[0002] The headlight comprises a plastic housing and a transparent disc. The main lamp module and the lamp module for the low beam are arranged within the plastic housing. In the lateral area, particularly for the advanced headlight, a cornering light module is provided that illuminates the lateral area adjacent to the motor vehicle when turning.
[0003] DE 202018102945 U1 discloses an exemplary headlight for a motor vehicle. Summary of the Invention
[0004] The headlight for motor vehicles according to the invention is characterized by comprising a lamp module, particularly a turn signal or luminous marker; and an environmental sensing element, particularly an optical environmental sensor, radar, or camera. The headlight includes a housing containing a region within which the lamp module or environmental sensing element can be displaced. The headlight includes a replacement device in which replacement between the lamp module and the environmental sensing element can be performed in this region. Thus, the environmental sensing element can be displaced into the headlight as needed to replace the lamp module. Otherwise, the environmental sensing module is invisible in the headlight. For example, at night, the turn signal module can be activated, and during autonomous driving, the turn signal module can be switched to the environmental sensing element, which subsequently remains in the same position.
[0005] Preferably, the replacement device includes a replacement arm, wherein a guide shaft is arranged on the housing, and the lamp module and environmental sensing element are arranged on the replacement arm and located on different sides of the guide shaft. The replacement arm is rotatably movable from a first position to a second position about the guide shaft. The replacement arm is arranged on the guide shaft for translational movement. The replacement arm is located outside the housing, which includes an opening. When the replacement arm is in the first position, the lamp module can move into or out of the housing through the opening by means of the translational movement of the replacement arm. When the replacement arm is in the second position, the environmental sensing element can move into or out of the housing through the opening by means of the translational movement of the replacement arm. The lamp module and environmental sensing element are functional blocks, and these functional blocks can be equipped with replacement arms, which are positioned at different angles on the housing depending on the available design space.
[0006] Preferably, the lamp module and the environmental sensing element are arranged at opposite ends of the changing arm. This means that the functional blocks are arranged on the changing arm at an angle of less than 180°.
[0007] In order to perform translational movement, the headlight preferably includes a moving member, wherein the moving member is supported for translational movement on a guide shaft, wherein the moving member is configured to cause the replacement arm to translate relative to the housing during the translational movement of the moving member.
[0008] Preferably, the headlight includes a drive mechanism for moving the moving part in a translational manner. That is, the headlight refers to an assembly that includes a translational drive mechanism.
[0009] For example, the drive provides translational motion of the moving part in such a way that the moving part is arranged on the guide shaft in a rotatable manner, wherein the moving part includes an externally threaded spindle extending along the guide shaft, wherein the housing includes an internal thread, wherein the externally threaded spindle engages with the internal thread, wherein an electric motor having a drive pinion is arranged on the changing arm, wherein the moving part includes a pinion that can be driven by the drive pinion to achieve rotational motion of the moving part on the guide shaft.
[0010] In order to perform rotational movement, the headlight preferably includes a drive mechanism for the rotational movement of the guide shaft relative to the housing. That is, the term "headlight" refers to an assembly that includes a rotational drive mechanism.
[0011] For example, the drive for the rotational movement of the guide shaft on the housing is achieved by the following method: the motor is arranged with a drive pinion, wherein the guide shaft includes a pinion that can be driven by the drive pinion to achieve the rotational movement of the guide shaft.
[0012] For example, the guide shaft supports the changing arm via bearings.
[0013] For example, the housing receives the guide shaft via a guide member.
[0014] A motor vehicle including headlights can be provided.
[0015] A method for operating a headlight includes: the replacement of the lamp module and the environmental sensing element in a region is carried out using a replacement device.
[0016] The method can provide that: when the replacement arm is in a first position, the lamp module is moved out of the housing through an opening by means of the translational movement of the replacement arm, wherein the replacement arm is rotatably moved from the first position to a second position about a guide shaft, wherein when the replacement arm is in the second position, the environmental sensing element is moved into the housing through the opening by means of the translational movement of the replacement arm; or when the replacement arm is in the second position, the environmental sensing element is moved out of the housing through an opening by means of the translational movement of the replacement arm, wherein the replacement arm is rotatably moved from the second position to the first position about a guide shaft, wherein when the replacement arm is in the first position, the lamp module is moved into the housing through the opening by means of the translational movement of the replacement arm.

