[0001] Assembly for manufacturing a door drive device for adjusting a vehicle door relative to a vehicle body

[0002] Description

[0003] The invention relates to an assembly for manufacturing a door drive device for adjusting a vehicle door relative to a vehicle body according to the preamble of claim 1, a door drive device for adjusting a vehicle door relative to a vehicle body, a vehicle assembly and a method for manufacturing a door drive device.

[0004] Such an assembly for manufacturing a door drive device comprises an adjusting element for power transmission between the vehicle door and the vehicle body, a drive motor, a gearbox assembly for coupling the drive motor with the adjusting element, and a gearbox housing.

[0005] A door drive device described in WO 2021 / 023893 A1 has an adjusting element in the form of a catch strap, which is articulated to a vehicle body and can be adjusted via a door drive device on the side of the vehicle door in order to move the vehicle door relative to the vehicle body. The door drive device has a gear assembly in the form of a spindle drive, which has a rotatable spindle that engages with a spindle nut section of a sliding element in such a way that by rotating the spindle, the sliding element can be moved longitudinally along a guide rail in order to move the adjusting element to adjust the vehicle door.

[0006] In such a door drive device, the drive motor can, for example, be located on the side of the vehicle door. The adjusting element is coupled to the vehicle body in its operating position and is also operatively connected to the drive motor in such a way that the adjusting element is moved by the drive motor, thereby generating a force between the vehicle door and the vehicle body for the electromechanical adjustment of the vehicle door relative to the vehicle body. Because, for example, the installation space in the vehicle door is limited, such a door drive device should be designed to be space-saving, so that it occupies only a comparatively small installation space, for example, in a vehicle door.

[0007] Using such a door drive device, for example, automatic electromechanical adjustment of the vehicle door can be enabled in automatic operation, or motor-assisted manual adjustment of the vehicle door can be enabled in servo operation.

[0008] To manufacture a door drive device, the components of the door drive device must be joined together. For example, the motor housing, made of metal, must be connected to the gearbox housing in such a way that a drive element mounted on a motor shaft is operatively connected to an associated mounting component of the gearbox assembly, thus creating a power transmission path from the drive motor, via the gearbox assembly, to the adjustment element.

[0009] Typically, the motor housing is bolted to the gearbox housing, for example. However, this can be complex to assemble and also requires separate components for creating the bolted connection. Furthermore, it can impose limitations on the arrangement and orientation of the drive motor relative to the gearbox assembly.

[0010] The object of the present invention is to provide an assembly for manufacturing a door drive device, a door drive device, a vehicle assembly and a method for manufacturing a door drive device, which enable simple assembly and thus cost-effective manufacturing of the door drive device.

[0011] This problem is solved by an object having the features of claim 1.

[0012] Accordingly, the assembly includes a connecting device designed to connect the gearbox housing and the motor housing. The connecting device has at least one engagement section formed on one of the gearbox housing and the motor housing, and at least one engagement element formed on the other of the gearbox housing and the motor housing, which can be brought into engagement with each other to establish a connection between the gearbox housing and the motor housing.

[0013] The gearbox housing, which at least partially encloses the gearbox assembly, is to be connected to the motor housing of the drive motor to manufacture the door drive device. To facilitate simple assembly and manufacturing of the door drive device, the connecting device used to join the gearbox housing to the motor housing is designed with one or more engagement sections and one or more engagement elements, which are arranged on the gearbox housing on one side and on the motor housing on the other, thus enabling a connection of the gearbox housing to the drive motor without the need for additional components.

[0014] In particular, additional fastening elements such as screws or rivets, which would otherwise need to be attached as separate components to the gearbox housing or the motor housing to create a connection between the gearbox housing and the motor housing, can be omitted. Instead, one or more engagement sections and one or more engagement elements are formed on the motor housing and the gearbox housing and can be engaged with each other to create a connection between the gearbox housing and the motor housing during the assembly of the door drive device.

[0015] The at least one engagement section and the at least one engagement element can preferably be brought into engagement with each other in such a way that a positive-locking or force-locking connection is created between the gearbox housing and the motor housing. The gearbox housing and the motor housing can thus be positively or force-locked to each other via the connecting device. Because the at least one engagement section is formed on the gearbox housing or the motor housing, the engagement section is fixedly arranged on the gearbox housing or the motor housing. Likewise, the at least one engagement element is fixedly arranged on the motor housing or the gearbox housing because it is formed on the other of the gearbox housing and the motor housing, respectively. The gearbox housing and the motor housing can each be designed as a single piece or as multiple pieces.In any case, the engagement section and the engagement element are firmly formed on an associated housing part of the gearbox housing or the engine housing.

[0016] In one embodiment, the at least one engagement section is integrally formed on one of the gearbox housings and the motor housing. Additionally or alternatively, the at least one engagement element is integrally formed on the other of the gearbox housings and the motor housings. The gearbox housing and the motor housing can, for example, each be integrally formed in one piece, with the at least one engagement section and the at least one engagement element being integrally and integrally formed on the respective associated housing part.

