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, the coil being fixed on the fixing member, the coil receiving an external electromagnetic signal to generate an induction current;

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; and

a circuit board electrically connected with the coil and comprising a first part and a second part bended from a side of the first part;

wherein the first part of the circuit board and the fixing member are arranged on a top surface of the battery side by side, and the second part of the circuit board is located at a lateral side of the battery.

2. The charging battery unit of claim 1, further comprising a detecting unit arranged on the first part of the circuit board for detecting the quantity of electricity of the battery.

3. The charging battery unit of claim 2, further comprising a display unit arranged on the first part of the circuit board 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. 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, a circuit board, and a battery, the receiving unit comprising a fixing member and a coil, the coil being 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 circuit board electrically connected with the coil and comprising a first part and a second part bended from a side of the first part, the receiving unit being attached to the battery by the fixing member;

the first part of the circuit board and the fixing member are arranged on a top surface of the battery side by side, and the second part of the circuit board is located at a lateral side of the battery.

6. The electronic device of claim 5, further comprising a detecting unit arranged on the first part of the circuit board for detecting the quantity of electricity of the battery.

7. The electronic device of claim 6, further comprising a display unit arranged on the first part of the circuit board for displaying the quantity of electricity of the battery detected by the detecting unit.

8. The electronic device of claim 7, wherein the display unit comprises two LEDs, and the LEDs emit light when the battery is fully charged.
