And the two output ends of the switch circuit are electrically connected to the first preset antenna and the second preset antenna respectively, the first input end of the switch circuit is electrically connected to the signal end of the Wi-Fi chip, and the second input end of the switch circuit is electrically connected to the Wi-Fi chip. 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 to the input terminal of the control circuit. Based on the above electrical connection relationship, when the peripheral chip and the external device are successfully matched, the peripheral chip can 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 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 embodiment of the present application, not only the normal Wi-Fi communication of the communication device can 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 is reduced without adding a Wi-Fi antenna. It improves the utilization rate of Wi-Fi antennas, improves the communication rate between external devices and communication devices, meets various low-latency scenarios, enables users to operate flexibly, and facilitates users to use external devices.

Exemplarily, on the basis of the above-mentioned embodiment shown in FIG. 1 , on the premise of ensuring normal Wi-Fi communication, the communication device 1 of the embodiment of the present application still has an idle Wi-Fi antenna 11 , so the peripheral chip 14 In addition to using the traditional Bluetooth technology, it is also possible to use the idle Wi-Fi antenna 11 to search for external devices. Below, 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 the 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 judge the communication quality of each Wi-Fi antenna 11 to obtain the judgment 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. Therefore, 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. The number of the first target antennas may be multiple to form a MIMO antenna to work, or there may be one, which is not limited in this embodiment of the present application. The number of the second target antenna may be one or multiple, so as to form a MIMO antenna to work, which is also not limited in this embodiment of the present application.

Wherein, the embodiments of the present application do not limit the basis for determining whether the communication quality of each Wi-Fi antenna 11 is good or bad. 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 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 The RSSI of 11 is used to judge the communication quality of each Wi-Fi antenna 11 .

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

In this way, the output terminal of the control circuit 12 can be electrically connected to the control terminal of the switch circuit 15 to control the conduction or disconnection of the path between any input terminal and any output terminal of the switch circuit 15 to adjust the Wi-Fi Whether the chip 13 and the peripheral chip 14 are electrically connected to any one of the Wi-Fi antennas 11 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 above description, as shown in FIG. 2 , the output terminal of the Wi-Fi chip 13 can send the judgment result to the control circuit 12 through electrical connection with the second input terminal of the control circuit 12 . Wherein, the judgment result may be expressed in various forms including but not limited to numbers, secondary numerical values, letters, and characters. Therefore, when the control circuit 12 receives the judgment result, it can know that the communication quality of the first target antenna is better than that of the second target antenna, and can realize the 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 implemented through the second target antenna.

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

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

Since the Wi-Fi chip 13 is electrically connected with 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 that is electrically connected to the peripheral chip 14 and the output terminal of the switch circuit 15 that is electrically connected to the second target antenna. 14 is electrically connected to the second target antenna, so as 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 activated 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 match the searched external device, such as checking whether the external device is an authorized device, and judging whether the operating environment of the external device is safe or not. In general, 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 are successfully matched, the peripheral chip 14 can be directly matched with the searched external device.

In the communication device provided by the embodiment of the present application, the two output ends of the switch circuit are respectively electrically connected to the first target antenna and the second target antenna, the first input end of the switch circuit is electrically connected to the signal end of the Wi-Fi chip, and the switch circuit is electrically connected to the signal end of the Wi-Fi chip. The second input end of the circuit is electrically connected to the signal end of the peripheral chip, the output end of the Wi-Fi chip is electrically connected to the input end of the control circuit, and the output end of the control circuit is electrically connected to the control end of the switch circuit. Based on the above electrical connection relationship, the Wi-Fi chip can judge the communication quality of multiple Wi-Fi antennas, and send a judgment result to the control circuit, wherein the judgment 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 to perform Wi-Fi communication, and the second target antenna is used for the peripheral chip to search for external devices, and the switch circuit can control the Wi-Fi chip and the first target antenna. A target antenna is electrically connected and the control peripheral 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 external devices through the second target antenna. In the embodiment of the present application, not only the normal Wi-Fi communication of the communication device can be ensured, but also the idle Wi-Fi antenna can be reasonably used 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 the Wi-Fi antenna more efficient. -Fi antennas are optimized for reuse, which effectively ensures the performance of Wi-Fi antennas while reducing the number 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 can send a matching success message to the control circuit 12, so that The control circuit 12 knows that there is an external device that needs to communicate with the communication device 1 . Therefore, the control circuit 12 can determine that the Wi-Fi chip 13 needs to be controlled to be electrically connected to the first preset antenna, and the peripheral chip 14 needs to be controlled to be electrically connected to the second preset antenna.

