Description

Domaine de l'inventionField of the invention

L'invention concerne un mécanisme résonateur d'horlogerie, comportant une structure et un bloc d'ancrage auquel est suspendu au moins un élément inertiel, un pivot virtuel comportant une pluralité de lames élastiques sensiblement longitudinales, chacune fixée, à une première extrémité audit bloc d'ancrage, et à une deuxième extrémité audit élément inertiel.The invention relates to a clockwork resonator mechanism, comprising a structure and an anchoring block from which is suspended at least one inertial element, a virtual pivot comprising a plurality of substantially longitudinal elastic blades, each fixed, at a first end to said block anchor, and at a second end to said inertial element.

L'invention concerne encore un mouvement d'horlogerie comportant au moins un tel mécanisme résonateur.The invention also relates to a clock movement comprising at least one such resonator mechanism.

L'invention concerne le domaine des résonateurs d'horlogerie, et tout particulièrement ceux qui comportent des lames élastiques faisant fonction de moyens de rappel pour la marche de l'oscillateur.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.

Arrière-plan de l'inventionBackground of the invention

La rigidité en torsion de la suspension est un point délicat pour la plupart des oscillateurs d'horlogerie comportant au moins un ressort spiral ou des lames élastiques constituant un guidage flexible, et notamment pour les résonateurs à lames croisées. Et la tenue au chocs dépend aussi de cette rigidité en torsion ; en effet, lors de chocs, la contrainte subie par les lames atteint rapidement des valeurs très importantes, ce qui réduit d'autant la course que peut parcourir la pièce avant de céder. Les amortisseurs de chocs pour les pièces d'horlogerie se déclinent dans de nombreuses variantes. Cependant, ils ont essentiellement pour but de protéger les pivots fragiles de l'axe du résonateur, et non pas les éléments élastiques, tel que classiquement le ressort spiral.The torsion rigidity of the suspension is a delicate point for most clock oscillators comprising at least one spiral spring or elastic blades constituting a flexible guide, and in particular for resonators with crossed blades. And the shock resistance also depends on this torsional rigidity; in fact, during shocks, the stress undergone by the blades quickly reaches very high values, which correspondingly reduces the travel that the part can travel before yielding. Shock absorbers for timepieces come in many variants. However, their main purpose is to protect the fragile pivots of the axis of the resonator, and not the elastic elements, such as conventionally the spiral spring.

De nouvelles architectures de mécanismes permettent de maximiser le facteur de qualité d'un résonateur, par l'utilisation d'un guidage flexible avec l'utilisation d'un échappement à ancre avec un très petit angle de levée, selon la demande CH15442016 au nom de ETA Manufacture Horlogère Suisse et ses dérivées, dont les enseignements sont directement utilisables dans la présente invention, et dont le résonateur peut encore être amélioré en ce qui concerne sa sensibilité aux chocs, selon certaines directions particulières. Il s'agit donc de protéger les lames de la rupture en cas de chocs. On se rend compte que les systèmes antichocs proposés à ce jour pour les résonateurs à guidages flexibles, protègent les lames de chocs dans certaines directions seulement, mais pas dans toutes les directions, ou alors qu'ils présentent le défaut de laisser bouger légèrement l'encastrement du pivot virtuel selon sa rotation d'oscillation, ce qui est à éviter autant que possible.New mechanism architectures 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 CH15442016 on behalf of ETA Manufacture Horlogère Suisse and its derivatives, the lessons of which can be directly used in this 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. We realize that the anti-shock systems proposed to date for resonators with flexible guides, protect the shock blades in certain directions only, but not in all directions, or else they have the defect of letting the embedding of the virtual pivot according to its rotation of oscillation, which is to be avoided as much as possible.

La demande CH5182018 ou la demande EP18168765 au nom de ETA Manufacture Horlogère Suisse décrit un mécanisme résonateur d'horlogerie, comportant une structure portant, par une suspension flexible, un bloc d'ancrage auquel est suspendu un élément inertiel oscillant selon un premier degré de liberté en rotation RZ, sous l'action d'efforts de rappel exercés par un pivot virtuel comportant des premières lames élastiques chacune fixée audit élément inertiel et audit bloc d'ancrage, la suspension flexible étant agencée pour autoriser une certaine mobilité du bloc d'ancrage selon tous les degrés de liberté autres que le premier degré de liberté en rotation RZ selon lequel seul est mobile l'élément inertiel pour éviter toute perturbation de son oscillation, et la rigidité de la suspension selon le premier degré de liberté en rotation RZ est très fortement supérieure à la rigidité du pivot virtuel selon ce même premier degré de liberté en rotation RZ.Requirement CH5182018 or request EP18168765 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 virtual 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 virtual according to this same first degree of freedom in rotation RZ.

