Hereinafter, the technical solution of the communication device in the embodiment of the present application will be described with reference to the drawings in the embodiment of the present application.

Fig. 1 is a schematic structural diagram of an exemplary communication device provided in an embodiment of the present application, and as shown in fig. 1, the communication device 1 includes: a plurality of Wi-Fi antennas 11, a control circuit 12, a Wi-Fi chip 13, a peripheral chip 14 and a switch circuit 15.

The embodiment of the application does not limit the position, the specific size and the manufacturing process of the Wi-Fi antenna 11 in the communication device 1, and only the number of the Wi-Fi antennas 11 is required to be more than or equal to two.

Those skilled in the art will appreciate that in different application scenarios, the communication device 1 generally uses part of the Wi-Fi antenna 11 to implement Wi-Fi communication of the communication device 1, so that the rest of the Wi-Fi antenna 11 will be idle. And the location of each Wi-Fi antenna 11 at the communication device 1 is typically set after shipment of the communication device 1.

Based on the foregoing description, in the embodiment of the present application, according to the position of each Wi-Fi antenna 11 and by combining practical experience, a first preset antenna suitable for the communication device 1 to perform Wi-Fi communication and a second preset antenna suitable for the communication between the external device and the communication device 1 in each application scenario may be determined from the plurality of Wi-Fi antennas 11.

In the embodiment of the application, under the same application scenario, the first preset antenna and the second preset antenna are different. In different application scenarios, the first preset antenna and the second preset antenna may be the same or different. The number of the first preset antennas may be Multiple, so as to form a Multiple-Input Multiple-Output (MIMO) antenna, or may be one, which is not limited in this embodiment of the present application. The number of the second preset antennas may be one or multiple, so as to form a MIMO antenna to work, which is not limited in the embodiment of the present application.

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

In this way, the output end of the control circuit 12 is electrically connected to the control end of the switch circuit 15, and can control the connection or disconnection of a path between any input end and any output end of the switch circuit 15, so as to adjust whether the Wi-Fi chip 13 and the peripheral chip 14 are electrically connected to any Wi-Fi antenna 11, that is, adjust whether the Wi-Fi chip 13 and the peripheral chip 14 are electrically connected to the first preset antenna and the second preset antenna, respectively.

The control circuit 12 may be an original control circuit 12 in the communication device 1, or may be a newly added control circuit 12, which is not limited in this embodiment of the present application. For example, the control circuit 12 may be a Central Processing Unit (CPU) in the communication apparatus 1.

The embodiments of the present application do not limit the types and the numbers of the Wi-Fi chips 13 and the peripheral chips 14. And, the Wi-Fi chip 13 may include, but is not limited to, functions of collecting signals of the respective Wi-Fi antennas 11, analyzing performance of the respective Wi-Fi antennas 11, and warning whether the respective Wi-Fi antennas 11 are malfunctioning. The peripheral chip 14 may include, but is not limited to, functions of searching and matching the external device, collecting parameters of the external device, and acquiring a communication signal between the external device and the communication device 1.

The control circuit 12, the Wi-Fi chip 13, and the peripheral chip 14 may be discrete components or may be combined arbitrarily. For example, the control circuit 12, the Wi-Fi chip 13 and the peripheral chip 14 are integrally arranged, or the control circuit 12 and the Wi-Fi chip 13 are integrally arranged, or the control circuit 12 and the peripheral chip 14 are integrally arranged, which is not limited in this embodiment of the present application.

The embodiment of the present application does not limit the type and number of the switch circuits 15. Alternatively, the switch circuit 15 may be a switch integrated device such as a multi-pole multi-throw switch, or may be a circuit formed by combining a plurality of switches. For example, when the two output terminals of the switch circuit 15 are electrically connected to the first predetermined antenna and the second predetermined antenna, respectively, the switch circuit 15 may be a double-pole double-throw switch. For convenience of explanation, the switch circuit 15 in fig. 1 is illustrated as a double-pole double-throw switch.

Based on the above description, the peripheral chip 14 may send a matching success message to the control circuit 12 when the external device is successfully matched. The matching success message may include, but is not limited to, various forms of numbers, letters, binary values, and the like. In this way, the control circuit 12, upon receiving the matching success message, can know that there is an external device that needs to communicate with the communication device 1.

When knowing that the external device needs to communicate with the communication device 1, the control circuit 12 needs to provide not only the Wi-Fi antenna 11 for Wi-Fi communication to the communication device 1 but also the Wi-Fi antenna 11 suitable for communicating with the communication device 1 to the external device. Further, the control circuit 12 may perform the following operation procedures in parallel based on the foregoing description.

