Description

Module horloger électromécanique comportant une antenne  Electromechanical watch module with an antenna
Domaine technique Technical area
[0001] La présente invention concerne un module horloger The present invention relates to a watch module
électromécanique comportant une antenne pour transmettre et/ou recevoir un signal sans-fil. electromechanical device comprising an antenna for transmitting and / or receiving a wireless signal.
Etat de la technique [0002] Des montres ayant une fonction de communication sans fil sont connues. A cette fin, une antenne doit être disposée dans l'espace confiné de la montre. Comme la réception de l'antenne est perturbée au environ d'un matériau électriquement conducteur, l'antenne a été souvent placée à l'extérieur du boîtier. Par exemple, dans les documents DE3508366 et DE8815967, une antenne est incorporée dans le bracelet. Un tel State of the art [0002] Watches having a wireless communication function are known. For this purpose, an antenna must be placed in the confined space of the watch. Since the reception of the antenna is disturbed by about one electrically conductive material, the antenna has often been placed outside the housing. For example, in DE3508366 and DE8815967, an antenna is incorporated in the bracelet. Such
arrangement a le désavantage que l'antenne est vulnérable à la cassure. Autrement, l'antenne est le plus souvent placée autour d'un cadran de la montre, le boîtier métallique de la montre servant de plan de masse. arrangement has the disadvantage that the antenna is vulnerable to breakage. Otherwise, the antenna is most often placed around a dial of the watch, the metal case of the watch serving as a ground plane.
L'antenne peut également être placée sur une lunette de la montre. [0003] Cependant, le placement d'une antenne à l'extérieur a le désavantage de ne pas être compatible avec les critères esthétiques d'une montre. En particulier, l'habillage d'une montre comporte préférablement des pièces métalliques, telles que le boîtier et le cadran, ont une finition de grande précision. Une antenne placée à l'extérieure du boîtier compromet alors l'esthétisme de la montre et doit donc être recouverte afin de ne pas dégrader l'apparence extérieure. The antenna can also be placed on a bezel of the watch. However, the placement of an antenna outside has the disadvantage of not being compatible with the aesthetic criteria of a watch. In particular, the dressing of a watch preferably comprises metal parts, such as the case and the dial, have a high precision finish. An antenna placed outside the housing then compromises the aesthetics of the watch and must be covered so as not to degrade the external appearance.
[0004] Dans des développement plus récents, l'antenne est logée à l'intérieur du boîtier, sous le cadran. Dans un tel arrangement, les connections mécanique et électrique entre le mouvement de la montre et l'antenne sont moins susceptible aux interférences extérieures. [0005] Dans le document DE4441424, une antenne est logée dans un boîtier non-métallique comprenant un cadran également non métallique. Cependant, les boîtiers et cadrans fabriqués dans des matériaux non métalliques ne répondent pas toujours aux critères esthétiques In more recent development, the antenna is housed inside the housing, under the dial. In such an arrangement, the mechanical and electrical connections between the movement of the watch and the antenna are less susceptible to external interference. In the document DE4441424, an antenna is housed in a non-metallic housing comprising a dial also non-metallic. However, cases and dials made of non-metallic materials do not always meet aesthetic criteria
normalement acceptés dans l'horlogerie. De plus, de tels boîtiers et cadrans ne permettent pas d'obtenir les propriétés mécaniques attendues. normally accepted in watchmaking. In addition, such housings and dials do not provide the expected mechanical properties.
[0006] Cependant, dans le cas où les composants de l'habillage sont métalliques, ces derniers vont jouer le rôle d'un blindage However, in the case where the components of the cladding are metallic, these will play the role of a shielding
électromagnétique pour l'antenne et les performance de l'antenne ne seront pas satisfaisantes. Le défi est donc d'assurer la constance de la qualité de réception et émission de l'antenne tout en utilisant les matériaux usuels dans lesquels est fabriqué l'habillage de la montre et le cadran. electromagnetic antenna and antenna performance will not be satisfactory. The challenge is to ensure the consistency of the quality of reception and emission of the antenna while using the usual materials in which is made the dressing of the watch and the dial.
[0007] Dans le document US2006164921 , une antenne annulaire est logée à l'intérieur du boîtier comportant un cadran métallique. L'antenne est disposée à une distance supérieure à 0.5 mm du cadran. Cette distance est suffisante pour permettre une réception adéquate In US2006164921, an annular antenna is housed inside the housing having a metal dial. The antenna is located at a distance greater than 0.5 mm from the dial. This distance is sufficient to allow adequate reception

[0009] Selon l'invention, ces buts sont atteints notamment au moyen d'un module horloger électromécanique comprenant une platine principale comportant un module actuateur entraînant au moins un mobile par l'intermédiaire d'un rouage, le mobile étant destiné à l'affichage d'une fonction horaire ou non-horaire; un module de communication sans fil configuré pour transmettre et/ou recevoir un signal sans-fil; et une unité de contrôle configurée pour contrôler le module actuateur (40) en fonction d'un signal sans-fil reçu; le mobile et le rouage étant fabriqués dans un matériau électriquement conducteur et étant en contact électrique l'un avec l'autre mais électriquement isolés du reste du module horloger; le mobile étant électriquement connecté au module de communication de manière à agir comme antenne pour la transmission et/ou réception du signal sans-fil et de transmettre le signal sans-fil entre le mobile et le module de communication sans fil. limitations of known watch modules.

[0010] Le module horloger électromécanique de l'invention comportant une antenne permet de bonnes performances pour la réception et l'émission de l'antenne dans le cas où le module comporte un cadran électriquement conducteur et est disposé dans un boîtier électriquement conducteur. The electromechanical watch module of the invention comprising an antenna provides good performance for receiving and transmitting the antenna in the case where the module comprises an electrically conductive dial and is disposed in an electrically conductive housing.

[0019] Le module actuateur 40 peut comprendre d'autres configurations et peut être configuré pour mettre en mouvement qu'une seule aiguille ou deux aiguilles, ou encore un ou plusieurs disques ou tout autre type de mobile. Par exemple, le module actuateur 40 peut comprendre un moteur bidirectionnel actionnant une aiguille rétrograde. The actuator module 40 may comprise other configurations and may be configured to set in motion only one needle or two needles, or one or more disks or any other type of mobile. For example, the actuator module 40 may comprise a bidirectional motor operating a retrograde needle.
