Description

L'invention se situe dans le domaine des commandes d'ouverture extérieures de porte de véhicule, et concerne plus précisément une commande d'ouverture extérieure de porte latérale de véhicule automobile et un véhicule équipé d'une telle commande d'ouverture extérieure.The invention lies in the field of external vehicle door opening controls, and more specifically relates to an external opening control of a motor vehicle side door and a vehicle equipped with such an external opening control.

La vibration d'éléments mécaniques et l'engouffrement de flux d'air dans des parties d'un véhicule sont différentes sources de bruit qui peuvent devenir une source de gêne pour les passagers lorsque ces bruits atteignent l'habitacle.The vibration of mechanical elements and the engulfing of air flow in parts of a vehicle are different sources of noise that can become a source of annoyance for passengers when these noises reach the passenger compartment.

Ainsi, par exemple, l'engouffrement d'air dans le caisson des portes latérales d'un véhicule génère des bruits qui atteignent l'habitacle au travers de la jonction dite « coulisse-lécheur » entre la vitre et les joints « lécheurs » de la porte latérale. Il serait intéressant de pouvoir trouver une solution permettant d'atténuer ou de supprimer le bruit entrant dans l'habitacle par cette voie. Malheureusement, la position de la vitre montrant un jeu, il est difficile de résoudre ce problème en rendant étanche d'un point de vue acoustique ladite jonction « coulisse-lécheur ».Thus, for example, the engulfment of air in the box of the side doors of a vehicle generates noises which reach the passenger compartment through the so-called "slide-licker" junction between the window and the "licker" joints of the vehicle. the side door. It would be interesting to be able to find a solution making it possible to attenuate or eliminate the noise entering the passenger compartment by this route. Unfortunately, the position of the window showing play, it is difficult to resolve this problem by making said “slide-lick” junction acoustically tight.

L'engouffrement du flux d'air se fait notamment via la commande d'ouverture extérieure de la porte car la jonction entre la commande d'ouverture extérieure et la carrosserie du véhicule n'est pas étanche. Une solution efficace et économique à la diffusion de bruits dans l'habitacle en provenance du caisson de porte reste donc à trouver.The air flow is engulfed in particular via the external door opening control because the junction between the external opening control and the vehicle body is not tight. An effective and economical solution to the diffusion of noise in the passenger compartment from the door casing therefore remains to be found.

Des solutions pour diminuer les bruits générés par un flux d'air et en relation avec une commande d'ouverture extérieure de porte ont déjà été proposées. Ainsi, le document CN104863434 décrit une commande d'ouverture comprenant une plaque mobile entre une position de couverture et une position d'exposition de la commande d'ouverture, cette dernière position permettant à l'utilisateur d'accéder à la poignée de la commande d'ouverture. En position de couverture, la plaque recouvre la poignée permettant ainsi de réduire le bruit du vent généré lorsque le véhicule roule à grande vitesse. Malheureusement, cette solution apparaît comme complexe et nécessite d'adapter les commandes d'ouverture extérieures actuellement utilisées pour la mettre en œuvre. Par ailleurs la présence d'une telle plaque peut nuire au style et à l'esthétisme du véhicule.Solutions for reducing the noises generated by an air flow and in connection with an external door opening control have already been proposed. Thus, the document CN104863434 describes an opening control comprising a plate movable between a cover position and an exposure position of the opening control, the latter position allowing the user to access the handle of the opening control. In the cover position, the plate covers the handle, thus reducing the noise of the wind generated when the vehicle is traveling at high speed. Unfortunately, this solution appears to be complex and requires adapting the external opening controls currently used to implement it. Furthermore, the presence of such a plate can harm the style and aesthetics of the vehicle.

