Description

Balai d’essuyage, dispositif d’essuyage, véhicule automobile et procédé de fabrication associéWiper blade, wiping device, motor vehicle and associated manufacturing method

La présente invention concerne le domaine des dispositifs d’essuyage de véhicules automobiles et en particulier les balais d’essuyage.The present invention relates to the field of motor vehicle wiping devices and in particular wiping blades.

Les véhicules automobiles sont couramment équipés de système d'essuie-glace pour assurer un essuyage ou balayage et un nettoyage ou lavage du pare-brise et éviter que la vision qu'a le conducteur de son environnement ne soit perturbée. Ces essuie-glaces sont classiquement entraînés par un bras effectuant un mouvement de va-et-vient angulaire et comportent des balais allongés, porteurs eux-mêmes de lames racleuses réalisées en caoutchouc. Ces lames frottent contre le pare-brise et évacuent l'eau en l'amenant en dehors du champ de vision du conducteur. Les balais sont réalisés sous la forme, soit, dans une version classique, de palonniers articulés qui tiennent la lame racleuse en plusieurs endroits discrets, soit, dans une version plus récente telle que les balais plats à vertèbre, tels que ceux dénommés FlatBlade® (pour "lame plate"), d'un ensemble semi-rigide qui maintient la lame racleuse sur toute sa longueur via une vertèbre rigide. Il existe également une troisième version dite "hybride" comprenant un carénage rigide sur lequel vient se fixer le bras d’une part et sur lequel est fixé un ensemble semi-rigide comprenant une vertèbre d’autre part. Ces balais hybrides présentent un poids supérieur aux autres versions permettant une robustesse accrue ainsi qu’une réduction des vibrations. Ces balais hybrides peuvent également permettre de ne changer que la lame racleuse lorsque cette dernière est usée.Motor vehicles are commonly equipped with windshield wiper systems to ensure wiping or sweeping and cleaning or washing of the windshield and to prevent the driver's vision of his surroundings from being disturbed. These windshield wipers are conventionally driven by an arm performing an angular back-and-forth movement and comprise elongated blades, themselves carrying scraper blades made of rubber. These blades rub against the windshield and evacuate the water by bringing it out of the driver's field of vision. The blades are made in the form of either, in a classic version, articulated levers which hold the scraper blade in several discreet places, or, in a more recent version such as flat vertebrae blades, such as those called FlatBlade® (for "flat blade"), a semi-rigid assembly which holds the scraper blade along its entire length via a rigid vertebra. There is also a third version called "hybrid" comprising a rigid fairing on which the arm is fixed on one hand and on which is fixed a semi-rigid assembly including a vertebra on the other hand. These hybrid brushes have a greater weight than the other versions allowing increased robustness as well as a reduction of vibrations. These hybrid brushes can also allow to change only the scraper blade when the latter is worn.

Par ailleurs, certains balais d’essuie-glace plats à vertèbre, par exemple de type dénommé « FlatBlade® », et notamment les balais comportant des rampes de giclage intégrées, par exemple de type dénommé « AquaBlade® », sont de plus munis d’au moins une rampe de projection de fluide de lavage ménagée dans un déflecteur (ou « spoiler » en anglais) souple, par exemple en caoutchouc, agencé le long de l’axe longitudinal de la lame d’essuyage. Un tuyau d’alimentation en fluide de lavage est agencé le long du bras et est raccordé de manière étanche à une canule d’entrée. Un tel balai permet d’obtenir d’excellentes performances de lavage. Cependant, cette solution ne peut être appliquée aux balais hybrides du fait de l’absence de déflecteur souple.Furthermore, certain flat wiper blades with a vertebra, for example of the type called "FlatBlade®", and in particular blades comprising integrated spray bars, for example of the type called "AquaBlade®", are also equipped with at least one washing fluid projection bar arranged in a flexible deflector (or "spoiler" in English), for example made of rubber, arranged along the longitudinal axis of the wiper blade. A washing fluid supply pipe is arranged along the arm and is connected in a sealed manner to an inlet nozzle. Such a blade makes it possible to obtain excellent washing performance. However, this solution cannot be applied to hybrid blades due to the absence of a flexible deflector.

