Definitions

  • the present invention relates to a watch with a generator module for converting kinetic energy into electrical energy useful for the operation of the watch.
  • Substitution of the battery includes, for the producer, the need to provide openings, often sealed, in the bottom of the watch, for example, to perform the substitution. These openings and additional parts involve additional costs for the watch.
  • the present invention therefore proposes to solve these difficulties and to propose a watch powered by a generator which is free from the disadvantages mentioned above.
  • Another object of the invention is to provide a watch in which the state of charge can be easily checked.
  • Another object of the invention is to provide a watch of simpler design and construction.
  • the "face" side of the watch indicates the upper side, the one where the time indicators are.
  • FIG. 1 shows a watch 10 according to the invention comprising, in a box 20, a quartz digital watch movement, with a digital display device visible through the ice 40.
  • the box 20 is, for example, metal and arched to fit the curve of the wrist of the wearer, as shown in the figures. It is understood, however, that the invention is not limited to these features, and one could also consider a box arched or flat bottom, ceramic, plastic, composite, or any other suitable material.
  • the display device or dial preferably comprises two lines of alphanumeric characters and / or other graphic symbols.
  • one line for example the upper line, is intended for displaying the time, while the other line of display is used for displaying another function of the watch, for example a function chronograph, alarm clock, time zone, calendar, thermometer, altimeter, barometer, short messages, calculator, phone, calendar or any other function.
  • the present invention also includes variants with different display devices, for example analog needle displays, or mixed analog-digital displays.
  • the watch comprises input and control devices, for example the push button 24 on the caseband, to allow the user to control the operation of the watch, activate the various functions and perform the time setting, from conventional way.
  • input and control devices for example the push button 24 on the caseband
  • the watch also comprises, on the middle and partially occupying the face, an easySkroll® type control roller 22, which can be actuated in rotation and pressure by the tip of a finger.
  • an easySkroll® type control roller 22 which can be actuated in rotation and pressure by the tip of a finger.
  • buttons on the face are also possible and included within the scope of the present invention.
  • non-exhaustive input devices include buttons on the face, conventional type crowns, magnetic contacts or touch-sensitive glass.
  • the ice 30 allows the vision of an oscillating mass, free to rotate about a fixed axis of rotation, driving an electric generator, not visible in Figure 1, which provides the power of the movement, as will be seen by the after.
  • the ice 30 is separated from the ice 40 of the display. This arrangement makes it possible to hide the electrical elements between the generator and the display under portions of middle section.
  • the generator which is, according to a variant of the invention, below the latter, can also be partially or completely visible.
  • the watch comprises an oscillating mass 50, free to rotate following the movements of the wearer, around its central axis.
  • the mass 50 causes, by a transmission not shown, the generator 55.
  • the generator module comprises a spring, tensioned by the movement of the oscillating mass, and an automatic clutch device for actuating the generator when the spring tension exceeds a predetermined threshold. Once the spring is relaxed, the generator stops and this cycle, which can be repeated several times per minute if the carrier is very active, starts again.
  • This variant is advantageous because it makes it possible to rotate the generator very quickly, thus reducing part of the energy losses that take place if it turns too slowly.
  • the generator 55 can be driven directly by the oscillating mass 50, with a synchronous transmission with a timely gear ratio always in engagement.
  • Generator 55 is for example a micro-alternator with permanent-magnet rotor, or any other known electric generator.
  • the electrical output of the generator 55 is directed to the electrical storage module 60 which comprises, in a variant, a rechargeable battery and an electronic charger circuit, which transforms, by for example, the alternating current from the generator, in direct current suitable for charging the accumulator.
  • the accumulator will for example be a Li-ion, Li-Poly or NiMH battery, a supercapacitor or any other accumulator, depending on the circumstances.
  • the movement 80 is a quartz movement with digital display, for example, powered by the energy stored in the storage module 60.
  • the watch has a ring that allows to manually rotate the generator, by a suitable transmission, and thus store in the module 60 sufficient load for the start of the watch, for example.
  • the generator module comprising the oscillating mass 50, the generator 55 and the transmission, the storage module 60 and the movement 80, are mechanically independent of each other, and require only a few electrical interconnections to ensure the operation of the watch.
