Description

DISPOSITIF D'ECLAIRAGE ET/OU DE SIGNALISATION LUMINEUSE COMPRENANT DES MOYENS DE FIXATION SUR UN VEHICULE AUTOMOBILE  LIGHTING AND / OR LIGHT-SIGNALING DEVICE COMPRISING FASTENING MEANS ON A MOTOR VEHICLE
[001 ] L'invention concerne, de façon générale, le domaine de la protection en cas de choc, en particulier dans le domaine des véhicules automobiles. [001] The invention relates, in general, the field of protection in case of impact, particularly in the field of motor vehicles.
[002] L'invention porte plus précisément sur un système de fixation d'un dispositif d'éclairage et/ou de signalisation lumineux sur un véhicule automobile. [002] The invention relates more specifically to a fixing system of a lighting device and / or light signaling on a motor vehicle.
[003] De manière connue, des dispositifs d'éclairage et/ou de signalisation lumineuse sont disposés à l'avant et à l'arrière d'un véhicule automobile afin, d'une part, d'éclairer la route pour améliorer la visibilité du conducteur du véhicule, notamment en condition nocturne, et, d'autre part, de signaliser la position du véhicule aux autres usagers de la route. [003] In known manner, lighting and / or light signaling devices are arranged at the front and rear of a motor vehicle to, on the one hand, to illuminate the road to improve visibility the driver of the vehicle, especially in night conditions, and, secondly, to signal the position of the vehicle to other road users.
[004] Un dispositif d'éclairage et/ou de signalisation lumineuse est fixé au niveau de l'aile avant du véhicule afin d'être placé à l'avant du véhicule. Cette fixation est dimensionnée de manière à répondre à des normes de sécurité, telles que la norme EuroNCAP, exigeant de limiter la résistance à l'avant du véhicule afin de limiter les dommages aussi bien sur le véhicule lui-même que sur son environnement. Ces normes comprennent notamment une exigence dite « choc piéton fémur » visant à limiter les dommages en cas de choc avec un piéton afin de protéger le piéton, ainsi qu'une exigence dite « choc réparabilité » visant à rendre le véhicule aisément réparable après un choc à une vitesse maximale de 16 km/h sur un mur rigide incliné de 10 ° et sur un recouvrement de 40% de la surface avant du véhicule. [004] A lighting and / or light signaling device is fixed at the front wing of the vehicle to be placed at the front of the vehicle. This attachment is sized to meet safety standards, such as the EuroNCAP standard, which requires limiting the resistance at the front of the vehicle to limit damage to both the vehicle itself and its environment. These standards include a so-called "femur foot impact" to limit damage in case of impact with a pedestrian to protect the pedestrian, and a requirement called "repairable shock" to make the vehicle easily repairable after a shock at a maximum speed of 16 km / h on a rigid wall inclined by 10 ° and a covering of 40% of the front surface of the vehicle.
[005] On connaît par le document FR 2895954, un dispositif d'éclairage et/ou de signalisation lumineuse avant fixé au véhicule à l'aide de trois vis : deux vis placées en partie supérieure du dispositif et une vis placée en partie inférieure. Cette fixation permet de répondre aux normes de résistance pour la majorité des véhicules. [005] Document FR 2895954 discloses a front lighting and / or light signaling device fastened to the vehicle by means of three screws: two screws placed in the upper part of the device and a screw placed in the lower part. This attachment allows to meet the standards of resistance for the majority of the vehicles.
[006] Cependant, dans le cas de certains véhicules automobiles, notamment des véhicules dont le gabarit est important, le poids plus important du véhicule oblige à réduire la résistance de la fixation pour éviter la dégradation de critères biomécaniques et ainsi répondre aux normes de sécurité. La fixation d'un dispositif par trois vis présente alors une résistance trop importante. [007] Aussi, il a été proposé de fixer le dispositif d'éclairage et/ou de signalisation lumineuse avant à l'aide de deux vis placées en partie supérieure et d'une fixation par crochet en partie inférieure. Cette fixation par crochet forme une butée permettant de maintenir le dispositif en place tout en permettant un déplacement de quelques millimètres afin de réduire la résistance de la fixation du dispositif et ainsi de répondre aux exigences de résistance en cas de choc. [006] However, in the case of certain motor vehicles, including vehicles whose size is important, the greater weight of the vehicle requires reducing the strength of the binding to avoid the degradation of biomechanical criteria and thus meet safety standards . Fixing a device with three screws then has too much resistance. [007] Also, it has been proposed to fix the lighting device and / or front light signaling by means of two screws placed in the upper part and a fixing hook in the lower part. This attachment hook forms a stop to maintain the device in place while allowing a displacement of a few millimeters to reduce the strength of the attachment of the device and thus meet the requirements of resistance in case of shock.
