Definitions

  • a timepiece having these characteristics which is described for example in patent US-A-3937001, has the same precision as a conventional electronic timepiece thanks to the fact that the reference pulses, the frequency of which determines the rotational speed of the generator rotor and therefore that of the current time display hands, are produced from a signal supplied by a quartz oscillator.
  • this timepiece does not have a battery or accumulator since the power supply to its electronic circuits is ensured by the electrical energy supplied by its generator, the rotor of which is connected to its source of mechanical energy, which is constituted by a barrel spring similar to that used in classic mechanical timepieces.
  • the braking means of the generator rotor consist of a resistor connected in series with an electronic switch, the assembly formed by this resistor and this switch being connected in parallel with the generator coil.
  • this switch is controlled directly by the comparison signal so as to be permanently closed when the latter is in its first state, that is to say as long as the generator rotor is ahead of the position. that it would occupy if it had always been running at its set speed.
  • the electronic circuits of the timepiece are supplied by a direct voltage supplied by a rectifier circuit of the alternating voltage produced by the generator.
  • the electronic circuits of the timepiece could be supplied, during these braking times, by the electrical energy accumulated in the capacitor (s) that generally comprises the rectifier circuit supplying these circuits, even if the value of the braking resistor was zero.
  • the generator rotor can be braked without interruption for a fairly long time. It is therefore practically excluded to choose a zero value for the braking resistor, because the capacitor of the rectifier circuit should then have a very high capacity and should therefore be quite bulky and expensive. It would also not be possible to determine with certainty the capacity that this capacitor should have since the maximum time during which the generator rotor can be braked cannot be predicted in advance.
  • the braking resistor When the braking resistor is connected in parallel with the generator coil, the alternating voltage produced by this coil is reduced on the one hand because of the reduction in the speed of rotation which results from this connection and, on the other hand, because of the voltage drop produced in the generator coil by the current absorbed by the braking resistor.
  • the braking torque applied to the generator rotor is higher the lower the value of the braking resistor, this braking torque being maximum when this braking resistor has a zero value.
  • This braking torque must obviously impose on the generator rotor a rotational speed lower than its set speed whatever the engine torque supplied by the barrel spring.
  • this engine torque can be as high as possible, which favorably influences the autonomy of the timepiece, that is to say the time during which it can operate without its barrel spring must be reassembled, so the braking torque must also be high, which implies that the braking resistor has a low value.
  • this resistance should have a zero value.
  • the braking resistor of the rotor must therefore fulfill two contradictory conditions. On the one hand, it must be sufficiently high, and in any case not zero, for the supply voltage of the electronic circuits to be sufficient in all circumstances. On the other hand, it must be low enough, and preferably zero, for the braking torque to be high and for the rotational speed of the rotor, when it is braked, to be lower than its set speed even when the torque motor supplied by the mechanical power source is maximum.
  • a coil having a large number of turns of a small diameter wire has a high internal resistance which, on the one hand, adds to the braking resistance and reduces the braking torque of the rotor and, on the other hand, causes a decrease in the alternating voltage produced by the generator when it is traversed by the current supplied by the latter.
  • An object of the present invention is to provide a timepiece of the same kind as that described in patent US-A-3,937,001 already mentioned but which does not have the drawbacks thereof, that is to say ie a timepiece in which the value of the rotor braking resistance can be very low, or even zero, without it being necessary to give the generator coil a high number of turns and without there is a risk that, in any circumstance whatsoever, the supply voltage of the electronic circuits will become insufficient for the latter to function correctly.
  • this very low, or even zero, value of this braking resistor makes it possible to choose the barrel spring driving the generator rotor so that its maximum torque is high and the autonomy of the timepiece is therefore higher, all other things being equal, than that of the known timepiece mentioned above.
  • the timepiece according to the present invention which is designated by the general reference 1
  • This barrel spring, designated by the reference 2 has only been shown very schematically because it can be of the same kind as any of the well known barrel springs which are used in conventional mechanical timepieces.
  • This barrel spring 2 is coupled to a manual or automatic winding mechanism which has not been shown because it can be similar to any of the well-known winding mechanisms which are also used in conventional mechanical timepieces .
  • the barrel spring 2 is mechanically coupled to the rotor 3a of an electrical energy generator 3 via a gear train 4 symbolized by a dashed line.
  • This generator 3 also includes a coil 3b, and it will not be described in detail since it can be produced in various ways well known to specialists.
  • the rotor 3a comprises a bipolar magnet which has been simply symbolized by an arrow representing its axis of magnetization.
