Referring to fig. 1, fig. 1 is a first flowchart illustrating a coil switching method according to an embodiment of the present disclosure. The coil switching method may be applied to an electronic device that may include a receive coil assembly that may include a low power receive coil, a medium power receive coil, and a high power receive coil. The flow of the coil switching method may include:
in 101, the temperature of the electronic device is acquired while wireless charging is performed.
With the continuous development of technologies, more and more electronic devices are applied to wireless charging. Wireless charging refers to the transfer of electrical energy through a non-conductive substance. In practical applications, wireless charging generally refers to transferring electric energy across a certain spatial distance. The wireless charging technology is realized mainly through the following four ways: electromagnetic induction type, magnetic field resonance type, radio wave type, and electric field coupling type. However, in the related art, the temperature of the electronic device is high during the wireless charging.
In 101 of the embodiment of the present application, for example, during the process of performing wireless charging, the electronic device may acquire its own temperature.
After obtaining the temperature of the electronic device, the electronic device may detect whether the temperature is greater than or equal to a preset temperature threshold.
If the detected temperature is less than the preset temperature threshold, the temperature of the electronic device may be considered to be low. At this time, the electronic device may perform other operations.
If the temperature is detected to be greater than or equal to the predetermined temperature threshold, then 102 is entered.
At 102, if the temperature of the electronic device is greater than or equal to the 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, the temperature of the electronic device may be considered to be higher. In this case, the electronic device may determine whether its currently used receive coil is a low power receive coil.
If the electronic device determines that the currently used receive coil is a low power receive coil, the electronic device may perform other operations. For example, the electronic device may continue to use the low power receive coil for wireless charging.
If the electronic device determines that its currently used receive coil is not a low power receive coil, then proceed 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 receiving coil is a high power receiving coil, the receiving coil is switched to a non-high power receiving coil, and if the currently used receiving coil is a medium power receiving coil, the receiving coil is switched to a low power receiving 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 may switch the receiving coil. If a high-power receiving coil is currently used, the electronic device may be switched from the high-power receiving coil to a non-high-power receiving coil, for example, to a medium-power receiving coil or a low-power receiving coil. If a medium power receiving coil is currently used, the electronic device can be switched from the medium power receiving coil to the low power receiving coil. The electronic device can then use the switched receive coil for wireless charging.
It is understood that, in the present 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. When wireless charging is carried out, if the temperature of the electronic device is greater than or equal to a preset temperature threshold value and a receiving coil used by the electronic device is not a low-power receiving coil, the electronic device can be switched from a high-power receiving coil to a non-high-power receiving coil or from a medium-power receiving coil to a low-power receiving coil, so that the charging power of the terminal is reduced. After the charging power of the electronic equipment is reduced, the temperature of the electronic equipment can be reduced, so that the problem that the temperature of the electronic equipment is too high in the wireless charging process is effectively solved.
Referring to fig. 2, fig. 2 is a second flowchart of a coil switching method according to an embodiment of the present disclosure. The coil switching method may be applied to an electronic device that may include a receive coil assembly that may include a low power receive coil, a medium power receive coil, and a high power receive coil. The flow of the coil switching method may include:
in 201, the electronic device detects whether a foreground application is running while performing wireless charging.
For example, in the process of wireless charging, the electronic device may detect whether a foreground application is 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 currently plays a video through a certain video application, the video application is a foreground application.
If no foreground application is currently detected to be running, the electronic device may perform other operations.
If it is detected that there is currently a foreground application running, then 202 is entered.
At 202, if there is a foreground application running, the electronic device obtains its temperature.
For example, the electronic device detects that the user is currently playing a video using the video application a, and then the electronic device may determine that a foreground application is currently running, and at this time, the electronic device may obtain the temperature of the electronic device itself.
For example, in one embodiment, the electronic device may acquire its own temperature at preset time intervals. Alternatively, the electronic device may acquire its own temperature in real time.
After obtaining the temperature of the electronic device, the electronic device may detect whether the temperature is greater than or equal to a preset temperature threshold.
If the temperature is detected to be less than the preset temperature threshold, the temperature of the electronic device may be deemed still low and the electronic device may perform other operations.
If the temperature is detected to be greater than or equal to the preset temperature threshold, 203 is entered.
At 203, if the temperature is greater than or equal to the 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 the temperature thereof is greater than or equal to the preset temperature threshold, the electronic device may determine whether the currently used receiving coil is a low-power receiving coil.
If it is determined that the receiving coil it is currently using is not a low power receiving coil, then proceed to 204.
If the currently used receive coil is determined to be a low power receive coil, then proceed to 207.
At 204, if the currently used receiver coil is not a low power receiver coil, the electronic device obtains a temperature difference between the temperature of the currently used receiver coil 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 may obtain a temperature difference between the temperature of the electronic device and a preset temperature threshold. Thereafter, the electronic device may detect whether the temperature difference is greater than or equal to a preset temperature difference value.
