Abstract
Description
1 L'invention concerne un écran de protection thermique de véhicule automobile et un procédé de réalisation d'un tel écran. The invention relates to a motor vehicle thermal protection screen and a method for producing such a screen.
Il est connu de réaliser un écran de protection thermique de véhicule automobile comprenant une coque à base de matière plastique moulée et une feuille de réflexion de la chaleur revêtant tout ou partie d'une face de ladite coque. It is known to provide a motor vehicle thermal protection screen comprising a molded plastic shell and a heat reflection sheet coating all or part of a face of said shell.
Un tel écran est usuellement fixé sur la structure du véhicule par des moyens de fixation tel que des vis ou des lyres, ce qui représente une opération de montage très coûteuse. Such a screen is usually attached to the vehicle structure by fastening means such as screws or lyres, which represents a very expensive mounting operation.
De telles fixations sont utilisées dans les cas d'environnements très chauds, par exemple de température de l'ordre de 1000°C, et d'environnements moins chauds, par exemple de température inférieure à 250°C environ. Such fasteners are used in the case of very hot environments, for example temperature of the order of 1000 ° C, and less hot environments, for example temperature below about 250 ° C.
L'invention a pour but de proposer une solution alternative moins coûteuse adaptée aux environnements de température inférieure à 250°C environ. The object of the invention is to propose a less expensive alternative solution adapted to environments with a temperature below about 250 ° C.
A cet effet, et selon un premier aspect, l'invention propose un écran de protection thermique de véhicule automobile comprenant une coque à base de matière plastique moulée et une feuille de réflexion de la chaleur revêtant tout ou partie d'une face de ladite coque, ledit écran comprenant en outre des moyens de fixation à la structure du véhicule, lesdits moyens étant moulés d'une pièce avec ladite coque. For this purpose, and according to a first aspect, the invention proposes a thermal protection screen for a motor vehicle comprising a shell made of molded plastic material and a heat reflection sheet coating all or part of a face of said shell. said screen further comprising means for attachment to the vehicle structure, said means being molded integrally with said shell.
Ainsi, les moyens de fixation sont intégrés à l'écran, ce qui évite de les rapporter lors de l'opération de montage de l'écran sur la structure du véhicule. En outre, du fait de la température modérée de l'environnement, inférieure à 250°C environ, de telles fixations présentent la robustesse requise. Thus, the fastening means are integrated in the screen, which avoids reporting them during the mounting operation of the screen on the vehicle structure. In addition, because of the moderate temperature of the environment, less than about 250 ° C, such fasteners have the required robustness.
Selon un deuxième aspect, l'invention propose un procédé de réalisation d'un tel écran. 2 D'autres particularités et avantages de l'invention apparaîtront dans la description qui suit, faite en référence à la figure jointe qui est une représentation schématique partielle en coupe d'un écran selon une réalisation. According to a second aspect, the invention proposes a method of producing such a screen. Other features and advantages of the invention will appear in the description which follows, made with reference to the attached figure which is a partial schematic sectional representation of a screen according to one embodiment.
En référence aux figures, on décrit un écran 1 de protection thermique de véhicule automobile comprenant une coque 2 à base de matière plastique moulée, par exemple à base de polypropylène ou de polyamide, et une feuille 3 de réflexion de la chaleur revêtant tout ou partie d'une face de ladite coque, ledit écran comprenant en outre des moyens de fixation 4 à la structure du véhicule, lesdits moyens étant moulés d'une pièce avec ladite coque. With reference to the figures, a motor vehicle thermal protection screen 1 is described comprising a shell 2 based on a molded plastic material, for example based on polypropylene or polyamide, and a heat-reflecting sheet 3 covering all or part of one side of said shell, said screen further comprising fixing means 4 to the vehicle structure, said means being molded integrally with said shell.
Selon la réalisation représentée, les moyens de fixation 4 se présentent sous la forme de picots 5 avec une tête déformable 6, destinée à se déformer lors de son introduction dans un orifice prévu dans la structure du véhicule, puis à reprendre sa forme d'origine de sorte à réaliser un effet de harponnage. According to the embodiment shown, the fastening means 4 are in the form of pins 5 with a deformable head 6, intended to deform when introduced into an orifice provided in the vehicle structure, then to resume its original shape so as to achieve a harpooning effect.
Selon une réalisation, la feuille 3 est surmoulée par la coque 2. According to one embodiment, the sheet 3 is overmolded by the shell 2.
Selon une réalisation, la coque 2 est renforcée par des fibres, notamment de verre ou végétales. In one embodiment, the shell 2 is reinforced by fibers, in particular glass or vegetable fibers.
Selon une réalisation, la feuille 3 comprend une couche métallique, notamment en aluminium. La couche métallique peut être utilisée seule ou complexée avec un film de matière plastique. La feuille 3 peut présenter une épaisseur minimale de 50 microns. According to one embodiment, the sheet 3 comprises a metal layer, in particular of aluminum. The metal layer may be used alone or complexed with a plastic film. The sheet 3 can have a minimum thickness of 50 microns.
Selon une autre réalisation, la feuille 3 est à base d'un film de matière plastique, éventuellement multi couches, dont une couche peut être notamment à base de polyéthylène téréphtalate, ladite feuille étant chargé avec des particules métalliques, notamment d'aluminium. 5 3 On décrit à présent un procédé de réalisation d'un écran 1 selon une réalisation comprenant une étape de mise en place, dans le moule de moulage de la coque 2 et avant son moulage, d'une feuille 3 en métal préformée de sorte à la surmouler par ladite coque. According to another embodiment, the sheet 3 is based on a plastic film, optionally multi-layer, a layer may be in particular based on polyethylene terephthalate, said sheet being loaded with metal particles, including aluminum. A method of producing a screen 1 according to an embodiment comprising a step of placing, in the molding mold of the shell 2 and before its molding, a sheet 3 of preformed metal so as to be described, is now described. to overmould it by said shell.
Selon une réalisation, la feuille 3 en métal est préalablement gaufrée avant son formage, ceci afin d'éviter les déchirures. In one embodiment, the metal sheet 3 is previously embossed before forming, in order to prevent tearing.
