Description

Technical Field

[0001] The invention relates to a timepiece resonator mechanism comprising a structure and an anchoring mass to which at least one inertial element is suspended, a virtual pivot comprising a plurality of substantially longitudinal elastic strips, each elastic strip being fixed at a first end to said anchoring mass and at a second end to said inertial element.

[0002] The invention also relates to a timepiece movement comprising at least one such resonator mechanism.

[0003] The present invention relates to the field of timepiece resonators and more particularly to those comprising an elastic strip acting as reset means for the operation of the oscillator. Background Art

[0004] For most watch oscillators that include at least one spiral hairspring or an elastic strip constituting a flexible guide, and in particular for cross-stripe resonators, the torsional rigidity of the suspension system is a difficulty. And the shock resistance also depends on this torsional rigidity; in fact, during a shock, the stresses borne by the strips quickly reach very high values, which further reduces the travel that the component can travel before failure. Shock absorbers for timepieces are of many variants. However, their main purpose is to protect the fragile pivot of the resonator axis, rather than to protect the elastic element, such as the spiral hairspring in general.

[0005] According to application CH15442016 and its derivative patents in the name of ETA Manufacture Horlogère Suisse, the teachings of which are directly applicable to the present invention and whose resonator's sensitivity to shocks in some specific directions can be further improved, a new mechanism architecture allows maximizing the quality factor of the resonator by using a flexible guide of an anchor escapement with a very small lift angle. The problem is therefore to protect the strap from breaking in the event of shocks. It is obvious that the anti-shock systems proposed so far for resonators with flexible guides only protect the strap from shocks in certain directions, but not in all directions, or such anti-shock systems have the drawback of allowing the embedding of the virtual pivot to move slightly according to its oscillating rotation, which should be avoided as much as possible.

[0006] Application CH5182018 or application EP18168765 in the name of ETA Manufacture Horlogère Suisse describes a timepiece resonator mechanism comprising a structure carrying an anchoring block by a flexible suspension system, to which an inertial element is suspended, the inertial element oscillating according to a first rotational freedom RZ under the action of a restoring force exerted by a virtual pivot, the virtual pivot comprising first elastic strips, each of which is fixed to the inertial element and to the anchoring block, the flexible suspension system being arranged so as to allow a certain mobility of the anchoring block according to all degrees of freedom except the first rotational freedom RZ, only the inertial element being movable according to the first rotational freedom RZ in order to avoid any interference with its oscillation, and the stiffness of the suspension system according to the first rotational freedom RZ being very much higher than the stiffness of the virtual pivot according to this same first rotational freedom RZ.

[0007] Application CH715526 or application EP3561607 in the name of ETA Manufacture Horlogère Suisse describe a timepiece resonator mechanism comprising a structure and an anchoring block to which is suspended at least one inertial element, arranged to oscillate according to a first rotational degree of freedom RZ about a pivot axis extending in a first direction Z, said inertial element being subject to a restoring force exerted by a virtual pivot comprising a plurality of substantially longitudinal elastic strips, each of which is fixed at a first end to said anchoring block and at a second end to said inertial element, each of said elastic strips being deformable substantially in a plane XY perpendicular to said first direction Z.

[0008] However, sometimes one or more of the strips of the flexible suspension system breaks during a strong shock, or wears out prematurely until it can break after a series of small shocks. In fact, the flexible suspension system avoids the breaking of the virtual pivot, but the flexible suspension system is subjected to shocks instead. Summary of the invention

[0009] The present invention proposes to improve the resonator mechanism of application CH715526 or application EP3561607 in the name of ETA Manufacture Horlogère Suisse so as to protect the flexible suspension system from the above-mentioned drawbacks.

[0010] To this end, the invention relates to a timepiece resonator mechanism comprising a structure and an anchoring block to which is suspended at least one inertial element, arranged to oscillate according to a first rotational degree of freedom RZ about a pivot axis extending in a first direction Z, said inertial element being subject to a restoring force exerted by a virtual pivot comprising a plurality of substantially longitudinal elastic strips, each of which is fixed at a first end to said anchoring block and at a second end to said inertial element, each of said elastic strips being substantially deformable in a plane XY perpendicular to said first direction Z, said anchoring block being suspended to said structure by a flexible suspension system arranged to allow mobility of said anchoring block.

[0011] The present invention is unique in that the resonator mechanism includes a viscous substance disposed at least partially around the flexible suspension system, the viscous substance being configured to at least partially dissipate energy generated by the oscillations.

