DETAILED DESCRIPTION

[0058] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0059] In the description of this application, it should be understood that the terms "length", "width", "thickness", "top", "bottom", "inside", "outside", "up", "down", "left", "right", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on this application.

[0060] The terms "first," "second," "third," and "fourth," etc., are used solely for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. For example, the terms "first pushing portion" and "second pushing portion" are used solely to distinguish between the different pushing portions and do not define their order. The first pushing portion could also be named the second pushing portion, and the second pushing portion could also be named the first pushing portion without departing from the scope of the various described embodiments. Furthermore, the terms "first," "second," "third," and "fourth," etc., do not necessarily define the features being referred to as different.

[0061] In this application, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0062] In this application, "and / or" is simply a way to describe the relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0063] It should be noted that, in this application, words such as "in one embodiment," "exemplarily," and "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "in one embodiment," "exemplarily," or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "in one embodiment," "exemplarily," and "for example" is intended to present the relevant concepts in a concrete manner.

[0064] In order to make the purpose, technical solutions and advantages of this application more clear, this application is further described in detail below with reference to the accompanying drawings and embodiments.

[0065] During the use of traditional electronic devices, since the antenna and camera module are both installed inside the electronic device, the antenna can easily cause interference to the camera module when transmitting signals, resulting in interference phenomena such as screen distortion, lag, and freezing in the camera module, resulting in a poor user experience.

[0066] Electronic devices also have conductive components such as brackets, motherboards, decorative elements (decorative components), heat sinks, and shielding covers. When an antenna transmits a radio frequency signal, the wavelength of the electromagnetic wave radiated by it corresponds to the size of the conductive component. For example, when the size of the conductive component is equal to or close to 1 / 4 or 1 / 2 of the wavelength of the electromagnetic wave, the conductive component couples the electromagnetic wave radiated by the antenna, generating standing waves in the conductive component.

[0067] Standing waves include changing magnetic fields and changing electric fields. The changing electric field causes the electrons in the conductive part to move, which in turn generates a changing current on the surface of the conductive part that is conducted along the propagation direction of the standing wave. The changing current generates a changing magnetic field. The current is strongest at the location of the strong magnetic field on the surface of the conductive part, and the changing magnetic field generates a changing electric field. As the above process is repeated, the standing wave propagates to the vicinity of the camera module.

[0068] Standing waves have strong electric / magnetic field points along their propagation direction. Conductive components have locations corresponding to these strong electric / magnetic field points, which easily lead to extremely strong near-field coupling between the conductive components at these locations and the camera module. The electric / magnetic field carrying the image information signal on the camera module's MIPI line and the standing wave's electric / magnetic field will superimpose on each other, forming a superimposed signal. When the superimposed signal is transmitted to the SoC (System on Chip) for demodulation, the SoC cannot demodulate the superimposed signal, causing interference problems in the camera module.

[0069] On the other hand, the camera module, the housing of the electronic device and the screen module may also be conductive. When the antenna emits a radio frequency signal, the wavelength of the electromagnetic wave radiated by it corresponds to the size of the camera module, the electronic device and the screen module. For example, when the sizes of the camera module, the electronic device and the screen module are equal to or close to 1 / 4 or 1 / 2 of the wavelength of the electromagnetic wave, the camera module, the electronic device and the screen module couple the electromagnetic waves radiated by the antenna, and standing waves are generated in the camera module, the electronic device and the screen module.

[0070] In view of this, embodiments of the present application provide an anti-interference structure, a housing assembly, and an electronic device, which can improve the above-mentioned technical problems.

[0071] The electronic device provided in the embodiments of the present application can be a mobile phone, a tablet computer, a wearable device (such as a watch), a personal digital assistant (PDA), a laptop computer, an augmented reality (AR) or virtual reality (VR) device, an in-vehicle device, or other electronic device with an antenna and a camera module, but is not limited thereto. In the embodiments of the present application, the electronic device is described as a mobile phone.

[0072] Please refer to Figures 1, 2, 3, 4 and 5. Figure 1 is a three-dimensional assembly diagram of the shell assembly 100 provided in an embodiment of the present application, Figure 2 is a three-dimensional exploded diagram of the shell assembly 100 shown in Figure 1, Figure 3 is a three-dimensional diagram of the bracket in the body assembly shown in Figure 1, Figure 4 is a model diagram of the anti-interference structure in the shell assembly 100 shown in Figure 1, and Figure 5 is a schematic diagram of the relative positions of the bracket, the first conductive loss component 40 and the mainboard 50 in the anti-interference structure shown in Figure 4.

