Description

The invention relates to a motor vehicle component arrangement for assembling an outer skin element and a method for producing such a motor vehicle component arrangement.

Out DE 101 16 283 B4 an arrangement for precisely fitting an add-on part on a basic component is known, in particular for the arrangement of a radiator grille on a bumper cladding of a motor vehicle. In this arrangement, separate devices for positioning and securing the attachment, one behind the other in the assembly direction, are provided, with at least one channel running transversely to the assembly direction and open in the assembly direction to accommodate a strip-shaped projection of the attachment or basic component is. In connection with this arrangement, no solution is disclosed for how a motor vehicle component arrangement can then be produced in a simple and high-quality manner when an outer skin element of a motor vehicle is to be attached to several components, in particular when the outer skin element is to be adjacent to visible joints Has outer skin elements.

The invention is based on the object of providing a motor vehicle component assembly for assembling an outer skin element and a method for producing such a motor vehicle component assembly with which the preparation of the later assembly of an outer skin element on the motor vehicle component assembly is made easier and qualitatively improved.

The object is achieved according to the invention with the features of the independent claims. Further practical embodiments and advantages of the invention are described in connection with the dependent claims.

According to a motor vehicle component arrangement according to the invention, a first component is fixed relative to a second component opposite at least one fixing element, the at least one fixing element being an element that differs from the first component and the second component, in particular a body panel of a motor vehicle. A guide opening is provided on the first component, and a projection cooperating with the guide opening is provided on the second component. The projection and the guide opening are matched to one another in such a way that the interaction of the guide opening and the projection limits the relative alignment of the first component to the second component during assembly and the relative position of the projection within the guide opening is visible in the assembled state.

The above interaction means that the projection can be arranged in such a way that it at least partially engages in the guide opening and thereby the absolute mobility of the first component relative to the second component is restricted by the projection “caught” in the guide opening. The coordinated design of the first component with guide opening and of the second component with a corresponding projection makes it easier to align the two components relative to one another during assembly and in particular until the components are fastened. This design can make it easier for assembly personnel, in particular, to avoid errors in the relative alignment of the components to one another, to identify preparatory work that is not dimensionally accurate or components and other elements, and to check the quality of the assembly work. The check can take place not only during the assembly itself, but also at a later point in time until an outer skin element is assembled on the first component and the second component in a later production section and then covers the guide opening and the projection arranged in it. The motor vehicle component arrangement according to the invention thus makes it possible to facilitate the preparation for the subsequent assembly of an outer skin element on the motor vehicle component arrangement, to check it and, if necessary, to correct it and thus improve it qualitatively.

The coordination is preferably such that in the event of relative movements between the first component and the second component during assembly, at least one translational degree of freedom and / or at least one rotational degree of freedom is blocked. It is particularly preferred if, due to the coordination between the guide opening and the projection, only one translational degree of freedom or a combination of a translational degree of freedom and a rotational degree of freedom remains.

It is also preferred if the projection and the guide opening are matched to one another in such a way that a relative alignment of the first component relative to the second component is ensured in such a way that mutual support in the direction of gravity (i.e. in the vertical direction of the vehicle / z-direction) is ensured. This can be done in particular that the displacement of the projection in a predetermined displacement direction up to a stop simultaneously brings the first component and the second component into contact so that a target position is between the first component and a stop element as well as between the first component and a second component results.

In a further practical embodiment of a motor vehicle component arrangement according to the invention, the projection and the guide opening are matched to one another in such a way that the first component and the second component can only be moved relative to one another on a predetermined guide path during assembly. This means both linear guideways (linear guide) and any other curved guideways. In practice, however, linear guideways are preferred, since with such guideways a desired rotational target alignment of the first component relative to the second component can be ensured and thus an important prerequisite for a later, precise assembly and alignment of an outer skin element is created, which in particular is required for high-quality visible joints with small and constant gap dimensions.

