Wireless charging plane with magnetic field intensity and field distribution regulating function

Abstract

The invention relates to a wireless charging plane with a magnetic field intensity and field distribution regulating function. The wireless charging plane is composed of am energy emission source (1), emission-end magnetic vitraglass material (2), an energy receiving source (4) and receiving-end magnetic vitraglass material (3). The emission-end magnetic vitraglass material (2) is arranged in the energy emission source (1). The receiving-end magnetic vitraglass material (3) is arranged in the energy receiving source (4). Magnetic resonance evanescent field lines of the emission-end magnetic vitraglass material (2) and the receiving-end magnetic vitraglass material (3) are coupled, and accordingly wireless energy transmission is facilitated, and the greatest equivalent permeability real component is achieved on the system operating frequency. Compared with the prior art, the wireless charging plane has the advantages that at the middle-close range, the vitraglass material components with equal special resonant frequency generate resonance to transmit power, allowing transmission efficiency of the novel system to be remarkably increased; even a certain displacement occurs, transmission effect of the system is good; owing to sub-wavelength property and uniform surface magnetic field of the vitraglass material, multi-goal and efficient charging is realized.

Description

technical field [0001] The invention relates to a wireless energy transmission system, in particular to a wireless charging plane with a magnetic field intensity and field distribution regulation effect. Background technique [0002] A long time ago, the use of electromagnetic induction for energy transmission has existed and been applied, such as the automatic card reader on the bus, and the campus card reading system in the school, and now our second-generation ID card has a similar mechanism: A high-frequency magnetic field will be generated near the reading device. Once the chip enters the surrounding coil, an induced voltage will be generated, thereby activating the chip and transmitting the carried information through the coil to be received by the reading device. The most typical example of pure electromagnetic induction energy transmission is a transformer, which consists of two metal spiral rings arranged in a non-contact manner, and the interior is connected to eac...

Problems solved by technology

However, magnetic resonance wireless energy transmission also has its disadvantages. It is also very sensitive to the dislocation displacement between the transmitting end and the receiving end, which will greatly affect the efficiency. The reason is basically the same as the previous electromagnetic induction method, which is not conducive to the realization of multi-objective Large-scale energy transmission
