Abstract

A charging battery unit includes a receiving unit and a battery. The receiving unit includes a fixing member and a coil fixed on the fixing member. The coil receives external electromagnetic signals to generate induction currents. The battery is electrically connected to the coil and receives the induction currents generated by the coil. The present disclosure also relates an electronic device with the charging battery unit.

Claims

1. A charging battery unit comprising:

a receiving unit comprising a fixing member and a coil fixed on the fixing member, the coil receiving an external electromagnetic signal to generate an induction current; and

a battery electrically connected to the coil and receiving the induction current generated by the coil, the receiving unit being attached to the battery by the fixing member.

2. The charging battery unit of claim 1, further comprising a detecting unit for detecting the quantity of electricity of the battery.

3. The charging battery unit of claim 2, further comprising a display unit for displaying the quantity of electricity of the battery detected by the detecting unit.

4. The charging battery unit of claim 3, wherein the display unit comprises two LEDs, and the LEDs emit light when the battery is fully charged.

5. The charging battery unit of claim 3, further comprising a circuit board fixed on the battery, wherein the detecting unit and the display unit are arranged on the circuit board.

6. An electronic device comprising:

a main body; and

a charging battery unit being received in the main body, the charging battery unit comprising a receiving unit and a battery, the receiving unit comprising a fixing member and a coil fixed on the fixing member, the coil receiving an external electromagnetic signal to generate an induction current, the battery electrically connected to the coil and receiving the induction current generated by the coil, the receiving unit being attached to the battery by the fixing member.

7. The electronic device of claim 6, further comprising a detecting unit for detecting the quantity of electricity of the battery.

8. The electronic device of claim 7, further comprising a display unit for displaying the quantity of electricity of the battery detected by the detecting unit.

9. The electronic device of claim 8, wherein the display unit comprises two LEDs, and the LEDs emit light when the battery is fully charged.

10. The electronic device of claim 8, further comprising a circuit board, wherein the detecting unit and the display unit are arranged on the circuit board.
