Description

The invention relates to a motor vehicle door according to claim 1.

Such a motor vehicle door comprises an external assembly, one outer door skin has and an outer design surface of the Motor vehicle door forms as well as an assembly carrier, on the side of the outer assembly assigned to a vehicle interior arranged and connected to this as well as electrical and / or electrical functional components of the motor vehicle door carries.

The outer assembly of the motor vehicle door therefore embossed especially that from outside of the motor vehicle visible appearance and is with the associated motor vehicle to paint in a uniform color. The one on the inside the outer assembly arranged subframe serves in particular to accommodate the mechanical and electrical Functional components provided on a motor vehicle door are, e.g. a lock assembly, a window regulator, one Loudspeaker, a side airbag module, etc. Particularly advantageous is the arrangement of all such electrical or mechanical functional components on the assembly carrier, so that these can be completely pre-assembled with the subframe and testable door module summarize that later is connected to the external assembly in the pre-assembled state.

According to the invention, the outer assembly the motor vehicle door in the area of its outer edge gain regions so that it has sufficient inherent rigidity and can be handled as a separate door element that is independent of the subframe only in a final one Assembly step with the subframe to produce the complete vehicle door is connected. In particular, lets the outer skin of the door such an outer assembly due to their inherent rigidity regardless of the assembly with the subframe paint. this makes possible a common painting of the outer assembly of the vehicle door together with the rest of the body the associated Motor vehicle in a uniform painting process, so that a uniform coloring of the vehicle body on the one hand and the outer skin the associated vehicle doors on the other hand, guaranteed is. Can at the same time the other components of the motor vehicle door completely independent of the outer assembly can be manufactured and assembled at any location, whereby a from the subframe and the door module formed on it pre-assembled functional components.

The subframe with the pre-assembled on it door components is transported to the assembly site of the motor vehicle, where the assembly carrier and the outer assembly the vehicle door be connected to each other. The vehicle door thus completed can then in this for this provided motor vehicle be installed.

The reinforcement areas of the outer assembly preferably stand inwards, i.e. towards the hereby unit carrier to be connected, from the external assembly off and can along of the entire outer edge the outer assembly circulate.

The reinforcement areas can by separate reinforcement elements are formed, which are attached to the inside of the outer assembly. Therefor reinforcement plates are suitable, for example, also in shape a completely encircling reinforcement frame. In the case of an outer assembly consisting of plastic or metal, in particular sheet metal can the reinforcement areas too directly on the outer skin of the door molded, e.g. in the case of metal, by deep drawing or stamping.

In addition, can be on the outer assembly or the subframe a cross member to be arranged across the inside of the outer door skin or the subframe extends and the stiffening of the vehicle door with regard to a side crash serves.

The subframe can have a frame structure with an integrated window frame. This frame structure surrounds a large support plate the subframe, to accommodate the electrical and mechanical functional components the vehicle door serves and educates about it also a window opening.

The assembly carrier is preferably of such a large area that that it extends to the side edges of the motor vehicle door. This differentiates the subframe from the usual ones Door module carriers that on a recess in the inner door panel a motor vehicle door be placed and accordingly completely within the outer edges of the Motor vehicle door lie and accordingly extend up to these.

The subframe can also in the area of its outer edge gain regions which preferably face outwards, i.e. towards the Exterior assembly, protrude from this and which are either integrally formed on this or through separate reinforcement elements can be formed. The reinforcement areas of the subframe can at the same time form part of a frame structure of the subframe.

Furthermore, the outer assembly of the vehicle door and the Unit carrier about their gain regions abut each other, the reinforcement areas continue to attachment points Connection of external assembly and subframe exhibit.

The assembly carrier can be independent of the external assembly and independent of the rest of the body of the associated motor vehicle be produced in a separate location and with a color that is independent of the color of the motor vehicle. This is because the exterior view of the motor vehicle door designed according to the invention is determined by the exterior assembly, which is accordingly to be painted in a uniform color together with the other areas of the vehicle body.

