All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that, for the convenience of description, only the parts relevant to the present application are shown in the drawings. The embodiments and features of the embodiments in the present application may be combined with each other without conflict.

As used in this application and the appended claims, the terms "a," "an," "the," and/or "the" are not intended to be inclusive in the singular, but rather are intended to be inclusive in the plural unless the context clearly dictates otherwise. In general, the terms "comprises" and "comprising" merely indicate that steps and elements are included which are explicitly identified, that the steps and elements do not form an exclusive list, and that a method or apparatus may include other steps or elements. An element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in the process, method, article, or apparatus that comprises the element.

In the description of the embodiments herein, "/" means "or" unless otherwise specified, for example, a/B may mean a or B; "and/or" herein is merely an association describing an associated object, and means that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present application, "a plurality" means two or more than two. The terms "first", "second" and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Additionally, flow charts are used herein to illustrate operations performed by systems according to embodiments of the present application. It should be understood that the preceding or following operations are not necessarily performed in the exact order in which they are performed. Rather, the various steps may be processed in reverse order or simultaneously. Meanwhile, other operations may be added to the processes, or a certain step or several steps of operations may be removed from the processes.

Aiming at the technical scheme described in the background technology part, the application initially provides an input method which is carried by an electronic equipment system to realize the input of special symbols, for example, the input method carried by a windows system comprises a set of mathematical symbols, a user can enter a mathematical symbol input interface of the input method to finish the input of a mathematical expression, although the user does not need to memorize character strings corresponding to various mathematical formulas, the learning cost is reduced, and the burden of the vision of the user can not be caused by displaying all the mathematical symbols in a list manner, however, the mode needs the user to memorize different operation systems, enters special instructions of the corresponding input symbol interface, is troublesome and is not suitable for common users, moreover, the input method carried by the system only meets the requirements of the input symbols, can not realize the input of parameters corresponding to the symbols, and still needs the user to switch from the mathematical symbol input interface to a parameter input interface, this also reduces the efficiency of mathematical expression input.

Referring to fig. 1, a schematic flowchart of an optional example of a charging control method provided in the present application is shown, where the method may be applied to a first electronic device, the electronic device has a wireless charging function, such as a user terminal like a smart phone, and the application does not limit a product type of the electronic device, which may depend on a scenario, and as shown in fig. 1, the method may include:

step S11, acquiring first state information of the first electronic device;

for any electronic device with a wireless charging function (denoted as a first electronic device), the application expects that the wireless charging mode can be automatically switched by changing the state of the first electronic device, such as the screen state, the placing posture and the like, and the user does not need to manually enter a setting interface to select the wireless charging mode. Based on the technical concept, the first state information of the first electronic device may be obtained, where the first state information may indicate whether the first electronic device is capable of being used as a charging device, and specific content included in the first state information is not limited in this embodiment of the application.

It can be understood that, for the first state information with different contents, different acquisition or sensing manners may be adopted to acquire the first state information, and specifically, the first state information may be directly acquired by using a device of the first electronic device itself, or corresponding first state information may be acquired according to a parameter sensed by the device, which may be determined according to circumstances, and this application is not listed one by one here.

And step S12, detecting that the first status information satisfies the wireless charging condition, and controlling the first electronic device to enter a wireless reverse charging mode, so that the first electronic device, as a charging device, can deliver power to a device to be charged.

In this embodiment, the above-mentioned charged device may refer to a second electronic device located in a wireless charging radiation range of the first electronic device and in a wireless forward charging mode. That is to say, for two electronic devices having a wireless charging function, when the state information of one electronic device satisfies the wireless charging condition, the wireless charging device can automatically switch to the wireless reverse charging mode as the charging device, and if the state information of the other electronic device does not satisfy the wireless charging condition, the wireless charging device will be in the wireless forward charging mode, and if the other electronic device approaches the charging device and enters the wireless charging radiation range of the charging device, the wireless charging device will be used as the charged device, and the charging device will transmit electric energy to the charged device, that is, the charged device is charged by the charging device.

The wireless charging radiation range of the electronic device with a wireless charging function may be determined according to configuration performance parameters of a wireless charging apparatus of the electronic device, and is generally a spherical space range formed by taking the electronic device as a center and taking a certain distance (which may be referred to as a first distance threshold) as a radius.

It can be understood that, for the first electronic device and the second electronic device, since the first status information content of the first electronic device and the second electronic device changes at any time, the wireless charging mode of the respective devices is affected. Specifically, when it is detected that the first state information of the first electronic device no longer satisfies the wireless charging condition, the wireless charging mode is automatically switched, and if the wireless charging mode is switched from the wireless reverse charging mode to the wireless forward charging mode, the wireless charging mode no longer outputs electric energy, and thus the first electronic device cannot be used as a charging device. Similarly, for the second electronic device, according to the charging control method, in some application scenarios, the second electronic device may also be used as a charging device to charge other devices to be charged, and the implementation process is similar, and is not described in detail herein.