[0073] In a first aspect, a first embodiment of the present application provides an anti-interference structure for an electronic device. The electronic device further includes a housing 70 , which is connected to the anti-interference structure.

[0074] The anti-interference structure includes an antenna 10, a camera module 20, and a conductive member 30. The conductive member 30 is located in the space between the antenna 10 and the camera module 20. The electromagnetic wave radiated by the antenna 10 can excite a first standing wave propagating along a first direction on the conductive member 30. The first standing wave includes a first electric field. The first electric field can cause the conductive member 30 to generate a first current conducted along the first direction toward one side of the first standing wave.

[0075] The anti-interference structure includes a first conductive loss component 40, which is located on the side of the conductive component 30 facing the first standing wave. The first conductive loss component 40 is made of a current loss material. Alternatively, the conductive component 30 facing the first standing wave is made of a current loss material.

[0076] It should be noted that antenna 10 is a component on an electronic device used to receive and transmit radio frequency signals and can radiate electromagnetic waves. For example, antenna 10 can be a 5G Wi-Fi antenna or a 5G N78 antenna. Furthermore, antenna 10 may have multiple frequency bands. Antenna 10 transmits radio frequency signals and radiates electromagnetic waves.

[0077] As an example, the antenna 10 can be integrated into the housing 70 of an electronic device. Specifically, the antenna 10 can be located within the middle frame 71 of the housing 70. This not only better protects the antenna 10 but also prevents interference from other components, thereby improving signal reception quality. Furthermore, the middle frame 71 provides stable support and fixation for the antenna 10. Integrating the antenna 10 within the middle frame 71 of the housing 70 improves the overall aesthetics and integrity of the mobile phone.

[0078] The camera module 20 may include a camera for lighting imaging. The camera module 20 may be further divided into a front camera module 20 and a rear camera module 20 , and multiple of these modules may be provided.

[0079] In addition, the conductive member 30 can be made of metal or other conductive materials. Specifically, the conductive member 30 can include a bracket of the electronic device, a motherboard 50, a decorative piece (Deco), a heat sink, and a shielding cover. In this embodiment, the conductive member 30 is a bracket.

[0080] The conductive member 30 is located in the space between the antenna 10 and the camera module 20. Specifically, the antenna 10 defines a first plane (not shown), and the camera module 20 defines a second plane (not shown). Both planes are perpendicular to the first direction. The conductive member 30 is located in the space between the first and second planes, not necessarily on the line connecting the antenna 10 and the camera module 20.

[0081] In this embodiment, the anti-interference structure includes a first conductive lossy component 40 . The first conductive lossy component 40 is located on the side of the conductive component 30 facing the first standing wave. Specifically, the first conductive lossy component 40 may be located between the conductive component 30 and the mainboard 50 .

[0082] The first conductive loss member 40 can be connected to the conductive member 30 by bonding, welding, clamping, or threading. Alternatively, a current loss material can be directly deposited onto the conductive member 30 to form the first conductive loss member 40. A current loss material is a material capable of dissipating current and possessing the ability to absorb current. Specifically, current is absorbed within the current loss material, where the energy of the current is converted into other forms of energy without generating a magnetic field.

[0083] For example, a current-dissipating material can be a low-conductivity material that converts electrical current into heat. Conductivity is a measure of a material's ability to carry electrical current. It is defined by Ohm's law as the ratio of current density to electric field strength, and conductivity is the reciprocal of resistivity. The SI unit of conductivity is Siemens per meter (S / m).

[0084] Specifically, the first conductive loss component 40 may be disposed only on one side of the conductive component 30 where the first standing wave is located. When the first standing wave is generated on the entire surface of the conductive component 30, the first conductive loss component 40 may cover the conductive component 30.

[0085] For example, please refer to Figure 4. In this embodiment, the conductive member 30 is located in the space between the antenna 10 and the camera module 20. The electromagnetic waves radiated by the antenna 10 can excite a first standing wave propagating along a first direction on the conductive member 30. The first direction is the Y direction in the figure. The first magnetic field direction of the first standing wave is parallel to the X direction in the figure. The direction of the first electric field of the first standing wave is parallel to the Z direction in the figure. The conduction direction of the first current is along the Y direction in the figure.

[0086] In other embodiments, the conductive member 30 is made of a current loss material on the side facing the first standing wave.

[0087] It can be understood that the material of the portion of the conductive element 30 facing the first standing wave is a current loss material; or, the material of the entire conductive element 30 is a current loss material.

