Definitions

  • the present invention relates to a device for aligning a first vehicle component on a second vehicle component. Moreover, the present invention relates to a method for mounting the first vehicle component on the second vehicle component. In particular, the fixation of headlights should be simplified and improved in the vehicle final assembly.
  • a headlight lights unit for motor vehicles is known. From her a direction indicator is inserted through a first Zahnrichtgesperre to the headlight housing opposite to the direction of travel of the vehicle and aligned by a second Zahnrichtgesperre respect to the vehicle body transversely to the direction of travel.
  • Each locking mechanism consists of two mutually parallel spring arms with outwardly facing notches, which cooperate with detents of two opposite inner sides of a sleeve. One element has the sleeve and the two spring arms.
  • the publication DE 102 34 224 A1 discloses a lighting unit for vehicles with a housing which is connectable to a body part at at least three mutually spaced attachment points.
  • a first attachment point is formed as a fixed point with a fixing element, in such a way in that the housing is arranged in an attaching position so as not to be able to be set or only counter to the approach movement direction to the body part that has taken place.
  • the publication DE 10 2006 008 240 A1 describes a fastening device for a headlight on a vehicle, in which this is fastened with mounting parts on the vehicle body.
  • the fastening device is designed such that disassembly and repeated assembly of the headlight can be done without tools.
  • a first support member with the upper side member and a second support member with a front end mounting support of the vehicle is detachably connectable.
  • the first support member allows tolerance compensation in the X direction of the vehicle and the second support member allows tolerance compensation in the Y direction of the vehicle.
  • Both mounting parts are detachably arranged on quick attachment means in a defined position on the headlight.
  • the object of the present invention is therefore to improve the quality in terms of the gap dimensions in the vehicle final assembly and to reduce the adjustment effort.
  • this object is achieved by a device for aligning a first vehicle component on a second vehicle component, comprising a metallic carrier, a first plastic fitting element molded onto the metallic carrier, for accurately fitting into or onto the first vehicle component and a second plastic fitting element also molded onto the metallic carrier, for accurately fitting in or on the second vehicle component.
  • the invention provides a method for mounting a first vehicle component to a second vehicle component, by aligning the two vehicle components together by inserting a device described above with the first plastic fitting element to the first vehicle component and plugging the second vehicle component in or on the second plastic fitting of the device such that the second vehicle component is aligned with the first vehicle component, and securing the two vehicle components together.
  • the polymer hybrid method i. H. the sprinkling of plastic elements and in particular adjustment elements to a metal support
  • the polymer hybrid technology allows much tighter tolerances than previously common techniques.
  • the first plastic fitting element and the second plastic fitting element are each a pin or a pin.
  • the two plastic fitting elements may for example also be formed as bores.
  • the metallic support which carries the plastic mating elements or other vehicle components, for the purpose of adjustment easily inserted into the first vehicle component and so fixed at least in two directions.
  • the two plastic fitting elements are designed as pins, they can protrude in mutually opposite directions from the metallic carrier. Consequently, the vehicle components to be aligned with each other can be equipped with corresponding holes, pockets or stops for alignment.
  • the device according to the invention can be designed as a front end carrier according to a preferred embodiment. In this case, it not only has the function of alignment, but also this second function of the wearer of the front end.
  • the metallic carrier is a high-profile element formed by hydroforming.
  • the entire device can be in a single tool. It then finds not only a hydroforming (IHU), z.
  • IHU hydroforming
  • a tube instead, but also according to the polymer hybrid method, an encapsulation of the tube with plastic or a molding of the plastic mating elements.
  • At least a third plastic fitting element can be molded onto the device according to the invention for aligning the vehicle components.
  • other vehicle components can be aligned to the first and second vehicle component.
  • the device with the first or second plastic fitting element is additionally plugged into a third vehicle component.
  • the front-end module to which a headlight is already fastened with the aid of the first plastic fitting element, additionally attaches a fender to the second plastic fitting element on a longitudinal member of the vehicle and to the second plastic fitting element.
  • the headlamp is clearly positioned opposite the fender, but both are also in a well-defined position relative to the side member.
  • Figure 1 is a partial view of a motor vehicle in the headlight.
  • Fig. 2 is a schematic diagram of the inventive alignment of a
  • Headlamps and a fender on the side members of a vehicle and
  • Fig. 3 is a schematic diagram of a portion of a front end carrier according to the invention.
  • the starting point for the present invention is the improvement of the quality with respect to the gap dimensions in the final vehicle assembly.
  • Fig. 1 the left front of a motor vehicle is shown. It is there the headlight 1 and the fender 2 recognizable. In addition, adjacent to the headlight, the radiator hood 3 and the bumper fascia 4. Between the headlight 1 and the surrounding vehicle components, namely fender 2, cooling hood 3 and bumper fascia 4, a gap 5 is provided. The aim is to make this gap 5 in particular between the headlight 1 and the fender 2 over the entire length as wide as possible. Ie. The gap size should have a high quality.
