Description

L'invention est relative à un dispositif d'éclairage ou de signalisation pour véhicule automobile, du genre de ceux qui comportent un boîtier dans lequel est disposée au moins une source lumineuse, le boîtier comportant une paroi périphérique solidaire d'une paroi de fond, et étant ouvert sur une face frontale opposée à la paroi de fond, cette face frontale du boîtier étant fermée par une glace, fixée de manière permanente non démontable, en particulier par collage, au boîtier.The invention relates to a lighting or signaling device for a motor vehicle, of the type comprising a housing in which at least one light source is arranged, the housing comprising a peripheral wall integral with a bottom wall, and being open on a front face opposite to the bottom wall, this front face of the housing being closed by an ice, fixed permanently non-removable, in particular by gluing, to the housing.

L'invention concerne plus particulièrement, mais non exclusivement, un tel dispositif d'éclairage ou de signalisation dans lequel la source lumineuse est constituée d'au moins une diode électroluminescente, ou LED en abrégé.The invention relates more particularly, but not exclusively, to such a lighting or signaling device in which the light source consists of at least one light emitting diode, or LED for short.

L'invention concerne principalement un projecteur lumineux destiné à être monté à l'avant du véhicule, auquel cas la face frontale du boîtier est située à l'avant lorsque le projecteur est installé sur le véhicule. Toutefois, l'invention concerne également des dispositifs d'éclairage ou de signalisation qui peuvent être montés à l'arrière du véhicule, auquel cas la face frontale est tournée vers l'arrière lorsque le dispositif est installé sur le véhicule.The invention mainly relates to a light projector intended to be mounted at the front of the vehicle, in which case the front face of the housing is located at the front when the projector is installed on the vehicle. However, the invention also relates to lighting or signaling devices that can be mounted at the rear of the vehicle, in which case the front face is turned towards the rear when the device is installed on the vehicle.

Le boîtier d'un tel dispositif d'éclairage ou de signalisation, avec glace fixée de manière permanente, constitue un ensemble fermé empêchant, ou rendant difficile, le remplacement d'un élément défaillant à l'intérieur du boîtier. Une ouverture, fermée par un bouchon démontable, est fréquemment prévue dans la paroi de fond du boîtier, notamment pour le passage de conducteurs électriques, mais cet accès n'est pas suffisamment pratique pour le remplacement d'un élément défaillant, notamment un module à LED ou un circuit d'alimentation. Dans la pratique, la défaillance d'une source lumineuse ou d'un composant situé à l'intérieur du boîtier entraîne le remplacement de l'ensemble du dispositif d'éclairage ou de signalisation, ce qui est relativement coûteux.The housing of such a lighting or signaling device, with permanently attached ice, constitutes a closed assembly preventing, or making it difficult, the replacement of a defective element inside the housing. An opening, closed by a removable cap, is frequently provided in the bottom wall of the housing, especially for the passage of electrical conductors, but this access is not practical enough for the replacement of a defective element, including a module to LED or power circuit. In practice, the failure of a light source or component located inside the housing causes the replacement of the entire lighting or signaling device, which is relatively expensive.

Il est donc souhaitable de proposer un dispositif d'éclairage ou de signalisation du genre défini précédemment qui permette une réparation par remplacement d'un élément défaillant à l'intérieur du boîtier, et qui évite d'avoir à changer tout l'ensemble du dispositif. Il est également souhaitable que le dispositif ne soit pas rendu plus complexe ni plus coûteux.It is therefore desirable to provide a lighting or signaling device of the kind defined above which allows a repair by replacing a defective element inside the housing, and which avoids having to change the entire device . It is also desirable that the device is not made more complex or more expensive.

Selon l'invention, un dispositif d'éclairage ou de signalisation pour véhicule automobile, du genre en question, est caractérisé en ce que la paroi périphérique du boîtier et/ou de la glace comporte au moins une ligne sécable propre à être découpée pour permettre l'accès à l'intérieur d'une partie du boîtier comportant l'au moins une source lumineuse, pour le remplacement d'un élément défaillant.According to the invention, a lighting or signaling device for motor vehicle, of the kind in question, is characterized in that the peripheral wall of the housing and / or the ice has at least one breakable line clean to be cut to allow access to the inside of a portion of the housing comprising the at least one light source, for the replacement of a defective element.

Avantageusement, les bords de la ligne sécable sont prévus pour permettre, après découpe, la réunion des deux parties du boîtier par un raccord, notamment par un raccord annulaire.Advantageously, the edges of the breakable line are provided to allow, after cutting, the joining of the two parts of the housing by a connection, in particular by an annular connection.

De préférence, la paroi périphérique du boîtier comporte au moins deux lignes sécables espacées suivant la direction de l'axe géométrique du boîtier, s'étendant sur toute la périphérie, les bords des lignes sécables découpées étant prévus pour permettre, après découpe, la réunion des deux parties du boîtier par un raccord de forme quelconque , notamment de forme cylindrique, en particulier de forme cylindrique de révolution ayant un axe horizontal.Preferably, the peripheral wall of the housing comprises at least two breakable lines spaced in the direction of the geometric axis of the housing, extending over the entire periphery, the edges of the scored cut lines being provided to allow, after cutting, the meeting. two parts of the housing by a connection of any shape, in particular of cylindrical shape, in particular of cylindrical shape of revolution having a horizontal axis.

