Abstract
The utility model discloses a two time meter core using a same core, which is characterized in that: a pointer and a digital timing apparatus are driven synchronously by a quartz oscillator and an integrated circuit, a stable oscillation frequency generated by the quartz oscillator is divided by a frequency divider in an IC, on one side, a part of output pulse signal with the frequency 0.05Hz is transmitted to a stepping motor, driving the stepping motor to make a driving wheel to rotate, on the other side, a part of output pulse signal driving the digital display for the hour, minute and second is transmitted to a conductive rubber, driving an LCD to display a time. The utility model has the advantages of a same quartz oscillator and a same IC driving the pointer and the digital timing apparatus without an error, and having low construction cost and simple assembly process because a quartz oscillator and an IC are saved.
Description
Technical field
The utility model belongs to electronic watch watch core field, relates in particular to quartz watch watch core field.
Background technology
Quartz watch generally has pointer and digital two kinds.The pointer quartz table produces stable oscillation frequency by quartz (controlled) oscillator, frequency divider frequency division through the CMOS integrated circuit is a pulse signal, drive stepping motor is rotated, drive indicator device by train, it is accurate when the pointer quartz table is walked, simple in structure, the wearing and tearing of its gear train are less, and serviceable life is longer.Digital quartz watch then is the pulse signal that the oscillation frequency with quartz (controlled) oscillator is a different frequency by the different counter frequency divisions in the frequency divider, encoded decoding back shows the time (being called for short LCD) with LCD with digital form, the digital quartz watch cost is lower, by cooperating different on-off circuits and counter, also can have functions such as calendar, alarm clock, stopwatch, but digital quartz watch is more fragile, and durability is relatively poor.
The quartz watch that has adopts two watch cores, has dual clocking capability, its inside is installed in pointer watch movement and digital watch movement on the support, the outside pointer watch movement of stirring of stirring handle by a pointer, two adjustment digital watch movements that electronics is pressed, but because its pointer watch movement and digital watch movement respectively have a quartz (controlled) oscillator and an integrated circuit (hereinafter to be referred as " IC "), there is error between the oscillation frequency of two movement quartz (controlled) oscillators, makes also to have the two instruction time error; The Quartzcrystal watch movement complex structure of this structure of while, manufacturing cost is higher, and assembly technology is also complicated.
Summary of the invention
Fundamental purpose of the present utility model provides quartz (controlled) oscillator of a kind of synchronous employing and an IC drives, and has the quartz watch watch core of the dual clocking capability of pointer digital display.
For achieving the above object, the utility model mainly comprises support, mechanism when pointer is walked, mechanism when numeral is walked, wiring board and battery, have pointer demonstration mouth on the support and show mouth with numeral, mechanism was fastened in cradle back shows mouth over against pointer position when pointer was walked, mechanism was fastened in cradle back shows mouth over against numeral position when numeral was walked, battery is positioned in the battery case of cradle back, the wiring board locking is covered in cradle back, position of corresponding battery has corresponding breach on it, mechanism was by base plate when pointer was walked, stepping motor, train, cover plate is formed, stepping motor and train all are fixed on the base plate, last overlay sealing; Mechanism was made up of LCD and conductive rubber when numeral was walked, and conductive rubber is close to LCD; Wiring board is provided with continuous quartz (controlled) oscillator and integrated circuit, and this integrated circuit links to each other with stepping motor, conductive rubber; The both positive and negative polarity of battery all links to each other with quartz (controlled) oscillator, integrated circuit.
After adopting said structure, quartz (controlled) oscillator produces stable oscillation frequency, behind the frequency divider frequency division in IC, the pulse signal of output 0.05Hz is given stepping motor, the driving stepping motor rotates, drive train again and rotate, IC also exports when driving simultaneously, the pulse signal of minute, second digital display is given conductive rubber, drives LCD and shows the time.Mechanism was driven by same quartz (controlled) oscillator and an IC when mechanism and numeral were walked when the pointer of this structure was walked, and do not have error, and owing to saved a quartz (controlled) oscillator and an IC, cost was lower, and whole assembly technology is also simpler.
