Abstract
The invention discloses an electromagnetic charging device and a using method thereof. The device mainly comprises a wireless radio-frequency receiving unit, a converting circuit and a power storage unit, wherein the wireless radio-frequency receiving unit is used for receiving electromagnetic wave which is dissipated in a free space; the converting circuit is used for converting the electromagnetic wave into electric energy; and the power storage unit is used for storing the electric energy. The using method for the device has the aim that when common wireless communication (or wireless charging) performs energy exchange between a transmitting terminal and a receiving terminal, the dissipated energy is recycled so as to charge matched electronic products and further realize the reutilization of the energy.
Description
Technical field
The invention relates to a kind of charging device and using method thereof, particularly relevant for a kind of electromagnetic charging device and using method thereof with wireless transmission electric power.
Background technology
General consumption electronic products all are to see through the mode that connects power line to charge, and the charging connector of various charger, usually all being also can't be shared at the electronic product that is complementary, quite inconvenient in the use, and the way interleave coiling not only is repugnant to the eye, and also causes certain potential safety hazard.
Based on above-mentioned problem points, the conception of " wireless transmission electric power " begins to be suggested, the researcher of the Massachusetts Institute of Technology (MIT) wherein, a kind of new theory that can utilize " electromagnetic energy " by the wireless power transmission technology is proposed, and in 2007, do not utilizing under the power line, successfully lighting 60 watts of bulbs outside two meters of power supplys.
In the experiment, utilize two copper wire coils (copper coils) to serve as resonator (resonator); And one of them coil links to each other with power supply as reflector (sending unit), and another links to each other with bulb and serves as receiver (receiving unit).The electric power that reflector is sent characteristic frequency (adopting 10MHz in the experiment) shakes behind the ripple, and makes receiver produce resonance on same frequency, just can carry out energy between the two and exchange.Afterwards, scientist claimed that this technology was wireless power transmission technology (WirelessElectricity; Be called for short WiTicitiy), by utilizing basic physics, finally can give electronic product " every empty " charging.
Yet even the researcher of MIT can light bulb, efficient also has only 45% but current experiment conducts electricity, and most electric power all fails to be sent on the receiver.In other words, the electromagnetic wave that produces in the air can one way or another scatters, and carries out energy when exchanging between transmitting terminal and receiving terminal, can be along with the increase of the distance energy that runs off in large quantities.Therefore, most expert is specially grinding, and how to go to reduce the energy turnover rate of receiving terminal, but thinks and these loss energy are utilized again.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of electromagnetic charging device and using method thereof, utilize to receive the electromagnetic recovery notion of scattering and disappearing in free space, further reach the charging effect of wireless power transmission.
Based on above-mentioned purpose, the invention provides a kind of electromagnetic charging device, mainly constituted by a less radio-frequency receiving element, a change-over circuit and a power storage unit.Wherein, the less radio-frequency receiving element is in order to receive the electromagnetic wave that scatters and disappears in free space; Change-over circuit is in order to be converted to electric energy with electromagnetic wave; And power storage unit is in order to store electrical energy.
In addition, its step of using method provided by the present invention comprises: above-mentioned electromagnetic charging device is provided; Then, utilize this electromagnetic charging device, receive in a special frequency channel and scatter and disappear in the electromagnetic wave of free space; At last, convert the electromagnetic wave that this electromagnetic charging device received to electric energy, and store.In addition, in an embodiment of the present invention, the less radio-frequency receiving element can be through adjusting, to receive the electromagnetic wave of different frequency range.In addition, power storage unit for example is a battery body independently, and less radio-frequency receiving element and change-over circuit then can be built and place on the consumption electronic products.Certainly, less radio-frequency receiving element and change-over circuit also can in be built in power storage unit, and integrate.
About preferred embodiment of the present invention and technology contents, cooperate graphic being described as follows now:
