Definitions
- FIG. 3 of the aforementioned CH 597 636 patent schematically illustrates a variant which corresponds to the preamble above, that is to say in which the part rotating electric generator driven by the spring of the watch movement is constituted by the pendulum of a clock resonator of the spiral-balance type.
- the generator rotor of the basic version is replaced by a oscillating element which is the pendulum.
- This one carries two juxtaposed magnets having mutually inverted polarities and passing opposite an induction coil fixed during the oscillation of the pendulum.
- no construction of such pendulum generator is proposed in this patent and has not been realized since then, Our knowledge.
- a particular problem that arises in such a generator to watch pendulum lies in the configuration of the magnetic circuit ensuring the coupling between the fixed coil and the pendulum magnets, taking into account the neighboring metal masses of the mechanical clockwork movement.
- Another kind of combination of a mechanical watch movement with an electromagnetic control device is the subject of a group of patent applications of Seiko Instruments Inc., including applications EP 1 093 036 and EP 1 143 307, and comprises a multipole annular magnet, mounted on the balance and cooperating with one or more fixed induction coils. These are connected by lead wires to a switching mechanism located on the cock and operating by contact with the hairspring depending on the amplitude of oscillation of the balance. This contact shortens the coils to brake the balance when the amplitude of oscillation exceeds a predefined threshold. These reels are placed on the platinum of the movement, opposite the balance beam serge. In a construction described in the application EP 1 143 307, they are grouped on a map printed circuit board to form an electrical circuit unit which is installed at a location arranged for this purpose on the plate.
- Such an arrangement does not have the function of producing energy electric, but only to lose energy to the pendulum, we do not attach importance to energy conversion efficiency, or to the configuration of the magnetic circuit.
- the presence of platinum and other elements of the movement in the vicinity of the induction coils is not a problem in this area. application, whereas it may be so when it comes to ensuring, in the case of this invention, feeding an electronic oscillator consuming the least possible mechanical energy provided by the spring.
- An object of the invention is to produce a timepiece of the type indicated in preamble by arranging the electronic regulator in a way that allows to use a mechanical clockwork movement with the least possible modifications, while ensuring effective electromagnetic coupling between the fixed and the moving part of the electric generator.
- An additional goal is to arrange the electronic controller in a space-saving form and allowing, if possible, place it in a box of the same size as a box intended to receive only the mechanical movement.
- a basic characteristic of a timepiece according to the invention lies in the fact that the electronic regulator is formed by a module completely separate from the mechanical clockwork movement. According to the case, this module can be fixed on a plate of said movement, or on the contrary be supported by the box independently of said movement.
- the electronic regulator comprises a printed circuit board carrying at least the rectifier, a quartz resonator and the servo circuit, and preferably also the coil. So, the electronic regulator is formed by an autonomous and completely separate structure mechanical movement, all but the coil can be outside mechanical movement. For example, this module can be attached to a circle casing that surrounds the mechanical movement. This makes it easy to mount the electronic module in a watch case after the casing of the movement mechanical.
- FIGS. 1 to 5 represent schematically the main elements of a wristwatch according to the invention, in a first embodiment.
- the watch includes a watch movement mechanical 10 self-winding, of a common type such as caliber Eta 2824, and an electronic regulator realized in the form of a module 11 comprising a coil 12 which cooperates by coupling electromagnetic with the balance 13 of the mechanical movement 10, this pendulum being the only piece modified compared to the original movement.
- the movement 10 is well known, only a few of its components in the drawings, in particular a spring-loaded barrel 14 which drives an escape wheel 15 via a wheel 16 comprising a wheel central second 17, from which is derived the drive of the hands 18 of the watch.
- the escapement comprises an anchor 19 giving pulses to the regulator 20 which comprises the rocker 13 and a spiral spring 21, the regulator being rotatably mounted between the plate 22 of the movement 10 and a cock 23 fixed to the platinum.
- the cock 23 is shown transparent to clarify the drawing.
- the plate 22 ( Figure 4) of the movement 10 is located in the box on the side of the dial 24 and is fixed by flanges 25 to a circle casing 26 which surrounds the movement 10 and which is mounted itself inside of the middle 27 of the watch box. So the rooster 23 and the other bridges of the movement 10, as well as the oscillating weight 28 of the automatic winding, located on the side of the removable bottom 29 of the watch case.
- the top of the box is formed by an ice 30 mounted on the middle part 27, either directly or by through a telescope.
- the movement 10 is designed to operate with a usual frequency oscillation of the regulator 20, the usual frequencies being generally understood between 2.5 Hz and 5 Hz, and preferably equal to 3 Hz or 4 Hz. In the examples Here, the theoretical oscillation frequency of the regulator 20 is 4 Hz.
- FIG. 2 represents in more detail the balance 13, seen from the side of the cock 23.
- balance wheel comprises an axis 32 whose ends are mounted in bearings carried by the plate 22 and the cock 23, and a flat wheel having a serge 34 provided with two enlarged portions 35 and 36 each centered on a diametral axis 37 of the wheel of balance.
