Description
ENSEMBLE D’UN CAISSON DE BASSE ET D’UNE ROUE DE SECOURS POUR ASSEMBLY OF A BASS CASE AND A RESCUE WHEEL FOR
VEHICULE VEHICLE
[001] L'invention concerne, de façon générale, le domaine de l’intégration d’un caisson de basse dans une cuvette de roue de secours de véhicule, et vise plus précisément un moyen de fixation destiné à un ensemble d’une roue de secours et d’un caisson de basse, dans un coffre de véhicule, notamment un coffre arrière. [001] The invention relates generally to the field of integration of a subwoofer in a vehicle spare tire bowl, and more specifically to a fastening means for a wheel assembly. emergency and a subwoofer, in a vehicle trunk, including a trunk.
[002] Da manière connue, un véhicule comprend une roue de secours. Cette roue de secours est utile en cas de crevaison d’un pneumatique et permet de remplacer provisoirement la roue ayant subi ladite crevaison. [002] In known manner, a vehicle comprises a spare wheel. This spare wheel is useful in case of puncture of a tire and can temporarily replace the wheel having suffered the puncture.
[003] Il est connu de stocker une roue de secours, par exemple une roue galette, dans une cuvette, autrement dit une cavité, réservée dans la coffre arrière du véhicule. Afin que la roue de secours ne puisse pas se déplacer lorsque le véhicule est en mouvement, un moyen de fixation est utilisé pour solidariser la roue de secours à la cuvette de roue de secours, également désignée cuvette de plancher du véhicule, la cuvette de plancher du véhicule correspondant à l’espace dédié au stockage de la roue de secours. [003] It is known to store a spare wheel, for example a pancake wheel, in a bowl, in other words a cavity, reserved in the trunk of the vehicle. In order that the spare wheel can not move when the vehicle is moving, a fastening means is used to secure the spare wheel to the spare tire bowl, also referred to as the vehicle floor pan, the floor bowl. the vehicle corresponding to the space dedicated to storing the spare wheel.
[004] Toutefois, un inconvénient inhérent à la présence d’une roue de secours dans la cuvette de plancher du véhicule, que ce soit dans le coffre ou sous les sièges, réside dans la perte de volume engendrée. Notamment pour valoriser l’espace perdu occupé par la roue de secours, il est connu d’installer un caisson de basse dans le volume intérieur laissé libre par la roue de secours. [004] However, a disadvantage inherent in the presence of a spare wheel in the vehicle floor bowl, whether in the trunk or under the seats, lies in the loss of volume generated. In particular to enhance the lost space occupied by the spare wheel, it is known to install a subwoofer in the interior volume left free by the spare wheel.
[005] En effet, il est fréquent qu’un véhicule dispose d’une option Hi-Fi permettant de transmettre, reproduire et diffuser un signal sonore, par exemple la musique ou bien la radio, dans l’habitacle de la voiture. Afin de reproduire et diffuser correctement et fidèlement un signal sonore, des haut-parleurs sont installés dans l’habitacle de la voiture. Un haut-parleur classique n’est cependant pas adapté pour diffuser les fréquences les plus basses avec une bonne qualité de restitution. Il est par conséquent également connu d’utiliser un caisson de basse, spécialisé dans la diffusion de signaux à basse fréquence. [005] Indeed, it is common that a vehicle has a Hi-Fi option to transmit, reproduce and broadcast a sound signal, for example music or radio, in the passenger compartment of the car. In order to reproduce and correctly broadcast a sound signal, speakers are installed in the passenger compartment of the car. A conventional speaker is however not suitable for broadcasting the lowest frequencies with a good playback quality. It is therefore also known to use a subwoofer, specialized in the broadcasting of low frequency signals.
[006] En référence à la figure 1 , représentative de l’état de l’art, on désignera l’axe X comme celui étant parallèle à l’axe longitudinal du véhicule et l’axe Z comme étant l’axe parallèle à la verticale terrestre. Une vis traversante 101 filetée est fixée verticalement, c’est- à-dire selon l’axe Y, au centre de la cuvette de plancher de véhicule.