[008] Cependant, cette solution présente également des inconvénients. En effet, le dispositif d'éclairage et/ou de signalisation lumineuse avant étant simplement maintenu par un crochet au niveau de sa partie inférieure, le dispositif présente un degré de liberté au niveau du crochet. Un jeu se forme alors, au cours de la vie du véhicule, entre la partie inférieure du dispositif et l'aile du véhicule. La durée de vie du dispositif et la qualité perçue, notamment à cause d'un affaissement de la face avant du dispositif, s'en trouvent alors dégradées, ce qui représente un inconvénient majeur pour de tels véhicules. [008] However, this solution also has drawbacks. Indeed, the lighting device and / or front light signal is simply maintained by a hook at its lower part, the device has a degree of freedom at the hook. A game is then formed, during the life of the vehicle, between the lower part of the device and the wing of the vehicle. The life of the device and perceived quality, particularly because of a collapse of the front of the device, are then degraded, which represents a major drawback for such vehicles.
[009] L'invention vise donc à résoudre ces inconvénients en proposant un système de fixation d'un dispositif d'éclairage et/ou de signalisation lumineuse sur un véhicule automobile qui soit simple, fiable tout en répondant aux exigences de résistance et d'usure. [009] The invention therefore aims to solve these disadvantages by providing a system for fixing a lighting device and / or light signaling on a motor vehicle that is simple, reliable while meeting the requirements of resistance and wear.
[0010] Pour parvenir à ce résultat, la présente invention concerne un dispositif d'éclairage et/ou de signalisation lumineuse adapté pour être monté sur un véhicule automobile s'étendant longitudinalement selon un axe longitudinal, ledit dispositif d'éclairage et/ou de signalisation lumineuse comprenant un boîtier dans lequel au moins une source de lumière est adaptée pour être montée, des premiers moyens de fixation et des deuxièmes moyens de fixation, lesdits premiers moyens de fixation et lesdits deuxièmes moyens de fixation étant adaptés pour permettre la fixation dudit boîtier sur le véhicule automobile par vissage selon un axe vertical, les deuxièmes moyens de fixation comprenant un corps de fixation s'étendant en saillie du boîtier, ledit corps de fixation comprend une zone de striction de la section dudit corps de fixation adaptée pour permettre la rupture du corps de fixation lors d'un choc. To achieve this result, the present invention relates to a lighting device and / or light signaling adapted to be mounted on a motor vehicle extending longitudinally along a longitudinal axis, said lighting device and / or light signaling device comprising a housing in which at least one light source is adapted to be mounted, first fixing means and second fixing means, said first fixing means and said second fixing means being adapted to allow the attachment of said housing on the motor vehicle by screwing along a vertical axis, the second fixing means comprising a fixing body projecting from the housing, said fixing body comprises a necking zone of the section of said fastening body adapted to allow the rupture fixing body during an impact.
[001 1 ] Grâce au dispositif selon l'invention, le montage d'un dispositif d'éclairage et/ou de signalisation lumineuse sur un véhicule est aisé grâce au vissage des premiers et deuxièmes moyens de fixation qui permet un montage isostatique pour optimiser la qualité perçue. De plus, la zone de striction des deuxièmes moyens de fixation permet le déplacement de quelques millimètres du boîtier lors d'un choc sur le dispositif grâce à la rupture des deuxièmes moyens de fixation, ce qui permet de respecter les exigences « choc piéton fémur » et choc « réparabilité ». [001 1] With the device according to the invention, the mounting of a lighting device and / or light signaling on a vehicle is easy thanks to the screwing of the first and second fixing means which allows an isostatic mounting to optimize the perceived quality. In addition, the necking zone of the second fixing means allows the displacement of a few millimeters of the housing during an impact on the device thanks to the rupture of the second attachment means, which makes it possible to comply with the requirements of "femur shock" and "repairability" shock.
[0012] Avantageusement, le corps de fixation s'étendant selon l'axe longitudinal, la section dudit corps de fixation est définie dans un plan orthogonal à l'axe longitudinal. [0013] Avantageusement, le boîtier comprenant une partie supérieure et une partie inférieure, les premiers moyens de fixation sont situés au niveau de ladite partie supérieure afin de fixer la partie supérieure du boîtier sur le véhicule automobile et les deuxièmes moyens de fixation sont situés au niveau de ladite partie inférieure afin de fixer la partie inférieure du boîtier sur le véhicule automobile. [0014] Avantageusement, la zone de striction est dimensionnée de manière à permettre la rupture du corps de fixation lorsqu'une force supérieure à 60 daN est exercée selon l'axe longitudinal. Advantageously, the fastening body extending along the longitudinal axis, the section of said fastening body is defined in a plane orthogonal to the longitudinal axis. Advantageously, the housing comprising an upper portion and a lower portion, the first fastening means are located at said upper portion in order to fix the upper part of the housing on the motor vehicle and the second fastening means are located at level of said lower part to fix the lower part of the housing on the motor vehicle.

