Description

Connecting element for fastening an energy store to a side sill of a motor vehicle

Technical Field

The invention relates to a connecting element for fastening an energy accumulator to a rocker beam of a motor vehicle according to the preamble of claim 1. The invention also relates to a rocker beam according to the preamble of claim 8.

Background

A plurality of such connecting elements for fastening an energy accumulator to a side sill of a motor vehicle are known from EP2468609B 1. Each of the connecting elements is designed here as a one-piece fastening bushing in the form of a sliding block, which is received and supported in a corresponding groove of the lower web of the rocker beam. In this case, a screw is screwed into a threaded opening of the respective fastening bushing, by means of which the energy accumulator is fastened to the rocker beam. However, such a retaining sleeve, which is supported only on the lower wing plate, can absorb forces only to a limited extent. It is therefore generally desirable to better secure the fixing bushing to the rocker beam.

It is of course to be taken into account here that the rocker beam according to the prior art is often configured as an undercut in the vehicle height direction (z direction) in the assembly direction which extends largely parallel to the vehicle transverse direction (y direction). This results in a relatively complex assembly, in particular when the respective fastening bushing for the energy storage device is assembled on the rocker beam, during which, for example, components of the rocker beam must be cut off in the region of the respective fastening bushing and are therefore weakened.

Disclosure of Invention

The invention is therefore based on the object of providing a connecting element for fastening an energy accumulator to a side sill and a side sill of the type mentioned at the outset, by means of which a more stable fastening of the energy accumulator to the side sill and a simpler assembly can be achieved.

According to the invention, this object is achieved by a connecting element for fastening an energy storage device to a rocker and a rocker having the features of

claims

1 and 8. Advantageous embodiments are the subject matter of the respective dependent claims.

The connecting element according to the invention comprises a fastening bushing which can be mounted on the lower web of the rocker beam and to which a fastening element, in particular a screw of an energy store, can be fastened. In order to achieve a more stable fastening of the energy store to the rocker beam and at the same time a simpler assembly, the connecting element has a further component, in particular in the form of a web, which is connected to the fastening sleeve via a corresponding connecting region in a manner adjustable with respect to the relative position thereof. By means of the two-part design with the fastening sleeve and the connecting element of the further component/intermediate wall, it is therefore possible in a simple manner to initially match the two components in terms of their relative position and subsequently join them, for example, by spot welding, laser welding or other joining methods, if appropriate also by mechanical joining methods. By means of the two parts, it is firstly possible in a simple manner to connect the respective connecting element to the component of the rocker arm to a large extent, so that an extremely stable connection of the energy storage device to the rocker arm is possible. The adjustability of the connecting element thus allows the fastening sleeve, on which the bottom energy store is fastened, to be easily connected to the associated reinforcement part of the side sill beam in a significant height extension by the associated support element, in particular the bulkhead.

Furthermore, tolerance compensation can be achieved in a simple manner by adapting the connecting element, for example, in the vehicle height direction (z direction) and/or in the vehicle transverse direction (y direction), which considerably simplifies assembly. Furthermore, the two-part construction also makes it possible to use the connecting element in a rocker configured as an undercut, which again has the advantage that the components of the rocker do not have to be cut off in the region of the connecting element.

In an advantageous embodiment of the invention, the further component of the connecting element is designed as a bulkhead which can be connected to a further component of the rocker beam, in particular a reinforcement part. Such a bulkhead is particularly simple to construct, can be easily connected to the fastening bushing, and furthermore is connected to the corresponding component of the rocker side in large dimensions, so that a particularly advantageous and stable fastening of the energy accumulator to the rocker side as a whole can be achieved.

In a further advantageous embodiment of the invention, the fastening bushing and the further component, in particular the intermediate floor, are adjustable relative to one another with respect to their relative position with reference to their installation position in the transverse direction of the vehicle (Y direction) and/or in the height direction of the vehicle (z direction) before being connected to one another. A connecting element is thus proposed which can be fixed to the rocker beam in an optimum manner while compensating for corresponding tolerances.

