Motor vehicle headlights (or also vehicle front elements) with a multipart housing are known from the prior art. It has the following advantages: the different components that perform the different functions of the motor vehicle headlight, or the different parts of the vehicle front, are housed in their own housings, which are manufactured on their own assembly lines. The production expenditure for the individual components is thereby optimized. Disadvantageously, the complexity of the entire housing and thus also of the finished motor vehicle headlight is increased by the number of raised sub-housings, thereby increasing the production costs of the motor vehicle headlight.
SUMMERY OF THE UTILITY MODEL
The object of the invention is to reduce or eliminate the disadvantages of the prior art. In particular, the invention thus sets the following objectives: a motor vehicle headlight is created, the installation space of which is optimized and the housing of which can be maintained and adapted more easily.
This object is achieved by a motor vehicle headlight, wherein the motor vehicle headlight comprises a housing, which is formed by a main housing part and at least one first and one second sub-housing part, wherein the first and second sub-housing parts are each arranged on the main housing part, wherein a first lighting device or a first sensor device is accommodated in the first sub-housing part and a second lighting device or a second sensor device is accommodated in the second sub-housing part, wherein the first lighting device and the second lighting device are each provided for generating and emitting light for a light function, wherein the first sensor device and the second sensor device are each provided for sensorially capturing the surroundings of the motor vehicle headlight, wherein the main housing part has a closure sheet which closes the main housing part, wherein the closure sheet is arranged at the front side of the main housing part, wherein the main housing part has at least one first opening and a second opening at a rear side facing away from the front side, wherein the first secondary housing part is arranged at the main housing part with first fastening means, wherein, in a coupled state, the first secondary housing part is fastened at the rear side of the main housing part such that light that can be generated with the illumination device can be emitted through the first opening of the main housing part and through a first region of the closure sheet of the main housing part, wherein the first region of the closure sheet is arranged substantially opposite the first secondary housing part, wherein the second secondary housing part is arranged at the main housing part with second fastening means, wherein, in a coupled state, the second secondary housing part is arranged at the rear side of the main housing part such that the sensor device can be obtained through the second opening of the main housing part and through the second region of the closure sheet of the main housing part The surroundings of the motor vehicle headlight are obtained, wherein the second region of the closure flap is arranged substantially opposite the second sub-housing part.
