[0039] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0040] This application provides an electronic device, including but not limited to cellphones, notebook computers, tablet personal computers, personal digital assistants, wearable devices, or mobile devices.

[0041] refer to Figure 1 , Figure 2 and Figure 3 In some embodiments, a mobile phone is used as an example for illustration. It should be noted that in the figures of the embodiments of this application, the X-axis direction can be defined as the width direction of the electronic device 1, the Y-axis direction as the length direction of the electronic device 1, and the Z-axis direction as the thickness direction of the electronic device 1. More specifically, the positive direction of the X-axis can be defined as the direction from right to left on the display surface when the user uses the electronic device 1, the positive direction of the Y-axis can be defined as the direction from bottom to top on the display surface when the user uses the electronic device 1, and the positive direction of the Z-axis can be defined as the direction from the back of the electronic device 1 to the display surface.

[0042] like Figure 1, Figure 2 and Figure 3 As shown, the electronic device 1 provided in this application embodiment includes a housing 10, a main display module 20, a battery module 30, a camera module 40, a rear display module 50, and a rear cover assembly 60. The housing 10 can be used to provide positioning support and protection for the main display module 20, battery module 30, camera module 40, rear display module 50, and rear cover assembly 60.

[0043] The housing 10 includes a middle frame 11, with the main display module 20 and the rear cover assembly 60 located on opposite sides of the middle frame 11 and fixedly connected to it. Specifically, the main display module 20 and the rear cover assembly 60 can be fixedly connected to the middle frame 11 by dispensing, thereby improving the reliability and stability of the connection. In this embodiment, the main display module 20 and the rear cover assembly 60 are fixedly connected to opposite sides of the housing 10, and the main display module 20, the rear cover assembly 60, and the housing 10 together form an installation space. The installation space is used to accommodate and install electronic components such as the battery module 30, camera module 40, rear display module 50, and circuit board of the electronic device 1. Specifically, a first installation space can be formed between the middle frame 11 and the rear cover assembly 60, and at least some of the aforementioned electronic components can be disposed within the first installation space. A second installation space can be formed between the middle frame 11 and the main display module 20, and some of the aforementioned electronic components can be disposed within the second installation space. Understandably, the battery module 30 can provide power to the main display module 20, the camera module 40, and the rear display module 50.

[0044] The mid-frame 11 includes a border 12, which can be made of materials such as aluminum alloy, magnesium alloy, stainless steel, ceramic, glass, or plastic, but is not limited to these. Function buttons such as volume buttons and a screen-off button can be disposed on the border 12, and these function buttons are electrically connected to the processor of the electronic device 1. In an exemplary embodiment, the border 12 can be manufactured by at least one of the following methods: injection molding, compression molding, extrusion, forging, die casting, and computer numerical control (CNC) machine tool processing.

[0045] In this embodiment, the frame 12 may be made wholly or partially of a transparent material (not limited to glass, transparent plastic, etc.). By making the frame 12 of a transparent material, not only is processing and manufacturing convenient, but the electronic components inside the electronic device 1 can also be visualized.

[0046] The main display module 20 has display and touch functions, meaning that the electronic device 1 can be operated by clicking on the main display module 20. The main display module 20 may include structural layers such as a touch screen, a light-emitting layer, a backplane layer, and a substrate layer, the specific structure of which can be selected according to different products. In this embodiment, the main display module 20 can be a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED) display, an Active-Matrix Organic Light-Emitting Diode (AMOLED) display, a Flexible Light-Emitting Diode (FLED) display, or a Quantum Dot Light-Emitting Diode (QLED) display, etc. The main display module 20 can be used to display image information and provide an interactive interface for the user.

[0047] In this embodiment, the rear display module 50 may be a dot matrix screen, which is used to display functional image information to the user. The functional image information includes, but is not limited to, displaying time, date, preset patterns, logos, and other image information, to increase the functionality, visual appeal, and personalized design of the electronic device 1.

[0048] In this embodiment, the electronic device 1 may further include a circuit board located within the mounting space and fixedly mounted on the housing 10. The circuit board is electrically connected to the battery module 30, the main display module 20, the camera module 40, and the rear display module 50, respectively. The circuit board may also integrate electronic components such as the processor, storage unit, baseband chip, and power management unit of the electronic device 1. The processor controls the display of the main display module 20 and the rear display module 50, as well as the shooting of the camera module 40. The power management unit distributes the voltage provided by the battery module 30 to the various electronic components in the electronic device 1. The circuit board may be a printed circuit board (PCB), consisting of an insulating base plate, connecting wires, and pads for assembling and soldering electronic components, serving the dual function of conductive lines and an insulating base plate. The circuit board may be a single-sided board, a double-sided board, or a multi-layer board, which can replace complex wiring, enabling wiring and electrical connections or electrical insulation between various electronic components, and providing the required electrical characteristics.

[0049] In this embodiment, the electronic device 1 may further include at least one pressure-sensitive button 70, which is disposed on the back cover assembly 60 and near the edge of the back cover assembly 60. The pressure-sensitive button 70 is electrically connected to the circuit board and the rear display module 50, and can control the rear display module 50 to display corresponding image information, such as controlling the rear display module 50 to light up the screen; or, for example, pressing and holding the pressure-sensitive button 70 can turn off the screen of the rear display module 50; double-clicking the pressure-sensitive button 70 can adjust the display brightness of the rear display module 50 or change the display pattern. It is understood that the way the pressure-sensitive button 70 controls the rear display module 50 can be adjusted and preset according to specific needs, and this application does not specifically limit it in this regard.

[0050] In this embodiment, the back cover assembly 60 includes a transparent back cover 61, which is disposed opposite to the main display module 20 and detachably mounted on the housing 10. The back cover 61 includes a first surface and a second surface disposed opposite to each other. The first surface is the outer surface of the back cover 61, visible to the user, while the second surface is the inner surface of the back cover 61, facing the interior of the electronic device 1. The back cover 61 may be partially or completely transparent. Of course, in some other embodiments, the back cover 61 may also be opaque.

