As shown in fig. 4, an embodiment of the present invention provides a wireless charging method applied to a first device, where the first device includes a first charging coil and a first magnet, and the first magnet is an electromagnet, and the method includes:
Step 401, controlling the first magnet to work at a first power when the first device successfully handshakes with an external second device.
In this step, one of the first device and the second device is a terminal device, the other is a charging device, and the first device and the second device successfully handshake, that is, the terminal device and the charging device successfully handshake.
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 can be used, and when the detected magnetic field change condition meets a certain condition, the handshake success between the terminal device and the charging device can be determined, namely 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.
The first device and the second device successfully handshake, and then the terminal device can be determined to be located in a charging area of the charging device, and at this time, the first magnet can be controlled to work with first power, so that the first magnet has magnetic adsorption force, magnetic adsorption is performed on a second magnet arranged on the second device, and based on the principle of magnetic adsorption alignment, the first device and the second device are subjected to adsorption alignment, and a first charging coil on the first device and a second charging coil on the second device achieve the purpose of adsorption alignment, so that the charging efficiency of the charging device on a battery of the terminal device is improved.
Wherein, can work with great first power through controlling first magnet to increase the magnetic attraction of first magnet to the second magnet, thereby make first charging coil and second charging coil reach the purpose of full alignment.
Moreover, the magnetic force adsorption of the first magnet and the second magnet can achieve the purpose of adsorption alignment, reduce the gap between the charging equipment and the terminal equipment, shorten the transmission distance of electric energy and improve the transmission efficiency of the electric energy.
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 is arranged corresponding to the position of the first magnet on the terminal device.
step 402, after the first device and the second device are adsorbed and aligned, transmitting electric energy through the first charging coil, so that the charging device charges a battery of the terminal device.
in the step, a first device is provided with a first charging coil, and a second device is provided with a second charging coil; if the first device is a terminal device and the second device is a charging device, the first charging coil can receive electric energy transmitted by the second charging coil, and a battery of the terminal device is charged; on the contrary, if the first device is a charging device and the second device is a terminal device, the electric energy can be transmitted to the second charging coil through the first charging coil so as to charge the battery of the terminal device.
And step 403, acquiring the electric energy transmission efficiency of the first device.
in this step, the electric energy data of the other side can be acquired through the communication protocol of the terminal device and the charging device. For example, when the first device is a terminal device, the unit electric energy output amount of the charging device may be obtained, and the unit electric energy receiving amount of the terminal device itself may be obtained, so that the electric energy transmission efficiency of the first device is a ratio of the unit electric energy receiving amount to the unit electric energy output amount.
similarly, when the first device is a charging device, the unit electric energy receiving quantity of the terminal device can be obtained, and the unit electric energy output quantity of the charging device itself can be obtained, so that the electric energy transmission efficiency of the first device is the ratio of the unit electric energy receiving quantity to the unit electric energy output quantity.
and 404, if the electric energy transmission efficiency is lower than the preset transmission efficiency, controlling the first magnet to work at a second power and perform adsorption alignment, and continuously charging the battery of the terminal device after the first device and the second device perform adsorption alignment again.
In this step, if the power transmission efficiency of the first device is lower than the preset power transmission efficiency, it is indicated that the best alignment position between the first device and the second device cannot be reached, and at this time, the first magnet can be controlled to work with a larger second power, and the adsorption alignment is performed again, so that the realignment of the first device and the second device is realized, the alignment degree of the first charging coil of the first device and the second charging coil of the second device is provided, and the power transmission efficiency between the first charging coil and the second charging coil is further improved. And continuously charging the battery of the terminal equipment after the first equipment and the second equipment are adsorbed and aligned again.
Wherein the power value of the second power is larger than the power value of the first power.
it should be noted that the power output of the charging device may be temporarily interrupted during the alignment of the first device and the second device.
the obtaining of the power transmission efficiency is a continuous process, and generally, until the power transmission efficiency is higher than the preset transmission efficiency, step 404 is executed.
Like this, through in the charging process, through obtaining power transmission efficiency to under the lower condition of power transmission efficiency, carry out the brute force once more through control first equipment and second equipment and adsorb the counterpoint, with the alignment degree that improves first charging coil and second charging coil, and then improve the power transmission efficiency between first charging coil and the second charging coil, in order to reach the purpose that improves the charge efficiency to terminal equipment.
optionally, the first device is a terminal device, the second device is a charging device, and before the controlling the first magnet to operate at the first power, the method further includes: detecting the electric quantity of the terminal equipment; if the electric quantity is lower than a preset electric quantity, setting the power of the first power to be a first preset power value; if the electric quantity is higher than or equal to the preset electric quantity, setting the power of the first power to be a second preset power value; wherein the first preset power value is smaller than the second preset power value.
