Technical Field

The present invention relates to a vehicle housing assembly having the features of the preamble of claim 1.

Background

Vehicle shell assemblies of this type are known in practice and in particular constitute panel elements which are arranged in the front or rear region of the vehicle. Known vehicle enclosure assemblies include a plate-like plastic body, the outer side of which forms the visible surface and the inner side of which faces the vehicle interior. The plate-shaped plastic body forms a closed surface which is opaque and has a black and shiny high-quality outer side. This plastic body thus constitutes a so-called "black panel appearance".

Disclosure of Invention

It is an object of the present invention to provide a vehicle housing assembly realized in accordance with the generic type mentioned in the introduction and having a variable optical appearance.

According to the invention, this object is achieved by a vehicle housing assembly having the features of claim 1.

According to the present invention, a vehicle housing assembly is provided that includes a plate-like plastic body having an interior side and an exterior side. A lighting unit configured to be switchable between an active state and an inactive state is arranged on the inside of the plastic body, i.e. on the side of the plastic body facing away from the outside. In the active state, the lighting unit is illuminated. In the inactive state, the lighting unit does not emit light. The inner side of the plastic body is provided with an opaque, light-tight coating, which has at least one gap. Furthermore, the plastic body is composed of a translucent material, such that the gap is covered by the plastic body from the outside when the lighting unit is in the inactive state, and the gap determines a light pattern visible from the outside or around the vehicle when the lighting unit is in the active state.

The vehicle housing assembly according to the invention is therefore characterized in that the material of the plastic body is selected to cover the coating with the at least one gap when the lighting unit is in the inactive state. This is done by selecting a suitable translucent or substantially tinted plastic material. However, in the activated state of the lighting unit, which emits light in a direction towards the opaque coating or the plate-like plastic body, a light pattern can be seen from the vehicle surroundings, which light pattern is defined by the opaque coating having at least one gap, which at least one gap passes the light of the lighting unit. The coating thus forms a mask on the inside of the plastic body and determines the light pattern by the shape and number of the gaps.

The vehicle housing assembly according to the invention may be integrated in various ways on the outside of the vehicle. For example, the vehicle housing component forms a panel element which forms a visible surface in the region of a front or rear bumper of the vehicle. The vehicle housing assembly according to the invention can also be arranged between two ribs embodied in the bumper region. In this case, the plate-shaped plastic body may be made integral with the ribs. However, it is also conceivable for the vehicle housing assembly according to the invention to be integrated in the region of the rear spoiler or in the region of the trunk lid alongside the lighting unit of the vehicle concerned.

The term "plate-like" is to be understood in its broadest sense, i.e. the plastic body may be a flat, planar or curved element with smooth or structured outer sides. It is also conceivable that the plate-shaped plastic body is incorporated into a rib or other vehicle structure, filling the space between the ribs or other vehicle structures.

In order to promote a three-dimensional light effect or depth effect of the light effect, the inner side of the plastic body has recesses in the gap regions of the coating.

The recesses have boundary surfaces which are preferably inclined with respect to one another. This means that an angle is achieved between the boundary surfaces, which angle makes it possible in particular to determine sharp-edged structures. In this case, the boundary surfaces are separated from each other by sharp dividing lines. For example, the concave portion has a pyramid shape or the like.

When the lighting unit is in the activated state, the reduced material thickness of the plastic body in the region of the recess leads to a depth effect with a light intensity that varies, in particular over the surface, preferably within a sharp-edged pattern. When the lighting unit is switched off, i.e. in the inactive state, no sharp-edged pattern is visible.

In one exemplary embodiment, the plastic body may have a base material thickness of about 4mm to 6 mm. In the region of the recess, the plastic body can have a reduced material thickness of, for example, approximately 1.0mm to 3.5 mm. Of course, smaller material thicknesses are also conceivable.

In a particular embodiment of the vehicle housing component according to the invention, the coating is formed by a film, a varnish coating or a printed graphic.

As an alternative, it is conceivable that the plastic body and the coating form a two-component injection-molded part, and that the plastic body is formed by the translucent first material component of the two-component injection-molded part and that the coating is formed by the opaque second material component of the two-component injection-molded part.

The coating may be of substantially any color. It is only necessary to ensure that the coating does not let any light emitted by the lighting unit pass. However, in particular, the coating may be black, which promotes a so-called "black panel appearance".

