EXPOSE ET AVANTAGES DE L’INVENTIONDESCRIPTION AND ADVANTAGES OF THE INVENTION
La présente invention a pour objet un balai d'essuie-glace notamment pour un véhicule automobile comprenant une lame d’essuyage et une installation de distribution de fluide, ce balai d'essuie-glace étant caractérisé en ce qu’il comprend une installation de distribution de gaz.The subject of the present invention is a wiper blade, in particular for a motor vehicle, comprising a wiper blade and a fluid distribution installation, this wiper blade being characterized in that it comprises a gas supply.
Le balai d'essuie-glace selon l’invention tel que défini ci-dessus, permet d’avoir un meilleur champ de vision et ainsi une visibilité optimale pour le conducteur et le cas échéant le passager.The wiper blade according to the invention as defined above, provides a better field of vision and thus optimum visibility for the driver and, where applicable, the passenger.
De façon particulièrement avantageuse, l’installation de distribution de gaz est prévue pour distribuer un flux ou une veine de gaz, de façon contrôlée, notamment une veine d’air, ce qui permet d’avoir un excellent champ de vision.In a particularly advantageous manner, the gas distribution installation is provided for distributing a flow or a stream of gas, in a controlled manner, in particular an air stream, which makes it possible to have an excellent field of vision.
Selon une caractéristique avantageuse simple et économique, l’installation de distribution de gaz a une extension longitudinale et elle distribue le gaz comprimé dans une direction transversale.According to a simple and economical advantageous characteristic, the gas distribution installation has a longitudinal extension and it distributes the compressed gas in a transverse direction.
Suivant une autre caractéristique avantageuse, l’installation de distribution de fluide distribue un fluide de nettoyage selon la lame d’essuyage car, de cette manière, on économise du fluide ou liquide de nettoyage.According to another advantageous characteristic, the fluid distribution installation distributes a cleaning fluid according to the wiping blade because, in this way, cleaning fluid or liquid is saved.
De manière particulièrement avantageuse, l’installation de distribution de gaz est prévue pour distribuer une impulsion de gaz. Cela permet de distribuer le gaz de manière ciblée dans les zones nécessaires.Particularly advantageously, the gas distribution installation is provided to distribute a pulse of gas. This allows the gas to be distributed in a targeted manner to the necessary areas.
Suivant une caractéristique particulièrement avantageuse, l’impulsion de gaz est émise dans une position d’essuyage définie, en particulier dans la position d’inversion car on évite ainsi les traînées.According to a particularly advantageous characteristic, the gas pulse is emitted in a defined wiping position, in particular in the inversion position, since streaks are thus avoided.
L’installation de distribution de gaz comporte un canal avec des orifices, ce qui est une solution simple et économique et ainsi avantageuse.The gas distribution installation has a channel with orifices, which is a simple and economical solution and thus advantageous.
Suivant une caractéristique particulièrement avantageuse, le canal est prévu à la fois pour le transport de liquide et le transport de gaz car ainsi un unique canal suffit.According to a particularly advantageous characteristic, the channel is provided both for the transport of liquid and the transport of gas because thus a single channel is sufficient.
Le canal est en matière plastique, ce qui est d’une solution particulièrement simple et économique et de ce fait avantageuse.The channel is made of plastic, which is a particularly simple and economical solution and therefore advantageous.
On améliore le champ de vision et de plus, le dispositif d’essuyage selon l’invention comporte avantageusement un balai d'essuie-glace avec une unité de distribution de gaz.The field of vision is improved and in addition, the wiper device according to the invention advantageously comprises a windscreen wiper blade with a gas distribution unit.
La présente invention sera décrite ci-après, de manière plus détaillée, à l’aide de modes de réalisation présentés dans les dessins annexés dans lesquelsThe present invention will be described below, in more detail, with the aid of embodiments presented in the accompanying drawings in which
DESCRIPTION DE MODES DE REALISATION DE L’INVENTIONDESCRIPTION OF EMBODIMENTS OF THE INVENTION
Le côté du balai d'essuie-glace 10 à l’opposé du moyen de fixation 14 comporte une lèvre d’essuyage 18 qui, en fonctionnement, entraîné par le bras d’essuie-glace 16, glisse sur la vitre à nettoyer et enlève son humidité. Les deux extrémités selon son extension longitudinale L, ont un capuchon d’extrémité 20 respectif qui termine le balai d'essuie-glace 10 dans le sens de son extension longitudinale L. Le même côté que celui du balai d'essuie-glace 14, selon l’extension longitudinale L, comporte un déflecteur 22 ayant une structure de déflecteur et améliorant la pression d’application de la lame d’essuyage contre la vitre lorsque le balai d'essuie-glace est soumis au flux du vent de circulation.The side of the wiper blade 10 opposite the fixing means 14 comprises a wiper lip 18 which, in operation, driven by the wiper arm 16, slides on the glass to be cleaned and removes its humidity. The two ends according to its longitudinal extension L, have a respective end cap 20 which terminates the wiper blade 10 in the direction of its longitudinal extension L. The same side as that of the wiper blade 14, along the longitudinal extension L, comprises a deflector 22 having a deflector structure and improving the application pressure of the wiper blade against the window when the wiper blade is subjected to the flow of the circulating wind.
