Description

Hereinafter, a vehicle front panel of a motor vehicle and a motor vehicle will be described. The vehicle front panel has a headlight.

All motor vehicles have a vehicle front, which points in normal forward driving of the vehicle in the direction of travel forward. The vehicle front has a variety of tasks. On the one hand, it is a very important aerodynamic element, since it represents the first contact of the wind with the motor vehicle. On the other hand, the vehicle front is a succinct design element of the motor vehicle, which contributes decisively to the impression of the motor vehicle. In addition, the vehicle front has a variety of functions. These functions usually include street lighting, collision protection and many motor vehicles, especially internal combustion vehicles, cooling the drive.

In electric vehicles, the cooling requirement is usually much lower than in internal combustion vehicles. For this reason, the vehicle front can be made much more closed in electric vehicles, which benefits on the one hand the aerodynamics and on the other hand the safety. Vehicle front panels of electric vehicles are generally made larger area than in internal combustion vehicles.

The design of the headlights is given great importance. On the one hand, modern headlamp systems should be compact, on the other hand they should achieve a very good illumination of the road and, moreover, should represent a representation of the motor vehicle. Some motor vehicles also have dynamic headlight systems, whose light distribution can be adapted situationally.

The EN 20 2015 102 169 U1 discloses a hidden illuminated cooling water tank lid of a car comprising a decorative base of the cooling water tank lid, an LED light chain and a decorative lid. The Dekosockel can be designed in adaptation of different car models. At both ends of the Dekosockels a hole is provided in each case. The LED light chain is fixed between the decorative base and decorative cover. At each end of the light chain is each provided with an extended power cable that goes through the hole at the end of the Dekosockels to the back of the Dekosockels and connects to the electricity supplier of the car. The Dekodeckel is a housing made of a translucent material. It is designed to match the shape of the decorative base and surrounds the outside of the decorative base. The surface of the decorative lid is sputtered to create a sputtered layer on it and look like a mirror in the normal state. The sputtering layer can also transmit light from the inside to the outside.

The DE 10 2015 205 630 A1 relates to a cover device for at least partially covering a depression, a planar section, a curved section and / or a stepped section of at least one body component and / or a vehicle element of a vehicle, wherein the cover device has a lighting device or can be coupled to a lighting device and wherein the cover device is formed such that at least a portion of the cover device is transilluminable by means of the illumination device. The present invention further relates to a system comprising a cover device and a lighting device, a body component and a body component system, as well as a vehicle.

The GB 2516551 A discloses a lighting device for motor vehicles having a housing with an inner chamber and a light outlet. An illuminant is mounted in the inner chamber. An ionic membrane is disposed on the housing. The membrane has a dehumidifying side and a discharge side. The dehumidifying side is in fluid communication with the inner chamber so that moisture can be removed from the inner chamber.

The aforementioned systems of the prior art all have the disadvantage that an integration of lighting is always associated with joints, which on the one hand makes installation difficult, on the other hand adversely affects the aerodynamics and thirdly brings with it special challenges in terms of tolerances to be met.

Thus, the task of further developing a vehicle front panel and a motor vehicle of the type mentioned in that integration of lighting in a vehicle front panel without joint is possible.
