Description

Technical Field

[0001] This application relates to the field of electronic devices and accessories, and in particular to an electronic device, a protective case, and an electronic device component. Background Technology

[0002] As the computing power of tablet computers continues to improve, the combination of tablet computers with protective cases that include keyboards to achieve a tablet-laptop hybrid model is becoming an important office practice.

[0003] When a tablet needs to charge a keyboard case, a typical charging solution involves a charging port on the tablet's casing with a spring-loaded connector that connects to the tablet's power source. A corresponding spring-loaded interface on the keyboard case connects to a rechargeable battery within the case. The tablet then charges the keyboard case by connecting the spring-loaded connector to the spring-loaded interface.

[0004] However, this charging solution requires a charging hole that runs through the tablet's casing, which disrupts the overall continuity of the casing and affects the tablet's aesthetics. Summary of the Invention

[0005] This application provides an electronic device, a protective case, and an electronic device component, which can ensure the overall continuity of the electronic device's casing and also achieve an all-metal appearance for the electronic device's casing, thereby improving the aesthetic appeal of the electronic device.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0007] In a first aspect, embodiments of this application provide an electronic device, which includes a housing and a first inductor coil assembly. The first inductor coil assembly includes a first inductor coil, and the orthographic projection of the first inductor coil in a reference plane falls into the orthographic projection of a first light-transmitting hole in the reference plane, wherein the reference plane is perpendicular to the axial direction of the first light-transmitting hole.

[0008] The electronic device provided in this application embodiment, by aligning a first inductor coil with a first light-transmitting hole on the device's casing, and coupling the first inductor coil with an external second inductor coil, enables the electronic device to charge the rechargeable battery of another device. Alternatively, it enables other devices to charge the electronic device. Furthermore, it eliminates the need for additional charging holes on the device's casing, ensuring the continuity of the cover and improving the device's aesthetics. Simultaneously, since the first inductor coil is positioned corresponding to the first light-transmitting hole, there is no casing obstructing the connection between the first and second inductor coils, allowing the electronic device's casing to be made of metal. The metal casing does not affect the coupling between the first and second inductor coils, solving the problem that wireless charging can only be used with plastic casings, achieving a fully metal casing, and thus improving the aesthetics of the electronic device.

[0009] In one possible implementation, the electronic device further includes a decorative component assembly, which includes a decorative body connected to the housing. The decorative body includes a panel portion disposed opposite to the first light-transmitting hole, and a first inductor coil assembly is disposed on the panel portion.

[0010] Integrating the first inductor coil assembly onto the decorative component assembly can reduce mutual interference between the first inductor coil and the internal electronic components of the electronic device, and can improve the efficiency of the electronic device in charging the rechargeable battery in the protective case.

[0011] In one possible implementation, the first inductor coil assembly further includes a magnetic shielding base, wherein the first inductor coil is disposed on the magnetic shielding base, and the magnetic shielding base is located on the side of the first inductor coil facing away from the outside of the housing.

[0012] The magnetic shielding base has a magnetoresistance effect, which can isolate the magnetic field. The magnetic shielding base can prevent the first inductor coil from interfering with the electronic components inside the electronic device, thereby improving the charging efficiency of the electronic device to charge the rechargeable battery in the protective case.

[0013] In one possible implementation, the magnetic isolation base has a first receiving groove, and the first inductor coil is disposed in the first receiving groove.

[0014] The opening of the first receiving slot on the magnetic shielding base faces outwards from the electronic device. This first receiving slot can converge the magnetic signal generated by the first inductor coil, increasing the induced current of the second inductor coil positioned opposite the first inductor coil. This improves the charging efficiency of the electronic device for the rechargeable battery inside the protective case. Furthermore, it reduces interference from the first inductor coil to the internal electronic components, ensuring the normal operation of the electronic device.

[0015] In one possible implementation, the first inductor coil assembly is disposed on the side of the panel facing the outside of the housing.

[0016] In this way, since the first inductor coil assembly is located on the side of the panel facing the outside of the electronic device, the panel can be made of metal, and there will be no shielding effect on the first inductor coil assembly and the second inductor coil, which can also improve the aesthetics of the electronic device.

[0017] In one possible implementation, a second receiving groove is provided on the side of the panel facing the outside of the housing, and the first inductor coil assembly is disposed in the second receiving groove.

[0018] In this approach, the panel can be made of metal without affecting the shielding of the first and second inductors, and it also enhances the aesthetics of the electronic device. Furthermore, since there is no height restriction on the surface of the panel facing the outside of the electronic device due to the first inductor, the light-transmitting sheet can be fixedly connected to the outer periphery of the panel using adhesive (e.g., with adhesive backing), which improves the assembly stability of the light-transmitting sheet and also enhances the sealing of the electronic device.

[0019] In one possible implementation, the first inductor coil assembly is disposed on the outer side of the panel facing away from the housing. This facilitates the fixing of the first inductor coil assembly to the panel.

[0020] In one possible implementation, the first inductor coil is bonded to the outer side of the panel facing away from the housing using adhesive. This facilitates the fixing of the first inductor coil assembly to the panel.

[0021] In one possible implementation, the electronic device further includes: a functional device disposed inside the electronic device, a through hole being provided on the panel, the light-incident surface of the functional device being disposed opposite to the through hole, and a first inductor coil being disposed around the through hole.

[0022] This allows the first inductor coil to avoid obstacles such as flash, camera module, and / or electroacoustic devices. Furthermore, it allows the first inductor coil's coil area to be maximized within the size constraint of the first light-transmitting hole, thereby improving the charging efficiency of the electronic device for the rechargeable battery inside the protective case.

[0023] In one possible implementation, the first light-transmitting hole is circular, and the first inductor coil is annular.

[0024] The first inductor coil of the ring has an equal ring width, which makes the magnetic field generated by the first inductor coil have a regular magnetic field line distribution, which is beneficial to improving the charging efficiency of electronic devices for charging rechargeable batteries in protective cases.

[0025] In one possible implementation, the first light-transmitting hole is circular, and the first inductor coil is elliptical.

[0026] Electronic components can be mounted on the panel portions on both sides of the elliptical ring-shaped first inductor coil along its minor axis, optimizing the structural arrangement of the decorative component assembly. Furthermore, the coil area of ​​the first inductor coil can be designed to be as large as possible within the size constraint of the first light-transmitting hole, thereby improving the charging efficiency of the electronic device for the rechargeable battery within the protective case.

