- Electromechanical exhaust device and timepiece using such a device Electromechanical exhaust device and timepiece using such a device.
- the present invention relates to an electromechanical exhaust device and a timepiece using such a device.
- the exhaust device serves on the one hand to maintain the oscillatory movement of the mechanical oscillator comprising the balance and the hairspring and on the other hand to transmit the frequency of this oscillator to the gear train causing the time display.
- the traditional mechanical exhaust devices transmit the frequency of the mechanical oscillator directly to the gear train causing the time display.
- the frequency of the mechanical oscillator generally between 2 and 4 Hz, is unfortunately not very precise and in addition very dependent on the position of the watch. The accuracy of a mechanical watch is therefore lower than that of an electronic quartz watch.
- An object of the present invention is to provide an electromechanical exhaust device for significantly improving the accuracy of a mechanical watch.
- Another object of the invention is to propose a mechanoelectronic timepiece equipped with such an exhaust device.

- FIG. 1 represents a block diagram of a traditional mechanical watch in which the mechanical energy coming from a manual or automatic winding device is stored in a mainspring 1 to be distributed through a set of wheels 2 to a exhaust device 3 and a display 4.
- the exhaust device 3 serves on the one hand to maintain the movement of the mechanical oscillator 5 comprising a balance and a hairspring and on the other hand to transmit the frequency of this oscillator to the gear 2 causing the time display 4.
- the frequency of a mechanical oscillator generally between 2 and 4 Hz, is unfortunately not very precise and, moreover, very dependent on the position of the watch. The accuracy of a traditional mechanical watch is therefore lower than that of an electronic quartz watch.
- FIG. 2 represents a schematic diagram of a mechanoelectronic watch using an electromechanical exhaust device according to the invention.
- the stored mechanical energy "in a barrel spring 6 is dispensed through a set of wheels 7 to an electromechanical escapement device 9 and a display 8.
- the electromechanical escapement device 9 according to the invention has multiple functions :
- the first is to maintain the oscillation movement of the mechanical oscillator 11
- the second is to transmit the frequency of the oscillator 11 to the wheel 7 causing the time display 8
- the third is to transform a portion of the mechanical energy received into electrical energy to power the electronic device 10 which has a quartz time base
- the last function of the electromechanical exhaust device 9 is to advance the train 7 when it receives electric correction pulses from the electronic device 10.
- the gear 7 linked to the display 3 and the electromechanical exhaust device 9 advance by a fixed angle and transmit, through an electromechanical converter described below. of the device 9, the electrical energy and the oscillation period of the mechanical oscillator 11 to the electronic device 10.
- This electronic device 10 has an electric energy accumulator and a quartz time base taken as reference time base ; he compares the periods of mechanical oscillation with a reference period. When the sum of the differences between these periods exceeds a certain limit, the electronic device 10 sends electrical correction pulses through an electromechanical converter to advance the electromechanical exhaust device 9 as well as the gear 7 and the display 8.
- the electromechanical escapement 9 advances at each period of the mechanical oscillator 11 and also, so independent of the mechanical oscillator 11, when it receives pulses coming from the electronic circuit 10.
- the timepiece To obtain a good operation of the timepiece according to FIG. 2, it is sufficient to adjust the period of the mechanical oscillator 11 slightly greater than that of the reference time base of the quartz timebase.
- the electronic circuit 10 measures the difference between these periods and sends a set of correction pulses to catch up. In practice setting the period of a mechanical oscillator with an accuracy of one per thousand is easily achievable.
- FIG. 3 represents an embodiment of an electromechanical exhaust device according to the invention. This device comprises several mobiles rotating around 4 centers 01, 02, 03 and 04.
- the escape wheel 12 shown in detail in FIG. 4, rotates about the center 01 and is provided with pins 121.
- the number of pins is equal to 8, but the choice of another number of pins is also possible.
- FIG. 7 shows the details of these mobiles as well as the electromechanical converter 18 having, in addition to the rotor 182, a stator 181 of soft magnetic material provided with the cells 184, and a coil 183.
- the electromechanical converter 18 has several distinct functions:
- the rotor 182 has two stable equilibrium positions aligned on the axis S1-S2 in the absence of current in the coil 183,
- Figure 9 illustrates the mechanical release phase.
- the pin 152 of the plate 15 rotating in the direction of the arrow F3, actuates the release means 16 and, through the wheels 17 and 13, releases the pin 121 of the locking means 14.
- the wheel exhaust 12 can
- Figure 10 illustrates this phase of energy transmission. After the mechanical release phase, the escape wheel 12 rotates in the direction of the arrow F2, one of the pins 121 of this wheel operating the pulse lever 151 of the plate 15 to provide the energy
- Electromagnetic release phase this phase is illustrated in FIG. 12.
- One of the peculiarities of the electromechanical exhaust device according to the invention is that it is able to release the escape wheel 12 from the locking position, so as to independent of the frequency of the mechanical oscillator 11.
- To do this simply send a set of electrical pulses to the coil 183 of the electromechanical converter 18.
- the interaction between the magnetic field created by the current in the coil 183 and the magnetic field of the rotor magnet 182 generates an electromagnetic torque in the direction of the arrow F5, greater than the positioning torque, which actuates the locking means 14 in the opposite direction through the wheels 13 and 17.
- the electromagnetic release phase is generally performed outside the phases of mechanical release, energy transmission and repositioning. During this phase, the angular velocity of the mechanical oscillator 11 is practically zero. In this phase of electromagnetic release, the escape wheel 12 transmits no energy to the mechanical oscillator 11.
- FIG. 13 represents the block diagram of the electronic device 10 of FIG. 2. This device comprises:
- the electrical signal from the coil 183 during the energy transmission phase is sent to the charging means 100, which stores the energy in a capacitor or other energy accumulator 101. This signal is also sent to the setting means. 102, which transmit the information to the means 103 for measuring the period of the mechanical oscillator 11, based on a reference time base from a crystal oscillator 104.
- the means 105 calculate the sum of the errors of the mechanical period and send a set of electrical pulse correction coil 183 when this sum exceeds a certain limit.
- a timepiece equipped with an electromechanical exhaust device as described above has its operating accuracy significantly improved since it depends on the accuracy of the quartz oscillator.