[0017] In one embodiment, the connecting device permanently joins the gearbox housing and the motor housing in an assembly position. For mounting the door drive unit, the gearbox housing and the motor housing can be placed against each other and connected via the connecting device. Once the connection is established by the engagement of at least one engagement element with at least one engagement section, the connection between the gearbox housing and the motor housing is permanent.

[0018] In this context, an indissoluble connection means that the connection between the gearbox housing and the motor housing cannot be detached without destruction, i.e., in particular not without destroying components of the connecting device, i.e., at least one engagement section and / or at least one engagement element.

[0019] In one embodiment, the at least one engagement element has a fixed initial shape in a pre-assembly position and is plastically deformable to create the connection between the gearbox housing and the motor housing. The gearbox housing and the motor housing can be joined together to assemble the door drive device. The at least one engagement element is initially in its undeformed initial shape, which allows the gearbox housing and the motor housing to be joined together. Once the gearbox housing and the motor housing have been joined together, the at least one engagement element can be plastically deformed to engage with the at least one engagement section, thus creating a permanent connection between the motor housing and the gearbox housing.Due to the plastic deformation, the engagement of at least one engagement element with at least one engagement section cannot be easily resolved, but can generally only be eliminated by destroying the connecting device.

[0020] Such plastic deformation of at least one engagement element can be achieved, for example, by cold forming or hot forming. For instance, an engagement element on the motor housing, which may be made of metal, can be deformed by cold forming. In contrast, the gearbox housing may be made of plastic, and an engagement element of the gearbox housing may be formed, for example, by hot forming, thus partially melting the at least one engagement element.

[0021] In one embodiment, at least one engagement element and at least one engagement section are configured to create a bayonet connection for connecting the gearbox housing and the motor housing. In such an embodiment, the connection between the gearbox housing and the motor housing is fundamentally detachable by releasing the bayonet connection. Within such a bayonet connection, the at least one engagement element and the at least one engagement section can be brought into engagement by placing the gearbox housing and the motor housing against each other, and then the bayonet connection is established by rotating the gearbox housing and the motor housing relative to each other through a certain angle.

[0022] In one embodiment, the drive motor has a motor shaft that can be rotated about a longitudinal axis. A drive element, such as a drive worm, can be arranged on the motor shaft, engaging with a drive wheel of the gearbox assembly when the door drive device is installed and thus in an operational state. The motor housing can, for example, be cylindrical with respect to its longitudinal axis. For instance, the motor housing is designed as a cylindrical metal part, particularly a tubular one.

[0023] In one embodiment, the connecting device has an attachment section arranged on the gearbox housing, to which the motor housing can be attached along its longitudinal axis. The attachment section can, for example, be cylindrical with respect to its longitudinal axis. The attachment section thus particularly enables the attachment of a cylindrical motor housing. To connect the gearbox housing to the motor housing, the gearbox housing and the motor housing can, for example, be joined together along their longitudinal axis such that the motor housing, with its attachment section, comes into contact with the gearbox housing.

[0024] In one embodiment, at least one engagement element or at least one engagement section is formed integrally with the attachment section. At least one engagement element and / or at least one engagement section is thus arranged on the attachment section, so that a connection to the motor housing can be established via the attachment section.

[0025] In one embodiment, the connecting device has a plurality of engagement sections arranged one after the other around the longitudinal axis and / or a plurality of engagement elements arranged one after the other around the longitudinal axis. For example, several engagement elements can be arranged on the gearbox housing or the motor housing, while one or more engagement sections are arranged on the other of the gearbox housing and the motor housing. In another embodiment, one or more engagement elements are arranged on the gearbox housing or the motor housing, and a plurality of engagement sections are arranged on the other of the gearbox housing and the motor housing. For example, several engagement elements are arranged on one of the gearbox housing and the motor housing, and in addition, several engagement sections are formed on the other of the gearbox housing and the motor housing. The multiple engagement elements orThe multiple engagement sections can be arranged at regular intervals along a circumferential direction around the longitudinal axis. Such an arrangement of multiple engagement elements and / or multiple engagement sections allows, for example, the gearbox housing and the motor housing to be positioned and connected in a multitude of angled positions relative to each other around the longitudinal axis. The motor housing can thus be aligned with the gearbox housing by selecting a desired angular position, thereby taking installation space constraints into account to create a space-efficient arrangement of the door drive device.

[0026] By selecting the angular position of the motor housing relative to the gearbox housing, in particular a connector exit direction, along which a connector for the electrical supply of the drive motor extends, can be freely chosen within predefined limits.

[0027] In one embodiment, at least one engagement element is formed by a plastically deformable tab on the motor housing. This engagement element can, for example, be freely stamped as a tab on the motor housing, which may be made of metal. One or more tabs can be formed on the motor housing to engage with one or more associated engagement sections on the transmission housing through plastic deformation, for example, by cold forming, such as bending.