[0027] In one possible implementation, the first inductor coil is elliptical and includes: a first semicircular portion, a second semicircular portion, a first straight portion, and a second straight portion. The two ends of the first semicircular portion are a first end and a second end, respectively. The two ends of the second semicircular portion are a third end and a fourth end, respectively. The first and third ends are positioned opposite each other. The two ends of the first straight portion are connected to the first and third ends, respectively. The second and fourth ends are positioned opposite each other, and the two ends of the second straight portion are connected to the second and fourth ends, respectively. This can be understood as the first inductor coil being racetrack-shaped. Compared to a standard elliptical ring-shaped first inductor coil, the racetrack-shaped first inductor coil reduces the manufacturing difficulty of the first inductor coil shape. Furthermore, the racetrack-shaped first inductor coil has a larger central area, allowing for the placement of more electronic components within the corresponding area of ​​the electronic device.

[0028] In one possible implementation, the electronic device further includes a fastener. The first inductor coil is elliptical in shape, and the panel portion has mounting holes on both sides along the minor axis of the first inductor coil. The fastener passes through the mounting holes and is used to fix the panel portion inside the electronic device.

[0029] The closer the fastening point of the fastener on the panel is to the edge of the panel, the better the assembly stability of the panel. The elliptical ring-shaped first inductor coil can provide a clearance position for the fastener, thereby improving the assembly stability of the decorative component on the electronic device.

[0030] In one possible implementation, the electronic device further includes: an annular magnetic shield, the functional device including a camera module, the annular magnetic shield being coaxially disposed with the through hole, the annular magnetic shield forming an accommodating space, and at least a portion of the camera module being disposed in the accommodating space.

[0031] This reduces the interference of the first inductor coil on the camera module, and minimizes its impact on the camera module's performance during operation. For example, it reduces the likelihood of the first inductor coil interfering with the camera module and causing patterns or other defects in the image.

[0032] In one possible implementation, the first inductor coil has a first end face and a second end face disposed opposite to each other along its axial direction. The annular magnetic shielding sheet has a third end face and a fourth end face disposed opposite to each other along its axial direction. In a first direction, the first end face and the second end face are located between the third end face and the fourth end face, wherein the first direction is parallel to the axial direction of the through hole.

[0033] This can further reduce the interference of the first inductor coil to the camera module and reduce the impact of the first inductor coil on the camera module's performance when it is working.

[0034] In one possible implementation, the functional device includes a camera module, wherein the absolute value of the difference between the operating frequency of the first inductor coil and the acquisition frequency of the camera module is greater than or equal to 350 kHz.

[0035] In this way, the difference between the operating frequency of the first inductor coil and the operating frequency of the camera module can be increased, thereby reducing the impact of the first inductor coil on the shooting of the camera module.

[0036] In one possible implementation, the decorative element body further includes a mounting portion surrounding the panel portion and connected to the panel portion, and the mounting portion being connected to the inner surface of the housing.

[0037] This reduces the assembly difficulty of the decorative part body and minimizes the impact of dimensional errors between the decorative part body and the first light-transmitting hole. In one possible implementation, the electronic device further includes a light-transmitting sheet, which is sealed to the first light-transmitting hole.

[0038] Transparent films can decorate the appearance of electronic devices and also protect their internal components.

[0039] In one possible implementation, the light-transmitting sheet has a light-transmitting area and a non-light-transmitting area, and at least a portion of the orthographic projection of the first inductor coil in the reference plane falls into the orthographic projection of the non-light-transmitting area in the reference plane.

[0040] The non-transparent area can shield the first inductor coil, improving the aesthetics of the electronic device.

[0041] In one possible implementation, the housing is a metal housing. This improves the aesthetic appeal of the electronic device.

[0042] Secondly, this application provides a protective cover, including: a shell and a second inductor coil. The shell has a second light-transmitting hole, which is used to be assembled with the first light-transmitting hole of the electronic device as described above. The second inductor coil is disposed in the shell and surrounds the second light-transmitting hole.

[0043] The protective case provided in this application embodiment can be coupled to the first inductor coil in the electronic device shown above through the second inductor coil, so that the electronic device can charge the rechargeable battery in the protective case.

[0044] In one possible implementation, the second light-transmitting hole is used for concentric assembly with the first light-transmitting hole, and the area of ​​the second light-transmitting hole is smaller than the area of ​​the first light-transmitting hole.

[0045] In this way, a portion of the protective case overlaps with the first light-transmitting hole. By placing the second inductor coil within this overlapping area and arranging it around the second light-transmitting hole, the second inductor coil can be positioned directly opposite the first inductor coil, thereby improving the charging efficiency of the electronic device for the rechargeable battery in the protective case.

[0046] In one possible implementation, the protective cover further includes: an electrical device disposed within the housing and a rechargeable battery, the electrical device being electrically connected to the rechargeable battery, and the rechargeable battery being electrically connected to the electrical device. The rechargeable battery stores electrical energy to power the electrical device.

[0047] Thirdly, embodiments of this application provide an electronic device component, including: an electronic device and a protective case, wherein the electronic device is the electronic device described above, and the protective case is the protective case described above.

[0048] The electronic device component provided in this application embodiment, since it includes the electronic device as described above and the protective case as shown above, can achieve the same technical effects and solve the same technical problems as the electronic device and protective case described above.

[0080] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0081] The electronic devices provided in this application embodiment can be mobile phones, tablet computers, desktop computers, laptop computers, handheld computers, laptops, ultra-mobile personal computers (UMPCs), netbooks, cellular phones, personal digital assistants (PDAs), augmented reality (AR) devices, virtual reality (VR) devices, artificial intelligence (AI) devices, wearable devices, in-vehicle devices, smart home devices, and / or smart city devices. This application embodiment does not impose any special limitations on the specific type of electronic device. For ease of understanding, this application embodiment uses a tablet computer as an example for illustration.

[0082] Figure 1 A schematic diagram of the structure of an electronic device component 100 in an embodiment of this application when it is in the open state. Figure 1 , Figure 2 for Figure 1 An exploded view of the electronic device component 100 shown, with reference to Figure 1 and Figure 2 As shown, the electronic device component 100 provided in this application embodiment includes an electronic device 200 and a protective case 300.

[0083] Electronic device 200 has a front side 200a and a back side 200b. The front side 200a of electronic device 200 has a display interface, through which electronic device 200 presents images or videos to a user. The back side 200b of electronic device 200 is opposite to the front side 200a.

[0084] The protective case 300 includes a housing and an electrical device disposed within the housing. The electrical device can be a lighting device such as a lamp or flashlight, an electroacoustic device such as a speaker or microphone, or an external input device such as a keyboard. In this application, the electrical device includes, but is not limited to, the examples above. This application does not specifically limit the type of electrical device; for ease of understanding, a keyboard is used as an example in this application.

[0085] The housing includes a keyboard section 310, a support section 320, and a hinge mechanism 330.