Les documents EP 0402780 et WO 200937187 décrivent des solutions pour rendre étanche l'articulation de la poignée ou sa jonction avec la porte afin que l'air ne s'engouffre pas via ces voies. Ainsi dans le document EP 0402780 , le moyen d'étanchéité est présent sur l'étrier de la commande d'ouverture et autour d'une ouverture par laquelle va passer une branche associée à la poignée et qui montre, lorsque la poignée n'est pas actionnée, un interstice au travers duquel de l'air peut circuler. Le moyen d'étanchéité est disposé au niveau de cet interstice et permet d'éviter que l'air ne pénètre dans la porte. Le document WO 200937187 décrit une poignée de porte comportant un profilé d'étanchéité situé entre le bord de la face arrière de la poignée disposée en regard de la tôle et la tôle extérieure de la porte. Ces solutions mettent en oeuvre des éléments situés en intérieur de la commande extérieure de porte et nécessitent donc de concevoir de nouvelles commandes.The documents EP 0402780 and WO 200937187 describe solutions for sealing the articulation of the handle or its junction with the door so that air does not rush through these channels. So in the document EP 0402780 , the sealing means is present on the yoke of the opening control and around an opening through which a branch associated with the handle will pass and which shows, when the handle is not actuated, a gap in the through which air can circulate. The sealing means is disposed at the level of this interstice and makes it possible to prevent air from entering the door. The document WO 200937187 describes a door handle comprising a sealing profile located between the edge of the rear face of the handle arranged facing the sheet and the outer sheet of the door. These solutions use elements located inside the exterior door control and therefore require the design of new controls.

Il serait intéressant de trouver une solution simple et économique pouvant s'appliquer aux commandes d'ouverture extérieures de portes actuellement utilisées et qui, de préférence, ne modifie pas leur aspect esthétique.It would be interesting to find a simple and economical solution which could be applied to the external opening controls of doors currently in use and which, preferably, does not modify their aesthetic appearance.

L'invention a pour objectif de répondre à au moins un des problèmes rencontrés dans l'art antérieur en proposant une commande d'ouverture extérieure de porte latérale comprenant au moins un écran acoustique disposé à sa surface et destiné à être positionné à l'intérieur du caisson de la porte.The object of the invention is to respond to at least one of the problems encountered in the prior art by proposing an external opening control for a side door comprising at least one acoustic screen disposed on its surface and intended to be positioned inside. of the door casing.

Dans la description qui suit, le terme « comprendre » est synonyme de « inclure » et n'est pas limitatif en ce qu'il autorise la présence d'autres éléments dans la commande d'ouverture et le véhicule auquel il se rapporte. Il est entendu que le terme « comprendre » inclut les termes « consister en ». Sur les différentes figures, les mêmes références désignent des éléments identiques ou similaires.In the description which follows, the term "include" is synonymous with "include" and is not limiting in that it allows the presence of other elements in the opening control and the vehicle to which it relates. It is understood that the term "include" includes the terms "consist of". In the various figures, the same references designate identical or similar elements.

On se référera en premier lieu à la figure 1 qui est une coupe transversale d'une commande 1 d'ouverture extérieure de porte 3 selon l'invention. La commande d'ouverture 1 extérieure de porte 3 comprend une poignée 5 et un étrier 7. Dans l'exemple représenté, l'étrier 7 est positionné à l'intérieur de la porte 3 (c'est-à-dire dans le caisson de porte) et la poignée 5 fait saillie sur la surface extérieure 9 de la porte 3 de manière à ce qu'un utilisateur puisse la saisir.We will first refer to the figure 1 which is a cross section of a control 1 for external opening of door 3 according to the invention. The door 3 external opening control 1 comprises a handle 5 and a bracket 7. In the example shown, the bracket 7 is positioned inside the door 3 (that is to say in the box door) and the handle 5 protrudes on the outer surface 9 of the door 3 so that a user can grip it.

