Description

Technical Field

[0001] This invention relates to an adjustment system for adjusting, specifically pivoting, a light module of a vehicle headlight about a first rotation axis, wherein the adjustment system includes:

[0002] - The main assembly, which is stationary relative to the light module when the adjustment system is installed in the vehicle's headlight.

[0003] - An actuating element having a longitudinal axis about which it is rotatable, and having a threaded portion extending along the longitudinal axis.

[0004] - An adapter element for rotatably engaging with an actuating element, wherein the adapter element has a longitudinal axis and a mating threaded portion (or counter thread portion) extending partially along the longitudinal axis of the adapter element, the mating threaded portion corresponding to the threaded portion of the actuating element, wherein the actuating element is rotatably mounted on the adapter element by means of the mating threaded portion, wherein the engagement of the mating threaded portion with the threaded portion of the actuating element causes rotational movement of the actuating element and also includes linear movement of the actuating element relative to the adapter element along its longitudinal axis.

[0005] The adapter element is assembled onto the assembly body by means of a fixing device configured to secure the adapter element to the assembly body.

[0006] Furthermore, the actuating element includes a coupling element for mechanically engaging with the optical module to convert linear movement of the actuating element into pivotal movement of the optical module about a first rotation axis. Summary of the Invention

[0007] To enable the pivoting of optical modules or other optically related components, existing adjustment systems typically consist of several components to allow for efficient and safe pivoting of the optical module. Furthermore, assembling all components of such adjustment systems is complex and time-consuming.

[0008] The objective of this invention is to provide an enhanced adjustment system.

[0009] To achieve this goal, the adapter element includes at least one first engaging element and an adjacent element.

[0010] The assembly body includes an assembly opening having at least one recess corresponding to at least one first engaging element, and the fixing device includes at least one first mating engaging element.

[0011] The adapter element is brought to a middle position on the assembly body by inserting it into the assembly opening in the insertion direction, such that when the middle position is reached, at least one first engaging element passes through the assembly opening including at least one recess, and the abutting element abuts against the portion of the assembly body surrounding the assembly opening, thereby restricting the insertion movement of the adapter element into the assembly opening in the insertion direction.

[0012] Furthermore, the adapter element can be brought to its end position on the assembly body by rotating it from its intermediate position about its longitudinal axis, such that at least one first mating engagement element, together with at least one first engaging element and adjacent element, is rigidly locked to each other in such a way that the adapter element is fixed to prevent movement along its longitudinal axis.

[0013] Furthermore, the pivotal movement of the optical module about the first rotation axis caused by the actuating element causes the actuating element and the adapter element to pivot together about a pivot axis parallel to the first rotation axis, wherein the adjacent element

[0014] - It has a tapered shape extending radially outward from the longitudinal axis of the adapter element.

[0015] and / or

[0016] - Flexible construction,

[0017] This allows the adapter element and the actuating element to pivot about the pivot axis within an angular range of at least + / -1 degree around the zero position of the actuating element.

[0018] The term "rigid locking" is equivalent to "rigid connection." A rigid locking connection is created through the interlocking of at least two partners. As a result, the partners cannot disengage, whether the force transmission is uninterrupted or interrupted. In other words, in a rigid locking connection (or form-fit connection), one partner prevents another from disengaging.

[0019] Advantageously, the portion of the assembly body surrounding the assembly opening is constructed as a first mating engagement element, wherein the first mating engagement element, together with the first engagement element and the adjacent element, is rigidly locked to each other in such a way that the portion of the assembly body surrounding the assembly opening is located between the first engagement element and the adjacent element.

[0020] Advantageously, at least one first engaging element of the adapter element is constructed as a protrusion extending radially to the longitudinal axis of the adapter element.

[0021] Advantageously, the first engaging element is configured as a latching element, and the first mating engaging element is configured as a mating latching element, wherein when the adapter element reaches the end position, the latching element snaps into the mating latching element, wherein the latching element extends radially to the longitudinal axis of the adapter element.

[0022] Advantageously, the connecting element of the actuating element is constructed as a ball, wherein the mechanical engagement between the connecting element and the optical module is constructed as a ball joint.

[0023] Advantageously, the actuating element includes a stop element configured to abut against an adjacent element of the adapter element when a predetermined minimum stroke of the actuating element in the adapter element is reached, so as to limit the movement of the actuating element along the insertion direction.

[0024] In other words, when the stop element is adjacent to the adjacent element, the actuating element is fully screwed into the adapter element, which causes the light module to tilt or pivot to its maximum extent about the first axis of rotation, so that the light module pivots upward to the maximum extent in the correct mounting position of the adjustment system in the vehicle headlight.

[0025] Advantageously, the adapter elements are constructed as a single unit.

[0026] This objective is also achieved by a lighting device comprising at least one adjustment system and a light module according to the invention.

[0027] Advantageously, the optical module can be pivoted around a first rotation axis within an angular range of at least + / -1 degree around the zero position of the optical module by adjusting the system.

[0028] Advantageously, when the optical module is in the zero position, the actuation element is in the zero position.