[0086] A hinge mechanism 330 connects the support portion 320 and the keyboard portion 310. The support portion 320 is rotatably connected to the keyboard portion 310 via the hinge mechanism 330, allowing the electronic device component 100 to switch between a closed and an open state. In some embodiments of this application, the hinge mechanism 330 may include a hinge 331 and a bushing 332. The hinge 331 is fixed to the keyboard portion 310, and the bushing 332 is fixed to the support portion 320. The hinge 331 passes through the bushing 332 and is rotatable within the bushing 332. In some embodiments of this application, the fixed positions of the hinge 331 and the bushing 332 can be interchanged; that is, the hinge 331 is fixed to the support portion 320, and the bushing 332 is fixed to the keyboard portion 310. Of course, in other embodiments of this application, the protective sleeve 300 may not include the hinge mechanism 330, and the support portion 320 and the keyboard portion 310 may be connected using a deformable material. For example, a fabric can be used to connect the support part 320 and the keyboard part 310, and the deformation of the fabric can allow the electronic device component 100 to switch between a closed state and an open state.

[0087] The keyboard section 310 is generally rectangular and flat. A keyboard 311 is provided on the keyboard section 310. The keyboard section 310 can establish a signal transmission relationship with the electronic device 200 via a wired or wireless connection. For example, the keyboard section 310 can connect to the electronic device 200 via Bluetooth, and the user can type information into the electronic device 200 by typing on the keyboard 311.

[0088] The support portion 320 is also generally rectangular flat. In some embodiments of this application, the support portion 320 includes a support plate and a leather sleeve covering the support plate to improve the tactile feel during use. The support portion 320 has a fixing surface 320a, which is used to fix the back surface 200b of the electronic device 200. It is understood that in some embodiments of this application, the keyboard portion 310 and the support portion 320 may also be triangular flat, polygonal flat, etc., and this application does not specifically limit the shape of the keyboard portion 310 and the support portion 320.

[0089] The support portion 320 secures the electronic device 200 in a detachable manner. For example, the support portion 320 may contain a first magnet assembly, and the electronic device 200 may contain a second magnet assembly. The magnetic attraction between the first and second magnet assemblies secures the back surface 200b of the electronic device 200 to the fixing surface 320a of the support portion 320. As another example, the fixing surface 320a has a slot at its edge corner, allowing the corner of the electronic device 200 to engage with the slot, thus securing the electronic device 200 to the fixing surface 320a. In this way, the electronic device 200 can be detached from the protective cover 300 and switched to an independent operating mode for separate use.

[0090] Of course, in some other embodiments of this application, the support portion 320 may fix the electronic device 200 in a non-removable manner.

[0091] Figure 3 A schematic diagram of the structure of a protective sleeve 300 is provided for one embodiment of this application, with reference to... Figure 3 and combined Figure 2 As shown, in some embodiments of this application, the support portion 320 may include: a first portion 321 and a second portion 322, the boundary line between the first portion 321 and the second portion 322 being parallel to or substantially parallel to the rotation axis of the rotating shaft mechanism 330, and the second portion 322 being able to rotate about the first portion 321 with the boundary line between the first portion 321 and the second portion 322 as the rotation axis. Please refer to... Figure 1 When the electronic device 200 needs to be upright, the second part 322 can be flipped so that the second part 322, the first part 321, and the desktop form a triangular support structure, thereby enabling the electronic device 200 to be tilted upright, thus facilitating the user's use of the electronic device 200. Alternatively, please combine with... Figure 4 When the electronic device 200 needs to be erected, the first part 321 can be flipped so that the first part 321, part of the electronic device 200 and part of the keyboard part 310 form a triangular support structure, thereby achieving the diagonal support to erect the electronic device 200.

[0092] Please continue to refer to this. Figure 3 and combined Figure 2As shown, in some embodiments of this application, the protective case 300 may further include a storage section 340, which is cylindrical in shape. When the electronic device 200 includes a stylus 210, the storage section 340 can house the stylus 210 to facilitate the overall carrying of the electronic device 200. The stylus 210 is a pen-shaped tool used to input commands to the electronic device 200 with a touchscreen. Users can use the stylus 210 to tap the touchscreen to select files or draw. Exemplarily, the storage section 340 may be located at the junction of the support section 320 and the keyboard section 310, and is integrally formed with the hinge 331, reusing the hinge 331 as the storage section 340, thereby optimizing the structural design of the protective case 300. This application does not impose specific limitations on the location of the storage section 340. Of course, it is understood that in other embodiments of this application, the electronic device 200 may also have a storage hole, in which the stylus 210 is housed.

[0093] Figure 5 This is a schematic diagram showing the disassembled structure of an electronic device 200 provided in an embodiment of this application, with reference to... Figure 5 As shown, the electronic device 200 provided in this application embodiment includes: a display screen 220, a mid-frame 230, a housing 400, a motherboard 250, and a power supply 240.

[0094] A mid-frame 230, a motherboard 250, and a power supply 240 are disposed between the display screen 220 and the housing 400. The mid-frame 230 may include a mid-plate 231 and a surrounding frame comprising a left frame 232, a top frame 233, a right frame 234, and a bottom frame 235. The left frame 232, top frame 233, right frame 234, and bottom frame 235 form a ring, and the mid-plate 231 is disposed within and connected to these rings. The motherboard 250 and power supply 240 may be mounted on the mid-plate 231; for example, they may be mounted on the side of the mid-plate 231 facing the housing 400, or on the side of the mid-plate 231 facing the display screen 220.

[0095] It is readily understood that the electronic device 200 provided in this application includes, but is not limited to, the structures described above. For example, in some other embodiments, the middle frame 230 may not include the middle plate 231, and the frame of the middle frame 230 and the housing 400 may be an integral structure. In this embodiment, only the example of a separate structure for the middle frame 230 and the housing 400 is used for illustration.

[0096] The display screen 220, bezel, and housing 400 enclose a receiving cavity in which the necessary components of the electronic device 200 can be configured. For example, in some embodiments of this application, the electronic device 200 further includes multiple components, which can be mounted within the receiving cavity enclosed by the display screen 220, bezel, and housing 400. These multiple components may include processor internal memory, external memory interface, universal serial bus (USB) interface, charging management module, power management module, wires, communication module, audio module, speaker, receiver, microphone, headphone jack, sensor module, motor, indicator, and subscriber identification module (SIM) card interface, etc. The electronic device 200 may have more or fewer components than described above, may combine two or more components, or may have different component configurations. Each component can be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and / or application-specific integrated circuits.

[0097] The display screen 220 is used to display images and videos, etc. The display screen 220 can be a liquid crystal display (LCD), an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a flexible light-emitting diode (FLED) display screen, a quantum dot light-emitting diode (QLED) display screen, etc.

