PROTECTIVE CASE FOR MOBILE COMBINES WIRELESS CHARGING AND SELF-POWER GENERATION

摘要

The present invention relates to a protective case for a mobile phone, which cushions the impact from the outside. The protective case comprises: a soft case which is formed to be attached to and detached from the mobile phone, and into which a hard protective plate having an internal space can be integrally insert-injected; a charge unit which has a transmission coil for disseminating a magnetic field to the mobile phone in the protective plate and a transmission module for outputting/controlling the magnetic field in the transmission coil; a power generation unit which has a motor for generating power in the protective plate and a power generation module for supplying the generated power to the transmission module; an operation unit which has a plurality of gears connected to the motor in the protective plate and a storage means for temporarily accumulating energy on the gears; and a supply unit which is provided on the protective plate to be exposed from the case and has a supply means for supplying rotatory power by being engaged with the gears. Therefore, the present invention is effective in protecting a mobile phone by cushioning the impact from the outside, charging a battery at anytime and anywhere through self power generation, and charging the mobile phone without carrying a separate charge cable or charge jack by wirelessly charging the battery.