[0028] If at least one engagement element is formed by a plastically deformable tab on the motor housing, the at least one engagement section can be formed, for example, by a recess on the gearbox housing. Such a recess can be formed as a depression or a (continuous) opening on the gearbox housing. In the undeformed state of the engagement element, the gearbox housing and the motor housing can be joined together for assembly. Once the gearbox housing and the motor housing have been joined together, the at least one engagement element can be plastically deformed so that it engages with the at least one engagement section, i.e., the tab extends into the recess and thus creates a positive-locking or force-locking connection between the gearbox housing and the motor housing.

[0029] In one embodiment, at least one engagement element is formed by a radially projecting projection element on the gearbox housing. Such a radially projecting projection element can, for example, be formed on the cylindrical attachment section and project radially outwards from the cylindrical attachment section. A bayonet connection between the gearbox housing and the motor housing can be established, for example, by engaging a bayonet opening formed on the motor housing via such a radial projection element. The bayonet opening forms the at least one engagement section on the motor housing and is designed such that the radial projection element can be inserted into the bayonet opening and locked relative to each other by rotating the gearbox housing and the motor housing about the longitudinal axis of the drive motor, thus establishing a bayonet connection between the gearbox housing and the motor housing.

[0030] In one embodiment, the at least one engagement element is formed by at least one plastically deformable element on the gearbox housing. Such a plastically deformable element can, for example, be formed by a circumferential edge section of the attachment section. In another embodiment, the at least one plastically deformable element can be formed by a claw element projecting axially along the longitudinal axis from the attachment section. In this case, the at least one engagement section can, for example, be formed by a radially projecting collar or a groove on the motor housing. By plastically deforming the at least one engagement element, an engagement can be established between the at least one engagement element and the at least one engagement section, thus creating a positive-locking or force-locking connection between the gearbox housing and the motor housing.

[0031] The collar or groove can, for example, be formed rotationally symmetrically, i.e., circumferentially around the longitudinal axis, on the motor housing. In the assembly position, after plastic deformation, at least one engagement element of the gearbox housing engages behind the collar or in the groove, thus establishing the connection between the gearbox housing and the motor housing. The rotationally symmetrical design of the collar or groove allows the motor housing to be attached to the gearbox housing at any angle.

[0032] By selecting the angular position of the motor housing relative to the gearbox housing, in particular the connector exit direction, along which a connector for the electrical supply of the drive motor extends, can be set as desired.

[0033] If at least one engagement element is formed as a plastically deformable element on the gearbox housing, plastic deformation of the at least one engagement element can be carried out, for example, by hot forming, for example, by using a hot stamp designed and formed for this purpose.

[0034] If at least one engagement section is formed by a radially projecting collar or a groove on the motor housing, the at least one engagement element, after plastic deformation, engages radially inwards behind the collar or into the groove. Through plastic deformation, for example by hot forming, material of the at least one engagement element is thus softened or melted to create an engagement with an undercut formed by the at least one engagement section.

[0035] In one embodiment, the at least one engagement element is formed by at least one plastically deformable pin element on the gearbox housing or the motor housing. The pin element preferably extends longitudinally along the longitudinal axis. In this case, the at least one engagement section is preferably formed by at least one opening on the other of the gearbox housing and the motor housing such that the at least one pin element can engage with the at least one opening and then be plastically deformed to establish the connection between the gearbox housing and the motor housing. The gearbox housing and the motor housing can thus be placed against each other along the longitudinal axis of the drive motor, with the at least one pin element engaging with the at least one opening.The connection between the gearbox housing and the motor housing can then be fixed by plastic deformation of at least one pin element.

[0036] Using the assembly of the type described above, a door drive device for adjusting a vehicle door relative to a vehicle body can be manufactured. Such a door drive device comprises an adjusting element for transmitting force between the vehicle door and the vehicle body, a drive motor with a motor housing, a gearbox assembly for coupling the drive motor to the adjusting element, and a gearbox housing.

[0037] The door drive device includes a connecting device which

[0038] The assembly connects the gearbox housing and the motor housing, the connecting device comprising at least one engagement section formed on one of the gearbox housing and the motor housing, and at least one engagement element formed on the other of the gearbox housing and the motor housing, which engage with each other to establish a connection between the gearbox housing and the motor housing. The advantages and advantageous embodiments described above for the assembly also apply analogously to the door drive device. The door drive device is manufactured using the assembly.

[0039] The door drive device has an adjusting element that can be moved by an electric drive motor to create an adjusting force between the vehicle door and the vehicle body. The adjusting element is connected, for example, to the vehicle body on one side and to a gear element of the transmission assembly on the other, so that by moving the adjusting element the angular position of the vehicle door relative to the vehicle body can be changed, and thus the vehicle door can be pivoted relative to the vehicle body.

