請參照圖1，圖1係為根據本案之無線電力傳送裝置之一實施例之示意圖。無線電力傳送裝置1包含能收發無線電力之無線供電單元11及無線受電單元12。無線供電單元11具有來自插座或電池之電源而能主動地發射無線電力訊號。無線受電單元12則能根據無線供電單元11發射之無線電力訊號而取得電力，在取得電力之後，無線受電單元12亦能發射無線電力訊號，進而溝通於無線供電單元11。Please refer to FIG. 1. FIG. 1 is a schematic diagram of an embodiment of a wireless power transmission device according to the present application. The wireless power transmission device 1 includes a wireless power supply unit 11 and a wireless power receiving unit 12 capable of transmitting and receiving wireless power. The wireless power supply unit 11 has a power source from a socket or a battery and can actively transmit wireless power signals. The wireless power receiving unit 12 can obtain power according to the wireless power signal transmitted by the wireless power supply unit 11. After the power is obtained, the wireless power receiving unit 12 can also transmit the wireless power signal to communicate with the wireless power supply unit 11.

在運作時，無線供電單元11先發射一無線電力訊號S1（為方便描述，以下稱為第一無線電力訊號S1），無線受電單元12接收無線供電單元11發射之第一無線電力訊號S1而取得電力，無線受電單元12接著回應一無線電力訊號S2（為方便描述，以下稱為第二無線電力訊號S2）給無線供電單元11，無線供電單元11自無線受電單元12接收第二無線電力訊號S2之後即偵測第二無線電力訊號S2的電力資訊，並根據第二無線電力訊號S2的電力資訊產生用以表示無線受電單元12與無線供電單元11之間之相對位置之相對位置資訊，使無線電力傳送裝置1之使用者能根據無線受電單元12與無線供電單元11之間之相對位置資訊調整無線受電單元12與無線供電單元11之擺放位置，使無線受電單元12對準無線供電單元11而提高無線電力傳送裝置1之供電及受電效率，無線電力傳送裝置1能正常地工作。During operation, the wireless power supply unit 11 first transmits a wireless power signal S1 (for convenience of description, hereinafter referred to as the first wireless power signal S1), and the wireless power receiving unit 12 receives the first wireless power signal S1 transmitted by the wireless power supply unit 11 to obtain The wireless power receiving unit 12 then responds to the wireless power supply unit 11 with a wireless power signal S2 (for convenience of description, hereinafter referred to as the second wireless power signal S2), and the wireless power supply unit 11 receives the second wireless power signal S2 from the wireless power receiving unit 12 After that, the power information of the second wireless power signal S2 is detected, and relative position information indicating the relative position between the wireless power receiving unit 12 and the wireless power supply unit 11 is generated based on the power information of the second wireless power signal S2, so that the wireless The user of the power transmission device 1 can adjust the placement position of the wireless power receiving unit 12 and the wireless power supply unit 11 according to the relative position information between the wireless power receiving unit 12 and the wireless power supply unit 11, so that the wireless power receiving unit 12 is aligned with the wireless power supply unit 11 To improve the power supply and power receiving efficiency of the wireless power transmission device 1, the wireless power transmission device 1 can work normally.

在一實施例中，無線供電單元11可將第二無線電力訊號S2的電力資訊轉換為相應之數位值，且前述數位值係一對一對應於表示距離資訊之一距離值。於是，在無線電力傳送裝置1運作之前，設計者可將前述表示電力資訊之數位值與表示距離資訊之一距離值之間的一對一對應關係儲存於無線供電單元11；在無線電力傳送裝置1運作時，無線供電單元11偵測出第二無線電力訊號S2的電力資訊之後，無線供電單元11能藉由前述之預先儲存之對應關係以第二無線電力訊號S2的電力資訊之數位值進行查表而得到對應之距離值。請參照圖2，圖2示例出相應於電力資訊之數位值與相應於距離資訊之距離值之間之對應關係（縱軸係表示相應於電力資訊之數位值，橫軸係表示相應於距離資訊之距離值），且相應於電力資訊之數位值與相應於距離資訊之距離值之間呈現負相關。在無線供電單元11偵測第二無線電力訊號S2之電力資訊之後，若無線供電單元11得到相應於第二無線電力訊號S2之電力資訊之數位值係為「100」，無線供電單元11可根據圖2所示例之對應關係得到相應之距離值為「15」。In one embodiment, the wireless power supply unit 11 can convert the power information of the second wireless power signal S2 into a corresponding digital value, and the digital value is one-to-one corresponding to a distance value representing the distance information. Therefore, before the wireless power transmission device 1 operates, the designer can store the one-to-one correspondence between the aforementioned digital value representing power information and a distance value representing distance information in the wireless power supply unit 11; 1. In operation, after the wireless power supply unit 11 detects the power information of the second wireless power signal S2, the wireless power supply unit 11 can use the aforementioned pre-stored correspondence relationship to use the digital value of the power information of the second wireless power signal S2. Look up the table to get the corresponding distance value. Please refer to Figure 2. Figure 2 illustrates the correspondence between the digital value corresponding to the power information and the distance value corresponding to the distance information (the vertical axis represents the digital value corresponding to the power information, and the horizontal axis represents the corresponding distance information The distance value), and there is a negative correlation between the digital value corresponding to the power information and the distance value corresponding to the distance information. After the wireless power supply unit 11 detects the power information of the second wireless power signal S2, if the wireless power supply unit 11 obtains the digital value of the power information corresponding to the second wireless power signal S2 as "100", the wireless power supply unit 11 can follow The corresponding relationship shown in Figure 2 obtains the corresponding distance value of "15".

