Abstract
Description
"BALAI D 'ESSUIE-GLACE COMPRENANT UN GICLEUR DE LIQUIDE DE NETTOYAGE ET UNE GOUTTIERE DE GUIDAGE DU LIQUIDE DE NETTOYAGE". La présente invention concerne le système de nettoyage du pare-brise ou de la lunette arrière d'un véhicule, notamment automobile. "WIPER BLADE INCLUDING A CLEANING FLUID JET AND A CLEANING LIQUID GUIDE GUTTER". The present invention relates to the cleaning system of the windshield or the rear window of a vehicle, especially automobile.
De façon classique, le nettoyage du pare-brise ou de la lunette arrière du véhicule est assuré par un gicleur situé généralement, pour le nettoyage du pare- brise, sur le capot du véhicule, ou pour le nettoyage de la lunette arrière, en périphérie de cette lunette. Ce gicleur projette sur la vitre à nettoyer un produit de lavage qui est ensuite raclé par les essuie-glaces du véhicule. Conventionally, the cleaning of the windshield or the rear window of the vehicle is provided by a nozzle generally located, for cleaning the windshield, on the hood of the vehicle, or for cleaning the rear window, peripherally of this telescope. This nozzle projects on the glass to clean a detergent which is then scraped by the wipers of the vehicle.
Ces gicleurs projettent généralement le liquide de nettoyage suivant une répartition inégale sur la totalité de la surface de la vitre à nettoyer, et sur la carrosserie entourant cette vitre. Les balais d'essuie- glace ne raclant qu'une partie de la vitre, les zones non raclées de la vitre et la carrosserie sont salies par le liquide de nettoyage. These nozzles generally project the cleaning liquid in an uneven distribution over the entire surface of the window to be cleaned, and on the bodywork surrounding this window. The wiper blades scrape only a portion of the glass, the unslotted areas of the glass and the body are dirty with the cleaning fluid.
Par ailleurs, les gicleurs situés sur le capot du véhicule sont inesthétiques et nuisent aux performances aérodynamiques du véhicule. La conception de ces gicleurs et leur mise au point, pour assurer la meilleure répartition possible du liquide de nettoyage sur la vitre, représentent une charge de travail importante lors de la conception du véhicule, devant être renouvelée pour chaque modèle de véhicule. Enfin, chaque gicleur présentant ses propres caractéristiques d'orientation et d'angle de dispersion, la fabrication d'une gamme de véhicules nécessite la gestion de plusieurs références différentes de gicleurs. In addition, the nozzles located on the hood of the vehicle are unsightly and affect the aerodynamic performance of the vehicle. The design of these sprinklers and their development, to ensure the best possible distribution of cleaning fluid on the glass, represent a significant workload during the design of the vehicle, to be renewed for each model of vehicle. Finally, each nozzle having its own characteristics of orientation and dispersion angle, the manufacture of a range of vehicles requires the management of several different references sprinklers.
Pour pallier à ces inconvénients, il a été proposé, notamment par le document FR 2 695 606, de réaliser la distribution de liquide de nettoyage au niveau des essuie-glaces eux-mêmes, en différents points situés à proximité des balais. Cette solution permet de ne verser le liquide de nettoyage que sur la zone de la vitre qui sera raclée par le balai, ce qui permet d'économiser du liquide de nettoyage et d'éviter de salir les zones de la vitre non balayées par les essuie-glaces et la carrosserie environnante. To overcome these drawbacks, it has been proposed, in particular by the document FR 2 695 606, to carry out the distribution of cleaning liquid at the level of windscreen wipers themselves at different points near the brooms. This solution allows to pour the cleaning liquid on the area of the glass that will be scraped by the broom, which saves cleaning fluid and avoid dirtying the areas of the glass not swept by the wiper -glaces and the surrounding bodywork.
