Description

retaining element

The invention relates to a holding element, in particular for the relative positioning of a component on a support structure or for holding an attachment to the component, as described in claims 1 and 11.

DE 20 2009 013 312 U1 describes a connecting device consisting of a sheet metal component and an associated threaded insert. The sheet metal component has a bore into which the threaded insert is inserted. The threaded insert is formed by a cup-shaped component having a radially projecting connecting flange in the region of its open end. This is in the assembled state at the sheet metal component side facing. The thread is designed as an internal thread in the threaded insert. The connection between the connecting flange and the facing surface of the sheet metal component takes place by means of a resistance hump welding method. Through this welding process, a cohesive connection of the connecting flange with the sheet metal component takes place.

DE 10 2006 038 624 A1 has disclosed a method for fixing a component on a joining partner to be painted. The component to be fixed is fixed to the joining partner with a section of a not completely crosslinked, heat-activatable adhesive film. In this fixed position of the joining partner is painted together with the component held on it and then dried the painted joint partner together with the fixed thereto component in a thermal drying. The resulting thermal energy leads to a complete cross-linking of the heat-activatable adhesive film, so that the component is permanently fixed on the joining partner.

Another embodiment of a holding element is designed such that it has a disk-shaped, provided with openings base part to which a threaded pin, a nut or the like is welded. On the side facing away from the welding element a planar connecting surface is formed, with which the holding element thus formed can be attached to a component. This is done by a gluing process, wherein the adhesive can also penetrate into the openings arranged in the base part, so as to allow an additional increase in the torsional forces to be transmitted.

The present invention has for its object to provide a holding element for transmitting forces to a component made of a particular reinforced with carbon fibers plastic, in which a force introduction positionally accurate and without damage to the component is possible.

This object of the invention is solved by the features of claim 1. The resulting from the features of claim 1 advantage is that so by a

Deep-drawn part is an integrally formed holding member for power transmission can be created in which the base part is formed a connection surface for connection to the component and still formed in its center a connecting part with a rectangular part to the base orientation. Due to the design of the connecting part as a tubular hollow body can be coupled or connected with this most different connection means. Due to the non-cutting shaping in the course of the forming process, it is possible in a mostly multi-stage forming or manufacturing process without extensive additional work to create a holding element, which is so inexpensive to produce and still the possibility for the transmission of sufficiently high forces th can be created.

Also advantageous is a further embodiment according to claim 2, since the extent of the clamping effect with respect to the wall thickness of the component to be clamped can be determined exactly by the predetermined axial distance between the support surface formed on the collar and the connecting surface on the base part. With this predetermined axial distance can be ensured in all cases that is not damaged in a system of an attachment or a support structure to be connected to an adjacent in the region of the support surface of the collar surface portion of the component. With an excessively strong clamping of the component, this can lead to damage up to a crimping of the same, which can lead to a subsequent breakage of the component. Due to the larger surface area of the support surface relative to the cross-sectional area of the connecting part, the surface pressure can thus be reduced when the support surface abuts. A further advantage is an embodiment according to claim 3, since this provides a connection possibility in which the connecting part is arranged protruding on the surface of the component facing away from the connecting surface. Thus, the holding element can be supported with its base part on the side facing away from the connecting part on the component, in which case directly attached to the connecting part of the attached thereto attachment or the support structure can be easily attached.

As a result of the embodiment according to claim 4, it is possible to arrange the holding element with its supporting surface formed on the collar in a roughly planar manner relative to the surface of the component. As a result, disturbing projections, for example in the area of the visible side, are avoided and a simple fastening possibility on the retaining element can be created. According to another embodiment according to claim 5, a uniform clamping effect distributed over the surface of the component is made possible when attaching an attachment or when attaching the component to a supporting structure.

Also advantageous is a development according to claim 6, since it is possible to fall back on standard connection means which are available on the market in a variety of different embodiments in a simple and cost-effective manner.

