[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.
[0043] Before providing a detailed explanation of the terminal protection device and protection method provided in the embodiments of this application, the application scenarios and implementation environment involved in the embodiments of this application will be introduced first.
[0044] The terminal protection method provided in this application can be applied to any terminal containing an antenna segment, such as mobile phones, laptops, smartwatches, Bluetooth headsets, etc. During terminal use, if the terminal's antenna segment is about to overheat and be damaged due to proximity to an electromagnetic radiation field (or electromagnetic field, also known as electromagnetic wave) with a frequency close to the antenna segment's operating frequency (or resonant frequency), the terminal's protection device can protect the antenna segment according to the protection method provided in this application, thereby preventing the antenna segment from overheating and being damaged.
[0045] Among them, the electromagnetic radiation fields that the terminal may be near include, but are not limited to, the electromagnetic fields generated by devices such as induction cookers, microwave ovens, and medical devices that emit radiation as radiation sources.
[0046] Please refer to Figure 1 , Figure 1 This is a schematic diagram illustrating an implementation environment according to an exemplary embodiment. The implementation environment includes a terminal 101 and a radiation source 102. The terminal 101 includes an antenna segment, and the radiation source can radiate electromagnetic waves. The terminal 101 may be located within the electromagnetic waves radiated by the radiation source 102 due to its proximity to the radiation source 102. The terminal 101 is used to protect the antenna segment within the terminal according to the terminal protection method provided in this application embodiment, to prevent the antenna segment from overheating and being damaged.
[0047] Those skilled in the art should understand that the above-mentioned terminals and radiation sources are merely examples. Other existing or future terminals or radiation sources that are applicable to the embodiments of this application should also be included within the scope of protection of the embodiments of this application, and are hereby incorporated by reference.
[0048] It should be noted that the application scenarios and implementation environments described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the emergence of new application scenarios and the evolution of implementation environments, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.
[0049] The protection device for the terminal provided in the embodiments of this application will now be explained in detail.
[0050] Figure 2 This is a schematic diagram of a protection device for a terminal provided in an embodiment of this application. The protection device includes a grounding switch, and a first position of the antenna segment inside the terminal is connected to the grounding switch (GND in the figure represents grounding). The first position is located at a non-endpoint of the antenna segment. The protection device is used to acquire the usage status of the antenna segment, including power and / or temperature. When the usage status meets the antenna protection conditions, the grounding switch is turned on to change the operating frequency of the antenna segment.
[0051] In other words, by connecting a grounding switch at the first position of the antenna segment, the protection device can activate the grounding switch when it detects that the power and / or temperature of the antenna segment meet the antenna protection conditions, thereby changing the operating frequency of the antenna segment and preventing the antenna segment from coupling with high-intensity electromagnetic waves, thus preventing the antenna segment from overheating and being damaged.
[0052] The antenna protection conditions may include the antenna segment's power exceeding a power threshold and / or its temperature exceeding a temperature threshold. The power and temperature thresholds can be flexibly set according to actual conditions, and this application embodiment does not limit this. For example, different power and / or temperature thresholds can be set for different types of terminals and different terminal usage environments.
[0053] As an example, the power threshold is 25 dBm (decibels per milliwatt) and the temperature threshold is 90 °C (degrees Celsius).
[0054] See Figure 3 In one possible implementation, the protection device includes a detection component and a processor. The detection component is connected to the processor, which is also connected to a grounding switch. The detection component is used to acquire information about the usage status of the antenna segment. The processor is used to activate the grounding switch when the usage status meets the antenna protection conditions.
[0055] In some embodiments, the detection component can directly send the power and / or temperature of the antenna segment to the processor, which then determines whether the antenna segment's usage meets the antenna protection conditions based on the power and / or temperature. For example, the processor can perform a threshold judgment on the power and / or temperature to obtain a threshold judgment result (i.e., a detection result), which indicates whether the antenna segment's usage meets the antenna protection conditions.
[0056] In other embodiments, the detection component determines whether the antenna segment's usage meets antenna protection conditions based on the antenna segment's power and / or temperature, and sends the detection result to the processor. The detection result indicates whether the antenna segment's usage meets the antenna protection conditions. For example, the detection component can perform a threshold judgment on the power and / or temperature, and send the threshold judgment result (i.e., the detection result) to the processor. The threshold judgment result indicates whether the antenna segment's usage meets the antenna protection conditions.
