Detailed Description

The technical solutions of the present disclosure will be described below clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments of the present disclosure, but not all embodiments. All other embodiments, which can be derived by one of ordinary skill in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure. In addition, technical features involved in different embodiments of the present disclosure described below may be combined with each other as long as they do not conflict with each other.

Fig. 1 shows a schematic configuration diagram of an electronic device in the related art. The electronic device may be a wearable device or a mobile terminal, such as a smart watch, a smart phone, and the like, and for ease of understanding, the following description takes a wrist-worn device or a smart watch as an example, but the embodiments of the present disclosure are not limited thereto.

As shown in fig. 1, the smart watch includes a watch head 10 and a wrist band, and for clarity of explanation, only the watch head 10 is shown in fig. 1, and the wrist band structure is not shown. In the orientation shown in fig. 1, the front of the wristwatch, i.e., the side on which the screen is displayed, is above the watch head 10, and the back of the wristwatch, i.e., the side close to the wrist of the person, is below the watch head 10.

The smart watch comprises an NFC antenna and a wireless charging antenna, and the NFC antenna and the wireless charging antenna are used for achieving NFC communication and wireless charging functions. Near Field Communication (NFC) is a Near Field wireless Communication technology, and is widely applied in mobile payment, electronic ticketing, entrance guard identification, electronic ID, and other scenarios.

In the related art, in order to improve the performance of NFC communication, the NFC antenna 11 is usually disposed on a side close to the front of the watch, for example, below the screen assembly, and accordingly, when a user uses the watch to implement functions such as NFC payment, the front of the watch needs to be close to the card swiping machine. For the wireless charging scenario, the wireless charging antenna 12 is usually disposed on a side close to the back of the watch, such as the inner side of the bottom case. Thus, when wirelessly charging the watch, the user is required to bring the back of the watch close to the charger.

The inventor finds out through research that the device structure cannot meet the use requirement in partial scenes. For example, in an example scenario, when the electronic device performs wireless charging, the screen of the device is facing upward, and if the user does not want to be disturbed by the screen information, the wireless charging cannot be performed if the screen of the device is facing downward. For another example, in another exemplary scenario, when the device performs NFC card swiping, the screen is facing downward, and if the NFC antenna is used for a long time such as when an access card is generated in a simulation mode, the user cannot view the screen because the screen is facing downward, and therefore the user experience is affected because the user cannot view the screen information in time.

Therefore, in the electronic equipment in the related art, under the scenes of wireless charging or wireless communication and the like, the limitation on the degree of freedom of equipment use is large, bad use experience is brought to a user, and the use requirement is difficult to meet.

Based on the defects in the related art, the embodiments of the present disclosure provide an electronic device, a control method thereof, and a storage medium, and aim to improve convenience for a user to use the electronic device in wireless charging and wireless communication scenarios and improve user experience.

The disclosed embodiments provide an electronic device, which may be a wearable device or any device type suitable for implementation, such as a wrist-worn device like a smart watch or a smart bracelet, a head-worn device like a headset or smart glasses, and a mobile terminal like a smart phone or a tablet computer, and the disclosure is not limited thereto.

In some implementations, an electronic device exemplified by the present disclosure includes a housing, which may include a bezel and a bottom case of a smart watch, for example, a smart watch.

The electronic device of the disclosed example includes at least two NFC antennas that may be disposed inside the housing. Each NFC antenna can be used for both communication and charging.

In some embodiments, the at least two NFC antennas may be respectively located at different locations within the housing. For example, taking a smart watch as an example, the at least two NFC antennas include a first NFC antenna disposed on one side close to the front surface of the watch and a second NFC antenna disposed on one side close to the back surface of the watch, or may further include NFC antennas disposed on other positions of the watch. It is understood that the number and the location of the NFC antennas in the embodiments of the present disclosure need not be limited, and those skilled in the art may set the number and the location according to specific requirements.

In the embodiments of the present disclosure, the NFC antenna is used to switch between the wireless charging function and the wireless communication function, which will be described in detail below.