In a preferred embodiment of the invention along the interface of the outer assembly and subframe Seal that covers this interface and in particular can be the main seal of the vehicle door through which the vehicle door is in contact with the vehicle body when closed. Furthermore can this seal also provide a tight connection between the subframe and exterior assembly to ensure.

In addition to the interface between assembly carrier and outer assembly the seal can also cover the fasteners over which the exterior assembly with the subframe is connected, and possibly elements of a reference point system, that serves to align the individual components of the vehicle door. This ensures that the interface, the fasteners as well as the elements of the reference point system from the vehicle interior here, so for an occupant sitting in the vehicle, not when opening the vehicle door are visible.

According to one embodiment the invention is the seal before assembly of subframe and exterior assembly on the subframe preassembled. Here, the seal on the subframe can initially in a first position (pre-assembly position) can be determined in that does not yet cover the attachment points, that of the attachment the outer assembly on the subframe serve. Only after connecting the outer assembly and subframe the seal is then moved to a second position (functional position), in which it covers the attachment points. This simplifies it assembly when connecting the external assembly and subframe. It is also possible that the seal at the mounting location of the vehicle door from its merely as a transport position serving first position and after connecting assembly carrier and outer assembly again in its second position serving as a functional position is applied and fixed. According to another variant, the Seal on the subframe already pre-assembled in its functional position; it can be however for connecting the external assembly and subframe move or fold over in such a way that the necessary Fastening points are released. This can in particular the elasticity of the Seal are used.

According to another embodiment the invention, the seal is only after the connection of subframe and exterior assembly applied and fixed.

To attach the seal on Subframe in particular in its edge area, positive locking areas are provided (molded), which is a positive fastening of the seal on the subframe enable.

Furthermore, a Door lining provided (pre-assembled) that the subframe in the field of view covering the interior of the vehicle. As a result, they are not in the body color painted parts of the door, namely those to the vehicle interior facing areas of the subframe, unless they are covered are already covered by the seal.

On the subframe or alternatively on the outer assembly, especially at their reinforcement areas, can about that In addition, the hinges of the vehicle door must be fixed. If the Hinges on the outer assembly are provided, then the outer assembly can be shared Painting with the vehicle body over the hinges with this be connected and also during of the later Assembly with the subframe remain on the body.

Other features and advantages of Invention will be described in the following of an embodiment become clear from the figures.

Show it:

1a - 1d four different perspective views of a motor vehicle door consisting of an assembly carrier and an external assembly connected to it;

2a the subframe from the 1a to 1d ;

2 B the outer assembly from the 1a to 1d ;

3 a vehicle door according to the 1a to 1d in exploded view;

4a a schematic representation of the connection area between the outer assembly and subframe;

4b a more detailed representation of the connection area according to 4a ,

In the 1a to 1d a vehicle door is shown, which consists of a in 2a subframe shown separately 1 and one in 2 B outer assembly shown separately 2 consists.

The subframe 1 is formed by a support plate made of metal (sheet metal) 10 , at the lower, and in the vehicle longitudinal direction x front and rear edge area in each case to the outside, ie in the direction of the outer assembly 2 protruding reinforcement areas 15 are formed by stamping or deep drawing. These reinforcement areas 15 also form the support plate 10 U-shaped frame. In addition, the support plate 10 a reinforced parapet area 17 on. On the U-shaped reinforcement and frame area 15 of the subframe 1 a window frame closes upwards 16 which defines and encloses an opening for a window pane in the usual way.

The subframe 1 also points between the parapet 17 and window frames 16 in the usual way a mirror triangle 18 on. Furthermore, is on the peripheral frame parts 15 . 16 of the subframe 1 a seal 19 pre-assembled, which on the one hand serves as the main door seal, via which the vehicle door bears against the door body when closed. On the other hand, the seal serves 19 also for sealing the connection between subframe 1 and outer assembly 2 , Furthermore, the seal can also serve as a damping means with regard to external noise (sound).

