Description

Motor vehicle door

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

Modern motor vehicle doors usually consist of a door frame (usually a multi-layer door panel construction) and on the inside of this door frame a door module for receiving elements such as speakers etc. Finally, a door trim is placed on the door panel or the door module for shapely conclusion to the interior of a motor vehicle.

Despite the lightweight construction requirements, it is important that the door trim meets aesthetically highest standards and in particular the assembly tolerances are kept down to the door panel down. Here, the installation should still be easy. It is also important that, for example, in the door trim provided door handle is as stable as possible despite the lightweight construction.

It is known to clip door panels perpendicularly to a door frame or module by means of latching elements. With inaccurate positioning of the elements to each other, the assembly can, however, make very expensive.

The present invention is therefore an object of the invention to provide a motor vehicle door, which is leichtbauend and yet stable and yet meets the highest requirements for tolerances with simple installation. This object is achieved by a motor vehicle door according to claim 1.

This is a motor vehicle door containing

• a door frame,

• a door module for holding function carriers such as speakers or the like, as well

• a door trim for the shapely completion of the door to the vehicle interior,

in which

• Door trim and door module corresponding locking elements for holding door trim and

Have door module in a predetermined arrangement to each other and

• Door module and door trim contain corresponding recesses, which upon engagement of the above-mentioned locking elements for receiving a with the door frame to be connected fastening member are arranged in alignment with each other.

It is important here that door trim and door module have mutually corresponding locking elements, which hold the door panel with respect to the door module. As a result, both are held in a predetermined arrangement to each other.

But then it is important that the door module and the door panel are aligned to the door frame as desired, to meet even the highest tolerance requirements. In addition, of course, a firm grip of the door panel or the door module on the door frame is important. For this purpose, door module and door trim on corresponding recesses, which are arranged in engagement with each other of the above-mentioned locking elements. In this position, this aligned opening serves to receive a fastening member, which fixes door module or door trim on the door frame. As a result, a high stability is achieved, in particular for to be arranged in the vicinity of the fastening member door handle lever, which are exposed to high mechanical stress.

In the following, the invention is summarized again with somewhat different words.

The aim of the invention is therefore to develop a "locator" (positioner / fastener) with which several functions are fulfilled simultaneously:

• reference the door trim to the door module,

• the complete "Inner Release Handle" area (Door handle inside) to connect with the inner door panel to keep the deformations on actuation low,

• to guarantee that the door trim can only be screwed when it is in the correct position.

A plastic sleeve is preferably formed on the door module, the door lining being referenced on this sleeve. The sleeve is thus a so-called "four-way locator" on the door module. The assembly takes place, for example, via a ramp arranged on the door module, the door trim is pushed over this ramp only when the locator hole with the collar of the

Sleeve (locator) matches, snaps the door panel in the correct position. Then the door panel can be bolted to the door module. The screw connection takes place, for example, directly into the door panel. Before the door panel in the right one

Position is snapped, it is preferably not possible to screw the screw through the door trim and through the sleeve in the inner panel. This type of self-discovery is also described as "Poke Yoke". This poke-yoke function could be achieved through tolerance tuning. If the door trim is still on the ramp, it is preferably not possible to bolt because the screw length is preferably too short to find the thread of the preferred weld nut in the sheet.

The following advantages can therefore be achieved with the invention:

• The inner-release handle area could be directly in the middle are bolted, therefore very high strength,

• the inner-release-handle-area could be referenced directly in the middle, smaller tolerances of the inner-release-handle-area are achieved;

• Poke-Yoke function, screwing is only possible if the four-way locator is completely in the correct position, saving costs and saving space,

• Realization of a safety function against incorrect screwing.

In the following, advantageous developments of the present invention will be described.

An advantageous development provides that the door frame can be constructed as a frame structure of support beams, which is provided with cover plates or cover plates. Alternatively, as is usual, it is also possible here to construct a multi-layered door panel construction as a structural bond with interior and exterior walls

Provide outer panel.