It has furthermore proven to be advantageous if the respective joining regions of the securing sleeve and the further component/intermediate wall are designed as flat surfaces, as a result of which a particularly simple and easily repeatable adjustment of the securing sleeve and the further component/intermediate wall is achieved.

In a further advantageous embodiment of the invention, the retaining sleeve is designed as a cold-extruded part, which enables a simple production method and opens up good connection possibilities with other components/separating walls, which are usually designed as sheet steel components.

In a further advantageous manner, the fastening sleeve and the further component/spacer are connected to one another by a joint connection, in particular by spot welding. This joining method can be implemented particularly easily during assembly.

In a further advantageous embodiment, the fastening bushing has a head, by means of which the fastening bushing can be supported on the lower web of the rocker. This results in a particularly stable fastening of the fastening sleeve to the lower wing.

A rocker beam for an automobile is also provided, which has an inner rocker member, a lower wing plate and an outer rocker member, by which a cavity of the rocker beam is defined. A reinforcement member is disposed in the cavity and is fixed to the rocker inner member. The rocker beam has at least one connecting element according to any one of claims 1 to 7. The advantages that can be achieved by the at least one connecting element are the same as those obtained for a rocker beam.

In this case, it has proven to be particularly advantageous if the lower wing panel and the reinforcement part, which are connected to one another via at least one connecting element, are designed as a pre-assemblable, structure-specific structural unit. The lower wing and the reinforcement part as part of the structural unit that can be preassembled can thus be specifically adapted to the structural design of the motor vehicle. Thus, for example, a structural unit consisting of a lower wing and a reinforcement for a vehicle having a bottom energy store can be realized, which structural unit is supplemented, for example, with corresponding connecting elements for connecting the energy store to a side sill, while a structural unit for a motor vehicle having a combustion drive can be provided, which structural unit is of comparatively simple construction. The rocker beam can thus be matched in a simple manner overall to the respective design of the motor vehicle, wherein the respective design relates in particular to the drive design but, if necessary, also for example to the vehicle vertical height of the motor vehicle (sedan, dirtbike, lorry, coupe, convertible, etc.).

Further features of the invention emerge from the claims, the figures and the description of the figures. The features and feature combinations mentioned above in the description and those mentioned in the following description of the figures and/or shown only in the figures can be used not only in the respectively specified combinations but also in other combinations or alone.

Detailed Description

Fig. 1 shows a partial perspective view of a body of a passenger car, in which a floor assembly 1 is visible in particular, on the outside of which a side wall 2 is provided which extends in the longitudinal direction of the vehicle (x direction) or in the height direction of the vehicle (z direction), but only the inner side wall parts 3 of the side walls are visible here. An intermediate and an outer side wall part are connected to the inner side wall part 3 on the outside. Visible in the side wall 2 or the side wall part 3 are a front door opening 4 and a rear door opening 5, as well as door pillars in the form of a-pillars 6, B-pillars 7 and C-pillars 8.

On the left side of the vehicle (viewed in the forward driving direction) a rocker 9 can be partially seen, which extends at least substantially between a front wheel house 11 and a rear wheel house 12. The rocker 9 here comprises an inner rocker 10 which in the present case extends at least substantially likewise from a front wheel house 11 to a rear wheel house 12, which inner rocker is in the present case fastened to the floor assembly 1 or to the side wall part 3 in the interior of the side wall 2.

Furthermore, the rocker beam 9 comprises a lower web 13 which delimits the rocker beam downwards in the vehicle height direction (z-direction) and extends substantially horizontally in the vehicle transverse direction (y-direction) and in the vehicle longitudinal direction (x-direction), and a reinforcement part 14 which is substantially hat-shaped in cross section and which is accommodated in a cavity formed by the rocker beam 9 in a manner which will be described in more detail below. The lower web 13 is here constructed separately from the rocker inner 10 in a manner which will be described in further detail and is connected to the rocker inner 10 by means of a reinforcement part 14 along a flange connection which extends in the longitudinal extension of the rocker 9. Furthermore, the lower web 13 and the reinforcement part 14 form a structural unit 15 which can be preassembled and is specific to the design, which is described in more detail with reference to fig. 2a to 2c, and which is first produced separately from the floor assembly 1 and is finally fastened to the floor assembly 1 or to the rocker inner part 10.

