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 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.
無線電力接收電路105中更包括有共振電路以及磁力線圈。共振式無線充電是相當有效率的傳輸方式,電磁能發射端與電磁能接收端設定為相同的共振頻率,就能達到磁共振偶合(Resonant Magnetic Coupling)。具體來說,本實施例提供無線電力接收電路105中的磁力線圈與充電板的無線發射電路的磁力線圈進行電磁耦合時,無線充電滑鼠1就能以無線方式接收到充電板傳送的電磁能。在本實施例中,無線電力接收電路105電性連接充電電路125。充電電路125包括有濾波以及整流的功能,將無線電力接收電路105所接收的電磁能經濾波以及整流後傳送至充電電池130以作為儲備電能。充電電池130並提供操作電路135中的無線發射電路110、位移偵測電路115、控制電路120操作電能所需。 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.
位移偵測電路115用以偵測無線充電滑鼠1的移動,換句話說,位移偵測電路115可以光學偵測方式來判斷無線充電滑鼠1的移動量以及移動方向,本發明並不以偵測方式為限。位移偵測電路115的光源單元(圖未示)可以為雷射(Laser)或是紅外線(Infrared)照射一平面,位移偵測電路115的接收單元(圖未示)可接收此平面所反射的雷射或是紅外線,藉由入射光與反射光的差異 值來計算出無線充電滑鼠1的移動量以及移動方向。 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 present invention does not The detection method is limited. 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.
控制電路120根據位移偵測電路110的偵測結果相對產生位移偵測訊號。控制電路125可將位移偵測訊號傳送至無線發射電路110,透過無線發射電路110的無線通訊功能將位移偵測訊號輸出至無線接收器(圖未示)。無線接收器例如以插接在電腦裝置USB接孔上的dongle來實現,無線接收器也可以為置於電腦裝置的內部。無線發射電路115的無線通訊功能可以為藍芽(Bluetooth)或是無線射頻(RF)。 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. The wireless receiver is implemented, for example, by a dongle that is plugged into the USB jack of the computer device, and the wireless receiver can also be placed inside the computer device. The wireless communication function of the wireless transmitting circuit 115 can be Bluetooth or Radio Frequency (RF).
控制電路120接收無線電力接收電路105所傳送的電磁能,且控制電路120根據位移偵測電路的偵測結果而相對產生位移偵測訊號。控制電路120透過無線發射電路110輸出位移偵測訊號至無線接收器。其中當控制電路120於無線充電滑鼠1的無線電力接收電路105所接收的電磁能低於預設電磁能時,控制電路120即停止輸出位移偵測訊號至無線接收器。進一步說明,當無線電力接收電路105所接收的電磁能低於預設電磁能可能為使用者將無線充電滑鼠1向上抬高而未接觸充電板,控制電路120即可根據此一狀況停止輸出位移偵測訊號至無線接收器,以有效防止因使用者以此方式操作無線充電滑鼠時,無線充電滑鼠1仍繼續偵測移動的誤判輸出。 The control circuit 120 receives the electromagnetic energy transmitted by the wireless power receiving circuit 105, and the control circuit 120 relatively generates the displacement detecting signal according to the detection result of the displacement detecting circuit. The control circuit 120 outputs the displacement detecting signal to the wireless receiver through the wireless transmitting 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. The motion detection signal is transmitted to the wireless receiver to prevent the wireless charging mouse 1 from continuing to detect the false positive output of the mobile when the user operates the wireless charging mouse in this manner.
當無線充電滑鼠1的無線電力接收電路105所接收的電磁能低於預設電磁能時,為了防止無線接收器誤判位移偵測訊號,控制電路120即停止輸出位移偵測訊號。其中,控制電路120停止輸出位移偵測訊號例如可以是控制無線發射電路110停止發射訊號;或是控制電路120停止輸出位移偵測訊號也可以為控制位移偵測電路115停止偵測無線充電滑鼠1的移動。 When the electromagnetic energy received by 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 in order to prevent the wireless receiver from misjudged the displacement detecting signal. The control circuit 120 stops outputting the displacement detection signal, for example, to control the wireless transmission circuit 110 to stop transmitting the signal; or the control circuit 120 stops outputting the displacement detection signal, and the control displacement detection circuit 115 stops detecting the wireless charging mouse. 1 move.
另外,在一實施例中,控制電路120也可以於無線充電滑鼠1所接收的電磁能低於預設電磁能,且持續時間超過一預設時間時才停止輸出位移偵測訊號。因此,藉由此一判斷方式,可以避免 因使用者僅極短暫時間內將無線充電滑鼠提離充電板或是充電板傳輸給無線充電滑鼠1的電磁能短暫變化時而停止輸出位移偵測訊號。舉例來說,當無線電力接收電路105偵測到所接收的電磁能低於預設電磁能,且持續時間超過10毫秒時,控制電路120判斷出無線充電滑鼠已經被提高離充電板一段距離時,控制電路120即停止輸出位移偵測訊號。 In addition, in an embodiment, the control circuit 120 can also stop outputting the displacement detection signal when the electromagnetic energy received by the wireless charging mouse 1 is lower than the preset electromagnetic energy and the duration exceeds a preset time. 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.
