Description

Drive system for a flow guide roof system of a motor vehicle

Technical Field

The invention relates to a drive system for a flow guide roof system of a motor vehicle, comprising a support strip which can be connected to a movable roof part; with a control mechanism engaged at the support bar for displacement of the support bar between a closed position, a vented position and an open position; and a guide rail arrangement is provided, in which the control mechanism is guided so as to be longitudinally movable, wherein the control mechanism has a rear actuating lever, which is connected to the support bar by means of a control slide and is mounted so as to be pivotable between a rest position and an active position. The invention further relates to a flow guide roof system for a motor vehicle having a drive system of this type.

Background

DE 102017207893 a1 discloses a guide roof system for passenger vehicles, which has a movable roof part. The movable lid member is movably supported between a closed position closing the lid section, an inclined vent position and an open position opening the lid section. In order to be able to drive the roof part into the desired position, the roof part is assigned two drive systems on opposite sides, which are designed identically to one another in terms of function and are driven synchronously with one another by means of an intermediate electric drive motor. Each drive system has a support bar laterally secured at the movable top cover member. In order to displace the supporting strip in a positively guided manner, a control mechanism is provided, which engages on the supporting strip and is guided in a guide rail arrangement, to which the cover is fixed, in a longitudinally displaceable manner. The control mechanism has a rear actuating lever which is mounted in a stationary manner in the base of the rail arrangement in a pivotable manner and which is articulated at its upper end region in a pivotable manner on a control slide which surrounds the web guide of the supporting web in a slidable manner. The lower swivel bearing of the movable lever projects downward beyond the bottom of the guide rail arrangement.

Disclosure of Invention

The task of the invention is that: a drive system and a flow dome system of the type mentioned at the outset are achieved, which require a reduced structural height.

For the drive system, this task is solved by: the movable lever is mounted so as to be able to pivot on a control slide which can be moved in the longitudinal direction of the guide rail arrangement, and is assigned a mechanical positive control which displaces the movable lever between a rest position and an active position as a function of the movement of the control slide. In contrast to the prior art, the guide rail arrangement does not require a space for the pivot bearing of the movable lever underneath. The drive system is arranged in a flow guide roof system of a passenger vehicle. The drive system according to the invention is attached to the side of the movable roof part of the guide roof system. The other drive system is slaved to the opposite side of the movable roof part. The two drive systems are mirror-symmetrically designed relative to a vertical vehicle center longitudinal plane, but otherwise are identical to one another. The opposing drive systems are driven synchronously with one another by means of an electric drive unit and respective drive transmission systems, preferably in the form of threaded pitch cables or flexible toothed racks, in order to achieve the desired parallel displacement of the movable roof parts.

In the design of the invention, provision is made for: the mechanical positive control has a stationary control contour in the rear region of the guide rail arrangement and a control pin arranged on the movable lever, which interact in a complementary manner in such a way that the movable lever is positively guided in the upward or downward direction depending on the direction of travel of the control slide.

In a further embodiment of the invention, the movable lever is guided in a force-fit manner in a rearward direction into its rest position and in a force-fit manner in a forward direction into its active position, relative to the orientation of the guide rail arrangement. In contrast to the prior art, the movable lever in its rest position pivots back and down at the control slide. In order to be transferred into its active position, the movable lever is pivoted forward and upward until the movable lever is oriented at least largely in the vertical direction. The corresponding pivoting movement of the movable lever is effected in a positively guided manner by the driving movement of the control slide and the insertion of the control pin of the movable lever into the stationary control contour.

In a further embodiment of the invention, the control contour is designed as an arcuate control groove in a control member fastened to the rail arrangement. The arcuate control slot is arranged laterally to the path of travel of the control slide and of the movable lever, and the control pin projects horizontally with a side facing the control slot with reference to a vertical plane of oscillation of the movable lever. In an advantageous manner, the plane of oscillation of the movable bar is oriented in the vertical direction and in the longitudinal direction of the rail device with reference to the coordinate system of the rail device. With such an orientation, the control pin protrudes from the movable lever in a lateral direction toward the control slot. The arcuate control groove is open at the front end in the longitudinal direction of the guide rail arrangement in order to be able to achieve a defined insertion of the control pin of the activation lever into the front end region during the driving movement of the control slide.

