Description

drive unit

The invention relates to a drive unit for a drive for adjusting an adjusting element of a motor vehicle according to the preamble of claim 1, a drive unit for a drive for adjusting an adjusting element of a motor vehicle according to the preamble of claim 19, a drive unit for a drive for adjustment an adjusting element of a motor vehicle according to the preamble of claim 20 and a drive for adjusting an adjusting element of a motor vehicle according to claim 21.

The term “adjustment element” is to be understood broadly in the present case. It includes, for example, flaps such as tailgates, boot lids, bonnets, side doors, luggage compartment flaps or the like, or sliding doors of a motor vehicle.

The known drive (DE 10 2008 062 400 A1), on which the invention is based, has a drive for adjusting a tailgate of a motor vehicle, which is designed as a spindle drive. The drive has a drive unit with an electric drive motor and a feed gear in the form of a spindle

Spindle nut gear, which is used to generate drive movements along a geometric drive axis between a first and a second drive connection of the drive. The spindle-spindle nut gear has, in a conventional manner, a spindle driven by the drive unit and a spindle nut meshing with it, which, since it is secured against rotation, converts a rotational movement of the spindle into a linear movement of the two drive connections relative to one another. In this way, the tailgate can be adjusted electrically between an open position and a closed position.

The drive unit also has a cable module with a motor circuit board that is electrically connected to the drive motor. The cable module is arranged in the axial extension of the drive motor in a section between the drive motor and the joint part of the drive connection that is axially fixed thereto in a common housing section. This is a particularly compact design of a drive for adjusting a Control element of a motor vehicle. One challenge, however, is to establish the connection between the articulated part and the cable module, specifically the cable module cover of the cable module, as easily and securely as possible. In the known drive unit, for example, the joint part is introduced radially into the cable module cover and is connected to it in an axially fixed manner. The axially fixed connection must also withstand the forces, in particular the tensile forces, which can occur, for example, in a case when a user manually actuates the adjustment element with excessive force, in particular opens it. It is also desirable to produce the unit made up of joint part and cable module cover using as inexpensive a material as possible.

The invention is based on the problem of designing and developing the known drive unit in such a way that it can be manufactured as simply and inexpensively as possible.

The above problem is solved by the features of the characterizing part of claim 1 in a drive unit having the features of the preamble of claim 1. The fundamental consideration is to design the cable module or its cable module cover, which also serves to connect the cable module to the drive unit, on the one hand, and the articulated part of the drive connection on the cable module side, on the other hand, in such a way that these two components are connected to one another after they have been brought together during assembly are engaged that in the axial direction there is a form fit. In order to connect the cable module or cable module cover and joint part to one another in an axially fixed manner, the proposed drive unit requires only one assembly movement of the joint part relative to the cable module, with this assembly movement at the same time already generating the axially fixed form fit. Measures to produce an axially fixed connection between the two components that go beyond this assembly movement of the articulated part relative to the cable module can thus be simpler. In particular, it is not absolutely necessary to create a particularly secure, axially strong connection to connect the articulated part to the cable module in a costly and materially bonded manner, for example by means of an expensive, high-strength and high-temperature-resistant adhesive or by particularly complex welding. Equal- but it is not impossible to provide an additional integral connection between the joint part and the cable module in the proposed drive unit as well. The proposed separate provision of the joint part on the one hand and the cable module on the other hand also offers the advantage of using a different, in particular cheaper, material for the cable module cover than for the joint part. As will be explained below, the material of the cable module cover can have a lower temperature resistance and/or tensile strength than the material of the joint part.

In detail, it is proposed that during the assembly of the drive unit the engagement section of the joint part can be brought together with the corresponding counter-engagement section of the cable module cover in one assembly movement such that in the assembled state the engagement section and the counter-engagement section engage in one another in an axially fixed manner.

