Description
One, technical field
The utility model relates to a kind of power pack, relates in particular to a kind of power pack with USB interface.
Two, background technology
At present the electrical appliance of band USB interface is of a great variety, be extensive use of, but its power supply that adopts relatively limits to, and all can not mate use on general supply socket, power pack, because of not having USB interface it on.The power supply of USB interface is the most extensive from computer, on the computer, therefore generally all pegs graft on computers with the electrical appliance of USB interface, could use to the computer energising and after needing to open computer, brings certain limitation for the use of band USB interface electrical appliance.
Three, utility model content
The purpose of this utility model is to provide a kind of power pack with USB interface, can solve the problem that the existing power supply box can't be given the electrical appliance power supply of USB interface effectively.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: chargeable and electric power storage and with the power pack of USB interface, comprise housing, power line and plug, it is characterized in that: described housing is provided with USB interface, be provided with supply module, power storage module and power management module in the described housing, described power line is connected with supply module with plug, and described supply module, power storage module are connected with power management module respectively, and described power management module is connected with USB interface.
Good effect of the present utility model is, can provide power supply for the electrical appliance of band USB interface, promptly can be it on electrical appliance only need be pegged graft with USB interface power supply is provided, enlarge the scope of application of the electrical equipment of band USB interface greatly, the utility model is simple in structure, reliable, practical simultaneously.
Four, description of drawings
Fig. 1 is for the chargeable and electric power storage of the utility model and with the structural representation of the power pack of USB interface.
Five, embodiment
As shown in Figure 1, chargeable and electric power storage and with the power pack of USB interface, comprise housing 4, power line and plug 2, it is characterized in that: described housing 4 is provided with USB interface 6, be provided with supply module 1, power storage module 3 and power management module 5 in the described housing 4, described power line is connected with supply module 1 with plug 2, and described supply module 1, power storage module 3 are connected with power management module 5 respectively, and described power management module 5 is connected with USB interface 6.
Described chargeable and electric power storage also with the operation principle of the power pack of USB interface with workflow are: when power line and plug 2 and external power source (civil power) when being connected, power management module 5 judges whether power storage module 3 has been held full, if do not hold full, then be power storage module 3 chargings, hold completely until power storage module 3, stop to be its power supply; Simultaneously, power management module 5 utilizes supply module 1 to be USB interface 6 power supplies.When plug 2 is not connected with external power source, when promptly supply module 1 can't be powered, it was USB interface 6 power supplies that power management module 5 utilizes the electric energy in the power storage module 3.Promptly can be it on electrical appliance only need be pegged graft with USB interface 6 power supply is provided.
