This kind of Technology Need wire rod connects, and easily causes mechanical damage, and uses inconvenience.
Summary of the invention
The purpose of this utility model is to provide a kind of mobile phone back splint battery of energy wireless charging, by inscription plate (1), switch rod (2), front supporting plate (3), PCBA1(4), PCBA2(5), polymer battery core (6), magnetic sheet coil (7), back cover (8) and top cover (9) form, wherein the deadlocked back side in polymer battery core (6) of magnetic sheet coil (7) is also put into front supporting plate (3) reverse side central authorities together, PCBA1(4) in the reverse side lower end of front supporting plate (3), PCBA2(5) in the reverse side upper end of front supporting plate (3), back cover (8) snaps together by button bit with front supporting plate (3), switch rod (2) and inscription plate (1) are positioned over front supporting plate (3) front downside, and top cover (9) fastens mutually with the draw-in groove of the positive upper end of front supporting plate (3).
The mobile phone back splint battery of described a kind of energy wireless charging, PCBA1(4) and PCBA2(5) comprise LC resonance R network, communication modulation, rectification, R controller, R sampling, charge switch, output pressure regulation, the modules such as battery form, LC resonance R network is connected with battery with charge switch by rectification module, battery outputs to mobile phone by output voltage regulating module, R controller is sampled and monitors to judge whether to need to cut off or open charge switch the voltage of cell voltage and output voltage regulating module by R sampling module, and communication control modulation module is modulated LC resonance R network operating state and sampling data transmitting is delivered to wireless charger at set intervals.
Described a kind of mobile phone back splint battery that can wireless charging, transmits electric energy with wireless charger by electromagnetic coupled during charging, does not need electric wire directly to connect, the mechanical damage while having avoided charging, and improved the convenience of charging and use.
accompanying drawing explanation:
Fig. 1 is the utility model STRUCTURE DECOMPOSITION schematic diagram.
Fig. 2 is the utility model control module schematic diagram.
Fig. 3 is the utility model and wireless charger coupling work schematic diagram.
Fig. 4 is this wireless charger finished product outline drawing.
Fig. 5 is the utility model finished product outline drawing.
embodiment:
Now with example, the utility model is described in further detail by reference to the accompanying drawings.
The utility model relates to a kind of mobile phone back splint battery that can wireless charging, by inscription plate (1), switch rod (2), front supporting plate (3), PCBA1(4), PCBA2(5), polymer battery core (6), magnetic sheet coil (7), back cover (8) and top cover (9) form.
Switch rod (2), front supporting plate (3), back cover (8), top cover (9) are manufactured moulding by mold injection, and material is PC+ABS or other similar materials; PCBA1(4), be PCBA2(5) by techniques such as SMT paster, Reflow Soldering, wave-solderings, components and parts assembling manufacturing to be formed on PCB.
Whole assemble flow is as follows:
A. first coil is glued on magnetic sheet and makes both become as a whole---magnetic sheet coil (7), then magnetic sheet coil (7) is deadlocked at the back side of polymer battery core (6) together, wherein the magnetic sheet of magnetic sheet coil (7) is close to polymer battery core (6).
B. polymer battery core (6) front being close to front supporting plate (3) reverse side central authorities places, PCBA1(4) be positioned over the reverse side lower end of front supporting plate (3), PCBA2(5) be positioned over the reverse side upper end of front supporting plate (3), and then the front supporting plate (3) with above-mentioned accessory is inserted in back cover (8), by the button bit between front supporting plate (3) and back cover (8), both are snapped together.
C. switch rod (2) is positioned in the aperture of the positive lower-left of front supporting plate (3) end, the plate (1) of engraving is affixed in the groove of front supporting plate (3) front downside.
D. top cover (9) be inserted in to the draw-in groove of the positive upper end of front supporting plate (3) and fasten.
During use, only wireless charger need be powered on, back splint battery is put on charger and can charges, and between back splint battery and charger, without any power line, is connected.Back splint battery front side bottom has four LED to show electric weight, when back splint battery fill full after, because unregulated power line connects, directly take away, without the actions such as power line plug, simple operation.
When needs mobile phone charges together with back splint battery, top cover (9) can be taken away, mobile phone inserts back splint battery and top cover (9) is fastened again, and mobile phone is put on charger and starts to charge together with back splint battery, now most of electric power preferentially charges to mobile phone, and then back splint battery is charged.Rear mobile phone and the back splint battery directly taken away charged.If need mobile phone communication or carry out other operations in charging, directly pick up, after having operated, continue to be positioned on charger and charge and proceed, do not need to pull out power line and just can take back splint battery and mobile phone away, and then insert power line and just can charge, very easy to use.
When battery of mobile phone exhausts while needing back splint battery to supplement electric power, mobile phone is inserted to back splint battery, flicking back splint battery lower-left end switch button is about 2 seconds, and back splint battery can supplement electric power by opponent's machine, increases the cruising time of mobile phone.When not needing back splint battery to supplement electric power, flicking switch key can stop about 2 seconds again.
