Description

Pièce d’assemblage pour connecter une planche de bord à une partie de caisse d’un véhicule Assembly part for connecting a dashboard to a body part of a vehicle
Domaine technique Technical area
[0001] La présente divulgation concerne une pièce d’assemblage pour connecter une planche de bord à une partie de caisse d’un véhicule. [0001] The present disclosure relates to an assembly part for connecting a dashboard to a body part of a vehicle.
Technique antérieure Prior art
[0002] Il est connu des pièces permettant d’assembler deux éléments constitutifs d’un véhicule, tel que par exemple, des pièces d’assemblage pour connecter une planche de bord à la caisse d’un véhicule. Toutefois, les solutions existantes ne permettent pas un ajustement précis des pièces entre-elles, ce qui entraîne des jeux de montage entre les pièces. Les jeux de montage sont particulièrement indésirables, en raison des vibrations et du bruit qu’ils engendrent. Par ailleurs, les pièces d’assemblages existantes ne permettent pas d’assembler facilement les éléments entre-eux et de les désassembler facilement une fois montés dans le véhicule. [0002] Parts are known for assembling two components of a vehicle, such as, for example, assembly parts for connecting a dashboard to the body of a vehicle. However, the existing solutions do not allow precise adjustment of the parts to one another, which leads to assembly clearances between the parts. Mounting clearances are particularly undesirable because of the vibrations and noise they generate. Furthermore, the existing assembly parts do not allow the elements to be easily assembled together and easily disassembled once mounted in the vehicle.
Résumé summary
[0003] La présente divulgation vient améliorer la situation. The present disclosure improves the situation.
[0004] Il est proposé une pièce d’assemblage pour connecter une planche de bord à une partie de caisse d’un véhicule, la pièce d’assemblage comprenant : une première partie mâle apte à venir en prise avec la planche de bord, et une deuxième partie femelle apte à venir en prise avec la partie de caisse du véhicule par un mouvement de rapprochement entre ladite partie femelle et ladite partie de caisse, ledit mouvement de rapprochement étant unidirectionnel et ajustable, la partie mâle étant sensiblement plate et s’étendant selon une direction longitudinale depuis une première extrémité en contact avec la partie femelle jusqu’à une deuxième extrémité libre en forme de crochet, la partie mâle et/ou la partie femelle étant configurées pour empêcher un mouvement de translation entre la planche de bord et la partie de caisse lorsque la partie mâle est en prise avec la planche de bord et la partie femelle est en prise avec la partie de caisse. [0005] Ainsi, la connexion entre la partie femelle et la partie de caisse n’est ajustable que dans le sens de rapprochement. Il n’est en outre pas possible d’écarter la pièce d’assemblage et la partie de caisse l’une de l’autre. Cela permet de réduire au maximum le jeu de connexion entre la planche de bord et la caisse de véhicule et les vibrations de la planche de bord lorsque le véhicule est en mouvement. An assembly part is proposed for connecting a dashboard to a body part of a vehicle, the assembly part comprising: a first male part adapted to engage with the dashboard, and a second female part adapted to come into engagement with the body part of the vehicle by an approximation movement between said female part and said body part, said approximation movement being unidirectional and adjustable, the male part being substantially flat and extending in a longitudinal direction from a first end in contact with the female part to a second free end in the form of a hook, the male part and / or the female part being configured to prevent a translational movement between the dashboard and the body part when the male part is engaged with the dashboard and the female part is engaged with the body part. [0005] Thus, the connection between the female part and the body part can only be adjusted in the direction of approach. It is also not possible to separate the assembly part and the body part from each other. This makes it possible to minimize the connection play between the dashboard and the vehicle body and the vibrations of the dashboard when the vehicle is in motion.
[0006] La pièce d’assemblage peut en outre comprendre deux parois latérales agencées de part et d’autre de la partie mâle pour empêcher un mouvement de translation entre la pièce d’assemblage et la planche de bord, et dans laquelle la partie mâle comprend deux bords latéraux rejoignant chacun la première extrémité de la partie mâle à la deuxième extrémité de la partie mâle, chacun des bords comprenant une protubérance, et les parois latérales comprennent chacune une ouverture coopérant avec respectivement une protubérance de la partie mâle pour limiter le mouvement de la deuxième extrémité de la partie mâle par rapport aux parois latérales. [0006] The assembly part may further comprise two side walls arranged on either side of the male part to prevent a translational movement between the assembly part and the dashboard, and in which the male part comprises two side edges each joining the first end of the male part to the second end of the male part, each of the edges comprising a protuberance, and the side walls each comprise an opening cooperating respectively with a protuberance of the male part to limit movement of the second end of the male part relative to the side walls.
