Description
Technical field
The utility model relates to electronic technology field, particularly video doorbell and the wireless radio wave receiver based on the radio wave charging.
Background technology
Along with scientific and technological progress, video doorbell with electronic peephole viewer (being referred to as afterwards electronic peephole viewer) is progressively replacing traditional optics opal.As long as the traditional opal on door is taken off, just can new electronic peephole viewer easily be installed by having opal, the function of the existing video doorbell of electronic peephole viewer, also can store visitor's record, even also with the function of safety monitoring.Can either take good care of household safe also can be for daily life increases a lot of facilities, so electronic peephole viewer is just becoming a kind of trend universal rapidly.Electronic peephole viewer generally is comprised of the inside and outside firmware of installing of CCD camera assembly, demonstration and control module, battery and door.Existing electronic peephole viewer is all to adopt merely powered battery basically, such as dry cell or lithium battery.This system works is when standby mode, power consumption is can be very little, can accomplish to be less than 1mA, but, when having the visitor to ring a doorbell, display screen, camera module and doorbell loudspeaker etc. are very large to current drain, and generally can not directly use DC power supply on door, so the system standby time is short, need to frequently change the greatest drawback that battery is this product.
Now, realize that wireless charging is mainly by three kinds of modes, i.e. electromagnetic induction, radio wave and resonant interaction.The most common charging pad solution has just adopted electromagnetic induction at present, by the coil-induced generation current of primary and secondary, thereby energy is transferred to receiving terminal from transmission ends, and this solution provider comprises the companies such as Britain Splashpower, U.S. WildCharge and Fulton Innovation.Radio wave is the comparatively ripe technology of another development, and its basic principle is similar to the crystal receiver of early application.The Powercast of the company that represents in this field means, micro high efficiency receiving circuit of its final development, can capture the radio wave energy of rebounding from wall, when making adjustment with load, keeps galvanic current to press.Only need a transmitter that is arranged on wall body plug, and " mosquito type " receiver that can be arranged on any low-voltage product, just radio wave can be changed into to direct current.Another kind of still technology under study for action is electromagentic resonance.The research team led by the physics professor Marin Soljacic of the Massachusetts Institute of Technology (MIT) utilizes this technology to light two meters outer 60 watts of bulbs, and it is named as to WiTricity.The coil diameter used in this experiment reaches 50cm, also can't realize commercialization, if dwindle coil dimension, received power also can descend naturally.The contrast of three kinds of schemes is as shown in table 1.
Table 1
The charging technique that electronic peephole viewer adopts on the market at present, to adopt wired charging modes, to adopt electromagnetic induction or electromagentic resonance mode, but all there is more drawback in these two kinds of modes: wired charging modes, power supply bracing wire charging need to be arranged near door or battery will be taken out to charging, inconvenience, troublesome poeration; Electromagnetic induction and electromagentic resonance wireless charging mode, also need to be by power-supply wiring to doorframe, simultaneously, all extra wireless charging coupling module will additionally be installed on doorframe and door leaf, as shown in Figure 1, in figure, 101 is power leads, the 102nd, electromagnetic induction or electromagentic resonance module, the 103rd, doorframe, the 104th, door leaf, the 105th, electronic peephole viewer indoor host computer.This implementation need to be destroyed the existing structure of metope and door, affects outward appearance, is not " wireless charging " truly.
The existing wireless charging scheme in market has had certain improvement on being user-friendly at present, and the user does not need the power taking pond just can realize the automatic charging to main frame.But the defect of this scheme, be to carry out a lot of transformations on door He on wall outside electronic peephole viewer, not only disfeature, and the construction trouble.
