Definitions

  • the invention relates to a timepiece resonator mechanism comprising a first support with a first anchor and a second anchor to which is fixed a flexible pivoting guide mechanism, which defines a virtual pivot axis about which rotates a pivoting mass, and which comprises at least one anterior RCC flexible pivot and a posterior RCC flexible pivot mounted in series and head to tail with respect to each other about said virtual pivot axis, said prior RCC flexible pivot comprising, between said first support and an intermediate rotatable support, two straight anterior flexible blades of the same anterior length between their recesses, defining two anterior linear directions which intersect at said virtual pivot axis and which define with said virtual pivot axis an anterior angle, and whose respective anchorages of said two most straight forward flexible blades away from said virtual pivot axis are both at the same previous distance from said virtual pivot axis, and said posterior flexible pivot RCC having, between said intermediate rotary support, which comprises a third anchor and a fourth anchor, and said pivoting mass, two straight posterior flexible blades having the same posterior length between their rece
  • the invention also relates to a watch movement comprising at least one such resonator mechanism.
  • the invention also relates to a watch comprising at least one such movement.
  • the invention relates to the field of clock resonator mechanisms.
  • the use of a flexible guiding pivot makes it possible to replace the real pivot of a balance and the spiral spring of elastic return. This has the advantage of eliminating the friction of pivots.
  • the flexible guide pins are known to have a non-linear elastic restoring force which makes the resonator anisochronous, that is to say that the frequency depends on the amplitude of the oscillation, and to have a movement parasite of the instantaneous axis of rotation, which makes the movement of the resonator sensitive to its position in the field of gravity.
  • the invention proposes to produce a mechanical resonator with a high quality factor using an inertial part such as a rocker, supported by a guide with flexible blades in rotation, also called flexible guide pin, which also acts as a means of elastic return. It is desired that this resonator is isochronous (independent of amplitude) and insensitive to positions in the gravitational field (position independent).
  • the invention seeks to combine the advantages of two known two-dimensional and three-dimensional geometries, in a simple and economical, therefore two-dimensional, execution.
  • the invention thus relates to a clock resonator mechanism according to claim 1.
  • the invention also relates to a watch movement comprising at least one such resonator mechanism.
  • the invention also relates to a watch comprising at least one such movement.
  • the invention relates to a timepiece resonator mechanism 1000, comprising a first rigid support 100, fixed or mobile, with a first anchor 1 and a second anchor 2, to which is fixed a flexible pivoting guide mechanism 10, which defines a virtual pivot axis A, about which rotates a rigid pivoting mass 200 rotatively.
  • This flexible pivot guide mechanism 10 is a 2D flexible guide pivot, that is to say, achievable in a plane.
  • This flexible pivoting guide mechanism 10 allows the rigid pivoting mass 200 to rotate the virtual pivot axis A relative to the first rigid support 100. It is composed of two flexible pivots RCC (Remote Center Compliance, that is to say, center of rotation offset) whose axes of rotation coincide and which are connected by a rigid intermediate rotating support 20. The two RCC pivots are thus put in series, but head to tail with respect to each other, so that their parasitic movements compensate each other.
  • RCC Remote Center Compliance
  • the flexible pivotal guide mechanism 10 includes an earlier RCC flexible pivot 10A and a rearward flexible RCC pivot 10P, which are connected in series with each other, and head-to-tail, about the pivot axis virtual A common, and which incorporate elastic flexible elements.
  • the front flexible pivot RCC 10A comprises, between the first support 100 and an intermediate rotary support 20, two anterior resilient assemblies 11, 21, formed, in the embodiment of the figures, by two straight forward flexible blades 110, 210, and the like.
  • the rear flexible pivot RCC 10P comprises, between the intermediate rotary support 20, which comprises a third anchorage 3 and a fourth anchorage 4, and the pivoting mass 200, two rear elastic assemblies 31, 41, formed in the embodiment of the figures, by two right posterior flexible blades 310, 410 having the same posterior length LP between their recesses, defining two posterior linear directions D3, D4, which intersect at the level of the virtual pivot axis A, and which define with this virtual pivot axis A a ⁇ P posterior angle, and whose respective anchors of the two posterior flexible blades straight 310, 410, the farthest from the virtual pivot axis A are both at the same rear distance DP of the virtual pivot axis A.
  • the flexible pivoting guide mechanism 10 is planar.
  • the invention consists in optimizing the angle between the elastic elements of each flexible pivot RCC, so that the pivot has a linear elastic return force, so that the mechanical resonator is isochronous in a given range of angular amplitude.
