Battery charging cradle and mobile electronic device
First Claim
1. A battery charging cradle and mobile electronic device comprising:
- a battery charging cradle incorporating a primary coil which is connectable to an AC power source; and
a mobile electronic device provided with a secondary coil which is operable to be electromagnetically coupled to the primary coil of the battery charging cradle as well as with a rechargeable battery which is rechargeable by electric power which is induced to the secondary coil,wherein the battery charging cradle has a planar, top plate on an upper side thereof, on which the mobile electronic device is detachably mounted, and also incorporates the primary coil so that an AC magnetic flux is induced to a specific portion of the top plate;
wherein the mobile electronic device has a planar, bottom plate to be placed on the top plate of the battery charging cradle, and also has the secondary coil disposed inside the bottom plate;
wherein the secondary coil is a coreless, planar coil formed with a wire material spirally wound in a planar manner, and the battery charging cradle has a positioning portion for arranging the mobile electronic device in place; and
wherein the mobile electronic device is placed, by means of the positioning portion of the battery charging cradle, at a predetermined position in order that the primary coil is electromagnetically coupled to the secondary coil, and AC power is supplied from the primary coil to the secondary coil, and thus the rechargeable battery incorporated in the mobile electronic device is charged.
