Description

[0001] Door drive device with locking element for a wall opening and at least two-part holder for fixing the locking element to an adjusting part of the door drive device.

[0002] Description

[0003] The proposed solution relates in particular to a door drive device for adjusting a vehicle door relative to a vehicle body.

[0004] A proposed door drive device comprises an adjusting element for power transmission between the vehicle door and the vehicle body and a drive motor coupled to the adjusting element via a gear assembly. As disclosed, for example, in DE 10 2019 211 932 A1, in such a door drive device the drive motor can be located, for instance, on the side of the vehicle door. The adjusting element is coupled to the vehicle body and also operatively connected to the drive motor in such a way that the adjusting element can be moved by the drive motor, thereby generating a force between the vehicle door and the vehicle body for the externally actuated adjustment of the vehicle door relative to the vehicle body. Alternatively, the drive motor can also be fixedly located on the side of the vehicle body and the adjusting element coupled to the vehicle door.In a door drive device known from DE 10 2019 211 932 A1, the gear assembly comprises at least one guide element, for example in the form of a guide rail, and a sliding element coupled to the adjusting part, which is guided along the guide element along an adjustment direction and is adjustable by the drive motor.

[0005] If the door drive unit, including the drive motor and gearbox assembly, is mounted on the vehicle door, the adjusting element protrudes through an opening in a section of the door wall when the door drive unit is properly installed. The end of the adjusting element protruding from the opening is then intended for connection to the vehicle body and is typically hinged to the body, for example, via a pivot pin. It may be desirable to close the opening in the door wall as completely as possible, at least in a certain adjustment position of the adjusting element, and thus of the vehicle door. This is intended, for example, to prevent drafts between the door interior and the sill area of ​​the vehicle door, and in turn, to prevent dirt from the door interior (e.g.,(from a window channel for a window pane of the vehicle door) into the sill area. Alternatively or additionally, the wall opening can be sealed to prevent dirt and / or moisture from reaching the drive motor and the transmission assembly.

[0006] Against this background, the proposed solution is based on the task of providing a door drive device that is improved in this respect.

[0007] In a proposed door drive device for adjusting a vehicle door relative to a vehicle body, a closing element is arranged at the first end of an externally operated adjusting element. This closing element is designed to at least partially close an opening in a wall section of the vehicle door in at least one adjustment position relative to the vehicle body. The adjusting element is coupled to a drive motor of the door drive device via a transmission assembly and is intended for power transmission between the vehicle door and the vehicle body. The adjusting element extends between its first end and a second end, the second of which is connected, for example, to a sliding element of the transmission assembly.The first end of the adjusting element can be designed for coupling to the vehicle body or the vehicle door, depending on whether the drive motor and gearbox assembly of the door drive device are intended for mounting on the vehicle door or the vehicle body. In the properly installed state of the door drive device, the adjusting element can then be adjusted relative to a section of the vehicle door wall or relative to a section of the vehicle body wall. The locking element allows the opening in the respective wall section to be at least partially or completely closed, for example, when the vehicle door is in a fully closed position.

[0008] The sealing element prevents dirt and / or moisture from entering the installation space housing the drive motor and gearbox assembly, and thus from reaching the door drive device, through the wall opening, especially when the vehicle door is (fully) closed and the vehicle is in motion. It is also possible that, even without the sealing element, the wall opening in this section may not allow unimpeded access for dirt into the installation space housing the drive motor and gearbox assembly (for example, at the vehicle door or vehicle body).However, the locking element offers at least in one adjustment position additional protection against dirt, especially dust and / or moisture, entering the drive motor and gearbox assembly through the wall opening, particularly during travel of a vehicle equipped with the door drive device and the resulting drafts.

[0009] To facilitate the mounting of the locking element to the first end of the adjusting part, a holder consisting of at least two parts and attached to the first end of the adjusting part is provided. The locking element is held on the adjusting part by this holder. This allows – at least when the holder and locking element are manufactured separately – for the connection of the locking element to be provided exclusively on the holder; an independent fastening option on the adjusting part is not required. In one variant, the locking element, or at least sections thereof, can also be formed on the holder.