The electronic equipment also comprises a wireless charging circuit and a wireless communication circuit which are arranged in the shell. The wireless charging circuit is a related circuit module for realizing wireless charging, is connected with the NFC antenna, and charges the equipment battery through an electromagnetic induction signal of the NFC antenna. In some embodiments, the wireless charging Circuit may be implemented as a charging IC (Integrated Circuit Chip), which may manage the charging voltage and the charging path. The wireless communication circuit is a related circuit module for realizing wireless communication, and is connected with the NFC antenna, so that a communication signal can be received or sent through the NFC antenna, for example, in an NFC payment scenario, a payment signal can be received or sent through the NFC antenna. In some embodiments, the wireless communication circuit may be implemented as an NFC chip that may enable processing of signals received by the NFC antenna. With respect to the principles of wireless charging circuits and wireless communication circuits, those skilled in the art will understand and fully implement the same with reference to the related art, and detailed descriptions thereof are omitted for the present disclosure.

The electronic device of the embodiment of the present disclosure further includes a switching circuit, where the switching circuit includes at least one first terminal and at least one second terminal, the at least one first terminal is used to electrically connect at least one of the at least two NFC antennas, the at least one second terminal is used to electrically connect at least one of the wireless charging circuit and the wireless communication circuit, and the switching circuit is used to control on/off of electrical connections between the at least two NFC antennas and the wireless charging circuit and between the at least two NFC antennas and the wireless communication circuit. Therefore, the switching circuit can realize switching communication between any NFC antenna and the wireless charging circuit and between any NFC antenna and the wireless communication circuit.

In some embodiments, the switching circuit may be implemented by using MOS transistors, that is, one MOS transistor is disposed on a connection circuit between each NFC antenna and the wireless charging circuit or the wireless communication circuit, so that the connection circuit between the NFC antenna and the wireless charging circuit or the wireless communication circuit may be switched by controlling on/off of the MOS transistor.

In some embodiments, the wireless communication circuit, the wireless charging circuit, and the switching circuit described in the examples of the present disclosure may be related functional modules integrated on a motherboard of an electronic device, which can be understood and fully implemented by those skilled in the art, and are not described in detail in the present disclosure.

It can be understood that, in the electronic device according to the embodiments of the present disclosure, each NFC antenna may implement switching communication with the wireless charging circuit or the wireless communication circuit through the switching circuit. Thus, when the NFC antenna is electrically connected with different circuits, different functions can be realized. For example, when the NFC antenna is connected to the NFC communication chip, a wireless communication function, such as NFC card payment, may be implemented; and when the NFC antenna is connected with the charging chip, the function of wireless charging can be realized. The present disclosure is described in detail below, and will not be described in detail here.

Through the above, the electronic equipment of the embodiment of the present disclosure can switch and communicate each NFC antenna with the wireless charging circuit and the wireless communication circuit through the switching circuit, so that each NFC antenna can be used as a wireless charging or wireless communication antenna, the use freedom of communication scenes such as charging and payment of wearable equipment is higher, the operation of a user is facilitated, and better charging and communication performances can be achieved.

In some embodiments, an electronic device of examples of the present disclosure includes a controller, the controller being a master control element of a wearable device. As in the example of fig. 2, the controller may include the processor 110 and the memory 120, while the electronic device further includes a wireless charging circuit 141, a wireless communication circuit 142, and a switching circuit 150.

The processor 110 may be of any type, having one or more processing cores. The system can execute single-thread or multi-thread operation and is used for analyzing instructions to execute the operations of acquiring data, executing logical operation functions and issuing operation processing results.

In some embodiments, the processor 110 may be implemented as a Central Processing Unit (CPU) Chip, a Micro Controller Unit (MCU) Chip, a System on Chip (SoC) Chip, a bluetooth main control Chip, etc., and those skilled in the art may specifically set the CPU Chip, the MCU Chip, the SoC Chip, the bluetooth main control Chip, etc., according to different types of wearable devices, which is not limited by the disclosure.

The memory 120 may include a non-volatile computer-readable storage medium, such as at least one magnetic disk storage device, flash memory device, or other non-volatile solid state storage device. Memory 120 may have a program storage area for storing non-volatile software programs, non-volatile computer-executable programs, and modules for calling by processor 110 to cause processor 110 to perform one or more method steps as described below. The memory 120 may further include a storage portion, such as a volatile random access medium or a hard disk, as a data storage area for storing the operation processing result and data issued and output by the processor 110.