- Part 35 carries two magnets 38 and 39, while part 36 is a counterweight so that the center of gravity of the pendulum is at the center of its axis 32.
- Each of the magnets 38 and 39 is formed by a small cylindrical pellet magnetized parallel to the axis 32 of the balance, but with opposite polarities of a magnet to each other in order to create field lines that pass through both magnets.
- the magnets are fixed on the part 35 of the serge, for example by gluing, on the opposite side to the plate 22.
- the strut 34 of the balance is made of a metal magnetic such as iron-nickel, so that its part 35 forms a magnetic shunt which closes the magnetic field circuit created magnets 38 and 39 on the side of the platinum 22.
- the balance 13 may have approximately the same external dimensions and the same mass.
- the thickness of the serge 34 may be 0.15 mm and that of the magnets of 0.25 mm, so that the total thickness of 0.4 mm is the same as that of the serge the balance of the original movement.
- the mechanical regulator 20 is arranged to have a slightly higher natural oscillation frequency (for example about 1%) than the theoretical frequency of 4 Hz over the entire useful range of the winding of the spring 54, so that the stabilization of its real frequency by the circuit servo can be done only by small braking pulses. AT this effect, a simple solution is to use a spiral identical to that of the original movement and give the pendulum a moment of inertia slightly inferior. It is also possible to adjust the advance of the mechanical regulator in the manner classic, by means of the racket.
- the mechanical regulator 20 is mounted so that, in its neutral position where the hairspring 21 is at rest, the diametral axis 37 and therefore the pair magnets 38 and 39 are opposite the coil 12.
- the pendulum 13 oscillates on either side of this neutral position as indicated by arrows A and B in Figure 2.
- the instantaneous speed of the pendulum is maximum when it passes through its neutral position, the effective voltage induced in the coil will be maximized if the pair of magnets passes in front of the coil at that time.
- the amplitude oscillation of approximately ⁇ 270 degrees when the barrel spring is fully armed in a traditional movement can here be somewhat reduced, for example to about ⁇ 180 degrees, by the power consumption of the electric generator.
- FIG. 3 shows the external appearance of the electronic module 11, whose circuits will be described later with reference to Figure 6. Its components are supported by a circuit board 41 having a generally segmental shape of a circle, so as to take place against the underside of the casing ring 26, to which it is fixed by screws 42.
- the components shown in FIG. comprise the coil 12 mounted on a portion 43 of the card 41 widened in the direction from inside the watch, a pair of Schottky diodes 44 and 45, a pair of capacitors 46 and 47, a crystal resonator 48 and an integrated circuit 49.
- the coil 12 is mounted on the upper face of the card 41, which holds it in a fixed position which is chosen so that there is a small gap between the coil 12 and magnets 38 and 39, typically of the order of 0.2 mm to ensure coupling electromagnetic enough strong.
- the other elements 44 to 49 are mounted on the underside of the card 41, so that they are in a space 50 usually free between the casing ring 26 and the bottom 29 of the box.
- these elements or some of them could also be on the upper face of the card 41, provided that clearances appropriate in the casing ring 26.
- the coil 12 could be mounted on a separate support instead of being directly on the map 41. This could then be replaced by a flexible film, which could be glued under the casing ring 26.
- the configuration of the electronic module 11 can accommodate this module in the watch case entirely outside the mechanical movement 10, with the exception of the spool 12 which must be in front of the balance rod 13.
- this coil occupies a space which, in the usual mechanical movements, is generally free between the hairspring 21 and the periphery of the movement. In some types of self-winding movements, this space may be partially occupied by the thick peripheral part of the oscillating mass 28. If one wishes use the present invention with such a movement, it will be enough to slightly modify this part of the oscillating mass so as to release a sufficient height for the reel 12. Such a change is easy and does not affect the others components of the movement, provided that the change of the oscillating weight not decrease the winding torque.
- the box of the watch can be identical to that who receives the original mechanical movement.
- the circuits of the electronic module 11 described above are represented in FIG. FIG. 6 and comprise the coil 12, a rectifier 58 and a servocontrol circuit 60 which is realized in the integrated circuit 49 shown in FIG. 3.
- the rectifier 58 comprises the two Schottky diodes 44 and 45 and the two capacitors 46 and 47, which are preferably of the ceramic type.
- the rectifier inputs are connected at the terminals of the coil 12 and its outputs V +, V0 and V- provide power to the servo circuit 60 thanks to the electrical energy produced by the generator 56 and stored in both capacitors.
- a minimum value of 0.6 V of the voltages V + and V-, corresponding to the minimum allowable amplitude of the oscillation of the balance 13 is sufficient to operate the integrated circuit 49, in particular if it is realized in SOI technology.
- the timing diagram (a) of FIG. 7 shows the evolution of the voltage Ug induced at the terminals of the coil 12 by three alternations of the balance 13, each alternation comprising a passage of the pair of magnets 38 and 39 in front of the coil.
- the first pass during the movement of the balance in a first direction, successively generates three main alternations of the voltage Ug, namely a negative alternation A1, a positive half cycle A2 and a negative half cycle A3, then the tension remains substantially zero while the movement of the balance ends and changes direction. Interruption of voltage for a short time tf corresponds to a braking which will be described later.
