Description

The present invention relates to a stop arrangement for a variable-position element on a vehicle body with the variable-position element, the vehicle body and a stop element.

A motor vehicle usually has a body on which a movable body element, such as a tailgate, is attached. The tailgate is usually connected to the body in an articulated manner via two hinges. Furthermore, the tailgate is locked in its closed state in a locking device and is flush with adjacent bodywork elements. In the closed state of the tailgate, the tailgate generally rests on at least two stop buffers. A bump stop can be attached to the tailgate or to the body itself and is often designed in such a way that it is adjustable in height so that the closing comfort of the tailgate can be adjusted and the tailgate in the closed state rests against the stop buffers and in is biased to the locked state. Such a stop buffer is usually designed to be elastically deformable within certain limits. In this case, when the tailgate is closed, the stop buffer is elastically deformed and applies a pretension to the tailgate.

Such a bump stop can be attached to the tailgate or the body in various ways. For example, in the DE 10 2006 017 141 A1 shown a bump stop consisting of a cylindrical body and the outer periphery of which is formed with an external thread which can be screwed into a suitable hole in the vehicle body or in the lid.

Another way of attaching such a buffer or stop is in the DE 10 2007 051 103 A1 shown. In particular, a height-adjustable buffer 2 is shown there, which has a foot that can be pressed into a hole in a tailgate or body and can be fixed to the hole in the manner of a snap connection.

Also in the DE 10 2009 022 809 A1 an adjustable stop buffer is shown which can be fastened in an opening of a vehicle body or an element whose position can be changed by means of elastically deformable latching elements.

In addition, bump stops are known which can be fastened to an opening in a tailgate or a vehicle body in the manner of a bayonet catch, ie a plug-and-turn connection EP 0 892 140 known.

It is now the object of the present invention to create a stop arrangement for a variable-position element on a vehicle body with a stop element, positioning and attachment of the stop element on the variable-position element or the vehicle body being improved. Furthermore, it is the object of the invention to create a stop element which is suitable for such a stop arrangement and a motor vehicle which has such a stop arrangement.

This object is achieved by a stop arrangement having the features of patent claim 1.

Developments of the invention are described in the dependent patent claims.

In particular, a stop assembly according to the present invention has a variable-position element on a vehicle body, the vehicle body and a stop element, which has a plug-and-rotate connection with the variable-position element or with the vehicle body can be connected. The plug-and-turn connection also has

Means that bring about a radial clamping of the stop element, the means being formed by a plug-and-rotate connection projection of the stop element and a receiving opening in the variable-position element or the vehicle body for receiving the plug-and-rotate connection projection, and the plug-and-rotate connection projection has a flange has for reaching behind the edge of the receiving opening.

The variable position element can be a body flap. A body flap is preferably a tailgate or a front flap. The vehicle body can preferably be a motor vehicle body. A plug-and-turn connection is in particular a connection in which a connection is made via a plug-in process and a subsequent turning process. An example of such a plug-and-turn connection is a so-called bayonet lock. A radial clamping refers to a clamping direction that is perpendicular to a longitudinal axis of the stop element. An axial direction of the stopper is basically a direction in which a stopper acts, that is, a direction substantially perpendicular to the positionable member and/or the vehicle body. Radial clamping according to the present invention can also mean that clamping takes place in the direction of a plane of the variable-position element or the vehicle body.

According to a further development of the present invention, the means mentioned are designed in such a way that the radial clamping has a radially centering effect on the stop element.

Radially centering according to the present invention means that the stop element is positioned in a radially centering manner as a result of the insertion and turning process, in particular the turning process.

According to the present invention, the mentioned means are formed by a plug-and-turn connection projection of the stop element and a receiving opening of the variable-position element or a receiving opening of the vehicle body for receiving the plug-and-turn connection projection. In other words, the receiving hole is formed in the positionable part or the vehicle body, and the plug-and-turn connection projection can be inserted into the receiving hole. In particular, the funds are designed such that the The plug-and-turn connection projection can first be inserted into the receiving opening and can then be rotated in a specific angular range until the radial clamping of the stop element takes effect.

