Description

Domaine techniqueTechnical area

Le domaine de l'invention est celui des véhicules automobiles.The field of the invention is that of motor vehicles.

Plus précisément, l'invention concerne les équipements mis en œuvre dans les véhicules automobiles dont le déplacement est assuré par des moyens d'actionnement ou de manœuvre comprenant un motoréducteur actionnant un câble par le biais d'un pignon d'entraînement.More precisely, the invention relates to the equipment used in motor vehicles, the movement of which is ensured by actuation or maneuvering means comprising a geared motor actuating a cable by means of a drive pinion.

Ces équipements sont, par exemple, les baies vitrées pour les pavillons de véhicules, connus sous le nom « baie flush », qui conçus pour être montés de façon affleurante avec la carrosserie, ou bien les moyens d'occultation totale ou partielle (tels que les stores à enrouleur) des surfaces vitrées de véhicules.These items of equipment are, for example, bay windows for vehicle pavilions, known under the name “flush bay”, which are designed to be mounted flush with the bodywork, or else the total or partial concealment means (such as roller blinds) glass surfaces of vehicles.

Plus précisément encore, l'invention concerne la conservation des moyens d'actionnement ou de manœuvre de tels équipements dans une position prédéterminée, avant leur montage définitif et leur première utilisation dans un véhicule, ou bien lors d'une réparation.More precisely still, the invention relates to the conservation of the means for actuating or maneuvering such equipment in a predetermined position, before their final assembly and their first use in a vehicle, or else during a repair.

État de la techniqueState of the art

Les baies vitrées de surface importante sont devenues des éléments incontournables des véhicules automobiles modernes. Ménagées dans la carrosserie, elles permettent de proposer aux utilisateurs des véhicules au design nouveau et à l'habitacle lumineux.Large bay windows have become essential elements of modern motor vehicles. Spared in the bodywork, they make it possible to offer users vehicles with a new design and bright interiors.

On propose en particulier des pavillons de véhicules présentant des surfaces vitrées de plus en plus conséquentes, correspondant le cas échéant à l'intégralité ou à une partie essentielle du pavillon.In particular, vehicle pavilions are proposed having increasingly large glass surfaces, where appropriate corresponding to all or an essential part of the pavilion.

Ces baies vitrées comprennent un panneau fixe et un panneau mobile pouvant être déplacé par rapport au panneau fixe, pour obturer ou libérer une ouverture définie à côté du panneau fixe.These bay windows include a fixed panel and a movable panel that can be moved relative to the fixed panel, to close or release an opening defined next to the fixed panel.

Les différents mouvements du panneau mobile sont contrôlés à partir du déplacement de deux éléments d'actionnement appelés navettes, une de chaque côté du pavillon, qui sont mobiles selon une seule direction, le long et à l'intérieur de rails prévus à cet effet.The various movements of the movable panel are controlled from the movement of two actuating elements called shuttles, one on each side of the pavilion, which are movable in a single direction, along and inside rails provided for this purpose.

Ce déplacement peut être motorisé, par exemple via un motoréducteur, contrôlant le déplacement des deux navettes de chacun des rails par le biais d'un pignon d'entraînement d'un câble relié aux navettes.This movement can be motorized, for example via a geared motor, controlling the movement of the two shuttles of each of the rails by means of a drive pinion of a cable connected to the shuttles.

Il est également connu d'équiper les surfaces vitrées de véhicules de moyens d'occultation totale ou partielle. Il peut en effet être nécessaire de protéger les occupants des effets du soleil. Parmi les moyens d'occultation connus (store d'occultation à enrouleur ou vélum par exemple), on distingue les mises en œuvre manuelles et motorisées, dans lesquelles le déplacement de la toile d'occultation, ou d'un vélum, entre une position déployée et une position repliée, est assuré par des moyens d'entrainement motorisé, typiquement un motoréducteur. Un tel motoréducteur actionne, par le biais d'un pignon d'entraînement, deux câbles respectivement connectés à chacune des extrémités de la barre de tirage de la toile d'occultation.It is also known to equip the glazed surfaces of vehicles with total or partial concealment means. It may indeed be necessary to protect the occupants from the effects of the sun. Among the known blackout means (roller blackout blind or awning for example), there are manual and motorized implementations, in which the displacement of the blackout fabric, or of a canopy, between a position deployed and a folded position, is provided by motorized drive means, typically a geared motor. Such a geared motor actuates, by means of a drive pinion, two cables respectively connected to each of the ends of the pulling bar of the blackout fabric.