In the embodiment according to claim 7 it is advantageous that an additional hardening of the connecting part in the course of thread forming can be achieved. This means that even with smaller cross-sectional dimensions of the connecting part or even with smaller thread dimensions, it can be found that only reshaping takes place and thus the danger of breakage due to notch effects is reduced.

Through the development according to claim 8 ensures that the connection can be made with a simple mother, which is available as a standardized component.

Due to the design according to claim 9 can also be easily and inexpensively connected to the holding element can be created with standard components. Also advantageous is an embodiment according to claim 10, since in the bonding of the retaining element with the component, the adhesive can penetrate into the openings. As a result, a better rotation with respect to the transmission of torques is created, the formed and cured adhesive forms a peg-shaped approach, which can absorb this to some extent with torsional forces occurring.

However, the object of the invention can be solved independently by the features of claim 11. The resulting from the combination of features of this claim advantages are that such a holding element can be created, in which no additional openings or openings are provided for the attachment of attachments or in the attachment of the component to a support structure in the component and still one Secure adhesive bond between the retaining element and the component can be achieved. By providing the spacer elements, a predefined distance is thus created between the connecting surface and the surface of the component, which is necessary, depending on the adhesive used, to achieve a secure and permanent adhesion of the retaining element to the component. Furthermore, this also creates a holding element in a single operation, which can be produced in the sense of reworking or additional processing steps without any additional additional work.

In this case, an embodiment according to claim 12 proves advantageous because it can be created between the surface of the component and the connecting surface of the support member and the peripheral circumferential collar a receiving chamber in which the provided for load or power transmission adhesive can be added. The contact surface of the federal government can be provided with a short-term curing or solidifying adhesive in order to achieve in a first step a short positioning and holding of the holding element on the surface of the component. Subsequently, the curing of that adhesive can be carried out, which is located between the connection surface and the surface of the component. This then serves for the permanent

Force application. However, the invention also relates to an assembly with a component, in particular of a carbon fiber reinforced plastic, to which at least one holding element for the introduction of force to the component is attached thereto, as described in claim 13. It is advantageous that such a structural unit can be created in which attachments can be held on the component via the interposition of the holding element or the component itself can be attached to a support structure. By the holding element as a defined power transmission to the component allows, without this being damaged. Of advantage, however, is also an embodiment according to claim 14, as can be done relative to the component relative to a simple positioning of the retaining element. In addition, however, this also creates the possibility to introduce an adhesive between the lateral surface of the transition part and the surface of the opening so as to achieve an additional connection between the holding member and the component here. In addition, a galvanic separation between the holding element and the component can be achieved. This is particularly advantageous in this area, since the attachment of the opening in the component, the carbon fibers arranged in the plastic are severed and so when not providing the adhesive layer contacting between the holding member and the carbon fibers is very easily possible.

In accordance with claim 15, the secure mounting and connection of the retaining element is achieved on the component. In addition, however, a galvanic separation between the holding member and the component is achieved. Finally, however, an embodiment as described in claim 16, possible because the holding or clamping action between the attachment or the support structure and the wall of the component can be fixed. Thus, excessive deformation can be avoided because this can be matched to the corresponding wall thickness of the component by the choice of the axial distance. In this case, the layer thickness of the adhesive layer between the connecting surface of the base part and the surface of the component is also to be considered.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures. Each shows in a highly schematically simplified representation:

Fig. 5 shows a further possible embodiment of a holding element on a component, cut in view.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in position.

In FIGS. 1 and 2, a first embodiment of a holding element 1 is shown in simplified form, which can serve, for example, for the relative positioning of a component 2, which is shown only partially, on a supporting construction not specified. But it would also be possible by means of the support member 1 on the component 2 to attach one or more unspecified or illustrated attachments thereto. Thus, the retaining element 1 serves to be able to transmit forces such as tensile forces, compressive forces as well as moments by means of this to the component 2. This could also be referred to as a force introduction element, the retaining element. In this exemplary embodiment shown here, the base part 3 has an approximately circular disk shape in the region of its outer circumference, wherein the connecting part 4 is formed in the center thereof and, in the center thereof, the connecting part 4 is arranged. Furthermore, the base part 3 has a connection surface 5 facing the component 2, with which it is arranged adjacent to the upper side of the component 2 in the present exemplary embodiment.