In the stop arrangement with the plug-and-turn connection projection and the receiving opening, a clamping section of an outer circumference of the plug-and-turn connection projection and at least one associated clamping section of an inner circumference of the receiving opening are preferably formed at least partially with a radial oversize in relation to one another.

This means that, at least on the clamping section, the outer circumference of the plug-and-turn connection projection is at least partially larger than an inner circumference of the receiving opening on the associated clamping section in the receiving opening.

The radial clamping is easy to produce due to the radial oversize.

In the stop arrangement according to the present invention, the clamping section of the outer circumference of the plug-and-turn connection projection and/or the associated clamping section of the inner circumference of the receiving opening is preferably formed eccentrically in relation to a common longitudinal axis of the receiving opening and the plug-and-turn connection projection, that with a rotation of the plug-and-turn connection projection, an increasing fastening force acts.

In other words, at the clamping section of the outer circumference and the associated clamping section of the inner circumference, a radial excess increases progressively with increasing rotation, as a result of which a progressively higher fastening force or clamping force can act. This makes it particularly easy to produce a radial attachment or clamping.

In the case of the stop arrangement, the clamping section of the outer circumference of the plug-and-turn connection projection can preferably be Circumference and/or the associated clamping section of the inner circumference - have ribs which are arranged in such a way that ribs and valleys, areas between the ribs, form in the radial direction, i.e. transversely to the direction of rotation of the plug-and-turn connection projection in the radial direction, alternate, the ribs being in particular elastically and/or plastically deformable.

Ribs have the advantage that they can be elastically or plastically deformed more easily than a continuous surface. A better clamping effect is thus possible. Furthermore, a larger angle of rotation of the plug-and-turn connection projection is possible until the desired clamping force is reached.

In the case of the stop arrangement with the clamping section of the outer circumference and the associated clamping section of the inner circumference, the plug-and-turn connection projection with a plurality of clamping sections, e.g. B. two, three or four clamping sections, wherein the plurality of clamping sections are arranged in particular symmetrically on the circumference of the plug-and-turn connection projection and the receiving opening has the same number of associated clamping sections of the inner circumference.

A radial centering effect can be produced particularly easily with a plurality of clamping sections, in particular when the plurality of clamping sections are arranged essentially symmetrically on the circumference of the plug-and-turn connection projection.

In the case of the stop arrangement according to the invention with the plug-and-turn connection projection, the plug-and-turn connection projection also has a flange for gripping behind the edge of the receiving opening. In particular, the flange can bring about an axial fixation, in particular an axial clamping, of the stop element.

Preferably, in the striker assembly according to the present invention, the plug-and-turn connection projection has a surface opposite the flange for abutting an edge of the receiving opening.

Accordingly, the stop element can be held in the axial direction by the flange and the opposite surface of the plug-and-turn connection projection, between which the edge of the receiving opening is arranged. The flange and the opposite surface can be designed in such a way that the edge of the receiving opening is clamped between the flange and the opposite surface, in particular when the plug-and-turn connection projection is rotated.

The opposing surface may be continuous or may have discontinuities.

The edge of the receiving opening preferably has a recess for the passage of the flange.

According to a development of the stop arrangement according to the present invention, the plug-and-turn connection projection can be made of plastic.

As a result, the plug-and-turn connection projection can be easily manufactured, there is no problem of corrosion between the plug-and-turn connection projection and the positionable member or the vehicle body, and a clamping effect can be achieved even with a small torque. Preferably, in the stop assembly according to the present invention, the stop member has an adjustable stop member.

With this, the height of the stop element and thus the position of the variable-position element in the stop position can be fixed.

The stop element of the stop arrangement according to the present invention can also be provided with an elastically deformable area which is deformable in particular in the axial direction of the stop element.

As a result, a transfer of the variable-position element into the stop position can be dampened. Furthermore, a certain prestressing of the variable-position element in the stop position can thus be realized.

Furthermore, in the case of the stop arrangement according to the present invention, the stop element can be inserted into a receiving opening of the variable-position element or the vehicle body and can be fixed by subsequent rotation. In the stop arrangement according to the present invention, the variable-position element is preferably connected to the vehicle body via at least one hinge and can be locked or at least snapped into a stop position with a locking device.

