Description
Technical field
The present invention relates to portable power source technical field, more particularly to a kind of portable power source of controllable output current size.
Background technology
With the development of electronic product, the need for simplifying trip to meet that people are daily, rechargeable battery is in each side
Face is applied, and particularly in light mobile electronic product field, this just has a demand charged to this kind of product battery, together
When, the small portable chemical conversion of consumption electronic product is the development trend of main flow.This requires that product volume weight in itself needs not
Disconnected reduction.And the portable mobile termianl such as another aspect mobile phone is in use, for energy demand but continuous
Increase, therefore, the necessaries of portable power source cost boost charge when outgoing.
During for electronic terminal charges such as mobile phones, cross conference due to charging current causes to be electrically charged product present user
Product heating is serious, can so influence the experience of user, and because heating even can trigger security incident.
The content of the invention
The present invention is in view of the existing deficiencies of the prior art, there is provided a kind of portable power source of controllable output current size, its
Can with the size of the manual controlled output electric current of the use feeling of user, effectively solves the problems, such as to be electrically charged sub- product generate heat it is serious,
Improve the experience of user, it is to avoid occur because of the security incident that heating causes.
To achieve the above object, the present invention is using following technical scheme：
A kind of portable power source of controllable output current size, including shell, the battery pack in shell and exportable
The charging circuit of different constant currents, the charging circuit includes voltage transformation and current control unit, MCU control unit and letter
Number handover module, the battery pack is connected with voltage transformation and current control unit, the voltage transformation and current control unit
It is connected with MCU control unit, the signal handover module includes that a switching switch and multiple current limlitings with different resistances are set
Resistance, the switching switch switches between multiple current limlitings set resistance, and the MCU control unit is connected with switching switch, institute
State shell and be provided with power output interface and control button, the power output interface connects with voltage transformation and current control unit
Connect, the control button is connected with MCU control unit communication, input signal control of the MCU control unit according to control button
System switching switch is switched to corresponding current limliting and sets resistance, and the voltage transformation and current control unit are set according to corresponding current limliting
Correspondingly sized electric current output is arrived power output interface by the feedback signal of resistance.
Used as a kind of preferred scheme, it is two that the current limliting sets resistance, including the first current limliting sets resistance and the second limit
Stream sets resistance, and first current limliting sets the resistance of the resistance less than the second current limliting setting resistance of resistance.
The present invention compared with prior art, with advantages below and advantage, specifically, is provided with MCU in this portable power source
Control unit and signal handover module, the signal handover module include a switching switch and multiple current limlitings with different resistances
Resistance is set, and the switching switch switches between multiple current limlitings set resistance, and the MCU control unit connects with switching switch
Connect, the control button is connected with MCU control unit communication, input signal control of the MCU control unit according to control button
System switching switch is switched to corresponding current limliting and sets resistance, and the voltage transformation and current control unit are set according to corresponding current limliting
The size of the feedback signal controlled output electric current of resistance, so when electron product charges, as long as user feels to be electrically charged son
Product heating is serious, and just can directly press control button makes the output current of portable power source diminish, and effectively solves to be electrically charged sub- product
The serious problem of product heating, improves the experience of user, it is to avoid occur because of the security incident that heating causes；On the other hand work as and use
When family feels that being electrically charged sub- product charges slow, just pressable control button makes the output current of portable power source become big, portable power source
It is quick to reduce charging duration to sub- product charging is electrically charged, charge efficiency is improved, it is user-friendly to.
It is the specific purposes and function that more clearly illustrate architectural feature of the invention, technological means and its reached, under
Face is described in further detail with specific embodiment with reference to accompanying drawing to the present invention：
Brief description of the drawings
Fig. 1 is the structural representation of embodiments of the present invention.
Accompanying drawing identifier declaration：
1- battery packs, 2- voltage transformations and current control unit, 3-MCU control units, 4- signal handover modules, 41- cut
Switch is changed, the current limlitings of 42- first set resistance, and the current limlitings of 43- second set resistance, 5- power output interfaces, 6- control buttons.