[0057] In one possible implementation, the detection component includes a power detection unit and / or a temperature detection unit. See also Figure 4 The power detection unit is connected to the antenna segment, for example, to one end of the antenna segment. The power detection unit is used to detect the power of the antenna segment. The temperature detection unit is located at a distance less than the reference distance from the antenna segment. The temperature detection unit is used to detect the temperature of the antenna segment. See also... Figure 5 The temperature detection unit does not need to be connected to the antenna segment; it can be placed near the antenna segment. The reference distance can be set according to the actual situation, and the location of the temperature detection unit can be determined according to the structure of each device / circuit. This application does not limit this.
[0058] The power detection unit can be any component or circuit capable of detecting power, and there are no restrictions on this.
[0059] In one possible implementation, the power detection unit includes a coupling component connected to an antenna segment, such as... Figure 6 As shown, the coupling component is connected to one end of the antenna segment and is used to detect the power of the antenna segment. As an example, the coupling component is used to sense the electromagnetic field generated by the antenna segment, thereby detecting the power of the antenna segment based on the sensed electromagnetic field.
[0060] See Figure 7 In one possible implementation, the coupling components include a coupler and a power detection IC (integrated circuit). The coupler is connected to the antenna segment (e.g., to one end of the antenna segment) and also to the power detection IC, which is further connected to a processor. The coupler is used to sense the electromagnetic field generated by the antenna segment, and the power detection IC is used to determine the power of the antenna segment based on the electromagnetic field sensed by the coupler.
[0061] The coupler can be a reverse coupler, a bidirectional coupler, or other possible couplers, and this application embodiment does not limit this. The power detection IC can be any integrated circuit or component capable of calculating power, and this application embodiment does not limit this.
[0062] The temperature detection unit can be any component or circuit capable of detecting temperature, and there are no restrictions on this.
[0063] In one possible implementation, the temperature detection unit includes a thermistor or a temperature sensor.
[0064] In this embodiment, the number of first positions is equal to or greater than one. That is, a grounding switch can be connected to one or more positions on the antenna segment, and the one or more first positions divide the antenna segment into two or more segments. Different numbers of segments result in different changes in the operating frequency of the antenna segment after the grounding switch is turned on, and each sub-antenna segment can absorb different amounts of electromagnetic energy, thus producing different protection effects.
[0065] In one possible implementation, the first position is at the electrical length i / n of the antenna segment, where n equals the total number of the first positions plus 1, and i is greater than or equal to 1 and less than or equal to n. That is, the antenna segment is divided equally according to its electrical length, and a grounding switch is connected at each segment.
[0066] like Figure 7 As shown, n equals 2, the first position is at 1 / 2 of the electrical length of the antenna segment, the number of first positions is equal to 1, and the antenna segment is divided into two equal parts according to its electrical length. For example... Figure 8As shown, n equals 4, the first position is 1 / 4 of the electrical length of the antenna segment, the number of first positions is 3, and the antenna segment is divided into four segments according to its electrical length.
[0067] It should be understood that dividing the antenna segment equally according to its electrical length ensures that after the grounding switch is turned on, the operating frequency of each sub-antenna segment is basically the same and is significantly increased. This can minimize the electromagnetic energy coupled by all sub-antenna segments, thereby minimizing the heat generation of the antenna segment.
[0068] As an example, in a related technical solution where the antenna segment is not connected to a grounding switch, taking the case where the antenna segment senses strong electromagnetic radiation and absorbs 10W (watts) of electromagnetic energy, resulting in severe overheating, if the technical solution provided in this application is adopted, and the antenna segment is divided into two equal segments according to its electrical length, then after the grounding switch is turned on, the original 10W of electromagnetic energy may only be absorbed by each of the divided sub-antenna segments by 0.5W, and the two sub-antenna segments absorb a total of 1W of electromagnetic energy, thereby avoiding severe overheating.
[0069] Of course, in some other possible implementations, the antenna may not be divided equally according to its electrical length. For example, a grounding switch may be connected only at 1 / 3 of the antenna's electrical length. In this way, after the grounding switch is turned on, the operating frequency of the shorter sub-antenna segment increases significantly, and the electromagnetic energy it can absorb decreases significantly. While the operating frequency of the longer sub-antenna segment increases relatively less, it can still reduce the absorption of some electromagnetic energy, thereby reducing the heat generation of the antenna segment.
