The wireless charging mouse provided by the embodiment of the invention can dynamically adjust the charging power and the operating power of the wireless charging mouse so that the wireless charging mouse can normally maintain operation when moving or not moving. The operating electrical energy referred to herein refers to the electrical energy used when the wireless charging mouse is operated, and the charging electrical energy refers to the electrical energy used to provide the rechargeable battery. Specifically, the wireless charging mouse consumes more power than the unmoved power, so the wireless charging mouse of the present invention can selectively increase the operating power required for operation and reduce the charging power when moving. In another aspect, the wireless charging mouse of the present invention can also selectively increase charging power and reduce operating power required for operation when not moving. A more detailed explanation will be given below.

Please refer to FIG. 1. FIG. 1 is a block diagram of a wireless charging mouse according to an embodiment of the present invention. The wireless charging mouse 1 includes a wireless power receiving circuit 105, a displacement detecting circuit 110, a wireless transmitting circuit 115, a charging circuit 120, a control circuit 125, a power switching circuit 130, and a rechargeable battery 135. For convenience of the following description, the operation circuit 140 includes, for example, a displacement detecting circuit 110, a wireless transmitting circuit 115, and a control circuit 125. The control circuit 125 is electrically connected to the wireless power receiving circuit 105, the displacement detecting circuit 110, the wireless transmitting circuit 115, and the power switching circuit 130, respectively. In addition, the operation circuit 140 can receive the operating power provided by the power switching circuit 130 or receive the battery power provided by the rechargeable battery 135, and can be used as the power required for the operation of the internal circuit of the operating circuit 140. In addition, the operation circuit 140 may further include different types of related input circuits, such as a button circuit, a roller circuit or a touch circuit, to provide various operation input requirements of the wireless charging mouse 1, and the implementation of the operation circuit 140 is not limited herein.

The wireless power receiving circuit 105 can wirelessly receive the electromagnetic energy supplied from the charging pad and use it as the charging power or the operating power of the wireless charging mouse 1. In detail, the wireless power receiving circuit 105 can be electromagnetically coupled with the charging board. For example, when the resonant frequency of the magnetic coil in the wireless power receiving circuit 105 is the same as the resonant frequency of the magnetic coil of the wireless transmitting circuit of the charging pad, the wireless charging is slippery. The mouse 1 can wirelessly receive the electromagnetic energy transmitted by the charging pad. In an embodiment, the wireless power receiving circuit 105 may further include an electromagnetic conversion circuit for converting electromagnetic energy into electrical energy.

The wireless power receiving circuit 105 transmits the power to the power switching circuit 130. The power switching circuit 130 can dynamically allocate power to the operating power and the charging power according to the power switching signal. In detail, the power switching circuit 130 can adjust the ratio of the electrical energy of the operating power and the charging electrical energy. For example, the power switching circuit 130 can control a part or all of the output power of the wireless power receiving circuit 105 to be allocated to the operating power for the operation of the operating circuit 140; or the power switching circuit 130 can also output the power to the wireless power receiving circuit 105. Part or all of the charging power is distributed to the charging circuit 120, and the charging circuit 120 transmits the charging power. To the rechargeable battery 135 for storing power, the rechargeable battery 135 can transfer the stored battery power to the operating circuit 140.

The displacement detecting circuit 110 is configured to detect the movement of the wireless charging mouse 1. The displacement detecting circuit 110 is implemented by, for example, optical detection to determine the amount of movement and the moving direction of the wireless charging mouse 1. However, the present invention does not The detection method is limited. The light source unit (not shown) of the displacement detecting circuit 110 can illuminate a plane for laser or infrared, and the receiving unit (not shown) of the displacement detecting circuit 110 can receive the reflection of the plane. The laser or infrared rays calculate the amount of movement and the moving direction of the wireless charging mouse 1 by the difference value between the incident light and the reflected light.

