  • be placed above the electronic component 16, in particular above the PCBA2 card on which said electronic component 16 rests;
  • be placed under the antenna cover 12.
  • be placed all or part under the roof 20. It is thus located inside the motor vehicle 2, namely in the passenger compartment 21, or partly in the passenger compartment 21 and partly in the roof 20.

On notera que par intérieur du véhicule automobile, on entend ainsi tout ce qui se situe en dessous de la face externe du toit 20, dans le mode de réalisation non limitatif du toit. Ainsi, cela comprend ce qui se situe dans le toit 20.It will be noted that the term “interior of the motor vehicle” is understood to mean everything which is located below the external face of the roof 20, in the non-limiting embodiment of the roof. Thus, this includes what is in the roof 20.

Dans un mode de réalisation non limitatif, la feuille métallique 17 est adaptée pour être disposée en regard de l'ouverture 200 du toit 20 et comprend une longueur totale L1 supérieure à ladite ouverture 200. Elle comprend des rebords 177 adaptés pour être disposés sous le toit 20.In a non-limiting embodiment, the metal sheet 17 is adapted to be placed opposite the opening 200 of the roof 20 and comprises a total length L1 greater than said opening 200. It comprises flanges 177 adapted to be placed under the roof. roof 20.

Sa largeur L2' (rebords 177 exclus) est supérieure ou égale à la largeur de l'ouverture 200.Its width L2 '(edges 177 excluded) is greater than or equal to the width of the opening 200.

La feuille métallique 17 permet de réaliser ainsi un blindage électrique (appelé également blindage électromagnétique) entre les signaux d'antenne de l'antenne primaire 15 et les signaux provenant du composant électronique 16. La fonction de protection CEM se trouve donc à l'intérieur de l'habitacle 21 du véhicule automobile 2.The metal foil 17 thus makes it possible to produce an electrical shielding (also called electromagnetic shielding) between the antenna signals of the primary antenna 15 and the signals coming from the electronic component 16. The EMC protection function is therefore located inside. of the passenger compartment 21 of the motor vehicle 2.

Dans un mode de réalisation non limitatif, la feuille métallique 17 comprend une taille (longueur et largeur) supérieure à la carte à circuit imprimé primaire PCBA1. Le blindage électrique est ainsi effectué sur toute la périphérie de l'antenne primaire 15 ; en particulier grâce aux parties 175 qui vont au-delà de la carte PCBA1 tel qu'illustré sur la figure 14. De cette manière, la protection CEM est plus efficace.In a non-limiting embodiment, the metal foil 17 comprises a size (length and width) greater than the primary printed circuit board PCBA1. The electrical shielding is thus carried out over the entire periphery of the primary antenna 15; in particular thanks to the parts 175 which go beyond the PCBA1 card as illustrated on the figure 14 . In this way, the EMC protection is more effective.

De plus, plus la surface du feuille métallique 17 est grande, meilleure est la dissipation thermique des composants électroniques de la carte PCBA2.In addition, the larger the surface of the metal foil 17, the better the heat dissipation of the electronic components of the PCBA2 board.

Dans un premier mode de réalisation non limitatif illustré à la figure 11a, la feuille métallique 17 est disposée en partie sous le toit 20, une partie étant disposée dans le toit 20. En particulier, la feuille métallique 17 comprend une partie 176 adaptée pour être disposée dans l'ouverture 200 du toit 20. Cette partie 176 intégrée dans le toit 20 comporte une longueur L2 et une largeur L2' inférieures à celles de l'ouverture 200 du toit 20. Le fait d'intégrer une partie 176 de la feuille métallique 17 dans le toit 20 permet de gagner un gain de place en hauteur dans le boîtier antenne 11 pour des composants électroniques 16.In a first non-limiting embodiment illustrated in figure 11a , the metal sheet 17 is disposed in part under the roof 20, a part being disposed in the roof 20. In particular, the metal sheet 17 comprises a part 176 adapted to be disposed in the opening 200 of the roof 20. This part 176 integrated in the roof 20 has a length L2 and a width L2 'less than those of the opening 200 of the roof 20. The fact of integrating a part 176 of the metal sheet 17 in the roof 20 saves space in height in the antenna box 11 for electronic components 16.

