Description

Technical field

The invention relates to a node for installing a wing in a bearing element of a body body in a motor vehicle, wherein a deformation element is located between the wing and the specified bearing element in such a way that it extends in the longitudinal length of the wing and is connected to the latter, while the connecting part of the deformation element filling the gap between the wing and the supporting element has a panel structure and extends in the longitudinal length of the wing.

State of the art

A node of this type is known from document US 2006/0113825 A1. In the case of this node, the deformation element is formed by the panel part of the structure with many angles and reinforcing elements connected to the panel part. The panel part is inclined at right angles in the region of one end and connected there with the wing, while the panel part and the wing form one component. In the region of the other end of the panel part, which is facing away from the wing, the panel part is inclined in the opposite way at an angle of 90 ° and the flange part formed in this case has various holes for holding the fixing screws for fixing the panel part to the element. Various reinforcing elements are located between the holes in the flange. These reinforcing elements fit snugly against the flange and are connected to a partition of the panel portion that extends between the portion of the flange and the sloping side of the wing of the panel portion. The specified partition has a greater length in the vertical length of the vehicle than the length of the flange or the inclined part of the panel part in the transverse length of the vehicle. This design of the node with the deformation element is very complex in terms of manufacturing and production. Thus, the deformation element consists of a panel part, which has a design with many angles and to which reinforcing elements are attached. The formation of a deformation element from these two different functional groups, firstly, a thin-walled panel part and, secondly, reinforcing elements installed in partial areas of the panel part, leads to the creation of a complex nature of the deformation of the deformation element in the event of a shock on a motor vehicle wing area. Accordingly, the deformation of the deformation element during the impact cannot be unambiguously predetermined.

A deformation member for mounting a wing in a vehicle member is also known from DE 602004008372 T2. The specified deformation element in a similar way has a complex structure and a complicated ribbed structure, while the ribs are deformed in the case of impact of a person on the wing.

The installation of a wing in an element by means of a deformation element is also described in DE 102008010138 A1. The deformation element in this case has a panel structure and a U-shaped cross section. The specified deformation element with a structurally simple design has the disadvantage that it can be deformed even if efforts that are not targeted are applied to the wing, for example, if a person leans against the wing in the region of the upper end or sits on the wing and, therefore will apply increased force to the wing.

Disclosure of invention

The aim of the present invention is to develop a node mentioned at the beginning of the type so that the specified node, firstly, provided sufficient deformation ability in the event of impact of a person and, secondly, provided sufficient shape stability when installing the wing. This functionality should be provided in the case of a structurally simple design and simple production of the deformation element.

The goal is achieved through the site, which is designed in accordance with the characteristics of paragraph 1 of the claims.

In the case of the assembly according to the invention, it is therefore ensured that this part of the deformation element, which fills the gap between the wing and the element, has a wavy structure in a plane that is perpendicular to the length direction of the connecting part between the wing and the supporting element.

Filling said gap with a deformation element can therefore be done in a very simple way by using a flat starting material in the form of a panel deformed in a wavy manner.

Due to the design of the deformation element in accordance with the invention, it is quite resistant to loads that are lower than the shock loads of a person relative to the wing, but sufficiently deformable in the event of a shock of a person on the wing.

The deformation element is made structurally in a particularly simple way, if the specified deformation element is formed by the connecting part of the wavy structure, part of the flange connected to the wing, and part of the flange connected to the supporting element. Therefore, the deformation element consists only of parts of the flange and part of the corrugated structure located between these parts of the flange.

It is considered particularly advantageous if the deformation element, in particular, the part of the flange on the wing side, is rigidly connected to the wing, in particular, is connected by means of riveted joints. In the case of joining by means of riveted joints, an advantage should be noted in that prior to placing rivet joints, it is possible to precisely align the deformation element and the wing, in particular from the point of view of compensating for inaccuracies in production and / or assembly.

