Please refer to FIG. 1 . FIG. 1 is a first schematic flowchart of a coil switching method provided by an embodiment of the present application. The coil switching method may be applied to an electronic device, and the electronic device may include a receiving coil assembly, and the receiving coil assembly may include a low-power receiving coil, a medium-power receiving coil, and a high-power receiving coil. The flow of the coil switching method may include:

In 101, when wireless charging is performed, the temperature of the electronic device is obtained.

With the continuous development of technology, more and more electronic devices use wireless charging. Wireless charging refers to the transfer of electrical energy through non-conductive substances. In practical applications, wireless charging usually refers to the transfer of electrical energy through a certain spatial distance. There are four main ways to realize wireless charging technology: electromagnetic induction, magnetic resonance, radio wave, and electric field coupling. However, in the related art, the temperature of the electronic device is relatively high during the wireless charging process.

In 101 of this embodiment of the present application, for example, in the process of wireless charging, the electronic device may acquire its own temperature.

After acquiring the temperature of the electronic device, the electronic device can detect whether the temperature is greater than or equal to a preset temperature threshold.

If it is detected that the temperature is lower than the preset temperature threshold, it can be considered that the temperature of the electronic device is low. At this time, the electronic device may perform other operations.

If it is detected that the temperature is greater than or equal to the preset temperature threshold, enter 102 .

In 102, if the temperature of the electronic device is greater than or equal to a preset temperature threshold, it is determined whether the currently used receiving coil is a low-power receiving coil.

For example, if the electronic device detects that its temperature is greater than or equal to the preset temperature threshold, it can be considered that the temperature of the electronic device is high at this time. In this case, the electronic device can determine whether the currently used receiving coil is a low-power receiving coil.

If the electronic device determines that the currently used receiving coil is a low-power receiving coil, the electronic device may perform other operations. For example, electronic devices can continue to use low-power receiving coils for wireless charging.

If the electronic device determines that the currently used receiving coil is not a low-power receiving coil, then go to 103 .

In 103, if the currently used receiving coil is not a low-power receiving coil, the receiving coil is switched, wherein if the currently used high-power receiving coil is switched to a non-high-power receiving coil, if the currently used is a medium-power receiving coil The coil then switches to the low power receiver coil.

For example, if the electronic device determines that the currently used receiving coil is not a low-power receiving coil, but a high-power receiving coil or a medium-power receiving coil, the electronic device can switch the receiving coil. Wherein, if a high-power receiving coil is currently used, the electronic device can switch from a high-power receiving coil to a non-high-power receiving coil, for example, switching to a medium-power receiving coil or a low-power receiving coil. If the medium power receiving coil is currently used, the electronic device can switch from the medium power receiving coil to the low power receiving coil. After that, the electronic device can be wirelessly charged using the switched receiver coil.

It can be understood that, in this embodiment, the receiving coil of the electronic device includes a low-power receiving coil, a medium-power receiving coil, and a high-power receiving coil. During wireless charging, if the temperature of the electronic device is greater than or equal to a preset temperature threshold, and the receiver coil used by the electronic device is not a low-power receiver coil, the electronic device can switch from a high-power receiver coil to a non-high-power receiver coil, or Switch from the medium power receiving coil to the low power receiving coil, thereby reducing the charging power of the terminal. After the charging power of the electronic device is reduced, the temperature thereof can also be lowered, thereby effectively solving the problem of excessive temperature of the electronic device during the wireless charging process.

Please refer to FIG. 2 , which is a schematic flowchart of a second coil switching method provided by an embodiment of the present application. The coil switching method may be applied to an electronic device, and the electronic device may include a receiving coil assembly, and the receiving coil assembly may include a low-power receiving coil, a medium-power receiving coil, and a high-power receiving coil. The flow of the coil switching method may include:

In 201, during wireless charging, the electronic device detects whether a foreground application is running.

For example, in the process of wireless charging, the electronic device can detect whether there is a foreground application running.