La
Le canal 28 peut également recevoir du liquide de nettoyage. Lorsque le liquide est comprimé, il traverse l’orifice 30 et mouille la vitre à essuyer. Ainsi, le canal 28 le ou les orifices 30 forment une installation de distribution de fluide 34. Le canal 28 peut recevoir, par exemple, en alternance, du gaz et du liquide ou fluide de nettoyage.Channel 28 can also receive cleaning liquid. When the liquid is compressed, it passes through orifice 30 and wets the window to be wiped. Thus, the channel 28 or the orifices 30 form a fluid distribution installation 34. The channel 28 can receive, for example, alternately, gas and liquid or cleaning fluid.
La
En variante ou en complément, à la place d’un bref jet de gaz, on peut également distribuer du gaz pratiquement pendant tout le mouvement descendant pour avoir ainsi une veine d’air contrôlée pratiquement pendant tout le mouvement descendant du balai d'essuie-glace 10.Alternatively or additionally, instead of a brief gas jet, gas can also be supplied practically throughout the downward movement to thus have a controlled air stream practically during the entire downward movement of the wiper blade. ice cream 10.
Une brève impulsion de gaz signifie que le gaz est distribué au début du mouvement descendant ou déjà juste avant le début du mouvement descendant dans une plage angulaire 40 allant jusqu’à 10° et en particulier allant jusqu’à 5°.A short gas pulse means that the gas is dispensed at the start of the downward movement or already just before the start of the downward movement in an angular range 40 of up to 10° and in particular up to 5°.
La
Le canal 28 est réalisé en une seule pièce avec la lame déflectrice 22 en matière plastique, notamment en EPDM, par un procédé d’extrusion. Pour cela, on peut utiliser un procédé d’extrusion à plusieurs composants selon lequel on combine différentes matières plastiques. En particulier, le canal 28 peut se réaliser en une autre matière plastique que le restant de la lame déflectrice 22. Les orifices 30 sont percés dans le canal 28 à l’aide d’un faisceau laser ; ces orifices sont d’un diamètre inférieur à 1 mm, notamment un diamètre de l’ordre de 0,4 mm.The channel 28 is made in one piece with the deflector blade 22 made of plastic material, in particular EPDM, by an extrusion process. For this, a multi-component extrusion process can be used in which different plastic materials are combined. In particular, the channel 28 can be made of another plastic material than the rest of the deflector blade 22. The orifices 30 are drilled in the channel 28 using a laser beam; these orifices have a diameter of less than 1 mm, in particular a diameter of the order of 0.4 mm.
En variante, l’invention peut prévoir deux canaux 28 parallèles. Le canal 28 qui est, chaque fois à l’avant ou en amont selon le sens d’essuyage reçoit le liquide de nettoyage et le canal arrière ou aval 28 selon le sens d’essuyage reçoit le gaz. Comme décrit ci-dessus, on peut prévoir soit une brève impulsion de gaz, soit également une distribution de gaz sur une plus grande plage de déplacement du balai d'essuie-glace 10.Alternatively, the invention may provide two parallel channels 28. The channel 28 which is, each time at the front or upstream depending on the wiping direction, receives the cleaning liquid and the rear or downstream channel 28 depending on the wiping direction receives the gas. As described above, either a short gas pulse or also a gas distribution over a greater range of movement of the wiper blade 10 can be provided.
L’installation de soupape 64 est, par exemple, sous la forme d’une électrovanne. Toutefois, on peut avoir également des solutions mécaniques, à savoir une liaison mécanique entre l’unité d’entraînement 52 et l’installation de soupape 64. L’installation générant le gaz 60 est, par exemple, une simple pompe à air comprimé qui aspire l’air ambiant et le met sous pression dans la conduite de pression de gaz 62. L’installation générant le gaz 60 peut également être combinée en complément à un réservoir qui stocke de l’air comprimé. En variante, on peut également prévoir un système à cartouche utilisant des cartouches de gaz, en particulier, si l’on veut utiliser un gaz autre que l’air. En outre et en complément, l’installation générant le gaz 60 est équipée d’une installation de chauffage qui chauffe le gaz avec l’air comprimé. Ainsi, le gaz qui est, par exemple, de l’azote ou de l’hélium est utilisé en parallèle avec l’air. En principe, on peut toutefois utiliser n’importe quel gaz ou mélange de gaz.The valve installation 64 is, for example, in the form of a solenoid valve. However, it is also possible to have mechanical solutions, namely a mechanical connection between the drive unit 52 and the valve installation 64. The installation generating the gas 60 is, for example, a simple compressed air pump which draws in the ambient air and puts it under pressure in the gas pressure line 62. The installation generating the gas 60 can also be combined in addition to a reservoir which stores compressed air. As a variant, it is also possible to provide a cartridge system using gas cartridges, in particular, if it is desired to use a gas other than air. In addition and in addition, the installation generating gas 60 is equipped with a heating installation which heats the gas with compressed air. Thus, the gas which is, for example, nitrogen or helium is used in parallel with the air. In principle, however, any gas or mixture of gases can be used.
L’unité de nettoyage 56 comprend un réservoir avec du liquide de nettoyage, par exemple, de l’eau additionnée d’un agent de nettoyage tel qu’un tensio-actif. En outre, l’unité de nettoyage 56 comprend une pompe qui met en pression le liquide de nettoyage pour alimenter la conduite de nettoyage 58.The cleaning unit 56 comprises a reservoir with cleaning liquid, for example, water with the addition of a cleaning agent such as a surfactant. In addition, the cleaning unit 56 includes a pump which pressurizes the cleaning liquid to feed the cleaning line 58.
