[0001] This application relates to the field of electromagnetic radiation technology, specifically to a shielding device, method, electronic device, and storage medium. Background Technology

[0002] In related technologies, signal shielding of devices (such as circuits, components, and devices) is usually achieved by using a metal casing. This limits the application scenarios of the devices to be shielded. Due to the size of the device being shielded, if the size is too large, a larger enclosure is required for shielding.

[0003] Currently, electromagnetic shielding is mainly achieved by adding a metal shell around the device to be shielded. However, how to shield and protect existing products or products that cannot be protected by a metal shell due to space requirements has become an important issue. Summary of the Invention

[0015] This application provides a shielding device, method, electronic device, and storage medium for shielding electromagnetic interference from a device to be shielded. The device includes a signal transmitting board and a signal receiving board. High-frequency electromagnetic signals are transmitted through the signal transmitting and receiving boards to generate a signal shielding area, thus shielding the device from electromagnetic interference from the external environment. The signal transmitting and receiving boards can be positioned as needed to accommodate devices with different spatial requirements. The shielding of electromagnetic interference using high-frequency electromagnetic signals provides reliable protection for the device.

[0016] It should be understood that the content described in this section is not intended to identify key or important features of the embodiments of this application, nor is it intended to limit the scope of this application. Other features of this application will become readily apparent from the following description. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0023] In related technologies, metal housings are used to achieve signal shielding. However, this is affected by the size of the device being shielded. If the size is too large, a larger shielding housing is required. Although existing technologies have improved the shielding housing, the question of how to provide EMI protection for already manufactured products or products that cannot be protected by metal housings due to space requirements remains to be addressed.

[0024] To address the aforementioned problems and considering the issues existing in the prior art, the applicant has proposed a shielding device, method, electronic device, and storage medium according to embodiments of this application. These devices generate a signal shielding area by transmitting high-frequency electromagnetic signals using a signal transmitting board and a signal receiving board, thereby shielding the device from electromagnetic interference from the external environment. This provides bidirectional EMI shielding for circuits, components, and devices with space requirements or without metal casing protection. The shielding device will be described in detail in subsequent embodiments.

[0025] The shielding method in this embodiment can be applied to the device to be shielded, wherein the device to be shielded may include, but is not limited to, irregular devices, components, circuits, etc.

[0026] Furthermore, after the device to be shielded is shielded from electromagnetic interference by a conventional housing, it can also be used in this shielding device. That is, the shielded device can also be shielded from electromagnetic interference again by the signal transmitting board 1 and the signal receiving board 2 of this application.

[0027] Please see Figure 1 , Figure 1 This is a schematic diagram of a shielding device provided in an embodiment of this application.

[0028] The shielding device provided in this application embodiment includes:

[0029] Signal transmitter board 1 is used to transmit high-frequency electromagnetic signals.

[0030] Signal receiving board 2 is used to receive high-frequency electromagnetic signals.

[0031] The signal transmitting board 1 and the signal receiving board 2 generate a signal shielding area by transmitting high-frequency electromagnetic signals, so as to shield the devices to be shielded from electromagnetic interference within the signal shielding area.

[0032] exist Figure 1 In the process, after the high-frequency transmitting board and the high-frequency receiving board establish inter-board communication, the high-frequency electromagnetic shielding network is gradually established as the signal stabilizes. The transmitting board continuously transmits electromagnetic signals to the receiving board, forming a stable high-frequency electromagnetic shielding network, which can achieve bidirectional EMI shielding without metal isolation materials.

[0033] In the aforementioned shielding device, a signal shielding area is generated by transmitting high-frequency electromagnetic signals through the signal transmitting board 1 and the signal receiving board 2 to shield the electromagnetic interference from the external environment of the device to be shielded. The signal transmitting board 1 and the signal receiving board 2 can be positioned as needed to meet the requirements of different space requirements of the devices to be shielded. This saves the shielding metal plate and the space required for the metal plate, thereby reducing the weight of the product itself, reducing assembly time and material preparation time, and realizing bidirectional EMI shielding without metal isolation materials.