  • the coil 3b is magnetically coupled to the permanent magnet of the rotor 3a, for example by means of a stator which has not been shown, so as to produce between its terminals B1 and B2, in response at any rotation of the rotor 3a, an alternating voltage Ug whose period is equal to the period of rotation of the rotor 3a, that is to say the time taken by this rotor 3a to make a revolution.
  • the terminals B1 and B2 of the coil 3b obviously constitute the output terminals of the generator 3.
  • the timepiece 1 also includes a rectifier circuit 5 whose inputs 5a and 5b are respectively connected to the terminals B1 and B2 of the generator 3 and whose outputs 5c and 5d provide a voltage Ua at least substantially continuous in response to the alternating voltage Ug produced by the generator 3.
  • This voltage Ua is intended to supply the various electronic circuits which will be described later by means of conductors which have not been shown.
  • the rectifier 5 will not be described in detail since it may be similar to any of the rectifiers well known to specialists. It will simply be mentioned that this rectifier 5 comprises, conventionally, a filtering capacitor which is connected between its output terminals 5c and 5d and which has not been shown.
  • the terminals 5a and 5c of the rectifier 5 are connected to each other as well as to the terminal B1 of the generator 3. Furthermore, the potential of these three terminals 5a, 5c and B1 has been chosen arbitrarily as the reference potential , or mass, and all the voltages which will be mentioned in the remainder of this description will be voltages measured with respect to this reference potential.
  • the alternating voltage Ug is therefore symmetrical with respect to this reference potential when the rotor 3a rotates at constant speed.
  • the timepiece 1 also comprises means for displaying the current time which are constituted in this example by conventional hands, designated by the reference 6, but which can also be constituted by other well known elements such as records, drums or the like. It can also include one or more annex display devices such as a calendar, moon phase or other device. Such an additional device has not been shown.
  • the needles 6 and, where appropriate, the accessory device (s), are mechanically connected to the barrel spring 2 and to the rotor 3a of the generator 3 by means of a gear train, at least part of which may be common with part of the train 4.
  • this gear train connected to the needles 6 has not been referenced separately, and it is also symbolized by a dashed line.
  • the timepiece 1 also includes a mechanism for setting the time of the hands 6 and, if necessary, for correcting the accessory device (s), which has not been shown because it can be similar to any one various mechanisms of this kind which are well known to specialists.
  • control circuit 7 which determine the speed of rotation of the rotor 3a and which will be described later, as well as the gear train 4, are arranged so that the needles 6 rotate at their normal speeds when the rotor 3a rotates at the set speed Vc. It will be assumed that, in the present example, this reference speed Vc has been fixed at 4 revolutions per second.
  • the characteristics of the barrel spring 2 and of the various elements which it drives, as well as the characteristics of the generator 3, are chosen so that the average speed of rotation of the rotor 3a is greater than the set speed Vc as long as the barrel spring 2 is not almost completely disarmed, provided that the coil 3b is not short-circuited.
  • these characteristics are chosen so that this average speed of rotation is less than this reference speed Vc if the coil 3b is short-circuited, under circumstances which will be described later, even when the barrel spring is completely wound up and the engine torque it provides therefore has its maximum value.
  • the servo circuit 7 mentioned above comprises a comparator 8 whose direct input is connected to the terminal B2 of the generator 3 and whose reverse input is connected to the reference potential, so that the signal produced by its output , which will be called signal SM in the following description, is alternately in state “0" and in state “1" depending on whether the voltage Ug supplied by generator 3 is negative or positive.
  • the period of the signal SM is obviously equal to that of the voltage Ug so that, in particular, this period of the signal SM is 250 milliseconds when the rotor 3a of the generator 3 rotates at its set speed Vc which is 4 revolutions per second in this example.
  • the signal SM passes from its state "0" to its state “1" each time the rotor 3a of the generator 3 passes through a determined angular position, which is that at which the voltage Ug passes through its increasing zero value. .
  • the signal SM is therefore both a signal for measuring the speed of rotation of the rotor 3a and a signal for detecting the passage of this rotor 3a through the determined angular position defined above.
  • the servo circuit 7 also comprises a source of a reference signal SR, constituted, in this example, by an oscillator 9, which can be a quartz oscillator, and a frequency divider circuit 10 having an output Q1 which provides the signal SR in response to the signal produced by the oscillator 9.
  • a source of a reference signal SR constituted, in this example, by an oscillator 9, which can be a quartz oscillator, and a frequency divider circuit 10 having an output Q1 which provides the signal SR in response to the signal produced by the oscillator 9.