The control circuit 125 generates a displacement detection signal according to the detection result of the displacement detecting circuit 110. The control circuit 125 can transmit the displacement detection signal to the wireless transmission circuit 115, and output the displacement detection signal to the electronic device (not shown) through the wireless communication function of the wireless transmission circuit 115. The electronic device is, for example, a desktop computer or a notebook computer, and the wireless communication function of the wireless transmitting circuit 115 can be Bluetooth or Radio Frequency (RF). The control circuit 125 is, for example, a related circuit having an arithmetic processing capability such as a processor or a controller, but the present invention is not limited thereto.

Moreover, the control circuit 125 transmits the generated power switching signal to the power switching circuit 130 when the wireless charging mouse 1 is moved, and the power switching circuit 130 can selectively increase the operating power and reduce the charging power according to the power switching signal. For example, when the wireless charging mouse 1 is moved, if the operating circuit 140 maintains normal operation or the power required for full-speed operation exceeds the battery power that the rechargeable battery 135 can supply, it can improve the operating power and reduce the charging power. The electrical energy required to operate the circuit 140 may be provided mostly or entirely by the operational power output by the power switching circuit 130. Conversely, the power switching signal generated by the control circuit 125 when the wireless charging mouse 1 is not moved is to cause the power switching circuit 130 to selectively reduce operating power and boost charging power. For example, when the wireless charging mouse 1 is not moved, if the power required by the operating circuit 140 can be completely supplied by the rechargeable battery 135, the power switching circuit 130 can reduce the operating power and increase the charging power. The electrical energy required to cause the operational circuit 140 to operate can be provided mostly or entirely by the battery power output by the rechargeable battery 135, and can simultaneously accelerate the charging speed of the rechargeable battery 135.

In addition, in an embodiment, the power switching circuit 130 can implement the above-mentioned power supply adjustment of the operating power and the charging power, for example, through a step-up/step-down converter. For example, the step-up/step-down converter can control the voltage level of the output voltage Vo of the operating power or the charging voltage Vc of the charging power. Similarly, the step-up/step-down converter can also control the output voltage Vo of the operating power. Or the voltage level of the charging voltage Vc of the charging power is lowered. However, it should be noted that the implementation of the power conversion circuit 130 of the present invention is not limited thereto.

For an embodiment in which the power switching circuit 130 adjusts the ratio of the electric energy of the operating electric energy and the charging electric energy, the following description will be given. When the wireless charging mouse 1 is not moving, the control circuit 125 generates a power switching signal, so that the power switching circuit 130 can use 80% of the electrical energy output by the wireless power receiving circuit 105 as charging power, and the remaining 20 % electrical energy is used as operating energy. Conversely, when the wireless charging mouse 1 is moving, the power switching signal generated by the control circuit 125 causes the power switching circuit 130 to use 90% of the electrical energy output by the wireless power receiving circuit 105 as the operating power, and the remaining 10 % electrical energy is used as charging power. The proportion of the electric energy is differently designed by the skilled person in the field according to the user's operation of the mouse habit, and the invention is not limited thereto.

In addition, in an embodiment, when the wireless charging mouse 1 moves, the control circuit 125 may detect whether the power of the rechargeable battery 135 is higher than a preset value before outputting the power switching signal. For example, it is 90% of the power required to operate the circuit 140 at full speed. Therefore, when the control circuit 125 determines that the power of the rechargeable battery 135 is higher than a preset value, the control circuit 125 may not output the power switching signal to the power switching circuit 130.

Each of the wireless power transmitting circuits 210 further includes a wireless power transmitting module and a magnetic coil. The power supply circuit 205 is connected to the power transmitted by the external power source through the connection terminal, wherein the connection terminal is implemented, for example, by a universal serial bus (USB) connector.

In addition, in an embodiment, the control circuit 125 can determine whether the wireless charging mouse 1 has moved when the optical image data detected by the displacement detecting circuit 110 changes. For example, the displacement detecting circuit 110 can determine whether the wireless charging mouse 1 has moved according to the difference between the incident light and the reflected light by the light source unit and the receiving unit. In addition, in another embodiment, the control circuit 125 may also determine whether the wireless charging mouse 1 has a movement according to the change of the electromagnetic energy received by the wireless power receiving circuit 105. This portion will be described in detail later.

