DESCRIPTION DESCRIPTION
Titre : DISPOSITIF DE FIXATION D’UN BOITIER ELECTRIQUE DANS UNTitle: DEVICE FOR FIXING AN ELECTRICAL BOX IN A
VEHICULE AUTOMOBILE MOTOR VEHICLE
La présente invention revendique la priorité de la demande française N°2101501 déposée le 17.02.2021 dont le contenu (texte, dessins et revendications) est ici incorporé par référence. The present invention claims the priority of French application No. 2101501 filed on 02.17.2021, the content of which (text, drawings and claims) is incorporated herein by reference.
La présente invention concerne un dispositif de fixation d’un boîtier électrique dans un compartiment moteur de véhicule automobile, ainsi qu’un véhicule automobile équipé d’un tel dispositif de fixation. The present invention relates to a device for fixing an electrical box in a motor vehicle engine compartment, as well as a motor vehicle equipped with such a fixing device.
Les véhicules automobiles peuvent comporter dans le compartiment moteur à l’avant du véhicule des boîtiers électriques devant rester facilement accessibles, par exemple un boîtier contenant des fusibles disposés sur les différents faisceaux électriques de manière à les protéger. En particulier le boîtier électrique peut être fixé vers le haut du compartiment moteur, entre la façade avant et la batterie du réseau de bord au-dessus de la boîte de vitesses, en avant du tablier disposé devant le conducteur. De cette manière le boîtier électrique reste comme la batterie facilement accessible, pour permettre des interventions comme un changement de fusible dans le cas d’un boîtier de fusibles. Motor vehicles may have electrical boxes in the engine compartment at the front of the vehicle that must remain easily accessible, for example a box containing fuses arranged on the various electrical harnesses so as to protect them. In particular, the electrical box can be fixed to the top of the engine compartment, between the front facade and the on-board network battery above the gearbox, in front of the bulkhead placed in front of the driver. In this way, the electrical box remains easily accessible like the battery, to allow interventions such as changing the fuse in the case of a fuse box.
De plus le boîtier électrique disposé en partie haute du compartiment moteur, est mieux à l’abri des projections d’eau pour protéger les circuits électriques. En particulier il est connu de prévoir un support du boîtier électrique formé par un moulage en matière plastique, qui est fixé directement sur des éléments porteurs fixes par différents calages dans le plan horizontal, et par un appui inférieur auquel s’ajoute au moins une vis venant maintenir cet appui vertical. Le boîtier électrique vient ensuite se fixer dans un logement du support. In addition, the electrical box located in the upper part of the engine compartment is better protected from splashing water to protect the electrical circuits. In particular, it is known to provide a support for the electrical box formed by a molding of plastic material, which is fixed directly to fixed bearing elements by various wedgings in the horizontal plane, and by a lower support to which is added at least one screw. coming to maintain this vertical support. The electrical box is then fixed in a housing of the support.
Toutefois ce type de fixation du support comportant des vis, oblige à prévoir un accès à ces vis occupant un volume, et nécessite un temps d’intervention avec un outil pour le montage des vis lors de l’assemblage du véhicule ou le démontage en cas d’intervention en service après-vente, ce qui augmente les coûts. However, this type of fixing of the support comprising screws, makes it necessary to provide access to these screws occupying a volume, and requires intervention time with a tool for mounting the screws during assembly of the vehicle or the dismantling in the event of after-sales service intervention, which increases costs.
La présente invention a notamment pour but d’éviter ces problèmes de l’art antérieur. Elle propose à cet effet un dispositif de fixation d'un boîtier électrique dans un compartiment moteur de véhicule automobile, ce dispositif comportant des éléments porteurs fixes du véhicule, et un support comprenant deux rainures ouvertes vers le bas suivant une direction appelée verticale, chaque rainure recevant une forme complémentaire plate des éléments porteurs, ce dispositif étant remarquable en ce qu’une des rainures comporte sur un côté un clip de fixation automatique en fin de descente sur la forme complémentaire plate s’insérant dans cette rainure. The object of the present invention is in particular to avoid these problems of the prior art. It proposes for this purpose a device for fixing an electrical box in a motor vehicle engine compartment, this device comprising fixed supporting elements of the vehicle, and a support comprising two grooves open downwards in a direction called vertical, each groove receiving a complementary flat shape of the supporting elements, this device being remarkable in that one of the grooves comprises on one side an automatic fixing clip at the end of the descent on the flat complementary shape fitting into this groove.
Un avantage de ce dispositif de fixation est que par un mouvement simple et sans outillage, un opérateur peut descendre le support de manière à entrer simultanément les deux formes plates dans les deux rainures, jusqu’à la fin de descente au fonds des rainures où le clipsage s’applique automatiquement pour maintenir le support dans cette position. An advantage of this fixing device is that by a simple movement and without tools, an operator can lower the support so as to simultaneously enter the two flat shapes in the two grooves, until the end of the descent to the bottom of the grooves where the clipping is automatically applied to maintain the support in this position.