Whether the Wi-Fi chip 13 is electrically connected to the first predetermined antenna and whether the peripheral chip 14 is electrically connected to the second predetermined antenna depends on whether the path between the input end and the output end 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 state of the peripheral chip 14 to be electrically connected to the second preset antenna through the switch circuit 15 is preset state.

In order to realize the above process, the control circuit 12 can 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 information of the switch circuit 15 . The current state, that is, the current state is that 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 first A predetermined antenna is electrically connected and the peripheral chip 14 is electrically connected to the second predetermined 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 the first target antenna (ie the first preset state) set antenna) to perform 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 be switched to the same state as the first state through the switch circuit 15 A preset antenna is electrically connected to realize the process that the communication device 1 performs Wi-Fi communication through the first preset antenna, and the peripheral chip 14 can be switched to be electrically connected to the second preset antenna through the switch circuit 15, so that the external device can pass The communication process between the second preset antenna and the communication device 1 .

Optionally, after updating the current state of the switch circuit 15 to a preset state, the control circuit 12 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 is connected. 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 and the external device are successfully matched, the control circuit It can be determined whether the current state of the switch circuit is a 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 a 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 this embodiment of the present application, the first preset antenna and the second preset antenna may be located at any position of the communication device 1, and are usually set based on actual experience. The positions of the first preset antenna and the second preset antenna will be described below with reference to FIGS. 3 to 4 . For the convenience of description, the multiple Wi-Fi antennas 11 including the first Wi-Fi antenna and the second Wi-Fi antenna are taken as an example for illustration.

Those skilled in the art can understand that when the user holds the short sides of the communication device 1 with both hands, the communication device 1 is usually in a horizontal screen 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 manner is only an optional manner for defining that the communication device 1 is in a portrait screen state and a landscape screen state, and the embodiment of the present application is not limited to this manner.

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 the position area close to the bottom edge of the communication device 1 , and it is difficult to hold other position 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 position area close to the bottom edge of the communication device 1 , and it is difficult to hold other position areas of the communication device 1 .

Based on the above description and in conjunction with FIG. 3 and FIG. 4 , in order to apply to different scenarios in which the communication device 1 is in a portrait screen state and a landscape screen state, the embodiment of the present application may use the second Wi-Fi antenna (in FIG. 3 and FIG. A second Wi-Fi antenna is shown as an example) is set in the upper half area of the communication device 1 in the landscape state, so as to prevent the second Wi-Fi antenna from being blocked when the communication device 1 is in the landscape state. In this embodiment of the present application, the first Wi-Fi antenna (in FIG. 3 and FIG. 4 , a first Wi-Fi antenna is used as an example for illustration) may be set in the upper half area where the communication device 1 is in the vertical screen state, It is avoided that the first Wi-Fi antenna is blocked when the communication device 1 is in a vertical screen state.

Wherein, the embodiments of the present application do 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 top center of the communication device 1 . When the communication device 1 is in a vertical screen state, the first Wi-Fi antenna may be located at the top center of the communication device 1 .

In addition, since the communication device 1 is in the horizontal screen state, it is close to the support structure such as the desktop, which reduces the performance of the first Wi-Fi antenna. On the basis of the upper half area in the screen state, it is also necessary to set a preset distance between the first Wi-Fi antenna and the bottom edge of the communication device 1 in the landscape screen state. The preset distance may be equipment based on actual experience, which is not limited in this embodiment of the present application.

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 of the communication device 1 in the portrait state, and is located in the upper half area of the communication device 1 in the landscape state, therefore, regardless of whether the communication device 1 is in the landscape state or the portrait state The screen state, the third Wi-Fi antenna is not easy to hold.

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

Wherein, the embodiment of the present application does not limit the specific position and quantity 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 top center of the communication device 1 . When the communication device 1 is in a vertical screen state, the third Wi-Fi antenna may be located at the top center of the communication device 1 .

Continuing with reference to FIG. 5 , the communication device 1 may further include: a peripheral charging interface 16 (the peripheral charging interface 16 is illustrated by a plurality of circles in FIG. 5 ). The peripheral charging interface 16 is located in the lower half area of the communication device 1 in the first state, and the peripheral charging interface 16 is close to the bottom edge of the lower area, which is convenient for the communication device 1 to charge external devices.

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

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