Definitions

  • the invention relates to a motor vehicle door according to the Oberbe ⁇ handle of claim 1.
  • motor vehicle doors in modern cars are often composed of different modules.
  • the motor vehicle door frequently comprises an outer module which has a frame, an outer panel and side impact protection strips, as well as an inner module which essentially serves for fastening attachment parts and door coverings.
  • the inner module has a plastic housing onto which a door inner lining is subsequently applied by lamination. Different units and components, such as loudspeakers, are also fastened to this plastic housing.
  • An additional hybrid component which is constructed from plastic and metal, is subsequently screwed to this plastic housing. Starting from a door assembly, this hybrid component is viewed from the outside to the inside in about the middle, positioned within a disk plane.
  • the actual plastic housing, to which the hybrid component is screwed assumes no supporting properties. This leads to the fact that the rigidity of this inner module or the entire vehicle door can be improved.
  • the assembly work for the composite interior module is comparatively high. Furthermore, the installation space in the door is not optimally utilized by the hybrid component lying in the middle, which has a negative effect on the interior width, among other things.
  • the object of the invention is accordingly to improve the stiffness of the door in comparison to the prior art, to reduce the assembly effort and to ensure a better utilization of the available construction space.
  • the motor vehicle door according to claim 1 comprises an outer and an inner module, wherein the inner module has a Mosinnen ⁇ lining, which is applied to a supporting surface of the inner module.
  • any kind of Ka ⁇ is understood sch michen, for example, leather, fabric or plastic covers, which are optionally applied to a zwi ⁇ rule-stored foam, and other Anbau ⁇ parts, such as handles or storage compartments.
  • These door linings serve for the decorative design of the inner space and are applied to a supporting surface of the inner module by appropriate joining methods.
  • the invention is characterized in that the inner module has a support structure which forms a reinforcing frame. includes. This reinforcing frame is joined to a plastic component carrier to form a hybrid component.
  • the hybrid component is designed in such a way that on the one hand it improves the rigidity of the inner module and thus of the entire door and at the same time forms the load-bearing surface of the door lining.
  • the reinforcing frame is often designed in the form of a metallic frame, wherein metals such as steel, aluminum or magnesium are used, which can be produced by conventional Umform ⁇ technology and casting techniques. However, it is also expedient to provide the reinforcing frame by means of an insert in the form of a fiber-reinforced plastic.
  • the support structure of the inner module is thus configured by an integrated hybrid component.
  • the lack of a load-bearing hybrid component in the center of the door thus significantly improves the space utilization in the vehicle door, increases the rigidity and facilitates the mounting of add-on parts, since a high degree of integration of add-on parts is made possible for the hybrid component itself.
  • the support structure of the inner module may be configured such that it additionally comprises a window sill and / or a door bottom as well as a rear door front side.
  • the outer module can be made correspondingly narrower, which in turn means that the Trennebe ⁇ ne between the inner and outer module can be moved further towards the vehicle outside, which in turn to an increase the elbow room in the passenger compartment leads.
  • the rear door front side can be configured on the inner module in such a way that a door lock is arranged on it.
  • the arrangement of the door lock on the separately vororm ⁇ tierbaren, inner module also improves the total daily assembly costs during assembly of the motor vehicle door.
  • a door seal extends along a joining surface, in which the outer and the inner module are joined together.
  • this also serves for a better sealing of the joining surface and, in addition, can also serve to cover screwing points which run along the joining surface through the door seal, which offers optical advantages.
  • the support structure of the inner module which is designed in the form of the genann ⁇ th hybrid component, may be geometrically shaped in such a way that housings for corresponding Anbau ⁇ parts on the inner module, for example, are formed for aggregates in the desired manner.
  • the plastic base support which forms part of the hybrid component, advantageously have fastening means, which are already integrated into the plastic base support by the manufacturing method. These fasteners also serve to fasten attachments in units.
  • a drive unit of a power window can be mounted in the outer module of the power door. This also leads to a better utilization of the available installation space.
  • the drive unit for the power window between a window pane plane and a Door exterior planking is appropriate. This area of the motor vehicle door is otherwise unused.
  • a front door front side on the outer module, which is staggered stepwise in its cross section.
  • This stepped region of the Schostirn ⁇ side can limit a hollow cross-section together with a front end portion of the inne ren module.
  • the rigidity of the motor vehicle door especially in the high-loaded front door area, is increased again. This increase occurs, in particular, even when the hybrid component of the inner module is designed in the region of the hollow cross-sectional boundary in the form of a metal or the metallic frame, and thus the hollow cross-section is delimited circumferentially by a metal.
  • FIG. 3 shows the support structure or the hybrid component of the inner module with a graphic distinction between reinforcing frame and plastic base support