[0040] The door drive device can be designed, in particular, for the automatic, electromechanical adjustment of the vehicle door between a closed and a fully or partially open position. Additionally or alternatively, the door drive device can be designed to provide electromechanical support to a user's manual adjustment of the vehicle door in servo mode, so that the user only needs to exert a minimal (and essentially constant) adjustment force over the entire adjustment range of the vehicle door, and any additional force required is provided by the drive motor of the door drive device.

[0041] In one embodiment, the door drive device comprises a guide rail connected to the gearbox housing and a sliding element coupled to the adjusting part, which is guided longitudinally along the guide rail along an adjustment direction and is adjustable by the gearbox assembly. The adjusting part is adjusted by a drive motor via a gearbox assembly, which moves a sliding element along the guide rail to introduce an adjusting force into the adjusting part. The guide rail extends longitudinally along an adjustment direction. The sliding element is guided along the guide rail along this direction and is thus movable along the guide rail in this direction.

[0042] In one embodiment, the adjusting element is pivotally connected at a first end to the sliding element and at a second end, located away from the first end, pivotally connected to the vehicle body. The adjusting element thus establishes a functional connection between the vehicle body and the door drive device located on the vehicle door, so that by adjusting the adjusting element on the door drive device, movement between the vehicle door and the vehicle body can be effected.

[0043] In one embodiment, the sliding element comprises a structural part and a sliding section arranged on the structural part for sliding contact with the guide rail. The structural part provides a rigid structure for the sliding element. The sliding section formed on the structural part, on the other hand, serves to improve the sliding properties of the sliding element for sliding in the guide rail.

[0044] In one embodiment, the gear assembly features a spindle that is rotatable about a rotary axis and driven by the drive motor. The sliding element is threaded in connection with the spindle, so that by rotating the spindle, the sliding element can be moved longitudinally along the adjustment direction. The spindle has, for example, an external thread that engages with an internal thread formed on the sliding element, so that when the spindle is rotated, the sliding element rolls along the spindle and is thus adjusted longitudinally.

[0045] In one embodiment, the sliding element has a spindle nut section with a threaded opening formed therein, in which an internal thread is formed for creating a threaded connection with the spindle. The spindle engages in the threaded opening and is thereby coupled to the spindle nut section, so that by rotating the spindle the sliding element can be adjusted axially along the spindle and thus the adjusting part for adjusting the vehicle door can be moved.

[0046] In one embodiment of the door drive device, a gear assembly similar to a spindle drive is used, through which adjusting forces can be introduced into the adjusting element for adjusting the vehicle door. Such a spindle drive can be constructed simply with just a few components and enables reliable and robust power transmission.

[0047] The spindle nut section of the sliding element is, for example, integrally and integrally formed with the sliding section, for instance by injection molding in an injection mold. During injection molding, the threaded opening with the internal thread formed within it is also integrally formed.

[0048] In one embodiment, the gearbox assembly includes a gear wheel mounted on the gearbox housing for power transmission from the drive motor to the spindle. The gear wheel can, for example, be designed as a spur gear and rotate on the spindle. The drive motor can, for example, have a drive shaft and a drive worm mounted on the drive shaft, which meshes with the gear wheel, so that a rotary motion of the shaft is converted into a (reduced) rotary motion of the gear wheel.

[0049] A door drive device of the described type can be used as a door drive on a vehicle side door, rear door, or tailgate. A door drive device of the described type can also be used, for example, to adjust a hood or a so-called frunk (i.e., a hatch in the front cargo area of ​​a vehicle), which, for the purposes of this text, are also to be understood as vehicle doors.

[0050] Accordingly, a vehicle assembly can include a vehicle door pivotably arranged on a vehicle body and a door drive device of the type described above for adjusting the vehicle door relative to the vehicle body.

[0051] A method for manufacturing the door drive device using an assembly of the type described comprises: connecting the gearbox housing and the motor housing via the connecting device, wherein the connecting device has at least one engagement section formed on one of the gearbox housing and the motor housing and at least one engagement element formed on the other of the gearbox housing and the motor housing, which are brought into engagement with each other to create a connection between the gearbox housing and the motor housing.

[0052] The advantages and beneficial designs described above for the assembly and the door drive device also apply analogously to the method.

[0089] Fig. 1 shows a schematic view of a vehicle 1 with a vehicle body 10 and a vehicle door 11 arranged pivotally on the vehicle body 10 about 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.

[0090] A door drive device 2, comprising an adjusting element 21 in the form of a sliding element, is located between the vehicle body 10 and the vehicle door 11. This adjusting element 21 is pivotally mounted on the vehicle body 10, for example, on the A-pillar of the vehicle 1, around a joint 20. When the vehicle door 11 pivots, the adjusting element 21 moves relative to the vehicle door 11. One end 211 of the adjusting element 21 extends into a door cavity 110 of the vehicle door 11 and moves within this cavity when the vehicle door 11 is adjusted.

[0091] Figures 2 to 11 show views of an embodiment of a door drive device 2, which serves to adjust an adjusting part 21 and thereby to move a vehicle door 11 relative to a vehicle body 10.