The wireless charging circuit 141 is a relevant circuit module for implementing wireless charging, for example, in the embodiment of the present disclosure, the wireless charging circuit 141 may be a charging chip matched with an NFC wireless charging protocol. The wireless communication circuit 142 is a relevant circuit module for implementing wireless communication, for example, in the embodiment of the present disclosure, the wireless communication circuit 142 may be an NFC radio frequency chip matched with an NFC antenna.

In the example of fig. 2, the electronic device is a wearable device, the wearable device includes two NFC antennas, that is, a first NFC antenna 161 and a second NFC antenna 162, and the first NFC antenna 161 and the second NFC antenna 162 may be respectively disposed on two sides of the wearable device.

The switching circuit 150 includes two first terminals, two second terminals, and a control terminal. One of the two first terminals is electrically connected to the first NFC antenna 161, and the other is electrically connected to the second NFC antenna 162. One of the second terminals is electrically connected to the wireless charging circuit 141, and the other is electrically connected to the wireless communication circuit 142. The control terminal may be coupled to the processor 110 via a bus 130. Accordingly, the switching circuit 150 may control on/off between the NFC antenna and the wireless charging circuit 141 or the wireless communication circuit 142 according to a control instruction issued by the processor 110.

In an example, the switching circuit 150 may be implemented by using MOS transistors, that is, one MOS transistor is disposed on 4 connection circuits, including the first NFC antenna 161 and the wireless charging circuit 141, the first NFC antenna 161 and the wireless communication circuit 142, the second NFC antenna 162 and the wireless charging circuit 141, and the second NFC antenna 162 and the wireless communication circuit 142, and control terminals of the MOS transistors are all connected to the processor 110. Therefore, the processor 110 controls the on/off of the MOS transistor, so that the switching and conduction of the connection circuit can be realized. This can be understood and fully implemented by those skilled in the art, and the present disclosure will not be described in detail.

In some embodiments of the present disclosure, the first NFC antenna 161 and the second NFC antenna 162 of the wearable device are both NFC antennas, that is, antennas with a resonant frequency of 13.56 MHz.

It is to be understood that the number of NFC antennas of the wearable device in the example of the present disclosure is not limited to two shown in fig. 2, and may be any other number suitable for implementation, for example, 3, 4, etc., and those skilled in the art may set the number according to a specific device structure, which is not limited by the present disclosure.

Fig. 3 shows some specific embodiments of the electronic device of the present disclosure, and in some embodiments, the electronic device is an example of a smart watch, and the electronic device of the example of the present disclosure is specifically described with reference to fig. 2 and 3.

As shown in fig. 3, only the main body head portion of the smart watch is shown, which is not shown for the wrist band structure, and it can be understood by those skilled in the art that the present disclosure need not be described in detail.

The meter head of the intelligent watch comprises a shell 172, wherein the shell 172 is a main supporting structure of the meter head, and the shell 172 is of a groove-type structure and can be internally provided with electric elements of the watch. The screen assembly 171 is secured to the open end of the housing 172 to form the display area of the watch.

The inside of the housing 172 is also provided with a main board 180, a first NFC antenna 161, and a second NFC antenna 162. It is understood that other electrical elements, such as a battery, a vibration motor, a sensor, etc., are also disposed inside the smart watch, and the details of the disclosure are not repeated herein.

In this embodiment, the first NFC antenna 161 is disposed on a first side of the watch, i.e., a side near the front of the watch, for example, the first NFC antenna 161 is disposed below the screen assembly 171. While the second NFC antenna 162 is disposed on a second side of the watch, i.e., a side near the back of the watch, e.g., the second NFC antenna 162 is disposed at the bottom inside the housing 172.

The main board 180 is located between the first NFC antenna 161 and the second NFC antenna 162, the wireless charging circuit 141, the wireless communication circuit 142, and the switching circuit 150 according to the present disclosure may be integrated on the main board 180, and the first NFC antenna 161 and the second NFC antenna 162 may be connected to the switching circuit 150 on the main board 180 through a coaxial line, for example.

