A COMBINED WIRE-WIRELESS CHARGER FOR SMART PHONE

摘要

The present invention relates to an integrated wired and wireless charger for a smartphone. If the electrode terminal (SB1) of an supplementary battery (SB) is connected to a charging terminal (11) while simultaneously the RX wireless charging part (R) of a smartphone (H) approaches a TX wireless charging part (21), either a wired charging control module (10) or a wireless charging control module (20) is operated first according to the sequential controls of a sequence control part (30) without charging a main battery (MB) and the supplementary battery (SB) together as prior arts to charge either the supplementary battery (SB) or the main battery (MB), and the other of the wired charging control module (10) and the wireless charging control module (20) is operated sequentially to charge the other of the supplementary battery (SB) and the main battery (MB) sequentially. Accordingly, the present invention can be commercialized at once, and it is not necessary to develop a power supply part (P) additionally due to the problem of a power capacity, and the present invention can be sold together with an existing smartphone (H) as a bundle to keep a consumer price little changed as a voltage of 5V, an electric current of 1.8-2A and maximal power of 9W, which are international standards, are maintained to maintain compatibility with the power supply part (P) called as an adapter and currently used for the smartphone.
