Abstract

An intelligent emergency battery with automatic adaptation of voltage comprises a DC power supply BT1, a recognition chip with voltage adaptation U1, a variable voltage chip U4, socket USB2 and JACK1. The variable voltage chip U4, the socket USB2 and the recognition chip with voltage adaptation U1 is electronically connected between the positive electrode and the negative electrode of the DC power supply BT1. The utility model can provides different voltage for the socket JACK1, thereby meets the different voltage requirements of various digital products.

Description

The intelligent standby battery of automatic adapt voltages

Technical field

The utility model relates to a kind of intelligent standby battery, relates in particular to a kind of intelligent standby battery that the automatic adapt voltages that different voltage satisfies different digital products is provided.

Background technology

The operating voltage of the plug of a lot of electronic digital products input at present has nothing in common with each other, basically at 4.2V between the 8.4V.But traditional dc-battery can only provide definite voltage, and therefore the voltage that corresponding input can't be provided can not be accomplished to a plurality of product power supplies to various electronic products.

Summary of the invention

The technical problems to be solved in the utility model is: traditional dc-battery can't provide the voltage that changes corresponding input to various electronic products, can not give a plurality of product power supplies.

For solving the problems of the technologies described above, the utility model proposes following technical scheme: a kind of intelligent battery of automatic adapt voltages, it comprises that a direct current power supply BT1, a voltage adaptation identification chip U1, a transformation chip U4, this transformation chip of a socket USB2, JACK1 U4, socket USB2, JACK1 voltage adaptation identification chip U1 are electrically connected between the both positive and negative polarity of this DC power supply BT1 successively.

The interface of the different model of the corresponding multiple digital product of pegging graft of this plug JACK1.

Signal of telecommunication of plug JACK1 transmission that socket USB2 pegs graft different is to this voltage adaptation identification chip U1.

This voltage adaptation identification chip U1 sends a signal of telecommunication to transformation chip U4, and this DC power supply BT1 provides different voltages to plug JACK1 after adjusting through U4.

The utlity model has following beneficial effect: the utility model, on the basis of general battery, set up voltage adaptation identification chip U1, transformation chip U4, therefore when socket USB2 pegs graft plug JACK1 different, this voltage adaptation identification chip U1 control transformation chip U4, this DC power supply BT1 provides different voltage to plug JACK1, therefore can satisfy the needs of the different voltages of different digital products.

Description of drawings

Fig. 1 is the circuit diagram of the intelligent standby battery of the automatic adapt voltages of the utility model.

Embodiment

See also Fig. 1, a kind of intelligent standby battery of automatic adapt voltages, it comprises a direct current power supply BT1, a voltage adaptation identification chip U1, a transformation chip U4, a socket USB2, a plug JACK1.

This transformation chip U4, socket USB2, plug JACK1 voltage adaptation identification chip U1 are electrically connected between the both positive and negative polarity of this DC power supply BT1 successively.

This voltage adaptation identification chip U1 has the function of adjusting the voltage swing value.

The interface of the different model of digital products such as the corresponding grafting mobile phone of this plug JACK1, PDA, DV, PSP.When plug JACK1 that socket USB2 has pegged graft different, send a signal of telecommunication to this voltage adaptation identification chip U1, this voltage adaptation identification chip U1 calculates and control through program, sending a signal of telecommunication adjusts to transformation chip U4 and carries out, after this transformation chip U4 adjusts, therefore provide correspondent voltage to arrive plug JACK1, scope is at 4.2V, 5-5.5V, 8.4V etc.

The utility model, on the basis of general battery, set up voltage adaptation identification chip U1, transformation chip U4, therefore when socket USB2 pegs graft plug JACK1 different, this voltage adaptation identification chip U1 controls this transformation chip U4 provides different voltage to plug JACK1, therefore can satisfy the needs of the different voltages of different digital products.