[0070] As an example, taking the original 10W of electromagnetic energy as an example, the shorter sub-antenna segment after division may only absorb 0.1W of electromagnetic energy, while the longer sub-antenna segment after division may absorb 1W or 2W of electromagnetic energy. Although 1W / 2W is greater than 0.1W, it is still much less than 10W.
[0071] To avoid the situation where the antenna segments are not evenly divided, and the longer sub-antenna segments after division may still absorb more electromagnetic energy, in practical applications, the antenna segments can be divided evenly according to their electrical length.
[0072] It should be understood that, in reality, the physical shape of antenna segments is not necessarily regular. Therefore, dividing the antenna segment equally according to its electrical length may not yield the same result as dividing it equally according to its physical length. If the division is based on the physical length, the resulting sub-antenna segments will have different electrical lengths. Consequently, after the grounding switch is turned on, the absorption of electromagnetic energy by these sub-antenna segments will vary significantly. To optimize the protection effect, in practical applications, the antenna segments can be divided equally according to their electrical length.
[0073] In one possible implementation, the protection device is also used to alert the antenna segment to the risk of damage when the usage conditions meet the antenna protection conditions, and to disconnect the grounding switch to restore the operating frequency of the antenna segment after receiving a confirmation operation indicating that the risk of damage has been eliminated.
[0074] In other words, the protection device can provide a warning (i.e., an early warning) about the risk of damage to the antenna segment, reminding the user to keep the terminal away from the radiation source. Once the user has manually confirmed that the risk of damage to the antenna segment has been eliminated, the protection device will restore the operating frequency of the antenna segment to enable the terminal to work normally.
[0075] See Figure 9 In one possible implementation, the protection device also includes an early warning unit, which is used to alert the antenna segment to the risk of damage when the usage conditions meet the antenna protection requirements.
[0076] As an example, the early warning unit is connected to the processor. When the usage conditions meet the antenna protection requirements, the processor sends a first command to the early warning unit, instructing the unit to warn of the potential damage risk to the antenna segment. Upon receiving the first command, the early warning unit warns of the potential damage risk to the antenna segment. After receiving confirmation that the damage risk has been eliminated, the processor controls the grounding switch to open.
[0077] The early warning unit may include a voice prompt module for providing voice alerts regarding the risk of damage to the antenna segment. The early warning unit may also include a graphic and / or text prompt module for providing graphic and / or textual alerts regarding the risk of damage to the antenna segment.
[0078] The voice prompt module may include a speaker in the terminal (such as...) Figure 10 Components such as amplifiers, etc., are shown. The graphic prompt module may include a display screen in the terminal, etc.
[0079] As an example, taking a mobile phone as the terminal, a user holding the phone is approaching an induction cooker with severe electromagnetic leakage. The antenna segment experiences a rapid increase in power and temperature due to coupling with the electromagnetic waves radiated by the induction cooker. If the power detection unit detects that the power exceeds a power threshold, and / or the temperature detection unit detects that the temperature exceeds a temperature threshold, the processor controls the grounding switch to conduct and triggers a voice warning. After hearing the voice warning, the user can move the phone away from the induction cooker and operate the phone to eliminate the risk. After receiving confirmation that the risk of damage has been eliminated, the processor controls the grounding switch to disconnect.
[0080] In one possible implementation, the processor includes a first pin (also referred to as a first port) connected to a grounding switch. The processor uses a control signal transmitted through the first pin to control the on / off state of the grounding switch. It should be understood that the processor may also include other pins, which are not limited in this embodiment.
[0081] As an example, such as Figure 10 As shown, the first pin can be a GPIO (General-purpose Input / Output) pin, and the control signals transmitted by the GPIO pin can be called GPIO control signals. Of course, the first pin can also be any other pin on the processor besides the GPIO pin, and this application embodiment does not limit this.
[0082] In one possible implementation, the grounding switch is an RF (Radio Frequency) switch, such as... Figure 10 As shown, the grounding switch can be an SPST (Single Pole Single Throw) switch. The grounding switch can also be other types of switches, and this application does not limit this type.
[0083] It should be understood that, Figures 2 to 10 The device structure shown can be flexibly combined and used according to actual conditions, and the embodiments of this application do not limit it.
[0084] The terminal protection method provided in the embodiments of this application will now be explained in detail.