Claim 2 specifies the assembly movement in such a way that it preferably includes or is at least one component that is orthogonal to the geometric drive axis, in particular a radial component. The joint part and the cable module are therefore preferably brought together in one direction at an angle to the geometric drive axis during assembly. In this way, not only can the axially fixed connection be produced in a particularly simple manner, but bringing the two components together in this way also has the effect, in particular, of producing an anti-twist device between them.

In claim 3, the engagement portion and the corresponding counter-engagement portion are defined in more detail. One is a recording into which the other is inserted. At least the axial form fit is then produced by the insertion, in that the receptacle forms an undercut. In addition, said anti-rotation lock can also be produced by pushing it in.

Claims 4 and 5 relate to ways of securing the engagement section and the counter-engagement section, ie the articulated part and the cable module cover, to one another, so that the two components can be secured in the assembled state cannot move apart. Such a safeguard can be achieved by latching (claim 4) and/or by pushing a housing part, in particular tubular, onto the cable module cover (claim 5). The housing part is particularly preferably part of the drive housing and in particular forms the outer housing tube or, if appropriate, the inner housing tube of a telescoping drive housing.

Claim 6 defines different configurations of the particular tubular housing part. This can then not only be part of the drive housing of the drive, but also part of a drive unit housing that is designed to accommodate at least the drive motor and the cable module. Such a drive unit housing is also referred to as a drive cartridge. In contrast to the drive unit housing, the drive housing also accommodates a feed gear, for example a spindle-spindle nut gear, of the drive. The housing part of the drive unit housing and/or the housing part of the drive housing is preferably connected in an axially fixed manner to the cable module cover.

According to the preferred embodiment according to claim 7, the joint part has, in addition to the engagement section, a bearing section which is mounted in the endmon-oriented state on the counter-joint part on the motor vehicle side. Engagement section and bearing section are connected to one another via a connecting section, in particular in one piece. The bearing section is configured as a ball socket, for example.

Claim 8 specifies the material which is preferably used for the cable module cover and/or the joint part.

According to the particularly preferred embodiment according to claim 9, the cable module cover is designed in one piece or in multiple pieces, in particular in two pieces. The cable module cover thus has at least two, preferably exactly two, separate cover parts which are connected to one another during assembly and then together form the cable module cover. According to the likewise preferred embodiment according to claim 10, the cable module cover has a housing closing part and a cable connection part. The housing end part and the cable connection part of the cable module cover are then preferably brought together during assembly in an assembly movement (claim 11), which can be done at an angle, in particular orthogonally, to the geometric drive axis or parallel to it.

Claims 12 and 13 relate to options for securing the housing end part and the cable connection part, ie the at least two separate components of the cable module cover, to one another so that the two components cannot move apart when assembled. Such a fuse can be achieved by latching (claim 12) and/or by sliding one of the tubular housing parts, in particular, onto the unit comprising the housing termination part and cable connection part (claim 13). This safety function is particularly preferably effected by the housing part of the drive housing, in particular by the outer housing tube or possibly the inner housing tube of the telescoping drive housing. Additionally or alternatively, this safety function is effected by the housing part of the drive unit housing. According to the likewise preferred embodiment according to claim 14, the electrical contact is made between the line or lines of the cable module with the drive motor and/or the motor circuit board as a result of the assembly movement of the cable connection part relative to the housing. Additionally or alternatively, this assembly movement can also be used to position a motion sensor attached to the cable connection part, in particular a Hall sensor, relative to the housing closure part in such a way that, when assembled, it is within the effective range of a magnet on the motor shaft of the drive motor. This ensures that the drive unit and thus the entire drive can be manufactured in a particularly simple manner.

Particularly preferred options for connecting the cable module cover and joint part and/or between the cable connection part and housing end part are the subject of claim 15. Claims 16 to 18 relate to configurations in which the one or more lines are installed in a line bushing can be clamped in a simple way and can be fixed in this way on the cable module cover. A casting compound for axial attachment of the one or more lines to the cable module cover can thus be dispensed with, which saves costs and at the same time simplifies assembly.

