Description

[0001] The invention relates to an electric vehicle with a vehicle front and a license plate holder arrangement arranged on the vehicle front.

[0002] EP 2 141 049 A1 discloses a mounting device for a license plate, comprising a frame, a mounting surface for securing and backlighting a plate, and a lighting device on the frame for illuminating the plate from above. This enables the license plate to be illuminated using multiple lighting devices that require electrical power.

[0003] WO 2010 / 103430 A1 discloses a vehicle with a front end and a license plate holder assembly arranged on the front end. A daytime running light is provided on each side of the license plate, which is pivotably mounted on the license plate holder assembly by means of a joint.

[0004] JP 2005 - 145 266 A discloses another vehicle in which a daytime running light is arranged on each side of the license plate holder arrangement.

[0005] US 2005 / 0 094 405 A1 relates to a lighting device for illuminating a license plate of a vehicle.

[0006] US 2012 / 0 281 426 A1 discloses a system for mounting additional headlights on vehicles.

[0007] US 2014 / 0 253 278 A1 relates to a secondary transformer unit for attachment to an electric vehicle.

[0008] The object of the invention is to provide an improved electric vehicle.

[0009] This object is achieved by the electric vehicle according to claim 1.

[0010] The electric vehicle, with a vehicle front and a license plate holder assembly arranged at the vehicle front, has a license plate holder for a license plate and a daytime running light. The license plate holder has a receiving area for the license plate, which is delimited by at least one mounting surface (which is oriented toward the front of the vehicle or borders the rear of a mounted license plate). The daytime running light is configured and / or arranged such that, when switched on, it emits light along a main radiation direction. The main radiation direction is oriented along or parallel to a normal vector of the mounting surface (and is thus oriented along or parallel to the vehicle's longitudinal direction when the license plate holder assembly is mounted on the electric vehicle).The daytime running light is designed as a light bar arranged above or below the mounting area of ​​the license plate holder, or as an LED light unit arranged on or in the license plate holder. This allows for compact and structurally advantageous placement of a daytime running light on or in the license plate holder. The light bar is coupled to the license plate holder by means of a guide, allowing the light bar to be displaced relative to the license plate holder along or parallel to the normal vector of the mounting surface. Thus, the daytime running light is mounted in a guide that can compensate for deformation paths in the direction of the normal vector (when mounted, along or parallel to the vehicle's longitudinal direction or X-direction).

[0011] The LED lighting unit can comprise one or more LEDs as the light source, which are arranged adjacent to one another in such a way that they form an illuminated area, for example, a rectangular or square one. The light bar can also comprise one or more LEDs as the light source, which can be arranged adjacent to one another along the length of the light bar.

[0012] The daytime running light, in particular the LED light unit and / or the light bar can have a lateral beam angle (beam angle to the sides of the license plate holder or beam angle in the transverse direction of the vehicle) of ± 20° around the main beam direction and / or a vertical beam angle (beam angle upwards and downwards of the license plate holder or beam angle in the transverse direction of the vehicle) of ± 10° around the main beam direction.

[0013] The electric vehicle can be a partially electric or fully electric (purely battery-electric) vehicle, particularly in the form of a car or SUV.

[0014] Preferably, the LED light unit can be arranged within the clear cross-section of the receiving area for the license plate. This contributes to a compact and stable design. Thus, the LED light unit can be arranged within a lateral boundary of the receiving area—as viewed along the normal direction of the mounting surface—for example, within a frame that laterally delimits the receiving area. In particular, the LED light unit can be arranged on the right-hand edge of the receiving area for the license plate, as viewed from above, for example, where the letter "E" is located on the license plate of an electric vehicle.

[0015] Preferably, the LED light unit can be designed to represent an illuminated letter "E" or to be configured as a luminous surface (e.g., an illuminated rectangle) on which a non-luminous letter "E" is applied. This identifies the vehicle as an electric vehicle and simultaneously fulfills the function of a daytime running light.

[0016] Preferably, the LED light unit can be connected to the license plate holder or to a license plate located in the receiving area of ​​the license plate holder. Depending on the design, the LED light unit can form a component of the license plate holder or the license plate.

[0017] Preferably, the light bar can extend at least half the width of the license plate holder or across the entire width of the license plate holder. This allows for a comparatively large illuminated area. This enhances the visibility of the vehicle equipped with daytime running lights, for example, by oncoming traffic.

[0018] Preferably, the light bar can be configured and / or arranged such that, when switched on, it emits or transmits light along a secondary emission direction, wherein the secondary emission direction is directed toward the receiving area for the license plate or intersects the receiving area. This not only realizes the function of a daytime running light in an energy-efficient manner, but also illuminates the receiving area or the license plate arranged in the receiving area (reflection effect on the license plate) with a single light source.

[0019] The license plate holder can preferably have a frame that delimits the receiving area for the vehicle license plate laterally (to the top, bottom, and / or the two other sides, i.e., to the right and left), with a receptacle for the light bar being formed in a section of the frame arranged above or below the receiving area. This contributes to a compact and protected arrangement of the light bar in the license plate holder. The receptacle is open in the main radiation direction (oriented along or parallel to the vehicle's longitudinal direction when mounted), so that the light bar can emit light along the main radiation direction.