Dans un deuxième mode de réalisation non limitatif illustré à la figure 11b, la feuille métallique 17 est disposée complètement sous le toit 20. En particulier, la feuille métallique 17 comprend une partie 176 adaptée pour être disposée complètement sous le toit 20, à savoir sous l'ouverture 200 du toit 20. Cette partie 176 sous le toit 20 comporte une longueur L2 et une largeur L2' supérieures à celles de l'ouverture 200 du toit 20.In a second non-limiting embodiment illustrated in figure 11b , the metal sheet 17 is disposed completely under the roof 20. In particular, the metal sheet 17 comprises a part 176 adapted to be disposed completely under the roof 20, namely under the opening 200 of the roof 20. This part 176 under the roof 20. roof 20 has a length L2 and a width L2 'greater than those of the opening 200 of the roof 20.

On notera que le toit 20 du véhicule automobile 2 représente la masse du véhicule automobile 2.
La feuille métallique 17 est en contact avec le toit 20 par ses parties 175 via les vis de fixation 31. Les vis de fixation 31 permettent ainsi une mise à la masse de la feuille métallique 17. La feuille métallique 17 est donc connectée à la masse.
La feuille métallique 17 est fixée à la carte PCBA1 via les vis 32. La feuille métallique 17 permet ainsi une mise à la masse de la carte PCBA1 via lesdites vis 32.
La carte PCBA1 est connectée à la carte PCBA2 via le connecteur d'antenne 163. La carte PCBA1 étant à la masse, elle permet ainsi une mise à la masse de la carte PCAB2.It will be noted that the roof 20 of the motor vehicle 2 represents the mass of the motor vehicle 2.
The metal sheet 17 is in contact with the roof 20 via its parts 175 via the fixing screws 31. The fixing screws 31 thus allow grounding of the metal sheet 17. The metal sheet 17 is therefore connected to the ground. .
The metal foil 17 is fixed to the PCBA1 card via the screws 32. The metal foil 17 thus enables the PCBA1 card to be grounded via said screws 32.
The PCBA1 card is connected to the PCBA2 card via the antenna connector 163. The PCBA1 card being earthed, it thus enables the PCAB2 card to be earthed.

Ainsi, la mise à la masse est possible grâce à la vis de fixation 31 qui relie l'ensemble boîtier antenne 11 et feuille métallique au toit 20. On évite ainsi d'avoir des lignes de champs magnétiques qui contournent la feuille métallique 17 et qui pourraient entraîner des signaux parasites sur les signaux d'antenne ou des signaux parasites dans l'habitacle du véhicule automobile 2. Ainsi, on améliore les performances de l'antenne primaire 15.Thus, grounding is possible thanks to the fixing screw 31 which connects the antenna housing 11 and metal foil assembly to the roof 20. This avoids having magnetic field lines which bypass the metal foil 17 and which could cause spurious signals on the antenna signals or parasitic signals in the passenger compartment of the motor vehicle 2. Thus, the performance of the primary antenna 15 is improved.