In summary, in the embodiment of the present application, the first electronic device may obtain the first status information that can indicate whether the first electronic device can be used as the charging device, detect that the first status information satisfies the wireless charging condition, automatically control the first electronic device to enter the wireless reverse charging mode, and transmit electric energy to the second electronic device that is located in the wireless charging radiation range of the first electronic device and is in the wireless forward charging mode as the charging device, so as to satisfy the charging requirement of the second electronic device. Therefore, according to the method and the device, the wireless reverse charging mode can be selected without manually entering a setting interface of the first electronic device, the automatic switching control of the wireless charging mode of the first electronic device can be realized, the operation is simple and convenient, and the flexibility of wireless charging control is improved.

Referring to fig. 2, a schematic flow chart of yet another optional example of the charging control method proposed in the present application, where this embodiment may be an optional detailed implementation of the charging control method described in the foregoing embodiment, but is not limited to such a detailed implementation method described in this embodiment, and as shown in fig. 2, the method may include:

step S21, acquiring screen state information and distance sensing information of the first electronic equipment;

in the embodiment of the present application, it is desirable that the wireless charging mode of the electronic device can be automatically adjusted by changing the screen state of the electronic device, that is, automatic switching between the wireless forward charging mode and the wireless reverse charging mode is realized. Therefore, the first state information acquired in the embodiment of the present application may include screen state information of the first electronic device, that is, a parameter that can indicate whether the electronic device is in the first screen state or the second screen state.

The first screen state and the second screen state can be a bright screen state and a black screen state (namely a screen-off state), and if the first screen state is the bright screen state, the second screen state is the black screen state; on the contrary, if the first screen state is the screen off state, the second screen state is the screen on state.

In order to avoid that the first electronic device outputs electric energy without a charged device after the first electronic device serves as a charging device, and the electric energy of the first electronic device is wasted, in the embodiment of the present application, a condition that the first electronic device outputs electric energy to the outside is strictly defined, and in addition to the above-described screen state, a distance between another electronic device and the first electronic device may be considered, that is, whether a charged device exists within a wireless charging radiation range of the first electronic device is considered, and for the definition of the charged device, reference may be made to the description of the corresponding part of the above-described embodiment.

Based on the analysis, the first electronic device may obtain screen state information and distance sensing information in real time or periodically, where the screen state information may include a value of a screen state flag bit capable of indicating a screen state, or a state parameter monitored by a detection device for monitoring a working state of the display component to determine the screen state, and the like; the distance sensing information may be a parameter sensed by a detection device such as a distance sensor provided in the first electronic device, and the content and the respective obtaining manner of the screen state information and the distance sensing information are not limited in the present application, and may be determined according to the situation.

Step S22, determining that the first electronic device is in the first screen state and a second electronic device exists in the wireless charging radiation range of the first electronic device based on the screen state information and the distance sensing information, and controlling the first electronic device to enter a wireless reverse charging mode;

after the above analysis, based on the screen state information acquired by the first electronic device, the current screen state of the screen of the first electronic device can be known, and the current screen state is the first screen state or the second screen state; similarly, by analyzing the acquired distance sensing information, it can be known whether other electronic devices (denoted as second electronic devices) exist within the wireless charging radiation range, and it is determined that the screen of the first electronic device is in the first screen state, and in the case that the second electronic devices exist within the wireless charging radiation range, the wireless charging device is controlled to enter the wireless reverse charging mode by the embodiment, and the first electronic device outputs electric energy to the outside.

The wireless charging device of the first electronic device generally has two wireless charging modes, namely a wireless forward charging mode and a wireless reverse charging mode, and the embodiment of the application can realize automatic switching control between the two wireless charging modes by using detected screen state information and distance sensing information.

Based on the above analysis, referring to the charging application scenario flow diagram shown in fig. 3, taking the first screen state as the bright screen state as an example, when the user wants the first electronic device to be the charging device and the second electronic device to be the charged device, and the first charging device charges the second charging device, the user may illuminate the screen of the first electronic device by means of screen touch or key touch. However, at this time, the second electronic device does not exist in the wireless charging radiation range of the first electronic device, the wireless charging mode is not switched, and the first electronic device is still in the wireless forward charging mode. During the period, if the second electronic device approaches the first electronic device gradually and enters the wireless charging radiation range of the first electronic device in the wireless forward charging mode, the second electronic device will be used as a charged device, and at the same time, the first electronic device will switch to the wireless reverse charging mode as a charging device to start charging the second electronic device.

In step S23, power is transmitted to the second electronic device, so that the second electronic device in the wireless forward charging mode receives the power as a charged device.

After the first electronic device is controlled to automatically switch to the wireless reverse charging mode according to the above manner, the first electronic device outputs electric energy to the outside, and in this case, if the second electronic device located in the wireless charging radiation range of the first electronic device is in the forward charging mode, the second electronic device can be used as a charged device to receive electric energy output by other electronic devices.

Therefore, in this embodiment of the application, the first electronic device automatically switches to the wireless reverse charging mode, and when the first electronic device is used as a charging device, since the second electronic device can be used as a device to be charged at this time, the electric energy output by the first electronic device can be received by the second electronic device, that is, the first electronic device can charge the second electronic device, and details about how to implement the wireless charging are not described after a wireless charging path is established between the two electronic devices having the wireless charging function.

