Organe régulateur pour montre bracelet et procédé d'assemblage d'un organe régulateur pour montre bracelet  Regulator organ for a wristwatch and method for assembling a regulating organ for a wristwatch

[0001] La présente invention concerne un organe régulateur pour montre-bracelet, notamment un organe régulateur électronique pour montre-bracelet mécanique. The present invention relates to a regulator member for a wristwatch, in particular an electronic regulator member for a mechanical wristwatch.
Etat de la technique State of the art
[0002] Les montres-bracelets mécaniques sont habituellement régulées au moyen d'un assortiment comportant un spiral et un balancier. La précision qui peut être obtenue à l'aide d'un organe régulateur de ce type est cependant limitée. [0003] Les montres électroniques sont habituellement régulées au moyen d'un oscillateur à quartz.

périodiquement. [0004] Afin de palier à ces inconvénients, on connaît également dans l'état de la technique des montres comprenant un mouvement mécanique régulé par un circuit électronique avec un oscillateur à quartz. L'énergie nécessaire au circuit électronique est fournie par un générateur entraîné par le mouvement. [0005] Ainsi, CH-A-597636 (Ebauches S.A.) propose un mouvement mécanique avec un ressort de barillet et un générateur. Le ressort actionne, par l'intermédiaire d'un rouage, un indicateur horaire et le générateur qui délivre une tension alternative. Le générateur alimente un redresseur qui charge une capacité de stockage afin d'alimenter un oscillateur à quartz ainsi qu'un circuit électronique de réglage. Le circuit électronique de réglage comporte un circuit logique de comparaison et un circuit de dissipation d'énergie relié à la sortie du circuit logique de comparaison, dont l'absorption de puissance peut être commandée par le circuit logique de comparaison. Une entrée du circuit logique de comparaison est reliée avec le circuit de référence et une autre entrée du circuit logique de comparaison est reliée avec le générateur. Le circuit logique de periodically. In order to overcome these disadvantages, it is also known in the state of the art of watches comprising a mechanical movement controlled by an electronic circuit with a quartz oscillator. The energy required for the electronic circuit is provided by a motion-driven generator. Thus, CH-A-597636 (Ebauches SA) proposes a mechanical movement with a mainspring and a generator. The spring actuates, by means of a gear train, a time indicator and the generator that delivers an alternating voltage. The generator supplies a rectifier that charges a storage capacity to power a crystal oscillator and an electronic control circuit. The electronic control circuit comprises a comparison logic circuit and a control circuit. energy dissipation connected to the output of the comparison logic circuit, the power absorption of which can be controlled by the comparison logic circuit. An input of the comparison logic circuit is connected to the reference circuit and another input of the comparison logic circuit is connected to the generator. The logical circuit of

In such a watch, the advantages of a mechanical watch, that is to say the absence of batteries, are combined with the precision of a quartz watch.
[0007] EP905589 décrit un circuit de freinage pour microgénérateur horloger, comportant un compteur et un circuit de freinage qui freine dès que la valeur accumulée dans le compteur dépasse un seuil. [0007] EP905589 describes a braking circuit for a watchmaking microgenerator, comprising a counter and a braking circuit which brakes as soon as the value accumulated in the counter exceeds a threshold.
[0008] EP816955, dont le contenu est incorporé par référence, décrit une amélioration aux circuits électroniques de contrôle de générateurs horlogers, dans laquelle le redresseur de tension comporte des transistors commandés par des comparateurs pour remplacer les diodes après le démarrage du circuit. [0008] EP816955, the content of which is incorporated by reference, describes an improvement to the electronic control circuits of watchmakers, in which the voltage rectifier comprises transistors controlled by comparators to replace the diodes after the start of the circuit.
