Background technology

At present, various digital electronic goods such as mobile phone, Mp3, digital camera are widely used, and bring great convenience for people's life, have improved quality of the life greatly, are all to need electricity could use but these electronic products have a common ground.Therefore, the thing of just having become a trouble how for numerous digital product chargings at one's side is especially when going out.Best way is the charging inlet of all digital products to be made unified, charging is also made unifiedly again, so just can charge to all digital product with a charger.Yet make unification to the charging inlet of digital product and charger is an extremely large order, at least to not realizing also that so far the charging inlet of most of digital product still is different.In addition, even if really realized unification, carried a charger, do not had electric place but often also can run into, as the field, various situations such as perhaps power supply is improper cause not have electricity to fill; And charging neither can be finished soon.These situations all can influence the use of digital product, even delay people's thing.

The utility model content

The technical problems to be solved in the utility model provides a kind of simple in structure, convenient and practical, portable portable power source with the output of multiple charging modes and multiple power supply.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of portable portable power source, comprise housing, it is characterized in that: housing is provided with charging input interface, USB interface, power output interface, output control and reset switch, and this switch is used to control output of 5V voltage and homing action; Be provided with 16-24V AC/DC charging input and power output circuit in the housing, 16-24V AC/DC charging input and power output circuit connect 16.6V/1.0A constant-current constant-voltage charging circuit and 16-24V DC booster circuit respectively; Detect control circuit 16.6V/1.0A the constant-current constant-voltage charging circuit connects single-chip microcomputer, it is to be used to detect overcurrent, overvoltage, overheated and the detection control circuit of situations such as no-output is arranged that single-chip microcomputer detects control circuit, can play the automatic function of protecting; Single-chip microcomputer detects control circuit and connects 16-24V DC booster circuit, 5V/2A USB output circuit and battery high accuracy protective circuit respectively; battery high accuracy protective circuit is controlled the charge and discharge process automatically; it connects four explosion-proof polymer batteries, and the High Output Current of battery reaches 3A.

Further; on housing, also be provided with the sun-generated electric power charging inlet; be provided with the rechargeable solar battery interface circuit in the housing; can adopt solar cell in the open air is its charging; the rechargeable solar battery interface circuit connects battery high accuracy protective circuit, and battery high accuracy protective circuit detects control circuit with single-chip microcomputer and is connected.

Further, on housing, also be provided with output voltage and energy content of battery display screen, can show the electric weight of battery and the numerical value of output voltage automatically; Output voltage and energy content of battery display screen are by battery electric quantity charactron display circuit and the control of 16-24V output charactron display circuit, and battery electric quantity charactron display circuit and 16-24V output charactron display circuit connect control single chip computer and detect control circuit.

The utlity model has following function: the first, voltage is protected when being lower than 12V and being higher than 16.6V automatically; The second, make charging input and power output interface have the charging priority function; Three, charging current is protected automatically greater than 3A; Automatically protect when four, charging is overheated.Also have 16-24V output, output line control, digital display voltage value in addition; 5.2V output, by key control, 15S closes when detecting no current automatically; Energy content of battery percentage shows 0-100% (12V-16.6V); Stand-by power consumption is less than 3mA etc.

The utility model can be charged in advance under the situation that charge condition and enough time are arranged, just can use the utility model after the electric weight of digital product uses up is its power supply, this product is equipped with two kinds of power output interfaces, therefore be applicable to multiple digital product, the utility model can also connect rechargeable solar battery in addition, can there be the place of electricity to use in the open air, therefore extremely convenient and practical.
