Description

A kind of mobile phone standby power supply device

Technical field

The utility model relates to a kind of implement for mobile phone, is specifically related to a kind of mobile phone standby power supply device, makes mobile phone not exclusively depend on mains supply.

Background technology

Mobile phone has been and human lives's one of the most closely-related important apparatus at present.The mobile phone of existing market sale by structural division is: parts such as main frame (bare machine), power supply and SM (or C) card are formed.Wherein mostly cellular phone power supplies is lithium ion battery, it is little that this lithium ion battery has a volume, advantages such as discharge is long, but also cost an arm and a leg, repeatedly damage easy to charge, and rely on shortcomings such as commercial power charged, especially when situation such as large-area power-cuts occurs, go out operation or emergency have little time charging, mobile phone can't be got in touch with the external world because of there not being simple substitute electric power, realizes the permissible call of information communication.

Occurred adopting solar cell and individual handset to save the application example of AAA battery in the market as new cell-phone battery mode with common commercially available one, yet this employing one batteries is made the hardware and software aspect as the application need of stand-by power supply to the circuit structure of mobile phone itself and is changed accordingly, and the operating voltage of general mobile phone is more than the 3v, can't guarantee the stability of mobile phone electricity consumption.

Directly use No. 7 (AAA) batteries also to be packaged into the simple and easy standby or substitute electric power of reference power supply module, make it to obtain more convenient to usely not appear in the newspapers as yet as mobile phone.

The utility model content

The utility model provides a kind of mobile phone standby power supply device, and type of service scope that can the extended mobile phone battery is guaranteed the normal use of mobile phone when situations such as large-area power-cuts, open-air non-transformer operation or emergency have little time to charge.

The technical solution of the utility model is as described below:

This mobile phone standby power supply device comprises reserve battery, stand-by battery box and stand-by power supply output interface; Described reserve battery is at least two joints No. 6 or No. 7 dry cells, and dry cell is arranged in the stand-by battery box with the circuit series system; Described stand-by battery box adopts the combination of engineering plastics dry cell porous magazine-type; The standard input interface of described stand-by power supply output interface and cell-phone charging is complementary.

Above-mentioned stand-by power supply output interface is the reference power supply plug of being drawn by the stand-by battery box top.

Also be provided with reference power supply plug screens holddown groove on the panel of above-mentioned stand-by battery box outside, when not using this stand-by power supply, its reference power supply plug arrangement can be placed in the screens holddown groove.

Above-mentioned stand-by battery box bottom also is provided with the USB interface charger matched with mobile phones universal.

Above-mentioned reserve battery can be a rechargeable battery, utilizes above-mentioned USB interface also can charge to dry cell batteries under the situation of mains supply having like this.

Above-mentioned stand-by battery box can be made standard, and promptly thickness is 15～17 millimeters, and its porous magazine-type combination is that 3 diameters are 11 ± 5 millimeters, No. 7 AAA battery installing holes of length 44 ± 5 mm lengths.

The utlity model has following advantage:

1, can be used as the standard fitting of mobile phone, do not need any adjustment is done in mobile phone itself design, but thereby have the universality mass production, production cost is lower;

2, adopt as easy as rolling off a log purchase in market and cheap AAA battery, provide the replacement and the application of uninterrupted battery, can improve the effective replacement and the utilance of cellular phone power supplies to mobile phone, can one-object-many-purposes, solve the problems such as emergent and inconvenience of people when often using;

3, easy and simple to handle, and the panel of stand-by battery box outside is provided with reference power supply plug screens holddown groove, Stability Analysis of Structures, safe and reliable, save the space, profile is succinct.

Fig. 2 is the utility model structural representation (Fig. 1 left view is analysed and observe);

Fig. 3 is an AAA battery fixed head schematic diagram (Fig. 1 left view).

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

Referring to Fig. 1, Fig. 2 and Fig. 3, stand-by battery box of the present utility model adopts the combination of engineering plastics dry cell porous magazine-type, consider battery case volume and loading space, the preferred standby magazine-type battery case 1 that loads No. 7 batteries, the thickness of magazine-type battery case 1 is 15～17 millimeters, being provided with three diameters in magazine-type battery case 1 is 11 millimeters, No. 7 AAA battery installing holes of length 44 ± 5 mm lengths, No. 7 batteries 2 of three joints are arranged side by side according to the circuit series system, voltage after the series connection is 4.5V, and electric current is 600～1500mA, can ensure the long-time standby of mobile phone when cell voltage is reduced to 3V and conversation continuously.The top extracting power supply cord 7 of magazine-type battery case 1, the output of power line 7 are the reference power supply plug 3 that can be connected with mobile phone, as the power output interface of magazine-type battery case 1, are complementary with the power input interface of mobile phone.Be provided with the USB interface 4 charger matched with mobile phones universal in the bottom of magazine-type battery case 1, under situation with good conditionsi, can be by corresponding connecting line to No. 7 batteries 2 in the magazine-type battery case 1 charge (No. 7 batteries should selecting rechargeable type for use this moment certainly).