[0010] To close the wall opening in precisely one specific adjustment position, corresponding, for example, to the closed position of the vehicle door, the locking element does not need to be adjustable relative to the locking part. The locking element can therefore be held immovably on the adjustment part by means of the holder, which has at least two parts. The locking element can, in turn, be designed to rest against an edge of the wall section that borders the wall opening. In particular, the locking element can be designed to create a tight seal against the edge bordering the wall opening and, especially, to completely cover the wall opening.The locking element thus completely covers the wall opening over the circumference of the wall opening when, in an adjustment position of the adjusting part and thus a corresponding adjustment position of the vehicle door, the locking element provided at the first end is sufficiently close to the wall section.

[0011] The locking element can, in principle, include a through-opening through which a section of the adjusting part protrudes.

[0012] In one embodiment, a fastening element is provided on the holder, to which the locking element is attached. In particular, the fastening element can be designed and intended for tool-free attachment of the locking element to the holder.

[0013] For example, the locking element is attached to the fastening element via a positive fit. This positive fit can be achieved, for instance, by the edge of a through-hole provided in the locking element for the adjusting part engaging with a fastening area of ​​the fastening element. In a further embodiment, the edge of the through-hole fully engages with the fastening area of ​​the fastening element, preventing dirt and / or moisture from penetrating through the through-hole of the locking element.

[0014] In one embodiment, the fastening element of the holder is hollow and, in particular, hollow cylindrical, so that a section of the adjusting part extends through a through-opening of the fastening element or through the through-opening of the fastening element.

[0015] In one embodiment, the holder for the at least two-part version comprises a first holder part and a second holder part. The first and second holder parts are fixed to each other and together define a receiving space in which the first end of the adjustment element is accommodated. The at least two-part design of the holder, with its first and second holder parts, simplifies the mounting of the holder to the adjustment element. The two holder parts can thus be mounted to the adjustment element sequentially and fixed together.

[0016] For example, it is envisaged that the first and second holder parts are fixed to each other at a parting plane that runs parallel or perpendicular to a longitudinal axis along which the adjusting part extends from its first end to its second end. Thus, if, for example, the adjusting part extends along an X-axis in a Cartesian coordinate system, and the parting plane runs parallel to the longitudinal axis, the parting plane can lie in the XY or XZ plane. The first and second holder parts would then be attached to the first end of the adjusting part along a Y-axis or Z-axis when the holder is mounted to the adjusting part.

[0017] Alternatively or additionally, the first and second holder parts can be connected via a connecting section of the holder, by which the first holder part is pivotably held on the second holder part for mounting the holder to the adjusting part. In this way, for example, the second holder part can be attached to the first end of the adjusting part, in particular by clipping it on, before the second holder part is then moved towards the first end by pivoting relative to the first holder part and positioned there.

[0018] Connecting the first and second holder parts via a connecting section before mounting them to the adjustment part can also simplify the manufacturing of the holder parts and thus the holder itself. This allows, for example, the first and second holder parts to be manufactured from a single plastic material using a single tool.

[0019] In a further development, the connecting section defines at least one pivot axis around which the first mounting part, used to attach the holder to the adjusting part, can pivot relative to the second mounting part. This pivot axis runs perpendicular to the longitudinal axis along which the adjusting part extends from its first end to its second end. During assembly, the second mounting part can therefore be positioned at the first end of the adjusting part. By pivoting about this at least one pivot axis, the first mounting part is then also attached to the first end and fixed to the second mounting part.

[0020] For example, the connecting section can also define two pivot axes around which the first mounting part, used to attach the holder to the adjustment part, can pivot relative to the second mounting part, and which each run perpendicular to the longitudinal axis. This specifically implies that the two pivot axes defined by the connecting section are parallel to each other. Alternatively or additionally, the two pivot axes defined by the connecting section can enable two successive pivoting movements of the first mounting part relative to the second mounting part, which is already attached to the adjustment part, during assembly.The second holder part can therefore be attached to the first end of the adjusting part by performing two pivoting movements about two different pivot axes and fixed to the second holder part in a working position, so that the holder is in a properly assembled state at the first end of the adjusting part.

[0021] The connecting section for the connection between the first and second holder parts can, for example, be designed with at least one film hinge. One hinge axis of the film hinge then forms a pivot axis as mentioned above.

[0022] To further simplify assembly, the first and second holder parts can be clipped together. Consequently, at least one clip connection (also known as a snap connection) is provided, so that when mounting the holder, the first and second holder parts only need to be pressed together with sufficient force, and one or more locking elements of one holder part will engage positively with the other holder part.

