Abstract
A quick charger for mobile phones comprises a charger shell and a charger body installed inside the charger shell. The charger shell is provided with an USB interface, a quick charging indicator and a common charging indicator. The charger body contains a rectifying circuit module, a 5V or 9V or 12V automatic charging module, a 5V to 9V or 12V automatic switching module and a control chip. The rectifying circuit module is connected with the 5V or 9V or 12V automatic charging module through a transformer. The 5V or 9V or 12V automatic charging module is connected with the USB interface. The 5V to 9V or 12V automatic switching module is also connected to the USB interface. The 5V or 9V or 12V automatic charging module, the 5V to 9V or 12V automatic switching module, the transformer, the quick charging indicator and the common charging indicator on the charger shell are all connected with the control chip. By arranging the automatic charging module, the automatic switching module and the control chip, charging voltage is automatically switched and adjusted. Thus, charging safety is raised, and charging time is shortened.

Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of reasonable in design, easy to use, has improved the fail safe of mobile phone charging, shortens the mobile phone quick charger in charging interval.
Technical problem to be solved in the utility model is to realize by following technical scheme, the utility model is a kind of mobile phone quick charger, comprise charger shell and be contained in the charger body in charger shell, on described charger shell, be provided with USB socket and common charging indicator light, be characterized in, on described charger shell, be also provided with quick charge indicator light, described charger body comprises rectification circuit module, 5V or 9V or 12V automatic charging module, 5V is to 9V or 12V automatic switching module and control chip, rectification circuit module is connected by transformer and 5V or 9V or 12V automatic charging module, 5V or 9V or 12V automatic charging module are connected with USB socket by connection, described 5V is also connected on USB socket by connection to 9V or 12V automatic switching module, described 5V or 9V or 12V automatic charging module, 5V is to 9V or 12V automatic switching module, transformer, quick charge indicator light on charger case is all connected with control chip with common charging indicator light.
Technical problem to be solved in the utility model can also further realize by following technical scheme, in above-described mobile phone quick charger: described control chip is single-chip microcomputer.
The utility model, by establishing 5V or 9V or 12V automatic charging module, is first given mobile phone trickle charge, has realized automatic adjustment, the automatic switchover of voltage in charging process, provides good protection to battery of mobile phone; If it is too high that 5V to 9V or 12V automatic switching module, prevents that battery of mobile phone temperature from continuing, affect the life-span of battery of mobile phone; 5V or 9V or 12V automatic charging module are connected with transformer, quick charge indicator light, common charging indicator light by control chip to 9V or 12V automatic switchover mould with 5V, realize the switching of quick charge and common charging, and good monitoring is provided to voltage height and mobile phone charge condition in charging process, has further improved the fail safe of charger and mobile phone.Compared with prior art, it is reasonable in design, easy to use, automatically switches and adjusts charging voltage, has improved the fail safe of charging, when keeping charging mobile phone battery power constant, has shortened the charging interval.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
Embodiment 1, with reference to Fig. 1, a kind of mobile phone quick charger, comprise charger shell and be contained in the charger body in charger shell, on described charger shell, be provided with USB socket and common charging indicator light, on described charger shell, be also provided with quick charge indicator light, described charger body comprises rectification circuit module, 5V or 9V or 12V automatic charging module, 5V is to 9V or 12V automatic switching module and control chip, rectification circuit module is connected by transformer and 5V or 9V or 12V automatic charging module, 5V or 9V or 12V automatic charging module are connected with USB socket by connection, described 5V is also connected on USB socket by connection to 9V or 12V automatic switching module, described 5V or 9V or 12V automatic charging module, 5V is to 9V or 12V automatic switching module, transformer, quick charge indicator light on charger case is all connected with control chip with common charging indicator light.
Embodiment 2, in the mobile phone quick charger described in embodiment 1, described control chip is single-chip microcomputer.
First, convert alternating current to DC circuit by rectification circuit module, DC circuit is through transformer and 5V or 9V or 12V automatic charging module, first adopt 5V constant voltage mode to mobile phone trickle charge, after trickle charge, situation is fed back to control chip, control chip control transformer switches to 9V or 12V constant voltage mode to charging mobile phone battery, and this fast charge mode has been saved electric weight, has improved 80%～140% charge efficiency; In the time that rechargeable cellphone battery temperature exceedes the temperature of mobile phone setting, mobile phone terminal feeds back to control chip to 9V or 12V automatic switching module by situation by 5V, control chip control transformer, charging voltage is down to 5V charging, to ensure the charging safety of battery of mobile phone, in the time that battery of mobile phone temperature drops to set point, then charging voltage is increased to 9V or 12V, and charger shell is provided with corresponding indicator light, there is good visuality.
