Definitions

  • the present invention relates to a lid according to the preamble of claim 1, generic lid, as known from the prior art, serve to close an opening in a vehicle body, so for example an opening in a vehicle roof or for closing the opening of a side window, a rear window or a windshield.
  • Known blanket! for closing an opening in a vehicle body have a RandschDumung that forms sealing profiles and the reinforcing profiles, so-called “cover inner sheets”, receives to stiffen the lid.
  • the inner cover plates are partially or completely embedded in the RandumCumung.
  • Corresponding cover can be firmly inserted into the opening of the vehicle body, for example, glued or screwed to the body.
  • Lids, which can selectively strigen or release the opening of the vehicle body, which makes a displacement of the Deckenis relative to the opening in the vehicle body necessary, holding elements or brackets are further provided by softening the lid with a displacement mechanism which is arranged on the vehicle body , is connected.
  • Such brackets can also foamed into the RandumCumung, or be connected to the inner cover plate or the inner cover plate can form corresponding bracket.
  • known cover inner plates are made of steel or die-cast magnesium.
  • a disadvantage of known lids is the relatively high lid weight, which particularly influences the driving dynamics particularly when installing the lid in the roof area of a vehicle body above the center of gravity of the vehicle. Although some weight reduction is achieved with the use of magnesium diecasting coverings, such materials are very expensive.
  • a CFRP laminate element is arranged on the cover.
  • a CFRP laminate is a carbon fiber reinforced plastic composite material (colloquially often referred to only as "carbon") to understand in which carbon fiber, usually in multiple layers, are embedded as reinforcement in a plastic matrix.
  • the term "laminate” is intended to clarify that mats made of carbon fibers are joined together.
  • the use of CFRP laminate elements has the advantage that covers according to the invention for closing an opening in a vehicle body can be realized particularly easily on the one hand, and the manufacturing costs in comparison on the other hand to particularly lightweight metals such as magnesium are still relatively cheap.
  • the CFK laminate element is designed as a fastening element for fixed or displaceable connection of the lid to the vehicle body.
  • the CFRP laminate element may be formed as a reinforcing profile, in particular as a reinforcing frame for reinforcing the lid.
  • the lid has a transparent pane.
  • the CFRP laminate element is connected directly to the transparent pane.
  • the CFK laminate element may be glued to the disc of the lid.
  • the lid can preferably in addition to the CFRP laminate element still have a RandumCumung. This offers the advantage that the CFK laminate element and also other parts can be foamed onto the cover.
  • the RandumCumnung may have a comparison with RandumCumungen known lid reduced cross-section, since the CFRP laminate element already represents a substantial stiffening of the lid.
  • the CFRP laminate element can also be foamed onto the pane of the lid without forming a complete edge foam.
  • the CFRP laminate element is laminated to the disc of the lid. With the formation of the CFRP laminate element can thus be advantageously realized in the same process step, the connection with the lid.
  • the CFRP laminate element can form in the installed state of the lid a perpendicular to the vehicle interior aligned aperture so that no separate panel for privacy purposes must be grown. Similarly, the CFRP laminate member may also form a gutter.
  • the CFRP laminate element forms a projection for engaging behind an edge line of the opening of the vehicle body. Such engaging behind prevents lifting of the lid by wind forces.
  • the opening of the vehicle body is a vehicle roof opening, wherein the lid may be configured to tightly close the opening or to selectively open or close the opening.
  • a holding element can be embedded.
  • Glass lid; 3 shows an inventive Giesfestelement with a