Dans un mode de réalisation non limitatif, la feuille métallique 17 est adaptée pour dissiper l'énergie dégagée par le composant électronique 16. En effet, le composant électronique 16 quand il fonctionne chauffe et peut dégager beaucoup de chaleur. La feuille métallique 17 sert de dissipateur thermique. Dans le cas où il y a une pluralité de composants électroniques 16, afin de dissiper l'énergie de l'ensemble des composants électroniques 16 se trouvant sur la carte PCBA2, dans un mode de réalisation non limitatif (non illustré), la feuille métallique 17 recouvre entièrement l'ensemble desdits composants électroniques 16. Dans une variante de réalisation non limitative, le feuille métallique 17 peut comprendre une taille égale à la taille de la carte à circuit imprimé secondaire PCBA2. Cela permet d'avoir une plus grande surface de dissipation thermique pour l'ensemble des composants électroniques 16 de la carte PCBA2.
Pour améliorer la dissipation thermique, dans un mode de réalisation non limitatif, ladite feuille métallique 17 coopère avec une pâte thermique 164 décrite précédemment disposée sur la carte à circuit imprimé secondaire PCBA2 sur lequel repose le composant thermique 16.
Ainsi, la feuille métallique 17 en coopération avec la pâte thermique 164 sert de dissipateur thermique pour les composants électroniques 16 de la carte PCBA2. En effet, la chaleur dégagée par lesdits composants électroniques 16 se dissipe via la feuille métallique 17 dans le toit 20.
Afin de dissiper la chaleur dégagée par le composant électronique 16 plus rapidement, dans un mode de réalisation non limitatif illustré sur la coupe de la figure 11a ou la figure 11b, le feuille métallique 17 comprend en outre une patte d'appui 174 (appelé en anglais « gap pad ») de sorte à créer un espace d'air 174' entre le composant électronique 16 et le toit 20. Dans un exemple non limitatif, elle est de forme sensiblement carrée ou rectangulaire. Cette patte d'appui 174 s'étend sous le toit 20. De cette manière, la chaleur est évacuée plus rapidement à travers le toit 20. On remarquera que la patte d'appui 174 repose sur la pâte thermique 164 quand il y en a. On notera que la coupe de la figure 11a ou la figure 11b n'illustre pas le dispositif de fixation 171 de la feuille métallique 17.
On notera que la patte d'appui 174 est adaptée pour traverser le capot supérieur 13 du boîtier antenne 11 de sorte à être en regard dudit au moins un composant électronique 16.In a non-limiting embodiment, the metal foil 17 is suitable for dissipating the energy given off by the electronic component 16. In fact, the electronic component 16 when it is operating heats up and can give off a lot of heat. The metal foil 17 serves as a heat sink. In the case where there is a plurality of electronic components 16, in order to dissipate the energy of all the electronic components 16 located on the PCBA2 card, in a non-limiting embodiment (not illustrated), the metal foil 17 entirely covers all of said electronic components 16. In a non-limiting variant embodiment, the metal foil 17 may comprise a size equal to the size of the secondary printed circuit board PCBA2. This makes it possible to have a larger thermal dissipation surface for all of the electronic components 16 of the PCBA2 card.
To improve heat dissipation, in a non-limiting embodiment, said metal foil 17 cooperates with a thermal paste 164 described above arranged on the secondary printed circuit board PCBA2 on which the thermal component 16 rests.
Thus, the metal foil 17 in cooperation with the thermal paste 164 serves as a heat sink for the electronic components 16 of the PCBA2 card. Indeed, the heat given off by said electronic components 16 is dissipated via the metal foil 17 in the roof 20.
In order to dissipate the heat given off by the electronic component 16 more quickly, in a non-limiting embodiment illustrated on the section of the figure 11a or the figure 11b , the metal sheet 17 further comprises a support tab 174 (called in English "gap pad") so as to create an air space 174 'between the electronic component 16 and the roof 20. In a non-limiting example, it is substantially square or rectangular in shape. This support leg 174 extends under the roof 20. In this way, the heat is evacuated more quickly through the roof 20. It will be noted that the leg support 174 rests on thermal paste 164 when there is any. Note that the cut of the figure 11a or the figure 11b does not illustrate the fastener 171 of the metal sheet 17.
It will be noted that the support tab 174 is adapted to pass through the upper cover 13 of the antenna housing 11 so as to be opposite said at least one electronic component 16.