[0051] In this embodiment, the pressure-sensitive button 70 is disposed on the first surface of the back cover 61, and an opaque adhesive patch area is formed on the first surface. The user can perform input operation on the pressure-sensitive button 70 by pressing the opaque adhesive patch area.

[0052] Understandably, in order to prevent accidental operation when grabbing the electronic device 1, the pressure-sensitive button 70 is located on the first surface of the back cover 61 near the edge.

[0053] In this embodiment of the application, the back cover 61 may be the battery cover of the electronic device 1 made of a transparent material (such as glass, transparent plastic, etc.).

[0054] In one embodiment of this application, the back cover 61 and the frame 12 may be made entirely or partially of transparent materials (such as glass, transparent plastic, etc.). This not only facilitates processing and manufacturing, but also allows at least some electronic components of the electronic device 1, such as the camera module 40 and the rear display module 50, to be visualized through the transparent back cover 61. Users can see at least some electronic components and their arrangement on the back of the electronic device 1, which helps to improve the technological feel, personalization and overall aesthetics of the electronic device 1.

[0055] In this embodiment, after the back cover 61 is fixedly connected to the middle frame 11, the first surface of the back cover 61 is exposed so that the user can directly view the appearance of the back cover 61, thereby enhancing the appearance of the electronic device 1. Furthermore, the back cover 61 is made of glass, such as high-alumina silicon glass or nanocrystalline glass, which has characteristics such as high hardness, wear resistance, and scratch resistance. It is understood that the first surface (i.e., the appearance surface) of the back cover 61 is a relatively smooth surface to give the back cover 61 better appearance characteristics.

[0056] refer to Figure 4 In this embodiment, the middle frame 11 further includes a support module 80, which includes a first support 81. The first support 81 is disposed within the space enclosed by the frame 12, and the first support 81 is opposite to the back cover 61. The first support 81 can be a rectangular plate-shaped structural component, and the first support 81 can be detachably connected to the frame 12 by means of bonding, snap-fit ​​connection, threaded connection, bolt connection, etc. The first support 81 can be a metal part, such as aluminum alloy, or it can be a component made of metal and plastic materials. In an exemplary embodiment, the first support 81 can be integrally formed by at least one of injection molding, compression molding, extrusion, forging, die casting, and CNC machine tool processing.

[0057] The first bracket 81 also includes at least one clearance hole, the position of which corresponds to the position of the electronic component in the electronic device 1, and the electronic component can pass through the clearance hole. For example, the position of the clearance hole corresponds to the position of electronic components such as ribbon cables, coils, and functional components in the electronic device 1. Therefore, by providing clearance holes on the first bracket 81, interference with electronic components such as ribbon cables can be avoided when the first bracket 81 is pulled up and opened. For example, the first bracket 81 is prevented from being pulled and interfered with by ribbon cables and coils, so the first bracket 81 can be pulled up and opened smoothly and quickly.

[0058] In an exemplary embodiment, the first bracket 81 also has at least one mounting hole extending through the thickness of the first bracket 81. The mounting hole is used to mount and secure electronic components of the electronic device 1, such as a camera or flash. For example, a camera can pass through the mounting hole and abut against the wall of the hole, thereby being mounted and secured within the mounting hole. It is understood that the location and number of mounting holes are not limited to those shown in the figures, and can be adaptively adjusted according to the layout, arrangement, and number of electronic components in the electronic device; this application does not impose specific limitations in this regard.

[0059] refer to Figure 4In this embodiment, the first bracket 81 may further include a fixing member 811. The bracket module 80 also includes a second bracket 82, which at least partially overlaps with the first bracket 81 in the orthographic projection direction toward the middle frame 11 and is connected by the fixing member 811.

[0060] It is understandable that a portion of the second bracket 82 overlaps with a portion of the first bracket 81, wherein the end of the second bracket 82 near the first bracket 81 and the end of the first bracket 81 near the second bracket 82 overlap each other, which facilitates installation and improves the connection performance between the second bracket 82 and the first bracket 81.

[0061] In this embodiment, the second bracket 82 is used to fix some functional components, including but not limited to: light sensors, light arrays, flashlights, cameras, circuit boards, rear display modules, etc., which are not limited in this embodiment. For example, the second bracket 82 is detachably connected to the housing 10 via threaded components, such as bolts or screws. The second bracket 82 is used to protect related electronic components on the circuit board. For example, when the electronic device 1 is dropped or subjected to external impact, it can prevent the external force from directly acting on the circuit board, ensuring the connection stability of the electronic components on the circuit board. The second bracket 82 can be made entirely of metal, or it can be a component made of metal and plastic materials. In addition, by setting the second bracket 82, when some electronic components inside the housing 10 need to be modified or replaced, only the second bracket 82 needs to be disassembled, making maintenance quick and convenient, and improving the overall maintenance efficiency.

[0062] refer to Figure 4 In this embodiment of the application, the second bracket 82 is provided with a first groove 821 and a second groove 822. The first groove 821 can be used to install a light sensor and a flash, etc., and the second groove 822 can be used to install a rear display module, etc.