[0088] It should be noted that the current loss material can be one of an alloy material, a semiconductor material, and a clay material, so that the first conductive loss member 40 can be conveniently manufactured using the current loss material. Specifically, the alloy material can be nickel-chromium, chromium-nickel-iron, manganese-copper, or constantan; the semiconductor material can be silicon or germanium; and the clay material can be carbon clay. The current loss material can absorb current energy and convert it into heat energy.

[0089] Among them, along the first direction, when the electromagnetic wave radiated by the antenna 10 excites a first standing wave propagating along the first direction on the conductive part 30, the current loss material can convert part of the first current generated by the first electric field of the first standing wave on the conductive part 30 into heat energy, thereby preventing it from forming a changing first magnetic field again. The intensity of the first magnetic field of the first standing wave gradually weakens, and the intensity of the first electric field of the first standing wave also weakens accordingly, thereby weakening the overall intensity of the first standing wave, and then shortening the propagation distance of the first standing wave, avoiding the superposition of the first electric field / first magnetic field and the electric field / magnetic field carrying the image information signal on the MIPI line of the camera module 20, and effectively improving the interference problem caused by the first standing wave to the camera module 20.

[0090] It can be understood that, from a holistic perspective, since part of the energy of the first standing wave is converted into other forms of energy through the current loss material, the overall intensity of the first standing wave is weakened, thereby shortening the propagation distance of the first standing wave, effectively improving the interference problem caused by the first standing wave to the camera module 20.

[0091] From the above, it can be seen that the anti-interference structure provided in the embodiment of the present application includes a first conductive loss part 40, and the first conductive loss part 40 is located on the side of the conductive part 30 facing the first standing wave. The material of the first conductive loss part 40 is a current loss material, or the material of the part of the conductive part 30 facing the first standing wave is a current loss material. Therefore, when the electromagnetic wave radiated by the antenna 10 excites the first standing wave propagating along the first direction on the conductive part 30, the current loss material can convert the first current generated by the first electric field of part of the first standing wave on the conductive part 30 into heat energy, thereby preventing it from forming a changing first magnetic field again, thereby weakening the intensity of the first magnetic field and the intensity of the first electric field of the first standing wave, thereby weakening the overall intensity of the first standing wave, and further shortening the propagation distance of the first standing wave, avoiding the superposition of the first electric field / first magnetic field and the electric field / magnetic field carrying the image information signal on the MIPI line of the camera module 20, and effectively improving the interference problem caused by the first standing wave to the camera module 20.

[0092] The anti-interference structure provided in the embodiment of the present application can achieve efficient decoupling of the camera module 20 and the antenna 10, thereby solving the anti-interference problem of the camera module 20; compared with the grounding methods such as conductive cloth and conductive foam required for traditional grounding, the anti-interference structure provided in the embodiment of the present application can save space and avoid RSE (Radiated Spurious Emiss) and other problems; the anti-interference structure provided in the embodiment of the present application is applicable to the decoupling problem of any frequency band and has no defect of frequency band limitation; the anti-interference structure provided in the embodiment of the present application is also beneficial for solving the clutter problem of the antenna 10.

[0093] It is understandable that components such as the camera module 20, screen module 80, PCB (Printed Circuit Board) flexible board and power supply in the electronic device will also radiate electromagnetic waves. For example, the image information signal carried on the MIPI line of the camera module 20 is transmitted in the form of electromagnetic waves. The electromagnetic waves radiated by components such as the camera module 20, screen module 80, PCB flexible board and power supply may also excite standing waves on the conductive member 30. The excited standing waves are coupled to the antenna 10, affecting the antenna 10 from receiving electromagnetic waves emitted by the base station, which will cause the receiving sensitivity of the antenna 10 to deteriorate. The anti-interference structure provided in the embodiment of the present application can also be used to improve the interference problem of components such as the camera module 20, screen module 80, PCB flexible board and power supply that can radiate electromagnetic waves on the antenna 10. The principle is consistent with the principle of improving the interference problem on the camera module 20.

[0094] 2 , 3 and 4 , in the first embodiment, within a temperature range of -50° C. to 200° C., the electrical conductivity of the current loss material along the first direction is less than or equal to 8000 S / m.

[0095] By adopting the above scheme, the current loss material can convert a larger portion of the first current into heat energy, thereby weakening the intensity of the first magnetic field and the intensity of the first electric field of the first standing wave, thereby weakening the overall intensity of the first standing wave and shortening the propagation distance of the first standing wave.

[0096] Understandably, the temperature range of -50°C to 200°C represents the typical operating temperature range for electronic devices. Whether conductivity exhibits directional characteristics depends on the specific material and circumstances. For general materials, conductivity is isotropic, meaning the conductivity measured in different directions is the same. Therefore, for these materials, conductivity exhibits no directional characteristics. In this case, ensuring that the conductivity of the current loss material is less than or equal to 8000 S / m in all directions is sufficient.

