Description

The invention relates to a window lifter assembly device for assembling a functionalized window pane. The invention further relates to a mounting element of such a mounting device and a window lifter with such a mounting device.

A functionalized window pane is understood here and in the following to mean, in particular, electrically switchable or controllable (motor vehicle) glazing, i.e. a window pane with an electrically switchable or controllable functional layer, in particular an electrotransparent, heatable or luminous layer. In other words, an especially 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.

To control such functionalized window panes, they have to be coupled to an energy source and / or a control device (controller) as electronics for the transmission of the control signals. In particular in the case of movable or adjustable window panes of a motor vehicle, for example a side window pane or a sliding roof, the signal transmission connection between the window pane and the electronics entails a construction and assembly effort.

The invention is based on the object of specifying a particularly suitable assembly device for a window regulator. In particular, the design and assembly effort should be reduced when using functionalized window panes. Furthermore, the simplest and most cost-effective assembly and interconnection of the window pane on the window regulator should be implemented. The invention is also based on the object of specifying a particularly suitable mounting element for such a mounting device and a particularly suitable window lifter.

With regard to the assembly device, the object is achieved according to the invention with the features of claim 1 and with regard to the assembly element with the features of claim 9 and with regard to the window regulator with the features of claim 10. Advantageous refinements and developments are the subject of the dependent claims. The advantages and refinements cited with regard to the assembly device can also be applied analogously to the assembly element and / or the window lifter and vice versa.

The mounting device according to the invention is suitable and designed for mounting a functionalized window pane on a window regulator. The window pane here has an electrical contact point as a connection area.

The assembly device has a strip-shaped assembly element which is coupled or can be coupled to at least one driver (rail slider) of the window regulator. In the context of the invention, a driver is generally to be understood as a connecting element between the window lifter and the assembly device, which guides the assembly device adjustably along an adjustment path in order to move the window pane in the assembled state along the adjustment path between a closed position and an open position.

The mounting element has electronics for the electrical control of the window pane, which electronics are coupled or can be coupled with the electrical contact point of the window pane. The electronics have, for example, a controller, that is to say a control unit, which is generally designed - in terms of program and / or circuitry - to generate electrical control signals during operation to influence, change or control the window pane or a function of the window pane. The electronics here have electrical contacts as a mating contact or mating contact point for the contact point of the window pane.

The mounting element and the window pane are also provided with corresponding joining contours as positive-locking positioning aids.

A “form fit” or a “form fit connection” between at least two interconnected parts is understood here and in the following in particular to mean that the interconnected parts are held together at least in one direction by direct interlocking of contours of the parts themselves or by indirect interlocking takes place via an additional connecting part. The "blocking" of a mutual movement in this direction is therefore due to the shape.

The assembly device according to the invention is thus designed in particular as an electrified overall pane adapter of the window regulator, that is to say as a mechanical and signaling or electrical interface between the window regulator and the window pane. A particularly suitable assembly device is thereby implemented.

The assembly device or the overall pane adapter enables, on the one hand, the mechanical positioning of the window pane in relation to the window regulator and its mechanical coupling to the at least one driver (rail slider) of the window regulator. Furthermore, the electronics integrated in the overall pane adapter realize a particularly simple and cost-reduced signaling coupling with the window pane.

The mounting element is, for example, movably coupled or can be coupled to the at least one driver. This means that the coupling takes place in particular by means of an elastic coupling part which, for example, enables play or tolerance compensation between the assembly element and the at least one driver in the course of assembly or coupling. The mounting element can, however, also be fixedly or rigidly coupled to the driver, for example, the mounting element being or can be coupled to the at least one driver, for example by means of a clamp connection.

The window pane has, in particular, optical and / or thermal functions. For example, the window pane is electrotransparent and / or can be illuminated, this means that adjustable or controllable darkening or tinting or lighting of the window pane is made possible by means of the electronics. Additionally or alternatively, it is conceivable, for example, that the window pane can be heated.

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

In an advantageous embodiment, the electronics and the joining contours are suitable and set up so that when the window pane is placed on the assembly element along an installation direction that is essentially perpendicular to the assembly element, the window pane is forcibly guided by the joining contours into a predetermined or desired assembly position, and the electrical contact between the electronics and the contact point is effected essentially at the same time.

