Definitions

  • the invention relates to an electronic watch comprising a Dewar device, such a watch being particularly suitable for operating under extreme temperatures.
  • a Dewar device such a watch being particularly suitable for operating under extreme temperatures.
  • Such an electronic watch is for example a quartz watch.
  • An electronic watch conventionally comprises a bracelet and a watch case comprising several electrical or electronic components. It is known in the state of the art that some of these components cannot withstand extreme temperatures, and cease to function correctly at these temperatures.
  • liquid crystal displays LCD standing for Liquid Crystal Display
  • quartz tolerate temperatures not exceeding 80 ° C (degrees Celcius) approximately, and not dropping below 0 ° C.
  • the temperatures can frequently reach values of the order of appreciably -150 ° C to +125 ° C.
  • the invention relates to an electronic watch comprising a bracelet and a watch case comprising at least one electrical or electronic component, said watch comprising at least one Dewar device configured to contain at least one of said electrical or electronic components.
  • the Watch case of at least one Dewar device which encapsulates the electrical or electronic components of the watch, the latter are protected from any extreme temperatures outside which may be between -150 and +125. degrees Celsius.
  • Such a watch configuration thus makes it possible to use standard electrical or electronic components in contexts and environments where temperatures can be extreme, such as, for example, space or lunar missions. This thus makes it possible to rationalize costs as well as to maintain a reasonable complexity for the components used in the watch for such missions.
  • the figures 1 to 3 represent an electronic watch 2 according to the invention.
  • the electronic watch 2 comprises a bracelet 4 and a watch case 6.
  • the electronic watch 2 is for example a quartz watch.
  • the watch case 6 conventionally comprises at least one electrical or electronic component 8a-8g.
  • the watch case 6 comprises seven electrical or electronic components 8a-8g, which constitute sensitive parts of the watch 2.
  • the watch case 6 may include more electrical or electronic components than those shown in these figures, or can only have a subset of components among components 8a-8g.
  • the watch case 6 thus comprises for example a display device 8a, a processor 8b, a memory 8c, an energy storage component 8d, a motor 8e, an integrated circuit 8f and an electronic oscillator 8g .
  • the watch case 6 further comprises a Dewar device 10.
  • This Dewar device 10 has the same properties and characteristics as a Dewar tube / vessel well known in the state of the art. As will be seen below, the properties and characteristics of this Dewar device 10 contribute to giving it good thermal insulation from the look. temperatures that may prevail in the external environment in which it may be located.
  • This device comprises a confinement / encapsulation space which is here a volume defined inside this device 10 and which is designed to receive at least one of said electrical or electronic components 8a-8g so that it is thermally insulated. the external environment.
  • the watch case 6 therefore comprises this Dewar device 10. More precisely, this Dewar device 10 is formed in whole or in part by the watch case 6. Such a Dewar device 10 is pre-configured to contain at least one of said electrical or electronic components 8a-8g. In other words, this device 10 comprises the space 14 in which each component can be arranged by being encapsulated in this space 14.
  • the Dewar device 10 can contain all the electrical or electronic components 8a-8g of the watch 2.
  • this Dewar device 10 is then formed by parts of the watch case 6 such as a middle part 20, a mirror 18 and a bottom 19. The assembly of these parts helps to create the confinement space 14 of this Dewar device 10 provided for the arrangement of the components 8a-8g.
  • These three parts, the middle 20, the crystal 18 and the back 19 can be separate pieces and subsequently joined together to construct this encapsulation space 14.
  • the middle 20 and the back 19 of the case can form together a single piece visible on the figure 2 , said one-piece part defining an opening opposite the bottom 19 which is capable of being closed by the glass 18 and this, in a removable manner.
  • the middle part 20 and the crystal 18 of the watch case 6 can together form a single piece, said one piece piece defining an opening opposite the crystal 18 which is capable of being closed by the bottom 19 and also removably. In these configurations, the space 14 is formed between these three parts.
  • the watch case 6 comprises an enclosure 21 conventionally comprising the movement of the watch and which is delimited in particular by the internal walls of the middle part 20 and of the back 19.
  • Such an enclosure 21 also comprises at least one Dewar device 10 containing the at least one of said electrical or electronic components 8a-8g.
  • This Dewar device 10 can contain / encapsulate a single component or several components at a time.
  • This Dewar 10 device can be integrated into the movement of the watch 2.
  • the Dewar device 10 typically comprises two thin walls 12a, 12b nested one inside the other.
  • a wall internal 12a of device 10 delimits the confinement / encapsulation space 14 inside which each electrical or electronic component 8a-8g is arranged.
  • An outer wall 12b of the device 10 is arranged on the outer side of the watch 2.
  • the Dewar device 10 thus defines an empty or almost empty space 16 which separates the first inner wall 12a from the second outer wall 12b.
  • These walls 12a, 12b are preferably made in a nonlimiting and nonexhaustive manner in a metallic material, in glass or in thermosetting or thermoplastic polymer resins reinforced with carbon or glass fibers or else in ceramic materials.
  • the internal and external walls 12a, 12b are transparent or semi-transparent, being for example made of glass, the external surface of this internal wall 12a and the internal surface of this external wall 12b are coated with a reflective metallic coating. or the like, such as for example a silver layer.
  • the crystal 18 of the watch case 6 is formed by a transparent or semi-transparent glass.
  • this ice 18 is included in the Dewar device, that is to say it participates in the formation of this device 10, it then comprises internal and external walls which are also the internal and external walls 12a, 12b of the Dewar device 10 between which walls 12a, 12b is therefore also defined an empty or quasi-empty space 16.
  • the partition part of the watch case 6 when the partition part of the watch case 6, the middle part, the crystal and the back participate in forming the Dewar device, then the internal and external walls of this partition part, of this middle part, of the crystal and the back are also the inner and outer walls 12a, 12b of the Dewar device 10 of this watch 2. It is therefore understood that these inner and outer walls of the partitioning part, the middle part, the crystal and the back then participate in together form the inner and outer walls 12a, 12b of the Dewar device 10.
  • Such a Dewar device 10 thus provides the watch 2 with very good thermal insulation vis-à-vis the external environment by preventing the heat present on the outside of the watch 2 from being transmitted inside the watch. space 14 by radiation.
  • the temperature outside the watch 2 reaches extreme values, typically of the order of -125 to +125 ° C
  • the temperature inside the encapsulation space 14 remains substantially equal to the temperature of the ambient medium in which the encapsulation was carried out, typically of the order of 20 ° C. It can thus be seen that such a configuration makes it possible to protect the electrical or electronic components 8a-8g of the watch 2, and thus to allow their operation under extreme outside temperature conditions.