Dans des modes de réalisation non limitatifs, la feuille métallique 17 comprend :

  • au moins un dispositif de positionnement 178 pour le capot d'antenne 12 ;
  • au moins un dispositif de fixation 172 au capot d'antenne 12 et à l'antenne primaire 15 ;
  • au moins un dispositif de fixation 171 sur le toit 20 ;
  • une ouverture 173.
Ces éléments sont décrits en détail ci-après.In non-limiting embodiments, the metal foil 17 comprises:
  • at least one positioning device 178 for the antenna cover 12;
  • at least one fixing device 172 to the antenna cover 12 and to the primary antenna 15;
  • at least one fixing device 171 on the roof 20;
  • an opening 173.
These elements are described in detail below.

∘ Dispositif de positionnement 178 ∘ Positioning device 178

Dans un mode de réalisation non limitatif, le dispositif de positionnement 178 est un orifice adapté pour coopérer avec un dispositif de positionnement 128 du capot d'antenne 12 prévu à cet effet et décrit précédemment, à savoir un pion de positionnement. Cela facilite le montage du capot d'antenne 12 sur la feuille métallique 17. Dans un mode de réalisation non limitatif, la feuille métallique 17 comprend trois dispositifs de positionnement 178, à savoir ici trois orifices tel qu'illustré sur la figure 10, dont un est réparti à une extrémité de la feuille métallique 17 et les deux autres à l'autre extrémité de la feuille métallique 17. Les orifices 178 servent ainsi de référencement pour le capot d'antenne 12.In a non-limiting embodiment, the positioning device 178 is an orifice adapted to cooperate with a positioning device 128 of the antenna cover 12 provided for this purpose and described above, namely a positioning pin. This facilitates the mounting of the antenna cover 12 on the metal foil 17. In a non-limiting embodiment, the metal foil 17 comprises three positioning devices 178, namely here three holes as illustrated on the figure. figure 10 , one of which is distributed at one end of the metal sheet 17 and the other two at the other end of the metal sheet 17. The orifices 178 thus serve as a reference for the antenna cover 12.

Comme décrit précédemment, on notera que deux de ces dispositifs de positionnement 178 sont également adaptés pour coopérer avec deux dispositifs de positionnement 138 du capot supérieur 13 de sorte à positionner ladite feuille métallique 17 sur ledit capot supérieur 13. Ces deux dispositifs de positionnement 178 servent donc également à positionner la feuille métallique 17 sur le capot supérieur 13.As described above, it will be noted that two of these positioning devices 178 are also adapted to cooperate with two positioning devices 138 of the top cover 13 so as to position said metal sheet 17 on said top cover 13. These two Positioning devices 178 therefore also serve to position the metal sheet 17 on the top cover 13.

∘ Dispositif de fixation 172 ∘ Fixing device 172

Dans un mode de réalisation non limitatif, le dispositif de fixation 172 est un orifice adapté pour coopérer avec la vis 32 prévue à cet effet et avec l'orifice 152 de l'antenne primaire 15 décrit précédemment. En particulier, il est adapté pour être disposé en regard dudit orifice 152. Dans un mode de réalisation non limitatif, la feuille métallique 17 comprend six dispositifs de fixation 172, à savoir ici six orifices tel qu'illustré sur la figure 10 pour une bonne fixation. Ainsi, l'antenne primaire 15 est prise en sandwich entre le capot d'antenne 12 et la feuille métallique 17 et est bien fixée et ne risque pas de bouger. De plus, le dispositif de fixation 172 permet également de fixer la feuille métallique 17 sur le capot supérieur 13, grâce à la vis 32. Ainsi, la feuille métallique 17 est pris en sandwich entre l'antenne primaire 15, en particulier la carte PCBA1, et le capot supérieur 13.In a non-limiting embodiment, the fixing device 172 is an orifice adapted to cooperate with the screw 32 provided for this purpose and with the orifice 152 of the primary antenna 15 described above. In particular, it is adapted to be placed opposite said orifice 152. In a non-limiting embodiment, the metal sheet 17 comprises six fixing devices 172, namely here six orifices as illustrated in the figure. figure 10 for a good fixation. Thus, the primary antenna 15 is sandwiched between the antenna cover 12 and the metal sheet 17 and is well fixed and does not risk moving. In addition, the fixing device 172 also makes it possible to fix the metal sheet 17 on the top cover 13, thanks to the screw 32. Thus, the metal sheet 17 is sandwiched between the primary antenna 15, in particular the PCBA1 card. , and the top cover 13.

