Battery cover
DCFirst Claim
1. A battery cover adapted to placing on an RF (radio frequency) emitter for electrically charging in a non-touch induction mode, said battery cover at least comprises:
- a cover used to cover a battery groove of an electric appliance, and having a set of pins directing to said battery groove to electrically connect with chargeable batteries; and
a non-touch induction type electric power generating unit provided in said cover, said non-touch induction type electric power generating unit being adapted to generating RF signals of an RF emitter to generate electric power by inducing, and electrically charging said chargeable batteries through said set of pins,wherein said non-touch induction type electric power generating unit includes;
a first harmonic oscillation circuit having a first coil and being adapted to getting better energy source when it enters an effective RF signal zone of said RF (radio frequency) emitter;
a rectifying wave filtering circuit connecting with said first harmonic oscillation circuit, to make said energy source become electric DC current;
an electric charging circuit connecting with said rectifying wave filtering circuit for charging said chargeable batteries through said set of pins;
a first processing unit connecting with said electric charging circuit to detect state of charging of said chargeable batteries; and
a first modulating circuit connecting between said first processing unit and said rectifying wave-filtering circuit for releasing signals of state of charging by a load changing mode to transmit data through said first coil for inducing by said RF emitter.

Abstract
A battery cover suitable for being used to cover a battery groove of an electric appliance such as a game controller, a remote controller, a mobile phone, a multi-medium player, a wireless mouse, a flashlight, a PDA, a digital camera etc. to generate electric power in a wireless inducing mode, for charging chargeable batteries that can thus supply electric power for operation of an electric appliance. Therefore, when a user is desired to electrically charge the chargeable batteries, it needs not to take the chargeable batteries out of the electric appliance, but needs only to directly place the electric appliance in an effective wireless induction zone to make the battery cover generate electric power in a wireless inducing mode to charge the batteries.
