DOOR MODULE AND HOUSING ASSEMBLY OF A VEHICLE WINDOW REGULATOR

Description

[0001] The invention relates to a housing assembly for a door module of a vehicle door of a motor vehicle, according to the preamble of claim 1. Such a housing assembly is known, for example, from DE 10 2016 212 041 B4. It further relates to a door module with such a housing assembly.

[0002] A motor vehicle door typically comprises a door frame (often referred to as the door shell), an outer door panel forming the outer skin of the vehicle door, and an inner door panel or inner door panel connected to the door frame on the inside of the vehicle. A cavity is formed between the outer door panel (the outer door panel) and the inner door panel as an assembly space for functional elements or components of the vehicle door.

[0003] The functional components of a vehicle door, such as a window lifter or window lift assembly, a pressure sensor for a side airbag, door control electronics, a loudspeaker, a door lock, operating units, or the like, are generally pre-assembled on a carrier plate of a door module, also known as an assembly carrier. The assembled carrier plate is then attached to the door shell, covering a panel in the door frame that also serves as an assembly opening. The door module, as a carrier plate, particularly equipped with the window lifter (the window lift assembly), also serves, in particular, to separate a wet space formed between the outer door skin (the outer door panel) and the door module from a dry space of the vehicle door formed between the door module and the inner door panel (the inner door panel).

[0004] Such a window lifter for a vehicle door, for example, is designed with a cable system for raising and lowering a (window) pane. Single-strand window lifters with only one guide rail (single-strand application) or double-strand window lifters with two parallel guide rails (double-strand application) can be used. Such a window lifter, also known as a cable window lifter, has at least one so-called rail slider or (pane) driver, which is connected to the (window) pane and guided along at least one guide rail by means of a driven cable system.The cable system of the window lifter usually has a cable pull formed from at least one pull cable, which on the one hand wraps around a cable drum with typically several windings and is wound up and unwound by this, and on the other hand is guided to the or each (window) driver or rail slider with multiple deflections and is fixed there.

[0005] The window lifter or cable drive typically consists of an electric motor with a coupled gearbox, particularly a worm gear as a 90° deflection gear. In single-wire applications, the cable drive is mounted on the support plate of the door module at a distance from the single guide rail. In double-wire applications with two parallel guide rails, the cable drive is typically arranged between the two guide rails of the door module and mounted on the support plate.

[0006] When installing the cable drive, the electric motor can be located on the wet room side (wet room motor) or on the dry room side (dry room motor). The electric motor with coupled gearbox can be installed using a housing assembly, known for example from the aforementioned DE 10 2016 212 041 B4, with a housing section accommodating the gearbox coupled to the electric motor and a housing section accommodating the cable drum coupled to the cable drive. The housing parts of the housing assembly can be screwed together via through-holes in the support plate using screw elements (screws), with the screw heads being provided in the wet room-side housing section and the screw threads being provided in the dry room-side housing section or being incorporated into them during the screwing process.

[0007] A first housing section, which accommodates the cable drum coupled to the cable drive, can be arranged on the wet room side, while a second housing section, which accommodates the gearbox coupled to the electric motor, is arranged on the dry room side of the support plate. The housing sections must therefore be screwed together from the wet room side towards the dry room, so that if the electric motor and / or the gearbox of the cable drive are dismantled, for example for repairs, the screw connections between the two housing sections can no longer be loosened, as the screw elements or screws are no longer accessible. In addition, the typically self-locking gearbox of the cable drive prevents displacement or loosening if the electric motor is defective.Lower the window pane to release the mechanical interface or connection of the window pane with the (pane) driver or rail slider of the window regulator and to remove the door module or the carrier plate with the installed window regulator from the vehicle door in order to dismantle or repair the electric motor.

[0008] The invention is based on the object of specifying a particularly suitable housing assembly for an electromotive cable drive of a window lifter, in particular for a door module with a window lifter for a vehicle door mounted on a support plate. This should provide a screw connection between two housing parts of the housing assembly of an electromotive cable drive of the window lifter from a dry room side and / or from a wet room side of the door module. In particular, it should be possible to loosen the screw connection from the dry room side, for example for disassembly or repair of the cable drive. Furthermore, a door module with such a housing assembly with two housing parts of a cable drive of a vehicle window lifter that can be screwed together should be specified.

[0009] With regard to the housing assembly, the stated object is achieved according to the invention with the features of claim 1 and with regard to the door module with the features of claim 8. Advantageous embodiments and further developments are the subject of the subclaims.