[0098] The power supply 240 can be connected to the motherboard 250 to provide power to the processor, internal memory, external memory, display screen 220, communication module, etc.

[0099] In this embodiment of the application, to achieve the shooting function, the electronic device 200 further includes at least one camera module 260 and a flash (not shown in the figure), wherein the camera module 260 can be a front-facing camera, a rear-facing camera, etc. The number of front-facing cameras and rear-facing cameras can be one or more. For example, as... Figure 5As shown, the camera module 260 includes a rear-facing camera. A first light-transmitting hole 410 is provided on the housing 400, and the camera module 260 is positioned corresponding to the first light-transmitting hole 410, allowing the camera module 260 to collect external light from the electronic device 200 through the first light-transmitting hole 410. The number of first light-transmitting holes 410 can be set according to specific needs; for example, the number of first light-transmitting holes 410 can be one or more. For example, as... Figure 5 As shown, the housing 400 has two first light-transmitting holes 410, one of which is configured to correspond to the camera module 260, and the other is configured to correspond to the flash. This application embodiment does not specify the number of first light-transmitting holes 410.

[0100] The camera module 260 is fixed inside the electronic device 200. Exemplarily, the camera module 260 can be fixed to the side of the middle plate 231 facing the housing 400 by means of threaded connection, snap-fit, welding, etc. In other embodiments, the camera module 260 can be fixed to the surface of the display screen 220 facing the housing 400 by means of threaded connection, snap-fit, welding, etc. In still other embodiments, the camera module 260 can be fixed to the surface of the motherboard 250 facing the housing 400 by means of threaded connection, snap-fit, welding, etc. Furthermore, the camera module 260 is also electrically connected to the motherboard 250, so that the camera module 260 can receive signals from the motherboard 250 and can also send signals to the motherboard 250.

[0101] When a user operates the electronic device 200 and needs to use the keyboard 311 on the keyboard unit 310, power needs to be supplied to the keyboard 311. To achieve portability and battery life for the electronic device component 100, refer to... Figure 3 As shown, the protective case 300 provided in this embodiment also includes a rechargeable battery 350, which can be disposed in the support portion 320. Of course, in some other embodiments of this application, the rechargeable battery 350 can also be disposed in the keyboard portion 310. The rechargeable battery 350 is electrically connected to the keyboard 311.

[0102] To enable charging of the rechargeable battery 350 within the protective case 300, refer to... Figure 6As shown, in some embodiments, a pogo pin connector 270 can be built into the electronic device 200, and the pogo pin connector 270 is electrically connected to the power supply 240 in the electronic device 200. A charging hole 420 is provided on the housing 400, and the charging hole 420 is a through hole to expose the pogo pin connector 270. The protective sleeve 300 is provided with a pogo pin interface, which is electrically connected to the rechargeable battery 350 in the protective sleeve 300. The power supply 240 in the electronic device 200 charges the rechargeable battery 350 in the protective sleeve 300 through contact between the pogo pin connector 270 and the pogo pin interface. A sealing ring 280 is provided on the inner wall of the charging hole 420, and the sealing ring 280 is located between the inner wall of the charging hole 420 and the pogo pin connector 270 to ensure the airtightness of the electronic device 200. When the housing 400 is a metal part, the sealing ring 280 also serves to prevent short circuit caused by contact between the pogo pin connector 270 and the housing 400.

[0103] However, in this method of charging the rechargeable battery 350 in the protective case 300, a charging hole 420 needs to be opened on the housing 400. The opening of the charging hole 420 hinders the overall continuity of the housing 400 and is not conducive to the aesthetic appearance of the electronic device 200.

[0104] To enable charging of the rechargeable battery 350 within the protective case 300, refer to... Figure 7 As shown, in some embodiments, a transmitting coil 10 can be built into the electronic device 200, and the transmitting coil is electrically connected to the power supply 240 in the electronic device 200. A receiving coil 20 is built into the protective case 300, and the receiving coil 20 is electrically connected to the rechargeable battery 350 in the protective case 300. The transmitting coil 10 and the receiving coil 20 constitute a charging coil structure, and the power supply 240 in the electronic device 200 charges the rechargeable battery 350 in the protective case 300 through electromagnetic induction. In this way, it is not necessary to open a charging hole 420 on the housing 400.

[0105] In this method of charging the rechargeable battery 350 within the protective case 300, the casing 400 needs to be made of a non-metallic material. For example, the casing 400 could be made of plastic, because a metallic casing 400 would create a magnetic shielding effect on the charging coil, weakening or distorting the magnetic field strength and thus affecting the performance of the charging coil. However, a non-metallic casing 400 would significantly reduce the aesthetics of the electronic device 200, hindering its visual appeal.

[0106] To address the aforementioned issues, this application provides a solution for wirelessly charging a rechargeable battery 350 in a protective case 300 for an electronic device 200. This solution allows the casing 400 of the electronic device 200 to be made of metal, and eliminates the need for additional through holes (charging holes 420) on the metal casing 400. This ensures the overall continuity of the casing 400, enhances the aesthetic appeal of the electronic device 200, and improves the user experience.

[0107] Let's first introduce the working principle of the charging coil: The charging coil works based on the principle of electromagnetic induction. A charging coil typically consists of a transmitting coil and a receiving coil. The transmitting coil is connected to a power supply. When the power supply is energized, the resulting alternating current generates a changing magnetic field in the transmitting coil. This magnetic field can penetrate into the receiving coil, inducing a current and thus enabling wireless charging. The principle of electromagnetic induction states that a conductor placed in a changing magnetic flux will generate an electromotive force (EMF). This EMF is called induced EMF. If this conductor is closed into a circuit, the EMF will drive the flow of electrons, forming an induced current. Specifically, when the alternating current in the transmitting coil generates a changing magnetic field, according to the principle of electromagnetic induction, this changing magnetic field will induce an EMF in the receiving coil, thereby generating an induced current.

[0108] refer to Figure 8 As shown, the electronic device 200 provided in this application embodiment further includes a decorative component assembly 500. The decorative component assembly 500 is fitted at the first light-transmitting hole 410 to decorate the outer surface of the electronic device 200, thereby improving its aesthetic appeal. In addition, the decorative component assembly 500 can also protect the internal functional components of the electronic device 200. For example, it can protect the flash, camera module, etc. To further improve the aesthetic appeal of the electronic device 200, in some embodiments of this application, the housing 400 is made of metal, forming a metal housing.

