[0027] The specific implementation of the present disclosure is described in detail below with reference to the accompanying drawings.

[0028] Figure 1The exploded schematic diagram of the electronic device of some embodiments of the present disclosure is shown. In this embodiment, the electronic device can be a mobile phone, but in other embodiments, the electronic device can be other electronic devices such as an earphone box, a watch, a tablet computer, etc. In this embodiment, the electronic device includes a transparent part 10, a decorative part 20 stacked with the transparent part 10, and a metal part 30 for surrounding the decorative part 20 together with the transparent part 10. The transparent part 10 can be formed as a plate-like element composed of a transparent material, or it can be at least partially composed of a transparent material, and its shape is roughly rectangular. The metal part 30 can be formed as a rectangular metal frame arranged around the periphery of the decorative plate. The transparent part 10 is stacked with the decorative part 20 along the assembly direction, and the transparent part 10 defines a corresponding light-transmitting area inside the electronic device. In this embodiment, the light-transmitting area can correspond to the decorative part 20, so that the decorative part 20 is visible from the outside of the electronic device through the transparent part 10. The metal part 30 may be partially covered by the decorative part 20 in the light-transmitting area, and a covering layer 31 may be provided in at least a portion of the area of ​​the metal part 30 not covered by the decorative part 20 . The covering layer 31 may be provided on the surface of the side facing the transparent part 10 adjacent to the decorative part 20 .

[0029] Here, for ease of understanding, the assembly direction of the transparent part 10 and the decorative part 20 is defined as the vertical direction in this article, and the position of the transparent part 10 is the vertical upper side, and the position of the decorative part 20 is the vertical lower side. The description of the positions of other components is based on this.

[0030] See also Figure 2 , Figure 2 A partial cross-sectional view of an electronic device of some embodiments of the present disclosure is shown. A frame 40 is provided on the circumferential outer side of the metal part 30, and the metal part 30 and the frame 40 are relatively fixed by shape matching. In this embodiment, the frame 40 can be a plastic shell made of a material such as polycarbonate, and the metal part 30 can be made of a metal material such as aluminum or aluminum alloy. The frame 40 can be integrally formed with the metal part 30 and formed by CNC processing. The circumferential outer side of the metal part 30 is in shape matching with the frame 40. For example, Figure 2As shown in , a fixing edge 33 protruding downward in the vertical direction is provided at the lower part of the circumferential outer side of the metal part 30, and a fixing recess 35 protruding downward in the vertical direction is provided at the upper part, and the fixing edge 33 extends into a corresponding recess 45 formed on the frame 40, and the fixing recess 35 is matched in shape with the lateral protrusion 43 protruding from the upper part of the frame 40. In the case where the metal part 30 and the frame 40 are formed by integral molding, the setting of the fixing edge 33 and the fixing recess 35 can increase the contact area with the material of the frame 40, increase the connection force between the materials, and at the same time form a shape match to further enhance the structural strength. In this embodiment, the metal part 30 is used to enhance the overall structural strength of the electronic device, and the frame 40 is used to wrap the metal part 30 from the circumferential outer side, so as to be used as a material in direct contact with the user to enhance the user experience.

[0031] The upper part of the frame 40 is fixedly connected to the transparent member 10 by bonding or other means. In this embodiment, the outer periphery of the transparent member 10 is provided with a downwardly protruding descending edge 15, and an adhesive layer 60 is provided between the lower surface of the descending edge 15 and the upper surface of the frame 40. The upper side of the adhesive layer 60 is bonded to the surface of the vertical lower side of the descending edge 15, and the lower side is bonded to the upper surface of the transverse protrusion 43 of the frame 40. The adhesive layer 60 can enhance the sealing effect while connecting and fixing the transparent member 10 and the frame 40. The decorative member 20 can be arranged on the circumferential inner side of the metal member 30 and the frame 40, and its outer peripheral part is partially overlapped on the upper surface of the metal member 30 along the stacking direction to partially cover the surface of the metal member 30. A gap 50 is also provided between the outer peripheral edge of the decorative member 20 and the circumferential inner edge of the transverse protrusion 43 of the frame 40. The covering layer 31 is arranged on the upper surface of the metal member 30, and it at least partially overlaps with the gap 50 along the stacking direction. It is understandable that due to the highly integrated and miniaturized components of electronic products, it is difficult to ensure that the matching tolerances between the components are completely appropriate during the manufacturing process of electronic equipment. If the assembly gap is preset, assembly interference caused by the tolerance can be avoided. However, the metal part 30 may be exposed through the transparent part 10 at the assembly gap, making its surface defects such as metal oxidation and processing marks very obvious, and the exposure of the metal surface may also cause the problem of undesirable reflection. Figure 5 , Figure 5 A partial effect diagram of an electronic device in some embodiments of the present disclosure without a covering layer is shown. The covering layer 31 here covers the exposed surface of the metal part 30 at the gap 50, thereby eliminating the defects of the exposed metal surface and preventing the light inside and outside the electronic device from irradiating the metal part surface and causing reflection.

