It is an object of the present invention to provide an improved fastening element.

According to the invention, this object is achieved by a fastening element having the features of claim 1.

Further developments of the invention are the subject matter of the dependent claims.

The fastening element according to the invention for connecting a first component to a second component has:

-a pin-like connection element having a first fastening area and a second fastening area,

a sleeve configured for insertion into the receiving opening of the first component,

a compensation element provided with a receptacle for accommodating the first fastening region and configured for insertion and adjustment in the sleeve in the longitudinal direction,

at least one drive interface is provided on the compensating element, by means of which the compensating element can be adjusted in the sleeve in the longitudinal direction.

The fastening element according to the invention constitutes a releasable tolerance compensation element with subsequent axial adjustment and radial tolerance compensation.

By simply inserting and fastening the sleeve in the first component and screwing the connecting element into the first component, the fastening element can establish a (non-rigid and/or rigid) connection between the two components, for example the vehicle body and the mounted component. After mounting, the fastening element can be adjusted by rotating the connecting element in the axial direction and can be detached again by later pulling the connecting element out of the clip. The adjusted position is retained for further tightening.

The first component may be, for example, a load bearing component, in particular a body panel of a vehicle.

The second component may be, for example, a mounted component such as a rear light or side light.

In one embodiment, the second fastening region has a threaded portion for engagement in a receptacle of the second component. The threaded portion can be designed as a self-tapping thread or a metric thread, in particular a self-locking thread, which engages rigidly and/or non-rigidly in the receptacle of the second component and in particular is screwed into the receptacle. In a further embodiment, the second fastening region can be fixed, in particular pressed, glued, injected or clamped in the second component or be formed integrally with the second component.

In one embodiment, the drive interface is designed as a lower drive interface which points away from the connecting element inserted into the compensating element and/or as an upper drive interface which points towards the connecting element inserted into the compensating element. In this way, the compensating element can be adjusted when the sleeve is fastened in the first component and the connecting element is screwed into the second component.

In one embodiment, the drive interface includes a hexagonal or square head or recess, a hexalobular external or internal drive feature, a slot, or a cross-slot. Other shapes of the drive interface are also possible.

In one embodiment, the compensating element and the sleeve have complementary threads to each other. In this way, adjustment in the longitudinal direction can be made by rotation.

In an embodiment, the connecting element is releasably retained in the receptacle, but restrained against removal. In this way, the second component can be removed from the first component and replaced thereon. In this case, the axial distance previously adjusted in the second assembly by rotating the connecting element is preserved.

In one embodiment, the compensating element is designed to be elastic in the region of the receptacle.

In one embodiment, a separation flange is provided on the connecting element to separate the first fastening region from the second fastening region.

In one embodiment, a nut is provided for screwing onto the sleeve in order to hold the fastening element on the first component by means of a screw connection. Alternatively, a clip connection is also possible.

In one embodiment, the nut and sleeve have mutually complementary teeth configured to prevent the nut from loosening or becoming lost.

In one embodiment, a spring element for the rigid or non-rigid connection of the compensation element is arranged in a receptacle on the connecting element. Such a spring element, which is axially fixed in the receptacle in both directions, can transmit forces, such as insertion forces and withdrawal forces, in particular compression forces or tensile forces, axially in both directions and can dissipate them in the direction of the receptacle, so that the fastening element can be used several times.

In one embodiment, the sleeve has an interface to be received in the receiving opening of the first component, wherein the interface has a cross section different from a circular shape, and/or wherein the interface has a cross section smaller than the receiving opening. Thus, a rotation of the sleeve in the receiving opening is prevented and/or a position adjustment transverse to the longitudinal direction is made possible.

Detailed Description

Fig. 1 is a schematic view of a fastening element 1 for connecting a first component 4 to a second component 6 and compensating for tolerances between the first component 4 and the second component 6. Fig. 2 is a schematic view of the fastening element 1 from obliquely below, see the lower drive interface 1.12. Fig. 3 is a schematic cross-sectional view of the fastening element 1. Fig. 4 is a schematic view of a part of the first component 4 with the receiving opening 4.1. Fig. 5 is a schematic view of the fastening element 1 seen from below.

