Description

Technical Field

[0001] The present application relates to the technical field of terminal equipment, and in particular to an electronic device. Background Art

[0002] In order to increase the screen-to-body ratio of electronic devices and the overall aesthetics of the mobile phone screen, the front camera module is set as close to the casing as possible. The distance between the front camera module and the antenna embedded in the casing is getting smaller and smaller, resulting in an increasingly larger current coupled from the antenna to the front camera module. In order to prevent the coupled current from affecting the work of the camera module, a conductive cloth is provided to transfer the coupled current on the front camera module to the grounding structure, so that the coupled current on the front camera module is directly grounded.

[0003] However, the reliability of electrical connection between the conductive cloth and the grounding structure achieved through conductive glue is poor, resulting in the coupling current on the camera module being unable to be grounded smoothly. The coupling current affects the operation of the camera module, and at locations where the reliability of the electrical connection between the conductive cloth and the grounding structure is poor, the coupling current is easily radiated into the air, generating radiated spurious emission (RSE) current, which affects the wireless communication signal. Summary of the invention

[0004] The present application provides an electronic device. The electronic device includes a housing, a camera module, a first circuit board and an electrical connection structure. The camera module and the first circuit board are arranged in the housing, and the electrical connection structure is electrically connected to the camera module. The first circuit board is electrically connected to a ground terminal of the electronic device.

[0005] The electrical connection structure includes a metal spring and a screw, the first part of the metal spring is electrically connected to the camera module, the second part of the metal spring is at least partially fixedly connected to the first circuit board through the screw, and the camera module is electrically connected to the ground terminal of the electronic device through the metal spring, the screw and the first circuit board. Alternatively, the electrical connection structure includes a shielding cover, an insulating member and a first conductive sheet, the shielding cover is electrically connected to the first circuit board, the insulating member is fixedly connected to the shielding cover, the first part of the first conductive sheet is electrically connected to the camera module, at least part of the second part of the first conductive sheet is fixedly connected to a side of the insulating member away from the shielding cover, and the first conductive sheet, the insulating member and the shielding cover form a capacitor.

[0006] It is understandable that when the electrical connection structure includes a metal spring and a screw, the metal spring is fixed to the first circuit board by the screw, the connection strength between the metal spring and the first circuit board is better, the risk of the metal spring falling off the first circuit board due to external force collision is reduced, and the electrical connection reliability between the metal spring and the first circuit board is better. The coupling current on the camera module can be better grounded, reducing the risk of the camera module being affected by the coupling current and causing failure. It can also avoid the poor connection reliability between the metal spring and the first circuit board, which causes the coupling current to radiate into the air during transmission due to unstable electrical connection, generating radiated spurious emission (RSE) current, affecting the quality of wireless communication.

[0007] When the electrical connection structure includes a shielding cover, an insulating member and a first conductive sheet, the coupling current on the camera module is grounded through capacitive coupling. Compared with the scheme in which the first conductive sheet is directly electrically connected to the shielding cover through a conductive glue, the coupling current on the camera module is directly grounded. The conductive glue uses insulating materials mixed with metal particles, and the metal particles are used for conduction. On the one hand, metal particles are easily oxidized when exposed to air. On the other hand, metal particles will generate heat during the electrical transmission process, and the heat further accelerates the oxidation of metal particles. After the metal particles are oxidized, the resistivity of the conductive glue is higher, and the bonding ability of the conductive glue will also decrease, resulting in a decrease in the reliability of the electrical connection between the first conductive sheet and the shielding cover. The insulating member in the technical solution of the present application is not easy to age, the electrical connection reliability between the first conductive sheet and the shielding cover is better, and the coupling current on the camera module can be better grounded, reducing the risk of failure of the camera module caused by the coupling current. It can also avoid the coupling current from radiating into the air due to unstable electrical connection during transmission, generating RSE current, and affecting the quality of wireless communication.

[0008] In a possible implementation manner, the insulating member is insulating glue.

[0009] It can be understood that the insulating member can serve as both an insulating medium of the capacitor and a connecting structure between the first conductive sheet and the shielding cover, thereby eliminating the need for an additional connecting structure, which is beneficial to the miniaturization of the electronic device.

[0010] In a possible implementation, the facing area between the insulating member and the shielding cover is greater than 20 square millimeters.

[0011] It can be understood that the facing area between the insulating member and the shielding cover refers to the projection area of ​​the insulating member on the shielding cover along the first direction. The first direction refers to the direction in which the second portion 432 of the first conductive sheet faces the shielding cover. In this way, when the first conductive sheet is fixed to the shielding cover through the insulating member, the connection area between the first conductive sheet and the shielding cover is larger, the connection reliability between the first conductive sheet and the shielding cover is better, and the coupling current on the camera module can be better grounded.

[0012] In a possible implementation, the thickness of the insulating member is in the range of 0.03 mm to 0.05 mm, which can reduce the risk of the insulating member being broken down when the coupling current is large.

[0013] In a possible implementation, the thickness of the first conductive sheet is in the range of 0.03 mm to 0.05 mm. In this way, the thickness of the electronic device in the Z-axis direction can be smaller, which is conducive to the thinness of the electronic device.

[0014] In a possible implementation, the first conductive sheet is nickel-plated conductive cloth, gold-plated conductive cloth, carbon-plated conductive cloth or aluminum foil fiber composite cloth; or the first conductive sheet is copper foil.

