[0046] In order to make the technical problems, technical solutions and beneficial effects solved by the embodiments of the present invention clearer, the following further details the embodiments of the present invention with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0047] In a core concept of an embodiment of the present invention, for the existing wireless charging process, the user needs to manually adjust the placement position of the terminal, otherwise the wireless charging power will be affected. Even for a terminal and a mobile power supply equipped with a magnetic attraction component, the user also needs to place them in a certain position and then adjust the position, so that the two can achieve the effect of magnetic attraction wireless charging. In an application scenario of an embodiment of the present invention, the mobile power supply can be fixed under a table (a fixed object) to achieve wireless charging through the air or weak identification wireless charging. Specifically, by controlling the magnetic force of some magnetic attraction points in the first magnetic attraction charging dot matrix on the mobile power supply, the terminal with a matching second magnetic attraction charging dot matrix can be "attracted" to the position with the highest wireless charging power, without the need for manual adjustment of the wireless charging position.

[0048] Refer to Figure 1, showing a schematic diagram of an embodiment of a magnetic attraction control method for a wireless charging mobile power supply according to an embodiment of the present invention. The mobile power supply is electrically connected to an external component, and the mobile power supply is provided with a first magnetic attraction charging dot matrix; the first magnetic attraction charging dot matrix is connected to the external component through a wire, and the terminal is provided with a second magnetic attraction charging dot matrix. The mobile power supply is matched and connected to the second magnetic attraction charging dot matrix of the terminal through the first magnetic attraction charging dot matrix. Specifically, the following steps may be included:

[0049] Step S101, when the mobile power supply is placed under a fixed object and the terminal is placed above the mobile power supply, obtain the initial charging power data of the terminal;

[0050] In an embodiment of the present invention, the wireless charging system includes a mobile power supply, a terminal, and an external component. Among them, the external component may refer to a charging wire including multiple different types of interfaces. For example, a charging wire including a type-c interface and a 220v power supply interface. Further, the mobile power supply is provided with a first magnetic attraction charging dot matrix, as Figure 2 shown, the first magnetic attraction charging dot matrix includes a plurality of magnet attraction points arranged in different dispersions. The magnet attraction points are electromagnetic conductors, and the electromagnetic conductors may be silicon steel magnets, ferrite magnets, etc. The embodiment of the present invention does not limit this too much. The magnet attraction points of the first magnetic attraction charging dot matrix are respectively connected to the wire and the external component. In a preferred embodiment, the magnet attraction points of the first magnetic attraction charging dot matrix may also be connected to the battery cell and the controller of the mobile power supply, and the magnetic attraction force magnitude and the magnetic attraction area position of the magnet attraction points are controlled by the current of an external power supply or the internal power supply of the mobile power supply.

[0051] In terms of structure, the magnet attraction point may further include a conductive coil wound around the electromagnetic conductor. The embodiment of the present invention does not limit the types and quantities of the structural components of the magnet attraction point too much.

[0052] Regarding the distribution shape of the magnet attraction points of the first magnetic attraction charging dot matrix, it may be circular, square, heart-shaped, triangular, etc. The embodiment of the present invention does not limit this too much; and regarding the dispersion arrangement method of the magnet attraction points of the first magnetic attraction charging dot matrix, it may be any equidistant or non-equidistant dispersion arrangement method. The embodiment of the present invention does not limit this too much; specifically applied to the embodiment of the present invention, the terminal and the mobile power supply may be provided with components such as a wireless charging coil, as Figure 3 shown, the wireless charging area may coincide with the center of the first magnetic attraction charging dot matrix to achieve the best wireless magnetic attraction charging effect.

[0053] Specifically applied to the embodiment of the present invention, when the mobile power supply is placed under a fixed object and the terminal is placed above the mobile power supply, obtaining the initial charging power data of the terminal includes:

[0054] When the mobile power supply is set under a fixed object and the terminal is placed above the mobile power supply, the mobile power supply is controlled to trigger a wireless charging signal, and the terminal receives the wireless charging signal to start the wireless charging process. The initial charging power data of the terminal is measured and obtained. The second magnetic adsorption charging dot matrix set for the terminal can be a common magnet material, and the embodiments of the present invention do not limit this too much.