On obtient un calage automatique du support dans les deux directions du plan horizontal, et dans la position verticale en fin de descente avec le clipsage de manière à positionner et fixer entièrement ce support dans toutes les directions. We obtain an automatic wedging of the support in the two directions of the horizontal plane, and in the vertical position at the end of the descent with the clipping so as to position and fix this support completely in all directions.
Le dispositif de fixation selon l’invention peut comporter de plus une ou plusieurs des caractéristiques suivantes, qui peuvent être combinées entre elles. Avantageusement, les deux rainures présentent des directions formant entre elles un angle sensiblement de 90°. The fixing device according to the invention may further comprise one or more of the following characteristics, which may be combined with one another. Advantageously, the two grooves have directions forming between them an angle of substantially 90°.
Avantageusement, chaque rainure comporte un système de blocage sur la forme complémentaire s’insérant dedans, qui bloque cette forme suivant la direction de la rainure. Dans ce cas, une forme complémentaire plate peut comporter sur un côté une nervure perpendiculaire, la rainure venant sur cette forme complémentaire, disposant sur un côté d’une fente ouverte vers le bas qui reçoit lors de la descente du support la nervure perpendiculaire pour réaliser le blocage suivant la direction de cette rainure. Advantageously, each groove includes a locking system on the complementary shape fitting into it, which blocks this shape in the direction of the groove. In this case, a flat complementary shape can comprise on one side a perpendicular rib, the groove coming on this complementary shape, disposing on one side of a slot open downwards which receives during the descent of the support the perpendicular rib to achieve the blocking in the direction of this groove.
En complément, une forme complémentaire plate peut comporter sur son bord supérieur une fente recevant un bossage disposé au fond de la rainure s’ajustant dessus, pour réaliser le blocage suivant la direction de cette rainure. In addition, a flat complementary shape may comprise on its upper edge a slot receiving a boss arranged at the bottom of the groove fitting above, to achieve blocking in the direction of this groove.
Avantageusement, une rainure comporte sur une face tournée vers la forme complémentaire plate s’insérant dedans, un clip de verrouillage venant en fin de descente du support en dessous de cette forme complémentaire. Advantageously, a groove comprises on a face facing the flat complementary shape fitting into it, a locking clip coming at the end of the descent of the support below this complementary shape.
Dans ce cas, avantageusement la rainure comporte au dos de la paroi portant le clip de verrouillage, un creux qui est ouvert vers le haut. In this case, advantageously the groove comprises on the back of the wall bearing the locking clip, a hollow which is open upwards.
L’invention a aussi pour objet un procédé de dépose d’un dispositif de fixation comprenant une rainure avec le creux au dos de la paroi, comportant une étape de descente d’un outil allongé dans le creux, puis une étape de basculement de cet outil pour éloigner le clip de verrouillage de la forme complémentaire plate. The invention also relates to a method for removing a fastening device comprising a groove with the hollow on the back of the wall, comprising a step of lowering an elongated tool into the hollow, then a step of tilting this tool to push the locking clip away from the flat complementary shape.
L’invention a de plus pour objet un véhicule automobile comportant un boîtier électrique fixé dans le compartiment moteur, maintenu par un dispositif de fixation comprenant l’une quelconque des caractéristiques précédentes.The invention further relates to a motor vehicle comprising an electrical box fixed in the engine compartment, held by a fixing device comprising any one of the preceding characteristics.
En particulier le boîtier électrique comportant des fusibles, peut être disposé suivant la direction longitudinale du véhicule entre une face avant du compartiment moteur et un bac recevant la batterie du réseau de bord. L’invention sera mieux comprise et d’autres caractéristiques et avantages apparaîtront plus clairement à la lecture de la description ci-après donnée à titre d’exemple, en référence aux dessins annexés dans lesquels : In particular, the electrical box comprising fuses can be arranged along the longitudinal direction of the vehicle between a front face of the engine compartment and a tray receiving the battery from the on-board network. The invention will be better understood and other characteristics and advantages will appear more clearly on reading the description below given by way of example, with reference to the appended drawings in which:
[Fig. 1] présente une vue d’ensemble du compartiment moteur avant d’un véhicule automobile équipé d’un dispositif de fixation d’un boîtier électrique selon l’invention ; [Fig. 1] presents an overall view of the front engine compartment of a motor vehicle equipped with a device for fixing an electrical box according to the invention;
[Fig. 2] est une vue de dessus du boîtier électrique fixé sur son support de ce véhicule ; [Fig. 2] is a top view of the electrical box fixed to its support of this vehicle;
[Fig. 3] est une vue de dessus du support mis en place sans le boîtier électrique ; [Fig. 3] is a top view of the support installed without the electrical box;
[Fig. 4] est une vue de dessous du support ; et [Fig. 5] est une vue en coupe longitudinale présentant le détachement de ce support. [Fig. 4] is a bottom view of the support; and [Fig. 5] is a view in longitudinal section showing the detachment of this support.