當控制電路120於無線充電滑鼠1所接收的電磁能高於預設電磁能時,控制電路120透過無線發射電路110輸出位移偵測訊號至無線接收器。換句話說,當無線充電滑鼠1放置在充電板上操作時,控制電路120可判斷無線充電滑鼠1正持續穩定接收充電板所傳送的電磁能時,因此無線發射電路110即輸出位移偵測訊號至無線接收器,用以進一步控制電腦裝置中顯示面板上的游標。 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.

Each of the wireless power transmitting circuits 210 is electrically connected to the power supply circuit 205. Each of the wireless power transmitting circuits 210 further includes a resonant circuit and a magnetic coil. The power supply circuit 205 is connected to the external power supply through the connection terminal, and the connection terminal is realized by, for example, a universal serial bus (USB) connector. The power supply circuit 205 transmits electromagnetic energy to the wireless charging mouse 1 through each of the wireless power transmitting circuits 210.
請復參閱圖2所示,充電板2具有複數個無線電力發射電路210,當無線充電滑鼠1位於任意相鄰兩無線電力發射電路210之間時,無線充電滑鼠1的無線電力接收電路110接收的電磁能高於預設電磁能。本領域所屬技術人員得以了解磁力線為三維的曲線,因此,在本實施例中,任意相鄰兩無線電力發射電路210的 間距設計是使得位在其中的無線充電滑鼠1接收的電磁能高於預設電磁能,用以避免無線充電滑鼠1放置在充電板2使用卻被誤判提高離充電板2一段距離。 Referring to FIG. 2, the charging board 2 has a plurality of wireless power transmitting circuits 210. When the wireless charging mouse 1 is located between any two adjacent wireless power transmitting circuits 210, the wireless power receiving circuit of the wireless charging mouse 1 The electromagnetic energy received by 110 is higher than the preset electromagnetic energy. Those skilled in the art can understand that the magnetic lines of force are three-dimensional curves, and therefore, in this embodiment, any two adjacent wireless power transmitting circuits 210 The spacing design is such that the wireless charging mouse 1 located therein receives electromagnetic energy higher than the preset electromagnetic energy, so as to prevent the wireless charging mouse 1 from being placed on the charging board 2 but being misjudged to increase the distance from the charging board 2.

在步驟S520中,由控制電路判斷無線電力接收電路接收電磁能低於預設電磁能是否超過預設時間。若步驟S520判斷為是,則進入步驟S525。若步驟S520判斷為否,則回到步驟S515,將位移偵測訊號輸出至無線接收器。透過步驟S510與步驟S520中,可以避免因使用者僅短暫時間內將無線充電滑鼠提高離充電板一段距離或是充電板傳輸給無線充電滑鼠的電磁能短暫變化時而停止輸出位移偵測訊號。 In step S520, it is determined by the control circuit whether the wireless power receiving circuit receives electromagnetic energy lower than the preset electromagnetic energy for more than a preset time. If the determination in step S520 is YES, the process proceeds to step S525. If the determination in step S520 is no, the process returns to step S515 to output the displacement detection signal to the wireless receiver. Through steps S510 and S520, it is possible to prevent the output displacement detection from being stopped when the user temporarily increases the wireless charging mouse by a distance from the charging board or the electromagnetic energy of the charging board is transmitted to the wireless charging mouse for a short period of time. Signal.
在步驟S525中,控制電路停止輸出位移偵測訊號,例如當使 用者將無線充電滑鼠1向上提高離充電板一段距離時,無線電力接收電路所接收的電磁能低於預設電磁能。其中,控制電路停止輸出位移偵測訊號可以是控制無線發射電路停止發射訊號;或是控制電路停止輸出位移偵測訊號也可以為控制位移偵測電路停止偵測該無線充電滑鼠的移動。 In step S525, the control circuit stops outputting the displacement detection signal, for example, when When the user raises the wireless charging mouse 1 upward by a distance from the charging board, the electromagnetic energy received by the wireless power receiving circuit is lower than the preset electromagnetic energy. The control circuit stops outputting the displacement detection signal to control the wireless transmission circuit to stop transmitting the signal; or the control circuit stops outputting the displacement detection signal, and the control displacement detection circuit stops detecting the movement of the wireless charging mouse.
綜上所述,本發明所提出之無線充電滑鼠的控制電路經由無線電力接收電路判斷出所接收到的電磁能小於預設電磁能後,控制電路即判斷出無線充電滑鼠可能未接觸到充電板,控制電路即停止將位移偵測訊號無線傳送至無線接收器,或停止無線充電滑鼠的位移偵測電路偵測無線充電滑鼠的移動。本發明用以解決當使用者將無線充電滑鼠提起離開充電板或是桌面之瞬間,因光學元件的出射光與入射光的差異造成電腦游標誤判的情形,用以增加偵測無線充電滑鼠的準確性。 In summary, the control circuit of the wireless charging mouse provided by the present invention determines that the received electromagnetic energy is less than the preset electromagnetic energy via the wireless power receiving circuit, and the control circuit determines that the wireless charging mouse may not be in contact with the charging. The control circuit stops transmitting the displacement detection signal wirelessly to the wireless receiver, or stops the wireless charging mouse's displacement detection circuit to detect the movement of the wireless charging mouse. The invention is used for solving the situation that when the user lifts the wireless charging mouse away from the charging board or the desktop, the computer cursor is misjudged due to the difference between the outgoing light and the incident light of the optical component, and the wireless charging mouse is detected. The accuracy.
