FIG. 5 is a flowchart of a method for inputting a wireless charging mouse according to an embodiment of the present invention.

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 charging circuit 125, a rechargeable battery 130, and an operation circuit 135. The operation circuit 135 includes, for example, a displacement detecting circuit 110, a displacement detecting circuit 115, and a control circuit 120. The control circuit 120 is electrically connected to the wireless power receiving circuit 105, the wireless transmitting circuit 110, and the displacement detecting circuit 115. The operation circuit 135 is electrically connected to the rechargeable battery 130 to receive the electrical energy provided by the rechargeable battery 130. The control circuit 120 can also receive or transmit signals through the wireless power receiving circuit 105, the wireless transmitting circuit 110, and the displacement detecting circuit 115.

The wireless power receiving circuit 105 further includes a resonant circuit and a magnetic coil. Resonant wireless charging is a very efficient transmission method. The electromagnetic energy transmitting end and the electromagnetic energy receiving end are set to the same resonant frequency to achieve Resonant Magnetic Coupling. Specifically, in the embodiment, when the magnetic coil in the wireless power receiving circuit 105 is electromagnetically coupled with the magnetic coil of the wireless transmitting circuit of the charging board, the wireless charging mouse 1 can wirelessly receive the electromagnetic energy transmitted by the charging board. . In the embodiment, the wireless power receiving circuit 105 is electrically connected to the charging circuit 125. The charging circuit 125 includes filtering and rectifying functions, and the electromagnetic energy received by the wireless power receiving circuit 105 is filtered and rectified and transmitted to the rechargeable battery 130 as reserve energy. The rechargeable battery 130 and the wireless transmitting circuit 110, the displacement detecting circuit 115, and the control circuit 120 in the operating circuit 135 are required to operate the electrical energy.

The displacement detecting circuit 115 is configured to detect the movement of the wireless charging mouse 1 . In other words, the displacement detecting circuit 115 can determine the moving amount and the moving direction of the wireless charging mouse 1 by optical detection.

The light source unit (not shown) of the displacement detecting circuit 115 can illuminate a plane for laser or infrared, and the receiving unit (not shown) of the displacement detecting circuit 115 can receive the reflection of the plane. Laser or infrared, by the difference between incident and reflected light The value is used to calculate the amount of movement of the wireless charging mouse 1 and the direction of movement.

The control circuit 120 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 110, and output the displacement detection signal to the wireless receiver (not shown) through the wireless communication function of the wireless transmission circuit 110.

When the electromagnetic energy received by the control circuit 120 in the wireless power receiving circuit 105 of the wireless charging mouse 1 is lower than the preset electromagnetic energy, the control circuit 120 stops outputting the displacement detecting signal to the wireless receiver. Further, when the electromagnetic energy received by the wireless power receiving circuit 105 is lower than the preset electromagnetic energy, the user may raise the wireless charging mouse 1 upward without contacting the charging board, and the control circuit 120 may stop output according to the situation.

Therefore, by this way of judgment, it can be avoided The output of the displacement detection signal is stopped when the user temporarily removes the wireless charging mouse from the charging pad or the charging plate transmits the electromagnetic energy to the wireless charging mouse 1 for a short period of time. For example, when the wireless power receiving circuit 105 detects that the received electromagnetic energy is lower than the preset electromagnetic energy and the duration exceeds 10 milliseconds, the control circuit 120 determines that the wireless charging mouse has been raised a distance from the charging board. At this time, the control circuit 120 stops outputting the displacement detection signal.

When the electromagnetic energy received by the control circuit 120 at the wireless charging mouse 1 is higher than the preset electromagnetic energy, the control circuit 120 outputs the displacement detecting signal to the wireless receiver through the wireless transmitting circuit 110. In other words, when the wireless charging mouse 1 is placed on the charging pad, the control circuit 120 can determine that the wireless charging mouse 1 is continuously receiving the electromagnetic energy transmitted by the charging pad, and thus the wireless transmitting circuit 110 outputs the displacement detector. The test signal is sent to the wireless receiver to further control the cursor on the display panel in the computer device.
