Description

The invention relates to a method for contacting a functionalized window pane with a window regulator of a vehicle door, the window pane having a first contact point, the vehicle door having a door shell and a door module carrying the window regulator, and the window regulator having a rail slider that can be moved along a guide rail and has a second contact point has contact point. The invention also relates to a vehicle door with a functionalized window pane.

A door body of a vehicle door generally has a door shell with a door frame and with an outer door panel forming the outer skin of the vehicle door, as well as a door inner lining on the inside of the vehicle connected to the outer door panel. The door frame can have a window frame for a window pane, or it can be designed without a frame. A cavity is formed as an assembly space between the inner door panel and the outer door panel, in which functional components of the vehicle door, such as a window winder, a door lock, an airbag, a loudspeaker or the like are arranged.

To assemble the functional components in the vehicle door, it is possible to preassemble such functional components on a carrier plate, also known as a door module carrier or unit carrier. The carrier plate equipped with the functional components is also referred to as a door module and is placed as a pre-assembled assembly on a corresponding assembly opening in the door frame in order to cover it, in particular to realize a wet room/dry room separation of the vehicle door. In particular, the electronics of the functional components are accommodated in the dry space, with the mechanical components in particular being integrated in the wet space. Overall, there are fewer components, the potential for errors is reduced and there is no longer any need to seal individual electronic functional elements. Furthermore, the carrier plate of the door module protects against moisture and also shields the interior of the vehicle against the ingress of dust and external noise. In addition, this door architecture creates a resonance chamber that improves the acoustics of the integrated loudspeaker.

Movable vehicle window panes are now usually moved between a closed position and an open position by means of actuating devices operated electrically or by an electric motor as (vehicle) window regulators. Such a window regulator usually includes a movable or adjustable rail slider as a driver or interface (connection point) with the window pane.

During the assembly of the vehicle door, the window pane is coupled to the window regulator or to the rail slider. For this purpose, the rail slider is moved into an upper assembly position below a door sill slot of the door shell, and the window pane is guided from above through the door sill slot and is mechanically coupled to the rail slider within the assembly space, for example latched or clipped.

Nowadays, in addition to ordinary window panes, so-called functionalized or electrified window panes are increasingly being installed in vehicle doors. A functionalized window pane is understood here and below in particular as electrically switchable or controllable (motor vehicle) glazing, i.e. a window pane with an electrically switchable or (controllable) functional layer, in particular an electrotransparent, a heatable, or a lightable layer. In other words, an in particular optical and/or thermal functional layer of the window pane is provided, the functions of which can be influenced, changed, switched or controlled by means of electrical control signals.

In order to control such functionalized window panes, they must be coupled to an energy source and/or a control device (controller) in the form of electronics in order to transmit the control signals. Particularly in the case of movable or adjustable window panes in a motor vehicle, for example a side window pane or a sunroof, the signal-transmission connection between the window pane and electronics entails a design and assembly-related outlay.

In particular, the electrical and/or signaling contact is usually only possible with great effort, since the contact points of the door module electronics are arranged within the closed installation space. After the door module and the window pane are installed in the door shell, the electrical transfer points or contact points between the door module and the functionalized window pane are no longer accessible in the field of vision, so that contacting when installing the window pane is disadvantageously more difficult. Nowadays, this means that only fixed-glazed functionalized window panes, i.e. without a window regulator, are implemented in series applications.

The invention is based on the object of specifying a particularly suitable method for contacting a functionalized window pane with a window regulator of a vehicle door. In particular, the aim is to reduce the outlay in terms of design and installation technology for the electrical and/or signaling contacting of the functionalized window pane. Furthermore, assembly and connection of the window pane on the window regulator should be as simple and cost-reduced as possible. The invention is also based on the object of specifying a particularly suitable vehicle door.

With regard to the method, the object is achieved with the features of claim 1 and with regard to the vehicle door with the features of claim 8. Advantageous refinements and developments are the subject of the dependent claims.

The advantages and configurations given with regard to the method can also be transferred to the vehicle door and vice versa. Insofar as method steps are described below, advantageous configurations for the vehicle door result in particular from the fact that it is designed to carry out one or more of these method steps.

