Description

L'invention concerne un actionneur autonome pour l'entrainement entre plusieurs positions d'un écran de protection solaire ou d'occultation, tel qu'un volet.The invention relates to an autonomous actuator for driving between several positions of a sun protection or concealment screen, such as a shutter.

Les actionneurs pour volets ou stores roulants peuvent être autonomes et utiliser des batteries intégrées. Les batteries sont généralement prévues sous la forme d'ensemble de piles montées dans un boîtier séparé d'un corps ou carter de l'actionneur pour être remplacé plus facilement, en particulier lorsqu'il s'agit de piles non rechargeables.Actuators for shutters or roller blinds can be autonomous and use integrated batteries. The batteries are generally provided in the form of a set of cells mounted in a housing separate from a body or housing of the actuator in order to be replaced more easily, in particular in the case of non-rechargeable batteries.

WO 2013/162 818 décrit notamment un système d'entrainement de store à tube d'enroulement rotatif, dans lequel un ensemble de piles s'insère dans un tronçon de tube connecté à un carter contenant le moteur de l'actionneur. Ce tronçon de tube comprend une fenêtre au travers de laquelle les piles peuvent être extraites l'une après l'autre. Lorsque le store est complètement déployé, un utilisateur a accès à cette fenêtre. Ce système nécessite que le tronçon de tube contenant les piles tourne de concert avec le tube d'enroulement. WO 2013/162 818 describes in particular a system for driving a blind with a rotating winding tube, in which a set of batteries is inserted into a section of tube connected to a casing containing the motor of the actuator. This section of tube includes a window through which the stacks can be extracted one after the other. When the store is fully deployed, a user has access to this window. This system requires that the section of tube containing the batteries rotates in concert with the winding tube.

Il est également connu d'utiliser des batteries rechargeables par le biais d'un connecteur permettant la recharge des batteries par un dispositif externe. Toutefois, les batteries rechargeables ont une durée de vie limitée, ce qui implique leur remplacement au bout d'un certain nombre de cycles de charge et décharge. Dans le cas où les batteries sont logées dans le carter de l'actionneur, leur remplacement, s'il est éventuellement possible, nécessite le démontage de l'actionneur ou du moins de sa tête ou élément d'extrémité par lequel l'actionneur est fixé sur son support, ce qui crée des problèmes de rupture d'étanchéité de l'actionneur et l'entrée de poussières, ou bien un risque de détérioration de l'actionneur et de certains composants électroniques. Dans le cas où les batteries sont remplaçables en passant par la tête de l'actionneur, les moyens spécifiques d'accroche nécessaires à leur remplacement compliquent le montage et augmentent le diamètre total.It is also known to use rechargeable batteries by means of a connector allowing the batteries to be recharged by an external device. However, rechargeable batteries have a limited lifespan, which means replacing them after a certain number of charge and discharge cycles. If the batteries are housed in the casing of the actuator, their replacement, if it is possible, requires the disassembly of the actuator or at least of its head or end element by which the actuator is fixed to its support, which creates problems with the actuator breaking the seal and ingress of dust, or else a risk of deterioration of the actuator and certain electronic components. In the case where the batteries can be replaced by passing through the actuator head, the specific attachment means required for their replacement complicate assembly and increase the total diameter.

Une surface axiale est une surface perpendiculaire à l'axe X, tandis qu'une surface radiale est une surface cylindrique entourant l'axe X.In the remainder of the description, the terms “longitudinal”, “longitudinally”, “transverse”, “transversely”, “axial”, “axially” or “radial”, “radially” are used with reference to the axis X. An axial surface is a surface perpendicular to the X axis, while a radial surface is a cylindrical surface surrounding the X axis.

Dans l'espace intérieur E sont montés un moteur 6 et un ensemble réducteur 7. L'ensemble réducteur 7 est prolongé par un arbre de sortie 9 s'étendant à l'extérieur du carter 4 et tournant par rapport au carter 4 selon l'axe X pour l'entrainement en rotation d'un élément 11 représenté en traits pointillés à la figure 1, appartenant à l'écran ou au tube d'enroulement.In the interior space E are mounted a motor 6 and a reduction unit 7. The reduction unit 7 is extended by an output shaft 9 extending outside the housing 4 and rotating relative to the housing 4 according to the X axis for the rotation of an element 11 shown in dotted lines at the figure 1 , belonging to the screen or to the winding tube.