  • This oscillator 9 and this frequency divider 10 will not be described in detail since they can be produced in various ways well known to those skilled in the art. It will simply be mentioned that this oscillator 9 and this frequency divider 10 are arranged so that the period of the signal SR is equal to that of the signal SM when the rotor 3a of the generator 3 rotates at its speed of setpoint Vc, that is to say 250 milliseconds in the present example.
  • the frequency divider 10 has a second output, designated by Q2, providing a signal SC having a much shorter period, for example of the order of a hundred times shorter, than that of the signal SR, and whose l the usefulness will be made evident later.
  • this signal SC can be supplied by the output of the sixth flip-flop of the frequency divider 10 and thus have a period equal to approximately 1.95 milliseconds.
  • the servo circuit 7 also includes a reversible counter, or up-down counter, which is designated by the reference 11.
  • the counting input C of this counter 11 is connected to the output Q of the frequency divider 10 and therefore receives the signal SR, and its down counting input D is connected to the output of comparator 8 and therefore receives the signal SM.
  • This reversible counter 11 will not be described in detail since it can be produced in various well known ways. It will simply be specified that it is sensitive to the rising edges of the pulses it receives, that is to say to the passages from logic state "0" to logic state "1" of signals SR and SM. In other words, the content of this counter 11, that is to say the binary number formed by the logical states “0” or “1” of the direct outputs of the various flip-flops which form it, is increased by one unit on each rising edge of the SR signal pulses and decreased by one unit on each rising edge of the SM signal pulses.
  • This counter 11 comprises in in addition to well-known means which make it possible to remove any ambiguity due to any superposition in time of the pulses which it receives on its inputs C and D.
  • the counter 11 has an input R for resetting to zero and it is arranged so that its content is maintained at the value zero as long as this input R is in the logic state "1".
  • the counter 11 is made up of n flip-flops, its content can take any value greater than or equal to zero and less than or equal to 2 n -1.
  • the operation of the counter 11 is cyclic, that is to say in particular that, when its content is equal to zero, this content takes the value 2 n -1 in response to a pulse applied to its down counting input D .
  • positive values of the content of counter 11 will be called those which are greater than or equal to zero and less than or equal to 2 (n-1) , and negative values of this content those which are greater than 2 (n-1) and less than or equal to 2 n -1.
  • the output Q of the counter 11 which is conventionally constituted by the direct output of the last of its flip-flops, is in the logical state "0" when the content of counter 11 is positive and in logic state "1" when this content is negative.
  • the output Q of the reversible counter 11 is connected to a first input of an AND gate 12, the second input of which is connected to the output of the comparator 8.
  • This gate 12 is connected to the input S of a flip-flop 13 of type R-S whose input R is connected to the output of an OR gate 14.
  • the flip-flop 13 is sensitive to the rising edges of the pulses it receives on its inputs S and R.
  • the direct output Q and the inverse output Q ⁇ of this flip-flop 13 respectively take the logic state “1” and the logic state “0” in response to each rising edge of the signal applied to its input S, and respectively take the logic state "0” and the logic state "1” in response to each rising edge of the signal applied to its R input.
  • a first input of the OR gate 14 is connected to the output Q of a simple, non-reversible counter 15.
  • This counter 15 consists in this example of five flip-flops connected in series in a conventional manner so that its output Q, which is the direct output of its fifth flip-flop, goes from state "0" to state "1" when its content changes from the value fifteen to the value sixteen.
  • the counting input C of the counter 15 is connected to the output Q2 of the frequency divider 10 and therefore receives the signal SC, and its reset input R is connected to the inverse output Q ⁇ of the flip-flop 13.
  • the counter 15 is sensitive to the rising edges of the signal applied to its counting input C, and its content is maintained at the value zero as long as its input R is in logic state "1".
  • the servo circuit 7 further comprises means for electrically braking the rotor 3a of the generator 3, which are constituted in the present example by an n-type MOS transistor, designated by the reference 16, whose source and drain are respectively connected at the terminals B1 and B2 of the generator 3, and the grid of which is connected to the direct output Q of the flip-flop 13.
  • transistor 16 is blocked or conductive depending on whether its gate is in the "0" or "1" logic state since it is of type n and its source is at the reference potential.
  • the servo circuit 7 also includes an initialization circuit 17 having two connected inputs respectively at the terminals 5c and 5d of the rectifier 5 and an output connected on the one hand to the reset inputs R of the frequency divider 10 and the reversible counter 11 and, on the other hand, to the second input of the OR gate 14 .
