Description

The invention relates to a body assembly for a motor vehicle, with the features of the preamble of claim 1.

Motor vehicles each have a bumper on the front and rear, in which a bumper cross member is usually connected to the vehicle chassis. In the event of a head-on or rear-end collision, the force is introduced into the chassis via the bumper cross member, which can be connected to longitudinal members of the chassis, for example. The corresponding connection can be provided via energy-absorbing elements such as crash boxes. In modern cars, the bumpers are usually optically integrated into the body, in that the bumper cross members are hidden behind an apron (front or rear apron) that is typically made of plastic. On the outside, only the apron can be seen, which is normally adapted to the adjacent body in terms of shape, surface structure and color. This means that the apron fits into the general surface shape of the body and cannot be distinguished from it in terms of color. Furthermore, sensors or other components can also be arranged behind the apron.

In the area in which the apron and the adjoining body part (usually a fender or side part) are adjacent to one another, there is no (visible) gap to the outside, i.e. these two components are seamlessly connected to one another. This has optical and aesthetic reasons. In practice, the gap size is typically mostly below 0.2 mm or 0.1 mm, although higher values can occur in sections. The apron is typically attached to at least one apron holder - also made of plastic - whereby the connection can be established, for example, by means of locking elements. The apron holder is in turn connected to the body, for example by screw connections or rivet connections.

When the vehicle is in operation, the apron moves relative to the adjacent body part (e.g. the fender or side panel) solely due to unavoidable vibrations within the bodywork and airflow. Due to the minimal gap, both parts either rub directly against each other or there is friction via dust and dirt particles that get between the two parts. In any case, the friction can damage and completely wear through the paintwork of the body part. This in turn leads to premature corrosion which can start locally and spread through the body panel until it is visible from the outside. The paintwork can even flake or flake off. Overall, the service life of the body part is reduced.

the CN 208134275 U discloses a bumper bracket for a motor vehicle. This has a through hole for a screw which is used for fastening to a vehicle body. On a side facing the body, a predominantly circular projection is formed which, in the assembled state, is supported on the body. In order to prevent water from collecting in the area of the screw, which would lead to corrosion, the projection has a recess through which water can run off from the area around the screw.

the US 2018/0029550 A1 discloses a body assembly for a vehicle having a body and a frame. The body assembly has an elongated bumper cross member and at least one body flange which is arranged along the bumper cross member and is configured to cover the body. Furthermore, at least one contact structure is arranged on an inner surface of the bumper cross member, which contact structure is configured to contact a section of the frame.

From the JP 2018/090068 A a bumper structure for a vehicle is known by which corrosion between different metals is to be prevented. A gap is provided between the license plate and a concave surface on the side of the bumper so that water droplets can flow down through the bumper. The water droplets then flow through a rectangular hole in the lower grille and are directed to the rear of the same. Since water is prevented from accumulating, the license plate can be prevented from corroding.

the KR 20070080911 A shows a bumper structure with a bumper cross member, which on the outside has a groove running in the transverse direction. A plurality of aluminum foam crash elements engage in the groove in a form-fitting manner. Each crash element is in turn framed together with the bumper cross member by a bracket which has a flange for mounting on the vehicle frame. On the outside, an energy-absorbing structure made of synthetic resin foam is provided, which in turn is covered by a plastic cladding.

In view of the prior art shown, the protection of a body part adjoining an apron from damage and corrosion still offers room for improvement.

The invention is based on the object of improving the protection of a body part adjoining an apron against damage and corrosion.

According to the invention, the object is achieved by a body assembly having the features of claim 1, the subclaims relating to advantageous embodiments of the invention.

It should be pointed out that the features and measures listed individually in the following description can be combined with one another in any technically meaningful manner and show further embodiments of the invention. The description additionally characterizes and specifies the invention, in particular in connection with the figures.

The invention provides a body assembly for a motor vehicle. The motor vehicle can in particular be a car, but also a truck. It can be said that the body assembly is assigned to a bumper which can be arranged on a vehicle front or a vehicle rear.