[0023] If the first and second holder parts are intended for a holder consisting of at least two parts, the fastening element sections of the first holder part and the second holder part can also jointly define the fastening element of the holder. In particular, the fastening element can be formed by a first fastening element section of the first holder part and a second fastening element section of the second holder part.

[0024] In one embodiment, the bracket has a through-opening that aligns with a through-opening, for example in the form of a (connecting) eye, at the first end of the adjusting element. A joint element extending through the through-opening on the bracket and the through-opening at the first end is then provided, for example, for a flexible connection of the adjusting element to the vehicle body (if the drive motor and the transmission assembly are to be located on the vehicle door). Consequently, a flexible connection of the adjusting element to the vehicle body can be provided via the joint element if the drive motor and the transmission assembly of the door drive device are to be located on the vehicle door.Alternatively, the joint element can be designed for a flexible connection between the adjusting part and the vehicle door if the drive motor and the gearbox assembly of the door drive device are to be located on the vehicle body. For example, the joint element is designed with a pivot pin that passes through the openings on the bracket and the first end of the adjusting part.

[0025] The through-opening of the holder can be formed on a base body of the holder, which comprises a first base body section of the first holder part and a second base body section of the second holder part. The base body containing the through-opening is thus formed here by the first and second base body sections of the first and second holder parts fixed together. For example, part of the later through-opening on the fully assembled holder can be formed on a base body section of each holder part.

[0026] Alternatively or additionally, the through-opening of the holder is formed on a base body from which the fastening element projects towards the second end of the adjusting part. In a properly assembled vehicle door assembly comprising the door drive device, the holder therefore has a base body with a through-opening for the (preferably articulated) connection of the first end to the vehicle body or the vehicle door, as well as a fastening element projecting from the base body to which the locking element is attached.

[0027] Part of the proposed solution is a vehicle door assembly which, in addition to a vehicle door defining a door interior, includes a variant of a proposed door drive device. The drive motor and the gearbox assembly of the door drive device are located at least partially within the door interior or within an interior space on the vehicle body. To enable coupling with the vehicle body or the vehicle door, the adjusting element extends through a wall opening in a wall section on the vehicle door side or the body side, which borders the door interior or the interior space on the vehicle body, in order to adjust the adjusting element relative to the wall section when driven by the drive motor.

[0028] Furthermore, a method for assembling a door drive device is proposed, which is intended for adjusting a vehicle door relative to a vehicle body and which comprises an adjusting element for power transmission between the vehicle door and the vehicle body, a drive motor, and a transmission assembly coupling the drive motor to the adjusting element. Within the framework of the proposed method, a holder with at least two parts is attached to a first end of the adjusting element, and a closing element is fixed to the holder. This closing element is designed to at least partially close a wall opening in a wall section (of the vehicle door or the vehicle body) in at least one adjustment position of the vehicle door relative to the vehicle body. This opening defines an interior space in the vehicle door or the vehicle body in which the drive motor and the transmission assembly are arranged.

[0029] To simplify the attachment of the holder to the adjustment part, the holder can comprise a first and a second holder part that are clipped together. The first and second holder parts are thus fixed to each other by at least one clip connection (snap connection) and secured to the first end of the adjustment part.

[0030] Alternatively or additionally, the holder can comprise a first holder part and a second holder part, which are connected to each other via a connecting section prior to assembly onto the adjusting part. During assembly, the first holder part is then pivoted about at least one pivot axis defined by the connecting section relative to the second holder part already attached to the adjusting part, in order to attach the first holder part to the adjusting part and fix it to the second holder part. The at least one pivot axis runs, for example, perpendicular to a longitudinal axis along which the adjusting part extends from its first end to its second end.

[0031] In particular, an embodiment of a proposed method can be used to assemble an embodiment of a proposed door drive device. The advantages and features described above and below for embodiments of a proposed door drive device therefore also apply to embodiments of a proposed method, and vice versa. The accompanying figures illustrate possible embodiments of the proposed solution.