En règle générale, le motoréducteur n'est relié à l'équipement qu'au moment de l'installation ou du montage définitif de l'équipement dans le véhicule.As a general rule, the geared motor is not connected to the equipment until the installation or final assembly of the equipment in the vehicle.

De la même façon, lorsqu'il est nécessaire de réparer l'équipement, le motoréducteur est désolidarisé de l'équipement. Dans ce cas de figure, la câble et le pignon d'entrainement sont libres de mouvement.Likewise, when it is necessary to repair the equipment, the gear motor is disconnected from the equipment. In this case, the cable and the drive pinion are free to move.

Il est donc nécessaire de prévoir une pièce spécifique, telle une cale, pour bloquer/maintenir temporairement le système de manœuvre qui pourrait sans la présence de cette pièce être endommagé pendant le transport.It is therefore necessary to provide a specific part, such as a wedge, to temporarily block / maintain the operating system which could, without the presence of this part, be damaged during transport.

Cette pièce, qui est jetable, doit bien évidemment être retirée par l'opérateur une fois que le motoréducteur est relié à l'équipement lors de l'installation sur un véhicule. Si l'opérateur oublie de l'enlever, il y a un risque d'endommager l'équipement (le moteur en particulier).This part, which is disposable, must of course be removed by the operator once the geared motor is connected to the equipment during installation on a vehicle. If the operator forgets to remove it, there is a risk of damaging the equipment (especially the engine).

Objectifs de l'inventionObjectives of the invention

La présente invention a pour objectif de fournir un système de blocage temporaire des moyens d'actionnement ou de manœuvre d'un équipement (moyens d'occultation ou panneau vitré mobile, par exemple), qui soit particulièrement simple à mettre en œuvre dans un véhicule.The object of the present invention is to provide a system for temporarily blocking the means for actuating or maneuvering an item of equipment (concealment means or movable glass panel, for example), which is particularly simple to implement in a vehicle. .

Un autre objectif de l'invention est de fournir un tel système de blocage temporaire qui permette un découplage rapide, ne nécessitant pas d'outil.Another objective of the invention is to provide such a temporary locking system which allows rapid decoupling, requiring no tool.

Encore un autre objectif de l'invention est de fournir un tel système de blocage temporaire qui soit peu coûteux à mettre en place dans un véhicule et qui génère un encombrement et un poids minimal.Yet another objective of the invention is to provide such a temporary locking system which is inexpensive to install in a vehicle and which generates a bulk and minimal weight.

Exposé de l'inventionDisclosure of the invention

Ces objectifs sont atteints à l'aide d'un dispositif de blocage provisoire d'un système de manœuvre motorisé d'un équipement d'un véhicule automobile, le système de manœuvre comprenant un pignon d'entraînement d'un câble destiné à être entrainée en rotation autour d'un axe par un motoréducteur, le câble étant agencé pour d'une part coopérer avec la denture extérieure dudit pignon d'entraînement et pour d'autre part entrainer en translation au moins un élément d'actionnement de l'équipement, le pignon d'entraînement et le câble étant disposés dans un carter.These objectives are achieved using a temporary locking device for a motorized maneuvering system of a piece of equipment in a motor vehicle, the maneuvering system comprising a drive pinion of a cable intended to be driven in rotation around an axis by a geared motor, the cable being arranged to, on the one hand, cooperate with the external teeth of said drive pinion and, on the other hand, to drive in translation at least one actuating element of the equipment , the drive pinion and the cable being arranged in a housing.

