In the communication device provided by the embodiment of the present application, the first preset antenna and the second preset antenna are set from multiple Wi-Fi antennas in advance, wherein the first preset antenna is used for the communication device to perform Wi-Fi communication. The second preset antenna is used for communication between the external device and the communication device. And the two output terminals of the switch circuit are electrically connected with the first preset antenna and the second preset antenna, the first input terminal of the switch circuit is electrically connected with the signal terminal of the Wi-Fi chip, and the second input terminal of the switch circuit is electrically connected with The signal terminal of the peripheral chip is electrically connected, the output terminal of the control terminal of the switch circuit is electrically connected, and the output terminal of the peripheral chip is electrically connected with the input terminal of the control circuit. Based on the foregoing electrical connection relationship, when the peripheral chip and the external device are successfully matched, the peripheral chip may send a matching success message to the control circuit. When receiving the matching success message, the control circuit can control the Wi-Fi chip to be electrically connected to the first preset antenna and control the peripheral chip to be electrically connected to the second preset antenna through the switch circuit. Thus, the Wi-Fi chip can control the communication device to perform Wi-Fi communication through the first preset antenna, and the peripheral chip can control the external device to communicate with the communication device through the second preset antenna. In the embodiments of this application, not only can the normal Wi-Fi communication of the communication device be ensured, but also the idle Wi-Fi antenna can be reasonably used to realize the communication between the communication device and the external device, and the overall layout of the antenna can be reduced without adding a new Wi-Fi antenna. The difficulty of this increases the utilization rate of Wi-Fi antennas, increases the communication rate between external devices and communication devices, and satisfies various low-latency scenarios, allowing users to operate flexibly and to facilitate the use of external devices.

Exemplarily, on the basis of the embodiment shown in FIG. 1, the communication device 1 of the embodiment of the present application still has an idle Wi-Fi antenna 11 under the premise of ensuring normal Wi-Fi communication, so the peripheral chip 14 In addition to using traditional Bluetooth technology, an idle Wi-Fi antenna 11 can also be used to search for external devices. In the following, with reference to FIG. 2, the implementation process of the peripheral chip 14 using the Wi-Fi antenna 11 to search for external devices in the embodiment of the present application will be described in detail.

Those skilled in the art can understand that no matter in different application scenarios, the communication device 1 usually selects a Wi-Fi antenna 11 with better communication quality for Wi-Fi communication to ensure the quality of Wi-Fi communication. In the embodiment of the present application, the Wi-Fi chip 13 can determine the communication quality of each Wi-Fi antenna 11 and obtain the determination result. The judgment result is that the communication quality of the first target antenna is better than the communication quality of the second target antenna. Thus, the first target antenna can be used for Wi-Fi communication of the communication device 1, and the second target antenna can be used for the peripheral chip 14 to search for external devices, so that the second target antenna can be used as a dedicated antenna for the peripheral chip 14 to search for external devices. .

In the embodiment of the present application, in the same application scenario, the first target antenna and the second target antenna are different. In different application scenarios, the first target antenna and the second target antenna may be the same or different. Wherein, the number of the first target antenna may be multiple to form a MIMO antenna to work, or it may be one, which is not limited in the embodiment of the present application. The number of the second target antenna may be one or multiple to form a MIMO antenna, which is not limited in this embodiment of the application.

Among them, the embodiment of the present application does not limit the basis for determining the communication quality of each Wi-Fi antenna 11. For example, the Wi-Fi chip 13 may determine the received signal strength indication (RSSI) of each Wi-Fi antenna 11 according to the collected signals of each Wi-Fi antenna 11, and according to each Wi-Fi antenna 11 The RSSI of 11 determines the communication quality of each Wi-Fi antenna 11.

In the embodiment of the present application, each output terminal of the switch circuit 15 is electrically connected to a Wi-Fi antenna 11, that is, the first target antenna and the second target antenna are electrically connected to the output side of the switch circuit 15. And the first input terminal of the switch circuit 15 is electrically connected with the signal terminal of the Wi-Fi chip 13, and the second input terminal of the switch circuit 15 is electrically connected with the signal terminal of the peripheral chip 14.

In this way, the output terminal of the control circuit 12 is electrically connected to the control terminal of the switch circuit 15, and can control the conduction or disconnection of the path between any input terminal and any output terminal of the switch circuit 15 to adjust Wi-Fi. Whether the chip 13 and the peripheral chip 14 are electrically connected to any Wi-Fi antenna 11 respectively, that is, it is adjusted whether the Wi-Fi chip 13 and the peripheral chip 14 are electrically connected to the first target antenna and the second target antenna, respectively.