[0036] exist Figure 3The image shows a cross-sectional view of a headlight 100, in which a functional block (lamp module 104 in the example) is located in the headlight 100 (i.e., in the housing 101).
[0037] The headlight 100 includes a moving part 302.
[0038] The headlight 100 includes a drive mechanism for moving the moving part 302 in a translational manner.
[0039] Figure 3 An example of a drive device for moving the moving part 302 in a translational manner is shown.
[0040] The moving part 302 is rotatably arranged on the guide shaft 107.
[0041] The moving part 302 includes an externally threaded spindle 302 extending along the guide shaft 107.
[0042] The housing 101 includes an internal thread 303.
[0043] The external thread spindle 302 engages with the internal thread 303.
[0044] An electric motor 304 with a drive pinion 305 is arranged on the changing arm 106.
[0045] The moving part 301 includes a pinion 306 that can be driven by a drive pinion 305 to achieve rotational movement of the moving part 301 on the guide shaft 107.
[0046] The guide shaft 107 supports the changing arm 106, for example, via a bearing 307.
[0047] The housing 101 receives the guide shaft 107, for example, via the guide 308.
[0048] The headlight 100 includes a drive mechanism for rotatably moving the guide shaft 107 relative to the housing 101.
[0049] Figure 3 An example of a drive device for the rotational motion of moving part 302 is shown.
[0050] For example, the drive for the rotational movement of the guide shaft 107 on the housing 101 is achieved by arranging a drive pinion 110 on the motor 309.
[0051] For example, the drive device for the rotational movement of the guide shaft 107 on the housing 101 is implemented in such a way that the guide shaft 107 includes a pinion 311 that can be driven by the drive pinion 310 to realize the rotational movement of the guide shaft 107.
[0052] exist Figure 4The image shows a cross-sectional view of a headlight 100, wherein the lamp module 104 is located outside the headlight 100, that is, outside the housing 101.
[0053] refer to Figure 3 and Figure 4 A method for operating the headlight 100 is described.
[0054] The method includes replacing the lamp module 104 and the ambient sensing element 105 in the area of the headlight 100 (i.e., in the housing 101) using a replacement device.
[0055] Figure 3 and Figure 4 The replacement arm 106 is shown in the first position.
[0056] The method includes: when the replacement arm 106 is in a first position, the lamp module 104 is moved out of the housing 101 through the opening 110 by means of a translational movement 312 of the replacement arm 106. The translational movement 312 is achieved by rotating a motor 304 arranged on the replacement arm 106 in the rotational direction 313.
[0057] The method includes: the replacement arm 106 subsequently rotating about the guide shaft 107, that is, rotating from a first position to a second position by a rotational movement 314. The rotational movement 314 is achieved by rotating a motor 309 arranged on the housing 101 in the rotational direction 315.
[0058] The method includes: when the replacement arm 106 is in the second position, the environmental sensing element 105 then moves into the housing 101 through the opening 110 by means of the translational movement of the replacement arm 106.
[0059] Translational motion 312 is achieved by rotating the motor 304 arranged on the changing arm 106 in the opposite direction to the rotation direction 313.
[0060] As the environmental sensing element 105 is removed from the housing 101 and the lamp module 104 is moved into the housing 101, the operation continues accordingly.
[0061] In other words, when the replacement arm 106 is in the second position, the environmental sensing element 105 is moved out of the housing 101 through the opening 110 by means of the translational movement of the replacement arm 106. The replacement arm 106 then rotates about the guide shaft 107 from the second position to the first position. Subsequently, when the replacement arm 106 is in the first position, the lamp module 104 moves into the housing 101 through the opening 110 by means of the translational movement of the replacement arm 106.
