The utility model discloses a mobile power supply for a mobile phone and belongs to the technical field of mobile power supplies. The mobile power supply mainly comprises a shell, wherein a cavity is mounted on the shell; a battery power supply and a power panel are mounted in the cavity; a control circuit for charging and discharging a battery power supply is arranged on the power panel; and a mobile phone interface and a power interface are arranged on the shell, and are respectively connected with the control circuit. The mobile power supply provided by the utility model can be used to charge the mobile phone not provided with a fixed power supply, thereby being extensively applicable to daily use of the mobile phone.
Description
Technical field
The utility model relates to the portable power source technical field, relates in particular to a kind of mobile phone portable power source.
Background technology
Mobile phone has become popular communication tool commonly used, along with development of science and technology, the effect of mobile phone is also increasingly extensive, the capacity of battery of mobile phone all is limited usually, in use, tend to run in the process of making a phone call, battery electric quantity is low excessively, can't normal talking, at this moment just need mobile phone is charged or changes battery.At present, the cell-phone charging mainly trip of dependence fills or seat such as fills at mains charger, and these all need fixed power source, if the user on the road, do not have suitable fixed power source, and the continuation that influences mobile phone is normally used.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of mobile phone portable power source, to solve the technical problem that mobile phone charges when not having fixed power source.
For solving the problems of the technologies described above, the technical solution of the utility model is: the mobile phone portable power source, comprise housing, described housing is provided with the installation cavity, be provided with battery supply and power panel in the described installation cavity, described power panel is provided with the control circuit that is used for described battery supply charging, discharge, and described housing is provided with handset port and power interface, and described handset port is connected with described control circuit respectively with power interface.
As a kind of improvement, described control circuit comprises short-circuit protection circuit, current foldback circuit, discharge protection circuit, overcharge protection circuit.
As a kind of improvement, described housing is provided with the one group of indicator light that is used to show described battery supply electric weight.
As a kind of improvement, described battery supply is a lithium battery.
As a kind of improvement, described housing comprises upper shell and the lower house that links together.
After having adopted technique scheme, the beneficial effects of the utility model are: owing to be provided with battery supply and power panel in the installation cavity of mobile phone portable power source, power panel is provided with and is used for the battery supply charging, the control circuit of discharge, therefore the mobile phone portable power source can be connected and fixed power supply, make battery supply charged, and it is electrically charged to discharge institute, and volume is little, easy to carry, when the mobile phone electric weight is crossed when low, can directly use the mobile phone portable power source that mobile phone is charged, overcome the defective that mobile phone must charge on fixed power source, make things convenient for the cellie normally to use.
Because control circuit comprises short-circuit protection circuit, current foldback circuit, discharge protection circuit, overcharge protection circuit; make the mobile phone portable power source more safe and reliable in charging and discharge process; can make that neither the battery supply of mobile phone portable power source is damaged; can not make that the battery of mobile phone that is recharged is damaged, and has prolonged the battery supply of mobile phone portable power source and the useful life of battery of mobile phone yet.
Because housing is provided with the one group of indicator light that is used to show described battery supply electric weight, make when the mobile phone portable power source uses conveniently, use more intuitively, can give the prompting of user with anticipation in advance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: 1, upper shell, 2, lower house, 3, handset port, 4, power interface, 5, lithium battery, 6, power panel, 7, indicator light, 8, the start button.
Embodiment
As shown in drawings, a kind of mobile phone portable power source, mainly comprise housing, in order to install with easy to make, described housing comprises upper shell 1 and the lower house 2 that links together, described housing is provided with the installation cavity, be provided with battery supply and power panel 6 in the described installation cavity, described power panel 6 is provided with the control circuit that is used for described battery supply charging, discharge, described battery supply is preferably lithium battery 5 commonly used at present, described housing is provided with handset port 3 and power interface 4, and described handset port 3 is connected with described control circuit respectively with power interface 4.
Safety in order to make lithium battery 5 chargings and discharge makes the lithium battery 5 of mobile phone portable power source and battery of mobile phone have longer useful life, and described control circuit comprises short-circuit protection circuit, current foldback circuit, discharge protection circuit, overcharge protection circuit.When output was short-circuited, circuit output voltage made zero, and played the short-circuit protection effect; Circuit enters guard mode when charging current is higher than 1.5A, stops cell-phone charging being played overcurrent protection; Circuit enters guard mode when lithium battery 5 voltages are lower than 3V, stops cell-phone charging, plays the discharge prevention effect; When lithium battery 5 voltages reach 4.23V, circuit stops the over-charge protective effect is played in the charging of mobile phone portable power source.
Described housing is provided with the one group of indicator light 7 that is used to show lithium battery 5 electric weight, and design has four LED light 7 usually, the height of expression electric weight, and when four LED light 7 all lighted, the electric weight of expression lithium battery 5 was the highest.
During the charging of mobile phone portable power source, power interface 4 inserts the adapter of computer USB or 5V1A, enters charged state, charging indicator light 7 shiny reds, and when lithium battery 5 is full of, charging indicator light 7 bright greens, output 5V ± 0.2V; Charging or when being full of, by 8, four indicator lights of start button, 7 indication current electric quantity, electric weight indicator light 7 extinguished in bright five seconds automatically, and output 5V ± 0.2V does not change, and the cell-phone charging state does not change.
The discharge of mobile phone portable power source is when promptly charging to mobile phone, by start button 8, four indicator light 7 indication current electric quantity, handset port 3 output 5.0V ± 0.2V inserted mobile phone in ten seconds, mobile phone was pointed out charged state or external power supply state, the mobile phone operate as normal within ten seconds.When battery of mobile phone will be full of, electric current was during less than 50mA or Light Condition, timing shutdown about ten seconds.By start button 8,7 shutdown automatically in bright a second of electric weight indicator light.
The utility model is not limited to above-mentioned concrete execution mode, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection range of the present utility model.