[0012] Due to the sticky substance, the flexible suspension system is better protected in the event of strong shocks, in particular against premature breakage or splitting of the flexible suspension system, in particular one of the strips or rods. Thus, a double protection is obtained: a first protection of the strips of the virtual pivot thanks to the flexible suspension system, and a second protection of the flexible suspension system by the sticky substance. Thus, the invention improves the protection of the resonator mechanism against the risk of breakage.

[0013] According to a specific embodiment of the invention, the flexible suspension system comprises a lateral translation platform with a flexible guide between the anchor block and the first intermediate mass member, the first intermediate mass member being fixed to the structure directly or by means of a flexible plate in the first direction Z, and the lateral translation platform comprising at least two lateral flexible strips or rods, which are preferably linear and extend in the second direction X and are symmetrical about a lateral axis intersecting the pivot axis.

[0014] According to a particular embodiment of the invention, the viscous substance is arranged between transverse flexible strips or rods of the transverse translation platform.

[0015] According to a particular embodiment of the invention, the viscous substance is at least partially arranged around the first intermediate mass.

[0016] According to a particular embodiment of the invention, the adhesive substance is arranged at least partially around said anchoring block.

[0017] According to a particular embodiment of the invention, the viscous substance is arranged at least partially around the second intermediate mass.

[0018] According to a particular embodiment of the invention, the adhesive substance comprises a glue that is sensitive to ultraviolet radiation.

[0019] According to a particular embodiment of the invention, the viscous substance comprises rubber.

[0020] According to a particular embodiment of the invention, the adhesive substance comprises silicone.

[0021] According to a specific embodiment of the present invention, the flexible suspension system includes a longitudinal translation platform with a flexible guide between the anchor block and the second intermediate mass member, and the longitudinal translation platform includes at least two longitudinal flexible strips or rods, which are preferably straight and extend in the third direction Y and are symmetrical about a longitudinal axis intersecting the pivot axis; and the flexible suspension system includes the lateral translation platform between the second intermediate mass member and the first intermediate mass member.

[0022] According to a particular embodiment of the invention, the viscous substance is at least partially arranged between the longitudinal flexible strips or rods of the longitudinal translation platform.

[0023] According to a particular embodiment of the invention, the viscous substance is arranged at least partially around the second intermediate mass.

[0024] According to a particular embodiment of the invention, the flexible suspension system is made in one piece.

[0025] According to a particular embodiment of the invention, the flexible suspension system is made of silicon.

[0026] According to a specific embodiment of the present invention, the anchor block is movable according to five flexible degrees of freedom of the suspension system, and the five flexible degrees of freedom are: a first translational degree of freedom along the first direction Z, a second translational degree of freedom along a second direction X orthogonal to the first direction Z, a third translational degree of freedom along a third direction Y orthogonal to the second direction X and the first direction Z, a second rotational degree of freedom RX around an axis extending in the second direction X, and a third rotational degree of freedom RY around an axis extending in the third direction YX.

[0027] The invention also relates to a timepiece movement comprising at least one resonator mechanism according to the invention and / or at least one timepiece oscillator mechanism comprising a timepiece resonator mechanism and an escapement arranged to cooperate with each other.

[0033] The present invention relates to a timepiece resonator mechanism constituting a variant of the resonator described in application CH5182018 or in application EP18168765 in the name of ETA Manufacture Horlogère Suisse, which are incorporated herein by reference and which a person skilled in the art will be able to combine with the features of the present invention. Figures 1 to 4 , the timepiece resonator mechanism 100 comprises a structure 1 and an anchoring block 30 to which is suspended at least one inertial element 2 arranged to oscillate according to a first rotational freedom RZ about a pivot axis D extending in a first direction Z. The inertial element 2 comprises a balance wheel 20. The balance wheel has the shape of a bone, comprising a straight section with a bulb at each end thereof. Each bulb may comprise a small inertial mass 29 to adjust the inertia of the inertial element 2. The inertial element 2 is subjected to a restoring force exerted by a virtual pivot 200 comprising a plurality of substantially longitudinal elastic strips 3, each of which is fixed at a first end to the anchoring block 30 and at a second end to the inertial element 2. Each elastic strip 3 is substantially deformable in a plane XY perpendicular to the first direction Z.

