Referring to fig. 4, fig. 4 is a schematic front structure view of an antenna radiator portion of an electronic device extending out of a receiving space according to a first embodiment of the present application. In this embodiment, the device body 100 includes a battery cover 110 and a display 120. The battery cover 110 includes a cover plate 111 and a frame 112 fixedly connected to each other.

The receiving space 100a is used for receiving the sliding seat 500, the antenna radiator 200, the driving member 600, the detector 300, and the controller 400. In the present embodiment, the opening 100b is formed in the frame 112. The display screen 120 may be a liquid crystal display screen or an organic light emitting diode display screen, and the display screen 120 may only have a display function or may also have a display and touch function.
Further, the electronic device 10 further includes other functional modules 700, the other functional modules 700 are disposed on the sliding seat 500, and the other functional modules 700 include but are not limited to at least one of a camera module, a receiver module, and a proximity sensor module.

In this embodiment, when the power of the electromagnetic wave signal radiated by the antenna radiator 200 is greater than a first preset power, the distance between the antenna radiator 200 and the user is less than a first preset distance, and the ratio of the user to the absorption of the electromagnetic wave signal is greater than a first preset threshold, the controller 400 sends a control signal, where the control signal is used to control the driving member 600 to drive the sliding seat 500 to move a first distance compared with the device body 100, so that the distance between the antenna radiator 200 and the user is increased, and the ratio of the user to the absorption of the electromagnetic wave signal is less than the first preset threshold.
In this embodiment, when the power of the electromagnetic wave signal radiated by the antenna radiator 200 is greater than a first preset power, when the distance from the antenna radiator 200 to the user is less than a first preset distance, and when the absorption ratio of the user to the electromagnetic wave signal is greater than a first preset threshold, it is determined that the electromagnetic wave signal is closer to the user, and the electromagnetic wave signal may cause adverse effects on the health of the user. The controller 400 controls the driving member 600 to drive the sliding seat 500 to move a first distance compared to the device body 100, and since the antenna radiator 200 is located on the sliding seat 500, correspondingly, the antenna radiator 200 is driven by the sliding seat 500 to move the first distance compared to the device body 100, at this time, the distance between the antenna radiator 200 and the user is increased, and thus the ratio of the absorption of the user on the electromagnetic wave signal is smaller than a first preset threshold. When the ratio of the absorption of the electromagnetic wave signals by the user is smaller than the first preset threshold, it is determined that the antenna radiator 200 does not have an adverse effect on the health of the user.
Further, when the control signal controls the driving member 600 to drive the sliding seat 500 to move for a first distance compared to the device body 100, the control signal controls the driving member 600 to drive the sliding seat 500 to move for a first sub-distance at a first speed, and then controls the driving member 600 to drive the sliding seat 500 to move for a second sub-distance at a second speed, wherein the first speed is greater than the second speed, and after the sliding seat 500 moves for the first sub-distance, the attenuation of the absorption ratio of the electromagnetic wave signal by the user is greater than a preset ratio.
In this embodiment, after the sliding seat 500 moves the first sub-distance, since the distance between the user and the electromagnetic wave signal increases, the absorption ratio of the user to the electromagnetic wave signal is significantly attenuated, and the adverse effect of the electromagnetic wave signal on the user is significantly reduced. The preset ratio may be, but is not limited to, 85%. It can be understood that, when the ratio of the absorption of the electromagnetic wave signal by the user is greater than the first preset threshold, the sliding seat 500 moves at a faster speed for a first sub-distance, so as to ensure that the ratio of the absorption of the electromagnetic wave signal by the user is attenuated quickly. In addition, when the attenuation of the electromagnetic wave signal radiated by the antenna radiator 200 is greater than the predetermined ratio, the moving speed of the sliding seat 500 is reduced, so that the electric quantity of the electronic device 10 can be saved. The present embodiment balances the elimination of the adverse effect of the electromagnetic wave signal radiated by the antenna radiator 200 on the user and the power consumption of the electronic device 10, and rapidly improves the adverse effect of the electromagnetic wave signal radiated by the antenna radiator 200 on the user when the power consumption is small.
