Description

The invention relates to a modular cassette for installation in a vehicle door, a vehicle door with such a modular cassette, and a method for manufacturing a vehicle door.

Modern vehicle doors can incorporate a variety of functional modules. For example, they can include a lock, a window, speakers, and other components, all attached to a supporting structure within the door. However, the effort required to mount all these functional modules to this supporting structure can be considerable.

To reduce the assembly effort on the supporting structure, a modular carrier can be provided. This can be pre-equipped with some of the functional modules and then attached to the supporting structure of the vehicle door as a pre-assembled unit.

The WO 2016/177738 A1 describes a door module for a motor vehicle door, which can also be called a module cassette, with a module carrier which is formed to a substantial extent by organosheet, with a connection area of the module carrier which is surrounded by a projection of the organosheet, with a window lifter drive of a motor vehicle window lifter arranged on the connection area and with a flexible traction element extending from and coupled to the window lifter drive, which extends along the module carrier.

The task is to specify an improved module cassette for a vehicle door, which allows the assembly of the vehicle door to be further simplified.

This problem is solved by an object having the features of claim 1.

A modular cassette for installation in a vehicle door comprises a carrier and at least one functional module. The carrier has a wet side (e.g., splash-proof and/or exposed to splash water when installed in the vehicle), which faces an outside of the vehicle door when installed, and a dry side opposite the wet side, which faces an inside of the vehicle door when installed. Furthermore, the carrier has several mounting points for attaching it to the door frame of the vehicle door. The at least one functional module is mounted on the carrier. A sealing surface is provided on the dry side of the carrier, designed to seal the dry side from the wet side on the door frame.

This is based on the understanding that some functional modules are at least partially located on the wet side. Currently, these modules are threaded through an opening in the inner door panel of the door frame for assembly. However, this can be time-consuming and limit the possible dimensions of the functional modules. The described design allows the module cassette to be mounted on the door frame from the wet side, rather than the dry side. This is done before other steps in the assembly of the vehicle door, such as before the outer door skin is installed, i.e., at a time when the door frame is still accessible from the outside. This allows a larger number of functional modules to be pre-mounted on the frame, which can significantly simplify the assembly of the vehicle door on the door frame. Furthermore, the dimensions of the functional modules are no longer limited by the size of an opening in the inner door panel, allowing for greater freedom and improved functionality. During assembly, the module cassette can simply be moved along a straight line to its position on the door frame (or vice versa). Complex movement sequences, in which specific areas are threaded or maneuvered behind an overhang, are not necessary. For this reason, assembly can be significantly simplified and, for example, carried out with a (simple) assembly robot.

At least one functional module is mounted, for example, on the wet side of the carrier.

The support can have a circumferential edge, for example between the wet side and the dry side. It can be designed so that at least one functional module mounted on the support extends beyond the edge of the support. This allows for improved functionality of the functional modules without complicating installation, as maneuvering through an opening in the inner door panel is not necessary.

The modular cassette can include a sealing element, for example, running along the edge. This sealing element can form the sealing surface or an additional sealing surface. This enables a particularly reliable seal with a simple design. Alternatively or additionally, the carrier itself can form the sealing surface, and/or such a sealing element can be mounted, for example, on the door frame.

At least one functional module can be a functional module with a door drive, a radio The system includes a door lock module, a functional module with a mounting bracket for a door handle, and/or a functional module with at least one window regulator rail. Pre-assembling some or more, and in particular all, of these functional modules on the carrier allows for particularly easy assembly.

At least one functional module can alternatively or additionally include a functional module with a window pane. This allows for a further significant simplification of assembly, as the window pane no longer needs to be attached to the module cassette inside the vehicle door, but can be mounted to it beforehand.

For example, at least one functional module includes a reinforcing plate. Such a reinforcing plate can be supported on the outside of the inner door panel. This further simplifies installation on the door frame.

In a specific embodiment, this includes at least one functional module in the form of a side impact beam and/or a functional module in the form of an external shaft reinforcement to reinforce a shaft for a window pane.

