[Background technology]

[0002] A device with a movable cover for a vehicle roof is known as a so-called spoiler roof, as described, for example, in US Pat. No. 5,399,363. Designed obtain. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] German Patent Publication No. 102012106545(A1) Summary of the Invention [Problem to be solved by the invention]

[0004] It would be desirable to provide an arrangement for a vehicle roof that allows for reliable operation.It would also be desirable to provide a vehicle roof that allows for reliable operation. [Means for solving the problem]

[0005] According to at least one embodiment, an apparatus for a vehicle roof with a roof opening is presented, the apparatus comprising: a longitudinally slidable cover for closing the roof opening; A guide rail disposed on the vehicle roof; an opening / closing lever pivotable relative to the guide rail, the cover being longitudinally slidable relative to the opening / closing lever to open the roof opening; a drive carriage for pivoting the opening / closing lever, the drive carriage being guided along a guide rail so as to be slidable in a longitudinal direction; The opening / closing lever has a first connecting portion with the guide rail and a second connecting portion with the guide rail, The first connecting portion and the second connecting portion are spaced apart from each other in the longitudinal direction, and the opening / closing lever is configured to be slidable in the longitudinal direction relative to the guide rail in a stepwise manner; The first coupling part has a connecting link and a sliding pin guided in the connecting link, and the drive carriage is operatively connected to the opening / closing lever in the region of the opening / closing lever associated with the second coupling part, so that the opening / closing lever is pivoted and slidably moved relative to the guide rail. 、 A movable slider is disposed at the rear end of the opening / closing lever, and a cover carrier is slidably disposed within the movable slider. do.

[0006] The device is especially designed for so-called spoiler roofs. ,rear the rear end of the cover with the lift Therefore, first open / close lever In the opening direction The cover is rotated or pivoted. This cover is slid in the opening direction relative to the opening lever in order to at least partially open the roof opening, where the opening lever is held against the rest of the vehicle roof and is not slid in the opening direction together with the cover. The further the cover is slid backwards relative to the opening lever, the greater the force that must be held using the opening lever and the greater the vibration of the cover when the vehicle is moving. Overcoming this has long been desirable and the solution described in this application allows for improvement.

[0007] This is an example of Rear edge of cover The opening and closing lever comes with the cover. 、 Vehicle roof Other parts ofThis differs from so-called external guided sliding roofs, which are slid open relative to the vehicle body, in which the problems mentioned above do not occur. However, such a roof cannot be used as a replacement for a spoiler roof, since it is structurally completely different and, moreover, the use of a spoiler roof or an external guided roof depends on the suitability of the respective vehicle base.

[0008] The opening and closing lever of the device described in this application is in the longitudinal direction of the guide rail. Gradual Alternatively, cover The opening / closing lever can be locked with respect to the guide rail so as not to move together with the guide rail in the longitudinal direction during sliding of the cover. lift (So-called ventilation position )Ta The opening / closing lever is pivoted in order to open the opening / closing lever. The device described herein allows the opening / closing lever to slide a given distance in the opening direction before it is locked against the guide rail and the cover is slid further in the opening direction relative to the opening / closing lever. This improves the support points of the opening / closing lever and the cover on the guide rail compared to the prior art. It is possible to make the natural frequencies of the device, in particular the natural frequencies of the open cover, higher. It is possible to make the bearing force of the opening / closing lever at the end facing the guide rail smaller.

[0009] For this purpose, the opening / closing lever has two connecting parts with guide rails and spaced apart from each other. A longer support ratio can therefore be achieved with the opening / closing lever. This allows for a larger opening range. mouth width In other words, compared to conventional spoiler mechanisms, it is possible to cover of Placed relatively far back This makes it possible to do the same thing as before. In the spoiler mechanism 、 The opening / closing lever is located at only one pivot point on the guide rail. , Canada Moreover, the pivot point cannot slide longitudinally.

[0010] The first connecting portion having a connecting link and a sliding pin allows the opening / closing lever to rotate and pivot. According The connecting link is formed in the opening / closing lever. , slip Repin Is To Idle fixed Formed. Sliding pin of Formed on the opening and closing lever death, Link of Formed inside the guide rail vinegar The first connecting portion enables the connection between the opening / closing lever and the guide rail, this is simple and This can be achieved at low cost. In addition, the opening and closing lever is In A relatively long support ratio was achieved. , open The closing lever is slidable longitudinally relative to the guide rail.