Dans l'espace intérieur E est également monté un circuit de contrôle 13 pour le pilotage du moteur 6. Ce circuit de contrôle 13 comprend une carte de circuit imprimé s'étendant longitudinalement dans le carter 4.In the interior space E is also mounted a control circuit 13 for driving the motor 6. This control circuit 13 comprises a printed circuit board extending longitudinally in the housing 4.

Dans l'espace intérieur E, est également monté un ensemble de batteries 15 relié au circuit de contrôle 13 par un câble 16 et un connecteur 17. Le connecteur 17 se connecte à un connecteur correspondant monté sur le circuit de contrôle 13. Ce câble 16 comprend deux lignes, l'une étant reliée au pôle positif de l'ensemble de batteries 15, l'autre étant reliée au pôle négatif de l'ensemble de batteries 15. Selon une variante non représentée, un circuit de gestion de charge peut être inséré entre le connecteur 16 et l'un des pôles de l'ensemble de batteries 15. Cet ensemble de batteries 15 fournit la puissance électrique nécessaire au fonctionnement du circuit de contrôle 13 et du moteur 6. L'ensemble de batteries 15 a une forme globalement cylindrique centrée sur l'axe X, et dont la forme épouse les contours internes du carter 4. En fonctionnement, le carter creux 4 est non rotatif, et de ce fait, l'ensemble de batteries 15 et le moteur 6 sont fixes en rotation par rapport au carter creux 4. De préférence, dans le cas de la variante selon laquelle l'ensemble de batteries 15 intègre un circuit de gestion de charge, la forme de l'ensemble de batteries 15 peut ne plus être complètement cylindrique, dans la mesure où le circuit de gestion de charge est placé et s'étend parallèlement aux batteries. Des aménagements à l'intérieur du carter creux, détaillés plus loin, sont alors prévus pour recevoir l'ensemble de batteries non cylindrique.In the interior space E, is also mounted a set of batteries 15 connected to the control circuit 13 by a cable 16 and a connector 17. The connector 17 is connected to a corresponding connector mounted on the control circuit 13. This cable 16 comprises two lines, one being connected to the positive pole of the set of batteries 15, the other being connected to the negative pole of the set of batteries 15. According to a variant not shown, a charge management circuit can be inserted between the connector 16 and one of the poles of the set of batteries 15. This set of batteries 15 provides the electrical power necessary for the operation of the control circuit 13 and of the motor 6. The set of batteries 15 has a shape generally cylindrical centered on the X axis, and the shape of which follows the internal contours of the casing 4. In operation, the hollow casing 4 is non-rotating, and therefore the battery assembly 15 and the motor 6 are fixed in rotation relative to the hollow casing x 4. Preferably, in the case of the variant according to which the set of batteries 15 integrates a charge management circuit, the shape of the set of batteries 15 may no longer be completely cylindrical, insofar as the circuit charge management is placed and extends parallel to the batteries. Arrangements inside the hollow casing, detailed below, are then provided to receive the set of non-cylindrical batteries.

