Abstract
Description
L'invention concerne les blocs optiques montés à l'arrière des véhicules automobiles et, plus particulièrement, un agencement permettant d'intégrer une antenne radioréceptrice à un tel bloc. The invention relates to optical units mounted on the rear of motor vehicles and, more particularly, to an arrangement for integrating a radio receiving antenna into such an unit.
Les antennes extérieures utilisées avec les postes radiorécepteurs des véhicules automobiles présentent un certain nombre d'inconvénients. Elles nécessitent, en effet, un perçage de la carrosserie d'où des risques de corrosion, elles sont inesthétiques lorsqu'elles sont fixes et coûteuses lorsqu'elles sont rétractables électriquement, en outre elles sont fragiles car exposées à des chocs et des dégradations. C'est pourquoi on cherche à les intégrer de façon plus étroite au véhicule. On a ainsi proposé des antennes incorporées dans le vitrage du pare-brise. Cette solution est coûteuse et peu fiable, en effet, pour ne pas gêner la visibilité on est obligé d'utiliser des fils très fins, ce qui entraîne des problèmes de liaison électrique au niveau des connexions. The external antennas used with radio receiver stations of motor vehicles have a certain number of drawbacks. They require, in fact, a drilling of the body where corrosion risks, they are unsightly when they are fixed and expensive when they are electrically retractable, in addition they are fragile because exposed to shocks and degradations. This is why we are trying to integrate them more closely into the vehicle. There have thus been proposed antennas incorporated in the glazing of the windshield. This solution is expensive and unreliable, in fact, in order not to obstruct visibility, it is necessary to use very fine wires, which leads to problems of electrical connection at the level of the connections.
Pour remédier à ces divers inconvénients, l'invention propose d'intégrer l'antenne radioréceptrice au bloc optique arrière du véhicule. Dans les modèles actuels ce bloc est, en effet, d'une taille suffisante pour permettre d'y loger la longueur de fil nécessaire, il comporte en outre des zones sans dispositif d'éclairage dans lesquelles la présence du fil ne sera donc pas gênante. To overcome these various drawbacks, the invention proposes to integrate the radio receiving antenna into the rear optical unit of the vehicle. In current models, this block is, in fact, of a size sufficient to allow the necessary length of wire to be accommodated there, it also comprises zones without a lighting device in which the presence of the wire will therefore not be a nuisance .
Pour ce faire, il est proposé un bloc optique arrière de véhicule automobile composé d'un boîtier et d'une plaque de recouvrement frontale laquelle comporte au moins une zone dont la paroi interne est formée d'éléments rétro-réfléchissants pour remplir une fonction catadioptrique, ledit bloc étant remarquable en ce qu'un fil formant antenne radioréceptrice est rendu solidaire de la paroi interne de la zone catadioptrique précitée. To do this, a rear optical unit of a motor vehicle is proposed, composed of a housing and a front cover plate which comprises at least one zone, the internal wall of which is formed of retro-reflecting elements to fulfill a retro-reflecting function. , said block being remarkable in that a wire forming a radio receiving antenna is made integral with the internal wall of the aforementioned catadioptric zone.
Dans un mode de réalisation, le fil est collé sur la paroi interne de la zone catadioptrique. In one embodiment, the wire is glued to the internal wall of the retro-reflecting zone.
Dans un second mode de réalisation, il est surmoulé dans ladite paroi. In a second embodiment, it is molded into said wall.
Dans un troisième mode de réalisation, le fil d'antenne est rendu solidaire d'une platine spécifique, elle-même fixée sur la paroi interne de la zone catadioptrique. In a third embodiment, the antenna wire is made integral with a specific plate, itself fixed on the internal wall of the catadioptric zone.
De façon préférentielle, la zone catadioptrique est placée dans une position sensiblement médiane de la plaque de recouvrement frontale. Preferably, the retro-reflecting zone is placed in a substantially central position of the front cover plate.
D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui va suivre, pour la compréhension de laquelle on se reportera aux dessins annexés, dans lesquels
- La figure 1 est une vue arrière partielle d'un
véhicule automobile montrant un bloc optique arrière
agencé selon l'invention et,
- La figure 2 est une vue en section selon AA de la
figure 1.Other characteristics and advantages of the invention will appear on reading the detailed description which follows, for the understanding of which reference will be made to the accompanying drawings, in which
- Figure 1 is a partial rear view of a
motor vehicle showing rear light unit
arranged according to the invention and,
- Figure 2 is a sectional view along AA of the
figure 1.