[0007] La deuxième extrémité de la partie mâle peut en outre être mobile sensiblement perpendiculairement à un plan moyen de ladite partie mâle. [0007] The second end of the male part can also be movable substantially perpendicularly to a mean plane of said male part.
[0008] En outre, les parois latérales peuvent être disposées selon un plan perpendiculaire à la partie mâle et s’étendre chacune depuis la partie femelle jusqu’à une extrémité libre de paroi latérale, et la deuxième extrémité de la partie mâle et l’extrémité libre de paroi latérale peuvent former des surfaces de butée en regard délimitant un espace apte à recevoir une partie de la planche de bord pour bloquer la planche de bord en translation selon la direction longitudinale par rapport à la pièce d’assemblage. [0008] In addition, the side walls can be arranged in a plane perpendicular to the male part and each extend from the female part to a free end of the side wall, and the second end of the male part and the free end of the side wall can form facing abutment surfaces delimiting a space suitable for receiving a part of the dashboard in order to block the dashboard in translation in the longitudinal direction relative to the assembly part.
[0009] La partie femelle peut également comprendre une base et deux branches sensiblement perpendiculaires à la base, les branches et la base délimitant un espace pour recevoir la partie de caisse. En outre, l’une au moins des deux branches peut comprendre une zone dentée apte à coopérer avec une zone dentée de la partie de caisse pour empêcher un mouvement de translation entre la pièce d’assemblage et la partie de caisse dans la direction opposée du mouvement de rapprochement. [0010] Par ailleurs, l’une des deux branches peut comprendre une partie d’appui prévue pour être en appui sur la partie de caisse. The female part can also include a base and two branches substantially perpendicular to the base, the branches and the base defining a space for receiving the body part. In addition, at least one of the two branches may include a toothed zone adapted to cooperate with a toothed zone of the body part to prevent a translational movement between the assembly part and the body part in the opposite direction of the body. movement of rapprochement. [0010] Furthermore, one of the two branches may include a support part intended to be supported on the body part.
[0011] Alternativement ou au surplus, la pièce d’assemblage peut comprendre une butée élastique pour maintenir la partie mâle en prise avec la planche de bord, la butée élastique étant agencée sur la partie mâle ou sur la planche de bord et mettant en contact respectivement avec la planche de bord ou la partie mâle. [0011] Alternatively or in addition, the assembly part may comprise an elastic stopper to keep the male part in engagement with the dashboard, the elastic stopper being arranged on the male part or on the dashboard and putting in contact respectively with the dashboard or the male part.
[0012] La présente invention concerne également un ensemble comprenant une partie de caisse de véhicule et une pièce d’assemblage telle que décrite précédemment. The present invention also relates to an assembly comprising a vehicle body part and an assembly part as described above.
[0013] L’invention concerne en outre un véhicule comprenant une pièce d’assemblage telle que décrite précédemment, une planche de bord et une partie de caisse, la pièce d’assemblage connectant la planche de bord à la partie de caisse. [0013] The invention further relates to a vehicle comprising an assembly part as described above, an instrument panel and a body part, the assembly part connecting the dashboard to the body part.

Description des modes de réalisation [0020] La figure 1 illustre la pièce d’assemblage 10. La pièce d’assemblage 10 connecte la planche de bord 12 d’une part, à une partie de caisse 14 d’autre part. Comme ceci est illustré en perspective à la figure 2, la pièce d’assemblage 10 comprend une partie mâle 16 et une partie femelle 15. Pour l’assemblage de la planche de bord 12 avec la partie de caisse 14, la pièce d’assemblage 10 est d’abord clippée sur la planche de bord 12, puis l’ensemble formé par la pièce d’assemblage 10 et la planche de bord 12 est fixé sur la partie de caisse 14. Plus précisément, la pièce d’assemblage 10 est clippée sur la planche de bord 12 par la partie mâle 16 et l’ensemble formé par la pièce d’assemblage 10 et la planche de bord 12 est fixé sur la partie de caisse 14 par la partie femelle 15. La partie de caisse 14 peut être la caisse en elle-même ou une pièce rapportée fixée sur la caisse, par exemple soudée ou clippée sur la caisse. Description of the embodiments Figure 1 illustrates the assembly part 10. The assembly part 10 connects the dashboard 12 on the one hand, to a body part 14 on the other hand. As illustrated in perspective in FIG. 2, the assembly part 10 comprises a male part 16 and a female part 15. For the assembly of the dashboard 12 with the body part 14, the assembly part 10 is first clipped onto the dashboard 12, then the assembly formed by the assembly part 10 and the dashboard 12 is fixed to the body part 14. More precisely, the assembly part 10 is clipped onto the dashboard 12 by the male part 16 and the assembly formed by the assembly part 10 and the dashboard 12 is fixed to the body part 14 by the female part 15. The body part 14 can be the body itself or an attached part fixed to the body, for example welded or clipped onto the body.