Selon invention, le dispositif de blocage comprend un ressort de compression selon l'axe A du pignon d'entraînement contre une face intérieure du carter et des moyens de blocage du pignon d'entraînement ménagés sur ladite face intérieure du carter et destinés à coopérer avec le pignon d'entraînement sous l'effet du ressort de compression lorsque le motoréducteur est désolidarisé du carter.According to the invention, the locking device comprises a compression spring along the axis A of the drive pinion against an inner face of the casing and means for locking the drive pinion provided on said inner face of the casing and intended to cooperate with the drive pinion under the effect of the compression spring when the geared motor is disconnected from the housing.

Ainsi, l'invention propose des moyens de blocage temporaire du système de manœuvre d'un équipement de véhicule avant l'installation ou le montage définitif de l'équipement dans un véhicule, lorsque le motoréducteur du système de manœuvre est démonté.Thus, the invention proposes means for temporarily blocking the operating system of a vehicle equipment item before the installation or final assembly of the equipment in a vehicle, when the geared motor of the operating system is removed.

Ces moyens de blocage temporaire permettent de maintenir les moyens de manœuvre de l'équipement dans une position prédéterminée de blocage, jusqu'au montage après réparation ou à la première utilisation de l'équipement.These temporary blocking means make it possible to maintain the equipment maneuvering means in a predetermined blocking position, until assembly after repair or when the equipment is used for the first time.

Dans cette position prédéterminée de blocage, la denture du pignon d'entrainement est en prise (ou prend appui) avec des moyens de blocage ménagés sur la surface intérieure du carter logeant le pignon d'entrainement et le câble, ce qui empêche tout mouvement intempestif de ces derniers, et minimise donc les risques de détérioration.

Description de l'inventionDescription of the invention

L'invention est décrite par la suite lorsqu'elle est mise en œuvre en relation avec un toit ouvrant de véhicule.The invention is described below when it is implemented in relation to a vehicle sunroof.

Une telle baie vitrée comprend de façon classique un panneau fixe et un panneau mobile pouvant être déplacé par rapport au panneau fixe, pour obturer ou libérer une ouverture définie à côté du panneau fixe.Such a bay window conventionally comprises a fixed panel and a movable panel that can be moved relative to the fixed panel, to close or release an opening defined next to the fixed panel.

Les différents mouvements du panneau mobile sont contrôlés à partir du déplacement de deux navettes, une de chaque côté du pavillon, mobiles selon une seule direction, le long et à l'intérieur de rails prévus à cet effet. Ce déplacement est assuré par un système de manœuvre motorisé, comprenant notamment un motoréducteur, contrôlant le déplacement des deux navettes par le biais d'un pignon d'entraînement et d'un ou de deux câbles de transmission du mouvement du moteur vers les navettes.The various movements of the mobile panel are controlled from the movement of two shuttles, one on each side of the pavilion, movable in a single direction, along and inside rails provided for this purpose. This movement is ensured by a motorized maneuvering system, comprising in particular a geared motor, controlling the movement of the two shuttles by means of a drive pinion and one or two cables transmitting the movement of the motor to the shuttles.

La figure 1 est une vue éclatée des éléments constituant le dispositif de manœuvre motorisé de l'invention.The figure 1 is an exploded view of the elements constituting the motorized maneuvering device of the invention.

Il comprend un moteur d'actionnement, appelé par la suite motoréducteur, 2 et un support moteur 4 présentant un logement 41 cylindrique dans lequel sont destinés à être logés un ressort 6 de compression, un pignon d'entraînement 7 d'un câble 5 actionnant en translation les navettes du panneau mobile et un pignon primaire, ou intermédiaire, 22 monté sur l'arbre de sortie 23 du motoréducteur 2, dit pignon primaire, les deux pignons 7, 22 formant réducteur de vitesse.It comprises an actuating motor, hereinafter called a geared motor, 2 and a motor support 4 having a cylindrical housing 41 in which a compression spring 6 is intended to be housed, a drive pinion 7 of an actuating cable 5. in translation the shuttles of the movable panel and a primary or intermediate pinion 22 mounted on the output shaft 23 of the geared motor 2, called the primary pinion, the two pinions 7, 22 forming a speed reducer.