[0085] Figure 11 This is a flowchart of a terminal protection method provided in an embodiment of this application. This method can be applied to a terminal protection device, which may be... Figures 2 to 10 Any of the protective devices shown. Please refer to... Figure 11 The method includes the following steps.
[0086] Step 1101: Obtain the usage status of the antenna segments within the terminal, including power and / or temperature.
[0087] As an example, the protection device includes a power detection unit to obtain the power of the antenna segment; and / or, the protection device includes a temperature detection unit to obtain the temperature of the antenna segment. Specific implementation details can be found in the description of the device embodiments above, and will not be repeated here.
[0088] Step 1102: When the usage conditions meet the antenna protection requirements, turn on the grounding switch connected to the first position on the antenna segment to change the operating frequency of the antenna segment. The first position is located at a non-endpoint of the antenna segment.
[0089] The antenna protection conditions may include the antenna segment's power exceeding a power threshold and / or its temperature exceeding a temperature threshold. The power and temperature thresholds can be flexibly set according to actual conditions, and this application embodiment does not limit this. For example, different power and / or temperature thresholds can be set for different types of terminals and different terminal usage environments.
[0090] As an example, the power threshold is 30 dBm and the temperature threshold is 100 °C.
[0091] In this embodiment, the number of first positions is equal to or greater than one. That is, a grounding switch can be connected to one or more positions on the antenna segment, and the one or more first positions divide the antenna segment into two or more segments. Different numbers of segments result in different changes in the operating frequency of the antenna segment after the grounding switch is turned on, and each sub-antenna segment can absorb different amounts of electromagnetic energy, thus producing different protection effects.
[0092] In one possible implementation, the first position is at the electrical length i / n of the antenna segment, where n equals the total number of the first positions plus 1, and i is greater than or equal to 1 and less than or equal to n. That is, the antenna segment is divided equally according to its electrical length, and a grounding switch is connected at each segment.
[0093] like Figure 7 As shown, n equals 2, the first position is at 1 / 2 of the electrical length of the antenna segment, the number of first positions is equal to 1, and the antenna segment is divided into two equal parts according to its electrical length. For example... Figure 8 As shown, n equals 4, the first position is 1 / 4 of the electrical length of the antenna segment, the number of first positions is 3, and the antenna segment is divided into four segments according to its electrical length.
[0094] It should be understood that dividing the antenna segment equally according to its electrical length ensures that after the grounding switch is turned on, the operating frequency of each sub-antenna segment is basically the same and is significantly increased. This can minimize the electromagnetic energy coupled by all sub-antenna segments, thereby minimizing the heat generation of the antenna segment.
[0095] Of course, in some other possible implementations, the antenna may not be divided equally according to its electrical length, and this application does not limit this.
[0096] In one possible implementation, if the usage conditions meet the antenna protection requirements, a warning can be issued regarding the risk of damage to the antenna segment. Upon receiving confirmation that the risk of damage has been eliminated, the grounding switch is disconnected to restore the operating frequency of the antenna segment. Specific implementation details can be found in the description of the device embodiment above, and will not be repeated here.
[0097] In other words, the protection device can alert the user to the risk of damage to the antenna segment, reminding them to keep the terminal away from the radiation source. Once the user has manually confirmed that the risk of damage to the antenna segment has been eliminated, the protection device will restore the operating frequency of the antenna segment to allow the terminal to work normally.
[0098] In summary, in this embodiment of the application, by connecting a grounding switch at the first position of the antenna segment within the terminal, the protection device can activate the grounding switch when it detects that the power and / or temperature of the antenna segment meet the antenna protection conditions. This changes the operating frequency of the antenna segment, breaks the resonance state of the antenna segment, and prevents the antenna segment from coupling with high-intensity electromagnetic waves, thereby preventing the antenna segment from overheating and being damaged.

[0100] The acquisition module 1201 is used to acquire the usage status of the antenna segment within the terminal, including power and / or temperature.
[0101] Control module 1202 is used to turn on the grounding switch connected to a first position on the antenna segment to change the operating frequency of the antenna segment when the antenna protection conditions are met. The first position is located at a non-endpoint of the antenna segment. The antenna protection conditions include the power exceeding a power threshold and / or the temperature exceeding a temperature threshold.