[0109] Figure 9 This is a schematic diagram illustrating the fit between the protective sleeve 300 and the housing 400 according to an embodiment of this application. Figure 9 This can be viewed as an electronic device 200 mounted on a protective sleeve 300 and observed from the outside of the protective sleeve 300. (Reference) Figure 9 As shown, Figure 9 The solid rectangle represents the protective sleeve 300, and the dashed rectangle represents the housing 400. The protective sleeve 300 has a second light-transmitting hole 370. Figure 9 The solid circle in the middle, Figure 9 (The middle is the visible state), the second light-transmitting hole 370 and the first light-transmitting hole 410 on the housing 400 (in the visible state) Figure 9 The dashed circle in the middle, Figure 9(The middle part is in an invisible state) corresponding to the assembly. The second light-transmitting hole 370 can be formed on the first part 321 of the support portion 320 of the protective sleeve 300 (e.g., ...). Figure 3 (as shown in the diagram). Of course, in some other embodiments of this application, the second light-transmitting hole 370 may also be formed on the second part 322 of the support portion 320 of the protective sleeve 300.

[0110] Figure 10 A partial cross-sectional view of the protective sleeve 300, decorative component assembly 500, and housing 400 provided in an embodiment of this application. Figure 1 , Figure 11 A perspective view of the decorative component assembly 500 and housing 400 provided in an embodiment of this application, with reference to... Figure 10 and Figure 11 As shown, the decorative component assembly 500 includes: a decorative component body 510, which is fixedly connected to the housing 400 to fix the decorative component body 510.

[0111] To reduce the assembly difficulty of the decorative component body 510 and minimize the impact of dimensional errors between the decorative component body 510 and the first light-transmitting hole 410, in some embodiments of this application, the decorative component body 510 includes a mounting portion 512 and a panel portion 511. The panel portion 511 is disposed directly opposite the first light-transmitting hole 410. The panel portion 511 can serve as a decorative panel of the decorative component assembly 500. Appearance design can be performed on the panel portion 511, thereby improving the aesthetic appeal of the electronic device 200. Additionally, the panel portion 511 can also shield the internal components of the electronic device 200, preventing users from observing the internal components from the outside of the electronic device 200, thus improving the user experience. The mounting portion 512 is disposed around the panel portion 511 and is connected to the panel portion 511. For example, as... Figure 10 As shown, the mounting portion 512 can be attached to the inner surface of the housing 400 by adhesive (e.g., using adhesive 700). Here, the inner surface of the housing 400 refers to the side of the housing 400 that faces away from the outside of the electronic device 200, and similarly, the outer surface of the housing 400 refers to the side of the housing 400 that faces the outside of the electronic device 200.

[0112] In some other embodiments of this application, the outer peripheral surface of the decorative component body 510 can also be connected to the inner wall of the first light-transmitting hole 410 by adhesive bonding to fix the decorative component body 510. This application does not specifically limit the connection and fixing method between the decorative component body 510 and the housing 400.

[0113] It should be noted that, in this embodiment, the shape of the first light-transmitting hole 410 can be a regular shape such as a circle, square, or triangle, or it can be an irregular shape. The shape and size of the panel portion 511 match the shape and size of the first light-transmitting hole 410. This embodiment does not specifically limit the shape and size of the first light-transmitting hole 410 and the panel portion 511; in this application, a circle is used as an example for illustration.

[0114] Continue to refer to Figure 10 and Figure 11 As shown, the decorative component assembly 500 also includes a first inductor coil assembly 520. The first inductor coil assembly 520 includes a first inductor coil 521. The first inductor coil 521 is disposed on the panel portion 511 and can be a transmitting coil, generating a changing magnetic field when energized. For example, an inverter can be disposed on the motherboard 250, and the first inductor coil 521 is connected to the inverter on the motherboard 250. The inverter converts the DC power output from the power supply 240 into AC power and supplies it to the first inductor coil 521. The first inductor coil 521 generates a changing magnetic field when AC power is applied. A second inductor coil 360 is disposed in the protective sleeve 300. The second inductor coil 360 can be a receiving coil. The second inductor coil 360 is coupled to the first inductor coil 521, sensing the changing magnetic field generated by the first inductor coil 521, generating an induced current to charge the rechargeable battery 350 in the protective sleeve 300. The second inductor coil 360 is disposed around the second light-transmitting hole 370. In some embodiments of this application, the second light-transmitting hole 370 can be concentrically arranged with the first light-transmitting hole 410, and the area of ​​the second light-transmitting hole 370 is set to be smaller than the area of ​​the first light-transmitting hole 410. At this time, a part of the protective sleeve 300 overlaps with the first light-transmitting hole 410. The second inductor coil 360 is arranged in this overlapping area and surrounds the second light-transmitting hole 370. In this way, the second inductor coil 360 is directly opposite the first inductor coil 521, thereby improving the charging efficiency of the electronic device 200 for the rechargeable battery 350 in the protective sleeve 300.

[0115] It is understood that the electronic device assembly 100 provided in this application integrates a first inductor coil 521 onto the decorative component assembly 500. The first inductor coil 521 is positioned directly opposite the first light-transmitting hole 410 of the electronic device 200. The coupling of the first inductor coil 521 with the second inductor coil 360 in the protective sleeve 300 enables the electronic device 200 to charge the rechargeable battery 350 within the protective sleeve 300. Furthermore, since the first inductor coil 521 is integrated into the decorative component assembly 500, the distance between the first inductor coil 521 and the internal electronic components of the electronic device 200 is increased, reducing mutual interference between them and improving the efficiency of charging the rechargeable battery 350 within the protective sleeve 300. Additionally, there is no need to create an additional charging hole 420 on the housing 400 of the electronic device 200, ensuring the overall continuity of the housing 400 and enhancing the aesthetic appeal of the electronic device 200. Meanwhile, since the first inductor coil 521 is positioned corresponding to the first light-transmitting hole 410, there is no casing 400 obstructing the connection between the first inductor coil 521 and the second inductor coil 360. Therefore, the casing 400 of the electronic device 200 can be made of metal. The metal casing 400 will not affect the coupling between the first inductor coil 520 and the second inductor coil 360, solving the problem that wireless charging can only be used with plastic casings. This allows for a fully metal casing 400, thereby improving the aesthetic appeal of the electronic device 200.

[0116] It is understood that in some embodiments of this application, the first inductor coil 521 may not be integrated on the decorative component assembly 500, but may be disposed inside the electronic device 200. For example, the electronic device 200 includes a first inductor coil assembly 520. The first inductor coil assembly 520 includes a first inductor coil 521. The first inductor coil 521 may be disposed on a structural component inside the middle plate 231, the main board 250, or the electronic device 200. Using a reference plane perpendicular to the axial direction of the first light-transmitting hole 410, the orthographic projection of the first inductor coil 521 onto the reference plane falls into the orthographic projection of the first light-transmitting hole 410 onto the reference plane.