It can be understood that the first NFC antenna 161 and the second NFC antenna 162 are disposed on two opposite sides of the watch, so that the priority of the two antennas is different in different usage scenarios. In an exemplary scenario, when a user wears a watch to perform an NFC card swiping operation, according to a usage habit of the user, the user often turns over the wrist to make the screen component 171 of the watch close to the card swiping device, that is, the first NFC antenna 161 is closer to the card swiping device, and at this time, the communication efficiency of the first NFC antenna 161 is better than that of the second NFC antenna 162. In another exemplary scenario, when the user places the watch right side up on the wireless charger, the second NFC antenna 162 is closer to the wireless charger, and the charging efficiency of the second NFC antenna 162 is better than that of the first NFC antenna 161.

In some embodiments of the present disclosure, the switching circuit 150 may be set to control the first NFC antenna 161 and the wireless communication circuit 142 to be conducted and the second NFC antenna 162 and the wireless charging circuit 141 to be conducted in a default state according to the usage habit of the user. Alternatively, the switching circuit 150 may be set to control the electrical connection between the first NFC antenna 161 or the second NFC antenna 162 and the wireless communication circuit 142 and the wireless charging circuit 141 to be conductive in a default state. Alternatively, the switching circuit 150 may be set to control, in a default state, the first NFC antenna 161 and the second NFC antenna 162 to be electrically disconnected from the wireless communication circuit 142 and the wireless charging circuit 141, and to conduct the corresponding link only when it is determined that NFC communication or NFC charging is required, or to implement this in other implementation manners, which is not limited in the embodiment of the present disclosure.

In some implementations, the electronic device further includes at least one sensor, such as shown in fig. 2, the smart watch includes a sensor 200. The sensor 200 may be used to detect pose information of the device to obtain a current use state of the watch, so as to determine to select a target antenna suitable for the current use state, so as to ensure charging or communication efficiency.

In one example, the sensor 200 may employ an acceleration sensor or a gyroscope so that pose information of the device can be obtained, such as face-up or back-up. The present disclosure is specifically illustrated in the following method embodiments, which will not be described in detail here.

In some embodiments, the sensor 200 may be used to detect the location information of the terminal device that establishes a connection with the electronic device, for example, the terminal device is on the side near the front of the electronic device or on the side near the back of the electronic device, so as to determine to select a target antenna suitable for the current status, so as not to affect the use of the electronic device by the user. In some embodiments, the terminal device is on a side near the front of the electronic device, and the first NFC antenna is used as the target antenna. In other embodiments, the terminal device is on a side close to the back of the electronic device, and the second NFC antenna is used as the target antenna, which is not limited to this embodiment of the disclosure.

In some embodiments, after determining the target antenna, a prompt may be entered, such as by screen or voice, to prompt the user whether to agree to do so. For example, the user may be prompted as to whether he agrees to bring the watch right next to the swipe machine, whether he agrees to take the watch down for charging, and so forth. In some examples, the determined target antenna may be kept unchanged if an instruction indicating consent from the user is received. In some examples, if a user instruction indicating feedback is received, the other NFC antenna may be used as a target antenna, and wireless communication or wireless charging may be performed using the changed target antenna. Optionally, in the process of charging or communicating by using the changed target antenna, a switching instruction of a user may be received or it may be determined whether the target antenna performs a charging or communicating function that meets the requirement, and the target antenna may be switched again when a switching condition is met, which is not limited to this embodiment of the disclosure.

It is understood that, as shown in fig. 3, after determining the target antenna from the first NFC antenna 161 and the second NFC antenna 162, the processor 110 may determine that the watch is currently to perform an operation according to the sensing information received by the NFC antennas. For example, if it is determined that the currently performed operation of the watch is a wireless charging operation, the switching circuit 150 may be controlled to connect the target antenna with the wireless charging circuit 141. And for example, to determine that the watch is to perform an NFC payment operation, the switching circuit 150 may be controlled to communicate the target antenna with the wireless communication circuit 142. The operation principle of the wearable device according to the embodiment of the present disclosure is described below with reference to several practical scenarios.

