Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to an anti-interference structure, a housing assembly and an electronic equipment. Background Art

[0002] In order to realize the communication function, some electronic devices often need to set up various antennas for signal transmission to transmit and receive signals. In order to meet the requirements of communication in multiple frequency bands, there are more and more types of antennas in electronic devices such as mobile phones, tablets and smart watches. In order to meet the needs of use, other functional modules are also integrated in electronic devices, such as camera modules.

[0003] During the use of traditional electronic devices, since the antenna and camera module are both located inside the electronic device, the antenna is likely to cause interference to the camera module when transmitting radio frequency signals, causing the camera module to experience interference phenomena such as screen distortion, freeze and freezing, resulting in a poor user experience. Summary of the invention

[0069] Embodiments of the present application are described in detail below, and examples of the embodiments 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.

[0071] The terms "first", "second", "third", "fourth", etc. are only used to distinguish descriptions and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. For example, the first push part and the second push part are only used to distinguish different push parts, and their order is not limited. The first push part can also be named as the second push part, and the second push part can also be named as the first push part without departing from the scope of the various described embodiments. And the terms "first", "second", "third", "fourth", etc. do not limit the indicated features to be different.

[0072] In this application, unless otherwise clearly specified and limited, the terms "connected", "connection" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0073] In this application, "and / or" is only a description of the association relationship of associated objects, indicating that there can be three relationships; for example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0074] It should be noted that, in this application, words such as "in one embodiment", "exemplarily", "for example", etc. are used to indicate examples, illustrations or descriptions. Any embodiment or design described in this application as "in one embodiment", "exemplarily", "for example" should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "in one embodiment", "exemplarily", "for example", etc. is intended to present related concepts in a specific way.

[0075] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0076] During the use of traditional electronic devices, since the antenna and camera module are both located inside the electronic device, the camera module is easily interfered when the antenna transmits signals, causing the camera module to experience interference phenomena such as screen noise, freeze and freezing, resulting in a poor user experience.

[0077] Electronic devices are also equipped with conductive parts such as brackets, motherboards, decorative parts (Deco), heat sinks and shielding covers. When the antenna transmits a radio frequency signal, the wavelength of the electromagnetic wave radiated by it corresponds to the size of the conductive part. For example, when the size of the conductive part is equal to or close to 1 / 4 or 1 / 2 of the wavelength of the electromagnetic wave, the conductive part couples the electromagnetic wave radiated by the antenna, and standing waves are generated in these conductive parts.

[0078] 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 in turn 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.

[0079] There are strong electric / magnetic points in the propagation direction of the standing wave, and the conductive parts have positions corresponding to the strong electric / magnetic points, which leads to very strong near-field coupling between the conductive parts at the positions of the corresponding strong electric / magnetic points and the camera module. The electric / magnetic field carrying the image information signal on the MIPI line of the camera module and the electric / magnetic field of the standing wave will be superimposed on each other to form a superimposed signal. When the superimposed signal is transmitted to the SoC (System on Chip) for demodulation, the SoC cannot demodulate the superimposed signal, which will cause interference problems in the camera module.

[0080] 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.

[0081] In view of this, the 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.

[0082] The electronic device provided in the embodiment of the present application may 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) device, a virtual reality (VR) device, a vehicle-mounted device, or other electronic device with an antenna and a camera module, but is not limited thereto. In the embodiment of the present application, the electronic device is a mobile phone as an example for description.

[0083] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 1 This is a three-dimensional assembly diagram of the housing assembly 100 provided in an embodiment of the present application. Figure 2 for Figure 1 The exploded perspective view of the housing assembly 100 is shown. Figure 3 for Figure 1 A perspective view of the bracket in the body assembly shown, Figure 4 for Figure 1 The model diagram of the anti-interference structure in the housing assembly 100 is shown, Figure 5 for Figure 4 A schematic diagram of the relative positions of the bracket, the first conduction loss component 40 and the main board 50 in the anti-interference structure is shown.

[0084] In a first aspect, a first embodiment of the present application provides an anti-interference structure for use in an electronic device. The electronic device further includes a housing 70 , and the housing 70 is connected to the anti-interference structure.

[0085] The anti-interference structure includes an antenna 10, a camera module 20 and a conductive member 30. The conductive member 30 is located in a 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 a first direction toward one side of the first standing wave, wherein:

[0086] The anti-interference structure includes a first conductive loss component 40 . The first conductive loss component 40 is located on a side of the conductive component 30 facing the first standing wave. The first conductive loss component 40 is made of a current loss material.