Ainsi, les balais hybrides sont généralement équipés d’un dispositif de giclage embarqué dans lequel un gicleur et un tuyau d’alimentation en fluide de lavage sont portés par le bras. Une telle configuration s’appelle parfois un « Wet-arm® ».Thus, hybrid mops are generally equipped with an on-board spraying device in which a nozzle and a washing fluid supply hose are carried by the arm. Such a configuration is sometimes called a “Wet-arm®”.

Cependant, une telle solution offre une performance de lavage moins bonne que des balais comportant des rampes de giclage.However, such a solution offers poorer washing performance than brooms with spray ramps.

Il convient donc de trouver une solution permettant d’améliorer la performance de lavage associée aux balais hybrides.It is therefore necessary to find a solution to improve the washing performance associated with hybrid brooms.

A cet effet, la présente invention concerne un balai d’essuyage pour dispositif d’essuyage de véhicule automobile comprenant :
- une lame d’essuyage,
- une vertèbre s’étendant le long de la lame d’essuyage,

- un connecteur mécanique central configuré pour assurer la liaison mécanique avec un bras d’essuyage du dispositif d’essuyage,
- un connecteur hydraulique configuré pour recevoir un tuyau d’arrivée d’un liquide de nettoyage du bras d’essuyage,
- une buse de projection configurée pour être reliée hydrauliquement au connecteur hydraulique,
dans lequel la monture rigide comprend également :
- un canal hydraulique interne et longitudinal de liaison entre le connecteur hydraulique et la buse de projection,
- une pluralité d’orifices ménagés le long du canal hydraulique pour créer une rampe de pulvérisation.To this end, the present invention relates to a wiper blade for a motor vehicle wiping device comprising:

La présente invention concerne un balai d’essuyage pour dispositif d’essuyage de véhicule automobile et plus particulièrement un balai d’essuyage dit hybride tel que représenté sur les figures 1 et 2. Le balai d’essuyage 1 comprend une lame d’essuyage 9 s’étendant sur la longueur du balai d’essuyage 1. La lame d’essuyage 9 est par exemple réalisée en caoutchouc. The present invention relates to a wiper blade for a motor vehicle wiping device and more particularly a so-called hybrid wiper blade as shown in Figures 1 and 2. The wiper blade 1 comprises a wiper blade 9 extending along the length of the wiper blade 1. The wiper blade 9 is for example made of rubber.

Le balai d’essuyage 1 comprend également une monture rigide 3 de forme générale allongée. La monture rigide 3 est par exemple réalisée en matière plastique et notamment en polymère thermoplastique en particulier en polybutylène téréphtalate, dotée d’une charge renforçante de fibre de verre à 30% par poids. La monture rigide 3 comprend un connecteur mécanique central 5 configuré pour assurer la liaison mécanique avec un bras d’essuyage 6 du dispositif d’essuyage 10 (visible sur la ). Le balai d’essuyage 1 peut également comprendre un premier capot d’extrémité 7a et un deuxième capot d’extrémité 7b configurés pour venir se fixer longitudinalement de part et d’autre de la monture rigide 3 (dans le cas contraire, la monture rigide s’étend sur toute la longueur du balai d’essuyage 1). Les premier et deuxième capots d’extrémité 7a et 7b sont par exemple reliés à la monture rigide 3 via une liaison pivot dont l’axe de rotation est orienté selon une direction transversale configurée pour s’ajuster à la forme courbe de la lame d’essuyage 9. The wiper blade 1 also comprises a rigid mount 3 of generally elongated shape. The rigid mount 3 is for example made of plastic material and in particular of thermoplastic polymer, in particular polybutylene terephthalate, provided with a reinforcing filler of fiberglass at 30% by weight. The rigid mount 3 comprises a central mechanical connector 5 configured to ensure the mechanical connection with a wiping arm 6 of the wiping device 10 (visible on the ). The wiper blade 1 may also comprise a first end cap 7a and a second end cap 7b configured to be fixed longitudinally on either side of the rigid mount 3 (otherwise, the rigid mount extends over the entire length of the wiper blade 1). The first and second end caps 7a and 7b are for example connected to the rigid mount 3 via a pivot connection whose axis of rotation is oriented in a transverse direction configured to adjust to the curved shape of the wiper blade 9.

