[0001] The invention relates to a headlight for a motor vehicle, a motor vehicle comprising the headlight and a method for operating the headlight.

[0002] A headlight consists of a plastic housing and a transparent lens. The plastic housing contains a light module for daytime running lights and a main light module. A cornering light module is provided on the side of the headlight, particularly in premium headlights, which illuminates the area to the side of the vehicle when turning.

[0003] DE 202018102945 U1 discloses an exemplary headlight for a motor vehicle.

[0004] The headlight for a motor vehicle according to claim 1 provides that the headlight comprises a light module, in particular a cornering light or illuminated lettering, and an environment detection element, in particular an optical environment sensor, a radar or a camera, wherein the headlight has a housing, wherein the headlight has an area in the housing into which the light module or the environment detection element can be displaced, wherein the headlight comprises a changing device, wherein a change between the light module and the environment detection element can be carried out in the area using the changing device. As a result, the environment detection element can be displaced into the headlight instead of the light module, if necessary. Otherwise, the environment detection module is invisible in the headlight.For example, the cornering light module can be activated at night and, during automated driving, switched to the environment detection element, which is then in the same position.

[0005] The changing device preferably comprises a changing arm, wherein a guide axis is arranged on the housing, wherein the light module and the environment detection element are arranged on different sides of the guide axis on the changing arm, wherein the changing arm is rotatably movable about the guide axis from a first position to a second position, wherein the changing arm is arranged so as to be translationally movable on the guide axis, wherein the changing arm is arranged outside the housing, wherein the housing has a cutout, wherein the light module is movable in the first position of the changing arm by translationally moving the changing arm through the cutout into the housing or out of the housing, wherein the environment detection element is movable in the second position of the changing arm by translationally moving the changing arm through the cutout into the housing or out of the housing.The light module and the environment detection element are functional modules that can be arranged on the housing at different angles using interchangeable arms, depending on the available installation space.

[0006] Preferably, the light module and the environment detection element are arranged at opposite ends of the interchangeable arm. This means that the functional modules are arranged at a 180° angle on the interchangeable arm.

[0007] To carry out the translational movement, the headlight preferably comprises a movement piece, wherein the movement piece is mounted on the guide axis so as to be translationally movable, wherein the movement piece is designed to move the change arm translationally with respect to the housing during a translational movement of the movement piece.

[0008] Preferably, the headlight includes a drive for translationally moving the moving part. This means that the headlight represents an assembly including the translational drive.

[0009] For example, the drive for translationally moving the moving piece provides that the moving piece is arranged so as to be rotatably movable on the guide axis, wherein the moving piece has an external thread spindle extending along the guide axis, wherein the housing has an internal thread, wherein the external thread spindle engages in the internal thread, wherein a motor with a drive pinion is arranged on the changing arm, wherein the moving piece has a pinion that can be driven by the drive pinion for the rotational movement of the moving piece on the guide axis.

[0010] To implement the rotational movement, the spotlight preferably includes a drive for the rotational movement of the guide axis relative to the housing. This means that the spotlight represents an assembly including the rotational drive.

[0011] For example, the drive for the rotary movement of the guide axis on the housing provides that a motor with a drive pinion is arranged, wherein the guide axis has a pinion that can be driven by the drive pinion for the rotary movement of the guide axis.

[0012] For example, the guide axis supports the change arm via a bearing. For example, the housing accommodates the guide axis via a guide.

[0013] A motor vehicle may be provided which includes the headlight.

[0014] A method for operating the headlight provides that the changing device is used to change between the light module and the environment detection element in the area.

[0015] The method can provide that the light module is moved in the first position of the interchangeable arm by translational movement of the interchangeable arm through the cutout in the housing, wherein the interchangeable arm is moved rotationally about the guide axis from the first position into the second position, wherein the environment detection element is moved in the second position of the interchangeable arm by translational movement of the interchangeable arm through the cutout in the housing, or that the environment detection element is moved in the second position of the interchangeable arm by translational movement of the interchangeable arm through the cutout in the housing, wherein the interchangeable arm is moved rotationally about the guide axis from the second position into the first position, wherein the light module is moved in the first position of the interchangeable arm by translational movement of the interchangeable arm through the cutout in the housing.

[0054] The translational movement 312 is achieved by rotating the motor 304 arranged on the change arm 106 in the opposite direction of rotation 313.

[0055] The same procedure is followed for moving the environment detection element 105 out of the housing 101 and for moving the light module 104 into the housing 101.

[0056] This means that the environment detection element 105 is moved out of the housing 101 in the second position of the interchangeable arm 106 by translationally moving the interchangeable arm 106 through the cutout 110. The interchangeable arm 106 is then rotated about the guide axis 107 from the second position to the first. Subsequently, the light module 104 is moved into the housing 101 in the first position of the interchangeable arm 106 by translationally moving the interchangeable arm 106 through the cutout 110.
