VOLET D'OBTURATION ARTICULE POUR APPAREIL DE CHAUFFAGE
ET/OU DE CLIMATISATION D'UN HABITACLE DE VEHICULE
AUTOMOBILE
L'invention se rapporte à un volet d'obturation articulé en particulier pour appareil de chauffage et/ou de climatisation d'un habitacle de véhicule automobile. ARTICULATED SHUTTER FOR A HEATER
AND / OR AIR CONDITIONING OF A VEHICLE INTERIOR
AUTOMOBILE
The invention relates to a hinged shutter in particular for heating and / or air conditioning of a passenger compartment of a motor vehicle.
Il est connu dans l'art antérieur d'équiper les véhicules automobiles d'un ensemble de chauffage et/ou de climatisation qui comprend typiquement un châssis à l'intérieur duquel sont disposés un pulser, un évaporateur, un radiateur, et des conduites d'aération équipées de volets d'orientation de l'air expulsé en direction de différentes zones de l'habitacle. It is known in the prior art to equip motor vehicles with a heating and / or air conditioning assembly which typically comprises a chassis inside which a pulser, an evaporator, a radiator, and pipes are arranged. '' ventilation fitted with flaps for orienting the air expelled towards different areas of the passenger compartment.
Or, ces volets provoquent des bruits d'air, n'assurent pas une bonne étanchéité avec les conduites d'aération et ne restent pas suffisamment rigides pour supporter les turbulences créées par le flux d'air. However, these flaps cause air noise, do not provide a good seal with the ventilation pipes and do not remain rigid enough to withstand the turbulence created by the air flow.
Pour remédier à ces inconvénients, il a déjà été proposé de réaliser un garnissage du volet par injection de matière plastique sur de la mousse, ce qui permet d'avoir un bon accrochage mécanique de la mousse sur le volet, ou bien de coller la mousse absorbante directement sur le volet, puis de surmouler des joints d'étanchéité. To remedy these drawbacks, it has already been proposed to fill the shutter by injecting plastic onto foam, which allows good mechanical attachment of the foam to the shutter, or to glue the foam absorbent directly on the shutter, then overmold seals.
Cependant, ces solutions ne sont pas véritablement satisfaisantes tant au niveau de l'absorption des bruits et des vibrations que de celui de l'étanchéité ou de la rigidité. En effet, dans le cas où la mousse est simplement collée sur le volet, elle se décolle facilement et s'arrache ou provoque des bruits d'air importants. Dans le cas où la mousse fait également office d'étanchéité sur les portées d'accostage de la conduite d'aération, l'étanchéité reste insuffisante et augmente particulièrement la complexité et les coûts de la mise en oeuvre. However, these solutions are not really satisfactory as much in terms of absorption of noise and vibrations as in that of sealing or rigidity. Indeed, in the case where the foam is simply glued to the shutter, it is easily peeled off and tears off or causes significant air noises. In the case where the foam also acts as a seal on the bearing surfaces of the ventilation pipe, the seal remains insufficient and particularly increases the complexity and the costs of implementation.
L'invention propose, pour résoudre ces problèmes, un nouveau type particulier de volet pour appareil de chauffage et/ou de climatisation de véhicule dont la structure en éléments dissociés permet un montage facile ainsi qu'une une meilleure absorption des bruits aérodynamiques et une étanchéité renforcée. The invention proposes, to solve these problems, a new particular type of shutter for vehicle heating and / or air conditioning apparatus, the structure of which in dissociated elements allows easy mounting as well as better absorption of aerodynamic noise and sealing. strengthened.
Plus précisément, l'invention a pour objet un volet aérodynamique d'obturation articulé pour appareil de chauffage et/ou de climatisation d'un habitacle de véhicule automobile comprenant : More specifically, the subject of the invention is an aerodynamic hinged shutter component for heating and / or air conditioning apparatus of a passenger compartment of a motor vehicle comprising:

Un volet aérodynamique d'obturation 10 pour appareil de chauffage et/ou de climatisation d'un habitacle de véhicule automobile est illustré sur la figure 1. An aerodynamic shutter 10 for heating and / or air conditioning of a passenger compartment of a motor vehicle is illustrated in FIG. 1.
<Desc/Clms Page number 3> <Desc / Clms Page number 3>
Ce volet 10 articulé comprend une première partie centrale 11, ou support, réalisée en matière plastique rigide tel que du polypropylène ou du polyéthylène. Ce support 11 présente une forme plane de plaque munie, sur une tranche, de paliers creux 12. Ces paliers 12 permettent, à l'aide d'une commande de couplage tels que deux axes, l'articulation du volet lors de son utilisation pour bloquer ou laisser passer un flux d'air circulant dans une conduite d'aération (non représentée) dans laquelle est placé le volet. This articulated flap 10 comprises a first central part 11, or support, made of rigid plastic material such as polypropylene or polyethylene. This support 11 has a flat form of plate provided, on a wafer, with hollow bearings 12. These bearings 12 allow, with the aid of a coupling control such as two axes, the articulation of the flap during its use for block or allow a flow of air circulating in a ventilation duct (not shown) in which the shutter is placed.
Un matériau souple à base d'élastomère, tel que du SEBS, est surmoulé directement sur le support 11, notamment à l'endroit de nervures 13 et en périphérie pour former des lèvres d'étanchéité 14 avec la conduite d'aération pour réduire les fuites. A flexible elastomer-based material, such as SEBS, is molded directly onto the support 11, in particular at the location of ribs 13 and at the periphery to form sealing lips 14 with the ventilation duct to reduce the leaks.