  • Fig. 1 shows a lid 10 according to the invention for closing an opening in a vehicle body in a sectional view through the front edge (in the direction of travel) of the lid 10.
  • the lid 10 has a transparent plate 14, on which a CFK Laminatlement 12 is arranged.
  • the CFK Laminaieiement 12 can be glued to the disc 14 or laminated to the disc 14.
  • laminate is to be understood that during the formation of the CFK laminate element 12, that is, during the formation of the composite material, the CFK laminate element 12 is connected to the disc 14 at the same time. This can be achieved for example by appropriate carbon fiber mats are entered together with a liquid synthetic resin and the disc 14 in a corresponding shape, and after curing of the material, the lid 10, including integrally formed CFRP laminate element 12 is removed from this mold.
  • the CFRP laminate element 12 replaces a RandschJeumung example of a polyurethane foam (polyurethane).
  • the CFRP laminate element 12 can be designed as a complete frame around the edge regions of the cover 10. This brings in addition to a weight reduction and a stiffness advantage compared to a randumCumten glass lid, since the so-called hinge effect is bypassed. Under hinge effect is to be understood that at a RandumCumung, which surrounds the glass cover and a four-part inner cover plate having reinforcements along the Deckelvorder- and trailing edge, and brackets along the side edges, the reinforcements are tilted along their longitudinal axes under the influence of force.
  • the thickness of the disc (14) can also be reduced. Due to the higher rigidity of the CFRP laminate element 12 in comparison to edge foaming, it is also possible to dispense with an inner cover plate, which still leads to a considerable (albeit smaller) weight advantage compared to known covers with inner cover plates made of steel, compared to inner cover plates of magnesium die-casting. and in the latter case leads to a cost advantage in particular.
  • the laminate structure of the CFRP laminate element 12 can be designed to be load-compatible with the lids according to the invention, and thus additional weight can be saved.
  • a load-compatible design is to be understood that, in contrast to, for example, injection-molded materials with a fiber content in the CFRP laminate element 12, the fiber structure and fiber orientation can be selected so that the fibers are loaded in the Hauptbeiastungsraum essentially to train.
  • the CFRP laminate element 12 of FIG. 1 is provided with a projection 16 which serves to engage behind an edge line of an opening of a vehicle body or to reach under.
  • a projection 16 which serves to engage behind an edge line of an opening of a vehicle body or to reach under.
  • Fig. 2 shows a cross section through a side edge of the glass cover 10.
  • the cover of Fig. 2 may be the cover 10 of FIG.
  • a CFRP laminate element 12 is arranged on a transparent pane 10.
  • the CFRP laminate element 12 also serves to receive a retaining bracket 20 (retaining element) by means of which the cover 10 can be fixedly or displaceably connected to a vehicle body.
  • the holding member 20 may be made of a metal, for example, and connected to a corresponding fixed roof movement mechanism of the vehicle roof.
  • the CFRP laminate element 12 further forms an aperture 18, which is aligned substantially vertically downwards, ie in the direction of the vehicle interior.
  • the aperture 18 serves to shield the view from outside on areas to be covered. Such areas include, for example, the drive mechanism for the lid 10. Typical lengths for the aperture 18 are in the range of 1 to 5 cm.
  • a disc 14 for example, as in the other embodiments of a single-pane safety glass or laminated glass, not only provided with a CFK laminate element 12, but also in addition with a RandumCumung 26.
  • the RandumCumung 26 forms a gutter 22nd from, to collect water, which flows down from the top of the disc 14, sammein, and forward selectively.
  • the gully 22 may also be formed by the CFRP laminate element 12 itself.
  • the lid 10 of Fig. 3 is a glass fixed element with CFRP frame, which thus - in contrast to the covers 10 of FIGS. 1 and 2 - not displaced, but firmly closes an opening of a vehicle body.

  • the bond 24 reinforces the frictional connection between the CFRP laminate element 12 and the pane 14.
  • the bonding of the CFRP laminate element 12 can only take place via the edge foam 26 without additional bonding 24.
  • the connection of the CFRP laminate element 12 to the cover 10 of FIG. 3 represents a weight saving and a cost reduction, since the CFRP laminate element 12 replaces the usual one or more cover inner plates.
  • a cover 10 which can be fitted to the body or roof is likewise shown, in which, in contrast to the embodiment of FIG. 3, edge foaming has been completely dispensed with.
