Background
The current intelligent mobile terminals (mobile phones, tablets and notebook computers) are very popular and are an indispensable part of the work and life of people. The mobile terminal can move around due to its wireless communication function.
As is well known, the basis of wireless communication is electromagnetic wave communication. Electromagnetic waves inevitably cause certain radiation to human beings due to certain energy and frequency, and the radiation is defined as SAR (specific Absorption rate) which means specific Absorption rate of electromagnetic waves. Generally SAR is proportional to electromagnetic wave energy and frequency. Radiation is inevitable as long as wireless products are used. The different radiation intensities are also very different in harming the human body. Therefore, scientific organizations have studied how much radiation intensity will have an impact on human health, and standardized definitions are made in the industry, particularly by mobile terminal certification organizations.
Since the frequency spectrum resource of commercial wireless communication is fixed, it is impossible to reduce the Sar by reducing the frequency of electromagnetic waves. The SAR reduction requirements are typically achieved in a reduced power manner. In practice, however, the power transmitted by the wireless module is proportional to the performance of the communication, i.e., the power reduction inevitably causes performance degradation.

Detailed Description
In order to explain technical contents and structural features of the present invention in detail, the following description is made with reference to the embodiments and the accompanying drawings.
Referring to fig. 1 to 5, the present invention discloses a mobile terminal, including:
a housing 1, the housing 1 having a clearance area 2 formed thereon, the clearance area 2 being divided into a plurality of antenna positions 20;
an antenna 3, wherein the antenna 3 is movably arranged in the clearance area 2;
a plurality of feed points, the feed points being disposed in correspondence with the antenna locations 20;
a sensor 4, the sensor 4 being disposed near the clearance area 2, the sensor 4 being configured to sense contact and/or approach of a human body and output a corresponding position signal;
a drive mechanism 5, the drive mechanism 5 configured to drive the antenna 3 to move between a plurality of antenna positions 20 of the clearance area 2;
a processor 6, the processor 6 being configured to perform:
acquiring a position signal corresponding to the human body from the sensor 4;
calculating an antenna position 20 with minimum radiation to the human body according to the position signal;
if the antenna 3 is not at the antenna position 20 where the radiation to the human body is minimum, the control driving mechanism 5 drives the antenna 3 to move to the antenna position 20 where the radiation to the human body is minimum and makes the antenna 3 communicate with the corresponding feeding point (fig. 3 provides an example of the movement of the antenna 3 due to the contact of the human hand H). If the antenna 3 is now in a position where the radiation to the human body is minimal, the processor 6 does not need to perform a corresponding control action.
When a human body contacts the corresponding position near the antenna 3, the antenna 3 can move to the antenna position 20 with minimum radiation to the human body, so that the radiation to the human body can be reduced, technical means for reducing power is not needed, and the communication performance of the mobile terminal cannot be influenced. In addition, the present invention can ensure feeding when the antenna 3 is moved to each antenna position 20 by providing a plurality of feeding points corresponding to each antenna position 20.
It should be noted that the housing 1 is not limited to be a structure that constitutes the whole frame of the mobile terminal, and the clearance area 2 formed on the housing 1 does not mean that the clearance area 2 is formed by the housing 1.
Generally, the intensity of radiation to the human body is inversely proportional to the distance of the antenna 3, and the radiation decreases as the distance increases. Thus, the location of least radiation to the body is generally the furthest location from the body.
In some embodiments, the clearance area 2 is formed at an edge of the housing 1, and the plurality of antenna locations 20 are distributed along the edge of the housing 1. Specifically, the mobile terminal includes a screen 7, and the headroom regions 2 are respectively located outside the screen 7. In the specific example of the present invention, the upper left corner and the upper right corner of the housing 1 respectively form a right-angled clearance area 2, the two clearance areas 2 are respectively provided with the movable antennas 3, and the two clearance areas 2 are respectively divided into eight antenna positions 20.
In some embodiments, the number of sensors 4 is plural, and arranged thereon along the rim of the housing 1. Preferably, the sensing ranges of the plurality of sensors 4 arranged along the extending direction of the frame at least correspond to the clearance area 2.
For achieving a better sensing effect, the sensor 4 may be a pressure sensor, a proximity sensor, or the like, which is not limited herein.
As for the drive mechanism 5, various means that can be conceived by those skilled in the art can be adopted, and not limited herein. For example, the antenna 3 may be driven to move by a mode of combining a motor with a transmission mechanism, a guide rail or the like may be provided to facilitate the movement of the antenna 3, and the antenna 3 may be mounted on the guide rail through an antenna bracket.
Referring to fig. 6, in some embodiments, the mobile terminal further includes an rf transceiver 8 and a power divider 9, where the power divider 9 is configured to divide the rf signal generated by the rf transceiver 8 into multiple paths of signals and transmit the multiple paths of signals to multiple feeding points respectively. Through the arrangement of the power divider 9, the radio frequency signals generated by the radio frequency transceiver 8 can be divided into multiple paths of signals and transmitted to a plurality of feeding points respectively, so that feeding signals can be provided for the plurality of feeding points conveniently. Of course, the power divider 9 may not be used, for example, the rf transceiver 8 may directly provide multiple rf signals to multiple feeding points.
Preferably, the mobile terminal includes a plurality of dome switches 10, the dome switches 10 are respectively disposed corresponding to the antenna positions 20, and the dome switches 10 form a plurality of feeding points.
Referring to fig. 5 and 6, in a normal state, the dome switches 10 are all in an off state except for one corresponding to the antenna 3; the processor 6 is further configured to perform: when the antenna 3 moves to the antenna position 20 with the minimum radiation to the human body, the corresponding elastic sheet switch 10 is controlled to be switched on, specifically, the corresponding elastic sheet switch 10 is controlled to be switched on through the power divider 9. Because the dome switches 10 are all in the off state except the corresponding antenna 3, the influence of the dome switches 10 on the moving path on the antenna 3 can be avoided when the antenna 3 moves, and the reliability of the movement and performance of the antenna 3 is ensured.
In summary, when the mobile terminal of the present invention contacts or approaches the antenna 3, the sensor 4 can sense the contact or approach of the human body and output a corresponding position signal, and the processor 6 can calculate the antenna position 20 with the minimum radiation to the human body according to the position signal and can control the driving mechanism 5 to move the antenna 3 to the antenna position 20 with the minimum radiation to the human body and communicate the antenna 3 with the corresponding feeding point. The antenna 3 is moved to the antenna position 20 with minimum radiation to the human body, so that the aim of reducing the radiation to the human body is fulfilled, a technical means for reducing power is not needed, and the communication performance of the mobile terminal is not influenced. In addition, the present invention can ensure feeding when the antenna 3 is moved to each antenna position 20 by providing a plurality of feeding points corresponding to each antenna position 20.
The above disclosure is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, so that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