The outer assembly 2 is formed by external planking 20 (Outer door skin), in the area of its outer edge all around with a reinforcing plate in the form of a reinforcing frame 21 . 22 . 23 . 24 is provided. Each of the four areas 21 . 22 . 23 . 24 of the reinforcement plate runs along an edge area of the outer skin 10 and is always facing inwards, ie towards the subframe 1 , from the outer door skin 2 from. Because of the reinforcement areas 21 to 24 has the outer assembly 2 sufficient inherent rigidity so that it is independent of the subframe 1 can be handled and painted.

Between the two lateral (front) reinforcement areas viewed in the vehicle longitudinal direction x 22 . 24 the outer assembly 2 extends a cross member 25 (Side impact beam), the stiffening of the outer assembly 2 and thus the vehicle door as a whole serves with regard to a side crash. The elongated cross member 25 is with its front and rear ends on one of the two end reinforcement areas 22 . 24 attached. In addition, are at the front end reinforcement area x in the vehicle longitudinal direction 22 two hinges 28 . 29 arranged, via which the vehicle door can be hingedly connected to a vehicle body.

Because of the inherent rigidity of the outer assembly 2 the vehicle door can be made independently of the subframe, with hinges 28 . 29 provided and on their outer planking 20 be painted. The painting is preferably carried out together with the other areas of the vehicle body in a uniform painting process, so that deviations in the color of the vehicle door on the one hand and the other areas of the vehicle body on the other are excluded. The production, assembly and painting steps mentioned can be carried out at the manufacturer of the corresponding motor vehicle.

Regardless, in a separate location, e.g. B. at a supplier of the corresponding vehicle manufacturer, the subframe 1 to get prepared. On the carrier plate 10 of the subframe 1 For this purpose, the electrical and mechanical functional components provided on the motor vehicle door are preassembled, which are described below 3 will be described in more detail. In addition, on the subframe 1 along its frame parts 15 . 16 a door seal 19 applied, which ensures, among other things, as a door main seal for tight sealing of the vehicle door on the vehicle body. The color of the subframe 1 can be regardless of the color of the outer assembly 2 selected and in particular does not have to match the color in which the body of the corresponding motor vehicle is painted. Rather, a neutral color is suitable for this, e.g. B. white, gray or black, or the interior color of the corresponding motor vehicle.

Based on the exploded view in 3 is the structure of the in the 1a to 1b illustrated motor vehicle door again clarified. The subframe 1 with a carrier plate 15 and frame areas 15 . 16 which the one hand the carrier plate 10 comprise and on the other hand define a window frame, is used to hold an electric window regulator 3 , a speaker 4 , a plurality of harnesses 5 and another door assembly 6 , The mechanical elements of the window regulator 3 , namely guide rails 30 , a Bowden cable 31 , a gear assembly 32 and by means of the Bowden cable 31 along the guide rails 30 guided carriers 35 are on the wet room side of the carrier plate 10 , ie on their the outer assembly 2 facing surface arranged. On the two drivers 35 the window regulator 3 a window pane F can be fastened, which for this purpose has two fastening areas B on its underside, each with a fastening opening.

On the drying room side, ie on the side facing the vehicle interior, of the subframe 1 are on the carrier plate 10 the drive motor 33 of the window regulator, the loudspeaker unit 4 who have favourited Harnesses 5 as well as the further assembly 6 assembled. As further assemblies on the carrier plate 10 can be preassembled, for example, a lock assembly, a side airbag module, an armrest, etc.

The aforementioned functional elements 3 . 4 . 5 . 6 the vehicle door will be on the support plate 10 pre-assembled before this with the outer assembly 2 is connected. This also applies to the window pane F, which has its fastening areas B and the drivers 35 with the window regulator 3 communicates. The subframe 1 , the other functional elements 3 to 6 and the window pane F thus form a complete door module in the preassembled state, which includes all door elements except the outer skin of the door.

The outer door skin 20 is in a separate external assembly 2 the vehicle door integrated due to their stiffening areas 21 to 24 has sufficient inherent rigidity to be independent from the subframe 1 to be handled and especially painted.

The assembly of the subframe 1 and the functional components pre-assembled on it 3 to 6 , F with the outer assembly 2 forms the final assembly step in the manufacture of the vehicle door as a whole.

