Description

Stop arrangement for a position-adjustable element on a vehicle body

The present invention relates to a stop arrangement for a

position-variable element on a vehicle body, a Anschlagementement for such a stop assembly and a motor vehicle with such a stop assembly.

A motor vehicle usually has a body on which a movable body member, such as a tailgate, is mounted. The tailgate is usually hinged to the body via two hinges. Furthermore, the tailgate is locked in its closed state in a locking device and terminates flush with adjacent body elements. In the closed state of the tailgate, the tailgate is usually on at least two stop buffers. One

Bump stop can be attached to the tailgate or on the body itself and is often designed such that it is adjustable in height, so that a closing comfort of the tailgate can be adjusted and buffer the tailgate in the closed state in abutment against the stop and in the

latched state is biased. In most cases, such a stop buffer is formed elastically deformable within certain limits. In this case, the stop buffer is elastically deformed in the closed state of the tailgate and acts on the tailgate with a bias.

Such a bump stop can be attached to the tailgate or the body in various ways. For example, DE 10 2006 017 141 A1 shows a stop buffer which consists of a cylindrical body and on whose outer periphery an external thread is formed, which is screwed into a matching hole in the vehicle body or in the flap.

A further fastening possibility of such a buffer or stop is shown in DE 10 2007 051 103 A1. In particular, there is shown a höhenversteilbarer buffer 2, which has a foot which can be pressed into a bore of a tailgate or body and in the manner of a snap connection to the bore can be fixed.

Also in DE 10 2009 022 809 A1 an adjustable stop buffer is shown, which can be fastened via elastically deformable latching elements in an opening of a vehicle body or a position-variable element.

In addition, bumpers are known in the manner of a

Bayonet closure, i. a plug-in rotary connection, are attachable to an opening in a tailgate or a vehicle body.

It is now the object of the present invention, a stop assembly for a position-variable element on a vehicle body with a

Vehicle body is improved. Furthermore, it is an object of the invention to provide 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 assembly having the features of claim 1. Furthermore, this object is achieved by a stop element according to claim 12 and a motor vehicle according to claim 13. Further developments of the invention are described in the dependent claims.

In particular, a Anschiaganordnung according to the present invention for a position-variable element on a vehicle body, a stop element, which has a plug-and-turn connection with the position-variable element or with the vehicle body is connectable. The plug-in rotary connection also has middle! on, which cause a radial clamping of the stop element.

The position-variable element may be a body flap. A

Body flap is preferably a tailgate or a front door. The vehicle body may preferably be a motor vehicle body. A plug-in rotary connection is in particular a connection in which a connection is made via a plug-in operation and an adjoining turning process. An example of such a plug-and-turn connection is a so-called bayonet lock. Radial clamping refers to a clamping direction that is perpendicular to a longitudinal axis of the stop element. An axial direction of the stopper member is basically a

Direction in which a stop acts, that is, a direction substantially perpendicular to the position-variable element and / or the vehicle body. Radial clamping according to the present invention may also mean that clamping takes place in the direction of a plane of the position-variable element or the vehicle body.

According to one embodiment of the present invention, said means are designed such that the radial clamping acts radially centering on the stop element.

Radially centering according to the present invention means that by the plug-and-turn operation, in particular the rotation process, a centering in the radial direction positioning of the stop element takes place.

According to one embodiment of the present invention, said means are formed by a plug-rotation connection projection of the stop element and a receiving opening of the position-variable element or a receiving opening of the vehicle body for receiving the plug-rotation connection projection. In other words, the receiving opening is in the

position-variable part or the vehicle body formed and the

Plug-in rotary connection projection can be inserted or received in the receiving opening. In particular, the means are designed such that the Plug-turn connection projection is first inserted into the receiving opening and then rotatable in a certain Winkeibereich until the radial clamping of the stop element acts.

In other words, at the clamping portion of the outer circumference and the associated clamping portion of the inner circumference, a radial excess increases progressively with increasing rotation, whereby a progressively higher fastening force or clamping force can act. This is a radial

Attachment or clamping particularly easy to produce.

Preferably, in the Anschiaganordnung the clamping portion of the outer periphery of the plug-rotary connection projection - both eccentric and non-eccentric design of the clamping portion of the outer Circumference and / or the associated clamping portion of the inner circumference - have ribs which are arranged such that form ribs and valleys, areas between the ribs, in the radial direction, that is transverse to the rotational direction of the plug-rotation connection projection in the radial direction, wherein the ribs are in particular elastically and / or plastically deformable.

Ribs have the advantage that they are easier to deform elastically or plastically compared to a continuous surface. This is a better one

Clamping possible. Furthermore, a larger angle of rotation of

Plug-in rotary connection projection until reaching the desired

Clamping force possible.

