Please refer to FIG. 3 , which is a schematic flowchart of an antenna radiation processing method provided by an embodiment of the present application. The antenna radiation processing method provided in the embodiment of the present application is applied to an electronic device, and the specific process of the antenna radiation processing method may be as follows:

101. When the antenna signal is transmitted through the first antenna radiator and the distance between the first antenna radiator and the user is less than a preset distance threshold, obtain radiation energy distribution information of the first antenna radiator.

The electronic device includes a first antenna radiator for transmitting antenna signals. For example, the first antenna radiator can transmit 2G, 3G, 4G, 5G and other antenna signals, and can also transmit WIFI signals, Bluetooth signals, and the like.

When the electronic device transmits the antenna signal through the first antenna radiator, the distance between the first antenna radiator and the user is detected. When the obtained distance is less than the preset distance threshold, it means that the first antenna radiator is very close to the user. The energy radiated by the antenna radiator is easily absorbed by the user, causing harm to the user's health. The radiation needs to be treated at this point to protect the user. At this time, the radiation energy distribution information of the first antenna radiator is acquired. The preset distance threshold can be set as required, for example, it can be set to 30 cm, 20 cm, 10 cm, 5 cm, and so on.

In some embodiments, the radiation energy distribution information may be an antenna radiation pattern, which takes the first antenna radiator as a reference point, and the first antenna radiator has different radiation intensity signals in different directions.

102. Obtain relative position information of the first antenna radiator and the user.

The electronic device also acquires relative position information of the first antenna radiator and the user, for example, the first antenna radiator is close to the user's ear. The relative position information can be obtained through one or more distance sensors on the electronic device. For example, distance sensors are set at multiple positions of the electronic device, and the relative position information between the electronic device and the user can be determined through the distance information obtained by the multiple distance sensors, because The position of the first antenna radiator on the electronic device is fixed, and the relative position information of the first antenna radiator and the user can be obtained through the relative position information of the electronic device and the user. The camera (front camera and/or rear camera) of the electronic device can also obtain an environment image (including user image and surrounding environment image), and then obtain the relative positional relationship between the first antenna radiator and the user according to the environment image.

103. Obtain the radiation level of the corresponding user according to the relative position information and the radiation energy distribution information.

After obtaining the relative position information of the first antenna radiator and the user, and then combining the radiation energy distribution information of the first antenna radiator, the radiation level corresponding to the user can be obtained. That is, the electromagnetic radiation energy level when the user absorbs the first antenna radiator to transmit the antenna signal in the current environment is obtained.

104. When the radiation level reaches a preset level threshold, drive the first antenna radiator to rotate, so as to adjust the radiation energy distribution of the first antenna radiator and reduce the radiation level of the corresponding user.

When the radiation level of the corresponding user reaches the preset level threshold, it indicates the preset level threshold that the electromagnetic radiation energy absorbed by the current user exceeds the preset level threshold. Tighter safety thresholds. Because the signal emitted by the first antenna radiator has directionality, the radiated energy of the first antenna radiator also has different intensities of radiation energy in different directions. By driving the first antenna radiator to rotate, the radiated energy of the first antenna radiator can be adjusted. distribution, thereby reducing the radiation level of the corresponding user. For example, turning the radiant energy radiated toward the user to radiate in other directions can reduce the SAR value of the electronic device, that is, the radiant energy absorbed by the user can be reduced. At the same time, the antenna radiator emission performance of the electronic device is not affected, and the communication capability between the electronic device and the base station is not negatively affected. For example, the radiant energy radiated towards the user can be diverted to radiate in other directions, so that the radiant energy absorbed by the user can be reduced.

Please refer to FIG. 4 , FIG. 4 is another schematic flowchart of an antenna radiation processing method provided by an embodiment of the present application. The antenna radiation processing method provided in the embodiment of the present application is applied to an electronic device, and the specific process of the antenna radiation processing method may be as follows:

201 , when the antenna signal is transmitted through the first antenna radiator, obtain a transmission frequency of the antenna signal transmitted by the first antenna radiator.

