Definitions

  • the present invention relates to a device power reserve indication for a part electronic watchmaking.
  • the invention relates to such a device for an electronic timepiece in which electrical energy is generated by a generator powered by a spring barrel.
  • Such a device for indicating the reserve of step could be used in a timepiece of the electronic type comprising an energy generator electric coupled to the spring barrel and intended for supply a timepiece electronic circuit regulated by a quartz oscillator.
  • the object of the invention is to propose a solution simple and effective in this context to indicate so flawless and clearly the power reserve of an electronic timepiece that draws its energy electric of a generator driven by a spring of barrel, this generator also serving to regulate the walk from the room.
  • the invention therefore relates to a timepiece comprising a barrel, a spring housed in this barrel, mechanically coupled time display devices audit barrel, a generator of electrical energy also mechanically coupled to said barrel and intended to deliver an AC voltage, a connected rectifier to said generator to deliver a DC voltage to from said AC voltage, and a circuit regulator powered by said DC voltage and intended to control the speed of rotation of said generator to a set speed, said regulator circuit for this purpose comprising means for braking said generator when said regulator circuit finds that said generator rotates at a speed greater than said set speed.
  • This timepiece is characterized in that said means for braking said generator are arranged so as to exert on this generating successive braking and in that it includes a power reserve indicator device arranged to perform a measurement relating to said successive braking and to provide an indication visual of the power reserve as a function of this measured.
  • Figure 1 represents a simplified general diagram of a part of watchmaking according to the invention. It should be noted that the part of this diagram concerning the regulator circuit intended to control the speed of rotation of the generator of this timepiece, will not described in detail here, the skilled person can without hardly build this slaving device while referring to the description of the Swiss patent application No 686 332 in the name of the Applicant patent application. However, to make it easier understanding of the present invention, it will be recalled briefly here the essential elements of the diagram and operation of this regulator circuit.
  • the timepiece equipped with a device for indicating the power reserve according to the invention has a mechanical energy source formed by a barrel 1 housing a spring 1a of the usual type in the horological technique, with manual or automatic winding.
  • Barrel 1 is mechanically coupled to rotor 2a an electric generator 2 via a gear train 3 symbolized by mixed lines.
  • Generator 2 includes a coil 2b at terminals B1 and B2 from which an alternating voltage is generated Ug, when the rotor 2a is rotated, this rotor bearing a permanent magnet generating a field magnetic symbolized by an arrow in Figure 1 and with which the coil 2b is coupled.
  • the terminals B1 and B2 of the coil 2b are connected to a rectifier 4 whose output terminals 4a and 4b provide a continuous voltage Ua derived from the voltage Ug alternative and intended to supply the various circuits of the timepiece.
  • Needles 5 or any other conventional means mechanical time display are coupled to the train gear 3 to allow time display current and possibly date and day and other time indications.
  • the rotation speed of the hands 5 is maintained at a constant average value thanks to a circuit regulator 6 which controls this value at a speed of setpoint Vc.
  • the regulator circuit components 6 are designed to adjust the speed of rotation of the rotor 2a, so that the 5 hands rotate at the required indication speed just an hour, when the rotor turns at the speed of setpoint Vc. This is four turns per second, per example.
  • the servo circuit 6 includes an oscillator 7 stabilized by a watchmaking type quartz and a divider of frequency 8 reducing the frequency of this oscillator to a value usable by a functional block 9 which controls the grid of a semiconductor component 10, by example an n type MOS transistor.
  • This semiconductor component when it is made conductive, allows to short-circuit this coil and thus have a braking effect on the movement of generator rotation 2.
  • the brake control signal SF which circulates on a line 11 between the functional block 9 and the grid of the semiconductor component 10 is of logic type and in the example shown, we admit that this signal is in the state logic "0" as long as the timepiece delays, that is to say as long as the average speed of the rotor 2a is lower than the set speed Vc. In these conditions, the component or transistor 10 remains blocked and the rotor 2a is not braked.
  • the brake control signal SF is made up of pulses of determined duration starting at the start of each alternation, for example positive, of the Ug voltage at terminals B1 and B2 of coil 2b. during each of these pulses of the control signal SF, this one is in state "1" making the transistor 10 conductive and braking the rotor 2a.
