Titre : Protection thermique passive par une grille d’aération d’un boitier de connectivité Title: Passive thermal protection by a ventilation grille of a connectivity box
La présente invention revendique la priorité de la demande française 2010990 déposée le 27.10.2020 dont le contenu (texte, dessins et revendications) est ici incorporé par référence The present invention claims the priority of French application 2010990 filed on 27.10.2020, the content of which (text, drawings and claims) is incorporated herein by reference.
La présente invention appartient au domaine des composants électroniques en charge de la connectivité d’un véhicule terrestre à moteur. En particulier, elle concerne le refroidissement passif d’un boitier de connectivité logé dans une ouverture du pavillon du véhicule. The present invention belongs to the field of electronic components responsible for the connectivity of a motorized land vehicle. In particular, it relates to the passive cooling of a connectivity box housed in an opening in the roof of the vehicle.
On entend par « véhicule terrestre à moteur » tout type de véhicule tel qu’un véhicule automobile, un cyclomoteur, un avion, un train, une motocyclette, un robot de stockage dans un entrepôt, etc. “Motor land vehicle” means any type of vehicle such as a motor vehicle, a moped, an airplane, a train, a motorcycle, a storage robot in a warehouse, etc.
On entend par « logé dans une ouverture du pavillon » que le boitier de connectivité est placé dans l’ouverture. En particulier, Il peut être inséré dans un logement (cavité de la carrosserie dédiée à la réception du boitier) puis collé ou vissé. Dans un mode de réalisation, le boitier est collé ou vissé sur la carrosserie, au-dessus d’une ouverture. “Housed in an opening in the roof” means that the connectivity box is placed in the opening. In particular, it can be inserted into a housing (cavity of the bodywork dedicated to receiving the case) then glued or screwed. In one embodiment, the box is glued or screwed to the bodywork, above an opening.
Les boitiers de connectivité de dernière génération sont généralement liés directement à une surface extérieure du véhicule. Un tel agencement pose des problèmes de surchauffe des composants électroniques compris dans le boitier. Ces composants électroniques génèrent eux-mêmes une importante énergie thermique (chaleur) et, de par leur disposition sur la carrosserie, subissent l’énergie thermique apportée par l’environnement extérieur. The latest generation connectivity boxes are generally linked directly to an exterior surface of the vehicle. Such an arrangement poses problems of overheating of the electronic components included in the box. These electronic components themselves generate significant thermal energy (heat) and, by their arrangement on the bodywork, are subject to the thermal energy provided by the external environment.
Typiquement, un boitier de connectivité générant lui-même une importante énergie thermique logé dans une carrosserie peinte d’une couleur sombre (couleur de la carrosserie), recevant directement les rayons du soleil peut voir son fonctionnement dégradé. Typically, a connectivity box itself generating significant thermal energy housed in a body painted in a dark color (body color), receiving direct sunlight can see its operation degraded.
Il existe donc un besoin pour limiter les effets de surchauffe des boitiers de connectivité. There is therefore a need to limit the effects of overheating of the connectivity boxes.
La présente invention vient améliorer la situation. A cet effet un premier aspect de l’invention concerne un véhicule terrestre à moteur comportant : The present invention improves the situation. To this end, a first aspect of the invention relates to a land motor vehicle comprising:
- un pavillon, une face du pavillon étant à l’extérieur du véhicule ; - a roof, one side of the roof being outside the vehicle;
- une garniture de pavillon, une face de la garniture de pavillon étant dans l’habitacle du véhicule ; - a headliner, one side of the headliner being in the passenger compartment of the vehicle;
- un boitier de connectivité logé dans une ouverture du pavillon ; dans lequel la garniture de pavillon comporte une grille d’aération configurée pour une circulation d’air entre l’habitacle et un espace intermédiaire formé entre le pavillon et la garniture de pavillon. - a connectivity box housed in an opening in the roof; wherein the headliner has an air vent configured for airflow between the passenger compartment and an interspace formed between the headliner and the headliner.
Le réservoir de refroidissement ainsi défini met de l’air frais, ou moins au moins moins chaud, à dispositif du boitier de connectivité. The cooling tank thus defined puts cool air, or less at least less hot, to the device of the connectivity box.
En effet, la circulation d’air avec l’habitacle permet au réservoir d’être à une température proche de celle de l’habitacle. La climatisation de l’habitacle est ainsi typiquement avantageusement réutilisée. Indeed, the circulation of air with the passenger compartment allows the tank to be at a temperature close to that of the passenger compartment. The air conditioning of the passenger compartment is thus typically advantageously reused.
Dans un mode de réalisation, boitier de connectivité comporte une antenne et un boitier de traitement. In one embodiment, the connectivity box comprises an antenna and a processing box.
Dans un mode de réalisation, le boitier de traitement est compris dans l’espace intermédiaire. In one embodiment, the processing box is included in the intermediate space.
Dans un mode de réalisation, le boitier de connectivité comporte un ventilateur configuré pour intensifier la circulation d’air. In one embodiment, the connectivity box includes a fan configured to intensify air circulation.
