Description

Field of the invention

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, to a first end to said anchor block, and at a second end to said inertial element.

The invention also relates to a clock movement comprising at least one such resonator mechanism.

The invention relates to the field of clockwork resonators, and more particularly those which comprise elastic blades acting as return means for the operation of the oscillator.

Background of the invention

[0004] The torsional 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.

[0005] New architectures of mechanisms make it possible to maximize the quality factor of a resonator, by the use of flexible guidance with the use of a lever escapement with a very small angle of lift, according to demand. CH15442016 in the name of ETA Manufacture Horlogère Suisse and its derivatives, the teachings of which can be directly used 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 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.

[0006] Application CH5182018 or application EP18168765 in the name of ETA Manufacture Horlogère Suisse describes a clockwork resonator 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 restoring 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 block anchorage 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 movable 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 stiffness 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 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 rotational freedom RZ about 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 strips, each fixed, to a first end of said anchor block, and at a second end of 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 it is one or more blades of the flexible suspension, which break during a major impact, 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. In particular, when the mechanism undergoes a shock in the Z direction, which is perpendicular to the flexible suspension, the latter undergoes a rotation around an axis of the plane of the suspension, which can cause one or more blades to break. .

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 aforementioned drawbacks.

[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 block of anchoring, 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 block anchor according to a plurality of degrees of freedom including at least two in the XY plane, along an X direction and along an orthogonal Y direction in said direction X, said flexible suspension comprising, between said anchor 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 transverse blades or transverse flexible rods, rectilinear and extending along said second direction X.

The invention is remarkable in that the mechanism comprises stop means arranged to limit the travel in rotation and/or in translation of the flexible suspension in at least one direction.

[0012] Thus, by the stop means, the flexible suspension is stopped in the event of a major shock, in particular in the Z direction, to prevent one of its blades or rods from breaking. 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 thanks to the stop means. Consequently, the invention improves the protection of the resonator mechanism against the risk of breakage.

Detailed Description of Preferred Embodiments

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, incorporated here by reference, and of which the person skilled in the art will know combine the characteristics with those specific to the present invention. Shown in FIGS. 1 to 3, 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 around a pivot axis D 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.

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.

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.

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 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.

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, straight 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 along the second direction X.

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.

More specifically, 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.

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. Figures 1 to 5 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 according to the first direction Z. These half-blades can either be entirely free with respect to each other, or else secured by gluing or the like, or by growth of SiO2 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.

According to the invention, the resonator mechanism 100 comprises abutment means 10 arranged to limit the travel in rotation and/or in translation of the flexible suspension 300 in at least one direction. Preferably, the stop means limit the travel of the flexible suspension 300 in the Z direction. Thus, in the event of an impact on the resonator mechanism in the Z direction, the flexible suspension 300 performs a rotation along RX or RY, but is blocked by the abutment means, so that the blades of the suspension are preserved. To this end, the abutment means bear above and/or below the flexible suspension to retain the suspension in the Z direction.

[0044] In addition, the abutment means limit the rotational and translational travel of the flexible suspension in one direction of the XY plane. Thus, in the event of an impact on the resonator mechanism in the XY plane, the flexible suspension 300 performs a rotation along RZ, but is blocked by the stop means. To this end, the abutment means bear laterally against the flexible suspension to retain the suspension in the XY plane. The stroke is limited to a predefined value, for example 100 μm with respect to the rest position of said flexible suspension 300 in direction Z. To this end, said stop means 10 are arranged at a distance corresponding to the predefined value.

In a first embodiment, shown in Figure 2, said abutment means 10 are arranged close to the second intermediate mass 305, so that said abutment means 10 are arranged to cooperate in abutment support with said second intermediate mass 305. Said abutment means 10 are arranged at least partially cantilevered above said second intermediate mass 305 to reduce its stroke in the Z direction. Thus, protection is obtained for said blades or rods transverse 320, or longitudinal 310 at least against shocks along the Z axis around the axes of rotation RX or RY. In the event of impact, the flexible suspension 300 moves in the Z direction around the axes of rotation RX or RY.

In addition, said stop means 10 being arranged close to the second intermediate mass 305, they reduce its travel in the XY plane. Thus, additional protection is obtained for said blades or transverse 320 or longitudinal 310 rods at least against radial shocks in the XY plane around the axis of rotation RZ. In the event of an impact, the flexible suspension 300 moves in the XY plane to absorb the shocks. If the shock is too great, the stroke of the flexible suspension 300 is reduced because the second intermediate mass 305 is stopped by the stop means 10.

In Figures 2 and 3, said stop means 10 comprise a stud extending perpendicular to the plane of the flexible suspension. In FIG. 6, the stud comprises a first cylindrical section 11 embedded in a static element of the movement, such as a bridge or a plate, by snap-fastening means 14, then a second cylindrical section 12 that is narrower above the first section 11 and a screw head 13 on the second section 12. The screw head 13 has a greater width than the second section 12. The screw head 13 is cantilevered above the second intermediate mass 305 to reduce its travel in the Z direction. Thus, said abutment means 10 comprise at least two stages to control the movement of the intermediate parts in the Z direction.

[0048]Other forms of stops are obviously possible, such as non-stepped studs, cubic studs, screws, or part of a static element of the movement. In a second embodiment, shown in Figure 3, said abutment means 10 are arranged through an opening 15 of the flexible suspension 300. The opening 15 has dimensions corresponding to the predefined value to obtain the desired travel, the radius being for example substantially equivalent to the predefined value in the case of a circular opening. Thus, the edge of the opening 15 touches the abutment means 10, in the event of a violent impact in the XY plane, while the abutment means act in the same way as the first embodiment in the event of an impact in the direction Z. The stop means are assembled to a static element of the movement under the flexible suspension 300.

According to different variants of each embodiment, the abutment means can be provided only in the XY plane or in the Z direction. In other words, the embodiments described mention several directions, but they can be provided only for the direction Z or in the XY plane for example, by choosing adequate dimensions. In a variant of each embodiment, said abutment means 10 comprise a shock-absorbing material, such as polymers, for example of the polyoxymethylene type.

According to another variant of each embodiment, said abutment means 10 comprise a rigid material, such as metal.

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 axial abutment means being arranged to cooperate in abutment bearing 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 of the first axial stop 7 and of the second axial stop 8.

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 mass intermediate 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.

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 virtual 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 one-piece assembly during their assembly on the structure 1, and the breaking of which frees all the components mobiles of the one-piece assembly.

[0054] More particularly, the one-piece assembly still comprises at least the second intermediate mass 305 and the longitudinal translation table 31.

As explained above, the technology used for manufacturing makes it possible to obtain two separate 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 virtual 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 SiO2 in the case of a silicon execution, or similar.

[0056] 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.

The invention also relates to a clock movement comprising at least one such resonator mechanism 100.

The invention also relates to a watch comprising at least one such movement and/or at least one such resonator mechanism 100.