[0021] Dans la suite de la description, le repère illustré sur les figures 1-3 représente la direction verticale Z, la direction longitudinale X et la direction transversale Y. Les éléments ci-après sont décrits en référence à ces directions X, Y et Z, lorsque la planche de bord 12 est assemblée à la partie de caisse 14 par l’intermédiaire de la pièce d’assemblage 10, c’est-à-dire en condition normale d’utilisation du véhicule 50 équipé de la planche de bord 12. In the remainder of the description, the mark illustrated in Figures 1-3 represents the vertical direction Z, the longitudinal direction X and the transverse direction Y. The following elements are described with reference to these directions X, Y and Z, when the dashboard 12 is assembled to the body part 14 by means of the assembly part 10, that is to say in normal condition of use of the vehicle 50 equipped with the edge 12.
[0022] La planche de bord 12 comprend une surface externe 11, accessible à un utilisateur en condition normale. Les éléments sous la surface externe 11 ne sont en pratique pas accessible à un utilisateur du véhicule 50 en condition normale. Sous la surface externe 11, la planche de bord 12 comprend notamment une partie verticale 12C et deux parties latérales 12D. La partie verticale 12C est rectangulaire et s’étend principalement selon la direction transversale Y. La partie verticale 12C comprend une première ouverture 12A. La première ouverture 12A s’étend principalement selon la direction transversale Y. En outre, la première ouverture 12A est rectangulaire. La première ouverture 12A est délimitée verticalement, en hauteur par un bord supérieur 45 et un bord inférieur 44. La distance entre le bord supérieur 45 et le bord inférieur 44 définit une hauteur 43. En outre, comme ceci est illustré sur la figure 2, la planche de bord 12 peut comprendre, de part et d’autre de la partie verticale 12C, une partie latérale 12D. La planche de bord 12 comprend ainsi deux parties latérales 12D, qui s’étendent principalement selon la direction longitudinale X, c’est-à-dire perpendiculairement à la partie verticale 12C. Les parties latérales 12C sont sensiblement rectangulaires. L’ensemble formé par la partie verticale 12C et les parties latérales 12C forment un « U ». The dashboard 12 comprises an outer surface 11, accessible to a user in normal condition. The elements under the outer surface 11 are in practice not accessible to a user of the vehicle 50 in normal condition. Under the outer surface 11, the dashboard 12 comprises in particular a vertical part 12C and two side parts 12D. The vertical part 12C is rectangular and extends mainly in the transverse direction Y. The vertical part 12C comprises a first opening 12A. The first opening 12A extends mainly in the transverse direction Y. Furthermore, the first opening 12A is rectangular. The first opening 12A is delimited vertically, in height by an upper edge 45 and a lower edge 44. The distance between the upper edge 45 and the lower edge 44 defines a height 43. Further, as illustrated in FIG. 2, the dashboard 12 may comprise, on either side of the vertical part 12C, a side part 12D. The dashboard 12 thus comprises two side parts 12D, which extend mainly in the longitudinal direction X, that is to say perpendicular to the vertical part 12C. The side parts 12C are substantially rectangular. The assembly formed by the vertical part 12C and the side parts 12C form a “U”.
[0023] En outre, la planche de bord 12 comprend une deuxième ouverture 12B. La deuxième ouverture 12B est accessible depuis l’habitacle du véhicule 50 lorsque la planche de bord 12 est fixée sur la caisse pour une utilisation normale du véhicule 50. Par exemple, la deuxième ouverture 12B correspond à un trou d’une grille de désembuage. In addition, the dashboard 12 includes a second opening 12B. The second opening 12B is accessible from the passenger compartment of the vehicle 50 when the dashboard 12 is attached to the body for normal use of the vehicle 50. For example, the second opening 12B corresponds to a hole in a demisting grille.
