The charging board can wirelessly charge the wireless charging mouse, and the wireless charging function of the charging board can be selectively turned on or off depending on the actual usage. For example, when the charging pad is connected to the wireless receiver, the charging pad can activate the wireless charging function accordingly. Or when the charging pad is not connected with the wireless receiver, the charging pad can turn off the wireless charging function accordingly.

Furthermore, when the charging board is connected to the wireless receiver, the charging board can further determine whether the wireless charging mouse is placed on it. For example, when the wireless charging mouse is placed on the charging pad, the charging pad can enter the working mode to provide normal charging function for the wireless charging mouse. On the other hand, when the wireless charging mouse is not placed on the charging board, the charging board can enter the charging function of the power saving mode, so as to avoid the charging board that may cause charging when the charging board wirelessly charges any metal object that is not a wireless charging mouse for a long time. Unnecessary functions of the board are impaired.

Please refer to FIG. 1 , which is a schematic diagram of a wireless input device provided by an embodiment of the present invention. The wireless input device of this embodiment may include a charging pad 1 , a wireless receiver 2 and a wireless charging mouse 3 . Wherein the wireless receiver 2 can be connected to the charging board 1 , and the wireless receiver 2 can output related signals such as start signal, working signal or operation signal to the charging board 1 . The charging board 1 can receive the signal output by the wireless receiver 2 and can provide the wireless charging function for the wireless charging mouse 3 . In addition, the charging board 1 also has a transmission line 12, such as a USB transmission line, which can be connected to a computer device (not shown in the figure), so that the charging board 1 can obtain power from the computer device. Furthermore, the charging board 1 can also transmit the operation signal output from the wireless charging mouse 3 to the wireless receiver 2 to the computer device. The wireless charging mouse 3 can, for example, wirelessly output charging signals or operating signals to the wireless receiver 2 . It is worth noting that when the wireless receiver 2 is not connected to the charging pad 1 , the wireless receiver 2 and the wireless charging mouse 3 can still be used together. For example, when the user does not carry the charging board 1 when going out, but only carries the wireless receiver 2 and the wireless charging mouse 3, the user can still connect the wireless receiver 2 directly to the host computer, and the wireless charging can be performed normally. Mouse 3 is used for manipulation.

In one embodiment, the connection manner between the wireless receiver 2 and the charging board 1 can be illustrated as follows. The charging board 1 is provided with a port 11 and a first contact interface 13 . The wireless receiver 2 is provided with a socket portion 21 and a second contact interface 23 . The wireless receiver 2 can be plugged into the port 11 of the charging board 1 through the socket 21 , so that the wireless receiver 2 can be connected with the charging board 1 . In addition, it should be noted that when the wireless receiver 2 and the charging board 1 are connected in the above manner, the first contact interface 13 of the charging board 1 and the second contact interface 23 of the wireless receiver 2 are in electrical contact with each other. However, the arrangement positions of the first contact interface 13 and the second contact interface 23 in FIG. 1 are only for illustration, and are not intended to limit the present invention. The positions of the first contact interface 13 and the second contact interface 23 can be any position where the first contact interface 13 and the second contact interface 23 can electrically contact each other when the wireless receiver 2 and the charging board 1 are connected to each other. In addition, the plug portion 21 and the port 11 are, for example, USB connectors conforming to the USB transmission standard.

Furthermore, the charging board 1 can know whether the wireless receiver 2 is connected to the charging board 1 by judging whether the start signal output by the wireless receiver 2 is received. For example, when the charging board 1 receives the start signal, it means that the wireless receiver 2 has been connected to the charging board 1, and at this time the charging board 1 can start the wireless charging function, and then the wireless charging mouse 3 placed on the charging board 1 Charge.

