The invention is capable of other and different embodiments and its several details are capable of modification and various other changes, which can be made in various details within the specification and without departing from the spirit and scope of the invention. The drawings of the present invention are for illustrative purposes only and are not intended to be drawn to scale. The following embodiments will further explain the related art of the present invention in detail, but the disclosure is not intended to limit the scope of the present invention.
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings based on these drawings without undue effort. Wherein:
referring to fig. 1, a block diagram of a mouse pad with two charging circuits according to an embodiment of the invention is shown. A mouse pad 10 is suitable for being operated with a wireless mouse 7, and the mouse pad 10 includes a main 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 and a second coil 10123.
The body 100 may be a one-piece or multi-piece structure, such as a single base material, or a reflective material and a non-slip material, without limitation. The body 100 can accommodate a second charging circuit 1012, a first charging circuit 1011, and other components.
Generally, the first charging circuit 1011 and the second charging circuit 1012 have a transmitting terminal, a receiving terminal, and corresponding coils, inductors, and capacitors. However, those skilled in the art should understand the transmitting end, the receiving end and their electronic components required for wireless charging, and will not be described herein again.
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, for example, includes at least a first inductor, a first capacitor, and a first resistor. The first inductor, the first capacitor and the first resistor of the first resonant circuit 10111 form a first resonant parameter. In the present embodiment, the inductor, the capacitor, and the resistor of the first resonant circuit 10111 are connected in series in the circuit diagram. However, in other embodiments, the first resonant circuit 10111 may be composed of different electronic components, and the invention is not limited thereto.
Similarly, the second resonant circuit 10121 includes at least a second inductor, a second capacitor, and a second resistor. The second inductor, the second capacitor and the second resistor of the second resonant circuit 10121 form a second resonant parameter. The inductor, capacitor and resistor of the second resonant circuit 10121 are connected in series in the circuit diagram. However, in other embodiments, the first resonant circuit 10121 may be composed of different electronic components, and the invention is not limited thereto.
The control circuit 103 is disposed in the main body 100 and electrically connected to the first charging circuit 1011, the second charging circuit 1012 and the converting circuit 105. Since the control circuit 103 may have various switches, the power supply current of the power module 107 to the first charging circuit 1011 and the second charging circuit 1012 can be dynamically adjusted.
The conversion circuit 105 is electrically connected with the control circuit 103, and the power module 107 is electrically connected with the conversion circuit 105; the conversion circuit 105 can provide the operation power required by the first charging circuit 1011 and the second charging circuit 1012.
After the power module 107 is activated, since the first charging circuit 1011, the control circuit 103 and the power module 107 are electrically connected, and the second charging circuit 1012, the control circuit 103 and the power module 107 are also electrically connected, the first charging circuit 1011 and the second charging circuit 1012 can respectively wirelessly output electromagnetic energy to the wireless mouse 7.
Therefore, if it is determined whether to actively transmit electromagnetic energy, since the first charging circuit 1011 and the power module 107 or the second charging circuit 1012 and the power module 107 are electrically coupled, it can be generally regarded as an active wireless charging circuit to actively transmit wireless power.
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 the wireless power from the active wireless charging circuit to transmit the 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 couple with the second charging circuit 1012. After the second charging circuit 1012 receives the wireless power from 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, like a relay station for power transmission, can transmit wireless power to the wireless mouse 7 having 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 also transmit the 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 coil of the first charging circuit 1011 will pass through the receiving coil of the first charging circuit 1011, and the receiving coil of the first charging circuit 1011 will generate an electric field. Once a load is applied to the receiving 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 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, 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 greater than a first threshold, it 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, so that the second charging circuit and the power module are not conducted through the control circuit 103. At this time, the first charging circuit 1011 can be regarded as an active wireless charging circuit, and the second charging circuit 1012 can be regarded as a passive wireless charging circuit, so as to dynamically adjust the power supply current of the power module 107 to the first charging circuit 1011 and the second charging circuit 1012.
In an 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 electromagnetic energy received by the wireless mouse 7 from the first charging circuit 1011 is less, and the electromagnetic energy received by the wireless mouse 7 from the second charging circuit 1012 is more, so that the first charging circuit and the power module are not conducted through the control circuit 103. At this time, the first charging circuit 1011 can be regarded as a passive wireless charging circuit, and the second charging circuit 1012 can be regarded as an active wireless charging circuit, so as to dynamically adjust the power 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.

When the control circuit 103 receives a third load current, a fourth load current, a fifth load current and a sixth load current respectively flowing through the first charging circuit 1011, the second charging circuit 1012, the third charging circuit 1013 and the fourth charging circuit 1014, the control circuit 103 makes one of the first charging circuit 1011, the second charging circuit 1012, the third charging circuit 1013 and the fourth charging circuit 1014 and the power module 107 be conducted, and makes 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 and the power module 107 be not conducted.
In one embodiment, the control circuit 103 determines, according to the magnitude relationship among the third load current, the fourth load current, the fifth load current and the sixth load current, one of the third load current, the fourth load current, the fifth load current and the sixth load current, which is the relatively 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 relatively maximum load current is conducted with the power module 107, and the remaining three (members without the relatively maximum load current) 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 are not conducted with the power module 107.
As such, one 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 can be regarded as an active wireless charging circuit; three 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 are regarded as passive wireless charging circuits, 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.

In one embodiment, when the auxiliary circuit 109 detects that the amount of the load current flowing through one of the second wireless charging circuits 3012 and 3014 is greater than a sixth threshold value compared to the amount of the load current flowing through the other of the second wireless charging circuits 3012 and 3014, the auxiliary circuit 109 sends a notification signal to the control circuit 103, and the control circuit 103 turns on the switching circuit 105 and one of the second wireless charging circuits 3012 and 3014 according to the notification signal.
In one embodiment, the wireless mouse 7 is separated from the second wireless charging circuit 3012 and 3014 by a unit length of D1 and D2, respectively. In one example, when D1 is smaller than D2, the second wireless charging circuit 3012 transmits more wireless power to the wireless mouse 7 because it is closer to the wireless mouse 7, and the second wireless charging circuit 3014 transmits less wireless power to the wireless mouse 7. The control circuit 103 causes the second wireless charging circuit 3014 to turn off depending on the amount of wireless energy transmitted by the coils of the second wireless charging circuits 3012 and 3014. In another example, when D2 is smaller than D1, the second wireless charging circuit 3014 transmits more wireless power to the wireless mouse 7 because it is closer to the wireless mouse 7, and the second wireless charging circuit 3012 transmits less wireless power to the wireless mouse 7. The control circuit 103 causes the second wireless charging circuit 3012 to turn off depending on the amount of wireless energy transmitted by the coils of the second wireless charging circuits 3012 and 3014.
