The invention discloses a wireless charging transmitting device. The wireless charging transmitting device comprises a transmitting circuit connected with a power supply and at least two layers of coils, wherein each layer of coils at least comprises a coil connected with the transmitting circuit. The area of a transmitting region is increased through the multiple layers of coils, the multiple coils guarantee that a blind region on the transmitting surface is completely covered, and accordingly, a receiving end can automatically align with certain transmitting coil to obtain electricity with no need of accurately aligning with the single coil, and a plurality of the receiving ends can simultaneously obtain electricity from the transmitting coil aligning with the receiving ends without mutual interference. The convenience of the wireless charging device is improved; besides, each coil is controlled by an independent transmitting circuit, so that a plurality of wireless receiving ends implementing the QI standard are charged simultaneously.
Description
technical field [0001] The present invention relates to the technical field of wireless charging, and more specifically, the present invention relates to a wireless charging transmitting device. Background technique [0002] Wireless charging technology is constantly developing and can be applied to a variety of products such as watches, mobile phones, tablets, and laptops. However, the traditional wireless charging pad can only charge a single device, and it must be precisely aligned when charging. When charging is required, it is inconvenient to connect the device to the charging pad, and the connection process takes a long time. For example, the existing QI standard wireless charging transmitter board can only charge one wireless charging receiving end, and requires precise alignment during charging. This method makes wireless charging very inconvenient in use, thus limiting wireless charging technology. development of. [0003] Therefore, in view of the poor convenienc...