  • a defined mounting receptacle is created in the fender bench on the vehicle body shell as a reference point.
  • Fig. 2 shows this the basic structure of a vehicle front.
  • the mounting receptacle 8 of the fender bank is shown enlarged. For clarity, however, the side member 7 is not shown there with the fender bank.
  • a front end support 9 is to be mounted on the side members 7. It consists essentially of a tube 10, which is formed by hydroforming (IHU) and represents a metallic carrier. In addition, plastic elements 11 are molded onto the tube 10 in an injection molding process. In this case, two plastic pins 12 and 13 are molded onto the tube 10.
  • the front end support 9 is thus a polymer hybrid component. Since the pins 12, 13 are formed from plastic by the relatively accurate injection molding, very small tolerances result. These small tolerances are now used to align the front end support 9 very precisely on the fender or the side member 7. This is done simply by the plastic pin 12 is inserted into the bore of the receptacle 8.
  • the mounting receptacle 8 forms a zero reference not only for the front end support 9, but also for the headlight 1, because of the metallic support, ie the tube 10 of the front end support 9, and the further plastic pin 13 is molded. This can be better seen in the enlarged view of FIG. 3.
  • a headlight receptacle 14 of the headlamp 1 is inserted on the plastic pin 13, a headlight receptacle 14 of the headlamp 1 is inserted.
  • the headlamp receptacle 14 is shown in Fig. 3 only as a beam without the headlamp body itself.
  • the mounting receptacle 8 thus determines the position of the headlight 1 via the front carrier 9.
  • the zero reference of the fender bank 7 is passed on to the headlight 1 via the pins 12 and 13. Due to the low Tolerances in plastic injection molding so the headlight 1 can be positioned very accurately.
  • a plastic pin 13 is directed in the direction of travel of the vehicle to the front and a plastic pin 12 to the rear. Both pins are parallel to each other, as the reference line in Fig. 3 illustrates.
  • the rearwardly directed plastic pin 12 is here designed so that it not only extends into the mounting receptacle 8 of the fender or the longitudinal member 7, but that at its free end even a fender receptacle 15 of a fender 16 can be plugged. This, too, can be better seen in FIG. 3, where the representation of the fender 16 itself is dispensed with.
  • the rearwardly directed plastic pin 12 thus also serves for aligning or positioning the fender 16.
  • the vehicle components longitudinal member 7, fender 16 and headlight 1 to each other have a precisely defined position. Even the front end support 9 itself, which serves as an alignment device for these vehicle components, thus has its defined position relative to these vehicle components.
  • the production of the pins can be integrated into the production process of the cross member or of the front end support.
  • the tube or the metallic carrier is formed in a single tool and molded with plastic. This also creates the plastic matching elements for aligning the vehicle components to each other, in particular of the headlamp 1 relative to the fender 16.
  • the manufacturing process thus leads to a metal-plastic hybrid component in which the pins and the cross member are integrally connected.
  • the hydrofluorocarbon polymer hybrid offers significant tolerances advantages since it can be manufactured with a single tool, eliminating reloading of a support member. All dimensions are made relative to an alignment point in the combined manufacturing process (molding, punching and injection molding). As a result, low repeat tolerances in the carrier of about +/- 0.1 mm are possible. In contrast to a solid plastic part, there is only minimal thermal distortion in the case of an IHU polymer hybrid part. In addition, no reshaping as usual metal parts, no overspray, no provision of the sheet thickness tolerance and no springback after tool removal is necessary or given. With the help of the front end support according to the invention, which also serves as a device for aligning vehicle components, an improved automatic assembly of the assembly front end is possible.
  • the bore in the mounting receptacle 8 of the longitudinal member can be detected and thus the installation of the front end can be performed accurately, since this hole is practically the reference point for the entire front end.
  • a setting of the headlights can be omitted relative to the fender, since the gap is already predefined by the plastic fitting elements.
  • the alignment device according to the invention in particular in the form of a hydrofluorocarbon hybrid part, can also be used for aligning other body parts, such as doors, flaps, lights, etc.
  • the device according to the invention can also be useful for the assembly of interior trim and interior components.

Abstract

L'alignement de deux composants d'un véhicule l'un par rapport à l'autre doit être amélioré et simplifié dans le montage final du véhicule. À cet effet, il est prévu un dispositif pour l'alignement d'un premier composant de véhicule (1) par rapport à un deuxième composant de véhicule (16). Ce dispositif présente un support métallique (10), un premier élément d'ajustage (13) en matière plastique qui est surmoulé sur le support métallique (10) pour s'ajuster précisément sur ou contre le premier composant de véhicule (1) et un deuxième élément d'ajustage (12) en matière plastique qui est également surmoulé sur le support métallique (10) pour s'ajuster précisément sur ou contre le deuxième composant de véhicule (16). De préférence, le dispositif prend la forme d'une traverse d'extrémité frontale (9) et peut s'enficher par l'un des éléments d'ajustage (12, 13) en matière plastique sur un longeron (7) du véhicule. Les éléments d'ajustage (12, 13) en matière plastique de la pièce hybride en polymère présentent des tolérances très serrées, ce qui permet d'atteindre une grande qualité, par exemple pour la cote de l'écart entre le projecteur et l'aile.