Au moins un bloc de mousse absorbante 15 est posé sur les nervures 13 afin d'absorber les vibrations induites par le flux d'air. Le bloc de mousse absorbante 15 est divisé en trois parties séparées par deux nervures 13b qui sont en saillie par rapport au support 11 et dépassent de l'épaisseur de la mousse. At least one block of absorbent foam 15 is placed on the ribs 13 in order to absorb the vibrations induced by the air flow. The absorbent foam block 15 is divided into three parts separated by two ribs 13b which project from the support 11 and protrude from the thickness of the foam.
Un capot de maintien ajouré 16, formant une seconde partie rigide du volet 10, est monté de manière amovible sur le support 11 par clipsage. Le capot de maintien 16 présente un cadre 17 et une grille 18 qui permettent de maintenir la mousse 15 solidement sur le corps 11 du volet 10 tout en laissant celle-ci absorber correctement les vibrations indésirables. Les nervures 13b sont insérées dans des fentes du capot 16 pour le centrer et le bloquer en translation. Ces nervures 13b présentent par ailleurs un profil aérodynamique favorisant l'écoulement de l'air. An openwork retaining cover 16, forming a second rigid part of the flap 10, is removably mounted on the support 11 by clipping. The retaining cover 16 has a frame 17 and a grid 18 which make it possible to hold the foam 15 securely on the body 11 of the flap 10 while allowing the latter to correctly absorb unwanted vibrations. The ribs 13b are inserted into slots in the cover 16 to center it and block it in translation. These ribs 13b also have an aerodynamic profile promoting the flow of air.
La solution ainsi présentée permet de réaliser un volet 10 ayant une forme aérodynamique qui est favorable à la circulation de l'air et à la réduction des bruits de frottements, tout en permettant d'optimiser l'absorption des vibrations par la mousse absorbante 15. The solution thus presented makes it possible to produce a flap 10 having an aerodynamic shape which is favorable to the circulation of air and to the reduction of friction noises, while making it possible to optimize the absorption of vibrations by the absorbent foam 15.
L'étanchéité du volet 10 avec la conduites de circulation d'air dans laquelle il est placé est obtenue par l'emploi du surmoulage, ce qui autorise davantage de possibilités qu'avec les solutions de l'art antérieur. The tightness of the shutter 10 with the air circulation pipes in which it is placed is obtained by the use of overmolding, which allows more possibilities than with the solutions of the prior art.
Comme cela est illustré sur la variante de réalisation de la figure 2, le bloc de mousse 15 est fixé, par exemple par collage, sur une surface externe parfaitement plane d'un rabat 19 articulé sur un bord du support 11 par l'intermédiaire d'une charnière film 20 invisible. Ainsi, après avoir pivoté le rabat 19 autour de la charnière film 20 pour le placer sur le As illustrated in the alternative embodiment of FIG. 2, the foam block 15 is fixed, for example by gluing, on a perfectly flat external surface of a flap 19 articulated on an edge of the support 11 by means of 'an invisible film hinge 20. Thus, after having pivoted the flap 19 around the film hinge 20 to place it on the
<Desc/Clms Page number 4><Desc / Clms Page number 4>
support 11, comme cela est illustré par les flèches F, l'ensemble est solidarisé par des clips ou à chaud par des points de soudure ou des rivets. La mousse absorbante 15 est ainsi placée de la même manière que sur la figure 1 où elle est ensuite éventuellement maintenue par un capot 16. support 11, as illustrated by the arrows F, the assembly is secured by clips or hot by welding points or rivets. The absorbent foam 15 is thus placed in the same manner as in FIG. 1 where it is then optionally held by a cover 16.
Cette solution évite d'avoir à placer la mousse 15 de part et d'autre et/ou sur les nervures 13 du support 11, ce qui améliore sa fixation puisque la surface d'attache 19a du rabat 19 est parfaitement plane, la surface opposée 19b venant par ailleurs épouser lesdites nervures 13 une fois le rabat 19 rabattu sur le support 11. This solution avoids having to place the foam 15 on either side and / or on the ribs 13 of the support 11, which improves its fixing since the attachment surface 19a of the flap 19 is perfectly flat, the opposite surface 19b also coming to marry said ribs 13 once the flap 19 is folded over the support 11.
L'invention n'est pas limitée aux exemples décrits et représentés, donnés à titre d'illustration de l'objet de l'Invention. The invention is not limited to the examples described and shown, given by way of illustration of the subject of the invention.
Ainsi, un bloc de mousse 15 peut être disposé sur les deux faces du support 11 du volet 10. Le bloc absorbant 15 en mousse peut également dépasser ponctuellement latéralement du support 11 pour former les lèvres d'étanchéité 14. Thus, a block of foam 15 can be placed on both sides of the support 11 of the flap 10. The absorbent block 15 of foam can also punctually project laterally from the support 11 to form the sealing lips 14.
Les nervures peuvent être plus ou moins nombreuses et plus ou moins espacées en fonction des dimensions du bloc de mousse. The ribs can be more or less numerous and more or less spaced depending on the dimensions of the foam block.
Le capot de maintien peut être vissé ou fixé par tout autre moyen connu sur le support. The retaining cover can be screwed or fixed by any other known means on the support.
Plusieurs rabats 19 peuvent être articulés sur les bords du support, avec chacun un bloc de mousse absorbante 15. Several flaps 19 can be articulated on the edges of the support, each with a block of absorbent foam 15.