[0063] In this embodiment, the bracket module 80 further includes a decorative component 83, which includes multiple decorative elements 100. These decorative elements 100 are disposed on the surface of the first bracket 81 facing the rear cover 61 and correspond to the positions of electronic components such as ribbon cables, coils, processors, battery modules 30, circuit boards, and other functional components of the electronic device 1. The decorative elements 100 are used to conceal the electronic components and are visible through the transparent rear cover 61, which helps to improve the appearance and overall aesthetics of the electronic device 1. The decorative elements 100 can cover at least part of the clearance holes, mounting holes, receiving slots, or injection holes. Therefore, by combining the first bracket 81 with the decorative elements 100, the appearance performance of the first bracket 81 is further improved, achieving a structure that allows for flexible splicing and replacement of different appearance textures. Furthermore, the decorative element 100 can also provide users with labeled information about electronic components. Users can learn about the distribution of electronic components inside the electronic device 1 through the decorative element 100, allowing them to easily identify the component's installation location, name, and function, thus enhancing the information delivery of the electronic device 1. For example, if the decorative element 100, through the back cover 61, displays the label "coil," the user can immediately identify the electronic component as a coil, its installation location, and its function, significantly improving the technological feel and personalized design of the electronic device 1. Simultaneously, while allowing users to see the distribution of electronic components inside the electronic device 1, the first bracket 81 itself forms a decorative surface, ensuring the neat appearance of the internal components and enhancing the overall aesthetics and appearance of the electronic device 1.

[0064] It is understood that the decorative element 100 can be a decorative film, a decorative insert, etc. For example, the decorative element 100 can be a PET film with an appearance, an injection-molded part with an appearance texture, etc. The number of decorative elements 100 is at least one. Optionally, multiple decorative elements 100 are arranged at intervals. Optionally, multiple decorative elements 100 are arranged in an array.

[0065] It is understandable that by attaching multiple decorative pieces 100 to different positions of the first bracket 81, and by setting various decorative pieces 100, different appearance textures can be flexibly combined and replaced, thereby increasing the design space for freely changing the texture effect of the battery bracket, providing convenience for realizing diversified and personalized structural designs, and thus improving the user experience.

[0066] The following details a decorative element 100 in an embodiment of this application.

[0067] refer to Figure 5 and Figure 6The decorative element 100 includes a first portion 110, a second portion 120, and a third portion 130. At least a portion of the first portion 110 is light-transmitting, allowing a first light beam to pass through. The second portion 120 is fixedly connected to the first portion 110 and is opaque. The third portion 130 is fixedly connected to the second portion 120 and is light-transmitting, allowing a second light beam to pass through.

[0068] refer to Figure 7 and Figure 8 The first optical element 200 and the second optical element 300 are both disposed between the middle frame and the decorative element 100. The first optical element 200 and the second optical element 300 are respectively fixed on the first bracket 81 of the middle frame, for example, the first optical element 200 and the second optical element 300 are fixed in the first groove 821 of the second bracket 82. The first optical element 200 and the second optical element 300 are both opposite to the decorative element 100. The decorative element 100 is disposed between the middle frame and the back cover 61. At least a portion of the back cover 61 is light-transmitting, and the light-transmitting area of ​​the back cover 61 and the orthographic projection of the decorative element 100 onto the middle frame at least partially overlap.

[0069] The first optical element 200 is used to receive / emit the first light beam, and the second optical element 300 is used to receive / emit the second light beam. A first portion 110 is disposed on the side of the first optical element 200 away from the mid-frame, and the first portion 110 is located between the first optical element 200 and the light-transmitting area of ​​the rear cover 61. A third portion 130 is disposed on the side of the second optical element 300 away from the mid-frame, and the third portion 130 is located between the second optical element 300 and the light-transmitting area of ​​the rear cover 61.

[0070] The design scheme described in this embodiment allows external light beams to pass through the light-transmitting area of ​​the back cover 61 and the first portion 110 of the decorative element 100, and then be received by the first optical device 200. The light beam emitted by the first optical device 200 can then pass through the first portion 110 of the decorative element 100 and the light-transmitting area of ​​the back cover 61 to reach the outside. Similarly, external light beams can pass through the light-transmitting area of ​​the back cover 61 and the third portion 130 of the decorative element 100, and then be received by the second optical device 300. The light beam emitted by the second optical device 300 can then pass through the third portion 130 of the decorative element 100 and the light-transmitting area of ​​the back cover 61 to reach the outside.

[0071] In one specific embodiment, the first part 110 can be a light-transmitting plate made of plastic, and the first optical device 200 is a light sensor used to receive a first beam of ambient light. The second optical device 300 is an LED, including a flash or an array of lights, and is used to emit a second beam of light. The third part 130 can be a lens.

[0072] When the first optical device 200 is a light sensor, the controller 400 controls the brightness of the light-emitting device based on the brightness of the light beam received by the first optical device 200. The light-emitting device can be a main display module, and the controller 400 and the first optical device 200 are connected by a wiring harness. The wiring harness and the controller 400 can be shielded by the second part 120 of the decorative piece 100. It is understood that the controller 400 can also be integrated onto the circuit board of the electronic device, or the processor of the aforementioned electronic device can be used as the controller 400.

[0073] The controller 400 controls the brightness of the main display module based on the brightness of the ambient light received by the first optical device 200, which enables the brightness of the main display module to be adaptive, thereby improving user visual comfort, reducing eye fatigue, optimizing power consumption, extending the battery life of electronic devices, and enhancing the flexibility of usage scenarios.

[0074] It is understandable that the controller 400 can also control the brightness of the rear display module according to the brightness of the natural light received by the first optical device 200, so that the rear display module also has brightness adaptive performance. Its beneficial effects can be referred to the main display module, and will not be elaborated further.

[0075] In this embodiment, the second optical device 300 is a flash lamp, and the third part 130 is a Fresnel lens. Alternatively, the second optical device 300 is a display module, and the third part 130 is a lampshade with a light transmittance between 80% and 96%, such as 80%, 85%, 90%, 95%, or 96%, etc. Specifically, the display module can be the aforementioned rear display module.

