Abstract

A rapid mobile phone charger comprises a charger shell and a charger body installed inside the charger shell. A USB socket, a rapid charging indicator lamp and a normal charging indicator lamp are arranged on the charger shell. The charger body comprises a rectifying circuit module, a 5 V or 9 V or 12 V automatic charging module, a 5 V or 9 V or 12 V automatic switching module and a control chip. The rectifying circuit module is connected with the 5 V or 9 V or 12 V automatic charging module through a transformer. The 5 V or 9 V or 12 V automatic charging module is connected with the USB socket. The 5 V or 9 V or 12 V automatic switching module is further connected to the USB socket. The 5 V or 9 V or 12 V automatic charging module, the 5 V or 9 V or 12 V automatic switching module, the transformer, and the rapid charging indicator lamp and the normal charging indicator lamp of the charger shell are all connected with the control chip. According to the rapid mobile phone charger, due to the arrangement of the automatic charging module, the automatic switching module and the control chip, the charging voltage is automatically switched and adjusted, charging safety is improved, and the charging time is shortened.

Description

Mobile phone quick charger

Technical field

The present invention relates to a kind of charger for mobile phone, particularly a kind of mobile phone quick charger.

Background technology

Existing charger for mobile phone is all to adopt 85V ~ 265V alternating current to input, and exports with 5V direct current.Along with the development of smart mobile phone industry, battery of mobile phone capacity is increasing, charging interval of existing charger corresponding also can be more and more longer, make troubles to consumer, meanwhile, in order to guarantee that the charging interval is in the scope of consumer's reception, the charging current of battery of mobile phone is also increasing, but charging current can not unconfinedly improve, charging current exceedes 2.25A for a long time can bring potential safety hazard to the charging wire rod of mobile phone charge port and charger, causes the charging interval of high capacity cell to become longer.

Summary of the invention

Technical problem to be solved by this invention 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 by this invention is to realize by following technical scheme, the present invention 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 by this invention can also further realize by following technical scheme, in above-described mobile phone quick charger: described control chip is single-chip microcomputer.

The present invention, by establishing 5V or 9V or 12V automatic charging module, first gives 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.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Embodiment
