As shown in FIG. 4, an embodiment of the present disclosure provides a wireless charging method, which is applied to a terminal device. The terminal device includes a first magnet, and the first magnet is an electromagnet. The method includes:

Step 401: In the case that the terminal device and the external charging device are successfully handshaking, control the first magnet to work at the first power.

In this step, when the terminal device is located in the charging area of the charging device, the change of the magnet detected by the terminal device or the charging device can be used, and when the detected magnetic field change satisfies certain conditions, it can be determined that the terminal device is The charging device handshake is successful, that is, the terminal device is located in the preset area of the charging area. It is also possible to detect the distance between the terminal device and the charging area of the charging device. For example, when the distance is less than a certain value, it can be determined that the terminal device and the charging device have successfully shaken hands.

Among them, if the terminal device and the charging device successfully shake hands, it can be determined that the terminal device is already located in the charging area of the charging device. At this time, the first magnet can be controlled to work at the first power so that the first magnet generates a magnet and has a magnetic attraction. Adsorption force, and can magnetically attract the second magnet set on the charging device, and based on the principle of magnetic adsorption and alignment, to achieve the adsorption and alignment of the terminal device and the charging device, and make the first charging coil on the terminal device and The second charging coil on the charging device achieves the purpose of adsorption and alignment, thereby improving the charging efficiency of the battery of the terminal device by the charging device.

Wherein, the first magnet can be controlled to work with a larger first power to increase the magnetic attraction force of the first magnet to the second magnet, so that the first charging coil and the second charging coil can be fully aligned.

Moreover, the magnetic attraction of the first magnet and the second magnet can not only achieve the purpose of adsorption and alignment, but also reduce the gap between the charging device and the terminal device, shorten the power transmission distance, and improve the power transmission efficiency.

Wherein, the relative distance between the geometric center of the first charging coil and the first magnet is equal to the relative distance between the geometric center of the second charging coil and the second magnet, and the second magnet on the charging device corresponds to the distance between the first magnet on the terminal device Location settings.

Step 402: Charge the battery of the terminal device based on the power of the terminal device.

In this step, the power of the terminal device can be detected to determine whether it is necessary to charge the battery of the terminal device. If the power is higher than a certain value, in order to avoid full charging, the terminal device may not be charged temporarily to extend the battery life; if The power level is low, and the battery of the terminal device is charged in order to facilitate the subsequent use of the user.

In this way, by determining whether to charge the terminal device based on the power of the terminal device, unnecessary charging actions can be effectively reduced, thereby extending the service life of the battery.

Moreover, by magnetic adsorption and alignment, the alignment of the first charging coil and the second charging coil can be effectively improved, thereby improving the power transmission efficiency of the charging device to the terminal device, thereby improving the charging efficiency of the terminal device.

It should be noted that if there is no automatic alignment function between the terminal device and the charging device, conventional wireless charging is performed.

Optionally, the charging the battery of the terminal device based on the power of the terminal device includes: obtaining the power of the terminal device; if the power is less than the first power, sending to the charging device The first information, the first information is used to instruct the charging device to transmit electrical energy to the terminal device; if the electrical energy is greater than the second electrical energy, the second information is sent to the charging device, and the second information is used Instructing the charging device to stop transmitting electric energy to the terminal device; wherein the first electric power is less than the second electric power.

In this embodiment, by determining whether to charge the terminal device based on the power of the terminal device, unnecessary charging actions can be effectively reduced, thereby prolonging the service life of the battery.

Among them, the power detector of the terminal device can detect the power of the terminal device, and when the detected power is less than the first power, the terminal device is charged; during the charging process, if the power of the terminal device is detected to reach Rated power, then stop charging the terminal device. After the charging of the terminal device is interrupted, when the electric power is less than the rated electric power but greater than the second electric power, the terminal device is not charged, thereby avoiding continuous charging of the terminal device. Only when the power of the terminal device is less than the first power again, the terminal device is restarted to charge.

Optionally, after the battery of the terminal device is charged based on the power of the terminal device, the method further includes: interrupting the first magnet when it is detected that the terminal device is successfully unlocked The magnetic attraction force between the first magnet and the second magnet; when it is detected that the terminal device has failed to unlock, the magnetic attraction force between the first magnet and the second magnet is increased.

In this embodiment, fingerprint information or facial feature information can be detected, and the detected fingerprint information or facial feature information can be compared with pre-stored unlocking information (including pre-stored fingerprint information or pre-stored facial feature information) Match, if the match is successful, it is determined that the unlocking is successful; if the match fails, it is determined that the unlocking has failed.