[0010] The door module, which is intended for a vehicle door of a motor vehicle and is particularly configured for a wet-dry compartment separation in the vehicle door, has a support plate for a window lifter assembly, also referred to below as a window lifter or window lifter system, with an electromotive cable drive, which is coupled to a cable drum for a traction cable, which is connected to a window carrier or rail slider guided without a rail or preferably slidingly along a guide rail. A first housing part with a number of through-openings for screw elements rotatably accommodates the cable drum. A second housing part assigned to the cable drive has a number of screw domes for receiving the screw elements corresponding to the number of through-openings of the first housing part.The second housing part of the cable drive is preferably a gear housing to which the electric motor is connected, for example by means of a screw fastening or screw connection as a mechanical interface.

[0011] The first housing part is also referred to below as the cable drive housing or the (cable) drum-side housing (part). The second housing part is also referred to below as the gearbox housing, the (motor) drive housing, or the drive- or motor-side housing (part).

[0012] The first housing part (cable drive housing) and the second housing part (motor drive or gear housing) form a screwable or screwed housing assembly. Both housing parts, in particular the second housing part on the motor side, are expediently made of plastic, for example as an injection-molded part. The first housing part on the cable drum side (cable drive housing) is arranged on a first plate side of the carrier plate. The second housing part on the motor side (motor drive housing) is arranged on a second plate side of the carrier plate opposite the first plate side. Preferably, the first housing part on the cable drum side is arranged on or at the wet room side corresponding to the second plate side, and the second housing part on the motor side is arranged on or at the dry room side of the carrier plate corresponding to the first plate side.

[0013] Suitably, the support plate has a number of through-openings which are aligned (on the one hand) with the through-openings of the first housing part accommodating the cable drum and (on the other hand) with the screw domes of the second housing part on the motor side.

[0014] The respective screw element has a screw head with a first tool holder, preferably serving or acting as the primary drive, and a threaded shaft with a shaft tip at the shaft end (facing away from the screw head). The thread can be metric or pre-formed in another way. The thread of the respective screw element is advantageously self-tapping. A second tool holder, preferably serving or acting as the secondary drive, is provided on or in the shaft tip, i.e., on the front side of the shaft end facing away from the screw head, or is incorporated into the shaft tip.

[0015] The second tool holder on the shaft tip of the respective screw element is suitably designed as an internal or external polygon or as an internal multi-round head, in particular as an internal or external hexagon or internal hexalobular head. A straight or Phillips slot as the second tool holder can also be sufficient if typically only a correspondingly low torque (loosening torque) is required to loosen the screw connection. Preferably, the second tool holder on the shaft tip of the respective screw element has an internal diameter of 3 mm to 5 mm, preferably (3.5 ± 0.5) mm, in particular 3.5 mm or 4 mm. In addition, the secondary drive can be incorporated into an additionally molded (cylindrical) shaft tip (without a thread), for example also with a thicker core diameter than that of the adjoining thread.

[0016] The second tool holder preferably serves or acts as a secondary drive in order to be able to actuate the screw element – ​​i.e., loosen or tighten – not only from the screw head, but also from the opposite shaft tip (using a tool). In other words, the respective screw element on the second plate side can be actuated, in particular loosened, to disassemble the motor-side second housing part screwed to the cable drum-side first housing part. As a result, the screw connection, in particular loosening the screw connection, of the housing assembly is always accessible from the dry room side of the door module or on the dry room side, in particular for disassembling the cable drive and / or for repairing the electric motor, for example its motor electronics.

[0017] In an advantageous embodiment, the first housing part has plug-in pins through which the through-openings for the screw elements pass. The screw domes of the second housing part expediently have (recessed) plug-in pockets for receiving the corresponding plug-in pins of the first housing part. This advantageously makes it possible to join the two housing parts (in time) before they are screwed together, in particular in a form-fitting manner, which facilitates assembly and increases error protection. Suitably, the first housing part has three through-openings and / or hollow plug-in pins arranged in the region of the corners of a triangle or positioned in a triangular arrangement. Analogously, the second housing part has screw domes positioned in the same triangular arrangement. For example, four such through-openings or screw domes can also be provided on the housing parts.