[0032] It will be understood by those skilled in the art that, although a design including a metal part 30 and a non-metallic frame 40 is described in this embodiment, the present disclosure is not limited in terms of the specific structure of the metal part 30. First, the metal part 30 may also be configured to have a straight outer peripheral surface, which is connected to the outer frame by an integral molding method, and relies on the material connection force between the two to maintain a fixed connection with each other. Alternatively, the metal part may also partially protrude from the outer surface of the frame along the circumferential direction, or the outer surface of the metal part may be directly exposed, replacing the frame for direct contact with the user. In the above alternative embodiments, it is only necessary to ensure that the metal part and the frame are fixedly connected to other elements, such as a transparent part.

[0033] In this embodiment, a refractive surface 11 may be provided on the circumferential inner side of the descending edge 15 of the outer peripheral portion of the transparent member 10. The refractive surface 11 may be, for example, a combined inclined curved surface that starts from the edge of the vertical lower surface of the descending edge 15 close to the inner side of the electronic device, gradually rises and extends obliquely toward the circumferential inner side of the descending edge 15, and bends to transition to the horizontal bottom surface of the transparent member 10. The refractive surface 11 at least partially overlaps with the gap 50 in the vertical direction, so that the projection of the metal member 30 at the gap 50 to the outside of the electronic device can be refracted and blurred by refraction. After refraction by the refractive surface 11, even if the user directly looks at the light-transmitting area of ​​the electronic device through the transparent member 10, the defects on the surface of the metal member 30 and the defects and color difference between the covering layer 31 and other components can be hidden. It can be understood by those skilled in the art that the refractive surface in this embodiment is composed of an inclined surface and an arc surface, but the present disclosure does not limit the specific composition and form of the refractive surface. For example, a refractive surface with a multi-step or wavy cross section can be provided to enhance the refractive effect on the surface of the metal part by repeatedly reflecting and refracting the light. In this embodiment, the outer peripheral portion of the transparent part 10 is also provided to include an arc-shaped curved surface 17 to enhance the refractive effect of the transparent part on the inner light. In addition, a rough matte surface can also be provided at the position of the transparent part corresponding to the metal surface to form an effect similar to frosted glass, so as to blur the image of the exposed metal surface when observed from the outside of the transparent part 10 by diffuse reflection, thereby making the reflected light less obvious and difficult for the user to detect.

[0034] In this embodiment, the covering layer 31 can be a laser engraving layer formed on the upper surface of the metal part 30 by a laser laser engraving process, and the distance between the outer edge of the laser engraving layer and the lateral protrusion 43 of the frame 40 is at least 0.25 mm, so as to prevent the frame 40 from being damaged during the laser laser engraving process. It is understandable that the covering layer 31 can also be formed by other surface treatment processes, such as common oxidation blueing treatment, etc., and the specific surface treatment method can be adjusted according to the actual material used and the required color effect. In some embodiments, the covering layer 31 can also be set as a diffuse reflection layer, that is, a surface structure capable of diffusely reflecting light is formed by surface treatment such as frosting, so as to achieve the purpose of eliminating metal surface defects by reducing the reflection of the metal surface at that place. It is understandable that the diffuse reflection layer can also be used in combination with the laser engraving layer, that is, the diffuse reflection layer is formed by frosting and other processes, and then laser engraving is performed on the diffuse reflection layer to form a laser engraving layer. After surface treatment such as frosting, the metal surface becomes rough, which also improves the adhesion effect of the laser engraving layer or other covering layers produced by surface treatment.