[0024] La partie femelle 15 se présente sous la forme d’un « U », et comprend une base 15A et deux branches 15B perpendiculaires à la base 15A. La base 15A s’étend principalement selon la direction transversale Y tandis que les branches 15B s’étendent principalement selon la direction longitudinale X. Selon la direction transversale Y, une des branches 15B est situé au dessus de l’autre branche 15B. On peut donc qualifier les branches 15B de « branche supérieure » et « branche inférieure ». Les branches 15B et la base 15A délimitent un espace 30 recevant la partie de caisse 14. Plus précisément, les branches 15B comprennent une surface interne 31 du côté de l’espace 30, c’est-à-dire en regard de l’espace 30. La surface interne 31 comprend une zone de fixation 32 pour venir en prise avec la partie de caisse 14. Alternativement, chacune des deux ou uniquement une des deux surfaces interne 31 comprend une zone de fixation 32. Par exemple, comme ceci est illustré sur la figure 1 , la zone de fixation 32 se situe sur la surface interne de la branche 15B inférieure, La zone de fixation 32, peut par exemple constituer une zone dentée 32, qui comprend par exemple des dents de scie 36, et accroche la partie de caisse 14. Dans l’exemple illustré à la figure 3, la zone dentée 32 est agencée dans l’espace 30. La partie de caisse 14 peut comprendre une forme, avec des dents de scie 35, complémentaire à celle de la zone de fixation 32. La zone de fixation 32 permet de maintenir la planche de bord 12 sur la caisse 14, en bloquant les mouvements de translation selon l’axe X pouvant survenir entre la planche de bord 12 et la caisse 14. Comme visible en détail sur la figure 1 , chaque dent de scie 36 de la zone de fixation 32 se compose d’une partie oblique 33 et d’une partie droite 34. La partie oblique 33 est croissante selon la direction longitudinale X. La partie droite 34 s’étend parallèlement selon la direction verticale Z. La forme complémentaire en dents de scie 35 de la partie de caisse 14 comprend des dents dont les parties obliques 37 et les parties droites 38 sont complémentaires à celles de la zone de fixation 32 de la partie femelle 15. En particulier, la partie oblique 37 des dents de scie 35 de la partie de caisse 14 est croissante selon la direction longitudinale X. La partie droite 38 des dents de scie 35 de la partie de caisse 14 s’étend parallèlement selon la direction verticale Z. La forme des dents de scie de la zone de fixation 32 et de la partie de caisse 14 permet de bloquer le mouvement dans le sens positif selon la direction longitudinale X. En revanche, le mouvement dans le sens négatif selon la direction longitudinale X reste autorisé, ceci permettant notamment de glisser la pièce d’assemblage 10 (le sens négatif selon la direction longitudinale X) sur la partie de caisse 14 lors de l’assemblage de la planche de bord 12 avec la caisse de véhicule. La forme en dents de scie présentée ici est particulièrement avantageuse car elle permet d’ajuster au mieux la distance entre le crochet 16B de la partie mâle 16, détaillé ci-après, et de limiter les jeux d’assemblage entre la pièce d’assemblage 10 et la partie de caisse 14. Une fois la partie de caisse 14 et la planche de bord 12 assemblées via la pièce d’assemblage 10, le désassemblage (c’est-à-dire le mouvement de la pièce d’assemblage 10 dans le sens positif selon la direction longitudinale X) n’est pas possible sauf à l’aide d’un outil de désassemblage qui est décrit ci-après. The female part 15 is in the form of a "U", and comprises a base 15A and two branches 15B perpendicular to the base 15A. The base 15A extends mainly in the transverse direction Y while the branches 15B extend mainly in the longitudinal direction X. In the transverse direction Y, one of the branches 15B is located above the other branch 15B. The branches 15B can therefore be qualified as “upper branch” and “lower branch”. The branches 15B and the base 15A delimit a space 30 receiving the body part 14. More precisely, the branches 15B comprise an internal surface 31 on the side of the space 30, that is to say facing the space. 30. The internal surface 31 comprises an attachment zone 32 for engaging with the body part 14. Alternatively, each of the two or only one of the two internal surfaces 31 comprises an attachment zone 32. For example, as illustrated. in Figure 1, the fastening zone 32 is located on the internal surface of the lower branch 15B, The fastening zone 32, can for example constitute a toothed zone 32, which comprises for example saw teeth 36, and hooks the body part 14. In the example illustrated in FIG. 3, the toothed zone 32 is arranged in the space 30. The body part 14 may comprise a shape, with saw teeth 35, complementary to that of the zone. fixing 32. The fixing zone 32 makes it possible to maintain the panel 12 on the body 14, by blocking the translational movements along the X axis that may occur between the dashboard 12 and the body 14. As visible in detail in Figure 1, each sawtooth 36 of the area fixing 32 consists of an oblique part 33 and a straight part 34. The oblique part 33 increases in the direction longitudinal X. The straight part 34 extends parallel in the vertical direction Z. The complementary sawtooth shape 35 of the body part 14 comprises teeth of which the oblique parts 37 and the straight parts 38 are complementary to those of the body part 14. fixing zone 32 of the female part 15. In particular, the oblique part 37 of the saw teeth 35 of the body part 14 increases in the longitudinal direction X. The straight part 38 of the saw teeth 35 of the body part 14 extends parallel in the vertical direction Z. The shape of the saw teeth of the fixing zone 32 and of the body part 14 makes it possible to block the movement in the positive direction in the longitudinal direction X. On the other hand, the movement in the negative direction in the longitudinal direction X remains authorized, this allowing in particular to slide the assembly part 10 (the negative direction in the longitudinal direction X) on the body part 14 during assembly ge of the dashboard 12 with the vehicle body. The sawtooth shape presented here is particularly advantageous because it makes it possible to best adjust the distance between the hook 16B of the male part 16, detailed below, and to limit the assembly clearances between the assembly part. 10 and the body part 14. Once the body part 14 and the dashboard 12 assembled via the assembly part 10, the disassembly (that is to say the movement of the assembly part 10 in the positive direction in the longitudinal direction X) is not possible except using a disassembly tool which is described below.