De tels balais d ' essuie-glace, présentant sur toute leur longueur une conduite interne destinée à conduire le liquide de nettoyage vers les différents points de distribution, sont cependant difficiles à réaliser, et donc coûteux. L'utilisation d'un tel système de distribution du liquide de nettoyage entraîne donc une augmentation du coût de fabrication du véhicule, et des dépenses importantes pour l'utilisateur du véhicule quand il doit changer ses balais d ' essuie-glace . Such wiper blades, having along their entire length an inner pipe for conducting the cleaning fluid to the various distribution points, however, are difficult to achieve, and therefore expensive. The use of such a cleaning liquid dispensing system therefore leads to an increase in the cost of manufacturing the vehicle, and significant expenses for the user of the vehicle when he has to change his wiper blades.
La présente invention a pour objectif de pallier ces inconvénients de l'art antérieur. Plus précisément, la présente invention a pour objectif de fournir un balai d ' essuie-glace permettant d'assurer la distribution et la répartition précise du liquide de nettoyage sur la zone de la vitre qui est balayée par l'essuie-glace, qui soit particulièrement facile et peu coûteux à fabriquer. Un autre objectif de l'invention est de fournir un tel balai d ' essuie-glace qui permette d'éviter les pertes de liquide de nettoyage. The present invention aims to overcome these disadvantages of the prior art. More specifically, the present invention aims to provide a wiper blade to ensure the distribution and the precise distribution of the cleaning fluid on the area of the window which is swept by the wiper, which is particularly easy and inexpensive to manufacture. Another object of the invention is to provide such a windscreen wiper blade which makes it possible to avoid losses of cleaning fluid.
Ces objectifs, ainsi que d'autres qui apparaîtront plus clairement par la suite, sont atteints à l'aide d'un balai d ' essuie-glace de véhicule, notamment automobile, comprenant un support longitudinal le long duquel est fixée une raclette d'essuyage destinée à être en contact avec une vitre, le balai comportant une gouttière inversée s 'étendant sensiblement parallèlement à la raclette d'essuyage, et présentant une ouverture longitudinale destinée à être en regard de la vitre, le balai d ' essuie-glace comportant un gicleur fixé à proximité de l'une des extrémités de la gouttière, apte à projeter un liquide de nettoyage dans la gouttière sensiblement dans la direction longitudinale de celle-ci. These objectives, as well as others that will appear more clearly later, are achieved with the aid of a vehicle windshield wiper blade, particularly a motor vehicle, comprising a longitudinal support along which is fixed a squeegee of wiping intended to be in contact with a window, the broom including an inverted channel extending substantially parallel to the wiper blade, and having a longitudinal opening intended to be opposite the window, the wiper blade comprising a nozzle fixed near one end of the gutter, suitable for projecting a cleaning liquid in the gutter substantially in the longitudinal direction thereof.
Avantageusement, ledit gicleur est apte à projeter ledit liquide de nettoyage sous forme de jet laminaire. Advantageously, said nozzle is capable of projecting said cleaning liquid in the form of a laminar jet.
Selon un mode de réalisation possible de l'invention, la raclette d'essuyage est formée par un profilé souple, lié audit support longitudinal, ladite gouttière inversée étant formée dans ledit profilé souple . According to a possible embodiment of the invention, the wiper blade is formed by a flexible section, connected to said longitudinal support, said inverted channel being formed in said flexible section.
Selon un autre mode de réalisation possible de l'invention, la gouttière présente une section transversale en forme de U, dont l'une des branches est assemblée au support longitudinal et l'autre branche est libre, l'ouverture du U étant destinée à être en regard de la vitre. According to another possible embodiment of the invention, the channel has a U-shaped cross section, one of the branches is assembled to the longitudinal support and the other branch is free, the opening of the U being intended for to be facing the window.
Avantageusement, le gicleur est fixé à proximité de l'extrémité de la gouttière destinée à être la plus proche de l'axe de rotation de l'essuie-glace. Advantageously, the nozzle is fixed near the end of the gutter intended to be closest to the axis of rotation of the wiper.