  • the display module 88 and the oscillating mass 50 are arranged side by side and substantially at the same level. This arrangement makes it possible to reduce the thickness of the watch and to obtain an aesthetically interesting result.
  • the movement 80 and the generator module, comprising the oscillating mass 50 and the generator 55 are mounted in the box 20 independently and separately.
  • the oscillating mass 50 and the generator 55 are superimposed, parallel to each other, but not parallel to the plane of movement 80 and its plate.
  • the storage module 60 is neither parallel to the movement stage nor to the generator. This advantageous arrangement makes it possible to arrange the three elements juxtaposed according to an arc of a circle matching the shape of the wrist.
  • a storage module a storage element occupying the housing provided for this purpose for the battery in the movement of the watch.
  • the construction and the design of the watch result simpler than in the case of a traditional construction on platinum.
  • the elements of the watch can be placed with the greatest freedom and a rational and economical construction can be obtained which exploits the available volume optimally.
  • the generator module with its oscillating weight can be placed next to an existing movement in the watch case.
  • the movement can be constituted by an existing quartz electronic movement, available at low cost, and able to operate without the generator module with, if necessary, an adaptation of the software.
  • the only material modifications to be made to this existing movement to extend its power reserve are to connect it electrically to the generator module, and possibly to replace the battery with a rechargeable battery.
  • the movement 80 comprises a control unit 82, for example a microprocessor or a dedicated logic circuit ASIC, or an FPGA or equivalent programmable logic integrated circuit, whose operating rate is rigorously fixed by an oscillator. quartz 84.
  • the control unit is supplied with energy by the storage module 60 and receives commands from the input devices 22 and 24 of the watch, to activate, for example, the various functions of the watch and control the display 88 appropriately.
  • the control device comprises an energy monitoring module 86, which controls the state of charge of the battery of the storage module 60, as well as the powers delivered by the generator 55 and consumed by the movement 80.
  • monitoring may be, for example, a dedicated electronic circuit, or a software module included in the firmware of the controller 82. It can also be partially or totally included in the storage module 60.
  • the state of charge of the battery can be obtained from its voltage and temperature, in a known manner, or by temporal integration of the charging and discharging currents, and the spontaneous discharge of the battery.
  • the state of charge of the battery will be obtained by an intelligent battery management system (Smart Battery System), which optimally integrates the electrical, thermal and historical data available to achieve a reliable determination of the state of the battery. charge.
  • Smart Battery System Smart Battery System
  • the energy monitoring module ensures optimal management of the consumption of the watch, and can, if the charge of the battery falls below a predetermined level, for example, activate one or more low-power modes, for example by inactivating non-essential functions of the watch that consume significant power. Examples of non-essential functions but of high consumption include the lighting of the display, and the ringing.
  • a low power mode can reduce the power consumed by these functions, but not disable them completely. For example, you could reduce the intensity of the lighting and limit the volume and duration of the ring.
  • a low-power mode could also include disabling all interactive features and display.
  • the watch would be limited, in the low power mode, to keep the time internally until the storage module 60 reaches a satisfactory level of charge.
  • a low mode consumption may comprise the total inactivation of the movement 80 and / or the display of a discharge indication.
  • one or more low consumption modes can be activated on the initiative of the wearer, for example by acting on one of the input devices 22, 24.
  • the activation of a low power mode can derive from an evaluation of other parameters than the state of charge of the battery.
  • a low power mode may be activated, for example, when the average generated power is low or zero during a long time interval, indicating that the watch is not worn.
  • the watch provides an energy balance display mode, in which the information concerning the state of charge and / or the power generated and consumed, available by the monitoring module 86, are presented. on the display 88.
  • the state of charge of the battery is converted into hours of operating autonomy, based on an average consumption forecast, for example.
  • the instantaneous power reserve of the watch ie the autonomy of the watch in the absence of recharging by the generator 55.
  • the load battery simply as a percentage of a maximum charge.
  • the display of the generated and consumed powers also allows the user to appreciate the autonomy of the watch. Preferably we will not display the instantaneous powers, very variable, but an average power calculated on an adequate time base, for example a few hours.