[0015] It is understandable that the thickness of the conductive cloth or copper foil is small and the weight is light, and the space inside the electronic device occupied is also small. The thickness of the electronic device in the Z-axis direction can be small, which is conducive to the thinness of the electronic device. In addition, the shape of the conductive cloth or copper foil is convenient for cutting and has a certain flexibility, and can be well attached to the camera module, so that the first conductive sheet and the camera module have a larger contact area, better connection reliability, and lower impedance during the conduction process.

[0016] In a possible implementation, the metal spring is a nickel-plated stainless steel sheet or a gold-plated stainless steel sheet. In this way, the strength of the metal spring is better, and the risk of the metal spring falling off from the first circuit board is lower.

[0017] In a possible implementation, the thickness of the metal dome is in the range of 0.2 mm to 0.3 mm.

[0018] In a possible implementation, the second portion of the metal spring is provided with a first through hole, the first circuit board is provided with a second through hole, the screw is fixed in the first through hole and the second through hole, and the metal spring is against the grounding end of the first circuit board. In this way, the connection reliability between the metal spring and the first circuit board is better. The coupling current on the camera module can be reliably transmitted to the grounding end of the first circuit board through the two structures of the metal spring and the screw at the same time.

[0019] In one possible implementation, the electrical connection structure also includes a second conductive sheet, a portion of the second conductive sheet is electrically connected to the camera module, another portion of the second conductive sheet is electrically connected to the metal spring sheet, and the camera module is electrically connected to the metal spring sheet via the second conductive sheet.

[0020] It can be understood that by providing a second conductive sheet, the electrical connection area between the metal spring sheet and the camera module can be increased, thereby improving the reliability of the electrical connection between the metal spring sheet and the camera module.

[0021] In one possible implementation, the camera module includes a lens assembly, a shell and a second circuit board. The shell and the second circuit board are fixedly connected. The shell and the second circuit board enclose a storage space, and the lens assembly is disposed in the storage space.

[0022] The first portion of the first conductive sheet is electrically connected to the second circuit board. Alternatively, the first portion of the metal spring sheet is electrically connected to the second circuit board.

[0023] It can be understood that compared with the fixed connection between the first part of the first conductive sheet and the shell of the camera module, the first part of the first conductive sheet is fixedly connected to the side of the second circuit board away from the shell, and the second circuit board has fewer peripheral structures, which facilitates the connection and assembly between the first conductive sheet and the camera module.

[0024] Similarly, compared with the fixed connection between the first part of the metal shrapnel and the shell of the camera module, the first part of the metal shrapnel is fixedly connected to the side of the second circuit board away from the shell, and the peripheral structure of the second circuit board is relatively small, which facilitates the connection and assembly between the metal shrapnel and the camera module.

[0039] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0040] Figure 1 It is a structural diagram of an implementation of an electronic device 1000 provided in an embodiment of the present application.

[0041] The electronic device 1000 may include, but is not limited to, a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, a vehicle-mounted device, a wearable device, augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses, a VR helmet or a drone, etc., and may be an electronic device 1000 with a camera function. Figure 1 The electronic device 1000 shown in FIG. 1 is introduced by taking a mobile phone as an example.

[0042] It should be noted that Figure 1 The following figures and the related drawings only schematically illustrate some components of the electronic device 1000, and the actual shapes, sizes, positions and structures of these components are not limited to the following. Figure 1 As defined in the following figures. For ease of description, the width direction of the electronic device 1000 is defined as the X-axis. The length direction of the electronic device 1000 is defined as the Y-axis. The thickness direction of the electronic device 1000 is defined as the Z-axis. It is understood that the coordinate system setting of the electronic device 1000 can be flexibly set according to specific actual needs.

[0043] Figure 2 yes Figure 1 An exploded schematic diagram of an embodiment of an electronic device 1000 is shown. Figure 3 yes Figure 1 The electronic device 1000 is shown as a partial cross-sectional view of an embodiment along the section line AA.

[0044] like Figure 2 and Figure 3 As shown, the electronic device 1000 may include a housing 100, a camera module 200, a mainboard 300, an electrical connection structure 400, a screen 500, and an antenna 600. The screen 500 and the antenna 600 are installed in the housing 100. The screen 500 and the housing 100 enclose an internal space 1001 of the electronic device 1000. The camera module 200, the electrical connection structure 400, and the mainboard 300 are all installed in the internal space 1001 of the electronic device 1000.

[0045] The screen 500 can be used to display images, videos, etc. In some embodiments, the screen 500 can also have a touch sensing function, and the touch sensing function of the screen 500 is used to sense the user's touch action to achieve human-computer interaction. Exemplarily, the screen 500 can be a liquid crystal display (LCD), an organic light-emitting diode (OLED) display, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display, a flexible light-emitting diode (FLED) display, a Mini-LED display, a Micro-LED display, a Micro-OLED display, a quantum dot light-emitting diode (QLED) display, etc.

[0046] In some implementations, when the electronic device 1000 is a device of some other form factor, the electronic device 1000 may not include the screen 500 .

[0047] Exemplarily, the housing 100 may include a middle frame 101 and a back cover 102. The back cover 102 is fixedly connected to the middle frame 101. Exemplarily, the back cover 102 may be fixed to the middle frame 101 by adhesive. The screen 500 may be located on a side of the middle frame 101 away from the back cover 102. In this case, the screen 500 and the back cover 102 are respectively located on both sides of the middle frame 101. The screen 500, the middle frame 101 and the back cover 102 together enclose the internal space of the electronic device 1000.

