[0068] Figure 2 is a block diagram illustrating a schematic configuration of a wireless charging transmitter according to an embodiment of the present disclosure.

[0069] As an example, Figure 2 The figure illustrates a wireless charging transmitter device 10 that can be flexibly configured and effectively adapted to any form of magnetic wireless charging receiver device.

[0070] Reference Figure 2 The wireless charging transmitter 10 includes a plurality of electromagnet units 11, a control unit 12, and a charging module 13, wherein:

[0071] The charging module 13 includes a charging coil 131;

[0072] A plurality of electromagnet units, wherein a plurality of the electromagnet units are arranged around the charging coil to form an electromagnet array;

[0073] The plurality of electromagnet units 11 are arranged around the charging coil 131 to form an electromagnet array;

[0074] The control unit 12 obtains status information of the charging receiving device 20 , generates configuration information of each of the electromagnet units, activates the electromagnet units and configures them into magnetic structures that match the charging receiving device, and the control unit 12 controls the charging module 13 .

[0075] As mentioned above, in the related art, the existing magnetic wireless charging transmitter device can only be adapted to one charging receiving device, is not compatible and adaptable, and has poor flexibility.

[0076] However, in the embodiment of the present application, based on the magnetic attraction type wireless charging technology, a plurality of said electromagnet units 11 are arranged around the charging coil 131 to form an electromagnet array; the control unit 12 obtains the state information of the charging receiving device 20, generates configuration information of each said electromagnet unit, and activates the configuration of the said electromagnet unit to a magnetic attraction structure matched with the said charging receiving device, which can effectively adapt to various types of charging receiving devices.

[0077] In a specific implementation, the communication mode between the wireless charging transmitting device and the charging receiving device of the embodiment is flexible, and the control unit can obtain the state information of the charging receiving device through a wireless communication protocol or a dial switch or a human-computer interface. The specific setting can be made according to the needs, and the embodiment is not limited specifically.

[0078] Meanwhile, in the embodiment, the state information of the charging receiving device includes at least one of quality information, position information, shape information, model information and magnetic attraction information, and the configuration information of the electromagnet unit includes polarity and magnetic field strength information of the electromagnet unit. According to different charging receiving device state information, the configuration information of each said electromagnet unit is generated. That is, according to at least one of the quality information, position information, shape information, model information and magnetic attraction information of different charging receiving devices, the polarity and magnetic field strength information of each said electromagnet unit are generated. By reasonably configuring the polarity and magnetic force of each electromagnet unit, the said electromagnet unit can be activated and configured to a magnetic attraction structure matched with the said charging receiving device to effectively adapt to various charging receiving devices. The information contained in the charging receiving device state information can also be specifically set according to the needs, and the embodiment is not limited specifically.

[0079] Further reference Figure 2 In a specific implementation, for the control unit 12, two parts, i.e. a master control module 121 and an electromagnet array control module 122, can be set, that is, the master control function and the electromagnet array control function are set as a master control chip and an electromagnet array control chip, or the master control function and the electromagnet array control function are integrated as a master control chip. The specific setting of the present application is not limited.

[0080] In some embodiments, the control unit 12 specifically includes:

[0081] a master control module 121, which obtains the quality information, position information and magnetic attraction information of the charging receiving device;

[0082] An electromagnet array control module 122, which is connected to the main control module 121, receives at least one of the quality information, position information, shape information, model information and magnetic attraction information of the charging receiving device, and activates the electromagnet unit to configure it into a magnetic attraction structure that matches the charging receiving device.

[0083] At the same time, in a specific implementation, the control unit 12 generates configuration information of each of the electromagnet units for the status information of the charging receiving device 20 obtained by the control unit 12, and activates the electromagnet unit to configure the control process of the magnetic attraction structure that matches the charging receiving device. By configuring the magnetic force of the electromagnet unit, the magnetic attraction is activated when the charging receiving device has a positioning deviation, and the dynamic position movement of the charging receiving device 20 on the wireless charging transmitting device 10 is controlled; or the position of the magnetic attraction structure is dynamically adjusted. Specifically:

[0084] Because the charging coil is fixed in position, the charging receiver needs to be aligned with the charging coil. The charging receiver can be moved toward the charging coil by selecting the activated electromagnet and adjusting the strength and direction of the electromagnet's magnetic field. Therefore, in some embodiments, the position information is dynamic; based on the configuration information of the electromagnet unit, the magnetic attraction structure is controlled to remain fixed, and the position information of the charging receiver is dynamically adjusted to move the charging receiver toward the charging coil. Alternatively, in other embodiments, the magnetic attraction structure is dynamically adjusted to move the charging receiver toward the charging coil.

