However, while the principles of the application have been described in language specific to above, it is not intended to be limited to the specific form set forth herein, and it will be recognized by those of ordinary skill in the art that various of the steps and operations described below may be implemented in hardware.

Wireless charging technology does not need the cable to accomplish the transmission of power, therefore, wireless charging technology is receiving more and more people's favor.

In a conventional wireless charging technology, an adapter is generally connected to a wireless charging device (e.g., a wireless charging base), and output power of the adapter is wirelessly transmitted (e.g., electromagnetic waves) to a device to be charged through the wireless charging device, so as to wirelessly charge the device to be charged.

According to different wireless charging principles, wireless charging methods are mainly classified into three methods, namely magnetic coupling (or electromagnetic induction), magnetic resonance and radio wave. Most electronic devices supporting wireless charging in the market currently adopt a magnetic coupling mode, but the transmission distance of the wireless charging mode is short. The wireless charging mode provided in the embodiment of the present application may include a radio wave mode, and the wireless charging device may convert the environmental electromagnetic wave into a current and transmit the current through a circuit.

Fig. 1 is a schematic structural diagram of a wireless charging system provided in an embodiment of the present application. The wireless charging system in fig. 1 includes a wireless charging apparatus 10 and a device to be charged 20.

The wireless charging device 10 includes an external interface 11, a base 12, and a wireless charging module 13 disposed on the base 12, wherein the external interface 11 is used for connecting a power supply to supply power to the wireless charging device 10, and in some embodiments, the external interface 11 may also be used for transmitting data provided by an external device. The external interface 11 of the wireless charging apparatus 10 may include, for example, at least one of a serial port, a Universal Serial Bus (USB), and the like. The USB interface may be, for example, a USB 2.0 interface, a USB 3.0 interface, or a TYPE-C interface.

The wireless charging module 13 can receive the detection signal sent by the device to be charged 20 and send an energy signal to the device to be charged 20, so as to perform wireless charging.

As used in embodiments of the present invention, a device to be charged may refer to a terminal, which may include, but is not limited to, a device configured to receive/transmit communication signals via a wireline connection (e.g., via a Public Switched Telephone Network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection, and/or another data connection/network) and/or via a wireless interface (e.g., for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a digital video broadcasting-handheld (DVB-H) network, a satellite network, an amplitude modulation-frequency modulation (AM-FM) broadcast transmitter, and/or another communication terminal). Terminals that are arranged to communicate over a wireless interface may be referred to as "wireless communication terminals", "wireless terminals", and/or "mobile terminals". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; personal Communication System (PCS) terminals that may combine cellular radiotelephones with data processing, facsimile, and data communication capabilities; personal Digital Assistants (PDAs) that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. In addition, the device to be charged or the terminal used in the embodiment of the present invention may further include a power bank (power bank), and the power bank may be charged by the power bank, so that energy may be stored to provide energy for other electronic devices.

With reference to fig. 2, the wireless charging device 10 includes an external interface 11, a base 12, a control module 14, and a wireless charging module 13 disposed on the base 12 and configured to provide a structural schematic view of the wireless charging device according to the embodiment of the present disclosure. In this embodiment, the wireless charging module 13 includes a plurality of sub-modules 131, and the wireless charging module 13 is configured to receive a detection signal sent by the device to be charged 20, determine a target sub-module from the plurality of sub-modules 131 according to the detection signal, and wirelessly charge the device to be charged 20 through the target sub-module.

In an embodiment, the sub-module 131 includes a signal receiving module and an energy sending module, the signal receiving module is configured to receive a detection signal sent by the device to be charged 20, and the energy sending module is configured to send an energy signal to the device to be charged 20, so as to wirelessly charge the device to be charged 20.

In an embodiment, the control module 14 is configured to select a target sub-module according to the strength of the signals received by the plurality of sub-modules 131 after the plurality of sub-modules 131 receive the detection signal sent by the to-be-charged device 20. For example, the wireless charging module 13 includes 5 sub-modules 131, and after the device 20 to be charged sends the detection signal, the 5 sub-modules 131 can all receive the detection signal, but due to the distance or the shielding, the signal strengths of the detection signals received by the 5 sub-modules 131 are different, and at this time, the sub-module with the strongest received signal strength can be selected as the target sub-module.

In practical applications, if the sub-modules 131 of the wireless charging module 13 are disposed on a plane, the radiation range may have a dead angle, and the radiation range is small. Therefore, in an embodiment, the base 12 may have an arc surface on which the plurality of sub-modules 131 of the wireless charging module 13 are disposed, so as to increase the radiation range of the wireless charging module 13 for transmitting and receiving signals, and the arc surface may be a convex surface or a concave surface.

That is, the plurality of sub-modules 131 of the wireless charging module 13 are disposed on the spherical surface, and the base 12 can be mounted on the wall 30 through the external interface 11. Since the base 12 is disposed on the wall, in one embodiment, only the wireless charging module 13 is disposed on the lower half portion of the spherical base, that is, the sub-modules 131 of the wireless charging module 13 are disposed on the lower half portion of the spherical surface.

In an embodiment, in order to further reduce the size of the base 12 and reduce the occupied space, the base 12 may also be a hemisphere, as shown in fig. 4, the hemisphere includes a straight surface 121 and a spherical surface 122, the wireless charging module 13 is disposed on the spherical surface 122, that is, the plurality of sub-modules 131 of the wireless charging module 13 are disposed on the spherical surface 122.

In this embodiment of the application, because a plurality of sub-modules 131 that set up on sphere 122 are towards different angles respectively, can receive the detection signal that the terminal that waits to charge in different position sent, it is specific, when the terminal needs to charge, the terminal can be to charging device transmission detection signal, and charging device can acquire this detection signal through wireless charging module 13 to it specifically is which sub-module 131 received the signal to fix a position to the realization to the terminal. When a plurality of sub-modules 131 all receive the detection signal sent by the same terminal, the target sub-module may be selected according to the signal strength, for example, the sub-module with the strongest signal strength that receives the detection signal may be selected as the target sub-module, and finally, the energy signal is sent to the terminal to be charged through the target sub-module, so as to wirelessly charge the device to be charged.

In an embodiment, the wireless charging apparatus provided in this embodiment of the present application may also wirelessly charge a plurality of terminals at the same time, as shown in fig. 5, when the wireless charging module 10 receives the detection signals sent by a plurality of devices to be charged 20, respectively determine, from the plurality of sub-modules 131, target sub-modules corresponding to the plurality of devices to be charged 20 according to the plurality of detection signals, and wirelessly charge the plurality of devices to be charged through the target sub-modules.

When the plurality of terminals are charged wirelessly through the wireless charging device, charging power can be distributed according to the residual capacity of the plurality of terminals to be charged. For example, when two terminals are wirelessly charged by using the wireless charging device, the remaining capacity of the first terminal is 25%, the remaining capacity of the second terminal is 50%, and the maximum charging power of the wireless charging device is 15W, the charging power of the first terminal may be set to 10W, and the charging power of the second terminal may be set to 5W. It should be noted that the power distribution process may include current distribution and voltage distribution, and taking the charging power as 10W as an example, the voltage and the current may be 5V and 2A, respectively, or the voltage and the current may be 10V and 1A, respectively.

By last can know, the wireless charging device that this application embodiment provided includes base and the wireless module of charging, and the wireless module setting of charging is on the base, and the wireless module of charging includes a plurality of sub-modules, and the wireless module of charging is used for receiving the detection signal that waits to charge equipment and send to according to the detection signal confirm the target sub-module in the middle of a plurality of sub-modules, charge equipment wireless through the target sub-module.