The electronic device includes a first antenna radiator for transmitting antenna signals. For example, the first antenna radiator can transmit 2G, 3G, 4G, 5G and other antenna signals, and can also transmit WIFI signals, Bluetooth signals, and the like. The first antenna radiator can be located at the top of the electronic device, as the upper antenna of the electronic device, the first antenna radiator can also be located at the bottom end of the electronic device, as the lower antenna of the electronic device, the first antenna radiator can also be located in the electronic device As a side antenna of the electronic device, etc., the first antenna radiator can be set at different positions of the electronic device as required.

When the electronic device transmits the antenna signal through the first antenna radiator, the transmission frequency of the antenna signal transmitted by the first antenna radiator is acquired. Because electronic equipment has many working frequency bands (such as Band1/2/3/4/5/7/8/38/40/41 and other frequency bands), the radiation energy of the first antenna radiator (such as SAR radiation energy) in different frequency bands is not Same. When the electronic device is in some frequency bands (such as BAND38, BAND41, etc.), the impact of the radiation energy of the first antenna radiator on the human body can be within the standard, that is, the radiation level of the corresponding user is within the preset level threshold, and no processing is required. However, when the current operating frequency of the first antenna radiator is in a frequency band where the SAR value is likely to exceed the standard (such as BAND5, BAND7), the impact of the radiation energy of the first antenna radiator on the human body is likely to exceed the standard, that is, the radiation level of the corresponding user is easy to reach or Exceeds the preset level threshold and needs to be processed.

202. When the transmission frequency is in the preset frequency band, acquire the transmission power of the first antenna radiator to transmit the antenna signal.

When the transmit frequency is in a preset frequency band (eg, a frequency band in which the SAR value of the first antenna radiator is likely to exceed the standard), the transmit power of the antenna signal transmitted by the first antenna radiator is acquired.

203. When the transmit power reaches a preset power threshold, acquire the distance between the first antenna radiator and the user.

Because electronic equipment has multiple levels of transmit power, the radiated energy corresponding to different transmit powers is different. When the transmit power is lower than the preset power threshold, the radiated energy of the first antenna radiator meets the standard and has little impact on the user, so no processing is required. When the transmit power reaches the preset power threshold, the influence of the radiation energy of the first antenna radiator on the human body is likely to exceed the standard, that is, the radiation level of the corresponding user easily reaches or exceeds the preset level threshold, and needs to be processed. For example, the transmission power has five levels, and the radiation energy corresponding to the maximum five levels will exceed the standard. When the transmit power reaches the preset power threshold, the distance between the first antenna radiator and the user is acquired.

It should be noted that the preset power thresholds corresponding to different transmission frequencies may be the same or different. For example, the preset power threshold corresponding to BAND5 may be level four, and the preset power threshold corresponding to BAND7 may be level five.

It should be noted that, in some embodiments, the above steps may be determined only by the transmission frequency of the first antenna radiator, that is, the above steps are simplified as: when the transmission frequency is in the preset frequency band, obtain the first antenna radiator and the user the distance. In some other embodiments, the above steps may also be judged only by the transmit power of the first antenna radiator. That is, the above steps are simplified as: when the transmit power reaches the preset power threshold, the distance between the first antenna radiator and the user is acquired.

204. When the distance is less than the preset distance threshold, acquire the holding position of the electronic device held by the user.

When the distance between the first antenna radiator and the user is less than the preset distance threshold, it means that the first antenna radiator is very close to the user, and at this time, the holding position of the electronic device held by the user is obtained. The preset distance threshold can be set as required, for example, it can be set to 30 cm, 20 cm, 10 cm, 5 cm, and so on.

205. Determine whether the holding position blocks the first antenna radiator.

The holding position of the user will affect the performance of the first antenna radiator. For example, when the holding position just blocks the first antenna radiator, the emission performance of the first antenna radiator will be greatly reduced, and the antenna signal cannot be transmitted normally.

206. When the holding position does not block the first antenna radiator, obtain radiation energy distribution information of the first antenna radiator.