La figure 1 présente un compartiment moteur d’un véhicule automobile présentant une direction longitudinale avant indiquée par la flèche AV, comportant une façade avant 2 formant un cadre réalisé par un moulage de matière plastique, qui est disposé suivant la direction transversale du véhicule. Figure 1 shows an engine compartment of a motor vehicle having a front longitudinal direction indicated by the arrow AV, comprising a front facade 2 forming a frame made by molding plastic material, which is arranged in the transverse direction of the vehicle.
Une batterie du réseau de bord 4 est fixée en partie supérieure du compartiment moteur sur le côté gauche du véhicule, en avant d’un maître- cylindre de frein 6 fixé sur le tablier de la caisse de ce véhicule. An on-board electrical system battery 4 is fixed in the upper part of the engine compartment on the left side of the vehicle, in front of a brake master cylinder 6 fixed to the bulkhead of the body of this vehicle.
Un boîtier de fusibles 8 présentant une forme parallélépipédique allongée suivant la direction longitudinale, est maintenu dans un support 10 fixé en partie supérieure de la façade avant 2, entre cette façade et la batterie 4. De cette manière le boîtier de fusibles 8 est facilement accessible après avoir ouvert le capot moteur. A fuse box 8 having an elongated parallelepipedal shape in the longitudinal direction, is held in a support 10 fixed to the upper part of the front facade 2, between this facade and the battery 4. In this way the fuse box 8 is easily accessible after opening the bonnet.
La figure 2 présente le boîtier de fusibles 8 comportant un couvercle 14 fixé sur un fond 12 par un clip de fermeture 16, qui est ajusté dans un logement du support 10 réalisé par un moulage de matière plastique, entouré par une bordure 32 aux quatre angles permettant de maintenir ce boîtier à l’intérieur. La figure 3 présente la façade avant 2 comportant en partie supérieure sur le côté gauche, en arrière de cette façade, une cloison horizontale 20 comportant sur son côté droit une cloison verticale plate 24, qui reçoit en dessous un boîtier intermédiaire sensiblement parallélépipédique 22 formant une pièce porteuse. La cloison verticale 24 est reliée à la cloison horizontale 20 par deux nervures d’extrémité 26 et une nervure intermédiaire 28, formant des triangles perpendiculaires à ces cloisons permettant de les lier rigidement entre elles. Figure 2 shows the fuse box 8 comprising a cover 14 fixed to a bottom 12 by a closing clip 16, which is fitted in a housing of the support 10 made by molding plastic material, surrounded by a border 32 at the four corners to keep this box inside. FIG. 3 shows the front facade 2 comprising in the upper part on the left side, behind this facade, a horizontal partition 20 comprising on its right side a flat vertical partition 24, which receives below a substantially parallelepipedic intermediate box 22 forming a supporting part. The vertical partition 24 is connected to the horizontal partition 20 by two end ribs 26 and an intermediate rib 28, forming triangles perpendicular to these partitions allowing them to be rigidly linked together.
Le logement du support 10 comporte un fond plat recevant le boîtier électrique 8 représenté en pointillés sur cette figure. The housing of the support 10 comprises a flat bottom receiving the electrical box 8 shown in dotted lines in this figure.
Le support 10 comporte un plan supérieur vertical posé à plat sur la face de la cloison verticale 24 tournée vers l’intérieur du véhicule, qui comporte en haut un crochet de fixation comprenant une rainure supérieure 36 ouverte vers le bas, venant au-dessus du bord supérieur de cette cloison. Le côté de la rainure tourné vers l’extérieur du véhicule, comporte une fente en « V » formant un angle d’environ 90° ouvert vers le bas. The support 10 comprises a vertical upper plane laid flat on the face of the vertical partition 24 facing the interior of the vehicle, which comprises at the top a fixing hook comprising an upper groove 36 open downwards, coming above the upper edge of this partition. The side of the groove facing the outside of the vehicle has a “V” shaped slot forming an angle of approximately 90° open downwards.
Lors de la descente verticale du support 10 pour le fixer sur la façade avant 2, le bord supérieur de la cloison verticale 24 s’ajuste dans la rainure 36, puis la nervure intermédiaire triangulaire 28 rentre facilement dans la fente en « V » grâce à l’angle ouvert de cette fente, et en fin de descente s’ajuste au fond de cette fente. During the vertical descent of the support 10 to fix it on the front facade 2, the upper edge of the vertical partition 24 fits into the groove 36, then the triangular intermediate rib 28 fits easily into the "V" slot thanks to the open angle of this slot, and at the end of the descent adjusts to the bottom of this slot.