L'étrier 7 comprend une face avant tournée vers l'extérieur du véhicule et une face arrière tournée vers l'intérieur de la porte. Comme il est visible sur la figure, la poignée 5 est en regard de la face avant de l'étrier 7 et en contact avec la surface extérieure 9 de la porte latérale. Lorsque le véhicule roule, un flux d'air est susceptible de s'infiltrer par des interstices entre la commande 1 d'ouverture de porte et la surface extérieure 9 de la porte. Ce flux d'air peut traverser l'étrier 7 et pénétrer dans le caisson de porte via des ouvertures présentes sur la face arrière de l'étrier 7.The bracket 7 comprises a front face turned towards the outside of the vehicle and a rear face turned towards the inside of the door. As can be seen in the figure, the handle 5 is opposite the front face of the bracket 7 and in contact with the outer surface 9 of the side door. When the vehicle is moving, an air flow is liable to infiltrate through interstices between the door opening control 1 and the exterior surface 9 of the door. This air flow can pass through the bracket 7 and enter the door box via openings on the rear face of the bracket 7.

L'invention est remarquable en ce que la commande d'ouverture 1 comprend au moins un écran 11 acoustique obstruant au moins partiellement les ouvertures présentées par ledit étrier 7 sur sa face arrière 13. Ainsi le ou les écrans acoustiques sont destinés à s'opposer au passage du flux d'air cherchant à pénétrer dans le caisson de porte au travers de la face arrière 13 de l'étrier 7.The invention is remarkable in that the opening control 1 comprises at least one acoustic screen 11 at least partially obstructing the openings presented by said yoke 7 on its rear face 13. Thus the acoustic screen or screens are intended to oppose each other. the passage of the air flow seeking to enter the door box through the rear face 13 of the bracket 7.

Dans l'exemple illustré, la commande d'ouverture 1 de porte présente un mécanisme d'actionnement de la poignée 5 logé dans l'étrier 7. L'étrier 7 présente une ouverture débouchant sur ce mécanisme et au moins un écran 11 est positionné pour obstruer cette ouverture. Si bien qu'au moins un écran 11 est positionné en regard du mécanisme d'actionnement de la poignée 5.In the example illustrated, the door opening control 1 has a mechanism for actuating the handle 5 housed in the bracket 7. The bracket 7 has an opening opening onto this mechanism and at least one screen 11 is positioned. to obstruct this opening. So that at least one screen 11 is positioned opposite the actuating mechanism of the handle 5.

Selon une mise en œuvre préférée, l'écran 11 ou les écrans acoustiques sont fixés à la commande d'ouverture 1. La fixation est réalisée par tout moyen, et de préférence par collage au moyen de colle ou de ruban adhésif. Le ou les écrans 11 sont collés sur l'étrier au niveau de leurs pourtours. Il est ainsi possible de ne fermer les ouvertures de l'étrier qu'une fois la commande d'ouverture extérieure mise en place sur la porte. Il est également possible de retirer l'écran 11 si l'on souhaite accéder aux éléments ou mécanismes qu'il masque.According to a preferred implementation, the screen 11 or the acoustic screens are attached to the opening control 1. The attachment is carried out by any means, and preferably by gluing using glue or adhesive tape. The screen or screens 11 are glued to the caliper at their periphery. It is thus possible to close the openings of the caliper only once the external opening control is in place on the door. It is also possible to remove the screen 11 if it is desired to access the elements or mechanisms that it hides.