The method according to the invention is intended for contacting, ie for the electrical and/or signaling coupling or interconnection, of a functionalized window pane with a window regulator of a vehicle door, and is also suitable and designed for this. In this case, the window pane has a first contact point as an interface or transfer point. The vehicle door has a door shell and a door module that carries the window regulator, the window regulator being designed with a guide rail and a rail slider mounted thereon so that it can move. The rail slider is suitable and set up for mechanical and electrical or signaling coupling with the window pane. In this case, the rail slider has a second contact point for connection or coupling to the first contact point of the window pane. The second contact point is suitably coupled to an energy source and/or a control device (controller) of the door module or the window lifter, so that in the contacted state control signals can be transmitted from the control device to the window pane.

The method according to the invention is carried out here during assembly of the vehicle door. In particular, the method is carried out when the vehicle door—apart from the window pane—is essentially completely assembled. In other words, the method relates in particular to one of the last assembly steps in the course of assembly or the manufacture of the vehicle door.

According to the method, the rail slider is first brought into a predetermined position in which the functionalized window pane is inserted into the door shell in such a way that the two contact points are arranged adjacent to one another. The rail slider is positioned here, for example, on an upper edge of the door module below a sill in the door shell of the door shell, with the window pane being passed through the sill in the door sill with a lower window edge having the (first) contact point. It is conceivable here, for example, for the rail slider to be moved or adjusted to the specified or predefined position in the course of the method. However, it is also conceivable that the rail slider is already in the predetermined position when the door module or the vehicle door is delivered. An adjacent arrangement of the contact points is to be understood here in particular as a positioning of the two contact points arranged next to one another and/or one above the other.

The door shell and/or the door module have an assembly opening through which an auxiliary tool is guided. An auxiliary or additional tool is to be understood in particular as a manually or automatically controlled tool for contacting the rail slider with the window pane. The auxiliary tool is therefore intended and set up to bring about, in particular, permanent contact between the contact points within the assembly space of the door shell.

For this purpose, the rail slider is guided together with the functionalized window pane from the predetermined position into an assembly position or assembly position, the contact points being contacted with one another in the assembly position by means of the auxiliary tool. This means that the auxiliary tool inserts the contact points or contact partners of the rail slider and the window pane into one another. For the purpose of maintenance or for service or repair work, it is possible, for example, for decontacting or disassembly to take place in the same way using an auxiliary tool inside the assembly space.

As a result, a particularly suitable method for contacting a functionalized window pane with a window regulator of a vehicle door is implemented.

In particular, a simple and cost-reduced contacting of the window pane realized within the closed assembly space of the door shell. In this way, contact can be reliably and reliably implemented despite the difficult accessibility of the contact points.

The contact points are designed, for example, as a plug-in connection, ie as a plug-socket pair. This enables a structurally simple and reliable contacting.

After the contact points have been contacted, the auxiliary tool is preferably removed from the assembly space via the assembly opening and the assembly opening is then closed.

The conjunction “and/or” is to be understood here and in the following in such a way that the features linked by means of this conjunction can be designed both together and as alternatives to one another.

Information regarding the spatial directions is given below, also in particular in a coordinate system of the motor vehicle (vehicle coordinate system) with regard to an exemplary installation situation of a window lifter in a side door of the motor vehicle. The abscissa axis (X-axis, X-direction) is oriented along the longitudinal direction of the vehicle (driving direction) and the ordinate axis (Y-axis, Y-direction) along the vehicle transverse direction, and the applicate axis (Z-axis, Z-direction) along the vehicle height .

In an advantageous embodiment, a mounting position is used on a lower edge of the door module facing the ground, which is not visible outside the vehicle door or the door shell. In other words, the assembly position is arranged within the assembly space of the door shell, which is not visible from the outside. This means that the assembly opening is also provided in particular on the lower edge of the door module or the door shell, so that the insertion opening for the auxiliary tool is arranged close to the assembly position. This enables simple and reliable contacting.

In an expedient embodiment, the window pane is mechanically coupled to the rail slider when it is inserted into the door shell. This enables the window pane to be easily guided or adjusted from the predetermined position to the assembly position. In a suitable embodiment, the rail slider has a driver for mechanical coupling. In the context of the invention, driver initially means in general a connecting element between the window lifter or the rail slider and the window pane.

In one possible embodiment, the auxiliary tool is guided axially or perpendicularly through the assembly opening. In particular, the auxiliary tool is guided along the Z-direction from below into the assembly space to the assembly position. This enables the auxiliary tool to be guided easily.