[007] Selon l’état de la technique, la roue de secours 3 est ainsi placée en position couchée, autrement dit selon l’axe X, dans la cuvette de plancher du véhicule, et l’ouverture centrale de la roue de secours 3 se visse sur la vis traversante 101. En effet, la forme du caisson de basse 200 est adaptée à la surface interne SI du volume intérieur libre de la roue de secours 3 et le caisson de basse 200 comprend une ouverture circulaire centrale, dont le diamètre est supérieur au diamètre de la vis traversante 101. Par ailleurs, le caisson de basse 200 comprend un pas de vis interne 202 à son ouverture centrale et ce pas de vis interne 202 est adapté pour permettre le vissage du caisson de basse 200 sur le pas de vis externe 103 de la vis traversante 101. Le caisson de basse 200 est par conséquent placé dans le volume intérieur libre de la roue de secours 3 et autour de la vis traversante 101. La zone ZL01 correspond au volume intérieur libre de la roue de secours 3 où est positionné le haut-parleur 201 du caisson de basse 200. [006] Referring to Figure 1, representative of the state of the art, the X axis will be designated as being parallel to the longitudinal axis of the vehicle and the Z axis as the axis parallel to the terrestrial vertical. A threaded through screw 101 is fixed vertically, that is, along the Y axis, in the center of the vehicle floor pan. [007] According to the state of the art, the spare wheel 3 is thus placed in a supine position, in other words along the X axis, in the vehicle floor bowl, and the central opening of the spare wheel 3. is screwed on the through screw 101. Indeed, the shape of the subwoofer 200 is adapted to the inner surface SI of the free inner volume of the spare wheel 3 and the subwoofer 200 comprises a central circular opening, the diameter of which is greater than the diameter of the through screw 101. Furthermore, the subwoofer 200 comprises an internal thread 202 at its central opening and this internal thread 202 is adapted to allow the screwing of the subwoofer 200 on the not external screw 103 of the through screw 101. The subwoofer 200 is therefore placed in the free inner volume of the spare wheel 3 and around the through screw 101. The zone ZL01 corresponds to the free internal volume of the wheel of relief 3 where is positioned the speaker 201 of the subwoofer 200.
[008] Toujours en référence à la figure 1 , afin de fixer l’ensemble caisson de basse 200 et roue de secours 3 à la carrosserie, on utilise un moyen de fixation adapté pour se visser sur la partie supérieure de la vis traversante 101. [008] Still with reference to Figure 1, in order to fix the subwoofer assembly 200 and spare wheel 3 to the body, is used a fastening means adapted to be screwed on the upper part of the through screw 101.
[009] Cependant, la taille et la position de ladite vis traversante 101 limitent grandement le volume de la zone ZL01 , volume intérieur libre de la roue de secours 3, où est positionné le haut-parleur 201 du caisson de basse 200. Par conséquent, la taille du haut-parleur 201 de caisson de basse 200 est elle-aussi limitée. En pratique, la surface maximale de la membrane de haut-parleur 201 est typiquement de l’ordre de 133 cm2. [009] However, the size and the position of said through screw 101 greatly limit the volume of the zone ZL01, the free internal volume of the spare wheel 3, where the speaker 201 of the subwoofer 200 is positioned. , the size of the subwoofer speaker 200 is also limited. In practice, the maximum surface area of the speaker membrane 201 is typically of the order of 133 cm 2 .
[0010] Comme dit précédemment, pour diffuser correctement un signal à basse fréquence, il faut déplacer un volume d’air important, et donc, augmenter au maximum le diamètre de la membrane du haut-parleur 201 ce qui n’est pas le cas ici. On constate pourtant, sur la figure 1 , qu’une zone inutilisée ZI n’est pas valorisée. La qualité du son diffusé, en particulier des basses, dans ces systèmes connus, est donc médiocre puisque les solutions permettant d’augmenter le diamètre de la membrane du haut-parleur 201 sont trop coûteuses ou impossibles à mettre en œuvre. As said before, to properly broadcast a low frequency signal, it is necessary to move a large volume of air, and therefore, increase the maximum diameter of the speaker membrane 201 which is not the case. right here. However, we see in Figure 1, an unused area ZI is not valued. The quality of the sound diffused, in particular bass, in these known systems, is therefore mediocre since the solutions making it possible to increase the diameter of the membrane of the loudspeaker 201 are too expensive or impossible to implement.
[0011] L’invention vise à résoudre au moins en partie ces inconvénients en proposant un moyen de fixation permettant de préserver un volume important, à l’intérieur du volume de la cuvette laissé libre par la roue de secours, pour y loger un caisson de basse. The invention aims to solve at least in part these disadvantages by providing a fastening means for preserving a large volume, inside the volume of the bowl left free by the spare wheel, to accommodate a box bass.
[0012] A cette fin, la présente invention comprend un moyen de fixation ne traversant pas le caisson de basse 200 de part en part, permettant ainsi d’augmenter le volume de la zone
ZL01 et d’augmenter les dimensions de la membrane du haut-parleur 201 et ainsi la qualité du son. For this purpose, the present invention comprises a fastening means not passing through the subwoofer 200 from one side to the other, thus making it possible to increase the volume of the zone. ZL01 and increase the dimensions of the speaker diaphragm 201 and so the sound quality.

According to this embodiment, the second portion comprises a thread 12AF made on the vertical flange located on the ends of the flat head 12A of the fastening nut 12.
