WIRELESS CHARGING SYSTEM AND PORTABLE ELECTRONIC DEVICE
First Claim
1. A wireless charging system, comprising:
- a stationary portion including a stationary winding and electrically connected to an external power supply, wherein in response to receiving a voltage of the external power supply, the stationary portion generates pulse voltages that are input to the stationary winding, and the stationary winding generates a charging magnetic field due to electromagnetic induction caused by the pulse voltages; and
a mobile portion, the mobile portion including a first magnet, a generator element, and a rechargeable battery;
the generator element including a second magnet, a shaft, and an induction winding, both the first magnet and the induction winding are fixed on the shaft, the induction winding received in the second magnet and electrically connected to the rechargeable battery, and the first magnet, the shaft, and the induction winding being rotatable relative to the second magnet;
wherein the charging magnetic field generates a magnetic force applied to the first magnet, the first magnet, the shaft, and the induction winding are driven to rotate relative to the second magnet causing induction current to be generated in the induction winding due to electromagnetic induction between the second magnet and the induction winding and transmitted to the rechargeable battery to charge the rechargeable battery.

Abstract
A wireless charging system includes a stationary portion and a mobile portion. The stationary portion generates a charging magnetic field due to electromagnetic induction in response to receiving a voltage of an external power supply. The mobile portion includes a first magnet, a generator element, and a rechargeable battery, and the generator element includes a second magnet, a shaft, and an induction winding. Both the first magnet and the induction winding fixed on the shaft, and the induction winding is received in the second magnet. The charging magnetic field generates a magnetic force applied to the first magnet and drives the first magnet, the shaft, and the induction winding to rotate. Thus, the induction winding cuts magnetic force lines of the second magnet and generates induction current to charge the rechargeable battery.