[0048] In some embodiments, the back cover 102 and the middle frame 101 can be connected by bonding, welding, snap connection, screw connection, etc. In some embodiments, the back cover 102 and the middle frame 101 can also be an integrally formed structure, that is, the back cover 102 and the middle frame 101 are an integral structure.

[0049] The camera module 200 can be a front camera module or a rear camera module. This application takes the camera module 200 as a front camera module as an example for introduction. The lighting surface of the camera module 200 faces the screen 500. Exemplarily, the screen 500 may include a display area 501 and a light-transmitting area 502. The display area 501 is used to display images. The light-transmitting area 502 is used to allow light outside the electronic device 1000 to enter the interior of the electronic device 1000 through the light-transmitting area. The camera module 200 can be arranged opposite to the light-transmitting area 502. The camera module 200 can collect ambient light entering the interior of the electronic device 1000. The light-transmitting area is not limited to Figure 1 The circle shown in .

[0050] Exemplarily, the camera module 200 may be a common camera module (i.e., the optical axis direction of the camera module 200 is the thickness direction of the electronic device 1000, i.e., the Z-axis direction). In some embodiments, the camera module 200 may also be a periscope camera module (i.e., the optical axis direction of the camera module 200 may be any direction on the XY plane). The drawings of this application are all described by taking the camera module 200 as a common camera module as an example.

[0051] In some embodiments, when the camera module 200 is a front camera module 200, the camera module 200 can be disposed on the top of the electronic device 1000. The top of the electronic device 1000 refers to the end of the electronic device 1000 that is away from the ground when the user is using the electronic device 1000. Similarly, the light-transmitting area 502 of the screen 500 can also be disposed on the top of the screen 500. Exemplarily, the distance L1 between the light-transmitting area 502 and the housing 100 can be in the range of 0 mm to 0.2 mm. The distance L2 between the camera module 200 and the housing 100 is less than L1. It is understandable that the light-transmitting area 502 is positioned as close to the housing 100 as possible, so that the screen 500 can have more area for displaying images, and the user has a better experience of using the electronic device.

[0052] Exemplarily, the mainboard 300 may include a first circuit board 310 and a first electronic component 320. The first electronic component 320 may be fixedly connected to the first circuit board 310. The first circuit board 310 may serve as a bearing structure for the first electronic component 320. The first circuit board 310 may be fixedly connected to the middle frame 101. In some embodiments, the first circuit board 310 may also be fixedly mounted on the back cover 102 of the housing 230.

[0053] Exemplarily, the first electronic component 320 may be an active device such as a chip, or may be a passive device such as a capacitor, an inductor, a resistor, etc. It is understandable that those skilled in the art can select the number and type of the first electronic components 320 and their arrangement on the circuit board, so as to form a motherboard 300 with specific functions with the circuit board.

[0054] The antenna 600 can be used to transmit and / or receive electromagnetic waves to achieve a radiation function. In some embodiments, the electronic device 1000 may further include a communication module. The communication module may integrate one or more first electronic components 320 of at least one communication processing module, and the communication module may be used to perform frequency modulation, amplification, filtering, and other processing on the antenna 600 radiation signal. Exemplarily, the communication module may be provided on the mainboard 300.

[0055] In some embodiments, the antenna 600 may be fixedly connected to the housing 100. For example, the antenna 600 may be embedded in the middle frame 101, or attached to the inner surface of the middle frame 101. The inner surface of the middle frame 101 faces the inside of the electronic device 1000. In some embodiments, the antenna 600 may also be embedded in the back cover 102.

[0056] In some embodiments, the antenna 600 may be disposed on the top of the housing 100. The top of the housing 100 refers to the end of the housing 100 that is away from the ground when the user uses the electronic device 1000. It is understood that there are fewer electronic devices near the top of the housing 100, and the radiation function of the antenna 600 is less interfered.

[0057] The electrical connection structure 400 can be electrically connected to the camera module 200. The electrical connection structure 400 can be electrically connected to the first circuit board 310. The camera module 200 can be electrically connected to the first circuit board 310 through the electrical connection structure 400. When the first circuit board 310 is electrically connected to the ground terminal of the electronic device 1000, the camera module 200 can be electrically connected to the ground terminal of the electronic device 1000 through the electrical connection structure 400. The electrical connection structure 400 can be used to reliably ground the interference current of the camera module 200.

[0058] Exemplarily, the camera module 200 may include some metal structures. When the camera module 200 is close to the antenna 600, the metal structures on the camera module 200 may couple with the working current of the antenna 600 to generate current (hereinafter, the current generated by the metal structures on the camera module 200 due to coupling with the antenna 600 is referred to as coupling current). The coupling current on the camera module 200 may be transferred to the ground terminal of the mainboard 300 through the electrical connection structure 400. By setting the electrical connection structure 400, on the one hand, it is possible to prevent the coupling current from interfering with the operation of the camera module 200, and on the other hand, it is possible to prevent the coupling current on the camera module 200 from interfering with the antenna 600 in transmitting and / or receiving electromagnetic waves.

[0059] In some embodiments, the middle frame 101 can be used as a ground terminal of the electronic device 1000, and the first circuit board 310 can be electrically connected to the middle frame 101. In this way, the coupling current on the camera module 200 can be grounded via the electrical connection structure 400, the first circuit board 310, and the middle frame 101 in sequence.

[0060] In some embodiments, the electronic device 1000 may further include an electronic device (not shown). The electronic device may be installed in the internal space of the electronic device 1000. Exemplarily, the electronic device may include a battery, a processor, a communication module, an audio module, a speaker, a microphone, and a subscriber identification module (SIM) card.

