Definitions

  • the present invention relates generally to a timepiece with micro-generator with power reserve indicator.
  • the invention relates more particularly to the means for providing this power reserve indication. It also describes the method used to indicate the power reserve.
  • a timepiece represented in FIG. 1, comprising a source of mechanical energy formed by a cylinder 1 in which is housed a spring 1a, manual or automatic winding, the winding device is not shown here.
  • the barrel 1 is mechanically coupled to the magnetized rotor 2a of an electric generator 2 via gear 3.
  • the generator 2 comprises at least one coil 2b from which is generated an alternating voltage Ug, when the magnetized rotor 2a is driven by rotation, generating a magnetic field symbolized by means of an arrow and with which is coupled said at least one coil 2b.
  • the terminals of the coil 2b (or coils) are connected to a rectifier 4 outputting a rectified voltage Ua for supplying the regulator circuit 6, which will be discussed below.
  • the rotation speed of the needles 5 is maintained at a constant mean value by means of the regulator circuit 6, which is intended to slave the frequency of the generator to a reference frequency, so that the speed of the hands corresponds to the speed required to obtain a correct indication of the time.
  • This regulator circuit 6 comprises a clock-stabilized oscillator 6a of a watchmaker-type quartz and a frequency divider 6b reducing the frequency of this oscillator 6a to a frequency usable by a logic circuit which controls 6c, by means of a control signal, a switching member 7, for example a transistor, for braking the generator 2 in order to regulate its frequency at a reference frequency advantageously corresponding to a correct indication of the time by the display members of the indication time 5.
  • the timepiece according to this document also comprises a device indicating the power reserve 9.
  • This device comprises a counter 9a counting the successive braking signals 8 for a period of time determined by means of an additional frequency divider 9b .
  • a memory 9c is connected at the output of the counter 9b so as to store the data counted during the determined period of time, at the output of which is connected a decoder 9d transforming the stored data into a control signal of the display means 9e.
  • the power reserve comprising successive lines which illuminate or appear to the point corresponding to the value of the measured or calculated quantity, produced by means of either a colored strip or a liquid crystal cell.
  • a timepiece with a generator whose autonomy is higher.
  • Such a timepiece represented in FIG. 2, furthermore comprises common elements, bearing the same numerical references and already described with reference to FIG. 1, a storage device 10 intended to store and to restore energy. electric constituted by a part
  • This storage device 10 connected to the terminals of the rectifier 4 comprises a conventional accumulator 10a.
  • the voltage Ug is obviously zero. If, in addition, the accumulator 10a of the storage device 10 is discharged, the voltage Ua is also zero, or in any case insufficient for the timepiece to operate. If the barrel spring 1 a is then raised, there comes a time when the rotor 2a begins to rotate, and where the Ug and Ua voltages start to increase.
  • the accumulator 10a is completely, or at least almost completely, discharged when the timepiece is stopped.
  • the accumulator 10a begins to charge by absorbing a portion of the electrical energy supplied by the generator 2. This additional electrical energy is of course provided by the barrel spring 1a and comes from the conversion by the generator 2 of at least a portion of the mechanical energy of the spring.
  • the electrical energy produced by the generator 2 becomes insufficient to supply the various components of the regulator circuit 6 correctly.
  • the accumulator 10a is then at least partially charged, so that the storage device 10 maintains the voltage Ua at a value such that the components of the regulator circuit 6 operate correctly.
  • the electrical energy necessary for this operation is then provided, at least partially, by the accumulator 10a.
  • this timepiece which comprises a storage device 10 capable of storing, in the form of electrical energy, a part of the mechanical energy contained in its mainspring, is increased by means of means which make it possible to use this electrical energy to operate the timepiece after the mainspring is no longer sufficiently armed.
  • the idea according to the invention is to provide a reliable indication of the power reserve at the request of the user, without disturbing the normal operation of the timepiece, ie all ensuring a correct indication of the time.
  • the electromagnetic braking device of the generator allows, with full power reserve, that is to say with the spring of the fully armed barrel, to release a power relatively large average.
  • the idea is therefore to modify the braking device so as to recover and store electrically the energy dissipated during the braking periods, within a reasonable period of time so as to be able to momentarily display additional information, such as, for example, the reserve of walk.
  • electrical energy storage means are provided for storing the energy dissipated during the braking periods of the generator as well as actuating means for activating, on request, means for indicating the power supply.
  • power reserve of the timepiece thanks to the electrical energy stored previously.
  • the subject of the present invention is a timepiece with a generator whose characteristics are set forth in independent claims 1 and 10.
  • the invention proceeds, as already mentioned, from the general idea of accumulating the electrical energy dissipated during braking periods of the generator in order to have enough energy to indicate, on request, the power reserve. of a timepiece.
  • the energy dissipated during the braking periods of the generator represents an average instantaneous power of approximately one microwatt (ie a mean current microamper under about one volt ), insufficient to continuously supply a power reserve indicator.
  • the idea is to be able to accumulate, within a reasonable period of time, for example a few minutes, sufficient energy to momentarily display the power reserve. An amount of energy between 40 and 80 microjoules is amply sufficient. This energy must also be released in a short time, ie we must have a much higher instantaneous power (up to a thousand times more) than the average braking power dissipated, depending on the type of indicator. the power reserve used.
  • FIG. 3 shows a simplified diagram of a timepiece according to a preferred embodiment of the invention.
  • FIGS. 1 and 2 There are a number of elements common with those presented in the context of the prior art in FIGS. 1 and 2, elements which will not be repeated in detail here and whose numerical references remain unchanged.