Based on the foregoing description, as shown in FIG. 2, the output terminal of the Wi-Fi chip 13 can be electrically connected to the second input terminal of the control circuit 12 to send the judgment result to the control circuit 12. Wherein, the judgment result can be expressed in various forms including, but not limited to, numbers, secondary numerical values, letters, and words. Therefore, when the control circuit 12 receives the judgment result, it can learn that the communication quality of the first target antenna is better than that of the second target antenna, and can realize Wi-Fi communication of the communication device 1 through the first target antenna. And the process of searching for external devices by the peripheral chip 14 is realized through the second target antenna.

Furthermore, the control circuit 12 can execute the following operations in parallel.

On the one hand, the control circuit 12 can control Wi-Fi by turning on the path between the input terminal of the switch circuit 15 electrically connected to the Wi-Fi chip 13 and the output terminal of the switch circuit 15 electrically connected to the first target antenna. The chip 13 is electrically connected with the first target antenna to realize Wi-Fi communication of the communication device 1.

Since the Wi-Fi chip 13 is electrically connected to the first target antenna, the Wi-Fi chip 13 can control the communication device 1 to perform Wi-Fi communication through the first target antenna, such as sending and receiving Wi-Fi required by the communication device 1 Signal to ensure that the communication device 1 can communicate with Wi-Fi normally.

On the other hand, the control circuit 12 can control the peripheral chip by turning on the path between the input terminal of the switch circuit 15 electrically connected to the peripheral chip 14 and the output terminal of the switch circuit 15 electrically connected to the second target antenna. 14 is electrically connected to the second target antenna to realize the function of the peripheral chip 14 to search for external devices.

Since the peripheral chip 14 is electrically connected to the second target antenna, the peripheral chip 14 can control the peripheral chip 14 to search for external devices through the second target antenna. For example, when the external device is started and placed within a certain range from the peripheral chip 14, the peripheral chip 14 can search for the external device through the second target antenna. Furthermore, the peripheral chip 14 can be matched with the searched external device, such as checking whether the external device is an authorized device, judging whether the operating environment of the external device is safe, and so on. Generally, if the external device and the peripheral chip 14 have not been matched, the peripheral chip 14 can be matched with the searched external device. If the external device and the peripheral chip 14 have been successfully matched, the peripheral chip 14 can directly match the searched external device successfully.

The communication device provided by the embodiment of the present application is electrically connected to the first target antenna and the second target antenna through the two output terminals of the switch circuit, the first input terminal of the switch circuit is electrically connected to the signal terminal of the Wi-Fi chip, and the switch The second input terminal of the circuit is electrically connected with the signal terminal of the peripheral chip, the output terminal of the Wi-Fi chip is electrically connected with the input terminal of the control circuit, and the output terminal of the control circuit is electrically connected with the control terminal of the switch circuit. Based on the above electrical connection relationship, the Wi-Fi chip can determine the communication quality of multiple Wi-Fi antennas, and send the determination result to the control circuit, where the determination result is that the communication quality of the first target antenna is better than that of the second target antenna Communication quality. When the control circuit receives the judgment result, it can determine that the first target antenna is used for the communication device for Wi-Fi communication, and the second target antenna is used for the peripheral chip to search for external devices. The switch circuit can control the Wi-Fi chip and the second target antenna. A target antenna is electrically connected and the control external device chip is electrically connected with the second target antenna. Thus, the Wi-Fi chip can control the communication device to perform Wi-Fi communication through the first target antenna, and the peripheral chip can control the peripheral chip to search for the external device through the second target antenna. In the embodiments of the present application, not only can the normal Wi-Fi communication of the communication device be ensured, but also idle Wi-Fi antennas can be used rationally to realize the process of searching for external devices by the peripheral chip, which improves the utilization rate of the Wi-Fi antenna and makes Wi-Fi -Fi antennas can be optimized for multiplexing. While reducing the number of Wi-Fi antennas, it effectively ensures the performance of Wi-Fi antennas.

In addition, when the communication device 1 performs Wi-Fi communication through the first target antenna, and the peripheral chip 14 searches for and successfully matches the external device through the second target antenna, the peripheral chip 14 may send a matching success message to the control circuit 12, so that The control circuit 12 learns that there is an external device that needs to communicate with the communication device 1. Therefore, the control circuit 12 can determine that it is necessary to control the Wi-Fi chip 13 to be electrically connected to the first preset antenna, and to control the peripheral chip 14 to be electrically connected to the second preset antenna.