[0061] In some embodiments, the electronic device 1000 may further include a circuit board bracket (not shown). Exemplarily, the circuit board bracket may be fixedly connected to the first circuit board 310. The circuit board bracket is used to prevent the structure provided on the first circuit board 310 (such as the first electronic component 320 or other modules) from interfering with other devices in the internal space of the electronic device 1000, so as to facilitate the assembly of the electronic device 1000.

[0062] Several specific implementations of electrically connecting the camera module 200 to the ground terminal of the electronic device 1000 via the electrical connection structure 400 will be described below in conjunction with the accompanying drawings.

[0063] Figure 4 yes Figure 2 A schematic diagram of an exploded view of an embodiment of a camera module 200 is shown in FIG. Figure 5 yes Figure 4 A cross-sectional view of an embodiment of the camera module 200 shown in FIG. 2 is taken at section line BB.

[0064] like Figure 4 and Figure 5As shown, the camera module 200 may include a lens 210, a motor 220, a housing 230 and a circuit module 240. The lens 210 may be a fixed focus lens 210, an auto focus (AF) lens, or a zoom lens, etc. The lens 210 of the present application is described by taking an AF lens as an example.

[0065] Exemplarily, the housing 230 may include an upper cover 232 and a side wall 233. The upper cover 232 and one end of the side wall 233 are connected. In some embodiments, the housing 230 may be made of a metal material, such as stainless steel, aluminum alloy, etc.

[0066] The lens 210 may be fixedly connected to the motor 220. The motor 220 may be used to drive the lens 210 to focus. Exemplarily, the motor 220 may be provided with a light-transmitting channel 221. The lens 210 may be accommodated in the light-transmitting channel 221 and fixedly connected to the motor 220. The lens 210 and the motor 220 constitute a lens assembly 290 of the camera module 200.

[0067] Exemplarily, the motor 220 may be an AF-OIS motor 220. That is, the motor 220 may be used to achieve auto focus (AF) by controlling the movement of the lens 210 along the optical axis direction of the lens 210 (in this embodiment, the optical axis direction of the lens 210 is the Z-axis direction). When the lens 210 is in the center position, the lens 210 may move toward the light incident side or toward the circuit module 240. That is, the center position of the lens 210 may be understood as the initial position of the lens 210 before focusing.

[0068] The motor 220 can also control the movement of the lens 210 along a plane perpendicular to the optical axis (in this embodiment, the plane perpendicular to the optical axis is the XY plane). In this way, when the camera module 200 collects ambient light, if the electronic device 1000 is shaken in the XY plane due to external force, the movement of the lens 210 in the XY plane can be controlled by the motor 220 to offset the shaking stroke of the lens 210 in the XY plane, so as to avoid or reduce the position deviation of the lens 210 caused by shaking. In other words, the camera module 200 of the present application can control the movement of the lens 210 in the XY plane by the motor 220, thereby realizing the optical image stabilization (OIS) of the camera module 200 and improving the imaging quality of the camera module 200. In some embodiments, the motor 220 can also be an AF motor, an OIS motor, a voice coil motor, a shape memory alloy motor, a piezoelectric ceramic motor, a stepper motor motor or a micro motor (MEMS) motor, etc.

[0069] The circuit module 240 may include a photosensitive chip 241, a second electronic component 243, and a second circuit board 242. The photosensitive chip 241 and the second electronic component 243 may be fixedly connected to the second circuit board 242. The second circuit board 242 may be used to carry the photosensitive chip 241 and the second electronic component 243. The photosensitive chip 241 may be used to collect ambient light and convert the image information carried by the ambient light into an electrical signal. The second electronic component 243 may be an active device such as a chip, or may be a passive device such as a capacitor, an inductor, a resistor, or a filter. The second electronic component 243 may be used to drive the motor 220 to work.

[0070] Exemplarily, the second circuit board 242 may include a first surface 2421 and a second surface 2422, and the first surface 2421 and the second surface 2422 are arranged back to back. Among them, the first surface 2421 is a side surface of the second circuit board 242 facing the lens 210. The second electronic component 243, the photosensitive chip 241, the motor 220 and the side wall 233 of the housing 230 can be fixedly connected to the first surface 2421 of the second circuit board 242. The upper cover 232 can be fixedly connected to one end of the side wall 233 away from the second circuit board 242. In this way, the upper cover 232, the side wall 233 and the second circuit board 242 can enclose the accommodating space 231. The lens 210 and the motor 220 can be arranged in the accommodating space 231. In this way, the camera module 200 can form a whole for easy installation.

[0071] In some embodiments, the second surface 2422 of the second circuit board 242 may serve as a ground terminal of the second circuit board 242 .

[0072] In some embodiments, the second circuit board 242 may include a dielectric layer (not shown) and a metal layer (not shown). The metal layer is embedded in the dielectric layer. The dielectric layer can be used to protect and insulate the metal layer. The metal layer can be used to transmit electrical signals. The photosensitive chip 241 and the second electronic component 243 can be electrically connected to the metal layer. The metal layer of the second circuit board 242 can serve as a ground terminal of the second circuit board 242.

[0073] In some embodiments, the second circuit board 242 may be a printed circuit board (PCB).

[0074] like Figure 3 and Figure 4 As shown, the electronic device 1000 may further include a flexible circuit board 250. One end of the flexible circuit board 250 may be electrically connected to the second circuit board 242, and the other end may be electrically connected to the main board 300. The signal of the second circuit board 242 (such as the signal of the photosensitive chip 241) may be transmitted to the main board 300 through the flexible circuit board 250. Exemplarily, the flexible circuit board 250 may be electrically connected to the metal layer of the second circuit board 242.

