[0080] Reference Figure 2 In one embodiment of the control method of the wireless charging device of the present invention, the control method of the wireless charging device comprises the following steps:

[0081] Step S1, obtaining system parameters during wireless charging;

[0082] Step S2, when the system parameters meet the condition for stopping charging, turning off the wireless charging receiving component of the wireless charging receiving component;

[0083] Step S3, controlling the first light-emitting component to output a stop-charging light coding signal, wherein the charging base turns off the enabling of the wireless charging transmitting component when receiving the stop-charging light coding signal through the second light sensing component.

[0084] With the development of wireless terminal technology and the convenience of wireless charging, more and more electronic devices are equipped with wireless charging functions. Especially in some wearable devices, such as electronic bracelets, smart glasses and smart headphones, the support of wireless charging technology makes the charging process of wearable devices easier.

[0085] In the related art, when the terminal device is wirelessly charging, when the temperature reaches the threshold, the software will shut down the wireless charging chip of the terminal device, thereby stopping the wireless charging process. At this time, in order to determine whether the terminal device is in place, the wireless charging base will frequently initiate a Ping (Packet Internet Groper, connection test) signal. The electrical energy sent by the wireless charging base to send the ping signal will eventually be converted into heat, which will cause the terminal device to cool down at a slower rate.

[0086] After the terminal device enters the stop charging state due to the over-high charging temperature, it will not enter the recharging stage until its own temperature drops to a safe temperature. Therefore, the terminal device cooling speed will be reduced due to the related technical solution to achieve terminal device detection, which will lead to a longer charging time for the terminal device.

[0087] In order to solve the above-mentioned defects of the related art, an embodiment of the present invention provides a control method of a wireless charging device.

[0088] In this embodiment, the control method of the wireless charging device is executed by a terminal device, and the terminal device includes a wireless charging receiving component and a first light-emitting component. The wireless charging receiving component at least includes a power receiving coil. The first light-emitting component at least includes a light-emitting element.

[0089] When the terminal device is wirelessly charged, it can monitor its own system parameters, wherein the system parameters may include the temperature of the terminal device and the current power of the terminal device.

[0090] Specifically, during the charging process of the terminal device, since the battery is likely to generate heat during the charging process, a temperature sensor can be set at the location of the battery of the terminal device to obtain the temperature of the battery as the temperature of the terminal device. In addition, the terminal device is also provided with a power detection function, so that the current power of the battery can be detected during the charging process.

[0091] After the system parameters are acquired, it may be determined in real time and / or periodically whether the system parameters meet the condition for stopping charging.

[0092] Specifically, in some optional implementation schemes, when the battery charging temperature is too high, the temperature of the entire terminal device will rise accordingly. The processor, memory, etc. of the terminal device will accelerate aging in a high temperature environment. This causes the terminal device to become stuck. For the battery itself, excessively high temperature will cause the electrolyte to gasify, resulting in a shortened battery life. Therefore, in order to extend the service life of the terminal device and slow down the aging speed of the terminal device, the stop charging adjustment can be set to a temperature of the terminal device greater than the first temperature. Among them, the first temperature can be selectively set according to the heat resistance of the components of the terminal device. That is, for a terminal device with a strong heat resistance of the component, the specific value corresponding to the first temperature can be set to be greater than the specific value corresponding to the first temperature of the terminal device with a weak heat resistance of the component. For example, in a terminal device with a strong heat resistance of the component, the first temperature is set to 60°C, and in a terminal device with a weak heat resistance of the component, the first temperature is set to 4560°C.

[0093] In some other optional implementation schemes, when the terminal device is fully charged, in order to prevent the wireless charger from continuing to charge the terminal device, thereby causing the metal in the terminal device to heat up due to eddy currents. The stop charging adjustment can be set to the current power of the terminal device being greater than or equal to the first power. Among them, in some application scenarios, the first power can be set to 100%. In other application scenarios, when the battery is not suitable for charging to 100% due to various protection reasons or other reasons, it can be set to other values ​​lower than 100%.

[0094] When the system parameters meet the conditions for stopping charging, it is determined that the terminal device needs to stop charging at this time. Therefore, the terminal device can turn off the enabling of its own wireless charging receiving component when the system parameters meet the conditions for stopping charging, thereby suspending charging.

[0095] Furthermore, in order to prevent the charging base from continuing to send a ping signal to the terminal device at this time, or continuing to supply energy to the terminal device through the transmitting coil, resulting in a degradation in the performance of the terminal device, the terminal device can control the first light-emitting component to output a stop charging light coding signal, that is, send a stop charging light coding signal to the charging base.

[0096] Specifically, the first light-emitting component may include a light-emitting device such as an LED (Light Emitting Diode) lamp, wherein the stop-charging light coding signal is configured to light up the light-emitting device according to a preset lighting method. For example, flashing at a preset frequency, or emitting light of a preset wavelength. It is understandable that a second light-sensing component is provided on the charging base. Thus, the stop-charging light coding signal sent by the terminal device can be received. When the charging base receives the stop-charging light coding signal, it turns off the enabling of the wireless charging transmitting component and does not send a ping signal to the terminal device.