Avantageusement, l'extrémité de la gouttière opposée à celle à proximité de laquelle est fixé le gicleur est fermée. Advantageously, the end of the gutter opposite to that near which is fixed the nozzle is closed.
Avantageusement, le balai d ' essuie-glace est galbé longitudinalement pour épouser la forme galbée de la vitre, la gouttière présente un gable correspondant au galbe de la raclette. Advantageously, the wiper blade is curved longitudinally to fit the curved shape of the window, the gutter has a gable corresponding to the curve of the squeegee.
Avantageusement, le gicleur est porté par un embout de distribution et alimenté en liquide de nettoyage par une tubulure de raccordement de cet embout de distribution, destinée à être connectée à un tuyau souple d'alimentation en liquide de nettoyage. Advantageously, the nozzle is carried by a dispensing nozzle and supplied with cleaning liquid by a connecting pipe of this dispensing nozzle, intended to be connected to a hose for supplying cleaning liquid.
L'invention concerne également un essuie-glace de véhicule comportant un balai tel que décrit ci-dessus, et un véhicule automobile comprenant un tel essuie-glace. The invention also relates to a vehicle wiper comprising a wiper as described above, and a motor vehicle comprising such a wiper.
D'autres caractéristiques et avantages de l'invention apparaîtront plus clairement à la lecture de la description qui suit d'un mode de réalisation illustratif et non limitatif, accompagné de dessins parmi lesquels : Other features and advantages of the invention will emerge more clearly on reading the following description of an embodiment. illustrative and non-limiting, accompanied by drawings among which:
- la figure 1 représente un balai d ' essuie-glace selon un mode de réalisation de l'invention ; - Figure 1 shows a wiper blade according to one embodiment of the invention;
- la figure 2 représente une partie d'un essuie- glace mettant en œuvre le balai de la figure 1. FIG. 2 represents a portion of a windscreen wiper implementing the blade of FIG. 1.
Les figures 1 et 2 montrent un balai d ' essuie-glace Figures 1 and 2 show a wiper blade
1 qui, comme le montre la figure 2, est destiné à être fixé à l'extrémité d'un levier d ' essuie-glace 2. Lors de l'utilisation de l'essuie-glace, le levier d ' essuie-glace1 which, as shown in Figure 2, is intended to be attached to the end of a windshield wiper lever 2. When using the windshield wiper, the windshield wiper lever
2 pivote autour d'un axe d ' essuie-glace non représenté, en entraînant le balai 1 contre la vitre à essuyer. 2 rotates about a wiper axis not shown, by driving the broom 1 against the window to be wiped.
Le balai d ' essuie-glace 1 présente une forme longitudinale galbée pour s'adapter au galbe de la vitre devant être nettoyée. Il comporte un support longitudinal 10 portant sur toute sa longueur une raclette d'essuyage 12 en matériau déformable élastiquement , qui est destinée à être en contact avec la vitre. The wiper blade 1 has a curved longitudinal shape to fit the curve of the window to be cleaned. It comprises a longitudinal support 10 over its entire length a wiper blade 12 of elastically deformable material, which is intended to be in contact with the window.
Le balai d ' essuie-glace 1 porte un embout de distribution de liquide de nettoyage sur la vitre, qui comporte un gicleur 32. L'embout de distribution 3 qui est fixé à l'extrémité du balai 1 la plus proche de l'axe de rotation de l'essuie-glace. Le gicleur 3 reçoit le fluide de nettoyage par une tubulure de raccordement 31 de l'embout 3, à laquelle est connecté un tuyau souple d'arrivée de fluide, et rejette ce fluide en formant un jet laminaire de fluide sensiblement dans la direction longitudinale du balai d ' essuie-glace 1 vers son extrémité la plus éloignée de l'axe de rotation de l'essuie-glace. The wiper blade 1 carries a nozzle for dispensing cleaning liquid on the window, which has a nozzle 32. The dispensing nozzle 3 which is fixed to the end of the blade 1 closest to the axis rotation of the wiper. The nozzle 3 receives the cleaning fluid through a connecting pipe 31 of the nozzle 3, to which is connected a flexible fluid inlet pipe, and rejects this fluid forming a laminar fluid jet substantially in the longitudinal direction of the fluid. wiper blade 1 towards its end farthest from the axis of rotation of the wiper.