[0034] The anchor block 30 is suspended to the structure 1 by a flexible suspension system 300 arranged to allow mobility of the anchor block 30 according to five flexible degrees of freedom of the suspension system, which are:

[0035] - a first translational degree of freedom along a first direction Z;

[0036] - a second degree of freedom of translation along a second direction X orthogonal to the first direction Z;

[0037] - a third degree of freedom of translation along a third direction Y orthogonal to the second direction X and to the first direction Z;

[0038] - a second rotational degree of freedom RX about an axis extending in a second direction X; and

[0039] - a third rotational degree of freedom RY about an axis extending in a third direction Y.

[0040] The principle is to use the torsional flexibility of the translation platform to better manage the torsional stiffness of the suspension system. For this purpose, the strips of the platform XY are oriented so that the direction of greater torsional flexibility is aligned with the axis of rotation of the resonator. Its torsional flexibility is managed by bringing the strips together.

[0041] Therefore, the flexible suspension system 300 includes a lateral translation platform 32 with flexible guides between the anchor block 30 and the first intermediate mass member 303, which is fixed to the structure 1 directly or by means of a flexible plate 301 in the first direction Z, and the lateral translation platform 32 includes a lateral strip 320 or a lateral flexible rod, which is straight and extends in the second direction X.

[0042] In a specific non-limiting embodiment, and as shown by the figures, the flexible suspension system 300 also includes a longitudinal translation platform 31 with flexible guides between the anchor block 30 and the second intermediate mass 305, and the longitudinal translation platform 31 includes a longitudinal strip 310 or a longitudinal flexible rod that is linear and extends in the third direction Y. And, between the second intermediate mass 305 and the first intermediate mass 303, the lateral translation platform 32 with flexible guides includes a lateral strip 320 or a lateral flexible rod that is linear and extends in the second direction X.

[0043] More particularly, the longitudinal axis D1 intersects the transverse axis D2, and in particular, the longitudinal axis D1, the transverse axis D2 and the pivot axis D are co-pointing.

[0044] More particularly, the longitudinal translation platform 31 and the transverse translation platform 32 each include at least two flexible strips or rods, each strip or rod being characterized by its thickness in the second direction X when the strip or rod extends in the third direction Y, or vice versa; each strip or rod is characterized by its height in the first direction Z, and by its length in the direction in which the strip or rod extends, the length being, for example, at least five times as large as the height, the height being at least as large as the thickness, and more particularly at least five times as large as the thickness, and even more particularly at least seven times as large as the thickness.

[0045] More specifically, the lateral translation platform 32 includes at least two lateral flexible strips or rods that are parallel to each other and have the same length. Figures 1 to 4 A non-limiting variant is shown with four parallel transverse strips, and more particularly each transverse strip is composed of two half-strips arranged on two superposed layers and extending continuously to one another in a first direction Z. These half-strips can either be completely free relative to one another, or they can be fastened together by gluing or the like, or by growth of SiO2 in the case of the silicon embodiment, or the like. Of course, the longitudinal translation platform 31 (when it is present, since it is optional) can follow the same construction principle. The number, arrangement and cross-section of these strips or rods can vary without departing from the invention.

[0046] The principle is to use the torsional flexibility of the translation platform to better manage the torsional stiffness of the suspension system. For this purpose, the strips of the platform XY are oriented so that the direction of greater torsional flexibility is aligned with the axis of rotation of the resonator. Its torsional flexibility is managed by bringing the strips together.

[0047] Therefore, the flexible suspension system 300 includes a lateral translation platform 32 with flexible guides between the anchor block 30 and the first intermediate mass member 303, which is fixed to the structure 1 directly or by means of a flexible plate 301 in the first direction Z, and the lateral translation platform 32 includes a lateral strip 320 or a lateral flexible rod, which is straight and extends in the second direction X.

[0048] In a specific non-limiting embodiment, and as shown by the figures, the flexible suspension system 300 also includes a longitudinal translation platform 31 with flexible guides between the anchor block 30 and the second intermediate mass 305, and the longitudinal translation platform 31 includes a longitudinal strip 310 or a longitudinal flexible rod that is linear and extends in the third direction Y. And, between the second intermediate mass 305 and the first intermediate mass 303, the lateral translation platform 32 with flexible guides includes a lateral strip 320 or a lateral flexible rod that is linear and extends in the second direction X.