[0034] It should be noted that this application is applicable to industrial environments and electrical usage scenarios where there are a large number of stray magnetic fields, EMI magnetic field environments, and alternating magnetic fields. Alternating magnetic fields can have some impact on electronic components that use metal casings to shield against EMI. Alternating magnetic fields can induce currents inside the metal casings, and these induced currents generate induced magnetic fields, which can have some impact on electronic components. However, since the casings are generally grounded, the impact is relatively small, but it still affects the electronic components. For sensitive electronic components, such as sound wave generators, nuclear magnetic resonance generators, and information transmission lines, and for electronic components and equipment with high EMI requirements, the shielding method in this invention can be used to completely avoid the problems existing in the prior art.

[0035] In some embodiments, the shielding device further includes:

[0036] The detection device is used to detect high-frequency electromagnetic signals and electromagnetic interference signals in the environment where the device to be shielded is located. The control device is used to control and adjust the strength of the high-frequency electromagnetic signals according to the electromagnetic interference signals or user instructions. The signal transmission device is used to establish signal shielding areas of different sizes according to the strength of the high-frequency electromagnetic signals.

[0037] The aforementioned detection device can be a high-frequency electromagnetic wave identification device installed on the signal transmitting board 1 or the signal receiving board 2. It is a small waveform detection instrument used to identify the high-frequency electromagnetic waves emitted by the signal transmitting board 1. Furthermore, it can detect the main interfering electromagnetic waves in the working environment of the device to be shielded. By detecting the signal transmitting board 1 and the signal receiving board 2, it obtains the signal communication status between the boards. The control device can interact with some external devices to complete control, such as mobile phones, computers, and other electronic devices. It can control the shielding device to complete external interactions, high-frequency electromagnetic signal adjustment, and other functions. The control device can also be installed on the signal transmitting board 1 or the signal receiving board 2, or externally placed in other locations as needed. The signal transmission device is used for shielding the signal transmission part. It is mainly responsible for establishing the high-frequency electromagnetic shielding network, i.e., the signal shielding area. For example, the signal transmission device can construct a stable electromagnetic shielding network based on the stability or strength of the current high-frequency electromagnetic signal. Furthermore, the signal transmission device can also be positioned as described above according to usage requirements.

[0038] In practical applications, this application can shield corresponding devices by selecting the appropriate operating conditions and formulating shielding electromagnetic wave properties and protocols, thereby achieving unobstructed EMI protection and providing reliable EMI protection for circuits, components, and devices with space requirements or without metal casing protection.

[0039] By detecting and controlling the strength of high-frequency electromagnetic signals, a stable and adjustable signal shielding area can be constructed to better shield the devices to be shielded according to the usage requirements, thereby achieving a better shielding effect.

[0040] In some embodiments, the signal transmitting board 1 and the signal receiving board 2 are arranged opposite to each other.

[0041] By setting the signal transmitting board 1 and the signal receiving board 2 opposite each other in appropriate positions, the generated signal shielding area can be more stable and the power consumption required for shielding can be reduced.

[0042] Of course, the positions of the signal transmitting board 1 and the signal receiving board 2 can be adjusted according to specific usage requirements, and this application does not specify them individually.

[0043] In order to reduce power loss from shielding.

[0044] In some embodiments, a copper column is provided between the signal transmitting board 1 and the signal receiving board 2, and a high-voltage frequency converter is connected to the non-end area of ​​the copper column. The two ends of the copper column are respectively connected to the signal transmitting board 1 and the signal receiving board 2.

[0045] In this embodiment, a high-frequency alternating electric field is generated by supplying AC power to the copper column through a high-voltage frequency converter to shield external interference. This solves the problem of high power loss between the signal transmitting board 1 and the signal receiving board 2. Instead, the power supply to the copper column is used to shield external interference signals and reduce power consumption.

[0046] In some embodiments, the shielding device further includes a signal converter, which is disposed between the signal transmitting board 1 and the signal receiving board 2, for correcting the high-frequency electromagnetic signal transmitted by the signal transmitting board 1 and transmitting the corrected high-frequency electromagnetic signal to the signal receiving board 2.

[0047] In this embodiment, a signal converter can be provided in the middle part around the double plates, which can make the high-frequency electromagnetic shielding mesh form a regular rhombus shape to further stabilize the signal shielding area. Similarly, after correcting the high-frequency electromagnetic signal, the shielding device can further improve its shielding capability against external interference and change the shape of the shielding space to meet the EMI shielding needs of different process equipment.