[0076] In other embodiments, reference is made to Figure 9 The aforementioned decorative element 100 can directly form part of the back cover 61; in other words, a portion of the back cover 61 is the aforementioned decorative element 100. In this case, the remaining portion of the back cover 61 can be configured to be translucent or opaque as needed. Alternatively, refer to... Figure 10 A perforation 601 can be provided on the back cover 61, extending through the back cover 61 along its thickness direction. The decorative piece 100 passes through the perforation of the back cover 61 and extends to the side of the back cover 61 away from the first bracket 81. Alternatively, the decorative piece 100 can be fixedly snapped into the perforation of the back cover 61.

[0077] In this embodiment, one decorative element 100 can correspond to multiple optical devices, and the decorative element 100 can transmit light beams emitted or received by multiple optical devices. Compared to a solution where one decorative element 100 corresponds to one optical device, the technical solution provided in this embodiment can reduce the number of parts and improve the structural compactness and assembly convenience of electronic devices.

[0078] In this embodiment of the application, reference is made to Figure 11 and Figure 12 The first part 110 and / or the third part 130 include a body and an outer wall, the outer wall surrounding the outer periphery of the body and fixedly connected to the body; the body is light-transmitting, the outer wall is opaque; the outer wall forms at least part of the outer contour of the decorative element 100.

[0079] Specifically, the first part 110 includes a first body 111 and a first outer sidewall 112. The first outer sidewall 112 is fixed to the outer periphery of the first body 111. The first body 111 also includes a first inner sidewall 113 away from the first outer sidewall 112. The first outer sidewall 112 is opaque, while the first body 111 is translucent. The second part 120 includes a second body 121 and a second outer sidewall 122. The second outer sidewall 122 is fixed to the outer periphery of the second body 121. The second body 121 also includes a second inner sidewall 123 away from the second outer sidewall 122. The second body 121, the second outer sidewall 122, and the second inner sidewall 123 are all opaque. The third part 130 includes a third body 131 and a third outer sidewall 132. The third outer sidewall 132 is fixed to the outer periphery of the third body 131. The third outer sidewall 132 is opaque, while the third body 131 is translucent. Alternatively, both the third outer sidewall 132 and the third body 131 are translucent.

[0080] The first inner wall 113 of the first body 111 and the second inner wall 123 of the second body 121 are fixedly connected. The two ends of the first outer wall 112 are respectively fixedly connected to the two ends of the second outer wall 122. The first outer wall 112 and the second outer wall 122 are each part of the outer contour of the decorative element 100. The first body 111 and the second body 121 are spliced ​​into a plate-like piece, and the two surfaces of the first body 111 and the second body 121 are flush along the thickness direction of the decorative element 100. The first outer wall 112 and the second outer wall 122 are spliced ​​into a complete ring to form the outer contour of the decorative element 100.

[0081] Meanwhile, since the edges of both the first part 110 and the third part 130 are opaque, light emitted / entering the third part 130 will not cross over to the first part 110, or vice versa. Furthermore, the decorative component 100 as a whole is opaque at its edges, preventing the first part 110 from being exposed to external light or affecting nearby light sensors / modules, thus ensuring the overall (light sensing, lighting) functionality and display effect of the device. In other words, the decorative component 100 also has a light-blocking function.

[0082] The back of the electronic device 1 is designed with multiple light sensors and lamps that emit and receive light sources. The above design has a good isolation effect, which can prevent the light sensor from being affected by the flash, thus affecting the light sensor's judgment of ambient light and thus affecting the display effect of the main display module 20 or the rear display module 50.

[0083] In this embodiment, the decorative element 100 can be circular, that is, the first body 111 and the second body 121 are spliced ​​together to form a circular plate, and the first outer side wall 112 and the second outer side wall 122 are spliced ​​together to form a ring. In other embodiments, the decorative element 100 can also be square, elliptical, or other regular shapes, or it can be irregular. Those skilled in the art can design it according to actual needs.

[0084] In this embodiment, the second part 120 may be provided with a mounting through hole 124, which extends through the second part 120 along the thickness direction of the decorative part 100, and the third part 130 is fixed within the mounting through hole 124. Specifically, the third part 130 may be bonded to the mounting through hole 124. The shapes of the mounting through hole 124 and the third part 130 may be the same; for example, both the mounting through hole 124 and the third part 130 may be circular. In other embodiments, the mounting through hole 124 and the third part 130 may be regular shapes such as square, elliptical, or triangular, or they may be irregular shapes.

[0085] The first outer side wall 112 is opaque, preventing the third beam from entering the location of the first optical device 200 from the first outer side wall 112, thereby avoiding interference from the first optical device 200. The third outer side wall 132 is opaque, preventing the third beam from reaching the location of the second optical device 300 from the third outer side wall 132, thereby avoiding interference from the second optical device 300. In this embodiment, the rear display module is close to the aforementioned decorative element 100, therefore the third beam may be a beam emitted by the rear display module.

[0086] In this embodiment, the light-transmitting areas of the first portion 110 and / or the third portion 130 are provided with effect layers, which are used to change the light transmission effect of the first portion 110 and / or the third portion 130. That is, the effect layer can be provided only in the light-transmitting area of ​​the first portion 110, or only in the light-transmitting area of ​​the third portion 130, or both the light-transmitting areas of the first portion 110 and the light-transmitting areas of the third portion 130 are provided with effect layers.

[0087] Taking the example of an effect layer being provided in the light-transmitting area of ​​the first part 110, the effect layer can be a colored light-transmitting component, such as light yellow or light pink, for example, the light-transmitting area of ​​the first part 110. This color can be the color of the first part 110 itself, or it can be a color layer attached to the first part 110. Alternatively, the effect layer can be a diffuse reflective surface on one surface of the light-transmitting area of ​​the first part 110. The effect layer can also be achieved by setting the light transmittance of the light-transmitting area of ​​the first part 110. By providing an effect layer in the light-transmitting area of ​​the first part 110, light can pass through the first part 110, but the first optical device 200 underneath is not visible. The method of having an effect layer in the light-transmitting area of ​​the third part 130 is the same as that of having an effect layer in the light-transmitting area of ​​the first part 110, and will not be described again.