Sur la figure 1 on voit bien un bloc optique 1 intégré à l'arrière d'un véhicule automobile, entre le volet 2 de fermeture du coffre, l'aile 3 et le pare-choc 4. Comme cela se fait habituellement, ce bloc optique est composé d'un boîtier 5 (figure 2) dans lequel sont regroupés les différents indicateurs de signalisation, disposés dans des logements 6,7 présentant des formes appropriées, par exemple parabolique. On n'a pas représenté, sur la figure 2, la platine arrière dudit boîtier qui supporte les lampes d'éclairage, ces pièces n'étant pas nécessaires à la compréhension de l'invention. In Figure 1 we can see an optical unit 1 integrated at the rear of a motor vehicle, between the flap 2 for closing the trunk, the wing 3 and the bumper 4. As is usually done, this block optic consists of a housing 5 (Figure 2) in which are grouped the various signaling indicators, arranged in housings 6,7 having suitable shapes, for example parabolic. FIG. 2 does not show the rear plate of said housing which supports the lighting lamps, these parts not being necessary for understanding the invention.
Le boîtier 5 est fermé, vers l'extérieur, par une plaque frontale 8 formant couvercle, en matière plastique colorée, composée de zones 9,10,11 différant les unes des autres, soit par la couleur, soit par la structure de leur paroi interne, de façon à émettre des impressions lumineuses différentes. The housing 5 is closed, towards the outside, by a front plate 8 forming a cover, of colored plastic, composed of zones 9, 10, 11 differing from each other, either by the color or by the structure of their wall internal, so as to emit different light impressions.
C'est ainsi que la zone 11 est aménagée pour remplir une fonction de rétro-réflexion catadioptrique. A cet effet, sa paroi interne 12 est composée d'éléments 16 en forme de prisme, trièdre ou analogue. Selon l'invention, un fil 13 destiné à faire fonction d'antenne radioréceptrice est intégré, par exemple par surmoulage ou collage, à la paroi interne 12 de la zone catadioptrique 11. Le fil est disposé entre les facettes des éléments 16 adjacents, de façon à ne pas altérer les fonctions optiques de ces éléments, il forme ainsi un réseau qui peut, par exemple, avoir une forme sinusoïdale. This is how zone 11 is arranged to fulfill a catadioptric retro-reflection function. For this purpose, its internal wall 12 is composed of elements 16 in the form of a prism, trihedron or the like. According to the invention, a wire 13 intended to act as a radio receiving antenna is integrated, for example by overmolding or gluing, to the internal wall 12 of the retro-reflecting zone 11. The wire is placed between the facets of the adjacent elements 16, of so as not to alter the optical functions of these elements, it thus forms a network which can, for example, have a sinusoidal shape.
Un connecteur 14 relie le fil d'antenne 13 au faisceau 15 du récepteur radio. Ce connecteur peut être spécifique ou intégré à la connectique d'ensemble du bloc optique. A connector 14 connects the antenna wire 13 to the harness 15 of the radio receiver. This connector can be specific or integrated into the overall connection of the optical unit.
Un autre mode de réalisation de l'invention (non représenté) consisterait à intégrer l'antenne dans une platine spécifique, elle-même fixée, par tout moyen approprié (vissage...) à la paroi interne 12. Another embodiment of the invention (not shown) would consist in integrating the antenna in a specific plate, itself fixed, by any appropriate means (screwing, etc.) to the internal wall 12.
Pour que l'antenne fonctionne sans risque d'interférence, il est nécessaire qu'elle soit implantée à un certaine distance des parties métalliques du véhicule qui entourent le bloc optique arrière. Cette distance doit être au moins de 15 mm. Bien que l'épaisseur du boîtier 5 garantisse déjà cette distance, il est avantageux de prévoir une implantation de la zone catadioptrique 11 dans une position médiane par rapport aux autres zones de la plaque frontale 8. For the antenna to operate without risk of interference, it is necessary that it be located at a certain distance from the metal parts of the vehicle which surround the rear optical unit. This distance must be at least 15 mm. Although the thickness of the housing 5 already guarantees this distance, it is advantageous to provide an implantation of the catadioptric zone 11 in a middle position relative to the other zones of the front plate 8.