It should be noted that the foreground application refers to an application currently running on the electronic device, and the application is not an application running in the background. For example, if the electronic device is currently playing a video through a video application, the video application is the foreground application.

If it is detected that no foreground application is currently running, the electronic device may perform other operations.

If it is detected that a foreground application is currently running, enter 202 .

In 202, if there is a foreground application running, the electronic device obtains its temperature.

For example, if the electronic device detects that the user is currently using video application A to play a video, the electronic device may determine that a foreground application is currently running, and at this time, the electronic device may obtain its own temperature.

For example, in one embodiment, the electronic device may acquire its own temperature at preset time intervals. Alternatively, the electronic device can also acquire its own temperature in real time.

After acquiring its own temperature, the electronic device can detect whether the temperature is greater than or equal to a preset temperature threshold.

If it is detected that the temperature is lower than the preset temperature threshold, it can be considered that the temperature of the electronic device is still low, and the electronic device can perform other operations.

If it is detected that the temperature is greater than or equal to the preset temperature threshold, go to 203 .

In 203, if the temperature is greater than or equal to a preset temperature threshold, the electronic device determines whether the currently used receiving coil is a low-power receiving coil.

For example, if the electronic device detects that its temperature is greater than or equal to a preset temperature threshold, the electronic device can determine whether the currently used receiving coil is a low-power receiving coil.

If it is determined that the currently used receiving coil is not a low-power receiving coil, enter 204 .

If it is determined that the currently used receiving coil is a low-power receiving coil, go to 207 .

In 204, if the currently used receiving coil is not a low-power receiving coil, the electronic device obtains a temperature difference between its temperature and a preset temperature threshold.

For example, if the electronic device determines that the currently used receiving coil is not a low-power receiving coil, but a high-power receiving coil or a medium-power receiving coil, the electronic device can obtain the temperature difference between its temperature and a preset temperature threshold. After that, the electronic device can detect whether the temperature difference is greater than or equal to the preset temperature difference value.

If it is detected that the temperature difference is greater than or equal to the preset temperature difference value, go to 205 .

If it is detected that the temperature difference is less than the preset temperature difference value, then go to 206 .

In 205, if the temperature difference is greater than or equal to the preset temperature difference value, the electronic device switches to the low-power receiving coil.

For example, if the electronic device detects that the temperature difference between its temperature and the preset temperature threshold value is greater than or equal to the preset temperature difference value, it may be considered that the temperature of the electronic device is too high. In this case, the electronics can switch the receiver coil to a low power receiver coil.

For example, if the temperature of the electronic device is 60 degrees, the preset temperature threshold is 35 degrees, and the preset temperature difference is 10 degrees, then since the temperature difference between the temperature of the electronic device and the preset temperature threshold is 25 degrees, the preset temperature difference exceeds the preset temperature difference. If the value is 10 degrees, then the electronic device can switch to the low-power receiving coil regardless of whether the electronic device is using a high-power receiving coil or a medium-power receiving coil.

In 206, if the temperature difference is less than the preset temperature difference value and the high-power receiving coil is currently used, the electronic device switches to the medium-power receiving coil, or if the temperature difference is less than the preset temperature-difference value and the medium-power receiving coil is currently used , the electronic device switches to the low power receiving coil.

For example, if the electronic device detects that the temperature difference between its temperature and the preset temperature threshold value is smaller than the preset temperature difference value, it can be considered that the temperature of the electronic device is relatively high. In this case, if the electronic device currently uses a high-power receiving coil, the electronic device may first switch the receiving coil from the high-power receiving coil to the medium-power receiving coil. If the electronic device currently uses a medium-power receiving coil, the electronic device may first switch the receiving coil from a medium-power receiving coil to a low-power receiving coil.

For example, if the temperature of the electronic device is 42 degrees, the preset temperature threshold is 35 degrees, and the preset temperature difference is 10 degrees, then since the temperature difference between the temperature of the electronic device and the preset temperature threshold is 7 degrees, it does not exceed the preset temperature difference The value is 10 degrees, if the electronic device is currently using a high-power receiving coil, the electronic device can switch to a medium-power receiving coil first.