The radiation energy distribution information includes multiple radiation areas, the radiation levels corresponding to the multiple radiation areas are different, and the multiple radiation areas are distributed around the first antenna radiator. When the holding position does not block the first antenna radiator, the radiation energy distribution information of the first antenna radiator is acquired.

In some embodiments, the radiation energy distribution information may be an antenna radiation pattern, which takes the first antenna radiator as a reference point, and the first antenna radiator has different radiation intensity signals in different directions. Figure 5 shows an ideal radiation pattern of the antenna. The direction of the maximum power is the maximum energy field (main lobe) radiated by the antenna. In addition, there are side lobes and back lobes, and these parts will have radiated energy. However, because the first antenna radiator is arranged in the electronic device, and due to the influence of the display screen, back cover, middle frame, and other components in the electronic device, the actual antenna radiation pattern is not so standardized. For example, the actual antenna radiation direction Diagram 200 may be as shown in FIG. 6 .

Radiation energy distribution information can be collected in advance. For example, the antenna radiation pattern of the first antenna radiator at each position is tested in advance in the test room. It may include all frequency bands, all transmit powers, and antenna radiation patterns at all positions of the first antenna radiator. In some embodiments, conditions corresponding to similar antenna radiation patterns may be combined.

It should be noted that the electronic device may further include a second antenna radiator, and the first antenna radiator and the second antenna radiator are respectively disposed at both ends of the electronic device. For example, the first antenna radiator is arranged at the top of the electronic device as the upper antenna of the electronic device (it can also be the main antenna), and the second antenna radiator is arranged at the bottom of the electronic device as the lower antenna of the electronic device. Generally, holding the lower end of the electronic device will block the second antenna radiator, and the emission performance of the second antenna radiator is often inferior to that of the first antenna radiator. If the holding position does not block the first antenna radiator, it will most likely block the second antenna radiator. Of course, other methods can be used to detect whether the second antenna radiator is blocked, such as setting a pressure sensor on the side of the electronic device to detect the radiation of the second antenna. Whether the second antenna radiator is blocked is detected by means of the emission efficiency of the body and the like. If the second antenna radiator is not blocked, the second antenna radiator can be switched to transmit the antenna signal. If the second antenna radiator is blocked, the emission performance of the second antenna radiator is poor, and the second antenna radiator cannot be switched to transmit the antenna signal.

It should be noted that, in some embodiments, the holding position may not be detected, but only the distance may be judged. That is, the above steps are simplified as: when the distance is smaller than the preset distance threshold, the radiated energy distribution information of the first antenna radiator is acquired.

207. Obtain relative position information of the first antenna radiator and the user.

The electronic device also obtains the relative position information of the first antenna radiator and the user. For example, when using the electronic device to make a call, the display screen of the electronic device faces the user, the receiver of the electronic device (which can also be understood as the top of the electronic device) faces the user's ear, and the electronic device faces the user's ear. The microphone of the device (which can also be understood as the bottom end of the electronic device) faces the user's mouth, and the first antenna radiator is arranged at the top. Specifically, the relative position information can be obtained through one or more distance sensors on the electronic device. For example, distance sensors are set at multiple positions of the electronic device, and the relative positions of the electronic device and the user are determined through the distance information obtained by the multiple distance sensors. Since the position of the first antenna radiator on the electronic device is fixed, the relative position information of the first antenna radiator and the user can be obtained through the relative position information of the electronic device and the user. The camera (front camera and/or rear camera) of the electronic device can also obtain an environment image (including user image and surrounding environment image), and then obtain the relative positional relationship between the first antenna radiator and the user according to the environment image.

For another example, when using an electronic device to make a call, the display screen of the electronic device faces the user, the user receives the sound of the electronic device through the headset, the microphone of the electronic device (which can also be understood as the bottom end of the electronic device) faces the user's mouth, and the receiver of the electronic device (also It can be understood that the top of the electronic device is far away from the user. If the first antenna radiator is set at the bottom, other antenna radiators can be switched to transmit signals. If the first antenna radiator is set at the top, the first antenna radiator is far away from the user. No processing of the radiated energy of the first antenna radiator is required.