- the servocontrol circuit 60 comprises an oscillator referenced Osc, driven by the quartz resonator 48 to form a time base. Circuit 60 is arranged to control the oscillation frequency of the balance 13 at a frequency of FR derived from the Osc oscillator, performing brief operations of braking of the balance by shorting the coil 12 by means of a electronic switch such as a transistor 62, according to the principle described in the patents EP 679 968 and EP 806 710 mentioned above. Since the circuit 60 shown in Figure 6 is substantially similar to that described in patent EP 806 710 (corresponding to US Pat. No. 5,740,131) to which the reader will be able to refer for more details, it will be described here in a simplified way, all explaining in detail the differences resulting from the present invention.
- An output of timer Tmr delivers, when necessary, a braking pulse IF of duration tf, which makes the driver the transistor 62 to short circuit the coil 12.
- the voltage Ug falls to a value close to zero, as can be seen in the chronogram (a) of the figure 7.
- the voltage Ug across the coil 12 is delivered to means of measuring its frequency, including a Schmitt trigger referenced Trig and a inhibition circuit Inh.
- the Trig flip-flop delivers to the inhibition circuit an IM detection signal which changes sign whenever the absolute value of the voltage Ug rises enough to cross the high Uth or low Utb voltage threshold of the flip-flop.
- the role of the inhibition circuit Inh is to deliver, for each period of the oscillation of the balance 13 and therefore for a passage on two of the pair of magnets 38 and 39 opposite of the coil 12, a measurement pulse IN at the positive input of the comparator circuit Cmp and timer Tmr.
- the measurement pulses IN represented in the timing (c) of Figure 7, therefore theoretically have a frequency f of 4 Hz and a period T of 250 ms, but one can also envisage to deliver a pulse of IN measurement for each passage of the magnets in front of the coil, so at a theoretical frequency of 8 Hz.
- the circuit inhibition Inh is arranged not to consider the first change of state of the IM signal at time t1 shown in Figure 7, but only the second at time t2, to deliver the measuring pulse IN. Otherwise, we could also consider braking during the first alternation A1.
- the function of the comparator circuit Cmp is to indicate by its output signal AV if the oscillation of the balance 13 is in advance compared to that of the oscillator CSOs.
- This comparator can be for example a down-counter or counter reversible, which totals the difference between the number of measurement pulses IN received at its positive input and the number of reference pulses received at the frequency FR at its negative input.
- the Tmr timer receives the AV signal and, if this indicates that the balance is in advance, it delivers a brief braking signal IF which temporarily turns on the transistor 62, which brakes the balance as it has been explained above.
- the start of the IF braking signal is preferably slightly delayed compared to the appearance of the measurement pulse IN, as see it in FIG.
- the duration tf of the braking signal IF is predetermined by way that the braking takes place in an initial part of the greater alternation A2 of the voltage Ug, but not in the duration where the voltage is the highest, because it is at this moment that the electric generator 56 can provide the most energy to capacitors 46 and 47.
- the timer Tmr begins to deliver to the circuit Inh a muting signal IF having function to prevent the transmission of another IN measurement pulse before the next swing period of the pendulum.
- the duration t i of the inhibition signal S i is a little shorter than the period T, for example 80% of T.
- FIG. 8 is a sectional view similar to FIG. 4 and represents a second embodiment of a watch according to the invention, which will be described only differences from the example described above, by reusing the same reference numbers for the corresponding elements.
- the card printed circuits 41 of the electronic module 11, instead of being placed against the face bottom of the casing ring 26, is on the upper face of this circle, that is to say on the side of the dial 24.
- the coil 12 and the other components mounted on the card 41 are placed on the underside of the card, said components taking place in recesses (not shown) formed in the casing ring 26.
- An insulating sheet may be interposed between this circle and the map in the zones where the card is attached to the circle by the screws 42.
- the operation of the watch is the same as in the first embodiment.
- the pendulum 13 differs from that of the previous example only by the fact that the magnets 38 and 39 are placed on the upper face of the serge, to pass near the coil 12 located above. Depending on the original movement used, it can it is necessary to make a cut-out 52 in the plate 22 to make room for the coil 12. This can be done in general without difficulty, because if the platinum of Usual movements extends in this region, it is only to shoulder the dial and she usually does not carry any component of the movement itself.
- the only modifications to be made on the mechanical watch movement 10 consist in changing the pendulum and to may possibly cut 52 in the plate. No change is required on the oscillating weight 28 of the automatic winding.
- the casing ring 26 will obviously have to be adapted to receive the electronic module 11.
- the box of the watch may be identical to that which receives the original mechanical movement.
- the cut 52 may be replaced by a recess occupying only a portion of the thickness of the platen.
- Platinum fixation has the advantage of ensuring a high positioning precision of the coil 12 by compared to pendulum 13.
- the applications of the present invention are not limited to this object and extend to any type of timepiece having a movement mechanical provided with a balance-sprung regulator.