Since whether the Wi-Fi chip 13 is electrically connected to the first preset antenna and whether the peripheral chip 14 is electrically connected to the second preset antenna depends on whether the path between the input terminal and the output terminal of the switch circuit 15 is turned on or off. Therefore, the control circuit 12 can set the Wi-Fi chip 13 to be electrically connected to the first preset antenna through the switch circuit 15 in advance, and the peripheral chip 14 to be electrically connected to the second preset antenna through the switch circuit 15 to be preset status.

In order to realize the above process, the control circuit 12 may adjust the current state of the switch circuit 15 to a preset state. At this time, the Wi-Fi chip 13 has been electrically connected to the first target antenna through the switch circuit 15, and the peripheral chip 14 has been electrically connected to the second target antenna through the switch circuit 15. Therefore, the control circuit 12 can obtain the switch circuit 15 The current state, that is, the current state is a state where the Wi-Fi chip 13 is electrically connected to the first target antenna through the switch circuit 15 and the peripheral chip 14 is electrically connected to the second target antenna through the switch circuit 15. Therefore, the control circuit 12 can determine whether the current state of the switch circuit 15 is a preset state, and adjust the electrical connection relationship between the Wi-Fi chip 13 and the peripheral chip 14 and the Wi-Fi antenna 11, so that the Wi-Fi chip 13 can be connected to the Wi-Fi antenna 11. A preset antenna is electrically connected and the peripheral chip 14 is electrically connected with a second preset antenna.

When the control circuit 12 determines that the current state of the switch circuit 15 is the preset state, the control circuit 12 can lock the current state of the switch circuit 15 so that the Wi-Fi chip 13 can control the communication device 1 to pass through the first target antenna (ie, the first preset state). Set an antenna) for Wi-Fi communication, and the peripheral chip 14 controls the external device to communicate with the communication device 1 through the second target antenna (ie, the second preset antenna).

When the control circuit 12 determines that the current state of the switch circuit 15 is not the preset state, the control circuit 12 can update the current state of the switch circuit 15 to the preset state, so that the Wi-Fi chip 13 can switch to the first state through the switch circuit 15 A preset antenna is electrically connected to realize the process of the communication device 1 performing Wi-Fi communication through the first preset antenna, and the peripheral chip 14 can be switched to be electrically connected with the second preset antenna through the switch circuit 15, so that the external device can pass through The communication process between the second preset antenna and the communication device 1.

Optionally, after the control circuit 12 updates the current state of the switch circuit 15 to a preset state, it can also lock the current state of the switch circuit 15, that is, the Wi-Fi chip 13 is electrically connected to the first preset antenna and the peripheral chip 14 The state of being electrically connected to the second preset antenna.

In the embodiment of the present application, after the communication device performs Wi-Fi communication through the first target antenna, and the peripheral chip searches for the external device through the second target Wi-Fi antenna, when the peripheral chip matches the external device successfully, the control circuit It can be judged whether the current state of the switch circuit is the preset state. If so, the control circuit can determine that the first target antenna is the first preset antenna, and the second target antenna is the second preset antenna, and the current state of the switch circuit can be locked. If not, the control circuit can adjust the current state of the switch circuit to the preset state, so that the Wi-Fi chip is electrically connected to the first preset antenna and the peripheral chip is electrically connected to the second preset antenna. Thus, the communication device can perform Wi-Fi communication through the first preset antenna, and the external device can communicate with the communication device through the second preset antenna.

Exemplarily, in the embodiment of the present application, the first preset antenna and the second preset antenna may be located at any positions of the communication device 1, and are usually set based on actual experience. Hereinafter, the positions of the first preset antenna and the second preset antenna will be described with reference to FIGS. 3 to 4. For ease of description, take the multiple Wi-Fi antennas 11 including a first Wi-Fi antenna and a second Wi-Fi antenna as an example for illustration.

Those skilled in the art can understand that when the user holds the short side of the communication device 1 with both hands, the communication device 1 is usually in a landscape state, as shown in FIG. 3. When the user holds the long sides of the communication device 1 with both hands, the communication device 1 is usually in a vertical screen state, as shown in FIG. 4. It should be noted that the above method is only an optional method for defining the communication device 1 in the vertical screen state and the horizontal screen state, and the embodiment of the present application is not limited to this method.