208. Determine the radiation area where the user is located as the target radiation area according to the relative position information.

After obtaining the relative position information of the first antenna radiator and the user, combined with the radiation energy distribution information of the first antenna radiator, the radiation area where the user is located can be obtained, and the radiation area where the user is located is the target radiation area.

209. Obtain the radiation level of the corresponding user according to the radiation level corresponding to the target radiation area.

There may be only one target radiation area, and the radiation level corresponding to the target radiation area is the radiation level of the corresponding user.

There may be multiple target radiation areas, and it may also be understood that the user is in multiple radiation areas. In this case, the radiation area with the highest radiation level may be used as the radiation level corresponding to the user.

210. When the radiation level reaches a preset level threshold, drive the first antenna radiator to rotate, so as to adjust the radiation energy distribution of the first antenna radiator and reduce the radiation level of the corresponding user.

When the radiation level of the corresponding user reaches the preset level threshold, it indicates the preset level threshold that the electromagnetic radiation energy absorbed by the current user exceeds the preset level threshold. Tighter safety thresholds. Because the signal emitted by the first antenna radiator has directionality, the radiated energy of the first antenna radiator also has different intensities of radiation energy in different directions. By driving the first antenna radiator to rotate, the radiated energy of the first antenna radiator can be adjusted. distribution, thereby reducing the radiation level of the corresponding user. For example, the adjusted antenna radiation pattern 200 may be as shown in FIG. 7 , combined with FIG. 6 , from the antenna radiation pattern 200 shown in FIG. 6 to the antenna radiation pattern 200 shown in FIG. 7 , corresponding to the radiation area of the user decrease. It can reduce the SAR value of electronic equipment, greatly reduce the radiation impact of electronic equipment on users, and at the same time does not affect the antenna radiator emission performance of electronic equipment, and will not have a negative impact on the communication capability of electronic equipment and base stations. For example, the radiant energy radiated towards the user can be diverted to radiate in other directions, so that the radiant energy absorbed by the user can be reduced.

Please refer to FIG. 8 , which is a schematic diagram of a third structure of an electronic device provided by an embodiment of the present application. FIG. 8 is a partial schematic diagram of the interior of the electronic device. The electronic device 100 provided in this embodiment of the present application includes a first antenna radiator 50 , a distance sensor 60 and a processor 70 .

The first antenna radiator 50 is disposed in the electronic device 100, and the first antenna radiator 50 is used for transmitting antenna signals. For example, the first antenna radiator 50 may transmit antenna signals such as 2G, 3G, 4G, and 5G, and may also transmit WIFI signals, Bluetooth signals, and the like. The first antenna radiator 50 may be located at the top of the electronic device 100 as an upper antenna of the electronic device. In some other embodiments, the first antenna radiator may also be located at the bottom end of the electronic device, as the lower antenna of the electronic device, the first antenna radiator may also be located at the side of the electronic device, as a side antenna of the electronic device, etc., The first antenna radiator can be set at different positions of the electronic device as required.

The distance sensor 60 is disposed adjacent to the first antenna radiator 50, and the distance sensor 60 is used to obtain the distance between the first antenna radiator 50 and the user.

The processor 70 is electrically connected to the distance sensor 60. The processor 70 obtains the relative position information of the first antenna radiator 50 and the user and the radiated energy distribution information of the first antenna radiator 50. The processor 70 is further configured to obtain the relative position information according to the relative position information and radiation energy distribution information to obtain the radiation level of the corresponding user, and when the radiation level reaches the preset level threshold, drive the first antenna radiator 50 to rotate to adjust the radiation energy distribution of the first antenna radiator and reduce the radiation of the corresponding user. grade.