On one hand, the control circuit 12 can control the Wi-Fi chip 13 to be electrically connected with the first preset antenna by turning on a path between the input end of the switch circuit 15 electrically connected with the Wi-Fi chip 13 and the output end of the switch circuit 15 electrically connected with the first preset antenna, so as to implement Wi-Fi communication of the communication device 1.

Since the Wi-Fi chip 13 is electrically connected to the first preset antenna, the Wi-Fi chip 13 may control the communication device 1 to perform Wi-Fi communication through the first preset antenna, such as sending and receiving Wi-Fi signals required by the communication device 1, so as to ensure that the communication device 1 may perform normal Wi-Fi communication.

On the other hand, the control circuit 12 may control the peripheral chip 14 to be electrically connected to the second predetermined antenna by turning on a 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 predetermined antenna, so as to implement communication between the external device and the communication device 1.

Because the peripheral chip 14 is electrically connected to the second preset antenna, the peripheral chip 14 can control the external device to communicate with the communication device 1 through the second preset antenna, for example, send and receive Wi-Fi signals to the communication device 1, so that the second preset antenna can be used as a special antenna for the external device to communicate with the communication device 1, so as to ensure that the external device communicates with the communication device 1, and not only is the idle Wi-Fi antenna reasonably utilized, but also the cost is reduced without separately configuring the Wi-Fi antenna (for example, a 2.4GHz or 5GHz Wi-Fi antenna is separately configured for a keyboard and a mouse), thereby solving the problem that the performance is poor because the antenna needs to ensure good clearance, effectively reducing the difficulty of the overall layout and design of the antenna, and being suitable for various communication requirements with small time delay.

It should be noted that the communication device 1 may further include any one component, such as a display screen, a protective housing, a rear cover, a front frame, a circuit board, and a battery, which is not limited in this embodiment of the application.

According to the communication device provided by the embodiment of the application, the first preset antenna and the second preset antenna are arranged in the plurality of Wi-Fi antennas in advance, wherein the first preset antenna is used for Wi-Fi communication of the communication device, and the second preset antenna is used for communication between the external device and the communication device. And two output ends of the switch circuit are respectively and electrically connected with the first preset antenna and the second preset antenna, the first input end of the switch circuit is electrically connected with the signal end of the Wi-Fi chip, the second input end of the switch circuit is electrically connected with the signal end of the peripheral chip, the output end of the control end of the switch circuit is electrically connected, and the output end of the peripheral chip is electrically connected with the input end of the control circuit. Based on the electrical connection relationship, when the peripheral chip is successfully matched with the external device, the peripheral chip can send a matching success message to the control circuit. When the control circuit receives the matching success message, the Wi-Fi chip can be controlled by the switch circuit to be electrically connected with the first preset antenna and the peripheral chip can be controlled to be electrically connected with the second preset antenna. Therefore, the Wi-Fi chip can control the communication equipment to carry out Wi-Fi communication through the first preset antenna, and the peripheral chip can control the external equipment to carry out communication with the communication equipment through the second preset antenna. In the embodiment of the application, normal Wi-Fi communication of the communication equipment can be guaranteed, communication between the communication equipment and the external equipment can be achieved by reasonably utilizing the idle Wi-Fi antenna, the difficulty of overall layout of the antenna is reduced without adding a new Wi-Fi antenna, the utilization rate of the Wi-Fi antenna is improved, the communication speed between the external equipment and the communication equipment is improved, various low-delay scenes are met, a user can flexibly operate the Wi-Fi antenna, and the external equipment is convenient to use for the user.

Exemplarily, on the basis of the embodiment shown in fig. 1, the communication device 1 according to the embodiment of the present application further has an idle Wi-Fi antenna 11 on the premise of ensuring normal Wi-Fi communication, so that the peripheral chip 14 can implement external device search by using the idle Wi-Fi antenna 11 in addition to the conventional bluetooth technology. Next, with reference to fig. 2, a detailed description will be given of an implementation process of the peripheral chip 14 in the embodiment of the present application for searching for an external device by using the Wi-Fi antenna 11.

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

In the embodiment of the application, under the same application scene, 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, so as to form a MIMO antenna, or may be one, which is not limited in this embodiment of the present application. The number of the second target antennas may be one or multiple, so as to form a MIMO antenna to operate, which is not limited in this embodiment of the application.