  • This initialization circuit 17 will not be described in detail since it can be produced in various well known ways. It will simply be mentioned that it is arranged so that its output produces a short initialization pulse at the moment when the voltage Ua reaches by increasing a determined threshold value, which is equal to or slightly greater than the value for which the various other components of the servo circuit 7 begin to function properly. This instant will be called initialization instant t0 in the rest of this description.
  • the pulse produced by the initialization circuit 17 causes the frequency divider 10 and the reversible counter 11 to be reset to zero, so that the outputs Q1 and Q2 of the frequency divider 10 and the output Q of the reversible counter 11 are put in the logic state "0".
  • the logic state "0" of the output Q of the flip-flop 13 puts the transistor 16 in its blocking state, so that the coil 3b of the generator 3 is not short-circuited and that the speed of rotation of the rotor 3a can reach and exceed the set speed Vc.
  • the logic state "1" of the output Q ⁇ of flip-flop 13 maintains the content of counter 15 at zero.
  • reference instant tr will be called each of the instants when the reference signal SR goes from its state “0" to its state “1” and where the content of the counter 11 is therefore increased by one.
  • the instant of measurement tm will be called each of the instants where the measurement signal SM also passes from its state “0" to its state “1” and where the content of the counter 11 is therefore reduced by one unit.
  • the angular position of the rotor 3a will be called the angular position that it should occupy, at each reference instant tr, if its average speed of rotation since the instant t0 had been equal to its reference speed Vc.
  • the content of the reversible counter 11 is permanently representative of the difference between the number of pulses of the signal SR produced by the frequency divider 10 since the time t0 defined above and the number of pulses of the signal SM produced by the comparator 8, which is the number of complete turns made by the rotor 3a of the generator 3, from the same instant t0.
  • This content of the counter 11 is therefore also permanently representative of the delay or of the advance of the rotor 3a with respect to its theoretical angular position, this delay or this advance possibly being, if necessary, several turns.
  • the output Q of the reversible counter 11 is in the logic state "0", so that the output of the AND gate 12 remains in the state "0" and that the flip-flop 13 remains in the state where its output Q is in logic state "0".
  • the transistor 16 remains blocked, and the coil 3b of the generator 3 not being short-circuited, the speed of rotation of the rotor 3a can remain or, if necessary, tend to become greater than the reference speed Vc, provided that understood that the barrel spring 2 is still sufficiently armed.
  • the output Q of the counter 11 is in the logic state "1".
  • the signal SM then also being in state "1", the flip-flop 13 takes the state where its outputs Q and Q ⁇ are in logical state "1" and in logical state "0" respectively.
  • the transistor 16 becomes conductive and short-circuits the coil 3b of the generator 3.
  • the rotor 3a is therefore braked, and its speed of rotation becomes lower than the reference speed Vc.
  • the flip-flop 13 then resumes the state where its outputs Q and Q ⁇ are in logical state "0" and in logical state "1" respectively.
  • the transistor 16 is therefore again blocked, so that the rotor 3a is no longer braked and its speed of rotation can again increase.
  • the circuit formed by the doors 12 and 14, the rocker 13 and the counter 15 constitutes a circuit for limiting the duration of braking of the rotor 3a to a determined fraction, 1/8 in the present example, of the period of the voltage Ug supplied by the generator 3.
  • the average speed of the rotor 3a is equal to the set speed Vc, and, if the hands 6 have been set to the time at time t0, they permanently display the exact time, with an accuracy equal to that of the frequency of the reference signal SR.
  • this result is obtained by braking the rotor 3a, when it is ahead of its theoretical angular position, only for periods of limited duration, significantly less than the time taken on average by the rotor 3a to do a full turn.
  • this duration of the braking periods which is determined by the frequency of the signal SC and by the number of flip-flops forming the counter 15, is approximately eight times shorter than the average rotation period of the rotor 3a.
  • the voltage Ug produced by the generator 3 is obviously zero since the transistor 16 is conductive and short-circuits the coil 3b.

  • the elimination of this resistance has the advantage that the braking of the rotor 3a is more effective, which makes it possible to increase the maximum admissible engine torque for the barrel spring 2 and therefore to increase the autonomy of the timepiece 1.
  • the rotor of the generator of a timepiece may comprise, instead of the bipolar magnet of the rotor 3a of the generator 3 described above, either a permanent multipolar magnet, or a plurality of bipolar permanent magnets arranged at the periphery of a disc.
