Description

Domaine techniqueTechnical area

La présente invention concerne un mécanisme horloger électromécanique comportant une antenne pour transmettre et/ou recevoir un signal sans-fil.The present invention relates to an electromechanical watch mechanism comprising an antenna for transmitting and / or receiving a wireless signal.

Etat de la techniqueState of the art

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 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. L'antenne peut également être placée sur une lunette de la montre.Watches having a wireless communication function are known. To this end, an antenna must be placed in the confined space of the watch. As the reception of the antenna is disturbed to about an electrically conductive material, the antenna has often been placed outside the housing. For example, in documents DE3508366 and DE8815967 , an antenna is incorporated in the bracelet. Such an 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. The antenna can also be placed on a watch bezel.

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, qui 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.However, the placement of an antenna outside has the disadvantage of not being compatible with the aesthetic criteria of a watch. In particular, the casing of a watch preferably comprises metal parts, such as the case and the dial, which have a high precision finish. An antenna placed outside the case then compromises the aesthetics of the watch and must therefore be covered so as not to degrade the external appearance.

Dans des développements plus récents, l'antenne est logée à l'intérieur du boîtier, sous le cadran. Dans un tel arrangement, les connections mécaniques et électriques entre le mouvement de la montre et l'antenne sont moins susceptibles aux interférences extérieures.In more recent developments, the antenna is housed inside the case, under the dial. In such an arrangement, the mechanical and electrical connections between the watch movement and the antenna are less susceptible to outside interference.

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 normalement acceptés dans l'horlogerie. De plus, de tels boîtiers et cadrans ne permettent pas d'obtenir les propriétés mécaniques attendues.In the document DE4441424 , an antenna is housed in a non-metallic casing comprising a dial which is also non-metallic. However, cases and dials made from non-metallic materials do not always meet the aesthetic criteria normally accepted in watchmaking. In addition, such cases and dials do not make it possible to obtain the expected mechanical properties.

Cependant, dans le cas où les composants de l'habillage sont métalliques, ces derniers vont jouer le rôle d'un blindage électromagnétique pour l'antenne et les performances 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.However, in the case where the components of the covering are metallic, the latter will play the role of an electromagnetic shielding for the antenna and the performance of the antenna will not be satisfactory. The challenge is therefore to ensure the consistency of the reception and transmission quality of the antenna while using the usual materials from which the watch casing and the dial are made.

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 adéquateIn the document US2006164921 , an annular antenna is housed inside the housing comprising a metal dial. The antenna is placed at a distance greater than 0.5 mm from the dial. This distance is sufficient to allow adequate reception.

US9141089 décrit une montre comprenant un cadran, un arbre sur lequel sont montées deux aiguilles configurées pour tourner de 360 degrés dans un plan autour de l'arbre, un élément d'antenne couplé à l'arbre et configuré pour tourner de 360 degrés dans le même plan autour de l'arbre et un circuit pour l'élément d'antenne. US9141089 describes a watch comprising a dial, a shaft on which are mounted two hands configured to rotate 360 degrees in a plane around the shaft, an antenna element coupled to the shaft and configured to rotate 360 degrees in the same plan around the tree and a circuit for the antenna element.

US2015/185707 décrit une montre comprenant un cadran ainsi qu'une première aiguille et une seconde aiguille. Lorsque la première aiguille est positionnée à une position prédéterminée sensiblement perpendiculaire à la seconde aiguille, les première et seconde aiguilles sont configurées pour envoyer/recevoir des signaux sans-fil. US2015 / 185707 describes a watch comprising a dial as well as a first hand and a second hand. When the first needle is positioned at a predetermined position substantially perpendicular to the second needle, the first and second needles are configured to send / receive wireless signals.

The mobile and the gear are made of an electrically conductive material and define an electrical connection between the mobile and the communication module so that the mobile can act as an antenna for the transmission and / or reception of the wireless signal between the mobile. mobile and wireless communication module.