Le carter creux 4 comprend un couvercle amovible permettant l'accès aux batteries de l'ensemble de batteries 15 et leur démontage en vue de leur remplacement. Dans le mode de réalisation de la figure 1, le carter 4 est formé par une coque inférieure 40 s'étendant d'une seule partie sur toute la longueur de l'actionneur 2, et une coque supérieure 42 assemblée à la coque inférieure 40 selon un plan longitudinal P2 de l'actionneur 2, ce plan P2 comprenant l'axe longitudinal X. La coque supérieure 42 est formée de deux parties 42A et 42B séparées axialement. La partie 42B s'étend parallèlement à l'axe longitudinal X au niveau de l'ensemble de batteries 15 et forme le couvercle démontable pour l'accès et le démontage de l'ensemble de batteries 15. La partie 42B a une longueur L au moins égale à la longueur totale L15 de l'ensemble de batterie 15. Ceci permet d'enlever l'ensemble de batteries 15 en un seul bloc et permet notamment d'utiliser un ensemble de batteries comprenant une pluralité de batteries cylindriques, maintenues l'une à l'autre par un film plastique. Si l'on prévoit un circuit de gestion de charge comme susmentionné, celui-ci peut également être maintenu à l'intérieur du film plastique, par exemple dans le prolongement des batteries, ou parallèlement aux batteries.The hollow casing 4 comprises a removable cover allowing access to the batteries of the set of batteries 15 and their dismantling with a view to their replacement. In the embodiment of the figure 1 , the casing 4 is formed by a lower shell 40 extending in a single part over the entire length of the actuator 2, and an upper shell 42 assembled to the lower shell 40 along a longitudinal plane P2 of the actuator 2 , this plane P2 comprising the longitudinal axis X. The upper shell 42 is formed of two parts 42A and 42B separated axially. The part 42B extends parallel to the longitudinal axis X at the level of the battery assembly 15 and forms the removable cover for accessing and disassembling the battery assembly 15. The part 42B has a length L at the less equal to the total length L15 of the battery assembly 15. This allows the battery assembly 15 to be removed as a single block and allows in particular to use a set of batteries comprising a plurality of cylindrical batteries, held together by a plastic film. If a charge management circuit is provided as mentioned above, this can also be kept inside the plastic film, for example in the extension of the batteries, or in parallel with the batteries.

La partie de carter 42B est maintenue en position par quatre pions, dont deux sont visibles à la figure 2 avec la référence 420, adaptés pour se loger dans des cavités 400, visibles à la figure 3, de forme complémentaire prévues sur la coque 40 opposée. La partie de coque 42B comprend également deux languettes élastiques de retenue dont une est visible à la figure 2 avec la référence 422, adaptées pour être engagées réversiblement dans des orifices 402 de la demi-coque opposée 40. Par réversiblement, on signifie que ces languettes 422 peuvent être engagées dans les orifices 402 lors de l'insertion de la partie 42B sur la partie 40, et retirées des orifices 402 par déformation élastique pour le démontage de la partie 42B. En variante, des nombres différents de pions 420 et de languettes 422 peuvent être prévus sur la partie amovible 42B. Les pions et languettes permettent de rigidifier le carter creux 4 de l'actionneur 2. Celui-ci doit en effet résister à des couples de torsion importants lorsque le moteur 6 est en fonctionnement. Le fait de multiplier les parties indépendantes du carter creux aurait tendance à fragiliser celui-ci en l'absence des pions et languettes et permettent d'éviter que les demi-coques 40 et 42 s'écartent l'une de l'autre.The housing part 42B is held in position by four pins, two of which are visible at the figure 2 with the reference 420, adapted to be housed in cavities 400, visible at the figure 3 , of complementary shape provided on the opposite shell 40. The shell portion 42B also includes two elastic retaining tabs, one of which is visible at the bottom. figure 2 with the reference 422, adapted to be reversibly engaged in orifices 402 of the opposite half-shell 40. By reversibly, it is meant that these tongues 422 can be engaged in the orifices 402 during the insertion of the part 42B on the part. 40, and removed from the orifices 402 by elastic deformation for the dismantling of the part 42B. As a variant, different numbers of pins 420 and of tabs 422 may be provided on the removable part 42B. The pins and tabs make it possible to stiffen the hollow casing 4 of the actuator 2. The latter must in fact withstand high torques when the motor 6 is in operation. The fact of increasing the number of independent parts of the hollow casing would tend to weaken the latter in the absence of the pins and tongues and make it possible to prevent the half-shells 40 and 42 from moving away from one another.