[0009] WO0063749, dont le contenu est incorporé par référence, décrit un mouvement de montre avec un microgénérateur. Afin d'éviter l'accumulation de charges électriques, les roues et les pignons du rouage sont reliés électriquement à la terre (c'est-à-dire à la platine) et réalisés dans un matériau non magnétique. [0009] WO0063749, the content of which is incorporated by reference, describes a watch movement with a microgenerator. In order to avoid the accumulation of electric charges, the wheels and pinions of the gear train are electrically connected to the ground (that is to say to the plate) and made of a non-magnetic material.
[0010] EP0851322 décrit un générateur pour mouvement de montre comportant un stator avec trois bobines connectées électriquement et un rotor muni de régions magnétisées. Les bobines sont disposées de manière asymétrique autour de l'axe du rotor, afin de permettre de glisser le rotor entre les bobines lors du montage. Cette disposition asymétrique entraîne cependant une légère perte de l'efficacité du générateur. EP0851322 discloses a watch movement generator comprising a stator with three coils electrically connected and a rotor provided with magnetized regions. The coils are asymmetrically arranged around the axis of the rotor to allow the rotor to slide between the coils during assembly. This asymmetrical arrangement, however, causes a slight loss of the efficiency of the generator.
[0011] Les organes régulateurs ci-dessus permettent ainsi de remplacer les organes balanciers-spiraux qui équipent la majorité des montres mécaniques, en offrant une précision plus élevée. Idéalement, on The above regulators and allow to replace the balance-spiral bodies that equip the majority of mechanical watches, offering higher accuracy. Ideally, we
souhaiterait pouvoir modifier un mouvement mécanique existant en remplaçant l'organe réglant conventionnel par un de ces organes réglants nouveaux. Cependant, bien que les dimensions du générateur soient en général compatibles avec celles des balanciers existants, il n'est pas possible de placer facilement le circuit imprimé qui porte les bobines et would like to be able to modify an existing mechanical movement by replacing the conventional regulating organ with one of these new regulating organs. However, although the dimensions of the generator are generally compatible with those of the existing balances, it is not possible to easily place the printed circuit which carries the coils and

Therefore, it is generally necessary to completely change the design of the mechanical movement to place the regulating member.
[0012] D'autre part, le montage de cet organe réglant est généralement délicat. Le rotor doit être assemblé en même temps que le reste du rouage avec lequel il engrène ; ensuite, les bobines du stator doivent être montées en regard du rotor. EP0851322 apporte certes une simplification au montage, en permettant de glisser un circuit imprimé portant les bobines statoriques et l'électronique de régulation autour de l'axe du rotor déjà monté. Cette simplification se fait cependant au prix d'une perte On the other hand, the mounting of this regulating organ is generally difficult. The rotor must be assembled at the same time as the rest of the gear with which it meshes; then, the stator coils must be mounted facing the rotor. EP0851322 certainly provides a simplification to the assembly, allowing to slide a printed circuit carrying the stator coils and the control electronics around the axis of the rotor already mounted. This simplification is however at the cost of a loss
d'efficacité énergétique. D'autre part, le montage du circuit imprimé autour du rotor, dans un mouvement presque complètement assemblé, est particulièrement délicat. Il est en outre nécessaire de prévoir un espace suffisant à proximité des bobines statoriques pour la portion du circuit imprimé dédiée au quartz et aux autres éléments de l'électronique de régulation ; cette place est souvent indisponible à proximité du rotor. energy efficiency. On the other hand, the assembly of the printed circuit around the rotor, in a movement almost completely assembled, is particularly delicate. It is also necessary to provide sufficient space near the stator coils for the portion of the printed circuit dedicated to quartz and the other elements of the control electronics; this place is often unavailable near the rotor.