Ainsi, les vis 32 permettent donc d'assembler la feuille métallique, l'antenne primaire 15 et le capot supérieur 13 ensemble.Thus, the screws 32 therefore make it possible to assemble the metal sheet, the primary antenna 15 and the top cover 13 together.

∘ Dispositif de fixation 171 ∘ Fixing device 171

Dans un mode de réalisation non limitatif, le dispositif de fixation 171 est un orifice adapté pour coopérer avec la vis de fixation 31. Ladite vis de fixation 31 (qui fixe le boîtier antenne 11 avec le capot de protection 18) est en effet adaptée pour passer au travers dudit orifice 171.In a non-limiting embodiment, the fixing device 171 is an orifice adapted to cooperate with the fixing screw 31. Said fixing screw 31 (which fixes the antenna housing 11 with the protective cover 18) is in fact suitable for pass through said orifice 171.

Dans un mode de réalisation non limitatif, la feuille métallique 17 comprend deux dispositifs de fixation 171, à savoir deux orifices tel qu'illustré sur la figure 10 qui vont coopérer avec deux vis de fixation 31 pour une bonne fixation.In a non-limiting embodiment, the metal sheet 17 comprises two fixing devices 171, namely two orifices as illustrated on the figure. figure 10 which will cooperate with two fixing screws 31 for a good fixing.

Ainsi, au moins une vis de fixation 31 permet non seulement de fixer l'ensemble capot de protection 18, feuille métallique 17 et boîtier antenne 11 (via son capot supérieur 11) au toit 20, mais également de mettre à la masse l'ensemble capot de protection 18, feuille métallique 17 et boîtier antenne 11. C'est un dispositif de fixation simple et peu coûteux qui permet de remplir deux fonctions différentes en même temps. Dans l'exemple non limitatif illustré, deux vis de fixation 31 permettent d'effectuer ces deux fonctions à la fois.Thus, at least one fixing screw 31 makes it possible not only to fix the whole protective cover 18, metal sheet 17 and antenna housing 11 (via its upper cover 11) to the roof 20, but also to ground the assembly. protective cover 18, metal foil 17 and antenna housing 11. It is a simple and inexpensive fixing device which makes it possible to complete two different functions at the same time. In the non-limiting example illustrated, two fixing screws 31 make it possible to perform these two functions at the same time.

Dans un mode de réalisation non limitatif, la feuille métallique 17 comprend en outre une partie en saillie 175 comportant une patte 1750 dans laquelle est réalisé le dispositif de fixation 171. Cela permet de réaliser facilement l'orifice 171. Sur la figure 10, deux parties en saillie 175 sont illustrées, chacune comprenant une patte 1750. Ces parties en saillie 175 sont adaptées pour coopérer avec les parties en saillie 135 du capot supérieur 13. Elles sont situées au dessus de la carte PCAB2. Elles permettent d'améliorer le blindage électrique car elles se situent de part et d'autre de la carte PCBA1. Les vis de fixation 31 permettent aux parties en saillie 175 d'être bien en contact avec le toit 20 et donc permettent une bonne mise à la masse de la feuille métallique 17 comme vu précédemment.In a non-limiting embodiment, the metal sheet 17 further comprises a projecting portion 175 comprising a tab 1750 in which the fixing device 171 is made. This makes it possible to easily produce the orifice 171. On the figure 10 , two protruding parts 175 are illustrated, each comprising a tab 1750. These protruding parts 175 are adapted to cooperate with the protruding parts 135 of the top cover 13. They are located above the PCAB2 card. They make it possible to improve the electrical shielding because they are located on either side of the PCBA1 card. The fixing screws 31 allow the projecting parts 175 to be in good contact with the roof 20 and therefore allow good grounding of the metal sheet 17 as seen above.