Wherein, interrupting the magnetic attraction force between the first magnet and the second magnet refers to terminating the magnetic attraction force of the first magnet to the second magnet. If the unlocking is successful, the power supply to the first magnet can be interrupted. If the second magnet is also energized, the power supply to the second magnet can also be interrupted to release the magnetic attraction between the first magnet and the second magnet. The user takes away the terminal device; if the unlocking fails, it can be determined that the current unlocking object is not the owner of the terminal device. At this time, the magnetic attraction between the first magnet and the second magnet can be increased to prevent non-owner users Take away the terminal equipment.

Among them, if the number of unlock failures exceeds the preset number of times, an alarm can be issued to warn the currently unlocked user. At the same time, it can also send reminders to other bound devices of the owner, and it can also start the camera to collect the video recording of the currently unlocked user. , Retain evidence. Optionally, the preset number of times can be set to 2 times, 3 times, etc., and the setting of the preset number of times can be set according to the user's habits.

In this way, by encrypting the terminal device, the problem of the terminal device being taken away by a stranger during the charging process can be effectively prevented; moreover, by adding encryption and unlocking during the charging process, the user's operating experience can also be improved.

Optionally, during the adsorption and alignment process of the terminal device and the charging device, the adsorption and alignment time of the terminal device and the charging device can be set. For example, when the adsorption and alignment time is set to 1 second, after the second magnet is controlled to work at the first current for 1 second, it is determined that the charging device and the terminal device are aligned, and then the adsorption current of the second magnet is reduced to reduce The unit energy consumption of the second magnet during the charging process of the terminal device.

For example, when the charging device and the terminal device are adsorbed _{and aligned, the magnitude of the working current required by the second magnet is I 1} , and after the charging device and the terminal device are aligned, the magnitude of the working current required by the second magnet Is I ₂ , where I _{2 is} smaller than I ₁ , thereby reducing the unit energy consumption of the second magnet during charging.

Optionally, the information interaction between the charging device and the terminal device can be through QR code scanning verification, Bluetooth communication, WIFI communication, NFC communication, etc., as long as the information interaction between the charging device and the terminal device can be realized.

Optionally, for unlocking encryption during the charging process, the encrypted unlocking information may be digital password information, facial feature information, voice information, fingerprint information, and so on.

Optionally, during the magnetic adsorption and alignment of the terminal device and the charging device, the operating power of the first magnet can also be determined by determining whether the remaining power of the terminal device can satisfy the first magnet to perform a strong adsorption and alignment. Among them, when the power of the terminal device can be set to the preset power, the power of the terminal device can just meet the first magnet to perform a strong adsorption and alignment, and realize the alignment of the first charging coil and the second charging coil, and improve the terminal device The charging efficiency.

Wherein, when the power of the terminal device is lower than the preset power, it means that the remaining power of the terminal device is not enough to perform a strong adsorption and alignment. At this time, the first magnet can be controlled to work at the first power whose power is the first preset power value, so that the first magnet has a certain magnetic attraction force. Moreover, in this case, the charging device can also send first information. The first information is used to indicate that the second magnet, which is an electromagnet, operates at a power whose power is the third preset power value. Set the power value to be greater than the first preset power value, that is, the second magnet produces a larger magnetic attraction force, so that a strong adsorption and alignment between the second magnet and the first magnet is performed to realize the first charging coil and the second The purpose of charging coil alignment.

Wherein, when the power of the terminal device is higher than or equal to the preset power, the first power is set to the second preset power value, so that the first magnet works with the first power whose power is the second preset power value , So that the first magnet and the second magnet can perform a strong adsorption and alignment to achieve the purpose of aligning the first charging coil and the second charging coil.

It should be noted that if the handshaking between the terminal device and the charging device fails, the automatic alignment function is not performed, and only ordinary wireless charging is performed.

In the wireless charging method of the embodiment of the present disclosure, the first magnet is controlled to work at the first power when the terminal device and the external charging device are successfully handshaking, and the first magnet is used for the terminal device and the external charging device. The charging device performs adsorption and alignment, and the charging device is provided with a second magnet at a position corresponding to the first magnet; and based on the power of the terminal device, the battery of the terminal device is charged. In this way, by determining whether to charge the terminal device based on the power of the terminal device, unnecessary charging actions can be effectively reduced, thereby prolonging the service life of the battery; moreover, by magnetic adsorption and alignment, the first charging coil and the second charging coil can be effectively improved. The alignment of the charging coil improves the power transmission efficiency of the charging device to the terminal device, thereby improving the charging efficiency of the terminal device.