[0085] Therefore, in this embodiment, if the position information is set as dynamic information, the magnetic structure can be controlled to remain fixed based on the configuration information of the electromagnet unit, and the position information of the charging receiver can be dynamically adjusted to move the charging receiver toward the charging coil. That is, when the charging receiver is placed at any position on the charging plate of the wireless charging device, by properly configuring the magnetic force of the electromagnet unit, the magnetic structure can be activated if the charging receiver deviates from its position, achieving dynamic adjustment of the position of the charging receiver to reduce power consumption. At the same time, by dynamically adjusting the magnetic structure, the charging receiver is moved toward the charging coil.

[0086] At the same time, in a specific implementation, for the arrangement of the electromagnet units in the charging coil after activation, the electromagnet units to be activated can be selected according to the status information of the charging receiving device 20, and the shape and position of the magnetic attraction structure can be adjusted. Figure 3-Figure 6 The diagram of the matching of the annular magnetic attraction is shown. At this time, the activated electromagnet units are arranged in an annular manner around the charging coil in the working state. In the actual design, the charging coil 131 can be set as a multi-coil. Figure 4-Figure 6The diagram shows the matching of the annular magnetic attraction mode when the charging coil is a multi-coil. At this time, the activated electromagnet unit 11 is arranged in an annular manner on one side of the working charging coil 131. For example, Figure 4 The middle charging coil is shown to be in working state. At this time, the activated electromagnet units 11 are arranged on both sides of the middle charging coil 131; Figure 5 The left charging coil 131 is shown to be in a working state. At this time, the activated electromagnet unit 11 is arranged on one side of the left charging coil 131. Figure 6 It shows that the right charging coil 131 is in a working state. At this time, the activated electromagnet unit 11 is arranged on one side of the right charging coil 131 . Figure 7 A matching schematic diagram of a discrete magnetic attraction mode is shown. At this time, the activated electromagnet units 11 are discretely arranged around the charging coil 131 in a working state.

[0087] This wireless charging transmitter can dynamically adjust the position of the charging receiver to move it toward the charging coil, or dynamically adjust the position of the magnetic attraction structure. The specific configuration can be selected based on actual needs, offering high flexibility.

[0088] Reference Figure 8 , Figure 8 A flowchart showing the steps of a method for controlling charging by the wireless charging transmitter described above is shown, which may include the following steps:

[0089] S101, arranging a plurality of electromagnet units around the charging coil to form an electromagnet array;

[0090] S102: Acquire status information of the charging receiving device, generate configuration information of each of the electromagnet units, and activate the electromagnet units to configure them into magnetic attraction structures that match the charging receiving device.

[0091] The charging receiving device status information includes at least one of quality information, location information, shape information, model information, and magnetic attraction information;

[0092] Configuration information of each of the electromagnet units is generated according to at least one of the mass information, position information, shape information, model information, and magnetic attraction information.

[0093] In some embodiments, the position information is dynamic information; according to the configuration information of the electromagnet unit, the magnetic attraction structure is controlled to be fixed, and the position information of the charging receiving device is dynamically adjusted to move the charging receiving device toward the charging coil.

[0094] In some embodiments, the magnetic structure can be dynamically adjusted to move the charging receiving device toward the charging coil.

[0095] In summary, the present application addresses the problem that existing magnetic wireless charging transmitters are not compatible and adaptable, and provides a wireless charging transmitter that is compatible with any model of charging transmitter. The wireless charging transmitter arranges a plurality of electromagnet units 11 around the charging coil 131 to form an electromagnet array; the control unit 12 generates configuration information of each of the electromagnet units based on the acquired status information of the charging receiving device 20, and activates the electromagnet units to be configured as a magnetic attraction structure that matches the charging receiving device, that is: based on at least one of the quality information, position information, shape information, model information and magnetic attraction information of different charging receiving devices, the polarity and magnetic field strength information of each of the electromagnet units are generated; by reasonably configuring the polarity, magnetic force, etc. of each electromagnet unit, the electromagnet unit can be activated and configured as a magnetic attraction structure that matches the charging receiving device, so as to effectively be compatible and adaptable to various charging receiving devices.