[0076] like Figure 3 , Figure 6 and Figure 7 As shown, the electrical connection structure 400 may include a shielding cover 410, an insulating member 420, and a first conductive sheet 430. The first portion 431 of the first conductive sheet 430 may be at least partially fixedly connected to the camera module 200. The first portion 431 of the first conductive sheet 430 may be electrically connected to the camera module 200. Exemplarily, the first portion 431 of the first conductive sheet 430 may be at least partially fixedly connected to a side of the second circuit board 242 away from the lens 210. The first portion 431 of the first conductive sheet 430 may be electrically connected to the second circuit board 242.

[0077] In some embodiments, the first portion 431 of the first conductive sheet 430 may be electrically connected to the second circuit board 242 via a screw. In some embodiments, the first portion 431 of the first conductive sheet 430 may also be electrically connected to the second circuit board 242 via a conductive adhesive.

[0078] In some embodiments, the first conductive sheet 430 may be a conductive cloth. For example, nickel-plated conductive cloth, gold-plated conductive cloth, carbon-plated conductive cloth or aluminum foil fiber composite cloth. In some embodiments, the first conductive sheet 430 may also be a copper foil. It is understandable that the thickness of the conductive cloth or copper foil is small and the weight is light, and the internal space of the electronic device 1000 occupied is also small. The thickness of the electronic device 1000 in the Z-axis direction can be small, which is conducive to the thinness of the electronic device 1000. In addition, the shape of the conductive cloth or copper foil is convenient for cutting, has a certain flexibility, can be relatively well attached to the camera module 200, can make the first conductive sheet 430 and the camera module 200 have a larger contact area, better connection reliability, and lower impedance during the conduction process.

[0079] In some embodiments, the thickness of the first conductive sheet 430 may be in the range of 0.03 mm to 0.05 mm. In this way, the thickness of the electronic device 1000 in the Z-axis direction may be small, which is conducive to the thinness of the electronic device 1000.

[0080] In some embodiments, the housing 230 of the camera module 200 may be electrically connected to the second circuit board 242. When the first portion 431 of the first conductive sheet 430 is electrically connected to the second circuit board 242, the housing 230 of the camera module 200 may be electrically connected to the first portion 431 of the first conductive sheet 430 through the second circuit board 242, so that the coupling current on the housing 230 may be conducted to the first conductive sheet 430 through the second circuit board 242.

[0081] like Figure 8 Shown is Figure 5 The structure shown in FIG. is an enlarged schematic diagram of an embodiment at D. The camera module 200 may also include an electrical connector 260. The electrical connector 260 may be used to transmit the coupling current on the camera module 200. The electrical connector 260 may include one or more forms of a metal spring, a screw, a cable, a metal trace, a flexible circuit board, a conductive solder layer, a conductive adhesive, etc. The housing 230 of the camera module 200 may be electrically connected to the second circuit board 242 through the electrical connector 260. Exemplarily, when the electrical connector 260 is a conductive solder layer, the housing 230 of the camera module 200 may be fixedly connected to the second circuit board 242 by welding, and the coupling current generated on the housing 230 may be conducted to the second circuit board 242 through the electrical connector 260. For another example, when the electrical connector 260 is a screw, the housing 230 may be fixedly connected to the second circuit board 242 by a screw (not shown), and the coupling current generated by the housing 230 may be conducted to the second circuit board 242 by the screw.

[0082] In some embodiments, the number of electrical connectors 260 may be one or more. When the camera module 200 includes multiple metal structural members that are coupled with the antenna 600 and generate coupling current, multiple electrical connectors 260 may be provided, and the multiple electrical connectors 260 are respectively connected to the multiple structural members that generate coupling current included in the camera module 200 in a one-to-one correspondence, thereby grounding the coupling current generated by different structures of the camera module 200 as much as possible.

[0083] In some embodiments, the first portion 431 of the first conductive sheet 430 may be at least partially connected to the second surface 2422 of the second circuit board 242. In some embodiments, the first portion 431 of the first conductive sheet 430 may also be at least partially connected to the flexible circuit board 250. In this way, the connection area between the first conductive sheet 430 and the camera module 200 is larger, and the connection reliability is better.

[0084] In some embodiments, the first portion 431 of the first conductive sheet 430 may also be electrically connected to the upper cover 232 of the camera module 200. It is understood that the position where the first conductive sheet 430 is connected to the camera module 200 may be adjusted according to the internal installation scheme of the camera module 200 in the electronic device 1000. At the same time, the multiple structural members generating coupling current in the camera module 200 may conduct the coupling current to the structure electrically connected to the first conductive sheet 430 through the electrical connector 260.

[0085] The shielding cover 410 may be electrically connected to the ground terminal of the electronic device 1000. For example, Figure 6 and Figure 7 As shown, the shielding cover 410 can be electrically connected to the ground terminal of the first circuit board 310. The shielding cover 410 can be used to shield the first electronic component 320 to be shielded to prevent the first electronic component 320 from being subjected to electromagnetic interference. Exemplarily, the shielding cover 410 can have an accommodating space 411. The first electronic component 320 that needs electromagnetic shielding can be located in the accommodating space 411.

[0086] In some embodiments, the back cover 102 may be a ground terminal of the electronic device 1000. The shielding cover 410 may also be electrically connected to the back cover 102.