According to a further teaching according to Claim 19, which is of independent importance, a drive unit for a drive, in particular a spindle drive, is claimed for adjusting an adjustment element of a motor vehicle, the drive unit housing an electric drive motor with a motor housing, a cable module with a motor circuit board, the is electrically connected to the drive motor, and with a cable module cover, into which one or more lines for the electrical connection with the drive motor and the motor circuit board lead, at least one in particular tubular housing part, which is axially connected to the cable module cover in relation to a geometric drive axis, as well as a joint part which, together with a counter joint part on the motor vehicle side, forms a first drive connection. In detail, it is proposed here that the cable module cover should have a housing end part, to which the tubular housing part in particular is connected in an axially fixed manner and which is cable-free, especially in the unassembled state, and a cable connection part, into which the one or more cables for the electrical connection to the drive motor and of the motor circuit board, in particular already in the unassembled state, and that during the assembly of the drive unit the housing end part can be brought together with the cable connection part in an assembly movement which is a movement with a radial and/or parallel movement in relation to the geometric drive axis Component includes or is.

According to a further teaching according to claim 21, which is also of independent importance, a drive, in particular a spindle drive, is claimed for the adjustment of an adjustment element of a motor vehicle, the drive having a proposed drive unit, the drive being a feed gear, in particular Special spindle-spindle nut gear, for generating drive movements along a geometric drive axis between a first drive connection and a second drive connection. In this respect, reference may be made to all statements relating to the proposed drive unit according to the first teaching, to the proposed drive unit according to the second teaching and to the proposed drive unit according to the third teaching. The joint part of the drive unit preferably forms one of the drive connections together with a counter-joint part on the motor vehicle. The second drive port is formed by another joint part together with a corresponding other vehicle-side counter joint part. The other joint part is coupled in an axially fixed manner to an output-side gear component of the feed gear, in particular to the spindle nut of the spindle-spindle nut gear.

The invention is explained in more detail below with reference to a drawing that merely shows exemplary embodiments. In the drawing shows

6 shows part of a further exemplary embodiment of a drive unit a) during assembly and b) in the assembled state, and part of yet another exemplary embodiment of a drive unit c) during assembly and d) in the assembled state. The drive unit 1 shown in the figures is part of a drive 2, here a spindle drive, for adjusting an adjusting element 3 of a motor vehicle. The adjusting element 3 is here and preferably as a patch flap. All the explanations for a spot flap also apply to all other types of adjustment elements 3 of a motor vehicle. In this respect, reference may be made to the list of examples in the introductory part of the description.

Drive 2 is used to adjust the spot flap. For this purpose, the drive 2 is articulated on the motor vehicle body on the one hand and on the adjusting element 3 on the other hand. The drive 2 generates here and preferably linear drive movements along a geometric drive axis 4, so that the adjustment element 3 can be adjusted between a closed position and the open position shown in FIG. This adjustment takes place by means of an electrical drive motor 5 which, as will be explained below, generates a driving force which causes the adjustment element 3 to be adjusted.

The drive motor 5 of the drive unit 1, which has its own motor housing 5a, is arranged in a drive unit housing, also called a drive cartridge, which is shown uncut in FIGS. 2a) and b) in the upper section of the drive 2. Here and preferably, the drive unit 1, downstream of the drive motor 5 in terms of drive technology, has one or more further drive unit components such as an intermediate gear, for example planetary gears, a brake, a clutch or the like, with the drive unit components, in particular one behind the other along the geometric drive axle 4, each together with the drive motor 5 can also be arranged in the drive unit housing to.

The drive unit 1 is further connected in terms of drive technology to a feed gear 6 which will be explained in more detail below. The feed gear 6 is arranged together with at least the drive motor 5, in particular the entire drive unit 1, in a common drive housing of the drive 2, which is here and preferably telescopic and in particular configured tubular. For this purpose, the drive housing has an outer, in particular tubular, housing part 2a and an inner, in particular tubular, housing part 2b. The term “telescopic” in this context means that the outer housing part 2a and the inner housing part 2b can be displaced relative to one another in the axial direction, with the inner housing part 2b being guided in the outer housing part 2a.

