Description

A kind of multifunctional charger
Technical field
The utility model relates to charger technologies field.
Background technology
Along with popularizing of camera/camcorder/digital product, charger is absolutely necessary accessory, generally include charging and straight-charging type, charging generally comprises mains plug, cell containing cavity and built-in charging circuit board, by voltage stabilizing circuit and reduction voltage circuit by after civil power step-down for being placed on rechargeable battery (as the lithium battery) charging in cell containing cavity.Straight-charging type generally also comprises mains plug and built-in charging circuit board, does not just have cell containing cavity, is directly exported the voltage of 5V by USB standard interface, connects charging device charge by USB charging wire.Existing various product producer is all centered by oneself on the design and production of charger, and what compatible environmental protection and Multifunctional design did is inadequate, causes consumer resources to waste.
Utility model content
For this reason, technical problem to be solved in the utility model is: provide one environmental protection more, compatible better multifunctional charger.
So, the utility model provides following technical scheme: a kind of multifunctional charger, comprise attaching plug, charger case, cell containing cavity and the circuit board be built in charger case, described charger case is provided with USB standard output interface and MICRO USB input interface, described circuit board comprises switch power voltage-stabilizing circuit, reduction voltage circuit and booster circuit, described switch power voltage-stabilizing circuit one tunnel connects described USB standard output interface through reduction voltage circuit, the both positive and negative polarity that another road is first electrically connected cell containing cavity connects described reduction voltage circuit again, described MICROUSB input interface is connected to the both positive and negative polarity of described cell containing cavity through described booster circuit.
Preferably, described charger case is also provided with charging indicator light.
The beneficial effects of the utility model are: charger of the present utility model, overcome the shortcoming of the single poor compatibility of existing charger function, by arranging USB standard output interface and MICRO USB input interface, circuit board arranges switch power voltage-stabilizing circuit, reduction voltage circuit and booster circuit, on the one hand compatible directly filling fills two kinds of charging modes with seat, can realize portable power source function by the combination of battery and charger on the other hand, the battery electric quantity that can realize plurality of devices is shared.
Accompanying drawing explanation
Fig. 1 to Fig. 3 is the shape assumption diagram of embodiment multifunctional charger.
Fig. 4 is embodiment charger circuit schematic diagram.
Embodiment
Below, with specific embodiments and the drawings is described in detail the utility model.
A kind of multifunctional charger, its shape assumption diagram is referring to accompanying drawing 1 to accompanying drawing 3, comprise attaching plug 1, charger case 2, cell containing cavity 3, USB standard output interface 4, MICROUSB input interface 5, charging indicator light 6 and the circuit board (not shown) be built in charger case 2, cell containing cavity 3 is for placing lithium battery, attaching plug is for connecting mains supply, MICRO USB input interface 5 can connect the USB power source output interface of other equipment by USB data line, USB standard output interface 4 is for exporting the normal voltage of 5V to charging equipment.
The circuit theory diagrams of the present embodiment are referring to accompanying drawing 4, comprise switch power voltage-stabilizing circuit, reduction voltage circuit and booster circuit, switch power voltage-stabilizing circuit one tunnel connects USB standard output interface 4 through reduction voltage circuit, the both positive and negative polarity that another road is first electrically connected cell containing cavity 3 connects reduction voltage circuit again, and MICRO USB input interface 5 is connected to the both positive and negative polarity of cell containing cavity 3 through booster circuit.
Its circuit working principle is: civil power exports 8.4V voltage of voltage regulation through switch power voltage-stabilizing circuit plugged by the attaching plug of charger, one road reduction voltage circuit connects USB standard output interface 4, export 5V by USB standard output interface 4 to charge to mobile phone or digital product, the both positive and negative polarity that another road is connected to cell containing cavity 3 can realize charging to rechargeable battery, during charging, charging indicator light 6 sends out a warning, and is full of electric charging indicator light 6 and gives a green light.When not having civil power to input, 5V output voltage is got from the power supply output of computer USB seat or motor vehicle by USB data line, input through MICRO USB input interface, the both positive and negative polarity being connected to cell containing cavity 3 again after booster circuit boosting is 8V voltage charges the battery, while charging, can realize charging to mobile phone or digital product through reduction voltage circuit and USB standard output interface 4.
The advantage of the charger of the present embodiment is: the USB5V of 1, compatible alternating current 100-250V and world standard comes for battery charging; The USB 5V converting world standard when 2, achieving alternating current 100-250V to is the charging of various digital equipment; 3, can be realized battery discharge by the combination of battery and charger, namely portable power source function, the electricity that can realize plurality of devices is shared; 4, comprehensive above 3 points, achieve multi-functional in one, convenient, environmental protection.
Introduce the scene that the present embodiment may be used below, when user's out on tours, only can be with a charger, realize multiple equipment charges such as video camera, mobile phone, panel computers, when video camera battery is finished, the battery of mobile phone can be taken out and be placed in charger, by the USB standard output Interface realization of charger, video camera be charged, now, battery of mobile phone and charger combination are equivalent to a portable power source.Otherwise, when battery of mobile phone does not have electricity, by loading the charging that video camera battery can realize mobile phone in charger.
Another scene is: have a lot of people to complain that camera battery is easy to bad; buy half a year just to have gone bad; its reason is; battery is that chemical raw material is made; lithium electricity under normal circumstances; can circulate more than 1000 times. camera battery just has no idea to discharge except taking; can also to be realized the tele-release of camera battery every a period of time enter in mobile phone by the multifunctional charger of the present embodiment; then be full of; like this while many portable power sources; ensure that the circulation of camera battery, effectively protect battery.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