If it is detected that the temperature difference is greater than or equal to the preset temperature difference value, 205 is entered.
If the temperature difference is detected to be less than the preset temperature difference value, then 206 is entered.
In 205, if the temperature difference is greater than or equal to the predetermined 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 the temperature of the electronic device and the preset temperature threshold is greater than or equal to the preset temperature difference value, the temperature of the electronic device may be considered to be too high. In this case, the electronics can switch the receive coil to a low power receive 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 value is 10 degrees, then since the temperature difference between the temperature of the electronic device and the preset temperature threshold is 25 degrees and exceeds the preset temperature difference value by 10 degrees, the electronic device can be switched to the low-power receiving coil no matter whether the electronic device uses the high-power receiving coil or the medium-power receiving coil.
At 206, the electronic device switches to the medium power receiving coil if the temperature difference is less than the predetermined temperature difference value and the high power receiving coil is currently used, or switches to the low power receiving coil if the temperature difference is less than the predetermined temperature difference value and the medium power receiving coil is currently used.
For example, if the electronic device detects that the temperature difference between the temperature of the electronic device and the preset temperature threshold is smaller than the preset temperature difference value, the temperature of the electronic device may be considered to be higher. 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 the 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 value is 10 degrees, then since the temperature difference between the temperature of the electronic device and the preset temperature threshold is 7 degrees and does not exceed the preset temperature difference value by 10 degrees, if the electronic device currently uses a high-power receiving coil, the electronic device may first switch to a medium-power receiving coil.
For another example, if the temperature of the electronic device is 42 degrees, the preset temperature threshold is 35 degrees, and the preset temperature difference value is 10 degrees, then since the temperature difference between the temperature of the electronic device and the preset temperature threshold is 7 degrees and does not exceed the preset temperature difference value by 10 degrees, if the electronic device currently uses the medium-power receiving coil, the electronic device may switch to the low-power receiving coil.
It can be understood that, in this embodiment, in the case that 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 value, and the currently used receiving coil is not the low-power receiving coil, the electronic device may first reduce the power level of the receiving coil to the next power level, for example, switch from the high-power receiving coil to the medium-power receiving coil, or switch from the medium-power receiving coil to the 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 the 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 (e.g., wireless charging base, etc.), where the power control information is used to instruct the wireless charging device to reduce the transmission power.
It can be understood that, after the wireless charging device reduces the transmission power, the power received by the receiving coil of the electronic device is also reduced, so that the temperature of the electronic device is reduced.
In one embodiment, before acquiring the temperature of the electronic device during the wireless charging, the method may further include:
and acquiring the current electric quantity value of the electronic equipment.
Then, the step of acquiring the temperature of the electronic device may include: and if the current electric quantity value reaches the preset electric quantity threshold value, the electronic equipment acquires the temperature of the electronic equipment.
For example, when performing wireless charging, the electronic device may first obtain its current electric quantity value. Thereafter, the electronic device may detect whether the current charge value reaches a preset charge threshold, for example, the preset charge threshold is 80%.
If the electronic device detects that the current charge value does not reach the preset charge threshold, the electronic device may perform other operations.
If the electronic device detects that the current electric quantity value reaches the preset electric quantity threshold value, the electronic device can acquire the temperature of the electronic device, and when the temperature is larger than or equal to the preset temperature threshold value and the currently used receiving coil is not the low-power receiving coil, 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% of the power of the electronic device. Then, when the electric quantity of the electronic device reaches 80%, the electronic device is considered to be in the later stage of wireless charging, and under the condition that the electric quantity is sufficient, the user is likely to need to use the electronic device at any time. In this case, the electronic device may switch the power level of the receiving coil when the temperature of the electronic device is high, and switch the receiving coil of the higher power level to the receiving coil of the lower power level, thereby reducing the temperature of the electronic device. Therefore, when the user picks up the electronic equipment, the temperature of the electronic equipment is already reduced to a lower state, so that the user experience is improved, and the problem of poor user experience caused by overhigh temperature of the electronic equipment due to charging is effectively avoided.
In one embodiment, the step of switching the receiving coil by the electronic device may include:
the electronic equipment sends a switching instruction to the wireless charging equipment, wherein the wireless charging equipment comprises a low-power transmitting coil, a medium-power transmitting coil and a high-power transmitting coil, and the switching instruction is used for indicating the wireless charging equipment to be switched to a non-high-power transmitting coil if the electronic equipment currently uses a high-power receiving coil; if the electronic equipment currently uses the medium-power receiving coil, the switching instruction is used for indicating the wireless charging equipment to be switched to the low-power transmitting coil;
the electronic equipment acquires feedback information of the switching instruction from the wireless charging equipment, wherein the feedback information indicates that the wireless charging equipment is 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 receive coils and require switching to low power receive coils. Then, the electronic device may send a switch instruction to the wireless charging device (e.g., wireless charging dock) instructing the wireless charging device to switch to the low-power transmitting coil. After receiving the switching instruction, the wireless charging device may switch to the low-power transmitting coil according to the switching instruction and send feedback information to the electronic device, where the feedback information indicates that the wireless charging device has switched to the low-power transmitting coil. Upon receiving the feedback information, the electronic device may switch to a low power receive coil.