In the embodiment of the present application, the basis for determining the quality of communication of each Wi-Fi antenna 11 is not limited. For example, the Wi-Fi chip 13 may determine a Received Signal Strength Indication (RSSI) of each Wi-Fi antenna 11 according to the collected signal of each Wi-Fi antenna 11, and determine the communication quality of each Wi-Fi antenna 11 according to the RSSI 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 one Wi-Fi antenna 11, that is, the output side of the switch circuit 15 is electrically connected to a first target antenna and a second target antenna. And a first input end of the switch circuit 15 is electrically connected with a signal end of the Wi-Fi chip 13, and a second input end of the switch circuit 15 is electrically connected with a signal end of the peripheral chip 14.

In this way, the output end of the control circuit 12 is electrically connected to the control end of the switch circuit 15, and can control the on/off of a path between any input end and any output end of the switch circuit 15, so as to adjust whether the Wi-Fi chip 13 and the peripheral chip 14 are electrically connected to any Wi-Fi antenna 11, that is, adjust 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 may send the determination result to the control circuit 12 through an electrical connection with the second input terminal of the control circuit 12. The judgment result may include, but is not limited to, a number, a second-level system value, a letter, a character, and other various forms for representing. Thus, the control circuit 12 can know that the communication quality of the first target antenna is better than that of the second target antenna when receiving the judgment result, and can implement Wi-Fi communication of the communication device 1 through the first target antenna and implement a process of searching for an external device by the peripheral chip 14 through the second target antenna.

Further, the control circuit 12 may execute the following operation processes in parallel.

On one hand, the control circuit 12 may control the Wi-Fi chip 13 to be electrically connected with the first target antenna by turning on a path between the input end of the switch circuit 15 electrically connected with the Wi-Fi chip 13 and the output end of the switch circuit 15 electrically connected with the first target antenna, so as to implement the 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 may control the communication device 1 to perform Wi-Fi communication through the first target antenna, such as sending and receiving Wi-Fi signals required by the communication device 1, to ensure that the communication device 1 can perform normal Wi-Fi communication.

On the other hand, the control circuit 12 may control the peripheral chip 14 to be electrically connected to the second target antenna by turning on a 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, so as to implement the function of the peripheral chip 14 to search for the external device.

Since the peripheral chip 14 is electrically connected to the second target antenna, the peripheral chip 14 may control the peripheral chip 14 to search for the external device through the second target antenna. For example, when the external device is turned on and placed within a certain distance from the peripheral chip 14, the peripheral chip 14 may search for the external device through the second target antenna. Further, the peripheral chip 14 may match the searched external device, such as checking whether the external device is an authorized device, determining whether the operating environment of the external device is safe, and the like. In general, if the external device and the peripheral chip 14 are not matched, the peripheral chip 14 may be matched with the searched external device. If the external device and the peripheral chip 14 are successfully matched, the peripheral chip 14 may be directly and successfully matched with the searched external device.

The communication equipment provided by the embodiment of the application is electrically connected with a first target antenna and a second target antenna through two output ends of a switch circuit respectively, a first input end of the switch circuit is electrically connected with a signal end of a Wi-Fi chip, a second input end of the switch circuit is electrically connected with a signal end of a peripheral chip, an output end of the Wi-Fi chip is electrically connected with an input end of a control circuit, and an output end of the control circuit is electrically connected with a control end of the switch circuit. Based on the electrical connection relationship, the Wi-Fi chip can judge the communication quality of the 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 superior to that of the second target antenna. When the control circuit receives the judgment result, the first target antenna can be determined to be used for the communication device to carry out Wi-Fi communication, the second target antenna is used for the external chip to search for external equipment, and the Wi-Fi chip and the first target antenna can be controlled to be electrically connected through the switch circuit, and the external equipment chip and the second target antenna can be controlled to be electrically connected through the switch circuit. Therefore, the Wi-Fi chip can control the communication device to carry out 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 embodiment of the application, normal Wi-Fi communication of the communication equipment can be guaranteed, idle Wi-Fi antennas can be reasonably utilized, the process that external chips search for external equipment is achieved, the utilization rate of the Wi-Fi antennas is improved, the Wi-Fi antennas are enabled to be optimized and multiplexed, and the use performance of the Wi-Fi antennas is effectively guaranteed while the number of the Wi-Fi antennas is reduced.