In other words, the window pane is blindly installed, in which the window pane is positioned and electrically contacted essentially at the same time. The joining contours of the window pane and the assembly element are thus essentially designed as guide contours for blind assembly. The joining contours and electronics are thus designed in particular as a guided disk holder and disk contact. This means that the mechanical and electrical contacting of the window pane with the window lifter or the electronics takes place essentially automatically when the window pane is placed or pushed onto the mounting element. In particular, a plug-in assembly and plug-in contacting of the window pane with the window regulator or the assembly element takes place.

As a result, a particularly suitable assembly device is implemented in which the assembly and interconnection of the functionalized window pane essentially takes place in one assembly step. In other words, a particularly simple and cost-reduced and essentially tool-free assembly and connection of the window pane on the window regulator is made possible.

An assembly direction oriented essentially perpendicular to the assembly element is also to be understood here as assembly directions which are oriented inclined at a certain angle with respect to the vertical. In particular, assembly directions are to be understood here which are, for example, slightly tilted or pivoted relative to the vertical to compensate for assembly tolerances. A substantially vertical mounting direction is preferably to be understood as a direction which deviates by less than 10 ° from the vertical.

“The electrical contact is made” or the “electrical contact is made” is understood here and below in particular to mean that the electrical contacts and mating contacts of the electronics and the window pane are aligned with one another. The electrical contact is preferably also made directly here. In other words, the contact is preferably made in an assembly step. Alternatively, it is possible, for example, for the contact to be made in several assembly steps, with the electronics and the contact point initially being arranged in a pre-position in the case of blind assembly, and then generating a contact pressure between the electrical contacts, for example with the addition of a tool which couples or connects the electronics and the window pane with one another in an electrically or signal-conductive manner.

In the following, information with regard to the spatial directions is also given in particular in a coordinate system of the motor vehicle (vehicle coordinate system) with regard to an exemplary installation situation of a window regulator in a side door of the motor vehicle. The abscissa axis (X-axis, X-direction) is oriented along the longitudinal direction of the vehicle (direction of travel) and the ordinate axis (Y-axis, Y-direction) along the transverse direction of the vehicle and the application axis (Z-axis, Z-direction) along the vehicle height.

In a suitable embodiment, the assembly element is coupled to the at least one driver when the window pane is placed or assembled. This ensures particularly simple and reliable assembly and interconnection.

In a preferred application, the window lifter and the assembly element are arranged in a door module or a door assembly of a vehicle door during assembly. In other words, the pane is installed in particular when the window lifter is installed in the door shell. The mounting element is oriented essentially along the longitudinal direction of the vehicle and has approximately the dimensions of a lower window edge on which the contact point is arranged. The mounting direction is along the vehicle height ( Z ) oriented so that the window pane is blindly mounted from above and electrically connected at the same time.

Window panes are typically permanently coupled to a pane adapter and can be coupled as a preassembled assembly to the drivers of the window regulator. In contrast to this, the overall pane adapter according to the invention or the mounting element is essentially part of the window regulator. In particular, the assembly element and the window lifter are a pre-assembled assembly with regard to the assembly and interconnection of the window pane. The mounting element is therefore preferably first attached to the at least one driver, for example by means of a clip connection, before the window pane is mounted.

In a preferred development, the assembly element is coupled or can be coupled to two drivers of the window regulator. The strip-shaped or elongated assembly element is here flexibly or movably coupled to a respective rail-guided driver (rail slider) of the window regulator, particularly in the area of the opposite end faces. As a result, the assembly element is supported in a stable manner essentially at two points, so that reliable and simple assembly and contact with the window pane is ensured.

In an expedient embodiment, the electronics are attached to the mounting element in a modular, replaceable manner. In other words, the electronics have a modular design and are fastened or fastened to the mounting element in an exchangeable manner. The exchangeable electronics make it possible in a simple manner to flexibly adapt the assembly device to different functionalized window panes, that is to say to window panes with differently integrated functions. In each case, electronics are preferably used with which the desired functions of the respective window pane can be controlled. The assembly element thus has a modular structure, at least with regard to the electronics, so that a high degree of prefabrication is made possible during assembly, whereby assembly costs and cycle times when assembling the window pane are advantageously reduced.