The connecting part 4 can in turn be designed differently and serves to accommodate or coupling with a connection means which will be described later. The connecting part 4 defines a longitudinal axis 6 and is further projecting from the base part 3 connected thereto. Thus, the longitudinal axis 6 of the connecting part 4 is preferably oriented with respect to the connecting surface 5 of the base part 3 at an angle of 90 ° thereto. Furthermore, the connecting part 4 is designed here as a tubular hollow body and has at a first end 7 a radially with respect to the longitudinal axis 6 aligned collar 8, which is arranged thereon. Subsequent to the collar 8 there is provided a transition part 9 which extends in the axial direction with respect to the longitudinal axis 6 and which is arranged or formed by the collar 8 in an approximately parallel orientation with respect to the longitudinal axis 6. Preferably, the transition part 9 will have a predominantly cylindrical tubular configuration. The transition part 9 is in turn connected to the side facing away from the collar 8 side with the base part 3.

The connecting part 4, the collar 8, the transition part 9 and the base part 3 are here formed by a non-cutting shaping of a planar sheet metal in the initial state and formed in one piece. This can be done for example in a deep-drawing process or forming in a known manner in several deep drawing stages. The remaining undeformed portion of the base part 3 following the transition part 9 is formed as a planar part formed on the component part 2.

The collar 8 projecting radially from the connecting part 4 has, on its side facing away from the base part 3, a face oriented in a vertical direction with respect to the longitudinal axis 6 Support surface 10 on. Both the connecting surface 5 and the support surface are preferred

10 aligned parallel to each other.

Due to the parallel arrangement of the base part 3 and the collar 8 to each other and between them in the axial direction extending transition part 9 is an axial distance

11 defined between the connecting surface 5 and the support surface 10. Preferably, the axial distance 11 is dimensioned such that it corresponds approximately to a wall thickness 12 of the component 2 in the attachment region of the retaining element 1 on the component 2. In this case, it is understood that the axial spacing 11 can be dimensioned in such a way that it can be designed to be slightly smaller than the wall thickness 12, the wall thickness 12 correspondingly, or even slightly larger than the wall thickness 12. Depending on the choice of the axial distance 11 can thus be achieved starting from a slight clamping of the component 2 to a nearly pressureless mounting of the component 2 on a supporting structure or an attachment to the component 2.

In the present embodiment, the connecting part 4 is provided with a thread, which may also be preferably formed without cutting shaped. The thread provided here is designed as an internal thread. The adjoining the collar 8 transition part 9 toward the base part 3 thereby projects beyond the first end 7 of the connecting part 4 toward a second end 13 of the connecting part 4th

Furthermore, in FIG. 1, a partial section of an unspecified support structure or an attachment is shown in dotted lines. The holding element 1 serves for

Power transmission from the connecting means towards the component 2. For this purpose, an opening 14 passing through this is provided in the component 2 for each of the holding elements 1 provided on the component 2. This opening 14 serves to receive the holding element 1 with its opening 14 facing the transition part 9. In this case, a lateral surface 15 of the transition part 9 of the opening 14 is facing. This opening 14 can further serve for the relative positioning of the holding element 1 with respect to the component 2. Thus, the opening 14 may have a clear width, which is slightly larger than an outer dimension of the transition part 9 in the region of its lateral surface 15. The opening 14 may bei- For example, be designed as a circular bore, so as to make their production easy. Regardless, it would also be possible to choose any other cross-sectional shape and the outer circumferential surface 15 of the transition part 9 also adapted to this cross-sectional shape. It would thus be possible, for example, to select a polygonal cross-sectional shape, in order thereby to achieve a certain securing against rotation of the retaining element 1 relative to the component 2.