[0011] The drive carriage is driven, for example, indirectly or directly, by the electric motor of the device. The drive carriage is arranged near the opening / closing lever, i.e. in particular at the rear end of the cover in the closed position. The drive carriage is slid longitudinally in order to pivot and longitudinally slide the opening / closing lever. After completion of the pivoting and sliding movements, for example, the drive carriage is locked relative to a guide rail. To close the roof opening, the drive carriage moves in the opposite direction, so that the opening / closing lever is slid forward and pivoted back, whereby the cover is closed.

The courses of the lift connection link and the drive connection link intersect at least in the closed position of the cover. The drive connection link has a course in which it first moves further away from the guide rail along the opening direction and then approaches the guide rail along the opening direction. For example, the drive connection link has a substantially horizontally extending portion and an inclined portion. This allows a so-called tolerance plateau, in which the longitudinal sliding of the drive pin does not cause the opening lever to slide or pivot.

[0019] lift The connecting link is lift The connecting links first extend in the longitudinal direction at an incline. , continued Thus, starting from the closed position, the opening / closing lever is first pivoted, and then lift Pin lift End of link On the edge The opening / closing lever is slid longitudinally until it reaches the opening.

The distance 113 is, for example, at least a quarter of the longitudinal direction X of the roof opening, but the distance 113 can be larger or smaller. For example, the distance 113 is larger than 5 cm, in particular larger than 30 cm, and is up to around 50 cm.

[0034] To the first connecting portion 111 Leave A sliding pin 115 is formed on the guide rail 108. The sliding pin 115 extends in the lateral direction Y.

[0035] The first connecting portion 111 has a connecting link 114 formed in the opening / closing lever 109. In particular, the connecting link 114 is a first connecting portion 114 of the opening / closing lever 109. Edge 131. The first opening / closing lever 109 is formed Edge 131 faces towards the windshield 104. The connecting link 114 has a course that extends in the longitudinal direction X in a substantially straight manner.

[0036] The sliding pin 115 is disposed in the connecting link 114. Therefore, the opening / closing lever 109 is supported on the guide rail 108 by means of the connecting link 114 and by means of the sliding pin 115. The support of the first connecting portion 111 is such that the opening / closing lever 109 is slidable in the longitudinal direction X. design This will be R is made possible by the connecting link 114.

Solidly It is also possible that they are connected.

[0038] lift Pin 123 is lift Connecting link 122 of You will be guided. lift The pin 123 is formed on the opening / closing lever 109 (see also FIGS. 7 and 16). lift The course 126 of the connecting link 122 is Leave A steeply rising slope toward the front, i.e., the windscreen 104 portion Equipped with End It starts with: lift The connecting link 122 extends substantially linearly in the longitudinal direction X. portion It has. lift Following the movement along the connecting link 122, starting from the closed position of the cover, lift Pin 123 Hama In the vertical direction Z Rising and continuing And in the vertical direction Z teeth Sara To motion Without any problems , is slid in the longitudinal direction X. Similarly , opening and closing lever 109 rear end 132 also has a vertical Z axis. Lifted , and then slid in the X direction.

[0039] The movement of the opening / closing lever 109 is caused by a drive carriage 110 (see also FIG. 17). In the illustrated embodiment, the drive carriage 110 is connected to another drive carriage 130. With The separate drive carriage 130 is driven by a linkage (FIG. 3). The separate drive carriage 130 is connected to the electric motor by a drive cable 139, for example a threaded cable that is resistant to tension and pressure. The drive cable 139 slides the separate drive carriage 130 in the longitudinal direction X during operation. This sliding is performed by the cover 103. but closed position The state of being located in and is transferred to the drive carriage 110 using a locking device 135 (FIG. 6). The drive carriage is also slid backwards in the longitudinal direction X. In so doing, the drive pin 125 of the drive carriage 110 moves along the drive connection link 124 of the opening / closing lever 109.

