[0049] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0050] Foldable electronic devices unfold to reveal a large screen, the main screen, and fold to reveal another screen for user use, the secondary screen. However, the secondary screen is typically installed by creating a hole in the back cover, which limits the space available for the secondary screen, resulting in a lower screen-to-body ratio and negatively impacting the user experience.

[0051] In related technologies, refer to Figure 1 In foldable phones, the rear camera cover 9 and the secondary screen 10 are assembled on the battery cover assembly 101 respectively. The secondary screen 10 and the rear camera cover 9 are designed separately, and then the battery cover assembly 101 is assembled on the mid-frame. Therefore, the screen ratio of the secondary screen 10 is very small. This structural design seriously affects the user experience after folding.

[0052] To address the aforementioned technical issues, this disclosure provides a back cover assembly and an electronic device. Mounting holes are provided on the display module, and a decorative structure covers or fills these mounting holes. In this way, the display module serves as the back cover of the electronic device, significantly increasing the display area and maximizing the screen size. This allows users to enjoy a wider visual experience. The large display module provides users with more interactive space, enhancing the interaction between users and the electronic device and facilitating flexible use in different scenarios.

[0053] An exemplary embodiment of this disclosure provides a back shell assembly, such as Figure 2 , Figure 6 and Figure 9As shown, the back cover assembly includes a display module 1 and a decorative section. The display module 1 has at least one mounting hole 13. The decorative structure includes a first decorative section 2, which covers or fills each mounting hole 13. It should be noted that the mounting holes 13 can be used to mount devices such as cameras, proximity sensors, and flashes. In all embodiments mentioned in this disclosure, the device installed in the mounting holes 13 is a camera. The decorative structure provides physical protection and stable support and fixation for the mounted cameras, proximity sensors, flashes, and other devices. By covering or filling all the mounting holes 13 with a first decorative section 2, the overall aesthetics of the phone are improved. The decorative structure covers or fills all the mounting holes 13, thereby ensuring the integrity of the appearance and effectively reducing hard-to-clean areas.

[0054] Mounting hole 13 can be provided one or more, for example, see [reference]. Figure 2 and Figure 3 The display module 1 has two mounting holes 13, which are completely covered by the first decorative part 2. The two mounting holes 13 can be used as follows: Figure 2 The arrangement shown can be along the length of the electronic device, or along the width of the electronic device, or along the diagonal of the electronic device. In another embodiment, refer to... Figure 7 and Figure 10 The display module 1 has a mounting hole 13, through which the first decorative part 2 can be inserted. Figure 7 The cover shown is applied to the mounting hole 13, or as... Figure 10 The filling shown is inside the mounting hole 13.

[0055] The back shell assembly can be applied to both non-foldable and foldable electronic devices. When the back shell assembly is applied to a foldable electronic device, the display module 1 can be a flexible screen. In this case, the display module 1 can completely cover the back shell of the electronic device. Therefore, the display module 11 can fold along with the electronic device. Alternatively, the display module 1 can be installed on only one side of the back shell of the foldable electronic device.

[0056] Using the display module 1 as the back cover of the electronic device greatly increases the display area of ​​the electronic device, maximizes the screen, and allows users to enjoy a wider visual experience. The large display module 1 provides users with more interactive space, enhances the interactive experience between users and electronic devices, and facilitates flexible use by users in different scenarios.

[0057] In one embodiment, reference is made to Figure 3 and Figure 4The first decorative part 2 includes a decorative panel 21, a decorative frame 22 disposed on the edge of the upper surface of the decorative panel 21, and a protective plate 23. The protective plate 23 is located within a protective plate mounting groove formed by the decorative panel 21 and the decorative frame 22. For example, see... Figure 2 , Figure 6 and Figure 9 The decorative panel 21 is shaped like a racetrack. Of course, in other embodiments, the decorative panel 21 can also be other shapes, such as ellipse, square, or circle. The decorative frame 22 and the protective panel 23 are adapted to the shape of the decorative panel 21. The decorative panel 21 and the decorative frame 22 can be an integral structure or a separate design.