[0087] In some embodiments, the shielding cover 410 may be made of a metal conductive material, such as aluminum alloy, stainless steel, or nickel silver.

[0088] Exemplarily, the insulating member 420 can be fixedly connected to the shielding cover 410, and the insulating member 420 can be an insulating material. The second portion 432 of the first conductive sheet 430 can be at least partially fixedly connected to the side of the insulating member 420 away from the shielding cover 410. The first conductive sheet 430, the insulating member 420 and the shielding cover 410 form a capacitor. The first conductive sheet 430 and the shielding cover 410 are insulated. The shielding cover 410 is electrically connected to the first circuit board 310. In this way, the coupling current on the camera module 200 can be coupled to the shielding cover 410 through the first conductive sheet 430, and conducted to the ground terminal of the electronic device 1000 through the shielding cover 410 and the first circuit board 310 for grounding.

[0089] It is understandable that, compared to the scheme in which the first conductive sheet 430 is directly electrically connected to the shielding cover 410 through the conductive glue, and the coupling current of the camera module 200 is directly grounded, the scheme in the embodiment of the present application can form a capacitor between the first conductive sheet 430, the insulating member 420 and the shielding cover 410, and the coupling current on the camera module 200 is grounded through capacitor coupling, which can reduce the impedance of the coupling current during the electrical transmission process. In addition, the conductive glue uses insulating materials mixed with metal particles, and the metal particles are used for conduction. On the one hand, the metal particles are easily oxidized when exposed to air, and on the other hand, the metal particles will generate heat during the electrical transmission process, and the heat further accelerates the oxidation of the metal particles. After the metal particles are oxidized, the resistivity of the conductive glue is higher, and the bonding ability of the conductive glue will also decrease, resulting in a decrease in the reliability of the electrical connection between the first conductive sheet 430 and the shielding cover 410. Compared with the solution of attaching the first conductive sheet 430 to the shielding cover 410 through conductive adhesive, the technical solution in the embodiment of the present application is that the coupling current on the camera module 200 is grounded through capacitive coupling, the insulating member 420 is not easy to age, and the connection reliability between the first conductive sheet 430 and the shielding cover 410 is better. The electrical connection reliability between the first conductive sheet 430 and the shielding cover 410 is better, the coupling current on the camera module 200 can be better grounded, reducing the risk of the camera module 200 being affected by the coupling current and causing failure. It can also avoid the poor connection reliability between the first conductive sheet 430 and the shielding cover 410, which causes the coupling current to radiate into the air during transmission due to unstable electrical connection, generating radiated spurious emission (RSE) current, and affecting the quality of wireless communication.

[0090] Exemplarily, the first circuit board 310 may include a dielectric layer 311 and a metal layer 312. The metal layer 312 is embedded in the dielectric layer 311. The dielectric layer 311 is made of insulating material, and the metal layer 312 is made of conductive metal. The first electronic component 320 can be electrically connected to the metal layer 312, and the metal layer 312 can be used for electrical signal transmission and grounding between the first electronic component 320. The metal layer 312 can serve as the grounding terminal of the first circuit board 310 and be electrically connected to the housing 100. Exemplarily, the middle frame 101 can be the grounding terminal of the electronic device 1000. The first circuit board 310 can be fixedly connected to the middle frame 101 by screws. The screws can pass through the metal layer 312 and be electrically connected to the middle frame 101, and the first circuit board 310 can be electrically connected to the middle frame 101 by screws. In this way, the shielding cover 410 can be electrically connected to the grounding terminal of the electronic device 1000 through the first circuit board 310. Exemplarily, the shielding cover 410 can be electrically connected to the metal layer 312 of the first circuit board 310 by welding.

[0091] In some embodiments, the insulating member 420 may be made of insulating glue. The second portion 432 of the first conductive sheet 430 may be at least partially fixedly connected to the shielding cover 410 through the insulating member 420. In this way, the insulating member 420 can be used as both an insulating medium of the capacitor and a connecting structure between the first conductive sheet 430 and the shielding cover 410, which can save the need for an additional connecting structure, thereby facilitating the miniaturization of the electronic device 1000.

[0092] In some embodiments, the electrical connection structure 400 may also include insulating tape, a portion of which is fixedly connected to the second portion 432 of the first conductive sheet 430 away from the side of the shielding cover 410, and another portion of which is fixedly connected to the shielding cover 410, thereby achieving a fixed connection between at least a portion of the second portion 432 of the first conductive sheet 430 and the shielding cover 410.

[0093] It can be understood that, compared with the solution of forming a capacitor between the first conductive sheet 430, the insulating member 420 and the first circuit board 310, the first conductive sheet 430, the insulating member 420 and the shielding cover 410 form a capacitor, while achieving the grounding of the coupling current of the camera module 200, there is no need to occupy the space of the first circuit board 310 for setting the first electronic component 320, which is conducive to reducing the volume of the electronic device 1000. In addition, the shielding cover 410 has a large area, which is conducive to setting a larger area of ​​the insulating member 420, thereby increasing the connection reliability between the first conductive sheet 430 and the shielding cover 410. The coupling current on the camera module 200 can be better grounded, thereby reducing the risk of the coupling current radiating into the air during the transmission process and generating radiated spurious emission (RSE) current due to the poor connection reliability between the first conductive sheet 430 and the shielding cover 410.