Le balai d ' essuie-glace 1 présente également, sur la plus grande partie de sa longueur, une gouttière inversée 13 présentant une section transversale en forme de U. L'un des bords de la gouttière 13, correspondant à l'une des branches du U, étant fixé au support longitudinal 10 sur toute sa longueur, tandis que l'autre bord de la gouttière 13, correspondant à l'autre branche du U, est libre et s'étend sensiblement parallèlement à la raclette d'essuyage 12. Ces deux bords de la gouttière 13 définissent une ouverture longitudinale de la gouttière 13, dans la direction destinée à être en regard avec la vitre. The wiper blade 1 also has, over most of its length, an inverted channel 13 having a U-shaped cross section. One of the edges of the gutter 13, corresponding to one of the branches U, being fixed to the longitudinal support 10 over its entire length, while the other edge of the gutter 13, corresponding to the other branch U, is free and extends substantially parallel to the wiper blade 12. These two edges of the channel 13 define a longitudinal opening of the channel 13, in the direction intended to be facing the window.
La gouttière inversée 13 est également ouverte à son extrémité située au niveau de l'extrémité du balai 1 destiné à être la plus proche de l'axe de rotation de l'essuie-glace 2, et est placée de telle sorte que le gicleur 32 de l'embout de distribution 3 projette le liquide dans la gouttière 13 par cette extrémité ouverte. The inverted channel 13 is also open at its end located at the end of the blade 1 intended to be closest to the axis of rotation of the wiper 2, and is placed so that the nozzle 32 of the dispensing nozzle 3 projects the liquid in the channel 13 by this open end.
Le jet de liquide de nettoyage ainsi projeté, sous forme de jet laminaire, sensiblement dans la direction longitudinale du balai 1, est protégé des perturbations aérodynamiques par la gouttière 13. Par ailleurs, cette gouttière 13 présentant une forme galbée suivant la forme galbée du balai 1, elle guide le jet laminaire de liquide projeté par le gicleur 32 afin qu'il suive la forme du balai 1. The jet of cleaning liquid thus projected, in the form of a laminar jet, substantially in the longitudinal direction of the blade 1, is protected from aerodynamic disturbances by the gutter 13. Furthermore, this gutter 13 having a curved shape according to the curved shape of the blade 1, it guides the laminar jet of liquid projected by the nozzle 32 so that it follows the shape of the blade 1.
La projection de liquide de nettoyage se faisant pendant le mouvement des essuie-glaces, la force centrifuge due à ce mouvement contribue à guider le liquide de nettoyage jusqu'à l'extrémité du balai la plus éloignée de l'axe de rotation de l'essuie-glace 2. The projection of cleaning liquid being done during the movement of the wipers, the centrifugal force due to this movement helps to guide the cleaning fluid to the end of the wiper furthest from the axis of rotation of the wiper. wiper 2.
Tout le long de la gouttière 13, une partie du liquide de nettoyage se répand par gravité vers la raclette 12 et la vitre devant cette raclette 12. La puissance du jet généré par le gicleur 32 est avantageusement choisie pour que la totalité du liquide projeté s'écoule ainsi par gravité de façon régulière sur toute la longueur de la gouttière 13. Throughout the gutter 13, a portion of the cleaning liquid is spread by gravity to the squeegee 12 and the window in front of the squeegee 12. The power of the jet generated by the nozzle 32 is preferably chosen so that all the liquid sprayed s thus flows by gravity evenly over the entire length of the gutter 13.