La demande CH715526 ou la demande EP3561607 au nom de ETA Manufacture Horlogère Suisse décrit un mécanisme résonateur d'horlogerie, comportant une structure et un bloc d'ancrage auquel est suspendu au moins un élément inertiel agencé pour osciller selon un premier degré de liberté en rotation RZ autour d'un axe de pivotement s'étendant selon une première direction Z, ledit élément inertiel étant soumis à des efforts de rappel exercés par un pivot virtuel comportant une pluralité de lames élastiques sensiblement longitudinales, chacune fixée, à une première extrémité audit bloc d'ancrage, et à une deuxième extrémité audit élément inertiel, chaque dite lame élastique étant déformable essentiellement dans un plan XY perpendiculaire à ladite première direction Z.Requirement CH715526 or request EP3561607 on behalf of ETA Manufacture Horlogère Suisse describes a resonator clockwork 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 an axis of pivot extending in a first direction Z, said inertial element being subjected to restoring 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.

Cependant, il arrive que ce soit une ou des lames de la suspension flexible, qui se brisent lors d'un choc important, ou qu'elles s'usent prématurément jusqu'à une probable rupture suite à une série de petits chocs. En effet, la suspension flexible évite la rupture du pivot virtuel, mais elle subit le choc à sa place.However, it happens that it is one or several blades of the flexible suspension, which break during a major shock, or that they wear prematurely until a probable rupture following a series of small shocks. Indeed, the flexible suspension avoids the rupture of the virtual pivot, but it undergoes the shock in its place.

Résumé de l'inventionSummary of the invention

L'invention se propose d'améliorer le mécanisme résonateur de la demande CH715526 ou la demande EP3561607 au nom de ETA Manufacture Horlogère Suisse pour protéger la suspension flexible des inconvénients cités précédemment.The invention proposes to improve the resonator mechanism of the demand CH715526 or request EP3561607 on behalf of ETA Manufacture Horlogère Suisse to protect the flexible suspension from the disadvantages mentioned above.

À cette fin, l'invention se rapporte à un mécanisme résonateur d'horlogerie, comportant une structure et un bloc d'ancrage auquel est suspendu au moins un élément inertiel agencé pour osciller selon un premier degré de liberté en rotation RZ autour d'un axe de pivotement s'étendant selon une première direction Z, ledit élément inertiel étant soumis à des efforts de rappel exercés par un pivot virtuel comportant une pluralité de lames élastiques sensiblement longitudinales, chacune fixée, à une première extrémité audit bloc d'ancrage, et à une deuxième extrémité audit élément inertiel, chaque dite lame élastique étant déformable essentiellement dans un plan XY perpendiculaire à ladite première direction Z, ledit bloc d'ancrage étant suspendu à ladite structure par une suspension flexible agencée pour autoriser la mobilité dudit bloc d'ancrage.To this end, 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 along a first direction Z, said inertial element being subjected to restoring forces exerted by a virtual pivot comprising a plurality of substantially longitudinal elastic blades, each fixed, at a first end to said anchor 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 anchor block being suspended from said structure by a flexible suspension arranged to allow the mobility of said anchor block .

L'invention est remarquable en ce que le mécanisme résonateur comporte une substance visqueuse agencée au moins en partie autour de la suspension flexible, la substance visqueuse étant configurée pour dissiper au moins en partie l'énergie due à un choc.The invention is remarkable in that the resonator mechanism comprises a viscous substance arranged at least partly around the flexible suspension, the viscous substance being configured to dissipate at least partly the energy due to an impact.

Grâce à la substance visqueuse, la suspension flexible est mieux protégée en cas de choc important, notamment pour éviter que la suspension flexible, notamment une des lames ou tiges, ne se brise ou ne se fissure prématurément. Ainsi, on a une double protection, une première protection pour les lames du pivot virtuel grâce à la suspension flexible, et une deuxième protection pour la suspension flexible par la substance visqueuse. Par conséquent, l'invention améliore la protection du mécanisme résonateur contre le risque de casse.Thanks to the viscous substance, the flexible suspension is better protected in the event of a major shock, in particular to prevent the flexible suspension, in particular one of the strips or rods, from breaking or cracking prematurely. Thus, there is a double protection, a first protection for the blades of the virtual pivot thanks to the flexible suspension, and a second protection for the flexible suspension by the viscous substance. Consequently, the invention improves the protection of the resonator mechanism against the risk of breakage.

