Description

Dispositif d'insonorisation et d'étanchéité d'une conduite d'air, notamment dans une installation de ventilation, chauffage et/ou climatisation de véhicule automobileSoundproofing and sealing device for an air pipe, in particular in a ventilation, heating and / or air conditioning installation of a motor vehicle
L'invention concerne le domaine des dispositifs comportant une partie pour l'insonorisation et une partie pour l'étan- chéité de conduites d'air, notamment dans des installations de ventilation, chauffage et/ou climatisation de véhicule automobile .The invention relates to the field of devices comprising a part for soundproofing and a part for sealing air ducts, in particular in ventilation, heating and / or air conditioning installations of motor vehicles.
L'invention concerne en particulier un dispositif comprenant une partie d'étanchéité reposant sur une paroi sommitale de la conduite d'air, et une partie d'insonorisation entourant ses parois latérales externes. La partie d'insonorisation est habituellement un joint comportant une ouverture annulaire et loge partiellement un joint d'étanchéité le long de sa périphérie radialement interne.The invention relates in particular to a device comprising a sealing part resting on a top wall of the air duct, and a soundproofing part surrounding its external side walls. The soundproofing part is usually a seal having an annular opening and partially houses a seal along its radially inner periphery.
Un dispositif du type précité peut être monté, par exemple, sur la conduite d'air de ventilation, située dans l'habitacle d'un véhicule automobile. Généralement, le joint d'insono- risation entoure les parois latérales externes de la conduite d'air. Une partie supérieure du joint fait saillie au dessus de la paroi sommitale de la conduite, laquelle forme alors, avec cette partie supérieure, une nervure sur la périphérie interne du joint. Le joint d'étanchéité est ensuite monté par collage sur cette nervure, en contact avec la paroi sommitale de la conduite et la périphérie interne de la partie supérieure du joint d'insonorisation.A device of the aforementioned type can be mounted, for example, on the ventilation air duct, located in the passenger compartment of a motor vehicle. Typically, the sound seal surrounds the outer side walls of the air line. An upper part of the joint protrudes above the top wall of the pipe, which then forms, with this upper part, a rib on the internal periphery of the joint. The seal is then mounted by gluing on this rib, in contact with the top wall of the pipe and the internal periphery of the upper part of the soundproofing seal.
Cependant, cette configuration connue a notamment pour inconvénient de posséder une structure complexe qui nuit à une fabrication en grande série sur des chaînes de montage automatisées. En effet, elle nécessite la réalisation d'au moins deux opérations de moulage indépendantes, l'une pour le joint d'insonorisation, généralement en polyuréthanne, et l'autre pour le joint d'étanchéité, généralement en polychlo- rure de vinyle. Ensuite, il faut procéder à l'assemblage des joints d'étanchéité et d'insonorisation.However, this known configuration has the drawback in particular of having a complex structure which is detrimental to mass production on automated assembly lines. Indeed, it requires the realization of at least two independent molding operations, one for the soundproofing joint, generally made of polyurethane, and the other for the sealing joint, generally made of polychloride. vinyl rure. Then you have to assemble the seals and soundproofing.
L'invention a notamment pour but de simplifier la structure des dispositifs de la technique antérieure.The object of the invention is in particular to simplify the structure of the devices of the prior art.
Elle propose à cet effet un dispositif du type précité, mais dans lequel les deux parties d'insonorisation et d'étanchéité sont réalisées d'une seule pièce. Ainsi, on forme, selon l'invention, un unique élément assurant à la fois les deux fonctions d'insonorisation et d'étanchéité de la conduite d'air.To this end, it proposes a device of the aforementioned type, but in which the two parts for soundproofing and sealing are made in one piece. Thus, according to the invention, a single element is formed which provides both the soundproofing and sealing functions of the air duct.
Avantageusement, le dispositif comporte des moyens de fixation à la conduite d'air. Ces moyens sont réalisés sous la forme d'un ensemble de blocs faisant saillie radialement vers l'intérieur ou vers l'extérieur du joint d'insonorisation, sensiblement parallélépipédiques. Ils sont alors destinés à être introduits dans des logements sensiblement homologues que portent des parois latérales de la conduite d'air.Advantageously, the device comprises means for fixing to the air duct. These means are produced in the form of a set of blocks projecting radially inwards or outwards from the soundproofing joint, which are substantially parallelepiped. They are then intended to be introduced into substantially homologous housings which are carried on the side walls of the air duct.
Ainsi le dispositif selon l'invention est réalisé sous la forme d'une pièce monobloc comportant une partie latérale faisant office de joint d'insonorisation, une partie supérieure faisant office de joint d'étanchéité et une partie inférieure portant les moyens de fixation.Thus, the device according to the invention is produced in the form of a single piece comprising a lateral part acting as a soundproofing joint, an upper part acting as a sealing joint and a lower part carrying the fixing means.
Avantageusement, pour réaliser le dispositif selon l'inven- tion, on prévoit seulement une première étape de moulage d'une mousse de polyuréthanne à pores fermés, par réticula- tion, et une seconde étape de reprise de moulage pour former les blocs dans le même matériau.Advantageously, in order to produce the device according to the invention, only a first step of molding a closed-pore polyurethane foam is provided, by crosslinking, and a second step of resuming molding to form the blocks in the same material.
