Problems solved by technology
However, the existing wireless charging method cannot provide different charging power according to the different positions of the mobile phone. If the position of the mobile phone is shifted, the charging efficiency may be reduced, or the charging power may be too large to cause battery damage. Damaged other components
If a fixed mount is used to place the mobile phone, it is also difficult to match mobile phones of various shapes or sizes at the same time

The invention relates to a wireless charging system and a suspension system. The wireless charging system comprises a base and a mobile device. The base comprises a first circuit board and a first coil, wherein the first circuit board is electrically connected to a power supply terminal, and used for receiving a power supply and converting the power supply into charging current; and the coil is arranged on the first circuit board, and used for generating a first magnetic field according to the charging current. The mobile device comprises a mainboard, a second coil, a battery and an isolation device, wherein the mainboard is used for controlling operations of the mobile device; the second coil is arranged on the mainboard and used for generating induction current according to the first magnetic field; the battery is used for receiving the induction current; and the isolation device is arranged between the second coil and the battery so as to prevent the first magnetic field from interfering operations of the battery. According to the invention, a mobile phone can be controlled to suspend in an appropriate position for wireless charging so as to achieve the best charging efficiency and avoid the battery from being damaged.
Description
technical field [0001] The invention relates to a wireless charging system and a suspension system, in particular to a wireless charging system and a suspension system capable of controlling a mobile device to perform wireless charging in a floating state. Background technique [0002] With the development of science and technology and the progress of industry, mobile phones have become an indispensable part of people's lives. In order to be convenient for users to carry, mobile phones are all equipped with batteries for storing power to provide the power needed for operation. However, the power stored in the battery is limited. Before the battery power is exhausted, the user still has to find the location of the socket and carry a charging cable with him to supply power through an external power source, thus reducing the convenience of the mobile phone. In addition, mobile phones are equipped with charging ports for external power supply. However, different brands of mobil...