In the attachment arrangement with the clamping section of the outer circumference and the associated clamping section of the inner circumference, it is preferred

Plug-in rotary connection projection with several clamping sections, z. B. two, three or four clamping portions, formed, wherein the plurality of clamping portions are arranged in particular symmetrically on the circumference of the plug-rotation connection projection and the receiving opening has the same number of associated clamping portions of the inner circumference.

Accordingly, the attachment element can be held in the axial direction by the flange and the opposite surface of the plug-in rotary connection projection, between which the edge of the receiving opening is arranged. The flange and the opposite surface may be formed so that the edge of the receiving opening between the flange and the

opposite surface is clamped, especially when the

Plug-in rotary connection projection is rotated.

The opposite surface may be formed continuously or may have interruptions.

Preferably, the edge of the receiving opening has a recess for passage of the flange.

According to one embodiment of the stop arrangement according to the present invention, the plug-in rotary connection projection can be formed from 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 position-variable element or the vehicle body, and a clamping action can be achieved even with a small torque.

Preferably, in the stopper assembly according to the present invention, the stopper member has an adjustable stopper member.

Below is a brief description of the figures:

Figure 1 shows a schematic side view of a stop assembly according to the first embodiment of the invention.

Figure 2 is a schematic sectional view of the stopper assembly according to the first embodiment of the present invention taken along a sectional plane A-A shown in Figure 1 with the stopper member in a fully clamped condition.

Figure 3 shows a schematic sectional view according to the first

Embodiment of the present invention along a sectional plane AA shown in Figure 1, wherein the stopper member is shown in an inserted but not rotated or clamped state. The following is a description of the embodiments according to the present invention with reference to the figures.

A first embodiment is explained with reference to Figures 1 to 3.

In Figure 1, a stopper assembly 1 is shown in which a tailgate 3, d. H. a position-adjustable element according to the present invention, in a stop position 11 relative to a vehicle body 5 is located. The stop layer 11 is defined by a stop element 7, which has a

Plug-and-turn connection 9 is connected to the vehicle body 5.

The plug-in rotary connection 9 is in particular by a

Plug-rotation connection projection 13 of the stopper element 7 and a

Receiving opening 15 of the vehicle body 5 is formed. The plug-rotation connection projection 13 has a flange 23 having an edge of

Receiving opening 15 engages behind. The plug-in rotary connection projection 13 is held in the axial direction by a form fit through the flange 23 and the flange 23 opposite surface 21.

In Figure 2 is a section through the stop assembly 1 along the

Body level A-A shown in Figure 1. In particular, it is shown in Figure 2, as the plug-rotation connection projection 13 is clamped radially in the receiving hole 15. As a result, the plug-in rotary connection projection 13 is held positively in the radial direction. Furthermore, the plug-in rotational connection projection 13 is held by the radial clamping at least frictionally in the axial direction.

The receiving hole 15 has four clamping portions 19 on the inner circumference of the receiving opening 15. Opposite clamping portions 19 are each formed identically, with adjacent clamping portions 19 differ from each other. But it can also be formed the same way all four clamping sections. It would also be possible for. B. form only three identical clamping sections. The clamping portions 19 are formed eccentrically with respect to the center axis or longitudinal axis of the receiving opening 15 and the plug-pivot connection projection 13.

Furthermore, the plug-in rotary connection projection 13 has four clamping sections 17, which are designed to correspond to the clamping sections 19. The clamping portions 19 and 17 are formed symmetrically to the longitudinal axis of the plug-pivot connection projection 13 and the receiving opening 15.

The clamping portions 17 on the periphery of the plug-pivot connection projection 13 are formed in the form of transverse to the cutting plane ribs 171, between which Täier 172 extend. In particular, everyone points

Clamping portion 17 three ribs 171 on. A connecting line or surface of the front ends of the ribs 171 is in an eccentric shape, i. H. eccentric with respect to the longitudinal axis of the plug-pivot connection projection 13, formed. In other words, each KSemmabschnitt 17 has an eccentric surface through which valleys are substantially parallel to the longitudinal axis. The ribs 171 are characterized by their geometry when rotating the

Plug-rotation connection projection 13 elastically deformable and allow a particularly good clamping action.

