Definitions

  • the invention relates to a clockwork resonator mechanism, comprising a structure and an anchoring block from which at least one inertial element is suspended, a virtual pivot comprising a plurality of substantially longitudinal elastic blades, each fixed, at a first end to said anchoring block, and at a second end to said inertial element.
  • the invention also relates to a clockwork movement comprising at least one such resonator mechanism.
  • the invention relates to the field of clock resonators, and in particular those which comprise elastic blades acting as return means for the operation of the oscillator.
  • the torsional rigidity of the suspension is a delicate point for most watch oscillators with at least one spiral spring or elastic blades constituting a flexible guide, and in particular for crossed blade resonators. And shock resistance also depends on this torsional rigidity; in fact, during impacts, the stress undergone by the blades quickly reaches very high values, which reduces the travel that the part can travel before giving way. Shock absorbers for watch parts are available in many variants. However, their main purpose is to protect the fragile pivots of the resonator axis, and not the elastic elements, such as the classical spiral spring.
  • New mechanism architectures allow to maximize the quality factor of a resonator, by the use of flexible guidance with the use of an anchor escapement with a very small lift angle, according to the demand CH15442016 on behalf of ETA Manufacture Horlogère Suisse and its derivatives, the teachings of which can be directly used in this invention, and whose resonator can still be improved with regard to its sensitivity to shocks, in certain particular directions. It is therefore a question of protecting the blades from breaking in the event of shocks.
  • the invention proposes to improve the demand resonator mechanism CH715526 or the request EP3561607 on behalf of ETA Manufacture Horlogère Suisse to protect the flexible suspension from the disadvantages mentioned above.
  • the invention relates to a clockwork resonator mechanism, comprising a structure and an anchoring block from which is suspended at least one inertial element arranged to oscillate according to a first degree of freedom in rotation RZ around a pivot axis extending in a first direction Z, said inertial element being subjected to return forces exerted by a virtual pivot comprising a plurality of substantially longitudinal elastic blades, each fixed, at a first end to said anchoring block, and at a second end to said inertial element, each said elastic blade being deformable essentially in an XY plane perpendicular to said first direction Z, said anchoring block being suspended from said structure by a flexible suspension arranged to allow the mobility of said anchoring block.
  • the resonator mechanism comprises a viscous substance arranged at least in part around the flexible suspension, the viscous substance being configured to dissipate at least in part the energy due to a shock, the viscous substance being a deformable material sufficiently strong to avoid flowing, and which adheres to the walls of the flexible suspension.
  • said flexible suspension comprises, between said anchoring block and a first intermediate mass, which is fixed to said structure directly or by means of a plate flexible in said first direction Z, a transverse translation table with flexible guidance and comprising at least two transverse flexible blades or rods, preferably rectilinear, and extending in said second direction X and in symmetry around a transverse axis crossing said pivot axis.
  • the viscous substance is arranged at least partly around the second intermediate mass.
  • the anchoring block is movable according to five flexible degrees of freedom of the suspension which are a first degree of freedom in translation according to said first direction Z, a second degree of freedom in translation according to a second direction X orthogonal to said first direction Z, a third degree of freedom in translation according to a third direction Y orthogonal to said second direction X and to said first direction Z, a second degree of freedom in rotation RX around an axis extending according to said second direction X, and a third degree of freedom in rotation RY around an axis extending according to said third direction YX
  • this resonator mechanism 100 of clockwork comprises a structure 1 and an anchoring block 30, from which is suspended at least one inertial element 2 arranged to oscillate according to a first degree of freedom in rotation RZ around a pivot axis D extending in a first direction Z.
  • the inertial element 2 comprises a balance 20.
  • the balance has a bone shape, the balance comprising a straight segment provided with a bulb at each end.
  • Each bulb may comprise small weights 29 to adjust the inertia of the inertial element 2.
  • This inertial element 2 is subjected to return forces exerted by a virtual pivot 200 comprising a plurality of substantially longitudinal elastic blades 3, each fixed, at a first end to the anchoring block 30, and at a second end to the inertial element 2.
  • Each elastic blade 3 is deformable essentially in an XY plane perpendicular to the first direction Z.
  • the principle is to use the torsional flexibility of a translation table to better manage the torsional rigidities of the suspension.
  • the blades of the XY tables are oriented so that the direction of greatest torsional flexibility is aimed at the axis of rotation of the resonator. Their torsional flexibility is managed by bringing the blades closer together.
  • the flexible suspension 300 comprises, between the anchoring block 30 and a first intermediate mass 303, which is fixed to the structure 1 directly or by means of a flexible plate 301 in the first direction Z, a transverse translation table 32 with flexible guidance, and which comprises transverse blades 320 or transverse flexible rods, rectilinear and extending in the second direction X.
  • the flexible suspension 300 also comprises, between the anchoring block 30 and a second intermediate mass 305, a longitudinal translation table 31 with flexible guidance, and which comprises longitudinal blades 310 or longitudinal flexible rods, rectilinear and extending in the third direction Y. And, between the second intermediate mass 305 and the first intermediate mass 303, the transverse translation table 32 with flexible guidance comprises transverse blades 320 or transverse flexible rods, rectilinear and extending in the second direction X.

  • the transverse translation table 32 comprises at least two transverse flexible blades or rods, parallel to each other and of the same length.
  • figures 1 to 4 illustrate a non-limiting variant with four parallel transverse blades, and, more particularly, each consisting of two half-blades arranged on two superimposed levels, and extending in the extension of one another in the first direction Z.
  • These half-blades can be, either entirely free relative to one another, or secured by gluing or the like, or by growth of SiO 2 in the case of a silicon execution, or the like.
  • the longitudinal translation table 31, when it exists since it is optional, can obey the same construction principle.
  • the number, arrangement, and section of these blades or rods can vary without departing from the present invention.
  • the principle is to use the torsional flexibility of a translation table to better manage the torsional rigidities of the suspension.

  • figures 1 to 4 illustrate a non-limiting variant with four parallel transverse blades, and, more particularly, each consisting of two half-blades arranged on two superimposed levels, and extending in the extension of one another in the first direction Z. These half-blades can be, either entirely free relative to one another, or secured by gluing or the like, or by growth of SiO 2 in the case of a silicon execution, or the like.

More particularly, the transverse blades or rods of the transverse translation table 32 have a first plane of symmetry, which is parallel to the transverse axis D2, and which passes through the pivot axis D.