Selon un mode de réalisation avantageux, le carter 4, en particulier la surface intérieure du carter 4, présente des nervures transversales de renfort 44. Ces nervures sont présentes sur la demi-coque inférieure 40 mais également de façon non représentée sur les demi-coques 42A et 42B. Avantageusement, et de façon optionnelle, les demi-coques du carter 4 comprennent également des nervures de renfort longitudinales 46. Ces nervures transversales et longitudinales servent également de renfort et de rigidification du carter creux 4. Dans les exemples représentés, ces nervures transversales 44 et longitudinales 46 sont réparties de manière régulière sur l'ensemble de la surface intérieure 4. Alternativement, et pour éventuellement recevoir un ensemble de batteries non cylindrique, par exemple ayant une surépaisseur localisée, des aménagements irréguliers de ces nervures transversales et longitudinales peuvent être réalisés à l'intérieur du carter creux. Ainsi, les nervures peuvent n'être réparties que sur une portion inférieure à 340° ou avoir une épaisseur moindre dans une zone du carter ceux, permettant ainsi d'accommoder une surépaisseur localisée de l'ensemble de batteries 15.According to an advantageous embodiment, the casing 4, in particular the inner surface of the casing 4, has transverse reinforcing ribs 44. These ribs are present on the lower half-shell 40 but also in a manner not shown on the half-shells. 42A and 42B. Advantageously, and optionally, the half-shells of the casing 4 also include longitudinal reinforcing ribs 46. These transverse and longitudinal ribs also serve as reinforcement and stiffening of the hollow casing 4. In the examples shown, these transverse ribs 44 and longitudinal 46 are distributed in a regular manner over the whole of the interior surface 4. Alternatively, and to optionally receive a set of non-cylindrical batteries, for example having a localized extra thickness, irregular arrangements of these transverse and longitudinal ribs can be made to inside the hollow housing. Thus, the ribs can only be distributed over a portion of less than 340 ° or have a lesser thickness in a zone of the casing, thus making it possible to accommodate a localized extra thickness of the battery assembly 15.

Les composants de l'actionneur 2 sont localisés dans l'espace intérieur E selon l'ordre suivant, à partir d'une extrémité du carter 2 présentant une tête 19, située à l'opposé de l'arbre de sortie 9 : l'ensemble de batteries 15, le circuit de contrôle 13, le moteur 6 et l'ensemble réducteur 7.The components of the actuator 2 are located in the interior space E in the following order, from one end of the housing 2 having a head 19, located opposite the output shaft 9: the battery assembly 15, control circuit 13, motor 6 and reduction unit 7.

Cet espace intérieur renferme une carte de communication externe 21 permettant, par raccordement avec un dispositif extérieur non représenté, l'échange de données avec le circuit de contrôle 13. Avantageusement, la carte de communication 21 présente une forme en demi-lune s'étendant dans une partie de l'espace E19. En variante non représentée, la carte de communication 21 peut être localisée à un emplacement différent de l'actionneur 2. Elle est éventuellement optionnelle.The head 19 is an end element by which the actuator 1 is fixed on a support, not shown, such as a wall of a building. The head 19 is composed of a first part 19A which is integral with the lower shell 40, and a part 19B which is fixed to the part 19A. The parts 19A and 19B have a cylindrical shape defining an interior space E19. This internal space contains an external communication card 21 allowing, by connection with an external device not shown, the exchange of data with the control circuit 13. Advantageously, the communication card 21 has a shape of a half-moon extending. in part of the space E19. In a variant not shown, the communication card 21 can be located at a different location from the actuator 2. It is optionally optional.

Selon un aspect optionnel, la tête 19 peut comprendre un moyen d'interface 210, par exemple un bouton de programmation, prévu sur la carte de communication 21. Ce moyen d'interface 210 est accessible de l'extérieur de la tête 19 à travers un orifice 190 de la partie 19A, et une encoche 192 de la partie 19B.According to an optional aspect, the head 19 can comprise an interface means 210, for example a programming button, provided on the communication card 21. This interface means 210 is accessible from the outside of the head 19 through an orifice 190 of the part 19A, and a notch 192 of the part 19B.

Selon un mode de réalisation non représenté de l'invention, la tête 19 peut comprendre un moyen d'émission de signaux visuels, tels que des signaux lumineux, c'est-à-dire notamment un moyen de signalisation ou un moyen d'affichage, permettant de fournir des informations techniques sur l'état de l'actionneur 2, par exemple avantageusement sur le niveau de chargement de l'ensemble de batteries 15. Par exemple, ce moyen de signalisation peut être une diode de type LED fournissant des informations telles que : « charge ok », « charge faible », « pas de charge ». Le moyen d'émission de signaux visuels est prévu sur la carte de communication 21. Il dépasse à travers un orifice (non représenté) de la tête 19, similaire à l'orifice 190 de la partie 19A coopérant avec une encoche 192 de la partie 19B.According to a not shown embodiment of the invention, the head 19 may include a means for transmitting visual signals, such as light signals, that is to say in particular a signaling means or a display means. , making it possible to provide technical information on the state of the actuator 2, for example advantageously on the charge level of the set of batteries 15. For example, this signaling means can be an LED type diode providing information. such as: "charge ok", "low charge", "no charge". The means for transmitting visual signals is provided on the communication card 21. It protrudes through an orifice (not shown) of the head 19, similar to the orifice 190 of the part 19A cooperating with a notch 192 of the part. 19B.

