Abstract

The invention relates to a receiving device for wireless charging. The receiving device for wireless charging may include a receiving antenna configured to generate current based on a change in magnetic force; and a charging circuit unit configured to convert the current generated by the receiving antenna into a direct current. A receiving antenna and a charging circuit unit may be connected to the flexible board. Accordingly, the receiving device can be attached to the case of the smart terminal while minimizing thickness variation of the smart terminal. The task of connecting the antenna and the charging circuit unit of the receiving device can be eliminated. By simply replacing the casing of the smart terminal that does not have the wireless charging function, the wireless charging function can be provided to the smart terminal.

Description

technical field [0001] The present invention relates to a receiving device for wireless charging, and in particular, to a device mounted on a rear case of a terminal such as a smartphone and configured to wirelessly charge the terminal. Background technique [0002] In recent years, as communication and information processing technologies are advanced, the use of portable smart terminals such as smartphones is gradually increasing. As technology develops, new types of terminals with improved performance continue to be released. [0003] In addition, the most widely used charging method is to directly connect an adapter connected to a power source to the smart terminal and use an external power source to charge the smartphone or to connect the adapter to the smart terminal through the USB terminal of the host and use the battery supplied by the host. A method for charging a smart terminal with a USB power supply. [0004] In order to solve the problem that the smart termina...