The body assembly has an apron and a metallic body part adjacent to it along a boundary line, which together form an outer surface of the motor vehicle. The apron is generally a cladding element, normally made of plastic, which covers the actual bumper on the outside. It can also be referred to as a bumper trim. Under certain circumstances, the apron can also have receptacles or frames for headlights, indicators or other lights and possibly a radiator grille. In general, the apron can be designed as a front apron or a rear apron. As a rule, the apron is designed as a pure cladding element, but it could optionally also have energy-absorbing additional elements on an inner side. In this context, it goes without saying that the cladding element formed by the apron also has certain, but only minor, energy-absorbing properties.

A metallic body part is adjacent to the apron along a boundary line. This is usually a front or rear fender or a side part of the motor vehicle. The body part is metallic, so it mainly consists of a metal, usually sheet steel. The boundary line corresponds to the outwardly visible course of the boundary between the apron on the one hand and the body part on the other. The geometric course of the boundary line depends of course on structural and design aspects of the motor vehicle and is normally neither straight nor even. The apron and the body part together form an outer surface of the motor vehicle, that is to say a surface that is visible from the outside. This is usually designed in a uniform color. For this purpose, the metallic body part has a suitable (multi-layer) paintwork which, in addition to the visual design, also serves to protect against corrosion. The color of the apron can be adapted to the paintwork of the body part, at least on the outside.

The apron is fastened to an apron holder which is fastened at least indirectly to the body part. The apron holder is normally connected to the body part by positive and / or non-positive connection means. For example, it can be screwed or riveted to the body part. The apron holder is preferably fastened directly to the body part, but fastening via an intermediate element would also be conceivable. In contrast to the body part, it is usually not made of metal but of plastic, e.g. ASA (acrylonitrile-styrene-acrylate copolymer) or PP-TD (polypropylene with talc). Since it is normally not visible from the outside, its color design is irrelevant. The apron holder in turn is used to fasten the apron, one could also say that the apron is held by the at least one apron holder and indirectly fastened to the body part by this. The apron can also be fastened to the apron holder by means of a form fit and / or force fit, for example by means of a latching connection. It goes without saying that in the case of an apron that adjoins opposing fenders or side parts on both sides of the vehicle, a separate apron holder is normally provided on each fender / side part.

According to the invention, at least one spacer element of the apron holder is interposed between the body part and the apron in a spacing direction running transversely to the direction of the boundary line in such a way that they are kept spaced apart from one another along the boundary line at least at the level of the spacer element. The at least one spacer element is part of the apron holder and is formed in one piece with it. It is usually molded along with other parts of the apron bracket during the manufacturing process. It is interposed between the apron and the body part, specifically along a spacing direction which runs transversely or perpendicularly to the direction of the boundary line. The direction of course corresponds to the course of the boundary line along the outer surface. Since the boundary line itself is generally not continuously straight, the direction of the course is generally local given direction, which can differ from one another at different points on the boundary line. The same applies to the direction of the distance, which is perpendicular to the direction of extension, but normally just like this, parallel to the outer surface. To simplify matters, one could also say that the respective spacer element is interposed transversely to the direction of the boundary line between the apron and the body part. The spacer element thus acts as a spacer between the body part on the one hand and the apron on the other hand. The geometry of the apron, the body part and the apron holder (in particular the spacer element) are matched to one another in such a way that the apron and the body part are kept at a distance from one another, which relates at least to an area at the height of the spacer element along the boundary line. In particular, in an area near the outer surface that is visible from the outside, a minimum gap dimension of at least 0.1 mm, at least 0.3 mm or at least 0.4 mm can be set. As will be explained further below, there can optionally be contact between the apron and the body part in areas that are offset along the boundary line to each spacer element, this contact usually being locally limited and over a small area. Overall, the body part and the apron are preferably kept at a distance from one another along the predominant part of the boundary line, for example along at least 80% of the total length.

Since direct contact between the body part and the apron is prevented (at least predominantly), there cannot be any friction between these two parts which could damage the paintwork of the body part. Although there is usually direct contact between the spacer element and the body part, this is less of a concern with regard to possible damage to the body part. This is due, on the one hand, to the fact that significantly fewer or smaller relative movements are possible between the spacer element (as part of the apron holder attached to the body part) and the body part than between the apron and the body part. In addition, it is possible to reduce the possibility of damage by means of a suitable geometry of the spacer element, while the geometry of the apron in the region of the dividing line is largely determined by its function as a cladding element.