Advantageously, the necking zone is dimensioned so as to allow the breaking of the fastener body when a force greater than 30 daN is exerted along the vertical axis and / or when a force greater than 60 daN is exerted according to a transverse axis, the transverse axis being orthogonal to the longitudinal axis and the vertical axis.
[0016] Avantageusement, les deuxièmes moyens de fixation comprennent au moins une butée s'étendant en saillie du boîtier et selon l'axe longitudinal de manière à limiter le déplacement du boîtier après la rupture du corps de fixation à une valeur prédéterminée, de préférence 5 mm. Advantageously, the second fixing means comprise at least one stop extending projecting from the housing and along the longitudinal axis so as to limit the displacement of the housing after the breaking of the fixing body to a predetermined value, preferably 5 mm.

[0021 ] Dans ce qui va suivre, les modes de réalisation décrits s'attachent plus particulièrement à une mise en œuvre du dispositif selon l'invention au sein d'un véhicule automobile. Cependant, toute mise en œuvre dans un contexte différent, en particulier dans tout type de véhicule, est également visée par la présente invention. In what follows, the described embodiments focus more particularly on an implementation of the device according to the invention within a motor vehicle. However, any implementation in a different context, in particular in any type of vehicle, is also covered by the present invention.
[0022] Les figures 1 et 2 représentent un dispositif d'éclairage et/ou de signalisation lumineuse 100 monté sur la structure de support 200 d'un véhicule automobile (non représenté). Figures 1 and 2 show a lighting device and / or light signaling 100 mounted on the support structure 200 of a motor vehicle (not shown).
[0023] Dans la suite de la description, les termes « avant », « arrière », « gauche », « droite », « haut » et « bas » sont définis par rapport à un véhicule circulant vers l'avant sur une voie de circulation. Le véhicule automobile s'étend ainsi d'avant en arrière selon un axe longitudinal XX, de gauche à droite selon un axe transversal YY et de haut en bas selon un axe vertical ZZ. In the remainder of the description, the terms "front", "back", "left", "right", "up" and "down" are defined with respect to a vehicle traveling forwards on a track. of circulation. The motor vehicle thus extends back and forth along a longitudinal axis XX, from left to right along a transverse axis YY and from top to bottom along a vertical axis ZZ.
[0024] Dans cette forme de réalisation, le dispositif d'éclairage et/ou de signalisation lumineuse 100 est monté à l'avant du véhicule automobile afin d'émettre de la lumière vers l'avant du véhicule.

[0027] Le boîtier 10 comprend au moins une source de lumière (non représentée) et une paroi transparente (non représentée). La source de lumière est adaptée pour émettre de la lumière à travers la paroi transparente afin d'envoyer de la lumière hors du boîtier, notamment pour éclairer et/ou pour envoyer un signal lumineux. Lorsque le dispositif d'éclairage et/ou de signalisation lumineuse 100 est monté sur le véhicule, la paroi transparente permet de fermer le logement de montage du véhicule afin d'augmenter la qualité perçue de cet assemblage. The lighting and / or light signaling device 100 comprises a housing 10, first fastening means (not shown) and second fixing means 20 of the housing 10 on the motor vehicle. The housing 10 comprises at least one light source (not shown) and a transparent wall (not shown). The light source is adapted to emit light through the transparent wall in order to send light out of the housing, in particular to illuminate and / or to send a light signal.

