WIRELESS POWER TRANSMISSION DEVICE
First Claim
1. A wireless power transmission device for transmitting an electric power to a closed receiver coil of a portable electronic device, said wireless power transmission device comprising:
- a main body;
a first position-limiting bulge disposed within said main body;
a second position-limiting bulge disposed within said main body, and located beside said first position-limiting bulge, wherein a space is defined between said first position-limiting bulge and said second position-limiting bulge; and
a closed transmitter coil disposed within said main body for transmitting said electric power to said closed receiver coil, thereby charging said portable electronic device, wherein said closed transmitter coil is penetrated through said space between said first position-limiting bulge and said second position-limiting bulge, and two sides of said closed transmitter coil are respectively in contact with said first position-limiting bulge and said second position-limiting bulge.

Abstract
A wireless power transmission device includes a main body, a first position-limiting bulge, a second position-limiting bulge, and a closed transmitter coil. The first position-limiting bulge and the second position-limiting bulge are disposed within the main body. A space is defined between the first position-limiting bulge and the second position-limiting bulge. The closed transmitter coil is penetrated through the space. The two sides of the closed transmitter coil are respectively in contact with the first position-limiting bulge and the second position-limiting bulge, so that the closed transmitter coil is shaped as a dumbbell. Since the closed transmitter coil is shaped as a dumbbell, the magnetic flux can be uniformly generated by the electromagnetic effect when the closed transmitter coil is magnetized. Under this circumstance, the wireless charging efficiency is enhanced.