The assembly of the pre-assembled, design-specific structural unit 15 will now be explained with reference to fig. 2a to 2 c:

fig. 2a shows, for this purpose, a reinforcement part 14 and corresponding

webs

16, 17 in a corresponding perspective view, which webs (as shown in fig. 2 a) are connected to the reinforcement part 14, for example, by spot welding, laser welding or similar joining methods, optionally also by means of a mechanical connection. The separating walls 16 are arranged distributed over the reinforcement part 14 in the longitudinal direction, namely in the corner regions between the vertically extending wall regions 19 and the substantially horizontally extending wall regions 20. The bulkheads 17 constitute respective front and rear closure members of the side sill 9. If necessary, in particular, jack receptacles can also be fastened in the front and rear regions of the rocker beam 9. The reinforcement member 14 is made, for example, by roll forming.

Fig. 2b shows a schematic representation of a further method step for producing the pre-assemblable structural unit according to fig. 1 in a corresponding perspective view, in which corresponding fastening sleeves 21 are provided for fastening the bottom energy store to the motor vehicle, which are fastened, for example, by spot welding, to the upper side of the lower web 13 of the pre-assemblable structural unit 15. The fastening sleeve 21 is produced here by cold extrusion and comprises a head 22 and a shank 23 connected integrally thereto. Threaded bores 39 (fig. 7) are introduced into the respective retaining sleeves 21, in which threaded bores screws 38 (fig. 7) for fixing the energy store 37 (fig. 7) can be fixed. The threaded hole 39 is provided so as to overlap with the opening in the lower wing plate 13.

Fig. 2c shows a corresponding further perspective view of the reinforcement part 14 with the separating

walls

16, 17 according to fig. 2a and the lower wing 13 with the fastening sleeve 21 according to fig. 2b, which are connected to one another in a further method step to form a complete preassembled structural unit. The webs 16 on the sides of the reinforcement part 14 and the associated retaining sleeves 21 on the sides of the lower wing 13 are connected to one another here by spot welding, if appropriate also by other joining methods. Each pair (consisting of the respective intermediate wall 16 and the associated retaining sleeve 21) forms a connecting element 24, by means of which the reinforcing part 14 and the lower wing 13 are connected to one another. The lower wing 13 and the reinforcing part 14 are thus connected to one another by a plurality of connecting elements 24 of the pre-assemblable structural unit 15.

With reference to fig. 6, which shows a perspective view of a two-part connecting element 24, which is formed by the respective retaining bushing 21 and the associated intermediate wall 16 and by means of which the lower wing 13 and the reinforcement part 14 are connected to one another, it can be seen that both the respective intermediate wall 16 and the associated retaining bushing 21 each have a respective joining

region

25, 26 which has a planar surface extending vertically in the vehicle height direction (z direction) and in the vehicle transverse direction (y direction), respectively, or is formed as such. Along these surfaces or joining

regions

25, 26, the respective intermediate wall 16 and the associated retaining sleeve 21 can be adjusted in their position relative to one another, in particular in the vehicle height direction (z direction), but also in the vehicle transverse direction (Y direction), i.e. in their relative position to one another. After the adjustment, the intermediate wall 16 and the associated retaining sleeve 21 are joined, for example, by spot welding. These method steps are all carried out within the scope of preassembly of the structural unit 15.

Furthermore, the lower panel 13 and the reinforcement part 14 are also directly connected to each other, i.e. along a flange connection 27 extending in the longitudinal extension of the side sill beam. The respective flanges are connected by laser welding, wherein other joining methods are also conceivable.