[0097] In an optional implementation, after turning off the enabling of its own wireless charging receiving component, the terminal device can also determine whether the system parameters meet the recharging conditions, wherein the recharging conditions include the temperature of the terminal device being less than or equal to a second temperature, and the current power of the terminal device being less than or equal to a second power, wherein the first temperature is greater than the second temperature, and the first power is greater than the second power.

[0098] It is understandable that when the terminal device enters the stop charging state due to the over-high charging temperature, it can automatically enter the recharging state when the temperature drops to or is lower than the second temperature, that is, automatically start the charging function. Or it can automatically enter the recharging state when the power reaches the first threshold value.

[0099] Furthermore, when the system parameters meet the recharging conditions, the wireless charging receiving component itself can be enabled first, and then the first light-emitting component can be controlled to send a recharging light coding signal to the charging base, so that when the charging base receives the recharging light coding signal, it can enable its own wireless charging transmitting component.

[0100] In another optional embodiment, the terminal device is further provided with a first light sensing component, wherein the first light sensing component can receive the light signal sent by the charging base.

[0101] Specifically, the first light sensing component includes a photodiode, which can convert the optical signal into an electrical signal and send it to the processor. Wherein, when the terminal device is a smart watch or smart bracelet with a heart rate detection function, the heart rate photodiode at the bottom can be reused as a photodiode of the light sensing component. Then, after the system parameters meet the conditions for stopping charging and the enabling of the wireless charging receiving component is turned off, it is determined whether the in-place optical coding signal sent by the charging base is received. If so, it is determined that the charging base is in place, and the step of controlling the first light-emitting component to output the stop charging optical coding signal is executed. Otherwise, it is determined that the charging base is not in place, and the terminal device ends the current charging process.

[0102] In the technical solution disclosed in this embodiment, when wireless charging is performed, the system parameters are first obtained, and then when the system parameters meet the conditions for stopping charging, the enabling of the wireless charging receiving component is turned off, and the first light-emitting component is controlled to output a stop-charging light coding signal, wherein the charging base turns off the enabling wireless charging receiving component of the wireless charging transmitting component when receiving the stop-charging light coding signal through the second light sensing component. Since it is possible to communicate with the charging base through an optical signal when the conditions for stopping charging are met, the charging base is controlled to stop supplying energy to the terminal device, thereby avoiding the occurrence of the device temperature rise phenomenon caused by the charging base function.

[0103] Reference Figure 3 In one embodiment of a control method for a wireless charging device of the present invention, the control method for a wireless charging device comprises the following steps:

[0104] Step S10: when a charging stop light coding signal output by the terminal device is received through the second light sensing component, the wireless charging transmitting component is turned off.

[0105] In this embodiment, the control method of the wireless charging device is executed by a charging base, wherein the charging base includes a second light sensing component and a wireless charging transmitting component, wherein the wireless charging transmitting component includes at least a transmitting coil.

[0106] When the charging base receives the stop-charging optical coding signal sent by the terminal device, the wireless charging transmitting component is turned off. Wherein, when the charging base receives the stop-charging optical coding signal sent by the terminal device, the charging base determines that the terminal device has entered the stop-charging stage. In order to save energy and avoid heating of the terminal device, when the terminal device is in the stop-charging stage, the power supply to the terminal device is stopped. Wherein, it includes not sending a start ping signal to the terminal device. That is, the presence of the terminal device is judged by the stop-charging optical coding signal.

[0107] In an optional implementation, after turning off the wireless charging transmitter component, the charging base can periodically detect whether the stop charging light coding signal is received. When the charging base receives the stop charging light coding signal sent by the terminal device, the step of turning off the wireless charging transmitter component is continued. Otherwise, the wireless charging transmitter component is enabled.

[0108] In another optional implementation, after turning off the enabling of the wireless charging transmitting component, the charging base can enable its own wireless charging transmitting component upon receiving the recharging optical coding signal sent by the terminal device to cooperate with the terminal device to enter the recharging stage.

[0109] Optionally, when the terminal device enters the charging stop stage, in order to enable the terminal device to obtain the presence status of the charging base, the charging base can control the second light-emitting component to send a presence light coding signal after turning off the enablement of the wireless charging transmitting component.

[0110] Optionally, when the charging base does not receive the stop charging optical coding signal sent by the terminal device, if it has not established a charging state with any terminal device, it is determined that it is in an idle state. Then, it can enter the standby state and output a prompt message that it is in the standby state. In the standby state, the charging base only turns on the device detection function, and after detecting a new terminal device, it establishes a charging relationship with the terminal device.

[0111] In the technical solution disclosed in this embodiment, when the charging base receives the stop charging optical coding signal sent by the terminal device, the wireless charging transmitting component is turned off. This can avoid the terminal device from functioning when it meets the conditions for stopping charging. This can increase the cooling speed of the terminal device during the stop charging stage and shorten the time for over-temperature stop charging. This achieves the effect of shortening the charging time of the terminal device.

[0112] In addition, an embodiment of the present invention further proposes a wireless charging device, which includes a memory, a processor, and a control program of the wireless charging device stored in the memory and executable on the processor. When the control program of the wireless charging device is executed by the processor, the steps of the control method of the wireless charging device described in the above embodiments are implemented.

[0113] In addition, an embodiment of the present invention further proposes a computer-readable storage medium, on which a control program of a wireless charging device is stored. When the control program of the wireless charging device is executed by a processor, the steps of the control method of the wireless charging device described in the above embodiments are implemented.