[0036] S’agissant de la première partie, le moyen de fixation et la cuvette de plancher de véhicule coopèrent afin de fixer la roue de secours 3. En effet, le goujon de fixation 11 est
solidarisé à la cuvette de plancher du véhicule. Par ailleurs, le taraudage 12BT de la partie interne de la partie basse 12B de l’écrou de fixation 12 est adapté pour coopérer avec le filetage latéral 1 1 F du goujon de fixation 1 1. Autrement dit, le taraudage 12BT de la partie interne de la partie basse 12B de l’écrou de fixation 12 est adapté pour se visser sur le filetage latéral 1 1 F du goujon de fixation 1 1. Regarding the first part, the fastening means and the vehicle floor pan cooperate to fix the spare wheel 3. In fact, the fixing stud 11 is secured to the floor pan of the vehicle. Furthermore, the tapping 12BT of the inner part of the lower part 12B of the fastening nut 12 is adapted to cooperate with the lateral thread 1 1 F of the fastening pin 1 1. In other words, the tapping 12BT of the inner part the lower part 12B of the fastening nut 12 is adapted to be screwed onto the lateral thread 1 1 F of the fixing stud 1 1.
[0037] S’agissant de la deuxième partie, l’embase 22 du caisson de basse 20 et le moyen de fixation coopèrent pour assurer la solidarisation du caisson de basse 20 audit moyen de fixation. La gorge filetée 20F du caisson de basse 20 est adaptée pour coopérer avec le filetage 12AF de la tête plate 12A de l’écrou de fixation 12.

[0040] Pour assurer la permanence du serrage entre le caisson de basse 20 et la tête plate 12A de l’écrou de fixation 12 un cliquet peut en outre être ajouté. To ensure the permanence of the clamping between the subwoofer 20 and the flat head 12A of the fastening nut 12 a pawl can further be added.
[0041] L’invention a aussi pour objet un procédé de montage d’un ensemble d’une roue de secours 3 et d’un caisson de basse 20 comprenant un moyen de fixation. Selon ce procédé, la roue de secours 3 est d’abord disposée horizontalement dans la cuvette de plancher de véhicule sur un goujon vertical 11 soudé au fond de ladite cuvette. The invention also relates to a method of mounting an assembly of a spare wheel 3 and a subwoofer 20 comprising a fixing means. According to this method, the spare wheel 3 is first disposed horizontally in the vehicle floor pan on a vertical stud 11 welded to the bottom of said bowl.
[0042] Ensuite, la roue de secours 3 est solidarisée à la cuvette de plancher de véhicule par vissage de l’écrou de fixation 12 sur le goujon de fixation 1 1 , grâce au taraudage 12BT de la portion inférieure 12B de l’écrou de fixation 12, adapté pour coopérer avec le filetage
latéral 1 1 F du goujon de fixation 1 1. Après cette étape, la roue de secours 3 se trouve immobile et bloquée entre la cuvette de plancher de véhicule et la tête plate 12A de l’écrou de fixation 12. Then, the spare wheel 3 is secured to the vehicle floor bowl by screwing the fastening nut 12 on the fastening pin 1 1, thanks to the tapping 12BT of the lower portion 12B of the nut of the vehicle. fastener 12, adapted to cooperate with the thread Lateral 1 1 F of the fixing bolt 1 1. After this step, the spare wheel 3 is stationary and locked between the vehicle floor pan and the flat head 12A of the fixing nut 12.
[0043] Optionnellement, dans le cas où la couche en matériau souple 40 est utilisée, ladite couche en matériau souple 40 est disposée sur la surface supérieure de la tête plate 12A de l’écrou de fixation 12. Optionally, in the case where the layer of flexible material 40 is used, said layer of flexible material 40 is disposed on the upper surface of the flat head 12A of the fastening nut 12.
[0044] Enfin, le caisson de basse 20, comprenant le haut-parleur 21 , est placé horizontalement dans le volume intérieur libre de la roue de secours 3, en positionnant la surface sur laquelle a été réalisée la rainure filetée 20F en vis-à-vis du goujon de fixation 1 1. Pour fixer le caisson de basse 20 sur l’écrou de fixation 12, ledit caisson de basse 20 est vissé sur l’écrou de fixation 12. En effet, comme cela a été expliqué précédemment, la rainure filetée 20F du caisson de basse 20 est adaptée pour coopérer avec le filetage 12AF de la tête plate 12A de l’écrou de fixation 12. Finally, the subwoofer 20, comprising the speaker 21, is placed horizontally in the free inner volume of the spare wheel 3, positioning the surface on which was made the threaded groove 20F vis-à-vis With the fastening bolt 1 1, to fasten the subwoofer 20 to the fastening nut 12, said subwoofer 20 is screwed onto the fastening nut 12. In fact, as explained above, the threaded groove 20F of the subwoofer 20 is adapted to cooperate with the thread 12AF of the flat head 12A of the fastening nut 12.
