Abstract
The utility model discloses the circuit of a charger of an intelligent portable telephone cell which can speak Chinese and English, and is controlled by a microcomputer used as a core. Chinese and English voice and buzzing prompt can be freely chosen under the control of the microcomputer, and users can also choose a voice closing mode, the microcomputer can simultaneously control a liquid crystal display, and thus, the operating state, the charging and the discharging quantity, the charging and discharging time, etc. of the charger can be obviously displayed. The utility model is convenient for operators as well as is suitable for charging various portable telephone cells.
Description
The utility model relates to charger, and a kind of specifically mobile phone battery that is applicable to has the charger of language intelligence.
At present, the charger of mobile phone battery on the market still has and adopts common transformation rectification circuit, and such charger not only volume is big, and specific volume power is little, and the charging interval is long.In order to address this problem, LCD or LED are arranged in recent years on the market and use buzzer to wait the charger of the small size of indicating charger work, but these chargers will can be made mistakes when not noting with soon when operation, are unconformable at all for the blind person.These chargers have has English Phonetics function and demonstrations such as English, number, but does not have the voice and the Chinese-character display function of Chinese.
The purpose of this utility model is that a kind of various mobile phone batteries that are applicable to will be provided, and easily, has the charger that can say Chinese, personification English intelligence and that have LCD.
The purpose of this utility model is achieved in that this charger adopts microcomputerized control Chinese and English voice to produce chip and produces corresponding voice signal, drives loud speaker; With operating state, the charge/discharge electricity amount of liquid crystal display charger, discharge and recharge the time; Charger can be selected Chinese or English reminding or buzzer prompting by switch when working in wait charged state (stand-by state) simultaneously, can also select to close sound mode or the like.It is characterized in that providing 13.8V voltage by wall formula power supply, the one tunnel forms voltage stabilizing circuit through resistance R 4 to three terminal regulator U3 and capacitor C 3, C4, C5, C6; Another route triode Q1, resistance R 1, R2, R3, capacitor C 7, inductance L 1 and diode D1, D2 form charging control circuit; By voltage system pulse width controller U2, resistance R 5, R6, R7, R8, R9, R10, R11, capacitor C 8, C9, triode Q3, Q4 form the electric current constant-current control circuit; The A/D conversion input that is met microcomputer U1 by resistance R 13, R14, R15 is formed the electric weight testing circuit; Connect another A/D conversion input of microcomputer U1 by resistance R 17, R18, R19 and form current detection circuit; By resistance R 16, R12, R27, diode D3, D4, triode Q5 forms discharge circuit.During work by wall formula power supply provide 13.8V voltage one tunnel through the cloudy R utmost point of electricity offer by three terminal regulator U3 spare and capacitor C 3, C4, C5, C6 form+5 with V voltage offer complete machine work.Another road offers by triode Q1, resistance R 1, R2, R3, capacitor C 7, and inductance L 1 and diode D1, D2 are as charging; By voltage system pulse width controller U2, resistance R 5, R6, R7, R8, R9, R10, R11, capacitor C 8, C9, triode Q3, Q4 produce the variable constant current of size of current to battery charge to size of current and constant-current control circuit control charging control circuit; Carry out charge/discharge electricity amount and detect being recharged A/D conversion input that cell voltage carries out giving after the dividing potential drop microcomputer U1 by resistance R 13, R14, R15; Resistance R 17, R18, R19 are converted to another A/D conversion input detection charging current value that magnitude of voltage is given microcomputer U1 then to charging current value.During to battery discharge, microcomputer U1 sends a high level when using nickel-cadmium cell, and through diode D4, resistance R 12 is added to the base stage of triode Q5, makes it saturated, and battery discharges over the ground via resistance R 16, diode D3, triode Q5.
The utility model makes Chinese and English voice generation chip and buzzer can choose at random wherein one of prompting because adopted the control of microcomputer, again can be according to selecting to adopt the sound mode of closing; Simultaneously the utility model has been because used LCD, so the operating state of charger, charge/discharge electricity amount, discharge and recharge time etc. and can present at a glance, therefore can reach the order of drafting, and make things convenient for operator's needs widely.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the utility model structure line map.
Be core with microcomputer U1 among the figure, the upper end is connected with liquid crystal display (1) frequently, and the lower side is connected with Chinese and English voice and produces chip U4, and the front end that Chinese and English voice produce chip U4 is connected with audio power amplifier circuit, and the end of audio power amplifier circuit is loud speaker (2).Circuit is characterised in that by wall formula power supply among the figure provides 13.8V voltage, and one the tunnel forms voltage stabilizing circuit through resistance R 4 to three terminal regulator U3 and capacitor C 3, C4, C5, C6.Another route triode Q1, resistance R 1, R2, R3, capacitor C 7, inductance L 1 and diode D1, D2 form charging control circuit; By voltage system pulse width controller U2, resistance R 5, R6, R7, R8, R9, R10, R11, capacitor C 8, C9, triode Q3, Q4 form the electric current constant-current control circuit; The A/D conversion input that is met microcomputer U1 by resistance R 13, R14, R15 is formed the electric weight testing circuit; Another A/D conversion input that is met microcomputer U2 by resistance R 17, R18, R19 is formed current detection circuit; By resistance R 16, R12, R27, diode D3, D4, triode Q5 forms discharge circuit.
The work of the utility model complete machine is by microcomputer U1 control, and microcomputer U1 itself has liquid crystal and drives and put band A/D conversion mouth.By charge-discharge circuit, lithium battery, nickel-cadmium cell, the Ni-MH battery that can be used the mobile phone of various different voltages effectively by microcomputer U1 control charge.Wherein Zui Da characteristics are to have Chinese, English and buzzer prompting, and can select a kind of in three kinds at any time.