In one possible embodiment, the electrical contact between the electronics of the mounting element and the contact point of the window pane is implemented in the manner of zero force detection. This means that the electrical contacts of the electronics and the contact point are designed as Zero Insertion Force (ZIF) bases. As a result, when inserting or removing the window pane or the contact point in the electronics, essentially no compressive or tensile forces are required, so that a particularly simple and cost-reduced assembly and connection of the window pane is ensured. Furthermore, the window pane can be easily detached and de-contacted in the event of servicing, that is to say during maintenance or repair.

In a suitable embodiment, the mounting element has a sealing element for sealing the contact point of the window pane. The sealing element thus seals the electrical contact between the window pane and the electronics in the assembled state. As a result, in addition to the mechanical and electrical contacting of the window pane, the sealing of the contact point is also integrated into the mounting element or the overall pane adapter. The assembly element thus has a particularly high level of functional integration, as a result of which the window pane can be implemented in a comparatively simple and inexpensive manner.

The assembly element is designed, for example, as an injection-molded part, the sealing element being attached to it in a two-component injection molding process.

In an alternative embodiment, the window pane is provided with a seal for the contact point.

An additional or further aspect of the invention provides that the joining contours of the window pane are made in one piece, i.e. in one piece or monolithically, are formed on this. As a result, no additional or separate components are necessary, so that the window pane has a particularly simple and inexpensive structure.

In a conceivable embodiment, the joining contours of the window pane are designed as cutouts, for example as approximately triangular cutouts. The corresponding joining contours of the mounting element are designed as projections which are shaped complementarily to the recesses and which are formed on the mounting element in a protruding manner in the direction of the window pane, that is to say against the mounting direction. The triangular design of the joining contours ensures, on the one hand, a reliable forced guidance when the window pane is placed or inserted, so that a simple blind assembly that is reduced in effort is made possible. The triangular recesses of the window pane thus act as funnel-like or funnel-shaped depressions or (joining) receptacles for the corresponding extensions, which ensure blind assembly or “self-locating” contact. Furthermore, the joining contours in the joining or assembly state of the window pane provide a reliable form fit.

The joining contours are preferably formed in one piece, that is to say in one piece or monolithically, on the assembly element.

In an alternative embodiment, it is conceivable, for example, that the lower edge of the window pane has joining contours that protrude upwards, the joining contours of the assembly element being designed as corresponding (joining) receptacles. Here it is possible, for example, for the joining contours of the window pane to be designed as additional, separate adapters which are fastened to the window pane.

The mounting element according to the invention is suitable and set up for a mounting device described above. The approximately elongated or strip-shaped assembly element has electronics for the electrical control of a functionalized window pane, which is coupled or can be coupled with an electrical contact point of the window pane for signaling purposes. The assembly device also has, in particular, one-piece, that is, one-piece or monolithic, molded joining or guide contours which interact with the joining contours of the window pane as a positive positioning aid, in particular with regard to blind assembly. A particularly suitable assembly element is thereby implemented.

The window regulator according to the invention is designed as a motor vehicle window regulator, for example for a side door. The window lifter has a mounting device described above or a mounting element described above. As a result, a particularly simple, time-saving and inexpensive assembly and interconnection for functionalized window panes is realized.

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

In the 1 and in the 2 is a mounting device 2 a window regulator 4th for mounting a functionalized window pane 6th shown. The assembly device 2 and the window regulator 4th are preferably arranged in a door module or a door assembly of a motor vehicle side door.

The window regulator 4th has an adjusting mechanism shown in detail with two parallel guide rails 8th on each of which a driver 10 is displaceably movable along the respective rail longitudinal direction.

In the following, information with regard to the spatial directions is also given in particular in a coordinate system of the motor vehicle (vehicle coordinate system) with regard to an exemplary installation situation of a window regulator 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 transverse direction of the vehicle and the application axis (Z-axis, Z-direction) along the vehicle height .

The guide rails 8th are at an angle to the vehicle height direction Z arranged inclined. The guide rails 8th are along the longitudinal direction of the vehicle X arranged spaced from one another, with an elongated, approximately strip-shaped mounting element 12 on the carriers 10 is attached. The mounting element 12 extends essentially over the entire width of the pair of guide rails.