[0058] In embodiments where mounting holes 13 are provided in multiple locations, exemplarily, refer to... Figure 2 and Figure 3 In this embodiment, there are two mounting holes 13, with a decorative frame 22 surrounding all the mounting holes 13, and a decorative panel 21 covering all the mounting holes 13. In an embodiment where there is only one mounting hole 13, refer to... Figure 7 Decorative panel 21 covers mounting hole 13, or, refer to Figure 10 The decorative panel 21 is shaped to match the mounting hole 13.

[0059] When the decorative panel 21 is positioned above the display module 1 and covers the mounting hole 13, an annular light-shielding layer can also be provided between the first decorative part 2 and the display module 1. After the first decorative part 2 and the display module 1 are assembled, there may be gaps between them. By providing a light-shielding layer between the first decorative part 2 and the display module 1, the gaps between them can be effectively sealed, preventing light leakage through these gaps and thus maintaining the camera's shooting quality. Simultaneously, due to limitations in existing screen manufacturing processes and packaging technologies, it is impossible to achieve a completely borderless screen, resulting in black borders. Therefore, by covering the display module 1 with the first decorative part 2, the light-shielding layer covers the black borders of the screen, thus creating a borderless full-screen appearance and improving the user experience.

[0060] In another embodiment, refer to Figure 10 There is one mounting hole 13, and the outer peripheral surface of the decorative frame 22 mates with the mounting hole 13. It can be understood that a mounting hole 13 is provided on the display module 1, and the first decorative part 2 is inserted into the mounting hole 13, so that the outer peripheral surface of the decorative frame 22 fits against the hole wall of the mounting hole 13.

[0061] During installation, the decorative panel 21 is adhered to the display module 1 or into the mounting hole 13 using an adhesive layer, and then the protective plate 23 is adhered to the protective plate mounting groove using glue or other means. This design provides installation space for the protective plate 23 through the decorative panel 21 and decorative frame 22. Together, the decorative panel 21, decorative frame 22, and protective plate 23 form a more robust structure, protecting the internal structure of the first decorative part 2 from external impacts and improving the overall aesthetics of the electronic device.

[0062] In one embodiment, reference is made to Figure 3 The decorative panel 21 has at least one first through hole 215, and the protective plate 23 covers each of the first through holes 215. For example, see... Figures 3 to 5 As shown, the decorative panel 21 has three first through holes 215, which correspond to the main camera 5, the secondary camera 6, and the flash 103 in the electronic device, respectively. The protective plate 23 can be made of materials with good light transmittance, such as glass, resin, acrylic, and mineral glass. Thus, by setting up the protective plate 23, the internal components of the electronic device can be protected from scratches, dust, and liquids. The use of a material with good light transmittance ensures that light passes smoothly through the through holes, without affecting the normal function of the camera and flash 103, thus guaranteeing the clarity of the captured images and videos.

[0063] In one embodiment, reference is made to Figure 7 and Figure 10 The first through-hole 215 includes a flash mounting hole 211 and at least one lens mounting hole 216. That is, multiple cameras can be installed inside the electronic device, and thus multiple lens mounting holes 216 corresponding to each camera can be provided on the decorative panel 21. This design provides independent mounting holes 13 for the flash 103 and the lens, ensuring they each have sufficient space for installation and fixation, avoiding interference and conflict between different components, ensuring their normal and stable operation, reducing the risk of damage to one component affecting other components, improving the overall aesthetics of the electronic device, and guaranteeing the accuracy of shooting and lighting effects.

[0064] In one embodiment, reference is made to Figure 6 and Figure 9At least one lens mounting hole 216 includes a first lens mounting hole 212 and a second lens mounting hole 213, and a flash mounting hole 211 is disposed between the first lens mounting hole 212 and the second lens mounting hole 213. For example, the flash mounting hole 211 is positioned directly in the middle of the first lens mounting hole 212 and the second lens mounting hole 213. This design, placing the flash 103 between the two lenses, can more effectively provide auxiliary lighting for both lenses. When taking photos or videos, the light from the flash 103 can more evenly cover the field of view of both lenses, improving the shooting effect and reducing shadow problems caused by the misalignment of the flash 103.

