Description

DRAWING

(1) The drawing described herein is for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.

(2) FIG. 1 shows an embodiment in a sectional view in the second state, in which the light function is enabled and activated.

DESCRIPTION OF THE INVENTION

(3) A cladding part 40 according to the present disclosure is described below with the aid of a front panel as external cladding in the front region of an electric vehicle. It is clear that cladding part 40 may also be used as a cladding element at any other desired place on a motor vehicle. The cladding part 40 is preferably also a bumper cladding, a boot lid cladding, a door cladding, a roof cladding or a spoiler, or is a component of one of the aforementioned parts.

(4) The cladding part 40 has a base body 2 which is a three-dimensionally configured composite plastic component that may be manufactured by various production methods or method steps. In the drawing, the cladding part 40 is shown as a detail in a schematic sectional representation and has a front side (V) and a rear side (R). The front side V is the visible side of the body shell of the motor vehicle in the intended installation situation on the motor vehicle and is visible to a user.

(5) The composite plastic component comprises a deep-drawn three-dimensionally configured decoration carrier 4 and at least one externally-arranged transparent cover layer 5. The decoration carrier 4 is a plastic film, in particular a transparent plastic film, which has a colored coating/painting on the side facing toward the outer side. The painting may correspond in terms of coloration to the painting of the motor vehicle.

(6) The film as a decoration carrier 4 is back-injection-moulded by an injection-moulding method with a transparent polymer material, preferably a polycarbonate, on the side facing towards the front side in order to produce the cover layer 5.

(7) FIG. 1 shows an embodiment of the cladding part 40 according to the present disclosure with the base body 2 configured with a coloring coating. The base body 2 is produced from a plastic material such as a PP, polycarbonate or ABS and is painted in color. The base body 2 has a multiplicity of openings or recesses, which form light windows 49. The light windows 49 are configured conically with an internally running chamfer.

(8) As may be seen from the drawing, the device 47 is configured in the form of slide elements, also referred to below as inserts. The slide elements are mounted longitudinally displaceably in the light windows 49 and have a head region 47a with a visible side S5 directed toward the outer side and a conical section 46 formed on the rear side thereof. This conical section 46 is conical, or circumferentially chamfered, in its geometry so as to correspond to the chamfered or conically configured openings of the base body 2, and thus allows flush reception of the head region 47a in the light windows in the first position.

(9) Following on from the conical section 46, the inserts are configured with a pin guided through the opening. By means of this pin, the multiplicity of inserts are connected on the rear side to a holding element which, for adjustment into the second position which is represented in FIG. 1, comprises kinematics and actuators assigned to the holding element.

(10) The inserts may be configured as decoration elements, at least in the head region 47a, and may be configured with different colors, or as a chromed or PVD-coated component, at least on the visible side, side S5, directed toward the outer side.

(11) In one embodiment, the slide elements or inserts are painted at least on the visible side S5 uniformly like the painted base carrier 2, or the decoration carrier 4. This colour corresponds to the body colour, so that a uniform appearance which is as seamless as possible is formed for a user starting from the outer side in the first position, in which the device is inserted flush in the base body.

(12) In the second position represented in FIG. 1, the device 47 or the multiplicity of slide elements are displaced outwards beyond the surface contour of the base body 2 by means of an adjustment movement. In this position, there is respectively a circumferential light gap 49a between the openings in the base body 2 and the slide elements, so that the illumination function 48 is enabled and the emitted light can shine through the light gap toward the outer side.

(13) The illumination function 48 which can be enabled in the second state is in this case formed by the base body 2, which is configured as a light-guide body 53 at least in a rear sub-region. A light source 52 arranged at the rear in the internal space couples the light into the light-guide body. The light-guide body also comprises the chamfered section in the base body, which forms the circumferential contour of the light window. The light is then emitted by the circumferential contour as a light exit face 49 through the light gap 49a toward the outer side.

(14) The transparent light exit face in the base body is produced by masking, or by ablation (mechanical, lasering, etc.) of the coloring coating.

(15) In one embodiment, which is not represented, the light element itself is configured so that it is held embedded in the base body in the region of the opening and thus constitutes the circumferential contour of the opening.

(16) It is a feature of the chamfered, conically extending surfaces which delimit the light windows in the base body and the correspondingly configured supporting faces on the slide element that, during the adjustment movement in the first position with respect to one another, they form a defined end point for the retraction of the slide elements into the closed state, in order to generate a seamless appearance which is as flat as possible on the outer face of the cladding element. Furthermore, in this first position the illumination function itself is concealed and is not visible in the closed state.

(17) The shape of the openings and of the slide elements may be selected freely, so that besides angled and round shapes even more complex contours such as brand emblems and lettering may be represented here.