The fastening element 1 may be substantially cylindrical and have a sleeve 1.1.

The fastening element 1 may be constructed in one or more parts and may, for example, be formed from a metal or plastic material or from a combination of metal and plastic parts.

In a further aspect, the sleeve 1.1 has a head 1.3, which can be designed as a sealing element, for example, in the form of a disk or mushroom head, and which has a diameter which is greater than the diameter of the sleeve 1.1. Alternatively, the head 1.3 may also comprise only at least two sections, for example three sections, of the mushroom head. The sleeve 1.1 forms a socket for the fastening element 1. The sleeve 1.1 and the head 1.3 can be formed as one component, in particular made of plastic. For example, the sleeve 1.1 and the head 1.3 are designed as 2-component injection-molded plastic parts. The sleeve 1.1 can be made of a harder plastic and the head 1.3 can be made of a softer plastic.

The compensating element 1.4 can be arranged in the sleeve 1.1 in an adjustable manner, in particular in the axial direction y of the sleeve 1.1. The sleeve 1.1 and the compensating element 1.4 can be provided with mutually complementary threads 1.8, 1.9.

The compensating element 1.4 is provided with a receptacle 1.2, in particular a hollow cylinder.

The spring element 2, which may be made of metal, in particular of steel material, preferably of spring steel, may be arranged in the receptacle 1.2, for example.

The fastening element 1 also has a pin-like connection element 5.

The first component 4 is, for example, a load-bearing component, in particular a body panel of a vehicle. The receiving opening 4.1 can have a cross section deviating from a circular shape. The sleeve 1.1 can have an interface 1.5 complementary to the receiving opening 4.1. The receiving opening 4.1 can also be made larger than the interface 1.5 in order to allow position compensation in transverse directions x and z transverse to the axial direction y of the sleeve 1.1.

In particular, the receiving opening 4.1 and the mouthpiece 1.5 may each have an approximately square cross section, preferably with rounded corners.

The receptacle 1.2 in the compensation element 1.4 is designed to be open at least on one side, in particular on the head side, in order to accommodate the connecting element 5. In particular, the receiving portion 1.2 can also be designed as a through-hole at the bottom end and can therefore be open on both sides.

The second component 6, for example a mounted component, for example a tail light or side light, can be fixed in an axially adjustable manner to the first component 4, for example a carrier component, such as a body panel.

The fastening element 1 can be pre-assembled on the first component 4, for example on a vehicle component. The fastening element 1 can be arranged in the receiving opening 4.1 of the first component 4, for example, by means of a snap-on or clip connection and is held there by a rigid and/or non-rigid connection. In the embodiment shown, a nut 1.6 is provided which can be screwed onto the sleeve 1.1 in order to hold the fastening element 1 on the first component 4 by means of a screw connection. For this purpose, further complementary threads 1.10, 1.11 can be provided in the nut 1.6 and on the sleeve 1.1. Furthermore, the nut 1.6 may have a collar 1.7 for placing on the first component 4.

Likewise, the connecting element 5 can be pre-assembled on the second component 6, for example on a tail light or a side light. For example, the connecting element 5 has a threaded portion 5.1. The threaded portion 5.1 can be designed as a self-tapping or metric thread, in particular as a self-locking thread, which engages rigidly and/or non-rigidly, in particular screws, into a receptacle of the second component 6. Alternatively, the connecting element 5 may be fixed, for example pressed, glued, injected or clamped in the second component 6.

Subsequently, the connecting element 5 with the preassembled second component 6 is fastened to the first component 4, wherein the connection of the two components 4 and 6 is axially adjustable.

The connecting element 5 is designed as a screw with a separating flange 5.6 in order to separate a first fastening region 5.4 for the receptacle 1.2 in the compensating element 1.4 from a second fastening region 5.5 for the second component 6. The separating flange 5.6 projects radially outwards and is designed in the manner of a bolt collar in the form of a disk and can be provided with a hexagonal or square shape.

