The invention discloses a wireless charging system, which relates to the technical field of terminals. The wireless charging system has a function of wirelessly charging an electronic handwriting pen while storing the electronic handwriting pen, integration of storage and wireless charging is realized, the length of a wireless charging link is reduced, the use of chips in the link is reduced, the charging efficiency and reliability are improved, and the cost is reduced. The wireless charging system comprises a tablet computer, a wireless keyboard and an electronic handwriting pen, the wireless keyboard comprises a keyboard body, a support and a connecting part, and the connecting part comprises a containing cavity with an opening formed in one end. A first sending device is arranged in the tablet computer, a first receiving device is arranged in the keyboard body, a second sending device is arranged in the containing cavity, and the first receiving device receives alternating current signals sent by the first sending device and then directly transmits the alternating current signals to the second sending device. And the second sending device is used for wirelessly charging the electronic handwriting pen contained in the containing cavity.
Description
technical field [0001] The examples of the present application relate to the technical field of terminals, and in particular to a wireless charging system. Background technique [0002] With the development of science and technology, some electronic products (such as tablet computers) have been equipped with accessories such as wireless keyboards and electronic stylus pens. As an input device, wireless keyboards have the advantage of fast input speed. It is convenient, can realize handwritten text and can carry out identity verification and other advantages. [0003] At present, the electronic stylus is mainly charged in two ways: wired charging and wireless charging. The existing wired charging is usually provided with a wired charging interface on the electronic stylus, and then connected to a power supply device such as an adapter through a cable. The charging method is difficult to achieve the integrity and aesthetics of the electronic stylus. Existing wireless chargin...
