The invention is capable of other and different embodiments and its several details are capable of modifications and various other uses and applications, all of which are obvious from the description, without departing from the spirit of the invention. The drawings of the present invention are merely schematic illustrations, and are not intended to be drawn to actual dimensions. The following embodiments will further illustrate the related art content of the present invention in detail, but the disclosure is not intended to limit the scope of the present invention.
For a clearer description of the technical solutions of the embodiments of the present invention, the drawings that are needed in the description of the embodiments will be briefly described, it being apparent that the drawings in the following description are only some embodiments of the present invention, and other drawings may be obtained according to these drawings without excessive effort for a person of ordinary skill in the art. Wherein:
referring to fig. 1, a block diagram of a mouse pad with two sets of charging circuits according to an embodiment of the invention is shown. The mouse pad 10 is suitable for operation with a wireless mouse 7, and the mouse pad 10 comprises a body 100, a first charging circuit 1011, a second charging circuit 1012, a control circuit 103, a power module 107, and a conversion circuit 105.
In one embodiment, the first charging circuit 1011 further includes a first resonant circuit 10111 and a first coil 10113; the second charging circuit 1012 further includes a second resonant circuit 10121, a second coil 10123, and so on.
The body 100 may be a one-piece or multi-piece structure, such as a single base material, or a reflective material and an anti-slip material, but is not limited thereto. The body 100 may be configured to house a second charging circuit 1012, a first charging circuit 1011, and the like.
Generally, the first charging circuit 1011 and the second charging circuit 1012 each have a transmitting end, a receiving end, and corresponding coils, inductors, and capacitors. However, those skilled in the art should understand that the transmitting end, the receiving end and the electronic components thereof are not described herein.
In one embodiment, the first resonant circuit 10111 is electrically connected to the first coil 10113, and the second resonant circuit 10121 is electrically connected to the first coil 10123. The first coil 10113 and the second coil 10123 are both thin coils.
The first resonant circuit 10111 includes, for example, a first inductor, a first capacitor, and a first resistor. The first inductance, the first capacitance, and the first resistance of the first resonant circuit 10111 form a first resonant parameter. The inductance, capacitance, and resistance of the first resonant circuit 10111 in this embodiment are connected in series in the circuit schematic. However, in other embodiments, the first resonant circuit 10111 may be composed of different electronic components, which is not limited to the above embodiments.
Similarly, the second resonant circuit 10121 includes at least a second inductor, a second capacitor and a second resistor. The second inductance, the second capacitance and the second resistance of the second resonant circuit 10121 form a second resonant parameter. The inductance, capacitance, and resistance of the second resonant circuit 10121 are connected in series in the circuit schematic. However, in other embodiments, the first resonant circuit 10121 may be composed of different electronic components, which is not limited to the above embodiments.
The control circuit 103 is disposed in the body 100 and electrically connected to the first charging circuit 1011, the second charging circuit 1012 and the conversion circuit 105. Since the control circuit 103 may have various switches, the supply current of the power module 107 to the first charging circuit 1011 and the second charging circuit 1012 may be dynamically adjusted.
The conversion circuits 105 are respectively electrically connected with the control circuit 103, and the power supply module 107 is electrically connected with the conversion circuits 105; the conversion circuit 105 may provide operating power required by the first charging circuit 1011 and the second charging circuit 1012.
After the power module 107 is started, the first charging circuit 1011, the control circuit 103 and the power module 107 have an electrical connection relationship, and the second charging circuit 1012, the control circuit 103 and the power module 107 also have an electrical connection relationship, so that the first charging circuit 1011 and the second charging circuit 1012 can respectively wirelessly output electromagnetic energy to the wireless mouse 7.
Thus, if electromagnetic energy is actively transmitted, it is generally considered as an active wireless charging circuit to actively transmit wireless power due to the electrical coupling between the first charging circuit 1011 and the power module 107 or between the second charging circuit 1012 and the power module 107.
However, when the electrical connection between the first charging circuit 1011 and the power module 107 or between the second charging circuit 1012 and the power module 107 is interrupted, the first charging circuit 1011 and the second charging circuit 1012 need to receive wireless power from the active wireless charging circuit to transmit wireless power to the wireless mouse 7, and the first charging circuit 1011 and the second charging circuit 1012 are regarded as passive wireless charging circuits.
In one embodiment, the first charging circuit 1011 is configured to be electrically coupled to the second charging circuit 1012. After the second charging circuit 1012 receives the wireless power of the first charging circuit 1011, the second charging circuit 1012 may transmit the wireless power to a wireless mouse 7.
In detail, the second charging circuit 1012 is similar to a relay station for power transmission, and can transmit wireless power to the wireless mouse 7 with matching resonance parameters. The second charging circuit 1012 can receive wireless power from the first charging circuit 1011 through the first charging circuit 1011, and can also transmit wireless power to the wireless mouse 7.
Since the first charging circuit 1011 and the second charging circuit 1012 each include a transmitting terminal and a receiving terminal. In one embodiment, the magnetic field generated by the transmitting end coil of the first charging circuit 1011 passes through the receiving end coil of the first charging circuit 1011, and the receiving end coil of the first charging circuit 1011 generates an electric field. Once a load is connected to the receiving end coil of the first charging circuit 1011, the first charging circuit 1011 generates a load current. However, in another embodiment, a load may be connected to the receiving end coil of the second charging circuit 1012 to generate a load current. The invention is not limited thereto.
In one embodiment, when the control circuit 103 receives the load current flowing through the first charging circuit 1011 and the load current flowing through the second charging circuit 1012, the difference between the load current flowing through the first charging circuit 1011 and the load current flowing through the second charging circuit 1012 is determined to be greater than a first threshold, which means that the wireless mouse 7 receives more electromagnetic energy from the first charging circuit 1011 and the wireless mouse 7 receives less electromagnetic energy from the second charging circuit 1012, the control circuit 103 can make the second charging circuit and the power module non-conductive. At this time, the first charging circuit 1011 may be regarded as an active wireless charging circuit, and the second charging circuit 1012 may be regarded as a passive wireless charging circuit, so as to dynamically adjust the supply current of the power module 107 to the first charging circuit 1011 and the second charging circuit 1012.
In one embodiment, when the control circuit 103 receives the load current flowing through the first charging circuit 1011 and the load current flowing through the second charging circuit 1012, and the difference between the load current flowing through the first charging circuit 1011 and the load current flowing through the second charging circuit 1012 is determined to be smaller than the first threshold, it means that the wireless mouse 7 receives less electromagnetic energy from the first charging circuit 1011, and the wireless mouse 7 receives more electromagnetic energy from the second charging circuit 1012, so that the control circuit 103 can make the first charging circuit and the power module non-conductive. At this time, the first charging circuit 1011 may be regarded as a passive wireless charging circuit, and the second charging circuit 1012 may be regarded as an active wireless charging circuit, so as to dynamically adjust the supply current of the power module 107 to the first charging circuit 1011 and the second charging circuit 1012.
In one embodiment, the control circuit 103 further includes an auxiliary circuit (not shown) for detecting the load current flowing through the first charging circuit 1011 or the second charging circuit 1012.