The support can be made of a flat material, e.g. a sheet, such as a metal sheet, in particular a steel sheet, or an organosheet.

According to one aspect, a vehicle door is specified, comprising a door frame, a door outer skin, and the module cassette according to any of the embodiments described herein, wherein the sealing surface of the module cassette abuts a sealing surface of the door frame facing the door outer skin. Regarding the advantages, reference is made to the information above.

The outer door skin can be permanently attached to a frame (e.g., by screws, rivets, and/or welding) and be in contact with the frame. The frame is, for example, screwed to the door frame or otherwise permanently attached to it. Furthermore, the frame can be in contact with the door frame. This allows for particularly easy installation of the outer door skin onto the door frame, including the module cassette positioned between them.

For example, the door frame has an opening. This opening can be closed (from the outside) by the support for the module cassette. The opening reduces the weight. Furthermore, one or more of the functional modules can be positioned, at least partially, on the dry side.

According to one aspect, a vehicle is specified with a vehicle door according to any of the configurations described herein.

According to one aspect, a method for assembling a vehicle door is described. The method comprises providing a door frame having an inside and an outside; and mounting the module cassette, according to any of the embodiments described herein, with at least one pre-mounted functional module, on the outside of the door frame. Furthermore, the method may include mounting an outer door skin on the outside of the door frame, wherein the sealing surface of the module cassette rests against a sealing surface of the door frame facing the outer door skin. Regarding the advantages, reference is again made to the above information.

It can be arranged that, during the assembly of the module cassette, the module cassette is moved from a starting position spaced away from the door frame along a linear assembly direction towards the door frame until the sealing surface of the module cassette comes into contact with a sealing surface of the door frame. This allows the use of particularly simple tools, e.g., a robot.

When assembling the door outer skin, it can be arranged that the door outer skin is moved from a starting position spaced apart from the door frame and the module cassette along the assembly direction towards the door frame and the module cassette until the door outer skin or a frame attached to it comes into contact with the door frame. The same robot can be used for this as before.

For example, the assembly of the module cassette is carried out using an assembly robot. This allows for a particularly short assembly time and therefore high production rates.

The underlying idea of the proposed solution will be explained in more detail below using the examples shown in the figures.

This shows:

• 1 a modular cassette for a vehicle door with several functional modules, showing a window pane in an unmounted state;
• 2 the module cassette according to 1 with the pre-mounted window pane and a door frame of the vehicle door;
• 3 the door rough construction according to 2 Assembled modular cassette and a door outer skin;
• 4 the vehicle door after installation of the outer door skin according to 3 on the door frame with the modular cassette mounted on the door frame;
• 5 a vehicle with the vehicle door mounted on it according to 4 ; and
• 6A and 6B Assembly steps during the assembly of the vehicle door according to 4 .

1 shows a module cassette 1. The module cassette 1 is designed to be attached to a door structure, which is referred to below as door rough construction 20 (see e.g. 2 ) of vehicle door 2 (see e.g. 4 ) is to be defined. The module cassette 1 comprises a carrier 10 on which functional modules 11A-11F of the module cassette 1 are mounted and according to 1 are already partially assembled, particularly before the module cassette 1 has been fixed to the door frame 20, as shown in the 1 and 2 shown.

The carrier 10 has a splash-proof wet side 100, as well as a dry side 101 opposite the wet side 100. 1 shows the view of the wet side 100. With proper installation of the module cassette 1 in the vehicle door 2 and the vehicle door 2 in a vehicle 4 (see e.g. 5 The module cassette 1 – like the door frame 20 – has an inside and an outside. The inside faces the interior of the vehicle 4, and the outside faces an area outside the vehicle 4. The dry side 101 corresponds to the inside of the carrier 10, and the wet side 100 to its outside. The dry side is protected from moisture, especially rain and splash water. The wet side 100 can come into contact with water during rain, snowfall, or the like. For example, rainwater runs down a window pane 114 of the vehicle door 2 into the interior of the vehicle door 2, but only on the wet side 100 of the carrier 10, not on the dry side 101.

