    DESCRIPTION
    The present invention relates to a body part of a vehicle and an assembly component for use in such a body part.
    It is known that a vehicle has individual body parts which constitute the bodywork of the vehicle. Such bodywork parts are often made of several parts and in particular have structural components. It is also known to provide special deformation components with the structural components, which, in the event of a collision, absorb or reduce energy by their deformation and thus constitute a passive protection function for the driver of the vehicle.
    The problem in known bodywork parts is that the connection between the structural components and the deformation components is relatively complex. In particular, this assembly must also withstand a collision so that the corresponding energy reduction by the deformation of the deformation component is indeed possible. For this, a large effort is usually required to ensure the attachment between the deformation component and the structural component with the necessary security. In addition to this high construction effort, it is necessary to count accordingly with a high weight and a great complexity. The object of the present invention is to overcome at least in part the disadvantages described above economically and simply. In particular, the object of the present invention is to allow in an economical and simple way to reduce the stress applied to the assembly area, so that one can obtain a reduction in the complexity and / or the weight of the body part while maintaining or even improving safety. The above-mentioned object is achieved by a body part of a vehicle having a structural component and a deformation component, an assembly component being fixed at an end portion of the deformation component, with a surface contact member for contacting a mating contact surface of the structural component, characterized in that between the contact surface and the mating contact surface a normal spacing is formed and the joining component is constructed to create, in the event of a collision, a force-transfer contact between the contact surface and the mating contact surface, as well as an assembly component for assembling a deformation component and a structural component to provide a body part according to the invention and having a contact surface for contact with a mating contact surface of the structural component. Other features and features of the invention result from the description and the drawings. In this case, the characteristics and details which are described in relation to the bodywork part according to the invention are obviously also valid in conjunction with the assembly component according to the invention and vice versa, so that reference will be made to or that one can always refer interchangeably to the individual aspects of the invention in the context of the disclosure.
    According to the invention, there is now provided a bodywork part of a vehicle which has a structural component and a deformation component. An assembly component is attached at an end portion of the deformation component, with a contact surface for contacting a mating contact surface of the structural component. A bodywork part according to the invention is characterized in that between the contact surface and the mating contact surface is made a normal spacing. In addition, the assembly component is designed to create, in a collision, a force transfer contact between the contact surface and the mating contact surface.
    It is also provided according to the invention now that at least two different positions can be adopted using the assembly component. In a normal case, in a situation of normal use of the vehicle, the mating contact surface and the contact surface are therefore separated from each other by the normal spacing. The contact surface and the conjugate contact surface are therefore preferably not in contact in this normal case. If now a deformation is initiated in the bodywork part, that is to say that an oversized force and exceeding the normal case is exerted, a deformation first begins with a relative movement of the assembly component by relative to the structural component. The contact surface thus overcomes the normal spacing and comes into contact with the mating contact surface in such a collision case.
    By bringing the contact surface into contact with the mating contact surface in the event of a collision, the total surface area between the structural component and the deformation component for force transfer increases. In this case, there is then an increased force transfer surface, so that all the force transfer surfaces are exposed to less stress than in the case of a single force transfer through an assembly between the deformation component and the structural component. Contacting the contact surface with the conjugate contact surface and the resulting increase in the force transfer surface therefore directly leads to a discharge of the transfer of force between the deformation component and the structural component. The deformation component and the structural component can in this case be connected separately to one another in a very different way. A simple plug-in is in this case sufficient. However, it is also possible to provide bonded joints, welded joints, plug-in assemblies, screwed joints or riveted joints within the meaning of the present invention, as will be further explained in more detail below.
    By providing additional crash support functionality and a corresponding protection function for the assembly functionalities between the structural component and the deformation component, this attachment between the structural component and the deformation component, available separately from the assembly component, is thereby discharged and protected.
    This results in a force transfer assembly provided for a normal case between the structural component and the deformation component can be made much simpler and with less complexity because it must provide essentially only for the normal case the functionality of force transfer necessary. In the event of a collision, the additional force transfer available between the contact surface and the mating contact surface, after having overcome the normal spacing, favors the force transfer assembly already engaged between the structural component and the deformation component, so that with this support, the reduced mechanical stability of this assembly is no longer a factor to consider in the event of a collision. This means that, in addition to reduced complexity and reduced weight, even a further improvement and an increase in the safety of the total assembly between the structural component and the deformation component can be achieved even in the event of a collision. .
