Description

Technical Field

Background

With the progress of display screen technology, a folding screen mobile terminal that takes into account both portability and large screen characteristics of the mobile terminal is also gradually oriented to the market. The existing folding screen mobile terminal can adjust the display area of a screen by unfolding and folding, and the mobile terminal is generally provided with two screens, and when the mobile terminal is in an unfolded state, the two screens can be combined into one screen; the two screens may be independent two screens when the mobile terminal is in a folded state.

The folding screen mobile terminal generally adopts a plurality of transmitting antennas and receiving antennas respectively used at a transmitting end and a receiving end, so that signals are transmitted and received through the plurality of antennas of the transmitting end and the receiving end, thereby improving the communication quality, and when the folding screen mobile terminal is in an unfolding state, the plurality of antennas distributed on the mobile terminal can well realize a multi-antenna multi-input multi-output (MIMO) function due to larger space distance, so that the multi-input multi-output performance is optimal; however, when the foldable screen terminal is in a folded state, the mimo antennas may form an electromagnetic coupling phenomenon due to a decrease in a spatial distance therebetween, thereby causing a performance degradation of the antennas.

Due to the characteristics of the folding screen mobile terminal, the structure of the mobile terminal has more than two different states, and the different states have larger influence on the antenna, so that the working state of the antenna is judged firstly by a hardware detection means, and then the antenna is matched with different antennas to work, thereby ensuring the optimization of the working performance of the antenna. In some implementations, the folding screen mobile terminal includes a plurality of antenna groups, each antenna group includes two sets of antennas respectively disposed on two screens of the folding screen mobile terminal, and the folding and unfolding of the mobile terminal are detected and judged, and the two sets of antennas are switched back and forth, that is, a mode with a plurality of sets of antenna single parameters is adopted, so that the folding screen mobile phone antenna is unfolded and folded in different states, and the stability of the performance of the antenna is ensured. But it requires multiple sets of antennas to coexist in the structure, requiring more space; moreover, because there are more antennas, the requirement for the clearance area is more, which affects the layout and appearance of the motherboard of the whole device.

The foregoing description is provided for general background information and is not admitted to be prior art.

Based on the above mobile terminal hardware structure and communication network system, various embodiments of the present application are provided.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a foldable mobile terminal according to an embodiment of the present application. The foldable mobile terminal 100 includes a first screen module 11, a second screen module 12 and a rotating shaft 13, the first screen module 11 and the second screen module 12 are rotatably connected through the rotating shaft 13 to realize the relative folding of the first screen module 11 and the second screen module 12, and optionally, the first screen module 11 and the second screen module 12 both adopt flexible screens.

The foldable mobile terminal 100 further includes an antenna module, which is disposed on any one of the first screen module 11 and the second screen module 12, and the antenna module includes an antenna 21 and a matching circuit, and the matching circuit is configured to adjust antenna tuning parameters according to different working state information of the foldable mobile terminal 100, so as to adjust impedance corresponding to the antenna 21. Alternatively, the operation state of the foldable mobile terminal 100 includes a folded state and/or an unfolded state.

The first screen module 11 and the second screen module 12 can rotate around the rotation shaft 13 to make the foldable mobile terminal 100 in a folded state or an unfolded state. When the foldable mobile terminal 100 is in a folded state, the first screen module 11 and the second screen module 12 may be disposed facing each other or disposed away from each other; when the foldable mobile terminal 100 is in the unfolded state, the first screen module 11 and the second screen module 12 are oriented in the same direction, and the first screen module 11 and the second screen module 12 are unfolded to form a complete display screen.

Compared with the prior art that the single-parameter mode of a plurality of groups of antennas 21 is used, the two groups of antennas 21 are switched back and forth to realize that the performance stability of the antenna 21 is ensured when the terminal antenna 21 of the folding screen is folded and unfolded in different states, the foldable mobile terminal 100 of the application is arranged on any screen module through one group of antennas 21, the matching circuit matches different antenna tuning parameters to adjust the impedance of the antenna 21 according to different working state information of the foldable mobile terminal 100, namely, the single-parameter mode of the single antenna 21 replaces the single-parameter mode of the plurality of groups of antennas 21 in the prior art, the matching circuit is switched among different parameters to match different antenna tuning parameters to realize the performance of the antenna 21, thereby realizing the sharing of the antennas 21 in the folded and unfolded states on the premise of ensuring the performance of the antenna 21, reducing the number of the antennas 21 and reducing the number of occupied screen modules, the space of the antenna 21 is saved, and the influence of the antenna 21 clearance area on the mainboard ornament is reduced.

Since the foldable mobile terminal 100 is folded and unfolded, the user's usage requirements are different, for example, the folding is more focused on the performance of cellular communication or mobile communication, and the unfolding is more focused on the experience of audio and video. And the antenna 21 defaults to be the working state, when the foldable mobile terminal 100 is in the folded state, the resonance with the antenna 21 in the unfolded state has difference, for better communication experience, a matching circuit is needed to correspond to the matching of different states, so the antenna tuning parameter corresponds to the two states of folding and unfolding, which state the foldable mobile terminal 100 is in is judged according to the detection device, and the system selects the corresponding state to tune the impedance of the antenna 21.

One antenna 21 is matched with multiple groups of parameters, and different antenna tuning parameters are matched through a matching circuit to work according to the detected working state, so that the optimization of the performance of the antenna 21 is ensured. The matching circuit comprises a first variable impedance circuit 22 and/or a second variable impedance circuit 23, i.e. the first variable impedance circuit 22 and the second variable impedance circuit 23 may be applied separately or in combination to enable tuning of a wider range of operating frequency bands of the antenna 21. The impedance of the antenna 21 is tuned by the first variable impedance circuit 22 and/or the second variable impedance circuit 23 according to different operation state information of the foldable mobile terminal 100 to ensure the performance of the antenna 21.