[0097] Optionally, in order to enable the current loss material to convert a larger portion of the first current into heat energy, thereby further weakening the intensity of the first magnetic field of the first standing wave, the conductivity of the current loss material along the first direction is less than or equal to 3000 S / m.

[0098] Optionally, the anti-interference structure includes a first conductive loss component 40, which is located on the side of the conductive component 30 facing the first standing wave. The material of the first conductive loss component 40 is current loss material, and the distance between the first conductive loss component 40 and the conductive component 30 is less than or equal to 2 mm.

[0099] By adopting the above solution, the relative positions of the first conductive loss component 40 and the conductive component 30 can be easily set, and a larger portion of the first current can be converted into heat energy through the first conductive loss component 40 .

[0100] In this embodiment, the first conductive loss member 40 is disposed on the outer surface of the conductive member 30. This configuration facilitates the placement of the first conductive loss member 40 and enables a larger portion of the first current to be converted into heat energy through the first conductive loss member 40.

[0101] Please refer to Figures 6 and 7. Figure 6 is a simulation diagram of the antenna 10-MIPI (Mobile Industry Processor Interface) isolation in a traditional shell assembly 100, and Figure 7 is a simulation diagram of the alternating distribution of electric and magnetic fields on the conductive member 30 in the traditional shell assembly 100.

[0102] As can be seen from FIG6 , by calculating the antenna 10 - MIPI isolation, it can be found that there are some frequencies of the antenna 10 with poor isolation, and the relevant frequencies can easily cause interference to the camera module 20 .

[0103] As can be seen from Figure 7, the main physical mechanism for the poor isolation of relevant frequency points is the excitation of the standing wave mode of the entire machine architecture, which excites the first standing wave on the conductive member 30. This is because compared with the non-standing wave mode state, the strong electric field / magnetic field point of the standing wave mode will cause the near-field coupling between the bracket and the antenna 10 to be greatly enhanced.

[0104] Please refer to Figures 8 and 9. Figure 8 is a comparative simulation diagram of the electric field strength of the conductive member 30 in the shell assembly 100 provided in Example 1 of the present application in the first conductive loss member 40 with conductivities of 1000 S / m and 3000 S / m respectively, and the conductive member 30 in the traditional shell assembly 100 under the standing wave mode. Figure 9 is a comparative diagram of the isolation between the conductive member 30 in the shell assembly 100 shown in Figure 1 and the anti-interference structure in the traditional shell assembly 100.

[0105] As can be seen from Figure 8, the first conductive loss component 40 weakens the intensity of the first electric field of the first standing wave in the standing wave mode, and as the conductivity decreases, the electric field strength becomes weaker and weaker, which plays a role of electromagnetic loss and can effectively improve the interference problem caused by the first standing wave to the camera module 20.

[0106] As can be seen from FIG. 9 , as the conductivity of the first conductive loss element 40 decreases, the isolation value also continuously improves.

[0107] Please refer to Figures 10 and 11. Figure 10 is a schematic diagram of the relative positions of the bracket, the first conductive loss component 40 and the mainboard 50 in the anti-interference structure provided in Example 2 of the present application. Figure 11 is a comparison diagram of the isolation between the conductive component 30 in the shell assembly 100 shown in Figure 10 and the anti-interference structure in the traditional shell assembly 100.

[0108] Different from the first embodiment, in this embodiment, the first conduction loss component 40 is located between the bracket and the mainboard 50 , and there are gaps between the first conduction loss component 40 and the bracket, and between the first conduction loss component 40 and the mainboard 50 .

[0109] The curves in Figure 11 are, from top to bottom, the isolation curve in the traditional shell assembly 100, the antenna 10-MIPI isolation curve when the first conductive loss part 40 is ordinary metal, the antenna 10-MIPI isolation curve when the conductivity of the first conductive loss part 40 is 3000 S / m, and the antenna 10-MIPI isolation curve when the conductivity of the first conductive loss part 40 is 1000 S / m.

[0110] As can be seen from Figure 11 , the solution in which the first conductive lossy component 40 is located between the bracket and the mainboard 50, and gaps are present between the first conductive lossy component 40 and the bracket, and between the first conductive lossy component 40 and the mainboard 50, also has a certain effect on improving isolation. The improvement in isolation becomes more pronounced as the conductivity of the first conductive lossy component 40 decreases.

[0111] In this embodiment, the first conductive loss component 40 is adhered to the bracket, so there is a gap between the two.

