Rear panel for motor vehicles

The innovation concerns a rear panel for motor vehicles, which can be installed on the body between the two rear lights designed as multi-chamber lights, consisting of a transparent colored outer shell, which is made from a structure-free plate using a deep-drawing process and of an opaque, reflective rear cover applied to the back of the outer shell and with a structure corresponding to the optics of the lens of the rear lights.

In a known, commercially available rear panel of this type, the rear cover consists of a flat plate into which the structure is introduced by rolling. Since the bottom surface of the outer shell is stepped, the rear cover is made of several parts. This multi-part design of the cover not only requires several work steps to connect it to the outer shell, but it also does not give the outer shell any additional rigidity. In addition, the rear cover is only provided with a uniform structure for the entire rear panel, so that, for example, no imitation of the optics for the lights and additionally for the optics of the reflector was made. Such a separation of the rear cover could only be made with the known rear panel if the outer shell also has a step in the separation plane between the reflector and the adjacent light chambers. This is necessary because the rear cover of the shell must be airtight or at least watertight, otherwise water will collect between the outer shell and the rear cover. At the very least, precautions must be taken to ensure that the connecting seam between the two plates is not visible in this area.

The aim of the innovation is to improve a rear panel of the type mentioned above in such a way that it can have a different structure in individual sections and has a high torsional rigidity despite the relatively thin outer shell. This task is solved according to the innovation by applying the following features:

ä) the rear cover of the outer shell is designed as an inner shell, the

b) follows the surface contour of the outer shell at a small distance and at least on the largest surface area approximately equidistantly/

c) the inner shell is produced using the deep-drawing process/

d) the structure is incorporated into the inner shell during the deep-drawing process /

e) the outer shell and the inner shell are connected to each other at their peripheral edges.

In an advantageous embodiment of the innovation, the structure of the areas of the inner shell adjacent to the rear lights, which run vertically and perpendicular to the direction of travel in the installation position, corresponds to the respective optical elements of the adjacent lens sections of the rear light. This gives the impression, when the lights are switched off, that the brake light and the reflector, for example, extend far into the rear panel.

In order to achieve a high brilliance corresponding to the lens of the rear lights, according to another feature of the innovation, the inner shell is glossy, preferably painted silver, or vapor-deposited.

If the inner parts of the rear light are red/ then the outer shell of the rear panel is made of red material/ if it is yellow/ then yellow material is used* If the rear light has both a red and a yellow color on the inside/ then yellow material is used/ which is painted red in the areas/ that are at the height of the red part of the rear light. If the colorless window for the reversing light is in the

Inner width 1 c &pgr; of the rear lights/ so If the outer shell is made of

■*■" Made of fair-faced material and partially painted yellow and red.

To prevent condensation from accumulating between the inner and outer shells, these two shells are welded together in an airtight manner. It is advantageous if the through holes for attaching the license plate in the outer shell are surrounded by an inwardly projecting collar, the front surface of which is welded to the inner shell.

In a further advantageous embodiment of the innovation, the inner and outer shells are placed one on top of the other with their outer edges pointing in the opposite direction and are welded with their edges lying close together. This

Design not only provides high tightness

between the two shells, but also gives the panel a high connection rigidity.

It is advantageous to provide the surface areas running in the direction of travel with a structure when pulling the inner shell. This structure advantageously corresponds to the structure of the side wall parts of the lens of the rear lights.

Figure 2 opens Sohniti along the line AA.

The 4; rear panel consists of the outer shell (1) and the inner shell (2). The outer shell (13) is deep-drawn from a transparent plate material. The plate material either already has the desired signal color, namely red or yellow, or it is colorless and is painted in the desired signal colors.

The inner shell (2) is deep-drawn from an opaque sheet material and has at least approximately the same shape as the outer shell. The inner shell has a structure on its inner surface which is different in individual surface areas and corresponds in shape to the optical elements of the light disc sections assigned to the individual lamp chambers. This applies both to the scattering lenses of the light disc sections in front of the light bulbs and to the retro-reflecting triplets. For example, section 3 of the inside of the inner shell (2) has the structure of a honeycomb-shaped lens optic, while section 4 imitates retro-reflecting triplets.

The abutting surfaces (5) of a step and the frame-shaped edges (6) of the cover have the structure of the outer edges of the light. This structure is usually a ribbing running in the direction of travel.

This different structuring of the inner surface of the inner shell is introduced during the deep-drawing process, but at least before the deep-drawn inner shell cools down.

The inner and outer shells are stacked one inside the other so that their outer edges (7, 8) point in the same direction. Their edges (7, 8) lie close together so that the two shells (1, 2) can be easily welded together.

In the middle area, the rear panel has a recess, on whose base (9) the license plate is placed. To attach the license plate, the rear panel has a through hole (10) for a screw bolt in this base (9). The through holes (10) in the outer shell (1) are surrounded by a collar (11) that projects towards the inner shell (2) and rests with its front side on the inner shell (2). The inner shell and the outer shell are welded together in these contact surfaces.