[0035] See also Figure 3 , Figure 3 A schematic diagram of a decorative part of an electronic device of some embodiments of the present disclosure is shown. The decorative part 20 includes a main body that is roughly in the shape of a rectangular plate, and a plurality of decorative elements are arranged on the surface of the side facing the transparent part 10. On the outer peripheral side of the decorative part 20 of the electronic device, a plurality of metal screws 21 for fixing or electronic components with metal parts exposed to the light-transmitting area corresponding to the transparent part 10 may be arranged, such as a camera module 29, an FPC cable, and other similar components including metal parts. For the surfaces of the metal parts of these other components, since they may also have surface defects or cause reflections, structures such as laser carving layers or diffuse reflection layers may also be provided to remove defects and de-reflection. For the metal parts of such components, since they are located in different positions, when applying a covering layer to them, they can be adjusted with reference to the color of the adjacent decorative parts or outer frames to avoid the occurrence of color incompatibility with the surrounding components.

[0036] The laser engraving treatment of the metal surface of the above-mentioned metal part 30 and the components is aimed at eliminating the exposed surface defects. To this end, the laser engraving target can be set to process the color difference value ΔE of each part of its surface to less than 4. Here, ΔE represents the color difference value measured by the colorimeter and expressed by the human eye in the uniform color perception space according to the CIE1976Lab standard. In order to further make the color of the metal surface consistent with that of other parts of the electronic device, the color depth can be adapted to other adjacent components by adjusting the corresponding parameters in the laser engraving process, such as laser power. For example, the color of the laser engraving layer near the decorative part 20 can be set to a color difference value ΔE less than 4 between the decorative part 20 or the metal part 30. It should be noted that the purpose of setting the color difference value here to less than 4 is to make the color of the exposed surface uniform and avoid the generation of color difference that can be clearly perceived by the naked eye. However, the obviousness of the color difference of different color types is a relatively subjective issue, which cannot be completely quantified according to the standard, so it can also be further adjusted according to the actual visual effect. In the case where the decorative part 20 includes decorative elements of multiple different colors, the color difference value ΔE between the decorative elements of multiple different colors can be greater than 10. In this embodiment, the color difference between different decorative elements is set to be greater than 10 in order to form a sense of hierarchy visually, so that each decorative element can be regarded as a plurality of different components. The laser engraving layer portion adjacent to the corresponding decorative element can also adjust the color of the laser engraving layer to match the corresponding decorative element according to the above color difference standard. For example, in this embodiment, the decorative part 20 can be composed of a plurality of different decorative elements. For example, the upper surface of the decorative part 20 can be provided with decorative elements such as a wiring 25, an annular decorative part 23, and a decorative lamp 27, wherein the color difference value ΔE between each decorative element in the luminous or non-luminous state can also be greater than 10. In addition, according to actual needs, the metal surface of the metal part can also be considered as a decorative element. In this case, a covering layer of different colors can also be applied to the corresponding metal part separately without considering the color difference between it and the adjacent decorative element.

[0037] In addition, the above-mentioned various decorative elements can correspond to the positions of corresponding functional components inside the electronic device. For example, the interior of the electronic device may include functional components such as coils, charging components, and charging interfaces. Such functional components are electrically connected to the control module of the electronic device to perform their corresponding functions such as charging and communication. By making the annular decorative member 23 correspond to the position of the coil inside the electronic device, making the flat cable 25 correspond to the position of the charging interface, etc., and covering the corresponding functional components one by one, the connection between the decorative element and its internal functional original can be made more intuitive. For example, by making the flat cable 25 correspond to the charging interface in position and connecting both to the control module at the same time, the charging status can be intuitively displayed through the light and dark conditions of the flat cable 25 when the mobile phone is charging. By matching the setting of the above-mentioned flat cable 25 with the setting of the decorative light 27 and the annular decorative member 23, the user can directly understand the charging status or communication status, etc. through the status of different decorative elements at different positions without confusion. In another embodiment, the various functional components may include an outer surface exposed in the light-transmitting area. In this case, it is not necessary to set a decorative element corresponding to the functional component, but a texture or pattern can be directly formed on the exposed surface of the functional component so that the exposed part of the functional component constitutes a part of the decorative member.