The deformation element, in particular a part of the flange from the side of the supporting element, is preferably removably connected to the supporting element, in particular by screw connections. It is believed that the advantage of this detachable connection is that in case of damage to the wing, the specified wing together with the deformation element can be removed from the element in a simple way.

The wavy shape of the connecting portion of the deformation element is preferably periodically formed. In particular, the connecting portion has many wave peaks and wave troughs.

From the point of view of a suitable application of deforming forces to the deformation element and simple assembly of the deformation element, in particular, if the latter is integral with the wing, it is considered preferable if the connecting part is located at an angle α ≠ 90 °, in particular at an angle α> 90 °, relative to parts of the flange connected to the supporting element. It is also considered preferable if the connecting part is located at an angle β ≠ 180 °, in particular, an angle β <180 °, relative to the part of the flange connected to the wing. Therefore, the corresponding option prevents the corresponding part of the flange from being located at right angles to the connecting part, and therefore, the forces transmitted between the parts of the flange are not perpendicular, but inclined, in particular, at a slight inclination, due to the correspondingly inclined arrangement of the connecting part relative to the parts of the flange. Moreover, the corresponding screw connection is easily accessible in the region of the indicated part of the flange.

Particularly advantageous is considered if the connecting part is located essentially vertically relative to the horizontal position of the vehicle.

In accordance with a specific embodiment of the invention, it is proposed that the connecting part of the deformation element be equipped with a plurality of passages and / or sides. The longitudinal bending resistance of the connecting part is reduced as a result of the formation of the connecting part with many passages. If the connecting part is equipped with flanges, the rigidity of the connecting part is increased in the region of said flanges, as a result of which the regions of the connecting part have low stiffness between adjacent flanges. By means of a specific arrangement and a certain size of a plurality of passages and / or sides in the connecting part of the deformation element, a permanent influence on the deformation nature of the deformation element can be provided.

The connecting part is preferably equipped with passages, since these passages or holes in the connecting part as a whole are easier to perform than to run the beads in the connecting part.

According to the development, a connecting part is proposed having variously designed aisles or sides, in particular variously designed pairs of aisles or sides, so that they extend in the longitudinal extent of the wing and / or in such a way that they extend in the direction of extension the connecting part between the wing and the supporting element. By this, the deformation nature of the connecting part can also be modified, also from the point of view of sufficient stiffness of the deformation element. For example, deformation in the case of exposure to a relatively small force may be preferable in some areas of the deformation element, for example, in areas of the wing, which, in particular, must withstand the impact of a person with a small body weight, in particular, a child. It is advantageous if the deformation element is deformed in this area under the influence of less force than in other areas of the deformation element, in the area in which the impact point of an adult should mainly be the starting point.

From the point of view of the influence on the deformation behavior, on the one hand, and the strength of the deformation element, on the other hand, it is considered preferable if the passages and / or sides have a straight, and / or curved, and / or rhomboid shape. Passages or sides in this case can be located in different ways. In particular, the passages and / or sides of a rectilinear or curvilinear shape are arranged in such a way that they extend essentially in the longitudinal extent of the wing.

From the point of view of the wavy configuration of the connecting part between the wing and the supporting element in accordance with the invention, it is considered preferable in accordance with the development of the invention if the passage and / or the side or the arrangement of the passages and / or sides is located in the region of the corresponding wave cavity of the corrugated connecting part and otherwise constructed passage and / or otherwise designed runway or otherwise constructed passage arrangement and / or otherwise designed runway arrangement ortikov located in the region of the peak of the wave of the part, which is located next to the specified trough of the wave.

The deformation element and the wing can be made of various materials. It is considered preferable if the deformation element is made of metal, in particular aluminum. The deformation element may also be made of plastic. In relation to a wing, it is considered preferable if said wing is made of metal, in particular aluminum. The wing can also be mainly made of plastic.

Additional advantages of the invention arise from the dependent claims, the accompanying drawings, and descriptions of preferred, exemplary embodiments reproduced in the drawings, but not limited to.