[0065] In another embodiment, the lens mounting hole 216 includes a first lens mounting hole 212 and a second lens mounting hole 213, and the first lens mounting hole 212, the second lens mounting hole 213, and the flash mounting hole 211 are arranged side by side in a predetermined direction. For example, refer to... Figure 2 The decorative panel 21 has, from top to bottom, a flash mounting hole 211, a second lens mounting hole 213, and a first lens mounting hole 212. The vertical axes of the flash mounting hole 211, the second lens mounting hole 213, and the first lens mounting hole 212 can be aligned on the same straight line or on different straight lines. This design positions the flash 103 above the lens, providing effective auxiliary lighting during shooting. Simultaneously, the fixed relative position of the flash 103 to the lens ensures even light distribution and reduces shadows and vignetting.

[0066] In one embodiment, reference is made to Figure 3 and Figure 7 The decorative panel 21 covers each mounting hole 13, and a blocking protrusion 24 is provided on the edge of the decorative panel 21 facing the display module 1. Exemplarily, when the first decorative part 2 covers the mounting holes 13, there is an overlapping area between the decorative panel 21 and the display module 1. This overlapping area can be filled with buffer adhesive to form a buffer section. This buffer section serves two purposes: firstly, it adheres the decorative panel 21 to the display module 1; secondly, the buffer adhesive acts as a buffer medium, preventing damage to the display module 1 from external impacts. The blocking protrusion 24 on the edge of the decorative panel 21 facing the display module 1 is filled with buffer adhesive on its radially inner side. This design prevents foreign objects from entering the buffer section and causing screen damage due to dust accumulation. Combined with the use of buffer adhesive, the blocking protrusion 24 further enhances the seal between the decorative panel 21 and the display module 1, ensuring the cleanliness and dryness of the device's interior.

[0067] In one embodiment, reference is made to Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 10 and Figure 11 The display module 1 includes a cover plate 11 and a display panel 12 disposed on the inner surface of the cover plate 11. The cover plate 11 can be entirely transparent or partially transparent, as long as the content displayed on the display panel 12 can be displayed through the cover plate 11. The display panel 12 can be a liquid crystal display (LCD), OLED (Organic Light-Emitting Diode), or the like.

[0068] like Figure 4 As shown, the cover plate 11 is provided with at least one second through hole 111, and the display panel 12 is provided with a third through hole 121 corresponding to the at least one second through hole 111. The second through holes 111 and the third through holes 121 constitute the mounting hole 13. That is, the number of first through holes 215 can be one or more, and the number of third through holes 121 is the same as the number of first through holes 215. The decorative structure also includes a second decorative part 3, which is disposed inside the first decorative part 2.

[0069] For example, refer to Figure 4 and Figure 5 There are two mounting holes 13. The second decorative part 3 includes decorative units corresponding to the two mounting holes 13 one by one. The decorative unit includes a main decorative unit 31 and a secondary decorative unit 32. The main decorative unit 31 is used to install the main camera 5, and the secondary decorative unit 32 is used to install the secondary camera 6. A flash mounting area can also be set on the secondary decorative unit 32. The main decorative unit 31 is connected to the first lens mounting hole 212, and the secondary decorative unit 32 is connected to the second lens mounting hole 213 and the flash mounting hole 211. The main decorative unit 31 and the secondary decorative unit 32 are connected by a connecting part.

[0070] In another embodiment, reference is made to Figure 7 and Figure 10 The device has one mounting hole 13, and the second decorative part 3 is adapted to the mounting hole 13. The second decorative part 3 is divided into a main camera mounting area and a secondary camera mounting area, with a flash mounting area located between the main camera mounting area and the secondary camera mounting area. This makes the processing and production of the second decorative part 3 simpler and more convenient, and improves production efficiency.

[0071] In one embodiment, reference is made to Figure 3 and Figure 4 The outer surface of the decorative unit is provided with a first boss (e.g., surrounding the corresponding second through hole 111) Figure 4The first main boss 311 in the cover plate 11 has a first area 112 exposed through each third through hole 121 on its inner surface. That is, since the diameter of the third through hole 121 is larger than the diameter of the second through hole 111, the inner surface of the cover plate 11 has a first area 112 exposed through the third through hole 121. The first boss abuts against the corresponding first area. For example, refer to Figure 4 When the cover plate 11 and the display panel 12 are assembled together, the center point of the third through hole 121 on the display panel 12 and the center point of the second through hole 111 on the cover plate 11 are on the same center line. Since the diameter of the third through hole 121 is larger than the diameter of the second through hole 111, there will be an area in the cover plate 11 that is not covered by the display panel 12 in the third through hole 121. This area is the first area 112.

