Abstract
The utility model relates to a car attachs the electrical technology field, discloses an on -vehicle charger of movable, including input unit and USB output unit, still include lithium cell and power management unit, input unit is used for being connected to cigar lighters for automobiles, power management unit connects input unit, lithium cell and USB output unit work as when input unit connects cigar lighters for automobiles and has voltage input, power management unit is right give behind lithium batteries and the voltage -reducing by input unit the USB output unit power supply is worked as when input unit does not have voltage input, power management unit control the lithium cell is given after stepping up the USB output unit power supply. The utility model discloses when on -vehicle use, for lithium batteries, leave when on -vehicle, the lithium cell charges for the electronic product, makes the electronic product obtain the electric power that lasts.
Description
Technical field
This utility model relates to automobile auxiliary technical field of electricity, particularly relates to a kind of movable vehicle-mounted charging
Device.
Background technology
Automobile is more and more universal in the life of people, and a lot of people go out provisional capital and be unable to do without automobile, use onboard
Electronic product is also unavoidable.Automobile cigarette lighter is the interior main approach providing power supply of car.Pass through car
Carrying charger can be that electronic product is charged.
Existing onboard charger can only power taking from car, once vehicle stall, cigar lighter will not be provided that electricity
Can, cause charging process to be interrupted.
Utility model content
The purpose of this utility model is to solve the problems referred to above, it is provided that a kind of movable vehicle-mounted charger,
Lithium battery is installed in onboard charger, when cigar lighter is powered to lithium cell charging, cannot supply at cigar lighter
During electricity, lithium battery it is electronic product charging.
This utility model adopts the technical scheme that:
A kind of movable vehicle-mounted charger, including input block and USB output unit, is characterized in that, also
Including lithium battery and Power Management Unit, described input block is used for being connected to automobile cigarette lighter, described power supply
Administrative unit connects described input block, lithium battery and USB output unit, when described input block connects vapour
Car cigar lighter when having voltage to input, described Power Management Unit is to described lithium cell charging and by input block
Voltage step-down after give described USB output unit power, when described input block does not has voltage to input, institute
State after Power Management Unit controls the boosting of described lithium battery and power to described USB output unit.
Further, the capacity of described lithium battery is 3000-5000mAh.
Further, described Power Management Unit includes overcharge protection circuit.
The beneficial effects of the utility model are:
(1), during vehicle-mounted use, for lithium cell charging, when leaving vehicle-mounted, lithium battery is electronic product charging,
Electronic product is made to obtain lasting electric power;
(2) can carry with;
(3) when emergency communication, will not be limited by car situation.
Accompanying drawing explanation
Accompanying drawing 1 is structured flowchart of the present utility model.
Being numbered in accompanying drawing:
1. input block;2. lithium battery;
3. Power Management Unit;4.USB output unit;
5. charging module;6. supply module.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of this utility model movable vehicle-mounted charger is made specifically
Bright.
Seeing accompanying drawing 1, movable vehicle-mounted charger includes input block 1, lithium battery 2, power management list
Unit's 3 and USB output units 4, input block 1 is used for being connected to automobile cigarette lighter, and Power Management Unit 3 is even
Connect input block 1, lithium battery 2 and USB output unit 4, when input block 1 connects automobile cigarette lighter and has
During voltage input, lithium battery 2 is charged and by input block 1 by Power Management Unit 3 by charging module 5
Voltage step-down after give USB output unit 4 power, when input block 1 does not has voltage to input, power supply pipe
Reason unit 3 controls to power to USB output unit after lithium battery 2 is boosted by supply module 6.
In charging module 5 and supply module 6, be respectively provided with overcharge protection circuit, with protect lithium battery 2 and
Charged electronic equipment.The capacity of lithium battery 2 selects 3000-5000mAh, and this battery size is less, it is possible to
Meet the charge volume of most of electronic products, and the volume-diminished of onboard charger can be made.
The above is only preferred implementation of the present utility model, it is noted that for the art
Those of ordinary skill, on the premise of without departing from this utility model principle, it is also possible to make some improvement and profit
Decorations, these improvements and modifications also should be regarded as protection domain of the present utility model.