The first charging circuit 1011, the second charging circuit 1012, the third charging circuit 1013, and the fourth charging circuit 1014 wirelessly output electromagnetic energy to the wireless mouse 7, respectively.
When the control circuit 103 receives a third load current, a fourth load current, a fifth load current and a sixth load current flowing through the first charging circuit 1011, the second charging circuit 1012, the third charging circuit 1013 and the fourth charging circuit 1014, respectively, the control circuit 103 enables one of the first charging circuit 1011, the second charging circuit 1012, the third charging circuit 1013 and the fourth charging circuit 1014 to be conducted with the power module 107, and enables the other three of the first charging circuit 1011, the second charging circuit 1012, the third charging circuit 1013 and the fourth charging circuit 1014 to be non-conducted with the power module 107.
In an embodiment, the control circuit 103 determines, according to the magnitude relation among the third load current, the fourth load current, the fifth load current and the sixth load current, which belongs to the relative maximum load current, so that the member of the combination of the first charging circuit 1011, the second charging circuit 1012, the third charging circuit 1013 and the fourth charging circuit 1014 corresponding to the relative maximum load current is conducted with the power module 107, and the rest of the combination of the first charging circuit 1011, the second charging circuit 1012, the third charging circuit 1013 and the fourth charging circuit 1014 (the member not having the relative maximum load current) is not conducted with the power module 107.
As such, one of the combinations of the first charging circuit 1011, the second charging circuit 1012, the third charging circuit 1013, and the fourth charging circuit 1014 may be regarded as an active wireless charging circuit; and, one of the combinations of the first charging circuit 1011, the second charging circuit 1012, the third charging circuit 1013, and the fourth charging circuit 1014 is regarded as a passive wireless charging circuit, so as to dynamically adjust the power supply current of the power module 107 to the combination of the first charging circuit 1011, the second charging circuit 1012, the third charging circuit 1013, and the fourth charging circuit 1014.

The power module 17 is electrically connected to the first wireless charging and transmitting circuit 3011 to provide an operating voltage of the first wireless charging and transmitting circuit 3011.
The conversion circuit 105 is electrically connected to the power module 107 and the control circuit 103, wherein the control circuit 103 may make the second wireless charging circuit 3012 conductive or nonconductive to the conversion circuit 105.
The power module 107, the control circuit 103, the first wireless charging transmitting circuit 3011 and the second wireless charging circuit 3012 are all configured in the main body 300.
Specifically, the first wireless charging transmitting circuit 3011 is electrically connected to the control circuit 103 and the power module 107, the second wireless charging circuit 3012 is electrically connected to the control circuit 103, and the first wireless charging transmitting circuit 3011 and the second wireless charging circuit 3012 are arranged in a staggered manner.

However, in other embodiments, the mouse pad may include a plurality of sets of first wireless charging transmitting circuits and a plurality of sets of second wireless charging circuits. On a plane, the first wireless charging transmitting circuit and the second wireless charging circuit can be arranged in a relatively staggered manner so as to achieve a better electric energy coupling effect.
After the power module 107 starts to supply power, the control circuit 103 may make the second wireless charging circuit 3012 and the conversion circuit 105 non-conductive. The second wireless charging circuit 3012 receives a first electromagnetic energy provided by the first wireless charging transmitting circuit 3011 wirelessly and converts the first electromagnetic energy into an operating electrical energy.