As can be seen from the perspective exploded view above fig. 3, the rocker inner part 10 is welded to the floor assembly 1 within the scope of body-in-white manufacture. According to the lower illustration in fig. 3, the prefabricated, structure-specific structural unit 15 is first connected to the side frame intermediate 42 according to arrow 43, whereby the side frame intermediate 42 is connected on the inside to the inside of the side frame not shown here and also to the outside of the side frame not shown here. The side frame middle 42, the side frame inner and the side frame outer (which can each be designed in one piece or in multiple pieces) thus form a side frame or a side wall of the vehicle body. The side frame outer part here forms a rocker outer part 41 visible in fig. 7 in the region of the rocker 9.

The side frame with the structural unit 15 is then fixed to the floor assembly 1 with the rocker inner 10.

Fig. 4 shows, in a partial perspective view, once again in isolation, the assembly of a prefabricated, structure-specific structural unit 15 with a rocker inner part 10 arranged fixedly on a side face of the floor assembly 1.

In connection with fig. 5 (which shows a partially shown perspective and greatly enlarged sectional view of the rocker 9 in relation to fig. 4) or in connection with fig. 7 (which shows a sectional view of the entire rocker 9 seen from the front), it can be seen in particular that the lower panel 13 is indirectly connected to the rocker inner 10 by means of a reinforcement part 14. This indirect connection between the lower web 13 and the rocker inner part 10 is achieved in particular by a lower flange 28 of the reinforcement part 14, which is hat-shaped in cross section and visible in fig. 5 and 7, which connects an upwardly angled flange 29 of the lower web 13 to a lower end region or flange 30 of the rocker inner part 10. The connection between the flange 28 of the reinforcing part 14 and the flange 29 of the lower wing 13 forms the above-described flange connection 27, which is produced within the scope of the preassembly of the structural unit 15.

By means of spot welding, in the manufacture of a body in white, on the one hand, the flange 28 of the reinforcement part 14 is connected to the flange 30 of the rocker inner 10 to form a flange connection 31 extending in the longitudinal direction of the rocker 9, i.e. at least substantially horizontally and in the vehicle longitudinal direction (x direction), and thereby an indirect connection is established between the lower wing plate 13 and the rocker inner 10. On the other hand, the upper flange 33 of the reinforcement member 14 in the upper region is connected to the rocker inner 10 along a flange joint 32 that extends also horizontally and in the vehicle longitudinal direction (x direction).

Also visible in fig. 7 is a rocker outer 41 that is connected to the flange 34 of the rocker inner 10 with an upper flange 45. In the outer region of the lower portion of the rocker 9, the rocker outer 41 is connected to the flange 35 of the lower panel 13 via a flange 46. The rocker outer 41 thus defines, together with the rocker inner 10 and the lower panel 13, a cavity 36 of the rocker 9 in which the reinforcement member 14 and the connecting element 24 are also disposed between the reinforcement member 14 and the lower panel 13.

Furthermore, it is clear from the overview of fig. 6 and 7 in which way the height extension of the respective connecting element 24 in the vehicle height direction (z direction) is adapted. In this case, the respective

joint regions

25, 26 of the respective bulkhead 16 and of the associated fastening bushing 21 are visible, which lie flat against one another and along which the bulkhead 16 and the associated fastening bushing 21 can be adjusted in terms of their position relative to one another vertically in the vehicle height direction (z direction) and in the vehicle transverse direction (y direction). However, the method steps are carried out within the scope of preassembly of the structural unit 15.

Fig. 5 and 7 also make clear how the bottom energy storage 37 for the electric drive of the motor vehicle is fastened to the respective side sill 9. This is achieved by means of corresponding screws 38, which are screwed into corresponding associated threaded bores 39 of the respective retaining sleeves 21.