  • the invention is based on the observation that the braking signal SF circulating on the conductor 11, in other words the frequency with which the rotor 2a is braked, is a measure of the arming state of the spring 1. Indeed, when the barrel spring is completely raised, i.e. the reserve of is maximum, the engine torque it produces is maximum. In these conditions, the rotor will have permanently tendency to spin faster than speed Vc setpoint and must therefore be braked at each start of a period of Ug tension.
  • the device for indicating the power reserve thus includes means which account for successive braking over periods successive times of predetermined duration and which develop a display signal from the number of brakes occurring during these periods of time successive.
  • connection 11 of the functional block 9 which transmits the brake control signal SF at transistor 10 is connected to a counter 13 responsible for counting the number of this signal. Its counting input C is therefore connected to connection 11. Its reset input R is connected to the output Q of a frequency divider 14 which fixes successive time periods of duration predetermined. In this case, the entry of this divider 14 is connected to the output of the frequency divider 8 of to further divide the output frequency of the last.
  • the clock input C of this memory is connected to the output Q of the divider of frequency 14.
  • the outputs Q1 to Q4 of memory 15 are respectively connected to the inputs E1 to E4 of a decoder 16 whose outputs, here S1 to S9, are connected respectively in turn at inputs E1 to E9 of the means display or display 17.
  • the output signal of the frequency divider 8 at a period of 250 ms.
  • the divisor division rate of frequency 14 is 2048, which gives rise to its one pulse output every 512 seconds (see figure 2). This signal thus determines the period of time predetermined during which we count the times that the transistor 10 puts the coil 2b in short circuit.
  • the rotor 2a rotates too fast by relative to the set speed Vc during the duration whole of the counting period and is braked at the start of each period of Ug tension (this means that the spring is only at the beginning of its relaxation), the number of pulses of the control signal SF is greater than 2048. Therefore, the counter 13 must have a capacity upper and have one more toggle which gives a minimum necessary capacity of 4096.
  • Figure 2 illustrates with a diagram representing some significant signals as a function of time, how does the device for indicating the power reserve that we have just described.
  • Curve a shows the divider output signal of frequency 14. This signal has a duration period D, chosen here as being equal to 512 seconds.
  • Curve b shows the SF signal applied to the input of counting the counter 13, it being understood that the figure shows, by way of illustration, two counting periods relatively spaced during which the numbers of pulses are quite different from each other. They therefore account for two operating phases during which the winding of the spring is strong, respectively weak.
  • Curve c) represents the content of counter 13 respectively during the two periods represented, while curve d) shows the output of memory 15 which each time keeps the information of the period of previous count and which is reset to zero each counting period expires thanks to a signal reset which passes over a conductor 18 (figure 1).
  • Figure 3 shows some examples of implementation practical display means 17.
  • the figure represents in a), b), c) and d) displays indicating the value memory output 15 respectively by an indication not graduated (a)) or graduated in 12 hour intervals for example (b), c), and d)).
  • dial C of the coin watchmaking may include a G window behind which moves a colored strip which is animated by a small actuator (not shown) receiving its signal decoder 16 control.
  • a series of light-emitting diodes may be used to design them easily.
  • the resolution of the display 17 can be arbitrary, for example by periods of a determined number of hours, as shown in b), c), d) and f) of Figure 3, by units of hours as in e), or by all or nothing using a single indicator, a variant which has not been shown in the drawings.
  • the skilled person will know adapt memory 15, decoder 16 and display 17 to these different display possibilities that fit all within the framework of the invention.
  • memory 15 cannot memorizes that a certain number of most significant bits of the output information of the counter 13, for example the four most significant bits, as shown in the figure 1. Under these conditions, we can theoretically display 16 separate information on display 17. This is generally considered redundant for the envisaged goal, a maximum of nine pieces of information should be sufficient to provide adequate information the user of the timepiece on his reserve of market.
  • the device according to the invention can, to some extent, inform the user on the mechanical state of the part of watchmaking. For example, if display 17 fails not at the maximum reserve graduation, whereas the user has just completely wound the spring, this will mean for example that the timepiece has need overhaul and requires re-lubrication.