4a shows schematically the interface S between subframe 1 and the outer assembly 2 with outer door skin 20 forms. The outer door skin 20 points to their edge 20a an inwardly folded material area, the attachment of a reinforcement area 24 serves. The angled reinforcement area 24 can be between the outer door skin 20 and their folded edge area 20a be pinched. Additionally or alternatively, a connection can be made by gluing, welding, screwing, riveting or other suitable fastening methods. The other reinforcement areas 21 . 22 . 23 the outer assembly 2 (see 2 B ) are in a corresponding manner with the external flanking 20 connected and ensure the special inherent rigidity of the external assembly 2 ,

The reinforcement areas also form part of the door inner panel of the motor vehicle door, through the support plate 10 of the subframe 1 is completed. The carrier plate 10 of the subframe 1 points outwards at its lateral edge region, ie towards the outer assembly 2 protruding reinforcement areas 15 on, the frame areas (frame parts) of the subframe 1 form.

The reinforcement area 15 of the subframe 1 as well as the gain area 24 the outer assembly 2 are angled in such a way that they form abutting surfaces over which the outer module 2 with the subframe 1 connected is. The corresponding interface is through the seal 19 covered, which also serves as the main door seal.

Further details of a specific design of the interface S between subframe 1 and outer assembly 2 are 4b removable. After that are the reinforcement area 15 of the subframe 1 as well as the gain area 24 the outer assembly 2 using fasteners 100 connected in the form of screws, each with mounting holes in the two reinforcement areas 15 . 24 succeed.

Furthermore, the reinforcement area 15 of the subframe 1 a fastening section at its free end 15a on which the seal 19 is form-fitting, so that it can be attached to the subframe 1 can be pre-assembled. After connecting subframe 1 and outer assembly 2 becomes the seal 19 also with a section 19a between the attachment areas 15 . 24 trapped. On the one hand, this is the connection between the subframe 1 and outer assembly 2 sealed and also the seal 19 kept safe. Based on 4a and 4b it can also be seen that the seal 19 the interface S between the subframe 1 and outer assembly 2 covered.

The exemplary embodiment of a door assembly described above consisting of an assembly carrier 1 and an outer assembly 2 can be modified in many ways.

The two-part construction can also be selected for frameless vehicle doors; in this case the subframe points 1 no window frame.

The reinforcement areas 15 of the subframe 1 on the one hand and the reinforcement areas 21 to 24 the outer assembly, on the other hand, can consist of different materials and, independently of this, also have different material thicknesses. Usually with the subframe 1 a higher rigidity is required than for the outer assembly 2 so that their gain areas 21 to 24 can be formed with a lower material thickness and / or from a lighter, less stable material.

The reinforcement areas 15 . 22 to 24 of the subframe 1 and the outer assembly 2 can also facilitate the positioning of the two assemblies 1 . 2 have guide areas to one another, so that the assembly is simplified. Furthermore, the reinforcement areas can also serve as pane guides for a lowerable window pane and the section of the assembly carrier serving as a window frame can have a glass channel.

The seal at the interface of subframe 1 and outer assembly 2 is arranged, can also be used to connect the outer assembly 2 with the subframe 1 serve; For this purpose, corresponding fastening means are integrated into the seal, which when the seal is pressed into the area of the interface S between the assembly carrier 1 and outer assembly 2 take effect, e.g. B. by in appropriate mounting points on the subframe 1 and / or the outer assembly 2 intervene and thereby create a positive and / or non-positive connection. On the other hand, fasteners that are separate from the seal can also be used before the assembly carrier is assembled 1 and outer assembly 2 on one of these two parts, especially on the subframe 1 , be pre-assembled. It is then not necessary at the assembly site where the subframe is located 1 and the outer assembly 2 are interconnected to provide separate fasteners.

The door lining with which the subframe 1 towards the vehicle interior can be covered in the area of the interface of the subframe 1 and external assembly 2 be attached, being the reinforcement areas 15 . 21 to 24 at de at least partially encompasses the edge. This creates an undercut, which enables simple and secure attachment of the door interior trim. The interior door trim can be fixed to the edge of the reinforcement areas in a form-fitting, force-locking or using additional fastening means.