[0055] In the embodiments of the present invention, the fixed object can be a table, such as a wooden table. The mobile power supply is set under the wooden table, and the terminal can be placed above the mobile power supply, such as Figure 4 the initial placement position of the terminal shown by the solid line frame as shown. At this time, the terminal detects that the mobile power supply triggers a wireless charging signal and starts the wireless charging process. The terminal can obtain the initial charging power data of the wireless charging. If the terminal is in Figure 4 the initial placement position of the solid line frame as shown, the terminal will enter the small-power wireless charging situation, and the initial charging power data of the terminal will be less than the normal wireless charging power.

[0056] Step S102: Identify the relative position information between the terminal and the mobile power supply according to the initial charging power data, and convert the relative position information into magnetic adsorption current control information.

[0057] In the embodiments of the present invention, the relative position information between the terminal and the mobile power supply can be identified according to the initial charging power data, and then the relative position information is converted into the magnetic adsorption current control information of the first magnetic adsorption charging dot matrix, and the terminal is moved to the optimal wireless charging position by relying on the magnetic attraction force. That is, when the initial charging power data is less than the normal wireless charging power, the relative position information is considered to include the relative distance and the placement direction.

[0058] Specifically applied to the embodiments of the present invention, the identifying the relative position information between the terminal and the mobile power supply according to the initial charging power data and converting the relative position information into magnetic adsorption current control information includes:

[0059] Establish a mapping relationship between the wireless charging power, the relative distance, and the magnetic adsorption current control information in advance; the magnetic adsorption current control information includes the input current at the position of increasing the magnetic force point and the input current at the position of decreasing the magnetic force point;

[0060] Query the mapping relationship according to the initial charging power data to obtain specific relative distance information;

[0061] Determine the magnetic adsorption point positions in the first magnetic adsorption charging dot matrix within the specific relative distance information as the positions of increasing the magnetic force points, and increase the input current at the positions of increasing the magnetic force points, so as to increase the magnetic attraction force at the positions of increasing the magnetic force points;

[0062] Among them, polling is performed on the magnetic point areas in multiple directions. If the wireless charging power of the terminal increases, the polling of the magnetic point area is stopped, and the current magnetic point area is determined to be the increased magnetic point position. The specific relative distance information refers to the distance from the edge of the increased magnetic point position to the ideal edge of the terminal charging.

[0063] First, if Figure 5 As shown, in the first step of determining the relative position information of the terminal and the mobile power supply, a polling operation of increasing the input current in the magnetic charging point area is performed on the first magnetic charging point array to determine the initial placement direction of the terminal, as shown in the following sequence: Figure 5 As shown in sub-figure a in FIG, the input current of the magnetic attraction point area on the right is increased, such as Figure 5 As shown in sub-figure b in FIG, the input current of the upper magnetic attraction point area is increased, such as Figure 5 As shown in sub-figure c in FIG, the input current of the lower magnetic attraction point area is increased, such as Figure 5 As shown in sub-figure d in FIG, for the increased input current in the magnetic attraction point area on the left, the relative position of the terminal and the mobile power supply is determined according to the degree of change in the charging power data of the terminal. For example, when the terminal is placed in Figure 4 The placement of the solid line frame shown (i.e. Figure 5 When the terminal is in the sub-diagram a), the terminal will be affected by the magnetic attraction point after the current is increased. Figure 4 If the terminal moves in the direction shown, the charging power data of the terminal will continue to rise. Figure 5 When the terminal is attached to the first magnetic charging dot matrix more deeply, the charging power data will not be changed, thereby determining the initial relative position of the terminal, that is, the initial placement direction;

[0064] Second, in the embodiment of the present invention, a mapping relationship between wireless charging power, relative distance, and magnetic current control information is pre-established, and then the relative distance between the terminal and the mobile power supply is determined according to the measured wireless charging power, and then the magnetic current control information is obtained through relative distance query.