[0046] Figure 8B shows the door drive device of Figure 8A in top view;

[0048] Figure 10 shows a partially cutaway view of a door drive device according to the proposed solution;

[0049] Figure 7 shows a schematic view of a vehicle 1 with a vehicle body 10 and a vehicle door 11 arranged on the vehicle body 10 by means of a door hinge 111, which can be pivoted along an opening direction O relative to the vehicle body 10 in order to open or close a door opening.

[0050] A door drive device 2 acts between the vehicle body 10 and the vehicle door 11. This device includes an adjusting element in the form of a push rod 21, which serves to adjust the vehicle door 11 relative to the vehicle body 10. The push rod 21 is pivotally mounted at a first end 210 about a joint 20 on the vehicle body 10, for example, on the A-pillar of the vehicle 11, and moves when the vehicle door 11 pivots relative to the vehicle door 11. For this purpose, the adjusting element 21 projects with a second end 211 into a door cavity 110 of the vehicle door 11 and moves within this door cavity 110 when the vehicle door 11 is adjusted.

[0051] Figures 8A, 8B, 9A, 9B, and 10 show views of an embodiment of the door drive device 2, which serves to adjust an adjusting element, such as the push rod 21, and thereby to move the vehicle door 11 relative to the vehicle body 10. Figures 8A, 8B, 9A, and 9B show the door drive device 2 in side and top views with the push rod 21 in different end positions, while Figure 10 shows a partially cutaway view of the door drive device 2 in the extended position of the push rod 21, as shown in Figures 9A and 9B. Figure 10 thus shows, in particular, a sliding element 26 of a gear assembly 23 of the door drive device 2.

[0052] This sliding element 26 is slidably mounted on a guide element of the door drive device 2 in the form of a guide rail 27. The guide rail 27 is housed within a gearbox housing 24 of the door drive device 2. The sliding element 26 rests slidably against the guide rail 27 such that it can be moved along the guide rail 27 in an adjustment direction V. In this case, the guide rail 27 has a C-shape in cross-section transverse to the adjustment direction V, formed by a base and legs extending laterally from the base and angled towards the base, the edges of which are bent towards each other. The sliding element 26 is guided in the guide rail 27 such that it is held between the legs and fully enclosed by the base, the legs, and the bent edges of the guide rail 27.

[0053] In the illustrated embodiment, the guide rail 27 is formed as a bent metal sheet component and is rigidly connected to the gearbox housing 24 via an adapter part in the form of a mounting plate 242 and sections abutting the gearbox housing 24. The mounting plate 242 is connected to the gearbox housing 24 via fastening elements 243 in the form of screws and can be fixed to a structural section of the vehicle door 11, for example to an inner door panel section, via fastening elements 244 in the form of screws, so that the door drive device 2 is fixed in the vehicle door 11.

[0054] To adjust the push rod 21 coupled to the sliding element 26, the gear assembly 23 has, in particular, a drive spindle 25 which meshes with a spindle nut of the sliding element 26. This spindle nut is formed on a spindle nut section of the sliding element 26. In Figures 8A to 9B, this spindle nut section of the sliding element and the guide rail 27 are covered externally by a cover element 241 of the gear housing 24.

[0055] The push rod 21 is pivotally coupled at its first end 210 to a joint 20 via a pivot pin 200 about a pivot axis. The joint 20 is rigidly connected to the vehicle body 10, as shown schematically in Fig. 7. At its second end 211, which is located away from the first end 210, the push rod 21 is pivotally coupled to the sliding element 26. Due to the configuration of the door drive device 2, the push rod 21 can have a relatively simple geometry and, for example, runs almost straight between the respective pivoted ends 210 and 211. By adjusting the sliding element 26, driven by the drive motor 22, the second end 211 of the push rod 21 can be moved on the guide rail 27, so that the push rod 21 moves between a first, retracted position (Fig. 8A and 8B) and a second, extended position (Fig.9A and 9B) can be adjusted to move the vehicle door 11 relative to the vehicle body 10 and to adjust between a closed position (corresponding to the retracted position of the push rod 21) and an open position (corresponding to an extended position of the push rod 21).

[0056] In the first, retracted position, the sliding element 26 is removed from the gearbox housing 24 and is approaching an end of the guide rail 27 that is furthest from the mounting plate 242. In the second, extended position, the sliding element 26 is moved towards the gearbox housing 24, so that the spindle nut section (which projects upwards on the sliding element 26) is approaching the gearbox 23 and the push rod 21 is moved with its second end 211 in the adjustment direction V towards the mounting plate 242.

