameter of 2.0mm and a length of 4.0mm is first used for processing. The surface of the tool is hardened (for example, by carbonization). After a certain period of processing, when the tool is very close to the isolation layer, for example, when the surface thickness is 1.5mm and the tool processes 1.4mm, and the distance from the isolation layer is only 0.1mm, it is necessary to replace the tool and use a finer tool for final processing. For example, the diameter of the replaced tool is 1.45mm and the length is 2.0mm. The finer the tool, the easier it is to control the processing accuracy and ensure that the tool does not damage the base layer. After processing is completed, the isolation layer will be exposed through the bracket storage slot 11. Finally, the isolation layer is removed, so that the designated area is exposed through the bracket storage slot 11, and the back plate of the bracket protective shell is obtained. The surface of the designated area of ​​the base layer is the bottom of the bracket storage slot 11, so the surface of the bottom of the bracket storage slot 11 is smooth and has no lines. Therefore, there is no need to stick additional Mylar sheets for covering, which ensures the neatness of the product and solves the risk of Mylar sheets falling off, thereby improving the user experience.

[0020] CNC machining is performed using a numerically controlled (CNC) machine tool, an automated machine tool equipped with a program-controlled system. This control system logically processes programs specified by control codes or other symbolic instructions, decodes them, and transmits them as coded digital representations via information carriers to the CNC device. After processing, the CNC device issues various control signals, controlling the machine's movements and automatically producing parts to the shape and dimensions specified in the drawings. CNC machine tools effectively address the challenges of machining complex, precise, small-batch, and high-variety parts. They are flexible, high-performance automated machines that represent the development direction of modern machine tool control technology and are typical mechatronic products. This ensures that the cutting tool does not damage the surfaces of the insulating layer and substrate during machining.

[0021] In some embodiments, see Figure 2 , step S10 includes the following sub-steps: S11: Covering one surface of the base layer with a release film; S12: cutting the release film along a boundary line between the designated area and the other areas by laser, so as to separate the release film into a first release film on a surface of the designated area and a second release film on a surface of the other areas; S13: The second release film is removed, and the remaining first release film is the isolation layer.

[0022] See Figure 5-Figure 8 , Figure 5-Figure 8 The whole process was demonstrated.

[0023] like Figure 5 As shown, the release film 14 is first applied to the surface of the base layer 13. At this point, the release film 14 is intact and covers the entire surface of the base layer 13. A film laminating jig is required to apply the release film 14. After the release film 14 and the surface of the base layer 13 are attached, bubbles may exist between the two. The jig can be used to exhaust the air and ensure a tight fit between the two. In other embodiments, the release film 14 can also cover only a designated area and a portion of the surrounding area, or it can cover only a designated area rather than the entire surface of the base layer 13.

[0024] like Figure 6As shown, the release film 14 covers the designated area and other areas around it. Along the dividing line between the designated area and other areas, the release film 14 is cut by laser to divide the release film 14 into a first release film 14a and a second release film 14b. The shape of the designated area can be understood as the shape of the bracket receiving groove 11. In the illustrated embodiment, the bracket receiving groove 11 is annular, so the shape of the first release film 14a after cutting is also annular. When cutting the release film 14, because the thickness of the release film 14 is relatively thin, only low-power laser cutting equipment can be used for cutting, such as a laser equipment with a power of 5-10W, to ensure that the edges of the release film 14 at the cut will not be burned, curled, etc. If the edges of the release film 14 are burned or curled, a gap will appear when the base layer 13 and the surface layer 12 are compounded, resulting in the two being unable to be compounded into a whole, and the subsequent product manufacturing process.