[0013] Différentes solutions existent dans l'état de la technique pour placer le circuit imprimé qui porte l'électronique à distance des bobines du stator. Ainsi, JP2012122933 décrit une montre comprenant un générateur avec un stator et un rotor. Le stator comporte des bobines et un corps de stator à distance du circuit imprimé. De la même façon, JP2001042066 concerne une montre comportant un générateur avec des bobines séparées du reste de l'électronique. Ces documents ne décrivent cependant pas la manière dont les différentes bobines du stator sont alignées et conectées électriquement entre elles. Various solutions exist in the state of the art for placing the printed circuit which carries the electronics away from the stator coils. Thus, JP2012122933 discloses a watch comprising a generator with a stator and a rotor. The stator has coils and a stator body remote from the printed circuit. In the same way, JP2001042066 relates to a watch comprising a generator with separate coils from the rest of the electronics. These documents, however, do not describe the manner in which the different coils of the stator are aligned and electrically connected to each other.
[0014] EP1048989 décrit une montre à microgénératrice avec un circuit électronique monté sur un substrat rigide qui porte aussi une des deux bobines du stator. Un deuxième substrat rigide porte deux autres bobines du stator. L'électronique se trouve donc nécessairement à proximité d'au moins une des bobines, ce qui est contraignant. D'autre part, les différentes bobines du stator sont montées sur des substrats différents qui doivent être assemblés séparément et parfaitement alignés entre eux de manière à garantir un couplage magnétique suffisant avec le rotor. [0014] EP1048989 describes a microgenerator watch with an electronic circuit mounted on a rigid substrate which also carries one of the two stator coils. A second rigid substrate carries two other stator coils. The electronics is therefore necessarily close to at least one of the coils, which is binding. On the other hand, the different coils of the stator are mounted on different substrates which must be assembled separately and perfectly aligned with each other so as to ensure sufficient magnetic coupling with the rotor.
Bref résumé de l'invention Brief summary of the invention
[0015] Un but de la présente invention est donc de proposer un organe régulateur électronique pour montre-bracelet exempt de ces limitations. An object of the present invention is therefore to provide an electronic controller for wristwatch free of these limitations.
[0016] Selon l'invention, ces buts sont atteints notamment au moyen d'un organe régulateur pour montre bracelet, comportant : According to the invention, these objects are achieved in particular by means of a regulating member for a wristwatch, comprising:

un deuxième circuit imprimé pour porter et connecter électroniquement toutes les dites bobines du générateur ;  a second printed circuit for electronically carrying and connecting all said coils of the generator;
le premier circuit et le deuxième circuit constituant deux modules distincts séparés géographiquement l'un de l'autre et connectés électriquement l'un à l'autre.  the first circuit and the second circuit constituting two distinct modules separated geographically from one another and electrically connected to each other.
[0017] Cette solution permet de séparer le circuit reliant les bobines du générateur du circuit électronique ; les deux circuits sont connectés électriquement l'un à l'autre au moyen de pistes conductrices. [0018] Les bobines sont toutes montées sur le même circuit imprimé, ce qui évide de devoir contrôler leur alignement lors du montage, tout en facilitant leur interconnexion. This solution makes it possible to separate the circuit connecting the coils of the generator of the electronic circuit; both circuits are electrically connected to one another by means of conductive tracks. The coils are all mounted on the same printed circuit, which avoids having to check their alignment during assembly, while facilitating their interconnection.
[0019] L'électronique est montée sur un autre circuit imprimé, qui peut donc être placé loin des bobines à n'importe quel endroit dans la montre. The electronics is mounted on another printed circuit, which can be placed far from the coils at any point in the watch.
[0020] Ainsi, il est possible de réaliser le circuit électronique de [0020] Thus, it is possible to produce the electronic circuit of

Au moins un des plateaux rotoriques peut être dans un état démonté lorsque le rotor est assemblé, puis monté après coup sur l'axe. De cette manière, il n'est pas nécessaire de prévoir un espace entre les bobines adjacentes supérieur au diamètre de l'axe du rotor; les bobines peuvent même être contiguës. connection can be removable.

In one embodiment, the rotor comprises two rotor plates on either side of the stator and connected by the axis of the rotor which passes between the coils. At least one of the rotor platens may be in a disassembled condition when the rotor is assembled, and then mounted laterally on the shaft.