De façon avantageuse, la longueur L de la partie 42B démontable permet également que l'ouverture du couvercle formé par cette partie 42B permette l'accès au circuit de contrôle 13. Avantageusement, cet accès permet le branchement d'un dispositif électronique extérieur non représenté à un connecteur du circuit de contrôle 13 permettant l'échange de données, ou bien la remise à zéro du circuit de contrôle 13 en cas de dysfonctionnement ou de mise à jour des paramètres de fonctionnement.Advantageously, the length L of the removable part 42B also allows the opening of the cover formed by this part 42B to allow access to the control circuit 13. Advantageously, this access allows the connection of an external electronic device, not shown. to a connector of the control circuit 13 allowing the exchange of data, or else the resetting of the control circuit 13 in the event of a malfunction or an update of the operating parameters.

Selon une variante non représentée, le circuit de contrôle 13 peut comprendre un bouton de remise à zéro actionnable par un installateur positionné au niveau de l'extrémité du circuit de contrôle tournée vers l'ensemble de batteries 15. Ainsi, ce bouton de remise à zéro est accessible à un utilisateur ou un installateur lorsque la partie 42B formant couvercle est retirée de l'actionneur 2.According to a variant not shown, the control circuit 13 may include a reset button that can be actuated by an installer positioned at the level of the end of the control circuit facing the set of batteries 15. Thus, this reset button is accessible to a user or an installer when the part 42B forming a cover is removed from the actuator 2.

Des actions sur le circuit de contrôle 13 sont aussi possibles grâce à au moins un orifice prévu à travers le carter 4 permettant le branchement d'un connecteur sur le circuit de contrôle 13 à travers le carter 4. Six orifices 46 de ce type sont présents sur le carter 4 au niveau de la coque inférieure 40.Actions on the control circuit 13 are also possible thanks to at least one orifice provided through the casing 4 allowing the connection of a connector to the control circuit 13 through the casing 4. Six orifices 46 of this type are present. on the housing 4 at the level of the lower shell 40.

Des passages de vis 51 sont prévus dans l'espace interne E prévu pour permettre la fixation des demi-coques 40 et 42 l'une à l'autre. Ces passages de vis 51 s'étendent perpendiculairement à l'axe X et de part et d'autre de celui-ci aux extrémités de l'ensemble de batteries 15. Lorsque l'ensemble de batteries 15 est mis en place dans le carter 4, il est maintenu en position axialement par la présence de ces passages de vis 51.Screw passages 51 are provided in the internal space E provided to allow the fixing of the half-shells 40 and 42 to one another. These screw passages 51 extend perpendicularly to the X axis and on either side of the latter at the ends of the set of batteries 15. When the set of batteries 15 is placed in the casing 4 , it is held in position axially by the presence of these screw passages 51.