[0038] It is understood by those skilled in the art that, although the above embodiments describe an embodiment in which a laser engraving layer is used as a covering layer, the present disclosure does not limit the specific formation method of the covering layer. Figure 2The filling material such as UV glue filled in the gap 50 shown, wherein the filling material can be a transparent colloid material. By partially or completely filling the gap near the metal part with the filling material, the reflection on the surface of the metal part can be effectively reduced by refraction with the help of the difference in its own refractive index. In addition, the surface of the filling material facing the transparent part can be formed into an arc or an inclined surface, so as to reduce the reflection on the surface of the metal part by refraction or reflection by matching its own refractive index with the angle of its surface. And due to the filler, the area will not accumulate dust. The filling material can also be a colored material, so that it can directly cover or reduce the reflection on the surface of the metal part. In addition, a fluorescent material can also be used to form a covering layer, for example, by covering a fluorescent layer containing fluorescent powder on the surface of the metal part near the decorative part to form a covering layer. In this embodiment, a gap for accommodating the fluorescent layer can be provided between the metal part and the decorative part to ensure that the fluorescent layer is stably maintained on the metal part and will not be damaged. In addition, the color and luminous brightness of the fluorescent layer can be adjusted by adjusting the composition of the fluorescent powder, so that the color difference value ΔE between the fluorescent layer and the decorative part near the two can be less than 4. By providing a fluorescent layer, the reflection of the metal surface can be reduced while increasing the recognition of the electronic device under low light conditions. In addition, similar fluorescent materials can be provided on the decorative part near the metal part to make the edge of the covering layer and the decorative part visually unified, further improving the aesthetics of the product.

[0039] One or more of the decorative parts may also be directly provided with a fluorescent layer. Then, in a dark environment, the exposed metal parts will be more difficult to become the main focus of the user due to the fluorescent effect.

[0040] Although the multiple embodiments described above in conjunction with the accompanying drawings show a mobile phone with a roughly rectangular plate-shaped appearance, the present disclosure is not limited to the specific appearance and type of the electronic device. For example, the electronic device described in the present disclosure may also be an earphone box with a transparent shell, or a wearable device such as a watch or earphone. Figure 4 , Figure 4 An exploded schematic diagram of an electronic device according to some embodiments of the present disclosure is shown. Figure 4 The earphone box 100 shown in the figure comprises a transparent part 110, a metal part 120 and a decorative part 130, wherein the metal part 120 and the decorative part 130 are fixed relative to each other and are arranged together on the inner side of the substantially cylindrical transparent part 110. The metal part 120 and the decorative part 130 are rotatably connected to the transparent part 110, and when the earphone box 100 is in the closed box state, the transparent part 110 can be rotated to cover the metal part 120 and the decorative part 130. By arranging a covering layer at a position of the metal part 120 adjacent to the decorative part 130, the reflection on the surface of the metal part can be effectively reduced. As for other corresponding electronic devices, it is only necessary to change the shapes of the transparent part, the decorative part and the metal part on the basis of the above description.

[0041] By providing a covering layer in the transparent area of ​​the electronic device according to the present disclosure, the surface defects of the metal components in the electronic device are eliminated, and the overall consistency is better. In particular, in the case where the decorative panel is embedded, the problem of protruding metal component defects in the transparent part of the shell is avoided. In addition, the wiring or other components may be provided with fluorescent materials on the surface to make the surface glow, thereby increasing the recognition of the electronic device in a low-light environment. In this case, when the electronic device is illuminated by an external light source, or when the internal decorative light source such as the decorative panel of the electronic device is illuminated, the covering layer can also prevent the surface of the metal component from having unexpected reflections, which may affect the actual observation effect and cause misjudgment of functions or faults.

[0042] Although multiple embodiments of the present disclosure have been shown and described herein, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Those skilled in the art may think of many changes, modifications, and alternatives without departing from the thought and spirit of the present disclosure. It should be understood that in the process of practicing the present disclosure, various alternatives to the embodiments of the present disclosure described herein may be adopted.