A motor vehicle component arrangement according to the invention can be implemented in a simple and cost-effective manner in terms of production technology if the guide opening is configured as an elongated hole and a web extending in the width direction is configured as a projection. Such a design can be integrated into a production mold for plastic injection molded parts without additional effort and without the need for post-processing work, so that - in the case of the construction of new parts for which new molded parts have to be produced anyway - virtually no additional costs due to the provision of a guide opening and a corresponding lead arise.

Further advantages in a motor vehicle component arrangement according to the invention result when the longitudinal direction of the elongated hole of a guide opening with an elongated hole is oriented perpendicular to a stop contour of a stop element and the projection is designed such that the first component can only be displaced perpendicular to this stop contour. This applies in particular to stop contours in the form of linear edges that are themselves part of a joint or are formed parallel to a joint edge. In this case, by aligning the guide opening vertically and designing the projection in such a way that relative mobility between the first component and the second component is only possible in one translational direction during assembly, it can be ensured that the relative rotational alignment of the first component is correct relative to the second component and also relative to the stop contour.

If in a motor vehicle component arrangement according to the invention in the area of the first component surrounding the guide opening a marking of a target position area is provided for the projection, a visual inspection can be carried out both during and after assembly and it can be checked whether the first Component relative to the second component are arranged within a target position tolerance (target position range). If this is not the case, a check can be made as to whether the at least one fixing element, the first component and / or the second component were not manufactured to the correct dimensions or whether there is another previous assembly error. In this context, it is particularly advantageous that the visual inspection makes it possible to carry out subsequent corrections before an outer skin element is to be mounted on the first component and the second component in a later assembly step. As a result, a complication-free and dimensionally accurate assembly of the outer skin element can be ensured and the productivity in production can be significantly improved. The marking of a target position area can be done in particular by two lines, arrows, elevations, e.g. in the form of ribs, or in some other way. Markings are preferred that are already created during the production of the first component without further work steps or those that can be created easily and inexpensively afterwards, e.g. engraving, mechanical or chemical material processing, application of paint, etc.

Further advantages result if the first component and the second component of a motor vehicle component arrangement according to the invention are both designed as a fastening unit for an outer skin element. This means that the first component and the second component themselves are already prepared for a later assembly of an outer skin element. This can in particular be implemented by a suitable geometric design of the first component and / or the second component.

In this context, reference is made only as an example to the possibility that one or more coupling elements for fastening the outer skin element can be provided or formed in one piece on the first component and / or on the second component. This means in particular hook-like elements, as well as latching element receptacles and latching elements that are matched to correspondingly complementary latching elements or latching element receptacles on the outer skin element to be mounted. With regard to such locking elements, reference is made in particular to clip element receptacles and / clip elements known from practice, in particular in connection with plastic components, as they are known from automobile construction and from other technical fields. Against this background, reference is also made explicitly to a motor vehicle component arrangement according to the invention with an outer skin element clipped therewith. To avoid damage to such clip elements during assembly or subsequent repair and maintenance work May require dismantling and reassembly of the outer skin element to avoid and to keep the corresponding risk low, a precise alignment of the first component and the second component is of particular practical importance, especially when clip elements on both the first component and the second component and / or clip element recordings are provided.

The motor vehicle component arrangement according to the invention was made in particular in connection with a first component and / or a second component, which are screwed to one or more fixing elements, in particular one or more shell panels. It is accordingly advantageous if corresponding screw openings for screwing to a body element of a motor vehicle are provided on the first component and / or on the second component.

The invention also relates to a method for producing a motor vehicle component arrangement as described above with a first component and a second component, both of which are to be attached to at least one fixing element in such a way that they are oriented relative to one another so that in a subsequent Assembly step can assemble an outer skin element of the motor vehicle. The process includes the following process steps, which are also carried out in this order:

Reference is hereby made once again to the advantages already described in connection with the motor vehicle component arrangement, which - if applicable - also apply to the method.