End Starting from, essentially linear Long Extends in hand direction X portion The cover pin 144 of the separate driving carriage 130 is disposed in the cover connecting link 133. Even if the cover pin 144 slides in the longitudinal direction X within a linear range, the front edge 106 does not slide significantly in the longitudinal direction X. edge 107 is Lifted In order to open the roof opening 102, the cover pin 144 is lowered by the cover connecting link 133. portion The cover pin 144 lowers the cover connecting link 133. portion , the sliding movement of the separate drive carriage 130 is transmitted to the cover carrier 140 and the cover 103 is caused to slide in the longitudinal direction X.

[0047] The locking device 135 may be configured to lock the locking mechanism by using, for example, a drive cable that is resistant to tension and pressure. Materials 138. Locking Materials 138 is fixedly connected to the drive carriage 110 and extends forward in the longitudinal direction X. Materials The locking pin 136 is used to selectively connect or disconnect the drive carriage 138 to or from another drive carriage 130 and to lock the drive carriage 138 in the longitudinal direction X with the guide rail 108. Materials 138 is, for example, a lock connection link 137 of the guide rail 108 of In order to be decoupled from the further drive carriage 130 and to be locked in the longitudinal direction X with the guide rail 108, the locking pin 136 rotates, for example, around an axis of rotation which corresponds to the longitudinal direction X. In the state in which the locking pin 136 is connected to the further drive carriage 130, the locking pin 136 is oriented in the lateral direction Y. In the state in which the locking pin 136 is locked with the guide rail 108, the locking pin 136 is oriented in the vertical direction Z.

[0048] Other embodiments of the locking device 135 are possible. Materials 138 is a fixed locking lever, and the elastic and flexible locking Materials 138 or otherwise configured.

[0049] 10 to 12 show the device 200 with the opening / closing lever 109 at least partially pushed up. rear end 132 in the vertical direction Z compared to the closed position of the cover 103 Lifted It is being done. For this purpose , the drive carriage 110 is slid in the longitudinal direction X, and the drive pin 125 is slid in the drive connection link 124. However, lift Pin 123 is lift The connecting link 122 rises steeply portion Located in .Ma However, the opening / closing lever 109 does not slide significantly in the longitudinal direction X. However, the rear of the cover 103 edge 107 is Lifted The front edge 106 of the cover 103 has not yet been moved significantly either. The cover slider 134 arranged on the cover carrier 140 and facing outward in the Y direction has not yet been moved significantly. The connecting link 114 has not yet been slid significantly relative to the sliding pin 115.

[0050] 13 to 15 show the device 200 in the open position of the cover 103. Compared to the ventilated position of FIGS. lift Pin 123 lift The drive carriage 110 is further slid backward in the longitudinal direction X until it is disposed at the end of the connecting link 122. In response, the drive pin 125 of the drive connecting link 124 rear end Therefore, the opening / closing lever 109 is slid to its maximum lift position. Lifted R 、 It is slid backwards in the longitudinal direction X. For this purpose The connecting link 114 is also slidably moved relative to the sliding pin 115 .

[0051] The opening / closing lever 109 is supported by two spaced apart first and second connectors 111, 112 in both the open and ventilating positions of the cover 103 shown, and in the closed position of the cover 103 shown. Therefore, especially in the open position, the force exerted on the device 200 via the open cover 103 is of , guide rail 108 and Bibo D105 To be sure to support This allows the cover 103 to slide rearward a relatively long distance.

[0052] In the fully open position, the connecting link 114 of the opening / closing lever is disposed in front of the cover pin 144 in the longitudinal direction X. In the fully open position, the separate driving carriage 130 is disposed behind the connecting link 114. The separate driving carriage 130 and the cover pin 144 are disposed behind the two opening / closing levers 109 in the longitudinal direction X in the fully open position. Edge131, 132. The other drive carriage 130 and cover pin 144 are connected to the sliding pin 115 in the fully open position. lift At the fully open position, the opening / closing lever 109 is disposed between the pins 123. portion 120 extends in the longitudinal direction X from back to front past another drive carriage 130 which, in the fully open position, is arranged in the lateral direction Y next to the opening / closing lever 109.

