Viscous element-equipped shock-absorbing protection for a resonator mechanism with flexible rotary guide

Description

Field of invention

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

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

[0003] The invention relates to the field of clock resonators, and in particular those which comprise elastic blades acting as return means for the operation of the oscillator. Background of the invention

[0004] The torsional rigidity of the suspension is a delicate point for most watch oscillators with at least one spiral spring or elastic blades constituting a flexible guide, and in particular for crossed blade resonators. And shock resistance also depends on this torsional rigidity; in fact, during impacts, the stress undergone by the blades quickly reaches very high values, which reduces the travel that the part can travel before giving way. Shock absorbers for watch parts are available in many variants. However, their main purpose is to protect the fragile pivots of the resonator axis, and not the elastic elements, such as the classical spiral spring.

[0005] New mechanism architectures make it possible to maximize the quality factor of a resonator, by using flexible guidance with the use of an anchor escapement with a very small lifting angle, according to application CH15442016 in the name of ETA Manufacture Horlogère Suisse and its derivatives, the teachings of which are directly usable in the present invention, and the resonator of which can be further improved with regard to its sensitivity to shocks, in certain particular directions. It is therefore a question of protecting the blades from breaking in the event of shocks. We realize that the anti-shock systems proposed to date for resonators with flexible guidance, protect the blades from shocks in certain directions only, but not in all directions, or that they have the defect of allowing the embedding of the virtual pivot to move slightly according to its oscillation rotation, which is to be avoided as much as possible.

[0006] Application CH5182018 or application EP18168765 in the name of ETA Manufacture Horlogère Suisse describes a watch resonator mechanism, comprising a structure supporting, by a flexible suspension, an anchor 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 anchor block, the flexible suspension being arranged to allow a certain mobility of the anchor block according to all the degrees of freedom other than 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 much greater than the rigidity of the virtual pivot according to this same first degree of freedom in rotation RZ.

[0007] Application CH715526 or application EP3561607 in the name of ETA Manufacture Horlogère Suisse describes a watch resonator mechanism, comprising a structure and an anchoring block from which is suspended at least one inertial element arranged to oscillate according to a first degree of freedom in rotation RZ around a pivot axis extending in a first direction Z, said inertial element being subjected to return forces exerted by a virtual pivot comprising a plurality of substantially longitudinal elastic blades, each fixed, at a first end to said anchoring block, and at a second end to said inertial element, each said elastic blade being deformable essentially in an XY plane perpendicular to said first direction Z.

[0008] However, it happens that one or more blades of the flexible suspension break during a major impact, or that they wear prematurely until a probable rupture following a series of small impacts. In fact, the flexible suspension avoids the breakage of the virtual pivot, but it takes the shock in its place. Summary of the invention

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

[0010] 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 in a first direction Z, said inertial element being subjected to return forces exerted by a virtual pivot comprising a plurality of substantially longitudinal elastic blades, each fixed, at a first end to said anchoring block, and at a second end to said inertial element, each said elastic blade being deformable essentially in an XY plane perpendicular to said first direction Z, said anchoring block being suspended from said structure by a flexible suspension arranged to allow the mobility of said anchoring block.

[0011] The invention is remarkable in that the resonator mechanism comprises a viscous substance arranged at least in part around the flexible suspension, the viscous substance being configured to dissipate at least in part the energy due to a shock, the viscous substance being a deformable material sufficiently strong to avoid flowing, and which adheres to the walls of the flexible suspension.

[0012] Thanks to the viscous substance, the flexible suspension is better protected in the event of a significant impact, in particular to prevent the flexible suspension, in particular one of the blades or rods, from breaking or cracking prematurely. Thus, there is 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.

[0013] According to a particular embodiment of the invention, said flexible suspension comprises, between said anchoring block and a first intermediate mass, which is fixed to said structure directly or by means of a flexible plate in said first direction Z, a transverse translation table with flexible guidance and comprising at least two transverse flexible blades or rods, preferably rectilinear, and extending in said second direction X and in symmetry around a transverse axis crossing said pivot axis.