In order to achieve a positionally precise arrangement of the bottom energy store 37 relative to the side sill 9, reference elements, in particular delimiting openings 40, which can be seen in fig. 2b and 2c, are provided in the lower wing 13 for orienting the energy store 37. The delimiting opening 40 is therefore already provided when the structural unit 15 is preassembled, so that the connecting element 24 can be oriented thereon in order to keep the respective tolerance chain particularly small.

The rocker inner part 10 and the lower panel 13 are formed from different materials, wherein the rocker inner part 10 is formed in particular from a high-strength or highest-strength steel, and the lower panel 13 is formed in particular from a steel material that is relatively ductile. The rocker inner 10 may be formed of a galvanized member press-hardened in direct hot forming, if necessary.

Fig. 8 shows a perspective exploded view of a preassembled structural unit 15 according to a further embodiment, in which the height of the connecting elements 24 (which comprise the respective retaining sleeves 21 and the associated separating wall 16) is first adjusted and the connecting elements are connected to one another and to the reinforcing part 14 before they are additionally connected to the lower wing 13. In other words, the fastening sleeve 21 and the associated intermediate wall 16 are oriented at a desired height/position relative to one another and engage with one another and are also connected to the reinforcing element 14. The order of the method steps can be changed if necessary. It is therefore conceivable to first fix the respective retaining sleeve 21 to the reinforcing part 14 and then to orient and fix the associated separating wall 16 on the respective retaining sleeve, or to first orient and connect the retaining sleeve 21 and the associated separating wall 16 to one another and then to fix the connecting element 24 provided in this way to the reinforcing part.

However, it is essential for the present embodiment of the structural unit 15 that the lower wing plate is connected to the reinforcement part 14 (via the flange connection 27) or the connecting element 24 only after the aforementioned method steps.

Fig. 8 shows, analogously to fig. 5, a perspective sectional view of the rocker 9 in an alternative embodiment, in which the respective fastening bushing 21 of the energy accumulator 37 projects through the lower wall region 20 of the reinforcement part 14 and is connected to the associated bulkhead 16, which is itself arranged in the cavity 47 defined by the reinforcement part 14 and the rocker inner part 10. In the present case, the respective intermediate wall 16 and the associated retaining bushing 21 also each have a respective joining

region

25, 26 which has a surface extending vertically in the vehicle height direction (z direction) and in the vehicle transverse direction (y direction), respectively, or is formed as such. Along these surfaces or joining

regions

25, 26, the respective intermediate wall 16 and the associated retaining sleeve 21 can be adjusted in their relative position to one another, in particular in the vehicle height direction (z direction), but also in the vehicle transverse direction (Y direction). After the adjustment, the intermediate wall 16 and the associated retaining sleeve 21 are joined, for example, by spot welding.

These method steps can also be carried out in the present case within the scope of the preassembly of the structural unit 15. The lower wing 13 is again designed separately from the reinforcement part 14 and is connected to the reinforcement part 14 by means of a flange connection 27. Here, the lower panel 13 is also constructed separately from the rocker inner 10 and is connected to the rocker inner by means of the reinforcement member 14 via the flange connection 31.

Fig. 10 finally shows an alternative embodiment of the rocker beam 9, in which different types of pre-assemblable, structure-specific structural units 15 are provided, which structural units 15 are used in passenger cars which operate purely on fuel. Since the connecting element 24 is not required here for connecting the energy store 37, all of the intermediate wall 16 and the fastening sleeve 21 and the rear pair are omitted here, so that the lower wing 13 and the reinforcement part 14 are connected to one another only by this connecting element 24. However, the flange connections between the lower wing plate 13 and the reinforcement member 14 (within the scope of pre-assembly of the structural unit 15) and between the structural unit 15 and the rocker inner 10 are substantially the same as in the previous embodiment.

Overall, a modular system is therefore to be seen, in which the lower panel 13 or the structural unit 15 can be adapted in a simple manner to the structural design specifically (depending on the driving mode of the vehicle in this case) and preassembled and then connected to the rocker inner part 10 of the lap-joint structural design, in order to achieve the desired simple, cost-effective and on-demand change of the structural design between different vehicle configurations.