Therefore, the control circuit 125 can determine whether the wireless charging mouse 1 has a movement and relatively generate a power switching signal through the displacement detecting circuit 110 and transmit the signal to the power switching circuit 130. For example, when the control circuit 125 determines that the output optical image data of the displacement detecting circuit 110 changes, it can be determined that the wireless charging mouse 1 is moved, and the power switching circuit 130 switches the power according to the power generated by the control circuit 125 to improve the operating power and reduce the charging. The electric energy is such that the electric energy required by the operation circuit 140 when the wireless charging mouse 1 is moved is greater than the electric energy required by the charging circuit 120, and the charging voltage V _C output by the power switching circuit at this time may be, for example, smaller than the output voltage V _O . Conversely, for example, when the control circuit 125 determines that the output optical image data amount of the displacement detecting circuit 110 has not changed, the control circuit 125 can determine that the wireless charging mouse 1 is not moved, so the power switching circuit 130 receives the power switching. The signal is to reduce the operating power and increase the charging power to represent that the power required by the operating circuit 140 when the wireless charging mouse 1 is not moved is less than the power required by the charging circuit 120, and the charging voltage V _C output by the power switching circuit 130 at this time is, for example. Greater than the output voltage V _O .

For example, when the user only clicks the left button, the right button or the sliding wheel of the wireless charging mouse 1 and does not move the wireless charging mouse 1, the control circuit 125 can determine that the wireless charging mouse 1 has not moved through the displacement detecting circuit 110. And the control circuit 125 generates the power switching signal according to the power switching circuit 130 to increase the charging power and reduce the operating power, that is, the electromagnetic energy wirelessly received by the wireless charging mouse through the charging board can be mostly or completely charged.

Conversely, when the user moves the wireless charging mouse 1 on the charging board 2, the control circuit 125 can determine that the wireless charging mouse 1 is moving through the displacement detecting circuit 110, and the control circuit 125 switches the signal according to the power generated by the control circuit 125. In order for the power switching circuit 130 to increase the operating power and reduce the charging power, that is, the electromagnetic energy wirelessly received by the wireless charging mouse 1 through the charging pad 2 can be used as the operating power. In addition, the number and arrangement positions of the wireless power transmitting circuits shown in the charging board 2 of FIG. 3 are merely illustrative and are not intended to limit the present invention.

In addition, the wireless power transmitting circuit 210a is an output that can supply a larger electromagnetic energy to the wireless charging mouse 1 than the wireless power transmitting circuit 210b. In addition, it is worth noting that the wireless charging mouse 1 shown in FIG. 4 receives the change in the electromagnetic quantity provided by the charging pad 2a through the wireless power receiving circuit 105, and determines that the wireless charging mouse 1 is moved, and the wireless charging mouse 1 Receiving electricity through wireless power The path 105 receives that the electromagnetic quantity supplied from the charging pad 2a does not change and concludes that the wireless charging mouse 1 has not been moved. For example, when the wireless charging mouse 1 moves to the position of one of the wireless power transmitting circuits 210b on one of the wireless power transmitting circuits 210a on the charging pad 2a, or the wireless charging mouse 1 is on the charging pad 2a. When the position of one wireless power transmitting circuit 210b is moved to the position of another wireless power transmitting 210a. The control circuit 125 in the wireless charging mouse 1 knows through the wireless power receiving circuit 105 that the received electromagnetic quantity changes, for example, when the electromagnetic energy received by the wireless charging mouse 1 is changed from the first electromagnetic energy to the second electromagnetic energy, the control is performed. The circuit 125 can then assume that the wireless charging mouse 1 has been moved. On the other hand, when the position of one of the wireless power transmitting circuit 210a or the wireless power transmitting circuit 210b of the wireless charging mouse 1 on the charging pad 2a is stationary, the control circuit 125 in the wireless charging mouse 1 receives the wireless power. The circuit 105 knows that the received electromagnetic quantity has not changed, and accordingly determines that the wireless charging mouse 1 has not been moved.
