Description

The invention relates to a support part with a tubular body which has at least one fastening end. The invention further relates to a motor vehicle with a rear panel which is fastened with a screw at a screwing point on a first end of such a support part.

From the American Offenlegungsschrift US 2007/0271793 A1 A hybrid component is known which comprises a steel component and a cast coupling element which is cast onto a part of the steel element by casting a semi-solid aluminum body around the part of the steel element, whereby the coupling element is positively and rigidly attached to the steel element, the steel component is a tubular component. From the European patent specification EP 2 048 407 B1 discloses an absorption unit for kinetic energy for a motor vehicle having an absorption tube in which at least one outer layer is made of plastic and with a groove holder made of metal. From the German Offenlegungsschrift DE 41 27 597 A1 a deformation element for a motor vehicle is known, with a hollow beam deformable when longitudinal force is applied by buckling folds and a support surface opposite one end thereof, which is concave and to which the end of the hollow beam is attached.

The object of the invention is to improve a support part with a tubular body which has at least one fastening end with regard to its operational strength in an assembled state.

In the case of a support part with a tubular body which has at least one fastening end, the object is achieved in that a sheet metal nut is mounted on the fastening end with the aid of a plug connection in order to represent a screwing point on the fastening end. The assembly of the sheet metal nut is considerably simplified by the plug connection. In addition, the assembled sheet metal nut is held by the plug connection in the assembled state on the fastening end of the tubular body. This considerably simplifies the fastening of a motor vehicle component, for example a rear panel, with a screw to the fastening end of the tubular body with the sheet metal nut.

A preferred exemplary embodiment of the support part is characterized in that the sheet metal nut has at least one spring leg which is inserted into the fastening end of the tubular body. The spring leg can advantageously be adapted to the shape of a receiving space in the fastening end of the tubular body. Depending on the design of the sheet metal nut, it can also have two spring legs, by means of which a form-fitting reception in the fastening end of the tubular body is made possible.

Another preferred exemplary embodiment of the support part is characterized in that the tubular body is pressed together at the fastening end in such a way that a receiving slot is produced which is used to represent the plug connection at the fastening end. The sheet metal nut is simply inserted into the receiving slot with the at least one spring leg during assembly. By means of two spring legs which are spaced apart from one another and extend parallel to one another, a particularly stable receptacle can be implemented in the receiving slot in a simple manner.

Another preferred embodiment of the support part is characterized in that the sheet metal nut is designed as a C-clip sheet metal nut. The support part is particularly advantageously designed at the fastening end in such a way that a conventional sheet metal nut with the claimed plug connection can be mounted on the support part in a stable manner in a simple manner.

Another preferred embodiment of the support part is characterized in that the fastening end is angled from the tubular body. In the assembled state, the tubular body preferably extends in a vehicle height direction, which is also referred to as the z-direction. In the vehicle height direction, the fastening end with the sheet metal nut is preferably arranged at the bottom. This enables a vehicle component, such as a rear panel, to be fastened from below to the fastening end of the support part with the sheet metal nut.

Another preferred embodiment of the support part is characterized in that the tubular body has a through hole at the fastening end, which is arranged coaxially with a through hole in the sheet metal nut. The sheet metal nut is advantageously connected in one piece with a threaded sleeve. As a result, a particularly stable screwing point is realized on the fastening end of the support part.

Another preferred embodiment of the support part is characterized in that the tubular body has a second compressed fastening end with a through hole. This enables the support part to be fastened to a support structure of a motor vehicle, for example to a bumper beam, with a screw in a simple manner.

The invention also relates to a motor vehicle with a rear panel that is equipped with a Screw is attached to a screwing point on a first end of a support part described above. The support part is preferably formed from a lightweight aluminum material that is relatively easy to deform. This simplifies the pressing together of the tubular body at the at least one fastening end, preferably at both fastening ends. The sheet metal nut is preferably formed from a sheet steel material.

A preferred exemplary embodiment of the method is characterized in that the support part is fastened with a second end to a bumper beam of the motor vehicle. The two attachment points at which the ends of the support part are attached to the rear panel and to the bumper beam of the motor vehicle are advantageously arranged vertically one above the other in a z-direction or vehicle height direction. Thus, the support part can advantageously be used as a tension / compression rod in an excitation direction orthogonal to a roadway and does not experience any introduction of moments.

The invention also relates to a tubular body and / or a sheet metal nut for a support part described above. The pipe body and the sheet metal nut can be traded separately.