“Axial” here always means the direction of the geometric drive axis 4 . Correspondingly, “radial” means the direction orthogonal to it.

Furthermore, as shown in the views in FIGS. 3 to 5, the drive unit 1 has a cable module 7 with a motor circuit board 8 which is electrically connected to the drive motor 5 . The drive unit housing of the drive unit 1 also serves to accommodate the cable module 7.

The term "motor circuit board" is to be understood broadly in the present case. It includes both single-layer and multi-layer boards. It also includes rigid, flexible and rigid-flex circuit boards. A motor circuit board 8 in the above sense regularly has conductor tracks and electrical and/or electronic compo elements. Such a motor circuit board 8 can be used to control the drive motor 5 and/or other components of the drive unit 1 and/or the drive 2 . The cable module 7 has a cable module cover 9, in which, from outside the drive unit 1, one or more lines 10 for electrical connec tion with the drive motor 5 and the motor board 8 lead. Furthermore, the cable module 7 for fixing the motor circuit board 8 as a lower part 11 on the drive motor side has a circuit board holder which lies axially between the drive motor 5 and the cable module cover 9 and is brought together axially with the cable module cover 9 during assembly. In particular, the cable module cover 9 and base 11 then touch and/or are secured to one another axially and, in particular, radially. The bottom part 11 of the cable module 7 allows the motor circuit board 8 to be fixed radially on the one hand and axially on the other hand, in particular axially in both directions, in relation to the cable module 7 . The lower part 11 is arranged unit housing here in an axial section of the drive unit, which lies axially between the drive motor 5 and the cable module cover 9 .

At least one particularly tubular housing part 1a, 2a, which, as will be explained below, can be part of the drive unit housing or drive housing, is axially fixed to the cable module cover 9 with respect to the geometric drive axis 4. Here and preferably the respective housing part 1a, 2a acts directly on the cable module cover 9. In general, the cable module cover 9 can be plugged into the respective housing part 1a, 2a, but alternatively can also be plugged onto this.

The drive unit 1 also has a joint part 12 which, together with a corresponding counter-joint part 13 on the motor vehicle side, forms a first drive connection 14a of the drive 2 . This is shown in FIG. 2 at the upper end of drive 2 . At the opposite, lower end there is a second drive connection 14b, which is designed in a corresponding manner.

The cable module cover 9 is preferably a component which closes the respective housing part 1a, 2a axially to the joint part 12, in particular in a sealing manner.

Furthermore, as illustrated in FIGS. 3 to 5, it is provided that the joint part 12 has an engagement section 15 and the cable module cover 9 has a corresponding counter-engagement section 16 . It is now essential that during the assembly of the drive unit 1 the engagement section 15 of the joint part 12 can be brought together with the corresponding counter-engagement section 16 of the cable module cover 9 in one assembly movement such that in the assembled state the engagement section 15 and the counter-engagement section 16 engage in one another in an axially fixed manner . With a Mon daily movement is meant a movement necessary for the purpose of assembly. This special design of the drive unit 1 shown here allows the production of an axially fixed connection between the cable module 7 and the articulated part 12 in a simple manner. It is also possible to provide the cable module cover 9 and the articulated part 12 from different materials, which reduces the costs of the drive unit 1 can become.

In detail, it is here and preferably so that the assembly movement which brings the engagement section 15 together with the counter-engagement section 16 comprises or is a movement with a radial component relative to the geometric drive axis 4 . The movement can also be a movement directed at an angle to the geometric drive axis 4 . It is essential, however, that in the assembled state there is an axial form fit between the cable module cover 9 and the joint part 12 . In the exemplary embodiments shown here, the assembly movement includes or is a purely radial movement in relation to the geometric drive axis 4 .

