Description

The invention relates to a design component for a vehicle. Furthermore, the invention relates to a corresponding method for producing such a design component.Design components for vehicles and corresponding methods for producing such a design component are known in numerous variations. Design components, such as a backlit front panel for a vehicle front, with an inserted and printed film, are known from the prior art, which are produced in a 3K injection molding process (3K: three components). In this case, the inserted film is initially back-injected over its entire surface with a transparent polycarbonate as the first component. Subsequently, a circumferential frame with fastening elements is injection-molded as a second component. As a third component, the visible side of the printed film is flooded with a polyurethane, so that the component is protected on the visible side.It can be considered disadvantageous in this case that for such large design components correspondingly large injection molding machines are required, which have to be produced as special production, and tools are required, which are very expensive.DE 10 2017 205 202 A1 discloses a polyurethane-based display which comprises a decorative element having at least one cutout. At least one printed film is arranged in the cutout in such a way that the printed part is visible. The printed film is coated with a first polyurethane layer.WO 2010 / 091898 A1 discloses a two-component (2K) polyurethane paint for a carrier film and a method for the production thereof and the use thereof for finishing molded plastic parts.The invention is based on the object of providing a design component for a vehicle and a corresponding method for producing such a design component, which can be produced cost-effectively.This object is achieved by a design component for a vehicle having the features of claim 1 and by a method for producing such a design component having the features of claim 7. Advantageous embodiments with expedient developments of the invention are specified in the dependent patent claims.In order to provide a design component for a vehicle which can be produced cost-effectively, the design component comprises a carrier housing which has a circumferential connecting channel, and a film which is geometrically adapted thereto and flooded with a polyurethane layer or with a polyurea layer and which is bonded at its angled edge region into the connecting channel and is connected to the carrier housing.In addition, a method for producing such a design component with the following steps is proposed. providing a film having an angled edge region. flooding a visible side of the film with a polyurethane layer or with a polyurea layer and connecting the angled edge of the flooded film to a rear carrier housing. In this case, the angled edge region of the flooded film is adhesively bonded in a circumferentially extending connecting channel of the carrier housing.The film is understood below as meaning a pretreated, preferably a printed film. In this case, the film can be hot stamped and / or have a PVD coating. It is also possible to apply graphic objects to the surface of at least one of the two sides of the film by other suitable methods. The film may preferably have a thickness in the range between 0.5 and 4 millimeters.Embodiments of the design component for a vehicle according to the invention can preferably be designed as a front panel for a vehicle front, and can advantageously be produced using more cost-effective tools and a shorter production process in a 1K injection molding process (1K: a component. As a result, the design components according to the invention can be produced more cost-effectively with the same appearance and performance. In this case, the film is no longer back-injected over its entire surface with a polycarbonate or over the edge region with a frame made of a polycarbonate plastic (PC) or of an acrylonitrile-butadiene-styrene copolymer plastic (ABS) or of a mixture of the two plastics, but the preformed film is placed in the injection mold and flooded with a polyurethane (PUR) or with a polyurea (PUA) in a one-component injection molding process.In an advantageous embodiment of the design component, a sealing edge with a demolding bevel can be formed on the angled edge region of the film. In this case, the demolding slope of the sealing edge can have an inclination in the range from 3 to 12 degrees. This makes it possible to prevent the polyurethane from flowing into the cavity of the injection mold.In a further advantageous embodiment of the design component, at least one support element can be arranged on the carrier housing, which support element supports the flooded film on its rear side. This can increase the stability of the flooded film.In a further advantageous embodiment of the design component, at least one lighting means for backlighting the flooded film can be arranged in the carrier housing. As a result, various optical effects can be generated and implemented.In an advantageous embodiment of the method, the angled edge region of the film can form a sealing edge with a demolding bevel.The features and combinations of features mentioned above in the description and the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figures can be used not only in the respectively specified combination but also in other combinations or alone without departing from the scope of the invention. Therefore, embodiments are also to be considered included and disclosed by the invention, which are not explicitly shown or explained in the figures, but which emerge from the explained embodiments and can be generated by separate combinations of features.Exemplary embodiments of the invention are illustrated in the drawings and are explained in more detail in the following description. In the drawings, like reference numerals designate components or elements that perform like or analogous functions. The following are shown here: FIG. 1 shows a schematic and sectional illustration of a vehicle with an exemplary embodiment of a design component according to the invention; FIG. 2 shows a schematic sectional illustration of a flooded film of the design component according to the invention for a vehicle; FIG. 3 is a schematic sectional view taken along the line III--III in FIG. 1; and FIG. 4 shows a schematic flow diagram of an exemplary embodiment of a method according to the invention for producing a design component from FIGS. 1 to 3.As can be seen from FIGS. 1 to 3, the illustrated exemplary embodiment of a design component 10 according to the invention for a vehicle 1 comprises a carrier housing 16 which has a circumferential connecting channel 18, and a film 12 which is geometrically adapted thereto and flooded with a polyurethane layer 14 (PUR) or with a polyurea layer (PUA), which is bonded at its angled edge region into the connecting channel 18 and is connected to the carrier housing 16.In the exemplary embodiment shown, the design component 10 is designed as a backlit front panel for a front 3 of the vehicle 1. As can be further seen from FIGS. 2 and 3, a sealing edge 12.1 with a demolding bevel is formed on the angled edge region of the film 12. the demolding bevel of the sealing edge 12.1 has an inclination in the range from 3 to 12 degrees and prevents the polyurethane from entering a cavity of the injection mold. In addition, in the exemplary embodiment shown, the film 12 is printed on the surface of at least one of its two sides and flooded with a polyurethane layer 16 (PUR).As can be further seen from FIG. 3, two support elements 16.1, which are designed as separating walls and support the flooded film 12 on the rear side thereof, are arranged on the carrier housing 16. In the illustrated exemplary embodiment of the design component 10, three lighting means 19 for backlighting the flooded printed film 12 are arranged in the carrier housing 16. Here, the lighting means 19 are separated from one another by the supporting elements 16.1, which are designed as separating walls. In the exemplary embodiment shown, the printed film 12 has a thickness in the range between 0.5 and 4 millimeters.As can be further seen from FIG. 4, the illustrated exemplary embodiment of a method 100 according to the invention for producing a design component 10 comprises a step S 100, in which a film 12 having an angled edge region is provided.