[0092] In the illustrated embodiment, the door drive device 2 has an electric drive motor 22, which serves to drive a spindle 25 of a gear assembly of the door drive device 2 that is rotatable about a rotary axis D. The drive motor 22 has a motor shaft 220 and a drive worm 221 arranged thereon with a worm gear that meshes with a gear wheel 230 in the form of a spur gear of a gearbox 23.

[0093] The gear wheel 230 is arranged on a shaft 233 and is connected via the shaft 233 to a section 250 of the spindle 25, so that the gear wheel 230 is fixed to the spindle 25.

[0094] The gear wheel 23 is rotatably mounted relative to a gear housing 24 about the axis of rotation D of the spindle 25 via bearings 231 and 234. As can be seen particularly from the partial sectional views according to Figs. 10 and 11 in conjunction with the exploded view according to Fig. 3, one bearing 231 is received in a bearing bushing 232 and supported above it in a bearing opening 240 of the gear housing 24. Another bearing 234, on the other hand, is located in a section 245 of the gear housing 24 and provides a bearing for the shaft 233 at an end of the shaft 233 opposite the bearing 231.

[0095] The door drive device 2 has a sliding element 26 and a guide rail 27. As can be seen particularly from the exploded view according to Fig. 3, the guide rail 27 is received in a receiving opening 246 of the gearbox housing 24 and is firmly connected to the gearbox housing 24 via flange sections 273.

[0096] The sliding element 26 is slidably located in the guide rail 27 such that it can be adjusted along the guide rail 27 in an adjustment direction V. The guide rail 27 has a C-shaped cross-section transverse to the adjustment direction V, formed by a base 270 and angled legs 271 extending laterally from the base 270. Edge sections 272 are formed at the ends of the legs 271 located away from the base 270 and pointing towards each other. The sliding element 26 is guided in the guide rail 27 such that it is received between the legs 271 and enclosed by the base 270, the legs 271, and the edge sections 272.

[0097] In the illustrated embodiment, the guide rail 27 is rigidly connected to the gearbox housing 24 via an adapter element 242 and the flange sections 273 abutting the gearbox housing 24 (see in particular Fig. 2 and Figs. 4 to 6). The adapter element 242 is connected to the gearbox housing 24 via fastening elements 243 in the form of screws with the flange sections 273 interposed between them 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.

[0098] The adapter element 242 serves to fix the door drive device 2 to the vehicle door 11, in particular to the inner door panel of the vehicle door 11, such that the door drive device 2 is arranged within the interior of the vehicle door 11. The adapter element 242 thus provides an interface that is customer-specific and therefore enables the mounting of the door drive device 2 to the vehicle door 11 of a respective vehicle model.

[0099] The adapter element 242 is arranged at the end face of the guide rail 27 and extends in a plate-like shape transversely to the adjustment direction V, along which the sliding element 26 with the adjusting part 21 attached to it is to be moved towards the guide rail 27. The adjusting part 21 extends through an opening 242A in the adapter element 242, is guided out of the door interior through the opening 242A and is supported on the vehicle body 10 via the joint 20.

[0100] The sliding element 26 has a structural part 260, which has a base 261 and legs 262 angled towards the base 261. The structural part 260 is partially overmolded with a plastic material, through which sliding sections 263 are formed on the outside of the legs 262. The sliding element 26 is in contact with the guide rail 27 via these sliding sections. An end 211 of the adjusting part 21 is pivotally connected to the sliding element 26 via a coupling element in the form of a ball head. Due to the pivotal connection, the adjusting part 21 is pivotally connected to the sliding element 26 about the adjustment direction V and also about axes perpendicular to the adjustment direction V, so that tolerances in the position of the adjusting part 21 relative to the sliding element 26 can be compensated for.

[0101] Furthermore, the sliding element 26 has a spindle nut section 264 which forms a threaded opening 265 with an internal thread formed therein. The spindle 25 engages in the threaded opening 265 with a threaded section 251, so that the spindle 25 is in threaded engagement with the spindle nut section 264 of the sliding element 26 via an external thread formed on the outside of the threaded section 251.

[0102] As can be seen from Fig. 3 in conjunction with Fig. 10, a cover element 241 is arranged on the gearbox housing 24, which covers the guide rail 27 on the side of the edge sections 272 and thus encloses the spindle nut section 264 of the sliding element 26 outwards along the path of movement defined by the guide rail 27.

[0103] The adjusting element 21 is pivotally coupled at one end 210 via a pivot pin 200 about a pivot axis G to a joint 20, which is rigidly connected to the vehicle body 10, as shown schematically in Fig. 1. At the end 211, which is located away from the end 210, the adjusting element 21 is pivotally coupled to the sliding element 26. By adjusting the sliding element 26, driven by the drive motor 22, the end 211 of the adjusting part 21 can be moved in the guide rail 27, so that the adjusting part 21 can be adjusted between a first, retracted position (Figs. 4 to 6 and Fig. 10) and a second, extended position (Figs. 7 to 9 and Fig. 11) in order 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 adjusting part 21) and an open position (corresponding to an extended position of the adjusting part 21).