[0018] The thread of the screw element can extend over the entire threaded or screw shaft, from the screw head to the screw tip. With this design, it is advantageous if the clear width (inner diameter) of the through-hole of the first housing part on the cable drum side is at least slightly larger than the outer diameter of the threaded shaft, so that thread cutting or thread engagement in the through-hole is avoided and the two housing parts can be pulled together or against each other as intended and assembled into the housing assembly.

[0019] In a suitable embodiment, it is provided that the threaded shaft of the respective screw element has a first shaft section adjoining the screw head and having a first outer, core or shaft diameter, and a second shaft section opening into the shaft tip and having a second outer, core or screw diameter. The (outer) diameter of the first shaft section is preferably smaller than the (outer) diameter of the second shaft section. In this way, when the screw element is loosened, it can be held captively, for example in a form-fitting or clamping manner, in the associated through-opening or in the plug-in pin of the first housing part via the second tool holder. On the one hand, this prevents the respective screw(s) element from undesirably getting into the opening created after the vehicle door or the vehicle body has been completed when the element is loosened.Following the installation of the door module, for example, during disassembly or repair work on the drive or electric motor, the door falls into the inaccessible wet room. Following repairs or for the purpose of replacing the cable drive or its electric motor, the two housing parts can also be re-screwed from the dry room side without (completely) disassembling the door module.

[0020] On the other hand, when the two housing parts are (first) screwed together, the first shaft section with the comparatively small outer or shaft diameter enters the through hole or the plug-in pin of the first housing part (cable drive housing) during the screwing process, whereby no thread engagement takes place there and the two housing parts are pulled towards or against each other as intended.

[0021] The housing assembly, which is provided and configured in particular for a door module of a vehicle door of a motor vehicle, has a first and a second housing part, wherein the first housing part is provided and configured to receive a cable drum of a cable window lifter, while the second housing part is assigned to the cable drive constructed from an electric motor with a coupled gear. The first housing part has a number of, preferably three, triangularly arranged through openings, with each of which a screw dome of the second housing part is aligned. The screw domes serve to receive and screw together screw elements which are inserted over the through openings of the first housing part and have a threaded shaft and each have a tool holder at both shaft ends, in particular at a screw head and at a shaft or screw tip. The respective screw element is thus designed for its actuation, in particular for screwing orfor loosening the screw connection, accessible at both shaft ends, in particular from the rear of both the first housing part and the second housing part.

[0022] Exemplary embodiments of the invention are explained in more detail below with reference to a drawing. In the drawings: Fig. 1 is a schematic representation of a door module with a (vehicle) window lifter (cable window lifter) with a cable drive on or on a carrier plate and a guide rail with a (window) driver or rail glider with a driver function for the window pane that can be coupled to a window pane, Fig. 2a and 2b is an exploded view of the cable drive and the carrier plate of the door module as well as a housing assembly with the first housing part (cable drive housing) and with a second housing part (gear housing of the cable drive) with a view of a dry room or wet room side, Fig. 3 is a side view of a screw element with a tool holder on both ends (primary and secondary drive) for screwing the two housing parts together and for loosening a screw connection or screw connection, and Fig.4a and 4b schematically show in a sectional view the screw element screwed into or unscrewed from a screw dome of the second housing part via a through-opening and / or a hollow plug pin of the first housing part.

[0023] Corresponding parts and sizes are provided with the same reference numerals in all figures.

[0024] In the Fig. 1 a door module 1 is shown with a single-strand window lifter or a window lifter assembly mounted on a carrier plate or a functional carrier 2 as a supporting structure for installation in a vehicle door of a motor vehicle. The window lifter has a Figuren 2a and 2bThe cable drive 3 shown in FIG. 1 rotates a cable drum 4. The cable drum 4 is arranged in a first housing part 5a of a housing assembly 5, referred to below as the cable drive housing. A pull cable 6 of the window lifter is moved by means of the cable drum 4.

[0025] The cable drum 4 is wrapped by the traction cable 6, forming an incoming and an outgoing cable section 6a and 6b, respectively. The designation 6a, 6b of the incoming and outgoing cable section refers here to one of the two directions of rotation of the cable drum 4. To guide the traction cable 6, deflection elements 7, designed, for example, as cable or deflection pulleys, are provided, which are arranged at the ends of a rail contour of the support plate 2 or as a guide rail 8 mounted on the support plate 2. On this guide rail 8, a (window) driver 9 of the window lifter, which is connected or connectable to a window pane, or a rail slider with, for example, a clamping jaw-like driver contour 10 for the window pane (vehicle window) not shown, is arranged displaceably in the Z direction.