  • the barrel is mechanically coupled, on the one hand, to the generator 2 whose output voltage Ug generated at the output is rectified through an active rectifier 4 and, on the other hand, to display means of a time indication 5, typically needles, through the workings 3 of the watch movement.
  • the rotation speed of the needles is maintained at a constant average value by means of the control circuit 6, or regulator circuit, designed to slave the frequency of the generator 2 to a reference frequency, so that the speed of the hands corresponds to the speed required to obtain a correct indication of the time.
  • the timepiece further comprises electric energy storage means 11 arranged so as to accumulate the electrical energy dissipated during the braking periods of the generator 2, ie during short circuits applied to the generator by the switching means 7.
  • the switching means 7 are activated by the regulator circuit 6 when the frequency of the generator is greater than the reference frequency, ie when the rotational speed of the rotor 2a is greater than the speed needles corresponding to a correct indication of the time.
  • the switching means 7 can occupy two positions, a first position 7a, in which the generator 2 is connected to the accumulation means 11 ensuring optimum impedance matching with the generator so as to draw maximum power instantly from the latter, which has the effect of braking and a second position 7b, in which the generator 2 is connected to the regulator circuit 6 for controlling the frequency of the generator with respect to a reference frequency corresponding to a correct indication of the 'hour.
  • the accumulation means 11 are preferably formed by a voltage booster 11a and a storage element 11b.

Note of course that other types of charge pump can be used.

  • the accumulation element 11b preferably a storage capacitor having a capacity of about 10 microfarads at 3 or 4 volts, can accumulate after a few minutes of braking, an energy of the order of 40 to 80 microjoules.
  • the timepiece comprises an indicator, not shown here, arranged on the dial to indicate when the accumulation element 11b is sufficiently charged to power a power reserve indication device 12
  • This device for indicating the power reserve 12 comprises means for displaying the power reserve 12a and a control system 12b for these display means.
  • the control system 12b has been shown here independently of the control circuit 6, but it will be noted that it could be integrated in the control circuit 6 as well.
  • the control system of the display of the power reserve is actuated (signal P) by actuating means 13 of the timepiece accessible externally, such as for example a push button called "request".
  • the purpose of this control system is to provide an accurate indication of the power reserve (signal R) on the basis of a measurement (signal C) of the power reserve transmitted by the control circuit 6.
