Description

1 INSERT DE PRE MAINTIEN D'UN SUPPORT DE COMPOSANT SUR LA STRUCTURE D'UN VEHICULE La présente invention concerne un insert de pré maintien pour maintenir sur une structure de carrosserie, un support de réception d'un composant, en préalable à sa fixation. Dans l'état de la technique, nous connaissons le document FR2780459 qui décrit un système de fixation comprenant un carter comportant un canal, une vis engagée dans le canal et possédant, à distance de sa tête, une embase évasée destinée à venir en appui contre la surface d'un support, une rondelle engagée sur la vis et un organe élastique apte à maintenir ladite rondelle sur la vis entre la tête et l'embase évasée, avec déplacement relatif autorisé entre la rondelle et la vis, ledit organe élastique étant lui-même adapté pour coopérer par complément de forme avec le canal du carter. De plus, l'extrémité inférieure de l'organe élastique est prolongée par une collerette fendue axialement sous forme de trois secteurs équirépartis. Cette collerette présente un pouvoir de déformation radiale important tout en présentant une rigidité axiale significative. Ainsi, la vis peut se déplacer axialement mais la partie évasée de l'embase vient en butée contre la collerette et assure un positionnement de la 3033181 2 vis sensiblement dans l'axe du canal. Dans le système de fixation décrit l'organe élastique limite uniquement le déplacement axial de la vis, sans qu'elle soit pré positionnée ou pré 5 maintenue dans une position déterminée. Le but de l'invention est donc de proposer un insert de pré maintien apte à assurer la tenue d'un support sur une structure avant sa fixation. Le support étant destiné à recevoir 10 des composants immobilisés par clippage. A cet effet, la présente invention a pour objet un insert de pré maintien d'un élément de support sur une partie de structure de véhicule, avant sa fixation, le support devant accueillir 15 un composant clippé, l'insert de pré maintien étant solidarisé à l'élément de support par l'intermédiaire d'un élément amortissant dans lequel l'insert de pré maintien est monté serré.BACKGROUND OF THE INVENTION The present invention relates to a pre-holding insert for holding on a body structure, a support for receiving a component, prior to its attachment. In the state of the art, we know the document FR2780459 which describes a fastening system comprising a housing having a channel, a screw engaged in the channel and having, at a distance from its head, a flared base intended to bear against the surface of a support, a washer engaged on the screw and an elastic member adapted to hold said washer on the screw between the head and the flared base, with relative movement allowed between the washer and the screw, said elastic member being -Even adapted to cooperate by complementary form with the crankcase channel. In addition, the lower end of the elastic member is extended by an axially split flange in the form of three equidistributed sectors. This collar has a high radial deformation power while having significant axial stiffness. Thus, the screw can move axially but the flared portion of the base abuts against the flange and ensures a positioning of the screw 30 substantially in the axis of the channel. In the fastening system described the elastic member limits only the axial displacement of the screw, without it being pre-positioned or pre-held in a determined position. The object of the invention is therefore to provide a pre-holding insert adapted to ensure the holding of a support on a structure before fixing. The support is intended to receive components immobilized by clipping. For this purpose, the subject of the present invention is an insert for pre-holding a support element on a part of a vehicle structure, before its attachment, the support having to accommodate a clipped component, the pre-holding insert being secured to the support member via a damping element in which the pre-holding insert is mounted tightly.

20 Avantageusement, l'insert comporte depuis une ouverture traversante, trois lamelles équidistantes dirigées axialement et progressivement vers le centre de l'ouverture.Advantageously, the insert comprises, from a through opening, three equidistant lamellae directed axially and progressively towards the center of the opening.

25 Suivant une autre caractéristique avantageuse, l'extrémité des lamelles comporte des ergots.According to another advantageous characteristic, the ends of the lamellae comprise lugs.

3033181 3 Suivant une autre caractéristique, les lamelles de l'insert sont engagées sur le filetage d'un goujon solidaire de la structure du véhicule.According to another feature, the lamellae of the insert are engaged on the thread of a stud integral with the vehicle structure.

5 Avantageusement, l'ergot est dirigé vers l'axe longitudinal de l'insert. Selon une variante, l'ergot est dimensionné pour se caler en direction du fond de filet du 10 filetage du goujon. Selon une autre variante, la paroi de l'ouverture traversante est plus épaisse entre les lamelles.Advantageously, the lug is directed towards the longitudinal axis of the insert. According to a variant, the lug is dimensioned so as to be wedged in the direction of the thread bottom of the thread of the bolt. According to another variant, the wall of the through opening is thicker between the lamellae.

15 Selon une autre variante, l'insert comporte une paroi externe cylindrique. Avantageusement, l'insert comporte à sa base 20 une collerette dirigée vers l'extérieur. Selon une autre caractéristique, l'insert est fabriqué en matière plastique.According to another variant, the insert has a cylindrical outer wall. Advantageously, the insert comprises at its base 20 a flange directed outwards. According to another characteristic, the insert is made of plastic material.