[0045] Ainsi, grâce au moyen de fixation, le volume intérieur du caisson de basse 3 permettant de loger un haut-parleur 21 est plus important que puisque les dimensions du caisson de basse ne sont pas contraintes par l’environnement dudit caisson de basse 3, en particulier par le moyen de fixation celui-ci, conformément à la présente invention, ne traversant pas le caisson de basse 20 de part en part. Autrement dit, dans le cas de l’invention, il n’y a pas de vis traversant ledit volume intérieur libre du caisson de basse 3 de part en part. Thus, thanks to the fixing means, the interior volume of the subwoofer 3 for housing a speaker 21 is larger than the dimensions of the subwoofer are not constrained by the environment of said subwoofer 3, in particular by the fixing means thereof, according to the present invention, not passing through the subwoofer 20 from one side to the other. In other words, in the case of the invention, there is no screw passing through said free internal volume of the subwoofer 3 from one side to the other.
[0046] Le volume du caisson de basse 20 est plus grand, il est possible de mettre en œuvre un haut-parleur 21 dont les dimensions sont supérieures à celles du haut-parleur 201 du caisson de basse 200 représenté à la figure 1 , représentatif de l’état de la technique. En pratique, dans le cas de l’invention, la surface de la membrane du haut-parleur 21 est typiquement de l’ordre de 213cm2. La qualité de son à basse fréquence étant proportionnelle à la taille de la membrane du haut-parleur 21 , on améliore ainsi significativement la qualité desdits sons à basse fréquence. The volume of the subwoofer 20 is larger, it is possible to implement a speaker 21 whose dimensions are greater than those of the speaker 201 of the subwoofer 200 shown in Figure 1, representative of the state of the art. In practice, in the case of the invention, the surface of the diaphragm of the loudspeaker 21 is typically of the order of 213 cm 2 . Since the low frequency sound quality is proportional to the size of the speaker diaphragm 21, the quality of said low frequency sounds is significantly improved.
[0047] Par ailleurs, dans le cas d’un véhicule ne disposant pas de caisson de basse 20, ledit moyen de fixation peut aussi être utilisé pour fixer la roue de secours 3 dans la cuvette de plancher de véhicule et fixer un équipement, muni d’une embase taraudée telle que l’embase 22 du caisson de basse 20, sur le filetage 12AF de la tête plate 12A de l’écrou de fixation 12.
[0048] En référence aux figures 6 et 7, selon un deuxième mode de réalisation possible, moyen de fixation permet d’immobiliser la roue de secours 3 et le caisson de basse 2-20 par rapport à la cuvette de plancher du véhicule sans l’utilisation d’un écrou de fixation séparé, comme dans le premier mode de réalisation, l’écrou étant intégré au caisson de basse 2-20. Furthermore, in the case of a vehicle that does not have a subwoofer 20, said attachment means can also be used to fix the spare wheel 3 in the vehicle floor pan and fix equipment, provided with a threaded base such as the base 22 of the subwoofer 20, on the thread 12AF of the flat head 12A of the fixing nut 12. Referring to Figures 6 and 7, according to a second possible embodiment, fastening means immobilizes the spare wheel 3 and the subwoofer 2-20 relative to the floor of the vehicle without the tank. use of a separate fixing nut, as in the first embodiment, the nut being integrated in the subwoofer 2-20.
[0049] Ainsi, selon ce deuxième mode de réalisation et en référence aux figures 6 et 7, le moyen de fixation comprend : Thus, according to this second embodiment and with reference to FIGS. 6 and 7, the fixing means comprises:
un goujon de fixation 2-1 1 cylindrique, disposé verticalement, possédant un filetage latéral 2-11 F. Ce goujon de fixation 2-11 est court et, en tout état de cause, il ne traverse pas la zone ZL1 , définie comme étant le volume interne libre du caisson de basse 2-20 où est placé le haut-parleur 2-21. La zone ZL1 présente un volume beaucoup plus important que dans l’état de l’art, puisque le goujon de fixation 2-11 n’occupe aucun volume dans la zone ZL1. a vertically disposed cylindrical fixing pin 2-1 1 having a lateral thread 2-11 F. This fastening stud 2-11 is short and, in any case, it does not cross the zone ZL1, defined as being the free internal volume of the subwoofer 2-20 where the loudspeaker 2-21 is placed. The ZL1 zone has a much larger volume than in the state of the art, since the fixing stud 2-11 occupies no volume in the zone ZL1.