[0057] In the second position, the sliding element 26 dips with a base section under the gearbox 23, as the sliding element 26, viewed along the adjustment direction V, comes into axial overlap with the gearbox housing 24 and the gearbox 23 mounted thereon, as can be seen in Figure 10. This enables a space-efficient design of the drive device 2, with a comparatively large stroke of the push rod 21 along the adjustment direction V and a low overall height transverse to the adjustment direction V, in particular vertically along the pivot axis of the joint 20.

[0058] Figure 1A shows the first end 210 of the push rod 21, which is to be connected to the vehicle body 10, with a view of a wall section 112 of the vehicle door 11. A wall opening 1120 is formed in the wall section 112 of the vehicle door 11, through which the push rod 21 extends from the interior of the door 110 to the outside. To close this wall opening 1120, and in particular to seal it when the vehicle door 11 is in a closed position and is fully closed, a flat sealing element 3 is provided. When the vehicle door 11 is in its closed position, the sealing element 3, as shown in Figure 1B, rests completely against an edge surrounding the wall opening 1120, thus preventing the ingress of dirt, especially dust and moisture, through the wall opening 1120 into the interior of the door 110.The sealing element 3, which closes the wall opening 1120, prevents dirt from entering the drive motor 22 and the gearbox assembly 23 located in the door interior 110 when the vehicle door 11 is closed and the vehicle 1 is moving. The sealing element 3 thus forms a so-called draft seal for the wall opening 1120, preventing dust from entering the door interior 110 and consequently the drive motor 22 and the gearbox assembly 23 due to drafts through the wall opening 1120, which occur particularly when the vehicle 1 is moving.

[0059] To facilitate the attachment of the locking element 3 to the first end 210 of the push rod 21, a holder 4 consisting of at least two parts is provided. This holder 4 is designed as a plastic component and clipped onto the first end 210.

[0060] As can be seen particularly from the perspective view in Figure 2, the holder 2 has a base body 41 with a through-opening 410. The ends of the through-opening 410 are aligned with a through-opening in the form of a (connecting) eye for the pivot pin 200 provided at the first end 210 of the push rod 21. The pivot pin 200 can thus pass through the base body 41 and the through-opening of the push rod 21 at the first end 210 of the push rod 21.

[0061] A fastening element 42 projects radially outwards from the base body 41, relative to a central axis of the through-opening 410. The fastening section 42 serves to secure the locking element 3 to the holder 4. For this purpose, the fastening element 42 forms a fastening area 421, which is designed as a recess between two holder edges 420.1 and 420.2 that are opposed to each other (axially relative to a longitudinal axis L of the push rod 21). The locking element 3 can be slid onto the fastening element 42 through a through-opening 30 over the outermost holder edge 420.1. For this purpose, the holder edge 420.1 can, for example, be at least partially elastic.

[0062] As the closure element 3 is pushed further onto the fastening element 42 towards the passage opening 410, its edge, which borders the passage opening 30, can engage positively in the recessed fastening areas 420, so that the edge bordering the passage opening 30 is received between the two holder edges 420.1 and 420.2. This secures the closure element 3 immovably to the fastening element 421 of the holder 4.

[0063] In order to secure the holder 4 to the first end 210 of the push rod 21, the holder 4 is designed in at least two parts, namely two holder parts 4A and 4B. These holder parts 4A and 4B are fixed to one another in the state shown in Figures 1A, 1B and 2, in this case by one or more clip connections or snap connections.

[0064] In one embodiment illustrated in Figures 3, 4A, and 4B, the two holder parts 4A and 4B, when connected, lie against each other along a dividing plane that runs parallel to a longitudinal axis L along which the push rod 21 extends. To further simplify assembly, the two holder parts 4A and 4B are also connected to each other on their outer sides by a band-shaped connecting section 40. This connecting section 40 is integrally formed with the two holder parts 4A and 4B and is hinged to each holder part 4A and 4B by means of film hinges.