The implementation of the invention

An exemplary embodiment of FIG. 1-3 represents a node 1 in accordance with the invention for installing the wing 2 in the supporting element 3 of the body body in a motor vehicle. The body element 3, in particular, is a longitudinal load-bearing element, and the motor vehicle, in particular, is a passenger vehicle. In addition to the wing 2 of the assembly 1 and the supporting element 3, a part of the assembly 1 is formed by a deformation element 4, which is connected to the wing 2 and the supporting element 3. The deformation element 4 extends in the longitudinal extent of the wing 2 and the longitudinal supporting element 3. This is illustrated by the arrow X on FIG. 1. The indicated arrow X extends perpendicular to the plane of the sheet in accordance with FIG. 3.

The wing 2 and the deformation element 4 are made of metal, in particular aluminum. The supporting element 3 is made of metal.

The deformation element 4 has a connecting part 5, which fills the gap between the wing 2 and the supporting element 3. Part 5 has a panel structure. The specified panel part 5 also extends in the longitudinal extent of the wing 2. The deformation element 4 is formed by the specified part 5, part 6 of the flange connected to the wing 2, and part 7 of the flange connected to the supporting element 3. Part 6 of the flange is rigidly connected to the wing 2 in the region downwardly inclined panel portion 8 by means of rivet joints. Part 7 of the flange of the deformation element 4 with the possibility of removal is connected to the element 8, namely with the upper panel part 9 of the element, which has a U-shaped cross section through screw connections. To accommodate the fixing screws, the flange portion 7 of the deformation element 4 in this case has a plurality of holes 10 located one after the other in the longitudinal direction of the deformation element 4. Part 9 of the bearing element 3 is provided with holes so that they correspond to the indicated holes 10. The deformation element is attached to to the supporting element 3 by means of a conventional screw and nut connection or by connecting a screw and a blind rivet nut. Such a blind rivet nut 11 is illustrated in FIG. 3 before placing it in place. Screws for connecting the deformation element 4 and the supporting element 3 are not shown.

As can be understood, in particular, from the illustration shown in FIG. 3, part 5 is located at an angle α> 90 ° relative to part 6 of the flange connected to the supporting element 3. The specified angle is slightly more than 90 °. It can also be understood from FIG. 3 that part 5 is located at an angle β <180 ° relative to part 6 of the flange connected to the wing 2. This angle is slightly less than 180 °. This angular arrangement of the flange parts 6 and 7 with respect to the connecting part 5 allows free access to the screw joints used to secure the deformation element 4 and the supporting element 3. In this case, the connecting part 5 is located essentially vertically relative to the vertical position of the vehicle. This vertical arrangement can be understood, in particular, from the illustration shown in FIG. 3.

The connecting part 5 has a wavy structure and in this regard, reference is further made to the illustration shown in FIG. 4 and 5, for the following more detailed description with respect to a further exemplary embodiment. In particular, the connecting part 5 of the deformation element 4 has a wavy structure in a plane that is perpendicular to the length direction of the connecting part 5 between the wing 2 and the supporting element 3. This wavy shape can be understood, in particular, when considering the bottom view of the deformation element 4 in accordance with the illustration shown in FIG. 5. It shows that the waveform of part 5 is periodic. The waveform can be understood from the illustration shown in FIG. 1 and 2.

In an exemplary embodiment of FIG. 1-3, the connecting part 5 is equipped with various passages 12. The latter are arranged obliquely relative to the vertical and are designed in such a way that they extend in a straight line. In accordance with the illustration shown in FIG. 2, the upper passages pass from top to bottom from right to left, while the lower passages 12 are more inclined than the upper passages 12, and the lower passages 12 pass from top to bottom from left to right. The length of the two upper passages 12 exceeds the length of the remaining passages 12. The arrangement or arrangement of the four passages 12, which are illustrated in FIG. 2 is repeated many times over the entire length of the deformation element 4. By means of the waveform of part 5, a certain intrinsic strength of the deformation element 4 can be achieved, and by introducing a certain number of passes 12 of a certain shape and setting passages, points of reduced strength can be obtained in a targeted manner in the region of the part 5 and, therefore, the deformation element 4.