[0025] like Figure 7 As shown, the second release film 14b is removed, leaving only the first release film 14a. This prevents the second release film 14b from interfering with the lamination of the base layer 13 and the surface layer 12. The first release film 14a, on the one hand, isolates the base layer 13 and the surface layer 12 corresponding to the position of the first release film 14a, preventing that portion from laminating with other parts. On the other hand, during CNC machining, the first release film 14a also prevents the surface of the base layer 13 from being scratched by the tool. Covering the entire surface of the base layer 13 with release film 14, leaving only the first release film 14a, and removing the second release film 14b is done because this approach reduces labor and manufacturing costs compared to applying release film 14 only to designated areas. Applying release film 14 to designated areas is difficult due to the small size of the designated area and the high demands on production process and precision, which significantly affects product yield.

[0026] like Figure 8 As shown, after the first release film 14a is exposed through the bottom of the bracket receiving slot 11, the first release film 14a only needs to be torn off, and the designated area of ​​the base layer 13 can be exposed through the bracket receiving slot 11. In this embodiment, the adhesion between the first release film 14a and the base layer 13 is relatively weak, so the first release film 14a can be removed simply by tearing. Because the surface of the base layer 13 is smooth and has not been processed by CNC tools, the surface of the designated area of ​​the base layer 13 exposed through the bracket receiving slot 11 is smooth. In other words, the surface of the bottom of the bracket receiving slot 11 is smooth, and no additional mylar is required.

[0027] In some embodiments, see Figure 3 , step S10 includes the following sub-steps: S11: Covering one surface of the base layer with an appearance layer, where the appearance layer is used to achieve at least one appearance effect of the shell including color, texture, pattern, or highlight; S12: Cutting the appearance layer by laser along the boundary line between the designated area and other areas to divide the appearance layer into a first appearance layer on the surface of the designated area and a second appearance layer on the surface of the other areas, wherein the first appearance layer is the isolation layer.

[0028] See Figures 9-12 , Figures 9-12 The whole process was demonstrated.

[0029] like Figure 9 As shown, the exterior layer 15 is used to achieve at least one of the following effects: color, texture, pattern, or highlight. That is, by applying one or any combination of color, texture, pattern, or highlight to the exterior layer 15, and then configuring the surface layer 12 to be a transparent material (transparent materials in this application include fully transparent materials and semi-transparent materials, as long as the exterior layer 15 can be seen through), the effect applied to the exterior layer 15 can be seen through the surface layer 12. By covering the entire surface of the base layer 13 with the exterior layer 15, the color, texture, pattern, or highlight effects of the housing can be maximized. In other embodiments, the exterior layer 15 can be provided only in designated locations. In such embodiments, the exterior layer 15 is also required in designated areas of the base layer 13 so that it can function as a barrier.

[0030] like Figure 10 As shown, similar to the steps in the method for installing the release film 14, this embodiment also requires laser cutting of the exterior layer 15 along the boundary between the designated area and other areas, thereby separating the exterior layer 15 into a first exterior layer 15a on the surface of the designated area and a second exterior layer 15b on the surface of other areas. In this embodiment, the second exterior layer 15b does not need to be removed but remains on the backing plate. Therefore, the segmentation ensures that the removal of the first exterior layer 15a does not affect the second exterior layer 15b. In this embodiment, due to the particle size of the pigment raw material in the exterior layer 15, the thickness of the exterior layer is greater than that of the release film 14 in the previous embodiment, necessitating a higher power laser cutting equipment.

[0031] like Figure 11 FIG. 1 is a schematic diagram of the back panel structure after the base layer 13 and the surface layer 12 are combined, but before the first exterior layer 15a is removed. In this state, the first exterior layer 15a is exposed through the bracket receiving slot 11, while the second exterior layer 15b is visible through the surface layer 12.