Selon un mode réalisation particulier de l'invention, le recouvrement de face arrière de l'étrier 7 n'est pas total. En effet, il n'est pas nécessaire selon l'invention d'empêcher totalement l'air de pénétrer dans le caisson de porte, il suffit que le flux d'air pénétrant dans le caisson de porte soit suffisamment peu important pour ne pas générer de bruits perceptibles dans l'habitacle. Aussi, le ou les écrans acoustiques 11 peuvent être de taille relativement réduite par rapport aux dimensions de l'étrier 7. Par exemple, le ou les écrans acoustiques 11 peuvent être dimensionnés pour recouvrir de 50 à 100 %, de préférence de 50 à 70% de la surface de la face arrière de l'étrier 7. L'utilisation d'écrans acoustiques 11 de taille réduite par rapport à la taille de l'étrier 7 est avantageuse tant d'un point de vue économique qu'en termes de masse additionnelle qu'ils peuvent présenter pour le véhicule.According to a particular embodiment of the invention, the rear face of the caliper 7 is not fully covered. Indeed, it is not necessary according to the invention to completely prevent the air from entering the door box, it suffices that the flow of air entering the door box is sufficiently small not to generate noises perceptible in the passenger compartment. Also, the acoustic screen (s) 11 can be relatively small compared to the dimensions of the stirrup 7. For example, the acoustic screen (s) 11 can be sized to cover from 50 to 100%, preferably from 50 to 70. % of the area of the rear face of the caliper 7. The use of acoustic screens 11 of reduced size compared to the size of the caliper 7 is advantageous both from an economic point of view and in terms of additional mass that they can present for the vehicle.

Selon une mise en œuvre préférée de l'invention, le recouvrement de la face arrière 13 par l'écran ou les écrans 11 ne doit cependant pas empêcher l'écoulement de l'eau à l'intérieur de la porte 3. En effet, lors d'une pluie notamment, de l'eau est susceptible de pénétrer dans la commande d'ouverture 1 extérieure et ne doit pas y stagner. A cet effet, et comme il est représenté dans l'exemple de la figure 3, la fixation de l'écran ou des écrans 11 acoustiques peut être faite de façon discontinue. Par exemple, les rubans adhésifs peuvent être espacés de manière à laisser au moins un interstice 15 entre l'écran ou les écrans 11 acoustiques et la face arrière de l'étrier 7. Lorsque la fixation de l'écran et faite par collage, le fil de colle est interrompu par endroits. La taille de ce ou ces interstices 15 est bien entendu choisie pour autoriser le passage de gouttes d'eau.According to a preferred embodiment of the invention, the covering of the rear face 13 by the screen or screens 11 must not however prevent the flow of water inside the door 3. In fact, during rain in particular, water is likely to enter the external opening control 1 and must not stagnate there. For this purpose, and as shown in the example of figure 3 , the fixing of the screen or the acoustic screens 11 can be done discontinuously. For example, the adhesive tapes can be spaced so as to leave at least one gap 15 between the screen or the acoustic screens 11 and the rear face of the stirrup 7. When the screen is fixed and made by gluing, the glue thread is interrupted in places. The size of this or these interstices 15 is of course chosen to allow the passage of water drops.

Dans l'exemple de réalisation illustré sur la figure 2, on peut voir que la commande d'ouverture extérieure 1 présente un verrou 17 qui fait saillie sur la surface de la face arrière de l'étrier 7. Préférentiellement, le verrou 17 va traverser au moins un écran acoustique 11. A cette fin, l'écran 11 comprend avantageusement une zone prédécoupée ou comprend une zone frangible destinée à être percée par le verrou 17 de ladite commande lors de l'assemblage de l'écran 11 sur l'étrier 7. La présence d'une telle zone frangible ou prédécoupée permet d'utiliser le même modèle d'écran acoustique 11 que la commande d'ouverture 1 soit une commande d'ouverture extérieure avec verrou 17 ou sans. Lorsque la commande d'ouverture extérieure 1 ne comprend pas de verrou, l'écran acoustique 11 n'est pas percé lors de sa fixation sur l'étrier 7. Sur la figure 2, l'écran acoustique 11 présentait une zone prédécoupée en étoile avant d'être traversée par le verrou 17. En absence de verrou, la zone frangible ou prédécoupée s'oppose au passage du flux d'air vers l'intérieur du caisson de porte.In the embodiment illustrated on figure 2 , it can be seen that the external opening control 1 has a lock 17 which protrudes on the surface of the rear face of the caliper 7. Preferably, the lock 17 will pass through at least one acoustic screen 11. To this end, the screen 11 advantageously comprises a pre-cut zone or comprises a frangible zone intended to be pierced by the latch 17 of said control during assembly of the screen 11 on the bracket 7. The presence of such a frangible zone or precut makes it possible to use the same model of acoustic screen 11 that the opening control 1 is an external opening control with lock 17 or without. When the external opening control 1 does not include a lock, the acoustic screen 11 is not pierced when it is fixed to the bracket 7. On the figure 2 , the acoustic screen 11 had a pre-cut star-shaped zone before being crossed by the lock 17. In the absence of lock, the frangible or pre-cut zone opposes the passage of the air flow towards the interior of the door box.