The component 2 can be formed for example of a carbon fiber reinforced plastic. For further connection or mounting of the retaining element 1 on the component 2, an unspecified adhesive layer can be arranged at least between the component 2 and the connecting surface 5 of the base part 3 and the lateral surface 15 of the transition part 9. This adhesive layer serves for the fixed holding or fixing of the retaining element 1 on the component 2, so that a force can be introduced here. In addition, however, the adhesive layer can also be used to insulate the retaining element 1 from the component 2, in order, for example, to achieve this. to avoid the formation of a galvanic element between the carbon fibers and the holding element 1. The retaining element 1 is, as described above, preferably formed from a metal part, which is usually to be separated galvanically from the component 2. If this galvanic separation is dispensed with, the risk of corrosion may exist, and this is also dependent on the selected material of the retaining element 1.

In order not only to achieve adhesion as well as a torsion-proof mounting of the holding element 1 with its base part 3 on the component 2, a plurality of openings 16 passing through the base part 3 may be arranged in the base part 3 in this. The openings 16 are best seen in FIG. 2.

If an adhesive layer is applied to the connecting surface 5 and / or the surface of the component 2 facing it for the purpose of connecting the holding element 1, the openings 16 serve to displace a certain proportion of the adhesive into the openings 16 and cure them accordingly. By means of this at least partial filling of the apertures 16, an additional securing against rotation of the holding element 1, in particular its base part 3, on the surface of the component 2 can be achieved. Furthermore, it is still shown in dashed lines that on the side facing away from the collar 8 side of unspecified support structure, the previously briefly described fastener 17 may be arranged. When a thread is selected in the connecting part 4, it may be, for example, a screw in the most widely known embodiments. Furthermore, a securing element and / or a disk can also be provided in a known manner between the head of the fastening element 17 and the supporting structure or an attachment in a known manner.

It is essential in this embodiment shown here that the radially projecting collar 8 is arranged on the connecting part 4, which carries the support surface 10, with which the holding element 1 rests against the support structure and / or the attachment or attachment. By this radial collar 8, the surface area of the support surface 10 is increased relative to the cross-sectional area of the tubular connecting part 4, so that here the surface pressure can be reduced.

In addition, a certain degree of self-centering of the retaining element 1 relative to the component 2 is achieved by the interaction of the lateral surface 15 with the surface bounding the opening 14. Thus, no special positioning operations are necessary for the assembly of the support member 1 on the component 2 and it can be done easily with a certain application of adhesive and the subsequent positioning of the support member 1 with its transition part 9 in the opening 14, the arrangement on the component 2.

FIG. 3 shows a further embodiment of the holding element 1, which may be independent of itself, wherein the same reference numerals or designations are used again for the same parts as in the preceding FIGS. 1 and 2. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 and 2 or reference. This holding element 1 is in turn formed in one piece from a planar sheet metal. This holding element 1 shown here differs from the holding element 1 shown in FIGS. 1 and 2 only in that the connecting part 4 is oriented opposite thereto than the connecting part 4 shown in FIGS. 1 and 2. This holding element 1 in turn comprises a base part 3, extending in the axial direction transition part. 9 towards the radially aligned collar 8, which is connected in the region of the first end 7 with the connecting part 4 and passes into this. In the component 2, in turn, at least one opening 14 is provided for the holding element 1, which is designed to receive the holding element 1, in particular its transition part 9. The lateral surface 15 serves as a centering element in the opening 14 of the component. 2

On the radially projecting collar 8, in turn, the support surface 10 is formed on the side facing away from the connecting surface 5 side. Between the connecting surface 5 and the support surface 10 extends the axial distance 11, which in turn corresponds approximately to the wall thickness 12 of the component 2. For holding and better fixation of the base part 3 at the

Surface of the component 2 can in turn be provided in the base part 3 of this penetrating openings 16. These serve to receive the adhesive layer formed by the adhesive, with which the retaining element 1 is attached to the component 2. The adhesive layer in turn serves for the galvanic separation between the holding element 1 and the component 2.