Le support moteur 4 comprend en outre une rainure 42 de réception et de maintien du câble 5 de transmission du mouvement du motoréducteur 2 vers les navettes et de sa gaine 8. L'arbre de sortie 23 du motoréducteur 2 est relié au pignon primaire 22 destiné à engrener avec le pignon d'entraînement 7 du câble 5. Ce câble 5 est donc un des éléments qui transmettent l'énergie de traction/compression du motoréducteur 2 aux navettes pour mettre en mouvement le déplacement du panneau mobile. Le motoréducteur 2 commande ainsi le déplacement du panneau mobile et donc la fermeture ou l'ouverture de l'ouverture ménagée dans le panneau fixe.The motor support 4 further comprises a groove 42 for receiving and holding the cable 5 for transmitting the movement of the geared motor 2 to the shuttles and its sheath 8. The output shaft 23 of the geared motor 2 is connected to the primary pinion 22 intended for to mesh with the drive pinion 7 of the cable 5. This cable 5 is therefore one of the elements which transmit the traction / compression energy from the geared motor 2 to the shuttles in order to set in motion the movement of the movable panel. The geared motor 2 thus controls the movement of the movable panel and therefore the closing or opening of the opening made in the fixed panel.

Le couple et la vitesse de rotation du pignon d'entraînement 7 sont déterminés en fonction des forces et courses à prendre en compte. Le pignon d'entraînement 7, le pignon primaire 22 et l'arbre de sortie 23 du motoréducteur 2 sont mobiles en rotation autour de l'axe A.The torque and the speed of rotation of the drive pinion 7 are determined as a function of the forces and strokes to be taken into account. The drive pinion 7, the primary pinion 22 and the output shaft 23 of the gear motor 2 are movable in rotation about the axis A.

Le câble 5 circule à l'intérieur de gaines 8 arrêtées en butée contre le support de moteur 4.The cable 5 runs inside sheaths 8 stopped in abutment against the motor support 4.

Une première gaine pour le brin actif du câble 5 est en liaison avec les rails et une deuxième gaine pour le brin mort du câble 5 stocke et protège le surplus du câble.A first sheath for the active strand of the cable 5 is connected with the rails and a second sheath for the dead end of the cable 5 stores and protects the surplus of the cable.

Le pignon d'entraînement 7 comprend un corps de forme globalement annulaire muni de dents à sa périphérie externe (denture hélicoïdale) et de dents sur sa périphérie interne.The drive pinion 7 comprises a body of generally annular shape provided with teeth at its outer periphery (helical teeth) and teeth on its inner periphery.

Le câble 5 présente une cannelure hélicoïdale 51 engrenant avec la denture extérieure 71 du pignon d'entraînement 7. La denture intérieure 72 du pignon d'entraînement 7 (à denture droite dans cet exemple) est destinée à coopérer avec le pignon primaire 22 prenant la forme d'une roue dentée (à denture droite dans cet exemple) présentant un corps de forme globalement annulaire muni de dents à sa périphérie externe.The cable 5 has a helical spline 51 meshing with the external teeth 71 of the drive pinion 7. The internal teeth 72 of the drive pinion 7 (with straight teeth in this example) is intended to cooperate with the primary pinion 22 taking the in the form of a toothed wheel (with straight teeth in this example) having a body of generally annular shape provided with teeth at its outer periphery.