Furthermore, here and preferably the assembly movement that brings together the engagement section 15 with the counter-engagement section 16 is a linear, in particular purely linear, movement.

As FIGS. 3 to 5 also show, here and preferably the engagement section 15 is inserted into a receptacle in the cable module cover 9, the section 16 forming the counter engagement section. In principle, it is also conceivable, according to an alternative embodiment not shown here, for the counter-engagement section 16 to be pushed into a receptacle in the joint part 12, which then forms the engagement section 15. Furthermore, it is preferably provided here that the engagement section 15 and counter-engagement section 16, in particular their shape and/or material, are designed such that they form a predetermined breaking point when they are brought together. Here, the engagement section 15 is essentially plate-shaped, whereas the counter-engagement section 16 forms an insertion slot. The counter-engagement section 16 forms an undercut in the axial direction for the engagement section 15, so that an axial form fit is produced here. If a specified tensile force between the cable module cover 9 and the articulated part 12 is then exceeded, for example in the event of a misuse, the connection between the engaging section 15 of the articulated part 12 and the counter-engaging section 16 of the cable module cover 9 breaks in the sense of a predetermined breaking point, so that the articulated part 12 with the motor vehicle-side counter-joint part 13 and the cable module cover 9 with the drive unit 1 or the drive 2 otherwise remains connected. In this way, further damage to drive unit 1 or drive 2 is prevented. In such a case, it is also prevented that a helical compression spring, which may be located in the drive 2 and which preloads the drive connections 14a, 14b against one another, suddenly relaxes, which could lead to injuries to the user.

Here, and preferably, it is also the case that the counter-engagement portion 16 and the engagement portion 15 brought together with it are secured to one another in the radial direction and in particular also in the axial direction. In the assembled state, the engagement section 15 and the counter-engagement section 16 are preferably latched together, here in the radial direction. For this purpose, the outer contour of the here plate-shaped engagement section 15 and the corresponding inner contour of the counter-engagement section 16, as indicated for example in FIG.

Additionally or alternatively, as is also shown in Fig. 3, the particularly tubular housing part 2a or one of the particularly tubular housing parts 1a, 2a in the assembled state can secure the engagement section 15 and the counter-engagement section 16 brought together with it in the radial direction relative to one another, so that Engagement section 15 and counter-engagement section 16 then can no longer be moved apart in the radial direction. Here, and preferably, it is provided that the respective housing part 2a radially surrounds the cable module cover 9, at least in an axial section, and covers the engagement section 15 radially outwards and thereby secures it.

During assembly, the engagement section 15 is first brought together with the counter-engagement section 16 and then the respective housing part 2a is pushed onto the cable module cover 9 until the housing part 2a covers the engagement section 15 radially outwards. The cable module cover 9 and the lower part 11 of the cable module 7 on the drive motor side are also secured to one another axially and in particular radially, here and preferably by the housing part 1a.

The particularly tubular housing part 1a or one of the particularly tubular housing parts 1a, 2a here and preferably forms at least part of the drive unit housing. Here the housing part 1a forms an essentially cylindrical shell of the drive unit housing. Furthermore, here and preferably the particularly tubular housing part 2a or one of the particularly tubular housing parts 1a, 2a forms at least part of the drive housing of the drive 2. Here the housing part 2a forms the upper part of the drive housing, with a further housing part 2b of the drive housing in the housing part 2a is guided telescopically. The housing parts 2a, 2b are designed here in particular as housing tubes. The drive housing of the drive 2 is suitable due to the two telescoping housing parts 2a, 2b, in addition to the drive motor 5 and the Kabelmo module 7 and also said feed gear 6. This has here, and preferably as a spindle-spindle-nut gear, a spindle 17 that is drivingly coupled to the drive motor 5 and a spindle nut 18 that meshes with it in a conventional manner. The spindle 17 is axially fixed to the first drive connection 14a and the spindle nut 18 to the second drive connection 14b, so that when the feed gear 6 is actuated, the first drive connection 14a and the second drive connection 14b can be moved linearly relative to one another, as was already explained at the beginning. It should be emphasized that here the housing part 2a, which forms part of the drive housing of the drive 2, is the housing part that secures the engagement section 15 and counter-engagement section 16 to one another. In principle, however, it is also conceivable in an alternative embodiment not shown here that the housing part 1a, which in particular secures the cable module cover 9 and lower part 11 to one another axially, also secures the engagement section 15 and counter-engagement section 16 to one another.