[0065] For example, the mapping table of wireless charging power, the relative distance between the terminal and the mobile power supply, and the magnetic current control information is as follows:

[0066]

[0067] If the relative distance B1 between the terminal and the mobile power supply and the magnetic attraction current control information C1 are obtained by querying the mapping relationship according to the initial charging power data A1, then the input current at the position of the increased magnetic force point is controlled according to the magnetic attraction current control information C1, that is, the input current is increased to the magnetic attraction current control information C1. The positions other than the position of the increased magnetic force point are the positions of the decreased magnetic force points, and the input current at the position of the decreased magnetic force point is reduced to D1, and the relative distance B1 is determined as the specific relative distance information.

[0068] Step S103: Control the magnetic attraction force distribution of the first magnetic attraction charging dot matrix through the magnetic attraction current control information, match the second magnetic attraction charging dot matrix of the terminal with the first magnetic attraction charging dot matrix, and perform wireless charging operation of the terminal.

[0069] The controlling the magnetic attraction force distribution of the first magnetic attraction charging dot matrix through the magnetic attraction current control information, matching the second magnetic attraction charging dot matrix of the terminal with the first magnetic attraction charging dot matrix, and performing wireless charging operation of the terminal includes:

[0070] Determine the magnetic attraction point positions in the first magnetic attraction charging dot matrix other than the specific relative distance information as the positions of the decreased magnetic force points, and reduce the input current at the positions of the decreased magnetic force points;

[0071] Increase the input current at the position of the increased magnetic force point, move the terminal to the matching position of the first magnetic attraction charging dot matrix through the second magnetic attraction charging dot matrix, and perform wireless charging operation of the terminal.

[0072] Such as Figure 4 As shown, determine the magnetic attraction point positions in the first magnetic attraction charging dot matrix other than the specific relative distance information as the positions of the decreased magnetic force points, and reduce the input current at the positions of the decreased magnetic force points to form the magnetic attraction force distribution of the first magnetic attraction charging dot matrix.

[0073] In the embodiment of the present invention, the performing the wireless charging operation of the terminal includes: superimposing the impedance of the first magnetic attraction charging dot matrix and the wireless charging transmitting end to obtain an equivalent total impedance; calculating the magnetic attraction control power and the wireless charging power through the equivalent total impedance; controlling the wireless charging operation of the terminal according to the magnetic attraction control power and the wireless charging power.

[0074] The calculation method of the equivalent total impedance is as follows:

[0075] Z = ω 2 M / R + r1;

[0076] Further, the calculation methods of the magnetic attraction control power and the wireless charging power are as follows:

[0077] P Q = (P1 - P2)Z;

[0078] Among them, Z represents the equivalent total impedance, ω is the angular frequency of the power supply, M is the mutual inductance coefficient of the wireless charging transmitting end, and R is the internal resistance of the wireless charging transmitting end; r1 is the internal resistance of the first magnetic adsorption charging lattice, and P Q is the sum of the magnetic adsorption control power and the wireless charging power. If the magnetic adsorption control process has been completed, that is, when the relative position of the terminal and the mobile power supply is the optimal position, then P2 is zero, and P Q = P1Z, and only the wireless charging operation of the terminal is controlled according to the wireless charging power. P2 is the actual power of the first magnetic adsorption charging lattice, and P1 is the actual power of the wireless charging transmitting end;

[0079] In an embodiment of the present invention, the mobile power supply is electrically connected to an external component, and the mobile power supply is provided with a first magnetic adsorption charging lattice; the first magnetic adsorption charging lattice is connected to the external component through a wire, the mobile power supply is matched and connected to the terminal, and the terminal is provided with a second magnetic adsorption charging lattice; the magnetic adsorption control method of the wireless charging mobile power supply includes: when the mobile power supply is disposed under a fixed object and the terminal is placed above the mobile power supply, the initial charging power data of the terminal is obtained; the relative position information between the terminal and the mobile power supply is identified according to the initial charging power data, and the relative position information is converted into magnetic adsorption current control information; the magnetic adsorption force distribution of the first magnetic adsorption charging lattice is controlled through the magnetic adsorption current control information, the second magnetic adsorption charging lattice of the terminal is matched with the first magnetic adsorption charging lattice, the wireless charging operation of the terminal is performed, and the terminal with the matched second magnetic adsorption charging lattice is controlled to move to the position with the highest wireless charging power, without the need for manual adjustment of the wireless charging position, improving the convenience and speed of wireless charging.