[0112] Please refer to Figures 12 and 13. Figure 12 is a schematic diagram of the relative positions of the bracket and the mainboard 50 in the anti-interference structure provided in Example 3 of the present application. Figure 13 is a comparison diagram of the isolation between the conductive part 30 in the shell assembly 100 shown in Figure 12 and the anti-interference structure in the traditional shell assembly 100.

[0113] Different from the first embodiment, in this embodiment, the bracket is made of a current loss material.

[0114] The curves in FIG13 are, from top to bottom, the isolation curve in the traditional housing assembly 100, the antenna 10-MIPI isolation curve when the conductivity of the bracket is 3000 S / m, and the antenna 10-MIPI isolation curve when the conductivity of the bracket is 1000 S / m.

[0115] As can be seen from Figure 11, using a current loss material as the entire support also has a certain effect on improving isolation. The improvement in isolation becomes more pronounced as the conductivity of the support decreases.

[0116] Please refer to FIG. 14 , which is a schematic diagram of the relative positions of the bracket, the first conductive loss component 40 and the mainboard 50 in the anti-interference structure provided in the fourth embodiment of the present application.

[0117] Different from the first embodiment, in this embodiment, the first conductive loss component 40 is located on the side of the conductive component 30 facing the first standing wave. Specifically, the first conductive loss component 40 may be located on the side of the conductive component 30 facing away from the main board 50 .

[0118] By adopting the above-mentioned scheme, when the electromagnetic wave radiated by the antenna 10 excites a first standing wave propagating along the first direction on the conductive part 30, the current loss material can convert part of the first current generated by the first electric field of the first standing wave on the conductive part 30 into heat energy, thereby preventing it from forming a changing first magnetic field again, thereby weakening the intensity of the first magnetic field and the intensity of the first electric field of the first standing wave, thereby weakening the overall intensity of the first standing wave, and further shortening the propagation distance of the first standing wave, effectively improving the interference problem caused by the first standing wave on the camera module 20.

[0119] Please refer to FIG. 15 , which is a schematic diagram of the relative positions of the bracket, the first conductive loss component 40 and the mainboard 50 in the anti-interference structure provided in the fifth embodiment of the present application.

[0120] Different from the fourth embodiment, in this embodiment, the first conductive loss component 40 is located on the side of the conductive component 30 facing the first standing wave. Specifically, the first conductive loss component 40 can be located on the side of the conductive component 30 facing away from the main board 50, and a gap can exist between the first conductive loss component 40 and the conductive component 30.

[0121] By adopting the above-mentioned scheme, when the electromagnetic wave radiated by the antenna 10 excites a first standing wave propagating along the first direction on the conductive part 30, the current loss material can convert part of the first current generated by the first electric field of the first standing wave on the conductive part 30 into heat energy, thereby preventing it from forming a changing first magnetic field again, thereby weakening the intensity of the first magnetic field and the intensity of the first electric field of the first standing wave, thereby weakening the overall intensity of the first standing wave, and further shortening the propagation distance of the first standing wave, effectively improving the interference problem caused by the first standing wave on the camera module 20.

[0122] Please refer to Figures 1, 2, 3, 4, 16 and 17. Figure 16 is a three-dimensional view of the decorative component in the housing assembly 100 shown in Figure 1, and Figure 17 is a three-dimensional view of the shielding cover in the housing assembly 100 shown in Figure 1.

[0123] In some embodiments, the conductive member 30 is at least one of a bracket, a mainboard 50, a decorative member, a heat sink, and a shielding cover. This configuration can better avoid the problem of interference with the camera module 20.

[0124] It is understood that the first conductive loss component 40 can be provided on each of the bracket, mainboard 50, decorative component, heat sink, and shielding cover, or all of them can be made of current-loss materials. Alternatively, the first conductive loss component 40 can be provided on one, two, or more of the bracket, mainboard 50, decorative component, heat sink, and shielding cover, or all of them can be made of current-loss materials. The bracket, mainboard 50, decorative component, heat sink, and shielding cover are all conductive, and the antenna 10 can excite standing waves on the bracket, mainboard 50, decorative component, heat sink, and shielding cover. The direction of the standing waves depends on the type, size, and shape of the conductive component 30.

[0125] When the first conduction loss component 40 is provided on the decorative member and the heat sink, since the first current generated on the decorative member and the heat sink is mainly located at their edges, the first conduction loss component 40 can be provided at the edges of the decorative member and the heat sink.

[0126] Specifically, a bracket can be understood as a structural member used to support and secure key components of an electronic device, such as the display, motherboard 50, and battery. As a crucial component of an electronic device, the bracket requires precise dimensions and shape to ensure the stability and reliability of each component within the device. Its design also needs to take into account the device's practicality and aesthetics.