    In this case, the assembly component is preferably attached to the deformation component with force transfer. Thus, in a collision, the desired force transfer through the contact surface to the mating contact surface can be ensured. The assembly component by the occurrence be made separately or in one piece with the deformation component. As will be further explained below, a separate embodiment of the assembly component is, however, associated with certain advantages.
    A deformation component, within the meaning of the present invention, is a component that deforms as part of a collision body part to absorb energy. Such deformation components, within the meaning of the present invention, have in particular the deformation properties defined and explained further below. Thus, in this way in particular, the protection of other body parts, in particular of the structural component against a corresponding deformation is provided in case of collision. The deformation components according to the present invention are preferably designed to have a high energy absorption during deformation.
    The structural component may in particular be a steel component. Thus, for example, one can think of a steel crank or other structural component carrying the body within the meaning of the present invention. The deformation component may for example be in the form of a spun section, which in particular has aluminum. The ribs therein may provide a desired type of deformation or a desired deformation direction of such a spun section of the deformation component.
    It may be advantageous, in the case of a bodywork part according to the invention, that the contact surface and the mating contact surface are made for plane contact with each other. This means that the two surfaces, i.e., the contact surface and the mating contact surface, can provide a planar force transfer with each other. If the contact surface and the mating contact surface are in the form of flat surfaces, they are therefore preferably arranged parallel to each other both in the case of normal spacing and in the case of the position in contact. In addition to simple flat surfaces, it is also possible to design more complex surfaces or curved surfaces for the contact surface and the mating contact surface. The contact surface and the mating contact surface are preferably configured in a complementary manner to achieve the flat contact advantageously provided according to this embodiment. This results in significantly improved force transfer because the desired force transfer can be performed over a larger area.
    It is furthermore advantageous, in a bodywork part according to the invention, for the deformation component to overlap, at or in its end portion, with the structural component. By this is meant that the deformation component with the end portion is at least partially plugged into the structural component. Thus, for example, the structural component may have a C-shaped cross section into which a corresponding hollow spun section of the deformation component is driven. The overlap may occur partially or completely in the peripheral direction. Thus, a C-section previously described may for example be provided with a cover plate for the structural component for a closed cross-section. In such a case, the deformation component is provided with a portion of complete overlap in the peripheral direction. Due to penetration, additional support against transverse forces is provided. In addition, the normal spacing described between the contact surface and the mating contact surface is protected against soiling or other obstacles.
    An additional advantage may be, in the case of a bodywork part according to the invention, that the assembly component is made separately from the deformation component. The separate embodiment makes it possible to optimize the deformation component in terms of economical and simple manufacturing. In particular, spinning forming functionality can now be provided so that the deformation component can be formed as a spun section. As it is possible in particular to provide a hollow spun section, in addition to a reduction in the costs and complexity of manufacturing the deformation component, it is also possible to obtain a weight reduction of this deformation component.
    It is furthermore advantageous, in a bodywork part according to the invention, for the structural component to be assembled to the deformation component independently of the assembly component. This leads to a force transfer already described in the introduction in the normal case, when the contact surface is not in contact with the mating contact surface. The structural component can now ensure a transfer of force to the deformation component and vice versa through a corresponding assembly area. This force transfer assembly may for example be provided by welding, gluing, and bevelling, screwing or by a similar technical implementation of such an assembly feature. In the normal mode of the bodywork part, the force transfer is provided exclusively or essentially exclusively through this assembly between the structural component and the deformation component.
    An additional advantage in the case of a bodywork part according to the invention is that the contact surface has at least two contact surface portions which form or together constitute in particular or in particular an acute angle. Such contact surface portions therefore serve, in particular, to provide mutual clamping so that a corresponding increase in the transfer of force between the contact surface portions and the corresponding conjugate contact surface portions in the case is available. a strengthening of the collision force applied. The contact surface portions may in this case be prolonged in one another but also be made spaced apart from one another. As regards the normals on the surface of the two portions of the contact surface, a different orientation is preferably available, so that, for example, a first portion of contact surface is directed upwards and a second portion of surface of contact is facing down. If now, by the displacement by overcoming the normal spacing, the contact surface portions are brought into contact with the mating contact surface, this acute angle arrangement further generates a clamping effect with a force correspondingly increasing contact during deformation in the event of a collision.