In a further embodiment of the invention, the control groove forms a front-lower and a top-rear arch, as seen in the longitudinal direction of the guide rail arrangement. The arch is thus bent back and upward in an arcuate manner continuously from the front, lower front end region. The control pin is held in the control groove as long as the control slide is in the rear functional end position.

In a further embodiment of the invention, the control slot is open in the transverse direction of the guide rail arrangement toward the middle of the guide rail arrangement, and the control slot is matched in its dimensions complementarily to the control pin of the actuating lever in such a way that the control pin is guided in a linearly movable manner along the curve defined by the arch. In addition, the lower, front end region of the control groove is open in the longitudinal direction of the guide rail arrangement in order to be able to cause the insertion of the control pin upon a corresponding rearward travel movement of the control slide and thus to block the control pin.

In a further embodiment of the invention, the control element is designed as a one-piece plastic element. The control member is fixedly connected to the rail arrangement. For this purpose, receiving and holding areas are preferably provided in the side walls and/or the bottom wall of the rail arrangement.

The object on which the invention is based is achieved for a flow dome system by providing at least one drive system according to the embodiments described above.

Detailed Description

The air guide roof system 1 according to fig. 1 is provided for the roof area of a passenger vehicle. The vehicle body of the passenger vehicle is punched out in the roof region in order to be able to insert and fasten the air guide roof system 1. The air guide roof system 1 has a movable, dimensionally stable roof part 2 which is provided to cover an open region of the air guide roof system 1, which is not illustrated in detail. The flow-through roof system 1 is preassembled as a separate roof module. For this purpose, a support frame 3 is provided, which has a fixed, dimensionally stable head section 4 in the rear region and a front cover 5 in the front region, which is likewise firmly connected to the support frame 3. Below the front cover 5, a central electric drive unit is provided at the support frame 3, which drives two drive systems by means of respective drive trains, which are assigned to opposite longitudinal sides of the support frame 3 and which serve to displace the movable cover part 2 synchronously between the closed position, the ventilation position shown in fig. 1 and the open position. In the illustrated embodiment, a flexible, threaded pitch cable is provided as a drive transmission train which can be displaced linearly movably in opposite directions by means of a suitable transmission mechanism via an intermediate electric drive unit. The two opposing drive systems for synchronously displacing the movable cover part 2 are designed identical to one another in terms of function. In the following, the drive system 6 on the left, viewed in the normal driving direction of the passenger car, is explained according to fig. 2 to 12. The embodiment of the drive system shown is applicable in the same way to an opposite, not shown drive system. In its open position, the movable cover part 2 travels rearward over the fixed top end section 4 and projects largely freely rearward above this top end section 4.

The drive system 6 has a support strip 7 which extends in the assembled state in the longitudinal direction of the vehicle and is shown as a strip profile which is oriented substantially vertically. In the ready-to-assemble state, the support bar 7 is fastened in the region of the underside of the movable roof part 2 by means of a screw connection to the lateral support and is thus firmly connected to the movable roof part. In its lower region, the support strip has a rectangular tab guide 13 which projects outwards and extends over the majority of the length of the support strip 7. The web guide 13 is integrally formed from the supporting web 7 by cold forming. In the front region, the supporting bar 7 is provided with

control cams

11, 12, 14 projecting outward in the transverse direction of the vehicle, wherein the two control cams 11 and 14 interact with a control slide, not shown in detail, of a drive slide 9 which can be moved in a longitudinally movable manner in the guide rail arrangement 8. The drive transmission system described above is connected to the drive carriage 9, so that the travel movement of the control carriage 9 along the guide rail arrangement 8 is necessarily achieved when the drive transmission system is moved linearly by activating the central electric drive unit. The control slide of the drive slide 9 is connected to the control cams 11, 14 for: during the driving movement of the drive carriage 9, the support bar 7 is moved and additionally the support bar 7 is displaced in the vertical direction. The front double guide cam 12 is provided for: on the one hand, the vehicle can travel along a curve section (not shown in detail) on the front side of the guide rail arrangement 8 and, on the other hand, over a guide track of the guide rail arrangement 8 extending in the longitudinal direction of the vehicle. The guide rail arrangement 8 is part of the support frame 3 of the guide roof system 1 and is therefore firmly connected to the support frame 3.