D'autres caractéristiques et avantages de l'invention apparaîtront à l'examen de la description détaillée ci-après, et des dessins annexés sur lesquels : - la figure 1 est une vue en perspective du dispositif selon l'invention, monté sur une conduite d'aération dans l'exemple décrit, notamment d'une installation de ventilation, chauffage et/ou climatisation,Other characteristics and advantages of the invention will appear on examining the detailed description below, and the appended drawings in which: FIG. 1 is a perspective view of the device according to the invention, mounted on an aeration pipe in the example described, in particular of a ventilation, heating and / or air conditioning installation,
- la figure 2 est une vue en perspective de la partie d'insonorisation seulement du dispositif, etFIG. 2 is a perspective view of the soundproofing part only of the device, and
- la figure 3 est une vue partielle en coupe de la conduite d'air et du dispositif selon l'invention, représentant en particulier et de manière simplifiée, les moyens de fixation du dispositif.- Figure 3 is a partial sectional view of the air duct and the device according to the invention, showing in particular and in a simplified manner, the means for fixing the device.
On se réfère tout d'abord à la figure 1 qui représente le dispositif selon l'invention, monté sur une conduite d'air d'une installation de ventilation, chauffage et/ou climatisation, et assurant les deux fonctions d'insonorisation et d'étanchéité de la conduite d'air. Dans l'exemple décrit, la conduite d'air représentée 1 est logée en partie dans la planche de bord (non représentée) de l'habitacle d'un véhicule automobile. Elle forme l'extrémité d'une conduite (non représenté) destiné à acheminer de l'air ventilé par l'installation de ventilation, chauffage et/ou climatisation du véhicule, au sein de l'habitacle.Firstly, reference is made to FIG. 1 which represents the device according to the invention, mounted on an air duct of a ventilation, heating and / or air conditioning installation, and ensuring the two functions of soundproofing and of air line tightness. In the example described, the air line shown 1 is partially housed in the dashboard (not shown) of the passenger compartment of a motor vehicle. It forms the end of a pipe (not shown) intended to convey ventilated air by the ventilation, heating and / or air conditioning system of the vehicle, within the passenger compartment.
Le dispositif selon 1 ' invention comporte une partie faisant fonction de joint d'insonorisation 2 de forme sensiblement annulaire. Elle entoure les parois latérales de la conduite d'air 1. D'une part, sa partie inférieure est en contact avec une paroi sommitale 4 faisant saillie de la conduite 1, d'autre part, sa périphérie radialement interne 5 est en contact avec les parois latérales externes 10 (figure 3) de la conduite 1. La figure 1 fait apparaître alors que la forme générale du dispositif s'inscrit sensiblement dans un parallélogramme pour épouser la forme de la conduite 1.The device according to the invention comprises a part acting as a soundproofing joint 2 of substantially annular shape. It surrounds the side walls of the air duct 1. On the one hand, its lower part is in contact with a top wall 4 projecting from the duct 1, on the other hand, its radially internal periphery 5 is in contact with the external lateral walls 10 (FIG. 3) of the pipe 1. FIG. 1 shows that the general shape of the device is substantially in a parallelogram to match the shape of the pipe 1.
La partie 3 du dispositif d'insonorisation et d'étanchéité assure la fonction de joint d'étanchéité. Elle est en contact avec une paroi sommitale 9 (figure 3) de la conduite d'air 1. Selon l'invention, elle est réalisée d'une seule pièce avec la partie inférieure d'insonorisation 2 du dispositif. Les joints d'étanchéité de la technique antérieure à la présente invention étaient montés par collage à l'emplacement 11 (figure 3) représenté en traits tiretés sur la figure 1. La partie d'étanchéité 3 comporte une ouverture annulaire, laquelle est sensiblement coaxiale avec la conduite 1.Part 3 of the soundproofing and sealing device acts as a seal. It is in contact with a top wall 9 (FIG. 3) of the air duct 1. According to the invention, it is made in one piece with the lower soundproofing part 2 of the device. The seals of the technique prior to the present invention were mounted by gluing at location 11 (Figure 3) shown in dashed lines in Figure 1. The sealing part 3 has an annular opening, which is substantially coaxial with driving 1.
Avantageusement, la structure du boîtier 1 formant la conduite d'air et la partie inférieure 2 du dispositif restent inchangées.Advantageously, the structure of the housing 1 forming the air duct and the lower part 2 of the device remain unchanged.