In practical application of the embodiment of the present application, the distance sensing information may be generated after the second device enters the wireless charging radiation range of the first electronic device, and if any second electronic device does not exist in the wireless charging radiation range of the first electronic device, the content of the obtained distance sensing information may be empty, that is, any second electronic device close to the first electronic device is not detected; after the second electronic device enters the wireless charging radiation range of the first electronic device, effective distance sensing information is generated, and the distance sensing information can indicate that the second electronic device exists in the wireless charging radiation range of the first electronic device.

In still other embodiments, the distance sensing range of the first electronic device to the second electronic device may also be greater than the wireless charging radiation range of the first electronic device, that is, in a case that the second electronic device gradually approaches the first electronic device but does not enter the wireless charging radiation range of the first electronic device, the first electronic device may sense, by using the detection device, distance sensing information that can indicate the distance between the first electronic device and the second electronic device, and as the second electronic device gradually approaches the first electronic device, the distance included in the distance sensing information continuously decreases until the distance is smaller than the first distance threshold, it may be considered that the second electronic device enters the wireless charging radiation range of the first electronic device. It can be seen that, in this case, before the second electronic device enters the wireless charging radiation range of the first electronic device, the distance sensing information including the distance between the first electronic device and the second electronic device can be obtained.

It should be noted that, the obtaining scenario and the content included in the foregoing exemplary sensing information are not limited to the contents described in the foregoing embodiments, and may be determined as the case may be.

In summary, in the embodiment of the present application, the first electronic device determines that the first electronic device is in the first screen state by acquiring the screen state information and the distance sensing information of the first electronic device, and under the condition that the second electronic device exists in the wireless charging radiation range of the first electronic device, the first electronic device is automatically controlled to switch to the wireless reverse charging mode, so that the first electronic device can be used as a charging device to transmit electric energy to the second electronic device serving as a charged device, and a user does not need to enter a setting interface of the first electronic device to manually select the wireless reverse charging mode of the first electronic device, so that flexibility and convenience of wireless charging mode switching control of the electronic devices are improved, and convenience of mutual charging between electronic devices having a wireless charging function is improved.

Referring to fig. 4, which is a schematic flowchart of a further optional example of the charging control method proposed in the present application, this embodiment may be a further optional detailed implementation of the charging control method described in the foregoing embodiment, and is mainly different from the triggering implementation of the switching control of the wireless reverse charging mode of the first electronic device described in the foregoing detailed embodiment, as shown in fig. 4, the method may include:

step S31, acquiring screen state information of the first electronic equipment;

step S32, determining that the first electronic device is in the first screen state based on the screen state information, and controlling the first electronic device to enter a wireless reverse charging mode;

regarding the process of acquiring the screen state information of the first electronic device and the implementation process of determining the current screen state of the first electronic device based on the screen state information, reference may be made to the description of the corresponding parts in the foregoing embodiments, which is not repeated in this embodiment.

It can be seen that, referring to the schematic flow chart of the charging application scenario shown in fig. 5, different from the detailed embodiment described above, the first electronic device is required to be in the first screen state, and only when the second electronic device exists in the wireless charging radiation range of the first electronic device, the first electronic device is automatically switched to the wireless reverse charging mode.

In some embodiments, since the first electronic device may output the electric energy after entering the wireless reverse charging mode, in order to reduce the electric energy waste of the first electronic device, after determining to enter the wireless reverse charging mode, the first electronic device may output corresponding charging prompt information to remind a user that the first electronic device may be used as a charging device at the moment, and a second electronic device that needs to be charged may be close to the first electronic device, and the first electronic device charges the second electronic device.

The charging prompt message may be output in any one or a combination of a plurality of output modes such as a language playing mode, a text output mode, a buzzer sound, and the like.

Step S33, obtaining distance sensing information of the first electronic device;

step S34, detecting whether the second electronic device enters the wireless charging radiation range of the first electronic device within the first time period based on the distance sensing information; if yes, go to step S35; if not, go to step S36;

as described above, when it is determined that the first electronic device enters the wireless reverse charging mode, it may be determined whether a second electronic device exists within the wireless radiation range thereof through distance sensing information sensed by the detection device, in this process, in order to avoid that the first electronic device outputs electric energy for a long time, but the output electric energy is not received by other devices and causes electric energy waste, a time duration for allowing the electronic device to output electric energy, but the electric energy is not received by other devices, may be preset and recorded as a first time duration, so that, when the first electronic device starts to switch to the wireless reverse charging mode for timing, if it is still detected that any second electronic device enters the wireless charging radiation range of the first electronic device within the first time duration, the first electronic device ends the wireless reverse charging mode and does not continue to output electric energy; on the contrary, if it is detected that at least one second electronic device enters the wireless charging radiation range of the first electronic device within the first time period and the second electronic device in the wireless forward charging mode exists, the electric energy output by the first electronic device is transmitted to the second electronic device, so that the electric energy waste of the first electronic device is reduced.

It should be noted that, the specific value of the first duration is not limited in the present application, and may be determined according to the circumstances, and the user may also customize the first duration according to the actual requirement, and the specific implementation process is not described in detail. As to how to determine whether the implementation process of the second electronic device exists in the wireless charging radiation range of the first electronic device based on the distance sensing information, reference may be made to the description of the corresponding parts of the above embodiments, which is not described herein again.

Step S35, transmitting power to the second electronic device in the wireless forward charging mode;

and step S36, controlling the first electronic device to switch from the wireless reverse charging mode to the wireless forward charging mode, and stopping outputting the electric energy.