Selon un aspect optionnel représenté à la figure 5, l'actionneur 2 peut comprendre un connecteur de recharge 194 de l'ensemble de batteries 15. Ce connecteur 194 est de préférence prévu sur la tête 19, et accessible à travers une fenêtre 196. En variante non représentée, ce connecteur 194 peut être placé à un endroit différent. Ce connecteur 194 permet la connexion à un dispositif de rechargement externe, tel qu'un chargeur externe relié à une prise secteur, un panneau photovoltaïque, etc. Le connecteur de recharge 194 est relié à ces conducteurs, eux-mêmes en contact électrique avec des bornes électriques de l'ensemble de batteries 15. La gestion de la charge de l'ensemble de batteries peut être gérées soit par un chargeur externe, connecté au connecteur de recharge, soit par le circuit de gestion de charge correspondant sur la carte de communication 21, sur le circuit de contrôle 13, ou par un circuit de gestion de charge dédié faisant partie de l'ensemble de batteries 15 comme expliqué précédemment.According to an optional aspect shown in figure 5 , the actuator 2 may include a connector 194 for recharging the battery assembly 15. This connector 194 is preferably provided on the head 19, and accessible through a window 196. In a variant not shown, this connector 194 may be placed in a different location. This connector 194 allows connection to an external recharging device, such as an external charger connected to a mains socket, a photovoltaic panel, etc. The recharging connector 194 is connected to these conductors, themselves in electrical contact with the electrical terminals of the set of batteries 15. The management of the charge of the set of batteries can be managed either by an external charger, connected to the recharging connector, either by the corresponding load management circuit on the communication card 21, on the control circuit 13, or by a dedicated load management circuit forming part of the set of batteries 15 as explained previously.

Une nappe électrique souple 18, comprenant plusieurs pistes, relie la carte de communication 21 au circuit de contrôle 13. Certaines de ces pistes peuvent être utilisées pour la transmission de l'alimentation électrique vers l'ensemble de batteries 15. D'autres pistes servent au transport de données entre la carte de communication 21 et le circuit de contrôle 13. Une ou plusieurs pistes peuvent être utilisées en tant qu'antenne 198 d'émission/réception d'ondes radios.A flexible electric sheet 18, comprising several tracks, connects the communication card 21 to the control circuit 13.

Other tracks are used. to the transport of data between the communication card 21 and the control circuit 13. One or more tracks can be used as antenna 198 for transmitting / receiving radio waves.

D'autres modes de réalisation de l'invention sont représentés sur les figures 6 à 9. Dans ces modes de réalisation, les éléments communs au premier mode de réalisation portent les mêmes références et fonctionnent de la même manière. Seules les différences par rapport au premier mode de réalisation sont décrites ci-après.Other embodiments of the invention are shown in the figures 6 to 9 . In these embodiments, the elements common to the first embodiment bear the same references and operate in the same way. Only the differences from the first embodiment are described below.

Dans un deuxième mode de réalisation représenté aux figures 6 et 7, le carter 4 est formé par deux demi-coques 40 et 42. Dans ce cas, la coque supérieure 42 est formée d'une seule pièce sur la longueur de l'actionneur 2 et l'une des deux demi-coques, en l'occurrence la demi-coque 42, présente un évidement 424, et une trappe 426 refermant cet évidement 424. La trappe 426 forme le couvercle démontable permettant l'accès à l'ensemble de batteries 15. Elle s'étend longitudinalement suivant l'axe longitudinal X du carter creux 4. Avantageusement, la trappe 426 peut être prévue en matériau plastique.In a second embodiment shown in figures 6 and 7 , the casing 4 is formed by two half-shells 40 and 42. In this case, the upper shell 42 is formed in one piece over the length of the actuator 2 and one of the two half-shells, in l 'occurrence the half-shell 42, has a recess 424, and a hatch 426 closing this recess 424. The hatch 426 forms the removable cover allowing access to the set of batteries 15. It extends longitudinally along the axis longitudinal X of the hollow casing 4. Advantageously, the hatch 426 can be made of plastic material.

La trappe 426 est fixée à la partie principale du carter 4 par, d'un côté, une pièce d'accroche 426a, et de l'autre côté, une languette élastique 426b qui se loge dans une cavité 428 du carter 4. Cette cavité 428 est prévue dans la partie 42 sur la figure 7. La languette élastique 86b peut être déformée élastiquement par un opérateur pour la désengager de la cavité 88 et ainsi retirer la trappe 426 de manière à accéder à l'ensemble de batteries 15.The hatch 426 is fixed to the main part of the casing 4 by, on one side, a hooking part 426a, and on the other side, an elastic tongue 426b which is housed in a cavity 428 of the casing 4. This cavity 428 is provided for in part 42 on the figure 7 . The elastic tab 86b can be elastically deformed by an operator to disengage it from the cavity 88 and thus remove the hatch 426 so as to access the battery assembly 15.