In FIG. 2, the stop element 7 or the plug-in rotary connecting projection 13 is shown in a state in which it is inserted into the receiving opening 15 and twisted through the greatest possible angle relative to the receiving opening 15, so that a desired clamping force is achieved is reached. In other words, the state in which the stop element 7 is completely fixed to the vehicle body 5 or clamped thereto is shown in FIG. In particular, a self-centering Radialktemmung is shown, wherein the radially acting

Centering is formed in particular by the symmetrically arranged Kiemmabschnitte 17 and 19 and their eccentric action. The eccentric

Clamping portions 17 and 19 are each twisted to a press fit and clamped together. In this case, there is an elastic and / or plastic deformation of the ribs 171, in particular in the direction of rotation. By means of the described stop arrangement, the stop element 7 can be mounted from one side on the vehicle body 5 or alternatively on the tailgate 3. In particular, the stop element 7 can be positioned particularly accurately with respect to the radial position, since, as described, the

Clamping connection radially centering acts. Further, since the connection is formed as a Radialkiemmung, it is not possible to move the Anschiagelement 7 in a radial direction. In addition, the Radialkiemmung also acts at least non-positively in the axial direction. As a result, requirements for tolerances for the axial positive locking by the flange 23 and the opposite surface 21 can be reduced.

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

In addition to the Radialkiemmung described above, the

Plug-in rotary 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-pivot connection projection 13 serves to rest on the vehicle body 5, in particular the edge of the

The flange 23 engages behind the edge of the receiving opening 15. The edge of the receiving opening 15 further has four recesses 25, the passage of the flange 23 and the clamping portions 17 at a plug-in rotation of the connecting projection 13 into the receiving opening 15th enable. In the step of rotating the plug-pivot connection projection 13, the flange 23 can then engage behind the edge of the receiving opening 15, so that the effect is achieved similar to a bayonet closure. Furthermore, the plug-in rotary connection projection 13 has two stopper parts 27 each received in one of two opposing recesses 25 and defining a rotation angle of the plug-and-turn connection projection 13.

Since the stopper assembly according to the first embodiment of

present invention not only has a Axialklemmung, but also a very effective radial clamping of the plug-rotary connection projection 13 at the Receiving opening 15, a requirement on the accuracy of a height of the receiving opening 15 is considerably reduced, as already explained above.

Thus, the plug-in rotary connection projection can also be easily mounted on a stamped in a body panel receiving opening whose dimensional accuracy is lower.

In FIG. 3, by the way, a state is shown in which the

Plug-rotation connection projection 13 is inserted into the receiving opening 15, but not yet twisted.

Below is a stopper assembly according to a second

Embodiment of the present invention described, wherein a

Description of features associated with the first embodiment

match, is omitted. The second embodiment is not shown in the figures.

In contrast to the first embodiment are in the second

Embodiment Clamping surfaces of a receiving opening is not eccentric. Only clamping surfaces of the plug-pivot connection projection are formed eccentrically. Similar to the first embodiment, the clamping surfaces of the plug-pivot connection projection are formed by ribs which extend in the longitudinal direction of the plug-pivot 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.

Equally to the first Ausführungsbeispiei acts

Plug-and-turn connection of the second embodiment radially centering and the plug-rotation connection projection is in complete assembly of the

Stop element radially non-displaceable.

The first and second embodiments described above are each provided with four pairs of clamping surfaces - a pairing is achieved by a clamping surface of the receiving opening and an associated clamping surface of the plug-in connection. Rotary connection projection formed - formed. In a modification of these embodiments may alternatively be three or five

Be provided clamping surface pairings. Likewise, an alternative with two clamping surface pairings is conceivable.

Further, the clamping surfaces of the plug-pivot connection projection are formed with ribs. Alternatively, however, these clamping surfaces may also be formed similarly to the clamping surfaces shown on the receiving opening without ribs.

Furthermore, it is conceivable that the clamping surfaces of

Plug-rotation connection projection are not formed eccentric, whereas the clamping surfaces of the receiving opening are formed eccentric.

Ultimately, any training of clamping surfaces is possible, provided that a clamping surface pairing a radial clamping in a rotation of the

Plug-in rotary connection projection allows.

The plug-in rotary connection projection of the present embodiments is formed of plastic, whereas the vehicle body, or the part of the vehicle body, on which the stopper member is fixed, is formed of a metal sheet. Of course, the plug-in rotary connection projection also consist of a metallic material and also the vehicle body may consist of a plastic or a fiber-reinforced plastic.

To the same stop element with the same

Plug-in rotary connection projection to be able to mount different interfaces in the vehicle body or in a body flap, a height of the receiving hole should be approximately equal. In order to be able to realize this with different sheet thicknesses, it is conceivable to emboss a sheet metal in the region of the receiving opening to the desired standard height. Since such an embossing can take place only within a certain range of accuracy, ie a height of the receiving hole is then subject to fluctuations in a certain tolerance range, the present invention is particularly advantageous because they not only Axialklemmung but in particular a fixed Radialklemmung the Anschiagelements or plug-rotary connection projection allows. As a result, the requirements for Axiaiklemmung are significantly lower while maintaining the durability of attachment of the stop member to the vehicle body or on the body flap.
