Fig. 1 is the utility model structural representation;
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described:
The present embodiment comprises upper shell 1, lower house 2, and metal heating board 3, discharges and recharges temperature control module 4 and lighium polymer electricity 5.On upper shell with the driving switch 4-2 of a third gear, for controlling output charge function and the warm hand function of portable power source.Metal heating board is fixed on lower house by screw and buckle, on metal heating board, be compounded with a low-voltage small-power heating film 3-1 and a temperature sensor 3-2, the lead-in wire of temperature sensor and the lead-in wire of heating film through lower house be connected to discharge and recharge with temperature control module on.Between metal heating board and lower house, be filled with heat-barrier material, heat insulation between metal heating board and lower house.Discharge and recharge with temperature control module on have complete charging and discharging lithium battery circuit, and have temperature control circuit for controlling the heating temp of heating film.Discharge and recharge with temperature control module on have female mouthful of 4-4 of standard USB A type for 5V power supply is outwards provided, also have a micro USB interface 4-1 to charge to portable power source for external USB 5V power supply.Discharge and recharge with temperature control module on be also provided with a red greenish-yellow three-color LED light, can be by different operating state change work colors.Lithium polymer battery is fixed between upper shell and lower house, has battery protecting plate above, is connected to and is discharged and recharged and temperature control module, for providing electric energy to system by lead-in wire.
Upper shell and lower house adopt the material injection mo(u)lding of plastic material.Metal heating board adopts the thermal conductive metallic material of aluminium alloy to make, and can effectively the heat of low-voltage small-power heating film be evenly transmitted to whole metal heating board.
The low-voltage small-power heating film that metal heating board covers by inner side generates heat, and under the control that discharges and recharges temperature control module and temperature sensor, keeps the surface temperature of metal heating board, enables when work, and long term maintenance is in the comfortable temperature of human body.
On upper shell, there is a three-color LED indicator light 4-3, can be red, green according to different use state demonstrations, yellow three kinds of different colors.Play in off position indicator light to extinguish.The shown in red breath light state of indicator light under warm hand state, when battery electric quantity is not enough, the shown in red blink states of indicator light.Insert USB interface, during to built-in lithium cell charging, be shown as yellow breath light state, after having charged, be shown as yellow Chang Liang.Be switched to after supplying power for outside pattern, the shown in green Chang Liang of indicator light, when inserting USB interface to outside digital product power supply, indicator light is transformed into green breath light from green Chang Liang, when electric weight is not enough, the shown in green flicker of indicator light.Under supplying power for outside pattern, run into output current when excessive, indicator light is shown in red, and indication output current is excessive, and indicating lamp display mode is: fast blink three times, pauses one second, repeatedly repetition.
Discharge and recharge temperature control module, adopted microcontroller protection and two kinds of modes of standard cell baffle, battery is carried out to dual overcurrent protection and dual anti-under-voltage protection, prevent lithium polymer battery overdischarge.Wherein microcontroller detects in real time to the capacity of lithium polymer battery; When lithium polymer battery capacity is lower, by the mode of indicator light flicker, remind, reminding user charges in time; When lithium polymer battery capacity is zero, close the electric weight output of lithium polymer battery, prevent that lithium polymer battery from damaging because of overdischarge.
Discharge and recharge temperature control module, when lithium polymer battery is charged, take three stage charge modes.When lithium polymer battery voltage is during lower than 3V, discharge and recharge temperature control module, with little electric current, lithium polymer battery is carried out to precharge.When lithium polymer battery voltage surpasses 3V, discharge and recharge temperature control module and adopt constant current mode to charge to lithium polymer battery.When lithium polymer battery voltage approaches 4.2V voltage, charging current reduces gradually, enters constant voltage charge pattern.When charging current is reduced to charging end threshold value, charge cycle finishes.
The portable power source of warm hand function is respectively equipped with standard USB charging input port and USB power output.USB charging input port adopts the micro USB interface of standard as interface, can the general micro USB charging wire of match-on criterion.USB power output adopts the female mouth of the USB A type of standard as interface, equally can the general micro USB charging wire of match-on criterion.The portable power source of warm hand function only needs the micro USB charging wire of a standard universal just can charge and power supply output.