進一步，在無線供電單元11根據第二無線電力訊號S2的電力資訊得到表示距離資訊之距離值之後，無線供電單元11可根據距離值與一預設值產生表示無線受電單元12「已對準」無線供電單元11或無線受電單元12「未對準」無線供電單元11之相對位置資訊。詳細而言，無線供電單元11在得到距離值之後比較距離值與預設值，以圖2所示例之表示電力資訊之數位值與距離值之間呈現負相關為例，若無線供電單元11判斷距離值大於或等於預設值，表示無線供電單元11遠離無線受電單元12，如此將影響供電與受電效率，此時，無線供電單元11產生表示無線受電單元12「未對準」無線供電單元11之相對位置資訊；相反地，若無線供電單元11判斷距離值小於預設值，表示無線供電單元11係鄰近無線受電單元12而不影響供電與受電效率，或是受影響之供電效率及受電效率尚在可容許範圍內，此時，無線供電單元11產生表示無線受電單元12「已對準」無線供電單元11之相對位置資訊。Further, after the wireless power supply unit 11 obtains the distance value representing the distance information according to the power information of the second wireless power signal S2, the wireless power supply unit 11 may generate a signal indicating that the wireless power receiving unit 12 is "aligned" according to the distance value and a preset value. The wireless power supply unit 11 or the wireless power receiving unit 12 is "not aligned" with the relative position information of the wireless power supply unit 11. In detail, after obtaining the distance value, the wireless power supply unit 11 compares the distance value with the preset value. Take the negative correlation between the digital value representing the power information and the distance value illustrated in FIG. 2 as an example, if the wireless power supply unit 11 determines The distance value is greater than or equal to the preset value, indicating that the wireless power supply unit 11 is far away from the wireless power receiving unit 12, which will affect the power supply and power receiving efficiency. At this time, the wireless power supply unit 11 generates a signal indicating that the wireless power receiving unit 12 is "not aligned" with the wireless power supply unit 11. Conversely, if the wireless power supply unit 11 determines that the distance value is less than the preset value, it means that the wireless power supply unit 11 is adjacent to the wireless power receiving unit 12 without affecting the power supply and power receiving efficiency, or the power supply efficiency and power receiving efficiency are affected It is still within the allowable range. At this time, the wireless power supply unit 11 generates relative position information indicating that the wireless power receiving unit 12 is “aligned” with the wireless power supply unit 11.

舉例來說，前述之預設值可為「10」，以無線供電單元11得到之距離值為「15」為例，無線供電單元11可根據為「10」之預設值判斷出為「15」之距離值大於預設值，進而產生表示無線受電單元12「未對準」無線供電單元11之相對位置資訊；以無線供電單元11根據第二無線電力訊號S2的電力資訊得到之距離值為「3」為例，無線供電單元11可根據為「10」之預設值判斷出為「3」之距離值小於預設值，進而產生表示無線受電單元12「已對準」無線供電單元11之相對位置資訊。基此，無線電力傳送裝置1之使用者能根據無線供電單元11產生之相對位置資訊得知無線受電單元12是否已對準無線供電單元11。For example, the aforementioned default value can be "10". Taking the distance value obtained by the wireless power supply unit 11 as "15" as an example, the wireless power supply unit 11 can determine that it is "15" based on the default value of "10". "" is greater than the preset value, and then generates relative position information indicating that the wireless power receiving unit 12 is "not aligned" with the wireless power supply unit 11. The distance value obtained by the wireless power supply unit 11 according to the power information of the second wireless power signal S2 is Take "3" as an example, the wireless power supply unit 11 can determine that the distance value of "3" is less than the preset value based on the default value of "10", and then generate an indication that the wireless power receiving unit 12 is "aligned" with the wireless power supply unit 11. The relative position information. Based on this, the user of the wireless power transmission device 1 can know whether the wireless power receiving unit 12 is aligned with the wireless power supply unit 11 according to the relative position information generated by the wireless power supply unit 11.

在另一實施例中，相對位置資訊除了表示無線供電單元11「對準」或「未對準」無線受電單元12之外，相對位置資訊亦可包含前述之距離值，也就是無線供電單元11在以數位值進行查表後可直接輸出相應之距離值作為無線受電單元12與無線供電單元11之間之相對位置資訊。In another embodiment, in addition to indicating that the wireless power supply unit 11 is "aligned" or "misaligned" with the wireless power receiving unit 12, the relative position information may also include the aforementioned distance value, that is, the wireless power supply unit 11 After checking the table with the digital value, the corresponding distance value can be directly output as the relative position information between the wireless power receiving unit 12 and the wireless power supply unit 11.

在一實施例中，前述之第二無線電力訊號S2之電力資訊係為電壓值，也就是無線供電單元11係偵測第二無線電力訊號S2之電壓值大小並將其轉換為數位值。再者，前述之表示距離資訊之距離值可為無線供電單元11與無線受電單元12之間之一直線距離或無線供電單元11與無線受電單元12之間之一相對錯位距離，也就是無線供電單元11產生之相對位置資訊亦可為無線供電單元11與無線受電單元12之間之直線距離資訊或是錯位距離資訊。在另一些實施例中，第二無線電力訊號S2之電力資訊亦可為電流值或功率值。In one embodiment, the power information of the aforementioned second wireless power signal S2 is a voltage value, that is, the wireless power supply unit 11 detects the voltage value of the second wireless power signal S2 and converts it into a digital value. Furthermore, the aforementioned distance value representing the distance information can be a linear distance between the wireless power supply unit 11 and the wireless power receiving unit 12 or a relative misalignment distance between the wireless power supply unit 11 and the wireless power receiving unit 12, that is, the wireless power supply unit The relative position information generated by 11 can also be linear distance information or misalignment distance information between the wireless power supply unit 11 and the wireless power receiving unit 12. In other embodiments, the power information of the second wireless power signal S2 may also be a current value or a power value.