[0127] The motherboard 50 is the circuit board inside an electronic device, primarily composed of electronic components such as chips, transistors, capacitors, and resistors. It typically includes a processor, memory, storage, and a graphics card. The processor is the core of the electronic device, responsible for data processing and computing. Memory provides temporary storage for running programs and data. Storage is used for long-term data storage. The graphics card is responsible for image processing and display. In addition, the motherboard 50 may also integrate components such as a power management chip, audio processing chip, and Bluetooth and Wi-Fi chips.

[0128] The decorative piece can be made of metal and is located between the rear camera module 20 and the back cover of the device housing 70. Its main function is to protect the rear camera module 20 and provide a metal decorative effect to enhance the overall aesthetics of the device.

[0129] Heat sinks are essential components for dissipating heat within electronic devices. Typically made of materials with good thermal conductivity, such as graphite, they distribute heat evenly over a larger area, effectively transferring it to the outside and maintaining the device's normal operating temperature. Heat sinks are typically used in high-heat generating areas, such as a mobile phone's CPU (Central Processing Unit) and GPU (Graphics Processing Unit), to quickly dissipate heat.

[0130] Shielding enclosures are crucial components within electronic devices, their primary function being to prevent the spread of interfering electromagnetic fields. Typically made of metal or conductive materials, they effectively block the spread of internal electromagnetic interference while also preventing external electromagnetic interference from impacting the device. Using a shielding enclosure significantly reduces the impact of electromagnetic interference on electronic device performance, ensuring device stability and reliability.

[0131] It is understood that when the dimensions of the conductive members 30 are within the electrical dimensions of the standing wave pattern in the radio frequency band of electronic equipment, the electromagnetic waves emitted by the antenna 10 easily form a standing wave pattern in these conductive members 30, generating a first standing wave. This first standing wave easily undergoes strong near-field coupling with the camera module 20. The resulting coupled noise electromagnetic field, when loaded onto the MIPI lines of the camera module 20, can cause interference issues in the camera module 20.

[0132] Please refer to Figures 1, 2 and 18. Figure 18 is a three-dimensional view of the camera module 20 in the housing assembly 100 shown in Figure 1.

[0133] On the second aspect, an embodiment of the present application provides an anti-interference structure, which includes an antenna 10 and a camera module 20. The electromagnetic waves radiated by the antenna 10 can excite a second standing wave propagating along a second direction on the camera module 20. The second standing wave includes a second electric field, and the second electric field can cause the camera module 20 to generate a second current conducted along the second direction toward one side of the second standing wave.

[0134] Among them, the interference structure includes a second conductive loss part 60, which is located on the side of the camera module 20 facing the second standing wave, and the material of the second conductive loss part 60 is current loss material; or, the material of the part of the camera module 20 facing the second standing wave is current loss material.

[0135] The anti-interference structure provided in the embodiment of the present application includes a second conductive loss part 60, and the second conductive loss part 60 is located on the side of the camera module 20 facing the second standing wave. The material of the second conductive loss part 60 is a current loss material, or the material of the part of the camera module 20 facing the second standing wave is a current loss material. Therefore, when the electromagnetic wave radiated by the antenna 10 excites a second standing wave propagating along the second direction on the camera module 20, the current loss material can convert the second current generated by the second electric field of part of the second standing wave on the camera module 20 into heat energy, thereby preventing it from forming a changing second magnetic field again, so that the intensity of the second magnetic field and the intensity of the second electric field of the second standing wave are both weakened, thereby weakening the overall intensity of the second standing wave, and then shortening the propagation distance of the second standing wave, avoiding the superposition of the second electric field / second magnetic field and the electric field / magnetic field carrying the image information signal on the MIPI line of the camera module 20, and effectively improving the interference problem caused by the second standing wave to the camera module 20.

[0136] It can be understood that the reason for the generation of the second standing wave is similar to the reason for the generation of the first standing wave, the material of the second conductive loss component 60 can be similar to the material of the first conductive loss component 40, and the second conductive loss component 60 can be pasted on the outer surface of the flexible circuit board 21 in the camera module 20.

[0137] It should be noted that the second direction may be the same as or different from the first direction. The anti-interference structure provided in the embodiment of the present application may include the first conductive loss component 40 and the second conductive loss component 60 at the same time.

[0138] Please refer to FIG. 1 , FIG. 2 and FIG. 19 . FIG. 19 is a three-dimensional view of the housing assembly 100 shown in FIG. 1 from another perspective.