In a possible variant, the auxiliary tool is first pushed through the assembly opening or introduced into the assembly opening for contacting. The rail slider with the window pane is then moved into the defined or known assembly position. In the assembly position, the contact points are guided towards each other in a targeted manner or pressed or pressed against one another with the help of the auxiliary tool. In this case, the auxiliary tool is guided and actuated manually, for example, so that tolerance-related inaccuracies between the contact points can be compensated for in a simple manner.

In an alternative variant, the auxiliary tool for joining the contact points is fixed in the assembly opening. This means that the auxiliary tool for contacting is stationary, module-fixed, fixed or stationary. In a suitable development, the stationary auxiliary tool is arranged in the area of the assembly position in such a way that when the rail slider is moved into the assembly position, the contact points are contacted with one another. This means that the rail slider is moved onto the auxiliary tool in a defined manner in such a way that the contact points are contacted with one another.

In other words, the auxiliary tool is inserted and fixed in the assembly opening. The rail slider with the window pane is then lowered onto the auxiliary tool in a defined manner, so that the contact points make contact with one another, ie, for example, are pushed into one another. In this variant, the contacting takes place in particular automatically when the rail slider is lowered. In this case, the contacting of the contact points is ensured in particular by means of a force control.

In an expedient embodiment, the second contact point is designed to be movable relative to the rail slider. In this case, the second contact point is moved by means of the auxiliary tool when making contact in such a way that the second contact point and the first contact point are electrically and/or mechanically connected to one another. In particular, the second contact point is arranged or attached to the rail slider that the contact place against the auxiliary tool as an axial stop when lowering the rail slider. As a result, the second contact point is held at the installation site at a height or Z position by means of the auxiliary tool, while the rail slider with the window pane is lowered further. As a result, the first contact point of the window pane is pushed or pulled onto the fixedly held first contact point, so that particularly simple, reliable and cost-reduced contacting is ensured, particularly in the case of an embodiment as a plug-in connection.

The vehicle door according to the invention is designed, for example, as a side door of a motor vehicle. The vehicle door has a window regulator with a functionalized window pane with a first contact point and with a rail slider coupled to the window pane with a second contact point. The window lifter is mounted on a door module arranged in the door shell, with the first and second contact points being connected to one another electrically and/or in terms of signal transmission. In this case, the door shell and/or the door module have an assembly opening for the passage of an auxiliary tool for contacting the contact points. As a result, a particularly suitable vehicle door is realized. According to the invention, at least one assembly opening is thus made in the door shell and/or in the door module, so that simple contacting according to the method described above is made possible.

In a preferred embodiment, the rail slider and/or the window pane has contours or geometries for guiding and centering or positioning the auxiliary tool. In other words, contours or geometries are provided at the contacting point, with which the auxiliary tool is centered and guided to the connector in a targeted manner in the course of the method according to the invention. This ensures reliable and dependable contacting. The (guide) contours or geometries are preferably provided on the rail slider.

In one possible embodiment, the window pane has a pane adapter for contacting and mechanical coupling to the rail slider. This means that the first contact point and spaced-apart mechanical contours for mechanical coupling to the rail slider are provided on the disc adapter.

Exemplary embodiments of the invention are explained in more detail below with reference to a drawing. It shows in schematic and simplified representations:

• 1 until 3 in successive representations a method for contacting a functionalized window pane with a vehicle window regulator in a first embodiment, and
• 4 until 6 in successive representations the method according to a second embodiment.

Corresponding parts and sizes are always provided with the same reference symbols in all figures.

In the 1 until 3 A method is shown for contacting a functionalized window pane 2 with a window regulator 4 of a vehicle door 6 . In the schematic and simplified representations, the electric window lifter 4 is designed as an adjusting device for the (vehicle) window pane 2 .

The window lifter 4 has a servomotor 8 which acts on the window pane 2 by means of a servomechanism. In this embodiment, the adjusting mechanism has two guide rails 10 , each with a rail slider 12 , 14 coupled to the window pane 2 .

When the servomotor 8 is actuated, the window pane 2 is moved in its (pane) position. The window pane 2 is reversible between an in 1 shown closed position, which represents the highest possible position, and an in 2 and 3 shown open position, which represents the lowest possible position, movable.

The window pane 2 has a pane adapter 16 with a mating connector as a contact point 18 on its lower edge. In this case, the rail slider 14 has a slider adapter 20 with a plug as the contact point 22 and a driver 24 as a mechanical coupling to the window pane 2 . The contact point 22 is mounted on the slider adapter 20 in an axially displaceable manner.