[0016] According to a particular embodiment of the invention, the viscous substance is arranged at least in part around said anchoring block. According to a particular embodiment of the invention, the viscous substance is arranged at least in part around the second intermediate mass.

[0018] According to a particular embodiment of the invention, the viscous substance comprises rubber.

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

[0020] According to a particular embodiment of the invention, said flexible suspension comprises, between said anchoring block and a second intermediate mass, a longitudinal translation table with flexible guidance and comprising at least two longitudinal flexible blades or rods, preferably rectilinear, and extending in said third direction Y and in symmetry around a longitudinal axis crossing said pivot axis, and comprises said transverse translation table between said second intermediate mass and said first intermediate mass.

[0021] According to a particular embodiment of the invention, the viscous substance is arranged at least partly between the longitudinal flexible blades or rods of the longitudinal translation table.

[0022] According to a particular embodiment of the invention, the viscous substance is arranged at least partly around the second intermediate mass.

[0023] According to a particular embodiment of the invention, the flexible suspension is in one piece.

[0024] According to a particular embodiment of the invention, the flexible suspension is made of silicon.

[0025] According to a particular embodiment of the invention, the anchoring block is movable according to five flexible degrees of freedom of the suspension which are a first degree of freedom in translation according to said first direction Z, a second degree of freedom in translation according to a second direction X orthogonal to said first direction Z, a third degree of freedom in translation according to a third direction Y orthogonal to said second direction X and to said first direction Z, a second degree of freedom in rotation RX around an axis extending according to said second direction X, and a third degree of freedom in rotation RY around an axis extending according to said third direction YX

[0026] 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 mechanism, which are arranged to cooperate with each other.

Detailed Description of Preferred Embodiments

[0028] The invention relates to a clockwork resonator mechanism, which constitutes a variant of the resonators described in application CH5182018 or application EP18168765 in the name of ETA Manufacture Horlogère Suisse, the characteristics of which will be known to those skilled in the art to combine with those specific to the present invention. Represented in the figures 1 to 4, this resonator mechanism 100 of clockwork comprises a structure 1 and an anchoring block 30, from which is suspended at least one inertial element 2 arranged to oscillate according to a first degree of freedom in rotation RZ around a pivot axis D extending in a first direction Z. The inertial element 2 comprises a balance 20. The balance has a bone shape, the balance comprising a straight segment provided with a bulb at each end. Each bulb may comprise small weights 29 to adjust the inertia of the inertial element 2. This inertial element 2 is subjected to return forces exerted by a virtual pivot 200 comprising a plurality of substantially longitudinal elastic blades 3, each fixed, at a first end to the anchoring block 30, and at a second end to the inertial element 2. Each elastic blade 3 is deformable essentially in an XY plane perpendicular to the first direction Z.

[0029] 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.

[0030] The principle is to use the torsional flexibility of a translation table to better manage the torsional rigidities of the suspension. To do this, the blades of the XY tables are oriented so that the direction of greatest torsional flexibility is aimed at the axis of rotation of the resonator. Their torsional flexibility is managed by bringing the blades closer together.

[0031] Thus, the flexible suspension 300 comprises, between the anchoring block 30 and a first intermediate mass 303, which is fixed to the structure 1 directly or by means of a flexible plate 301 in the first direction Z, a transverse translation table 32 with flexible guidance, and which comprises transverse blades 320 or transverse flexible rods, rectilinear and extending in the second direction X.

[0032] In a particular non-limiting embodiment, and as illustrated by the figures, the flexible suspension 300 also comprises, between the anchoring block 30 and a second intermediate mass 305, a longitudinal translation table 31 with flexible guidance, and which comprises longitudinal blades 310 or longitudinal flexible rods, rectilinear and extending in the third direction Y. And, between the second intermediate mass 305 and the first intermediate mass 303, the transverse translation table 32 with flexible guidance comprises transverse blades 320 or transverse flexible rods, rectilinear and extending in the second direction X.

[0033] 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 concurrent.

[0034] More particularly, the longitudinal translation table 31 and the transverse translation table 32 each comprise at least two flexible blades or 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.