[0139] In a third aspect, embodiment 1 of the present application provides a housing assembly 100 , which includes a housing 70 and an anti-interference structure as described in the first aspect or the second aspect, wherein the anti-interference structure is connected to the housing 70 .

[0140] The shell assembly 100 provided in the embodiment of the present application has an anti-interference structure including a first conductive loss part 40, and the first conductive loss part 40 is located on the side of the conductive part 30 facing the first standing wave. The material of the first conductive loss part 40 is a current loss material, or the material of the part of the conductive part 30 facing the first standing wave is a current loss material. Therefore, when the electromagnetic wave radiated by the antenna 10 excites the first standing wave propagating along the first direction on the conductive part 30, the current loss material can convert the first current generated by the first electric field of part of the first standing wave on the conductive part 30 into heat energy, thereby preventing it from forming a changing first magnetic field again, thereby weakening the intensity of the first magnetic field and the intensity of the first electric field of the first standing wave, thereby weakening the overall intensity of the first standing wave, and further shortening the propagation distance of the first standing wave, avoiding the superposition of the first electric field / first magnetic field and the electric field / magnetic field carrying the image information signal on the MIPI line of the camera module 20, and effectively improving the interference problem caused by the first standing wave on the camera module 20.

[0141] The shell assembly 100 provided in the embodiment of the present application has an anti-interference structure including a second conductive loss part 60, and the second conductive loss part 60 is located on the side of the camera module 20 facing the second standing wave. The material of the second conductive loss part 60 is a current loss material, or the material of the part of the camera module 20 facing the second standing wave is a current loss material. Therefore, when the electromagnetic wave radiated by the antenna 10 excites a second standing wave propagating along the second direction on the camera module 20, the current loss material can convert the second current generated by the second electric field of part of the second standing wave on the camera module 20 into heat energy, thereby preventing it from forming a changing second magnetic field again, so that the intensity of the second magnetic field and the intensity of the second electric field of the second standing wave are both weakened, thereby weakening the overall intensity of the second standing wave, and further shortening the propagation distance of the second standing wave, avoiding the superposition of the second electric field / second magnetic field and the electric field / magnetic field carrying the image information signal on the MIPI line of the camera module 20, and effectively improving the interference problem caused by the second standing wave to the camera module 20.

[0142] It can be understood that the anti-interference structure can be completely set inside the shell 70; or, the shell 70 includes a middle frame 71, part of the camera module 20 is snapped into the shell 70, the conductive part 30 can be bonded to the main board 50 inside the shell 70, the first conductive loss part 40 is bonded to the conductive part 30, the second conductive loss part 60 is bonded to the camera module 20, and the antenna 10 is integrally formed with the middle frame 71 of the shell 70.

[0143] Please continue to refer to Figures 1, 2 and 19. In this embodiment, the electromagnetic waves radiated by the antenna 10 can excite a third standing wave propagating along a third direction on the shell 70. The third standing wave includes a third electric field, and the third electric field can cause the shell 70 to generate a third current conducted along the third direction toward the side of the third standing wave.

[0144] Among them, the anti-interference structure includes a third conduction loss component 72, which is located on the side of the shell 70 facing the third standing wave, and the material of the third conduction loss component 72 is current loss material; or, the material of the side of the shell 70 facing the third standing wave is current loss material.

[0145] By adopting the above-mentioned scheme, when the electromagnetic wave radiated by the antenna 10 excites a third standing wave propagating along the third direction on the shell 70, the current loss material can convert part of the third electric field of the third standing wave into heat energy on the shell 70 to generate a third current, thereby preventing it from forming a changing third magnetic field again, thereby weakening the intensity of the third magnetic field and the intensity of the third electric field of the third standing wave, thereby weakening the overall intensity of the third standing wave, and shortening the propagation distance of the third standing wave, avoiding the superposition of the third electric field / third magnetic field and the electric field / magnetic field carrying the image information signal on the MIPI line of the camera module 20, and effectively improving the interference problem caused by the third standing wave to the camera module 20.

[0146] It can be understood that the cause of the third standing wave is similar to that of the first standing wave, the material of the third conductive loss component 72 can be similar to that of the first conductive loss component 40, and the third conductive loss component 72 can be pasted on the middle frame 71 of the shell 70.

[0147] It should be noted that the third direction may be the same as or different from the first direction. The housing assembly 100 provided in the embodiment of the present application may include a first conduction loss component 40 , a second conduction loss component 60 and a third conduction loss component 72 .

[0148] Please refer to FIG. 1 , FIG. 2 and FIG. 20 . FIG. 20 is a perspective exploded view of the housing assembly 100 shown in FIG. 1 from another perspective.