In one embodiment, when the wireless receiver 2 is connected to the charging pad 1 and the wireless charging mouse 3 is not placed on the charging pad 1 , the charging pad 1 activates the wireless charging function in a power saving mode. The power-saving mode mentioned here means that the charging board 1 wirelessly outputs electromagnetic energy in an intermittent manner, for example, the charging board 1 outputs electromagnetic energy in an alternate manner for a period of time (such as one second) and stops outputting electromagnetic energy for a period of time (such as one second). The invention is not limited thereto. On the other hand, when the wireless receiver 2 is connected to the charging pad 1 and the wireless charging mouse 3 is also placed on the charging pad 1 , the wireless charging function of the charging pad 1 is activated in the working mode. The working mode mentioned here means that the charging board 1 wirelessly outputs electromagnetic energy to charge the wireless charging mouse 3 in an uninterrupted and continuous manner.

In an embodiment, the charging board 1 can also determine whether the wireless charging mouse 3 is placed on it by whether it receives the working signal output by the wireless receiver 2 or not. For example, when the wireless charging mouse 3 is placed on the charging pad 1 for charging, the wireless charging mouse 3 can relatively output a charging signal to the wireless receiver 2 according to receiving the electromagnetic energy provided by the charging pad 1 . And when the wireless receiver 2 receives the charging signal, it can further output a working signal to the charging board 1 . That is to say, when the charging board 1 receives the working signal, it can be known that the wireless charging mouse 3 has been placed on the charging board 1, and when the charging board 1 does not receive the working signal, it can be known that the wireless charging mouse 3 is not Place it on the charging pad 1.

Please refer to FIG. 2 . FIG. 2 is a functional block diagram of a wireless input device provided by an embodiment of the present invention. Please refer to FIG. 1 while describing FIG. 2 .

The power circuit 33 is electrically connected to the wireless power receiving circuit 31 , the mouse control circuit 35 and the wireless communication circuit 37 . The mouse control circuit 35 is electrically connected to the wireless communication circuit 37 and the wireless power receiving circuit 31 .

Specifically, the charging control circuit 15 in the charging board 1 can receive the activation signal and the working signal output by the wireless receiver 2 through the first contact interface 13, and receive the operation signal output by the wireless receiver 2 through the port 11, and this port 11 is further electrically connected to some transmission lines 12 . For example, when the wireless receiver 2 is connected to the charging board 1 and the wireless charging mouse 3 is not placed on the charging board 1, the charging control circuit 15 receives the start signal through the first contact interface 13, and the charging control circuit 15 starts the wireless power transmission module 17 Operation, for example, the charging control circuit 15 controls the wireless power transmission module 17 to wirelessly output electromagnetic energy in the power saving mode, that is, the wireless power transmission module 17 is intermittently wirelessly outputting electromagnetic energy. In addition, the charging control circuit 15 can also obtain the power supply provided by the computer device through the transmission line 12 from the port 11 , and the wireless receiver 2 connected to the charging board 1 can also obtain the power supply provided by the computer device through the transmission line 12 from the port 11 .

On the other hand, when the wireless receiver 2 is connected to the charging board 1 and the wireless charging mouse 3 has been placed on the charging board 1, the charging control circuit 15 can also receive the start signal through the first contact interface 13 at this time. to work signal. The charging control circuit 15 relatively controls the wireless power transmitting module 17 to wirelessly output electromagnetic energy in the working mode according to the received working signal, that is, the wireless power transmitting module 17 is continuously wirelessly outputting electromagnetic energy to charge the wireless charging mouse 3 without interruption, And until the charging control circuit 15 does not receive the working signal, that is, when the wireless charging mouse 3 is not placed on the charging pad 1 , the charging pad 1 switches to the power saving mode again. It can be seen that when the wireless receiver 2 is connected to the charging board 1 , the charging control circuit 15 can relatively switch the wireless power transmitting module 17 to operate in the power saving mode or the working mode according to whether the charging board 1 has placed the wireless charging mouse 3 . In addition, when the wireless receiver 2 is connected to the charging board 1 , the charging board 1 can also receive the operation signal output by the wireless receiver 2 from the port 11 , and the charging board 1 can also transmit the operation signal to the computer device through the transmission line 12 .

