As shown in fig. 5, an embodiment of the present invention provides a wireless charging method applied to a charging device, where the charging device includes a driving assembly and a second magnet, where the second magnet is an electromagnet, and the method includes:
Step 501, controlling the driving assembly to drive the second magnet to move to a target position when the charging device successfully handshakes with an external terminal device.
In this step, when the terminal device is located in the charging area of the charging device, the magnet change condition detected by the terminal device or the charging device may be used, and when the detected magnetic field change condition satisfies a certain condition, it may be determined that the handshake between the terminal device and 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 handshake between the terminal device and the charging device is successful.
Under the successful condition of shaking hands at battery charging outfit and terminal equipment, for example when terminal equipment laminates on battery charging outfit's loading face, can control drive assembly drive second magnet and remove to the target location, at the target location, the distance of the first magnet on second magnet and the terminal equipment is less than preset distance to the second magnet carries out magnetic force with first magnet and adsorbs the counterpoint, and then realizes that battery charging outfit's second charging coil aligns with terminal equipment's first charging coil.
step 502, in the target position, controlling the second magnet to work at a first power, and using the second magnet working at the first power for performing adsorption alignment between the charging device and the terminal device.
In the step, at the target position, the second magnet can be controlled to work at the first power, so that the second magnet generates a magnetic field and has a magnetic adsorption force, the magnetic adsorption alignment of the first magnet is realized, and the adsorption alignment of the charging equipment and the terminal equipment is further realized.
Wherein, can be through controlling the second magnet with great first power work, increase the magnetic attraction power of second magnet to first magnet to make first charging coil and second charging coil reach the purpose of full alignment.
Step 503, after the charging device and the terminal device are aligned in an adsorption manner, transmitting electric energy to the first charging coil of the terminal device through the second charging coil of the charging device so as to charge the battery of the terminal device.
in this step, the electric energy may be transmitted to the first charging coil through the second charging coil to realize charging the battery of the terminal device.
like this, through counterpointing the second magnet on with battery charging outfit and the first magnet on the terminal equipment, can make first on the terminal equipment act as the coil and aim at with the second charging coil on the battery charging outfit to improve battery charging outfit to terminal equipment's power transmission efficiency, and then improve the charge efficiency to terminal equipment. Moreover, through setting up mobilizable second magnet, battery charging outfit can charge to the terminal equipment of different models size, the effectual model that enriches terminal equipment.
after the second magnet moves to the target position, the alignment information can be sent to the terminal device, and the alignment information is used for indicating the first magnet of the terminal device to work with the target power, so that the first magnet of the terminal device generates a magnetic field and has magnetic adsorption force, and magnetic adsorption alignment of the first magnet and the second magnet is achieved.
Furthermore, can control first magnet and second magnet and produce the magnetic attraction power simultaneously, and then improve the magnetic attraction power between first magnet and the second magnet, reach the purpose that first charging coil and second charging coil fully aimed at.
Optionally, the controlling the driving assembly to drive the second magnet to move to the target position includes: receiving first information sent by the terminal equipment, wherein the first information carries size information of the terminal equipment; acquiring a first distance that the second magnet needs to move based on the size information; controlling the driving assembly to drive the second magnet to move the first distance so as to move the second magnet to the target position.
in this embodiment, a first distance that the second magnet needs to move may be calculated according to the size information of the terminal device, and then the driving assembly is controlled to drive the second magnet to move the first distance, so that the second magnet moves to the target position, and the distance between the second magnet and the first magnet is within the range that can perform magnetic attraction alignment.
During the handshake communication between the terminal device and the charging device, the charging device may further send the position information of the second magnet and the initial position information of the terminal device on the charging device to the terminal device, so as to improve the accuracy of the calculation of the first distance.
In addition, the information such as the residual capacity of the terminal equipment, the charging frequency information and the like can be acquired, so that the charging process can be optimized according to the historical charging data information of the terminal equipment in the charging process, and the service life of the battery of the terminal equipment is prolonged.