électroniquement par le biais d'un deuxième circuit 1 1 . Ce deuxième circuit 1 1 est de préférence aussi un circuit imprimé, par exemple un circuit imprimé flexible, comportant des pistes conductrices 1 10 pour connecter les bobines entre elles et à un troisième circuit imprimé 6 décrit plus bas. electronically through a second circuit 1 1. This second circuit 1 1 is preferably also a printed circuit, for example a flexible printed circuit, comprising conductive tracks 1 to connect the coils together and to a third printed circuit 6 described below.
Alternativement, les bobines 10 peuvent être liées électroniquement de manière modulaire mais sans avoir besoin d'une plaque d'un circuit imprimé. Alternatively, the coils 10 may be electronically bonded in a modular manner but without the need for a plate of a printed circuit.
[0033] Les bobines 10 sont de préférence régulièrement espacées angulairement autour de l'axe 20.

Le circuit imprimé 1 1 est chassé ou collé dans le châssis 3. D'autres modes de fixation mécaniques sont également possibles (par exemple par clipsage). A chassis 3 made of injected synthetic material makes it possible to fix the printed circuit 1 1 on the plate or on a bridge of the watch movement, by means of screws passing in the earpieces 30. The printed circuit 1 1 is driven out or glued in. the frame 3. Other mechanical fastening modes are also possible (for example by clipping).
[0035] Le rotor 2 comporte un premier plateau rotorique 22a et un deuxième plateau rotorique 22b. Les deux plateaux rotoriques sont destinés à tourner de part et d'autre du stator. Ils sont reliés entre eux et mis en rotation par un axe de rotor 20 qui passe dans l'interstice entre les bobines 10 et qui est entraîné au moyen d'un pignon non illustré par le rouage du mouvement dont il règle la marche. The rotor 2 comprises a first rotor plate 22a and a second rotor plate 22b. The two rotor plates are intended to rotate on either side of the stator. They are interconnected and rotated by a rotor axis 20 which passes into the gap between the coils 10 and which is driven by means of a pinion not shown by the work train of which it adjusts the running.

permanents 21 a, respectivement 21 b générant un champ magnétique tournant qui induit un courant alternatif dans les bobines 10 lorsque le rotor tourne. Les aimants permanents 21 a, 21 b peuvent être constitués par des aimants discrets ou par un anneau magnétisé. Dans une variante, les plateaux rotoriques 22a, 22b sont magnétisés et constituent donc permanent 21a, respectively 21b generating a rotating magnetic field that induces an alternating current in the coils 10 when the rotor rotates. Permanent magnets 21a, 21b may be constituted by discrete magnets or a magnetized ring. In a variant, the rotor plates 22a, 22b are magnetized and therefore constitute
directement les aimants permanents. directly permanent magnets.
[0037] Au moins un des deux plateaux rotoriques 22a et/ou 22b est démontable pour permettre l'insertion de l'axe de rotor 20 dans l'interstice au centre de toutes les bobines 10 du stator. Dans l'exemple de la figure 1 , le plateau rotorique inférieur 22b est démontable. Il est aussi possible de prévoir un plateau rotorique supérieur 22a démontable, ou les deux plateaux rotoriques démontables. [0038] Le plateau rotorique inférieur 22b comporte une ouverture 220b qui permet d'insérer l'axe de rotor 20. Le plateau rotorique 22b est maintenu le long de l'axe 20 entre une portée de cet axe et une bague 23b qui peut être chassée ou clipsée sur cet axe. Dans des variantes, le plateau rotorique 22b peut être chassé sur l'axe du rotor 20 sans avoir besoin de recourir à la bague 23b. At least one of the two rotor plates 22a and / or 22b is removable to allow insertion of the rotor axis 20 in the gap in the center of all the coils 10 of the stator. In the example of Figure 1, the lower rotor plate 22b is removable. It is also possible to provide a removable upper rotor plate 22a, or the two removable rotor plates. The lower rotor plate 22b has an opening 220b which allows to insert the rotor axis 20. The rotor plate 22b is held along the axis 20 between a bearing of this axis and a ring 23b which can be chased or clipped on this axis. In variants, the rotor plate 22b can be driven on the axis of the rotor 20 without the need to use the ring 23b.