La fixation sur le toit 20 est ainsi assurée. Par ailleurs, ces parties en saillie 175 sont adaptées pour en partie être en regard de l'ouverture 200 du toit 20. En revanche, leur patte 1750 est adaptée pour être disposée sous le toit 20 ce qui permet à la feuille métallique 17 d'être en contact avec le toit 20. La patte 1750 est en contact avec le toit 20 et permet avec la vis de fixation 31 une mise à la masse de la feuille métallique 17.Fixing on the roof 20 is thus ensured. Furthermore, these protruding parts 175 are adapted to partly be facing the opening 200 of the roof 20. On the other hand, their tab 1750 is adapted to be disposed under the roof 20 which allows the metal sheet 17 of be in contact with the roof 20. The tab 1750 is in contact with the roof 20 and, with the fixing screw 31, allows the metal sheet 17 to be grounded.

∘ Ouverture 173 ∘ Opening 173

L'ouverture 173 est adaptée pour laisser passer un connecteur d'antenne 163 de la carte PCBA2 sur laquelle repose le composant électronique 16.The opening 173 is adapted to pass an antenna connector 163 of the PCBA2 card on which the electronic component 16 rests.

Les figures 13 à 18 illustrent le montage du boîtier antenne 11 dans son ensemble et de la feuille métallique 17 sur ledit boîtier antenne 11.
Tel qu'illustré sur la figure 13, la feuille métallique 17 est disposée sur le capot supérieur 13 grâce aux dispositifs de positionnement 138 et 178. On notera que la feuille métallique 17 n'est pas en contact avec la carte PCBA2. Tel qu'illustré sur la figure 14, l'antenne primaire 15 (en particulier la carte PCBA1) est disposée sur la feuille métallique 17.
Tel qu'illustré sur la figure 15, le capot d'antenne 12 est positionné sur la feuille métallique 17 (et donc sur le capot supérieur 13) de sorte à recouvrir l'antenne primaire 15 grâce aux dispositifs de positionnement 128 et 178. Puis, l'ensemble capot supérieur 13, feuille métallique 17, carte PCBA1 et capot d'antenne 12 est vissé avec six vis 32 au travers des dispositifs de fixation 122, 132, 152, et 172. La figure 16 illustre lesdites vis 32. La carte PCBA1 (et par conséquent l'antenne primaire 15) est ainsi montée sur la feuille métallique 17 et donc sur le capot supérieur 13 grâce aux vis 32. Le capot d'antenne 12 est ainsi monté sur la feuille métallique 17 et donc sur le capot supérieur 13 grâce aux vis 32.
D'un autre côté, tel qu'illustré sur la figure 17, la carte PCBA2 comprenant le(s) composant(s) électronique(s) 16 est positionnée dans le capot inférieur 14.
Puis, tel qu'illustré sur la figure 18, le capot supérieur 13 (sur lequel repose la feuille métallique 17, l'antenne primaire 15 et le capot d'antenne 12) est assemblé au capot inférieur 14 grâce aux dispositifs de fixation 147 et 137, de sorte à former le boîtier antenne 11.
L'ensemble des éléments du boîtier antenne 11 sont ainsi déjà assemblés quand ledit boîtier antenne 11 est fourni à un opérateur qui monte le module d'antenne(s) 1 sur le véhicule automobile 2 comme décrit ci-après.The figures 13 to 18 illustrate the mounting of the antenna housing 11 as a whole and of the metal foil 17 on said antenna housing 11.
As shown on the figure 13 , the metal sheet 17 is placed on the top cover 13 by virtue of the positioning devices 138 and 178. It will be noted that the metal sheet 17 is not in contact with the PCBA2 card. As shown on the figure 14 , the primary antenna 15 (in particular the PCBA1 card) is placed on the metal sheet 17.
As shown on the figure 15 , the antenna cover 12 is positioned on the metal sheet 17 (and therefore on the upper cover 13) so as to cover the primary antenna 15 by means of the positioning devices 128 and 178. Then, the upper cover assembly 13, metal foil 17, PCBA1 board and antenna cover 12 is screwed with six screws 32 through the fasteners 122, 132, 152, and 172. The figure 16 illustrates said screws 32. The PCBA1 card (and therefore the primary antenna 15) is thus mounted on the metal sheet 17 and therefore on the top cover 13 thanks to the screws 32. The antenna cover 12 is thus mounted on the sheet metal 17 and therefore on the top cover 13 thanks to the screws 32.
On the other hand, as illustrated on the figure 17 , the PCBA2 card comprising the electronic component (s) 16 is positioned in the lower cover 14.
Then, as illustrated on figure 18 , the upper cover 13 (on which the metal sheet 17, the primary antenna 15 and the antenna cover 12 rest) is assembled to the lower cover 14 by means of the fixing devices 147 and 137, so as to form the antenna housing 11 .
All the elements of the antenna box 11 are thus already assembled when said antenna box 11 is supplied to an operator who mounts the antenna module (s) 1 on the motor vehicle 2 as described below.