Le support moteur 4 permet le positionnement du ou des câbles 5, du pignon d'entraînement 7, des gaines 8, et d'un ressort de compression 6 axiale destiné à plaquer le pignon d'entraînement 7 contre un couvercle 3. Ce couvercle 3 vient se fixer sur le support moteur 4 de sorte à former un carter. Le couvercle 3 est pourvu de moyens de blocage du pignon d'entraînement 7 lorsque le motoréducteur 2 est désolidarisé du support moteur 4.The motor support 4 allows the positioning of the cable or cables 5, the drive pinion 7, the sheaths 8, and an axial compression spring 6 intended to press the drive pinion 7 against a cover 3. This cover 3 comes to be fixed on the engine support 4 so as to form a casing. The cover 3 is provided with means for blocking the drive pinion 7 when the geared motor 2 is disconnected from the motor support 4.

Ces moyens de blocage prennent ici la forme de creux formant une couronne qui sont usinés sur la surface intérieure du couvercle 3, autour de l'ouverture circulaire 31.These locking means here take the form of hollows forming a ring which are machined on the inner surface of the cover 3, around the circular opening 31.

Le bord latéral des dents de la denture extérieure 71 du pignon d'entraînement 7 est destiné à coopérer avec la couronne de creux 32 de forme correspondante formant les moyens de blocage, comme cela est illustré sur la figure 4.The lateral edge of the teeth of the external teeth 71 of the drive pinion 7 is intended to cooperate with the hollow ring 32 of corresponding shape forming the locking means, as illustrated in FIG. figure 4 .

Plus précisément, lorsque le motoréducteur 2 est retiré, le ressort de compression 6 pousse le pignon d'entraînement 7 contre la surface intérieure du couvercle 3 selon l'axe A de sorte que le bord latéral des dents de la denture extérieure 71 du pignon d'entraînement 7 s'enchevêtre avec les reliefs en creux ménagés sur la surface intérieure du couvercle 3 (figures 2 et 4). Le pignon d'entraînement 7 est alors bloqué en rotation et le câble 5 ne peut plus coulisser. Ceci permet d'assurer un blocage automatique du pignon d'entraînement 7 en cas d'absence du motoréducteur 2. Ceci est notamment utile lors du transport du système de manœuvre avant son montage définitif sur un véhicule ou lors d'une réparation.More precisely, when the geared motor 2 is withdrawn, the compression spring 6 pushes the drive pinion 7 against the inner surface of the cover 3 along the axis A so that the lateral edge of the teeth of the outer teeth 71 of the pinion d 'drive 7 becomes entangled with the recessed reliefs formed on the inner surface of the cover 3 ( figures 2 and 4 ). The drive pinion 7 is then locked in rotation and the cable 5 can no longer slide. This ensures automatic locking of the drive pinion 7 in the absence of the gear motor 2. This is particularly useful when transporting the maneuvering system before its final assembly on a vehicle or during a repair.

En vissant le motoréducteur 2 sur le support moteur 4 (figure 3), l'arbre de sortie 23 et le pignon primaire 22 traversent l'ouverture circulaire 31 du couvercle 3. Le pignon primaire 22 vient s'insérer dans le pignon d'entraînement 7 de sorte à engrener avec ce dernier, et le motoréducteur 2 pousse le pignon d'entraînement 7 en comprimant le ressort de compression 6 dans le logement 41 cylindrique de sorte que le pignon d'entraînement 7 se libère des reliefs de blocage du couvercle 3. En d'autres termes, le ressort de compression 6 est comprimé par le montage du motoréducteur 2. Le pignon d'entraînement 7 est alors libre de tourner et le câble 5 peut alors coulisser pour piloter les navettes pour mettre en mouvement le déplacement du panneau mobile.By screwing gearmotor 2 onto motor support 4 ( figure 3 ), the output shaft 23 and the primary pinion 22 pass through the circular opening 31 of the cover 3. The primary pinion 22 fits into the drive pinion 7 so as to mesh with the latter, and the gear motor 2 pushes the drive pinion 7 by compressing the compression spring 6 in the cylindrical housing 41 so that the drive pinion 7 is released from the locking reliefs of the cover 3. In other words, the compression spring 6 is compressed by the assembly of the gear motor 2. The drive pinion 7 is then free to rotate and the cable 5 can then slide to drive the shuttles to set in motion the movement of the mobile panel.