    It is furthermore advantageous, in a bodywork part according to the invention, for the deformation component to have a lower or lower mechanical stability than that of the structural component, in particular with a direction or direction of deformation and / or a type of deformation. predefined deformation. This can in particular be ensured by the corresponding embodiment or selection of the materials of the deformation component. While the structural component is preferably made of steel, the deforming component may for example be a spun section or have such a profile. In particular, aluminum is used as the construction material for the deformation component in order to be able to guarantee this targeted energy reduction. In the case of lower collision situations, this preferably leads essentially only to deformation of the deformation component. Thus, the structural component can be protected and repair by replacing the deformation component can be kept economical and simple.
    It is furthermore advantageous, in the case of a bodywork part according to the invention, that the assembly component has a guiding surface which is applied with or by guiding against a conjugate guiding surface of the structural component to ensure guiding the contact surface in contact with the mating contact surface in the event of a collision. In this case, there is preferably no support of forces in normal mode or only a weak support. On the contrary, the guiding surface is applied against the conjugate guiding surface to also ensure that warpage of the assembly component is avoided during the collision. Preferably, the guide surface and the corresponding mating guide surface, in one embodiment, are oriented in the direction of a force exerted in a collision. As a result, in both normal and crash mode, the guide surface can not be affected by force transfer functionality.
    An additional advantage, in the case of a bodywork part according to the invention, is that the deformation component is in the form of a spun section, in particular having aluminum. Such a spun section gives rise to a particularly simple and economical manufacturing. In addition, a reduction in weight can be obtained economically and simply by the corresponding formation of profiles and in particular by the use of aluminum. The object of the present invention is also an assembly component for assembling a deforming component and a structural component for producing a bodywork part according to the present invention, having a contact surface for coming into contact with each other. or for bringing into contact with a mating contact surface of the structural component. Consequently, an assembly component according to the invention provides the same advantages as those expressly explained with reference to a bodywork part according to the invention. Other advantages and features of the invention result from the following description in which exemplary embodiments of the invention are described in detail with reference to the drawings. In this case, the features mentioned in the description may be essential to the invention individually or in any combination.
    The figures illustrate schematically: in FIG. 1, an embodiment of a bodywork part according to the invention, in FIG. 2, the embodiment of FIG. 1 according to a different view, in FIG. embodiment of FIGS. 1 and 2 with a closed structural component, in FIG. 4, a further embodiment of a bodywork part according to the invention and in FIG. 5, the embodiment of FIG. collision.
    Figures 1 and 2 illustrate an open bodywork part 10 with a structural component 20, to which is attached a deformation component 30 for the transfer of forces in normal operation. In the event of a collision, additional assembly functionality is provided by means of an assembly component 40. The assembly component 40 is assembled for this purpose with force transfer to the deformation component 30. The component deformation 30 is manufactured as a spun aluminum profile. If there is now a collision situation, this collision situation will be exerted with a force transfer to the deformation component 30 and consequently to the assembly component 40. By a corresponding short relative movement, a normal spacing NA is surmounted between corresponding contact surfaces 42 of the assembly component 40 and the mating contact surfaces 22 of the structural component 20. As soon as this contact is established, by the additional support, a discharge of the separate connection fasteners between the component 20 and the deformation component 30 is made.
    As further illustrated in FIGS. 1 and 2, there is provided a perpendicularly arranged guiding surface 46 which provides guiding functionality in application between the joining component 40 and a conjugate guiding surface 26 of the structural component 20.
    FIG. 3 illustrates the embodiment of FIGS. 1 and 2 with a corresponding possibility of closure of the structural component 20. In this case, an overlap between an end portion 32 of the deformation component 30 and the structural component 20. This leads to improved protection of the assembly component located inside 40, in particular against soiling or obstacles in the normal spacing NA.
    FIGS. 4 and 5 illustrate an additional embodiment of a bodywork part 10, the normal case being illustrated in FIG. 4, in which, between different contact surface portions 44 of the contact surface 40, there is a spacing corresponding to the associated mating contact surfaces 22. In FIG. 5 is illustrated the collision case in which this normal spacing NA has been overcome so that the additional contact between the surface is now available. 42 and the mating contact surface 22, a corresponding additional force transfer to protect a separate assembly between the structural component 20 and the deformation component 30.