The carrier 10 has several fastening points 103 for attaching the carrier 10, including the pre-mounted functional modules 11A-11F, to the door frame 20 of the vehicle door 2. In this case, a large number of functional modules 11A-11F are pre-mounted on the carrier 10; however, depending on the vehicle 4's equipment, a smaller number of functional modules 11A-11F or even just one functional module 11A-11F could be mounted on it.

On the dry side 101 of the beam 10 there is a (in the view of the 1 not visible but e.g. in 6A (Illustrated) sealing surface 120 for sealing the dry side 101 against the wet side 100 on the door rough construction 20 is provided.

In this case, the sealing surface 120 is formed by a sealing element 12, which is attached to the support 10 along an edge 102 of the support 10. The sealing element 12 is a self-contained element, specifically a rubber seal. Alternatively, the sealing element 12 can also be pre-mounted on the door frame 20 or positioned between the two components during assembly, so that the support 10 itself also has a circumferential sealing surface, which then, for example, abuts the sealing element 12.

The previously mentioned edge 102 of the support 10 connects the wet side 100 with the dry side 101 of the support 10. The support 10 is a flat piece of material (e.g., made of plastic or sheet metal, in particular sheet steel or organosheet), with the two opposite large sides forming the wet side 100 and the dry side 101, and the narrow sides forming the edge 102. The edge 102 runs once around the outside of the support 10.

As previously described, several function modules 11A-11F are mounted on carrier 10. Each function module 11A-11F provides a function, and in this example, each module performs a different function for the other. Naturally, depending on the configuration of vehicle door 2, a larger or smaller number and a different selection of function modules 11A-11F may be mounted on the respective carrier 10. It may be intended that all components of function modules located in the door body between an inner door panel and an outer door skin are mounted on carrier 10 (via carrier 10 on the rest of the vehicle door 2). However, it could also be intended that one or more function modules, or one or more parts thereof, e.g., the window pane 114, are mounted only after the module cassette 1 has been installed. Carrier 10 can have mounting surfaces for a certain number of function modules 11A-11F, but not all of these need to be used.

In the present case, the module cassette 1 has a function module 11A with a door drive 110 (in 1 (illustrated with dashed lines). The door drive 110 is designed to exert a force on a support point on the body of the vehicle 4, e.g. with a suitable band, in order to open or close the vehicle door 2.

Module cassette 1 further comprises a functional module 11B with a door lock 111. The door lock 111 is designed to lock with a bolt, which is, for example, mounted on the body of the vehicle 4. An optional motorized opening mechanism is also provided.

The module cassette 1 also includes a functional module 11C with a bearing bracket 112 for a door handle 22. The door handle 22 is operatively connected to the door lock 111 via the bearing bracket 112.

The module cassette 1 further comprises a functional module 11D with two window regulator rails 113. The window regulator rails 113 are spaced apart from each other and attached to the support 10. The window regulator rails 113 are designed to guide the drivers of a window pane 114. This functional module 11D also includes a motor drive for moving the drivers along the window regulator rails 113 and thus for opening and closing the window pane 114. 1 The window pane 114 is shown in an unmounted state to allow a view of the components underneath. 2 Figure 1 shows the window pane 114 in the state mounted on the module cassette 1. Here, the window pane 114 is attached to the guides. This functional module 11D also includes a window guide 115. The window guide 115 guides one edge of the window pane 114. The window guide is attached to a lateral end of the support 10.

Furthermore, module cassette 1 comprises several functional modules 11E, 11F, each in the form of a reinforcement element, exemplified here by a reinforcement plate. One functional module 11E is designed as a side impact beam. The side impact beam extends diagonally across the beam 10. Another functional module 11F is in the form of an outer shaft reinforcement for reinforcing a shaft S (see e.g. 4 ) designed for window pane 114.

Module cassette 1 can include further functional modules, e.g. one with a loudspeaker or the like.