[0104] As can be seen from the partially cutaway view in Fig. 10, in the first, retracted position, the sliding element 26 is away from the gearbox housing 24 and approaching an end of the guide rail 27 that is farther from the adapter element 242. In the second, extended position, the sliding element 26 is moved towards the gearbox housing 24, so that the spindle nut section 264 is close to the gearbox 23 and the adjusting part 21 is moved with its end 211 in the adjustment direction V towards the adapter element 242.

[0105] In the second position, the sliding element 26, together with the structural part 260, moves beneath 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 Fig. 11. This enables a space-efficient design of the drive device 2, with a comparatively large stroke of the adjustment part 21 along the adjustment direction V and a low overall height transverse to the adjustment direction V, in particular vertically along the pivot axis G.

[0106] As can be seen in Fig. 9, a longitudinal axis L, about which the motor shaft 22 of the drive motor 22 is rotatable, can be inclined to the joint axis G, about which the adjusting element 21 at end 210 is pivotally connected to the joint 20. This can contribute to a saving of installation space, particularly along a transverse direction (transverse to the joint axis G and transverse to the adjustment direction V). However, the longitudinal axis L can also be aligned with the joint axis G.

[0107] The door drive device 2 can be installed in a vehicle door 11 with the drive motor 22 facing upwards, or alternatively with the drive motor 22 facing downwards. The drive motor 22 can also be arranged at an end of the guide rail 27 opposite the end of the guide rail 27 where the adjusting element 21 exits the guide rail 27. This allows the door drive device 2 to be used universally on different door models of different vehicles.

[0108] In the door drive device 2, the vehicle door 11 is adjusted relative to the vehicle body 10 by moving the adjusting element 21 along the adjustment direction V via the drive motor 22 by sliding the sliding element 26 on the guide rail 27. A force flow is established between the vehicle door 11 and the vehicle body 10, which runs from the vehicle door 11 via the adapter element 242, the gearbox housing 24, the drive wheel 23, the spindle 25, the sliding element 26, and the adjusting element 21 to the vehicle body 10. For adjustment, a force is introduced into the sliding element 26 via the drive motor 22, and this force moves the sliding element 26 on the spindle 25, thus adjusting the adjusting element 21 and pivoting the vehicle door 11 relative to the vehicle body 10.

[0109] In the door drive device 2, the sliding element 26 is guided along the adjustment direction V on the guide rail 27, so that driven by the drive motor 22 and the gearbox 23, the sliding element 26 is adjusted and the adjustment part 21 can be moved to pivot the vehicle door 11.

[0110] Figures 12 to 15 show an embodiment of an assembly of a door drive device 2, which in its operation corresponds to the embodiment described above with reference to Figures 2 to 11, so that with regard to the operation of the door drive device 2 in its operating state, reference should be made to the preceding explanations.

[0111] The door drive device 2 according to Figures 12 to 15 has a connecting device 28, via which a motor housing 222 of the drive motor 22 is to be connected to the gearbox housing 24 for mounting the door drive device 2. To implement the connecting device 28, an attachment section 280 is formed on the gearbox housing 24, which is cylindrical with respect to the longitudinal axis L of the drive motor 22 and to which the motor housing 222 is to be attached for mounting the door drive device 2.

[0112] A housing section 247 connects to the attachment section 280, into which the drive element 221 in the form of the drive worm can be inserted by attaching the motor housing 222 to the attachment section 280, and which receives the drive element 221 in an assembly position when the door drive device 2 is mounted.

[0113] The motor shaft 220, with the drive element in the form of the drive worm 221 arranged on it, is rotatable about the longitudinal axis L during operation. With respect to the longitudinal axis L, the motor housing 222, for example formed by a tubular metal part, is cylindrical and can be connected along the longitudinal axis L to the mounting section 280 of the gearbox housing 24.

[0114] In the illustrated embodiment, a housing part 29 with a connector 290 attached to it is arranged on the motor housing 222. An electrical connection can be made via the connector 290 to supply the drive motor 22 with electricity.

[0115] In the illustrated embodiment, engagement elements 282, 283 are formed in the form of punched-out tabs in the area of ​​a lower edge of the cylindrical motor housing 222 facing the mounting section 280. When the motor housing 222 is attached to the mounting section 280, the engagement elements 282, 283, which are formed as tabs, can be plastically deformed on the motor housing 222 such that the engagement elements 282, 283 engage together in an associated engagement section 281 in the form of a recess on the mounting section 280, thus establishing a positive-locking or force-locking connection between the gearbox housing 24 and the motor housing 222.

[0116] In the illustrated embodiment, a plurality of engagement sections 281 in the form of recesses are regularly arranged around the longitudinal axis L on the mounting section 280. This makes it possible to connect the motor housing 222 to the gearbox housing 24 in different discrete angular positions, as can be seen in Figures 13 to 15, which show the motor housing 222 in different mounting positions on the gearbox housing 24. In each mounting position according to Figures 13, 14 and 15, the engagement elements 282, 283 in the form of tabs on the motor housing 222 engage in one of the engagement sections 281 on the mounting section 280 and thus establish a connection between the gearbox housing 24 and the motor housing 222.