The following is a description of the embodiments according to the present invention with reference to the figures.

A first embodiment is based on the Figures 1 to 3 explained.

In figure 1 a stop arrangement 1 is shown, in which a tailgate 3, ie a variable-position element according to the present invention, is in a stop position 11 relative to a vehicle body 5. The stop position 11 is defined by a stop element 7 which is connected to the vehicle body 5 via a plug-and-turn connection 9 .

The plug-and-turn connection 9 is formed in particular by a plug-and-turn connection projection 13 of the stop element 7 and a receiving opening 15 of the vehicle body 5 . The plug-and-turn connection projection 13 has a flange 23 which engages behind an edge of the receiving opening 15 . The plug-and-turn connection projection 13 is held in a form-fitting manner in the axial direction by the flange 23 and a surface 21 opposite the flange 23 .

In figure 2 is a section through the stop assembly 1 along the body plane AA in figure 1 shown. In particular, in figure 2 shown how the plug-and-turn connection projection 13 is radially clamped in the receiving hole 15 . As a result, the plug-and-turn connection projection 13 is held in a form-fitting manner in the radial direction. Furthermore, the plug-and-turn connection projection 13 is held at least by friction in the axial direction due to the radial clamping.

The receiving hole 15 has four clamping sections 19 on the inner circumference of the receiving opening 15. Opposite clamping sections 19 are each identical in design, with adjacent clamping sections 19 being different from one another. However, all four clamping sections can also be designed in the same way. It would also be possible z. B. form only three equal terminal sections. The clamping sections 19 are formed eccentrically in relation to the central axis or longitudinal axis of the receiving opening 15 or the plug-and-rotate connection projection 13 .

Furthermore, the plug-and-turn connection projection 13 has four clamping sections 17 which are associated with the clamping sections 19 or are formed opposite. The clamping sections 19 and 17 are formed symmetrically to the longitudinal axis of the plug-and-turn connection projection 13 and the receiving opening 15, respectively.

The clamping sections 17 on the circumference of the plug-and-turn connection projection 13 are designed in the form of ribs 171 running transversely to the plane of section, between which ribs 172 extend. In particular, each clamping section 17 has three ribs 171 . A connecting line of the front ends of the ribs 171 is in an eccentric shape, i. H. formed eccentrically with respect to the longitudinal axis of the plug-and-turn connection projection 13 . In other words, each clamping portion 17 has an eccentric surface through which valleys run substantially parallel to the longitudinal axis. Due to their geometry, the ribs 171 can be elastically deformed when the plug-and-rotate connection projection 13 is rotated and enable a particularly good clamping effect.

In figure 2 the stop element 7 or the plug-and-turn connection projection 13 is shown in a state in which it is inserted into the receiving opening 15 and rotated by the greatest possible angle relative to the receiving opening 15 so that a desired clamping force is achieved. In other words is in figure 2 the state is shown in which the stop element 7 is completely fixed to the vehicle body 5 or is clamped to it. In particular, a self-centering radial clamping is shown, the radially acting centering being formed in particular by the symmetrically arranged clamping sections 17 and 19 and their eccentric effect. The eccentric clamping portions 17 and 19 are each twisted to an interference fit and clamped to each other. In the process, an elastic and/or plastic deformation of the ribs 171 takes place, in particular in the direction of rotation.

The described stop arrangement allows the stop element 7 to be mounted on the vehicle body 5 from one side or alternatively on the tailgate 3 . In particular, the stop element 7 can be positioned particularly precisely in relation to the radial position since, as described, the clamping connection has a radially centering effect. Furthermore, since the connection is designed as a radial clamp, it is not possible to displace the stop element 7 in a radial direction. In addition, the radial clamping also acts at least in a non-positive manner in the axial direction. As a result, tolerance requirements for the axial positive mounting by the flange 23 and the opposite surface 21 can be reduced.

The stop element 7 and in particular the plug-and-turn connection projection 13 are made of plastic, while the vehicle body is formed by sheet metal.

