Embodiment

As shown in Figure 1 to Figure 3, a kind of portable portable power source is characterized in that comprising external power source interface 1, solar battery group 2, hand power unit 3, power change-over switch and voltage indicating circuit 4, lithium cell charging circuit 5, poly-lithium battery and protective circuit 6 thereof and booster circuit and output interface 9; Described solar battery group 2 is made of with voltage stabilizing and protective circuit 202 thin-film solar cells 201 that (thin-film solar cells 201 becomes electric energy with solar energy converting, again by after voltage stabilizing and protective circuit 202 voltage stabilizings stable electric energy being exported), described hand power unit 3 is made of miniature hand-rail type generator 301 and rectification and protective circuit of voltage regulation 302 and (can charges by miniature hand-rail type generator 301 when overcast and rainy, the user only need rotate the handle (the label C among Fig. 2 and Fig. 3) of miniature hand-rail type generator 301 to drive miniature hand-rail type generator 301 generatings, again by the stable electric energy of output behind rectification and the protective circuit of voltage regulation 302 as shown in Figures 2 and 3); Described external power source interface 1, voltage stabilizing and protective circuit 202 are connected with power change-over switch and voltage indicating circuit 4 respectively with rectification and protective circuit of voltage regulation 302; Described power change-over switch and voltage indicating circuit 4 are connected with lithium cell charging circuit 5, and described lithium cell charging circuit 5 is connected with poly-lithium battery and protective circuit 6 thereof; During discharge, described poly-lithium battery and protective circuit 6 thereof are connected on booster circuit and the output interface 9 after by switch 7, and external loading is connected on booster circuit and the output interface 9 to obtain electric energy.Comprise that also battery electric quantity and charged state indicating circuit 8 are connected with booster circuit and output interface 9 with lithium cell charging circuit 5 respectively.Described thin-film solar cells 201 adopts collapsible setting, opens in use, and the time spent is not folded up.Described external power source interface 1 adopts the Mini USB interface.Described voltage stabilizing and protective circuit 202, rectification and protective circuit of voltage regulation 302 and 1 design of external power source interface are on a pcb board.

Pour in down a chimney for avoiding three-way power to use jointly, cause damage, power change-over switch and voltage indicating circuit 4 have used one three tunnel diverter switch to switch, and are voltage indicating circuit in parallel after the diverter switch, can indicate input voltage, avoid the situation of overvoltage to occur.Poly-lithium battery and protective circuit 6 thereof adopt the single-unit lithium polymer battery of 5000mAh, and charging IC adopts BQ24103, and protection IC adopts S-8211C.

Miniature hand-rail type generator 301 adopts 8W's, and handle adopts foldover design, can be integrated with shell usually, improves portable.Thin-film solar cells 201 adopts the collapsible design that is similar to the advertisement folding paper, directly draws back during use to get final product.In the sun, can play the effect that battery is partly shaded, avoid battery temperature too high.The time spent is not collapsible, reduces occupation space, has improved portability and effective area.

5V voltage is converted to the charging voltage of lithium battery through BQ24103.BQ24103 has good charging control flow, can guarantee the fail safe of charging.Lithium battery does not have memory effect, can charge at any time, can not influence its useful life.Therefore, there is no need disposable being full of, improved operability, battery charger is done can be interrupted in one's spare time fully to carry out.Owing to having in the battery electricity is arranged always in addition, under situation about being badly in need of,, just can use at once, and not influence operation as long as mobile phone or other power consumption equipment are connected to portable power source by data wire.

Standard USB interface is adopted in output, and the user only need use the data wire of its mobile phone just can charge to mobile phone, has guaranteed the convenience of using, and has reduced the quantity of accessory simultaneously, helps environmental protection.Because lithium battery voltage is 4.2V, and most of mobile phone needs the voltage about 5V, therefore need voltage be risen to 5.2V by DC-DC, output current is set to 600mA simultaneously.Most of mobile phones are for to use on the USB mouth, and the complete machine electric current is set to 500mA, so the output current of 600mA is enough fully, can reduce cost simultaneously.

Voltage indicating circuit adopts the mode of resistance+LED, and resistance is with LED series connection dividing potential drop, and LED just can light when voltage surpasses set point.Adopt red, green two LEDs to indicate as shown in Figure 2 label A place: when voltage does not all work the expression undertension during less than 4.5V; Green light is bright when voltage is near 5V, and expression voltage is normal; When voltage during greater than 6V red light also bright, expression voltage surpass, needs reduction hand power rotating speed.

Electric weight indication is used and is detected voltage method, and adopt 5 blue leds to represent as shown in Figure 2 label B place: 5 complete bright expression batteries are full of; 1 bright expression electric weight is low, needs charging.The electric weight indication is worked always in charging process; Under the state of non-charging, the electric weight indication is closed, and by beginning the button that discharges, at this moment can show battery electric quantity up to the user, if non-loaded, then closed electric weight and show after 15 seconds; When giving cell-phone charging, meeting is the electric weight of display power supply always.The electric weight indication can be played the effect of reminding the user in time to replenish electric power to portable power source.Can increase a highlighted LED in addition, play the effect of Emergency Light.

The above; it only is the preferable embodiment of the utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and inventive concept thereof, all should be encompassed within the protection range of the present utility model.