The door module can be made completely of plastic or entirely of metal, but hybrids are also possible. Preferably, the door module is designed substantially plate-shaped, wherein the door module covers the interior of the door frame partially or substantially over the entire surface. The advantage of a full-surface cover is the water-tightness, so that no moisture can penetrate into the door trim or the motor vehicle interior. The door panel preferably covers the entire surface of the door module and / or the door frame. The door panel can be made in one or more parts. The door panel may be formed of polymeric plastics or wood fiber molded materials. Perhaps a textile or leather lamination is given, preferably also a recess for a door handle module (inner release handle module) is given.

An advantageous development provides that the fastening member in the final assembly state is at least partially passed through the corresponding recesses and / or corresponding locking elements. The advantage here is that the Gesamtloca- tor can be built relatively small, since both the locking elements and the recesses (which receive the fastening member according to the invention aligned) are combined in a small space.

A further advantageous development provides that the corresponding recesses in the engaged and aligned state have a lower total depth of holing than in the unenacted state. This makes it possible that the attachment member only with a small total hole depth, for example, the door frame can engage. It is thus ensured that the actual fastening can only take place if the positioning is exactly correct. That is, the total hole depth in the latched and aligned state of the locking elements is so small that only by means of the fastening member door panel and door module on the door frame can be fixed. This fixation can for example be done by a nut, which on the inner door panel (preferably on the inside of the motor vehicle interior Ab-. facing side) is attached.

To ensure that the total blind depth in the locked and unencumbered state is different in each case, it can be provided that the corresponding recesses have mutually complementary regions which engage in one another in a form-fitting manner (but only in the locked state). A further advantageous development provides that the corresponding locking elements are designed as first and second latching element, wherein at least one of these latching element is an elastically engaging behind ele- ment, which engages in a corresponding opening. This is structurally easily accessible if the relevant parts of the door panel or the door module are made of plastic. It can be recessed in this case corresponding tongues or springs, which are resiliently mounted relative to the respective body. Here, the elastically engaging behind element itself a recess for

Including performing the fastening member or be arranged adjacent thereto.

A further advantageous development provides that the latching elements for engaging in one another are displaceable substantially in the direction perpendicular to the surface plane of the door module or in a direction of the surface plane of the door module. In this case, it is particularly appropriate to choose this direction of displacement in the direction of gravity (usually referred to as "negative Z direction" in motor vehicle construction). As a result, a latching is made by gravity itself, by a corresponding end stop also takes the Endpositionie- tion. The attachment member is preferably designed as a screw, rivet, nail or the like.

In addition to the attachment described above, at least one further "locator" is preferably provided. This can be, for example, a two-way locator arranged in the center of the area of the door module, which locator is mounted in the region of the armrest, since the power transmission is also high in this case.

It is particularly advantageous that the locking elements according to the invention have guides in their surroundings, so that a secure latching is possible. These may be lateral walls (the walls block a movement perpendicular to the guide direction), and a corresponding end stop should preferably be provided.

Further advantageous developments are specified in the remaining dependent claims.

The invention will now be described with reference to the following figures. Show it:

1 is a stylized plan view of a motor vehicle door according to the invention,

2a shows a perspective view of corresponding locking elements or recesses,

Fig. 2b shows a section according to sectional plane A of Fig. 2a and

3a-c details of a further embodiment of corresponding locking elements or meetings.

Fig. 1 shows a door frame 1 for a aufzusetzendes door module or for a door trim, which cover the interior of the door frame over the entire surface and liquid-tight.

It is a rear right side door of a four-door motor vehicle. The upper side of the door with the window frame there is not shown. In the following, the circled area marked with an arrow will be described in more detail (see FIGS. 2a and 2b). For the Fign. 1, 2 a and 2 b, the Cartesian coordinate system (X ₇ Y, Z) drawn in FIG. 1 is intended to serve.

Fig. 2a shows a door panel 3, which sits in the locked state on a door module 2. The section shown here in a circle corresponds essentially to that circled in FIG. 1; it is the periphery of a door handle 12.

Shown is a designed as an elastic element latching element 5a, which has a recess 6a. This is pushed onto the module by sliding in the negative Z direction, in which case said elastic element runs up as a first latch element 5b-executed ramp element until it snaps into the end position shown in FIG. 2a. In this end position complementary recesses 6a and 6b are engaged with each other. By the aligned opening of 6a and 6b, a fastening member 7 can be performed (see in particular Fig. 2b, to which reference is made below). In this way, a simple referencing of the door panel on the door module and the area around the door handle around Can be screwed directly in the middle with the door module.