[0029] This objective is also achieved by a motor vehicle headlight having at least one adjustment system according to the invention and / or a lighting device according to the invention. Attached Figure Description

[0037] Figure 1 An adjustment system 10 is shown for adjusting, specifically pivoting, the light module 20 of a vehicle headlight about a first rotation axis Y, wherein the adjustment system 10 includes a mounting body 100, which is stationary relative to the light module 20 when the adjustment system 10 is installed in the vehicle headlight.

[0038] Furthermore, the adjustment system 10 includes an actuating element 200 having a longitudinal axis A, the actuating element 200 being rotatable about its longitudinal axis A and having a threaded portion 210 extending along the longitudinal axis A.

[0039] Furthermore, the adjustment system 10 includes an adapter element 300 for rotatably engaging with the actuating element 200, wherein the adapter element 300 has a longitudinal axis B and a mating threaded portion 310 extending partially along the longitudinal axis B of the adapter element 300, the mating threaded portion 310 corresponding to the threaded portion 210 of the actuating element 200, wherein the actuating element 200 is rotatably mounted on the adapter element 300 by means of the mating threaded portion 310, wherein the engagement of the mating threaded portion 310 with the threaded portion 210 of the actuating element 200 causes rotational movement of the actuating element 200 and also includes linear movement of the actuating element 200 relative to the adapter element 300 along its longitudinal axis A.

[0040] The adapter element 300 is mounted on the assembly body 100 by means of a fixing device, which is configured to fix the adapter element 300 to the assembly body 100. Moreover, the adapter element 300 is constructed as a single integral part.

[0041] The actuating element 200 includes a coupling element 220 for mechanically engaging with the optical module 20 to convert linear movement of the actuating element 200 into pivotal movement of the optical module 20 about a first rotation axis Y.

[0042] In the example shown, the connecting element 220 of the actuating element 200 is constructed as a ball, wherein the mechanical engagement between the connecting element and the optical module 20 is constructed as a ball joint.

[0043] The adapter element 300 includes at least one first engaging element 300a and an adjacent element 320, which can, for example, in Figure 2 and Figure 4 I saw it in the middle.

[0044] The assembly body 100 includes an assembly opening 110 having at least one recess 111 corresponding to at least one first engaging element 300a, and wherein the fixing device includes at least one first mating engaging element 100a, wherein the adapter element 300 can be brought to a middle position on the assembly body 100 by inserting the adapter element 300 into the assembly opening 110 of the assembly body 100 in the insertion direction C, such that when the middle position is reached, at least one first engaging element 300a passes through the assembly opening 110 including at least one recess 111, and the abutting element 320 abuts against the portion of the assembly body 100 surrounding the assembly opening 110, thereby restricting the insertion movement of the adapter element 300 into the assembly opening 110 in the insertion direction C, such that... Figure 3 and Figure 5 As seen in the image.

[0045] The portion of the assembly body 100 surrounding the assembly opening 110 is thus constructed as a first mating engagement element 100a, wherein the first mating engagement element 100a, together with the first engagement element 300a and the adjacent element 320, is rigidly locked to each other in such a way that the portion of the assembly body 100 surrounding the assembly opening 110 is located between the first engagement element 300a and the adjacent element 320.

[0046] Furthermore, the adapter element 300 can be brought to the end position P2 on the assembly body 100 by rotating the adapter element 300 from the middle position about the longitudinal axis B of the adapter element 300, such that at least one first mating engagement element 100a together with at least one first engagement element 300a and adjacent element 320 are rigidly locked to each other in such a way that the adapter element 300 is fixed to prevent movement along the longitudinal axis B of the adapter element 300.

[0047] Furthermore, at least one first engaging element 300a of the adapter element 300 is configured as a protrusion extending radially to the longitudinal axis B of the adapter element 300, wherein the first engaging element 300a is also configured as a latching element, and the first mating engaging element 100a is configured as a mating latching element, wherein when the adapter element 300 reaches the end position P2, the latching element snaps into the mating latching element, wherein the latching element extends radially to the longitudinal axis B of the adapter element 300.

[0048] The pivotal movement of the optical module 20 about a first rotation axis Y, caused by the actuating element 200, causes the actuating element 200 and the adapter element 300 to pivot together about a pivot axis Y1 parallel to the first rotation axis Y. The adjacent element 320 has a radially outward tapering shape from the longitudinal axis B of the adapter element and is elastically constructed to allow the adapter element 300 and the actuating element 200 to pivot about the pivot axis Y1 within an angular range of at least + / - 1 degree around the zero position of the actuating element 200. Figure 6 The center is indicated by a dashed line.

[0049] Moreover, if it is possible Figure 5 and Figure 6 As seen in the diagram, the actuating element 200 includes a stop element 230, which is configured to abut against the abutment element 320 of the adapter element 300 when a predetermined minimum stroke of the actuating element 200 in the adapter element 300 is reached, so as to limit the movement of the actuating element 200 along the insertion direction C.

[0050] In other words, when the stop element 230 is adjacent to the adjacent element 320, the actuating element 200 is fully screwed into the adapter element 300, which causes the optical module 20 to tilt or pivot to its maximum extent about the first axis of rotation Y, so that the optical module 20 pivots upward to the maximum extent in the correct mounting position of the adjustment system 10 in the vehicle headlight.
