Description

The present disclosure relates to an assembly for a motor vehicle and/or a motor vehicle comprising the assembly.

It is known to attach retaining strips for a sill or other structural components to the body of a motor vehicle using, for example, expanding rivets. The expanding rivets are inserted into holes in the body and are used to fix and align the respective retaining strip or the respective structural component.

However, due to the holes, the body is not waterproof or does not meet the watertightness requirements. In addition, the alignment of the respective retaining strip or the respective structural component is too imprecise.

document DE 26 07 154 A1 describes a flange connection for frames, in particular vehicle chassis, in which the individual profiles forming the frame can be screwed together via prefabricated flange points. The profile legs that lie against one another in the area of the flange points have deformations that are approximately congruent with one another, of which the convex deformation area of one profile leg engages in the concave deformation area of the other leg and the interlocking deformations support one another at least in places.

document DE 10 2018 127 375 A1 describes a sill of a vehicle body, which comprises a lower sill part and an upper sill part, which is placed on the lower sill part and fastened to it. The upper sill part is part of a vehicle structure, wherein a recess is provided in one side of a first sill part, which faces the further sill part, and a projection is provided on one side of the further sill part, which faces the first sill part. The shape of the recess corresponds to the shape of the projection and the projection engages in the recess in a form-fitting manner.

document DE 10 2014 105 973 A1 describes a system comprising a sill panel and a fastening clip for fastening the sill panel to a body part of a vehicle. The sill panel has a locking hook and the fastening clip has a locking receptacle for receiving the locking hook and holding means for holding it to the body part. The locking receptacle also has an elastic holding arm which, when the locking hook of the sill panel is received in the locking receptacle, exerts a holding force on the locking hook through its spring preload, which counteracts the sill panel from coming loose from the fastening clip.

Against the background of this prior art, the object of the present disclosure is to provide a device which is each suitable for enriching the prior art.

The problem is solved by the features of the independent claims. The subordinate claims and the dependent claims each contain optional further developments of the disclosure.

The task is then solved by an assembly for a motor vehicle.

The assembly comprises a body component, wherein a side surface of the body component has at least one body connection section. The assembly comprises a trim component and a structural component for fastening the trim component to the body component, wherein a side surface of the structural component has at least one structural connection section.

The at least one body connection section has a cylindrical fastening element and at least one recess which is formed at a distance from the fastening element.

The at least one structural connection section has a passage for receiving the fastening element and at least one elevation for positively receiving it in the at least one recess. The at least one elevation is spaced apart from the passage and in sections is designed to correspond in shape to the at least one recess.

The assembly described above offers a number of advantages. Among other things, the assembly offers a connection concept for attaching (or connecting) the structural component to the body component without the use of expanding rivets or other fastening devices that have to be guided through openings in the body component. The body component therefore does not have to have any openings through which water or leaks can penetrate. In other words, the body component can be watertight and, for example, designed as part of a dry room. In addition, no additional seals on the body component are necessary.

Furthermore, it is possible to provide at least one recess on the body component and at least A raised portion on the structural component advantageously makes it possible to align the structural component automatically and as precisely as possible to the body component during assembly, so that, for example, the body component and the structural component are aligned parallel to one another.

Possible further developments of the device described above are explained in detail below.

The at least one recess can be formed by embossing. The at least one recess can be formed, for example, as a non-continuous joint and/or non-continuous groove.

The at least one body connection section and/or the body component can be designed without holes.

The cylindrical fastening element can be formed by a threaded bolt that is attached to the side surface of the body component (e.g. without holes), optionally welded. The structural component can be screwed (or clamped) or screwed (or clamped) to the body component using the threaded bolt and a nut.

At least one elevation can be designed as a rib.

The at least one recess may have a semicircular, triangular or polygonal cross-section.

The at least one elevation can have a shape which is at least partially formed corresponding to the cross section of the at least one depression.

The at least one recess can be formed along a longitudinal direction of the body component at a distance from the cylindrical fastening element.

The at least one elevation can be formed along a longitudinal direction of the structural component at a distance from the passage.

The at least one structural connection section may have at least one straight reinforcing rib which runs perpendicularly between the passage and the at least one elevation.

The at least one straight reinforcing rib can additionally be formed on a second side surface of the structural component, which is opposite the side surface of the structural component.

At least one curved reinforcing rib may be formed on the second side surface. The at least one curved reinforcing rib may be arranged opposite to the at least one elevation. Ends of the at least one curved reinforcing rib may be connected to the at least one straight reinforcing rib.

The at least one recess can comprise a first recess and a second recess. The first recess can be formed along a longitudinal direction of the body component in front of the cylindrical fastening element and the second recess can be formed along the longitudinal direction after the cylindrical fastening element. The cylindrical fastening element can be arranged centrally between the first recess and the second recess.