In this embodiment, the working power of the first magnet may be determined by determining whether the remaining capacity of the terminal device can satisfy the requirement of performing the one-time strong adsorption alignment on the first magnet. Wherein, when can set for terminal equipment's electric quantity for predetermineeing the electric quantity, terminal equipment's electric quantity just in time can satisfy first magnet and carry out once the strong adsorption counterpoint to realize the alignment of first charging coil and second charging coil, improve terminal equipment's charge efficiency.
When the electric quantity of the terminal equipment is lower than the preset electric quantity, the residual electric quantity of the terminal equipment is not enough to perform strong adsorption contraposition once. In this case, the first magnet may be controlled to operate at a first power with a first predetermined power value, so that the first magnet has a certain magnetic attraction force. In addition, in this case, the charging device may further send first information, where the first information is used to indicate that the second magnet, which is an electromagnet, operates with power whose power is a third preset power value, and the third preset power value is set to be greater than the first preset power value, that is, the second magnet generates a larger magnetic attraction force, so that a strong attraction alignment is performed between the second magnet and the first magnet, and the purpose of aligning the first charging coil and the second charging coil is achieved.
When the electric quantity of the terminal equipment is higher than or equal to the preset electric quantity, the first power is set to be the second preset power value, so that the first magnet works with the first power with the power being the second preset power value, the first magnet and the second magnet are subjected to once strong adsorption alignment, and the aim of aligning the first charging coil and the second charging coil is fulfilled.
optionally, if the electric energy transmission efficiency is lower than a preset transmission efficiency, the first magnet is controlled to operate at a second power and perform adsorption alignment, and after the first device and the second device perform adsorption alignment again, and continue to charge the battery of the terminal device, the method further includes: interrupting a magnetic attraction force between the first magnet and the second magnet if the first 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 first 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.
if the unlocking is successful, the power supply to the first magnet is interrupted, if the second magnet is also electrified, the power supply to the second magnet can be interrupted simultaneously, 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.
When the magnetic adsorption force between the first magnet and the second magnet is increased, the working power of the first magnet can be increased, and/or the working power of the second magnet can be increased, and the magnetic adsorption force between the first magnet and the second magnet can be increased by increasing the magnetic adsorption force of the first magnet and/or the second magnet, so that the aim of preventing the terminal device from being taken away is fulfilled.
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 prevented by encrypting the first equipment; moreover, through in the charging process, encryption and unlocking are added, and the operation experience of a user can be improved.
Optionally, in the adsorption alignment process of the first device and the second device, adsorption alignment time of the first device and the second device may 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, the adsorption alignment of the first device and the second device is determined, and then the adsorption current of the first magnet is reduced, so as to reduce the unit energy consumption of the first magnet in the charging process of the terminal device.
For example, when the first device and the second device perform adsorption alignment, the magnitude of the working current required by the first magnet is I1And after the first device and the second device are in adsorption alignment, the magnitude of the working current required by the first magnet is I2Wherein, I2Is less than I1Thereby reducing the unit energy consumption of the first magnet in the charging process.
Optionally, information interaction between the first device and the second device may be performed through two-dimensional code scanning verification, bluetooth communication, WIFI communication, NFC communication, and the like, as long as information interaction between the first device and the second device is 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.
in the wireless charging method of the embodiment of the invention, when the first device successfully handshakes with an external second device, the first magnet is controlled to work at a first power, the first magnet working at the first power is used for performing adsorption alignment on the first device and the second device, the second device is provided with a second magnet at a position corresponding to the first magnet, one of the first device and the second device is a terminal device, and the other is a charging device; after the first device and the second device are adsorbed and aligned, transmitting electric energy through the first charging coil to enable the charging device to charge a battery of the terminal device; acquiring the electric energy transmission efficiency of the first equipment; if the electric energy transmission efficiency is lower than the preset transmission efficiency, controlling the first magnet to work at a second power and perform adsorption alignment, and continuously charging the battery of the terminal equipment after the first equipment and the second equipment perform adsorption alignment again; wherein the power value of the second power is greater than the power value of the first power. Through like this at the charging process, through obtaining power transmission efficiency to under the lower condition of power transmission efficiency, carry out the brute force once more through control first equipment and second equipment and adsorb the counterpoint, with the alignment degree that improves first charging coil and second charging coil, and then improve the power transmission efficiency between first charging coil and the second charging coil, in order to reach the purpose that improves the charge efficiency to terminal equipment.