As can be seen from the above analysis, at any time within a first duration after the first electronic device enters the wireless reverse charging mode, if it is determined that the second electronic device enters the wireless charging radiation range of the first electronic device based on the distance sensing information acquired at the time, and the second electronic device is in the wireless forward charging mode, the second electronic device will receive the electric energy output by the first electronic device.

Of course, if the second electronic device is also in the wireless reverse charging mode, both the second electronic device and the first electronic device may be used as charging devices to charge other electronic devices (denoted as third electronic devices); or according to a preset control strategy, selecting one electronic device from the first electronic device and the second electronic device as a charging device, and using the other electronic device as a charged device, wherein at this time, the wireless charging mode of the charged device is also automatically switched from the wireless reverse charging mode to the wireless forward charging mode, so as to implement wireless charging between the two electronic devices, and a specific implementation process of the present application is not described in detail herein.

In summary, in the embodiment of the present application, with reference to the schematic flow chart of the charging application scenario shown in fig. 5, when the first electronic device is required to be used as a charging device to charge other electronic devices, the screen state of the first electronic device may be controlled to enter the first screen state, for example, the screen is turned on, the first electronic device is automatically controlled to be directly switched to the wireless reverse charging mode, the output of the electric energy is started, the wireless reverse charging mode is not required to be manually selected by entering the first electronic device setting interface, and the operation is very simple; then, based on the acquired distance sensing information, determining that a second electronic device enters a wireless charging radiation range of the first electronic device within a first time period, wherein the second electronic device is used as a charged device and can receive electric energy output by the first electronic device, namely the first electronic device charges the second electronic device; if any second electronic device does not enter the wireless charging radiation range of the first electronic device within the first duration, the electric energy output by the first electronic device is released to the environment and is not wasted, and the electric energy is not received by any second electronic device, at this time, the first electronic device is controlled to be switched from the wireless reverse charging mode to the wireless normal charging mode, the electric energy output is stopped, and the electric energy waste of the first electronic device is reduced.

Referring to fig. 6, which is a schematic flow chart of yet another optional example of the charging control method proposed in the present application, this embodiment may be a further optional detailed implementation manner of the charging control method described in the foregoing embodiment, which is mainly different from the triggering implementation manner of the switching control of the wireless reverse charging mode of the first electronic device described in the foregoing two detailed embodiments, and this embodiment proposes that the automatic switching control of the wireless charging mode of the first electronic device may be implemented according to a posture change of the first electronic device, specifically, as shown in fig. 6, the method may include:

step S41, acquiring motion attitude information of the first electronic equipment;

referring to the schematic flow chart of the charging application scenario shown in fig. 7, since the embodiment of the present application desires to implement automatic switching control of the wireless charging mode according to the posture change of the first electronic device. Therefore, the motion attitude information of the first electronic device can be obtained by utilizing the parameters sensed by the detection device of the first electronic device, such as a gyroscope, a gravity sensor, an angle sensor, a turnover sensor and the like, so that the attitude change of the first electronic device can be further determined.

It should be noted that, the content of the operation posture information of the first electronic device and the sensing manner thereof are not limited in the present application, and are not limited to the above-mentioned detection devices, which may be determined as the case may be.

Step S42, based on the movement posture information, determining that the first electronic equipment generates a first turnover angle relative to the specific posture position, and the first turnover angle reaches the specific turnover angle, and controlling the first electronic equipment to enter a wireless reverse charging mode;

in the embodiment of the present application, the specific gesture position may be a reference gesture position used to detect whether the electronic device is turned over and from what gesture position to what gesture position, and a general gesture position of the electronic device may be defined as the specific gesture position, as shown in fig. 7, the specific gesture position may refer to a gesture position where the electronic device is placed on a plane and a screen is facing upwards (i.e., a user can view screen display content), but is not limited to the specific gesture position shown in fig. 7.

As shown in the schematic flow chart of the charging application scenario shown in fig. 7, a user wants to use the first electronic device as a charging device, based on the charging control technology concept provided in this embodiment of the application, the screen of the first electronic device may be turned downward, that is, from a specific posture position where the screen of the first electronic device is placed upward, the first electronic device may be turned leftward or rightward (fig. 7 only shows that the screen of the first electronic device is turned leftward, and the turning process to the right side is similar and is not described in detail), so that the screen of the first electronic device faces downward and the back case faces upward, so that the device to be charged may be directly placed on the back case of the first electronic device for wireless charging.

In the process that the first electronic device is turned in the direction shown in fig. 7, the first turning angle generated with respect to the specific posture position is gradually increased until the specific turning angle is reached (for example, the actual turning direction is the forward direction, the specific turning angle may be 180 degrees, and the like), that is, the screen of the first electronic device faces downward (for example, the state shown in the third drawing on the left side of the first row in fig. 7), and the first electronic device may control the wireless charging device to automatically switch to the wireless reverse charging mode, and start outputting electric energy to the outside.

In a possible implementation manner, the first electronic device determines that the first electronic device generates a first flip angle relative to a specific attitude position, and when the first flip angle reaches a specific flip angle, the first electronic device may control the wireless charging mode to switch from the wireless forward charging mode to the wireless reverse charging mode in response to a wireless charging switching instruction, but is not limited to this wireless charging mode switching control implementation manner.

