Description
Domaine technique de l’inventionTechnical field of the invention
L’invention concerne les blocs optiques de véhicule qui assurent au moins une fonction photométrique.The invention relates to vehicle light units which provide at least one photometric function.
Etat de la techniqueState of the art
Certains véhicules, éventuellement de type automobile, comprennent au moins un bloc optique comprenant un boîtier logeant des pièces et équipements qui pour certains participent à des fonctions photométriques d’éclairage ou de signalisation, comme par exemple une fonction de nappe éclairante (ou « light veil »), une fonction de feu de jour (ou DRL (pour « Daytime running Light (or Lamp) » - signalisation lumineuse allumée automatiquement lorsque le véhicule est mis en fonctionnement pendant le jour)), une fonction d’indicateur de changement de direction (ou clignotant), ou une fonction de feu de position (ou veilleuse ou encore lanterne). Ce type de bloc optique est par exemple décrit dans le document brevet FR-B13008167.Certain vehicles, possibly of the automobile type, comprise at least one optical unit comprising a box housing parts and equipment which, for some, participate in photometric lighting or signaling functions, such as for example an illuminating sheet function (or "light veil "), a daytime running light function (or DRL (for "Daytime running Light (or Lamp)" - light signaling automatically switched on when the vehicle is put into operation during the day)), a direction change indicator function (or flashing), or a position light function (or pilot light or lantern). This type of optical unit is for example described in patent document FR-B13008167.
Les pièces ou équipements précité(e)s, auxquel(le)s on associe ci-après l’adjectif « optique », peuvent être des sources de photons (comme par exemple des diodes électroluminescentes (ou LEDs), des masques, des réflecteurs, des collimateurs, des lentilles, des miroirs, ou des guides de lumière (éventuellement plats), par exemple.The aforementioned parts or equipment, to which the adjective “optical” is associated below, can be sources of photons (such as light-emitting diodes (or LEDs), masks, reflectors , collimators, lenses, mirrors, or light guides (possibly flat), for example.
Dans certains blocs optiques, plusieurs éléments optiques doivent être positionnés précisément les uns par rapport aux autres dans leur boîtier afin qu’une fonction photométrique puisse être assurée. C’est par exemple parfois le cas d’un masque et d’au moins une source de photons installée sur la face avant d’une carte électronique dans au moins une zone située devant au moins une ouverture du masque afin de permettre le passage des photons pour qu’ils participent à une fonction photométrique.In some optical blocks, several optical elements must be positioned precisely relative to each other in their housing so that a photometric function can be ensured. This is for example sometimes the case of a mask and at least one photon source installed on the front face of an electronic card in at least one zone located in front of at least one opening of the mask in order to allow the passage of photons so that they participate in a photometric function.
Lorsque l’on veut disposer d’ouverture(s) et de zone(s) de grandes dimensions, on est contraint d’utiliser au moins une carte électronique d’encore plus grandes dimensions, et donc les solidarisations fixes du masque et de la carte électronique à au moins une paroi interne du boîtier se font de façons indépendantes via respectivement des éléments et/ou pièces de fixation dédié(e)s et pour certaines rapporté(e)s, afin que la position de chaque zone demeure inchangée par rapport à chaque ouverture correspondante du masque. Il en résulte une augmentation notable du nombre de pièces et/ou d’éléments devant être assemblé(e)s ou intégré(e)s dans le boîtier, ce qui rend complexes l’architecture interne, l’assemblage et la réalisation du moule de ce boîtier et donc contribue à rendre son bloc optique onéreux.When one wants to have opening(s) and zone(s) of large dimensions, one is forced to use at least one electronic card of even larger dimensions, and therefore the fixed connections of the mask and the electronic card to at least one internal wall of the case are made independently via respectively dedicated elements and/or fixing parts and for some attached parts, so that the position of each zone remains unchanged with respect to at each corresponding opening of the mask. This results in a significant increase in the number of parts and / or elements to be assembled or integrated into the housing, which makes the internal architecture, assembly and production of the mold complex. of this housing and therefore contributes to making its optical unit expensive.
Par ailleurs, plus les dimensions d’une ouverture de masque sont grandes, moins le masque est rigide et donc plus il est fragile et risque d’être endommagé, en particulier lors de l’assemblage de son bloc optique. Cet inconvénient est encore plus accentué lorsque le masque comprend plusieurs ouvertures.Furthermore, the larger the dimensions of a mask opening, the less rigid the mask and therefore the more fragile it is and risks being damaged, in particular when assembling its optical unit. This drawback is even more accentuated when the mask comprises several openings.