[0026] The information regarding the spatial directions is given in a coordinate system of the motor vehicle (vehicle coordinate system) with respect to the exemplary installation situation in a side door of the motor vehicle. The abscissa axis (X-axis) is oriented along the vehicle's longitudinal direction (direction of travel), the ordinate axis (Y-axis) along the vehicle's transverse direction, and the applicate axis (Z-axis) along the vehicle height. The Y-axis runs in Fig. 1 normal (perpendicular) to the drawing plane. Relative to the vehicle coordinate system, the support plate 2 lies in the XZ plane, and the rotation axis D ( Figu-ren 2a and 2b ) of the cable drum 4 is oriented orthogonally in the Y direction. The following specifications regarding the axial direction (axial) and radial direction (radial) refer to the rotational axis D of the cable drum 4, which is oriented in the Y direction.

[0027] The driver or rail slider 9 is connected to the traction cable 6, so that a movement of the traction cable 6 causes an adjustment of the rail slider (driver) 9 along the guide rail 8. Furthermore, the driver 9 or the rail slider holds the window pane by means of its driver contour 10, which is accordingly driven and moved when the rail slider or driver 9 is adjusted. The traction cable 6 is connected to the rail slider (driver) 9 via a spring element 11 arranged in the rail slider (driver) 9 in order to tension the traction cable 6 with a specific or predetermined cable tension.

[0028] In this exemplary embodiment, the window lifter is Bowden-less, i.e., it is a cable window lifter with an open cable system. However, a Bowden cable system can also be provided. The window lifter can also be designed with two parallel guide rails 8, which are mounted on the support plate 2 of the door module 1 or integrated into the support plate 2 and formed from the plastic material of the support plate. The cable drive 3 is preferably arranged between the guide rails or mounted on the support plate 2.

[0029] The Figuren 2a and 2b show in exploded views the cable drive 3 and - in detail or schematically reduced - the support plate 2 of the door module 1 as well as the housing assembly 5 with the first housing part 5a and with a second housing part 5b, which is also referred to below as the gear housing.

[0030] The Fig. 2a provides a view into the cable drive housing as the first housing part 5a as well as a first plate side of the support plate 2 facing a drying room T or located in this and the back of the second housing part 5b of the cable drive 3. The Fig. 2b provides a view into or onto the gear housing as the second housing part 5b as well as onto a second plate side of the carrier plate 2 facing or located in a wet room N and onto the back of the first housing part 5a as the cable drive housing.

[0031] In the Figuren 2a and 2bThe cable drum 4 can be seen, which (on the output side) sits on a bearing pin 12 of the cable drive housing as the first housing part 5a and is mounted there so as to be rotatable about the rotation axis D. The cable drum 4 is coupled (on the drive side) to a drive pin 13, which in turn is coupled to a gear 14 acting as a 90° deflection gear, preferably in the form of a worm gear. The gear 14, which is a component of the cable drive 3, is coupled to an electric motor 15, which is mounted on the gear housing as the second housing part 5b via a motor-gear interface 16. A plug connection 17 is used to supply current to the motor electronics or to control the electric motor 15 of the cable drive 3.

[0032] The first housing part (cable drive housing) 5a, which rotatably accommodates the cable drum 4, has a number of through-openings 18, positioned in a triangular arrangement in the exemplary embodiment, each for a screw element 19. The through-openings 18 correspond or are aligned with screw bosses 20 of the second housing part (gearbox housing) 5b, into which screw bosses 20 the screw elements 19 can be screwed. The first housing part (cable drive housing) 5a and the second housing part (motor drive or gearbox housing) 5b form the housing assembly 5, which can be screwed together using the screw elements 19. Both housing parts 5a, 5b, but in particular the second housing part 5b on the motor side, are made of plastic.

[0033] The first housing part 5a has plug-in pins 21 through which the through-openings 18 of the screw elements pass. The screw bosses 20 of the second housing part 5b have plug-in pockets 22, drawn in the longitudinal direction of the screw(s) element(s), for receiving the corresponding plug-in pins 21 of the first housing part 5a. This makes it possible to reliably join the two housing parts 5a, 5b, preferably with a positive fit, before screwing them together. The support plate 2 has through-openings 23, aligned with the through-openings 18 or with the hollow plug-in pins 21 of the first housing part 5a, which accommodates the cable drum 4, and with the screw bosses 20 or with the plug-in pockets 22 of the motor-side second housing part 5b, for passing through or inserting the screw elements 19.