According to a preferred embodiment, the apron has an outer section extending along the outer surface and a flange section extending therefrom, which is arranged adjacent to the body part and extends along a depth direction running transversely to the outer surface. The outer portion, which could also be referred to as the main portion or base portion of the skirt, extends along and forms part of the outer surface. That is to say, an outer side of the outer section normally has a color that corresponds to the intended vehicle color. On a side facing the body part, the flange section adjoins the outer section. The flange portion can normally be referred to as being angled with respect to the outer portion, that is, it extends at an angle to the outer portion or to the part of the outer portion adjacent to it. The flange section does not have to be straight, but can be bent and / or angled at least in sections. It is also possible for the flange section to have differently designed subsections along the dividing line. In any case, the flange section extends along a depth direction which runs transversely to the outer surface (and thus transversely to the direction of extension and to the direction of spacing). It can also be said that the flange portion extends inward from the outer surface. The function of the flange section can on the one hand be a structural stabilization of the apron, on the other hand it can serve as a contact surface for the at least one spacer element. Furthermore, various functional elements, which will be explained below, can be formed on the flange section.

The apron holder preferably has, as spacer elements, a plurality of finger elements spaced apart along the dividing line, each of which extends between the body part and the apron in the direction of the outer surface. The finger elements are spaced from one another along the dividing line, the distance between two adjacent finger elements preferably being greater than the width of a finger element, for example two to four times as large. The term “finger elements” is not to be interpreted restrictively in this context, although the shape of the individual finger element can normally be described as finger-shaped or finger-like. Each of the finger elements can extend from a main section or base section of the apron holder, which in turn is attached to the body part. It extends between the body part and the apron towards the outer surface. As a rule, however, the course of the individual finger element is not parallel to the depth direction. Also, the individual finger element does not generally have to be straight, but can be bent and / or angled in sections. An embodiment with individual finger elements that are spaced apart from one another can have various advantages over a spacer element that is continuous along the dividing line. On the one hand, this saves material and thus weight. Further each finger element can be deflected at least to a limited extent independently of the other finger elements, which can possibly be advantageous in order to compensate for manufacturing tolerances. In addition, it is possible to arrange other functional elements, which will be described below, between two finger elements.

At least one spacer element is preferably spaced apart from the outer surface in the depth direction. This can apply in particular to all spacer elements. This means that the respective spacer element does not extend between the body part and the apron as far as the outer surface, but rather recedes in the depth direction relative to the outer surface. This in turn has the consequence that the spacer element is not or is hardly visible from the outside. It also means that the minimum possible distance between the body part and the apron directly adjacent to the outer surface does not necessarily correspond to the extension of the spacer element. Rather, the skirt and the body part could have a smaller spacing directly on the outer surface where the spacer element is not interposed, while they could have a greater spacing where the spacer element is interposed. The spacer element can thus be made thicker and more stable, while at the same time there can be a narrow gap between the apron and the body part that is less perceptible to the outside.

At least one spacer element preferably rests on the one hand on the body part and on the other hand on the flange section. The respective spacer element forms a form fit in the spacing direction both with the body part and with the flange section. Thus, the flange section and the body part cannot move towards one another in the spacing direction - or at most with deformation of the spacer element. This can also prevent the outer surface section adjoining the flange section from moving towards the body part, as a result of which the provided gap could be reduced or even closed. Optionally, the spacer element can even be held under pretension between the body part and the flange section. The corresponding preload can result, for example, from an elastic deformation of the spacer element or of the flange section. Apart from the fact that a minimal gap width can be ensured much better by the embodiment shown here, a possible (albeit slight) relative movement of the spacer element with respect to the body part can also be prevented. Such a relative movement could lead to the spacer element hitting or rubbing against the body part, which in turn could damage the paint layer.

In order, on the one hand, to stabilize the respective finger element and, on the other hand, to ensure a material-saving and thus lightweight design of the apron holder, it is preferred that at least one finger element has a first rib section protruding in the spacing direction. The first rib section can, for example, protrude from a base section of the finger element. It goes without saying that the rib section is rib-like. Since it protrudes in the direction of the distance, it helps to stabilize the finger element against forces or pairs of forces which act in the direction of the distance. This would be, for example, forces that would move the apron towards the body part. Since the essential function of the finger element is to prevent such movement, the first rib section helps to ensure an intended minimum distance between the body part and the apron.