[0025] Alternativement, tel qu’illustré sur la figure 1, la branche 15B comprend une partie d’appui 15C. Cette partie d’appui 15C est prévue pour être en appui sur la partie de caisse 14. La partie d’appui 15C se situe entre l’extrémité libre de la branche supérieure 15B et la base 15A, par exemple vers le milieu de la branche 15B selon la direction longitudinale X. La partie d’appui 15C assure l’appui permanent de la partie femelle 15 sur la partie de caisse 14, ceci afin d’éviter que les dents de la partie femelle 15 et de la partie de caisse 14 se détachent et affaiblissent la connexion entre ces deux parties 14, 15. Par ailleurs, la partie d’appui 15C entraîne une réduction en hauteur selon la direction verticale Y de l’espace 30. En d’autres termes, l’espace 30 de la partie femelle 15 est plus grand à son ouverture formée par son extrémité libre afin de faciliter l’introduction de la partie de caisse 14 dans la partie femelle 15 puis se rétrécit dans la zone de la partie d’appui 15C. Alternatively, as illustrated in Figure 1, the branch 15B comprises a support part 15C. This support part 15C is designed to rest on the body part 14. The support part 15C is located between the free end of the upper branch 15B and the base 15A, for example towards the middle of the branch. 15B in the longitudinal direction X. The bearing part 15C ensures the permanent support of the female part 15 on the body part 14, in order to prevent the teeth of the female part 15 and of the body part 14 become detached and weaken the connection between these two parts 14, 15. Furthermore, the bearing part 15C causes a reduction in height in the vertical direction Y of the space 30. In other words, the space 30 of the female part 15 is larger at its opening formed by its free end in order to facilitate the introduction of the body part 14 in the female part 15 then narrows in the area of the bearing part 15C.
[0026] La partie mâle 16 est sensiblement plate. La partie mâle 16 s’étend selon la direction longitudinale X. En particulier, la partie mâle 16 s’étend depuis une première extrémité 16A jusqu’à une deuxième extrémité 16B. La première extrémité 16A est en contact avec la partie femelle 15. Plus précisément, la première extrémité 16A est en contact avec la base 15A de la partie femelle 15. En outre, la première extrémité 16A s’étend selon la même direction transversale Y que la base 15A. La deuxième extrémité 16B est libre. En outre, la deuxième extrémité 16B se présente sous la forme d’un crochet. The male part 16 is substantially flat. The male part 16 extends in the longitudinal direction X. In particular, the male part 16 extends from a first end 16A to a second end 16B. The first end 16A is in contact with the female part 15. More precisely, the first end 16A is in contact with the base 15A of the female part 15. In addition, the first end 16A extends in the same transverse direction Y as the base 15A. The second end 16B is free. In addition, the second end 16B is in the form of a hook.
[0027] On définit par ailleurs un plan moyen P16, visible à la figure 3. Ce plan moyen P16 est le plan qui s’étend entre la première extrémité 16A et la deuxième extrémité 16B de la partie mâle 16, selon les directions longitudinale X et transversale Y. En outre, le plan moyen P16 divise la partie mâle 16 en deux parties sensiblement égale dans la direction verticale Z. Le plan moyen P16 peut ainsi être qualifié de plan médian. Le plan moyen P16 correspond en outre à un plan défini lorsque la partie mâle 16 est immobile. En d’autres termes, si la partie mâle 16 est mobile par rapport aux éléments constitutifs de la pièce d’assemblage 10, le plan moyen P16 reste fixe par rapport au mouvement de la partie mâle 16. We also define a mean plane P16, visible in Figure 3. This mean plane P16 is the plane which extends between the first end 16A and the second end 16B of the male part 16, in the longitudinal directions X and transverse Y. In addition, the mean plane P16 divides the male part 16 into two parts substantially equal in the vertical direction Z. The mean plane P16 can thus be qualified as a midplane. The mean plane P16 also corresponds to a plane defined when the male part 16 is stationary. In other words, if the male part 16 is movable relative to the constituent elements of the assembly part 10, the mean plane P16 remains fixed relative to the movement of the male part 16.