In an example scenario one, the user wears the watch shown in fig. 3 for NFC payment, and according to usage habits, the user flips his wrist so that the screen assembly 171 approaches the card reader. The first NFC antenna 161 receives the sensing information sent by the card reader, and the processor 110 determines that the current payment information is the payment information according to the sensing information, and further determines that the wireless communication circuit 142 is the target circuit. And the sensor 200 will detect the pose information of the watch, so that the processor 110 determines that the watch is facing down according to the pose information detected by the sensor 200, and determines the first NFC antenna 161 as the target antenna. The processor 110 may then control the switching circuit 150 such that the first NFC antenna 161 is in communication with the wireless communication circuit 142 to enable NFC payment.

In example scenario two, the user holds the watch shown in fig. 3 and places the watch right side up over the NFC swipe. The second NFC antenna 162 receives the sensing information sent by the card reader, and the processor 110 determines that the current payment information is the payment information according to the sensing information, and further determines that the wireless communication circuit 142 is the target circuit. And the sensor 200 will detect the pose information of the watch, so that the processor 110 determines that the watch is right side up according to the pose information detected by the sensor 200, and determines the second NFC antenna 162 as the target antenna. The processor 110 may then control the switching circuit 150 such that the second NFC antenna 162 is in communication with the wireless communication circuit 142 to enable NFC payment.

In example scenario three, the user places the watch shown in fig. 3 right side up on the wireless charger. The second NFC antenna 162 receives the sensing information sent by the charger, and the processor 110 determines that the current charging information is charging information according to the sensing information, that is, the wireless charging circuit 141 is determined as a target circuit. And the sensor 200 will detect the pose information of the watch, so that the processor 110 determines that the watch is right side up according to the pose information detected by the sensor 200, and determines the second NFC antenna 162 as the target antenna. The processor 110 may then control the switching circuit 150 to enable the second NFC antenna 162 to communicate with the wireless charging circuit 141, so as to implement NFC wireless charging.

In example scenario four, the user places the watch shown in fig. 3 face down on the wireless charger. The first NFC antenna 161 receives the sensing information sent by the charger, and the processor 110 determines that the current charging information is charging information according to the sensing information, that is, the wireless charging circuit 141 is determined to be a target circuit. And the sensor 200 will detect the pose information of the watch, so that the processor 110 determines that the watch is facing down according to the pose information detected by the sensor 200, and determines the first NFC antenna 161 as the target antenna. The processor 110 may then control the switching circuit 150 to enable the first NFC antenna 161 to communicate with the wireless charging circuit 141, so as to implement NFC wireless charging.

It can be seen that the wearable device of this disclosed embodiment, no matter first NFC antenna 161 or second NFC antenna 162, can all realize wireless charging and wireless communication's function to need not to carry out the degree of freedom restriction to communication scenes such as the charging of equipment and payment, the user can freely select the operation mode of charging and payment, improves user experience.

In addition, in some embodiments, in consideration of the usage habit of the user in the actual scene, the switching circuit 150 is set to control the first NFC antenna 161 and the wireless communication circuit 142 to be conducted, and the second NFC antenna 162 and the wireless charging circuit 141 to be conducted in the default state.

Therefore, in the first and third example scenarios, the connection mode between the target antenna and the target circuit determined by the processor is the same as the current default state, so that the switching circuit 150 is controlled to maintain the current default connection state. In the above example scenario two and the example scenario four, the connection manner between the target antenna and the target circuit determined by the processor is different from the current default state, so as to control the switching circuit 150 to connect the target antenna and the target circuit. Those skilled in the art can understand and fully implement the present disclosure based on the foregoing, and the detailed description of the present disclosure is omitted.

In some embodiments, the sensor may also be used to obtain location information of a terminal device that establishes a connection with the wearable device, such that the processor determines the target antenna based on the location information of the terminal device. The following description will be made by taking the smart watch shown in fig. 2 and 3 as an example.

The terminal device may be a device of a type such as a smart phone, a tablet, a notebook, etc., and in the embodiments of the present disclosure, the terminal device may establish a connection with the wearable device through a wireless communication module, which includes but is not limited to a communication module such as bluetooth, wiFi, zigbee, etc., which is not limited by the present disclosure.