  • the front angle ⁇ A and the posterior angle ⁇ P are equal to a common angle ⁇ . More particularly, this common angle ⁇ is close to 112.0 °.
  • the anterior distance DA and the posterior distance DP are equal to a common distance D
  • the anterior length LA and the posterior length LP are equal to a common length L.
  • the common angle ⁇ is then between: 109.5 + 5 / D / The - 2 / 3 and 114.5 + 5 / D / The - 2 / 3 .
  • the figure 5 shows the evolution of the optimal angle ⁇ , as a function of the D / L ratio.
  • first anterior elastic assembly 11, the second anterior elastic assembly 21, the first posterior elastic assembly 31, and the second posterior elastic assembly 41 each comprise at least one straight flexible blade 110, 210, 310, 410, or a bundle of parallel straight flexible blades, not shown to avoid complicating the figures.
  • the first anterior elastic assembly 11, the second anterior elastic assembly 21, the first posterior elastic assembly 31, and the second posterior elastic assembly 41 each consist of a straight flexible blade 110,210,310,410.
  • first anterior elastic assembly 11, the second anterior elastic assembly 21, the first posterior elastic assembly 31, and the second posterior elastic assembly 41 each comprise an alternation of straight flexible blades and elements. intermediates more rigid than these straight flexible blades, aligned in the respective directions D1, D2, D3, D4.
  • an inertial element 201 to the pivoting mass 200, or to integrate it therewith, and to fix the first rigid support 100 to a plate or a bridge of the watch movement, or any other element that can act as a support for the flexible pivot resonator, for example, without limitation, a tuning element of a tuning fork, or an anti-shock element which is authorized to move only in the event of a violent impact, so as to reduce the acceleration experienced by the resonator.
  • the fixed part and the moving part represented here are permutable.
  • This inertial element can be a disk, a ring such as a beam serge as visible on the figure 2 , or a simple arm as visible on the figure 1 . It is important that the center of mass of the inertial element is substantially aligned with the virtual pivot axis A.
  • the elastic elements comprise intermediate elements that are stiffer than the straight flexible blades, these intermediate elements are advantageously also skeletonized.
  • Another advantageous variant consists of arranging the rigid parts 100, 20, 200, very close to each other around the virtual pivot axis A, so that they act as anti-shock, radial or / and angular abutments, in order to prevent a rupture of the blades, as visible with the surfaces 105, 25, 26, 206, 28, 208, of the figure 4 , in particular the oblique faces 28 and 208 which contribute greatly to the impact resistance of the system.
  • the arrangement of the most rigid parts comprises limiting surfaces 101, 102, 203, 204 arranged to limit the flexible blades, as visible on the figure 4 .
  • the invention can be implemented with blades having other geometries, for example in zig-zag or serpentine or with curved parts, but it is clear that the geometry of straight blades strongly limits the possible parasitic displacements of the virtual pivot axis A, and remains the most advantageous mode of implementation of the invention.
  • the blades may, again, have varying thicknesses.
  • the essential thing is to respect the symmetry of flexibility with respect to the bisector of the angle ⁇ A, and with respect to the virtual pivot axis A.
  • the invention is particularly well suited to monolithic execution.
  • the first support 100, the pivoting mass 200, and the flexible pivoting guide mechanism 10 form a one-piece assembly.
  • This one-piece assembly can be produced either by conventional machining, or else, in a particular and non-exhaustive manner, by "MEMS" or "LIGA” type technologies or 3D printing or additive manufacturing by laser or the like, in silicon, quartz , DLC, metal alloys, glass, ruby, sapphire or other ceramic, or polymers, whether charged or not, or the like, thermally compensated, in particular by particular local growth of silicon dioxide, in certain areas of the room arranged for this purpose, when this one-piece assembly is made of silicon.
  • other materials are usable, for some at the cost of temperature compensation. Mention may be made in particular, and not exclusively, of amorphous or crystalline metal alloys.
  • the flexible pivoting guide mechanism 10 is advantageously made of silicon, oxidized in such a way that the complete resonator mechanism 1000, with this reported inertial mass 201, is thermally compensated.
  • the clock resonator mechanism 1000 may comprise a plurality of such flexible pivoting guide mechanisms 10 connected in series, to increase the total angular travel, arranged in parallel planes, and around the same virtual pivot axis A, by joining together rigid parts between them.
  • Such a part can be formed by assembling two pieces engraved on one level, or can be etched in silicon SOI two levels.
  • the invention also relates to a 2000 clockwork movement comprising at least one such resonator mechanism 1000.
  • the invention also relates to a watch 3000 comprising at least one such movement 2000.
