Further, described power storage module is provided with protection circuit, and this protection circuit plays over-pressed, under-voltage and short-circuit protection.
Further, described charging management chip is ASC8513 single lithium battery charging management chip.
Further, described battery is No. 5 accumulator.
Further, described outfan is provided with USB interface.
Further, described booster circuit is DC-DC booster circuit, and its output voltage is 5V.
The beneficial effects of the utility model are：
1. provide a kind of continuation of the journey pattern, when the power storage module electricity of portable power source is finished, and input power is not done Method finds the power supply that can supply from nearby, and now power supervisor can automatically switch to motor generator to generate electricity, by No. five electricity Electricity priming motor generator in pond is generated electricity, and now MCU controller can control the rotating speed of motor generator, allows motor to send out Motor keeps uniform rotating speed to generate electricity.In No.5 cell not enough power supply, normal condition motor generator can therefore and rotating speed slows down, But because the control by MCU controller is delivered to power storage module so that motor generator can smoothly generate electricity.Power storage module is passed through Boost module electric current is changed after out-put supply.Enable mobile phone quick charge.
2., with respect to the like product on market, such portable power source increases the charging current of itself, shortens movement Power supply required waiting time when charging to itself；Optimize booster circuit, USB port has the energy of output 2A electric current Power, output voltage is steady；Improve the safety of circuit, increased excessively stream, overvoltage, the protection circuit such as under-voltage;And have automatically Identification load and the function of shutdown.
Brief description
Accompanying drawing described herein is used for providing further understanding to of the present utility model, constitutes the part of the application, Do not constitute to improper restriction of the present utility model, in the accompanying drawings：
The system principle schematic diagram of the portable power source with generating function that Fig. 1 provides for this utility model；
The circuit diagram of the power management chip that Fig. 2 provides for this utility model；
The circuit diagram of the booster circuit that Fig. 3 provides for this utility model；
The circuit diagram of the current foldback circuit that Fig. 4 provides for this utility model.
Specific embodiment
To describe this utility model below in conjunction with accompanying drawing and specific embodiment in detail, here signal of the present utility model Property embodiment and explanation be used for explaining this utility model, but be not intended as to restriction of the present utility model.
With reference to Fig. 1, a kind of portable power source with generating function, including MCU controller 1, booster circuit 3, current protection electricity Road 4, outfan 2, charging management chip 6, portable power source state display lamp 9 and power storage module 8, described MCU controller 1 respectively with Booster circuit 3, current protecting circuit 4, charging management chip 6 and portable power source state display lamp 9 connect, charging management chip 6 And portable power source state display lamp 9 connects power storage module 8, booster circuit 3 is connected respectively with outfan 2 and over-current protecting unit 4 Connect, described MCU controller 1 is connected with power supervisor 5, power supervisor 5 connects power end 13 by switch 10 1 tunnel, separately One tunnel connects battery 11, and described power end 13 connects power storage module 8, and described battery 11 connects electric power storage mould by motor generator 12 Block 8.
Described power storage module 8 is provided with protection circuit 7,7 overvoltages of this protection circuit, under-voltage and short-circuit protection.
With reference to Fig. 2, described charging management chip 6 is ASC8513 single lithium battery charging management chip.It adopts peak value electricity The stream control model of mould and the technology of synchronous rectification, can be greatly enhanced charge efficiency it is adaptable to the occasion of quick charge, fill Electric current is up to 2A.ASC8513 is integrated with the functions such as overheat protector, short-circuit protection, and 2 LED indicate respectively battery charging shape State and fill full state.
With reference to Fig. 3, described booster circuit 3 is DC-DC booster circuit, and its output voltage is 5V.Portable power source itself lithium electricity The nominal voltage of pond group is 3.7V it is therefore desirable to just can be filled to outside portable set with this cell voltage is raised to 5V Electricity.To complete the function of boost module using ME2109 boost chip in system.ME2109 by reference voltage source, oscillating circuit, The CMOS boost DC-DC controller of the compositions such as error amplifier, phase compensating circuit and PWM/PFM control switching circuit.Pass through External NMOS, can accomplish the effect that delivery efficiency is higher, output current is bigger.
With reference to Fig. 4, in order to improve the safety of portable power source use, the system design overcurrent protection of output port, such as More than 2 A, booster circuit 3 will no longer work fruit output port electric current, after single-chip microcomputer detects excessively stream simultaneously, turn off delivery outlet Negative terminal and the connection on ground, such portable power source would not powering load.
This utility model additionally provides a kind of continuation of the journey pattern, when power storage module 8 electricity of portable power source is finished, and inputs Power supply has no idea to find the power supply that can supply from nearby, and now power supervisor 5 can automatically switch to motor generator 12 Generate electricity, generated electricity by the electricity priming motor generator 12 in No.5 cell, now MCU controller 1 can control motor to generate electricity The rotating speed of machine 12, allows motor generator 12 keep uniform rotating speed to generate electricity.In No.5 cell not enough power supply, normal condition motor is sent out Motor 12 can therefore and rotating speed slows down, but because the control by MCU controller 1 is so that motor generator 12 can smoothly generate electricity It is delivered to power storage module 8.Power storage module 8 by boost module 3, electric current is changed after out-put supply.Make mobile phone or move eventually End can quick charge.
The technical scheme above this utility model embodiment being provided is described in detail, used herein specifically Embodiment is set forth to the principle of this utility model embodiment and embodiment, and the explanation of above example is only applicable to Help understand the principle of this utility model embodiment；Simultaneously for one of ordinary skill in the art, real according to this utility model Apply example, specific embodiment and range of application all will change, in sum, this specification content should not be understood It is to restriction of the present utility model.