[0117] In this way, the first inductor coil 521 can be coupled with the second inductor coil 360 in the protective case 300, so that the electronic device 200 can charge the rechargeable battery 350 in the protective case 300. Furthermore, it ensures the overall continuity of the housing 400, achieving a fully metal housing 400 and enhancing the aesthetic appeal of the electronic device.

[0118] It should be noted that in the description of the embodiments of this application, "parallel," "perpendicular," "equal," and "coplanar" include the described situation and situations similar to the described situation, where the range of similar situations is within an acceptable deviation range, wherein the acceptable deviation range is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "perpendicular" in the axial direction of the reference plane perpendicular to the first light-transmitting aperture 410 includes absolute perpendicularity and approximately perpendicularity, wherein the acceptable deviation range of approximately perpendicularity may be, for example, within ±10° or ±5°; similarly, "parallel" includes absolute parallelism and approximately parallelism, wherein the acceptable deviation range of approximately parallelism may be, for example, within ±10° or ±5°. "Equal" includes absolute equality and approximately equality, wherein the acceptable deviation range of approximately equality may be, for example, the difference between the two equalities being less than or equal to 5% of either one. For example, an angle of 180° between two components includes both absolute 180° and approximate 180°, where an acceptable deviation range for approximate 180° could be, for example, within ±10° or ±5°; similarly, an angle of 0° between two components includes both absolute 0° and approximate 0°, where an acceptable deviation range for approximate 0° could be, for example, within ±10° or ±5°. Similarly, an angle of 90° between two components includes both absolute 90° and approximate 90°, where an acceptable deviation range for approximate 90° could be, for example, within ±10° or ±5°.

[0119] It should be noted that in some embodiments of this application, the first inductor coil 521 in the electronic device 200 is a transmitting coil, and the second inductor coil 360 in the protective case 300 is a receiving coil, thereby enabling the electronic device 200 to charge the rechargeable battery 350 in the protective case 300. In other embodiments of this application, the first inductor coil assembly 521 in the electronic device 200 can also be a receiving coil, thereby enabling other devices to charge the electronic device 200 wirelessly. Of course, the second inductor coil 360 in the protective case 300 can also be a transmitting coil, thereby enabling the protective case 300 to charge other devices wirelessly.

[0120] Please continue to refer to this. Figure 10 and Figure 11As shown, a through-hole 5111 is provided on the panel portion 5111, which can avoid interference with functional components in the electronic device 200. For example, a flash can be installed at the through-hole 5111, and the light emitted by the flash can be emitted outside the electronic device 200 through the through-hole 5111. Another example is that a camera module 260 can be installed at the through-hole 5111, with the light-incident surface of the camera module 260 facing the through-hole 5111, allowing external light from the electronic device 200 to enter the light-incident surface of the camera module 260 through the through-hole 5111, thus enabling the camera module 260 to form an image. Yet another example is that an electroacoustic device, such as a speaker or microphone, can be installed at the through-hole 5111, allowing the electroacoustic device to input and output audio through the through-hole 5111. It is understood that the through-hole 5111 provided on the panel portion 511 can be one or more. Figure 10 The example below uses only through hole 5111 as an example.

[0121] The first inductor coil 521 is arranged around the through hole 5111. On the one hand, this allows the first inductor coil 521 to avoid obstructing the flash, camera module 260, and / or electroacoustic devices. On the other hand, it allows the first inductor coil 521 to maximize its coil area within the size constraint of the first light-transmitting hole 410, thereby improving the charging efficiency of the electronic device 200 for the rechargeable battery 350 in the protective case 300. Furthermore, it allows the through hole 5111 to be located as centrally as possible within the first light-transmitting hole 410, maximizing the receiving or transmitting angles of electronic devices such as the flash, camera module 260, or electroacoustic devices. The receiving or transmitting angles of the electronic devices can be referenced... Figure 10 As shown by the angle α between the dashed lines, Figure 10 The receiving angle or transmitting angle in the text refers to the receiving angle or transmitting angle when the protective cover 300 is fitted onto the electronic device 200. It is understandable that the receiving angle or transmitting angle will be larger when the protective cover 300 is removed.

[0122] Please continue to refer to this. Figure 10 and Figure 11 As shown, in some embodiments of this application, the decorative component assembly 500 further includes a light-transmitting sheet 530 sealed within the first light-transmitting hole 410. The light-transmitting sheet 530 is disposed on the side of the panel portion 511 facing the outside of the electronic device 200. Regarding the fixing method of the light-transmitting sheet 530, for example, the light-transmitting sheet 530 can be fixed to the outer surface of the housing 400 by a series of conventional fixing methods such as bonding and snap-fitting. For example... Figure 10As shown, the light-transmitting sheet 530 can be fixed to the inner wall of the first light-transmitting hole 410 through a series of conventional fixing methods such as bonding and snap-fitting. This application does not specifically limit the fixing method of the light-transmitting sheet 530. The light-transmitting sheet 530 can be used to protect the decorative component assembly 500 and the internal components of the electronic device 200, can also allow light to enter and exit the electronic device 200, and can also serve a decorative function for the appearance of the electronic device 200. The material of the light-transmitting sheet 530 can be glass, plastic, etc.

[0123] In some embodiments of this application, the light-transmitting sheet 530 has a light-transmitting area and a non-light-transmitting area. The light-transmitting area is provided corresponding to the through hole 5111, so that light from outside the electronic device 200 enters the camera module 260 through the light-transmitting area, or light emitted by the flash is emitted to the outside of the electronic device 200 through the light-transmitting area. The non-light-transmitting area is provided corresponding to at least a portion of the first inductor coil 521. That is, with a reference plane as a reference, at least a portion of the orthographic projection of the first inductor coil 521 in the reference plane falls into the orthographic projection of the non-light-transmitting area in the reference plane. The non-light-transmitting area can partially or completely block the first inductor coil 521, improving the aesthetic appearance of the electronic device 200. In some embodiments of this application, the non-light-transmitting area can be formed by an ink layer screen-printed on the side of the light-transmitting sheet 530 facing the outside of the electronic device 200 and / or screen-printed on the side of the light-transmitting sheet 530 away from the outside of the electronic device 200.

[0124] Please refer to Figure 11 As shown, in some embodiments of this application, the first light-transmitting hole 410 is circular, and the first inductor coil 520 is arranged in a ring around the through hole 5111. The ring-shaped first inductor coil 520 has an equal ring width, which allows the magnetic field generated by the first inductor coil 520 to have a regular magnetic field line distribution, which is beneficial to improving the charging efficiency of the electronic device 200 charging the rechargeable battery 350 in the protective case 300.