Par ailleurs, la commande d'ouverture peut également comprendre des éléments mobiles sur sa face arrière tels que par exemple un câble (non représenté) faisant la liaison entre la poignée et le système d'ouverture de la porte. Ce câble longe l'étrier dans une ouverture longitudinale avant de ressortir à surface de la face arrière. De manière à ne pas empêcher le bon fonctionnement du mécanisme d'ouverture de la porte, le mouvement de ce câble ne doit pas être gêné par l'écran ou les écrans acoustiques. Ainsi, de préférence, le ou les écrans acoustiques 11 sont configurés et positionnés de manière à contourner ladite zone dans laquelle le câble peut se mouvoir. On comprendra qu'en évitant une telle zone, le ou les écrans acoustiques 11 ne peuvent pas assurer une étanchéité totale empêchant tout flux d'air de traverser l'étrier. L'invention est remarquable en ce qu'elle propose un compromis entre les besoins de liberté de mouvement de certains éléments de la commande et le fait de s'opposer à l'entrée d'air dans le caisson de porte, compromis selon lequel elle limite le flux d'air entrant dans le caisson de porte suffisamment pour qu'il ne génère plus de bruits audibles dans l'habitacle.Furthermore, the opening control may also include movable elements on its rear face such as for example a cable (not shown) making the connection between the handle and the door opening system. This cable runs along the caliper in a longitudinal opening before emerging on the surface of the rear face. So as not to prevent the proper functioning of the door opening mechanism, the movement of this cable must not be hampered by the screen or the acoustic screens. Thus, preferably, the acoustic screen or screens 11 are configured and positioned so as to bypass said zone in which the cable can move. It will be understood that by avoiding such a zone, the acoustic screen (s) 11 cannot ensure complete sealing preventing any flow of air from passing through the caliper. The invention is remarkable in that it offers a compromise between the needs for freedom of movement of certain elements of the control and the fact of opposing the entry of air into the door box, a compromise according to which it limits the flow of air entering the door box enough so that it no longer generates audible noises in the passenger compartment.

Le montage du ou des écrans 11 acoustiques sur la commande d'ouverture 1 peut se faire lors du montage de la commande d'ouverture 1 sur la porte 3 par un opérateur, n'impliquant pas de modification de la chaine de production des commandes d'ouverture 1.The mounting of the acoustic screen (s) 11 on the opening control 1 can be done during the assembly of the opening control 1 on the door 3 by an operator, not involving any modification of the production line of the controls. opening 1.

La forme de l'écran ou des écrans acoustiques 11 est choisie pour cloisonner efficacement les ouvertures de face arrière 13 de l'étrier 7 responsables du passage du flux d'air. A cet effet, le ou les écrans acoustiques 11 sont plaqués contre la face arrière 13 et en épousent les formes.The shape of the screen or acoustic screens 11 is chosen to effectively partition the rear face openings 13 of the stirrup 7 responsible for the passage of the air flow. For this purpose, the acoustic screen or screens 11 are pressed against the rear face 13 and follow its shapes.