[0049] More particularly, the longitudinal axis D1 intersects the transverse axis D2, and in particular, the longitudinal axis D1, the transverse axis D2 and the pivot axis D are co-pointing.

[0050] More particularly, the longitudinal translation platform 31 and the transverse translation platform 32 each include at least two flexible strips or rods, each strip or rod being characterized by its thickness in the second direction X when the strip or rod extends in the third direction Y, or vice versa; each strip or rod is characterized by its height in the first direction Z, and by its length in the direction in which the strip or rod extends, the length being, for example, at least five times as large as the height, the height being at least as large as the thickness, and more particularly at least five times as large as the thickness, and even more particularly at least seven times as large as the thickness.

[0051] More specifically, the lateral translation platform 32 includes at least two lateral flexible strips or rods that are parallel to each other and have the same length. Figures 1 to 4 A non-limiting variant is shown with four parallel transverse strips and more particularly each transverse strip is composed of two half-strips arranged on two superimposed layers and extending continuously to one another in a first direction Z. These half-strips may either be completely free relative to one another or may be fastened together by gluing or the like, or by growth of SiO2 in the case of the silicon embodiment, or the like. Of course, the longitudinal translation platform 31 (when it is present, since it is optional) may follow the same construction principle. The number, arrangement and cross-section of these strips or rods may vary without departing from the invention. More particularly, the transverse strips or rods of the transverse translation platform 32 have a first plane of symmetry which is parallel to the transverse axis D2 and which passes through the pivot axis D.

[0052] More specifically, the transverse strip or rod of the transverse translation platform 32 has a second plane of symmetry parallel to the transverse axis D2 and orthogonal to the pivot axis D.

[0053] More specifically, the transverse strip or rod of the transverse translation platform 32 has a third plane of symmetry perpendicular to the transverse axis D2 and parallel to the pivot axis D.

[0054] More specifically, the transverse strips or bars of the transverse translation platform 32 extend in at least two mutually parallel layers, each perpendicular to the pivot axis D.

[0055] More particularly, the arrangement of the transverse strips or rods of the transverse translation platform 32 is identical on each level.

[0056] More particularly, the transverse strips or linear flexible rods 320, 1320 are flat strips whose height is at least five times greater than their thickness.

[0057] More particularly, 1 to 11, the transverse strips or straight flexible rods 320 are rods of square or circular cross-section, the height of which is equal to the thickness.

[0058] More specifically, the longitudinal translation platform 31 comprises at least two longitudinal flexible strips or rods parallel to each other and having the same length.

[0059] More specifically, the longitudinal strip or rod of the longitudinal translation platform 31 has a first plane of symmetry parallel to the longitudinal axis D1 and passing through the pivot axis D.

[0060] More specifically, the longitudinal strip or rod of the longitudinal translation platform 31 has a second plane of symmetry parallel to the longitudinal axis D1 and orthogonal to the pivot axis D.

[0061] More specifically, the longitudinal strips or rods of the longitudinal translation platform 31 have a third plane of symmetry perpendicular to the longitudinal axis D1 and parallel to the pivot axis D.

[0062] More particularly, the transverse strips or rods of the longitudinal translation platform 31 extend in at least two mutually parallel layers, each perpendicular to the pivot axis D.

[0063] More specifically, the arrangement of the transverse strips or bars of the longitudinal translation platform 31 is identical on each level.

[0064] More particularly, the longitudinal strips or linear flexible rods 310 are flat strips whose height is at least five times greater than their thickness.

[0065] In a variant not shown in the drawings, the longitudinal strips or rectilinear flexible rods 310 are rods of square or circular section, the height of which is equal to the thickness.

[0066] According to the present invention, the flexible suspension system 300 includes a viscous substance 10, which may be disposed on one or more portions of the flexible suspension system 300. Figure 2 and Figure 3 , the adhesive substance 10 is preferably arranged between the transverse flexible strips or rods 320 of the transverse translation platform 32. The adhesive substance 10 allows absorbing the energy generated by the shocks, in particular to prevent the transverse strips or rods 320 from breaking or cracking. The adhesive substance 10 can also serve as a protection for other parts of the flexible suspension system.

[0067] The viscous substance 10 is also disposed between the flexible strips or rods 310 of the longitudinal translation platform 31 .

[0068] Preferably, the adhesive substance 10 at least partially fills the space between the flexible strips or rods. Thus, it forms a continuum of material that connects the flexible strips or rods to each other in the space that separates them laterally.