Further, when the power of the electromagnetic wave signal radiated by the antenna radiator 200 is greater than a first preset rate, the distance between the antenna radiator 200 and the user is less than a first preset distance, and the ratio of the user to the absorption of the electromagnetic wave signal is greater than a first preset threshold, the controller 400 is further configured to reduce the power radiated by the antenna radiator 200, so that the ratio of the user to the absorption of the electromagnetic wave signal is less than a second preset threshold. Wherein the second preset threshold is smaller than the first preset threshold. In this embodiment, the reduction of the power radiated by the antenna radiator 200 may cause a reduction of the ratio of the absorption of the electromagnetic wave signal by the user, and when the ratio of the absorption of the electromagnetic wave signal by the user is smaller than a second preset threshold, the adverse effect of the electromagnetic wave signal radiated by the antenna radiator 200 on the user is improved compared to when the ratio of the absorption of the electromagnetic wave signal by the user is a first threshold.
Further, the electronic device 10 further includes a frequency deviation corrector 930, and the frequency deviation corrector 930 is configured to correct a frequency deviation caused by a change in the position of the antenna radiator 200 compared to the device body 100. When the position of the antenna radiator 200 is changed compared to the device body 100, the frequency band of the electromagnetic wave signal radiated by the antenna radiator 200 is shifted. Specifically, when the position of the antenna radiator 200 is a first position compared to the device body 100, the frequency band of the electromagnetic wave signal radiated by the antenna radiator 200 is a first frequency band. When the position of the antenna radiator 200 is a second position compared to the device body 100, the frequency band of the electromagnetic wave signal radiated by the antenna radiator 200 is a second frequency band, where the frequency band of the electromagnetic wave signal radiated by the antenna radiator 200 is shifted if the first frequency band is different from the second frequency band. When the position of the antenna radiator 200 is a second position compared to the apparatus body 100, the frequency deviation corrector 930 is configured to correct the electromagnetic wave signal radiated by the antenna radiator 200 from the second frequency band back to the first frequency band. The electronic device 10 may advantageously include a frequency offset corrector 930 to maintain the communication quality of the electronic device 10.
Referring to fig. 5 and 6, fig. 5 is a schematic structural view illustrating a radiation direction of an antenna radiator in an electronic device according to a second embodiment of the present application facing a user; fig. 6 is a schematic structural diagram illustrating a radiation direction of an antenna radiator in an electronic device according to a second embodiment of the present application is away from a user. The electronic device 10 in this embodiment has the same structure as the electronic device 10 in the first embodiment of the present application, except that in this embodiment, when the power of the electromagnetic wave signal radiated by the antenna radiator 200 is greater than a first preset rate, the distance between the antenna radiator 200 and the user is less than a first preset distance, and the ratio of the user to the absorption of the electromagnetic wave signal is greater than a first preset threshold, the control signal is further configured to drive the sliding seat 500 to rotate compared with the device body 100, so that the radiation direction of the antenna radiator 200 deviates from the user.
In this embodiment, since the antenna radiator 200 is disposed on the sliding seat 500, the sliding seat 500 rotates compared to the device body 100, so that the radiation direction of the antenna radiator 200 is changed, and the distance from the antenna radiator 200 to the user is increased. When the power radiated by the antenna radiator 200 is the same, the absorption ratio of the user to the electromagnetic wave signal is reduced when the distance from the antenna radiator 200 to the user is increased. Further, when the direction of the electromagnetic wave signal radiated by the antenna radiator 200 deviates from the user, the ratio of the absorption of the electromagnetic wave signal by the user is reduced, and the adverse effect of the antenna radiator 200 on the physical health of the user is reduced, compared to the case that the direction of the electromagnetic wave signal radiated by the antenna radiator 200 is toward the user.
Referring to fig. 7, fig. 7 is a schematic front structure view of an antenna radiator in an electronic device according to a third embodiment of the present application, the antenna radiator extending out of an accommodating space. The electronic device 10 of the present embodiment has the same structure as the electronic device 10 of the first embodiment of the present application, except that the controller 400 further controls the distance of the antenna radiator 200 from the device body 100 according to the user's wearing equipment.
When the wearable device worn by the user is an electromagnetic wave shielding device, the controller 400 maintains the distance of the antenna radiator 200 to the device body 100.