The connecting part 4 is also designed here as a tubular hollow body and closed in the region of its second end 13 with an end wall 18. This end wall 18 may be provided, but it is independently possible but not to form or omit them.

The adjoining the collar 8 transition part 9 projects beyond the first end 7 of the connecting part 4 on the side facing away from the second end 13 side. Thus, the connecting part 4 projects beyond the support surface 10 on the side facing away from the base part 3 side. Furthermore, it is shown here that the connecting part 4 is provided with an external thread, which in turn is preferably formed without cutting shaped.

Thus, for example, a nut or the like can be used as a connecting element with the external thread of the connecting part 4 in order to be able to support an attachment on the component 2, for example, and / or to fasten the component 2 to a supporting structure. The surface area of the above-described support surface 10 on the collar 8 is dependent on the one hand on the dimension of the connecting part 4 and on the other hand on the outer dimension of the transition part 9 limiting lateral surface 15. In the embodiment according to FIGS. 1 and 2, this is the inner dimension, wherein in FIG. 3 this is the outer dimension. If a thread is selected for the connection on the connection part 4, the nominal diameter of the thread in millimeters [mm] is used for the calculation. This can be eg a metric thread with the size M6, M8, MIO, M12, M14, or M16. The surface area of the support surface 10 is assumed to be a circular ring surface, whose outer diameter is the outer dimension of the lateral surface 15 of the transition part 9. The inner diameter for the surface calculation is the nominal diameter of the thread in millimeters [mm]. A ratio of the surface area of the support surface 10 divided by the nominal diameter of the thread can be in a range between 25, in particular 28 and 38, in particular 35. But it would also be possible to form a ratio of the surface area of the circular area with the outer diameter of the lateral surface 15 of the transition part 9 (Agr) to the surface area of the circular area with the nominal diameter of the thread on the connecting part 9 (A ^ i). Here, numbers can range from 3.5 to 7.2.

However, another ratio can also be calculated from the surface area of the support surface 10 divided by the surface area of the nominal size of the thread. The surface area of the support surface 10 is again assumed to be a circular ring surface, the outer diameter of which is the outer dimension of the lateral surface 15 of the transitional part 9. The nominal diameter of the thread is taken as the inner diameter for the surface calculation. This results in ratios in a range between 2.4 and 6.2 depending on the selected nominal diameter of the thread. The smaller the dimension of the thread, the larger is the ratio in the embodiments described above. For the calculations described above, the metric measurement system should be used and the diameters or radii should be used to calculate the areas in millimeters. The dimensions are determined in a plane oriented perpendicular to the longitudinal axis 6 level. These abovementioned ratios ensure that a balance is achieved between the nominal size of the thread and the surface area of the support surface. This achieves a size extent of the support surface in which the surface pressure on the attachment or support structure attached thereto or on the support structure does not exceed a certain extent and thus can not lead to damage even with a longer installation duration.

FIG. 4 shows a further embodiment of the holding element 1, which may be independent of itself, wherein the same reference numerals or component designations are used again for the same parts as in the preceding FIGS. 1 to 3. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 3 or reference. The holding element 1 shown here differs from the embodiments described above in that it is held without the arrangement of the opening 14 in the component 2 at this via an adhesive layer.

The holding element 1 here comprises only the base part 3 and the associated connection part 4, which is designed as a tubular hollow body. This connecting part 4 has an internal thread mounted therein, which is preferably also formed without cutting.