L'invention concerne un mécanisme résonateur d'horlogerie, qui constitue une variante des résonateurs décrits dans la demande CH5182018 ou la demande EP18168765 au nom de ETA Manufacture Horlogère Suisse, incorporées ici par référence, et dont l'homme du métier saura combiner les caractéristiques avec celles propres à la présente invention. Représenté sur les figures 1 à 4, ce mécanisme résonateur 100 d'horlogerie comporte une structure 1 et un bloc d'ancrage 30, auquel est suspendu au moins un élément inertiel 2 agencé pour osciller selon un premier degré de liberté en rotation RZ autour d'un axe de pivotement D s'étendant selon une première direction Z. L'élément inertiel 2 comprend un balancier 20. Le balancier a une forme d'os, le balancier comprenant un segment droit muni d'un bulbe à chaque extrémité. Chaque bulbe peut comporter des petites masselottes 29 pour régler l'inertie de l'élément inertiel 2. Cet élément inertiel 2 est soumis à des efforts de rappel exercés par un pivot virtuel 200 comportant une pluralité de lames élastiques 3 sensiblement longitudinales, chacune fixée, à une première extrémité au bloc d'ancrage 30, et à une deuxième extrémité à l'élément inertiel 2. Chaque lame élastique 3 est déformable essentiellement dans un plan XY perpendiculaire à la première direction Z.The invention relates to a clockwork resonator mechanism, which constitutes a variant of the resonators described in the application CH5182018 or request EP18168765 in the name of ETA Manufacture Horlogère Suisse, incorporated here by reference, and whose characteristics the person skilled in the art will know how to combine with those specific to the present invention. Represented on figures 1 to 4 , this clockwork resonator mechanism 100 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 about a pivot axis D s extending in a first direction Z. The inertial element 2 comprises a balance 20. The balance has the shape of a bone, the balance comprising a straight segment provided with a bulb at each end. Each bulb may include small flyweights 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 anchor 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.

Le bloc d'ancrage 30 est suspendu à la structure 1 par une suspension flexible 300, qui est agencée pour autoriser la mobilité du bloc d'ancrage 30 selon cinq degrés de liberté flexibles de la suspension qui sont :

  • un premier degré de liberté en translation selon la première direction Z,
  • un deuxième degré de liberté en translation selon une deuxième direction X orthogonale à la première direction Z,
  • un troisième degré de liberté en translation selon une troisième direction Y orthogonale à la deuxième direction X et à la première direction Z,
  • un deuxième degré de liberté en rotation RX autour d'un axe s'étendant selon la deuxième direction X, et
  • un troisième degré de liberté en rotation RY autour d'un axe s'étendant selon la troisième direction Y.
The anchor block 30 is suspended from the structure 1 by a flexible suspension 300, which is arranged to allow the mobility of the anchor block 30 according to five flexible degrees of freedom of the suspension which are:
  • a first degree of freedom in translation along the first direction Z,
  • a second degree of freedom in translation along a second direction X orthogonal to the first direction Z,
  • a third degree of freedom in translation along a third direction Y orthogonal to the second direction X and to the first direction Z,
  • a second degree of freedom in rotation RX around an axis extending along the second direction X, and
  • a third degree of freedom in rotation RY around an axis extending along the third direction Y.

Le principe est d'utiliser la souplesse en torsion d'une table de translation pour mieux gérer les rigidités en torsion de la suspension. Pour ce faire, on oriente les lames des tables XY de manière à ce que la direction de plus grande flexibilité en torsion vise l'axe de rotation du résonateur. On gère leur souplesse en torsion en rapprochant les lames les unes des autres.The principle is to use the torsional flexibility of a translation table to better manage the torsional stiffness of the suspension. To do this, the blades of the XY tables are oriented so that the direction of greatest flexibility in torsion aims at the axis of rotation of the resonator. Their flexibility in torsion is managed by bringing the blades closer to each other.

Ainsi, la suspension flexible 300 comporte, entre le bloc d'ancrage 30 et une première masse intermédiaire 303, laquelle est fixée à la structure 1 directement ou par l'intermédiaire d'une plaque 301 flexible selon la première direction Z, une table de translation transversale 32 à guidage flexible, et qui comporte des lames transversales 320 ou des tiges flexibles transversales, rectilignes et s'étendant selon la deuxième direction X.Thus, the flexible suspension 300 comprises, between the anchor block 30 and a first intermediate mass 303, which is fixed to the structure 1 directly or via a flexible plate 301 in the first direction Z, a table of transverse translation 32 with flexible guidance, and which comprises transverse blades 320 or transverse flexible rods, rectilinear and extending in the second direction X.