In another example, the temperature of the electronic device is 42 degrees, the preset temperature threshold is 35 degrees, and the preset temperature difference is 10 degrees, then because the temperature difference between the temperature of the electronic device and the preset temperature threshold is 7 degrees, the temperature does not exceed the preset temperature. The temperature difference is 10 degrees. If the electronic device is currently using a medium power receiving coil, the electronic device can switch to a low power receiving coil.

It can be understood that, in this embodiment, when the temperature of the electronic device reaches the preset temperature threshold, the temperature difference between the temperature and the preset temperature threshold is smaller than the preset temperature difference, and the currently used receiving coil is not a low-power receiving coil. In the case of , the electronic device can first reduce the power level of the receiving coil to the next power level, such as switching from a high-power receiving coil to a medium-power receiving coil, or switching from a medium-power receiving coil to a low-power receiving coil.

In 207, if the currently used receiving coil is a low-power receiving coil, the electronic device sends power control information to the wireless charging device, where the power control information is used to instruct the wireless charging device to reduce transmission power.

For example, the electronic device detects that its temperature is greater than or equal to a preset temperature threshold, and the receiving coil currently used by the electronic device is a low-power receiving coil. In this case, the electronic device sends power control information to the wireless charging device (eg, a wireless charging base, etc.), wherein the power control information is used to instruct the wireless charging device to reduce the transmit power.

It can be understood that after the wireless charging device reduces the transmit power, the power received by the receiving coil of the electronic device is also reduced, thereby reducing the temperature of the electronic device.

In an embodiment, in the process of wireless charging, before acquiring the temperature of the electronic device, the following steps may be further included:

Get the current battery level of the electronic device.

Then, the step of acquiring the temperature of the electronic device may include: if the current power value reaches a preset power threshold, the electronic device acquires its temperature.

For example, when performing wireless charging, the electronic device may first obtain its current power value. Afterwards, the electronic device can detect whether the current battery level reaches a preset battery level threshold, for example, the preset battery level threshold is 80%.

If the electronic device detects that the current battery level value does not reach the preset battery level threshold, the electronic device may perform other operations.

If the electronic device detects that the current power value reaches the preset power threshold, the electronic device can obtain its own temperature, and when the temperature is greater than or equal to the preset temperature threshold and the currently used receiving coil is not a low-power receiving coil, the The receiving coil is switched. For example, if a high-power receiving coil is currently used, the electronic device switches to a non-high-power receiving coil, and if a medium-power receiving coil is currently used, the electronic device switches to a low-power receiving coil.

For example, the preset power threshold is 80% power of the electronic device. Then, when the power of the electronic device has reached 80%, it can be considered that the electronic device is in the late stage of wireless charging. When the power is relatively sufficient, the user may need to use the electronic device at any time. In this case, the electronic equipment can switch the power level of the receiving coil when its temperature is high, and switch from the receiving coil of the higher power level to the receiving coil of the lower power level, thereby reducing the power level of the electronic equipment. temperature. In this way, when the user picks up the electronic device, the temperature of the electronic device has dropped to a lower state, thereby improving user experience and effectively avoiding the problem of poor user experience caused by overheating of the electronic device caused by charging.

In one embodiment, the step of switching the receiving coil by the electronic device may include:

The electronic device sends a switching instruction to the wireless charging device, and the wireless charging device includes a low-power transmitting coil, a medium-power transmitting coil and a high-power transmitting coil, wherein, if the electronic device currently uses a high-power receiving coil, the switching instruction is used to indicate The wireless charging device switches to a non-high-power transmitting coil; if the electronic device currently uses a medium-power receiving coil, the switching instruction is used to instruct the wireless charging device to switch to a low-power transmitting coil;

The electronic device obtains feedback information of the switching instruction from the wireless charging device, and the feedback information indicates that the wireless charging device has been switched to the corresponding transmitting coil;

The electronic device switches the receiving coil according to the feedback information.