In addition, the terminal device can wirelessly charge the wearable device. For example, the smart phone has a reverse wireless charging function, and when the wearable device is placed on the smart phone, the smart phone can wirelessly charge the wearable device.

As shown in fig. 4, the wearable device 1000 takes the smart watch shown in fig. 2 and fig. 3 as an example, and the terminal device 2000 has a wireless reverse charging function. The sensor 200 of the wristwatch may employ, for example, a hall sensor, so that the positional information of the terminal device 2000 can be determined from the sensed information of the sensor 200.

It is understood that the position information of the terminal device represents the relative position relationship between the terminal device 2000 and the wearable device 1000, for example, as shown in fig. 4, the wearable device 1000 is located above the terminal device 2000. In other examples, the wearable device 1000 may also be located below the terminal device 2000.

The processor of the watch can determine the relative position relationship between the watch and the terminal equipment according to the position information of the terminal equipment acquired by the sensor 200, so that the target antenna is determined in the first NFC antenna 161 and the second NFC antenna 162, and the target antenna and the target circuit are electrically connected and conducted. Those skilled in the art can understand and fully implement the present disclosure by referring to the foregoing description, and the detailed description of the present disclosure is omitted.

The embodiment of the disclosure also provides a control method of an electronic device, which can be applied to the electronic device described in any of the above embodiments.

As shown in fig. 5, in some embodiments, a control method of an example of the present disclosure includes:

and S510, determining a target antenna from at least two NFC antennas.

In particular, as mentioned above, the device includes at least two NFC antennas, and the device needs to determine a target antenna from the at least two NFC antennas.

The target antenna may refer to an NFC antenna preferentially used in a current usage scenario. Taking the smart watch shown in fig. 3 as an example, when the user wears the watch and uses the NFC wireless communication function to pay for a card swipe, the first NFC antenna 161 is closer to the card swipe machine than the second NFC antenna 162, that is, the antenna efficiency of the first NFC antenna 161 is higher, so that the priority is higher, and the first NFC antenna 161 can be determined as the target antenna. When the user places the watch on the wireless charger with the watch facing upward, the second NFC antenna 162 is closer to the charger than the first NFC antenna 161, that is, the charging efficiency of the second NFC antenna 162 is higher, so that the priority is higher, and the second NFC antenna 162 can be determined as the target antenna.

The process of determining the target antenna is explained in the following embodiments of the present disclosure, and will not be described in detail here.

And S520, determining a target circuit from the wireless charging circuit and the wireless communication circuit based on the operation to be executed currently. Specifically, the operation to be executed currently refers to an operation to be executed by the electronic device in a current scene, for example, in a wireless charging scene, an operation performed by the electronic device to wirelessly charge is the operation to be executed currently. For another example, in an NFC card swiping payment scenario, the payment operation of the NFC card swiping performed by the electronic device is the current operation to be executed.

In some embodiments, the current operation to be performed may be determined based on the sensing information received by any one of the at least two NFC antennas.

Specifically, when a user uses the electronic device to perform operations such as wireless payment and wireless charging, the NFC antenna of the electronic device receives sensing information sent by the external device.

For example, in an example, as shown in fig. 2 and 3, when the user wears the wearable device to perform an NFC card swiping payment operation, when the device is close to the card swiping device, the first NFC antenna 161 and/or the second NFC antenna 162 may receive sensing information sent by the card swiping device.

For example, as shown in fig. 4, when the user places the wearable device on the terminal device for wireless charging, the wearable device is close to the terminal device, and the first NFC antenna 161 and/or the second NFC antenna 162 receive the sensing information sent by the wireless charger.

After receiving the sensing information, the processor may determine whether the operation to be currently performed is a wireless charging operation or a wireless payment operation according to the type of the sensing information.

Specifically, the sensing information sent by the wireless charger is different from the sensing information sent by the card reader. The induction information sent by the wireless charger is charging information, which may include information such as charging protocol, voltage, current, etc.; and the sensed information sent by the card reader is payment information, which may include information such as an encryption protocol. Therefore, the processor can determine the current operation to be executed according to the difference of the induction signals.