[0028] Avantageusement, la partie mâle 16 est élastiquement déformable. Par « élastiquement déformable », on comprend que la parte mâle 16 est suffisamment rigide pour conserver sa forme propre sans le concours d’un quelconque support, et suffisamment souple pour plier sous l’action d’une force appliquée par exemple sur la deuxième extrémité 16B. Advantageously, the male part 16 is elastically deformable. By “elastically deformable”, it is understood that the male part 16 is sufficiently rigid to retain its own shape without the aid of any support, and sufficiently flexible to bend under the action of a force applied for example on the second end. 16B.
[0029] Lorsque la planche de bord 12 est assemblée à la partie de caisse 14, la deuxième extrémité 16B est logée dans la première ouverture 12A de la planche de bord 12. La deuxième extrémité 16B se présente sous la forme d’un crochet, qui autorise le mouvement de la deuxième extrémité 16B dans l’ouverture 12A dans le sens positif selon la direction longitudinale X mais qui bloque ce même mouvement dans le sens négatif selon la direction longitudinale X. Plus précisément, comme illustré sur la figure 3, la deuxième extrémité 16B comprend une surface verticale 40 et une surface inclinée 42. La surface verticale 40 s’étend parallèlement à la direction verticale Z et se situe en regard de la base 15A de la partie femelle 15. La surface inclinée 42 est décroissante selon la direction longitudinale X, depuis la surface verticale 40. La deuxième extrémité 16B a une hauteur 41 mesurée selon la direction verticale Z légèrement inférieure à la hauteur 43 de l’ouverture 12A, mesurée également selon la direction verticale Z. En particulier, lorsque la planche de bord 12 est assemblée à la partie de caisse 14, la deuxième extrémité 16B repose sur le bord supérieur 45 de la première ouverture 12A, et la surface verticale 40 de la deuxième extrémité 16B constitue une surface de butée 24 contre laquelle bute la planche de bord 12, ce qui bloque le mouvement de la deuxième extrémité 16B dans la première ouverture 12A dans le sens négatif selon la direction longitudinale X. When the dashboard 12 is assembled to the body part 14, the second end 16B is housed in the first opening 12A of the dashboard 12. The second end 16B is in the form of a hook, which allows the movement of the second end 16B in the opening 12A in the positive direction in the longitudinal direction X but which blocks this same movement in the negative direction in the longitudinal direction X. More precisely, as illustrated in FIG. 3, the second end 16B comprises a vertical surface 40 and an inclined surface 42. The vertical surface 40 extends parallel to the vertical direction Z and is located opposite the base 15A of the female part 15. The inclined surface 42 decreases in the longitudinal direction X, from the vertical surface 40. The second end 16B has a height 41 measured according to the vertical direction Z slightly less than the height 43 of the opening 12A, also measured in the vertical direction Z. In particular, when the dashboard 12 is assembled to the body part 14, the second end 16B rests on the upper edge 45 of the first opening 12A, and the vertical surface 40 of the second end 16B constitutes an abutment surface 24 against which the dashboard 12 abuts, which blocks the movement of the second end 16B in the first opening 12A in the direction negative in the longitudinal direction X.
[0030] Afin de détacher la planche de bord 12 de la caisse (et de la pièce d’assemblage 10 fixée sur la partie de caisse 14), il est possible de passer un outil fin et long, tel que par exemple un tournevis, à travers la deuxième ouverture 12B pour venir appuyer sur la deuxième extrémité 16B. La partie mâle 16 étant élastiquement déformable, la force exercée sur la deuxième extrémité 16B par l’outil entraine l’inclinaison de la partie mâle 16 vers le bas selon la direction verticale Z. La hauteur 41 de la deuxième pièce 16 étant inférieure à la hauteur 43 de la première ouverture 12A, la deuxième extrémité 16B peut traverser la première ouverture 12A (c’est-à-dire se déplacer dans le sens négatif selon la direction longitudinale X), ce qui déverrouille la pièce d’assemblage 10 de la planche de bord 12. In order to detach the dashboard 12 from the body (and from the assembly part 10 fixed to the body part 14), it is possible to use a thin and long tool, such as for example a screwdriver, through the second opening 12B to press on the second end 16B. The male part 16 being elastically deformable, the force exerted on the second end 16B by the tool causes the inclination of the male part 16 downwards in the vertical direction Z. The height 41 of the second part 16 being less than the height. height 43 of the first opening 12A, the second end 16B can pass through the first opening 12A (that is to say move in the negative direction in the longitudinal direction X), which unlocks the assembly part 10 of the dashboard 12.