The rear region of the support bar 7 is supported by a rear actuating lever 15. The actuating lever 15 is mounted on the control slide 19 so as to be able to pivot about a pivot bearing 26 by means of a lower pivot bearing 17. The movable lever 15 is mounted so as to be able to pivot in a vertical vehicle longitudinal plane in the ready-to-assemble state. This corresponds to a longitudinal plane of the rail arrangement 8, which extends in the vertical direction and the longitudinal direction of the orientation of the rail arrangement 8. The movable lever 15 has an upper pivot bearing point 16, which is spaced apart from a lower pivot bearing point 17 and is arranged at the end region of the movable lever 15 opposite the lower pivot bearing point 17. The actuating lever 15 is mounted so as to be pivotable by means of the upper pivot bearing 16 on the control slide 10, which surrounds the web guide 13 so as to be linearly movable in the longitudinal direction of the supporting web 7. The supporting bar 7 can therefore be displaced in the control slide 10 by means of its web guide 13. The web guide 13 has a curvature to the extent that, as can be seen well in fig. 8 at the right-hand rear region of the support bar 7, the control slide 10, due to its pivotable mobility relative to the movable lever 15, follows this curvature by a corresponding tilting movement about its pivot axis.

The control slide 19 is guided in a linear manner in a corresponding guide track of the guide rail arrangement 8 by means of a slide body, which is not illustrated in detail. A coupling rod 20, which extends forward toward the drive slide 9, engages at the control slide 19 and can be positively connected by means of a coupling mechanism 21 either to a receptacle 24 of the drive slide 9 or to a support 22 of the guide rail arrangement 8. The holder 22 is positioned in a stationary manner relative to the guide rail arrangement 8 in the front region of the guide rail arrangement 8. The coupling rod 20 comprises a coupling means 21 which can be displaced in a longitudinally movable manner in a guide track, not shown in detail, of the guide rail arrangement 8. Depending on whether the coupling means 21 is releasably connected to the receptacle 24 of the drive carriage 9 or to the bracket 22, the coupling rod 20 is connected in a positionally fixed manner to the guide rail arrangement 8 or firmly to the drive carriage 9. In the case of a stationary coupling link 20, the control slide 19 of the rear actuating lever 15, which is firmly connected to the coupling link 20, is also necessarily positioned in a stationary manner in the guide rail arrangement 8 by means of the coupling mechanism 21. When the coupling means 21 are coupled to the receptacle 24 of the drive slide 9, the coupling means are then inevitably carried along during the displacement movement of the drive slide 9 and therefore also the control slide 19 in the respectively same direction.

As can be seen from fig. 8 and 9 and fig. 10 to 12: with reference to the functional orientation of the guide rail arrangement 8 in the support frame 3 of the guide roof system 1, the movable lever 15 is pivoted back and down in its lower rest position. In this rest position, the pivot lever 15 therefore extends about its lower pivot bearing point 17 largely in the region of the pivot bearing 26 rearward in the longitudinal direction and horizontally to some extent. As can be seen from fig. 11: the movable lever 15 is inclined upwards at a small angle in this rest position. Since the control slide 10 rests on the control slide 19 in the rest position of the movable lever 15, the movable lever 15 is held in this rest position in a stable manner.

As can be seen from fig. 9: the movable lever 15 is assigned a stationary control member 25 which is provided with an arcuate control slot 27. The control members 25 are fastened at the respective wall sections of the rail arrangement 8. The arcuate control groove 27 is formed in the plastic control component 25 as a control groove which opens in the transverse direction inwardly toward the center of the guide rail arrangement 8 and which, in addition, opens at the front end region 28 in the longitudinal direction of the guide rail arrangement 8. The control groove 27 has an at least largely rectangular free cross section. The free cross section of the control groove 27 is adapted to the dimensions of the control pin 18, which is firmly connected to the actuating lever 15 and projects from the actuating lever 15 in the transverse direction, i.e. parallel to the respective pivot axes of the lower pivot bearing 17 and of the upper pivot bearing 16. The control pin 18 is positioned at the activation lever 15 in such a way that, when the control slide 19 travels backwards in the longitudinal direction of the guide rail arrangement 8, the control pin 18 in the rest position of the activation lever 15 is inevitably inserted into a front end opening 28 on the front side of the control groove 27 of the control member 25. Since the free cross section of the control groove 27 is adapted to the dimensions of the control pin 18, the control pin 18 is guided in a linearly movable manner in the control groove 27. In the exemplary embodiment shown, the control pin 18 is of cylindrical design. The control groove 27 constitutes a mechanical positive control for the control pin 18 and thus for the movable lever 15.