[0053] In particular, it is also possible for the opening / closing lever 109 to be formed with a rearwardly projecting portion 128, which in the open position of the cover (partially) overlaps the rear fixed roof element 129. This allows support of the cover carrier 140 relatively behind and in particular above the fixed roof element 129. Support of the cover carrier 140 as far back as possible in the longitudinal direction X, reducing the leverage on both the first and second connecting parts 111, 112 via the cover carrier 140. A rear end 132 of the opening / closing lever 109 and a rear end 134 of the cover carrier 140 are arranged at the rear end 132 of the opening / closing lever 109 and at the rear end 134 of the cover carrier 140. But that A movable slider 141 , which is slidably supported within the movable slider 141 , is disposed above the fixed roof element 129 when the cover 103 is in the open position.

[0054] Fixed roof Materials 129 is another cover, for example, placed in the roof opening 102. Fixed roof Materials 129 is part of the vehicle body minutes or vehicle roof 101 of forming and surrounding the roof opening 102 plate member The device 200 may be a fixed roof, in order to fully open the cover 103, in which the elements of the device 200 and another mechanical element are fixed to the fixed roof. Materials Don't go below 129 That's enough. In particular, the separate drive carriage 130 is configured as Approximate liftThe cover carrier 140 only advances to the extent of the connecting link 122. The movement of the cover carrier 140 causes the cover carrier 140 to slide significantly backwards, with the cover connecting link 133 being disposed very far forward on the cover carrier 140, and opens the roof opening 102 significantly.

[0055] 18 shows a schematic diagram of the force and lever ratio at the cover support points A and B when the cover 103 is open. The further back the front support point A, i.e., the cover slider 134 in particular, is located, the more the roof opening 102 can be opened. However, in order to reliably support the cover 103, a minimum distance i is required between the support points A and B. moreover, Leverage force acts because the front support point A and the rear of the cover 103 edge This is because the distance L between the front support point A and the movable slider 141 supporting the cover 103 is obviously longer than the distance k between the front support point A and the movable slider 141 supporting the cover 103. The difference between L and k creates a leverage force that becomes smaller the further the movable slider 141 is positioned rearward. portion 128 allows a reduction in the leverage, because the ratio of k to L is improved compared to an opening lever that does not protrude backwards. On the other hand, the reduced leverage allows a minimum interval i is also smaller because less force is applied overall and the cover 103 has a smaller i in In order to reduce the minimum distance i, a longitudinally extending opening / closing lever 109 is further provided, which makes it possible to support the cover 103 in front of the support point A, as will be explained in more detail below in FIG.

[0056] 19 is a schematic diagram showing the force and lever ratio at the first and second connecting parts 111, 112 when the cover 103 is open. The movable slider 141 is disposed at its rearmost end position in the longitudinal direction X and is fixed to the fixed roof 102. Materials 129. The first lever 109 on the front side of In the connecting portion 111, the distance f between the two points C and B is DecideA lever acts on the moving slider 141, where B is the point of application of the force, and C is the point of application of the force on the sliding pin 115 and the connecting link 114. Furthermore, the force to be introduced is determined by the distance 113, or e between the points C and D, where D is the second connecting part 112, lift Connecting link 122 and lift This corresponds to the point of action on pin 123 .

[0057] Point B is shifted backward with respect to point D because of the protrusion portion The further back point B is slid, the closer the open cover is to the rear. 103 from Lever 109 The force exerted on the cover area located behind point B is smaller because the leverage is smaller due to the ratio of L and k (FIG. 18). The leverage of the cover area located behind point B is thus smaller. For example, when the cover 103 is fully open, the distance between the cover slider 134 and the moving slider 141 and the distance between the cover slider 134 and the moving slider 141 are smaller. edge The ratio of the length of the cover 103 between the second connecting part 112 and the second connecting part 113 is greater than 0.25, in particular greater than 0.28 or greater than 0.3. Also possible is a ratio at which the acting force of the moving slider 141 is as small as possible. For example, the bearing ratio e:f is as large as possible in order to keep the acting force at the second connecting part 112 as small as possible.

[0058] The force to be absorbed by the opening / closing lever 109 depends in particular on the ratio f:e. The smaller the ratio f:e, the more evenly the force to be absorbed by the opening / closing lever 109 is distributed to the application points C and D. The closer the ratio f:e is to, for example, a value of 1.0, the more evenly the force to be absorbed by the opening / closing lever 109 is distributed to the application points C and D. Protrusion portion The further forward the first connector 111 is positioned, the smaller the force that has to be absorbed at point D, with the length of 128 kept constant. The larger the distance 113, or e between points C and D, the smaller the force that has to be absorbed at point D, with the distance between points D and B in the longitudinal direction X kept constant.