[0031] Alternativement, la pièce d’assemblage comprend deux parois latérales 20, illustrées par exemple sur les figures 1 à 3. Les parois latérales 20 sont agencées de part et d’autre de la partie mâle 16. Plus précisément, les parois latérales 20 sont disposées selon un plan perpendiculaire P20 à la partie mâle 16 et s’étendent chacune depuis la partie femelle 15 jusqu’à une extrémité libre de paroi latérale 22. Chaque paroi latérale 20 comprend un passage 21. Le passage 21 est apte à recevoir une protubérance 18 de la partie mâle 16. Les parois latérales 20 empêchent des mouvements de translation entre la pièce d’assemblage 10 et la planche de bord 12 et empêchent donc indirectement des mouvements de translation entre la planche de bord 12 et la partie de caisse 14. En particulier, les parois latérales 20 bloquent le mouvement de translation selon la direction transversale Y et le mouvement de translation dans le sens positif selon la direction longitudinale X. Plus précisément, les parois latérales 20 s’étendent perpendiculairement à la partie mâle 16, depuis la base 15A de la partie femelle 15 vers la deuxième extrémité 16B de la partie mâle 16. Les parois latérales 20 sont fixées à la partie femelle 15, en revanche, elles ne sont pas fixées à la partie mâle 16, ce qui permet à la partie mâle 16 d’être mobile par rapport aux parois latérales 20. Plus précisément, la deuxième extrémité 16B de la partie mâle 16 est mobile perpendiculairement à un plan moyen P16 de ladite partie mâle 16 par rapport aux parois latérales 20 et à la partie femelle 15. Toutefois, le mouvement de la partie mâle 16 par rapport aux parois latérales 20 est limité par la protubérance 18 qui est engagée dans le passage 21. Les parois latérales 20 sont moins longues que la partie mâle 16. Cette différence de longueur délimite un espace 25 apte à recevoir une partie de la planche de bord 12, et en particulier la partie verticale 12C de la planche de bord 12. Alternatively, the assembly part comprises two side walls 20, illustrated for example in Figures 1 to 3. The side walls 20 are arranged on either side of the male part 16. More precisely, the side walls 20 are arranged in a plane P20 perpendicular to the male part 16 and each extend from the female part 15 to a free end of the side wall 22. Each side wall 20 comprises a passage 21. The passage 21 is suitable for receiving a protuberance 18 of the male part 16. The side walls 20 prevent translational movements between the assembly part 10 and the dashboard 12 and therefore indirectly prevent translational movements between the dashboard 12 and the body part 14. In particular, side walls 20 block the translational movement in the transverse direction Y and the translational movement in the positive direction along the longitudinal direction X. More precisely, the side walls 20 extend perpendicularly to the male part 16, from the base 15A of the female part 15 towards the second end 16B of the male part 16. The side walls 20 are fixed to the female part 15, on the other hand, they are not fixed to the male part 16, which allows the male part 16 to 'be movable relative to the side walls 20. More precisely, the second end 16B of the male part 16 is movable perpendicularly to a mean plane P16 of said male part 16 relative to the side walls 20 and to the female part 15. However, the movement of the male part 16 relative to the side walls 20 is limited by the protuberance 18 which is engaged in the passage 21. The side walls 20 are shorter than the male part 16. This difference in length delimits a space 25 capable of receiving a part of the dashboard 12, and in particular the vertical part 12C of the dashboard 12.
[0032] La planche de bord 12 peut ainsi venir s’insérer verticalement entre les parois latérales 20 et la deuxième extrémité 16B de la partie mâle 16. Les extrémités des parois latérales 20, opposées aux extrémités en contact avec la partie femelle 15, forment les extrémités libres 22 de paroi latérale et forment des surfaces de butée 23 pour bloquer le mouvement de la planche de bord 12 dans le sens négatif selon la direction longitudinale X. Par conséquent, la surface de butée 24 de la partie mâle 16 et les surfaces de butée 23 des parois latérales 20 sont disposées en regard et délimitent l’espace 25 apte à recevoir une partie de la planche de bord 12 pour bloquer la planche de bord 12 en translation selon la direction longitudinale X par rapport à la pièce d’assemblage 10. The dashboard 12 can thus be inserted vertically between the side walls 20 and the second end 16B of the male part 16. The ends of the side walls 20, opposite the ends in contact with the female part 15, form the free ends 22 of the side wall and form stop surfaces 23 for blocking the movement of the dashboard 12 in the negative direction in the longitudinal direction X. Therefore, the stop surface 24 of the male part 16 and the surfaces stop 23 of the side walls 20 are arranged opposite and delimit the space 25 adapted to receive a part of the dashboard 12 to block the dashboard 12 in translation in the longitudinal direction X relative to the assembly part 10.