[0087] Alternatively, the portion of the conductive member 30 facing the first standing wave is made of a current loss material.

[0088] It should be noted that the antenna 10 is a component on an electronic device for receiving and sending radio frequency signals, and can radiate electromagnetic waves. For example, the antenna 10 can be a 5G WIFI antenna or a 5G N78 antenna, etc. In addition, the antenna 10 may have multiple frequency bands. The antenna 10 sends wireless radio frequency signals, and the antenna 10 radiates electromagnetic waves.

[0089] As an example, the antenna 10 can be integrated into the housing 70 of the electronic device. Specifically, the antenna 10 can be located in the middle frame 71 of the housing 70, which can not only better protect the antenna 10, but also avoid interference from other components, thereby improving the quality of signal reception. In addition, the middle frame 71 can also provide stable support and fixation for the antenna 10. Integrating the antenna 10 in the middle frame 71 of the housing 70 can improve the overall aesthetics and integrity of the mobile phone.

[0090] The camera module 20 may include a camera for lighting and imaging. The camera module 20 may be further divided into a front camera module 20 and a rear camera module 20. Multiple of these modules may be provided.

[0091] In addition, the conductive member 30 may be made of metal or other conductive materials. Specifically, the conductive member 30 may include a bracket, a mainboard 50, a decorative member (Deco), a heat sink, and a shielding cover of the electronic device. In this embodiment, the conductive member 30 is a bracket.

[0092] 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 in the figure), and the camera module 20 defines a second plane (not shown in the figure). Both planes are perpendicular to the first direction. The conductive member 30 is located in the space between the first plane and the second plane, not only on the line between the antenna 10 and the camera module 20.

[0093] In this embodiment, the anti-interference structure includes a first conductive lossy member 40 , which is located on a side of the conductive member 30 facing the first standing wave. Specifically, the first conductive lossy member 40 may be located between the conductive member 30 and the main board 50 .

[0094] The first conductive loss component 40 and the conductive component 30 can be connected by bonding, welding, clamping or threading. Alternatively, the current loss material is directly deposited on the conductive component 30, so that the current loss material forms the first conductive loss component 40. The current loss material refers to a material that can consume current and has the ability to absorb current, specifically, the current will be absorbed in the current loss material, and the energy of the current will be converted in the current loss material to form other forms of energy without generating a magnetic field.

[0095] For example, the current loss material may be a material with low electrical conductivity that is able to convert electrical current into heat. Electrical conductivity is a measure of the ability of a material to carry electrical current. It is defined by Ohm's law as the ratio of current density to electric field strength, and electrical conductivity is the reciprocal of resistivity. The SI unit of electrical conductivity is Siemens / meter (S / m).

[0096] 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 surface of the conductive component 30, the first conductive loss component 40 may cover the conductive component 30.

[0097] For example, see 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.

[0098] In other embodiments, the conductive element 30 is made of a current loss material on the side facing the first standing wave. With this arrangement, part of the current can be directly converted by the conductive element 30 .

[0099] 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 all the conductive elements 30 is a current loss material.

[0100] It should be noted that the current loss material can be one of an alloy material, a semiconductor material and a clay material, so as to facilitate the use of the current loss material to make the first conduction loss part 40. Among them, the alloy material can be specifically nickel-chromium, chromium-nickel-iron, manganese-copper or constantan, etc.; the semiconductor material can be specifically silicon or germanium, etc., and the clay material can be specifically carbon clay, etc. The current loss material can absorb the current energy and convert it into heat energy.

[0101] 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 member 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 member 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 of the first standing wave on the camera module 20.

[0102] It can be understood that, on the whole, 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 of the first standing wave on the camera module 20.

[0103] 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 component 40, and the first conductive loss component 40 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 a current loss material, or the material of the part of the conductive component 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 component 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 component 30 into heat energy, thereby preventing it from forming a changing first magnetic field again, so that the intensity of the first magnetic field and the intensity of the first electric field of the first standing wave can be weakened, 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.

[0104] 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 suitable for decoupling problems in any frequency band and does not have the 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.

[0105] Please refer to Figure 2 , Figure 3 and Figure 4 In the first embodiment, within the temperature range of -50°C to 200°C, the conductivity of the current loss material along the first direction is less than or equal to 8000 S / m.