Dans une réalisation particulière non limitative, et tel qu'illustré par les figures, la suspension flexible 300 comporte encore, entre le bloc d'ancrage 30 et une deuxième masse intermédiaire 305, une table de translation longitudinale 31 à guidage flexible, et qui comporte des lames longitudinales 310 ou des tiges flexibles longitudinales, rectilignes et s'étendant selon la troisième direction Y. Et, entre la deuxième masse intermédiaire 305 et la première masse intermédiaire 303, la table de translation transversale 32 à guidage flexible comporte des lames transversales 320 ou des tiges flexibles transversales, rectilignes et s'étendant selon la deuxième direction X.In a particular non-limiting embodiment, and as illustrated by the figures, the flexible suspension 300 further comprises, between the anchor 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 along 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 along the second direction X.

Plus particulièrement, l'axe longitudinal D1 croise l'axe transversal D2, et en particulier l'axe longitudinal D1, l'axe transversal D2, et l'axe de pivotement D sont concourants.More particularly, the longitudinal axis D1 crosses the transverse axis D2, and in particular the longitudinal axis D1, the transverse axis D2, and the pivot axis D are concurrent.

De façon plus particulière, la table de translation longitudinale 31 et la table de translation transversale 32 comportent chacune au moins deux lames ou tiges flexibles, chaque lame ou tige étant caractérisée par son épaisseur selon la deuxième direction X quand la lame ou tige s'étend selon la troisième direction Y ou inversement, par sa hauteur selon la première direction Z, et par sa longueur selon la direction selon laquelle s'étend la lame ou tige, la longueur étant par exemple au moins cinq fois plus grande que la hauteur, la hauteur étant au moins aussi grande que l'épaisseur, et plus particulièrement au moins cinq fois plus grande que cette épaisseur, et plus particulièrement encore au moins sept fois plus grande que cette épaisseur.More particularly, the longitudinal translation table 31 and the transverse translation table 32 each comprise at least two blades or flexible rods, each blade or rod being characterized by its thickness according to the second direction X when the blade or rod extends in the third direction Y or vice versa, by its height in the first direction Z, and by its length in the direction in which the blade or rod extends, the length being for example at least five times greater than the height, the height being at least as great as the thickness, and more particularly at least five times greater than this thickness, and more particularly still at least seven times greater than this thickness.

Plus particulièrement, la table de translation transversale 32 comporte au moins deux lames ou tiges flexibles transversales, parallèles entre elles et de même longueur. Les figures 1 à 4 illustrent une variante non limitative avec quatre lames transversales parallèles, et, plus particulièrement, chacune constituée de deux demi-lames agencées sur deux niveaux superposées, et s'étendant dans le prolongement l'une de l'autre selon la première direction Z. Ces demi-lames peuvent être, ou bien entièrement libres l'une par rapport à l'autre, ou bien solidarisées par collage ou similaire, ou par croissance de SiO2 dans le cas d'une exécution en silicium, ou similaire. Naturellement, la table de translation longitudinale 31, quand elle existe puisqu'elle est facultative, peut obéir au même principe de construction. Le nombre, la disposition, et la section de ces lames ou tiges, peuvent varier sans s'écarter de la présente invention.More particularly, the transverse translation table 32 comprises at least two blades or transverse flexible rods, parallel to each other and of the same length. The 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 may be either entirely free relative to each other, or else secured by bonding or the like, or by growth of SiO 2 in the case of an execution in silicon, or the like. Naturally, the longitudinal translation table 31, when it exists since it is optional, can obey the same principle of construction. The number, arrangement and section of these blades or rods may vary without departing from the present invention.

Le principe est d'utiliser la souplesse en torsion d'une table de translation pour mieux gérer les rigidités en torsion de la suspension. Pour ce faire, on oriente les lames des tables XY de manière à ce que la direction de plus grande flexibilité en torsion vise l'axe de rotation du résonateur. On gère leur souplesse en torsion en rapprochant les lames les unes des autres.The principle is to use the torsional flexibility of a translation table to better manage the torsional stiffness of the suspension. To do this, the blades of the XY tables are oriented so that the direction of greatest flexibility in torsion aims at the axis of rotation of the resonator. Their flexibility in torsion is managed by bringing the blades closer to each other.

Ainsi, la suspension flexible 300 comporte, entre le bloc d'ancrage 30 et une première masse intermédiaire 303, laquelle est fixée à la structure 1 directement ou par l'intermédiaire d'une plaque 301 flexible selon la première direction Z, une table de translation transversale 32 à guidage flexible, et qui comporte des lames transversales 320 ou des tiges flexibles transversales, rectilignes et s'étendant selon la deuxième direction X.Thus, the flexible suspension 300 comprises, between the anchor block 30 and a first intermediate mass 303, which is fixed to the structure 1 directly or via a flexible plate 301 in the first direction Z, a table of transverse translation 32 with flexible guidance, and which comprises transverse blades 320 or transverse flexible rods, rectilinear and extending in the second direction X.