When the radiation level of the corresponding user reaches the preset level threshold, it indicates the preset level threshold that the electromagnetic radiation energy absorbed by the current user exceeds the preset level threshold. Tighter safety thresholds. Because the signal transmitted by the first antenna radiator 50 has directionality, the radiated energy of the first antenna radiator 50 also has radiation energy of different intensities in different directions. By driving the first antenna radiator 50 to rotate, the first antenna radiator can be adjusted. 50% of the radiation energy distribution, thereby reducing the radiation level of the corresponding user. The SAR value of the electronic device can be reduced, greatly reducing the radiation impact of the electronic device 100 on the user, without affecting the emission performance of the first antenna radiator of the electronic device 100, and will not have a negative impact on the communication capability of the electronic device 100 and the base station. For example, the radiated energy radiated by the first antenna radiator 50 toward the user is turned to be radiated in other directions, so that the radiated energy absorbed by the user can be reduced.

The electronic device 100 further includes a rotating shaft 80 arranged in the electronic device 100 , the first antenna radiator 50 is disposed on the rotating shaft 80 , the processor 70 is rotatably connected to the rotating shaft 80 , and the processor 70 can drive the rotating shaft 80 to rotate.

Please refer to FIG. 9 , which is a schematic diagram of a fourth structure of an electronic device provided by an embodiment of the present application. The electronic device 100 may further include a motor 82 , and the processor 70 drives the rotating shaft 80 to rotate through the motor 82 . The first antenna radiator 50 may be disposed inside the rotating shaft 80 , may also be attached to the outer surface of the rotating shaft 80 , or may be partially embedded in the rotating shaft 80 and partially disposed outside the rotating shaft 80 . The first antenna radiator 50 can be in the shape of a bar. The antenna signal transmitted by the first antenna radiator 50 has directionality. When the rotating shaft 80 rotates, the first antenna radiator 50 and the display screen of the electronic device 100 form different angles. The radiated energy distribution of the antenna radiator 50 also has a different relative positional relationship with the display screen.

It should be noted that the electronic device can also obtain the rotating shaft in other ways, such as through magnetic drive, there is a magnetic element on the rotating shaft, and an electromagnetic element is also provided in the electronic device. same or opposite magnetism. The processor drives the magnetic element by controlling whether the electromagnetic element is energized, thereby driving the rotation of the shaft.

Please refer to FIG. 10 . FIG. 10 is a schematic diagram of a fifth structure of an electronic device provided by an embodiment of the present application. The electronic device 100 further includes a fixing bracket 84, the fixing bracket 84 includes a threaded hole (not shown in the figure), and the rotating shaft 50 is arranged in the threaded hole and is threadedly connected with the threaded hole. When the rotating shaft 80 rotates, the rotating shaft 80 rotates along the diameter of the rotating shaft. while rotating in the axial direction of the shaft through the threaded hole.

The motor 82 of the electronic device 100 or other driving elements (such as multiple sets of magnetic elements) can drive the rotating shaft 80 to rotate, and the rotating shaft 80 can rotate in the threaded hole. It can also move along the axial direction of the rotating shaft. The first antenna radiator 50 disposed on the rotating shaft 80 can not only rotate in the direction perpendicular to the display screen, but also move in the direction parallel to the display screen, so as to avoid the radiant energy area from the user as much as possible, or to the area with large radiant energy. Avoid users. For example, the motor 82 is connected to the inside of the electronic device 100 through the slider. When the rotating shaft 80 moves, the rotating shaft 80 rotates and moves through the threaded hole, which drives the motor 82 to slide through the slider.

Radiation energy distribution information can be collected in advance. For example, the antenna radiation pattern of the first antenna radiator at each position is tested in advance in the test room. It may include all frequency bands, all transmit powers, and antenna radiation patterns at all positions of the first antenna radiator. Wherein, all the positions of the first antenna radiator include different rotation angles of the drive shaft and different moving positions, which can also be understood as rotating at different angles when moving to different positions. In some embodiments, conditions corresponding to similar antenna radiation patterns may be combined.