After determining that the operation is currently to be performed, the target circuit may be determined from the wireless charging circuit and the wireless communication circuit of the electronic device.

In one example, the wireless communication circuit may be determined to be the target circuit when the processor determines the sensed information to be payment information.

In another example, when the processor determines the sensed information to be charging information, the wireless charging circuit may be determined to be a target circuit.

And S530, controlling the electric connection between the target antenna and the target circuit to be conducted.

As shown in fig. 2, in some embodiments, after determining the target antenna and the target circuit, the processor may send control instructions to control the switching circuit 150 to communicate the target antenna with the target circuit.

In one example, the switching circuit 150 is a control circuit based on MOS transistors, the processor is connected to the control end of each MOS transistor, and the processor controls the MOS transistors to open and close each connection path, so as to communicate the target antenna with the target circuit.

According to the control method, each NFC antenna is communicated with the wireless charging circuit and the wireless communication circuit in a switching mode, so that each NFC antenna can achieve wireless charging or wireless communication, the limitation on the use modes of the charging or payment of equipment and other scenes is small, and the operation of a user is facilitated.

In some implementations, the electronic device of examples of the present disclosure determines the target antenna based on the pose information. For example, as shown in fig. 2, the sensor 200 of the wearable device may employ an accelerometer or a gyroscope, so that the pose information of the wearable device, such as whether the device is currently face-up or back-up, can be detected, and the target antenna can be determined according to the pose information of the device.

As shown in fig. 6, in some embodiments, a control method of an example of the present disclosure includes:

and S610, acquiring pose information of the electronic equipment.

And S620, determining a target antenna from the at least two NFC antennas based on the pose information.

Specifically, the electronic device takes the wearable device shown in fig. 2 and 3 as an example, the sensor of the wearable device detects the pose information of the device, and the sensor can generate the pose information according to the pose change of the wearable device, so that the processor can receive the pose information.

In some embodiments, the correspondence between the pose information and the target antenna may be established in advance. For example, in the smart watch in fig. 3, when the pose information is that the device is right side up, the second NFC antenna 162 may be determined as the target antenna; and when the pose information is the device back side up, the first NFC antenna 161 may be determined as the target antenna. As shown in table one below:

table one:

pose signal	Target antenna
		Right side up	Second NFC antenna
With the front facing downwards	First NFC antenna

In an example scenario, the user places the smart watch on the wireless charger with the front facing up, and at this time, the processor acquires pose information detected by the sensor, where the pose information indicates that the watch is facing up, so that the processor may determine the second NFC antenna 162 as the target antenna according to the correspondence of table one. Because the wrist-watch openly places up, consequently the second NFC antenna 162 that is located drain pan one side is closer to wireless charger, and charging efficiency is also better.

In another example scenario, the user places the smart watch on the wireless charger with the back facing up (i.e., the front facing down), and the processor acquires pose information detected by the sensor, where the pose information indicates that the watch is facing down, so that the processor may determine the first NFC antenna 161 as the target antenna according to the correspondence of table one. Since the watch is placed face down, the first NFC antenna 161 located on one side of the screen is closer to the wireless charger, and the charging efficiency is also better.

In yet another example scenario, a user wears a smart watch to perform NFC swipe payment, and according to the user's usage habits, the user flips over the wrist to bring the watch close to the swipe card reader. At this time, the processor acquires pose information detected by the sensor, where the pose information indicates that the watch is facing down, so that the processor may determine the first NFC antenna 161 as the target antenna according to the correspondence of table one. Since the watch is facing down, the first NFC antenna 161 located on one side of the screen is closer to the card reader and the communication efficiency is better.

According to the control method disclosed by the embodiment of the disclosure, the target antenna is determined by using the pose information detected by the sensor, and the electronic equipment often has the pose sensor, so that the detection can be realized without additionally increasing hardware, the equipment structure is simplified, and the additional cost is not required.

In some embodiments, for a wireless charging scenario, the target antenna may also be determined according to the charging efficiency of each NFC antenna, which is described below with reference to fig. 7.