[0088] In this embodiment of the application, reference is made to Figure 11 and Figure 12 The first part 110 has a stepped portion 114, and the stepped portion 114 and the second part 120 are stacked and fixed together. It can be understood that the stepped portion 114 can protrude from the first inner sidewall 113 of the first part 110, and the height of the stepped portion 114 is less than the height of the first body 111. The overlapping portion of the second part 120 and the stepped portion 114 can be recessed downwards, thereby making the side surfaces of the first part 110 and the second part 120 flush, thus increasing the structural compactness of the decorative element 100.

[0089] By providing the step portion 114, the first part 110 and the second part 120 are reliably connected, thereby improving the structural strength of the decorative part 100.

[0090] Furthermore, the stepped portion 114 is provided with positioning holes 115, which penetrate the stepped portion 114 along the thickness direction of the decorative element 100. Positioning posts 125 are provided at the overlapping portion of the second part 120 and the stepped portion 114, and the positioning posts 125 are fixed within the positioning holes 115. It can be understood that the number of positioning holes 115 and positioning posts 125 is the same, and their positions correspond. Specifically, there can be multiple positioning holes 115 and positioning posts 125; "multiple" here refers to two or more. Multiple positioning holes 115 are arranged at intervals along the circumference of the decorative element 100. Further, multiple positioning holes 115 are arranged at equal intervals along the circumference of the decorative element 100 to increase the stability of the connection between the first part 110 and the second part 120.

[0091] It is understandable that the positioning post 125 can also be set on the step portion 114, and the positioning hole 115 can be set on the part where the second part 120 overlaps with the step portion 114. This application does not limit this.

[0092] In some other embodiments, the second part 120 is provided with a stepped portion 114, which is stacked and fixed to the first part 110. This also ensures a reliable connection between the first part 110 and the second part 120, and improves the structural strength of the decorative component 100. Furthermore, the stepped portion 114 may be provided with a positioning hole 115, and a positioning post 125 may be provided at the overlapping portion of the first part 110 and the stepped portion 114. Alternatively, the stepped portion 114 may be provided with a positioning post 125, and the overlapping portion of the first part 110 and the stepped portion 114 may be provided with a positioning hole 115. The positioning post 125 and the positioning hole 115 cooperate to improve the stability of the connection between the first part 110 and the second part 120.

[0093] In some embodiments, the first part 110 and the second part 120 are integrally molded. Specifically, the first part 110 and the second part 120 can be injection molded into one piece. During manufacturing, the first part 110 of the decorative part 100 is first injection molded using a semi-transparent material, and the molded first part 110 serves as an in-mold part. Then, the second part 120 is injection molded using an opaque material, and the first part 110 and the second part 120 together form the decorative part 100. When the second part 120 is injection molded, the injection liquid flows into the positioning hole 115. After the injection liquid in the positioning hole 115 dries, it forms a positioning post 125. The positioning post 125 is embedded in the positioning hole 115, thereby increasing the connection strength between the first part 110 and the second part 120.

[0094] After the first part 110 and the second part 120 are injection molded into decorative parts 100, the first outer wall 112 of the first part 110 can be roughened, or a light-shielding layer can be attached to the first outer wall 112 to make the first outer wall 112 opaque.

[0095] In other embodiments, reference is made to Figure 13 The decorative element 100 also includes a light guide post 500, the orthographic projection of the light guide post 500 on the decorative element 100 being at least located in the first part 110, the orthographic projection of the first optical device 200 on the decorative element 100 being located in the second part 120, and one end of the light guide post 500 being connected to the first optical device 200.

[0096] The light guide post 500 can be made of materials such as polycarbonate, glass, or epoxy resin. The light guide post 500 can efficiently transmit light within itself. By setting the light guide post 500, the light beam that the first optical device 200 needs to receive or emit is guided from the first part 110 to below the second part 120. The first optical device 200 can be positioned below the second part 120 so that it is blocked by the opaque second part 120. This design allows for a higher light transmittance in the first part 110.

[0097] In some embodiments, the light transmittance of the light-transmitting portion of the first part 110 is between 4% and 10%. That is, the first body is semi-transparent, and the light transmittance of the first body can be 4%, 5%, 6%, 7%, 8%, or 10%. The first body is set to be semi-transparent so that the first light beam can pass through while blocking the first optical device 200, thereby increasing aesthetics.

[0098] In the embodiments of this application, reference is made to Figure 14 The back cover assembly 60 or decorative element 100 also includes a protective layer comprising a first protective layer 63 and a second protective layer 64, wherein the first protective layer 63 and the second protective layer 64 are identical in shape and size to two light-transmitting areas on the back cover 61. The first protective layer 63 and the second protective layer 64 are attached to the first surface 611 of the back cover 61.

[0099] In this embodiment, the first protective layer 63 can increase the Mohs hardness of the light-transmitting area, preventing scratches on the surface of the light-transmitting area. Therefore, by providing a protective layer at the position of the back cover 61 corresponding to the light-transmitting area, the Mohs hardness of the surface where the light-transmitting area is located can be increased, enhancing scratch and abrasion resistance. This improves the image display clarity of the optical device corresponding to the light-transmitting area, thereby enhancing the display effect of the optical device. For example, the Mohs hardness of the light-transmitting area with the first protective layer 63 attached can be 7H (Hard).

[0100] In this embodiment, the second protective layer 64 can increase the Mohs hardness of the corresponding light-transmitting area, preventing scratches on the surface of the light-transmitting area. Therefore, by providing the second protective layer 64 at the position corresponding to the light-transmitting area on the back cover 61, the Mohs hardness of the surface where the light-transmitting area is located can be increased, enhancing scratch and abrasion resistance. This improves the light transmittance of the light-incident optical module corresponding to the light-transmitting area, which can be the aforementioned camera module 40 or the first optical device 200, thereby improving the performance of the optical device. For example, the Mohs hardness of the light-transmitting area with the second protective layer 64 attached can be 7H.