In a special embodiment of the vehicle housing assembly according to the invention, the plastic body consisting of a translucent material is made of a polycarbonate material. The polycarbonate material has in particular an outer side formed by a high-quality, highly polished surface. Coloring the polycarbonate material black and applying a black coating produces a piano black appearance.

In an alternative embodiment of the vehicle housing assembly according to the invention, the plastic body is made of a polyurethane material having translucent properties.

In order to make the vehicle housing assembly according to the invention wear-resistant, it is advantageous to provide a scratch-resistant coating on the outside of the plastic body. The scratch-resistant coating may consist of a varnish coating or a protective film.

The plate-shaped plastic body provided with the opaque coating is preferably backlit in a uniform manner over the entire surface of the plastic body. To achieve this, a lighting unit is provided which may comprise LED light sources or another light source, and a diffusing layer to distribute the light emitted by the light sources evenly over the surface of the lighting unit.

In order to prevent light from escaping from the side, the lighting unit may have a housing which abuts the opaque coating in a light-tight manner. This ensures that the light emitted by the light source of the illumination unit is emitted only in the direction of the opaque coating or only in the direction of the plate-shaped plastic body.

In an advantageous embodiment of the vehicle housing assembly according to the invention, the luminous intensity and/or the luminous color of the lighting unit is adjustable. In this way, specific customer requirements can be met and effects, such as popular effects, can be built.

Further advantages and advantageous embodiments of the inventive subject matter are apparent from the description, the drawings and the claims.

FIG. 2 shows a top view of the vehicle housing assembly in an inactive state of a lighting unit of the vehicle housing assembly;

FIG. 3 shows a top view of the vehicle housing assembly in an activated state of the lighting unit; and

Detailed Description

The figures show a motor vehicle 10 embodied as a passenger vehicle and having a bumper assembly 12 extending in a transverse direction of the vehicle at a front portion of the vehicle. The bumper assembly 12 is disposed below the radiator grill 14.

The bumper assembly 12 is embodied in its end region as a vehicle housing assembly 16, which vehicle housing assembly 16 is arranged on each side of a vehicle vertical longitudinal center plane, which vehicle housing assembly 16 provides an additional design element of the motor vehicle 10 and may be illuminated as desired.

As shown in fig. 2 and 3, the vehicle housing assembly 16 includes a plate-like plastic body 18 made of a translucent black polycarbonate material. The plastic body 18 is provided with a scratch-resistant lacquer 20 on the outside.

On the inner side facing away from the scratch-resistant coating 20, the plastic body 18 is provided with a coating 22, which coating 22 consists of a black polycarbonate film and is embodied in an opaque or light-tight manner. The coating 22 has a plurality of gaps 24, each gap 24 having a rectangular profile in the present application. The coating 22 thus forms a mask of the plastic body 18 on the inside.

The inner side of the plate-shaped plastic body 18 has a pyramid-shaped recess 26 in the region of each gap 24, so that the material thickness of the plastic body 18 in the region of the gap 24 is reduced in comparison with the base material thickness. The pyramid surfaces of the recesses 26 are each separated from each other by a sharp dividing line, i.e. by a pyramid edge formed by the surfaces. For example, the plastic body 18 has a base material thickness of 5mm, while the material thickness decreases in the region of the gap 24 or the apex of the recess 26 to approximately 3.5 mm.

Furthermore, the vehicle housing components 16 each have a lighting unit 28, with which lighting unit 28 the unit consisting of the plastic body 18 and the coating 22 can be backlit over its entire surface. The lighting unit 28 comprises a housing 30, which housing 30 bears with its edges against the coating 22 so as not to let any light pass and receives a light source 32 formed by at least one LED. Furthermore, a diffusion layer 34 is arranged between the light sources 32 and the coating 22, said diffusion layer 34 producing a light output which is uniformly present over the surface of the lighting unit 28 when the light sources 32 are activated.

The plastic material of the plastic body 18 is dyed such that the vehicle enclosure assembly appears completely black and uniform from the outside when the light source 32 is not activated. The pattern presented by the coating 22 and the gaps 24 and recesses 26 embodied therein cannot be seen (fig. 2). However, if the light source 32 is switched to the active state, emitting light in a direction towards the coating 22, light is irradiated through the gap 24, so that light is irradiated through the plastic body 18 via the recess 26, and the light pattern shown in fig. 3, which is defined by the shape of the gap 24 and the shape of the recess 26, can be seen from around the vehicle.