[0117] The engagement sections 281 are formed as recesses in the form of depressions or through openings on the attachment section 280. The recesses point radially inwards and thus allow the engagement elements 282, 283, which are shaped as tabs, to engage in order to establish a positive-locking or force-locking connection between the gearbox housing 24 and the motor housing 222.

[0118] By selecting a suitable angular position of the motor housing 222 relative to the gearbox housing 24, a desired exit direction for the connector 290 can be set in order to obtain a space-saving arrangement with advantageous routing of a connecting cable.

[0119] In the embodiment shown in Figures 12 to 15, a group of three engagement elements 282, 283 in the form of tabs is formed on the motor housing 222, wherein a first engagement element 282 points axially along the longitudinal axis L and further engagement elements 283 point towards each other along a circumferential direction around the longitudinal axis L. In an assembly position, the engagement elements 282, 283 engage together in one of the engagement sections 281 and thus establish a connection between the motor housing 222 and the gearbox housing 24.

[0120] For example, diametrically opposite the group of engagement elements 282, 283, another group of engagement elements 282, 283 can be formed on the motor housing 222 to create a symmetrical connection with symmetrical force absorption between the motor housing 222 and the gearbox housing 24.

[0121] By reshaping the engagement elements 282, 283, in particular a crimp connection can be created which can absorb both axial forces acting between the motor housing 222 and the gearbox housing 24 as well as torques about the longitudinal axis L.

[0122] In an embodiment shown in Figures 16 to 18, (only) an axially projecting engagement element 282 is formed on the motor housing 222, wherein, diametrically opposite to the engagement element 282, for example, another axially aligned engagement element 282 may be formed on the motor housing 222. Engagement elements 283 aligned along a circumferential direction, as in the embodiment according to Figures 12 to 15, are not present here.

[0123] Accordingly, circumferentially arranged engagement sections 281 can be designed to be narrower at the attachment section 280 (viewed in the circumferential direction), so that more engagement sections 281 can be formed in the form of recesses at the attachment section 280, thus enabling a connection of the motor housing 222 with the gearbox housing 24 in a larger number of discrete angular positions.

[0124] Figs. 17, 18 and 19 show the motor housing 222 in mounting positions with different angular positions relative to the gearbox housing 24.

[0125] Otherwise, the embodiment shown in Figs. 16 to 19 is identical to the embodiment shown in Figs. 12 to 15, so reference should also be made to the preceding explanations.

[0126] In the embodiments shown in Figures 12 to 19, the housing part 29, which forms the connector 290, is attached to the motor housing 222 as a separate housing part. As can be seen from the embodiment shown in Figures 20 to 22, the housing part 29 has an annular section 291 which is sealed moisture-tight relative to the motor housing 222 by a first sealing element 292 in the form of a circumferential sealing element and relative to the attachment section 280 by a second sealing element 293 in the form of a circumferential sealing element, when the motor housing 222 is mounted on the attachment section 280, as can be seen in particular from the sectional views shown in Figures 21 and 22.

[0127] In the assembled position, the drive element 221 is received on the motor shaft 220 in the housing section 247 of the gearbox housing 24, as can be seen from the sectional views in Figures 21 and 22. A bearing element 225 in the form of a ball bearing provides support for the motor shaft 220 on the gearbox housing 24.

[0128] In the embodiment shown in Figures 20 to 22, a group of engagement elements 282, 283 is formed on the motor housing 222, analogous to the embodiment shown in Figures 12 to 15. On the attachment section 280, (only) an associated engagement section 281 is formed in the form of a recess, with which the engagement elements 282, 283 can be brought into engagement by plastic deformation for assembly, in order to establish a connection between the motor housing 222 and the gearbox housing 24. A further engagement section 281 can optionally be formed diametrically opposite the attachment section 280 in order to create a symmetrical connection and thus symmetrical force transmission between the motor housing 222 and the gearbox housing 24 by engaging with a further group of engagement elements diametrically opposite the engagement elements 282, 283.

[0129] In an embodiment shown in Figures 23 to 25, an engagement element 282' in the form of a radially outwardly projecting projection is formed on the mounting section 280 of the gearbox housing 24. This projection can be engaged with an engagement section 281' in the form of a bayonet opening on the motor housing 222 to connect the gearbox housing 24 to the motor housing 222. For assembly, the motor housing 222 and the gearbox housing 24 are placed against each other along the longitudinal axis L of the drive motor 22, so that the engagement element 282' engages with the engagement section 281' in the form of the bayonet opening on the motor housing 222, as can be seen in Figure 24. By rotating the motor housing 222 about the longitudinal axis L relative to the attachment section 280, the engagement element 282' can then be locked relative to the engagement section 281', as can be seen from Fig. 25.