[0065] The first holder part 4A, together with a first base body section 41A, forms one half of the base body 41 and, together with a fastening element section 42A formed on the base body section 41A, forms one half of the fastening element 42 of the holder 4. The second holder part 4B, in turn, together with a second base body section 41B, forms the second half of the base body 41 and, together with a second fastening element section 42B, forms the second half of the fastening element 42. Furthermore, an inner channel 410A or 41OB is formed on each of the base body sections 41A and 42B, which is interrupted in a central region by a receiving space for the eye-equipped first end 210 of the push rod 21. When the first and second holder parts 4A and 4B are assembled, the channels 410A and 41OB together define the through-opening 410 of the holder 4.

[0066] As illustrated in particular by Figure 3, the first and second holder parts 4A and 4B can be manufactured together in a single tool from plastic material and mounted to the push rod 21 in a connected state via the connecting section 40. First, one of the holder parts, here the second holder part 4B, is attached to the first end 210, for example, by simply inserting it. In the embodiment shown in Figures 3, 4A, and 4B, the second holder part 4B is inserted laterally onto the first end 210 along a spatial direction perpendicular to the longitudinal axis L.

[0067] Via the film hinges and the articulated connection between the second holder part 4B, the connecting section 40, and the first holder part 4A, the first holder part 4A can also be attached to the first end 210 by performing a pivoting movement relative to the second holder part 4B, which is already mounted on the push rod 21. In this process, the first holder part 4A, together with the band-shaped connecting section 40, can first be pivoted about a first pivot axis S1 relative to the second holder part 4B. This first pivot axis S1 is defined by a first film hinge between the connecting section 40 and the second holder part 4B. Subsequently, the first holder part 4A can be pivoted about a second pivot axis S2 relative to the connecting section 40 and the second holder part 4B, the second pivot axis S2 being defined by a second film hinge between the connecting section 40 and the first holder part 4B.

[0068] In the embodiment shown in Figures 5 and 6, the two holder parts 4A and 4B are also connected to each other via a band-shaped connecting section 40 and film hinges. The first and second holder parts 4A and 4B can again be pivoted relative to each other about two parallel pivot axes S1 and S2 via two film hinges. In contrast to the embodiment shown in Figures 3, 4A, and 4B, a dividing plane between the two holder parts 4A and 4B in Figures 5 and 6 runs parallel to the longitudinal axis L of the push rod 21, but perpendicular to the dividing plane of the embodiment shown in Figures 3, 4A, and 4B. The pivot axes S1 and S2 of the embodiment shown in Figures 5 and 6 are therefore also perpendicular to the pivot axes S1 and S2 of the embodiment shown in Figures 3, 4A, and 4B.For example, one of the holder parts 4A, 4B can be attached to the first end 210 from below or from above, and the other holder part is folded around the pivot axes S1 and S2 onto the first end 210.

[0069] In the embodiments shown in Figures 3, 4A, and 4B on the one hand, and Figures 5 and 6 on the other, a dividing plane between the two support parts 4A and 4B runs parallel to the longitudinal axis L, but rotated 90° relative to each other. Similarly, the first and second pivot axes S1 and S2, which run parallel to each other, are oriented perpendicular to the longitudinal axis L, but are rotated 90° relative to each other in both embodiments. Thus, if, for example, the longitudinal axis L extends along an X-axis in a Cartesian coordinate system, the dividing plane in the embodiment shown in Figures 3 to 4B lies in the XZ plane, while in the embodiment shown in Figures 5 and 6, the dividing plane lies in the XY plane. The first and second holder parts 4A, 4B are therefore attached to the first end 210 along a Y-axis (Figures 3 to 4B) or along a Z-axis (Figures 5 and 6) in order to mount the holder 4 to the push rod 21.

[0070] In contrast to the illustrations in Figures 3 to 4B and Figures 5 and 6, a separating plane between the two holder parts 4A and 4B can also be provided perpendicular to the longitudinal axis L (in the YZ plane).

[0071] The door drive device 2 can be installed in a vehicle door 11 with the drive motor 22 facing upwards, as illustrated in Figures 8A to 10, or alternatively with the drive motor 22 facing downwards. The drive motor 22 can also be arranged at an end of the guide rail opposite the end of the guide rail where the adjusting element 21 exits the guide rail. This allows the drive device 2 to be used universally on different door models of different vehicles.

[0072] The underlying idea of ​​the invention is not limited to the exemplary embodiments described above, but can also be realized in completely different embodiments.

[0073] A door drive device of the type described can be used in particular on a vehicle side door as well as on a tailgate or any other vehicle opening.
