A wireless charging scheme based on single chip microcomputer

The utility model relates to the field of wireless charging equipment, in particular to a single-chip-based wireless charging single-chip solution. Wireless charging technology originated from wireless power transmission technology, which can be divided into low-power wireless charging and high-power wireless charging. Electromagnetic induction is often used for low-power wireless charging, such as charging mobile phones. However, the wireless charging of electric vehicles adopts inductive type, and high-power wireless charging often adopts resonance type, which uses the received energy to charge the battery for its own operation. However, the current charging device is not user-friendly in use.

The purpose of the utility model is to solve the above problems, and to provide a single-chip-based wireless charging single-chip solution. The utility model achieves the above purpose through the following technical solutions: a single-chip-based wireless charging single-chip solution, including a base, a flip seat, a transmitting coil and a single-chip control chip, one end of the base is integrally connected with the base shaft column, and the flip seat is provided with a flip The seat shaft column, the base shaft column and the flip seat shaft column are all hollow structures. The rotating shaft is inserted into the base shaft column and the turning base shaft column to connect the turning base and the base together, the fixture frame is integrally formed and connected to the base shaft column, and the transmitting end power conversion circuit, the transmitting end compensation network circuit and the single-chip microcomputer control chip are embedded in the base. , a cylindrical groove is formed on the flip seat, and the transmitting coil is embedded in the cylindrical groove. In order to further improve the performance of the wireless charging single-chip microcomputer based on the single-chip microcomputer, one end of the rotating shaft is fixed with a shaft-side fixing cap, the other end of the rotating shaft is provided with a thread, and the rotating shaft is screwed with an elastic knob through the thread. In order to further improve the performance of the wireless charging microcontroller based on the microcontroller, a wire slot is arranged on the side of the base, and a wire harness fixing piece is installed in the wire slot. In order to further improve the performance of the wireless charging MCU based on single chip microcomputer, the transmitting coil is wirelessly connected to the receiving coil through a magnetic field, and the receiving coil is connected to the rechargeable battery through the power conversion circuit at the receiving end. Wireless charging MCU scheme In order to further improve the performance of the wireless charging MCU based on MCU, a control button is set on the side of the base, and the control button communicates with the MCU control chip. In the above structure, the charging time and output power of the circuit can be detected by a preset program on the microcontroller control chip, and the time control of the microcontroller can be realized by setting the preset time by pressing the button. When charging small objects such as mobile phones, adjust the elastic knob to make the flip seat at a certain angle, put the mobile phone card on the card seat, and lean against the flip seat to charge.

The utility model has the advantages that the wireless charging single-chip microcomputer scheme based on the single-chip microcomputer can adjust any suitable charging angle under the action of the adjusting knob, and the charging time can be controlled and set by the single-chip microcomputer.