[0094] In some embodiments, the facing area between the insulating member 420 and the shielding cover 410 is greater than 20 square millimeters. The facing area between the insulating member 420 and the shielding cover 410 refers to the projection area of ​​the insulating member 420 on the shielding cover 410 along the first direction. The first direction refers to the direction in which the second portion 432 of the first conductive sheet 430 faces the shielding cover 410. In this way, when the first conductive sheet 430 is fixedly connected through the insulating member 420 and the shielding cover 410, the connection area between the first conductive sheet 430 and the shielding cover 410 is larger, the connection reliability between the first conductive sheet 430 and the shielding cover 410 is better, and the coupling current on the camera module 200 can be better grounded, thereby avoiding the poor connection reliability between the first conductive sheet 430 and the shielding cover 410, which causes the coupling current to radiate into the air during transmission due to unstable electrical connection, generating radiated spurious emission (RSE) current, and affecting the quality of wireless communication.

[0095] In some embodiments, the material of the insulating member 420 may be any one of polycarbonate (PC), polyvinyl chloride (PVC) or polyethylene (PE).

[0096] In some embodiments, the resistivity of the insulating member 420 may be in the range of 10 9 Ohm﹒m to 10 22 In this way, the risk of the insulating member 420 being broken down when the coupling current is large can be reduced.

[0097] In some embodiments, the thickness of the insulating member 420 may be in the range of 0.03 mm to 0.05 mm, so as to reduce the risk of the insulating member 420 being broken down when the coupling current is large.

[0098] like Figure 9a Shown is Figure 1 FIG. 1 is a partial cross-sectional view of another embodiment of the electronic device 1000 at the section line AA.

[0099] like Figure 9aAs shown, the electrical connection structure 400 may include a metal spring 440. A first portion 441 of the metal spring 440 may be at least partially fixedly connected to the camera module 200. The first portion 441 of the metal spring 440 may be electrically connected to the camera module 200. A second portion 442 of the metal spring 440 may be electrically connected to a ground terminal of the electronic device 1000. Exemplarily, the ground terminal of the electronic device 1000 may be electrically connected to a ground terminal of the first circuit board 310, and the second portion 442 of the metal spring 440 may be electrically connected to a ground terminal of the first circuit board 310, wherein the second portion 442 of the metal spring 440 may be at least partially welded to the first circuit board 310.

[0100] In some embodiments, the electrical connection structure 400 may further include a screw 450, such as Figure 9b Shown is Figure 1 FIG. 1 is a partial cross-sectional view of yet another embodiment of the electronic device 1000 at the section line AA. Fig.10 yes Figure 9b Schematic diagram of the assembly of the partial structure shown in another angle.

[0101] like Figure 9b and Fig.10 As shown, the first part 441 of the metal dome 440 can be electrically connected to the camera module 200. The first part 441 of the metal dome 440 can be at least partially fixedly connected to the camera module 200. The second part 442 of the metal dome 440 can be at least partially fixedly connected to the first circuit board 310 by screws. The second part 442 of the metal dome 440 can be electrically connected to the first circuit board 310 by screws. The first circuit board 310 is electrically connected to the ground terminal of the electronic device 1000. Through the metal dome 440, the screw 450, and the first circuit board 310, the camera module 200 can be electrically connected to the ground terminal of the electronic device 1000.

[0102] Exemplarily, the second portion 442 of the metal dome 440 can be electrically connected to the ground terminal of the first circuit board 310 through a screw. The ground terminal of the first circuit board 310 can be electrically connected to the ground terminal of the electronic device 1000. In this way, the coupling current on the camera module 200 can be finally conducted to the ground terminal of the electronic device 1000 through the metal dome 440, the screw 450, and the ground terminal of the first circuit board 310.

[0103] It is understandable that, compared with the solution in which the metal shrapnel 440 is fixedly connected to the first circuit board 310 by means of conductive glue, in this embodiment, the metal shrapnel 440 is fixed to the first circuit board 310 by means of screws 450, and the connection strength between the metal shrapnel 440 and the first circuit board 310 is better, thereby reducing the risk of the metal shrapnel 440 falling off the first circuit board 310 due to external force collision. The second part 442 of the metal shrapnel 440 can be electrically connected to the first circuit board 310 by means of screws. The electrical connection reliability between the metal shrapnel 440 and the first circuit board 310 is better, and thus the coupling current on the camera module 200 can be reliably grounded via the metal shrapnel 440, the screws 450, and the first circuit board 310, which not only avoids the coupling current interfering with the operation of the camera module 200, but also avoids the coupling current from radiating RSE current into the air during transmission due to unstable electrical connection, thereby affecting the wireless communication signal.

[0104] Exemplarily, the first portion 441 of the metal dome 440 may be at least partially fixedly connected to a side of the second circuit board 242 of the camera module 200 away from the housing 230. The first portion 441 of the metal dome 440 may be electrically connected to the second circuit board 242.

[0105] Exemplarily, the first portion 441 of the metal dome 440 may be electrically connected to the second circuit board 242 via a screw.

[0106] In some embodiments, the electrical connection structure 400 may further include a second conductive sheet (not shown), a portion of the second conductive sheet may be electrically connected to the camera module 200, another portion of the second conductive sheet may be electrically connected to the metal spring sheet 440, and the camera module 200 may be electrically connected to the metal spring sheet 440 via the second conductive sheet. Exemplarily, the second conductive sheet may be a conductive cloth, such as a nickel-plated conductive cloth, a gold-plated conductive cloth, a carbon-plated conductive cloth, or an aluminum foil fiber composite cloth.

[0107] It is understandable that by providing a second conductive sheet, the electrical connection area between the metal spring sheet 440 and the camera module 200 can be increased, thereby improving the reliability of the electrical connection between the metal spring sheet 440 and the camera module 200 .