Optionally, after the charging device and the terminal device are aligned in an adsorption manner, the method further includes transmitting electric energy to a first charging coil of the terminal device through a second charging coil of the charging device to charge a battery of the terminal device, and then: interrupting a magnetic attraction force between the first magnet and the second magnet if the charging device is detected to be successfully unlocked; increasing a magnetic attraction force between the first magnet and the second magnet if a failure to unlock the charging device is detected.
In this embodiment, the fingerprint information or the face feature information may be detected, and the detected fingerprint information or face feature information is compared and matched with the pre-stored unlocking information (including the pre-stored fingerprint information or the pre-stored face feature information), and if the matching is successful, the unlocking is determined to be successful; and if the matching fails, determining that the unlocking fails.
Wherein interrupting the magnetic attraction force between the first magnet and the second magnet means terminating the magnetic attraction force of the second magnet to the first magnet. If the unlocking is successful, the power supply to the second magnet can be interrupted, if the first magnet is also electrified, the power supply to the first magnet can be interrupted, so that the magnetic adsorption force between the first magnet and the second magnet is relieved, and a user can take the terminal equipment away; if the unlocking is failed, the current unlocking object is determined to be not the owner of the terminal equipment, and at the moment, the magnetic adsorption force between the first magnet and the second magnet can be increased to prevent the non-owner user from taking away the terminal equipment.
If the unlocking failure times exceed the preset times, the current unlocking user can be warned in an alarm sending mode, meanwhile, the reminding information can be sent to other binding equipment of the owner, the camera can be started to collect the video of the current unlocking user, and the evidence is stored. Optionally, the preset times may be set to 2 times, 3 times, and the like, and the setting of the preset times may be set according to the habit of the user.
Therefore, the problem that the terminal equipment is taken away by a stranger in the charging process can be effectively solved by encrypting the charging equipment; moreover, through in the charging process, encryption and unlocking are added, and the operation experience of a user can be improved.
In addition, the terminal device can be encrypted, and the same effect as that of encrypting the charging device can be achieved, which is not described herein again.
After the terminal device is taken away, the driving mechanism can be controlled to drive the second magnet to move to the initial position or the default position so as to perform adsorption alignment for the next time.
Optionally, in the adsorption alignment process between the terminal device and the charging device, adsorption alignment time between the terminal device and the charging device may be set. For example, when the adsorption alignment time is set to 1 second, after the second magnet is controlled to operate at the first current for 1 second, it is determined that the charging device and the terminal device are in adsorption alignment, and then the adsorption current of the second magnet is reduced, so as to reduce the unit energy consumption of the second magnet in the charging process of the terminal device.
for example, when the charging device and the terminal device perform adsorption alignment, the magnitude of the working current required by the second magnet is I1And after the charging equipment and the terminal equipment are in adsorption alignment, the magnitude of the working current required by the second magnet is I2Wherein, I2Is less than I1Thereby reducing the unit energy consumption of the second magnet in the charging process.
optionally, information interaction between the charging device and the terminal device may be performed through modes such as two-dimensional code scanning verification, bluetooth communication, WIFI communication, NFC communication, and the like, as long as information interaction between the charging device and the terminal device can be achieved.
Optionally, for the unlocking encryption in the charging process, the encryption and unlocking information may be digital password information, face feature information, voice information, fingerprint information, and the like.
According to the wireless charging method, under the condition that the charging equipment successfully handshakes with external terminal equipment, the driving assembly is controlled to drive the second magnet to move to the target position, and the distance between the second magnet and the first magnet on the terminal equipment is smaller than a preset distance; at the target position, controlling the second magnet to work at a first power, wherein the second magnet working at the first power is used for adsorption alignment of the charging equipment and the terminal equipment; after the charging equipment and the terminal equipment are adsorbed and aligned, electric energy is transmitted to the first charging coil of the terminal equipment through the second charging coil of the charging equipment so as to charge the battery of the terminal equipment. Like this through counterpointing the second magnet on with battery charging outfit and the first magnet on the terminal equipment, can make first on the terminal equipment act as the coil and aim at with the second charging coil on the battery charging outfit to improve battery charging outfit to terminal equipment's power transmission efficiency, and then improve the charge efficiency to terminal equipment. Moreover, through setting up mobilizable second magnet, battery charging outfit can charge to the terminal equipment of different models size, the effectual model that enriches terminal equipment.