Les deuxièmes moyens de fixation 20 comprennent un corps de fixation, également désigné « patte de fixation 21 », s'étendant en saillie de la partie inférieure du boîtier 10 et selon l'axe longitudinal XX comme illustré sur les figures 1 et 2. [0030] La patte de fixation 21 s'étend depuis le boîtier 10 jusqu'à une extrémité libre 22. La patte de fixation 21 comprend, au niveau de son extrémité libre 22, un orifice adapté pour être traversé par une vis 30 de fixation sur le véhicule. Ainsi, grâce aux deuxièmes moyens de fixation 20, les mouvements du boîtier 10 selon l'axe longitudinal XX, selon l'axe transversal YY et selon l'axe vertical ZZ sont bloqués. Cette vis 30 permet également d'éviter toute rotation du dispositif d'éclairage et/ou de signalisation lumineuse 100 par rapport au véhicule, notamment lors du roulage du véhicule sur une voie de circulation. The second fastening means 20 allow to fix the lower part of the housing 10 on the vehicle. The second fixing means 20 comprise a fastening body, also designated "fastening tab 21", projecting from the lower part of the casing 10 and along the longitudinal axis XX as illustrated in FIGS. 1 and 2. [ The fixing lug 21 extends from the housing 10 to a free end 22. The fixing lug 21 comprises, at its free end 22, an orifice adapted to be traversed by a fixing screw 30. the vehicle. Thus, thanks to the second fastening means 20, the movements of the housing 10 along the longitudinal axis XX along the transverse axis YY and along the vertical axis ZZ are blocked. This screw 30 also makes it possible to avoid any rotation of the lighting device and / or light signaling device 100 with respect to the vehicle, in particular when the vehicle is traveling on a traffic lane.
[0031 ] Le montage du dispositif d'éclairage et/ou de signalisation lumineuse 100 par trois vis 30 permet ainsi un montage isostatique du dispositif d'éclairage et/ou de signalisation lumineuse 100 sur le véhicule et permet d'optimiser la qualité perçue de ce montage durant la vie du véhicule. [0032] Afin de répondre aux différentes normes, les deuxièmes moyens de fixation 20 comprennent en outre une zone de striction adaptée pour permettre la rupture de la patte de fixation 21 lors d'un choc, et une butée 23. The mounting of the lighting device and / or light signaling 100 by three screws 30 allows an isostatic mounting of the lighting device and / or light signaling 100 on the vehicle and optimizes the perceived quality of this assembly during the life of the vehicle. In order to meet the different standards, the second fastening means 20 further comprise a necking zone adapted to allow the breaking of the fastening lug 21 during an impact, and a stop 23.
[0033] Entre le boîtier 10 et l'extrémité libre 22, la patte de fixation 21 comprend une zone de striction. Autrement dit, la section de la patte de fixation 21 , comprise dans un plan orthogonal à l'axe longitudinal XX, est réduite afin de permettre à la patte de fixation 21 de rompre en cas de choc. Autrement dit, les dimensions de la patte de fixation 21 sont réduites selon l'axe transversal YY et selon l'axe vertical ZZ. Cette zone de striction permet ainsi à la patte de fixation 21 d'être utilisée comme un fusible qui rompt en cas de choc afin de préserver le véhicule et son environnement. Between the housing 10 and the free end 22, the fastening lug 21 comprises a necking zone. In other words, the section of the fastening tab 21, in a plane orthogonal to the longitudinal axis XX, is reduced in order to allow the fastening lug 21 to break in the event of impact. In other words, the dimensions of the fixing lug 21 are reduced along the transverse axis YY and along the vertical axis ZZ. This necking zone thus allows the fixing lug 21 to be used as a fuse that breaks in the event of a shock in order to preserve the vehicle and its environment.
[0034] La zone de striction est ainsi dimensionnée pour chaque axe XX, YY, ZZ, selon la force maximale désirée avant la rupture de la patte de fixation 21 . Ainsi, lorsque le véhicule subit un choc, si une force est exercée selon un des axes XX, YY et/ou ZZ et est supérieure à la valeur de rupture de la patte de fixation 21 selon cet axe, la patte de fixation 21 rompt afin de réduire la résistance du véhicule et ainsi répondre aux normes de sécurité. Dans cet exemple, la zone de striction est dimensionnée de manière à résister jusqu'à une force de 60 daN exercée selon l'axe longitudinal XX, une force de 60 daN exercée selon l'axe transversal YY et/ou une force de 30 daN exercée selon l'axe vertical ZZ afin de respecter les exigences « choc piéton fémur » et « choc réparabilité » pour un choc du véhicule à une vitesse maximale de 16 km/h sur un mur rigide incliné de 10° et sur un recouvrement de 40% de la surface avant du véhicule. The necking zone is thus dimensioned for each axis XX, YY, ZZ, according to the desired maximum force before breaking of the fastening lug 21. Thus, when the vehicle is shocked, if a force is exerted along one of the axes XX, YY and / or ZZ and is greater than the value of rupture of the fastening lug 21 along this axis, the fastening lug 21 breaks to to reduce the resistance of the vehicle and thus meet safety standards. In this example, the necking zone is dimensioned so as to withstand a force of 60 daN exerted along the longitudinal axis XX, a force of 60 daN exerted along the transverse axis YY and / or a force of 30 daN exerted along the ZZ vertical axis in order to meet the requirements of "femur shock" and "shock repairability" for a vehicle impact at a maximum speed of 16 km / h on a rigid wall inclined by 10 ° and a lap of 40 % of the front surface of the vehicle.