[0033] En outre, les parties latérales 12D de la planche de bord 12 enserrent la pièce d’assemblage 10. Plus précisément, les parties latérales 12D encadrent les parois latérales 20 et la partie mâle 16 de la pièce d’assemblage 10. Le mouvement en translation selon la direction Y de la pièce d’assemblage 10 est ainsi limité par les parties latérales 12D de la planche de bord 12. Par ailleurs, comme ceci peut se comprendre de la figure 2, les parois latérales 20 servent également de guide à la bonne introduction de la partie mâle 16 dans la première ouverture 12A, en étant bloquées de part et d’autre par les parties latérales 12D. In addition, the side parts 12D of the dashboard 12 enclose the assembly part 10. More precisely, the side parts 12D surround the side walls 20 and the male part 16 of the assembly part 10. The translational movement in the Y direction of the assembly part 10 is thus limited by the side parts 12D of the dashboard 12. Moreover, as can be understood from Figure 2, the side walls 20 serve also as a guide to the correct introduction of the male part 16 into the first opening 12A, being blocked on either side by the side parts 12D.
[0034] Par ailleurs, la partie mâle 16 comprend deux bords latéraux 17 disposés latéralement de part et d’autre. Chacun des deux bords latéraux 17 s’étend entre la première extrémité 16A et la deuxième extrémité 16B. Chaque bord latéral 17 fait face à une des deux parties latérales 20. En outre, chaque bord latéral 17 comprend une protubérance 18. Chaque protubérance 18 coopère avec le passage 21 de la partie latérale 20 faisant face au bord latéral 17 correspondant. La protubérance 18, en étant logée dans le passage 21, limite le mouvement vertical selon la direction Z de la partie mâle 16 par rapport à la partie femelle 15 lorsqu’une force est appliquée sur la deuxième extrémité 16B de la partie mâle. Ceci évite notamment la rupture de la partie mâle 16 du reste de la pièce d’assemblage 10, c’est-à-dire à la pièce mâle 16 de se désolidariser de la partie femelle 15. [0034] Furthermore, the male part 16 comprises two side edges 17 arranged laterally on either side. Each of the two side edges 17 extends between the first end 16A and the second end 16B. Each side edge 17 faces one of the two side parts 20. In addition, each side edge 17 comprises a protuberance 18. Each protuberance 18 cooperates with the passage 21 of the side part 20 facing the corresponding side edge 17. The protuberance 18, by being housed in the passage 21, limits the vertical movement in the Z direction of the male part 16 relative to the female part 15 when a force is applied to the second end 16B of the male part. This prevents in particular the breaking of the male part 16 from the rest of the assembly part 10, that is to say the male part 16 from becoming detached from the female part 15.
[0035] Selon un autre exemple de réalisation, la pièce d’assemblage comprend en outre une butée élastique 26, illustrée aux figures 4 et 5. Cette butée élastique 26 peut être intégrée à la partie mâle (figure 4) ou à la planche de bord 12 (figure 5). La butée élastique 26 participe au maintien vers le haut (selon la direction verticale Y) de la partie mâle 16 afin que celle-ci reste en appui sur le bord supérieur 45 de la première ouverture 12A de la planche de bord. En particulier, la butée élastique 26 met en contact la partie mâle 16 avec la planche de bord 12. According to another exemplary embodiment, the assembly part further comprises an elastic stop 26, illustrated in Figures 4 and 5. This elastic stop 26 can be integrated into the male part (Figure 4) or the board. edge 12 (figure 5). The resilient stop 26 participates in maintaining upward (in the vertical direction Y) of the male part 16 so that the latter rests on the upper edge 45 of the first opening 12A of the dashboard. In particular, the elastic stop 26 brings the male part 16 into contact with the dashboard 12.
[0036] La butée élastique 26 se présente par exemple sous la forme d’un pion creux, suffisamment déformable pour pouvoir libérer le crochet 16B de la première ouverture 12A et ainsi détacher la planche de bord 12 de la caisse. The elastic stop 26 is for example in the form of a hollow pin, sufficiently deformable to be able to release the hook 16B from the first opening 12A and thus detach the dashboard 12 from the body.
[0037] Comme illustré sur la figure 4, la butée élastique est agencée sur la face inférieure de la partie mâle 16, en regard d’une partie de la planche de bord 12 agencée selon la direction longitudinale. Sur la figure 5, la butée élastique est inversement agencée sur la partie de la planche de bord 12 agencée selon la direction longitudinale, en regard de la face inférieure de la partie mâle 16. As illustrated in Figure 4, the elastic stopper is arranged on the underside of the male part 16, facing a part of the dashboard 12 arranged in the longitudinal direction. In FIG. 5, the elastic stopper is inversely arranged on the part of the dashboard 12 arranged in the longitudinal direction, facing the underside of the male part 16.