As another example, electronic devices currently use high power receive coils and require switching to medium power receive coils. Then, the electronic device may send a switching instruction to the wireless charging device (e.g., wireless charging dock) instructing the wireless charging device to switch to the medium power transmitting coil. After receiving the switching instruction, the wireless charging device may switch to the medium power transmitting coil according to the switching instruction and send feedback information to the electronic device, where the feedback information indicates that the wireless charging device has switched to the medium power transmitting coil. Upon receiving this feedback information, the electronic device may switch to the medium power receiving coil.
As another example, electronic devices currently use medium power receiving coils and need to switch to low power receiving coils. Then, the electronic device may send a switch instruction to the wireless charging device (e.g., wireless charging dock) instructing the wireless charging device to switch to the low-power transmitting coil. After receiving the switching instruction, the wireless charging device may switch to the low-power transmitting coil according to the switching instruction and send feedback information to the electronic device, where the feedback information indicates that the wireless charging device has switched to the low-power transmitting coil. Upon receiving the feedback information, the electronic device may switch to a low power receive coil.
Referring to fig. 3, fig. 3 is a third flowchart illustrating a coil switching method according to an embodiment of the present disclosure. The coil switching method may be applied to a wireless charging apparatus such as a wireless charging cradle. 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 an electronic device, wherein if the electronic device currently uses a high-power receiving coil, the switching instruction is used for instructing the wireless charging device to switch to a non-high-power transmitting coil; if the electronic device currently uses the medium power receiving coil, the switching instruction is used for instructing the wireless charging device to switch to the low power transmitting coil.
In 302, switching to the corresponding transmitting coil is performed according to the switching instruction.
For example, the wireless charging device is a wireless charging base. When the wireless charging base receives a 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 the high-power receiving coil, the switching instruction is used for instructing the wireless charging base to switch to the non-high-power transmitting coil. If the electronic device is currently using 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 indicating that the wireless charging device has switched to the corresponding transmit coil.
For example, after switching to the corresponding transmitting coil, the wireless charging base may send feedback information to the electronic device, where 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 with different power levels, which are respectively: a high power transmit coil, a medium power transmit coil, and a low power transmit coil. The electronic device comprises receiving coils of different power classes, respectively: a high power receiving coil, a medium power receiving coil, and a low power receiving coil. When wireless charging is carried out, the transmitting coil and the receiving coil are coils with 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, 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 transmission power according to the power control information.
For example, electronic devices currently use low power receive coils and, correspondingly, wireless charging cradles use low power transmit 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 transmission power. Then, upon receiving the power control information, the wireless charging base may reduce the transmit power in accordance with the power control information.
Referring to fig. 4 to 7, fig. 4 to 7 are schematic views of a coil switching method according to an embodiment of the present disclosure.
For example, as shown in fig. 4, the user places the electronic device 40 on the wireless charging dock 50 for wireless charging. Among them, the receiving coil of the electronic device 40 is a receiving coil assembly including 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 receive 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 dock 50 is a transmitting coil assembly that 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 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 or 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 a wireless charging dock for wireless charging, a video application a in the electronic device pushes a piece of popular video to the user. After receiving the large pushed video, the user clicks the video to play, as shown in fig. 7.
At this point, the electronic device may 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 a preset temperature threshold.
For example, the preset temperature threshold is 40 degrees. When the electronic equipment still plays the video, the electronic equipment detects that the temperature of the electronic equipment reaches 45 degrees and exceeds a preset temperature threshold value. In this case, the electronic device may determine whether its currently used receive coil is a low power receive coil.
For example, the electronic device determines that the receiving coil currently used by the electronic device is a high-power receiving coil, in which case the electronic device may calculate a temperature difference between the current temperature of the electronic device and a preset temperature threshold, and detect whether the temperature difference is greater than or equal to a preset temperature difference value.

At this time, the electronic device may send a switching instruction to the wireless charging base, where the switching instruction is used to instruct the wireless charging base to switch to the medium power transmitting coil.
After receiving the switching instruction, the wireless charging base may switch the high-power transmitting coil to the medium-power transmitting coil according to the switching instruction, and send feedback information to the electronic device, where the feedback information indicates that the wireless charging base has been switched to the medium-power transmitting coil.
After receiving the feedback information, the electronic device can be switched from the high-power receiving coil to the medium-power receiving coil.