[0101] The back cover assembly 60 or decorative element 100 also includes an electrochromic layer 66, which is disposed on the surface of the color layer 65 facing away from the back cover 61. The electrochromic layer 66 is used to adjust the color and / or transparency of the light emitted by the light-emitting optical module, which can be the aforementioned second optical device 300 or the rear display module 50, thereby improving the visual appearance and aesthetics of the electronic device 1. It is understood that the electrochromic layer 66 can be bonded and fixed to the surface of the color layer 65 facing away from the back cover 61 using any of the following methods: optical adhesive layer, adhesive layer, or double-sided adhesive layer. The electrochromic layer 66 may have a reserved second light-transmitting area, meaning the electrochromic layer 66 does not cover the second light-transmitting area. For example, through holes of corresponding shape and size can be opened in the electrochromic layer 66 corresponding to the second light-transmitting area, allowing the second light-transmitting area to be exposed.

[0102] In this embodiment, the back cover assembly 60 or decorative element 100 may further include an anti-glare layer 67. The anti-glare layer 67 is disposed on the surface of the electrochromic layer 66 opposite to the color layer 65. The anti-glare layer 67 is used to improve the viewing angle of the back cover 61 and the light-emitting optical module, reduce the interference of ambient light on the light-receiving optical module, and reduce the reflection of the back cover 61. It is understood that the anti-glare layer 67 can be bonded and fixed to the surface of the electrochromic layer 66 opposite to the color layer 65 by any one of optical adhesive layer, adhesive layer, or double-sided adhesive layer.

[0103] In other embodiments of this application, in order to reduce the overall thickness of the back cover assembly 60 or the decorative element 100, the electrochromic layer 66 can be omitted, that is, the anti-glare layer 67 is disposed on the surface of the color layer 65 facing away from the back cover 61. Moreover, the anti-glare layer 67 can be bonded and fixed to the surface of the color layer 65 facing away from the back cover 61 by any one of optical adhesive layer, adhesive layer, or double-sided adhesive layer.

[0104] The back cover assembly 60 or decorative element 100 also includes an anti-fingerprint (AF) layer 68, which is disposed on the first surface 611 of the back cover 61 (i.e., the outer surface of the back cover 61) and covers the first protective layer 63 and the second protective layer 64. The anti-fingerprint layer 68 is used to protect the back cover assembly 60 or decorative element 100 from external environmental corrosion and can also improve the appearance and visual effect of the back cover assembly 60 or decorative element 100. The principle of the anti-fingerprint layer is to disperse the fingerprint texture, making the fingerprints on the back cover assembly 60 or decorative element 100 invisible, thus playing a certain antibacterial role. After the anti-fingerprint coating treatment, the surface of the object will exhibit good hydrophobicity and oleophobicity. Therefore, the anti-fingerprint film can also reduce the adhesion of various stains, is waterproof and oil-proof, and the stains that have been attached can be easily removed. Because it is a highly adhesive film layer, it can continue to function after wiping with a thin cloth or the like. At the same time, the film layer will not peel off, so the appearance will not deteriorate. It is understandable that the anti-fingerprint layer 68 can be bonded and fixed to the first surface 611 of the back cover 61 by any one of the optical adhesive layer, adhesive layer, or double-sided adhesive layer.

[0105] In an exemplary embodiment, the thickness of the anti-fingerprint layer 68 is 80nm-120nm, for example, 80nm, 82nm, 85nm, 88nm, 90nm, 95nm, 98nm, 100nm, 105nm, 108nm, 110nm, 115nm, 118nm, 120nm, or other values. This application does not impose specific limitations on this.

[0106] In this embodiment, the back cover assembly 60 or decorative element 100 further includes a light-reducing layer 69, which is attached to the second surface 612 of the back cover 61 (i.e., the inner surface of the back cover 61) and corresponds to the position of the optical device. The light-reducing layer 69 is used to reduce or eliminate reflected light from the light-emitting surface of the optical device and increase the transmittance and amount of light transmitted, thereby reducing or eliminating stray light. In an exemplary embodiment, the light-reducing layer 69 may be an anti-reflective (AR) film, which increases the transmittance and amount of light transmitted by reducing surface reflection of light. Therefore, by performing anti-reflective treatment on the second surface 612 of the back cover 61 corresponding to the position of the optical device, the transmittance of the optical device can be improved and the reflectance of light can be reduced to achieve the purpose of enhancing light transmission.

[0107] In this embodiment, the light-reducing layer 69 can be directly formed on the second surface 612 of the back cover 61 using a vacuum evaporation coating method, corresponding to the position of the optical device. Specifically, an anti-reflection coating is formed by performing an anti-reflection coating process on the inner surface (i.e., the second surface 612) of the back cover 61 corresponding to the position of the optical device.

[0108] In an exemplary embodiment, the thickness of the light-reducing layer 69 can be 650nm-750nm, for example, 650nm, 670nm, 680nm, 700nm, 710nm, 730nm, 740nm, 750nm, or other values. This application does not impose specific limitations on this.

