Abstract
The utility model discloses a universal USB standby power supply for mobile phones, which comprises a USB interface, a charging module and a battery, wherein the USB interface is connected with the charging module, and the charging module is connected with the battery. In the utility model, the convenient USB standby power supply is provided for mobile phones without influencing the structures of mobile phones, and is suitable for all the mobile phones with USB interfaces.
Description
Technical field
The utility model relates to the mobile communication technology, the omnipotent USB stand-by power supply of particularly a kind of mobile phone.
Background technology
What existing mobile phone adopted is that lithium battery provides power supply to mobile phone, in the lithium battery quantity not sufficient, just need give lithium cell charging by charger for mobile phone.Because the lithium battery electric weight of mobile phone is limited, the user need keep continuing conversation, will carry charger for mobile phone and under the environment that the 220V AC power is arranged to cell-phone charging, can the user who be away from home be made troubles like this.
The utility model content
The technical problems to be solved in the utility model is in order to overcome the defective of prior art, provide a kind of mobile phone omnipotent USB stand-by power supply, it can be when not influencing handset structure, the USB stand-by power supply of providing convenience and using to mobile phone, and it is not at certain mobile phone, and is fit to possess all mobile phones of USB interface.
The utility model solves above-mentioned technical problem by following technical proposals: the omnipotent USB stand-by power supply of a kind of mobile phone, it is characterized in that it comprises USB interface, charging module and battery, and USB interface is connected with charging module, and charging module is connected with battery.
Positive progressive effect of the present utility model is: battery capacity of the present utility model can customize, and uses USB interface to bring convenience; The utility model is fit to all identical mobile devices of interface, can make the power supply of various standard usb interfaces; Shape profile of the present utility model can design voluntarily, as make with the phone housing shape relatively as, in order to avoid mobile phone is used in influence, be easy to carry.
Description of drawings
Fig. 1 is the schematic diagram of the utility model one embodiment.
Embodiment
Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
As shown in Figure 1, the omnipotent USB stand-by power supply of the utility model mobile phone comprises usb 1 01, charging module 102 and battery 103, and usb 1 01 is connected with charging module 102, and charging module 102 is connected with battery 103.
After mobile phone does not have electricity, need not pull up battery, directly the omnipotent USB stand-by power supply of mobile phone be inserted by mobile phone USB interface, can power.The omnipotent USB stand-by power supply of mobile phone is inserted computer USB interface, perhaps use the USB charger, can realize charging.When the omnipotent USB stand-by power supply of mobile phone charges by USB interface, after USB interface is identified, provide charge power supply, give the battery accumulate by charging module then by the USB circuit.When the omnipotent USB stand-by power supply of mobile phone inserts mobile phone USB interface, transfer to by the USB interface power supply, rather than mobile phone battery originally, the situation when just connecting the USB line with mobile phone is the same.
Though more than described embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these execution modes.Therefore, protection range of the present utility model is limited by appended claims.