De cette manière on réalise un positionnement précis de la partie supérieure du support 10 qui est calé dans la direction transversale par un ajustement de la cloison verticale 24 dans la rainure supérieure 36, dans la hauteur par un ajustement du bord de la cloison au fond de cette rainure, et dans la direction longitudinale par un ajustement de la nervure intermédiaire 28 dans la fente du côté de la rainure. Les figures 3, 4 et 5 présentent la face transversale arrière 40 du boîtier intermédiaire 22 qui se prolonge par une patte plate dans un plan vertical 42, tournée vers l’intérieur du véhicule, comportant sur son bord supérieur une fente en « V » formant un angle d’environ 90° ouvert vers le haut. In this way, a precise positioning of the upper part of the support 10 is achieved, which is wedged in the transverse direction by an adjustment of the vertical partition 24 in the upper groove 36, in the height by an adjustment of the edge of the partition at the bottom of this groove, and in the longitudinal direction by an adjustment of the intermediate rib 28 in the slot on the side of the groove. Figures 3, 4 and 5 show the rear transverse face 40 of the intermediate casing 22 which is extended by a flat tab in a vertical plane 42, facing the interior of the vehicle, comprising on its upper edge a "V" shaped slot forming an angle of approximately 90° open upwards.
La partie inférieure du support 10 comporte une rainure inférieure de fixation 44 ouverte vers le bas, entourée par une partie arrière 48 qui descend en dessous de la patte verticale 42, et une partie avant 46 plus courte. The lower part of the support 10 comprises a lower fixing groove 44 open downwards, surrounded by a rear part 48 which descends below the vertical leg 42, and a shorter front part 46.
Lors de la descente du support 10 la patte verticale 42 du boîtier intermédiaire 22 entre dans la rainure inférieure 44 entre sa partie avant 46 et sa partie arrière 48, puis sa fente en « V » reçoit un bossage disposé au fond de cette rainure. De cette manière on réalise un positionnement précis de la partie inférieure du support 10 dans la direction longitudinale par un ajustement dans la rainure inférieure 44, et dans la direction transversale par un ajustement dans la fente de la patte verticale 42. When the support 10 is lowered, the vertical tab 42 of the intermediate casing 22 enters the lower groove 44 between its front part 46 and its rear part 48, then its “V” slot receives a boss arranged at the bottom of this groove. In this way, a precise positioning of the lower part of the support 10 is achieved in the longitudinal direction by an adjustment in the lower groove 44, and in the transverse direction by an adjustment in the slot of the vertical tab 42.
La partie arrière 48 de la rainure inférieure 44 comporte sur sa face avant vers le bas, un clip 50 comprenant une pente inférieure d’engagement qui glisse sur la patte verticale 42, et une face supérieure horizontale qui en fin de descente du support 10 vient par rappel élastique s’ajuster sous le bord inférieur de cette patte. De cette manière on réalise un verrouillage vers le haut de la rainure inférieure 44. The rear part 48 of the lower groove 44 comprises on its downward front face, a clip 50 comprising a lower engagement slope which slides on the vertical leg 42, and a horizontal upper face which at the end of the descent of the support 10 comes by elastic return adjust under the edge bottom of this leg. In this way, an upward locking of the lower groove 44 is achieved.
Les figures 4 et 5 présentent la partie arrière 48 de la rainure inférieure 44 formé par une paroi en matière plastique d’épaisseur fine réalisant un bossage descendant en dessous de la patte verticale 42, qui comporte dans ce bossage un creux ouvert vers le haut 52. Figures 4 and 5 show the rear part 48 of the lower groove 44 formed by a wall of thin plastic material forming a boss descending below the vertical leg 42, which comprises in this boss a hollow open upwards 52 .
Pour le retrait du clip 50 lors d’opérations de maintenance, un opérateur introduit par le haut un tournevis 60 qui descend dans le creux 52 de la partie arrière 48 de la rainure inférieure 44, puis le bascule comme indiqué par la flèche B, pour écarter vers l’arrière par déformation élastique le bas de cette partie. De cette manière on déplace vers l’arrière le clip 50 pour le dégager du dessous de la patte horizontale 42, ce qui permet ensuite à l’opérateur de tirer vers le haut le boîtier 10 pour le retirer du véhicule. To remove the clip 50 during maintenance operations, an operator introduces a screwdriver 60 from above which descends into the hollow 52 of the rear part 48 of the lower groove 44, then tilts it as indicated by the arrow B, to separating the bottom of this part backwards by elastic deformation. In this way, the clip 50 is moved backwards to disengage it from below the horizontal tab 42, which then allows the operator to pull the box 10 upwards to remove it from the vehicle.