• Montage • Assembly

Le module d'antenne(s) 1 ayant été décrit dans son ensemble, son montage est décrit -après.
Ainsi, pour monter l'ensemble du module antenne(s) 1 sur la carrosserie 20 du véhicule automobile 2, un opérateur effectue les opérations suivantes. L'opérateur est par exemple un opérateur chez un constructeur automobile. L'opérateur place le capot de protection 18 sur le toit 20 grâce aux pions 184 et aux pattes élastiques 185. Si un cache esthétique 19 est utilisé, dans ce cas, l'opérateur :

  • place le capot de protection 18 dans le cache esthétique 19 puis place l'ensemble sur le toit 20 ; ou
  • place l'ensemble capot de protection 18-cache esthétique 19 sur le toit 20 si les deux ont été pré-assemblés au préalable ou s'ils ne forment qu'une seule pièce.
Tel qu'illustré sur la figure 19, l'opérateur installe le boîtier antenne 11 sous la carrosserie 20 à l'intérieur du véhicule automobile 2, à savoir ici sous le toit 20 dans l'habitacle 21. L'opérateur positionne ainsi l'ensemble boîtier antenne 11, feuille métallique 17 sous le toit 20 de sorte que l'antenne primaire 15 et le capot d'antenne 12 passe au travers de l'ouverture 200 du toit 20, le capot d'antenne 12 se trouvant ainsi dans le capot de protection 18, et de sorte que la capot supérieur 13 touche le toit 20, à l'intérieur de l'habitacle 21. Le capot supérieur 13, le capot inférieur 14, la carte PCBA2 et les composants électroniques 16 se trouvent sous le toit 20. Le capot supérieur 13, le capot inférieur 14, la carte PCBA2 et les composants électroniques 16 se trouvent sous le toit 20. La feuille métallique 17 est tout ou partie sous le toit 20 selon le premier ou deuxième mode de réalisation choisi.
Tel qu'illustré sur la figure 20, la capot d'antenne 12 est ainsi recouvert par le capot de protection 18 qui a été disposé auparavant sur le toit 20 et est positionné dans le capot de protection 18 grâce aux protubérances de guidage et de fixation 127. Ainsi, l'opérateur n'a pas besoin de tenir le boîtier antenne 11 avec les mains puisque ce dernier est maintenu via son capot d'antenne 12 sous le toit 20. Ensuite, tel qu'illustré sur la figure 21, l'opérateur fixe l'ensemble boîtier antenne 11, feuille métallique 17 sur le toit 20 (à l'intérieur du véhicule automobile 2), grâce aux inserts primaires 181, aux orifices de fixation 201, aux inserts secondaires 131 et aux dispositifs de fixation 171, via les vis de fixation 31. Le toit 20 est pris en sandwich entre le boîtier antenne 11 et le capot de protection 18.
Le vissage permet d'effectuer une action mécanique de compression sur le joint d'étanchéité 182 ce qui permet d'assurer la fonction d'étanchéité de l'ensemble du module d'antenne(s) 1. Le joint d'étanchéité 182 est ainsi pris en sandwich entre la base 180 du capot de protection 18 et la surface extérieure du toit 20. Une partie du toit 20 est ainsi prise en sandwich entre le capot de protection 18 et le boîtier antenne 11.
L'ensemble du module d'antenne(s) 1 est ainsi fixé sur le toit 20.
La figure 22 illustre le cache esthétique 2 sur le toit 20 qui recouvre l'ensemble du module d'antenne(s) 1.
La coupe de la figure 23 illustre l'ensemble boîtier antenne 11, feuille métallique 17, capot de protection 18, cache esthétique 19, et antenne primaire 15 positionnés et fixés sur le toit 20.
On notera que l'opérateur peut très facilement démonter la feuille métallique 17 et le boîtier antenne 11 du toit 20 en dévissant les vis de fixation 31.The antenna module (s) 1 having been described as a whole, its assembly is described -after.
Thus, to mount the assembly of the antenna module (s) 1 on the body 20 of the motor vehicle 2, an operator performs the following operations. The operator is for example an operator at an automobile manufacturer. The operator places the protective cover 18 on the roof 20 using the pins 184 and the elastic tabs 185. If an aesthetic cover 19 is used, in this case, the operator:
  • places the protective cover 18 in the aesthetic cover 19 then places the assembly on the roof 20; or

