Description
Technical field
The utility model relates to clock field, relates in particular to a kind of clock and watch and movement thereof.
Background technology
To modern society, the development of clock and watch has brought earth-shaking life to change to people from the social development in time immemorial.In 1088 Christian eras, the scientist Su Song of China Song dynasty and Han worker are honest and clean etc., and the people made the water transport instrument resembles platform, and it is the device that armillary sphere, celestial globe and mechanical timer are combined.It as power resources, has the escapement of science with waterpower, and high about 12 meters, seven meters square, and divide three layers: armillary sphere is put on the upper strata, carries out astronomical sight; Celestial globe is put in the middle level, can simulate celestial body and do demonstration synchronously; Lower floor is the heart of this instrument, timing, give the correct time, the formation of power source and output is all in this one deck.Though be destroyed in chaos caused by war after decades, it is extremely important on the universal clock history, is first clock and watch in the world.Passed through the development of several centuries afterwards, it is more and more littler that clock and watch become, also more and more accurate when walking.Gone out more and smaller and more exquisite mechanical clock, electronic watch and the quartz clock of profile at modern age society evolving development.
Mechanical clock is that the gravity that utilizes the recovery of band spring to be out of shape the energy of being emitted or to utilize weight to descend is made the energy, is time reference with the mechanical vibrating system, realizes the mechanical mechanism of metering time and period.There is polytype in mechanical clock mechanism, but generally all by former moving system, power train, escapement speed regulating system, go up that bar is dialled pin system and minute hand system is formed.Also comprise in the mechanical watch of auomatic fixing chain and go up bar mechanism automatically.
Electronic watch is generally digital lcd and shows that it utilizes the electricity oscillation principle.Oscillatory circuit the earliest is to be made of inductor and capacitor, is called lc circuit, but its frequency stability is not very good, damages easily.Afterwards, scientists replaced the LC oscillator with quartz crystal, had just improved frequency stability greatly.Quartz is the hexagonal crystal of rule.Be called quartz wafer by the thin slice under the orientation cutting on the quartz crystal.Quartz wafer has a marvellous characteristic: if mechanical force in addition on the wafer then will produce electric field on corresponding direction.This physical phenomenon is called ＂ piezoelectric effect ＂.On pole plate, connect AC field at quartz wafer.When the frequency that adds alternating voltage equates with the natural frequency of quartz wafer, will produce resonance.This phenomenon is called ＂ piezoelectric resonant ＂.Utilize this stable oscillating characteristic, people have just createed the high quartz clock of precision.The quartz clock punctual timing, in light weight and the maintenance be easier to; But aesthetic property and innervation are not as good as mechanical clock.Therefore, existing clock and watch are not accurate enough when walking, and are attractive in appearance inadequately and do not have an innervation when just being to use.
In summary, existing clock and watch structure exists inconvenience and defective on reality is used, so be necessary to be improved.