[0109] In summary, the back cover assembly 60 or decorative element 100 disclosed in this application embodiment is applied to the back of an electronic device body having a mid-frame 11. The back cover assembly 60 includes a back cover 61, and the back cover 61 or decorative element 100 is at least partially a light-transmitting area. The light-transmitting area overlaps at least with the orthographic projection of the optical module of the electronic device 1 in the direction of the mid-frame 11. The optical module includes the aforementioned first optical device 200 and / or second optical device 300. The light-transmitting area is used for light emitted by the optical devices to pass through, and / or for light to pass through the back cover 61 and be received by the optical devices. The light-transmitting area includes a first surface 611 disposed opposite to the electronic device body and a second surface 612 disposed close to the electronic device body. The first surface 611 is provided with a protective layer, which corresponds at least to the optical module, and the Mohs hardness of the protective layer is greater than that of the back cover 61. Therefore, the back cover 61 or decorative element 100 of the back cover assembly 60 of this application adopts at least a partially transparent design, and by providing a protective layer on the first surface 611 (i.e. outer surface) of the light-transmitting area corresponding to the optical module, and the Mohs hardness of the protective layer is greater than that of the housing body, the scratch and abrasion resistance of the back cover 61 is improved, thus solving the problem of the lack of aesthetic appeal and integrity of the back cover of the housing assembly in the related art.

[0110] Furthermore, by providing a corresponding protective layer on the outer surface of the back cover 61 (i.e., the first surface 611) or the decorative part 100 corresponding to the position of the optical module, the back cover assembly 60 not only increases the protection of the optical module and improves the overall integrity and aesthetics of the electronic device 1, but also, by thickening the outer side of the back cover 61 or providing a certain curvature on the outer surface of the back cover 61, the back cover 61 itself can have a general Deco function. Therefore, the back cover assembly 60 or the decorative part 100 does not need a decorative ring (CAMDeco) design, making the structure of the back cover 61 simpler, the appearance more minimalist, and the overall appearance more consistent, further improving the overall appearance of the electronic device 1.

[0111] Furthermore, compared to the light-emitting optical module in related technologies, which requires an additional lamp cover to reduce the brightness of the LEDs, the back cover assembly 60 in this application embodiment can achieve the effect of reducing the brightness of the LEDs by coating / frosting the inner surface (i.e., the second surface 612) of the back cover 61 and designing it as a back cover with a light-reducing effect, thereby reducing the manufacturing cost.

[0112] In the embodiments of this application, such as Figure 14As shown, the back cover assembly 60 or decorative element 100 further includes a brightness enhancement layer 72, which is attached to the second surface 612 of the back cover 61 (i.e., the inner surface of the back cover 61) and corresponds to the position of the optical device. The brightness enhancement layer 72 is used to reduce light reflection and scattering by the optical device to achieve a preset brightness, thereby improving luminous efficiency and the brightness of light entering the optical device. In an exemplary embodiment, the brightness enhancement layer 72 may be a brightness enhancement film.

[0113] In the embodiments of this application, the brightness enhancement layer 72 is mainly based on polycarbonate (PC), polyvinyl alcohol (PVA), or PET (polyester), and prism patterns or micro / nano optical structures are fabricated on its surface using precision molding technology. Alternatively, a double-layer brightness enhancement film composite process can be employed, where the base film and a functional layer with diffusion particles are bonded together using UV resin adhesive to further optimize the light efficiency.

[0114] In this embodiment, the back cover assembly 60 or decorative element 100 may further include a light-diffusing layer. The light-diffusing layer is attached to the inner surface (i.e., the second surface 612) of the back cover 61 and covers the light-transmitting area. Specifically, the light-diffusing layer covers the light-enhancing layer 72 and the light-reducing layer 69, and corresponds to the first optical device and the second optical device. The light-diffusing layer is used to optimize the light distribution of the optical devices to achieve uniform light intensity distribution throughout the entire area.

[0115] In the embodiments of this application, such as Figure 14 As shown, the back cover assembly 60 or decorative element 100 also includes a color layer 65, which is attached to the second surface 612 (i.e., the inner surface of the back cover 61) of the back cover 61 and covers the light-reducing layer 69 and the light-diffusing layer. The color layer 65 is used to adjust the color and brightness of the image displayed by the optical device. Therefore, the color layer 65 is color-adjustable. By attaching the color layer 65 to the second surface 612 (i.e., the inner surface) of the back cover 61 and making the color layer 65 correspond to the position of the optical device, the color and brightness of the image displayed by the optical device can be adjusted, allowing the optical device to display a preset image color and brightness. Moreover, by setting the color layer 65 to adjust the screen brightness and color of the optical device, the optical device does not need to have a dot matrix screen cover added to the back cover 61, making the product structure simpler and the appearance more minimalist, further improving the overall appearance, aesthetics, and display effect of the electronic device 1.

[0116] Understandably, by attaching the color layer 65 to the inner surface of the back cover 61, impacts can be effectively cushioned, preventing the screen from cracking or the glass back cover from shattering and scattering due to accidental impacts to the electronic device 1, reducing hidden damage to the glass back cover, and maintaining the unique gloss and texture of the reinforced glass back cover while improving surface hardness. The structure of the color layer 65 may sequentially include: a protective film, a hardening layer, a transparent polyester film, an adhesive layer, and a release film.

[0117] In this embodiment, the back cover assembly 60 or decorative element 100 may include at least one or more of the following: a light-reducing layer, a light-enhancing layer, a light-diffusing layer, and a color layer. The back cover assembly 60 or decorative element 100 is used to transmit light from the optical module and form a preset display effect. Specifically, the optical device may be composed of multiple light-emitting chips, and the light-reducing layer 69 is used to reduce the brightness transmitted through the housing assembly when the optical device is in working condition; and / or, the optical device may be composed of multiple cameras, and the light-enhancing layer 72 is used to reduce light reflection and scattering when the optical device is in working condition to achieve the preset brightness; and / or, the optical device may be composed of multiple light-emitting chips, and the light-diffusing layer is used to make the light transmitted through the housing assembly uniformly displayed when the optical device is in working condition; and / or, the optical device may be composed of multiple light-emitting chips, and the color layer 65 is used to adjust the color of the light transmitted through the back cover assembly 60 or decorative element 100 when the optical device is in working condition.