[0106] By adopting the above scheme, the current loss material can convert a larger part of the first current into heat energy, thereby weakening the intensity of the first magnetic field and 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.

[0107] It can be understood that the temperature range of -50℃ to 200℃ is the general operating environment temperature range of electronic equipment. Whether the conductivity has directionality depends on the specific material and situation. For general materials, the conductivity is isotropic, that is, the conductivity measured in different directions is the same. Therefore, for these materials, the conductivity has no directionality. At this time, it is sufficient to ensure that the conductivity of the current loss material in all directions is less than or equal to 8000S / m.

[0108] 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.

[0109] 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 first conductive loss component 40 is made of 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.

[0110] By adopting the above solution, the relative positions of the first conductive loss component 40 and the conductive component 30 can be conveniently set, and a larger portion of the first current can be converted into heat energy through the first conductive loss component 40 .

[0111] In this embodiment, the first conductive loss component 40 is disposed on the outer surface of the conductive component 30. This arrangement facilitates the location of the first conductive loss component 40 and enables a larger portion of the first current to be converted into heat energy through the first conductive loss component 40.

[0112] Please refer to Figure 6 and Figure 7 , Figure 6 Schematic diagram of simulation of antenna 10-MIPI (Mobile Industry Processor Interface) isolation in a traditional housing assembly 100. Figure 7 It is a simulation schematic diagram of the alternating distribution diagram of the electric field and the magnetic field on the conductive member 30 in the traditional housing assembly 100 .

[0113] from Figure 6 It can be seen that 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.

[0114] from Figure 7 It can be seen that 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. Compared with the non-standing wave mode state, the strong electric field / magnetic field of the standing wave mode will greatly enhance the near-field coupling between the bracket and the antenna 10.

[0115] Please refer to Figure 8 and Fig. 9 , Figure 8 A schematic diagram of a simulation of the electric field strength of the conductive member 30 in the housing assembly 100 provided in the first embodiment of the present application in the first conductive loss member 40 when the conductivity is 1000 S / m and 3000 S / m respectively and the conductive member 30 in the conventional housing assembly 100 under the standing wave mode, Fig. 9 for Figure 1 The isolation degree comparison diagram of the conductive member 30 in the housing assembly 100 and the anti-interference structure in the traditional housing assembly 100 is shown.

[0116] from Figure 8 It can be seen that 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 of the first standing wave on the camera module 20.

[0117] from Fig. 9 It can be seen from the figure that as the conductivity of the first conductive loss element 40 decreases, the value of the isolation is continuously improved.

[0118] Please refer to Fig.10 and Fig.11 , Fig.10 Schematic diagram of the relative positions of the bracket, the first conduction loss component 40 and the main board 50 in the anti-interference structure provided in the second embodiment of the present application. Fig.11 for Fig.10 The isolation degree comparison diagram of the conductive member 30 in the housing assembly 100 and the anti-interference structure in the traditional housing assembly 100 is shown.

[0119] Different from the first embodiment, in this embodiment, the first conduction loss component 40 is located between the bracket and the main board 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 main board 50 .

[0120] Fig.11 The middle curves 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 component 40 is ordinary metal, the antenna 10-MIPI isolation curve when the conductivity of the first conductive loss component 40 is 3000S / m, and the antenna 10-MIPI isolation curve when the conductivity of the first conductive loss component 40 is 1000S / m.

[0121] from Fig.11 It can be seen that the first conductive lossy component 40 is located between the bracket and the main board 50, and the solution in which there are gaps between the first conductive lossy component 40 and the bracket, and between the first conductive lossy component 40 and the main board 50 also has a certain effect on improving the isolation. And as the conductivity of the first conductive lossy component 40 decreases, the effect of improving the isolation is more obvious.

[0122] In this embodiment, the first conductive loss component 40 is adhered to the bracket, so there is a gap between the two.

[0123] Please refer to Fig.12 and Fig.13 , Fig.12 Schematic diagram of the relative positions of the bracket and the mainboard 50 in the anti-interference structure provided in the third embodiment of the present application. Fig.13 for Fig.12 The isolation degree comparison diagram of the conductive member 30 in the housing assembly 100 and the anti-interference structure in the traditional housing assembly 100 is shown.

[0124] Different from the first embodiment, in this embodiment, the material of the bracket is a current loss material.

[0125] Fig.13 The middle curves are, from top to bottom, the isolation curve in the traditional housing assembly 100, the antenna 10-MIPI isolation curve when the electrical conductivity of the bracket is 3000 S / m, and the antenna 10-MIPI isolation curve when the electrical conductivity of the bracket is 1000 S / m.