[0059] The forces to be absorbed at points A and D are portion 128, the action point B of the movable slider 141 is moved backward, so that the opening / closing lever 109 is extended vertically. portion It can also be reduced by positioning the first link 111 relatively far forward using 120.

[0060] By using the connecting links 114 or 122 and 124 to realize not only the first connecting portion 111 but also the second connecting portion 112, the desired opening can be achieved. mouth width And based on the achievable force ratios, flexible design of individual lengths and extensions is possible.

[0061] The support ratio of the opening / closing lever 109 is mouth width It is possible to achieve like The adjustment is reliable. The support point B of the moving slider 141 for supporting the cover carrier 140 is moved backward. The opening / closing lever 109 is supported at two support points, the first connecting part 111 and the second connecting part 112. The support point on the front side of the first connecting part 111 is connected to the connecting link 11 in the opening / closing lever 109. 4、 and is supported on a sliding pin 115 fixed to the guide rail 108. This allows the rotational movement of the opening / closing lever 109 to be acted on via an advantageously selected connecting link guide, which gives the moving slider 141 an additional stroke and results in a relatively large support ratio for the opening / closing lever 109.

[0062] The support ratio due to positions B and C acting on the cover carrier 140 and the opening / closing lever 109 in the longitudinal direction at the normal position D is mouth width The maximum supporting force acting on the point of application D is, for example, equivalent to a conventional machine, in which the opening and closing lever is moved perpendicular to the vertical direction Z and in particular backwards when the roof is open. Materials129. For example, a force acts on the application point D that is less than 10% greater, for example 6% to 9% greater, than the force acting on the point B of the moving slider 141. Of course, other force ratios are also possible. For example, the length f is about 440 mm and the length e is about 400 mm. For example, the difference between the length e and the length f is greater than 10 mm and less than 50 mm.

[0063] Opening and closing lever 109 drive Movement is by means of the drive carriage 110 and by means of the locking device 135 by means of another drive carriage 130 Against For this purpose, the drive carriage 110 includes: 、 Drive pin 125 formation The drive pin runs within a drive connection link 124 in the opening / closing lever 109. The drive connection link 124 is lift The drive carriage 110 is formed as a cross link to the connecting link 122. In addition, the drive connecting link 124 has flats to adjust the tolerances for the closed and ventilated positions. Furthermore, any transmission ratio can be implemented using the drive connecting link 124. The connection or locking between the drive carriage 110 and the further drive carriage 130 or the guide rail 108 is achieved, for example, by using a locking pin 136 rotatable about a longitudinal axis or another locking device.

[0064] The front edge 106 of the cover 103 mechanism This allows a second control connection link to be formed in the cover carrier 140. There is no need to set . One Slider 134 Only , Cover Carrier 140 Used in , this cover carrier is , on cover 103 Significantly before To In particular, the cover 103 is disposed as close as possible to the imaginary rotation axis of the cover 103. This allows a large opening in the longitudinal direction X. mouth width In addition, it saves space. Noro The locking device 135 allows the roof opening 102 to have a large opening width and a smooth locking operation with less noise. The number of components is smaller than that of other conventional models. mechanism1. This reduces the complexity and allows the device 200 to be realized at low cost. Overall, a large natural frequency is achieved when the cover 103 is open. At the rear support point of the second connection 112 of the opening / closing lever 109, a low support force can be achieved due to the longer support ratio of the opening / closing lever 109.

[0065] The vehicle roof closes the roof opening 102. of bar Only one That is, only the movable cover 103 A vehicle roof 101 having It is possible to achieve this because parts A, fixed roof Materials 129.

[0066] Connecting link 114, lift The implementation using the connecting link 122 and the drive connecting link 124 allows for a large degree of design freedom and a sufficient margin of error. Overall, the device 200 can be realized with a relatively small number of components. The device 200 allows for reliable opening and closing of the roof opening 102. [Explanation of symbols]