Le balai d’essuyage 1 comprend également une vertèbre 11 (mieux visible sur la ) s’étendant le long de la lame d’essuyage 9. La vertèbre est par exemple réalisée en acier. La lame d’essuyage 9 comprend par exemple un logement longitudinal dans lequel vient se positionner la vertèbre 11. Alternativement, un élément de maintien 12 peut être utilisé. L’élément de maintien comprend par exemple un premier logement tel qu’un logement traversant longitudinal configuré pour recevoir la vertèbre 11 et un deuxième logement tel qu’une rainure configurée pour recevoir la lame d’essuyage 9. L’ensemble formé par l’élément de maintien 12, la vertèbre 11 et la lame d’essuyage 9 formant un bloc d’essuyage. Le bloc d’essuyage est par ailleurs fixé sur la monture rigide 3 et/ou sur les éventuels capots d’extrémité 7a et 7b. La fixation du bloc d’essuyage est par exemple réalisée via des embouts d’extrémité 14a et 14b disposés aux extrémités du bloc d’essuyage pour assurer la fixation aux capots d’extrémité 7a et 7b. La monture rigide 3 peut également comprendre des crochets de retenue (non représentés) configurés pour recevoir et retenir le bloc d’essuyage au niveau de la monture rigide 3.The wiper blade 1 also includes a vertebra 11 (best seen on the ) extending along the wiper blade 9. The vertebra is for example made of steel. The wiper blade 9 comprises for example a longitudinal housing in which the vertebra 11 is positioned. Alternatively, a holding element 12 can be used. The holding element comprises for example a first housing such as a longitudinal through housing configured to receive the vertebra 11 and a second housing such as a groove configured to receive the wiper blade 9. The assembly formed by the holding element 12, the vertebra 11 and the wiper blade 9 forming a wiper block. The wiper block is furthermore fixed to the rigid mount 3 and/or to the possible end covers 7a and 7b. The attachment of the wiper block is for example carried out via end caps 14a and 14b arranged at the ends of the wiper block to ensure attachment to the end covers 7a and 7b. The rigid mount 3 may also comprise retaining hooks (not shown) configured to receive and retain the wiper block at the rigid mount 3.

Le balai d’essuyage 1 selon la présente invention comprend également un connecteur hydraulique 13 (visible sur les figures 3 à 5) configuré pour recevoir un tuyau 15 d’arrivée d’un liquide de nettoyage. Le tuyau 15 est par exemple disposé dans le bras d’essuyage 6 et relié à sa deuxième extrémité à un réservoir 17 de liquide de nettoyage et une pompe 19 configurée pour entrainer le liquide de nettoyage dans le tuyau 15. The wiper blade 1 according to the present invention also comprises a hydraulic connector 13 (visible in FIGS. 3 to 5) configured to receive a pipe 15 for supplying a cleaning liquid. The pipe 15 is for example arranged in the wiper arm 6 and connected at its second end to a reservoir 17 of cleaning liquid and a pump 19 configured to drive the cleaning liquid into the pipe 15.

La monture rigide 3 peut comprendre une dépression transversale 27 (visible sur les figures 4 et 5) disposée de manière adjacente au connecteur mécanique central 5. La dépression transversale 27 est configurée pour permettre le passage du tuyau 15 d’arrivée du liquide de nettoyage vers le connecteur hydraulique 13 et ainsi facilité la connexion du tuyau 15 sur le connecteur hydraulique 13 et éviter de former un coude sur le tuyau 15.The rigid mount 3 may comprise a transverse depression 27 (visible in FIGS. 4 and 5) arranged adjacent to the central mechanical connector 5. The transverse depression 27 is configured to allow the passage of the pipe 15 for the arrival of the cleaning liquid towards the hydraulic connector 13 and thus facilitate the connection of the pipe 15 to the hydraulic connector 13 and avoid forming a bend on the pipe 15.