In some embodiments provided by the application, in the process of detecting the turning of the first electronic device, any one surface of the first electronic device may be specifically selected as a turning reference surface, such as a surface where a screen is located or any one side surface, and in the process of detecting the motion posture information, the automatic switching control of the wireless charging mode may be implemented by detecting a first turning angle of the turning reference surface. In a similar way, the turning condition of the first electronic device can be determined by detecting the first turning angle of a certain side edge (i.e. the turning reference axis) of the first electronic device relative to the specific posture position, so as to realize automatic switching control of the wireless charging mode of the first electronic device, and the like.

In step S43, the power is output within the wireless charging radiation range, so that the second electronic device in the wireless forward charging mode receives the power within the wireless charging radiation range.

After the wireless charging device of the first electronic device is switched to the wireless reverse charging mode, the wireless charging device of the first electronic device can output electric energy to the outside as the charging device, for example, the transmitting coil transmits the electric energy in the wireless charging radiation range, so that the charged device entering the wireless charging radiation range can receive the electric energy and charge the energy storage device of the charged device.

The charged device entering the wireless charging radiation range of the first electronic device is the second electronic device in the wireless forward charging mode, that is, at this time, a coil in the wireless charging device of the second electronic device will be used as a receiving coil to receive the electric energy transmitted by the transmitting coil of the first electronic device, and the electric energy is transmitted to the energy storage device of the second electronic device after the ac-dc conversion processing of the received electric energy.

In combination with the above detailed description of each detailed embodiment, the second electronic device in the wireless forward charging mode, that is, the charged device, is an electronic device in the second screen state and/or the specific posture position, and may specifically be determined according to the content of the preconfigured wireless charging condition for implementing the wireless charging mode switching of the electronic device: if the automatic switching control between the two wireless charging modes of the electronic equipment is realized according to the change of the screen state, the charged equipment can refer to the electronic equipment in a second screen state (such as a black screen state); if automatic switching control between two wireless charging modes of the electronic device is realized according to the movement posture change of the electronic device (specifically, the screen turning condition), the charged device may refer to the electronic device in a specific posture position, such as the electronic device with the screen facing upward.

In some embodiments, the present application may also combine the wireless charging condition contents described in the detailed embodiments to comprehensively implement automatic switching control between two wireless charging modes of the electronic device, for example, the content of the wireless charging condition is determined by combining two or three kinds of information, such as the screen state information, the motion posture information, and the distance sensing information, to determine that the electronic device is in the wireless forward charging mode or the wireless reverse charging mode, and the specific implementation process of this embodiment is not described in detail.

In summary, in the embodiment of the present application, in a scenario that the first electronic device is required to charge the second electronic device, the first electronic device may be turned over relative to a specific posture position, and when a first turning angle generated by the first electronic device reaches a specific turning angle, the wireless charging device is automatically controlled to switch to the wireless reverse charging mode, and electric energy may be output within a wireless charging radiation range of the wireless reverse charging device.

In some embodiments proposed in the present application, based on the charging control method described in the foregoing embodiments, in a process in which the first electronic device serves as a charging device and is capable of delivering power to a device to be charged, as described in the foregoing embodiments, power output by the first electronic device within a wireless charging radiation range of the first electronic device can be received by the second electronic device in a wireless forward charging mode as the device to be charged, that is, charging of the second electronic device is achieved by the first electronic device.

However, if the first electronic device enters the second electronic device in the wireless charging radiation range during the period of the electric energy output by the first electronic device in the wireless charging radiation range, the first electronic device is also in the wireless reverse charging mode, that is, both the first electronic device and the second electronic device are in the wireless reverse charging mode and can be used as charging devices, in this case, the second electronic device may refuse to receive the electric energy output by the first electronic device, and similarly, the first electronic device may also refuse to receive the electric energy output by the second electronic device.

In another possible implementation manner, in order to avoid waste of electric energy output by each of the first electronic device and the second electronic device, the present application may also select one electronic device as the charging device and the other electronic device as the device to be charged according to a certain control strategy, so as to implement wireless charging between the two electronic devices.

Specifically, referring to a signaling flow diagram of another optional example of the charging control method provided in this application shown in fig. 8, in this embodiment, a processing procedure after the first electronic device and the second electronic device are switched to the wireless reverse charging mode may be mainly described according to the charging control method described in the above embodiment, and as to how the electronic device automatically switches from the wireless forward charging mode to the wireless reverse charging mode, reference may be made to descriptions of corresponding parts in the above embodiment, which is not described in detail in this embodiment.

As shown in fig. 8, the charging control method provided in this embodiment may further include:

step S51, the first electronic device outputs electric energy in the wireless charging radiation range and refuses to receive the electric energy output by the second electronic device when being in the wireless reverse charging mode;

step S52, the second electronic device outputs electric energy in the wireless charging radiation range and refuses to receive the electric energy output by the first electronic device when being in the wireless reverse charging mode;

as to how the first electronic device and the second electronic device enter the wireless reverse charging mode, the implementation process of outputting electric energy within the respective wireless charging radiation range may refer to the description of the corresponding parts of the above embodiments, which is not described herein again.