Selon une variante compatible avec tous les autres modes de réalisation, à la place de l'antenne 198, on peut prévoir une antenne d'émission/réception d'ondes radios, peut être réalisée sous forme d'un câble coaxial, non représenté, connecté au circuit de contrôle 13. Ce câble coaxial est logé dans une gorge longitudinale 49, représentée à la figure 7, qui est formée par des interruptions des nervures de renfort transversales 44 du carter 4 et passe sous l'ensemble de batterie 15.According to a variant compatible with all the other embodiments, instead of the antenna 198, it is possible to provide an antenna for transmitting / receiving radio waves, which may be produced in the form of a coaxial cable, not shown, connected to the control circuit 13. This coaxial cable is housed in a longitudinal groove 49, shown on figure 7 , which is formed by interruptions of the transverse reinforcing ribs 44 of the housing 4 and passes under the battery assembly 15.

L'antenne d'émission/réception d'ondes radios peut ainsi passer au travers de la tête et dépasser à l'extérieur du carter 4. En variante non représentée, cette antenne peut être complètement intégrée à l'intérieur du carter 4 et/ou de la tête 19.The radio wave transmit / receive antenna can thus pass through the head and protrude outside the casing 4. In a variant not shown, this antenna can be completely integrated inside the casing 4 and / or head 19.

Un troisième mode de réalisation est représenté sur la figure 8. Dans ce mode de réalisation, le carter creux 4 est un tube cylindrique monobloc. Le couvercle donnant accès à l'ensemble de batterie 15 est formé par une trappe similaire à la trappe 426.A third embodiment is shown in figure 8 . In this embodiment, the hollow casing 4 is a one-piece cylindrical tube. The cover giving access to the battery assembly 15 is formed by a hatch similar to the hatch 426.

La figure 9 illustre schématiquement un quatrième mode de réalisation d'un actionneur 2, qui comprend de préférence toutes les caractéristiques de l'un des actionneurs 2 décrits dans ce qui précède, incluant un connecteur de recharge 194, un ensemble de batteries 15, ainsi qu'un circuit de gestion de charge 22. Dans ce mode de réalisation de la figure 9, le connecteur de recharge 194 est avantageusement un connecteur trois points, définissant trois lignes de connexion, dont une ligne commune N, pour être à la fois compatible avec une alimentation par chargeur externe C et par panneau photovoltaïque PV. Lors d'une alimentation avec panneau photovoltaïque PV, la connexion se fait alors sur une première ligne P1 et la ligne commune N du connecteur trois points. Lors d'une alimentation avec le chargeur externe C, la connexion se fait sur une deuxième ligne P2 et la ligne commune N. Le connecteur de recharge comprend également des moyens de détrompage mécanique 197, tels qu'une épaisseur localisée, rendant le connecteur non symétrique. Le connecteur correspondant du chargeur externe ou du panneau photovoltaïque étant également munis des moyens complémentaires de détrompage mécanique 197, le circuit de gestion de la charge de l'ensemble de batteries 15 est informé de la nature du dispositif de rechargement externe par le biais des lignes alimentées. Il est ainsi possible par exemple de prévoir une adaptation du fonctionnement du circuit de contrôle 13 ou de la carte de communication 21, une adaptation des informations transmises notamment à l'attention d'un utilisateur ou une adaptation de la gestion de la charge en fonction de cette nature du dispositif de rechargement externe. Par exemple, le moyen de signalisation, qui se présente par exemple sous la forme d'une diode lumineuse, peut clignoter lorsque l'ensemble de batterie est rechargé à partir d'un chargeur externe et ne pas clignoter, ou clignoter à une fréquence inférieure, lorsque l'ensemble de batterie est rechargé à partir d'un panneau photovoltaïque.The figure 9 schematically illustrates a fourth embodiment of an actuator 2, which preferably comprises all the features of one of the actuators 2 described in the foregoing, including a recharging connector 194, a set of batteries 15, as well as a charge management circuit 22. In this embodiment of the figure 9 , the recharging connector 194 is advantageously a three-point connector, defining three connection lines, including a common line N, to be both compatible with a power supply by an external charger C and by a photovoltaic PV panel. When powering with a PV photovoltaic panel, the connection is then made on a first line P1 and the common line N of the three-point connector. When power is supplied with the external charger C, the connection is made on a second line P2 and the common line N. The charging connector also includes mechanical keying means 197, such as a localized thickness, making the connector non-standard. symmetrical. Since the corresponding connector of the external charger or of the photovoltaic panel is also provided with additional mechanical keying means 197, the charge management circuit of the set of batteries 15 is informed of the nature of the external recharging device by means of the lines. powered. It is thus possible for example to provide for an adaptation of the operation of the control circuit 13 or of the communication card 21, an adaptation of the information transmitted in particular to the attention of a user or an adaptation of the management of the load according to of this nature of the external recharging device. For example, the signaling means, which is for example in the form of a light diode, may flash when the battery pack is being recharged from an external charger and not flash, or flash at a lower frequency. , when the battery pack is recharged from a photovoltaic panel.

