Description

A kind of charger with portable power source function
Technical field
The utility model relates to charging device technical field, is specifically related to a kind of charger with portable power source function, is applicable to charge to rechargeable battery and external electric equipment without under the environment of civil power in the wild.
Background technology
After current charger needs external power supply, just charge to rechargeable battery or external electric equipment by charger conversion electric power, therefore, generally be applicable to indoor or have the place of power supply, and portable power source can not realize charging to rechargeable battery, this just causes in the wild without inconvenient to rechargeable battery or external electric equipment charging under the environment of civil power.
Utility model content
Technical problem to be solved in the utility model provides a kind of charger with portable power source function for above-mentioned the deficiencies in the prior art, the purpose of this utility model is on charger, increase portable power source function, realizes charging to rechargeable battery or external electric equipment without under the environment of civil power in the wild.
In order to solve the problem, adopted technical scheme is:
The utility model provides a kind of charger with portable power source function, comprise the reduction voltage circuit be connected with DC supply input, the charge circuit be connected with described reduction voltage circuit, the internal cell be connected with described charge circuit and external charge battery case, be connected with described reduction voltage circuit and charge circuit, for the charging control circuit controlled charging process, the booster circuit be connected with charging control circuit and internal cell and boost control circuit, described booster circuit and boost control circuit connect rechargeable battery groove and USB output, reduction voltage circuit connects described USB output.
The beneficial effects of the utility model are:
What the utility model provided has the charger of portable power source function by arranging reduction voltage circuit, charge circuit, charging control circuit, booster circuit and boost control circuit in charger, realizes charging to rechargeable battery or external electric equipment without under the environment of civil power in the wild.
Accompanying drawing explanation
Accompanying drawing is the system configuration schematic diagram with the charger of portable power source function of the present utility model.
Embodiment
Specifically illustrate execution mode of the present utility model below in conjunction with accompanying drawing, accompanying drawing is only for reference and use is described, does not form the restriction to the utility model scope of patent protection.
As shown in drawings, the present embodiment relates to a kind of charger with portable power source function, comprise the reduction voltage circuit be connected with DC supply input, the charge circuit be connected with described reduction voltage circuit, the internal cell be connected with described charge circuit and external charge battery case, be connected with described reduction voltage circuit and charge circuit, for the charging control circuit (MCU) controlled charging process, the booster circuit be connected with charging control circuit and internal cell and boost control circuit, described booster circuit and boost control circuit connect rechargeable battery groove and USB output, reduction voltage circuit connects described USB output.
In the present embodiment, described DC supply input connects 12V direct-current input power supplying.
In the present embodiment, the described charger with portable power source function both directly connects USB output by reduction voltage circuit directly provides DC charging function, charge circuit can be passed through again, internal cell, after charging accumulate, pass through booster circuit again, USB output realizes charging to external electric equipment, charge circuit can also be passed through, rechargeable battery groove, realize charging to rechargeable battery, therefore, the charger of portable power source function that what the present embodiment provided have has multi-charging functions, and there is portable power source function simultaneously, be applicable to indoor and the field environment without civil power simultaneously, applicability is wider.
Above-described embodiment is the utility model preferably execution mode; but execution mode of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection range of the present utility model.