Further practical embodiments of the invention are described below in connection with the drawings. Show it:

• 1 a motor vehicle component arrangement with a first component, a second component and a fixing element and a first outer skin element in a view from the rear,
• 2 a section of the in 1 Motor vehicle component arrangement shown with a second outer skin element covering the first component and the second component,

The 1-7 show various views and partial views of a motor vehicle component arrangement according to the invention 10 of a first component 12th relative to a second component 14th .

On the first component 12th is a guide opening 16 provided, and on the second component 14th is one on the guide opening 16 coordinated and with this guide opening 16 cooperative advance 18th intended. In the embodiment shown, the projection is 18th in one piece on the first component 12th educated.

In the arrangement shown 10 are the first component 12th and the second component 14th arranged such that the projection 18th into the guide opening 16 engages and due to the interaction of projection 18th and guide opening 16 the relative mobility of the first component 12th compared to the second component 14th during assembly through the guide opening 16 is limited. In the present case is the height of the projection 18th chosen to be about as large as the width of the guide opening 16 so that as an assembly aid for the relative alignment of the first component 12th relative to the second component 14th results in a linear guide. As long as the first component 12th is not yet attached, but initially relative to the second component during assembly 14th must be positioned, it can be arranged according to the arrangement of the projection 18th so that it goes into the guide opening 16 engages, only in the direction of the longitudinal extent of the Guide opening 16 move, ie move purely translationally in one direction. This means that all rotational degrees of freedom and all translational degrees of freedom with the exception of one translational degree of freedom are blocked.

In 1 are the first component 12th and the second component 14th already shown in their target position in the assembled state. The first component 12th is by means of screw connections 20a , 20b especially compared to a first fixing element 28 serving outer skin element 22nd in the form of a side part 24 set, the screw connections 20a , 20b lie in the area of a flap that is not itself part of the outer skin of the motor vehicle. By means of another screw connection 20c the first component is also opposite to a second fixing element 26th serving shell sheet set. The screw connection 20c as well as two further screw connections 20d , 20e also serve the second component 14th compared to the second fixing element 26th (Shell sheet).

As in 2 can be seen, serve the first component 12th and the second component 14th in addition, an outer skin element 22nd in the form of a bumper cover 30th to attach, with one located between the bumper panel 30th and the side part 24 extending visible joint 34 high quality requirements with regard to the joint width and the course of the joint (variation of the width over the length) are made.

On the second component 14th is on the top a coupling element - here designed like a hook 32 formed, which serves to be an outer skin element 32 relative to at least one other outer skin element 22nd to fix and position.

The assembly of the in 1 Motor vehicle component arrangement shown 10 runs as follows: In a first process step, the second component is 14th , here a lateral guide profile with the screws 20d , 20e compared to the fixing element 26th set. With the fixing element shown 26th it is a shell sheet in the form of a further guide profile to which a headlight can in particular already be attached.

Then the first component 12th relative to the second component 14th arranged such that the projection 18th of the second component 14th into the guide opening 16 of the first component 12th protrudes.

Then the first component 12th translationally in the longitudinal direction relative to the second component 14th Shifted until the left edge with the edge of the side part serving as a stop contour 24 comes to a stop. The side part 24 is a stop element in the sense of the invention. The longitudinal direction of the guide opening 16 is oriented so that the edge of the side part 14th and the left side of the first component 12th are aligned parallel to each other and in one by the interaction of projection 18th and guide opening 16 performed relative movement of the first component 12th to the second component when hitting a predetermined target position is reached. In a final process step, the first component with the screws 20a , 20b , 20c with the side part 24 or with the fixing element 26th (Shell sheet) screwed, the screw 20c also for simultaneous and additional fastening of the second component 14th compared to the fixing element 26th is being used.

The features of the invention disclosed in the present description, in the drawings and in the claims can be essential both individually and in any combination for the implementation of the invention in its various embodiments. The invention can be varied within the scope of the claims and taking into account the knowledge of the competent person skilled in the art.