The operator thus positions the antenna housing assembly 11, metal sheet 17 under the roof 20 so that the primary antenna 15 and the antenna cover 12 pass through the opening 200 of the roof 20, the antenna cover 12 thus being in the protective cover 18, and so that the upper cover 13 touches the roof 20, inside the passenger compartment 21. The upper cover 13, the lower cover 14, the PCBA2 card and the electronic components 16 are located under the roof 20. The upper cover 13, the lower cover 14, the PCBA2 card and the electronic components 16 are located under the roof 20. The metal sheet 17 is all or part under the roof 20 according to the first or second embodiment chosen.
As shown on the figure 20 , the antenna cover 12 is thus covered by the protective cover 18 which was previously placed on the roof 20 and is positioned in the protective cover 18 thanks to the guiding and fixing protuberances 127. Thus, the operator no. 'does not need to hold the antenna box 11 with the hands since the latter is held via its antenna cover 12 under the roof 20. Then, as illustrated on the figure. figure 21 , the operator fixes the antenna housing assembly 11, metal sheet 17 on the roof 20 (inside the motor vehicle 2), thanks to the primary inserts 181, the fixing holes 201, the secondary inserts 131 and the locking devices. fixing 171, via the fixing screws 31. The roof 20 is sandwiched between the antenna box 11 and the protective cover 18.
The screwing makes it possible to perform a mechanical compressive action on the seal 182 which makes it possible to ensure the sealing function of the entire antenna module (s) 1. The seal 182 is thus sandwiched between the base 180 of the protective cover 18 and the surface exterior of the roof 20. Part of the roof 20 is thus sandwiched between the protective cover 18 and the antenna box 11.
The whole of the antenna module (s) 1 is thus fixed to the roof 20.
The figure 22 illustrates the aesthetic cover 2 on the roof 20 which covers the entire antenna module (s) 1.
The cut of the figure 23 illustrates the antenna housing 11, metal foil 17, protective cover 18, aesthetic cover 19, and primary antenna 15 assembly positioned and fixed on the roof 20.
It will be noted that the operator can very easily remove the metal sheet 17 and the antenna box 11 from the roof 20 by unscrewing the fixing screws 31.
