Abstract

The present disclose relates to a wireless charging device for charging a portable electronic device. The wireless charging device includes a charging panel, a transmitting unit and at least one adsorbent unit. The charging panel includes a first surface and a second surface opposite to the first surface. The first surface supports the portable electronic device. The charging panel defines a through hole through the first surface. The transmitting unit includes a coil for generating electromagnetic signals. The adsorbent unit extends through the through hole of the charging panel and adsorbs the portable electronic device.

Claims

1. A wireless charging device for charging a portable electronic device, comprising:

a charging panel comprising a first surface and a second surface opposite to the first surface, the first surface for supporting the portable electronic device, the charging panel defining at least one through hole extending through the first surface;

a transmitting unit comprising a coil for generating electromagnetic signals for charging the portable electronic device; and

at least one adsorbent unit, the adsorbent unit comprising a adsorbent portion passing through the through hole of the charging panel for adsorbing the portable electronic device.

2. The wireless charging device of claim 1, further comprising a power source received in the wireless charging device for providing power source for the transmitting unit.

3. The wireless charging device of claim 1, wherein the adsorbent portion in made of rubber.

4. The wireless charging device of claim 1, wherein the adsorbent portion is a vacuum suction.

5. The wireless charging device of claim 1 comprising two adsorbent units, wherein each adsorbent unit comprises a plurality of adsorbent portions.

6. The wireless charging device of claim 5, wherein the two adsorbent units are arranged on two opposite sides of the transmitting unit.

7. The wireless charging device of claim 1, further comprising a holder for supporting the adsorbent unit.

8. The wireless charging device of claim 1, further comprising two slippery mats arranged on the first surface of the charging panel.

9. The wireless charging device of claim 1, further comprising a bottom cover, the bottom cover and the charging panel cooperatively defining a cavity for receiving the transmitting unit and the adsorbent unit.