[0020] Preferably, an opening can be formed in the license plate carrier that connects the receptacle for the light bar and the receiving area for the license plate. This provides a path for the light bar, which can be arranged, for example, in a receptacle (see above), so that the light bar can radiate along the secondary radiation direction onto the receiving area or a license plate arranged there. This promotes a compact and stable design.

[0021] The electric vehicle has the vehicle front and the license plate holder arrangement arranged on the vehicle front, in particular also fastened there.

[0022] For the advantages, please refer to the relevant comments on the license plate holder arrangement. The measures described above regarding the license plate holder arrangement and / or those explained below can be used to further configure the electric vehicle.

[0023] Further advantageous embodiments will become apparent from the following description and the drawing. The drawing shows, schematically, Fig. 1 a plan view of the license plate holder assembly; Fig. 2 a plan view of a possible design of the license plate holder arrangement; and Fig. 3a,b a further design option for the license plate holder arrangement in a perspective view ( Fig. 3a) and a partially sectioned side view ( Fig. 3b).

[0024] In Fig. 1 shows a schematic plan view of the license plate holder assembly 10. In addition, Fig. 1 shows an electric vehicle 100 with a vehicle front 102, to which the license plate holder assembly 10 is arranged and fastened, for example, by screwing or by means of plug connections. The license plate holder assembly 10 is described below.

[0025] The license plate holder assembly 10 is configured and / or intended for the front end 102 of the electric vehicle 100. The license plate holder assembly 10 includes a license plate holder 12 for a vehicle license plate 14 and a daytime running light 16. The license plate holder 12 includes a receiving area 18 for the vehicle license plate 14, which is delimited by at least one mounting surface 20 toward the front end 102 (rear side of the vehicle license plate 14).

[0026] When switched on, the daytime running light 16 emits light along a main emission direction 22, wherein the main emission direction 22 is oriented along or parallel to a normal vector of the mounting surface 20 (not shown). Fig. 1, the main radiation direction 22 and the vehicle longitudinal direction protrude vertically from the plane of the drawing.

[0027] In the example, the daytime running light 16 is designed as a light bar 24 arranged below the receiving area 18 of the license plate holder 12. In the example, the light bar 24 extends across the entire width of the license plate holder 12. The light bar 24 can have one or more LEDs as the illuminating means, which can be arranged adjacent to one another along the longitudinal extent of the light bar 24.

[0028] Fig. 2 shows a possible design of the license plate holder arrangement 10, whereby, to avoid repetition, reference is first made to the above explanations.

[0029] In contrast, in the present license plate holder assembly 10, the daytime running light 16 is configured as an LED light unit 26 arranged on or in the license plate carrier 12. The LED light unit 26 is arranged within the clear cross-section of the receiving area 18. The LED light unit 26 can be arranged within a lateral boundary of the receiving area 18, as explained above.

[0030] In the example, the LED light unit 26 is designed as a luminous surface on which a letter "E" is applied, which is non-luminous in the example. Alternatively, the LED light unit 26 can be designed to represent a luminous letter "E" (not shown). Fig. 2, the main radiation direction 22 protrudes vertically from the plane of the drawing.

[0031] The LED light unit 26 can be connected to the license plate carrier 12 or to a license plate 14 arranged in the receiving area 18 of the license plate carrier 12, as described above.

[0032] The Fig. 3a and Fig. 3b show a further possible design of the license plate holder arrangement 10. To avoid repetition, reference is made to the above explanations. Fig. 1.

[0033] Deviating from this, the daytime running light 16, which is also designed as a light bar 24, is arranged in the example above the receiving area 18 of the license plate holder 12.

[0034] In the example, the light bar 24 extends across the entire width of the license plate holder 12. When switched on, the light bar 24 emits light not only along the main beam direction 22, but also along a secondary beam direction 30, wherein the secondary beam direction 30 is aligned with or intersects the receiving area 18 of the license plate holder 12. The main beam angle is designated by reference numeral 23, and the secondary beam angle is designated by reference numeral 31.

[0035] In the example, the license plate holder 12 has a merely indicated frame 32 that laterally delimits the receiving area 18 for the vehicle license plate 14, i.e., upwards, downwards, to the right, and to the left. A receptacle for the light bar 24 is formed in a section 34 of the frame 32 arranged above the receiving area 18 (not shown in detail).

[0036] An opening (also not shown in detail) is formed in the license plate carrier 12, which connects the receptacle for the light bar 24 to the receiving area 18 for the license plate 14. Through this opening, the light bar can emit light along the secondary emission direction 30 onto the receiving area 18.

[0037] The light bar 24 can be coupled to the license plate carrier 12 by means of a guide (not shown), whereby the light bar 24 can be displaced along or parallel to the normal vector or along the main radiation direction 22 relative to the license plate carrier 12.
