The technical solution adopted in the utility model; its beneficial effect is: give lithium cell charging; on electromagnetic induction coil, produce a large amount of heats; by the protection of heat shield; can completely cut off the heat that electromagnetic induction coil produces; guarantee that battery temperature can not become very high, increased the life-span of battery, eliminated potential safety hazard.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 be the utility model one preferred embodiment blast structural representation.
Fig. 2 is the theory diagram of the utility model one preferred embodiment.
In figure, 1, upper cover; 2, lithium battery module; 3, wireless charging receiver module; 4, electromagnetic induction coil; 5, lower cover; 6, heat shield; 7, screen; 8, temperature sensor; 9, sampling resistor.
Embodiment
Be below specific embodiments of the invention by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiment.
As shown in Figure 1, this wireless charging lithium battery, comprise successively upper cover 1, lithium battery module 2, wireless charging receiver module 3, electromagnetic induction coil 4 and lower cover 5 from top to bottom, lithium battery module 2 is provided with sampling resistor 9, between described wireless charging receiver module 3 and lithium battery module 2, be provided with heat shield 6, heat shield 6 upper surfaces are provided with temperature sensor 8, heat shield 6 belows are provided with screen 7, described electromagnetic induction coil 4 is arranged on screen 7 lower surfaces, described wireless charging receiver module 3 and lithium battery module 2 electrical connections.
Heat shield 6 is made by heat-barrier material, and heat-barrier material can be vacuum heat insulation material, porous heat insulation material or heat-reflecting heat-insulating material.
As shown in Figure 2, on lithium battery module 2 and lower cover 5, there is electric contact, electromagnetic induction coil 4 has sensed high-frequency oscillation signal, by rectification module rectification, arrive again Voltage Regulator Module, by wireless charging administrative unit, be adjusted to suitable charging voltage, give lithium cell charging, when external wired charger charges, external wired main charger is connected to lower cover electric contact, current sample module samples has electric current to pass through to sampling resistor 9, at this moment closes wireless charging function, only with external charger, charges.When wireless charger filled after a period of time, electromagnetic induction coil 4 will generate heat, temperature sensor 8 on heat shield 6 just has the variation of resistance, by temperature sampling module, sends the variation of resistance to wireless charging administrative unit, and wireless charging administrative unit will be controlled charging process.
Give this lithium cell charging; on electromagnetic induction coil 4, produce a large amount of heats; by the protection of heat shield 6; can completely cut off the heat that electromagnetic induction coil 4 produces; guarantee that battery temperature can not become very high, increased the life-span of battery, eliminated potential safety hazard; simultaneously screen 7 can intercept the interference that radio magnetic wave causes battery core and electronic product, very practical.
Except above preferred embodiment, the utility model also has other execution mode, those skilled in the art can make various changes and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