[0048] In some embodiments, the detection device is also used to detect interference signals generated by the device to be shielded.

[0049] In this embodiment of the application, the device to be shielded, which is located in the signal shielding area, also experiences electromagnetic interference during operation. The electromagnetic interference inside the device is detected by a detection device, and then reasonable adjustments are made to ensure a better bidirectional EMI shielding function.

[0050] In some possible implementations, the detection device is also used to detect interference signals generated by the device to be shielded.

[0051] In this embodiment of the application, the device to be shielded, which is located in the signal shielding area, also experiences electromagnetic interference during operation. The electromagnetic interference inside the device is detected by a detection device, and then reasonable adjustments are made to ensure a better bidirectional EMI shielding function.

[0052] In practical applications, considering the need to reduce the energy consumption required to construct a strong signal shielding area, the device to be shielded, which is shielded by metal, can be shielded again by a shielding device to achieve better shielding while reducing power consumption.

[0053] In some possible implementations, the shielding device further includes: a base plate on which the device to be shielded is disposed, and a shielding cover plate for sealing and covering the device to be shielded on the base plate.

[0054] In this embodiment, the device to be shielded is sealed by the base plate and the shielding cover plate to shield against external electromagnetic interference. In actual use, considering that the sealed box will be filled with interfering equipment, whether electromagnetic waves will leak in or out through gaps and holes depends on the wavelength of the electromagnetic waves. When the wavelength is much larger than the diameter of the hole or gap, electromagnetic waves will not leak in or out.

[0055] It should be noted that when using high-frequency signal shielding, the high-frequency signal only needs to be formed into an electromagnetic shielding mesh with a hole diameter smaller than the wavelength of the interfering electromagnetic wave to achieve electromagnetic shielding without a physical seal.

[0056] In some possible implementations, the shielding cover is a non-metallic double-layer plate with a void layer filled with metal particles.

[0057] In this embodiment, a non-metallic double-layer plate can be used to isolate the module to be isolated. Metal particles are added to the double-layer plate according to the isolation signal frequency. The metal particles can be metals such as copper, aluminum, and silver, so that the interference signal forms eddy currents in the metal particles of the double-layer metal plate, thereby achieving the shielding effect.

[0058] Furthermore, in conventional setups, high-conductivity metal shields are generally heavy and have high manufacturing costs. Therefore, this application uses a sandwich shield, i.e., a non-metallic double-layer plate, by adding high-conductivity metal particles in the middle as an EMI shielding layer, to reduce the cost of producing metal shields and increase the utilization rate of waste metal scraps.

[0059] In some possible implementations, the base plate is a metal mesh RF base plate, and the mesh of the metal mesh RF base plate is filled with at least one material, including insulating rubber and silver powder.

[0060] In this embodiment, electromagnetic interference signals are further absorbed by setting a metal mesh radio frequency base plate and filling the small holes of the metal mesh with insulating rubber, silver powder and other metal particles.

[0061] In some possible implementations, the shielding cover is made of an unsaturated semiconductor material.

[0062] In this embodiment, shielding can be achieved using an isolation plate made of unsaturated semiconductor material. For example, silicon steel can be used, as it contains numerous voids and eddy currents can be formed within the steel particles for further shielding. In some possible implementations, beryllium bronze can be used to make the shielding body, with insulating rubber material wrapped around both sides. Grounding the body can reduce the overall shielding cost. The beryllium bronze metal shield is lightweight, thin, and flexible, making it suitable for a wider range of products.

[0063] It should be noted that beryllium bronze itself can be surface treated, such as zinc plating or silver plating. If it is not plated, a rubber material can be used to directly wrap the beryllium bronze cover for direct use, in order to save shielding costs.

[0064] This application also provides a shielding method, which can be applied to, for example... Figure 3 The illustrated electronic device 200. Electronic devices 200 can be one or more, and may also include smart devices such as mobile phones and computers; however, this application embodiment does not specifically limit this.

[0065] Please see Figure 2 , Figure 2 This is a schematic flowchart of a shielding method provided in an embodiment of this application. The method may include steps S110 to S130.

[0066] Step S110: Obtain the blocking command.

[0067] In this embodiment, the shielding device can be controlled to send shielding commands via electronic devices such as computers or mobile phones. The shielding commands can be to activate the shielding device to perform shielding or to deactivate the shielding function of the shielding device, etc. This application does not limit them.