[0149] In a fourth aspect, a first embodiment of the present application provides an electronic device, which includes the housing assembly 100 according to the third aspect.

[0150] The electronic device provided in the embodiment of the present application has an anti-interference structure including a first conductive loss part 40, and the first conductive loss part 40 is located on the side of the conductive part 30 facing the first standing wave. The material of the first conductive loss part 40 is a current loss material, or the material of the part of the conductive part 30 facing the first standing wave is a current loss material. Therefore, when the electromagnetic wave radiated by the antenna 10 excites the first standing wave propagating along the first direction on the conductive part 30, the current loss material can convert the first current generated by the first electric field of part of the first standing wave on the conductive part 30 into heat energy, thereby preventing it from forming a changing first magnetic field again, thereby weakening the intensity of the first magnetic field and the intensity of the first electric field of the first standing wave, thereby weakening the overall intensity of the first standing wave, and further shortening the propagation distance of the first standing wave, avoiding the superposition of the first electric field / first magnetic field and the electric field / magnetic field carrying the image information signal on the MIPI line of the camera module 20, and effectively improving the interference problem caused by the first standing wave to the camera module 20.

[0151] The electronic device provided in the embodiment of the present application has an anti-interference structure including a second conductive loss part 60, and the second conductive loss part 60 is located on the side of the camera module 20 facing the second standing wave. The material of the second conductive loss part 60 is a current loss material, or the material of the part of the camera module 20 facing the second standing wave is a current loss material. Therefore, when the electromagnetic wave radiated by the antenna 10 excites a second standing wave propagating along the second direction on the camera module 20, the current loss material can convert the second current generated by the second electric field of part of the second standing wave on the camera module 20 into heat energy, thereby preventing it from forming a changing second magnetic field again, so that the intensity of the second magnetic field and the intensity of the second electric field of the second standing wave are both weakened, thereby weakening the overall intensity of the second standing wave, and then shortening the propagation distance of the second standing wave, avoiding the superposition of the second electric field / second magnetic field and the electric field / magnetic field carrying the image information signal on the MIPI line of the camera module 20, and effectively improving the interference problem caused by the second standing wave to the camera module 20.

[0152] It can be understood that the anti-interference structure of the shell assembly 100 may include a third conductive loss part 72. When the electromagnetic wave radiated by the antenna 10 excites a third standing wave propagating along a third direction on the shell 70, the current loss material can convert part of the third current generated by the third electric field of the third standing wave on the shell 70 into heat energy, thereby preventing it from forming a changing third magnetic field again, thereby weakening the intensity of the third magnetic field and the intensity of the third electric field of the third standing wave, thereby weakening the overall intensity of the third standing wave, and further shortening the propagation distance of the third standing wave, effectively improving the interference problem caused by the third standing wave on the camera module 20.

[0153] It should be noted that the electronic device provided in the embodiment of the present application may also include a battery, a microphone, and an earpiece assembly, etc., which are arranged in the housing 70.

[0154] Please refer to Figures 1, 2 and 20. In this embodiment, the electronic device includes a screen module 80, and the antenna 10 can excite a fourth standing wave propagating along a fourth direction on the screen module 80.

[0155] Among them, the anti-interference structure includes a fourth conduction loss component 82, which is located on the side of the screen module 80 facing the fourth standing wave, and the material of the fourth conduction loss component 82 is current loss material; or, the material of the part of the screen module 80 facing the fourth standing wave is current loss material.

[0156] By adopting the above-mentioned scheme, when the antenna 10 excites the fourth standing wave propagating along the fourth direction on the screen module 80, the current loss material can convert part of the fourth current generated by the fourth electric field of the fourth standing wave on the screen module 80 into heat energy, thereby preventing it from forming a changing fourth magnetic field again, thereby weakening the intensity of the fourth magnetic field and the intensity of the fourth electric field of the fourth standing wave, thereby weakening the overall intensity of the fourth standing wave, and shortening the propagation distance of the fourth standing wave, avoiding the superposition of the fourth electric field / fourth magnetic field and the electric field / magnetic field carrying the image information signal on the MIPI line of the camera module 20, and effectively improving the interference problem caused by the fourth standing wave on the camera module 20.

[0157] Specifically, the screen module 80 includes a screen 81 , and the fourth conductive loss component 82 is adhered to the back of the screen 81 .

[0158] It is understood that the cause of the fourth standing wave is similar to that of the first standing wave, and the material of the fourth conductive loss member 82 can be similar to that of the first conductive loss member 40. The screen module 80 can include a screen 81, and the fourth conductive loss member 82 can be attached to the screen 81.