[0035] La butée 23 s'étend en saillie du boîtier 10 et selon l'axe longitudinal XX. De préférence, la butée 23 s'étend en dessous de la patte de fixation 21 . La butée 23 est formée d'un muret comprenant une première face adaptée pour bloquer le mouvement selon l'axe longitudinal XX et une deuxième face adaptée pour bloquer le mouvement selon l'axe vertical ZZ. Lorsque la patte de fixation 21 rompt, le dispositif d'éclairage et/ou de signalisation lumineuse 100 peut se déplacer de quelques millimètres, de préférence jusqu'à 5 mm, selon l'axe longitudinal XX jusqu'à ce que la première face de la butée 23 vienne en appui contre le véhicule, notamment contre la structure de support 200 du véhicule. La butée 23 permet alors de bloquer le déplacement du dispositif d'éclairage et/ou de signalisation lumineuse 100 selon l'axe longitudinal XX, plus particulièrement le déplacement vers l'arrière. La butée 23 forme ainsi un muret anti-recul du boîtier 10. [0036] La butée 23 permet également de bloquer le déplacement du dispositif d'éclairage et/ou de signalisation lumineuse 100 selon l'axe vertical ZZ, plus particulièrement le déplacement vers le haut, lorsque la deuxième face de la butée 23 vient en appui contre le véhicule, notamment contre la structure de support 200 du véhicule. La butée 23 forme ainsi un muret anti-soulèvement du boîtier 10. The stop 23 extends projecting from the housing 10 and along the longitudinal axis XX. Preferably, the stop 23 extends below the fixing lug 21. The stop 23 is formed of a wall comprising a first face adapted to block the movement along the longitudinal axis XX and a second face adapted to block the movement along the vertical axis ZZ. When the fixing lug 21 breaks, the lighting and / or light-signaling device 100 can move a few millimeters, preferably up to 5 mm, along the longitudinal axis XX until the first face of the abutment 23 bears against the vehicle, in particular against the support structure 200 of the vehicle. The stop 23 then makes it possible to block the movement of the lighting and / or light-signaling device 100 along the longitudinal axis XX, more particularly the rearward movement. The abutment 23 thus forms an anti-recoil wall of the housing 10. The stop 23 also makes it possible to block the movement of the lighting device and / or light signaling device 100 along the vertical axis ZZ, more particularly the upward movement, when the second face of the stop 23 comes to bear. against the vehicle, in particular against the support structure 200 of the vehicle. The abutment 23 thus forms an anti-rising wall of the housing 10.
[0037] La butée 23 permet de prévenir le contact entre le dispositif d'éclairage et/ou de signalisation lumineuse 100 et un autre élément du véhicule, notamment un calculateur, tel que le BSM pour Boîtier de Servitude Moteur, afin de limiter les dégâts lors d'un choc. The stop 23 prevents the contact between the lighting and / or light signaling device 100 and another element of the vehicle, including a computer, such as the BSM for Motor Servitude Housing, to limit the damage during a shock.
[0038] Le dispositif d'éclairage et/ou de signalisation lumineuse 100 peut ainsi être fixé sur un véhicule automobile sans risque d'affaissement de sa face avant afin de maintenir la qualité perçue, tout en permettant un recul du dispositif 100 de quelques millimètres selon l'axe longitudinal XX en cas de choc grâce à la rupture de la patte de fixation 21 . Ceci permet de réduire la résistance du véhicule et ainsi respecter les exigences des normes lors d'un choc piéton fémur. De plus, grâce à la butée 23, le dispositif d'éclairage et/ou de signalisation lumineuse 100 est bloqué selon l'axe longitudinal XX et vertical ZZ, ce qui permet de respecter la norme de réparabilité lors d'un choc en maintenant le dispositif en place. The lighting and / or light signaling device 100 can thus be fixed on a motor vehicle without risk of sagging of its front face to maintain the perceived quality, while allowing a decline of the device 100 by a few millimeters along the longitudinal axis XX in case of impact due to the rupture of the fastening lug 21. This reduces the resistance of the vehicle and thus meet the requirements of standards during a femur pedestrian impact. In addition, thanks to the stop 23, the lighting and / or light signaling device 100 is blocked along the longitudinal axis XX and vertical ZZ, which makes it possible to respect the standard of repairability during an impact while maintaining the device in place.