Dans un mode de réalisation de l'invention, le ou au moins un écran acoustique 11 est formé en un matériau isolant sélectionné dans le groupe comprenant les polyesters, les polyéthylènes (PE), les polypropylènes (PP), les polystyrènes (PS), les polyamides (PA), les chlorures de polyvinyle (PVC), les copolymères éthylène-acétate de vinyle (EVA).In one embodiment of the invention, the or at least one acoustic screen 11 is formed from an insulating material selected from the group comprising polyesters, polyethylenes (PE), polypropylenes (PP), polystyrenes (PS), polyamides (PA), polyvinyl chlorides (PVC), ethylene-vinyl acetate copolymers (EVA).

Afin de s'opposer efficacement au passage d'un flux d'air, le ou les écrans acoustiques en matériau isolant doivent présenter une épaisseur et une densité suffisante. A cette fin, l'homme du métier aura avantage à ce que l'écran 11 ou les écrans acoustiques présentent une épaisseur d'au moins 2 mm et une densité d'au moins 250 g/m2.In order to effectively oppose the passage of an air flow, the acoustic screen or screens made of insulating material must have sufficient thickness and density. To this end, those skilled in the art will benefit from the screen 11 or the acoustic screens having a thickness of at least 2 mm and a density of at least 250 g / m 2 .

Selon une mise en œuvre préférée de l'invention, au moins un écran acoustique 11 est formé en un matériau plastique présentant des propriétés élastiques, de préférence un élastomère choisi parmi un terpolymère d'éthylène de propylène et d'un diène (EPDM) ou un élastomère thermoplastique (TPE) ou un latex. Cette caractéristique de l'écran lui permet de présenter une double fonction. D'une part il s'oppose à l'entrée d'air dans le caisson et d'autre part il amortit les chocs pouvant survenir lorsque la porte latérale est fermée violement alors que la vitre est baissée. Dans un tel cas, la vitre peut osciller et heurter la commande d'ouverture extérieure générant un bruit. L'écran acoustique va donc amortir ce choc et le bruit en résultant.According to a preferred implementation of the invention, at least one acoustic screen 11 is formed from a plastic material exhibiting elastic properties, preferably an elastomer chosen from a terpolymer of ethylene propylene and a diene (EPDM) or a thermoplastic elastomer (TPE) or a latex. This feature of the screen allows it to have a dual function. On the one hand it opposes the entry of air into the box and on the other hand it absorbs the shocks that may occur when the side door is violently closed while the window is lowered. In such a case, the window may oscillate and strike the external opening control generating a noise. The acoustic screen will therefore absorb this shock and the resulting noise.

Ceci est illustré sur la figure 4, où l'on peut voir que la vitre 19 de la porte 3 latérale se présente à proximité de la face arrière de l'étrier 7. Le claquement de la porte 3 entraine une oscillation légère de la vitre 19 dans le sens transversal de la porte 3, générant un bruit lorsqu'elle entre en contact avec la commande d'ouverture 1 extérieure de porte.This is illustrated on the figure 4 , where one can see that the window 19 of the side door 3 is present near the rear face of the bracket 7. The slamming of the door 3 causes a slight oscillation of the window 19 in the transverse direction of the door 3, generating a noise when it comes into contact with the external door opening control 1.

Lorsque plusieurs écrans acoustiques sont présents, ceux-ci peuvent être tous en matériau isolant ou absorbant ou bien présenter une répartition de chacun. L'écran acoustique ou chaque écran acoustique peut également comprendre plusieurs couches de matériaux isolants et absorbants. Selon un exemple de réalisation non représenté, au moins un écran acoustique se présente sous forme d'une feuille bicouche comprenant une couche en matériau isolant et une couche en matériau élastique, de préférence la couche en matériau isolant est disposée en regard de la face arrière de l'étrier.When several acoustic screens are present, they can all be made of insulating or absorbent material or else have a distribution of each. The acoustic screen or each acoustic screen can also comprise several layers of insulating and absorbent materials. According to an exemplary embodiment not shown, at least one acoustic screen is in the form of a two-layer sheet comprising a layer of insulating material and a layer of elastic material, preferably the layer of insulating material is placed facing the rear face. of the caliper.