[0039] La surface du circuit imprimé du deuxième circuit 1 1 portant les bobines 10 du stator 1 , ainsi que les dimensions du châssis 3, sont de préférence sensiblement de la même dimension que le rotor 2. En The surface of the printed circuit of the second circuit 1 1 carrying the coils 10 of the stator 1, as well as the dimensions of the frame 3, are preferably substantially of the same dimension as the rotor 2. In FIG.
particulier, le circuit 1 1 ne comporte de préférence aucun autre composant électronique hormis les bobines 10. Ainsi, il est possible de placer ce générateur à la place de l'organe balancier-spiral de nombre de in particular, the circuit 1 1 preferably comprises no other electronic component except the coils 10. Thus, it is possible to place this generator in place of the balance spring-balance member of
mouvements mécaniques existants. existing mechanical movements.
[0040] La vitesse de rotation du rotor est régulée par le premier circuit électronique 8 qui est de préférence également monté sur un circuit imprimé 80 tel qu'illustré sur la figure 3. Il est alimenté électriquement par les courants induits dans les bobines 10 par le champ magnétiques tournant généré par la rotation des aimants permanents 21 a, 21 b. Le circuit électronique 8 peut être par exemple conforme au circuit décrit dans EP816955 et comporte un circuit électronique asic 82 pour comparer la fréquence du signal induit dans les bobines 10 avec une fréquence délivrée par un oscillateur à quartz 81 . Les éléments 83 sont des capacités utilisées pour la multiplication et le redressage de tension. The rotational speed of the rotor is regulated by the first electronic circuit 8 which is preferably also mounted on a printed circuit 80 as illustrated in FIG. 3. It is electrically powered by the currents induced in the coils 10 by the rotating magnetic field generated by the rotation of the permanent magnets 21 a, 21 b. The electronic circuit 8 may for example be in accordance with the circuit described in EP816955 and comprises an asic electronic circuit 82 for comparing the frequency of the signal induced in the coils 10 with a frequency delivered by a quartz oscillator 81. The elements 83 are capacitors used for multiplication and voltage straightening.
[0041] Le premier circuit 8 est relié électriquement au deuxième circuit 1 1 portant le stator par des pistes électriquement conductrices 60. Dans l'exemple illustré, ces pistes sont constituées sur un troisième circuit 6 en forme d'un circuit imprimé flexible 60. Ce troisième circuit imprimé 60 peut être indépendant, ou constituer une portion du circuit imprimé du deuxième circuit 1 1 , comme illustré. Il est aussi imaginable de prévoir un troisième circuit imprimé 60 constituant une portion du premier circuit imprimé 80. Selon des variantes, les pistes conductrices 60 peuvent être remplacées par toutes autres formes de liaison électrique appropriées. The first circuit 8 is electrically connected to the second circuit 1 1 carrying the stator by electrically conductive tracks 60. In the illustrated example, these tracks are constituted on a third circuit 6 in the form of a flexible printed circuit 60. This third printed circuit 60 may be independent, or constitute a portion of the printed circuit of the second circuit January 1, as illustrated. It is also conceivable to provide a third printed circuit 60 constituting a portion of the first printed circuit 80. According to variants, the conductive tracks 60 may be replaced by any other suitable electrical connection forms.