In 1 It is clearly evident that some of the functional modules 11A-11F mounted on the carrier 10 project laterally beyond the edge 100 of the carrier 10. For example, the window regulator rails 113 project beyond the carrier 10 at its upper edge, and the side impact beam projects beyond the carrier 10 at two spaced-apart edges. The functional modules 11A-11F project beyond the edge 102 of the carrier 10 in a direction parallel to the planes of the large surfaces of the carrier 10 (parallel to the plane in which the carrier 10 mainly extends). Several of the functional modules 11A-11F thus have a contour outside the sealing surface 120 of the carrier 10.

2 Figure 2 shows the previously mentioned door frame 20 of the vehicle door 2. The door frame 20 is made of one or more sheets of metal firmly connected to each other. The door frame 20 comprises an inner door part, which is shown below as an example in the form of an inner door panel 206, and a window frame 205. An inner shaft reinforcement 207 is provided between the inner door panel 206 and the window frame 205, which can also be considered part of the window frame 205. The support 10 is attached to the inner door panel 206. The closed window pane 114 fills the window frame 205.

The inner door panel 206 has an opening 203. The opening 203 is smaller than the support 10. With the functional modules 11A-11F pre-mounted on the support 10, the module cassette 1 could not be pushed through the opening 203 if the support 10 is aligned according to its final mounting position on the inner door panel 206. Furthermore, it would not be possible to move the functional modules 11A-11F, which protrude on the wet side 100, through the opening 203 without causing damage, while the support 10 remains on the other side of the opening.

The door frame 20 has an inside 201 (see e.g. 6A) and an outside 202 on. 2 shows the view of the outside 202. The outside 202 corresponds to the wet side 100.

Along a circumferential edge of the opening 203, the inner door panel 206 has a sealing surface 200. The sealing surface 200 serves to separate the wet and dry areas. The sealing surface 200 is located on the outer surface of the inner door panel 206.

The sealing surface 200 is self-contained. Furthermore, the inner door panel 206 has several fastening points 204 at the edge of the opening 203.

For installation, the module cassette 1 is attached to the inner door panel 206. The sealing surface 120 of the module cassette 1 seals against the sealing surface 200 of the door frame 20. Thus, the module cassette 1 closes the opening 203 in such a way that water is retained on the wet side 100 and does not reach the dry side 101.

The fastening points 103 of the carrier 10 are then flush with the fastening points 204 of the inner door panel 206. Fastening elements 24, Fasteners such as screws, rivets, plastic clips, or snap fasteners are then mounted at the fastening points 103 and 204, securing them together. In this example, the support 10 is screwed to the inner door panel 206 from the outside.

Furthermore, welding points can be provided, e.g. between the side impact beam and the gate structure 20 and/or the shaft reinforcement and the gate structure 20, whereby screw connections are also provided in these cases.

It is also evident that the window pane 114, when open (positioned next to the support 10), is located between the support 10 and the side impact beam. Furthermore, the window pane 114, when open, is located between the support 10 and the outer shaft reinforcement.

3 Figure 1 shows the door frame 20 with the module cassette 1 mounted on it, as well as a door outer skin 21. The door outer skin 21 comprises, for example, a sheet metal panel and, together with an outer surface 211, forms an outer surface of the vehicle door 2. An inner surface of the door outer skin 21, when mounted, faces the module cassette 1 and the inner door panel 206. The door outer skin 21 also has a recessed handle 210, in which the door handle 22 is located when mounted, by means of which the closed vehicle door 2 can be opened from outside the vehicle 4.

The outer door skin 21 is attached to the door frame 20 to form the vehicle door 2.

4 Figure 2 shows the assembled vehicle door 2. The vehicle door 2 therefore comprises the door shell 20, the door outer skin 21 and the module cassette 1, wherein the sealing surface 120 of the module cassette 1 rests against the sealing surface 200 of the door shell 20 facing the door outer skin 21.