Un deuxième aspect de l’invention concerne un procédé d’émission d’une donnée par un boitier de connectivité d’un véhicule terrestre à moteur comportant : A second aspect of the invention relates to a method for transmitting data by a connectivity box of a motorized land vehicle comprising:
- un pavillon, une face du pavillon étant à l’extérieur du véhicule ; - a roof, one side of the roof being outside the vehicle;
- une garniture de pavillon, une face de la garniture de pavillon étant dans l’habitacle du véhicule ; - a headliner, one side of the headliner being in the passenger compartment of the vehicle;
- un boitier de connectivité logé dans une ouverture du pavillon ; dans lequel la garniture de pavillon comporte une grille d’aération configurée pour une circulation d’air entre l’habitacle et un espace intermédiaire formé entre le pavillon et la garniture de pavillon ; le procédé comportant les étapes de : - a connectivity box housed in an opening in the roof; wherein the headliner includes an air vent configured for air circulation between the passenger compartment and an intermediate space formed between the headliner and the headliner; the method comprising the steps of:
- traitement de la donnée par un composant électronique compris dans le boitier de connectivité ; - data processing by an electronic component included in the connectivity box;
- émission de la donnée traitée par une antenne comprise dans le véhicule. - transmission of the processed data by an antenna included in the vehicle.
Un troisième aspect de l’invention concerne un procédé de réception d’un signal par un boitier de connectivité d’un véhicule terrestre à moteur comportant : un pavillon, une face du pavillon étant à l’extérieur du véhicule ; une garniture de pavillon, une face de la garniture de pavillon étant dans l’habitacle du véhicule ; un boitier de connectivité logé dans une ouverture du pavillon ; dans lequel la garniture de pavillon comporte une grille d’aération configurée pour une circulation d’air entre l’habitacle et un espace intermédiaire formé entre le pavillon et la garniture de pavillon ; le procédé comportant les étapes de : réception du signal par un antenne comprise dans le véhicule; traitement du signal par un composant électronique compris dans le boitier de connectivité. D’autres caractéristiques et avantages de l’invention apparaîtront à l’examen de la description détaillée ci-après, et des dessins annexés sur lesquels : A third aspect of the invention relates to a method for receiving a signal by a connectivity box of a land motor vehicle comprising: a roof, one face of the roof being outside the vehicle; a headliner, one face of the headliner being in the passenger compartment of the vehicle; a connectivity box housed in an opening in the roof; wherein the headliner includes an air vent configured for air circulation between the passenger compartment and an intermediate space formed between the headliner and the headliner; the method comprising the steps of: receiving the signal by an antenna included in the vehicle; signal processing by an electronic component included in the connectivity box.

L’invention est décrite ci-après dans son application, non limitative, au cas d’un boitier de connectivité implanté sur un pavillon, encore appelé toit, d’un véhicule automobile. D’autres applications, telles qu’un boitier de connectivité implanté sur le guidon d’un vélo électrique ou disposé sur un phare d’un cyclomoteur sont également envisageables. The invention is described below in its non-limiting application to the case of a connectivity box installed on a roof, also called a roof, of a motor vehicle. Other applications, such as a connectivity box installed on the handlebars of an electric bicycle or placed on a headlight of a moped are also possible.
La figure 1 est un schéma illustrant un pavillon du véhicule comportant le boitier de connectivité selon un mode de réalisation de l’invention. Figure 1 is a diagram illustrating a roof of the vehicle comprising the connectivity box according to one embodiment of the invention.
En particulier, la figure 1 représente le pavillon 2 (une partie du pavillon est représentée sur la figure 1) du véhicule. In particular, Figure 1 shows the roof 2 (part of the roof is shown in Figure 1) of the vehicle.
Le boitier de connectivité 4 est compris sur le pavillon. En particulier, le boitier 4 est logé dans une ouverture du pavillon, comme cela sera illustré à la figure 4. The connectivity box 4 is included on the roof. In particular, the box 4 is housed in an opening in the roof, as will be illustrated in Figure 4.
La face visible du pavillon de la figure 1 est située à l’extérieur du véhicule. La figure 2 est un schéma illustrant le boitier de connectivité selon un mode de réalisation de l’invention. The visible face of the flag in FIG. 1 is located outside the vehicle. FIG. 2 is a diagram illustrating the connectivity box according to one embodiment of the invention.
Le boitier de connectivité 4 comporte une antenne 41 et un boitier de traitement 42. L’antenne, de type aileron de requin, comporte plusieurs antennes selon les canaux de communication concernés (wifi, cellulaire, etc.) qui sont raccordés à des composants présents dans le boitier 42. Lesdits composants sont configurés pour traiter, et donc par exemple pour moduler/démoduler, les signaux reçus par les antennes. The connectivity box 4 comprises an antenna 41 and a processing box 42. The antenna, of the shark fin type, comprises several antennas according to the communication channels concerned (wifi, cellular, etc.) which are connected to components present in the box 42. Said components are configured to process, and therefore for example to modulate/demodulate, the signals received by the antennas.
