Timepiece movement is difficult to largely produce because of technology and Cost Problems.In order to meet the different consumer group of in the market, it is necessary to which one kind has concurrently
Automation table balance spring shakes the advantages of accurate aesthetic feeling and low quartz watch punctual timing cost of system in the hand of one
Table movement.But the oscillating circuit how automation table balance spring is shaken to system and quartz watch combines, shape
The product module new into one, technical difficult points are both each own signal sources, and balance spring concussion system is mechanical letter
Number, there is the fixed vibration period, forms of motion is reciprocating rotation, and quartz watch is then after electric signal is first changed into magnetic signal
It is changed into mechanical signal output again, and forms of motion is single direction rotation.Therefore, how to be driven and put using going barrel energy accumulation
Take turns the complicated mechanical structure of hairspring concussion system conventional, the cycle of two signal sources is unified, and forms of motion is unified
To solve the key point of problem.

Embodiment
With reference to embodiment, technical scheme is described in further detail, but not formed pair
Any restrictions of the present invention.
Referring to figs. 1 to shown in 3, a kind of oscillating structure by electric energy conversion and control balance spring oscillatory system of the invention,
Including movement bottom plate 1 and the balance spring oscillatory system 2 being arranged on movement bottom plate 1, wherein, in described movement main folder
Driving system of stepping motor 3 is additionally provided with plate 1, the driving system of stepping motor 3 drives balance spring oscillatory system 2 to swing.
Mechanical signal output is converted the electrical signal to using driving system of stepping motor 3, driving balance spring oscillatory system 2 is swung, with
The oscillating circuit perfect adaptation that automation table balance spring is shaken to system and quartz watch is realized, can also be by other auxiliary
Help train to export to pointer, complete timing purpose, timing is more accurate, and cost is lower, and processing and fabricating is easier, and structure is new
Grain husk, product are attractive in appearance.
The signal period of the driving system of stepping motor 3 is identical with the cycle of oscillation of balance spring oscillatory system 2.According to
The present situation of domestic product mechanical watch at present, the swing intrinsic frequency overwhelming majority of used balance spring oscillatory system 2 are
3Hz, it is most suitable as mechanical vibration source that selection swings balance spring oscillatory system 2 of the intrinsic frequency for 3Hz.If it is intended to make pendulum
Take turns hairspring and produce continual vibration, it is necessary to have the signal source of identical vibration frequency as energy supplement, that is, set stepper motor
Output frequency 3Hz, will so produce resonance.
Described balance spring oscillatory system 2 includes the balance wheel assembly 21 with rotary inertia, hairspring component 23 and pendulum folder
Board component, described one end of balance wheel assembly 21 connect with coaxial fasten of p-m rotor 31.Driving system of stepping motor 3 includes permanent magnetism
Rotor 31, stator piece 32, driving chip and the coil windings 33 being connected with stator piece 32, described p-m rotor 31 and escapement
The balance wheel assembly 21 of hairspring oscillatory system 2 coaxially fastens connection.By the signal period of driving system of stepping motor 3 and balance spring
After the rotation period of oscillatory system 2 is set, described driving system of stepping motor 3 driving balance wheel assembly 21 rotates, and works as pendulum
After wheel assembly 21 overcomes the opposing torque of hairspring component 23 to rotate certain extreme angles, an extreme position is reached, then in hairspring
Component 23 matches p-m rotor 31 and turned round under the effect of the righting moment of hairspring component 23.Under moment of inertia effect, through overbalance
Behind position, driving system of stepping motor 3 drives balance wheel assembly 21 to be rotated to other direction, when balance wheel assembly 21 overcomes hairspring component
After 23 opposing torques rotate certain extreme angles, another extreme position is reached, then matches p-m rotor in hairspring component 23
31 the righting moment of hairspring component 23 effect under reversed turning.Now the moment of inertia of hairspring component 23 is larger, by balance position
Postpone, driving system of stepping motor 3 sends drive signal again, repeats above-mentioned action, principle also as described above, so week and
Renew, balance spring oscillatory system 2 is issued to resonance in the driving of the power of driving system of stepping motor 3, and the amplitude of oscillation is gradually increased, directly
To dynamic equilibrium.
According to the operation principle of stepper motor, the p-m rotor 31 of driving system of stepping motor 3 is formed in driving chip to be handed over

The reciprocating rotary of 2 identical cycle of oscillation of system, the pulse current of driving system of stepping motor 3 is as shown in figure 4, wherein, stepping is electric
The output of machine drive system 3 is the bidirectional pulse signal of alternately change, and pulse width is 2.9~15.6ms, operating voltage 1.0
~3.0V, output frequency 3Hz.
Only when torque caused by p-m rotor 31 is more than or equal to the elastic force location torque ability of hairspring component 23
Rotation is realized, after the pulse current for now setting driving system of stepping motor 3, the location torque that makes p-m rotor 31 is zero (to go
Fall stator piece 32 and produce the uneven factor of magnetic gap), and location torque is replaced with the moment of elasticity of hairspring component 23, if escapement
If hairspring oscillatory system 2 is acted on by turning moment once to be started, and signal continually produces resonance, then balance spring shakes
The hairspring component 23 swung in system 2, which will constantly shrink, -- to be recovered -- to extend and -- recover -- to shrink -- recover -- extending again -- again
Recover, constantly vibration is gone down, until reaching dynamic equilibrium, while drives p-m rotor 31 to reach with driving system of stepping motor 3
The intrinsic rated frequency of identical, it is possible to so that balance wheel assembly 21 is vibrated with specified frequency, make its pendulum with traditional mechanical watch
It is identical with effect to take turns the mode of oscillation of hair spring system, has been also equipped with the product aesthetic of the balance and hair spring system of traditional mechanical watch.
Described driving system of stepping motor 3 is connected with timepiece movement power supply, is stepping electricity using the power supply of timepiece movement
Machine drive system 3 provides electric signal.
It the foregoing is only the preferred embodiment of the present invention, all timess made in the range of the spirit and principles in the present invention
