Abstract

The antenna (1) is positioned inside a hollow body which is formed in the vehicle and is invisible from outside the vehicle. The hollow body is formed from a material which is permeable to radio waves. The antenna is of whip type and is positioned vertically to ensure optimal reception. The vehicle has a sandwich type structure and is formed from two skin layers which have a foam filler material positioned in between. The hollow body is formed by a zone in which the two skins have been removed from each other. The hollow body is at least partially filled with the filler material and includes a blocking device which prevents the antenna from vibrating.

Description

La présente invention concerne un agencement d'une antenne radio dans un véhicule automobile. The present invention relates to an arrangement of a radio antenna in a motor vehicle.

On connaît un agencement d'antenne selon lequel l'antenne, généralement de type fouet, est rapportée à la carrosserie du véhicule. Cependant, cet agencement connu a pour inconvénients d'être mal intégré à la carrosserie du véhicule, inesthétique, vulnérable et bruyant lorsque le véhicule se déplace à des vitesses relativement élevées. De plus, ce type d'agencement pose des problèmes lors du nettoyage du véhicule sous un portique à rouleaux de sorte qu'il est souvent nécessaire de prévoir une antenne amovible, solution peu pratique. An antenna arrangement is known according to which the antenna, generally of the whip type, is attached to the vehicle body. However, this known arrangement has the disadvantages of being poorly integrated into the vehicle body, unsightly, vulnerable and noisy when the vehicle is traveling at relatively high speeds. In addition, this type of arrangement poses problems when cleaning the vehicle under a roller gantry so that it is often necessary to provide a removable antenna, an impractical solution.

On connaît également un agencement d'antenne où l'antenne est électriquement éclipsable. Cependant, cette solution connue a pour inconvénients d'être relativement coûteuse, d'augmenter le poids dans son ensemble et d'occasionner des pannes de fonctionnement se traduisant par une antenne déployée en permanence. An antenna arrangement is also known where the antenna is electrically eclipsable. However, this known solution has the drawbacks of being relatively expensive, of increasing the weight as a whole and of causing operational failures resulting in an antenna deployed permanently.

La présente invention a pour but d'éliminer les inconvénients ci-dessus en proposant un agencement d'une antenne radio dans un véhicule automobile et qui est caractérisé en ce que l'antenne est disposée à l'intérieur d'un corps creux du véhicule en matériau perméable aux ondes radio de manière à être invisible de l'extérieur. The object of the present invention is to eliminate the above drawbacks by proposing an arrangement of a radio antenna in a motor vehicle and which is characterized in that the antenna is arranged inside a hollow body of the vehicle. made of material permeable to radio waves so as to be invisible from the outside.

Avantageusement, l'antenne se présente sous forme d'un élément allongé de type antenne fouet. Advantageously, the antenna is in the form of an elongated element of the whip antenna type.

De préférence, l'antenne est disposée verticalement ou sensiblement verticalement afin d'améliorer la réception. Preferably, the antenna is arranged vertically or substantially vertically in order to improve reception.

Dans le cas où la structure du véhicule est du type sandwich constituée de deux peaux entre lesquelles est interposé un matériau tel qu'un matériau de remplissage, le corps creux précité est formé par une zone dans laquelle les deux peaux sont éloignées l'une de l'autre. In the case where the structure of the vehicle is of the sandwich type made up of two skins between which is interposed a material such as a filling material, the abovementioned hollow body is formed by an area in which the two skins are distant from one the other.

Le corps creux est au moins partiellement rempli de matériau de remplisage. The hollow body is at least partially filled with filling material.

Des moyens sont prévus pour empêcher l'antenne de vibrer et, de préférence, ces moyens comprennent au moins un bloc, tel qu'un bloc de mousse, placé au voisinage d'une partie de l'antenne. Means are provided to prevent the antenna from vibrating and, preferably, these means comprise at least one block, such as a foam block, placed in the vicinity of a part of the antenna.

Le plan de masse de l'antenne se présente sous la forme d'une feuille en matériau électriquement conducteur, par exemple métallique, placée sur une surface interne du corps creux. The ground plane of the antenna is in the form of a sheet of electrically conductive material, for example metallic, placed on an internal surface of the hollow body.

De préférence, le corps creux se trouve au-dessus d'un passage de roue du véhicule et la feuille de plan de masse de l'antenne est placée sur ce passage. Preferably, the hollow body is located above a wheel arch of the vehicle and the ground plane sheet of the antenna is placed on this passage.

Enfin, le véhicule peut comporter plusieurs antennes dont chacune est disposée dans un corps creux. Finally, the vehicle may include several antennas, each of which is arranged in a hollow body.

