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

Step 401: In the case that the handshake between the charging device and the external terminal device is successful, acquire the first unlocking information collected by the charging device.

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 a certain condition, it can be determined that the terminal device is connected to the charging device. The handshake of the charging device is successful, that is, the terminal device is located in the preset area of the charging area. The distance between the terminal device and the charging area of the charging device can also be detected. 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.

The first unlocking information may be fingerprint information, face feature information, pupil information, and the like. The user's fingerprint information can be collected through a fingerprint module disposed on the charging device; or, the user's facial feature information or pupil information, etc. can be collected through a camera disposed on the charging device.

Step 402: If the first unlocking information is successfully matched with the preset unlocking information, control the second magnet to work with the first power.

In this step, the preset unlocking information may be unlocking information (such as fingerprint information, face feature information, pupil information, etc.) pre-stored on the charging device by the owner of the terminal device. If the first unlocking information is successfully matched with the preset unlocking information, it can be indicated that the terminal device is controlled by the owner. Then, the second magnet can be controlled to work with the first power, so that the second magnet generates a magnetic field and has a magnetic adsorption force, and the first magnet set on the terminal device is magnetically adsorbed, and based on the principle of magnetic adsorption alignment , so that the charging device and the terminal device can be adsorbed and aligned, and the second charging coil of the charging device and the first charging coil of the terminal device can be adsorbed and aligned, thereby improving the charging efficiency of the charging device to the terminal device.

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

Moreover, through the magnetic adsorption of the first magnet and the second magnet, not only the purpose of adsorption and alignment can be achieved, but also the gap between the charging device and the terminal device can be reduced, the transmission distance of electric energy can be shortened, and the transmission efficiency of electric energy can be improved.

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 first magnet on the terminal device. Location settings.

Step 403: After the charging device and the terminal device are adsorbed and aligned, transmit power to the terminal device through the second coil of the charging device, so that the charging device can charge the battery of the terminal device .

In this step, the terminal device is provided with a first charging coil, and the charging device is provided with a second charging coil, and electrical energy can be transmitted to the first charging coil through the second charging coil to charge the battery of the terminal device.

Moreover, if the charging device starts to charge the battery of the terminal device, the second indicator light can also be controlled to light up, so as to remind the user that the terminal device has entered the charging state.

In this way, by collecting and identifying the unlocking information of the user to determine whether to perform the charging operation on the terminal device, the safety and interactivity of the charging process can be effectively improved; The two magnets are adsorbed and aligned, so that the first charging coil on the terminal device is aligned with the second charging coil on the charging device, which can also improve the power transmission efficiency of the charging device to the terminal device, thereby improving the charging efficiency of the terminal device. .

Optionally, after the charging device and the terminal device are adsorbed and aligned, electric energy is transmitted to the terminal device through the second coil of the charging device, so that the charging device can have a good effect on the terminal device. After the battery is charged, the method further includes: controlling the second indicator light to emit light of the first color.

In this embodiment, after the terminal device enters the charging state, the second indicator light of the charging device can be controlled to emit light of the first color to remind the user.

Among them, before the terminal device and the charging device perform handshake communication, the unlocking information of the host, such as fingerprint information or face feature information, can be stored on the charging device, and after the host successfully stores the unlocking information, the second indicator light can emit Light of the fourth color; then when the charging device enters the state of starting to charge the terminal device, the light color of the second indicator light can be controlled to be converted from the fourth color to the first color, such as charging yellow to green.

Optionally, after controlling the second indicator light to emit light of the first color, the method further includes: acquiring second unlocking information collected by the charging device; If the preset unlocking information is successfully matched, the magnetic attraction force between the first magnet and the second magnet is interrupted, and the light color of the second indicator light is controlled to be converted from the first color to the second color; If the matching of the second unlocking information and the preset unlocking information fails, the magnetic attraction force between the first magnet and the second magnet is increased, and the light color of the second indicator light is controlled from The first color is converted into a third color.

In this embodiment, fingerprint information or face feature information can be collected, and the collected fingerprint information or face feature information can be compared with pre-stored unlocking information (including pre-stored fingerprint information or pre-stored face feature information). If the match is successful, it is determined that the unlocking is successful; if the matching fails, it is determined that the unlocking fails.

Among them, if the unlocking is successful, the power supply to the second magnet is interrupted, and if the first magnet is also powered on, the power supply to the first magnet can also be interrupted at the same time, so as to release the magnetic attraction force between the first magnet and the second magnet, So that the user can take away the terminal device; if the unlocking fails, it can be determined that the current unlock object is not the owner of the terminal device. At this time, the magnetic attraction force between the first magnet and the second magnet can be increased to prevent non-owners The user removes the terminal device.

Among them, in the case of successful unlocking, the light color of the second indicator light can be controlled to be converted from the first color to the second color, such as from yellow to blue, to remind the user of the magnetic attraction between the terminal device and the charging device. If unlocked, the user can take away the terminal device; in the case of failure to unlock, the light color of the second indicator light can be controlled to change from the first color to the third color, such as changing from yellow to red, to warn non-owner users, Prevent terminal equipment from being taken away by non-owner users. Through the setting of the indicator light and the change of the color of the indicator light, the user can be reminded of the specific state of the charging device during the charging process, and the charging experience of the user can be improved.

Wherein, when increasing the magnetic attraction force between the first magnet and the second magnet, the working power of the first magnet and/or the working power of the second magnet can be increased, and the first magnet and /or the magnetic adsorption force of the second magnet, so as to increase the magnetic adsorption force between the first magnet and the second magnet, so as to prevent the terminal device from being taken away.

Among them, if the number of unlocking failures exceeds the preset number of times, an alarm can be issued to warn the current unlocking user, and at the same time, reminder information can be sent to other bound devices of the host, and the camera can also be started to collect the video recording of the currently unlocked user. , keep the evidence. Optionally, the preset number of times may be set to 2 times, 3 times, etc., and the setting of the preset number of times may be set according to the user's habit.

In this way, by encrypting the charging device, it can effectively prevent the terminal device from being taken away by strangers during the charging process; moreover, by adding encryption and unlocking during the charging process, the user's operating experience can also be improved.

Optionally, before controlling the second magnet to work with the first power, the power of the terminal device can also be obtained, and the size of the first power can be controlled according to the power level of the terminal device; if it is detected that the power of the terminal device is lower than the preset power If the power is set, the second magnet can be controlled to work with a larger power, and at the same time, the first magnet of the terminal device can be controlled to work with a smaller power, so as to realize the magnetic adsorption alignment of the first magnet and the second magnet; if detected When the power of the terminal device is higher than or equal to the preset power, both the second magnet and the first magnet can be controlled to work at normal working power to satisfy the magnetic adsorption alignment of the first magnet and the second magnet. Thus, the purpose of aligning the first charging coil of the terminal device and the second charging coil of the charging device is achieved.

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

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

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

It should be noted that the first indicator light of the terminal device can also be controlled to emit lights of different colors to remind the user of the state of the terminal device, such as the charging state, abnormal state or ready state, etc. The implementation method is different from that of the charging device. similar, and will not be repeated here.