[0042] Dans l'exemple illustré, la connexion électrique entre le troisième circuit imprimé flexible 60 et le premier circuit imprimé 80 est non permanente et assurée par un connecteur amovible, par exemple au moins une vis 61 électriquement conductrice, mais un autre type de connecteur amovible (par exemple à étrier, ou par clipsage) peut également être utilisé. Chacun des deux circuits 8 et 1 1 peut aussi comporter un plan de masse tous deux connectés à la platine 50 ou à un pont du mouvement 5, pour assurer une connexion électrique via cette masse entre ces circuits. La figure 4 illustre de manière simplifiée un mouvement assemblé selon l'invention. Seuls certains composants sont illustrés notamment l'organe réglant 2, 6, 8 et le barillet 7. D'autres composants, notamment le rouage, etc., ne sont pas illustrés pour simplifier la figure. In the illustrated example, the electrical connection between the third flexible printed circuit 60 and the first printed circuit 80 is non-permanent and provided by a removable connector, for example at least one electrically conductive screw 61, but another type of detachable connector (eg caliper, or clipping) can also be used. Each of the two circuits 8 and 11 may also comprise a ground plane both connected to the plate 50 or to a bridge of the movement 5, to ensure an electrical connection via this mass between these circuits. Figure 4 schematically illustrates an assembled movement according to the invention. Only certain components are illustrated including the regulating member 2, 6, 8 and the barrel 7. Other components, including the wheel, etc., are not illustrated to simplify the figure.
[0044] Avec l'organe régulateur de la présente invention le générateur M est modulaire et peut être assemblé en dehors du mouvement de montre 5. Par la suite, le châssis 3 est fixé à la platine ou à un pont, par exemple au moyen de vis dans les oreillettes 30, etle deuxième circuit 1 1 est ensuite lié au troisième circuit 6 par le connecteur amovible. With the regulator of the present invention the generator M is modular and can be assembled outside the watch movement 5. Subsequently, the frame 3 is fixed to the plate or a bridge, for example by means of screws in the atria 30, and the second circuit 1 1 is then connected to the third circuit 6 by the removable connector.
[0045] Une partie de rotor 2a avec un plateau rotorique 22a, les aimants 21 a et l'axe 20 est ensuite glissé dans l'interstice au centre des bobines 10 du stator ; le deuxième plateau rotorique 21 b, 22b est ensuite glissé sur l'axe 20 de l'autre côté du stator 1 , puis maintenu grâce à la bague 23b chassée ou tenue sur l'axe 20. Dans une variante, la bague peut être supprimée et le plateau rotorique peut être chassé directement sur l'axe. [0046] Alternativement, il est possible de monter une partir du rotor, par exemple les éléments 21 a, 22a et l'axe 20, avant le montage du stator enfilé autour de cet axe. Le deuxième plateau rotorique est ensuite fixé de l'autre côté du stator. A rotor portion 2a with a rotor plate 22a, the magnets 21a and the axis 20 is then slid into the gap in the center of the coils 10 of the stator; the second rotor plate 21b, 22b is then slid on the axis 20 on the other side of the stator 1, then maintained by the ring 23b driven or held on the axis 20. In a variant, the ring can be removed and the rotor plate can be driven directly on the 'axis. Alternatively, it is possible to mount a part of the rotor, for example the elements 21a, 22a and the axis 20, before mounting the stator threaded around this axis. The second rotor plate is then fixed on the other side of the stator.
Le premier circuit imprimé 80 est ensuite fixé sur la platine ou sur un pont du mouvement 5, puis relié électriquement au troisième circuit imprimé 6 au moyen d'un connecteur, par exemple d'au moins une vis assurant une connexion électrique entre au moins une piste 60 du troisième circuit imprimé et une piste du premier circuit imprimé 80. Il est aussi possible de placer ce premier circuit imprimé et de le connecter électriquement avant le montage du rotor. Il est aussi possible de placer ce premier circuit imprimé avant le montage du deuxième circuit imprimé. The first printed circuit 80 is then fixed on the plate or on a bridge of the movement 5, then electrically connected to the third printed circuit 6 by means of a connector, for example at least one screw providing an electrical connection between at least one track 60 of the third printed circuit and a track of the first printed circuit 80. It is also possible to place this first printed circuit and to connect it electrically before mounting the rotor. It is also possible to place this first printed circuit before mounting the second circuit board.