In addition, when the communication device 1 performs Wi-Fi communication through the first target antenna and the peripheral chip 14 searches for and matches a successful 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 knows that the external device needs to communicate with the communication device 1. Thus, the control circuit 12 may determine that it is necessary to control the Wi-Fi chip 13 to be electrically connected to the first predetermined antenna, and that it is necessary to control the peripheral chip 14 to be electrically connected to the second predetermined 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 the connection or disconnection of the path between the input terminal and the output terminal of the switch circuit 15, the control circuit 12 may set in advance that the Wi-Fi chip 13 is electrically connected to the first preset antenna through the switch circuit 15, and the peripheral chip 14 is electrically connected to the second preset antenna through the switch circuit 15 in a preset state.

To accomplish this, control circuit 12 may adjust the current state of switching circuit 15 to a preset state. At this time, 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, so that the control circuit 12 can obtain the current state of the switch circuit 15, that is, the current state is a state in which 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 electrically connected with the first preset antenna and the peripheral chip 14 can be electrically connected with the 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 may lock the current state of the switch circuit 15, so that the Wi-Fi chip 13 may control the communication device 1 to perform Wi-Fi communication through the first target antenna (i.e., the first preset antenna), and the peripheral chip 14 controls the external device to perform communication with the communication device 1 through the second target antenna (i.e., 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 may update the current state of the switch circuit 15 to the preset state, so that the Wi-Fi chip 13 may be switched to be electrically connected to the first preset antenna through the switch circuit 15, thereby implementing a process of Wi-Fi communication of the communication device 1 through the first preset antenna, and the peripheral chip 14 may be switched to be electrically connected to the second preset antenna through the switch circuit 15, thereby implementing a communication process between the external device and the communication device 1 through the second preset antenna.

Optionally, after updating the current state of the switch circuit 15 to the preset state, the control circuit 12 may also lock the current state of the switch circuit 15, that is, the state where the Wi-Fi chip 13 is electrically connected to the first preset antenna and the peripheral chip 14 is electrically connected to the second preset antenna.

In the embodiment of the 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 is successfully matched with the external device, the control circuit can judge whether the current state of the switch circuit is a preset state. If yes, 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, so that 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 with the first preset antenna and the peripheral chip is electrically connected with the second preset antenna. Therefore, the communication device can carry out Wi-Fi communication through the first preset antenna, and the external device can carry out communication with the communication device through the second preset antenna.

For example, in the embodiment of the present application, the first predetermined antenna and the second predetermined antenna may be located at any positions of the communication device 1, and are usually set in combination with practical experience. The positions of the first default antenna and the second default antenna are described below with reference to fig. 3-4. For convenience of illustration, the plurality of Wi-Fi antennas 11 is illustrated as including a first Wi-Fi antenna and a second Wi-Fi antenna.

It will be understood by those skilled in the art that when the user holds the short side of the communication apparatus 1 with both hands, the communication apparatus 1 is normally in the landscape state, as shown in fig. 3. When the user holds the long side of the communication apparatus 1 with both hands, the communication apparatus 1 is normally in the portrait screen state as shown in fig. 4. It should be noted that the above manner is only one optional manner for defining the communication device 1 in the portrait screen state and the landscape screen state, and the embodiment of the present application is not limited to this manner.

As shown in fig. 3, when the communication apparatus 1 is in the landscape state, the user can hold the position area of the short side of the communication apparatus 1 near the bottom side of the communication apparatus 1 more easily, and can not hold the other position areas of the communication apparatus 1 easily. As shown in fig. 4, when the communication apparatus 1 is in the portrait state, the user can hold the position area on the long side of the communication apparatus 1 and near the bottom side of the communication apparatus 1 more easily, and can not hold the other position areas of the communication apparatus 1 easily.

Based on the above description, with reference to fig. 3 and 4, in order to be applicable to different scenarios when the communication device 1 is in the portrait screen state and the landscape screen state, in the embodiment of the present application, a second Wi-Fi antenna (illustrated by taking one second Wi-Fi antenna as an example in fig. 3 and 4) may be disposed in the upper half area when the communication device 1 is in the landscape screen state, so as to avoid the second Wi-Fi antenna from being blocked when the communication device 1 is in the landscape screen state. In the embodiment of the application, the first Wi-Fi antenna (illustrated in fig. 3 and 4 by taking one first Wi-Fi antenna as an example) may be disposed in the upper half area of the communication device 1 in the vertical screen state, so that the first Wi-Fi antenna is prevented from being blocked when the communication device 1 is in the vertical screen state.

