The invention realizes wireless transmission of power supply, and wireless power utilization of minitype electric appliance.
Description
Technical field
The present invention relates to a kind of supply unit, particularly a kind of novel radio power device.
Background technology
Nowadays more and more equipments has entered " wireless penetration " epoch, but wiring trouble when often needing the equipment of plug power supply and desk lamp, little sound equipment etc. to need roving equipment electricity consumption for mobile phone, MP3 etc., the length restriction of connecting line the mobility and the ease for use of equipment, and plug causes wearing and tearing repeatedly, makes the reliability of power supply, fail safe descend.
Summary of the invention
The object of the present invention is to provide a kind of novel radio power device.
In order to reach described purpose, supply unit provided by the invention comprises frequency conversion part, radiating portion and accepts part, described frequency conversion partly is an auto-excitation type frequency changer, 220V with input, the alternating current of 50Hz converts the alternating voltage of 0～10V, the alternating current of 30～80KHz to, outputs to radiating portion again; Described radiating portion partly links to each other with frequency conversion, is the emission panel of thin light plate, and built-in a plurality of transmitting coils that are wrapped on the magnetic conductor convert the electric energy that receives to electromagnetic energy through induction coil and are transferred to and accept part; The described part of accepting, be installed on the electrical appliance, comprise receiving coil, rectifier, filter circuit and voltage stabilizing circuit, receiving coil is wrapped on the magnetic conductor, receiving coil is connected in the input of rectifier, the output of rectifier is connected in the filter circuit, and the filter circuit output voltage is connected on the voltage stabilizing circuit; Described magnetic conductor is a ferrite core.
Beneficial effect of the present invention: the present invention makes power supply realize wireless transmission, realizes small-sized electrical appliance electricity consumption " wireless penetration ", i.e. be not subjected to the restriction of electric wire during electricity consumption, makes power supply safer, reliable.The present invention realizes simply, easy operating.
Description of drawings
Further specify the present invention below in conjunction with the drawings and specific embodiments.
Fig. 1 is frequency conversion partial circuit figure.
Fig. 2 is for accepting part, radiating portion circuit diagram.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, frequency conversion partly is an auto-excitation type frequency changer (this is not given unnecessary details for known technology) among the present invention, when two ends add voltage, form the oscillating circuit of auto-excitation type by oscillator coil in the circuit 9 and triode 10, the 220V of input, the alternating current of 50Hz converts 0～10V to, the alternating voltage U of 30～80KHz
1, be transferred to the radiating portion that is attached thereto.
As shown in Figure 2, as high-frequency alternating current U
1During transmitting coil 7 by radiating portion, when near the transmitting coil 7 receiving coil 8 being arranged, around desktop 6, produce alternating magnetic fields, electric energy is changed into electromagnetic energy be transferred to the receiving coil 8 of accepting part, and near when not having receiving coil 8, transmitting coil is because equiva lent impedance is bigger, very little of the exciting current that wherein passes through, it is minimum that the electric energy of consumption is dropped to, thereby realize that whole radiating portion can realize that the part electric energy transmitting is accepted in the location automatically; Be installed in the part of accepting on the electrical appliance, receiving coil 8 transforms electric energy to electromagnetic energy by electromagnetic conversion, forms alternating voltage U
2, convert interchange to direct current by rectifier 3 rectifications, be transferred in the LC ∏ type filter circuit 4, rectifier output voltage is earlier through capacitor C
1, filtering after the alternating component, filtering capacitor C on inductance L again
2On alternating component few, then almost be straight direct voltage U
i, as the input voltage of voltage stabilizing circuit 5, its current-limiting circuit R voltage-stabiliser tube V-arrangement by voltage stabilizing circuit 5 becomes output voltage U
0With direct current I
L, be input in the electrical appliance to equipment charge or keep its operate as normal.
More than be one of embodiments of the present invention,, do not spend performing creative labour, on the basis of the foregoing description, can do multiple variation, can realize purpose of the present invention equally for those skilled in the art.But this variation obviously should be in the protection range of claims of the present invention.
