Description

The The invention relates to a component and a method for fastening a component.

at the attachment of body parts to a vehicle this fixed at certain predetermined positions. For example a mudguard at certain mounting points with the vehicle screwed.

are the body parts attached to the vehicle, z. B. in the context a cathodic dip coating (KTL) a corrosion protection in an on-line process with drying temperatures of up to approx. 200 ° C applied. In a so-called. In-line method is the component is mounted on the vehicle after the KTL dryer. Lacquer drying temperatures of up to approx. 140 ° C prevail here.

Increasingly be used as body parts and plastics, the one compared to steel or aluminum significantly larger Have thermal expansion coefficient. When heated in a paint dryer expands a plastic body part accordingly stronger. A rigid attachment of the plastic parts causes them to deform irreversibly, eg. B. bulge, resulting in terms of aesthetic design of the vehicle is unacceptable.

A such expansion finds - albeit in reduced Scope - even in the usual use of a motor vehicle instead of. So can in certain areas to certain Seasons body panels temperatures up to about 85 ° C temperatures, whereas in a wintry environment temperatures are also high less than -35 ° C without visible deformation the body parts must be possible.

Disclosed in this context DE 699 03 875 T2 a fastening device ("sliding fastening device") which allows a sliding movement of the body part with respect to a structural part of the motor vehicle.

in this connection it is disadvantageous that the Gleitbefestigungsvorrichtung consuming and in particular must be placed in advance in the context of assembly.

The The object of the invention is the disadvantages mentioned above and in particular an efficient and improved way specify the positioning and assembly of a component, the Component advantageous even at high temperatures an expansion along a glide path can compensate.

These Task is performed according to the characteristics of the independent Claims solved. Further developments of the invention also result from the dependent claims.

hereby the advantages of the sliding element are realized, by means of which the Component is movably fixable along the longitudinal groove is such, that z. B. Temperature changes and thereby resulting changes of the component along the glide path can be compensated. This effectively prevents that the part due to size changes z. B. as a result of temperature fluctuations, shrinkage processes or changing moisture content forms bumps or waves.

The Receiving element is particularly suitable for positioning and for receiving the sliding element. Thus, advantageously, the sliding element with the component are connected captively, z. B. based on a detent or snap mechanism. As a result, also the position of the sliding element within the longitudinal groove determined. This is particularly beneficial in an automated assembly of the component, for. B. screwing with a carrier: through the pre-positioned sliding element can at substantially the same repeated position the connection of the component with the carrier (via the sliding element) respectively. In particular, thus can be a complex positioning of the robot, z. For a search for the opening for screwing the component to the carrier, omitted.

A Further development is that the predetermined separation point a predetermined breaking point is.

It is an embodiment that the component one of example a structural part of a motor vehicle significantly different having thermal (linear) expansion coefficients.

1 shows a plastic part 101 with a longitudinal groove 104 , where the plastic part 101 integral with a receiving element 103 (in 1 shown as webs) for positioning a sliding element 102 is executed. The sliding element is preferably made of metal or alternatively of plastic. In 1 is the sliding element 102 thus by means of a snap connection via the receiving element 103 with the plastic part 101 captive connected. The sliding element 102 preferably has an opening which is suitable for mounting the plastic part on a support. For example, as part of an automated assembly, a robot can selectively control the opening and a detachable or non-detachable connection of the plastic part 101 with the carrier. This is the captive connection between the plastic part 101 and the slider 102 by engagement of the sliding element 102 in the longitudinal groove 104 severed at a predetermined breaking point.

Exemplary is the plastic part 101 a body part of a motor vehicle, for. As a fender, a bumper or a roof. The figures show in particular with reference to the plastic part 101 a section for such a body part for mounting on the carrier, z. On or on the body (eg on the chassis) of a motor vehicle. In particular, the body part of the vehicle can have several such longitudinal grooves 104 exhibit.

2 shows a perspective section along the longitudinal groove 104 (please refer 1 ), wherein the sliding element 102 with the receiving element 103 connected captively in the form of two webs, in particular via latching hooks 105 is locked. In 2 is also shown that in the captive connection of the sliding element 102 with the plastic part 101 the sliding element 102 preferably not completely in the longitudinal groove 104 intervenes. Only with said assembly of the plastic part 101 on the carrier becomes the sliding element 102 further pressed into the longitudinal groove, wherein the predetermined breaking points between the receiving element 103 and the plastic part 102 be severed. This connection is (without fastening means, eg screw, for mounting the plastic part 102 on the carrier) in 3 shown. Here are the webs of the receiving element 103 separated, the sliding element 102 engages as far as possible in the longitudinal groove 104 one.

4 shows the slider 102 with snap hook 105 for engagement with the receiving element 103 , According to shows 5 an isometric view of the longitudinal groove 104 the plastic part 101 comprising the receiving element 103 , Thus, the sliding element 102 according to 4 with the webs of the receiving element according to 5 be locked. In this case, the slider is 102 with the plastic part 102 captive connected. This poses as described, one step before mounting the plastic part 101 on the carrier

As shown in FIG 2 shows 6 a section through the longitudinal groove 104 , The sliding element 102 is captive with the plastic part 101 connected by the latching hook 105 with the jetties 103 are locked.

7A shows an arrangement of the plastic part 101 and the slider 102 that over the receiving element 103 captive with the plastic part 101 connected is. A screw 106 is over a cover 107 through the opening of the receiving element 103 guided and the plastic part 101 is with a carrier (not shown, below the sliding member 102 ) (see 7B ). This is the sliding element 102 in the longitudinal groove 104 the plastic part 101 introduced and the at least one predetermined breaking point is severed, which in the case shown a separation of the webs of the receiving element 103 equivalent. The sliding element 102 is now firmly connected to the carrier, the plastic part 101 can on the slider, z. B. with temperature fluctuations, with respect to the carrier and thus unwanted deformations of the plastic part 101 prevent.

8th shows an isometric view after transection of the at least one predetermined breaking point accordingly 7 from the perspective of the wearer.

It should be noted that although the receiving element 103 is shown by way of example in the form of two webs, a variety of other forms are possible. For example, the receiving element 103 have a web or more than two webs, in particular, the webs need not be perpendicular to the longitudinal groove 104 be executed. Furthermore, it is possible that the receiving element comprises a frame with a square or round opening. Depending on the shape of the receiving element, the sliding element is preferably designed as a receiving counter element, so that it can be positioned captively in the longitudinal groove with the receiving element.
