Abstract

The utility model discloses a multifunctional charger; wherein, the front surface of the charger is provided with a lithium battery clamping seat; the back surface of the charger is provided with a plug and two clamping seats for 5# batteries; the side surface of the charger is provided with a USB interface. The charger can simultaneously charge a chargeable battery of 5#, a mobile phone battery and a mobile phone arranged inside the charger when being connected with a commercial power. The inside of the charger is also provided with a DC converting circuit; under the situation without the commercial power, the DC converting circuit can carry out switching on a voltage outputted by the 5# batteries and output the voltage by the USB interface. Compared with prior art, the multifunctional charger is delicate and small, is conveniently carried and is very convenient to carry out charging on the mobile phone battery by adopting a 5# AA battery.

Description

Multifunctional charger

Technical field:

The utility model relates to a kind of charger, particularly a kind of can by common batteries to battery of mobile phone directly fill and the seat charging the multi-function emergency charger.

Background technology:

Mobile phone is as communication tool commonly used, its battery is general, and what adopt is the specialized lithium ion battery, tourism in the open air, and go on business or in road in the other places, if run into powering-off state, then can't carry out replenishing immediately, therefore need carry charger or reserve battery, and generally, in the open air or go out the way in, there is not civil power, even it is there is charger also can not charge like this, therefore very inconvenient.

Summary of the invention:

For addressing the above problem, the purpose of this utility model is to provide a kind of multi-function emergency charger, and this charger can be that battery of mobile phone charges immediately by common No. 5 AA batteries when running into powering-off state.

For achieving the above object, the utility model mainly adopts following technical scheme:

A kind of multifunctional charger, wherein said charger front is provided with the lithium battery deck, the back side is provided with plug and two No. 5 battery decks, the side is provided with USB interface, described charger inside also is provided with DC converting circuit, this DC converting circuit can be changed the voltage of No. 5 battery outputs, and through USB interface output.

Described plug is a movable plug, can directly be electrically connected with the city by this plug, and process lithium battery deck is a lithium cell charging.

When using the civil power input, charger can be output as mobile phone or other power electronic equipment through USB interface, can fill No. 5 batteries for it is built-in simultaneously and charge.

The utility model is changed the voltage of common No. 5 batteries output by inner DC converting circuit, and can directly fill for battery of mobile phone by USB interface output, can directly be electrically connected by the plug on the mobile phone in addition with outside city, realization is filled the seat of battery of mobile phone, the utility model is smart refined small and exquisite, easy to carry, No. 5 AA batteries of employing can charge for battery of mobile phone under different situations.

Description of drawings:

Fig. 1 is the utility model schematic perspective view.

Fig. 2 is the utility model internal structure schematic diagram.

Fig. 3 is the utility model front schematic view.

Embodiment:

Below in conjunction with the drawings and specific embodiments the utility model is described in further details.

As shown in Figure 1, a kind of multifunctional charger, the back side of wherein said charger be provided with plug 2 and and battery cover 3, described plug 2 is a movable plug, and between battery cover 3, these plug 2 movable digging with outside city are electrically connected, and also are provided with a usb 1 on the described charger case, and this interface is connected with the charger internal circuit.

As shown in Figure 2, described battery cover lower end is a battery deck 4, this battery deck 4 is special-purpose No. 5 AA battery decks, this battery deck 4 can be put into the chargeable No. 5 AA batteries of 2 joints, when connection was commercial power charged, the charger internal circuit charged for chargeable No. 5 AA batteries in the deck 4 simultaneously. and this deck 4 is connected by the circuit of lead with charger inside, and the charger internal circuit is changed the voltage of No. 5 batteries, enable to realize charging to battery of mobile phone by usb 1 output.

As shown in Figure 3, described charger front is that a seat fills deck, it is battery of mobile phone deck 5, this deck 5 is connected with charger internal electric source change-over circuit by Metallic card, during charging, can directly battery of mobile phone be packed in this deck 4, it is connected with charging circuit, and be electrically connected with the city by plug 2, it is battery charge that the transforming circuit by charger inside converts thereof into direct current.

And in addition, when not having the situation of civil power, then can adopt No. 5 common AA batteries, at first battery is installed in the battery deck 4, and fix by battery cover 3, then mobile phone is connected by the USB connecting line with the usb 1 of charger, thereby realizes mobile phone is directly filled.

Also be provided with two indicator lights on the described charger housing, can show the charged state that battery of mobile phone is current by this indicator light.

Inner DC converting circuit of the utility model and interchange are changeed DC circuit and are basic circuit, implementation procedure is simple and convenient, more than a kind of multifunctional charger provided by the utility model is described in detail, used specific case herein principle of the present utility model and execution mode are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