The driver 24 has an unspecified extension or lug for in particular positive and/or non-positive attachment, in particular for latching or clipping, with a mechanical contour of the window pane 2 or the pane adapter 16 . The mechanical contour of the window pane 2 is in particular a hole-like recess or receptacle in which the driver 24 engages in a positive and/or non-positive manner. The contact points 18, 22 are suitable and set up for an electrical and/or signal transmission plug-in connection.

The window regulator 4 is mounted on a carrier plate of a door module 26 which is arranged in a door shell 28 of the vehicle door 6 . The contact point 22 is suitably coupled to an energy source (not shown in detail) and/or a control device (controller) of the door module 26 or the window regulator 4, so that control signals can be transmitted from the control device to the window pane 2 in the contacted state.

Below is the assembly and contacting of the window pane 2 with the window regulator 4 according to a first embodiment of the method based on 1 until 3 explained in more detail.

According to the method, the rail slider 14 is first brought into a predetermined position in which the functionalized window pane 2 is inserted into the door shell 28 in such a way that the two contact points 18, 22 are arranged adjacent to one another. The rail slider 14 is in this case positioned, for example, on an upper edge of the door module 26 below a door sill slot of the door shell 28 , which is not described in any more detail. In particular, the rail slider 14 is brought into the closed position of the window lifter 4 .

It is conceivable here, for example, that the rail slider 14 is moved into the closed position during assembly. However, it is also conceivable that the rail slider 14 is already in the closed position when the door module 26 or the vehicle door 6 is delivered.

The window pane 2 is inserted with the lower edge of the window into the door sill slot of the door shell 28 . The driver 24 clips or latches to the window pane 2 or to the pane adapter 16 so that the window pane 2 is mechanically connected to the rail slider 14 .

The door shell 28 and/or the door module 26 have an assembly opening 30 as a through-opening for an auxiliary tool 32 . The mounting opening 30 is arranged on an underside or bottom edge of the vehicle door 6 .

Like in the 1 and in the 2 As can be seen, the auxiliary tool 32 is pushed in axially through the assembly opening 30 . The rail slider 14 is then moved with the window pane 2 into a defined or known assembly position. The assembly position corresponds to the open position of the window regulator 4, i.e. the lowest position of the rail slider 14 on the guide rail 10.

In the assembly position, which is not described in more detail, the contact points 18, 20 are guided towards one another in a targeted manner or pressed or pressed against one another with the aid of the auxiliary tool. For this purpose, the auxiliary tool 32 is pushed axially against the contact point 22 from below, and the contact point 22 is thus inserted into the contact point 18 ( 3 ). In this case, the auxiliary tool 32 is guided and actuated manually, for example.

The rail slider 14 and/or the window pane 2, in particular the slider adapter 20 and/or the pane adapter 16, have contours or geometries, not shown in detail, for guiding and centering or positioning the auxiliary tool 32. The contacting and joining of the window pane 2 with the rail slider 14 takes place in particular in a closed assembly space of the door shell 28, so that the contact points 18, 22 are not optically visible from the outside. The contours or geometries simplify “blind” contacting by means of the auxiliary tool 32, so that reliable contacting in the assembly position is always ensured.

In the 4 until 6 a second exemplary embodiment of the wafer contacting according to the method is shown and explained in more detail below.

In this variant, the auxiliary tool 32' is introduced into the assembly opening 30 ( 4 ), and to join the contact points 18, 22 fixed or stationary in the mounting opening 30 ( 5 ). As in 6 As can be seen, the head of the auxiliary tool 32' is arranged in the region of the assembly position such that the rail slider 14 moves in a defined manner onto the auxiliary tool 32' when moving from the closed position to the open position, i.e. when moving from the specified position to the assembly position or is lowered so that the contact points 18, 22 are contacted with each other. In this variant, the contacting thus takes place in particular automatically when the rail slider 14 is lowered. The contacting of the contact points 18, 22 is ensured here in particular by means of a force control.

The invention is not limited to the exemplary embodiments described above. On the contrary, other variants of the invention can also be derived from this by a person skilled in the art without departing from the subject matter of the invention. In particular, all of the individual features described in connection with the exemplary embodiments can also be combined with one another in other ways without departing from the subject matter of the invention.