[0035] More particularly, the transverse translation table 32 comprises at least two transverse flexible blades or rods, parallel to each other and of the same length. figures 1 to 4illustrate a non-limiting variant with four parallel transverse blades, and, more particularly, each consisting of two half-blades arranged on two superimposed levels, and extending in the extension of one another in the first direction Z. These half-blades can be, either entirely free relative to one another, or secured by gluing or the like, or by growth of SiO 2 in the case of a silicon execution, or the like. Naturally, the longitudinal translation table 31, when it exists since it is optional, can obey the same construction principle. The number, arrangement, and section of these blades or rods can vary without departing from the present invention.

[0036] The principle is to use the torsional flexibility of a translation table to better manage the torsional rigidities of the suspension. To do this, the blades of the XY tables are oriented so that the direction of greatest torsional flexibility is aimed at the axis of rotation of the resonator. Their torsional flexibility is managed by bringing the blades closer together.

[0037] Thus, the flexible suspension 300 comprises, between the anchoring block 30 and a first intermediate mass 303, which is fixed to the structure 1 directly or by means of a flexible plate 301 in the first direction Z, a transverse translation table 32 with flexible guidance, and which comprises transverse blades 320 or transverse flexible rods, rectilinear and extending in the second direction X.

[0038] In a particular non-limiting embodiment, and as illustrated by the figures, the flexible suspension 300 also comprises, between the anchoring block 30 and a second intermediate mass 305, a longitudinal translation table 31 with flexible guidance, and which comprises longitudinal blades 310 or longitudinal flexible rods, rectilinear and extending in the third direction Y. And, between the second intermediate mass 305 and the first intermediate mass 303, the transverse translation table 32 with flexible guidance comprises transverse blades 320 or transverse flexible rods, rectilinear and extending in the second direction X.

[0039] 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 concurrent.

[0040] More particularly, the longitudinal translation table 31 and the transverse translation table 32 each comprise at least two flexible blades or 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.

[0041] More particularly, the transverse translation table 32 comprises at least two transverse flexible blades or rods, parallel to each other and of the same length. figures 1 to 4illustrate a non-limiting variant with four parallel transverse blades, and, more particularly, each consisting of two half-blades arranged on two superimposed levels, and extending in the extension of one another in the first direction Z. These half-blades can be, either entirely free relative to one another, or secured by gluing or the like, or by growth of SiO 2 in the case of a silicon execution, or the like. Naturally, the longitudinal translation table 31, when it exists since it is optional, can obey the same construction principle. The number, arrangement, and section of these blades or rods, can vary without departing from the present invention. 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.

[0042] 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.

[0043] More particularly, the transverse blades or 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.

[0044] More particularly, the transverse blades or 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.

[0045] More particularly, the arrangement of the transverse blades or rods of the transverse translation table 32 is identical on each of the levels.

[0046] 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.

[0047] More particularly, 1 to 11, the transverse blades or rectilinear flexible rods 320 are rods of square or circular section whose height is equal to the thickness.

[0048] More particularly, the longitudinal translation table 31 comprises at least two longitudinal flexible blades or rods, parallel to each other and of the same length.

[0049] More particularly, the longitudinal blades or rods of the longitudinal translation table 31 have a first plane of symmetry, which is parallel to the longitudinal axis D1, and which passes through the pivot axis D.

[0050] More particularly, the longitudinal blades or 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.

[0051] More particularly, the longitudinal blades or 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.

[0052] More particularly, the transverse blades or rods of the longitudinal translation table 31 extend over at least two levels parallel to each other, each level being perpendicular to the pivot axis D.

[0053] More particularly, the arrangement of the transverse blades or rods of the longitudinal translation table 31 is identical on each of the levels.

[0054] More particularly, the longitudinal blades or rectilinear flexible rods 310 are flat blades whose height is at least five times greater than their thickness.

[0055] In a variant, not shown in the figures, the longitudinal blades or rectilinear flexible rods 310 are rods of square or circular section whose height is equal to the thickness.

