Description

A kind of mutual charging circuit mutually charging between electronic equipment of realizing

Technical field

The utility model relates to charging circuit, more particularly, relates to a kind of mutual charging circuit mutually charging between electronic equipment of realizing.

Background technology

Along with the communication technology and economic fast development, portable electric appts has become the articles for daily use of staff indispensability as the main carriers in modern communication instrument and amusement equipment, for example smart mobile phone, panel computer, MP3 etc., traditional electronic equipment generally has following several charging modes: (at this, take mobile phone as example explanation)

1.: direct insertion charging modes, by special charger, utilizes civil power directly mobile phone to be charged.Its shortcoming is necessary civil power, otherwise can not charge.

2.: USB plug charging modes,, by USB socket, utilizes computer or 5 volts of DC power supply to charge to mobile phone.Its shortcoming is without computer or 5 volts of DC power supply in the situation that, can not charge to mobile phone.

3.: the precious charging modes that charges, utilize the accumulation of energy of external power source, mobile phone is charged.Its shortcoming is that charging treasured also must be by commercial power charged, and it is not too convenient to use; The precious volume that charges is larger, is not easy to carry.

For the people of frequent out of town trip, if in the situation that there is no civil power and portable power source, run into mobile phone and cannot normally use because of the not enough shutdown suddenly of electric weight, must cause very large inconvenience to contact with foreign countries.Although, also there is in the market solving the problem of mobile phone charging under this environment: the charger that utilizes the electric energy of dry cell to charge the phone, also have the hand-pressing charger that is converted to electric energy by mechanical energy to charge the phone, but, these chargers are owing to carrying inconvenience, and user can not carry at any time in order to prevent the shutdown of burst.Chinese Patent Application No. 200810033081.X discloses a kind of charge mobile phone and charging method thereof, its built-in hand-pressing charger, however this makes the volume of mobile phone and weight become very large, affects the portability of mobile phone; Chinese Patent Application No. 200910239636.0 discloses a kind of mobile phone that can charge to other mobile phones, need to use diode triode, the complicated circuits such as single-chip microcomputer, and need to manually press charge switch, cost is higher and inconvenient.

Summary of the invention

In order to solve the problems of the technologies described above, it is a kind of under specific environment that the utility model provides, and can realize the mutual charging circuit that can mutually charge between electronic equipment.

It is as described below that the utility model solves the technical scheme that its technical problem adopts: a kind of mutual charging circuit of charging mutually of realizing between electronic equipment, comprise electronic equipment body, it is characterized in that, described electronic equipment body is four-core socket, in described electronic equipment body, charging module is installed, this charging module is connected with electric device battery, this charging module includes synchronous boost chip, synchronous boost chip and electric capacity and inductance form high-frequency oscillating circuits and boost, by output resistance capable of regulating charging voltage, thereby realize another electronic equipment charging.

This is a kind of realizes between electronic equipment mutual charging circuit of charging mutually and also comprises a charging connection wire, and one section of termination of charging connection wire coordinates with charged electronic equipment socket, another termination be recharged electronic equipment socket and coordinate.

According to the utility model of said structure, its beneficial effect is, the utility model is further perfect on the basis of existing electronic equipment charging technique, realization is under some specific environments, to the object of electronic equipment charging, it is simple in structure, easy to use rapidly. ?

Accompanying drawing explanation

Below in conjunction with accompanying drawing and embodiment, the utility model is described further.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model circuit theory diagrams.

Embodiment

As Figure 1-Figure 2, a kind of mutual charging circuit mutually charging between electronic equipment of realizing, comprise electronic product body, it is characterized in that, on described electronic product body, be installed in addition with four-core socket, in described electronic product body, charging module is installed, this charging module is connected with electronic product battery, this charging module includes synchronous voltage booster circuit, synchronous voltage booster circuit is integrated into the chip that boosts, synchronous boost chip and electric capacity and inductance form high-frequency oscillating circuits and boost, by output resistance, adjust charging voltage, thereby can realize another electronic product charging.The mutual charging circuit that this kind can be realized between electronic product charging mutually also comprises a charging connection wire, and charging connection wire one end coordinates with the electronic product socket that charges, another termination be recharged electronic product socket and coordinate.

Switch of the present utility model is to realize like this, on electric discharge electronic equipment socket, be installed in addition with four-core socket (1,2,3,4), when plug is inserted to electronic equipment socket, in socket (1,2) two cores are communicated with, so charging circuit is started working, enter discharge condition, plug is connected with the charging socket on electronic equipment to be charged in addition, can realize charging.If do not insert the plug that four-core is housed, 1,2 liang of core disconnects, and charging circuit is not worked.

The utility model is by high efficiency synchronous voltage booster circuit is installed in electronic equipment, thereby it is chargeable mutually to have realized electronic equipment.

The utility model turns on and off this circuit by patchcord, thereby when electronic equipment does not externally charge, the accumulation of energy of not loss electronic equipment internal.

The utility model can design different plugs according to distinct electronic apparatuses charging socket, makes it can be applicable in various electronic equipments.
