Abstract
The utility model discloses a novel wireless transmitter that charges, including circular circuit board, set up in the control chip of circular circuit board one side, the circular circuit board opposite side is provided with the induction coil of electric energy with the transmission of electromagnetic wave form, induction coil's both ends respectively with control chip is connected, circular circuit board with be provided with electromagnetic shield layer between the induction coil, electromagnetic shield layer's size is greater than induction coil's size is through setting up electromagnetic shield layer between circuit board and induction coil for the electromagnetic wave can only reduce the electromagnetic and reveal towards the conveying of specific direction, thus the charge efficiency of system, the radiation hazradial bundle of greatly reduced's product.
Description
Technical field
The utility model relates to a kind of novel radio charging reflector.
Background technology
The function of machine from strength to strength, disposal ability and amusement performance more and more higher, corresponding energy ezpenditure is also more and more severe; On the other hand, user more and more pursues the frivolous of mobile phone again, battery capacity seems and is a bottleneck, so, mobile phone one day one charging, the phenomenon even will charged half a day is just very common, and being limited by the impact of handset size, charging inlet is very small and exquisite, and corresponding mechanical strength is just not being met, plug of charging so frequently makes mobile phone charging interface be hold flimsy part most, and after repeatedly plugging, contact reliability also has decline, thus contact resistance is caused to become large, and then heating, serious even leads to fire.
Therefore wireless charging technology is just very naturally contemplated by everybody, and traditional wireless charging technology is due to lack of wisdom administrative skill, under charge efficiency, generally all only has 40%; And can emitted energy be continued, even if mobile phone charging terminate after, reflector still according to rated power at emitted energy, both wasted energy, caused electromagnetic radiation.
Summary of the invention
The purpose of this utility model is to overcome the defect existed in prior art, provides a kind of novel radio charging reflector, reduces electromagnetic leakage.
For achieving the above object, the technical solution of the utility model there is provided a kind of novel radio charging reflector, comprise circle line plate, be arranged at the control chip of described circle line plate side, described circle line plate opposite side is provided with the induction coil launched with electromagnetic wave by electric energy, the two ends of described induction coil are connected with described control chip respectively, be provided with electro-magnetic screen layer between described circle line plate and described induction coil, the size of described electro-magnetic screen layer is greater than the size of described induction coil.
Further improvement: described electro-magnetic screen layer comprise be made up of ferrite antifreeze plate, bag be located at the diaphragm on described antifreeze plate surface and be arranged at the gum being convenient to location and installation transmitting coil of described antifreeze plate side.
Further improvement: described electro-magnetic screen layer is provided with temp probe, described temp probe is positioned at the center of described induction coil, and described temp probe is connected with described control chip by wire.
Advantage of the present utility model and beneficial effect are: by arranging electro-magnetic screen layer between wiring board and induction coil, electromagnetic wave can only be transmitted towards specific direction, decrease electromagnetic leakage, thus system charge efficiency, the radiation hazradial bundle of the product greatly reduced.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is rearview of the present utility model.
Wherein: 1, circle line plate; 2, control chip; 3, induction coil; 4, temp probe; 5, electro-magnetic screen layer.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection range of the present utility model with this.
As shown in Figure 1, a kind of novel radio charging reflector, comprise circle line plate 1, be arranged at the control chip 2 of described circle line plate 1 side, described circle line plate 1 opposite side is provided with the induction coil 3 launched with electromagnetic wave by electric energy, the two ends of described induction coil 3 are connected with described control chip 2 respectively, be provided with electro-magnetic screen layer 5 between described circle line plate 1 and described induction coil 3, the size of described electro-magnetic screen layer 5 is greater than the size of described induction coil 3.
Operation principle: by arranging electro-magnetic screen layer 5 between the circle line plate 1 and induction coil 3 of reflector, in addition wireless charging receiver is provided with electro-magnetic screen layer 5 accordingly, then electromagnetic wave signal can only transmit between two electro-magnetic screen layers 5, improve system charge efficiency, the radiation hazradial bundle of the product greatly reduced, reduces electromagnetic leakage to greatest extent.
In order to improve the shield effectiveness of electro-magnetic screen layer 5, described electro-magnetic screen layer 5 comprise described electro-magnetic screen layer comprise be made up of ferrite antifreeze plate, bag be located at the diaphragm on described antifreeze plate surface and be arranged at the gum being convenient to location and installation transmitting coil of described antifreeze plate side.
In order to avoid producing microwave oven effect, ensure use safety, described electro-magnetic screen layer 5 is provided with temp probe 4, described temp probe 4 is positioned at the center of described induction coil 3, described temp probe 4 is connected with described control chip 2 by wire, when being detected the variations in temperature of reflector by temp probe 4 thus judged whether emitter surface has a metallic foreign body, when there being metallic foreign body, reflector quits work.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