[0126] from Fig.11 It can be seen that setting the material of the entire bracket as a current loss material also has a certain effect on improving the isolation. And as the conductivity of the bracket decreases, the improvement effect on the isolation is more obvious.

[0127] Please refer to Fig.14 , Fig.14 It is a schematic diagram of the relative positions of the bracket, the first conduction loss component 40 and the main board 50 in the anti-interference structure provided in the fourth embodiment of the present application.

[0128] Different from the first embodiment, in this embodiment, the first conduction loss component 40 is located on the side of the conductive component 30 facing the first standing wave. Specifically, the first conduction loss component 40 may be located on the side of the conductive component 30 facing away from the main board 50 .

[0129] By adopting the above scheme, when the electromagnetic wave radiated by the antenna 10 excites a first standing wave propagating along a first direction on the conductive member 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 member 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 of the first standing wave on the camera module 20.

[0130] Please refer to Fig.15 , Fig.15 It is a schematic diagram of the relative positions of the bracket, the first conduction loss component 40 and the main board 50 in the anti-interference structure provided in the fifth embodiment of the present application.

[0131] Different from the fourth embodiment, in this embodiment, the first conduction loss component 40 is located on the side of the conductive component 30 facing the first standing wave. Specifically, the first conduction loss component 40 can be located on the side of the conductive component 30 away from the main board 50, and there can be a gap between the first conduction loss component 40 and the conductive component 30.

[0132] By adopting the above scheme, when the electromagnetic wave radiated by the antenna 10 excites a first standing wave propagating along a first direction on the conductive member 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 member 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 of the first standing wave on the camera module 20.

[0133] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig.16 and Fig.17 , Fig.16 for Figure 1 A perspective view of a decorative element in the housing assembly 100 is shown. Fig.17 for Figure 1 A perspective view of a shield cover in the housing assembly 100 is shown.

[0134] 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 arrangement can better avoid the problem of interference to the camera module 20.

[0135] It is understandable that the first conductive loss component 40 can be set on the bracket, the main board 50, the decorative component, the heat sink and the shielding cover, or the material can be set to current loss material; or the first conductive loss component 40 can be set on one, two or more of the bracket, the main board 50, the decorative component, the heat sink and the shielding cover, or the material can be set to current loss material. The bracket, the main board 50, the decorative component, the heat sink and the shielding cover are all conductive, and the antenna 10 can excite standing waves on the bracket, the main board 50, the decorative component, the heat sink and the shielding cover, but the direction of the standing wave is related to the type, size and shape of the conductive component 30.

[0136] When the first conduction loss component 40 is disposed on the decorative component and the heat sink, since the first current generated on the decorative component and the heat sink is mainly located at the edges thereof, the first conduction loss component 40 can be disposed at the edges of the decorative component and the heat sink.

[0137] Specifically, the bracket can be understood as a structural member used to support and fix the main components of the electronic device, such as the display screen, the mainboard 50 and the battery. As an important component of the electronic device, the bracket needs to have precise size and shape to ensure the stability and reliability of each component in the device. Its design also needs to take into account the practicality and appearance of the device.

[0138] The motherboard 50 is a circuit board inside an electronic device, which is mainly composed of electronic components such as chips, transistors, capacitors, resistors, etc. It usually includes a processor, memory, storage, graphics card, etc. The processor is the core of the electronic device and is responsible for data processing and calculation. The memory provides temporary storage space for storing running programs and data. The storage is used for long-term data storage. The graphics card is responsible for image processing and display. In addition, the motherboard 50 can also integrate components such as power management chips, audio processing chips, Bluetooth and WIFI chips.

[0139] 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.

[0140] Heat sinks are important components used to dissipate heat inside electronic devices. They are usually made of materials with good thermal conductivity, such as graphite, and can evenly distribute the heat inside the device to a larger area, thereby effectively transferring the heat to the outside and maintaining the normal operating temperature of the electronic device. Heat sinks are generally used in high-heat areas such as the CPU (Central Processing Unit) and GPU (Graphics Processing Unit) of mobile phones to help these areas dissipate heat quickly.

