Description
The present invention relates to electronic watch, wherein the energy is that generator by continuous rotation constitutes, and this generator is driven by an artificial or automatic going barrel spring mechanism.
In such clock and watch, going barrel mechanically drives indicator and the generator of instruction time simultaneously, and generator itself has two kinds of functions.At first it is the circuit working power supply under the help of the time reference that is preferably formed by quartz.Second function of generator comprises the adjuster as clock and watch, so that the rotary speed of indicator remains on the numerical value of regulation.
An example of such clock and watch is disclosed in the European patent EP-0239820.Here 1 repeat following its operation principle simply with reference to the accompanying drawings.
These clock and watch 1 comprise a going barrel 2, and a spring 3 wherein is installed.The latter can make it to wind up with a mechanism that winds up, and this mechanism that winds up is very familiar to the watchmaker, both can be artificial, also automatically, is used in usually in the so-called stem-winder.
Going barrel 2 is by a gear train 6 and indicator 4 and generator 5 couplings that schematically shows with dotted line in the accompanying drawings according to the present invention.
Generator 5 is designed to alternating voltage on end points G1 and G2, and said voltage is connected with the side circuit of a buffer condenser 8 and table by in addition rectification of a rectifier 7 at its output.
In order to adjust the work of indicator 4, generator 5 is with constant speed, and for example the speed of per second 4 commentaries on classics is being rotated enduringly.Provide adjustment circuit 10, one frequency standard oscillators 11 as a quartz to be attached thereto for this reason.Adjusting circuit 10 can compare the frequency of the alternating voltage that produced by generator 5 with the frequency that is produced by frequency standard oscillator 11.If comparative result show generator rotate too fast (frequency of its output voltage is too high), this adjusts circuit with a control signal, outputs on the control line 12.
At the two ends of generator 5, can connect a short-circuit resistance 13 by a switch 14 of being controlled by control signal.When under the control of switch in control signal when closed (the generator rotation is too fast), in fact resistance 13 make the generator coil short circuit.So just slowing down, the latter comes back to needed speed up to it.
This adjustment process has complete explanation in above-mentioned European patent.But the accuracy that should remember the work of showing depends on the accuracy for the frequency measurement of generator 5 both end voltage to a great extent.This measurement is to finish by the intersection that detects this voltage.
The accuracy of having seen this clock and watch is not very good.In fact, can't measure the moment that the voltage that produced by generator intersects with desired precision, therefore, what only write down time cycle of separating these moments is not that unsubstantiality changes.
This inaccurate reason so people try to find out, and the output voltage that has been found that generator comprises a residual components in an irregular mode, though this component is very little, but fairly obvious, it makes intersection moment of output voltage randomization that becomes.Therefore, in the alternating sequence-changing of this output voltage, intersecting moment just may be fast randomly or slow.
Its reason be generator coil not only to produce by generator magnet, by their the variation sensitivity in magnetic field, and responsive too for the variation in external magnetic field such as magnetic field of the earth.Therefore, the voltage of generator output end may comprise the component that a comparison can not be ignored, this component continues to exist in generator output end, even because generator magnet is also like this when making that with respect to the position of its coil generator output voltage is zero substantially.
The purpose of this invention is to provide a kind of generator that is used for clock and watch, it can overcome adjusting aspect the generator work correct of existing in the prior art, thereby in the defective of adjusting aspect the watchmaking.