Exemplary embodiments that are an alternative to the embodiment of the deformation element shown in FIG. 1-3 are illustrated in FIG. 4-8.

An exemplary embodiment of FIG. 4-5 represents a deformation element 4, in which part 5 has a plurality of elongated rectilinear passages 12 oriented substantially longitudinally. In this case, five arrangements 13 of the passages 12 are made, wherein each arrangement 13 consists of three passages 12. Two different arrangements 13 are made, which are arranged alternately. One arrangement 13 with three passages 12 extending substantially horizontally, the upper passage 12 being longer than the central passage 12 and the last longer than the lower passage 12, is located in the wave valley region of the connecting part 5 of the deformation element 4. Another arrangement 13, which consists of passages 12 which have the same length and the same curvature and extend substantially horizontally, is located in the region of the corresponding wave peak of part 5.

In an exemplary embodiment of FIG. 4, two arrangements 13 of the passages 12 are again provided in the region of part 5 of the deformation element 4. One arrangement 13 has two passages 12 that are of the same length, extend straightly, are located in the region of the corresponding wave depression and are slightly inclined relative to the vertical. Another arrangement 13 has four shorter passages 12, of which two lower passages that are parallel to each other extend substantially parallel to the passages 12 of the first arrangement 13, while the other two passages 12 of this arrangement 13 formed of four passages 12, in a similar manner have a very short construction and extend substantially at right angles to two other passages 12 of this arrangement 13. The corresponding arrangement 13, consisting of four passages 12, is located in the wave peak region of part 5.

In an exemplary embodiment of FIG. 7 again, two arrangements 13 are provided, which are arranged alternately and have passages 12. One arrangement 13 has an arrangement 13 described with respect to the embodiment in accordance with FIG. 6, with four short passages 12, which in turn are located in the region of the peak of the wave. In an exemplary embodiment of FIG. 7, the arrangement 13 of the passages 12 is in each case provided in the region of the trough of the wave. The corresponding arrangement 13 is formed by three passages 12, of which the corresponding upper and lower passages extend substantially horizontally and the passage 12 located between them is inclined relative to the horizontal. The passages 12 of this arrangement 13, consisting of three passages 12, are longer than the passages 12 of another arrangement 13 formed of four passages 12.

In an exemplary embodiment of FIG. 8, two arrangements 13, which are arranged in an alternating manner, are in turn provided in part 5, with the corresponding diamond-shaped passage 12 passing through part 5 in the region of the wave trough. The length of the diamond-shaped passage 12 in the vertical direction exceeds the length in the horizontal direction. An arrangement 13 of two passages 12 is provided in the region of the corresponding peak of the wave, wherein said passages 12 are particularly long and extend substantially horizontally.

The invention is not limited to one deformation element 4 extending between the wing 2 and the supporting element 3, in particular over the entire separation area of the wing 2 and the supporting element 3, in the assembly 1. In this way, a plurality of deformation elements 4 between the wing 2 and the supporting element 3 can be provided. while these deformation elements are located, in particular, at a certain distance from each other, relative to the longitudinal extent of the wing 2 and the supporting element 3.

Such an embodiment of the deformation element 4 is illustrated in FIG. 9, while the deformation elements 4 located one after another are located in the longitudinal extent of the wing 2 and the supporting element 3. The deformation element 4 shown in FIG. 9, is designed as a short compact component with parts 6 and 7 of the flange and part 5 connecting these parts of the flange, with various passages 12 made in part 5. Part 6 of the flange, which must be riveted to the wing 2, in this case also equipped with part 14 corresponding to the waveform of part 5. The rivet points, in the region of which the deformation element 4 is connected to the wing 2, are indicated by the reference number 15.