[0032] like Figure 12 Figure 1 shows the structure of the back panel after the first exterior layer 15a has been removed. In this embodiment, the exterior layer 15a is applied to the surface of the designated area by spraying, electroplating, or printing. Therefore, the first exterior layer 15a is firmly bonded to the base layer 13 and cannot be removed manually. In this case, laser treatment or solvent dissolution can effectively remove the first exterior layer 15a. These methods ensure clean removal of the first exterior layer 15a without damaging the base layer 13. After removal, the designated area of ​​the base layer 13 is exposed through the bracket receiving slot 11. With solvent dissolution, an organic solvent (such as banana oil) is dripped onto the bottom of the bracket receiving slot 11. The organic solvent dissolves the first exterior layer 15a, exposing the designated area of ​​the base layer 13. Because the exterior layer 15 is printed using different inks depending on the pattern, texture, and other effects, different solvent ratios are required for each pattern to achieve optimal dissolution.

[0033] Banana oil, also known as thinner water or pear oil, is a colorless, transparent liquid composed of a mixture of various organic solvents. Its name stems from the inclusion of isoamyl acetate (which has a banana-like odor) in its early formulations. Its main components typically include ethyl acetate, toluene, acetone, and ethanol, with the proportions varying depending on the intended use. In common industrial products, esters comprise 30%-50%, while aromatic hydrocarbons account for 20%-40%. As a typical volatile mixed solvent, it is widely used in diluting nitrocellulose lacquer, cleaning oil stains, and in chemical synthesis.

[0034] Banana oil is a highly flammable, volatile mixed solvent with a density typically ranging from 0.86-0.92 g / cm³. It has a wide boiling point range (70-140°C) and a flash point as low as -4°C to 21°C. It can easily ignite or explode when exposed to open flames or high temperatures. Its core characteristic lies in its strong dissolving power, rapidly breaking down substances such as grease, resins, and nitrocellulose. It is miscible with most organic solvents (such as acetone and ethanol), but its solubility in water is extremely low. Compared to the previous embodiment, this embodiment replaces the release film 14 with an exterior layer 15 as the isolation layer. Firstly, the exterior layer 15 does not affect the lamination of the base layer 13 and the surface layer 12, eliminating the need to remove the second exterior layer 15b from other surface areas, reducing process steps and material waste. Secondly, the exterior layer 15, sandwiched between the base layer 13 and the surface layer 12, can achieve at least one of the following appearance effects: color, texture, pattern, or highlight, thereby enhancing the product's aesthetics.

[0035] In some embodiments, see Figure 6 Step S20: Compounding the base layer and the surface layer, including: S21: Apply photosensitive glue to the surface of the base layer on the side where the isolation layer is provided; S22: Covering the surface layer on the side of the base layer brushed with the photosensitive glue, and sending the surface layer into a bonding machine for lamination.

[0036] The bonding machine can combine the base layer and the surface layer into a single unit, enhancing the integrity of the back panel of the protective case and facilitating the connection between the back panel and the frame of the protective case. In this embodiment, the bonding machine uses a UV curing machine. Ultraviolet light is irradiated on a special glue (i.e., photosensitive glue) to cause the glue to polymerize and solidify, thereby bonding the base layer and the surface layer coated with the photosensitive glue into a single unit. In other embodiments, other methods can be used, as long as the base layer and the surface layer are connected as a single unit.

[0037] Continue reading Figure 11 The present application also provides a bracket protective case, which includes a back plate 10 and a bracket (not shown). The bracket is rotatably connected to the back plate 10. The bracket can be selectively stored in the bracket storage groove 11 or separated from the bracket storage groove 11, that is, rotated out of the bracket storage groove 11 to support the protective case. The back plate 10 includes a base layer 13 and a surface layer 12 (see Figure 5 ), one of the surfaces of the base layer 13 has a designated area, the surface layer 12 is connected to the surface of the base layer 13 with the designated area, and the surface layer 12 is provided with a bracket receiving groove 11 at a position corresponding to the designated area, wherein the bracket receiving groove 11 penetrates the surface layer 12 along the thickness direction of the surface layer 12, so that the designated area is exposed to the bottom of the bracket receiving groove 11, that is, the designated area can be exposed through the bracket receiving groove 11 and can be seen by the user, and the designated area just forms the bottom of the bracket receiving groove 11. The surface of the designated area is smooth, so there is no need to stick a mylar on the surface of the designated area, which can ensure the neatness of the product, solve the risk of the mylar falling off, and improve the user experience.

