Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
See figures.1.and.2, the utility model provides a kind of charger 10, the body 12 comprising plug 11 and be connected with plug 11, the housing 121 that described body 12 comprises pedestal 122 and covered by pedestal 122, charging circuit 100 and indicator light 103 is provided with in the space that described pedestal 122 and housing 121 enclose, described charging circuit 100 connects described indicator light 103, when this charger charges to battery, after the voltage of battery reaches preset value, described indicator light 103 turns of lamps, described charging circuit 100 comprises the voltage conversion circuit 101 for outer power voltage being converted to low-voltage, and for controlling the controller 102 of described indicator light 103 luminescence, described controller 102 has A/D translation function (analog conversion function) and PWM function (pulse width modulated function) described controller 102 switches on power in order to work as this charger, and charge the battery, and when not reached described preset value by the voltage of the battery charged, controlling described indicator light 103, to present the type of respiration that light and shade replaces luminous, and its respiratory rate is slack-off gradually with the prolongation in charging interval.
Concrete, when the plug 11 of charger 10 connect external power source charge the battery time, described indicator light 103 is luminous, when being reached preset value by the voltage of battery charged, described indicator light 103 turns of lamps.It should be noted that, described indicator light 103 is dichromatic LED.The rated voltage of the battery of mobile terminal is generally at about 4.2v, described preset value can be the numerical value close to 4.2V such as 3.9v, 4.0v or 4.1V, when being reached preset value by the battery charged, can think that battery has been filled electricity (magnitude of voltage reach 95% of rated voltage can think be full of), now bi-color light emitting diode turns lamp (becoming green from redness), is filled electricity in order to pilot cell.
Charging circuit 100 comprises voltage conversion circuit 101 and controller 102, concrete, described voltage conversion circuit 101 comprises input and output, and described input is for connecting external power source, described output is connected in the output interface on this charger 10, for charging the battery.Described output comprises positive output end and negative output terminal, described negative output terminal is provided with a current sense resistor R7, after arranging this current sense resistor R7, when charger switches on power, the size of current of described negative output terminal diminishes gradually with the prolongation in charging interval.Described controller 102 comprises a single-chip microcomputer, and for controlling described indicator light 103, to present the type of respiration that light and shade replaces luminous; As 80 series or the serial single-chip microcomputer of XY27x.The positive output end of described voltage conversion circuit 100 connects the power pins (No. 8 pins in Fig. 2) of described single-chip microcomputer, the negative output terminal of described voltage conversion circuit 100 connects A/D conversion input pin (No. 7 pins in Fig. 2) of described single-chip microcomputer, the driver output pin (3,4,5, No. 6 pins in Fig. 2) of described single-chip microcomputer connects described indicator light 103, grounding pin (No. 1 pin in Fig. 2) ground connection of described single-chip microcomputer.When described charger is charging the battery, and when not reached described preset value by the voltage of the battery charged, the type of respiration that described Light-Emitting Diode (indicator light 103) replaces in light and shade is luminous.
In addition, the voltage U at described current sense resistor R7 two ends diminishes gradually along with the continuity in charging interval, when just starting to charge, U is maximum, after this voltage signal enters an A/D conversion input pin, this signal can be detected all the time in described single-chip microcomputer inside, and reduced gradually by the output frequency of driver output pin, thus the light-emitting diode (D1, D2, D3, D4) that driver output pin connects breathes the frequency step-down gradually of flicker.When U is reduced to certain value (namely being reached preset value by the voltage of the battery charged), described light-emitting diode type of respiration luminescence stops, and transfers to green fixing luminous, now represents that battery is filled electricity.
It should be noted that herein, the annexation of described positive output end, negative output terminal and Light-Emitting Diode and described single-chip microcomputer is not limited to above-mentioned connected mode, as long as above-mentioned this charger of working as can be realized to switch on power, and when not reached described preset value by the voltage of the battery charged, described controller controls described indicator light, and to present the type of respiration that light and shade replaces luminous, further, the object that respiratory rate is slack-off gradually with the prolongation in charging interval.
The utility model by arranging controller 102 in charger 10, when this charger switches on power, described controller 102 can control described indicator light 103, and to present the type of respiration that light and shade replaces luminous, and its respiratory rate is slack-off gradually with the prolongation in charging interval, like this, user can roughly judge by the charge condition of rechargeable battery according to the respiratory rate of this indicator light type of respiration luminescence very intuitively.
Further, with reference to Fig. 2 and Fig. 3, described housing 12 surface is provided with the first sheet metal 13, described first sheet metal 13 is changed input pin with the 2nd A/D of described single-chip microcomputer and is connected, described single-chip microcomputer is configured to when this charger 10 charges the battery, and user can regulate the brightness of described indicator light 103 by touching described first sheet metal 13.
In the present embodiment, described housing 12 surface is provided with the first sheet metal 13, described first sheet metal 13 is changed input pin with the 2nd A/D of described single-chip microcomputer and is connected, this single-chip microcomputer is configured to when this charger switches on power, user can regulate the brightness of described indicator light 103 by touching described first sheet metal 13 (the C point in Fig. 2), concrete, described first sheet metal 13 is changed input pin with the 2nd A/D of single-chip microcomputer described in this and is connected.Because staff all can with a certain amount of electric charge, there is faint potential difference over the ground, when staff touches the first sheet metal 13, the 2nd A/D that this faint signal of telecommunication will be delivered to this single-chip microcomputer changes input pin (No. 2 pins in Fig. 2), a larger signal of telecommunication can be obtained after this single-chip microcomputer amplifies process, the output being controlled the light-emitting diode of this single-chip microcomputer by this signal of telecommunication drives the duty ratio of mouth output signal, the duty ratio of initial default state is 100%, enter when state is set (touch the first sheet metal 13 and keep 3 seconds), duty ratio reduces 10%, continuous touch, then duty ratio reduces continuously, when duty ratio is reduced to 0%, duty ratio is with 10% step increments, reach 100% to duty ratio and namely repeat previous circulation.When the luminosity one of this light-emitting diode touches for the last time, duty ratio determined.It should be noted that herein, with reference to Fig. 5, can also be connected with described 2nd pin with the metal shell of the usb 16 of the output port of this charger, substitute the first sheet metal 13 and be connected with the 2nd pin, the brightness regulating described indicator light 103 can be realized equally.
