Detailed description of the invention
Make below in conjunction with embodiment and accompanying drawing wireless charging device based on the high-power honeycomb coil of high quality factor a kind of to this utility model and explaining.
As shown in Figure 1, this utility model is a kind of wireless charging device based on high quality factor high-power class honeycomb coil, wherein control circuit and power supply circuits are that half-bridge drive circuit provides stable voltage input, the outfan of half-bridge drive circuit is connected with transmitting coil, receiving coil receives the energy that transmitting coil is launched, the energy rectifying and voltage-stabilizing of reception is become constant unidirectional current by rectification stable pressuring unit, and powers to the load.
As shown in figs 2-4, receive and transmitting coil all uses this honeycomb coil.Being different from general planar spiral winding, honeycomb coil volume is little, and distributed electrical capacity is little, and inductance value is relatively big, and quality factor are high, so many wireless syntonizing coils, oscillator coil and high frequency choke coil etc., coiling the most in such a way.And it rotates a circle, the number of times that wire bends back and forth, frequently referred to break number, Fig. 2-Fig. 4 show the honeycomb coil of 2 breaks.The advantage of universal winding is that volume is little, and distribution capacity is little, and inductance value is big.Honeycomb coil is all to utilize Nidus Vespae coil winding machine to carry out coiling, and break is the most, and distribution capacity is the least.
As it is shown in figure 5, honeycomb coil plane is not parallel with the surfaces of revolution, but intersecting and have a certain degree (about 19 °～25 °), its coiling is typically carried out on automatically or semi-automatically duolateral coil winding machine.Transmitting coil and receiving coil are in energy transfer process, and cellular structure reduces the leakage of space radiation energy to greatest extent, reduce the waste of power supply energy, reduce the loss of transmission energy, promote charge efficiency, and the energy being less lost is eventually transferred to load.