In one embodiment, the lower drive interface 1.12 is provided on the compensation element 1.4, for example a hexagonal or square head or recess, a hexalobular external or internal drive feature, a notch or a cross-notch. The lower drive interface 1.12 is directed in particular away from the connecting element 5 inserted into the compensating element 1.4 and can project from the sleeve 1.1 when the compensating element 1.4 is arranged in the sleeve 1.1.

In one embodiment, an upper drive interface 1.13, such as a hexagonal or square head or recess, a hexalobular external or internal drive feature, a notch or a cross-notch, is alternatively or additionally provided on the compensation element 1.4. The upper drive interface 1.13 is directed in particular toward the connecting element 5 inserted into the compensating element 1.4 and is accessible in particular when the connecting element 5 is not inserted into the compensating element 1.4.

The nut 1.6 and the compensating element 1.4 can have mutually complementary teeth 1.14, 1.15, which inhibit or prevent the nut 1.6 from loosening or being lost.

The fitting can be formed by fastening the threaded portion 5.1 in a receiving portion of the second component 6, for example by screwing it therein, as shown in fig. 6. For example, the threaded portion 5.1 can be screwed in until the detachment flange 5.6 meets the second component 6.

In one embodiment, as shown in fig. 7, the sleeve 1.1 with the compensating element 1.4 inserted therein is fixed to the connecting element 5, for example with a rigid and/or non-rigid connection. The connection, for example by means of the spring element 2, can be released again by pulling the connecting element 5 out of the receptacle 1.2. For this purpose, the compensating element 1.4 can be designed to be correspondingly elastic.

Alternatively, the sleeve 1.1 with the compensation element 1.4 inserted therein has been fastened to the connecting element 5 before the assembly 4, 6 is fitted, for example, with a rigid and/or non-rigid connection.

The assembly comprising the second component 6 and the fastening element 1 fixed in the receptacle can be brought to the first component 4, for example a body panel of a vehicle, wherein the sleeve 1.1 can be inserted into the receiving opening 4.1 of the first component 4, as shown in fig. 8. Fig. 8 is a schematic view of a fastening element 1 inserted into a first component 4 and a second component 6 connected thereto. In this state, a position compensation can be carried out in the transverse directions x and z transverse to the axial direction y of the sleeve 1.1. The cut-out 4.1 may also have a smaller diameter than the head 1.3.

Fig. 9 is a schematic view of the fastening element 1 inserted into the first component 4 and the second component 6 connected thereto, wherein the nut 1.6 is screwed onto the sleeve 1.1. The fastening element 1 is thus fastened to the first component 4 and fixed with respect to the transverse directions x and z.

After the second component 6 has been mounted on the first component 4 by means of the fastening element 1, the axial position of the second component 6 relative to the first component 4 can be adjusted by rotating the compensating element 1.4 by means of the lower drive interface 1.12. If the second component 6 is then removed in the axial direction y as shown in fig. 10, the bolt-shaped connecting element 5 remains in the receptacle 6.1 of the second component 6 and the sleeve 1.1, the compensating element 1.4 and the nut 1.6 remain in the receptacle opening 4.1 of the first component 4, which is, for example, a load-bearing component such as a vehicle body panel. Fig. 10 is a schematic view of the fastening element 1 after removal of the second component 6 from the first component 4.

In this state, the upper drive interface 1.13 is also accessible, so that the compensating element 1.4 can also be adjusted in the axial direction y in this way.

In an alternative embodiment, the receptacle 1.2 and the connecting element 5 in the first fastening region 5.4 may comprise a circumferential groove of the connecting element 5 and a complementary projection of the receptacle 1.2.

In an alternative embodiment, the receptacle 1.2 and the connecting element 5 may comprise a radial projection of the connecting element 5 in the first fastening region 5.4 and a complementary circumferential groove in the receptacle 1.2.

In an alternative embodiment, the receptacle 1.2 and the connecting element 5 may comprise in the first fastening region 5.4 a radial projection of the connecting element 5 and a complementary circumferential groove in the receptacle 1.2, wherein the projection may extend in the direction of the second component 6 at a narrower angle relative to the connecting element 5 than in the opposite direction, so that the connecting element 5 is inserted into the receptacle more easily than it is pulled out of the receptacle 1.2.

