The second optical receiver converts the received optical pulse signal into an electrical signal, and then sends it to the decoder for demodulation after amplification, filtering and other processing, and then restores it to the charging configuration parameter of the binary digital signal and outputs it.

In some embodiments, the electronic device further includes a first optical receiver, and the wireless charging device further includes a second optical transmitter; before transmitting the charging configuration parameters of the electronic device to the wireless charging device in a wireless communication manner, the method further includes: An optical transmitter sends a detection optical pulse signal to the second optical receiver; the second optical transmitter sends a feedback optical pulse signal to the first optical receiver.

It should be noted that before transmitting the charging configuration parameters to the wireless charging device, the electronic device needs to perform light induction detection through the first data transmission device and the second data transmission device to ensure that the first data transmission device and the second data transmission device Wireless data transmission can be carried out between devices, thereby improving the accuracy of wireless data transmission.

Exemplarily, the first light emitter in the electronic device sends a detection light pulse signal to the second light receiver in the wireless charging device; if the second light receiver receives the detection light pulse signal, then the second light receiver in the wireless charging device The second light emitter transmits a feedback light pulse signal to the first light receiver in the electronic device; the first light receiver in the electronic device receives the feedback light pulse signal sent by the second light emitter in the wireless charging device.

In some embodiments, a wireless charging device includes a control chip and a light receiver. The optical receiver includes a light-sensing communication interface D1+/D1-. The light-sensing communication interface D1+/D1- is used to receive the charging configuration parameters sent by the electronic device. The light-sensing communication interface D1+/D1- also corresponds to the signal pin in the connection control chip. Pins D+ and D- output the charging configuration parameters to the control chip through the signal pins D+ and D-, thereby accurately receiving the charging configuration parameters sent by the electronic device.

Step S302: The wireless charging device outputs the target voltage according to the charging configuration parameters.

The charging configuration parameters are transmitted from the electronic device to the wireless charging device through wireless communication. The wireless charging device outputs a target voltage according to the charging configuration parameters to wirelessly charge the electronic device in a wireless charging manner.

In some embodiments, the charging configuration parameters include battery charging voltage; outputting the target voltage according to the charging configuration parameters includes: determining a target voltage to be provided according to the battery charging voltage; and providing the target voltage to the electronic device. For example, if the battery charging voltage is 9V, then the battery charging voltage of 9V is used as the target voltage to be provided, that is, the target voltage to be provided is also 9V. In some embodiments, the charging configuration parameters include a battery charging voltage, based on the battery charging voltage and the power consumption voltage to determine the target voltage to be provided. For example, if the battery charging voltage is 9V and the loss voltage during wireless power transmission is 1.5V, then the sum of the battery charging voltage of 9V and the loss voltage of 1.5V is calculated as the target voltage to be provided, that is, the target voltage is 10.5V.

In some embodiments, the charging configuration parameters include battery charging power, and the wireless charging device determines the target voltage to be provided based on the battery charging power. For example, obtain the output current of the wireless charging device, and calculate the ratio of battery charging power to output current to determine the target voltage to be provided. In some embodiments, the charging configuration parameters include battery charging voltage and battery charging current, and the target voltage to be provided is determined according to the battery charging voltage and battery charging current, so that the target voltage output by the wireless charging device is consistent with the battery charging voltage, battery charging Current matching.

In some embodiments, the charging configuration parameters also include the current voltage of the battery; determining the target voltage to be provided based on the battery charging voltage includes: determining whether the current voltage of the battery is less than the preset battery full voltage; if the current battery voltage is less than the battery full voltage voltage, the target voltage to be provided by the wireless charging device is determined based on the battery charging voltage.

The battery full-charge voltage can be preset according to the actual situation of the battery in the electronic device. By judging whether the current battery voltage is less than the preset battery full-charge voltage, it is determined whether the battery in the electronic device meets the charging conditions. If the current voltage of the battery is less than the full battery voltage, it indicates that the battery in the electronic device is not fully charged. At this time, the battery in the electronic device meets the charging conditions. Therefore, the target voltage to be provided by the wireless charging device can be determined based on the battery charging voltage, so as to pass This target voltage charges the battery in the electronic device.

For example, the charging configuration parameters include the battery charging voltage and the current battery voltage; determine whether the current battery voltage is less than the preset battery full voltage; if the current battery voltage is less than the battery full voltage, determine the wireless charging device based on the battery charging voltage. target voltage provided. For example, the fully charged battery voltage is 4.2V and the battery charging voltage is 9V. If the current battery voltage is greater than or equal to 4.2V, it means that the electronic device is fully charged and does not need to be charged. If U is less than 4.2V, it indicates that the battery in the electronic device is not fully charged and needs to be charged. At this time, the wireless charging device can use the obtained battery charging voltage 9V as the target voltage to be provided.

In some embodiments, the wireless charging device includes a plurality of switch tubes, a voltage dividing circuit connected to the plurality of switching tubes, and a wireless charging device connected to the voltage dividing circuit; providing a target voltage to the electronic device includes: according to the target voltage, Determine a target switch tube to be turned on from a plurality of switch tubes; turn on the target switch tube to control the voltage dividing circuit to output a target voltage to the wireless charging device, and enable the wireless charging device to provide the target voltage to the electronic device.

