Body part of a vehicle

Abstract

A body part (10) of a vehicle includes a structural component (20) and a deformation component (30). A connecting component (40) is fastened to an end portion of the deformation component (30). The connecting component (40) has a contact surface (42) configured to come into contact with a mating contact surface (22) of the structural component. A normal spacing is formed between the contact surface (42) and the mating contact surface (22), and the connecting component (40) is configured to form force-transmitting contact between the contact surface (42) and the mating contact surface (22) in the event of a crash.

Description

technical field

[0001] The invention relates to a body part of a vehicle and to a connection element for use in such a body part. Background technique

[0002] It is known that vehicles have individual body parts forming the vehicle body. Such body parts are often formed in multiple parts and have, in particular, structural parts. It is also known that, together with these structural parts, special deformations are also provided which absorb and dissipate energy by their deformation in the event of a crash and in this way represent a passive Protective function.

[0003] A problem with known body parts is that the connection between the structural part and the deformation part is relatively complex. In particular, such a connection would even have to withstand impacts in order to be able to dissipate corresponding energy initially by deformation of the deformation parts. For this purpose, a high degree of complexity is often required in order to ensure that the deformati...

Examples

Embodiment Construction

[0029] figure 1 and figure 2 An open body part 10 is shown having a structural part 20 to which a deformation part 30 for transmitting forces in normal operation is fastened. For crash situations, an additional connection function is provided by means of the connection piece 40 . To this end, the connection piece 40 is connected to the deformation piece 30 in a force-transmitting manner. The deformation part 30 is produced as an extrusion made of aluminum.

[0030] If a crash situation occurs, this crash situation will cause a force to be transmitted to the deformation part 30 and thus to the connection part 40 . As a result of the correspondingly shorter relative movement, the normal spacing NA between the contact surface 42 of the respective connection part 40 and the mating contact surface 22 of the structural part 20 is overcome. Once this contact has occurred, the individual attachment fasteners between the structural member 20 and the deformable member 30 are reliev...