[0108] Fig.11 yes Figure 9b A schematic structural diagram of an implementation scheme of the structure shown in FIG.

[0109] like Figure 9b and Fig.11As shown, the second portion 442 of the metal spring 440 may be provided with a first through hole 4421, the first circuit board 310 may be provided with a second through hole 313, and the grounding terminal of the first circuit board 310 may be exposed in the second through hole 313. The screw 450 may be fixed in the first through hole 4421 and the second through hole 313. The metal spring 440 may abut against the grounding terminal of the first circuit board 310. In this way, the coupling current of the camera module 200 may be transmitted to the grounding terminal of the first circuit board 310 via the metal spring 440 and the screw 450.

[0110] In some embodiments, the middle frame 101 can be used as a ground terminal of the electronic device 1000, and the middle frame 101 can also be provided with a third through hole 103, and the screw 450 can be fixed in the first through hole 4421, the second through hole 313 and the third through hole 103. The coupling current of the camera module 200 can be electrically connected via the metal spring 440, the screw 450, the first circuit board 310 and the middle frame 101.

[0111] In some embodiments, the electrical connection structure 400 may further include a foam 460. The foam 460 may be disposed between the metal spring 440 and the first circuit board 310. It is understood that the connection strength between the screw 450 and the first circuit board 310 may be enhanced by disposing the foam 460.

[0112] In some embodiments, the metal spring 440 may be a nickel-plated stainless steel sheet or a gold-plated stainless steel sheet. The metal spring 440 has good electrical conductivity, and the impedance of the metal spring 440 is small during the grounding of the coupling current of the camera module 200.

[0113] In some embodiments, the thickness of the metal spring 440 is in the range of 0.2 mm to 0.3 mm. In this way, the thickness of the electronic device 1000 in the Z-axis direction can be small, which is conducive to the thinness of the electronic device 1000.

[0114] It should be noted that in the embodiments of the present application, the same parts as those in the previous embodiments will not be repeated.

[0115] The present application introduces several electronic devices 1000 through the accompanying drawings. The electronic device 1000 includes a housing 230, a camera module 200, a first circuit board 310 and an electrical connection structure 400, wherein the electrical connection structure 400 is electrically connected to the camera module 200, and the first circuit board 310 is electrically connected to the ground terminal of the electronic device 1000.

[0116] The electrical connection structure 400 may include a metal dome 440 and a screw 450, wherein a first portion 441 of the metal dome 440 is electrically connected to the camera module 200, and a second portion 442 of the metal dome 440 is at least partially fixedly connected to the first circuit board 310 via the screw 450, and the camera module 200 is electrically connected to the ground terminal of the electronic device 1000 via the metal dome 440, the screw 450, and the first circuit board 310. It is understandable that the metal dome 440 is fixed to the first circuit board 310 via the screw 450, and the connection strength between the metal dome 440 and the first circuit board 310 is better, which reduces the risk of the metal dome 440 falling off the first circuit board 310 due to external force collision, and the electrical connection reliability between the metal dome 440 and the first circuit board 310 is better. The coupling current of the camera module 200 can be better grounded, reducing the risk of the camera module 200 being affected by the coupling current and causing failure. It can also prevent the coupling current from radiating into the air due to unstable electrical connection during transmission, generating radiated spurious emission (RSE) current and affecting the quality of wireless communication.

[0117] Alternatively, the electrical connection structure 400 may include a shielding cover 410, an insulating member 420, and a first conductive sheet 430, wherein the shielding cover 410 is electrically connected to the first circuit board 310, the insulating member 420 is fixedly connected to the shielding cover 410, the first portion 431 of the first conductive sheet 430 is electrically connected to the camera module 200, at least part of the second portion 432 of the first conductive sheet 430 is fixedly connected to a side of the insulating member 420 away from the shielding cover 410, and the first conductive sheet 430, the insulating member 420, and the shielding cover 410 form a capacitor. It can be understood that, compared with the scheme in which the first conductive sheet 430 is directly electrically connected to the shielding cover 410 through a conductive adhesive, and the coupling current of the camera module 200 is directly grounded, the first conductive sheet 430, the insulating member 420, and the shielding cover 410 form a capacitor, and the coupling current on the camera module 200 is grounded through capacitor coupling, which can reduce the impedance of the coupling current during electrical transmission. In addition, the conductive adhesive uses insulating materials mixed with metal particles, and the metal particles are used for conduction. On the one hand, metal particles are easily oxidized when exposed to air, and on the other hand, metal particles generate heat during electrical transmission, and the heat further accelerates the oxidation of metal particles. After the metal particles are oxidized, the resistivity of the conductive adhesive is higher, and the bonding ability of the conductive adhesive is also reduced, resulting in a decrease in the reliability of the electrical connection between the first conductive sheet 430 and the shielding cover 410. In the technical solution of the present application, the coupling current of the camera module 200 is grounded through capacitive coupling, the insulating member 420 is not easy to age, and the connection reliability between the first conductive sheet 430 and the shielding cover 410 is better. The electrical connection reliability between the first conductive sheet 430 and the shielding cover 410 is better, and the coupling current on the camera module 200 can be better grounded, reducing the risk of failure of the camera module 200 due to the coupling current. It can also avoid the poor connection reliability between the first conductive sheet 430 and the shielding cover 410, which causes the coupling current to radiate into the air during transmission due to unstable electrical connection, generating radiated spurious emission (RSE) current, affecting the quality of wireless communication.
