请同时参阅图2与图3所示，图3为本实用新型实施例的无线充电装置的操作示意图。在本实施例中，用户可以利用无线充电鼠标1来操作笔记本电脑3的光标移动。当无线充电鼠标1接近充电板2在预设距离以内时，此时控制电路120通过转换电路135检测到的电位能高于预设电位能，因此，控制电路120判断无线充电鼠标1已经接近充电板2，控制电路120通过无线发射电路110输出第一控制信号至无线接收电路215，充电板2从第二供电模式切换至第一供电模式。相反地，当无线充电鼠标1被抬高离充电板2预设距离以外时，控制电路120通过转换电路135检测到的电位能低于预设电位能时，控制电路120判断无线充电鼠标1已经离开充电板2，控制电路120输出第二控制信号至无线接收电路215，充电板2从第一供电模式切换至第二供电模式。第一供电模式的充电功率大于第二供电模式的充电功率。换句话说，当控制电路120判断无线充电鼠标1已经接近充电板2时，充电板2以较高的充电功率供电至无线充电鼠标1，当控制电路120判断无线充电鼠标1已经离开充电板2时，充电板2提供较低的充电功率供电。本实用新型所提出的无线充电装置具有动态调整充电板2的供电模式的功能，可有效降低充电板2的耗能。Please refer to FIG. 2 and FIG. 3 at the same time. FIG. 3 is a schematic diagram of the operation of the wireless charging device according to the embodiment of the present invention. In this embodiment, the user can use the wireless charging mouse 1 to operate the cursor movement of the notebook computer 3 . When the wireless charging mouse 1 approaches the charging board 2 within a preset distance, the potential energy detected by the control circuit 120 through the conversion circuit 135 is higher than the preset potential energy. Therefore, the control circuit 120 judges that the wireless charging mouse 1 is close to charging. For the board 2, the control circuit 120 outputs the first control signal to the wireless receiving circuit 215 through the wireless transmitting circuit 110, and the charging board 2 switches from the second power supply mode to the first power supply mode. Conversely, when the wireless charging mouse 1 is lifted beyond the preset distance from the charging board 2, and the potential energy detected by the control circuit 120 through the conversion circuit 135 is lower than the preset potential energy, the control circuit 120 judges that the wireless charging mouse 1 has Leaving the charging board 2, the control circuit 120 outputs a second control signal to the wireless receiving circuit 215, and the charging board 2 switches from the first power supply mode to the second power supply mode. The charging power in the first power supply mode is greater than the charging power in the second power supply mode. In other words, when the control circuit 120 judges that the wireless charging mouse 1 is close to the charging board 2, the charging board 2 supplies power to the wireless charging mouse 1 with a higher charging power; when the control circuit 120 judges that the wireless charging mouse 1 has left the charging board 2 , the charging board 2 provides a lower charging power for power supply. The wireless charging device proposed by the utility model has the function of dynamically adjusting the power supply mode of the charging board 2 , which can effectively reduce the energy consumption of the charging board 2 .