25 Par ailleurs, l'invention a également pour objet, un élément de support pré maintenu par au moins trois éléments amortissants solidaire de trois inserts, suivant les caractéristiques susmentionnées.Furthermore, the invention also relates to a support element pre-held by at least three damping elements integral with three inserts, according to the aforementioned characteristics.

L'extrémité libre des lamelles 15 comporte des ergots 16 adaptés pour venir en prise dans le filetage du goujon 7 et pour se caler en direction du fond de filet 19a du filetage 19 du goujon 7. La paroi du passage 2d est 20 plus épaisse entre les lamelles 15. La hauteur de l'élément amortissant 4 est équivalente à la hauteur de l'insert 2. L'insert 2 est fabriqué en matière plastique tandis que l'élément amortissant 4 en matière élastomère permettant d'absorber les 25 vibrations. Avantageusement, quand le support 1 est engagé sur les goujons 7, il est pré maintenu efficacement par les inserts 2 et les écrous de blocage 18 peuvent être introduits sans difficultés pour réaliser la fixation définitive du support 1, 30 en serrant l'extrémité inférieure de l'insert 2 sur la paroi de la structure 3 tandis que l'extrémité 3033181 7 supérieure est directement immobilisée par l'écrou 18. Ensuite, les différents composants 9, 10, 11 (visible figure 1) sont facilement montés par une opération de clippage, par l'opérateur.Further features and advantages of the invention will become apparent from the following description, given by way of example with reference to the accompanying drawings, in which: FIG. 1 is a schematic perspective view of a mounting scenario showing the stack of a support member on a vehicle structure part and the components coming to clip on the support, according to the invention; - Figure 2 is a schematic perspective view of a pre-holding insert 15 engaged on a stud secured to a damping element mounted in a shaft of the support; FIG. 3 is a diagrammatic plan section of a lamella of the insert engaging in a thread of the thread of a stud, according to the invention. FIG. 1 is a schematic perspective view of a mounting scenario showing the stack of a support member 1 on a vehicle structure part 3 and the components 9, 10, 11 clipping onto the support 1, according to the invention. The structural part 3 of the vehicle is an apron provided with a soundproofing element 6. This structural element 3033181 5 3 comprises three studs 7 welded to the wall of the structure 3. Circular openings 8 are provided around the studs 7 in order to position the inserts correctly. The studs 7 are arranged in equilateral triangles or two 7a, 7b in the lower position on a substantially horizontal line and the last 7c, above on a center line passing between the two studs 7a, 7b. The support element 1 is equipped with inserts (not visible) themselves mounted in damping elements (not visible). The support member 1 comprises arrangements or drums 13 for mounting the damping elements 15 having the inserts. When the support member 1 is attached, the components which are a computer box 9, a relay box 10 and an alarm box 11 are successively clipped by appropriate means provided for this purpose. FIG. 2 is a diagrammatic perspective view of a pre-holding insert 2 engaged on a stud 7, integral with a damping element 4 mounted in a drum 13 of the support 1. The damping element 4 is cylindrical, it possesses an external groove 4a which abuts on a rim 13b of the cylindrical opening 13a of the drum 13 constituting the support 1. The damping element 4 comprises a cylindrical passage 4b provided with a counterbore at its base. The insert 2 having a cylindrical outer wall 2a has at its base an outer rim 2b. The insert 2 is force-fitted into the cylindrical passage 4b of the damping element 4. The external rim 2b of the insert 2 abuts in the counterbore at the base of the damping element 4. The stud 7 comprising a thread and a chamfer at its end is fixed by welding 14 to the right of 10 the wall of the structure 3 of the vehicle. The insert 2 comprises, from a through opening 2c forming a passage 2d, three equidistant lamellae 15 directed axially and progressively towards the center of the opening in the direction of the axis 16. The free end of the lamellae 15 comprises lugs 16 adapted to engage the thread of the stud 7 and to wedge towards the thread root 19a of the thread 19 of the stud 7. The wall of the passage 2d is thicker between the lamellae 15. The height of the damping element 4 is equivalent to the height of the insert 2. The insert 2 is made of plastic while the damping element 4 of elastomeric material for absorbing vibration. Advantageously, when the support 1 is engaged on the studs 7, it is pre-held effectively by the inserts 2 and the locking nuts 18 can be introduced without difficulty to achieve the final fixing of the support 1, 30 by tightening the lower end of the insert 2 on the wall of the structure 3 while the upper end is directly immobilized by the nut 18. Next, the various components 9, 10, 11 (visible in FIG. 1) are easily mounted by an operation of FIG. clipping, by the operator.