During the driving movement of the control slide 19, either during initial start-up or during normal operating functions, the control pin 18 is inserted backwards into the control groove 27 of the control member 25 and is guided backwards and upwards along the arcuate guide. The movable lever 15 is thereby necessarily erected until it remains in the end position according to fig. 12. In this case, the control pin 18 enters a likewise open front end region above the control groove 27. As can be gathered from fig. 12: in this position, too, the control pin 18 remains engaged in the control groove 27, so that the movable lever 15 is supported in a stable and fixed manner in this continuously movable position. The control pin 18 is mounted in the control groove 27 in a sliding manner without play, so that a linear guidance of the control pin 18 takes place in the longitudinal direction of the arcuate guide of the control groove 27.

When the coupling rod 20 is coupled to the drive slide 9 via the coupling mechanism 21, the control slide 19 is carried along in the longitudinal direction of the guide rail arrangement 8 via the coupling rod 20.

The way in which the drive system 6 functions is explained below.

Starting from the closed position according to fig. 2 and 5, the drive carriage 9 travels back in the longitudinal direction of the guide rail arrangement 8 from a starting position on the front side by means of a drive transmission and a central electric drive unit. The coupling rod 20 is coupled to the drive slide 9 via the coupling means 21. The double guide cam 12 of the front side of the support bar 7 slides obliquely upward and rearward along the arc-shaped guide rail of the front side. At the same time, the obliquely extending control slide in the drive slide 9 results in: the control cams 11 and 14 of the support bar 7 likewise move upwards. Since the drive slide 9 is coupled to the control slide 19 via the coupling rod 20, the control slide 19 also runs backwards, as a result of which the control pin 18 is displaced backwards and upwards in the control groove 27. As a result, the movable lever 15 is necessarily moved at least to a large extent in the vertical direction upwards (fig. 12), as a result of which the rear parts of the supporting bar 7 are lifted into the ventilation position. The other, slight backward travel movement of the drive slide 9 results in: the coupling means 21 are pressed into the brackets 22 of the rail arrangement 8. The bracket 22 is a plastic component which is fastened in a recess 23 in the side wall of the rail arrangement 8. The coupling means 21 is thereby fixed in a stationary manner to the guide rail arrangement 8, whereby the control slide 19 is also fixed in a stationary manner relative to the guide rail arrangement 8 due to the connection by the coupling rod 20. The coupling rod 20 and the coupling means 21 remain in this fixed position, while the drive slide 9 travels further backwards. In this case, the double guide cam 12, which runs upward along the inclined curved guide rail at the front end of the guide rail arrangement 8, together with the control cams 11 and 14 and the control slide in the drive slide 9, lifts the supporting bar 7 upward also with its front region. The control cam 14 is held in the control slide of the drive slide 9 during the further travel movement of the drive slide 9, while the rear control cam 11 projects freely upward above the drive slide 9. The front region of the supporting strip 7 therefore remains also positively coupled to the drive carriage 9, so that a further rearward travel movement of the drive carriage 9 necessarily also drives the supporting strip 7 rearward. Since the actuating lever 15 is blocked in a fixed position in the actuating position, the web guide 13 slides through the control slide 10 until the open position according to fig. 4 and 7 results. As can be gathered from fig. 12, in this open position the drive slide 9 rests against the control slide 19.

If the movable cover part is to be returned from this open position into its closed position again, the drive slide 9 is driven in the respectively opposite longitudinal direction. As soon as the drive slide 9 has reached the coupling means 21 again, the drive slide 9 drives the coupling means 21 again via the following ramp in the region of the receptacle 24, as a result of which the coupling means 21 is necessarily moved away again from the support 22 in the transverse direction inward. By bringing the coupling means 21 along with the drive slide 9, the control slide 19 is also pulled forward again, whereby the control pin 18 slides down again and forward in the control groove 27 and necessarily brings the movable lever 15 back into its rest position again.

In the exemplary embodiment shown, the path of the control slide 19, through which the control slide 19 passes before the coupling means 21 is fixed in the stationary holder 22, is designed to be so small that the control pin 18 is permanently held in the control groove 27 of the control member 25. The path followed by the control slide 19 therefore corresponds to the path followed by the drive slide 9 from its front end position up to an intermediate position in which the coupling means 21 are transferred to the stationary support 22. This design has the following advantages: the front end region 28 of the control groove 27 does not have to be used as a receiving opening in order to catch and receive the control pin 18 during the rearward travel movement of the control slide 19.