In the embodiment of the application, the first electronic device and the second electronic device are both in the wireless reverse charging mode at the same time, and the coils in the respective wireless charging devices are both used as transmitting coils, so that in this case, the electric energy output by the two electronic devices is directly released into the environment, which causes electric energy waste. Of course, if there is a third electronic device in the wireless forward charging mode and the third electronic device enters the wireless charging radiation range of the first electronic device and/or the second electronic device, the third electronic device may serve as a charged device to receive the electric energy output by the first electronic device and the second electronic device.

Step S53, the first electronic device establishes electromagnetic communication with the second electronic device;

step S54, the first electronic equipment obtains a first residual capacity of the self energy storage device;

step S55, the first electronic device obtains a second remaining capacity of the energy storage device of the second electronic device through the electromagnetic communication, and sends the first remaining capacity to the second electronic device;

in the embodiment of the present application, the wireless charging apparatus in the first electronic device and the second electronic device generally includes a coil for receiving or transmitting an electromagnetic signal, and when both of the two electronic devices are in the wireless reverse charging mode, the coil in the respective wireless charging apparatus is energized and will be used as a transmitting coil to output electric energy, and a wireless charging path cannot be formed.

Therefore, in the embodiment of the present application, electromagnetic communication between the first electronic device and the second electronic device may be established by using electromagnetic wave signals respectively transmitted by the first electronic device and the second electronic device, so as to implement data interaction between the first electronic device and the second electronic device through the electromagnetic communication, for example, interaction of the remaining power of the respective energy storage device enables the first electronic device and the second electronic device to know the respective remaining power of the two electronic devices.

Step S56, the first electronic device detects that the second remaining capacity is smaller than the first remaining capacity, and maintains the wireless reverse charging mode;

step S57, the second electronic device switches from the wireless reverse charging mode to the wireless forward charging mode when detecting that the first remaining capacity is greater than the second remaining capacity;

step S58, the first electronic device transmits power to the second electronic device;

according to the mode, the first electronic device and the second electronic device can interact with the residual electric quantity of the respective energy storage device through electromagnetic communication, then, no matter which electronic device is low in residual electric quantity, the first electronic device and the second electronic device can compare the residual electric quantity of the first electronic device with the residual electric quantity of the energy storage device of the other electronic device to determine which electronic device is low in residual electric quantity, one electronic device with low residual electric quantity is used as a charged device, and the wireless reverse charging mode of the wireless charging device is controlled to be switched to the wireless forward charging mode; and the other electronic equipment with more residual capacity is used as a charging equipment, and the wireless charging mode of the electronic equipment can be kept unchanged temporarily.

In this embodiment, a scenario that the second remaining capacity of the energy storage device of the second electronic device is smaller than the first remaining capacity of the energy storage device of the first electronic device is taken as an example for explanation, according to the analysis process, the first electronic device may serve as a charging device, the second electronic device serves as a charged device, and it is necessary to control the wireless charging mode to switch to the wireless forward charging mode, so that the coil of the wireless charging device serves as a receiving coil to receive the electric energy output by the transmitting coil of the first electronic device, that is, the first electronic device charges the second electronic device. For the situation that the second remaining capacity of the energy storage device of the second electronic device is greater than the first remaining capacity of the energy storage device of the first electronic device, the control process is similar, and detailed description is not given in this application.

In still other embodiments provided by the present application, under the condition that the first remaining power and the second remaining power are different, it may further be detected whether a power difference between the first remaining power and the second remaining power is greater than a first power threshold (a specific value thereof is not limited, and may be determined as the case may be), that is, whether a remaining power difference between the two electronic devices is greater is detected, and if the difference is greater, that is, the power difference is greater than the first power threshold, one of the two electronic devices is selected as a charged device according to the above-mentioned manner, and the wireless charging mode is switched.

On the contrary, if the difference between the remaining electric quantities of the two electronic devices is small, that is, the difference between the electric quantities is smaller than or equal to the first electric quantity threshold, the electronic devices may be selected not to be charged with each other, and both the electronic devices are directly switched to the wireless forward charging mode to stop outputting the electric energy, or the difference between the respective remaining electric quantities and the full-rated electric quantity (that is, the first electric storage threshold) is detected, and if the difference is smaller than the second electric quantity threshold, the two electronic devices may be considered to be temporarily not required to be charged, and other charged devices are not detected directly or after the first time period, and the corresponding electronic devices are controlled to be switched to the wireless forward; if the difference between the remaining capacity and the full capacity is greater than the third capacity threshold (which is greater than the second capacity threshold, and the specific value is not limited), it may be considered that both the two electronic devices may have insufficient capacity, and may output corresponding prompt information to be charged to remind the user to charge the electronic device by using direct charging or other wireless charging devices.

In still other embodiments provided by the present application, for the detection of the first remaining power and the second remaining power, after the first electronic device or the second electronic device completes the detection, the detection result may be sent to another electronic device through electromagnetic communication, and the another electronic device determines whether to switch the wireless charging mode based on the detection result directly, so that it is not necessary for both electronic devices to perform comparison detection of the remaining power.