[0125] In some embodiments of this application, the first inductor coil 521 and the second inductor coil 360 are coils formed by coiling wires. This reduces the thickness of the first inductor coil 521 and the second inductor coil 360, thereby reducing the thickness of the electronic device 200 and the protective sleeve 300. The wires of the first inductor coil 521 and the second inductor coil 360 are wrapped with a ferrite protective layer, which reduces the impact of electromagnetic interference on the electronic device 200 and ensures the normal operation of the device.

[0126] Figure 12 A partial cross-sectional view of the protective sleeve 300, decorative component assembly 500, and housing 400 provided in an embodiment of this application. Figure 2 , Figure 13a A schematic diagram of the structure of the first inductor coil assembly 520 provided in an embodiment of this application. Figure 1 ,refer to Figure 12 and Figure 13a As shown, in some embodiments of this application, the first inductor coil assembly 520 further includes a magnetic shielding base 522. The magnetic shielding base 522 may be made of ferrite material and has a magnetoresistance effect, which can isolate the magnetic field. The first inductor coil 521 is disposed on the magnetic shielding base 522. For example, the first inductor coil 521 can be fixed to the magnetic shielding base 522 by a series of conventional fixing methods such as adhesive bonding and snap-fitting. The magnetic shielding base 522 is located on the side of the first inductor coil 521 facing away from the outside of the electronic device 200. The magnetic shielding base 522 can prevent mutual interference between the first inductor coil 521 and the electronic components inside the electronic device 200, thereby improving the charging efficiency of the electronic device 200 charging the rechargeable battery 350 in the protective case 300. The magnetic shielding base 522 may have clearance holes 5221 for the normal use of the camera module 260, flash, electroacoustic devices, etc.

[0127] Figure 13b A schematic diagram of the structure of the first inductor coil assembly 520 provided in an embodiment of this application. Figure 2 ,refer to Figure 13b As shown, in some embodiments of this application, the first inductor coil assembly 520 may further include an inverter 523. The first inductor coil 521 is connected to the inverter 523. The inverter 523 may be disposed inside the electronic device 200, for example, the inverter 523 may be disposed on the motherboard 250. The inverter 523 can convert the DC power output from the power supply 240 into AC power to supply the first inductor coil 521. The first inductor coil 521 generates a changing magnetic field after being supplied with AC power.

[0128] Figure 14 This is a schematic diagram showing the correspondence between the magnetic isolation base 522, the first inductor coil 521, and the second inductor coil 360 provided in an embodiment of this application. (Refer to...) Figure 14 As shown, in some embodiments of this application, a first receiving groove 5222 is provided on the magnetic shielding base 522, and a first inductor coil 521 is disposed in the first receiving groove 5222. Since the opening direction of the first receiving groove 5222 on the magnetic shielding base 522 faces the second inductor coil 360, the first receiving groove 5222 of the magnetic shielding base 522 can converge the magnetic signal generated by the first inductor coil 520, which can increase the induced current of the second inductor coil 360 disposed opposite the first inductor coil 521, thereby improving the charging efficiency of the electronic device 200 in charging the rechargeable battery 350 in the protective case 300. Furthermore, since the first inductor coil 521 is disposed in the first receiving groove 5222, the interference effect of the first inductor coil 521 on the internal electronic components of the electronic device 200 can be reduced, ensuring the normal operation of the electronic device 200.

[0129] Figure 15A schematic diagram of a portion of the housing 400 and the decorative component assembly 500 provided in an embodiment of this application. Figure 1 ,refer to Figure 15 As shown, in some embodiments of this application, the first light-transmitting hole 410 is circular, and the first inductor coil 521 is elliptical. Thus, electronic devices can be mounted on the panel portions 511 on both sides of the elliptical inductor coil 521 along its minor axis, optimizing the structural arrangement of the decorative component assembly 500. Furthermore, the coil area of ​​the first inductor coil 521 can be designed to be as large as possible within the dimensional constraints of the first light-transmitting hole 410, improving the charging efficiency of the electronic device 200 for the rechargeable battery 350 in the protective case 300. This allows the charging efficiency value between the first inductor coil 521 and the second inductor coil 360 to reach the minimum charging efficiency value (40%) for user experience. Here, the charging efficiency value between the first inductor coil 521 and the second inductor coil 360 refers to the ratio of the output energy of the first inductor coil 521 to the input energy of the second inductor coil 360.

[0130] Please continue to refer to this. Figure 15 As shown, in some embodiments of this application, mounting holes 610 are provided on both sides of the panel portion 511 in the direction of the short axis of the first inductor coil 521. Fasteners 600 can pass through the mounting holes 610 and be fixedly connected to the internal structural components of the electronic device 200. For example, fasteners 600 can pass through the mounting holes 610 and be connected to the middle plate 231, the main board 250, or other structural components of the electronic device 200, thereby improving the assembly stability of the panel portion 511 on the electronic device 200. It is understood that the closer the fastening point of the fastener 600 on the panel portion 511 is to the edge of the panel portion 511, the better the assembly stability of the panel portion 511. The elliptical ring-shaped first inductor coil 520 can serve as a clearance position for the fastener 600.

[0131] Figure 16 A schematic diagram of a portion of the housing 400 and the decorative component assembly 500 provided in an embodiment of this application. Figure 2 ,refer to Figure 16As shown, in some embodiments of this application, the first inductor coil 521 includes a first semicircular ring portion 5211, a second semicircular ring portion 5212, a first straight portion 5213, and a second straight portion 5214. The two ends of the first semicircular ring portion 5211 are respectively a first end and a second end, and the two ends of the second semicircular ring portion 5212 are respectively a third end and a fourth end. The first end and the third end are arranged opposite to each other, and the two ends of the first straight portion 5213 are respectively connected to the first end and the third end. The second end and the fourth end are arranged opposite to each other, and the two ends of the second straight portion 5214 are respectively connected to the second end and the fourth end. It can be understood that the first inductor coil 521 is racetrack-shaped. Compared to the standard elliptical ring-shaped first inductor coil 521, the racetrack-shaped first inductor coil 521 reduces the manufacturing difficulty of the first inductor coil 521 shape. In addition, the racetrack-shaped first inductor coil 521 has a larger central area, which allows more electronic devices, such as flashlights, electroacoustic devices, and camera modules 260, to be installed inside the electronic device 200.

[0132] Regarding the placement of the first inductor coil assembly 520 on the panel portion 511, for example, Figure 10 and Figure 12 As shown, the first inductor coil assembly 520 can be disposed on the side of the panel portion 511 facing the outside of the electronic device 200. For example, the first inductor coil assembly 520 can be disposed on the side of the panel portion 511 facing the outside of the electronic device 200 by means of adhesive bonding, snap-fit, or other methods. It is understood that in this way, since the first inductor coil assembly 520 is disposed on the side of the panel portion 511 facing the outside of the electronic device 200, the panel portion 511 can be made of metal, and there will be no shielding effect on the first inductor coil assembly 520 and the second inductor coil 360, which can also improve the aesthetic appearance of the electronic device 200. Of course, the panel portion 511 can also be made of plastic or other materials.