The at least one elevation can comprise a first elevation and a second elevation. The first elevation can be formed along a longitudinal direction of the structural component before the passage and the second elevation can be formed along the longitudinal direction after the passage. The passage can be arranged centrally between the first elevation and the second elevation.

The assembly can form a sill or part of a sill for the motor vehicle. The assembly can also be referred to as a dry sill, for example.

The body component can have a cavity or form a cavity with one or more other (body) components. The cavity can be designed as a dry space.

The structural component can be designed as a strip. The structural component can also be referred to as a retaining strip (for the trim component on the body component).

The at least one recess and the at least one elevation can be designed (by the positive reception of the at least one elevation in the at least one recess) for the automatic, optionally parallel, alignment of the structural component on the body component.

The passage may have a larger diameter than the cylindrical fastening element. The passage may be designed to pre-position the cylindrical fastening element and/or to compensate for a position tolerance of the cylindrical fastening element.

The at least one depression (and/or a longitudinal direction of the at least one depression) can extend in the longitudinal direction of the body component. The cross section can extend transversely to the longitudinal direction of the at least one depression.

The at least one elevation (and/or a longitudinal direction of the at least one elevation) can extend transversely to a longitudinal direction of the structural component.

The structural component can have at least one fastening section for fastening, e.g. clamping and/or clipping, the cladding component to the structural component. The fastening section can extend, e.g., along a longitudinal edge of the structural component and/or run at least in sections perpendicular to the side surface of the structural component. An edge of the cladding component can be clamped and/or clipped (or clamped and/or clipped) on or in the fastening section.

The above can be summarized in other words and in a possible more concrete embodiment of the disclosure as described below, whereby the following description is not to be interpreted as limiting the disclosure.

According to the present disclosure, the structural component, which can also be referred to as a retaining strip, for example, can be attached or attachable to bolts welded on the outside. The alignment of the structural component can be achieved by a positive connection between the body component and the structural component. No holes in the body component are necessary, and the alignment of the structural component can be achieved automatically during screwing or clamping.

For example, such a sill system can be connected or attached to a side frame of a motor vehicle.

Furthermore, a motor vehicle is provided, wherein the motor vehicle comprises the assembly described above.

The motor vehicle may be a passenger car, in particular an automobile, or a commercial vehicle, such as a truck.

What is described above with reference to the assembly also applies analogously to the motor vehicle and vice versa.

Below, optional embodiments are described with reference to 1 to 8 described.

• 1 and 2 show schematically a known assembly;
• 3 shows schematically an assembly according to the disclosure;
• 4 schematically shows a body connection section according to an embodiment;
• 5 and 6 schematically show a structure connection section according to several embodiments; and

• 8 shows a schematic assembly process of the module.

The 1 and 2 show a known assembly according to the prior art. The assembly comprises a body component 101, a structural component 102 and a trim component 103.

The structural component 102 is used to fasten the trim component 103 to the body component 101. For this purpose, the structural component 102 is fastened to the body component using expanding rivets 104. Each of the expanding rivets 104 is guided through a bolt passage 105 in the body component 101 and a bolt passage 106 in the structural component 102. The expanding rivets 104 are therefore not only used for fastening, but also for aligning the structural component 102 to the body component 101.

Due to the bolt passage 105, water or a leak can penetrate into the body component 101. Furthermore, the alignment of the structural component 102 during the assembly process using the expanding rivets 104 is only imprecise.

3 shows only schematically the assembly 50 according to the disclosure, which can form, for example, a sill or part of a sill for a motor vehicle. The assembly 50 comprises a body component 1, a structural component 2 and a trim component 3, wherein the structural component 2 serves to fasten the trim component 3 to the body component 1. Nuts 4 can also be used for fastening.

A side surface of the body component 1, which faces the structural component 2 in the assembled state of the component 50, has at least one body connection section 10, e.g. two body connection sections 10.

Such a body connection section 10 is in 4 shown enlarged, which is formed on the side surface 1A of the body component 1.

The body connection section 10 has a cylindrical fastening element 11 and at least one recess 12 which is formed at a distance from the fastening element 11, for example along a longitudinal direction of the body component 1.

The cylindrical fastening element 11 can be formed by a threaded bolt that is fastened, e.g. welded, to the side surface 1A of the body component 1. It is therefore not necessary for the threaded bolt or another component to be guided through a passage in the body component 1. The body connection section 10 and/or the body component 1 can therefore be designed without holes, for example.

The at least one recess 12 can, as in 4 shown, comprise a first recess 12 and a second recess 12, wherein the first recess 12 is formed along a longitudinal direction of the body component 1 in front of the cylindrical fastening element 11 and the second recess 12 is formed along the longitudinal direction after the cylindrical fastening element 11. In other words, the first recess 12 and the second recess 12 can be arranged symmetrically (and thus at the same distance) to the cylindrical fastening element 11 along the longitudinal direction of the body component 1.

