Abstract
An intelligent mobile phone charger is formed by a program control switch, a charging module, a USB interface, a battery level reading and controlling module, and a plug, which are mounted inside a casing. When the intelligent mobile phone charger is used to charge a mobile phone, the battery level reading and controlling module reads the battery level of the mobile phone from a charging data line of the mobile phone through the USB interface in a real-time manner and sends an instruction for turning off power supply to the program control switch when a battery is detected to be fully charged; and after receiving the instruction for turning off the power supply, the program control switch instantly turns off the power supply to stop charging, thereby effectively preventing the life of the battery from being shortened due to overcharging and preventing damages from being caused.
Description
Technical field
The utility model relates to a kind of smart mobile phone charger.
Background technology
Existing charger for mobile phone does not have the cell-phone battery electric-charge quantity read functions, can not automatically stop charging after battery is full of electricity, overcharges for a long time and will shorten battery life, even damage battery.
Summary of the invention
In order to overcome the deficiency of existing charger for mobile phone, the utility model provides a kind of smart mobile phone charger, this smart mobile phone charger reads in real time the electric weight of battery of mobile phone by the data wire to cell-phone charging in charging process, when it detects battery and is full of electricity, just automatically stop charging.
The technical scheme that its technical problem that solves the utility model adopts is: this smart mobile phone charger is by being installed in that grammed switch, charging module, USB interface, an electric weight in the housing reads and control module and plug form, it is characterized in that: grammed switch is for can accept monolithic processor controlled mains switch, its signal input part is connected on the signal output part of single-chip microcomputer, controls power connection and the disconnection of whole circuit; Electric weight reads and control module is to move the single-chip microcomputer of electric weight fetch program and control program; The power end of USB interface is connected with charging module, and data terminal reads with electric weight and the signal input part of control module is connected; Grammed switch is connected in charging module and electric weight reads and control module is in parallel to be formed the circuit; Plug is connected on the DC output end of charging module; In the process to cell-phone charging, electric weight reads and control module reads the battery electric quantity of mobile phone in real time from the data wire to cell-phone charging by USB interface, when it detects battery electric quantity and has expired, then send the instruction of powered-down to grammed switch, grammed switch receives after the instruction of powered-down that powered-down stops charging immediately.
The beneficial effects of the utility model are that this smart mobile phone charger can stop charging automatically after battery of mobile phone is full of electricity, can prevent effectively that battery from shortening the life-span and causing damage because overcharging.