[0108] The acquisition module 1201 is used to acquire the usage status of the antenna segment through the detection component;
[0109] The control module 1202 is used to turn on the grounding switch via the processor when the antenna protection conditions are met.
[0110] In one possible implementation, the detection component includes a power detection unit and / or a temperature detection unit; the power detection unit is connected to the antenna segment.
[0111] The acquisition module 1201 is used to detect the power of the antenna segment through the power detection unit and / or to detect the temperature of the antenna segment through the temperature detection unit, wherein the distance between the temperature detection unit and the antenna segment is less than a reference distance.
[0112] In one possible implementation, the power detection unit includes a coupler; the temperature detection unit includes a thermistor or a temperature sensor.

[0114] In this embodiment, by connecting a grounding switch at the first position of the antenna segment within the terminal, the protection device can activate the grounding switch when it detects that the power and / or temperature of the antenna segment meet the antenna protection conditions. This changes the operating frequency of the antenna segment, breaks its resonant state, and prevents the antenna segment from coupling with high-intensity electromagnetic waves, thereby preventing the antenna segment from overheating and being damaged.

[0130] Accelerometer 1311 can detect the magnitude of acceleration along the three axes of a coordinate system established by terminal 1300. For example, accelerometer 1311 can be used to detect the components of gravitational acceleration along the three axes. Processor 1301 can control display screen 1305 to display the user interface in either a landscape or portrait view based on the gravitational acceleration signal acquired by accelerometer 1311. Accelerometer 1311 can also be used for games or for acquiring user motion data.
[0131] The gyroscope sensor 1312 can detect the orientation and rotation angle of the terminal 1300. The gyroscope sensor 1312, in conjunction with the accelerometer sensor 1311, can collect 3D motion data from the user on the terminal 1300. Based on the data collected by the gyroscope sensor 1312, the processor 1301 can perform the following functions: motion sensing (e.g., changing the UI based on the user's tilt), image stabilization during shooting, game control, and inertial navigation.
[0132] The pressure sensor 1313 can be disposed on the side bezel of the terminal 1300 and / or on the lower layer of the display screen 1305. When the pressure sensor 1313 is disposed on the side bezel of the terminal 1300, it can detect the user's grip signal on the terminal 1300, and the processor 1301 can perform left / right hand recognition or quick operation based on the grip signal collected by the pressure sensor 1313. When the pressure sensor 1313 is disposed on the lower layer of the display screen 1305, the processor 1301 can control the operable controls on the UI interface based on the user's pressure operation on the display screen 1305. The operable controls include at least one of button controls, scroll bar controls, icon controls, and menu controls.
[0133] The fingerprint sensor 1314 is used to collect the user's fingerprint. The processor 1301 identifies the user's identity based on the fingerprint collected by the fingerprint sensor 1314, or the fingerprint sensor 1314 identifies the user's identity based on the collected fingerprint. When the user's identity is identified as trusted, the processor 1301 authorizes the user to perform relevant sensitive operations, including unlocking the screen, viewing encrypted information, downloading software, making payments, and changing settings. The fingerprint sensor 1314 can be located on the front, back, or side of the terminal 1300. When the terminal 1300 has physical buttons or a manufacturer's logo, the fingerprint sensor 1314 can be integrated with the physical buttons or manufacturer's logo.
[0134] An optical sensor 1315 is used to collect ambient light intensity. In some embodiments, the processor 1301 can control the display brightness of the display screen 1305 based on the ambient light intensity collected by the optical sensor 1315. Specifically, when the ambient light intensity is high, the display brightness of the display screen 1305 is increased; when the ambient light intensity is low, the display brightness of the display screen 1305 is decreased. In other embodiments, the processor 1301 can also dynamically adjust the shooting parameters of the camera assembly 1306 based on the ambient light intensity collected by the optical sensor 1315.
[0135] The proximity sensor 1316, also known as a distance sensor, is typically located on the front panel of the terminal 1300. The proximity sensor 1316 is used to detect the distance between the user and the front of the terminal 1300. In some embodiments, when the proximity sensor 1316 detects that the distance between the user and the front of the terminal 1300 is gradually decreasing, the processor 1301 controls the display screen 1305 to switch from a screen-on state to a screen-off state; when the proximity sensor 1316 detects that the distance between the user and the front of the terminal 1300 is gradually increasing, the processor 1301 controls the display screen 1305 to switch from a screen-off state to a screen-on state.