La figure 3 est un schéma illustrant le dessous du boitier de connectivité avec une mousse selon un mode de réalisation de l’invention. Figure 3 is a diagram illustrating the underside of the connectivity box with a foam according to one embodiment of the invention.
Le bas du boitier de connectivité 4 est ici représenté, notamment une partie basse du boitier de traitement 42. The bottom of the connectivity box 4 is represented here, in particular a lower part of the processing box 42.
Une mousse isolante 8 est assemblée au boitier de connectivité. Comme cela sera détaillé ci-après en référence à la figure 4, la mousse forme ainsi un réservoir de refroidissement sous le boitier de connectivité. En particulier, la mousse isolante épouse un contour de la face inférieure du boitier de connectivité. An insulating foam 8 is assembled to the connectivity box. As will be detailed below with reference to FIG. 4, the foam thus forms a cooling reservoir under the connectivity box. In particular, the insulating foam follows a contour of the lower face of the connectivity box.
La mousse isolante est assemblée par clipsage au boitier de connectivité. Un des clips 6 est représenté sur la figure 3. On entend par « assemblage par clipsage » tout assemblage ou une partie déformable est placé par déformation sur une autre partie, une fois l’assemblage terminé, la partie déformable reprend sa forme initiale et rend ainsi possible un assemblage des deux parties. The insulating foam is assembled by clipping to the connectivity box. One of the clips 6 is shown in Figure 3. The term "assembly by clipping" means any assembly where a deformable part is placed by deformation on another part, once the assembly is complete, the deformable part resumes its initial shape and returns thus possible an assembly of the two parts.
La figure 4 est un schéma illustrant une vue du boitier de connectivité logé dans le pavillon selon un mode de réalisation de l’invention. Figure 4 is a diagram illustrating a view of the connectivity box housed in the pavilion according to one embodiment of the invention.
Sur la figure 4, le boitier de connectivité 4 est logé dans une ouverture du pavillon 2. En particulier, l’antenne 41 sort au-dessus du pavillon et le boitier de traitement 42 est situé sous l’antenne et, au niveau de certaines parties telles que devant l’antenne, sous le pavillon. In FIG. 4, the connectivity box 4 is housed in an opening of the roof 2. In particular, the antenna 41 comes out above the roof and the processing box 42 is located under the aerial and, at certain parts such as in front of the aerial, under the roof.
Une garniture 12 de pavillon est comprise dans le véhicule. Elle délimite une partie haute de l’habitacle du véhicule. Elle comprend typiquement un textile ou plastique d’habillage de l’habitacle. Ainsi, une face de la garniture de pavillon étant dans l’habitacle du véhicule.A headliner 12 is included in the vehicle. It delimits an upper part of the passenger compartment of the vehicle. It typically includes a textile or plastic trim for the passenger compartment. Thus, one side of the headliner being in the passenger compartment of the vehicle.
Un espace intermédiaire est présent entre le pavillon 2 et la garniture 12. C’est dans cet espace qu’est compris le réservoir de refroidissement 14. An intermediate space is present between the roof 2 and the trim 12. It is in this space that the cooling tank 14 is included.
Une partie avant inférieure 81 , une partie avant supérieure 82 et une partie arrière 83 de la mousse 8 sont représentées. En effet, sur la figure 4, la partie avant (constituée des parties 81 et 82) de la mousse n’est pas compressée pour illustrer le positionnement de la mousse. Dans la réalité, une fois la garniture assemblée au pavillon sur lequel a été préalablement assemblé le boitier de connectivité, la partie avant constituée des parties 81 et 82 est compressé de sorte que la partie 81 n’est plus présente et la totalité de la partie avant compressé au niveau de la partie 82. La partie arrière 83 peut également être compressée, selon les formes de pavillon et d’habitacle des véhicules. A lower front part 81, an upper front part 82 and a rear part 83 of the foam 8 are shown. Indeed, in Figure 4, the front part (consisting of parts 81 and 82) of the foam is not compressed to illustrate the positioning of the foam. In reality, once the trim is assembled to the roof on which the connectivity box was previously assembled, the front part consisting of parts 81 and 82 is compressed so that part 81 is no longer present and the entire part before compressed at the level of the part 82. The rear part 83 can also be compressed, depending on the shapes of the roof and the passenger compartment of the vehicles.
Ainsi, un réservoir de refroidissement 14 est compris dans l’espace intermédiaire. Thus, a cooling tank 14 is included in the intermediate space.
Dans un mode de réalisation, le réservoir 14 n’est pas présent et la circulation d’air est uniquement faite avec l’espace intermédiaire. In one embodiment, the tank 14 is not present and the air circulation is only made with the intermediate space.
La garniture 12 de pavillon comporte une grille 10 d’aération configurée pour une circulation d’air entre l’habitacle et le réservoir de refroidissement. L’air est donc échangé avec l’habitacle et met ainsi à disposition de dispositif actifs de refroidissement, tel qu’un ventilateur, du boitier de connectivité de l’air frais. The headliner 12 includes a ventilation grille 10 configured for air circulation between the passenger compartment and the cooling tank. The air is therefore exchanged with the passenger compartment and thus provides active cooling devices, such as a fan, for the connectivity box with fresh air.