Selon un autre mode de réalisation non représenté de l'invention, le circuit de contrôle 13 comporte avantageusement un dispositif de comptage des rotations du rotor du moteur 6. Ce dispositif peut, par exemple, comprendre un ou plusieurs capteurs à effet Hall détectant les rotations d'un rotor du moteur 6, et connectés sur la carte de circuit imprimé formant le circuit de contrôle 13.According to another embodiment of the invention, not shown, the control circuit 13 advantageously comprises a device for counting the rotations of the rotor of the motor 6. This device may, for example, comprise one or more Hall effect sensors detecting the rotations. of a rotor of the motor 6, and connected to the printed circuit board forming the control circuit 13.

Indépendamment de ce qui précède, on prévoit un actionneur autonome pour l'entrainement entre plusieurs positions d'un écran de protection solaire ou d'occultation, l'actionneur comprenant un carter creux délimitant un espace intérieur, alors que dans cet espace intérieur sont montés :

  • un moteur et un ensemble réducteur
  • un circuit de contrôle pour le pilotage du moteur,
  • un ensemble de batterie relié au circuit de contrôle,
Independently of the foregoing, an autonomous actuator is provided for driving between several positions of a solar protection or concealment screen, the actuator comprising a hollow casing delimiting an interior space, while in this interior space are mounted :
  • a motor and a reduction unit
  • a control circuit for driving the motor,
  • a battery assembly connected to the control circuit,

En outre, le carter creux comporte un arbre de sortie tournant par rapport au carter pour l'entrainement en rotation d'un élément de l'écran, alors que l'actionneur comprend un connecteur de recharge de l'ensemble de batteries comprenant au moins trois lignes de connexion et des moyens de détrompage mécanique.In addition, the hollow casing comprises an output shaft rotating relative to the casing for driving in rotation an element of the screen, while the actuator comprises a connector for recharging the set of batteries comprising at least three connection lines and mechanical foolproofing means.

Grâce à ces dispositions, il est ainsi possible de recharger l'ensemble de batteries par le biais d'au moins deux dispositifs de rechargement externe de nature différente, par exemple un chargeur externe relié à une prise secteur et un panneau photovoltaïque, et de différencier la nature du dispositif de rechargement par la connexion de celui-ci aux différentes lignes du connecteur de recharge de l'actionneur. En effet, seules deux lignes sont utiles pour la recharge de l'ensemble de batteries. Ainsi, si l'actionneur détecte une alimentation sur deux premières lignes, il pourra en déduire un comportement adapté à un premier dispositif de rechargement et si l'actionneur détecte une alimentation sur une première et une troisième ligne, ou deux autres lignes, il pourra en déduire un comportement adapté à un deuxième dispositif de rechargement.Thanks to these arrangements, it is thus possible to recharge the set of batteries by means of at least two external recharging devices of a different nature, for example an external charger connected to a mains socket and a photovoltaic panel, and to differentiate the nature of the recharging device by connecting it to the different lines of the actuator charging connector. Indeed, only two lines are useful for recharging the set of batteries. Thus, if the actuator detects a power supply on two first lines, it will be able to deduce therefrom a behavior adapted to a first recharging device and if the actuator detects a power supply on a first and a third line, or two other lines, it can deduce a behavior suitable for a second reloading device.

Cet actionneur autonome comprend optionnellement et avantageusement une ou plusieurs autres des caractéristiques décrites dans ce qui précède.This autonomous actuator optionally and advantageously comprises one or more other characteristics described in the above.