[0056] According to the invention, the flexible suspension 300 comprises a viscous substance 10 which can be arranged on one or more parts of the flexible suspension 300. As shown in figure 2 And 3, the viscous substance 10 is preferably arranged between the transverse flexible blades or rods 320 of the transverse translation table 32. The viscous substance 10 makes it possible to absorb the energy due to impacts, in particular in order to prevent the transverse blades or rods 320 from breaking or cracking. The viscous substance 10 can also serve as protection for the other parts of the flexible suspension.

[0057] The viscous substance 10 is also arranged between the flexible blades or rods 310 of the longitudinal translation table 31.

[0058] Preferably, the viscous substance 10 at least partially fills the space between the flexible blades or rods. Thus, it forms a continuum of material connecting the flexible blades or rods to each other in the space which separates them laterally.

[0059] In an alternative embodiment, the viscous substance 10 is arranged at least in part around the first intermediate mass 303. The viscous substance is preferably also arranged at least in part around the second intermediate mass 305. The viscous substance 10 is for example arranged at least in part around said anchoring block 30.

[0060] In another embodiment, the viscous substance is arranged between the transverse flexible blades or rods 320 of the transverse translation table 32, between the flexible blades or 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 anchoring block 30.

[0061] In a first embodiment of the resonator mechanism, the viscous substance 10 comprises silicone, preferably substantially entirely. The silicone makes it possible to absorb the energy of the impact with good efficiency.

[0062] According to a second embodiment of the resonator mechanism, the viscous substance 10 comprises glue sensitive to ultraviolet radiation. Initially in viscous form, such glue hardens under the effect of ultraviolet radiation. For its use according to the invention, the glue is kept in viscous form, without applying ultraviolet radiation.

[0063] The third embodiment of the viscous substance 10 comprises rubber.

[0064] Other materials for the viscous substance 10 are of course possible in other embodiments not described above.

[0065] The viscous substance is a material that is strong enough to avoid flowing, but can deform easily. 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 provides resistance that dissipates energy, particularly when the motion is significant, such as in the event of an impact.

[0066] 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 translational travel of the inertial element 2 at least in the first direction Z, the axial stop means being arranged to cooperate in abutment with the inertial element 2 for the protection of the longitudinal blades 3 at least against axial impacts in the first direction Z, and the second plane of symmetry is substantially equidistant from the first axial stop 7 and the second axial stop 8.

[0067] 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 coplanar flexible blades 302. 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.

[0068] In a particular variant, the flexible suspension 300 is monobloc, preferably made of silicon.

[0069] In an advantageous embodiment, the resonator mechanism 100 comprises a single-piece assembly, which groups together at least the anchoring block 30, a base of the at least one inertial element 2, the flexible pivot 200, the flexible suspension 300, the first intermediate mass 303, and the transverse translation table 32, and comprises at least one breakable element 319 arranged to secure the components of the single-piece assembly during their assembly on the structure 1, and the rupture of which releases all of the mobile components of the single-piece assembly.

[0070] More particularly, the single-piece assembly also comprises at least the second intermediate mass 305 and the longitudinal translation table 31.

[0071] 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 torsional flexibility of the table without making it more flexible for translation. And the resonator mechanism 100 can thus advantageously comprise at least two superimposed elementary monobloc assemblies, each of which groups together a level of the anchoring block 30, and / or a base of the at least one inertial element 2, and / or the flexible pivot 200, and / or the flexible suspension 300, and / or the first intermediate mass 303, and / or the transverse translation table 32, and / or a breakable element 319; each elementary monobloc assembly can be assembled to at least one other elementary monobloc assembly by gluing or the like, by mechanical assembly, or by SiO 2 growth in the case of a silicon execution, or the like.

[0072] More particularly, such an elementary single-block assembly also comprises at least one level of the second intermediate mass 305 and / or of the longitudinal translation table 31.

[0073] The invention also relates to a clockwork oscillator mechanism comprising such a clockwork resonator mechanism 100, and an escapement mechanism, arranged to cooperate with each other.

[0074] The invention also relates to a clockwork movement comprising at least one such oscillator mechanism and / or at least one resonator mechanism 100.