[0038] It is understood that the backplane in this embodiment can be manufactured using the backplane manufacturing method described in the above embodiment. The surface layer 12 is laminated on the outer surface of the base layer 13, the inner surface of the base layer 13 being the surface facing the electronic device. A through hole is machined through the surface layer 12 by CNC machining along the thickness direction of the surface layer. When the base layer 13 is connected to the surface layer 12, the base layer 13 blocks the opening of the through hole. The designated area of ​​the base layer 13 and the through hole together form the bracket storage slot 11.

[0039] In some embodiments, see Figure 12The backplane 10 also includes an exterior layer 15, which is stacked between the base layer 13 and the surface layer 12. The exterior layer 15 is used to achieve at least one of the following effects: color, texture, pattern, or highlight. That is, by applying one or any combination of color, texture, pattern, or highlight to the exterior layer 15, and then configuring the surface layer 12 to be a transparent material (the transparent material referred to in this application includes materials with fully transparent effects and semi-transparent effects, etc., as long as the exterior layer 15 can be visible through it), the effect applied to the exterior layer 15 can be visible through the surface layer 12. In other embodiments, the base layer 13 can also be configured to be a transparent material, allowing the exterior layer 15 to be visible from both sides. Furthermore, the thickness of the exterior layer 15 can be controlled within a range of 0.02 mm to 0.05 mm, ensuring that the exterior layer 15 does not significantly affect the overall thickness of the backplane.

[0040] In some embodiments, the exterior layer 15 does not cover the portion of the base layer 13 exposed through the through-holes. When the exterior layer 15 is exposed on the outer surface, it is susceptible to oxidation, causing it to peel and discolor. Therefore, during the manufacturing process of the backplane 10, the exterior layer 15 is removed from the portion of the base layer 13 that is exposed, effectively preventing problems caused by the exposed portion. Furthermore, because the bracket receiving slot 11 occupies a relatively small area, the missing portion of the exterior layer does not significantly affect the overall appearance.

[0041] In some embodiments, the thickness of the base layer 13 is less than the thickness of the surface layer 12. Since it is necessary to open a bracket receiving groove 11 on the surface layer 12 to accommodate the bracket, there are certain requirements for the thickness of the surface layer. If the thickness of the surface layer 12 is small, the bracket receiving groove 11 may not be able to completely receive the bracket. When the bracket is received, part of the bracket is still protruding from the surface of the back plate 10, which produces a bad user experience. At the same time, in order to make the overall thickness of the back plate 10 thinner, if the thickness of the surface layer 12 cannot be reduced, the thickness of the base layer 13 can be reduced so that the thickness of the base layer 13 is less than the thickness of the surface layer 12, thereby effectively reducing the overall thickness of the back plate 10. Furthermore, the thickness range of the base layer 13 is set to 0.8mm~1.2mm to ensure that the base layer 13 is not too thin. If the base layer 13 is too thin, the bottom of the bracket receiving groove 11 will be easily broken. At the same time, the thickness range of the surface layer is set to 1.3mm~2.0mm. While meeting the requirements of fully storing the bracket, the overall thickness of the back panel is controlled at about 3mm to ensure that the overall protective case is not too thick.

[0042] In some embodiments, the base layer 13 and the surface layer 12 are connected by adhesive. In this embodiment, the bonding is achieved by applying photosensitive adhesive between the base layer 13 and the surface layer 12, and then placing them in a bonding machine for lamination. The bonding machine uses a UV curing machine. Ultraviolet light is irradiated on the special adhesive (i.e., photosensitive adhesive), causing the adhesive to polymerize and solidify, thereby laminating the base layer 13 and the surface layer 12 coated with the photosensitive adhesive into a single unit.
