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:
In the step, one of the first device and the second device is a terminal device, the other is a charging device, and the handshake between the first device and the second device is successful, namely, the handshake between the terminal device and the charging device is successful.
When the terminal device is located in a charging area of the charging device, the terminal device or the magnet change condition detected by the charging device can be used, and when a certain condition is met under the detected magnetic field change condition, the terminal device and the charging device can be determined to handshake successfully, namely the terminal device is located in a preset area of the charging area. The handshake between the terminal device and the charging device can be determined to be successful by detecting the distance between the terminal device and the charging region of the charging device, for example, when the distance is smaller than a certain value.
The first equipment and the second equipment are successfully handshaking, the terminal equipment can be determined to be located in a charging area of the charging equipment, at the moment, the first magnet can be controlled to work with first power, so that the first magnet has magnetic adsorption force, magnetic adsorption is carried out on the second magnet arranged on the second equipment, the first equipment and the second equipment are subjected to adsorption alignment based on the principle of magnetic adsorption alignment, and the first charging coil on the first equipment and the second charging coil on the second equipment achieve the aim of adsorption alignment, so that the charging efficiency of the charging equipment to a battery of the terminal equipment is improved.
The first magnet can be controlled to work with larger first power so as 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, through the magnetic attraction of the first magnet and the second magnet, the purpose of attraction alignment can be achieved, the gap between the charging equipment and the terminal equipment can be reduced, the transmission distance of electric energy is shortened, and the transmission efficiency of the electric energy is 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 is arranged corresponding to the position of the first magnet on the terminal device.
And step 402, after the first device and the second device are aligned in an adsorption mode, electric energy is transmitted 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 equipment is terminal equipment and the second equipment is charging equipment, the electric energy transmitted by the second charging coil can be received through the first charging coil, and the battery of the terminal equipment is charged; otherwise, 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.
In the step, the electric energy data of the other side can be obtained through a communication protocol of the terminal equipment and the charging equipment. For example, when the first device is a terminal device, the unit electric energy output 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 amount of the terminal device can be obtained, and the unit electric energy output amount of the charging device can be obtained, so that the electric energy transmission efficiency of the first device is the ratio of the unit electric energy receiving amount to the unit electric energy output amount.
And step 404, if the electric energy transmission efficiency is lower than the preset transmission efficiency, controlling the first magnet to work with the second power and perform adsorption alignment, and after the first equipment and the second equipment perform adsorption alignment again, continuing to charge the battery of the terminal equipment.
In this step, if the power transmission efficiency of the first device is lower than the preset transmission efficiency, it indicates that the best alignment position between the first device and the second device cannot be achieved, at this time, the first magnet may be controlled to work with a larger second power, and adsorption alignment is performed again, so as to achieve realignment of the first device and the second device, and provide an alignment degree between the first charging coil of the first device and the second charging coil of the second device, so as to improve the power transmission efficiency between the first charging coil and the second charging coil. And after the first equipment and the second equipment are subjected to adsorption alignment again, the battery of the terminal equipment is continuously charged.
Wherein the power value of the second power is larger than the power value of the first power.
It should be noted that, during the alignment of the first device and the second device, the power output of the charging device may be temporarily interrupted.
The step 404 is performed during a continuous process until the power transmission efficiency is higher than the predetermined power transmission efficiency.
Like this, through in the charging process, through obtaining electric energy transmission efficiency to under the lower circumstances of electric energy transmission efficiency, through controlling first equipment and second equipment and carrying out powerful absorption counterpoint again, with the alignment degree that improves first charging coil and second charging coil, and then improve electric energy transmission efficiency between first charging coil and the second charging coil, in order to reach the purpose that improves the charging 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 with the first power, the method further includes: detecting the electric quantity of the terminal equipment; if the electric quantity is lower than the 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 power of the terminal device can satisfy that the first magnet performs one-time strong adsorption alignment. When the electric quantity of the terminal equipment is preset, the electric quantity of the terminal equipment can just meet the requirement that the first magnet is subjected to one-time strong adsorption alignment, alignment of the first charging coil and the second charging coil is realized, and the charging efficiency of the terminal equipment is improved.