[0072] For example, refer to Figure 3 and Figure 4 The display module 1 has two mounting holes 13. The second decorative part 3 includes a main decorative unit 31 and a secondary decorative unit 32 corresponding to the two mounting holes 13. The main decorative unit 31 and the secondary decorative unit 32 are connected by a connecting part. For ease of description, the second through hole 111 corresponding to the main camera 5 will be defined as the second main through hole, the second through hole 111 corresponding to the secondary camera 6 will be defined as the second secondary through hole, the first through hole 215 corresponding to the main camera 5 will be defined as the first main through hole, the first through hole 215 corresponding to the secondary camera 6 will be defined as the first secondary through hole, the third through hole 121 corresponding to the main camera 5 will be defined as the third main through hole, and the third through hole 121 corresponding to the secondary camera 6 will be defined as the third secondary through hole. A first main boss 311 is provided on the outer surface of the main decorative unit 31 around the second main through hole. The first main boss 311 abuts against the area exposed through the third main through hole on the inner surface of the cover plate 11. A first sub-protrusion is provided on the outer surface of the secondary decorative unit 32 around the second secondary through hole. The first sub-protrusion abuts against the area exposed on the inner surface of the cover plate 11 through the third secondary through hole. In this embodiment, the first main protrusion 311 and the first sub-protrusion together constitute the first protrusion.

[0073] With this design, a second decorative part 3 is provided on the inner side of the cover plate 11. The first protrusion on the second decorative part 3 abuts against the cover plate 11. The first protrusion can provide support for the cover plate 11. When the electronic device is subjected to external pressure or collision, the first protrusion can act as a buffer to buffer the impact force on the display module 1. This helps to prevent the display panel 12 from being damaged by pressure and also prevents the camera structure inside the second decorative part 3 from being damaged.

[0074] The first boss is bonded to the area exposed through the third through hole 121 on the inner surface of the cover plate 11 by an adhesive layer. The adhesive layer tightly bonds the first boss and the first area together to form a stable connection, which can effectively prevent the first boss and the first area from loosening or shifting, prevent the cover plate 11 from falling off, and thus improve the stability of the entire structure.

[0075] In one embodiment, reference is made to Figure 3 and Figure 4 A second protrusion (e.g.) is provided on the outer surface of the decorative unit. Figure 4 The second main boss 312 is located radially inside the corresponding first boss and abuts against the first decorative part 2. For example, see reference... Figure 3 , Figure 4 and Figure 5 A second boss is provided radially inside the first boss. Adhesive can be applied to the second boss to connect the second decorative part 3 to the first decorative part 2. This arrangement ensures a tight fit between the second boss and the first decorative part 2, forming an effective sealing barrier that helps prevent moisture, dust, or other impurities from entering the interior of the decorative unit, thereby protecting the internal components from damage.

[0076] In other embodiments, for ease of description, the second protrusion located corresponding to the main camera 5 will be defined as the second main protrusion 312, and the second protrusion located corresponding to the secondary camera 6 will be defined as the second secondary protrusion. (Refer to...) Figure 3 To ensure overall aesthetics, the diameters of the main decorative part and the secondary decorative part are set to the same size. Since a flash is provided on the secondary camera 6, the total area of ​​the fifth secondary through hole and the flash mounting hole 211 on the secondary decorative part corresponding to the secondary camera 6 is greater than the area of ​​the fifth main through hole on the main decorative part corresponding to the main camera 5. To better ensure the sealing connection between the first decorative part 2 and the second decorative part 3, the upper part of the second main boss 312 extends into the first main through hole. The second main boss 312 is provided with a fifth main through hole that communicates with the first main through hole. The upper part of the second secondary boss contacts the lower surface around the first secondary through hole of the decorative panel 21. The second secondary boss is provided with a fifth secondary through hole that communicates with the first secondary through hole.