A l'extrémité du balai la plus éloignée de l'axe de rotation de l'essuie-glace 2, la gouttière 13 est fermée, comme représenté sur la figure 1, pour permettre à l'excès de liquide de nettoyage de tomber par gravité devant la raclette pour éviter l'écoulement de l'excès de liquide à l'extrémité du balai 1. Selon un autre mode de réalisation possible, non représenté, la gouttière 13 peut également être ouverte à ses deux extrémités. At the end of the wiper farthest from the axis of rotation of the wiper 2, the gutter 13 is closed, as shown in Figure 1, to allow the excess cleaning liquid to fall by gravity in front of the squeegee to prevent the flow of excess liquid at the end of the blade 1. According to another embodiment of possible embodiment, not shown, the channel 13 may also be open at both ends.
Il est à noter que, selon une variante possible de l'invention non représentée par les figures, la gouttière inversée peut être intégrée au profilé souple formant la raclette. Elle s'étend dans ce cas sensiblement parallèlement à la lame d'essuyage de cette raclette. It should be noted that, according to a possible variant of the invention not shown in the figures, the inverted channel can be integrated with the flexible profile forming the squeegee. It extends in this case substantially parallel to the wiper blade of the squeegee.
La mise en œuvre de l'invention apporte de nombreux avantages par rapport aux solutions de l'art antérieur. Elle permet ainsi d'utiliser, pour tous les modèles de véhicule, un gicleur identique, qui n'a pas à présenter une inclinaison ou un angle de vaporisation particulier pour chaque modèle de véhicule. En effet, le gicleur utilisé doit uniquement projeter un jet, sensiblement dans la direction longitudinale du balai. Ce gicleur étant mobile avec le balai d'essuie-glace, et situé en hauteur par rapport à la vitre, il présente moins de risques d'obstruction dus à la gravité que les gicleurs fixes de l'art antérieur. The implementation of the invention provides many advantages over the solutions of the prior art. It thus makes it possible to use, for all vehicle models, an identical nozzle, which does not have to have a particular inclination or spray angle for each model of vehicle. Indeed, the nozzle used must only project a jet, substantially in the longitudinal direction of the blade. This nozzle being movable with the wiper blade, and located in height relative to the window, it presents less risk of obstruction due to gravity than the fixed nozzles of the prior art.
Le même embout de distribution de liquide de nettoyage pouvant être utilisé pour toutes les longueurs de raclette, et donc pour tous les véhicules, la solution de l'invention permet de diminuer le nombre de pièces utilisées pour la fabrication d'une gamme de véhicules, ce qui permet de diminuer ses coûts de production et de simplifier la logistique. The same cleaning fluid dispensing nozzle that can be used for all wiper lengths, and therefore for all vehicles, the solution of the invention makes it possible to reduce the number of parts used for the manufacture of a range of vehicles, which reduces production costs and simplifies logistics.
Enfin, la même solution technique pouvant être mise en œuvre sans difficulté sur tout type de véhicules en utilisant des embouts de distribution identiques, la conception du système de nettoyage de vitre pour chaque véhicule est simplifiée, et la mise au point ne nécessite pas de réglages, et peu de validations et d'expérimentation en soufflerie. Finally, the same technical solution can be implemented without difficulty on any type of vehicle using identical dispensing nozzles, the design of the glass cleaning system for each vehicle is simplified, and the development does not require adjustments. , and few validations and experiments in the wind tunnel.
La solution selon l'invention permettant de ne projeter du liquide de nettoyage que sur la surface qui va être essuyée par les balais d'essuie-glace, elle permet également un lavage sobre et efficace, une économie importante de produits de lavage et une bonne efficacité en dynamique. The solution according to the invention for not projecting cleaning liquid on the surface that will be wiped by the wiper blades, it also allows a sober and efficient washing, a significant saving of washing products and a good efficiency in dynamics.
Enfin, cette solution permet également de supprimer les gicleurs placés sur le capot des véhicules, ce qui améliore l'esthétique et l'aérodynamique des véhicules et simplifie leur conception. Finally, this solution also eliminates sprinklers placed on the bonnet of vehicles, which improves the aesthetics and aerodynamics of vehicles and simplifies their design.