Furthermore, when the wireless receiver 2 is not connected to the charging board 1, and the charging control circuit 15 of the charging board 1 cannot receive the activation signal from the first contact interface 13, the charging board 1 immediately turns off the wireless charging function of the wireless charging mouse 3 . In detail, at this time, the charging control circuit 15 controls the wireless power transmission module 17 to stop outputting electromagnetic energy.

In one embodiment, when the wireless charging mouse 3 is placed on the charging pad 1 , the wireless power receiving circuit 31 of the wireless charging mouse 3 can wirelessly receive the electromagnetic energy output by the charging pad 1 through the wireless power transmitting module 17 . The power supply circuit 33 in the wireless charging mouse 3 can perform relevant power supply processing on the electromagnetic energy received by the wireless power receiving circuit 31 and then output direct current to the internal circuit of the wireless charging mouse 1 for use. For example, the DC power output by the power supply circuit 33 can be supplied to the wireless communication circuit 37 and the mouse control circuit 35 for use. The power circuit 33 includes, but is not limited to, a power conversion circuit, a charging circuit, and a rechargeable battery, for example. The actual implementations of the wireless power transmitting module 17 , the wireless power receiving circuit 31 and the power supply circuit 33 are known to those skilled in the art and will not be described in detail here. The mouse control circuit 35 includes, but is not limited to, a microprocessor, a displacement detection circuit, and a key circuit. The main function of the mouse control circuit 35 is to generate an operation signal to the wireless communication circuit 37 according to the movement or key operation of the wireless charging mouse 3 . The operation signal can be, for example, a cursor movement signal or a key signal. And the operation signal is output to the wireless receiver 2 through the wireless communication circuit 37 .

It should be noted that the mouse control circuit 35 can also determine whether the wireless power receiving circuit 31 has received the electromagnetic energy output by the charging board 1 , and accordingly decide whether to output a charging signal to the wireless receiver 2 . For example, when the wireless power receiving circuit 31 receives electromagnetic energy, the mouse control circuit 35 outputs a charging signal to the wireless receiver 2 through the wireless communication circuit 37, and when the wireless power receiving circuit 31 does not receive electromagnetic energy, the mouse control circuit 35 Then the wireless communication circuit 37 will not output the charging signal to the wireless receiver 2 . That is to say, when the charging board 1 outputs electromagnetic energy in the power-saving mode, if the wireless charging mouse 3 can still receive the electromagnetic energy output by the electromagnetic board 1 when placed on the charging board 1, and the wireless charging mouse 3 can output a charging signal To the wireless receiver 2, so that the wireless receiver 2 can output the working signal to the charging board 1, so that the charging board 1 can switch from the power saving mode to the working mode, and the wireless charging mouse 3 can stably obtain the output of the charging board 1. electromagnetic energy.

And when the receiving control circuit 25 receives a charging signal through the wireless communication circuit 27 , the receiving control circuit 25 can relatively output a working signal to the first contact interface 13 of the charging board 1 through the second contact interface 23 according to the charging signal. In addition, the receiving control circuit 25 can also output an activation signal to the first contact interface 13 of the charging board 1 through the second contact interface 23 . The timing for receiving the start signal output by the control circuit 25 may be, for example, when the plug-in part 21 is plugged into the port 11 to obtain power supply and start to output. Or the receiving control circuit 25 can also output a start signal when the receiving control circuit 25 detects that the second contact interface 23 is in contact with the first contact interface 13 after the socket part 21 is plugged into the port 11 to obtain power supply. There is no limit to this. In addition, the wireless transmission technology used by the wireless communication circuit 27 and the wireless communication circuit 37 may be radio frequency or bluetooth, for example.