[0141] The shielding cover is an important component inside electronic equipment. Its main function is to prevent the interference electromagnetic field from spreading outward. It is usually made of metal or conductive materials, which can effectively block the electromagnetic interference generated inside from spreading outward, and also prevent the external electromagnetic interference from affecting the internal equipment. By using a shielding cover, the impact of electromagnetic interference on the performance of electronic equipment can be greatly reduced, ensuring the stability and reliability of the equipment.

[0142] It is understandable that when the size of the conductive member 30 is within the electrical size range of the standing wave mode in the radio frequency band of the electronic device, the electromagnetic waves emitted by the antenna 10 are very likely to form a standing wave mode in these conductive members 30, generating a first standing wave, and a very strong near-field coupling is very likely to occur between the first standing wave and the camera module 20. The related coupled noise electromagnetic field is loaded on the MIPI line of the camera module 20, which will cause interference problems in the camera module 20.

[0143] Please refer to Figure 1 , Figure 2 and Fig.18 , Fig.18 for Figure 1 A stereoscopic view of the camera module 20 in the housing assembly 100 is shown.

[0144] On the second aspect, an embodiment of the present application provides an anti-interference structure, which includes an antenna 10, a camera module 20 and a second magnetic loss part. 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.

[0145] Among them, the interference structure includes a second conduction loss component 60, which is located on the side of the camera module 20 facing the second standing wave, and the material of the second conduction loss component 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.

[0146] The anti-interference structure provided in the embodiment of the present application includes a second conductive loss component 60, and the second conductive loss component 60 is located on the side of the camera module 20 facing the second standing wave. The material of the second conductive loss component 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 the 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, thereby 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 of the second standing wave on the camera module 20.

[0147] 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.

[0148] 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.

[0149] Please refer to Figure 1 , Figure 2 and Fig.19 , Fig.19 for Figure 1 A perspective view of the housing assembly 100 from another perspective is shown.

[0150] In a third aspect, the first embodiment of the present application provides a housing assembly 100 , which includes a housing 70 and an anti-interference structure as in the first aspect or the second aspect, wherein the anti-interference structure is connected to the housing 70 .

[0151] 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, thereby 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 of the first standing wave on the camera module 20.

[0152] The shell assembly 100 provided in the embodiment of the present application has an anti-interference structure including a second conductive loss component 60, and the second conductive loss component 60 is located on the side of the camera module 20 facing the second standing wave. The material of the second conductive loss component 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 the 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, thereby 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 of the second standing wave on the camera module 20.

[0153] 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.

[0154] Please continue to refer to Figure 1 , Figure 2 and Fig.19In 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.

[0155] 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.

[0156] By adopting the above scheme, when the electromagnetic wave radiated by the antenna 10 excites the third standing wave propagating along the third direction on the shell 70, the current loss material can convert the third electric field of part of the third standing wave into heat energy on the shell 70 to avoid 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, 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 of the third standing wave on the camera module 20.

[0157] It is understandable that the cause of the third standing wave is similar to that of the first standing wave, the material of the third conduction loss component 72 can be similar to that of the first conduction loss component 40 , and the third conduction loss component 72 can be pasted on the middle frame 71 of the shell 70 .

[0158] 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 at the same time.

[0159] Please refer to Figure 1 , Figure 2 and Fig. 20 , Fig. 20 for Figure 1 The housing assembly 100 is shown in a perspective exploded view from another perspective.

[0160] In a fourth aspect, a first embodiment of the present application provides an electronic device, and the electronic device includes a housing assembly 100 as described in the third aspect.

[0161] The electronic device provided in the embodiment of the present application has an anti-interference structure including a first conductive loss component 40, and the first conductive loss component 40 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 a current loss material, or the material of the part of the conductive component 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 component 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 component 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, thereby 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 of the first standing wave on the camera module 20.

The material of the second conductive loss component 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 the 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, thereby 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 of the second standing wave on the camera module 20.

[0163] 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 of the third standing wave on the camera module 20.

[0164] 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.

[0166] 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.

[0167] By adopting the above 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 fourth electric field of the fourth standing wave, thereby weakening the overall intensity of the fourth standing wave, thereby 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 of the fourth standing wave on the camera module 20.

[0168] Specifically, the screen module 80 includes a screen 81 , and the fourth conductive loss component 82 is adhered to the back side of the screen 81 .

[0169] It is understandable that the cause of the fourth standing wave is similar to that of the first standing wave, and the material of the fourth conduction loss component 82 can be similar to that of the first conduction loss component 40. The screen module 80 can include a screen 81, and the fourth conduction loss component 82 can be attached to the screen 81.