In the embodiment shown, the at least one depression or the first depression 12 and the second depression 12 each have a triangular (or pyramid-like) cross-section. Alternatively, other cross-sections are also conceivable, e.g. a semicircular or polygonal cross-section.

Furthermore, a side surface 2A of the structural component 2, which faces the body component 1 in the assembled state of the component 50, has at least one structural connection section 20, e.g. structural connection sections 20.

Two embodiments of such a structure connection section 20 are shown in the 5 and 6 shown enlarged.

The structural connection section 20 has a passage 21 for receiving the fastening element 11 and at least one elevation 22-1, 22-2 for positively receiving it in the at least one recess 12. The at least one elevation 22-1; 22-2 is spaced apart from the passage 21, e.g. along a longitudinal direction of the structural component 2, and in sections is designed to correspond in shape to the at least one recess 12.

The at least one elevation 22-1; 22-2 can, as in the 5 and 6 shown, comprise a first elevation 22-1; 22-2 and a second elevation 22-1; 22-2, wherein the first elevation 22-1; 22-2 is formed along a longitudinal direction of the structural component 2 in front of the passage 21 and the second elevation 22-1; 22-2 is formed along the longitudinal direction after the passage 21.

The at least one elevation or the first elevation 22-1, 22-2 and the second elevation are designed as a rib and each further have a shape which is formed at least in sections corresponding to the cross section of the at least one depression 12. In 5 the two elevations 22-1 each have a triangular shape, corresponding to the cross section of the depressions 12 in 4 Alternatively, the two surveys 22-2 in 6 Each has a triangular shape. Other shapes are also conceivable, such as a polygonal shape.

As in the 5 and 6 Further shown, the structural connection portion 20 may include at least one straight reinforcing rib 23 extending perpendicularly between the passage 21 and the at least one elevation 22-1, 22-2, e.g., a first straight reinforcing rib 23 between the passage 21 and the first elevation 22-1, 22-2 and a second straight reinforcing rib 23 between the passage 21 and the second elevation 22-1, 22-2.

7 schematically shows a section of the structural component 2 opposite the structural connection section 20. As shown, the at least one straight reinforcing rib 23, e.g. the first and second reinforcing rib 23, can additionally be formed on a second side surface 2B of the structural component 2, which is opposite the side surface 2A of the structural component 2. In the assembled state of the component 50, the second side surface 2B faces away from the body component 1 or faces the trim component 3.

Furthermore, at least one curved reinforcing rib 25 can be formed on the second side surface 2B, wherein the at least one curved reinforcing rib 25 is arranged opposite to the at least one elevation 22-1, 22-2 and ends of the at least one curved reinforcing rib 25 are connected to the at least one straight reinforcing rib 23.

For example, a first curved reinforcing rib 25 may be provided opposite to the first at least one elevation 22-1; 22-2 and ends of the first curved reinforcing rib 25 are connected to the first straight reinforcing rib 23. Similarly, a second curved reinforcing rib 25 can be arranged opposite the second at least one elevation 22-1; 22-2 and ends of the second curved reinforcing rib 25 are connected to the second straight reinforcing rib 23. The two curved reinforcing ribs 25 and the two straight reinforcing ribs 23 can be formed symmetrically to the passage 21.

In the 5 to 7 it is further shown that the structural component 2 has at least one fastening section 24 for fastening, e.g. clamping and/or clipping, the cladding component 3 to the structural component 3. The fastening section 24 can, for example, extend along a longitudinal edge of the structural component 3 and, for example, run at least in sections perpendicular to the side surface 2A (or the side surface 2B).

8 shows schematically an assembly process of the assembly 50. As shown in (a), the structural component 2 is first roughly pre-positioned by receiving the cylindrical fastening element 11, e.g. a threaded bolt, in the passage 21 and then placing a nut 4 on the cylindrical fastening element 11.

The nut 4 is screwed until the structural component 2 rests against the body component 1, as shown in different cross-sectional views in (b) and (c). This results in the positive reception of at least one elevation, here for example the triangular elevation 22-1 in the recess 12, whereby the structural component 2 is automatically positioned on the body component 1 and aligned, e.g. parallel to the body component 1.

Thus, in contrast to the prior art, the structural component 2 is automatically and precisely aligned with the body component 1 during the screwing or clamping process. Furthermore, in contrast to the prior art, the body component 1 has no openings through which water can penetrate, so that the body component can be provided for forming a dry space.

Finally, the cladding component 3 can be fastened to at least one fastening section 24 of the structural component 2, for example by clamping and/or clipping an edge of the cladding component on or in the fastening section 24.