Comme représenté sur les figures 3 à 5, le balai d’essuyage 1 comprend également au moins une buse de projection 21 du liquide de nettoyage. La ou les buse(s) de projection 21 sont disposée(s) sur la monture rigide 3. Dans l’exemple des figures 3 à 5, la monture rigide 3 comprend deux buses de projection 21 disposées d’un premier côté et d’un deuxième côté de la monture rigide 3, c’est-à-dire de part et d’autre longitudinalement du connecteur mécanique central 5. La ou les buses de projection 21 peuvent être des buses de projection multiples produisant un jet multidirectionnel. Les buses de projection multidirectionnelles sont par exemple configurées pour projeter du liquide de nettoyage dans différentes directions, par exemple sur une étendue angulaire comprise entre 80 et 160 degrés autour de la buse de projection 21.As shown in Figures 3 to 5, the wiper blade 1 also comprises at least one nozzle 21 for spraying the cleaning liquid. The spray nozzle(s) 21 are arranged on the rigid mount 3. In the example of Figures 3 to 5, the rigid mount 3 comprises two spray nozzles 21 arranged on a first side and a second side of the rigid mount 3, i.e. on either side longitudinally of the central mechanical connector 5. The spray nozzle(s) 21 may be multiple spray nozzles producing a multidirectional jet. The multidirectional spray nozzles are for example configured to spray cleaning liquid in different directions, for example over an angular range of between 80 and 160 degrees around the spray nozzle 21.

La monture rigide 3 comprend également un canal hydraulique interne 23 de liaison entre le connecteur hydraulique 13 et la ou les buses de projection 21. Deux canaux hydrauliques 23 peuvent être ménagés pour relier respectivement la première et la deuxième buse de projection 21 comme représenté sur la . Le canal hydraulique interne 23 s’étend selon une direction longitudinale. De plus, une pluralité d’orifices 25 sont ménagés le long du canal hydraulique interne 23, entre le connecteur hydraulique 13 et la ou les buses de projection 21 pour créer une rampe de pulvérisation. Les orifices 25 sont par exemple répartis régulièrement le long du canal hydraulique interne 23.The rigid mount 3 also comprises an internal hydraulic channel 23 for connection between the hydraulic connector 13 and the projection nozzle(s) 21. Two hydraulic channels 23 can be provided to connect the first and second projection nozzles 21 respectively as shown in the . The internal hydraulic channel 23 extends in a longitudinal direction. In addition, a plurality of orifices 25 are provided along the internal hydraulic channel 23, between the hydraulic connector 13 and the spray nozzle(s) 21 to create a spray ramp. The orifices 25 are for example distributed regularly along the internal hydraulic channel 23.

Dans les exemples de réalisation représentés sur les figures, les buses de projection 21 et les orifices 25 sont disposés d’un seul côté du balai d’essuyage, ici le côté haut pour permettre une pulvérisation devant le balai d’essuyage lorsque ce dernier se déplace de la position de retournement basse vers la position de retournement haute mais il est également possible de ménager des orifices de l’autre côté ou des deux côtés du balai d’essuyage 1 ou de positionner des buses projection configurées pour projeter du liquide de nettoyage de l’autre côté ou des deux côtés du balai d’essuyage 1. In the embodiments shown in the figures, the projection nozzles 21 and the orifices 25 are arranged on one side of the wiper blade only, here the high side to allow spraying in front of the wiper blade when the latter moves from the low turning position to the high turning position but it is also possible to provide orifices on the other side or on both sides of the wiper blade 1 or to position projection nozzles configured to project cleaning liquid on the other side or on both sides of the wiper blade 1.

Le canal hydraulique 23 a par exemple un diamètre compris entre 2 mm et 6 mm. La longueur du canal hydraulique 23 est par exemple comprise entre 25 mm et 100 mm. The hydraulic channel 23 has, for example, a diameter between 2 mm and 6 mm. The length of the hydraulic channel 23 is, for example, between 25 mm and 100 mm.

Le canal hydraulique 23 est par exemple réalisé par moulage.The hydraulic channel 23 is for example produced by molding.

Les orifices 25 ont par exemple un diamètre compris entre 0,2 mm et 1,5 mm et sont espacés les uns des autres d’une distance comprise entre 3 mm et 25 mm. The orifices 25 have, for example, a diameter of between 0.2 mm and 1.5 mm and are spaced from each other by a distance of between 3 mm and 25 mm.