For mechanical coupling to the driver 10 has the mounting element 12 in the area of the driver 10 one at a time along the height of the vehicle Z rising boom 14th on which a fastening device 16 for non-destructive locking or clip fastening with the drivers 10 is provided.

The window glass 6th is with a functional layer 18th for performing optical and / or thermal (pane) functions. The functions can be controlled or adjusted or changed by means of electrical signals. The window pane shows the signaling coupling 6th or the functional layer 18th an electrical contact point 20th with an unspecified number of electrical contacts, only four contacts being shown by way of example in the figures. The contact point 20th is on one of the windows 4th facing lower edge of the window 22nd arranged.

For controlling the window pane 6th or their functional layer 18th has the mounting element 12 a (disc) electronics 24 on. The Electronic 24 is preferably modularly interchangeable on the mounting element 12 attached. The Electronic 24 has electrical contacts (not shown in more detail) as mating contacts or mating contact points for signaling and electrical coupling with the contact point 20th , as well as a controller that is a control device or control electronics, with which electrical control signals for the functional layer 18th are producible.

The contacts of the electronics 24 and the contact point 20th are designed, for example, in the manner of zero force detection.

The mounting element 24 furthermore has two joining contours arranged at a distance 26th on which about opposite to the booms 14th are molded.

The joining contours 26th are thus essentially on the opposite end faces of the mounting element 24 arranged.

In the in 1 and in 2 The illustrated embodiment are the joining contours 26th than along the vehicle height Z , so in the direction of the window pane 6th , protruding extensions executed. The joining contours 26th have an approximately triangular cross-sectional shape in the XZ plane shown.

The window glass 6th points at the lower edge of the window 22nd two complementary shaped, i.e. roughly triangular, joining contours 28 as joining recordings, which in this embodiment as two recesses or depressions in the lower edge of the window 22nd are introduced. Due to the complementary design of the joining contours 26th and 28 is an operationally reliable form fit between the window pane in the assembly or joint state 6th and the mounting element 12 realized.

How with the 1 and 2 is comparatively clearly visible, the assembly of the window pane takes place 6th along a perpendicular to the mounting element 12 oriented mounting direction M. which are essentially parallel to the vehicle height Z is oriented. The window glass 6th So is along the assembly direction M. on the mounting element 12 put on or (put on). The joining contours take effect here 26th of the mounting element 12 in the joining contours 28 the window pane. Because of the triangular configuration, the window pane is essentially forced to move 6th realized with the window pane 6th by means of the joining contours 28 at the joining contours 26th slides off and is brought into a desired assembly position ( 2 ). In the course of this mechanical positioning or contacting, electrical contacting of the electronics takes place essentially at the same time 24 and the contact point 20th or the functional layer 18th .

In other words, blind assembly takes place, that is, “self-locating” mechanical and electrical or signaling contacting of the window pane 6th on the window regulator 4th at which the window pane 6th is positioned and electrically contacted essentially at the same time. The joining contours 28 the window pane 6th and the joining contours 26th of the mounting element 12 are therefore essentially designed as guide contours for blind assembly. The joining contours 26th , 28 and electronics 24 are thus designed in particular as a guided disc holder and disc contact. This is the mounting element 12 essentially as an electrified overall pane adapter for the window regulator 4th executed.

The mounting element preferably has 12 in the field of electronics 24 a sealing element, not shown in detail, by means of which in the assembled state ( 2 ) the electrical contact between the electronics 24 and the window pane 6th is sealed essentially fluid-tight.

The following is based on the 3 and the 4th a second embodiment of the mounting device 2 ' explained in more detail.

In this embodiment the joining contours are 26 ' of the mounting element 12 ' designed as approximately triangular or funnel-shaped joining receptacles. The window glass 6th is here with two adapters as joining contours 28 ' provided, which at the lower edge of the window 22nd are attached. The joining contours 28 ' point in the XZ plane on your window regulator 4th facing free end has an approximately trapezoidal or frustoconical cross-sectional shape, which in the course of the blind assembly on the joining contours 26 ' in the desired mounting position ( 4th ).

The invention is not restricted to the exemplary embodiments described above. Rather, other variants of the invention can also be derived from this by the 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.