The inner door panel 203 and the outer door skin 21 form a door frame, in which an interior space is created. The support and the functional modules 11A-11F are arranged in this interior space.

Furthermore, the vehicle door has a slot S for the window pane 114. The slot S is limited by the inner slot reinforcement 207 and the outer slot reinforcement (functional module 11F). When the window pane 114 is opened or closed, it is pushed (downwards or upwards) through the slot S.

5 The aforementioned vehicle 4 is shown as an example in the form of a passenger car. Vehicle 4 has a body that defines a vehicle interior 40. Passengers can enter and exit the vehicle interior 40. Several seats are arranged in the vehicle interior 40. Passengers can sit on these seats in the vehicle interior 40.

The vehicle 4 further comprises one or more vehicle doors 2 (here several, of which only one is illustrated), each designed and manufactured as described above.

Furthermore, with regard to the intended installation of vehicle door 2 in vehicle 4, a coordinate system can be defined for vehicle 4 and for vehicle door 2 and its elements. A longitudinal axis x of the vehicle extends from the rear of vehicle 4 to its front, i.e., along the direction of forward travel.

A (horizontal) transverse axis y of the vehicle extends perpendicularly to the longitudinal axis x between two opposing vehicle doors 2 of the vehicle 4. The vehicle vertical axis z is defined by being perpendicular to both the longitudinal axis x and the transverse axis y. The vehicle vertical axis z extends from the floor of the vehicle 4 to its roof.

Based on the 6A and 6B The procedure for assembling vehicle door 2 will now be explained in more detail.

The process involves providing a door frame 20 with an inside 201 and an outside 202, e.g., the door frame 20 as described above. In the later installed state of the vehicle door 2 on the vehicle 4, the inside 201 faces the vehicle interior 40, and the outside 202 faces outwards.

The method then comprises mounting the module cassette 1 described herein (including the pre-mounted functional modules 11A-11F) on the outside 202 of the door frame 20. Here, the module cassette 1 is moved from a starting position spaced apart from the door frame 20 along a straight mounting direction M towards the door frame 20 until the sealing surface 120 of the module cassette 1 comes into contact with the sealing surface 200 of the door frame 20, see Figure 1. 6A .

The mounting of module cassette 1 can be done as described in 6A This is illustrated by an assembly robot 3. The assembly robot 3 comprises an arm 30 (e.g., motor-driven or pneumatically operated) which performs a displacement movement along the assembly direction M. The arm 30 carries the pre-assembled module cassette 1 and moves it along the assembly direction M. The fastening elements 24 are then attached to secure the module cassette 1 to the door frame 20. This can also be done by the assembly robot 3, e.g., with arm 30 or another arm.

With regard to the subsequent installation position in vehicle 4, the mounting direction M runs parallel to the vehicle's transverse axis y. This allows for a particularly simple, straight mounting movement.

6B shows the door frame 20 with the module cassette 1 mounted on it. Furthermore, shows 6B The outer door skin 21. The outer door skin 21 is fixed to a frame 23. The assembly robot 3 (or another assembly robot) carries the outer door skin 21 with the frame 23 on its arm 30 (alternatively on another arm).

The procedure further includes mounting the outer door skin 21 on the outer surface 202 of the door frame 20. The sealing surface 120 of the module cassette 1 then rests against the sealing surface 200 of the door frame 20 facing the mounted outer door skin 21.

During the installation of the door outer skin 21, the door outer skin 21 is moved from a starting position spaced apart from the door frame 20 and the module cassette 1 along the installation direction M towards the door frame 20 and the module cassette until the frame 23 attached to the door outer skin 21 comes into contact with the door frame 20. The door frame 20 and the frame 23 are fixed together, in this case by means of screws.

The outer door skin 21 is then mounted on the frame 23, which in turn is screwed to the door shell 20.

Assembly in one axial direction allows for a simple, fully automated robot assembly.

Furthermore, a cover can be fitted to the inside. The module cassette 1 then has no visible surfaces, as it is covered on the inside by the cover and on the outside by the outer door skin 21.