The connecting part 4 is connected at its first end 7 to the base part 3, wherein the connecting part 4 in turn defines the longitudinal axis 6. The longitudinal axis 6 is in turn aligned at a right angle with respect to the connecting surface 5 of the base part 3. In the region of the connecting surface 5 of the base part 3, at least one, but preferably a plurality, of spacer element 19 projecting over the connecting surface 5 is arranged. Also this or these spacer elements 19 are integrally arranged or formed on the holding element 1. Again, in turn, the connecting part 4, the base part 3 and the at least one spacer element 19 are formed by a non-cutting shaping of a planar in the initial state sheet metal and integrally formed. The spacer element 19 serves to define a predefined distance 20 between a majority of the connecting surface 5 and the surface of the component 2.

In the case of a pure holder without prior positioning, at least three spacer elements 19, which protrude beyond the connecting surface 5, are sufficient in order to achieve an unambiguously statically determined distancing of the retaining element 1 relative to the surface of the component 2. The distance 20 serves to form a defined gap width for receiving the adhesive. The distance depends on the adhesive used and may for example be between 0.8 mm and 1.2 mm.

If, however, the spacer element 19 is formed by a peripherally formed on the base part 3, continuous circumferential collar, forms on this a circumferential bearing surface 21, which is aligned in a vertical orientation with respect to the longitudinal axis 6.

In cooperation of trained as a collar spacer element 19 with the connecting surface 5 and the surface of the component 2 is formed at a rich investment of the contact surface 21 on the surface of the component 2, a receiving chamber, in which the later the load-carrying holding or adhesive properties containing adhesive is introduced. For rapid, positionally accurate fixation is provided here that on the contact surface 21, a fast-curing adhesive is applied, with which the holding element 1 is placed together with the introduced into the receiving chamber in the region of the bonding surface 5 adhesive on the top of the component 2 and kept fixed immediately , The curing of the adhesive located in the region of the bonding surface 5 can take place subsequently. In this way, higher forces can be transmitted starting from the connecting part 4 to the component 2. The predeterminable adhesive layer thickness is determined by the distance 20 of the spacer elements 19 or the annular circumferential collar.

It is also possible to provide the previously described openings 16 in the base part 3.

FIG. 5 shows a further embodiment of the holding element 1, which may be independent of itself, wherein the same reference numerals or component designations are again used for the same parts as in the preceding FIGS. 1 to 4. To unnecessary To avoid repetition, reference is made to the detailed description in the preceding Figs. 1 to 4 or reference.

Since this retaining element 1 shown here is designed similar, as has already been described in detail in FIG. 4, reference is made only briefly to the same parts in the description and only discussed in more detail the differences.

Here, too, the holding element 1 comprises the base part 3 with the connecting part 4 connected thereto. The connection between the connecting part 4 and the base part 3 takes place in the region of the first end 7 of the connecting part 4. The connecting part 4 is again in this case as a tubular hollow body formed, in contrast to the previously described in Fig. 4 embodiment, the connecting part 4 carries an external thread. Again, this can be shaped without cutting. The connecting part 4 in turn defines the longitudinal axis 6, which is aligned in the vertical direction with respect to the connecting surface 5 of the base part 3. The second end 13 of the connecting part 4 may in turn be closed with an end wall 18 here.

Again, at least one, but preferably a plurality of spacer elements 19 is provided, which project beyond the connecting surface 5 so as to be able to determine the predetermined distance 20 between the connecting surface 5 and the surface of the component 2.

The spacer element 19 may again be formed as a continuous circumferential collar with a contact surface 21 here. The contact surface 21 in turn serves to bear against the surface of the component 2 and the preferably continuous, edge-side termination of the connecting surface 5 to form a receiving chamber for the Klebebzw described above. Connecting means.

In the base part 3, the apertures 16 described above can also be provided so as to be able to remove or transfer higher torsional forces starting from the connecting part 4 via the base part 3 to the component 2. It should be noted that the two shown in FIGS. 4 and 5 and described connection parts 4 may be formed similar, as has already been described previously in detail in FIGS. 1 and 2 and 3. For the sake of order, it should finally be pointed out that, for a better understanding of the construction of the retaining element 1, these or their components have been shown partially unevenly and / or enlarged and / or reduced in size.