Dans une réalisation particulière non limitative, et tel qu'illustré par les figures, la suspension flexible 300 comporte encore, entre le bloc d'ancrage 30 et une deuxième masse intermédiaire 305, une table de translation longitudinale 31 à guidage flexible, et qui comporte des lames longitudinales 310 ou des tiges flexibles longitudinales, rectilignes et s'étendant selon la troisième direction Y. Et, entre la deuxième masse intermédiaire 305 et la première masse intermédiaire 303, la table de translation transversale 32 à guidage flexible comporte des lames transversales 320 ou des tiges flexibles transversales, rectilignes et s'étendant selon la deuxième direction X.In a particular non-limiting embodiment, and as illustrated by the figures, the flexible suspension 300 further comprises, between the anchor block 30 and a second intermediate mass 305, a longitudinal translation table 31 to flexible guide, and which comprises longitudinal blades 310 or longitudinal flexible rods, rectilinear and extending along the third direction Y. And, between the second intermediate mass 305 and the first intermediate mass 303, the transverse translation table 32 with flexible comprises transverse blades 320 or transverse flexible rods, rectilinear and extending in the second direction X.

Plus particulièrement, l'axe longitudinal D1 croise l'axe transversal D2, et en particulier l'axe longitudinal D1, l'axe transversal D2, et l'axe de pivotement D sont concourants.More particularly, the longitudinal axis D1 crosses the transverse axis D2, and in particular the longitudinal axis D1, the transverse axis D2, and the pivot axis D are concurrent.

De façon plus particulière, la table de translation longitudinale 31 et la table de translation transversale 32 comportent chacune au moins deux lames ou tiges flexibles, chaque lame ou tige étant caractérisée par son épaisseur selon la deuxième direction X quand la lame ou tige s'étend selon la troisième direction Y ou inversement, par sa hauteur selon la première direction Z, et par sa longueur selon la direction selon laquelle s'étend la lame ou tige, la longueur étant par exemple au moins cinq fois plus grande que la hauteur, la hauteur étant au moins aussi grande que l'épaisseur, et plus particulièrement au moins cinq fois plus grande que cette épaisseur, et plus particulièrement encore au moins sept fois plus grande que cette épaisseur.More particularly, the longitudinal translation table 31 and the transverse translation table 32 each comprise at least two blades or flexible rods, each blade or rod being characterized by its thickness in the second direction X when the blade or rod extends in the third direction Y or vice versa, by its height in the first direction Z, and by its length in the direction in which the blade or rod extends, the length being for example at least five times greater than the height, the height being at least as great as the thickness, and more particularly at least five times greater than this thickness, and more particularly still at least seven times greater than this thickness.

Plus particulièrement, la table de translation transversale 32 comporte au moins deux lames ou tiges flexibles transversales, parallèles entre elles et de même longueur. Les figures 1 à 4 illustrent une variante non limitative avec quatre lames transversales parallèles, et, plus particulièrement, chacune constituée de deux demi-lames agencées sur deux niveaux superposées, et s'étendant dans le prolongement l'une de l'autre selon la première direction Z. Ces demi-lames peuvent être, ou bien entièrement libres l'une par rapport à l'autre, ou bien solidarisées par collage ou similaire, ou par croissance de SiO2 dans le cas d'une exécution en silicium, ou similaire. Naturellement, la table de translation longitudinale 31, quand elle existe puisqu'elle est facultative, peut obéir au même principe de construction. Le nombre, la disposition, et la section de ces lames ou tiges, peuvent varier sans s'écarter de la présente invention. Plus particulièrement, les lames ou tiges transversales de la table de translation transversale 32 ont un premier plan de symétrie, qui est parallèle à l'axe transversal D2, et qui passe par l'axe de pivotement D.More particularly, the transverse translation table 32 comprises at least two blades or transverse flexible rods, parallel to each other and of the same length. The 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 may be either entirely free relative to each other, or else secured by bonding or the like, or by growth of SiO 2 in the case of an execution in silicon, or the like. Naturally, the longitudinal translation table 31, when it exists since it is optional, can obey the same principle of construction. The number, arrangement and section of these blades or rods may vary without departing from the present invention. 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.

Plus particulièrement, les lames ou tiges transversales de la table de translation transversale 32 ont un deuxième plan de symétrie, qui est parallèle à l'axe transversal D2, et orthogonal à l'axe de pivotement D.More particularly, the transverse blades or rods of the transverse translation table 32 have a second plane of symmetry, which is parallel to the transverse axis D2, and orthogonal to the pivot axis D.