For example, electronic devices currently use high-power receiving coils and need to switch to low-power receiving coils. Then, the electronic device can send a switching instruction to the wireless charging device (eg, a wireless charging base), where the switching instruction is used to instruct the wireless charging device to switch to the low-power transmitting coil. After receiving the switching instruction, the wireless charging device can switch to the low-power transmitting coil according to the switching instruction, and send feedback information to the electronic device, the feedback information indicating that the wireless charging device has been switched to the low-power transmitting coil. After receiving this feedback, the electronic device can switch to a low power receiving coil.

For another example, the electronic device currently uses a high-power receiving coil and needs to switch to a medium-power receiving coil. Then, the electronic device can send a switching instruction to the wireless charging device (eg, a wireless charging base), where the switching instruction is used to instruct the wireless charging device to switch to the medium-power transmitting coil. After receiving the switching instruction, the wireless charging device can switch to the medium-power transmitting coil according to the switching instruction, and send feedback information to the electronic device, the feedback information indicating that the wireless charging device has been switched to the medium-power transmitting coil. After receiving the feedback information, the electronic device can switch to the medium power receiving coil.

For another example, the electronic device currently uses a medium-power receiving coil, and needs to switch to a low-power receiving coil. Then, the electronic device can send a switching instruction to the wireless charging device (eg, a wireless charging base), where the switching instruction is used to instruct the wireless charging device to switch to the low-power transmitting coil. After receiving the switching instruction, the wireless charging device can switch to the low-power transmitting coil according to the switching instruction, and send feedback information to the electronic device, the feedback information indicating that the wireless charging device has been switched to the low-power transmitting coil. After receiving this feedback, the electronic device can switch to a low power receiving coil.

Please refer to FIG. 3 . FIG. 3 is a third schematic flowchart of the coil switching method provided by the embodiment of the present application. The coil switching method can be applied to a wireless charging device such as a wireless charging base. The wireless charging device may include a transmit coil assembly. The transmit coil assembly may include a low power transmit coil, a medium power transmit coil, and a high power transmit coil.

The flow of the coil switching method may include:

In 301, a switching instruction is obtained from the electronic device, wherein if the electronic device currently uses a high-power receiving coil, the switching instruction is used to instruct the wireless charging device to switch to a non-high-power transmitting coil; If a medium-power receiving coil is used, the switching instruction is used to instruct the wireless charging device to switch to a low-power transmitting coil.

In 302, according to the switching instruction, switch to the corresponding transmitting coil.

For example, the wireless charging device is a wireless charging base. When the wireless charging base receives the switching instruction from the electronic device, the wireless charging base can switch to the corresponding transmitting coil according to the switching instruction. Wherein, if the electronic device currently uses a high-power receiving coil, the switching instruction is used to instruct the wireless charging base to switch to a non-high-power transmitting coil. If the electronic device currently uses a medium-power receiving coil, the switching instruction is used to instruct the wireless charging base to switch to a low-power transmitting coil.

In 303, feedback information is sent to the electronic device, the feedback information indicating that the wireless charging device has been switched to the corresponding transmitting coil.

For example, after switching to the corresponding transmitting coil, the wireless charging base can send feedback information to the electronic device, and the feedback information indicates that the wireless charging base has been switched to the corresponding transmitting coil.

It should be noted that, in this embodiment, the wireless charging device includes transmitting coils of different power levels, namely: high-power transmitting coils, medium-power transmitting coils, and low-power transmitting coils. The electronic device includes receiving coils of different power levels, namely: high-power receiving coils, medium-power receiving coils, and low-power receiving coils. During wireless charging, the transmitting coil and the receiving coil are coils of the same power level. For example, if the wireless charging device uses a high-power transmitting coil, the corresponding electronic device uses a high-power receiving coil. If the wireless charging device uses a medium-power transmitting coil, the corresponding electronic device uses a medium-power receiving coil. If the wireless charging device uses a low-power transmitting coil, the corresponding electronic device uses a low-power receiving coil.