Le dispositif de l'invention permet un maintien temporaire en position bloquée du système de manœuvre motorisé d'un équipement d'un véhicule automobile, le ressort ayant pour rôle de plaquer le pignon d'entraînement 7 contre la surface intérieure du carter, et plus précisément du couvercle 3, pour désactiver ce dernier et empêcher tout mouvement intempestif du pignon d'entraînement 7 et du câble 5.The device of the invention allows a temporary maintenance in the blocked position of the motorized maneuvering system of a piece of equipment of a motor vehicle, the spring having the role of pressing the drive pinion 7 against the inner surface of the housing, and more precisely of the cover 3, to deactivate the latter and prevent any unwanted movement of the drive pinion 7 and of the cable 5.

On assure donc un déblocage automatique par le montage du motoréducteur 2 sans avoir besoin d'enlever une pièce ou effectuer une action spécifique.Automatic release is therefore ensured by mounting the geared motor 2 without having to remove a part or perform a specific action.

On note que l'effort du ressort de compression 6 axial sur le pignon d'entraînement 7 est transmis au pignon primaire 22 du motoréducteur 2 et participe ainsi à la réduction du bruit lors de l'inversion entre la marche avant et la marche arrière (menant/mené) dans le motoréducteur 2.It is noted that the force of the axial compression spring 6 on the drive pinion 7 is transmitted to the primary pinion 22 of the geared motor 2 and thus contributes to the reduction of noise during the reversal between forward and reverse gear ( driving / driven) in the gearmotor 2.

Le principe de l'invention est valable que le système de manœuvre motorisé d'un équipement d'un véhicule automobile mette en œuvre un ou deux câbles « poussé/tiré » (câble de traction et câble de poussée) reliés à une ou deux navettes de coulissement disposées dans des rails de coulissement d'une baie vitrée. Ce ou ces câbles sont les éléments qui transmettent l'énergie de traction/compression du motoréducteur à la ou les navettes pour mettre en mouvement le déplacement du panneau mobile. Selon le cas de figure, le système met en œuvre une ou deux gaines de câble (brin actif) en liaison avec les rails et une ou deux gaines qui stockent et protègent le surplus de câble (brin mort).The principle of the invention is valid if the motorized maneuvering system of a piece of equipment in a motor vehicle implements one or two “push / pull” cables (pull cable and push cable) connected to one or two shuttles. sliding rails arranged in sliding rails of a bay window. This or these cables are the elements which transmit the traction / compression energy of the geared motor to the shuttle or shuttles to set in motion the movement of the mobile panel. Depending on the situation, the system uses one or two cable sheaths (active strand) in connection with the rails and one or two sheaths which store and protect the excess cable (dead strand).

Le mode de réalisation décrit ci-dessus s'applique à une baie vitrée de toit ouvrant de véhicule. Il pourrait s'agir d'une baie mise en œuvre sur une paroi latérale d'un véhicule automobile. Il est également évident que l'invention peut s'appliquer de la même façon à d'autres structures présentant une paroi dans laquelle est définie une baie, comme, par exemple, une caravane ou un camping-car. Il est bien sûr possible de l'adapter à tout dispositif coulissant ou autre produit en mouvement, tel un toit ouvrant ou un occulteur (store à enrouleur).The embodiment described above applies to a bay window for a vehicle sunroof. It could be a bay implemented on a side wall of a motor vehicle. It is also obvious that the invention can be applied in the same way to other structures having a wall in which a bay is defined, such as, for example, a caravan or a motorhome. It is of course possible to adapt it to any sliding device or other moving product, such as an opening roof or a blackout (roller blind).