When the wearable device worn by the user is the electromagnetic wave shielding device, even if the power of the electromagnetic wave signal radiated by the antenna radiator 200 is high, and the distance between the antenna radiator 200 and the user is short, however, since the wearable device worn by the user is the electromagnetic wave shielding device, it is considered that the electromagnetic wave signal radiated by the antenna radiator 200 does not affect the health of the human body, and therefore, the distance between the antenna radiator 200 and the device body 100 does not need to be adjusted.
Specifically, in this embodiment, the electronic device 10 further includes a camera 800, a processor 910, and a memory 920. The camera 800 is used for capturing an image of a user, and the memory 920 stores images of a plurality of electromagnetic wave shielding devices. The processor 910 extracts an image of the wearable device worn by the user from the photographed image of the user and compares the image of the wearable device worn by the user with the images of the plurality of electromagnetic wave shielding devices stored in the memory 920. When the image of the wearable device worn by the user matches any one of the electromagnetic wave shielding devices stored in the memory 920, the wearable device worn by the user is considered to be the electromagnetic wave shielding device.
Further, when the processor 910 compares the image of the wearable device worn by the user with the images of the plurality of electromagnetic wave shielding devices stored in the memory 920, a parallel comparison is employed to save the comparison time. Specifically, the processor 910 compares the image of the user-worn device with the images of the plurality of electromagnetic wave shielding devices stored in the memory 920 at the same time during the same time period, instead of comparing the image of the user-worn device with one of the images of the plurality of electromagnetic wave shielding devices stored in the memory 920 and comparing the next image after the images are not matched.
Further, when the processor 910 compares the image of the device worn by the user with the images of the plurality of electromagnetic wave shielding devices stored in the memory 920, the image of the device worn by the user and the image of the electromagnetic wave shielding devices are first changed from color to a black-and-white image represented by a preset number of gray scales, and then compared to reduce the time spent in the comparison. The preset number may be, but is not limited to, 256. Further, images of the electromagnetic wave shielding device in black and white represented by a preset number of gray levels are previously stored in the memory 920. Furthermore, when the image of the device worn by the user is changed from color to a black-and-white image represented by a preset number of gray scales, the image of the wearable device is divided into a plurality of areas, and then the image in each area is converted into the black-and-white image represented by the preset number of gray scales in parallel in the same time period.
Further, when the processor 910 compares the image of the wearable device worn by the user with the images of the plurality of electromagnetic wave shielding devices stored in the memory 920, and other processing operations are performed, if the electronic device 10 is running other applications, and if the processing space of the processor 910 is larger than the first preset processing space, the processor 910 does not process the running other applications.
When the processor 910 compares an image of a wearable device worn by a user with images of a plurality of electromagnetic wave shielding devices stored in the memory 920, and so on, if the electronic apparatus 10 is running another application, and if the processing space of the processor 910 is smaller than a first preset processing space and larger than a second preset processing space, the processor 910 stops running some functions in the other application, and only some functions in the other application are reserved.
When the processor 910 compares an image of a wearable device worn by a user with images of a plurality of electromagnetic wave shielding devices stored in the memory 920, and so on, if the electronic apparatus 10 is running other applications, and if a processing space of the processor 910 is smaller than a second preset processing space, the processor 910 stops running some of the other applications.
In this embodiment, when the electronic device 10 is running other applications, the running other applications are processed hierarchically according to the storage space of the processor 910 to ensure the requirement of processing space when comparing the image of the wearable device worn by the user with the image of the electromagnetic wave shielding device.
Further, the processor 910 is further configured to extract a first preset number of first features from an image of the wearable device worn by the user, and extract a second preset number of second features from the image of each electromagnetic wave shielding device stored in the memory 920, when the processor 910 compares the image of the wearable device worn by the user with the image of the electromagnetic wave shielding device, the processor 910 compares the first preset number of first features with the second features of the image of the electromagnetic wave shielding device, respectively, and when the number of the first features matching with the second features is greater than a preset number, it is determined that the wearable device worn by the user is the electromagnetic wave shielding device, where the first preset number is less than or equal to the second preset number.
Finally, it should be noted that the above embodiments are only for illustrating the technical solutions of the present application and not for limiting, and although the present application is described in detail with reference to the above preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present application without departing from the spirit and scope of the technical solutions of the present application.