Un tel balai d’essuyage permet d’obtenir une projection de liquide de nettoyage sur une longueur importante du balai d’essuyage ce qui permet d’obtenir un nettoyage efficace tout en limitant la consommation de liquide de nettoyage puisque le liquide de nettoyage est pulvérisé juste devant le balai d’essuyage. Such a wiper blade allows cleaning liquid to be sprayed over a significant length of the wiper blade, which allows for effective cleaning while limiting the consumption of cleaning liquid since the cleaning liquid is sprayed just in front of the wiper blade.

La présente invention concerne également un dispositif d’essuyage 10 comprenant au moins un bras d’essuyage 6, généralement deux bras d’essuyage 6 reliés à une tringlerie motorisée configurée pour déplacer les bras d’essuyage 6 dans un mouvement de va-et-vient entre un positionnement de retournement haute et une position de retournement basse. Le dispositif d’essuyage 10 comprend également un dispositif d’alimentation de liquide de projection comprenant notamment un réservoir 17, une pompe 19 et un tuyau d’alimentation 15 configuré pour être connecté à un connecteur hydraulique 13 et au moins un balai d’essuyage 1 tel que décrit précédemment et disposés respectivement sur le au moins un bras d’essuyage 6.The present invention also relates to a wiping device 10 comprising at least one wiping arm 6, generally two wiping arms 6 connected to a motorized linkage configured to move the wiping arms 6 in a back-and-forth movement between a high turning position and a low turning position. The wiping device 10 also comprises a projection liquid supply device comprising in particular a reservoir 17, a pump 19 and a supply pipe 15 configured to be connected to a hydraulic connector 13 and at least one wiping blade 1 as described previously and arranged respectively on the at least one wiping arm 6.

La présente invention concerne également un véhicule automobile comprenant un dispositif d’essuyage 10 tel que décrit précédemment.The present invention also relates to a motor vehicle comprising a wiping device 10 as described previously.

La présente invention concerne également un procédé de fabrication d’un balai d’essuyage 1 tel que décrit précédemment. The present invention also relates to a method of manufacturing a wiper blade 1 as described previously.

Le procédé de fabrication comprend une étape de moulage par injection de la monture rigide 3 dans laquelle le canal hydraulique 23 est formé et une étape de perçage, par laser, d’orifices 25 le long du canal hydraulique 23. Le canal hydraulique est par exemple formé par injection autour d’un élément tel qu’un câble ou une tige, le câble ou la tige étant ensuite retiré du moulage pour former le canal hydraulique 23. The manufacturing method comprises a step of injection molding the rigid frame 3 in which the hydraulic channel 23 is formed and a step of drilling, by laser, orifices 25 along the hydraulic channel 23. The hydraulic channel is for example formed by injection around an element such as a cable or a rod, the cable or the rod then being removed from the molding to form the hydraulic channel 23.

Selon un mode de réalisation alternatif, le procédé de fabrication comprend une étape de moulage par injection d’une première partie de la monture rigide 3, une étape de formation d’un canal hydraulique 23 interne et longitudinal de la monture rigide 3 par surmoulage d’une deuxième partie de la monture rigide 3 sur la première partie de la monture rigide 3 (de la même manière que dans le premier mode de réalisation un câble ou une tige peut être utilisé pour obtenir le canal hydraulique 23) et une étape de perçage, par laser, d’orifices 25 le long du canal hydraulique 23. According to an alternative embodiment, the manufacturing method comprises a step of injection molding a first part of the rigid mount 3, a step of forming an internal and longitudinal hydraulic channel 23 of the rigid mount 3 by overmolding a second part of the rigid mount 3 on the first part of the rigid mount 3 (in the same way as in the first embodiment a cable or a rod can be used to obtain the hydraulic channel 23) and a step of drilling, by laser, orifices 25 along the hydraulic channel 23.

Un tel procédé de fabrication permet d’obtenir de manière simple et peu coûteuse un balai d’essuyage hybride comprenant une rampe de pulvérisation.Such a manufacturing process makes it possible to obtain a hybrid wiper blade comprising a spray bar in a simple and inexpensive manner.
