Reception device for wireless charging
First Claim
1. A reception device for wireless charging, comprising:
- a reception antenna formed in a pattern form in a flexible board and configured to generate an electric current based on a change of magnetism; and
a charging circuit unit configured to convert the electric current generated by the reception antenna into direct current,wherein the charging circuit unit is connected to the reception antenna via the flexible board,wherein the charging circuit unit comprises a power conversion unit configured to convert an induction current generated by the reception antenna into direct current, andwherein the charging circuit unit further comprise comprises at least one of the battery protection unit configured to prevent an excessive rise in voltage output by the power conversion unit and a control unit configured to perform communication with a power transmission unit.

Abstract
Disclosed herein is a reception device for wireless charging. The reception device for wireless charging may include a reception antenna configured to generate an electric current based on a change of magnetism and a charging circuit unit configured to convert the electric current generated by the reception antenna into direct current. The reception antenna and the charging circuit unit may be connected to a flexible board. Accordingly, the reception device can be attached to the casing of a smart terminal while minimizing a change in the thickness of the smart terminal. A task for connecting the antenna and charging circuit unit of the reception device can be eliminated. A wireless charging function can be assigned to a smart terminal by simply replacing the casing of the smart terminal not having the wireless charging function.