In an alternative embodiment, the connecting element 5 can have a circumferential groove in the first fastening region 5.4, and the receptacle 1.2 can have complementary spring arms on its inside, which engage in the groove. The resilient arms may be fastened to the receiving portion 1.2 at their ends facing the head portion 1.3 and may project in opposite directions. The recess in the connecting element 5 can extend at a steeper angle relative to the connecting element 5 than in the opposite direction in the direction away from the second component 6, so that the connecting element 5 is easier to insert into the receptacle 1.2 than to pull it out of the receptacle.

In an alternative embodiment, the connecting element 5 may have a circumferential groove in the first fastening region 5.4, and the receptacle 1.2 may have a complementary projection on its interior which engages with the groove. The recess in the connecting element 5 can extend at a steeper angle relative to the connecting element 5 than in the opposite direction in the direction away from the second component 6, so that the connecting element 5 is easier to insert into the receptacle 1.2 than to pull it out of the receptacle.

In an alternative embodiment, the connecting element 5 can be formed cylindrically in the first fastening region 5.4 and the receiving part 1.2 can also be formed complementarily cylindrically in its interior.

In an alternative embodiment, the connecting element 5 can be formed substantially cylindrically in the first fastening region 5.4 and provided with corrugations, and the receptacle 1.2 can likewise be formed substantially cylindrically on its inner side. The spring element 2 is arranged in the receptacle 1.2 and is axially firmly connected to the inside of the receptacle 1.2 in both directions.

Such a spring element 2, which is axially fixed in the receptacle 1.2 in both directions, can transmit forces, such as insertion and withdrawal forces, in particular compression or tensile forces, axially in both directions and can dissipate them in the direction of the receptacle 1.2, so that the fastening element 1 can be used several times.

In one possible embodiment, the sleeve 1.1 is made of plastic and the spring element 2 is made of metal.

The spring element 2 comprises, for example, a base body from which spring arms project radially outward, which spring arms engage rigidly and/or non-rigidly in the interior of the receptacle 1.2. The axial force and its dissipation in both directions can be set in a targeted manner by the spring arms.

The base body of the spring element 2 is, for example, sleeve-shaped. The plurality of spring arms are arranged or formed in rows with respect to one another, for example along the longitudinal extension of the base body. The spring arms may be arranged or formed diametrically opposite each other with respect to the base body. This arrangement of the spring arms on the base body, in particular in two rows or rows, enables symmetrical force transmission and dissipation.

Alternatively, a single row or row arrangement of spring arms may be formed on the base body, which allows for asymmetric force transmission and dissipation.

In addition, the base body can have wave-shaped sections in certain regions outside the rows of spring arms. This wavy section of the base body allows a frictional or clamping connection to be made with the interior of the receptacle 1.2 at the outside of the rigid and/or non-rigid connection of the spring arms with the interior.

The spring arms can project radially outward and then, when inserted into the receptacle 1.2, penetrate into the interior of the receptacle 1.2 and form a rigid and/or non-rigid connection with the interior of the receptacle 1.2.

Furthermore, the base body can have radially inwardly directed spring arms which project radially inwardly from the base body.

For example, adjacent spring arms and at least one row have spring ends that alternate radially outward and radially inward.

Further, the spring arms of one or each row may be arranged at an axial distance from each other. This achieves an axial adjustability of the connection, for example by means of a corresponding distance in the adjustment step. This enables the axial adjustment step to compensate tolerances, in particular small assembly tolerances, in small steps of, for example, 0.2cm to 1cm, in particular 0.35 cm.

The spring arm may be designed as a latching arm, a ratchet or clamping arm, or as another suitable shape which enables a rigid and/or non-rigid connection with an adjoining surface, for example the interior of the receiving portion 1.2.

In all embodiments, the receptacle 1.2 can be formed in the region of the head 1.3 in a funnel-like manner to facilitate the insertion of the connecting element 5.
