下面将提供一个应用实例“二合一平板电脑”。如图3所示，该二合一平板电脑包括平板01、键盘02和支架03，平板01上设有第一控制单元(图中未示出)、磁传感器(图中未示出)、TX控制与电磁转换IC(图中未示出)和发射线圈04，键盘02上设有磁性单元(图中未示出)、RX接收与电磁转换IC(图中未示出)和接收线圈05。An application example "two-in-one tablet computer" will be provided below. As shown in FIG. 3 , the two-in-one tablet computer includes a tablet 01, a keyboard 02 and a stand 03. The tablet 01 is provided with a first control unit (not shown in the figure), a magnetic sensor (not shown in the figure), a TX The control and electromagnetic conversion IC (not shown in the figure) and the transmitting coil 04, the magnetic unit (not shown in the figure), the RX receiving and electromagnetic conversion IC (not shown in the figure) and the receiving coil 05 are arranged on the keyboard 02 .
在两级识别成功时，第一控制单元检测到待充电设备，即键盘02，则开启无线充电功能，发射线圈04发射电磁波，接收线圈05接收电磁波，此时平板01的显示屏上会显示一电磁波能量耦合图，提示用户将键盘02移动至电磁耦合能量最大区域。同时，由于发射线圈04和接收线圈05的相对位置也会对电磁波能量的有效吸收率产生影响，因而，本实例中，接收线圈05采用一旋转机构装配于键盘02的壳体上，图3中该旋转机构具体为一转轴06，这样，接收线圈05可以相对发射线圈04进行旋转以微调至合适角度，以增大电磁波能量的接收面积，提高充电效率。当然，在其他实施例中，发射线圈04也可以设计为位置可调方式。When the two-level recognition is successful, the first control unit detects the device to be charged, that is, the keyboard 02, and then turns on the wireless charging function. The transmitting coil 04 emits electromagnetic waves, and the receiving coil 05 receives electromagnetic waves. At this time, a The electromagnetic wave energy coupling diagram prompts the user to move the keyboard 02 to the area with the maximum electromagnetic coupling energy. At the same time, since the relative position of the transmitting coil 04 and the receiving coil 05 will also affect the effective absorption rate of electromagnetic wave energy, therefore, in this example, the receiving coil 05 is assembled on the housing of the keyboard 02 by a rotating mechanism, as shown in FIG. 3 The rotating mechanism is specifically a rotating shaft 06, so that the receiving coil 05 can be rotated relative to the transmitting coil 04 to fine-tune to an appropriate angle, so as to increase the receiving area of electromagnetic wave energy and improve the charging efficiency. Of course, in other embodiments, the transmitting coil 04 can also be designed in an adjustable manner.