L'invention sera mieux comprise et d'autres buts, caractéristiques, détails et avantages de celle-ci apparaîtront plus clairement au cours de la description explicative qui va suivre faite en référence au dessin schématique unique annexé donné uniquement à titre d'exemple illustrant un mode de réalisation de l'invention et représentant une vue arrière d'un véhicule automobile avec une coupe transversale partielle montrant l'emplacement de l'agencement d'antenne radio conforme à l'invention. The invention will be better understood and other objects, characteristics, details and advantages thereof will appear more clearly during the explanatory description which follows, made with reference to the attached single schematic drawing given solely by way of example illustrating a embodiment of the invention and representing a rear view of a motor vehicle with a partial cross section showing the location of the radio antenna arrangement according to the invention.

Le véhicule automobile représenté à la figure unique a de préférence une structure du type sandwich ou composite constituée de deux peaux 1, 2 formant respectivement la coque extérieure et la coque intérieure de carrosserie du véhicule et entre lesquelles est habituellement interposé un matériau (non représenté) tel qu'un matériau mousse de remplissage. The motor vehicle shown in the single figure preferably has a sandwich or composite type structure consisting of two skins 1, 2 respectively forming the outer shell and the inner shell of the vehicle body and between which a material is usually interposed (not shown). such as foam filling material.

Selon l'invention, une antenne 3 se présentant de préférence sous la forme d'un élément allongé de type antenne fouet, est disposée à l'intérieur d'un corps creux du véhicule réalisé en matériau perméable aux ondes radio de manière que l'antenne 3 soit invisible de l'extérieur. According to the invention, an antenna 3, preferably in the form of an elongated element of the whip antenna type, is arranged inside a hollow body of the vehicle made of material permeable to radio waves so that the antenna 3 is invisible from the outside.

De préférence, le corps creux est formé par une partie ou zone 4 de structure composite du véhicule, dans laquelle les deux peaux 1, 2 sont éloignées l'une de l'autre. Preferably, the hollow body is formed by a part or zone 4 of the vehicle's composite structure, in which the two skins 1, 2 are spaced from one another.

Dans l'exemple représenté, le corps creux 4 est dépourvu de matériau de remplissage. Cependant, il pourrait être partiellement ou entièrement rempli de ce matériau, essentiellement pour empêcher l'antenne de vibrer et éviter des bruits intempestifs, le matériau étant par exemple injecté après montage de l'antenne. Eventuellement, l'antivibration peut être assurée par un simple bloc de ce matériau, notamment un bloc de mousse, placé au voisinage d'une partie de l'antenne qui risque de vibrer. In the example shown, the hollow body 4 is devoid of filling material. However, it could be partially or completely filled with this material, essentially to prevent the antenna from vibrating and to avoid nuisance noise, the material being for example injected after mounting the antenna. Optionally, the anti-vibration can be ensured by a simple block of this material, in particular a block of foam, placed in the vicinity of a part of the antenna which risks vibrating.

Le plan de masse 5 de l'antenne 3 se présente sous la forme d'une feuille en matériau électriquement conducteur, par exemple métallique, placée sur une surface interne 6 du corps creux 4, qui se trouve au-dessus d'un passage 7 de roue 8 du véhicule. De la sorte, la feuille de plan de masse 5 est placée sur le passage 7 de roue 8 du véhicule. The ground plane 5 of the antenna 3 is in the form of a sheet of electrically conductive material, for example metallic, placed on an internal surface 6 of the hollow body 4, which is located above a passage 7 wheel 8 of the vehicle. In this way, the ground plane sheet 5 is placed on the wheel arch 7 of the vehicle.

L'agencement d'antenne radio conforme à l'invention n'altère pas l'aspect esthétique du véhicule, n'occasionne par de bruit désagréable lors du déplacement du véhicule à des vitesses relativement élevées et permet un nettoyage du véhicule sans risque de déformation, voire de rupture de l'antenne par les rouleaux d'un portique de nettoyage. De plus, il n'y a pas de poids supplémentaire, puisqu'il n'est pas nécessaire de prévoir un moteur électrique pour rentrer l'antenne.  The arrangement of radio antenna according to the invention does not alter the aesthetic appearance of the vehicle, does not cause unpleasant noise when moving the vehicle at relatively high speeds and allows cleaning of the vehicle without risk of deformation , or even rupture of the antenna by the rollers of a cleaning gantry. In addition, there is no additional weight, since it is not necessary to provide an electric motor to retract the antenna.

Enfin, l'invention ne se limite pas au seul mode de réalisation décrit et représenté, mais en couvre au contraire toutes les variantes. En particulier, si l'exemple décrit concerne un véhicule comportant une seule antenne, on ne sortirait pas du cadre de l'invention en prévoyant plusieurs antennes en fonction des différentes longueurs d'onde à capter, par exemple une antenne pour la radio et une pour le téléphone, celles-ci pouvant être dans un même corps creux ou dans des corps creux différents.  Finally, the invention is not limited to the single embodiment described and shown, but on the contrary covers all variants. In particular, if the example described relates to a vehicle comprising a single antenna, it would not go beyond the scope of the invention to provide several antennas according to the different wavelengths to be received, for example an antenna for the radio and a for the telephone, these may be in the same hollow body or in different hollow bodies.