L’invention a donc notamment pour but d’améliorer la situation par une réduction notable du nombre de pièces et/ou d’éléments devant être assemblé(e)s ou intégré(e)s dans un boîtier de bloc optique.The aim of the invention is therefore in particular to improve the situation by a significant reduction in the number of parts and/or elements that have to be assembled or integrated into an optical unit housing.
Présentation de l’inventionPresentation of the invention
Elle propose notamment à cet effet un bloc optique destiné à équiper un véhicule et comprenant un boîtier logeant :It proposes in particular for this purpose an optical unit intended to equip a vehicle and comprising a housing housing:
- au moins une carte électronique comportant une face avant sur laquelle est installée dans au moins une zone au moins une source délivrant des photons, et- at least one electronic card comprising a front face on which is installed in at least one zone at least one source delivering photons, and
- un masque comportant une face arrière en regard de la carte électronique et au moins une ouverture située devant la (une) zone afin de permettre le passage des photons délivrés pour qu’ils participent à une fonction photométrique.- a mask comprising a rear face facing the electronic card and at least one opening located in front of the (one) zone in order to allow the passage of the photons delivered so that they participate in a photometric function.
Ce bloc optique se caractérise par le fait que son masque comprend au moins deux entretoises distantes, joignant deux bords opposés de l’ouverture et à chacune desquelles est couplée la carte électronique.This optical block is characterized by the fact that its mask comprises at least two spacers at a distance, joining two opposite edges of the opening and to each of which the electronic card is coupled.
On dispose ainsi d’un assemblage masque/carte(s) électronique(s) (avec source(s) de photons) notablement plus rigide et qui n’a plus qu’à être solidarisé au boîtier, ce qui permet de réduire notablement le nombre de pièces devant être assemblées ou intégrées dans le boîtier, et donc permet de réduire les complexités de l’architecture interne, de l’assemblage et des moules et le coût du bloc optique.This provides a mask/electronic card(s) assembly (with photon source(s)) that is significantly more rigid and which only has to be secured to the case, which makes it possible to significantly reduce the number of parts to be assembled or integrated into the housing, and therefore reduces the complexities of internal architecture, assembly and molds and the cost of the optical block.
Le bloc optique selon l’invention peut comporter d’autres caractéristiques qui peuvent être prises séparément ou en combinaison, et notamment :The optical block according to the invention may comprise other characteristics which may be taken separately or in combination, and in particular:

- il peut comprendre deux cartes électroniques installées l’une à la suite de l’autre et ayant des sources de photons situées devant deux sous-parties de chaque ouverture ;- it can include two electronic cards installed one after the other and having photon sources located in front of two sub-parts of each opening;
- chaque entretoise peut comprendre un premier élément de clippage coopérant avec un deuxième élément de clippage que comprend la carte électronique correspondante afin de solidariser fixement cette dernière au masque ;- each spacer can comprise a first clipping element cooperating with a second clipping element that comprises the corresponding electronic card in order to secure the latter fixedly to the mask;
- en présence de la dernière option, chaque premier élément de clippage peut être agencé sous la forme d’une patte de clippage traversant un trou traversant définissant un deuxième élément de clippage de la (d’une) carte électronique correspondante et comportant une tête de clippage s’appuyant sur une face arrière de cette carte électronique opposée à sa face avant ;- in the presence of the last option, each first clipping element can be arranged in the form of a clipping lug passing through a through hole defining a second clipping element of the (of a) corresponding electronic card and comprising a head of clipping based on a rear face of this electronic card opposite its front face;
- la face arrière du masque peut comprendre au moins un élément de fixation auquel est fixé au moins un câble électrique couplé à une carte électronique ;- the rear face of the mask may comprise at least one fixing element to which is fixed at least one electrical cable coupled to an electronic card;
- en présence de la dernière option, chaque élément de fixation peut être agencé sous la forme d’une lyre ;- in the presence of the last option, each fastening element can be arranged in the form of a lyre;
- également en présence de la dernière option, la face arrière du masque peut comprendre au moins une nervure dans laquelle est défini un élément de fixation ;- also in the presence of the last option, the rear face of the mask may comprise at least one rib in which a fastening element is defined;
- le masque peut être solidarisé fixement au boîtier.- the mask can be fixedly attached to the case.
L’invention propose également un véhicule, éventuellement de type automobile, et comprenant au moins un bloc optique du type de celui présenté ci-avant.The invention also proposes a vehicle, optionally of the automotive type, and comprising at least one optical unit of the type presented above.