While the at least one spacer element serves to ensure a minimum distance between the apron and the body part, it is also advantageous to use structural measures to ensure that the distance does not exceed a specified maximum value or is limited upwards. According to a preferred embodiment, the apron holder has at least one support element which rests on the flange section on a side opposite the body part, as a result of which a distance between the body part and the apron is limited in the spacing direction. The respective support element is normally formed in one piece with the apron holder. It rests against the flange portion on a side that is opposite the body part along the spacing direction. So it can be said that it supports the flange portion. As a result, a form fit with the flange section and thus with the entire apron is thus formed, by means of which a movement of the apron directed away from the body part is prevented. According to one embodiment, the respective support element is arranged offset from each spacer element along the dividing line. So you could say that spacer elements and support elements alternate along the dividing line.

In order to ensure the necessary stability of the support element with the lowest possible material consumption or lower weight, it is preferred that at least one support element has a second rib section extending transversely to the direction of extension. The second rib section extends transversely to the dividing line or transversely to the direction of the dividing line and thus in one Plane defined by the distance direction and the depth direction. The second rib section can stabilize not only the support element as such, but also the apron holder as a whole.

The apron is preferably connected to the apron holder by means of a latching connection. In particular, at least one latching element of the apron holder can engage in a recess in the flange section, as a result of which a form fit is established between the apron and the apron holder in the depth direction. The locking element is normally formed in one piece with the apron holder. It can, for example, have a locking lug. The latching element engages in a recess or recess which is formed in the flange section. When the apron holder and the apron are joined together, the latching element and / or the flange section are elastically deflected until the latching element engages in the recess. This creates a form fit in the depth direction. The latching element is normally designed in such a way that it is not possible to pull the apron and apron holder apart without the latching element leading out of the recess. This function can be achieved in a manner known per se by means of a corresponding profile of the latching element which, for example, is beveled or ramp-shaped on one side and step-shaped on the other side. The respective latching element is preferably arranged offset along the dividing line to each spacer element and - if present - to each support element.

The connection between the body part and the apron is at least predominantly made by the apron holder. This connection can be supplemented at the end or in at least one end area of the dividing line. According to one possible embodiment, the body part and the apron have recesses aligned with one another at the end of the dividing line, through which a connecting means is passed, the apron having a projection formed on the edge of the recess, facing the body part, which has a rounded profile and rests on the body part. The connecting means, which can be designed in the form of a pin and can then also be referred to as a connecting pin or the like, is passed through a first recess on the apron side and through a second recess on the body part and thus establishes a form-fitting and possibly non-positive connection. For example, the connecting means can be designed as an expanding rivet. On the side of the apron, a projection is formed which is formed on the edge of the (first) recess. In particular, it can predominantly or completely surround the first recess and can be designed in an annular manner. If necessary, it can also be referred to as a bead. It has a rounded profile and rests on the body part. So there is direct contact between the apron and the body part. However, this contact is usually small and locally limited. This alone limits the possible effects of contact, i.e. possible damage to the paintwork and associated corrosion, to a minimum. Because the projection has a rounded profile, the probability of damage to the body part is further minimized. The recesses described here and the connection via the connecting means are normally provided at both end regions of the dividing line.

In the different figures, the same parts are always provided with the same reference numerals, which is why they are usually only described once.

1 shows a perspective view of a rear part of a body 1 of a car. In the simplified representation are a trunk lid 2 , a back door 3 as well as a recording area 4th recognizable for a rear light unit. On a side part 10 a rear apron closes at the rear 20th at. While the trunk lid 2 , the back door 3 as well as the side part 10 are made of painted sheet steel, the rear apron consists of 20th made of plastic. With regard to the surface appearance, it is to the side part 10 adapted, with which they share an exterior surface 6th the body 1 forms. One from the outside through the rear apron 20th concealed apron holder 30th , what a 1 is only indicated schematically, is on the side part 10 attached. The rear apron 20th turn is on the apron holder 30th attached. The side part 10 who have favourited the rear apron 20th as well as the apron holder 30th form parts of a body assembly 5 . Between the side part 10 and the rear apron 20th is along a dividing line 50 A gap 51 educated.