Fig. 2b shows a cross section according to sectional plane A. To see here is a part of a door frame 1. Specifically, this is the inner panel of a executed as a structural composite with inner and outer panels door frame. This door frame is preferably made of textured sheet metal. The door module 2 covers the opening of this door frame substantially over the entire surface. The door module here is made of plastic (polypropylene, with long glass fiber surcharge). A door panel 3 covers the door module 2 substantially over the entire surface. In the region of the fastening member 7, a door handle module 8 is also shown, which can be subsequently fitted into the panel.

In Fig. 2b the latched final state is shown. Here, a first latching element 5a is shown, which belongs to the door panel 3. By sliding in the direction of the arrow (ie, negative Z direction), this element is pushed over the second latching element 5b designed as a ramp and finally snaps into the final state shown in FIG. 2b. Here, the first recess 6a concentrically surrounds the second recess 6b. The first recess 6a is shown here as a circular hole in the door panel. The second recess 6b is also a circular hole, which is given in the region of a collar 60 of the door module, wherein the outside of this collar 60 engages positively in the inner surface of the first recess 6a. The first recess 6a is in this case part of the first latching element 5a. In the state shown in Fig. 2b also the fastening member 7 is screwed. overall This is countered on the back of the door inner panel by a mother welded there. It is exploited here that the corresponding recesses 6a and 6b have a low total blind depth t in the locked and aligned state (FIG. 2b) than in the unenacted state.

Because of the total hole depth t, reference is made to FIG. 2b. In the unlocked state, the underside of the door trim shown in FIG. 2b is arranged, for example, on the highest step of the second latching element 5b, or on the collar 60 of the second recess 6b. As a result, the total hole depth is significantly larger. As a result, the fastening member 7 with its thread can not engage in the lock nut. As a result, it is ensured that an attachment in the non-optimal state is avoided.

It is thus shown that the corresponding locking elements are designed as first (5a) and second (5b) locking element, wherein at least one of these locking elements is an elastically engaging behind element (present 5a), which in a corresponding opening (for example, the collar 60 to the second recess 6b) engages.

Shown is thus a motor vehicle door, comprising a door frame 1, a door module for receiving function carriers such as speakers, power window drives, control electronics, speakers or the like, and a door trim 3 for shapely completion of the door to the vehicle interior, said door trim 3 and door module 2 corresponding locking elements ( 5a, 5b) for holding the door trim 3 and the door module 2 in a predetermined arrangement. have each other. The door module 2 and the door panel 3 have corresponding recesses 6a, 6b, which are arranged in alignment with one another when the above-mentioned latching elements 5a, 5b engage, so that they form a passage opening. This passage opening serves to receive a fastening member 7, whereby door module and door trim can be connected to the door frame 1.

FIGS. 3 shows details of another embodiment. In Fig. 3a, a door module 2 is shown. Particular mention should be made here of a second connection point 9 which fixes the door trim in the area of the arm rest support, in positive or negative Z direction.

In Fig. 3b of the door module, the portion of the door module is shown, which has a recess for performing a fastening member 7. Here, the guides 10 are shown in plan view substantially "U" -shaped. Here, the left and the right leg of the U serve as walls which guide a corresponding portion of the door panel in the negative Z direction. The underside of the "U" in this case forms an end stop 11. As a second locking elements are protruding ramps or lugs 5b ¹ , which are arranged parallel to each other shown. In the area of these noses it should also be noted that the upper legs of the "U" are inclined slightly outwards, this serves as a "leading incline". Emphasize is the recess 6b ¹ , which has a collar 60 ', which projects beyond the adjacent surface of the module. The outer surface of this collar 60 'is here designed so that the inner surface of the first recess 6a ¹ positively engages therein. In Fig. 3c, a first locking element 5a ^{1 is} shown, which is designed substantially pot-shaped, and is part of the door trim. This pot is about the second locking elements 5b ¹ of position I in

Arrow direction pushed and locks in the position II shown in Fig. 3c, so that the edge regions of the recesses 6a 'and 6b ¹ intermesh positively, so as to give a minimum Gesamtlochtie- fe here. After this, a fastening element 7, for example a screw, can then be passed through and screwed tight to a door frame for attachment.