La figure 2 représente la partie d'insonorisation 2 du dispositif. La structure de cette partie n'est guère modifiée par la présente invention. La partie supérieure 3 assurant l'étanchéité de la conduite 1 est solidaire, d'une pièce monobloc selon la présente invention, avec la partie inférieure d'insonorisation 2. La partie 3 se raccorde près de la surface sommitale 7, sur l'emplacement 11 de la partie d'insonorisation 2, et repose sur la paroi sommitale 9 ( figure 3 ) de la conduite 1. La périphérie interne 5 de la partie d'insonorisation 2 entoure les parois externes 10 de la conduite d'air (figure 3).Figure 2 shows the soundproofing part 2 of the device. The structure of this part is hardly modified by the present invention. The upper part 3 sealing the pipe 1 is integral with a one-piece piece according to the present invention, with the lower soundproofing part 2. The part 3 is connected near the top surface 7, at the location 11 of the soundproofing part 2, and rests on the top wall 9 (FIG. 3) of the pipe 1. The internal periphery 5 of the soundproofing part 2 surrounds the external walls 10 of the air duct (FIG. 3 ).
La figure 2 fait apparaître des blocs 6a de forme sensiblement parallélépipédique faisant saillie de l'intérieur des parois latérales 5 de la partie d'insonorisation 2. Ces blocs 6a sont disposés sous la zone de contact avec la partie supérieure 3 assurant l'étanchéité de la conduite d'air. Ils sont destinés à être introduits dans des logements sensiblement homologues que comprennent les parois latérales de la conduite 1 (figure 3). La partie d'insonorisation 2 comporte par ailleurs un panneau de fond 8, lequel porte encore deux blocs 6b faisant saillie vers l'extérieur du panneau 8. Ces deux blocs 6b sont logés dans des fentes sensiblement homologues de la conduite 1.FIG. 2 shows blocks 6a of substantially parallelepiped shape projecting from the inside of the side walls 5 of the soundproofing part 2. These blocks 6a are arranged under the zone of contact with the upper part 3 ensuring the sealing of the air line. They are intended to be introduced into substantially homologous housings which comprise the lateral walls of the pipe 1 (FIG. 3). The soundproofing part 2 also comprises a bottom panel 8, which further carries two blocks 6b projecting towards the outside of the panel 8. These two blocks 6b are housed in slots which are substantially homologous to the pipe 1.
Le dispositif dans son ensemble, constitué des blocs 6a, 6b et des parties d'insonorisation 2 et d'étanchéité 3, est réalisé par moulage dans une matière déformable. Cette matière est une mousse de polyuréthanne pour l'insonorisation de la conduite d'air, et à pores fermés pour assurer son étanchéi- té.The device as a whole, consisting of blocks 6a, 6b and soundproofing 2 and sealing 3 parts, is produced by molding in a deformable material. This material is a polyurethane foam for soundproofing the air duct, and with closed pores to ensure its airtightness.
Avantageusement, les blocs 6a, 6b sont montés en légère compression dans leur logement homologue correspondant, comme le montrent les flèches C de la figure 3. Ainsi, le dispositif est immobilisé sur la conduite 1 par ses moyens de fixation 6a et 6b.Advantageously, the blocks 6a, 6b are mounted in slight compression in their corresponding homologous housing, as shown by the arrows C in FIG. 3. Thus, the device is immobilized on the pipe 1 by its fixing means 6a and 6b.
Pour fabriquer le dispositif selon l'invention, on procède d'abord à une première étape de moulage de l'ensemble que forment les parties d'insonorisation 2 et d'étanchéité 3. Avantageusement, une seule opération suffit pour réaliser cet ensemble, contrairement au procédé de fabrication des dispositifs de la technique antérieure. Ainsi, on évite d'assembler par collage le joint d'étanchéité sur le joint d'insonorisation, tout en conservant la structure de la conduite 1. On procède ensuite à une seconde étape de découpe pour former les blocs 6a par bossage.To manufacture the device according to the invention, a first step of molding the assembly is carried out, formed by the soundproofing 2 and sealing 3 parts. Advantageously, a single operation is sufficient to produce this assembly, unlike the manufacturing process of the devices of the prior art. This avoids assembling the seal on the soundproofing seal by gluing, while retaining the structure of the pipe 1. Next, a second cutting step is carried out to form the blocks 6a by bossing.
Bien entendu, l'invention n'est pas limitée à la forme de réalisation décrite précédemment à titre d'exemple, elle s'é- tend à d'autres variantes.Of course, the invention is not limited to the embodiment described above by way of example, it extends to other variants.
Ainsi, on comprendra que le nombre de blocs de fixation 6a, 6b que comporte le dispositif peut varier suivant les besoins de l'installation, par exemple en fonction d'un débit de ventilation maximum.Thus, it will be understood that the number of fixing blocks 6a, 6b that the device comprises can vary according to the needs of the installation, for example as a function of a maximum ventilation rate.
En outre, le matériau utilisé pour la fabrication du dispositif selon l'invention peut être différent suivant les applications.In addition, the material used for the manufacture of the device according to the invention may be different depending on the applications.
Par ailleurs, la forme générale du dispositif s'adapte sensiblement à celle de la conduite d'air. Ainsi, elle peut être circulaire ou elliptique plutôt que rectangulaire, suivant la forme de la conduite. Enfin, le dispositif de l'invention n'est pas limité à une application pour un véhicule automobile. Furthermore, the general shape of the device adapts substantially to that of the air duct. Thus, it can be circular or elliptical rather than rectangular, depending on the shape of the pipe. Finally, the device of the invention is not limited to an application for a motor vehicle.