[0133] Figure 17 A partial cross-sectional view of the protective sleeve 300, decorative component assembly 500, and housing 400 provided in an embodiment of this application. Figure 3 ,refer to Figure 17As shown, in some embodiments of this application, a second receiving groove 5112 is provided on the side of the panel portion 511 facing the outside of the housing 400, and the first inductor coil 521 is disposed in the second receiving groove 5112. When the first inductor coil assembly 520 also includes a magnetic shielding seat 522, the magnetic shielding seat 522 can also be disposed in the second receiving groove 5112. In this way, the panel portion 511 can be made of metal, and will not have a shielding effect on the first inductor coil 520 and the second inductor coil 360, thereby improving the aesthetic appearance of the electronic device 200. Of course, the panel portion 511 can also be made of plastic or other materials. In addition, since the surface of the panel portion 511 facing the outside of the electronic device 200 is not limited by the height of the first inductor coil 520, the light-transmitting sheet 530 can be fixedly connected to the outer periphery of the panel portion 511 by adhesive (e.g., using adhesive 700), which can improve the assembly stability of the light-transmitting sheet 530 and also improve the sealing performance of the electronic device 200.

[0134] Figure 18 A partial cross-sectional view of an electronic device 200 provided in an embodiment of this application. Figure 1 ,refer to Figure 18 As shown, in some embodiments of this application, the first inductor coil assembly 520 can be disposed on the side of the panel portion 511 facing away from the outside of the electronic device 200. For example, the first inductor coil assembly 520 can be disposed on the side of the panel portion 511 facing away from the outside of the electronic device 200 by means of adhesive bonding, snap-fitting, etc. For example, as... Figure 18 As shown, in some embodiments of this application, the first inductor coil 521 is bonded to the side of the panel portion 511 facing away from the outside of the electronic device 200 using adhesive 700. This facilitates the fixation of the first inductor coil assembly 520 to the panel portion 511. In this manner, the panel portion 511 needs to be made of a non-metallic material to avoid the panel portion 511 causing magnetic shielding effects on the first inductor coil 520.

[0135] It should be noted that, Figure 16 In order to reduce the interference of the first inductor coil 521 on the camera module 260, the first inductor coil 521 and the camera module 260 are respectively disposed in different first light-transmitting holes 410. When the camera module 260 and the first inductor coil 521 need to be disposed in the same first light-transmitting hole 410, refer to Figure 19As shown, in some embodiments of this application, the electronic device 200 further includes an annular magnetic shielding sheet 540. The annular magnetic shielding sheet 540 is coaxially arranged with the through hole 5111, and the annular magnetic shielding sheet 540 encloses a receiving space, within which at least a portion of the camera module 260 is disposed. This reduces the interference of the first inductor coil 521 on the camera module 260, and reduces the effect of the first inductor coil 521 on the camera module 260 during operation. For example, it reduces the possibility of the first inductor coil 520 interfering with the camera module 260 during operation, thus preventing the camera module 260 from producing patterns or other defects in its image.

[0136] In some embodiments of this application, the first inductor coil 521 has a first end face and a second end face arranged opposite to each other along its axial direction, and the annular magnetic shielding sheet 540 has a third end face and a fourth end face arranged opposite to each other along its axial direction. In a first direction, the first end face and the second end face are located between the third end face and the fourth end face. The first direction is parallel to the axial direction of the through hole 5111. It can be understood that the upper top surface of the annular magnetic shielding sheet 540 in the thickness direction of the decorative component assembly 500 is higher than the upper top surface of the first inductor coil 521 in the thickness direction of the decorative component assembly 500, and the lower bottom surface of the annular magnetic shielding sheet 540 in the thickness direction of the decorative component assembly 500 is lower than the lower bottom surface of the first inductor coil 521 in the thickness direction of the decorative component assembly 500. This further reduces the interference of the first inductor coil 520 on the camera module 260 and reduces the effect of the first inductor coil 521 on the camera module 260 during operation.

[0137] For example, please refer to Figure 19 As shown, the annular magnetic shielding sheet 540 can be fixed to the side of the decorative part body 510 facing away from the electronic device 200 by a series of conventional methods such as bonding and snapping. For further example, please refer to... Figure 20 As shown, when the first inductor coil 520 is disposed on the side of the decorative body 510 facing the outside of the electronic device 200, the annular magnetic shielding sheet 540 can pass through the through hole 5111 and adhere to the inner wall of the through hole 5111.

[0138] Please refer to Figure 19 As shown, in this embodiment, the through-hole 5111 includes two holes. One through-hole 5111 is the light-inlet hole of the camera module 260, and the other through-hole 5111 is the light-outlet hole of the flash lamp 290. The flash lamp 290 can be fixed to the side of the decorative part body 510 away from the outside of the electronic device 200 using adhesive 700. Of course, referring to... Figure 21 As shown, in some embodiments of this application, the panel portion 511 may or may only have one through hole 5111, and the light-incident surface of the camera module 260 is disposed opposite to the through hole 5111.

[0139] It should be noted that the first inductor coil 521 has its own operating frequency. To achieve wireless charging, the first inductor coil 521 needs to use AC power of a specific frequency, which is the operating frequency of the first inductor coil 521. The camera module 260 also has its own acquisition frequency, which refers to the number of images acquired by the camera module 260 per second, usually expressed in Hertz (Hz). For example, an acquisition frequency of 140kHz means that the camera module 260 will acquire 140K images per second. When the operating frequency of the first inductor coil 521 is close to or equal to the acquisition frequency of the camera module 260, the first inductor coil 521 will affect the shooting of the camera module 260. To reduce the impact of the first inductor coil 521 on the shooting of the camera module 260 during operation, in some embodiments of this application, the absolute value of the difference between the operating frequency of the first inductor coil 521 and the operating frequency of the camera module 260 in the electronic device 200 can be set to be greater than or equal to 350kHz. For example, in a tablet computer, the operating frequency range of the camera module 260 is generally between 130kHz and 150kHz. The operating frequency of the first inductor coil 521 can adopt a conventional custom protocol. For instance, the first inductor coil 521 can adopt the operating frequency of the Near Field Communication (NFC) protocol, which is around 13.6MHz. Alternatively, the first inductor coil 521 can adopt a proprietary custom protocol, for example, the operating frequency of the first inductor coil 521 may be greater than or equal to 500kHz. This increases the difference between the operating frequency of the first inductor coil 521 and the sampling frequency of the camera module 260, reducing the impact of the first inductor coil 521 on the shooting of the camera module 260.