In an implementation manner, this embodiment may further include the following steps:

When the power control information is acquired from the electronic device, the wireless charging device reduces the transmit power according to the power control information.

For example, electronic devices currently use low-power receiving coils, and correspondingly, wireless charging bases use low-power transmitting coils. The electronic device sends power control information to the wireless charging base, where the power control information is used to instruct the wireless charging base to reduce the transmit power. Then, after receiving the power control information, the wireless charging base can reduce the transmit power according to the power control information.

Please refer to FIGS. 4 to 7 . FIGS. 4 to 7 are schematic diagrams of scenarios of the coil switching method provided by the embodiments of the present application.

For example, as shown in FIG. 4 , the user places the electronic device 40 on the wireless charging base 50 for wireless charging. The receiving coil of the electronic device 40 is a receiving coil assembly, and the receiving coil assembly includes a low-power receiving coil 41 , a medium-power receiving coil 42 and a high-power receiving coil 43 . In addition, the electronic device also includes a control circuit 44 . The control circuit 44 is electrically connected to the receiving coil assembly. The control circuit 44 is used to selectively electrically connect to the low-power receiving coil 41 or the medium-power receiving coil 42 or the high-power receiving coil 43 according to the instruction of the electronic device 40 , as shown in FIG. 5 . The transmitting coil of the wireless charging base 50 is a transmitting coil assembly, and the transmitting coil assembly includes a low-power transmitting coil 51 , a medium-power transmitting coil 52 and a high-power transmitting coil 53 . In addition, the electronic device also includes a control circuit 54 . The control circuit 54 is electrically connected to the transmit coil assembly. The control circuit 54 is used for selectively electrically connecting to the low-power transmitting coil 51 , the medium-power transmitting coil 52 or the high-power transmitting coil 53 according to the instruction of the wireless charging base 50 , as shown in FIG. 6 .

For example, when the electronic device is placed on the wireless charging base for wireless charging, the video application A in the electronic device pushes a popular video to the user. After receiving the video of the big push, the user clicks the video to play, as shown in Figure 7.

At this point, the electronic device can detect that a foreground application is running. In this case, the electronic device may acquire its own temperature at preset time intervals, and detect whether the temperature is greater than or equal to the preset temperature threshold.

For example, the preset temperature threshold is 40 degrees. While the electronic device was still playing the video, the electronic device detected that its own temperature reached 45 degrees, exceeding a preset temperature threshold. In this case, the electronic device can determine whether the currently used receiving coil is a low-power receiving coil.

For example, the electronic device determines that the currently used receiving coil is a high-power receiving coil. In this case, the electronic device can calculate the temperature difference between its current temperature and a preset temperature threshold, and detect whether the temperature difference is greater than or equal to the preset temperature difference value. For example, the temperature difference between the current temperature of the electronic device and the preset temperature threshold is 5 degrees less than the preset temperature difference value of 10 degrees. In this case, the electronic device may determine that the receiving coil needs to be switched from a high power receiving coil to a medium power receiving coil.

At this time, the electronic device can send a switching instruction to the wireless charging base, and the switching instruction is used to instruct the wireless charging base to switch to the medium-power transmitting coil.

After receiving the above switching instruction, the wireless charging base can switch from the high-power transmitting coil to the medium-power transmitting coil according to the switching instruction, and send feedback information to the electronic device, which indicates that the wireless charging base has been switched to the medium-power transmitting coil. .

After receiving the above feedback information, the electronic device can switch from the high-power receiving coil to the medium-power receiving coil.

It can be understood that the temperature of the wireless charging base can be reduced after switching from the high-power transmitting coil to the medium-power transmitting coil, and the temperature of the electronic device can also be reduced after switching from the high-power receiving coil to the medium-power receiving coil. It enables electronic devices and wireless charging bases to avoid the problem of excessive temperature during wireless charging.

Please refer to FIG. 8 , which is a schematic structural diagram of a coil switching device provided by an embodiment of the present application. The coil switching device 600 can be applied to electronic equipment.
