The utility model content
Technical problem to be solved in the utility model is: provide a kind of multifunctional digital code portable power source, to solve the technical problem that digital product 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 multifunctional digital code 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 and is used for described battery supply charging, the control circuit of discharge, described housing is provided with the start button, described start button connects described power panel, an end face of described housing is provided with power input interface, another end face of described housing is provided with has two power output interfaces at least, and described power output interface is connected with described control circuit respectively with power input interface.
As a kind of improvement, described power output interface comprises USB interface and circular hole 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 display screen that is used to show described battery supply electric weight and operating state.
As a kind of improvement, described housing comprises upper shell and the lower house that is installed together.
As a kind of improvement, described battery supply is a poly-lithium battery.
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 multifunctional digital code portable power source, power panel is provided with and is used for the battery supply charging, the control circuit of discharge, and the multifunctional digital code portable power source is provided with has two power output interfaces at least, therefore the multifunctional digital code portable power source can be connected and fixed power supply, make battery supply charged, and it is electrically charged to discharge institute to multiple digital product, volume is little, easy to carry, when the digital product electric weight is crossed when low, can directly use multifunctional digital code portable power source logarithmic code product to charge, overcome the defective that digital product must charge on fixed power source, made things convenient for the digital product user normally to use.
Because control circuit comprises short-circuit protection circuit, current foldback circuit, discharge protection circuit, overcharge protection circuit; make the multifunctional digital code portable power source more safe and reliable in charging and discharge process; can make that neither the battery supply of multifunctional digital code portable power source is damaged; can not make that the digital product battery that is recharged is damaged yet, prolong the useful life of the battery supply and the digital product battery of multifunctional digital code portable power source.
Because housing is provided with the display screen that is used to show battery supply electric weight and operating state, make when the multifunctional digital code 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, poly-lithium battery, 4, power panel, 5, USB interface, 6, the circular hole interface, 7, power input interface, 8, display screen, 9, the start button.
Embodiment
As shown in drawings, a kind of multifunctional digital code 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 is installed together, described housing is provided with the installation cavity, be provided with battery supply and power panel 4 in the described installation cavity, described power panel 4 is provided with and is used for described battery supply charging, the control circuit of discharge, described housing is provided with start button 9, described start button 9 connects described power panel 4, an end face of described housing is provided with power input interface 7, another end face of described housing is provided with has two power output interfaces at least, and described power output interface is connected with described control circuit respectively with power input interface 7, and described power output interface comprises USB interface 5 and circular hole interface 6.
Described housing is provided with the display screen 8 that is used to show described battery supply electric weight and operating state, and described battery supply is preferably poly-lithium battery commonly used 3.
For the safety that makes poly-lithium battery 3 chargings and discharge; make the poly-lithium battery 3 and the digital product battery of multifunctional digital code portable power source have longer useful life, 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 the charging of logarithmic code product, plays overcurrent protection; Circuit enters guard mode when poly-lithium battery 3 voltages are lower than 3V, stops the charging of logarithmic code product, plays the discharge prevention effect; When poly-lithium battery 3 voltages reach 4.2V, circuit stops the over-charge protective effect is played in the charging of multifunctional digital code portable power source.