Avantageusement, le raccord est constitué par un anneau d'assemblage, et la dimension de cet anneau suivant la direction de l'axe géométrique de l'anneau est égale à la distance entre les deux lignes sécables de sorte qu'après réparation le boîtier présente le même encombrement qu'avant réparation.Advantageously, the connection is constituted by an assembly ring, and the dimension of this ring in the direction of the geometric axis of the ring is equal to the distance between the two breakable lines so that after repair the present housing the same footprint as before repair.

Le boîtier peut comporter, en saillie sur sa périphérie extérieure, au moins une patte pour fixation à la structure du véhicule.The housing may comprise, projecting on its outer periphery, at least one lug for attachment to the vehicle structure.

La ou les ligne(s) sécable(s) peuvent être situées du côté de la patte de fixation opposé à la glace, de sorte que la patte ou les patte(s) de fixation restent fixées à la partie du boîtier comportant la glace après découpe des lignes sécables.The breakable line (s) may be located on the side of the bracket opposite the ice, so that the tab or the bracket (s) remain fixed to the part of the housing comprising the ice after cutting breakable lines.

Selon une autre possibilité, la ou les ligne(s) sécable(s) sont situées du même côté que la glace par rapport à la patte de fixation, qui reste fixée à la partie arrière du boîtier lors de la découpe des lignes sécables.According to another possibility, the line (s) breakable (s) are located on the same side as the ice relative to the fixing lug, which remains attached to the rear portion of the housing during cutting breakable lines.

Selon encore une autre possibilité, la ou les ligne(s) sécable(s) sont situées de part et d'autre de la patte de fixation, et l'anneau d'assemblage est muni d'une ou plusieurs patte(s) de fixation.According to yet another possibility, the line or lines breakable (s) are located on either side of the bracket, and the assembly ring is provided with one or more tab (s) of fixation.

Avantageusement, l'une au moins des lignes sécables constitue une ligne d'affaiblissement de choc piéton.Advantageously, at least one of the breakable lines constitutes a pedestrian impact weakening line.

La paroi de boîtier est avantageusement réalisée en matière plastique, les lignes sécables venant de moulage.The housing wall is advantageously made of plastic material, the breakable lines coming from molding.

L'invention est également relative à un accessoire de réparation pour un dispositif d'éclairage ou de signalisation tel que défini précédemment, caractérisé en ce qu'il est constitué par une pièce annulaire de section transversale identique à celle du boîtier pour épouser le contour des portions sécables de la paroi de boîtier.The invention also relates to a repair accessory for a lighting or signaling device as defined above, characterized in that it is constituted by an annular piece of cross section identical to that of the housing to fit the contour of the breakable portions of the housing wall.

La pièce annulaire peut être rigide, de dimension axiale correspondant à la distance entre les lignes sécables de sorte que, après mise en place de la pièce annulaire et solidarisation des deux parties du boîtier, ce dernier retrouve sa dimension axiale initiale.The annular piece may be rigid, of axial dimension corresponding to the distance between the breakable lines so that, after placing the annular piece and securing the two parts of the housing, the latter returns to its initial axial dimension.

En variante, la pièce annulaire peut être souple, de dimension axiale supérieure à la distance entre les lignes sécables sans compression, et pouvant devenir égale à ladite distance avec compression.Alternatively, the annular piece may be flexible, of axial dimension greater than the distance between the uncompressed breakable lines, and may become equal to said distance with compression.

Avantageusement, les bords de la pièce annulaire comportent des rainures propres à recevoir les bords des parties séparées du boîtier, en particulier pour la réalisation d'un collage avec étanchéité.Advantageously, the edges of the annular piece have grooves adapted to receive the edges of the separate parts of the housing, in particular for the realization of a sealed bonding.

En variante, les bords séparés des lignes sécables et les bords de la pièce annulaire peuvent comporter des moyens d'encliquetage conjugués pour l'assemblage des deux parties séparées du boîtier.As a variant, the separated edges of the breakable lines and the edges of the annular piece may comprise conjugate latching means for assembling the two separate parts of the casing.

Les rainures des bords de la pièce annulaire peuvent comporter des moyens d'étanchéité en fond de rainure, notamment une garniture en matière élastomère ou équivalent.The grooves of the edges of the annular piece may comprise sealing means at the bottom of the groove, in particular a lining of elastomeric material or equivalent.

L'invention consiste également en un procédé de réparation d'un dispositif d'éclairage ou de signalisation tel que défini précédemment, procédé selon lequel, après avoir démonté le dispositif de son support dans le véhicule, on découpe les lignes sécables pour séparer le boîtier en deux parties, on effectue le remplacement de l'élément défaillant dans la partie de fond du boîtier, et on assemble de nouveau les deux parties du boîtier à l'aide d'un accessoire de réparation constitué par une pièce annulaire rigide de section transversale identique à celle du boîtier pour épouser le contour de la portion sécable de la paroi de boîtier, la dimension axiale de cette pièce étant égale à la distance entre les lignes sécables de sorte que, après réparation, le boîtier retrouve sa dimension axiale initiale.The invention also consists in a method of repairing a lighting or signaling device as defined above, the method according to which, after dismounting the device from its support in the vehicle, the breakable lines are cut to separate the housing. in two parts, the defective element is replaced in the bottom part of the housing, and the two parts of the housing are reassembled by means of a repair accessory constituted by a rigid annular piece of cross-section identical to that of the housing to match the contour of the breakable portion of the housing wall, the axial dimension of this part being equal to the distance between the breakable lines so that, after repair, the housing returns to its original axial dimension.
