Description
Technical field
The present invention relates to the clock and watch technical field, more specifically, relate to a kind of electronic quartz watch movement.
Background technology
Existing electronic quartz watch movement, the signal of IC output is 1HZ, signal of output in namely one second.Each second drives rotor wheel (having individual permanent magnet and it closely to fix) rotation once (half-turn).Rotor wheel drives power wheel, and power wheel drives second wheel, each second second wheel rotate i.e. 1/60 circle.The second hand of seeing is to jump in one second.The gear ratio of sort signal output is 1/30, and just for example the rotor wheel number of teeth is 8:
Power wheel canine tooth 40
Little tooth 8
Second wheel canine tooth 48
Little tooth 7
The little tooth of second wheel is 7, the third wheel below driving, minute wheel etc.
Speed ratio is so: 8/40 * 8/48=1/30
Because the rotor wheel per second rotates half-turn, (this is the stepper motor designing requirement) as if signal of per second, namely rotor wheel is rotated 1/2 circle.Gu1/2Quan * speed ratio 1/30=1/60, namely the rotor wheel per second rotates, and second wheel just rotates 1/60 circle, just can reach beat effect of second hand on the wrist-watch each second.
But in order to reach the effect that second hand is walked about continuously on the wrist-watch, namely second hand looks and is not to jump in one second (1/60 circle), but the effect of walking about continuously.At present, having only stem-winder is such effect, and electronic quartz shows it is blank.
Summary of the invention
The present invention provides a kind of electronic quartz watch movement for overcoming the described at least a defective of above-mentioned prior art, and it is simple in structure, and second hand can be walked about continuously.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of electronic quartz watch movement, comprise wiring board, the quartz crystal that is electrically connected with wiring board, the stepper motor that is electrically connected with wiring board, described wiring board is provided with IC, wherein, movement also comprise rotor wheel, the power wheel with rotor wheel engagement, the second wheel with the power wheel engagement, axle second of fixedlying connected with second wheel, with a second hand of fixedlying connected second, rotor wheel is connected with stepper motor magnetic; The output frequency of described IC is 3-6HZ, is preferably 4HZ.The IC output signal, quartz crystal produces vibration, and stepper motor produces magnetic force and promotes the rotor wheel rotation, rotor wheel drives power wheel and rotates, power wheel drives second wheel and rotates, because second wheel, second axle, second hand three are fixed together, second hand rotates and is to rotate continuously.
Further, described power wheel comprises that transmission one is taken turns, the transmission two of taking turns engagement with transmission one is taken turns, and transmission one is taken turns and the rotor wheel engagement, and transmission two is taken turns with second wheel and meshed.Take turns with transmission two and take turns by transmission one is set, make movement can satisfy the requirement of speed ratio.
Described transmission one is taken turns and is comprised that canine tooth is taken turns in transmission one and little tooth is taken turns in transmission one, transmission two is taken turns and is comprised that canine tooth is taken turns in transmission two and little tooth is taken turns in transmission two, second wheel comprises second wheel canine tooth and the little tooth of second wheel, the canine tooth engagement is taken turns in rotor wheel and transmission one, little tooth is taken turns in transmission one and the canine tooth engagement is taken turns in transmission two, and little tooth and the engagement of second wheel canine tooth are taken turns in transmission two; The fixedly connected second axle in place, second wheel axle center.Concrete, the number of teeth of described rotor wheel is 8, the number of teeth that canine tooth is taken turns in transmission one is 32, the number of teeth that little tooth is taken turns in transmission one is 8, and the number of teeth that canine tooth is taken turns in transmission two is 40, and the number of teeth that little tooth is taken turns in transmission two is 8, the number of teeth of second wheel canine tooth is 48, and the number of teeth of the little tooth of second wheel is 7.
Its principle of work: the IC output signal is 4HZ, i.e. 4 signals of per second output, and it drives the rotor wheel per second and rotates 4 times, is that half-turn (design of stepper motor) is so under the situation that 4 signals drive, the rotor wheel per second just rotates 2 circles because the rotor wheel revolution makes a movement; Simultaneously, the per second rotor wheel is rotated 2 circles, so and second wheel must rotate 1/60 circle by per second. and the speed ratio that rotor takes turns to second wheel just is designed to 1/120. for realizing this purpose, just two power wheels of design between rotor wheel and second wheel.
8 teeth of rotor wheel
Little tooth 8
Little tooth 8
Second wheel canine tooth 48
Little tooth 7
The little tooth of second wheel (7 teeth) is to drive following minute wheel, hour wheel etc.
Speed ratio=8/32 * 8/40 * 8/48=1/120
Be rotor wheel under the driving of 4HZ signal, per second rotates 2 circle * 1/120=1/60, namely second wheel revolution moving 1/60 encloses, but it is second hand has moved situation under 4 in one second under, so look similarly to be to walk about continuously.
Described stepper motor comprises coil, coil former, stator piece, and coil stationary is in coil former, and stator piece is connected with rotor wheel magnetic.Coil former is fixed coil effectively, coil and wiring board weld together, and stator piece and coil former are the metal magnetic conducting material, can produce enough magnetic actions, magnetic principles about quartz vibration and stepper motor among the present invention is the common practise of this area, does not carry out detailed narration at this.
Further, movement also comprises bottom plate, stable being fixed together of whole device can have been prevented damage by bottom plate.
Compared with prior art, beneficial effect is: IC output signal of the present invention, quartz crystal produces vibration, stepper motor produces magnetic force and promotes the rotor wheel rotation, rotor wheel drives power wheel and rotates, power wheel drives second wheel and rotates, because second wheel, second axle, second hand three are fixed together, second hand rotates and is to rotate continuously; Its kind of drive is simple, assembles also comparatively easyly, and the engagement between the gear is tight, has realized that second hand rotates continuously, and its rotating effect is similar to stem-winder, therefore, has filled up the blank of electronic quartz watch on this rotating effect, and is more practical.
