Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of this utility model exchange input portable power source is elaborated.
Seeing accompanying drawing 1, exchange input portable power source includes that charging module 1 and portable power source module 2, charging module 1 and portable power source module 2 are integrated on one piece of circuit board.
Charging module 1 includes step-down rectifier unit 3 and voltage regulation unit 4, electric main rectification again after step-down rectifier module 3 blood pressure lowering, delivers to voltage regulation unit 4, exports 5V DC voltage.Being provided with USB outfan 5 on portable power source, the 5V DC voltage of voltage regulation unit 4 output is directly exported supply electronic equipment charging by a USB outfan 5.
Power module 2 includes lithium battery 6, main control unit 7, charhing unit 8 and boosting unit 9, charhing unit 8 and boosting unit 9 are connected to main control unit 7, the voltage regulation unit 4 of charging module 1 is connected with charhing unit 8 with lithium battery 6, and boosting unit 9 is connected to another USB outfan 5 of portable power source.At mobile electricity
LED also can be set on source, for illumination or information alert.
Seeing accompanying drawing 2,220V line voltage is transformed into the 5V voltage needed for portable power source by charging module.And this voltage can also charge the phone, and is exported by USB1.
See accompanying drawing 3, main control unit application portable power source main control chip, coordinate to control the work of each several part circuit.
See accompanying drawing 4, in the circuit of charhing unit, realize constant voltage by U20 chip RZC4056 and linearly export.Resistance R22 left end is connected with the USB1 of charger, and right-hand member is connected with diode SS34 and is charged to portable power source by U20 chip.In the charge state, the 8th foot of U20 is high level, and the 7th foot is low level, and during charging complete, the 8th foot is end level, and the 7th foot is high level, the variation of these voltages, and main control unit can monitor.
Seeing accompanying drawing 5, boosting part is also controlled by main control unit chip, and when portable power source externally exports, the 3rd foot of U22 is controlled by main control chip, low transition become high level.When circuit is operated in charged state, the 3rd foot of U22 can have been at low level, and boosting output is turned off, and now charger can pass through the external output voltage of USB1.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