The embodiment of the application does not limit the specific positions and the number of the first Wi-Fi antenna and the second Wi-Fi antenna. For example, the second Wi-Fi antenna may be located in a central position on the top of the communication device 1 in the landscape state of the communication device 1. The first Wi-Fi antenna may be located in a central position of the top of the communication device 1 in the portrait screen state of the communication device 1.

Because the communication device 1 is tightly attached to the supporting structures such as the desktop when in the landscape state, and the performance of the first Wi-Fi antenna is reduced, in the embodiment of the present application, on the basis that the first Wi-Fi antenna is disposed in the upper half area of the communication device 1 in the portrait state, it is also necessary to set that the first Wi-Fi antenna has a preset distance from the bottom side of the communication device 1 in the landscape state. The preset distance may 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, the first Wi-Fi antenna is more likely to be held by hand and the performance of the first Wi-Fi antenna is degraded than the second Wi-Fi antenna, so that the second Wi-Fi antenna may be set as the first preset antenna in advance, and the first Wi-Fi antenna may be set as the second preset antenna in the embodiment of the present application.

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 more likely to be held by a hand and the performance of the second Wi-Fi antenna is reduced, so that the first Wi-Fi antenna may be set as the first preset antenna in advance, and the second Wi-Fi antenna may be set as the second preset antenna in the embodiment of the present application.

On the basis of the embodiments shown in fig. 3 to 4, as shown in fig. 5 (for convenience of explanation, 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 (one third Wi-Fi antenna is illustrated in fig. 5). Wherein, the other signal terminal of the Wi-Fi chip 13 is electrically connected with a third Wi-Fi antenna.

Since the third Wi-Fi antenna is located in the upper half area of the communication device 1 in the vertical screen state and in the upper half area of the communication device 1 in the horizontal screen state, the third Wi-Fi antenna is not easily held by a hand no matter the communication device 1 is in the horizontal screen state or the vertical screen state.

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

The embodiment of the application does not limit the specific position and number of the third Wi-Fi antenna. For example, the third Wi-Fi antenna may be located in a central position on the top of the communication device 1 in the landscape state of the communication device 1. The third Wi-Fi antenna may be located at a central position of the top of the communication device 1 in the portrait screen state of the communication device 1.

With continued reference to fig. 5, the communication device 1 may further include: the 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 half area, so that the communication device 1 can charge the external device conveniently.

The specific location, number and type of the charging interface 16 are not limited in the embodiment of the present application. In addition, the first state may be a horizontal screen state or a vertical screen state, which is not limited in this application embodiment. For example, the peripheral charging interface 16 may be located at the center of the bottom side of the communication device 1 in the landscape state 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 a center position of a bottom side of the communication device 1.

For example, if the communication device 1 is a tablet, the tablet case is covered with the tablet case, and the external device is placed on the tablet case, at this time, the tablet can be charged to the external device through the tablet case via the peripheral charging interface 16. It should be noted that the above charging method is only an exemplary method for charging the external device by the communication device 1 through the peripheral charging interface 16, and the embodiment of the present application is not limited to the above charging method.

For example, the present application further provides an antenna switching method, which may be implemented by the communication device in the embodiments shown in fig. 1 to 5 in a software and/or hardware manner, and may be implemented by setting a first preset antenna and a second preset antenna in advance from a plurality of Wi-Fi antennas, where the first preset antenna is used for Wi-Fi communication of the communication device, and the second preset antenna is used for communication between an external device and the communication device, so that based on an electrical connection relationship between components in the communication device, not only normal Wi-Fi communication of the communication device may be implemented through the first preset antenna, but also communication between the communication device and the external device may be implemented through an idle Wi-Fi antenna (i.e., the second preset antenna), so as to improve a utilization rate of the Wi-Fi antenna and improve a communication rate between the external device and the communication device, various scenes with low time delay in operation are met, and flexible operation and convenient use of a user are guaranteed.

Fig. 6 is a flowchart of an exemplary antenna switching method according to an embodiment of the present application. As shown in fig. 6, an antenna switching method according to an embodiment of the present application may include:

s101, the peripheral chip sends a matching success message to the control circuit, wherein the matching success message is used for indicating that the peripheral chip and the external equipment are successfully matched.

S102, when the control circuit receives the matching success message, the Wi-Fi chip is controlled to be switched to be electrically connected with a first preset antenna through the switch circuit, the peripheral chip is controlled to be switched to be electrically connected with a second preset antenna through the switch circuit, the first preset antenna and the second preset antenna are arranged in advance from the plurality of Wi-Fi antennas, the first preset antenna is used for Wi-Fi communication of the communication equipment, and the second preset antenna is used for communication between the external equipment and the communication equipment.