Step S59, the second electronic device detects that the amount of power stored in the power storage device reaches a first power storage threshold value, and generates a power full message;

step S510, the second electronic device sends the information of full charge to the first electronic device;

in step S511, the first electronic device switches from the wireless reverse charging mode to the wireless forward charging mode in response to the power fullness message, and stops outputting the electric power.

In the process of wirelessly charging another electronic device by one electronic device described in the above embodiments, it may be determined whether the charging device is to continue to supply electric energy to the charged device by detecting whether the charge capacity of the charge storage device of the charged device reaches the first charge threshold, that is, whether the charge storage device is fully charged.

The present application only describes an implementation manner of detecting the stored electric energy of the charged device by itself, but is not limited to such a detection implementation manner, and the present application does not limit the content of the electric energy full message and the output manner thereof.

It should be noted that, in this embodiment, if the number of the second electronic devices in the above state is multiple, that is, one first electronic device charges multiple second electronic devices, after determining that the stored capacities of the multiple second electronic devices all reach the corresponding first stored capacity threshold, that is, after the first electronic device receives the full charge message fed back by each of the multiple second electronic devices, the wireless reverse charging mode is switched to the wireless forward charging mode, and the output of the electric energy is stopped; if the storage capacity of at least one second electronic device does not reach the first storage threshold value in the charging process, namely the first electronic device receives the full charge information fed back by part of the second electronic devices, the first electronic device can continue to output electric energy until the full charge information fed back by each second electronic device is received, and then the first electronic device is controlled to be switched from the wireless reverse charging mode to the wireless forward charging mode.

It can be seen that, in this application practical application, first electronic equipment carries out wireless charging process for a plurality of second electronic equipment, can be after confirming that these a plurality of second electronic equipment all are full of the electricity, and first electronic equipment automatic switch-over wireless charging mode stops the output electric energy, avoids the electric energy extravagant. In still other embodiments, the first electronic device may also determine that a specific number (which is smaller than the number of the second electronic devices receiving the power) of the second electronic devices is fully charged in the above manner, and the first electronic device automatically switches the wireless charging mode to stop outputting the power, as the case may be, which is not described in detail herein.

In summary, when two electronic devices are both in a wireless reverse charging mode and are located within a wireless charging radiation range of the other electronic device, the two electronic devices will both output electric energy within their respective wireless charging radiation range and refuse to receive electric energy output by the other electronic device, in order to reduce electric energy waste, the embodiments of the present application utilize electromagnetic communication between the two electronic devices to interact with the remaining amount of the respective energy storage device, determine a second electronic device with less remaining amount as a charged device, control its wireless charging device to switch from the wireless reverse charging mode to the wireless forward charging mode, stop outputting electric energy, and still use the first electronic device with more remaining amount as a charging device, maintain the wireless reverse charging mode unchanged, so that electric energy output by the first electronic device can be received by the second electronic device, and the waste of electric energy is reduced.

After that, when it is detected that the power storage amount of the second electronic device reaches the first power storage threshold, the first electronic device may switch from the current wireless reverse charging mode to the wireless forward charging mode in response to the power full message for the second electronic device, and stop charging, so as to avoid power waste caused by no electronic device receiving power. In addition, in the whole charging control process between the electronic devices, a user does not need to select a wireless charging mode, and the flexibility and the convenience of the charging control of the electronic devices are improved.

In still other embodiments provided in the present application, in the charging control process described in the above embodiments, when the first electronic device serves as a charging device and supplies power to a device to be charged, if there are two electronic devices both in the wireless reverse charging mode, in addition to the implementation method that can determine which electronic device is the charging device and which electronic device is the device to be charged according to the remaining electric quantities of the two electronic devices in the manner described above, the present application may also determine the charging device and the device to be charged according to the relative position relationship of the two electronic devices.

Specifically, after the first electronic device and the second electronic device are both in the wireless reverse charging mode and electromagnetic communication between the first electronic device and the second electronic device is established, the first electronic device and the second electronic device can both obtain a relative position relationship between the first electronic device and the second electronic device through the electromagnetic communication, so that according to the relative position relationship, the first electronic device or the second electronic device is determined to be the charging device, the wireless reverse charging mode is maintained unchanged, the other electronic device of the two electronic devices is controlled, the wireless reverse charging mode is switched to the wireless forward charging mode, and the wireless reverse charging mode is used as the charged device to receive electric energy transmitted by the charging device.

For example, if the first electronic device and the second electronic device are both in the first screen state, such as the bright screen state, the wireless charging devices of the two electronic devices are both in the wireless reverse charging mode, and if the second electronic device is placed above a certain surface of the first electronic device, the first electronic device and the second electronic device are in the vertical structural relationship, which may be determined by attribute information such as the strength and the direction of an electromagnetic signal received in the electromagnetic communication process, but is not limited to this relative positional relationship and the detection implementation method thereof, and this application is only described with this as an example.

In this case, the first electronic device may be determined as a charging device, the second electronic device may be determined as a charged device, the wireless charging mode of the first electronic device as the charging device may be maintained, and the second electronic device as the charged device may control its wireless charging apparatus to automatically switch from the wireless reverse charging mode currently located to the wireless forward charging mode, and the specific implementation process is not described in detail, so that the first electronic device charges the second electronic device. The charging control process for the relative position relationship of other contents is similar, and the detailed description is not given in this application.