[0034] Fig. 3 shows the screw element 19 with a self-tapping thread 24. With this thread shape, the screw element 19 automatically cuts into the respective screw dome 20 of the second, motor- or drive-side housing part 5b. The first housing part (cable drive housing) 5a and the second, motor-side housing part 5b are pulled against each other—with the support plate 2 interposed—and screwed together to form the housing assembly 5.

[0035] The screw element 19 has a screw head 19a with a first tool holder 25, also referred to below as the primary drive, and a threaded shaft 19b as well as a shaft tip 19c at the shaft end (facing away from the screw head). A second tool holder 26 is incorporated into the screw element 19 as a secondary drive at or in the shaft tip 19c or at the end face of the shaft end facing away from the screw head 19a. This second tool holder 26 at or in the shaft tip 19c of the screw element 19 is designed, for example, as a hexagon socket or a hexalobular socket (Torx), in particular with a diameter (inner diameter) of 3.5 mm or 4 mm.Via this second tool holder 26, the screw element 19 can be actuated from the dry room side T by means of a corresponding, compatible tool, so that the screw connection (screwing) of the two housing parts 5a and 5b of the housing assembly 5 of the cable drive 3 can always be loosened on or from the dry room side T.

[0036] The threaded shaft 19b of the screw element 19 or the shaft of the screw element 19 has a first shaft section 27a adjoining the screw head 19a and having a first outer diameter (core or shaft diameter) d 1 and a second shaft section 27b opening into the shaft tip 19c and having a second outer diameter (core or screw diameter) d 2. The (outer) diameter d 1 of the first shaft section 27a is smaller than or in comparison to the (outer) diameter d 2 of the second shaft section 27b, for example in that this first shaft section 27a is threadless and / or the diameter of the shaft core of this first shaft section 27a is smaller than that of the second shaft section 27b.

[0037] Fig. 4a shows a partial schematic or sectional view of the screw connection in one of the screw domes 20 of the drive- or motor-side second housing part 5b with the joining connection of the corresponding plug pin 21 of the cable drum-side first housing part (cable drive housing) 5a with or in the plug pocket 22 of the corresponding screw dome 20. The screw element 19 here has, for example, a metric (external) thread 24. In the screw dome 20, for example, a screw sleeve with an internal thread corresponding to the (external) thread 24 of the screw element 19 is then arranged.

[0038] In the screw connection, the first shaft section 27a with the reduced or tapered outer diameter d 1 of the screw element 19 is located in the area of ​​the through-opening 18 or in the plug-in pin 21 of the first, cable drum-side housing part 5a. Due to the fact that the clear width or the inner diameter of the through-opening 18 and / or the plug-in pin 21 is larger than the (outer) diameter of this first shaft section 27a of the screw element 19, no screw connection takes place in the area of ​​the through-opening 18 or the plug-in pin 21 of the first, cable drum-side housing part 5a, and the two housing parts 5a and 5b can be pulled or clamped against each other during the screw connection.

[0039] Fig. 4b illustrates the released state of the screw element 19, in that it is actuated via the secondary drive, i.e. the tool holder at the tip 19c, and is unscrewed from the screw dome 20. The screw element 19 remains with the shaft tip 19c in the through-opening 18 or in the plug-in pin 21 of the first housing part on the cable drum side (cable drive housing) 5a. For this purpose, the through-opening 18 or the plug-in pin 21 can have inwardly directed ribs or webs, for example as form-locking elements, in order to hold the screw element 19 at or in this position in the through-opening 18 or in the plug-in pin 21 of the first housing part on the cable drum side (cable drive housing) 5a, in particular in a form-locking and / or clamping or captive manner.In this way, following disassembly and / or repair of the drying room-side cable drive 3 or its electric motor 15, it can be reassembled by establishing the screw connection or screw connection of the two housing parts 5a and 5b on or from the drying room side T.

[0040] When loosening the screw element 19 via the second tool holder 26 at the shaft tip 19c of the screw element 19, the (positively locking) connection between the plug pin 21 and the screw dome 20 can also be released as the screw element 19 slides out of the screw dome 20. The thread 24 can also extend over both shaft sections 27a, 27b, i.e., over the entire threaded or screw shaft 19b.

[0041] The invention is not limited to the embodiments described above. Rather, other variants of the invention can be derived therefrom by those skilled in the art without departing from the subject matter of the invention defined in the appended claims. sen. List of reference symbols