As shown in FIG. 3, when the communication device 1 is in the landscape state, it is easier for the user to hold the short side of the communication device 1 and close to the location area of the bottom side of the communication device 1, and it is not easy for the user to hold the other location areas of the communication device 1. As shown in FIG. 4, when the communication device 1 is in the vertical screen state, it is easier for the user to hold the long side of the communication device 1 and the location area close to the bottom side of the communication device 1, and it is not easy to hold the other location areas of the communication device 1 by hand.

Based on the above description, combined with Figures 3 and 4, in order to be applicable to different scenarios in which the communication device 1 is in the vertical screen state and the horizontal screen state, the embodiment of the present application may use the second Wi-Fi antenna (in Figure 3 and Figure 4 with A second Wi-Fi antenna is taken as an example for illustration) is set in the upper half of the area when the communication device 1 is in the horizontal screen state to prevent the second Wi-Fi antenna from being blocked when the communication device 1 is in the horizontal screen state. In the embodiment of the present application, the first Wi-Fi antenna (a first Wi-Fi antenna is taken as an example in FIG. 3 and FIG. 4 for illustration) is located in the upper half of the area where the communication device 1 is in the vertical screen state, Prevent the first Wi-Fi antenna from being blocked when the communication device 1 is in the vertical screen state.

Among them, the embodiment of the present application does not limit the specific positions and numbers of the first Wi-Fi antenna and the second Wi-Fi antenna. For example, when the communication device 1 is in a landscape state, the second Wi-Fi antenna may be located at the center of the top of the communication device 1. When the communication device 1 is in the vertical screen state, the first Wi-Fi antenna may be located at the center of the top of the communication device 1.

In addition, since the communication device 1 is close to the support structure such as the desktop when it is in the horizontal screen state, the performance of the first Wi-Fi antenna is reduced. Therefore, in the embodiment of the present application, the first Wi-Fi antenna is set in the vertical position of the communication device 1. On the basis of the upper half area in the screen state, it is also necessary to set the first Wi-Fi antenna to have a preset distance from the bottom edge of the communication device 1 in the horizontal screen state. Among them, the preset distance can be combined with actual experience to perform equipment, which is not limited in the embodiment of the present application.

As shown in FIG. 3, when the communication device 1 is in the landscape state, compared with the second Wi-Fi antenna, the first Wi-Fi antenna is easier to be held by the hand and its performance decreases. Therefore, the embodiment of the present application may The second Wi-Fi antenna is set as the first preset antenna, and the first Wi-Fi antenna is set as the second preset antenna.

As shown in FIG. 4, when the communication device 1 is in the vertical screen state, compared with the first Wi-Fi antenna, the second Wi-Fi antenna is easier to be held by the hand and its performance decreases. Therefore, the embodiment of the present application may The first Wi-Fi antenna is set as the first preset antenna, and the second Wi-Fi antenna is set as the second preset antenna.

On the basis of the above-mentioned embodiments shown in Figs. 3 to 4, as shown in Fig. 5 (for ease of description, Fig. 5 only shows the embodiment shown in Fig. 3 as a basis), the communication device 1 may further include: a third Wi-Fi antenna (in Figure 5, a third Wi-Fi antenna is used as an example for illustration). Wherein, the other signal end of the Wi-Fi chip 13 is electrically connected to the third Wi-Fi antenna.

Since the third Wi-Fi antenna is located in the upper half area when the communication device 1 is in the vertical screen state, and is located in the upper half area when the communication device 1 is in the horizontal screen state, no matter if the communication device 1 is in the horizontal screen state or the vertical screen state, In the screen state, the third Wi-Fi antenna is not easy to be held by hand.

Based on the above description, the third Wi-Fi antenna can be used for Wi-Fi communication of the communication device 1 to ensure the Wi-Fi communication of the communication device 1. When the communication device 1 is in the horizontal screen state, the second Wi-Fi antenna and the third Wi-Fi antenna may jointly form a MIMO antenna to realize Wi-Fi communication of the communication device 1. When the communication device 1 is in the vertical screen state, the first Wi-Fi antenna and the third Wi-Fi antenna may jointly form a MIMO antenna to realize Wi-Fi communication of the communication device 1.

Among them, the embodiment of the present application does not limit the specific position and number of the third Wi-Fi antenna. For example, when the communication device 1 is in a landscape state, the third Wi-Fi antenna may be located at the center of the top of the communication device 1. When the communication device 1 is in the vertical screen state, the third Wi-Fi antenna may be located at the center of the top of the communication device 1.