As shown in fig. 7, in some embodiments, a control method of an example of the present disclosure includes:

and S710, controlling the at least two NFC antennas to be communicated with the wireless charging circuit.

And S720, determining a target antenna from the at least two NFC antennas according to the charging information of each charging circuit.

Specifically, after determining that the wireless charging circuit is the target circuit, the processor may control each NFC antenna to communicate with the wireless charging circuit, so that each NFC antenna may receive the induction signal of the wireless charging.

For example, in the smart watch shown in fig. 3, when the watch is placed on the wireless charger with the front side facing up, the processor may determine that the wireless charging circuit is the target circuit according to the sensing signal. At this time, the processor may control the switching circuit 150 such that the first NFC antenna 161 and the second NFC antenna 162 are both in communication with the wireless charging circuit.

However, it can be understood that since the distances from the wireless charger to the first NFC antenna 161 and the second NFC antenna 162 are different, the attenuation degree of the charging induction signal is different, and the charging efficiency is also different.

Specifically, since the watch is placed right side up, the second NFC antenna 162 on the bottom side of the watch is closer to the wireless charger than the first NFC antenna 161 on the top side of the watch, and therefore the charging efficiency of the second NFC antenna 162 is higher.

Therefore, the processor may obtain charging information of each charging circuit, for example, information including charging voltage, charging current, and the like, and determine that the charging circuit closer to the standard threshold has a higher priority by comparing the charging information of the first NFC antenna 161 and the charging information of the second NFC antenna 162, for example, comparing the charging information with the charging standard threshold, that is, determine that the NFC antenna corresponding to the charging circuit with the higher priority is the target antenna.

In one example, the watch is placed on the wireless charger right side up and the processor may determine the second NFC antenna 162 as the target antenna by comparing the charging information of the charging circuits of the first NFC antenna 161 and the second NFC antenna 162 to determine that the charging information of the charging circuit of the second NFC antenna 162 is closer to the charging criteria threshold.

Therefore, according to the control method disclosed by the example of the disclosure, the target antenna with higher charging efficiency is determined from the plurality of NFC antennas through the comparison of the charging information of each charging circuit, so that the charging efficiency of the device is improved.

In some embodiments, the process of determining the target antenna in the control method according to the embodiments of the present disclosure is not limited to the above example, and may be any other suitable implementation. For example, in the foregoing, the target antenna may be determined based on the position information of the mobile device detected by the sensor, which is not described in detail in this disclosure.

In some embodiments, in consideration of the usage habit of the user in an actual scene, a default communication mode between the NFC antenna and the circuit may be set according to the usage habit of the user. For example, also taking the smart watch in fig. 2 and 3 as an example, the switching circuit 150 may be configured to control the first NFC antenna 161 and the wireless communication circuit 142 to be conducted and the second NFC antenna 162 and the wireless charging circuit 141 to be conducted in a default state.

Thus, after determining the target antenna and the target circuit, the control method of the disclosed example further includes:

and under the condition that the current circuit of the target antenna is different from the target circuit, switching the electrical connection of the target antenna so as to conduct the electrical connection between the target antenna and the target circuit.

Specifically, after the target antenna and the target circuit are determined, if the conduction circuit of the determined target antenna and the determined target circuit is the same as the current default circuit, the current default connection state may be maintained. For example, in the first and third example scenarios, the processor may determine that the target antenna and the target circuit are connected in the same manner as the current default state, so as to control the switching circuit 150 to maintain the current default connected state.

And if the determined conducting circuit of the target antenna and the target circuit is different from the current default circuit, switching the electric connection of the target antenna to conduct the electric connection between the target antenna and the target circuit. For example, in the above example scenario two and the example scenario four, the processor determines that the target antenna and the target circuit are connected in a different manner than the current default state, so as to control the switching circuit 150 to connect the target antenna and the target circuit.

The disclosed embodiments also provide a storage medium storing computer-readable instructions for causing a computer to perform the method according to any one of the preceding embodiments.

It should be understood that the above embodiments are only examples for clearly illustrating the present invention, and are not intended to limit the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications of the present disclosure may be made without departing from the scope of the present disclosure.