It should be noted that the wireless charging device can adjust the resistance of the voltage dividing resistor of the voltage dividing circuit by controlling the on and off switching tube, thereby accurately adjusting the output voltage of the voltage dividing circuit. If the switching tubes are conducting more and the voltage dividing resistors are connected in parallel and become smaller, the output target voltage will become larger again. If the switch tube conducts less and the voltage dividing resistor becomes larger, the output target voltage will become smaller.

For example, as shown in Figure 4, the wireless charging device includes switch tube V1, switch tube V2 and switch tube V3. The voltage dividing circuit includes resistors R1 to resistors R5. Pin 1 of the control chip is grounded, and the pin 1 of the control chip is grounded. 2 to 4 are used respectively The switching tubes V1 to V3 are connected, and each switching tube V1 to V3 is respectively connected to the resistor R1 to the resistor R3 in the voltage dividing circuit. Pin 5 of the control chip is the data D+ input, and pin 6 is the data D- input. Data D+ and data D- are, for example, the charging voltage in the charging configuration parameters sent by the electronic device. The control chip can use the voltages on D+ and D- to determine which switching tube among the switching tubes V1/V2/V3 is turned on to determine the output. The size of the target voltage VOUT.

For example, pin 2 of the control chip controls the 9V/12V/20V voltage output, pin 3 controls the 12V/20V voltage output, and pin 4 controls the 20V voltage output. The output voltage detection device is used to detect the size of the output voltage. If the switch V1 is turned on, then the resistor R5 and the resistor R1 will be connected in parallel, and the resistance value will become smaller than before, that is, the voltage dividing resistor value of the voltage dividing circuit will become smaller, and then the output voltage VOUT will become larger, for example Arrive at 9V. Similarly, if the switch tubes V1/V2 are both turned on, then the resistors R5, R1 and R2 are connected in parallel, the voltage dividing resistor will become smaller, and the output voltage VOUT will become larger again, for example, reaching 12V. If the switch tubes V1/V2/V3 are all turned on, then the resistor R5 is connected in parallel with R1, R2, and R3, the voltage dividing resistor will become smaller, and the output voltage VOUT will become larger again, for example, reaching 20V.

Step S303: The electronic device performs wireless charging according to the target voltage.

The wireless charging device provides a target voltage to the electronic device in a wireless power supply manner. For example, the electronic device obtains an induced voltage by coupling the target voltage, and charges the battery in the electronic device through the induced voltage.

Exemplarily, the wireless charging device includes a wireless charging device (a second wireless charging device). The wireless charging device controls the wireless charging device to output a target voltage according to the charging configuration parameters. The wireless charging device charges the electronic device in a wireless charging manner. for wireless charging. Therefore, electronic devices can achieve wireless charging and wireless data transmission without setting up external charging interfaces or data interfaces, which can improve the waterproof performance of electronic devices and improve the security of transmitted data.

In some embodiments, the electronic device performs wireless charging by generating current through changes in magnetic flux of the electromagnetic coil. The second wireless charging device in the wireless charging device is used to provide a uniform magnetic field, and the first wireless charging device in the electronic device is perpendicular or not perpendicular to the uniform magnetic field. Assume that there is a plane perpendicular to the direction of the magnetic field in a uniform magnetic field, the magnetic induction intensity of the magnetic field is B, and the area of the plane is S. When the plane is perpendicular to the magnetic field direction, the product of the magnetic induction intensity B and the area S perpendicular to the magnetic field direction is the magnetic flux Φ, Φ=BS. When the plane is not perpendicular to the direction of the magnetic field, the magnetic flux Φ = BScos θ, θ is the angle between the perpendicular line of the plane and the direction of the magnetic field.

Since the current is caused by the induced electromotive force of the power supply, electronic equipment must also produce changes in the induced electromotive force E. The induced electromotive force E can be generated by changes in the size of the magnetic force. There are mainly two methods to generate the induced electromotive force E: One method It is to make the conductor in the closed circuit move in the magnetic field to cut the magnetic field lines. As shown in Figure 5, assuming that the length of a conductor is L, when it moves at a speed v to cut the magnetic induction line in a uniform magnetic field with a magnetic induction intensity B, when B/L/v are perpendicular to each other, the induced electromotive force generated in the conductor is The size is: E=BLv. When a conductor moves at a uniform speed cutting magnetic field lines in a uniform magnetic field, regardless of whether the circuit is closed or not, the magnitude of the induced electromotive force is only related to the magnetic induction intensity B, conductor length L, cutting speed v and the sine value of the angle θ between v and the direction B. Proportional to E=BLvsinθ. Another way is Let the magnetic field move within the conductor. The magnitude of the change in magnetic force is related to the strength, speed, and size of the change in magnetic force passing through the closed circuit. When the magnetic force passing through an unclosed coil changes, although there is no induced current in the coil, the induced electromotive force still exists. When the conductor rod does not cut the magnetic field lines, but there is a change in magnetic force in the closed loop, induced current can also be generated.

In some embodiments, the electronic device is wirelessly charged through the first wireless charging device and the second wireless charging device. The first wireless charging device includes a first coil, and the second wireless charging device includes a second coil. The first coil and the second coil can be electromagnetic coils, and the first coil and the second coil can also be magnetically charged. For example, the first coil and the second coil rely on magnetic positive and negative poles to attract each other, and are within a certain distance through the positive and negative magnetism. Automatically adsorbs to achieve the function of charging when it is turned on. A magnet is fixed on the first coil or the second coil, and a magnetic substance is also fixed on the other end.