In still other embodiments provided in the present application, based on the description of the content of the wireless charging condition described in the foregoing embodiments in the process of delivering the electric energy from the first electronic device as the charging device to the device to be charged, the wireless charging condition is recorded as a condition for determining whether the electronic device can be used as the charging device, and specifically, the description may include, but is not limited to, at least one of the following conditions: the electronic equipment is in a first screen state; the electronic equipment is in a first screen state, and charged equipment exists in a wireless charging radiation range of the electronic equipment; the electronic equipment generates a first turning angle relative to the specific posture position, and the first turning angle reaches a specific turning angle and the like.

Based on this, in the process that the first electronic device is used as a charging device to charge a device to be charged, it is determined that the first electronic device no longer satisfies the corresponding wireless charging condition according to the first state information obtained in real time, and if the duration that the device to be charged leaves the wireless charging radiation range of the first electronic device reaches a second duration (which may be the same as or different from the first duration, and depending on the circumstances, the present application does not limit the value), that is, in the wireless charging radiation range of the first electronic device, any device to be charged is not detected within the second duration.

In still other embodiments, in the detecting process that the wireless charging condition is not satisfied, the method may further include detecting that the first electronic device switches from the first screen state to the second screen state, such as changes to a black screen state, and may also directly control the first electronic device to switch from the wireless reverse charging mode to the wireless forward charging mode; or under the condition that the two wireless charging conditions are not met, the first electronic equipment is controlled to switch the wireless charging mode.

In still other embodiments, when it is detected that the first electronic device is turned to a specific posture position, for example, the first electronic device is returned to the state with the screen facing upward, the specific implementation process may be determined by combining the turning angle generated by the first electronic device with the related description of the above turning embodiment, and the implementation process is not described in detail in this application. Under the condition, the first electronic equipment is controlled to finish automatic switching of the wireless charging mode, namely, the wireless reverse charging mode is switched to the wireless forward charging mode, and the electric energy output is stopped. Or, in combination with the one or two wireless charging conditions, when it is determined that the plurality of wireless charging conditions are not satisfied, the first electronic device is controlled to complete the automatic switching of the wireless charging mode, and a specific implementation process of the method is not described in detail in this application.

Based on the above analysis, referring to the schematic view of the charging application scenario shown in fig. 9, in the process of charging the second electronic device by the first electronic device, the second electronic device as the device to be charged may be switched from the second screen state to the first screen state, which does not affect the charging of the second electronic device by the first electronic device, that is, in the wireless charging process, the user may normally use the second electronic device. And then, according to the mode, after the second electronic device is determined to be fully charged or the second electronic device leaves the wireless sufficient radiation range of the first electronic device for a second time, controlling the first electronic device to stop outputting the electric energy.

In the charging process, the first electronic device may maintain the first screen state, and may also switch to the second screen state, and specifically, the screen state of the first electronic device may be determined to change according to a preconfigured charging stop condition (which may include, but is not limited to, the content of the wireless charging condition not being satisfied as described in the above embodiment), and whether the charging process is interrupted or not may be determined. That is, if the screen state of the first electronic device is configured in advance to be switched from the first screen state to the second screen state, and the output of the power is stopped, then, in the process of charging the second electronic device by the first electronic device in fig. 9, the screen state of the first electronic device is maintained in the first screen state; if the screen state of the first electronic device does not affect charging, the first electronic device can also be switched to a black screen state in the charging process.

In addition, in the process of charging the second electronic device by the first electronic device, if the user moves the second electronic device away from the first electronic device until the user moves away from the wireless charging radiation range of the first electronic device (e.g., the spatial range shown by the dotted circle in fig. 9), after a second period of time, the second electronic device still does not return to the wireless charging radiation range of the first electronic device again, the first electronic device stops charging the second electronic device, and at this time, if no other charged device exists, the first electronic device directly switches to the wireless forward charging mode, and stops outputting the electric energy.

It can be understood that if the second electronic device leaves the wireless charging radiation range of the first electronic device, but enters the wireless charging radiation range of the first electronic device again within the second time period, the first electronic device will continue to charge the second electronic device, and in the absence of other charged devices, the first electronic device is always in the wireless reverse charging mode in the process. Therefore, when a user mistakenly keeps the second electronic device away from the first electronic device and is in a scene of being close to the first electronic device, the electric energy output control of the first electronic device cannot be interrupted, and the first electronic device is prevented from frequently switching the wireless charging mode.

When the second electronic device leaves the wireless charging radiation range of the first electronic device, corresponding prompt information can be output to remind a user that the first electronic device is interrupted in charging for the second electronic device currently, so that the user still needs to charge the second electronic device after receiving the prompt, and the second electronic device is close to the first electronic device again.

In still other embodiments, in the charging control method described in each of the above embodiments, in the above manner, during the wireless charging process performed by the first electronic device for the second electronic device, the third electronic device may perform wired charging for the first electronic device, that is, the wireless charging process and the wired charging process of the first electronic device may be performed simultaneously without interfering with each other; of course, according to actual requirements, the charging manner of the electronic device may also be constrained, for example, one of a wireless charging manner and a wired charging manner is selected to be executed, where the wireless charging manner may be that the first electronic device wirelessly charges the second electronic device.
