Description
Technical field
The present invention relates to power supply changeover device, particularly relate to a kind of power supply changeover device utilizing battery of notebook computer supply electric power.
Background technology
At present, individual mobile terminal is more and more universal, and power consumption is increasing, but the capacity density of battery does not but have the biggest breakthrough.So exhausting but the emergency that do not has power supply to supply through being commonly encountered battery of mobile terminal, therefore on market, occur in that a lot of jumbo reserve battery.Although this type of battery can provide longer continuing power supply, but weight and volume is bigger than normal.The trip with the crowd of notebook trip, further adding them for every day is born a heavy burden.
Summary of the invention
Present invention is primarily targeted at and a kind of power supply changeover device utilizing battery of notebook computer supply electric power is provided, aim to solve the problem that and do not have when battery of mobile terminal exhausts now power supply supply and the people simultaneously having notebook and other mobile terminals to need to buy extra battery, add the problem that trip is born a heavy burden.
The present invention is achieved in that a kind of power supply changeover device utilizing battery of notebook computer supply electric power, including:
The adapter matched with various battery of notebook computer interfaces, for accessing described power supply changeover device by battery of notebook computer；
Being connected with described adapter, the output activating the output of described battery of notebook computer electric power activates device；
Activate device with described output to be connected, by DC/DC conversion, the high voltage of battery of notebook computer is transformed into the voltage conversion device of the low-voltage that conventional mobile terminal uses；
It is connected with described voltage conversion device, it is provided that mobile terminal inserts the power output connectors of power taking.
In said structure, described output activation device is by some pin ground connection of battery of notebook computer, thus the output of the electric power of activated batteries.
In said structure, described output activates device and sends order by universal serial bus to the power management IC within battery of notebook computer, thus the electric power of activated batteries exports.
In said structure, described voltage conversion device includes at least one road DC/DC change-over circuit, it is provided that different low-voltages.
In said structure, described power output connectors includes one or more in USB interface, round mouth interface and thunder and lightning interface.
In the present invention, in the case of not having alternating current to use, the supply of electric power (capacity of usual battery of notebook computer is up to 44Wh) of overlength can be provided, from without carrying extra portable power source, because notebook itself can be the charging of its battery, so decreasing the quantity carrying power wire, it is provided that organize output voltage, can be that multiple mobile terminal is powered more.
Accompanying drawing explanation
Fig. 1 is the structure chart of a kind of power supply changeover device utilizing battery of notebook computer supply electric power that the embodiment of the present invention provides.
Detailed description of the invention
In order to make the purpose of the present invention, principle and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.

It is connected with described voltage conversion device 300, it is provided that mobile terminal inserts the power output connectors 400 of power taking.
In the present invention, because battery of notebook computer does not has electric power to export in the case of extracting, so needing the electric power output of a device activated batteries.
As one embodiment of the invention, described output activation device 200 is by some pin ground connection of battery of notebook computer, thus the output of the electric power of activated batteries.
As one embodiment of the invention, described output activates device 200 and sends order by universal serial bus to the power management IC within battery of notebook computer, thus the electric power of activated batteries exports.
As one embodiment of the invention, described voltage conversion device 300 includes at least one road DC/DC change-over circuit, it is provided that different low-voltages.
The low-voltage that mobile terminal is conventional has 5V, 6V and 9V etc..
As one embodiment of the invention, described power output connectors 400 includes one or more in USB interface, round mouth interface and thunder and lightning interface.
In order to adapt to the mobile terminal of distinct interface, the present invention is equipped with multiple common mobile terminal power interface.In concrete operations, it is also possible to be converted to above interface by by power output connectors 400 by patchcord.
As one embodiment of the invention, in the case of not having alternating current to use, the supply of electric power (capacity of usual battery of notebook computer is up to 44Wh) of overlength can be provided, from without carrying extra portable power source, because notebook itself can be the charging of its battery, so decreasing the quantity carrying power wire, it is provided that organize output voltage, can be that multiple mobile terminal is powered more.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