[0068] For example, shielding electromagnetic wave properties and protocols can be defined by selecting the operating conditions of the corresponding device to be shielded on a smart device.

[0069] Step S120: Determine the high-frequency electromagnetic signal transmitted between the signal transmitting board and the signal receiving board based on the shielding instruction.

[0070] In this embodiment of the application, after sending the shielding command, the specific information of the high-frequency electromagnetic signal transmitted between the current signal transmitting board and the signal receiving board can be obtained according to the shielding command, such as the frequency information of the current high-frequency electromagnetic signal.

[0071] Step S130: Generate a signal shielding area based on the high-frequency electromagnetic signal to shield the devices to be shielded from electromagnetic interference within the signal shielding area.

[0072] In this embodiment of the application, after obtaining the high-frequency electromagnetic signal, the corresponding signal shielding area can be determined by the electronic device. It can be determined whether the device to be shielded is completely covered by the signal shielding area, so as to determine that the device to be shielded has been shielded against electromagnetic interference. The signal transmitting board and the signal receiving board can form a spherical shielding space in the middle area of ​​the two boards to achieve the purpose of bidirectional EMI shielding.

[0073] In this embodiment, high-frequency electromagnetic signals are used to provide bidirectional EMI protection for circuits, components, and equipment. By utilizing the wavelength and frequency characteristics of magnetic waves, a high-frequency electromagnetic signal shielding network is designed to address multi-harmonic interference sources generated by stray magnetic fields and alternating magnetic fields. This reduces the metal plates used for shielding in existing technologies and the space required for those plates, thereby improving the quality of the product itself and reducing assembly time and material preparation time.

[0074] To ensure a more stable signal shielding area and to accommodate the electromagnetic signals generated by various stray magnetic fields in the working environment, it is necessary to consider the following:

[0075] In some embodiments, the shielding method may further include steps S140 to S160.

[0076] Step S140: Obtain the electromagnetic interference signal of the environment where the device to be shielded is located.

[0077] In the embodiments of this application, in industrial environments and electrical appliance usage scenarios, there are a large number of stray magnetic field environments, which are general EMI magnetic field environments. Alternating magnetic fields can affect electronic components that use metal shells to shield EMI. High-frequency electromagnetic wave identification devices are set up to detect electromagnetic interference signals in the environment.

[0078] Step S150: Generate control commands based on electromagnetic interference signals.

[0079] In the embodiments of this application, when it is determined that the current electromagnetic interference signal is small or large, control commands can be generated to adjust the high-frequency electromagnetic signal.

[0080] Step S160: Adjust the intensity of the high-frequency electromagnetic signal based on the control command.

[0081] In this embodiment of the application, when it is determined that there is little environmental electromagnetic interference, the frequency of the high-frequency electromagnetic signal can be reduced, that is, by adjusting the signal transmitting board and the signal receiving board, the consumption required for shielding can be reduced.

[0082] In some embodiments, the stability of high-frequency electromagnetic signals can also be detected. By continuously detecting high-frequency electromagnetic signals, shielding failure can be prevented due to excessive distortion during signal transmission.

[0083] The operating environment for the device to be shielded generally requires low EMI interference, so the device to be shielded should be placed in an optimal location.

[0084] In some embodiments, the shielding method may further include steps S170 to S180.

[0085] Step S170: Generate prompt instructions based on electromagnetic interference signals.

[0086] In this embodiment of the application, the prompting instruction may be issued by a shielding device or received by an electronic device, and may be a specific location movement prompt or alarm, etc.

[0087] Step S180: Adjust the position of the device to be shielded in its environment based on the prompt instructions.

[0088] In this embodiment of the application, when the prompt instruction is received, it is determined that the position of the device to be shielded is not in the optimal position, that is, there are a lot of interference signals. The position can be adjusted according to the prompt instruction. The device position can be changed by detecting the interference source signal to move it away from the interference source as much as possible.

[0089] Please see Figure 3 , Figure 3 This application provides a structural block diagram of an electronic device 200 that can perform the above-described shielding device. The electronic device 200 can be a smartphone, tablet computer, computer, or portable computer, etc. The electronic device 200 can complete data interaction with the shielding device.