[0118] It is understood that in this embodiment, the back cover assembly 60 is disposed on the second surface 612 (i.e., the inner surface of the back cover 61) and corresponds to the area where the protective layer is disposed on the first surface 611. The back cover assembly 60 or the decorative element 100 is used to transmit light from the optical module and form a preset display effect and display brightness. For example, the back cover assembly 60 or the decorative element 100 can be used to reduce the brightness transmitted through the back cover assembly 60 or the decorative element 100 when the optical device is in operation; and / or, to reduce light reflection and scattering when the optical device is in operation to achieve a preset brightness; and / or, to make the light transmitted through the back cover assembly 60 or the decorative element 100 uniformly displayed when the optical device is in operation; and / or, to adjust the color of the light transmitted through the back cover assembly 60 or the decorative element 100 when the optical device is in operation.

[0119] In this embodiment, the back cover assembly 60 or decorative element 100 may further include an adhesive layer disposed between the color layer 65 and the inner surface (i.e., the second surface 612) of the back cover 61. The color layer 65 is adhered and fixed to the back cover 61 by the adhesive layer. The adhesive layer may be an optical adhesive layer, a regular adhesive layer, or a double-sided adhesive layer. The adhesive layer reliably fixes the color layer 65 to the inner surface of the back cover 61 and also provides cushioning and shock absorption in the event of an accidental drop of the electronic device 1. Furthermore, the circumferential adhesion and fixation of the back cover 61 to the adhesive layer improves the sealing performance between the back cover 61 and the color layer 65, thereby enhancing the waterproof and dustproof performance of the electronic device 1.

[0120] It is understood that the back cover assembly 60 or decorative element 100 also includes a light-reducing layer 69, a light-enhancing layer 72, a light-diffusing layer, and a color layer 65, which can be as described above. Figure 14The order shown can also be arranged in other orders according to actual needs or process design. It is also understood that the light-reducing layer 69, light-enhancing layer 72, light-diffusing layer, and color layer 65 included in the back cover assembly 60 or decorative part 100 can be reduced or reduced as needed, or other functional film layers can be added according to actual needs. This application does not make specific limitations in this regard.

[0121] In this embodiment, the back cover assembly 60 or the decorative element 100 further includes a color layer 65 corresponding to the optical device. The color layer 65 includes multiple sub-color layers of different colors, each of which corresponds to a different area of ​​the optical device.

[0122] In this embodiment, the back cover assembly 60 or decorative element 100 further includes at least one opaque first decorative layer. The first decorative layer is disposed on the second surface 612 and overlaps with the orthographic projection of at least one electronic component of the electronic device 1 in the direction of the middle frame 11, for covering the electronic component. Therefore, by providing an opaque first decorative layer on the second surface 612 of the back cover 61, and by ensuring that the orthographic projection of the first decorative layer in the direction of the middle frame 11 overlaps with the orthographic projection of the electronic component of the electronic device 1 in the direction of the middle frame 11, the first decorative layer can cover the corresponding electronic component, while allowing it to be visualized through the transparent housing body, which is beneficial for improving the appearance and overall aesthetics of the electronic device 1.

[0123] In another embodiment of this application, the back cover assembly 60 or the decorative element 100 may further include at least one second decorative layer with a surface texture, the second decorative layer being attached to the second surface 612, the surface texture corresponding to a functional component of the electronic device 1. The functional components include, but are not limited to, sensors, ribbon cables, motherboards, coils, etc., and this embodiment of the application does not limit the specific components.

[0124] For example, the back cover assembly 60 or the decorative element 100 includes two second decorative layers with surface textures. Correspondingly, two decorative areas, namely a first decorative area and a second decorative area, are formed on the second surface 612 of the back cover assembly 60 or the surface of the decorative element 100. The first decorative area is formed by one second decorative layer, and the second decorative area is formed by another second decorative layer, such that the first and second decorative areas have the same or different texture patterns. It is understood that the first and second decorative areas can be arranged adjacently, spaced apart, or combined to form different patterns. The first and second decorative areas can have the same texture pattern or different texture patterns. For example, the first and / or second decorative areas can form texture patterns, or texture patterns can be formed by methods such as glazing, thereby achieving a better appearance and improving the appearance characteristics of the electronic device 1.

[0125] In an exemplary embodiment, the positions of the first decorative area and the second decorative layer correspond to the positions of the coil in the electronic device 1. To enhance the sense of layering and aesthetics of the electronic device 1, the shape of the first decorative area can be set to match the shape of the coil. Correspondingly, the texture pattern and color on the first decorative area also match the winding method and color of the coil. It is understood that the positions of the second decorative area and another second decorative layer can also be set to correspond to the positions of the coil in the electronic device 1.

[0126] In this embodiment, by designing the surface texture and color of the second decorative layer, the transparent shell body can present a variety of visual effects. Specifically, ultraviolet texture transfer technology can be used to design the texture of the second decorative layer. This involves using liquid UV adhesive to cure under ultraviolet light to replicate fine texture structures, thereby creating effects including brushed texture, sunburst texture, sandblasted texture, 3D surface, leather texture, iridescent effect, bumpy effect, matte finish, glossy finish, and high-gloss finish. The color can be monochrome or gradient; this application does not specifically limit this.

[0127] In this embodiment of the application, the protective layer may be a sapphire lens. The first surface 611 of the back cover 61 has a recessed groove in the direction of the second surface 612. The position of the groove corresponds to the position of the optical device. The size and shape of the groove match the size and shape of the sapphire lens. The sapphire lens is embedded in the groove, and the outer surface of the sapphire lens is flush with the first surface 611, that is, the thickness of the sapphire lens is approximately equal to the depth of the groove.

[0128] The embodiments of this application have been described in detail above. Specific examples have been used in this article to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and central idea of ​​this application.
