Definitions

  • 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 restoring forces exerted by a flexible 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 element inertial, each said elastic blade being deformable essentially in an XY plane perpendicular to said first direction Z, the structure carrying this anchoring block by a flexible suspension which allows the mobility of the anchoring block according to five degrees of freedom.
  • the invention also relates to a clock oscillator comprising at least one such resonator mechanism.
  • the invention also relates to a timepiece movement comprising at least one such oscillator and/or such a resonator mechanism.
  • the invention also relates to a watch comprising such a clock movement, and/or such an oscillator, and/or such a resonator mechanism.
  • the invention relates to the field of clockwork resonators, and more particularly those which comprise elastic blades acting as return means for the operation of the oscillator, and the shock protection of such mechanisms with flexible guides.
  • clock oscillators comprising elastic blades constituting a flexible guide, and in particular resonators with crossed blades.
  • the use of a pivot with flexible guidance makes it possible to replace the pivot of a balance wheel as well as its spiral spring. This has the advantage of eliminating pivot friction and therefore of increasing the quality factor of the resonator.
  • the inertial mass in particular a pendulum, is suspended from the flexible guide, generally but not limited to silicon, it is necessary to provide an anti-shock device so that the blades do not break during a fall.
  • a way to achieve this shockproof was presented in the application CH 715526 in the name of ETA Manufacture Horlogère Suisse, incorporated here by reference.
  • a flexible structure (called anti-shock) is inserted between the flexible pivot and the plate which authorizes the movements of the balance according to all the degrees of freedom (translations X, Y, Z and rotations X, Y) except the Z rotation of the balance which is authorized by the flexible pivot, and mechanical stops are added to limit the stroke of the balance.
  • this shock absorber allows the balance wheel to move as far as the mechanical stops, while protecting the flexible silicon pivot from breaking.
  • the rigidity of the shock absorber is high enough for the balance wheel not to touch the mechanical stops.
  • the shock absorber and the flexible pivot are made in a single monolithic piece of silicon. This has advantages in terms of simplicity of manufacture and assembly. Nevertheless silicon is a fragile material, so that, during very violent shocks, it can happen that the part breaks because the maximum stress is exceeded.
  • shock absorbers for timepieces come in many variants. However, their main purpose is to protect the fragile pivots of the axle, and not the elastic elements, such as conventionally the spiral spring.
  • the document EP3054357A1 on behalf of ETA Manufacture Horlogère Suisse SA describes a horological oscillator comprising a structure and separate primary resonators, temporally and geometrically out of phase, each comprising a mass returned to the structure by an elastic return means.
  • This oscillator comprises coupling means for the interaction of the primary resonators, comprising motor means for driving a mobile in motion which comprises drive and guide means arranged to drive and guide a control means articulated with transmission means , each articulated, at a distance from the control means, with a mass of a primary resonator.
  • the primary resonators and the mobile are arranged in such a way that the axes of the articulations of any two of the primary resonators and the axis of articulation of the control means are never coplanar.
  • the document EP3035127A1 on behalf of SWATCH GROUP RESEARCH & DEVELOPMENT Ltd describes a clockwork oscillator comprising a resonator constituted by a tuning fork which comprises at least two oscillating mobile parts, fixed to a connecting element by flexible elements whose geometry determines a virtual pivot axis of determined position relative to a plate, and around which the respective mobile part oscillates, the center of mass of which coincides in the rest position with the respective virtual pivot axis.
  • the flexible elements consist of elastic blades crossed at a distance from each other in two parallel planes, the projections of the directions of which on one of the planes parallel intersect at the virtual pivot axis of the moving part.
  • New architectures of mechanisms make it possible to maximize the quality factor of a resonator, by the use of a flexible guide with the use of a lever escapement with a very small angle of lift, according to demand CH01544/16 in the name of ETA Manufacture Horlogère Suisse and its derivatives, the teachings of which can be directly used in the present invention, and whose resonator can be further improved as regards its sensitivity to shocks, in certain particular directions. It is therefore a question of protecting the blades from breaking in the event of impact.
  • Requirement CH00518/18 or request EP18168765.8 on behalf of ETA Manufacture Horlogère Suisse describes a resonator clockwork mechanism, comprising a structure carrying, by a flexible suspension, an anchoring block from which is suspended an inertial element oscillating according to a first degree of freedom in rotation RZ, under the action of return forces exerted by a flexible pivot comprising first elastic blades each fixed to said inertial element and to said anchoring block, the flexible suspension being arranged to allow a certain mobility of the anchoring block according to all the other degrees of freedom that the first degree of freedom in rotation RZ according to which only the inertial element is mobile to avoid any disturbance of its oscillation, and the rigidity of the suspension according to the first degree of freedom in rotation RZ is very greatly greater than the rigidity of the pivot flexible according to this same first degree of freedom in rotation RZ.
  • the invention proposes to optimize the shock protection of such an oscillator, while ensuring the required torsional stiffness of the suspension, in particular for a resonator mechanism according to CH00518/18 or request EP18168765.8 in the name of ETA Manufacture Horlogère Suisse, or for a similar resonator with flexible guides.
  • a good rotary resonator with flexible guidance which constitutes a flexible pivot and defines a virtual pivot axis, must be both very flexible for the rotation of oscillation according to a first degree of freedom in rotation RZ, and also very rigid according to the other degrees of freedom (X, Y, Z, RX, RY) so as to avoid parasitic movements of the center of mass of the resonator. Indeed, such parasitic movements can cause walking errors, if the orientation of the resonator changes in the field of gravity (one speaks of position error).
  • the suspension of the embedding of the pivot must be very rigid according to the degree of freedom of the oscillation, so as not to disturb the isochronism of the resonator, and so as not to dissipate energy via movements due to the reaction forces.
  • the invention proposes to produce an improved shock absorber for an oscillator with flexible guidance, to better manage the torsion rigidities of the suspension, and consequently to limit the out-of-plane displacement stroke of the blades of a blade resonator, and therefore ensure better performance of the system

  • a high G toughness means that the part is able to store more elastic energy before breaking.
  • the value of the second toughness G2 is greater than ten times the value of the first toughness G1. More particularly still, the value of the second tenacity G2 is greater than eighty times the value of the first tenacity G1. This is the case when the first material is silicon and/or a silicon oxide, and when the second material is NiP, the G2/G1 ratio is close to 100;

It is therefore important to ensure that the Hertzian pressure does not exceed the maximum stress at contact between the jaw 939 and the relief 309 of the anchoring block 30 made of silicon. For this reason, the shape of the jaw 939 marries that of relief 309, so that the difference in radius of curvature is as small as possible.