Plus particulièrement, les lames ou tiges transversales de la table de translation transversale 32 ont un troisième plan de symétrie, qui est perpendiculaire à l'axe transversal D2, et parallèle à l'axe de pivotement D.More particularly, the blades or transverse rods of the transverse translation table 32 have a third plane of symmetry, which is perpendicular to the transverse axis D2, and parallel to the pivot axis D.

Plus particulièrement, les lames ou tiges transversales de la table de translation transversale 32 s'étendent sur au moins deux niveaux parallèles entre eux, chaque niveau étant perpendiculaire à l'axe de pivotement D.More particularly, the blades or transverse rods of the transverse translation table 32 extend over at least two levels parallel to each other, each level being perpendicular to the pivot axis D.

Plus particulièrement, l'agencement des lames ou tiges transversales de la table de translation transversale 32 est identique sur chacun des niveaux.More particularly, the arrangement of the transverse blades or rods of the transverse translation table 32 is identical on each of the levels.

Plus particulièrement, les lames transversales ou tiges flexibles rectilignes 320, 1320, sont des lames plates dont la hauteur est au moins cinq fois plus grande que leur épaisseur.More particularly, the transverse blades or rectilinear flexible rods 320, 1320 are flat blades whose height is at least five times greater than their thickness.

Plus particulièrement, les lames ou tiges longitudinales de la table de translation longitudinale 31 ont un deuxième plan de symétrie, qui est parallèle à l'axe longitudinal D1, et orthogonal à l'axe de pivotement D.More particularly, the blades or longitudinal rods of the longitudinal translation table 31 have a second plane of symmetry, which is parallel to the longitudinal axis D1, and orthogonal to the pivot axis D.

Plus particulièrement, les lames ou tiges longitudinales de la table de translation longitudinale 31 ont un troisième plan de symétrie, qui est perpendiculaire à l'axe longitudinal D1, et parallèle à l'axe de pivotement D.More particularly, the blades or longitudinal rods of the longitudinal translation table 31 have a third plane of symmetry, which is perpendicular to the longitudinal axis D1, and parallel to the pivot axis D.

Plus particulièrement, l'agencement des lames ou tiges transversales de la table de translation longitudinale 31 est identique sur chacun des niveaux.More particularly, the arrangement of the blades or transverse rods of the longitudinal translation table 31 is identical on each of the levels.

Plus particulièrement, les lames longitudinales ou tiges flexibles rectilignes 310 sont des lames plates dont la hauteur est au moins cinq fois plus grande que leur épaisseur.More particularly, the longitudinal blades or rectilinear flexible rods 310 are flat blades whose height is at least five times greater than their thickness.

Dans une variante, non représenté sur les figures, les lames longitudinales ou tiges flexibles rectilignes 310 sont des tiges de section carrée ou circulaire dont la hauteur égale à l'épaisseur.In a variant, not shown in the figures, the longitudinal strips or rectilinear flexible rods 310 are rods of square or circular cross-section, the height of which is equal to the thickness.

Selon l'invention la suspension flexible 300 comporte une substance visqueuse 10 qui peut être disposée sur une ou plusieurs parties de la suspension flexible 300. Comme le montre les figure 2 et 3, la substance visqueuse 10 est de préférence agencée entre les lames ou tiges flexibles transversales 320 de la table de translation transversale 32. La substance visqueuse 10 permet d'absorber les, l'énergie due aux chocs, notamment afin d'éviter que les lames ou tiges transversales 320 ne se brisent ou se fissurent. La substance visqueuse 10 peut aussi servir de protection pour les autres parties de la suspension flexible.According to the invention, the flexible suspension 300 comprises a viscous substance 10 which can be placed on one or more parts of the flexible suspension 300. As shown in the picture 2 and 3 , the viscous substance 10 is preferably arranged between the transverse blades or flexible rods 320 of the transverse translation table 32. The viscous substance 10 makes it possible to absorb the energy due to shocks, in particular in order to prevent the blades or cross rods 320 do not break or crack. The viscous substance 10 can also serve as protection for the other parts of the flexible suspension.

La substance visqueuse 10 est aussi agencée entre les lames ou tiges flexibles 310 de la table de translation longitudinale 31.The viscous substance 10 is also arranged between the blades or flexible rods 310 of the longitudinal translation table 31.