The processor 70 determines the rotation direction and angle of the driving shaft 80 according to the relative position information and the radiation energy distribution information. The rotating shaft 80 can be driven to move forward in the first direction, or the rotating shaft can be reversed to move in the second direction, and the angle of rotation of the rotating shaft 80 can also be understood as not only changing the angle between the first antenna radiator 50 and the user, but also changing the angle between the first antenna radiator 50 and the user. The distance of the first antenna radiator 50 from the user can be changed. For example, when the user places the electronic device 100 beside the ear, one side of the electronic device 100 is adjacent to the ear and the other side faces the back of the user's head, at this time, the first antenna radiator 50 is driven to move towards the back of the user's head. For another example, the user places the electronic device 100 next to the ear, one side of the ear is adjacent to the other side facing the front of the user's face, at this time, the first antenna radiator 50 is driven to move in front of the user's face.

Please continue to refer to FIG. 1 , the electronic device further includes a receiver 14 , and the receiver 14 and the first antenna radiating 50 are disposed at the same end of the electronic device. The receiver 14 and the first antenna radiator 50 are both disposed at the top of the electronic device 100 , and the first antenna radiator 50 serves as the upper antenna (may also be the main antenna) of the electronic device 100 . In some embodiments, the top of the electronic device may further include a front camera, a light sensor, and the like.

In some embodiments, the processor 70 may also be configured to, when the antenna signal is transmitted through the first antenna radiator 50, obtain the transmission frequency of the antenna signal transmitted by the first antenna radiator 50. When the transmit frequency is in the preset frequency band, the processor 70 acquires the transmit power of the transmit antenna signal of the first antenna radiator 50 . When the transmit power reaches the preset power threshold, the processor 70 obtains the distance between the first antenna radiator 50 and the user. When the distance is less than the preset distance threshold, the processor 70 acquires the holding position of the electronic device 100 held by the user. The processor 70 determines whether the holding position blocks the first antenna radiator 50 . When the holding position does not block the first antenna radiator 50 , the processor 70 acquires the radiation energy distribution information of the first antenna radiator 50 . The processor 70 acquires relative position information of the first antenna radiator 50 and the user. The processor 70 determines that the radiation area where the user is located is the target radiation area according to the relative position information. The processor 70 obtains the radiation level of the corresponding user according to the radiation level corresponding to the target radiation area. When the radiation level reaches the preset level threshold, the processor 70 drives the first antenna radiator 50 to rotate to adjust the radiation energy distribution of the first antenna radiator 50 and reduce the radiation level of the corresponding user.

For the specific manner in which the processor 70 implements the above functions, reference may be made to the above embodiments of the antenna radiation processing method, and details are not described herein again. It should be noted that, in some embodiments, the processor 70 may only determine the transmission frequency of the first antenna radiator 50, that is, when the transmission frequency is in the preset frequency band, the processor 70 obtains the first antenna radiator 50 and the distance of the user. In some other embodiments, the processor 70 may also make the judgment only by the transmit power of the first antenna radiator 50, and the above steps may be judged only by the transmit power. That is, when the transmit power reaches the preset power threshold, the processor 70 acquires the distance between the first antenna radiator 50 and the user. In other embodiments, the holding position may not be detected, but only the distance may be judged. That is, when the distance is smaller than the preset distance threshold, the processor 70 acquires the radiation energy distribution information of the first antenna radiator 70 .

It should be noted that, the first antenna radiator in the embodiment of the present application can not only transmit antenna signals, but also receive antenna signals.

An embodiment of the present application further provides a storage medium, where a computer program is stored in the storage medium, and when the computer program runs on the computer, the computer executes the antenna radiation processing method of any one of the foregoing embodiments.

For example, in some embodiments, when the computer program is run on a computer, the computer performs the following steps:

When an antenna signal is transmitted through the first antenna radiator, and the distance between the first antenna radiator and the user is less than a preset distance threshold, acquiring radiation energy distribution information of the first antenna radiator;

acquiring relative position information of the first antenna radiator and the user;

obtaining the radiation level corresponding to the user according to the relative position information and the radiation energy distribution information;

When the radiation level reaches a preset level threshold, the first antenna radiator is driven to rotate, so as to adjust the radiation energy distribution of the first antenna radiator and reduce the radiation level corresponding to the user.