[0130] While in the embodiments according to Figs. 12 to 22 the connection between the motor housing 222 and the gearbox housing 24 is made by plastic deformation at the engagement elements 282, 283 and the connection between the motor housing 222 and the gearbox housing 24 cannot be released non-destructively after assembly, in the embodiment according to Figs. 22 to 25 the connection between the motor housing 222 and the gearbox housing 24 can be released by removing the bayonet connection between the motor housing 222 and the gearbox housing 24.

[0131] To create a symmetrical connection with symmetrical force application, in the embodiment according to Figures 22 to 25, a further engagement element 282' can be formed diametrically opposite the engagement element 282' on the attachment section 280. Similarly, a further engagement section 28T can be formed on the motor housing 222 diametrically opposite the engagement section 281' to create a bayonet connection.

[0132] In an embodiment shown in Figs. 26 to 29, engagement elements 282” are formed by claw elements projecting axially from an attachment section 280, between which an engagement section 281” in the form of a circumferential collar is inserted on the motor housing 222 for mounting the motor housing 222 with the gearbox housing 24, in order to then create a positive-locking or force-locking connection between the gearbox housing 24 and the motor housing 222 by plastic deformation, in particular hot forming, on the engagement elements 282”.

[0133] In particular, the engagement elements 282” can each be plastically deformed in the area of ​​an upper edge 285, so that material of the engagement elements 282” engages behind the engagement section 281” in the form of the circumferential collar and thus a connection is established between the motor housing 222 and the gearbox housing 24.

[0134] The engagement elements 282” are diametrically opposed to each other and project axially from the insertion section 280. In a starting position, the edge sections 285 project radially inwards, whereby the edge sections 285 can be engaged with the collar-shaped engagement section 281” in the area of ​​complementary flattened areas 284 to establish the connection between the motor housing 222 and the gearbox housing 24. After engagement, the motor housing 222 can be freely aligned about the longitudinal axis L relative to the insertion section 280 in order to set a desired angular position of the motor housing 222 relative to the gearbox housing 24, as can be seen in the views according to FIGS. 28 and 29, which show the motor housing 222 in different angular positions relative to the gearbox housing 24.

[0135] After the motor housing 222 is attached to the attachment section 280 on the gearbox housing 24, the engagement elements 282” are plastically deformed, so that the material of the engagement elements 282” runs behind the collar-shaped engagement section 281” and thus engages behind the engagement section 281”, particularly in the area of ​​the edge section 285. In the assembled position, the motor housing 222 is thus fixed relative to the gearbox housing 24 and, in particular, also held against rotation. In an embodiment shown in Figs. 30 to 32, engagement elements 282”’ in the form of axially projecting pin elements are formed in the area of ​​the attachment section 280 on the gearbox housing 24, which are brought into engagement with associated engagement sections 281”’ in the form of openings formed on radially projecting tabs by attaching the motor housing 222 along the longitudinal axis L to the gearbox housing 24, as can be seen in the transition from Fig. 30 to Fig. 31.

[0136] By plastic deformation of the pin elements, in particular by hot forming of the heads of the pin elements, a positive locking connection is created between the motor housing 222 and the gearbox housing 24, so that the motor housing 222 is fixed to the gearbox housing 24, as can be seen in Fig. 32.

[0137] In an embodiment shown in Figures 33 to 35, the motor housing 222 can be attached to a mounting section 280 on the gearbox housing 24 along the longitudinal axis L, so that the tubular motor housing 222 engages in the mounting section 280, as can be seen in Figures 33 and 34. Once the motor housing 222 has been attached to the gearbox housing 24, an upper edge 282”” of the mounting section 280 can be plastically deformed, in particular by hot forming, and brought into engagement with a friction section 281”” in the form of a circumferential groove on the motor housing 222, thus establishing a connection between the motor housing 222 and the gearbox housing 24, as can be seen in Figure 35. By hot forming at the edge 282””, the material of the edge 282”” enters the groove on the motor housing 222 and thus creates a connection between the motor housing 222 and the gearbox housing 24.The edge 282”” thus realizes an engagement element on the attachment section 280 on the side of the gearbox housing 24.

[0138] Because the rim 282””” and the groove 281”” are formed rotationally symmetrically on the mounting section 280 on the side of the gearbox housing 24 and on the side of the motor housing 222, respectively, the motor housing 222 can be attached to the gearbox housing 24 and connected to it at any angular position. In the connected assembly position, the motor housing 222 is then load-bearing and also rotationally fixed relative to the gearbox housing 24 due to the plastic deformation at the rim 282””. The underlying concept of the invention is not limited to the embodiments described above, but can also be realized in completely different embodiments. A door drive device of the described type can be used, in particular, on a vehicle side door as well as on a tailgate.A door drive device of the type described can also be used, for example, to adjust a bonnet or a so-called frunk (i.e., a flap in the front cargo area of ​​a vehicle), which in the context of this text are also to be understood as vehicle doors.