S103, controlling the communication equipment to carry out Wi-Fi communication through the first preset antenna by the Wi-Fi chip.

And S104, the peripheral chip controls the external equipment to communicate with the communication equipment through a second preset antenna.

The antenna switching method provided in this embodiment of the present application may adopt the communication device in the embodiment of fig. 1 to perform a process, and an implementation manner and a technical effect thereof are similar, and this embodiment of the present application is not described herein again.

For example, the antenna switching method according to the embodiment of the present application may further be configured to, when it is determined 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 between each component in the communication device, not only achieve normal Wi-Fi communication of the communication device through the first target antenna, but also achieve a process of searching for an external device by using an idle Wi-Fi (i.e., the second target antenna), so as to improve a utilization rate of the Wi-Fi antenna.

Fig. 7 is a flowchart of an exemplary antenna switching method according to an embodiment of the present application. As shown in fig. 7, an antenna switching method according to an embodiment of the present application may include:

s201, the Wi-Fi chip judges the communication quality of the Wi-Fi antennas.

S202, the Wi-Fi chip sends a judgment result to the control circuit, wherein the judgment result is that the communication quality of the first target antenna is superior to that of the second target antenna, the first target antenna is used for Wi-Fi communication of the communication equipment, and the second target antenna is used for searching the external equipment by the peripheral chip.

S203, when the control circuit receives the judgment result, the Wi-Fi chip is controlled to be switched to be electrically connected with the first target antenna through the switch circuit, and the peripheral chip is controlled to be switched to be electrically connected with the second target antenna through the switch circuit.

And S204, the Wi-Fi chip controls the communication equipment to carry out Wi-Fi communication through the first target antenna.

And S205, the peripheral chip controls the peripheral chip to search the peripheral through the second target antenna.

The antenna switching method provided in this embodiment of the present application may adopt the communication device in the embodiment of fig. 2 to perform a process, and an implementation manner and a technical effect thereof are similar, and this embodiment of the present application is not described herein again.

In addition, the communication device may perform the steps shown in fig. 7 such that the communication device performs Wi-Fi communication through the first target antenna and the external device chip searches for the external device through the second target antenna. When the peripheral chip searches for the external device by using the second target antenna and successfully matches the external device, the communication device may perform the steps shown in fig. 6, so that the communication device performs Wi-Fi communication through the first preset antenna, and the external device communicates with the communication device through the second preset antenna.

However, since the Wi-Fi chip is electrically connected to the first target antenna and the peripheral chip is electrically connected to the second target antenna at the end of the step shown in fig. 7, it can be seen that the current state of the switch circuit is a state in which the Wi-Fi chip is electrically connected to the first target antenna through the switch circuit and the peripheral chip is electrically connected to the second target antenna through the switch circuit. However, in the step shown in fig. 6, the Wi-Fi chip needs to be electrically connected to the first predetermined antenna, and the peripheral chip needs to be electrically connected to the second predetermined antenna. For convenience of description, the preset state of the switch circuit may be set in advance to a state in which 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 above description, before the communication device performs the steps shown in fig. 6, the control circuit may optionally determine whether the current state of the switch circuit is a preset state.

When the control circuit judges 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 equipment to carry out Wi-Fi communication through the first target antenna (namely the first preset antenna), and the peripheral chip controls the external equipment to carry out communication with the communication equipment through the second target antenna (namely the second preset antenna).

When the control circuit judges that the current state of the switch circuit is not the preset state, the control circuit can update the current state of the switch circuit to the preset state so as to control the Wi-Fi chip to be switched to be electrically connected with the first preset antenna through the switch circuit and control the peripheral chip to be switched to be electrically connected with the second preset antenna through the switch circuit.

Optionally, after the control circuit updates the current state of the switch circuit to the preset state, the current state of the switch circuit may be locked, that is, the Wi-Fi chip is electrically connected to the first preset antenna, and the peripheral chip is electrically connected to the second preset antenna.

In the embodiment of the 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 can judge whether the current state of the switch circuit is a preset state. If yes, 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, so that 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 with the first preset antenna and the peripheral chip is electrically connected with the second preset antenna. Thus, the communication device can perform Wi-Fi communication through the first preset antenna, and the external device can perform communication with the communication device through the second preset antenna.