In addition to the radial clamping described above, the push-pull connection 9 also has an axial clamping, which is formed by the flange 23 and the opposite surface 21 . The opposite surface 21 of the plug-and-turn connection projection 13 is used to rest on the vehicle body 5, in particular the edge of the receiving opening 15. The flange 23 engages behind the edge of the receiving opening 15. The edge of the receiving opening 15 also has four recesses 25, the one Allow passage of the flange 23 and also the clamping sections 17 when the plug-and-turn connection projection 13 is inserted into the receiving opening 15 . During the step of turning the plug-and-turn connection projection 13, the flange 23 can then engage behind the edge of the receiving opening 15, so that the effect is achieved in a manner similar to a bayonet lock. Furthermore, the plug-and-turn connection projection 13 has two stopper parts 27 which are each accommodated in one of two opposing recesses 25 and limit a rotation angle of the plug-and-turn connection projection 13 .

Since the stop assembly according to the first embodiment of the present invention has not only an axial clamping, but also a very effective radial clamping of the plug-and-turn connection projection 13 on the Receiving opening 15, a requirement for the accuracy of a height of the receiving opening 15 is significantly reduced, as already explained above.

In this way, the plug-and-turn connection projection can also be easily mounted on a receiving opening stamped in a body panel, the dimensional accuracy of which is lower.

In figure 3 Incidentally, a state is shown in which the plug-twist connecting projection 13 is plugged into the receiving hole 15 but is not yet twisted.

A stopper assembly according to a second embodiment of the present invention will be described below, with description of features common to the first embodiment being omitted. The second embodiment is not shown in the figures.

In contrast to the first exemplary embodiment, clamping surfaces of a receiving opening are not designed eccentrically in the second exemplary embodiment. Only clamping surfaces of the plug-and-turn connection projection are designed eccentrically. Similar to the first embodiment, the clamping surfaces of the plug-turn connection projection are formed by ribs that run in the longitudinal direction of the plug-turn connection projection and are elastically and/or plastically deformable when the stop element with the plug-turn connection projection is rotated in the clamping direction becomes.

In the same way as in the first exemplary embodiment, the plug-and-turn connection of the second exemplary embodiment has a radially centering effect and the plug-and-turn connection projection cannot be displaced radially when the stop element is fully assembled.

The first and second embodiments described above each have four pairings of clamping surfaces - one pairing being formed by a clamping surface of the receiving opening and a corresponding clamping surface of the push-pull connection boss formed - trained. In a modification of these exemplary embodiments, three or five pairs of clamping surfaces can also be provided as an alternative. An alternative with two pairs of clamping surfaces is also conceivable.

Furthermore, the clamping surfaces of the plug-and-turn connection projection are formed with ribs. Alternatively, however, these clamping surfaces can also be designed similarly to the clamping surfaces shown on the receiving opening without ribs.

Furthermore, it is conceivable that the clamping surfaces of the plug-and-turn connection projection are not formed eccentrically, whereas the clamping surfaces of the receiving opening are formed eccentrically.

Finally, any configuration of clamping surfaces is possible, provided that a pair of clamping surfaces enables radial clamping when the plug-and-rotate connection projection rotates.

The plug-and-turn connection projection of the present exemplary embodiments is made of plastic, whereas the vehicle body, or the part of the vehicle body to which the stop element is attached, is made of sheet metal. Of course, the plug-and-turn connection projection can also consist of a metallic material and the vehicle body can also consist of a plastic or a fiber-reinforced plastic.

In order to be able to mount the same stop element with the same plug-and-turn connection projection at different interfaces in the vehicle body or in a body flap, the height of the receiving hole should be approximately the same. In order to be able to do this with different sheet metal thicknesses, it is conceivable to emboss a sheet of metal to the desired standard height in the area of the receiving opening. Since such an embossing can only take place within a certain range of accuracy, ie the height of the receiving hole is then subject to fluctuations within a certain tolerance range, the present invention is particularly advantageous since it not only provides axial clamping but in particular fixed radial clamping of the stop element or plug-and-turn connection projection allows. As a result, the requirements for axial clamping are significantly lower while the durability of the attachment of the stop element to the vehicle body or to the body flap remains the same.