2 and 3 12 are perspective views of parts of the body assembly, respectively 5 , whereby for the sake of clarity in 2 only the side part 10 and the apron holder 30th are shown, while in 3 only the apron holder 30th as well as the rear apron 20th are shown. Here and in the following figures there is one direction in each case A. the dividing line 50 shown. In the embodiment shown here, the dividing line runs 50 mostly straight, which is why the direction of the course A. at most points of the dividing line 50 is aligned in the same way. At right angles to the direction of flow A. , but also parallel to the outer surface 6th , runs a distance direction B. . There is also a depth direction C. perpendicular to the outer surface 6th . 4th until 6th are different sectional views, in which the cutting plane is transverse to the direction of the course A. runs.

The plastic apron holder 30th is by rivets not shown in the figures on the side part 10 attached and thus stationary with respect to this. It has next to a main section 31 a series of finger elements 32 on, which serve as spacers in the spacing direction B. between the side part 10 and the rear apron 20th are intermediate. As in the sectional view in 4th is recognizable, each finger element lies 32 on the one hand on the side part 10 and on the other hand on a flange portion 22nd the rear apron 20th at. The flange section 22nd adjoins an outer section 21 at which part of the outer surface 6th forms. Each finger element extends 32 between the side part 10 and the flange portion 22nd towards the outer surface 6th towards, but not up to this, but is within the gap 51 hidden from the outside. In order to maintain the stability of the finger elements while using as little material as possible 32 to improve, each has one in the spacing direction B. protruding first rib section 33 on. The finger elements 32 make sure the gap 51 cannot close during normal driving of the car, but in the direction of the distance B. has a width of, for example, at least 0.1 mm or at least 0.3 mm. As in particular in 2 and 3 The individual finger elements are clearly recognizable 32 each spaced apart from one another, which among other things gives a certain flexibility to the individual finger elements 32 is guaranteed.

As in 2 as well as in the sectional view of 5 recognizable, shows the apron holder 30th furthermore several support elements 34 on, which are each on one in the spacing direction of the side part 10 opposite side on the flange section 22nd issue. The form fit thus produced prevents the rear apron from moving 20th in a noteworthy way from the side part 10 can move away. Thus, the width of the gap becomes 51 limited to a maximum value, which can be, for example, 0.5 mm. To the respective support element 34 To provide sufficient stability with the least possible use of material, it has a second flange section 35 and a third flange portion 36 on, which are each transverse to the direction of the course A. extend.

The connection between the rear apron 20th and the apron holder 30th is made in the present embodiment by a series of locking connections. One engages the apron holder 30th formed locking element 37 into one on the flange section 22nd trained recess 23 a. When assembling the body assembly 5 becomes the flange section 22nd in depth direction C. via the locking element 36 pushed away, due to the beveled shape of the locking element 37 an elastic deflection of the flange section 22nd and / or the locking element 37 in the distance direction B. takes place until the locking element 37 into the recess 32 slides in. This creates a form fit in the depth direction C. made of pulling off the rear apron 20th from the apron holder 30th prevented.

As in 2 easily recognizable are the finger elements 32 who have favourited Supporting Elements 34 as well as the locking elements 37 along the course direction A. each offset to one another.

In addition to the described connection of the rear apron 20th via the apron holder 30th on the side part 10 a further attachment is given, which is described below with reference to FIG 7th and 8th is described. At each end with respect to the dividing line 50 is on the rear apron 20th one from the outer section 21 angled connection section 24 formed which has a first through opening 25th having. In the assembled state, which is in 8th is shown, the first through opening is aligned 25th with a second through opening 11 on the side part 10 and an expanding rivet 40 is through both through holes 11 , 25th passed through, making the rear apron 20th and the side part 10 are positively connected to each other. Around the first through opening 25th around is an annular protrusion 26th trained the one Has rounded profile. This head start 26th in the assembled state lies on the surface of the side part 10 at. Even if there is direct contact between the rear apron here 20th and the side part 10 exists, the rounded profile and the small contact area minimize the risk of damage due to friction.