[0077] The adhesive layer between the decorative panel 21 corresponding to the main camera 5 and the cover plate 11 can extend to the side wall of the second main boss 312 and the hole wall of the second main through hole, and the adhesive layer between the decorative panel 21 and the cover plate 11 corresponding to the secondary camera 6 extends to the top surface of the second secondary boss.

[0078] In one embodiment, reference is made to Figure 7 and Figure 8A mounting hole 13 is provided, and the inner surface of the cover plate 11 has a second region 113 exposed through the third through hole 121. The edge region of the outer surface of the second decorative part 3 abuts against the second region 113. For example, refer to... Figure 7 and Figure 10 A mounting hole 13 is provided on the display module 1. Therefore, a second through hole 111 is provided on the cover plate 11, and a third through hole 121 is provided on the display panel 12. The edge area of ​​the outer surface of the second decorative part 3 abuts against the area exposed through the third through hole 121 on the inner surface of the cover plate 11. With this design, the second decorative part 3 abuts against the cover plate 11, and the second decorative part 3 can provide support for the cover plate 11. When the electronic device is subjected to external pressure or collision, the edge area of ​​the second decorative part 3 can act as a buffer to cushion the impact force on the display module 1, which helps to prevent damage to the display panel 12 caused by pressure, and can also prevent damage to the camera structure inside the second decorative part 3.

[0079] In one embodiment, reference is made to Figure 7 , Figure 8 , Figure 10 and Figure 11 A third boss 33, adapted to the shape of the mounting hole 13, is provided on the radially inner side of the edge region of the second decorative part 3. The third boss 33 passes through the mounting hole 13 and abuts against the first decorative part 2. (Refer to...) Figure 7 , Figure 8 , Figure 10 and Figure 11 The side surface of the third protrusion 33 abuts against the wall of the mounting hole 13, and the upper surface of the third protrusion 33 abuts against the lower surface of the decorative panel 21.

It should be noted that, referring to Figure 8 and Figure 11An annular groove 214 is provided on the lower surface of the decorative panel 21, that is, the first through hole 215 is provided at the bottom of the annular groove 214. The outer surface of the third boss 33 is provided with an annular protrusion 332 that matches each annular groove 214, and the annular protrusion 332 abuts against the bottom of the annular groove 214. For example, refer to... Figure 7 , Figure 8 , Figure 10 and Figure 11 The first through hole 215 includes a flash mounting hole 211, a first lens mounting hole 212, and a second lens mounting hole 213. Therefore, the fourth through hole 331 includes a fourth flash through hole, a fourth main through hole, and a fourth auxiliary through hole that correspond one-to-one with the flash mounting hole 211, the first lens mounting hole 212, and the second lens mounting hole 213. An annular groove 214 is provided around each of the first through holes 215 on the lower surface of the decorative plate 21. An annular protrusion 332 that matches the annular groove 214 is provided around each of the fourth through holes 331. During assembly, the bottom of the annular groove 214 abuts against the upper surface of the annular protrusion 332. This design, with the matching of the annular protrusion 332 and the annular groove 214, ensures that the second decorative part 3 can be accurately aligned and connected to the first decorative part 2 during installation, reducing installation problems caused by positional deviations and improving the stability and reliability of the overall structure. The tight contact between the annular protrusion 332 and the annular groove 214 forms a solid mechanical connection, reducing misalignment caused by vibration or external force. At the same time, it can also prevent moisture, dust or other impurities from seeping into the device through the through hole, protecting internal components such as the flash 103 and lens from damage.

[0081] In one embodiment, reference is made to Figure 9 , Figure 10 and Figure 11 The outer periphery of the decorative frame 22 of the first decorative part 2 mates with the mounting hole 13, and the edge region of the outer surface of the third boss 33 abuts against the edge region of the inner surface of the decorative panel 21. For example, when the first decorative part 2 is inserted into the mounting hole 13, a support platform is provided at the edge of the lower surface of the decorative panel 21, and the support platform abuts against the edge region of the outer surface of the third boss 33. This design provides a stable support for the first decorative part 2 through the abutment between the edge region of the outer surface of the third boss 33 and the edge region of the inner surface of the decorative panel 21, helping to reduce loosening or displacement caused by vibration or external forces, thereby enhancing the stability of the entire decorative structure.