3 also shows that the engagement section 15 is connected via a connection section 19 of the joint part 12 to a bearing section 20 of the joint part 12, which is supported on the counter-joint part 13 on the motor vehicle side in the final assembled state. Here, and preferably, the bearing section 20 is designed as a ball socket, which forms a ball joint with a corresponding counterpart of the counter-joint part 13 on the vehicle side. The “finally assembled state” here means the state in which the drive 2 is fitted to the motor vehicle as intended. Particularly preferably, the engagement section 15, the connection section 19 and/or the bearing section 20 are configured in one piece together. Here and preferably it is further provided that the cable module cover 9 is designed from a plastic and/or the joint part 12 is designed from a plastic or metal. The cable module cover 9 preferably has a lower temperature resistance and/or a lower tensile strength than the joint part 12 . Such a material is less expensive than a high-strength, high-temperature-resistant material, as is preferably provided for the joint part 12 . The joint part 12 is designed, for example, from poly amide or steel. The joint part 12 has, for example, a temperature resistance (so-called brief operating temperature) of more than 180° C., preferably more than 200° C., more preferably more than 220° C., and/or a tensile strength of more than 120 MPa, preferably greater than 150 MPa, more preferably greater than 180 MPa. The cable module cover 9 is designed, for example, from POM (polyoxymethylene). The cable module cover 9 has, for example, a temperature resistance of between 110° C. and 170° C., preferably between 120° C. and 160° C., more preferably between 130° C. and 150° C., and/or a tensile strength of between 40 MPa and 90 MPa, preferably between 50 MPa and 80 MPa, more preferably between 60 MPa and 70 MPa.

The previous statements related primarily to a cable module cover 9, which is designed in one piece (Fig. 3). In principle, however, it is also conceivable to design a cable module cover 9 in several parts, in particular in two parts (FIGS. 4 and 5), which will be described in more detail below.

As shown in the exemplary embodiments in FIGS. 4 and 5, the cable module cover 9 here preferably has a housing end part 21, with which the particularly tubular housing part 1a, 2a is connected in an axially fixed manner and which is cable-free, particularly in the unassembled state, and a cable connection part 22, in which the one or more ren lines 10 for the electrical connection to the drive motor 5 and the motor circuit board 8, in particular already in the unassembled state, lead from outside the drive unit 1. The "unassembled state" is the state before the drive unit 1 is assembled and in particular before the housing end part 21 and the cable connection part 22 are brought together. The term "wire-free" means that the respective component is free of electrical lines. Here, and preferably, the housing closing part 21 and the cable connection part 22 are each designed to be dimensionally stable, ie they do not deform, or at least not significantly, under the intended stress.

As mentioned, during the assembly of the drive unit 1 the housing closing part 21 can be brought together with the cable connection part 22 in an assembly movement which includes or is a movement with a radial and/or parallel component in relation to the geometric drive axis 4 . Here, and preferably, it is provided that the assembly movement is a purely radial movement in relation to the geometric drive axis 4 (Fig. 4) or a purely parallel movement in relation to the geometric drive axis 4 (Fig. 5b)) or one directed obliquely to the geometric drive axis 4 Movement (Fig. 5d)) includes or is.

The respective assembly movement is or includes in particular a linear movement, preferably a purely linear movement. In the assembled state, the housing end part 21 and the Kabelan connection part 22 are in particular secured against rotation relative to one another, which is preferably caused solely by bringing them together in the assembly movement.
