Abstract

A soft power wireless transmission induction plate includes a gap adjustment sheet, a shielding sheet and a separation sheet. The gap adjustment sheet includes a power induction module, an LED indication light and an LED indication light bar thereon. Through the power induction module, the present invention can supply power to an external electric appliance having induction coils in a wireless transmission way, achieving the object of wireless power supply. The present invention can decrease its entire thickness effectively to achieve an ultra-thin effect, and uses soft materials, without worrying about cracks and magnetic leakage. The LED indication light is to indicate the charging position and the LED indication light bar is to show the charging state.

Claims

1. A soft power wireless transmission induction plate, comprising:

a power induction module, the power induction module being flexible, the power induction module comprising a plurality of induction coils, the induction coils being annular, the induction coils being arranged and spaced in the form of concentric circles;

a gap adjustment sheet disposed under the power induction module; and

a shielding sheet disposed under the gap adjustment sheet for conducting magnetism and preventing electromagnetic interference and magnetic leakage.

2. The soft power wireless transmission induction plate as claimed in claim 1, further comprising a casing, the casing comprising an upper cover and a bottom board, the casing being to accommodate the power induction module, the gap adjustment sheet and the shielding sheet therein.

3. The soft power wireless transmission induction plate as claimed in claim 1, further comprising a first adhesive layer and a second adhesive layer, the first adhesive layer being disposed between the power induction module and the gap adjustment sheet, the power induction module being attached to an upper surface of the first adhesive layer, the gap adjustment sheet being attached to a lower surface of the first adhesive layer, the second adhesive layer being disposed under the gap adjustment sheet, the gap adjustment sheet being attached to an upper surface of the second adhesive layer, the shielding sheet being attached to a lower surface of the second adhesive layer, the area of the second adhesive layer being substantially equal to that of the gap adjustment sheet.

4. The soft power wireless transmission induction plate as claimed in claim 1, wherein the gap adjustment sheet is a flexible soft sheet, and the thickness of the gap adjustment sheet is selective for adjusting a magnetic gap.

5. The soft power wireless transmission induction plate as claimed in claim 1, wherein the shielding sheet is a soft sheet made of iron powder glue.

6. The soft power wireless transmission induction plate as claimed in claim 1, wherein the separation sheet is a soft sheet made of aluminum.

7. The soft power wireless transmission induction plate as claimed in claim 2, further comprising an LED (light emitting diode) indication light, the LED indication light being located at the center of the power induction module.

8. The soft power wireless transmission induction plate as claimed in claim 2, further comprising an LED indication light bar, the LED indication light bar having a rectangular shape and being located at the periphery of the power induction module.