Continuing to combine with FIG. 5, the communication device 1 may further include: a peripheral charging interface 16 (the peripheral charging interface 16 is illustrated with multiple circles in FIG. 5). Among them, the peripheral charging interface 16 is located in the lower half of the area when the communication device 1 is in the first state, and the peripheral charging interface 16 is close to the bottom of the lower area to facilitate the communication device 1 to charge external devices.

Among them, the embodiment of the present application does not limit the specific location, number, and type of the external charging interface 16. In addition, the first state may be a horizontal screen state or a vertical screen state, which is not limited in the embodiment of the present application. For example, when the communication device 1 is in a horizontal screen state, the peripheral charging interface 16 may be located at the center of the bottom edge of the communication device 1. When the communication device 1 is in the vertical screen state, the peripheral charging interface 16 may be located at the center of the bottom side of the communication device 1.

For example, if the communication device 1 is a tablet, the tablet is put on the tablet case, and the external device is placed on the tablet case. At this time, the tablet can charge the external device through the external device charging interface 16 through the tablet case. It should be noted that the above charging method is only an exemplary method in which the communication device 1 charges an external device through the external charging interface 16 and the embodiment of the present application is not limited to the above charging method.

Exemplarily, an embodiment of the present application also provides an antenna switching method. The antenna switching method may be implemented by the communication device in the above-mentioned embodiments shown in FIG. 1 to FIG. 5 through software and/or hardware. A first preset antenna and a second preset antenna are set in two Wi-Fi antennas, where the first preset antenna is used for Wi-Fi communication by the communication device, and the second preset antenna is used between the external device and the communication device Based on the electrical connection relationship of various components in the communication device, not only can the normal Wi-Fi communication of the communication device be realized through the first preset antenna, but also the idle Wi-Fi antenna (ie the second preset antenna) Realize the communication between the communication device and the external device, improve the utilization rate of the Wi-Fi antenna, increase the communication rate between the external device and the communication device, meet various scenarios with low operation delay, and ensure the flexibility of the user Operation and easy to use.

Exemplarily, the antenna switching method of the embodiment of the present application can also determine that the communication quality of the first target antenna is better than the communication quality of the second target antenna, based on the electrical connection relationship of each component in the communication device, not only through the first A target antenna realizes the normal Wi-Fi communication of the communication device, and the idle Wi-Fi (that is, the second target antenna) can also be used to realize the process of searching for external devices by the peripheral chip, which improves the utilization rate of the Wi-Fi antenna.

Fig. 7 is a flowchart of an exemplary antenna switching method provided by an embodiment of the application. As shown in FIG. 7, the antenna switching method of the embodiment of the present application may include:

S201. The Wi-Fi chip judges the communication quality of multiple Wi-Fi antennas.

S202. The Wi-Fi chip sends a judgment result to the control circuit, where the judgment result is that the communication quality of the first target antenna is better than the communication quality of the second target antenna, and the first target antenna is used for Wi-Fi communication of the communication device. The second target antenna is used for the peripheral chip to search for external devices.

S203. When receiving the judgment result, the control circuit controls the Wi-Fi chip to switch to be electrically connected to the first target antenna through the switch circuit, and controls the peripheral chip to switch to be electrically connected to the second target antenna through the switch circuit.

S204. The Wi-Fi chip controls the communication device to perform Wi-Fi communication through the first target antenna.

However, since at the end of the steps shown in Figure 7, the Wi-Fi chip is electrically connected to the first target antenna, and the peripheral chip is electrically connected to the second target antenna, it can be seen that the current state of the switch circuit is that the Wi-Fi chip passes through the switch circuit. It is electrically connected to the first target antenna, and the peripheral chip is electrically connected to the second target antenna through the switch circuit. However, in the steps shown in FIG. 6, the Wi-Fi chip needs to be electrically connected to the first preset antenna, and the peripheral chip needs to be electrically connected to the second preset antenna. For convenience of description, the preset state of the switch circuit can be set in advance to a state where the Wi-Fi chip is electrically connected to the first preset antenna through the switch circuit, and the peripheral chip is electrically connected to the second preset antenna through the switch circuit.

Based on the foregoing description, before the communication device executes the steps shown in FIG. 6, optionally, the control circuit may determine whether the current state of the switch circuit is a preset state.

When the control circuit determines that the current state of the switch circuit is the preset state, the control circuit can lock the current state of the switch circuit so that the Wi-Fi chip controls the communication device to perform Wi-Fi through the first target antenna (ie, the first preset antenna) The communication and peripheral chip controls the external device to communicate with the communication device through the second target antenna (ie, the second preset antenna).