De préférence, la substance visqueuse 10 remplit au moins en partie l'espace entre les lames ou tiges flexibles. Ainsi, elle forme un continuum de matière reliant les lames ou tiges flexibles entre elles dans l'espace qui les séparent latéralement.Preferably, the viscous substance 10 at least partially fills the space between the blades or flexible rods. Thus, it forms a continuum of material connecting the blades or flexible rods together in the space which separates them laterally.

Dans une variante de réalisation, la substance visqueuse 10 est agencée au moins en partie autour de la première masse intermédiaire 303. La substance visqueuse est de préférence agencée également au moins en partie autour de la deuxième masse intermédiaire 305. La substance visqueuse 10 est par exemple agencée au moins en partie autour dudit bloc d'ancrage 30.In an alternative embodiment, the viscous substance 10 is arranged at least partly around the first intermediate mass 303. The viscous substance is preferably also arranged at least partly around the second intermediate mass 305. The viscous substance 10 is by example arranged at least in part around said anchor block 30.

Dans une autre variante de réalisation, la substance visqueuse est agencée entre les lames ou tiges flexibles transversales 320 de la table de translation transversale 32, entre les lames ou tiges flexibles 310 de la table de translation longitudinale 31, au moins en partie autour de la première masse intermédiaire 303 au moins en partie autour de la deuxième masse intermédiaire 305, et au moins en partie autour dudit bloc d'ancrage 30.In another variant embodiment, the viscous substance is arranged between the blades or flexible transverse rods 320 of the transverse translation table 32, between the blades or flexible rods 310 of the longitudinal translation table 31, at least partly around the first intermediate mass 303 at least partly around the second intermediate mass 305, and at least partly around said anchor block 30.

Dans un premier mode de réalisation du mécanisme résonateur, la substance visqueuse 10 comprend de la silicone, de préférence sensiblement en totalité. La silicone permet d'absorber l'énergie du choc avec une bonne efficacité.In a first embodiment of the resonator mechanism, the viscous substance 10 comprises silicone, preferably substantially entirely. The silicone absorbs the energy of the impact with good efficiency.

Selon un deuxième mode de réalisation du mécanisme résonateur, la substance visqueuse 10 comprend de la colle sensible au rayonnement ultra-violet. Sous forme visqueuse au départ, une telle colle durcit sous l'effet du rayonnement ultra-violet. Pour son utilisation selon l'invention, on garde la colle sous forme visqueuse, sans appliquer de rayonnement ultra-violet.According to a second embodiment of the resonator mechanism, the viscous substance 10 comprises glue sensitive to ultraviolet radiation. Initially viscous, such an adhesive hardens under the effect of ultraviolet radiation. For its use according to the invention, the adhesive is kept in viscous form, without applying ultraviolet radiation.

Le troisième mode de réalisation de la substance visqueuse 10 comprend du caoutchouc.The third embodiment of the viscous substance 10 comprises rubber.

D'autre matériaux pour la substance visqueuses 10 sont bien-sûr possibles dans d'autres modes de réalisation non décrits ci-dessus.Other materials for the viscous substance 10 are of course possible in other embodiments not described above.

On entend par substance visqueuse, un matériau suffisamment solide pour éviter de s'écouler, mais qui est peut se déformer facilement. Ainsi, la substance visqueuse adhère aux parois de la suspension flexible 300, et reste en place. Lorsque la suspension flexible 300 est en mouvement, la substance visqueuse se déforme et offre une résistance qui dissipe l'énergie, en particulier lorsque le mouvement est important, notamment en cas de choc.By viscous substance is meant a material strong enough to avoid flowing, but which is easily deformed. Thus, the viscous substance adheres to the walls of the flexible suspension 300, and remains in place. When the flexible suspension 300 is in motion, the viscous substance deforms and offers a resistance which dissipates the energy, in particular when the movement is significant, in particular in the event of an impact.

De façon particulière, le mécanisme résonateur 100 comporte des moyens de butée axiale comportant au moins une première butée axiale 7 et une deuxième butée axiale 8 pour limiter la course en translation de l'élément inertiel 2 au moins selon la première direction Z, les moyens de butée axiale étant agencés pour coopérer en appui de butée avec l'élément inertiel 2 pour la protection des lames longitudinales 3 au moins contre les chocs axiaux selon la première direction Z, et le deuxième plan de symétrie est sensiblement à égale distance de la première butée axiale 7 et de la deuxième butée axiale 8.In particular, the resonator mechanism 100 comprises axial stop means comprising at least a first axial stop 7 and a second axial stop 8 to limit the travel in translation of the inertial element 2 at least along the first direction Z, the means axial abutment being arranged to cooperate in abutment support with the inertial element 2 for the protection of the longitudinal blades 3 at least against axial shocks in the first direction Z, and the second plane of symmetry is substantially at equal distance from the first axial stop 7 and the second axial stop 8.

