Detailed description of the invention
Transmitting that current wireless electric energy transfer device is used or receiving coil, predominantly planar coil, and planar coil is divided into hollow and one side to be fixed on magnetic material two kinds.Feature of the present utility model is to be adjusted the inductance value of EMR electromagnetic resonance by the spacing adjusting coil and permeability magnetic material.1 to accompanying drawing 6 referring to the drawings, provide detailed description of the invention of the present utility model, are used for being described further this utility model.
Embodiment 1:
In the present embodiment 1, such as Fig. 1 to Fig. 2, magnetic flux layer A chooses permeability magnetic material, mobile winding C is not secured to magnetic flux layer A, according to electromagnetic property, the winding inductance quantity being close to permeability magnetic material is bigger than the inductance value away from permeability magnetic material, by adjusting magnetic flux layer A and the vertical interval of mobile winding C, reaches to change the purpose of inductance value.
When mobile winding C moves close to magnetic flux layer A, the inductance value at mobile winding C two ends increases, and when mobile winding C moves away from magnetic flux layer, the inductance value at mobile winding C two ends reduces.
The structure that the present embodiment provides both can be used as transmitting coil at transmitting terminal, it is also possible to is used as receiving coil at receiving terminal.
Embodiment 2:
In order to obtain more preferable energy acceptance and magnetic field shielding effect, the structure providing embodiment 1 can be extended, such as Fig. 3 to Fig. 4.
The structure of extension includes: the magnetic flux layer A that permeability magnetic material is made, and is close to and is fixed on the fixing winding B of magnetic flux layer A, can in certain vertical range the mobile winding C of movement, and connect fixing winding B and the wire D moving winding C.
Fixing winding B, mobile winding C, wire D can be formed by same plain conductor, it is possible to connect after being coiled into by different conductor;Fix winding B in the present embodiment 2, mobile winding C, wire D are that stagewise connects, and the end of fixing winding B is connected by wire D with first section of mobile winding C.
Fixing winding B is close to and is fixed on magnetic flux layer A ensure transmitting or the reception of electromagnetic field, reduces the phenomenon of leakage field simultaneously.Mobile winding C, according to itself and the spacing distance change of magnetic flux layer A, moves in vertical range, changes fixing winding B, the inductance value of mobile winding C, wire D entirety with this.
The structure that the present embodiment provides both can be used as transmitting coil at transmitting terminal, it is also possible to is used as receiving coil at receiving terminal.