When the electric quantity of the terminal equipment is lower than the preset electric quantity, the residual electric quantity of the terminal equipment is insufficient to perform one-time strong adsorption alignment. At this time, the first magnet can be controlled to work with the first power of which the power is a first preset power value, so that the first magnet has certain magnetic attraction force. In this case, the charging device may send first information, where the first information is used to indicate that the second magnet that is the electromagnet works with the power of the 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 strong attraction alignment is performed between the second magnet and the first magnet for one time, so as to achieve the purpose of aligning the first charging coil and the second charging coil.
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 a second preset power value, so that the first magnet works with the first power with the power of the second preset power value, and the first magnet and the second magnet are subjected to one-time strong adsorption alignment, so that the aim of aligning the first charging coil and the second charging coil is fulfilled.
Optionally, if the power transmission efficiency is lower than the preset transmission efficiency, the first magnet is controlled to work with a second power and perform adsorption alignment, and after the first device and the second device perform adsorption alignment again and then charge the battery of the terminal device, the method further includes: interrupting the magnetic attraction force between the first magnet and the second magnet when the first device is detected to be successfully unlocked; and increasing the magnetic attraction force between the first magnet and the second magnet when the first device unlocking failure is detected.
In this embodiment, the fingerprint information or the face feature information may be detected, and based on the detected fingerprint information or the face feature information, the detected fingerprint information or the face feature information may be compared with pre-stored unlocking information (including pre-stored fingerprint information or pre-stored face feature information), and if the matching is successful, the unlocking is determined to be successful; 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 electrified, the power supply to the second magnet can be interrupted at the same time, so that the magnetic attraction between the first magnet and the second magnet is relieved, and a user can take away the terminal equipment; if unlocking fails, it can be determined that the current unlocking object is not the owner of the terminal device, and at this time, the non-owner user can be prevented from taking away the terminal device by increasing the magnetic attraction between the first magnet and the second magnet.
When the magnetic attraction force between the first magnet and the second magnet is increased, the purpose of preventing the terminal equipment from being taken away can be achieved by increasing the working power of the first magnet and/or increasing the working power of the second magnet and increasing the magnetic attraction force between the first magnet and the second magnet.
If the unlocking failure times exceed the preset times, the current unlocking user can be warned by sending out an alarm, meanwhile, reminding information can be sent to other binding equipment of the owner, and a camera can be started to collect video recordings of the current unlocking user, so that evidence is reserved. Alternatively, the preset times may be set to 2 times, 3 times, or the like, and the setting of the preset times may be set according to habits of the user.
Thus, the problem that the terminal equipment is taken away by strangers in the charging process can be effectively prevented by encrypting the first equipment; in addition, encryption unlocking is added in the charging process, so that the operation experience of a user can be improved.
Optionally, in the adsorption alignment process of the first device and the second device, the 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 for 1 second with the first current, 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 that the unit energy consumption of the first magnet in the charging process of the terminal device is reduced.
For example, when the first device and the second device are subjected to adsorption alignment, the working current required by the first magnet is I 1 And after the first device and the second device are aligned by adsorption, the working current required by the first magnet is I 2 Wherein I 2 Less than I 1 Thereby reducing the unit energy consumption of the first magnet in the charging process.
Optionally, the information interaction between the first device and the second device may be through two-dimensional code scanning verification, bluetooth communication, WIFI communication, NFC communication, etc., so long as the information interaction between the first device and the second device can be achieved.
Alternatively, for unlocking encryption of the charging process, the encrypted unlocking information may be digital password information, face feature information, voice information, fingerprint information, and the like.
According to the wireless charging method, when handshake between the first device and the external second device is successful, the first magnet is controlled to work with first power, the first magnet working with the first power is used for adsorption alignment between the first device and the second device, the second magnet is arranged at the position of the second device corresponding to the first magnet, one of the first device and the second device is terminal equipment, and the other is charging equipment; after the first equipment and the second equipment are in adsorption alignment, electric energy is transmitted through the first charging coil, so that the charging equipment charges a battery of the terminal equipment; 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 with the second power, performing adsorption alignment, and continuously charging a 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 larger than the power value of the first power. Therefore, in the charging process, the electric energy transmission efficiency is obtained, and under the condition of lower electric energy transmission efficiency, the first equipment and the second equipment are controlled to perform strong adsorption alignment again, so that the alignment degree of the first charging coil and the second charging coil is improved, the electric energy transmission efficiency between the first charging coil and the second charging coil is improved, and the purpose of improving the charging efficiency of the terminal equipment is achieved.