Dans une variante particulière, le mécanisme résonateur 100 comporte une plaque 301, comportant au moins une lame flexible 302 s'étendant dans un plan perpendiculaire à l'axe de pivotement D, et fixée à la structure 1 et à la première masse intermédiaire 303, et qui est agencée pour autoriser une mobilité de la première masse intermédiaire 303 selon la première direction Z. Plus particulièrement, la plaque 301 comporte au moins deux lames flexibles 302 coplanaires. Une telle plaque 301 est toutefois facultative si la hauteur des lames des tables de translation XY est faible par rapport à la hauteur des lames flexibles 3, en particulier inférieure au tiers de la hauteur des lames flexibles 3.In a particular variant, the resonator mechanism 100 comprises a plate 301, comprising at least one flexible blade 302 extending in a plane perpendicular to the pivot axis D, and fixed to the structure 1 and to the first intermediate mass 303, and which is arranged to allow mobility of the first intermediate mass 303 in the first direction Z. More particularly, the plate 301 comprises at least two flexible blades 302 coplanar. Such a plate 301 is however optional if the height of the blades of the XY translation tables is low compared to the height of the flexible blades 3, in particular less than a third of the height of the flexible blades 3.

Dans une variante particulière, la suspension flexible 300 est monobloc, de préférence en silicium.In a particular variant, the flexible suspension 300 is in one piece, preferably in silicon.

Dans une réalisation avantageuse, le mécanisme résonateur 100 comporte un ensemble monobloc, qui regroupe au moins le bloc d'ancrage 30, une embase de l'au moins un élément inertiel 2, le pivot flexible 200, la suspension flexible 300, la première masse intermédiaire 303, et la table de translation transversale 32, et comporte au moins un élément sécable 319 agencé pour solidariser les composants de l'ensemble monobloc pendant leur assemblage sur la structure 1, et dont la rupture libère l'ensemble des composants mobiles de l'ensemble monobloc.In an advantageous embodiment, the resonator mechanism 100 comprises a one-piece assembly, which includes at least the anchor block 30, a base of the at least one inertial element 2, the flexible pivot 200, the flexible suspension 300, the first mass intermediate 303, and the transverse translation table 32, and comprises at least one breakable element 319 arranged to secure the components of the one-piece assembly during their assembly on the structure 1, and the breakage of which frees all the mobile components of the one-piece assembly.

Plus particulièrement, l'ensemble monobloc comporte encore au moins la deuxième masse intermédiaire 305 et la table de translation longitudinale 31.More particularly, the one-piece assembly still includes at least the second intermediate mass 305 and the longitudinal translation table 31.

Comme exposé ci-dessus, la technologie utilisée pour la fabrication permet d'obtenir deux lames distinctes dans la hauteur d'un wafer silicium, ce qui favorise la souplesse en torsion de la table sans l'assouplir pour la translation. Et le mécanisme résonateur 100 peut ainsi avantageusement comporter au moins deux ensembles monoblocs élémentaires superposés, qui regroupent chacun un niveau du bloc d'ancrage 30, et/ou d'une embase de l'au moins un élément inertiel 2, et/ou du pivot flexible 200, et/ou de la suspension flexible 300, et/ou de la première masse intermédiaire 303, et/ou de la table de translation transversale 32, et/ou d'un élément sécable 319 ; chaque ensemble monobloc élémentaire peut être assemblé à au moins un autre ensemble monobloc élémentaire par collage ou similaire, par assemblage mécanique, ou par croissance de SiO2 dans le cas d'une exécution en silicium, ou similaire.As explained above, the technology used for manufacturing makes it possible to obtain two distinct blades in the height of a silicon wafer, which promotes the torsion flexibility of the table without softening it for translation. And the resonator mechanism 100 can thus advantageously comprise at least two superimposed elementary one-piece assemblies, each of which includes a level of the anchoring block 30, and/or of a base of the at least one inertial element 2, and/or of the flexible pivot 200, and/or of the flexible suspension 300, and/or of the first intermediate mass 303, and/or of the transverse translation table 32, and/or of a breakable element 319; each elementary one-piece assembly can be assembled with at least one other elementary one-piece assembly by bonding or similar, by mechanical assembly, or by growth of SiO 2 in the case of an execution in silicon, or similar.

Plus particulièrement, un tel ensemble monobloc élémentaire comporte encore au moins un niveau de la deuxième masse intermédiaire 305 et/ou de la table de translation longitudinale 31.More particularly, such an elementary one-piece assembly further comprises at least one level of the second intermediate mass 305 and/or of the longitudinal translation table 31.