[0069] In an alternative embodiment, the adhesive substance 10 is arranged at least partially around the first intermediate mass 303. The adhesive substance is preferably also arranged at least partially around the second intermediate mass 305. For example, the adhesive substance 10 is arranged at least partially around the anchor block 30.

[0070] In another variant embodiment, the viscous substance is arranged between the lateral flexible strips or rods 320 of the lateral translation platform 32, between the flexible strips or rods 310 of the longitudinal translation platform 31, at least partially around the first intermediate mass piece 303, at least partially around the second intermediate mass piece 305, and at least partially around the anchor block 30.

[0071] In a first embodiment of the resonator mechanism, the adhesive substance 10 comprises silicone, preferably substantially in its entirety. Silicone absorbs the energy of the oscillations with good efficiency.

[0072] According to a second embodiment of the resonator mechanism, the adhesive substance 10 comprises a glue that is sensitive to ultraviolet radiation. When initially tacky, such an adhesive hardens under the action of ultraviolet radiation. For its use according to the invention, the glue is kept in a tacky form without applying ultraviolet radiation.

[0073] A third embodiment of the adhesive substance 10 includes rubber.

[0074] In other embodiments not described above, other materials for the adhesive mass 10 are of course possible.

[0075] Viscous substances refer to materials that are strong enough to avoid flow but which deform easily. Therefore, the viscous substance adheres to the walls of the flexible suspension system 300 and remains in its position. When the flexible suspension system 300 moves, especially when the movement is large, especially in the case of shock, the viscous substance deforms and provides resistance, which dissipates energy.

[0076] In particular, the resonator mechanism 100 comprises an axial stop device, which comprises at least a first axial stop 7 and a second axial stop 8 to limit the translational travel of the inertial element 2 at least in the first direction Z; the axial stop device is arranged to cooperate with the inertial element 2 to protect the longitudinal strip 3 at least from axial oscillations in the first direction Z, and the second symmetry plane is located at a substantially equal distance from the first axial stop 7 and the second axial stop 8.

[0077] In a particular variant, the resonator mechanism 100 comprises a plate 301 comprising at least one flexible strip 302 extending in a plane perpendicular to the pivot axis D and fixed to the structure 1 and to a first intermediate mass 303 and arranged to allow mobility of the first intermediate mass 303 in a first direction Z. More particularly, the plate 301 comprises at least two coplanar flexible strips 302. However, such a plate 301 is optional if the height of the strips of the translation platform XY is low compared to the height of the flexible strips 3, in particular less than one third of the height of the flexible strips 3.

[0078] In a particular variant, the flexible suspension system 300 is made in one piece, preferably in silicon.

[0079] In an advantageous embodiment, the resonator mechanism 100 comprises a one-piece assembly comprising at least an anchor block 30, a base of at least one inertial element 2, a flexible pivot 200, a flexible suspension system 300, a first intermediate mass 303, and a lateral translation platform 32, and comprises at least one breakable element 319 arranged to secure the components of the one-piece assembly during assembly of the components on the structure 1, and the rupture of the breakable element 319 will release all movable components from the one-piece assembly.

[0080] More specifically, the one-piece assembly further includes at least a second intermediate mass 305 and a longitudinal translation platform 31 .

[0081] As discussed above, the manufacturing technology used allows obtaining two different strips in the height of the silicon wafer, which increases the torsional flexibility of the platform without making it more flexible for translation. And the resonator mechanism 100 can therefore advantageously include at least two superimposed basic one-piece components, each of which includes an anchor block 30, and / or a base of at least one inertial element 2, and / or a flexible pivot 200, and / or a flexible suspension system 300, and / or a first intermediate mass 303, and / or a lateral translation platform 32, and / or a layer of a breakable element 319; each basic one-piece component can be assembled with at least one other basic one-piece component by bonding, etc., by mechanical assembly, or in the case of a silicon embodiment by growth of SiO2, etc.

[0082] More particularly, such a basic one-piece assembly also comprises a second intermediate mass 305 and / or at least one layer of the longitudinal translation platform 31 .

[0083] The present invention also relates to a timepiece oscillator mechanism comprising such a timepiece resonator mechanism 100 and an escapement mechanism, the timepiece resonator mechanism 100 and the escapement mechanism being arranged to cooperate with each other.

[0084] The invention also relates to a timepiece movement comprising at least one such oscillator mechanism and / or at least one resonator mechanism 100 .
