ADJUSTING ELEMENT FOR POSITIONING AN ADDITIONAL PART

Description

[0001] The invention relates to an adjustment element for positioning an attachment on a structural part of a vehicle. Furthermore, the invention relates to a lighting arrangement with the adjustment element, a method for mounting a lighting device in a vehicle, and a motor vehicle with the lighting arrangement.

[0002] For example, in the final assembly of vehicles, it is necessary to position and orient the components and assemblies that form the vehicle's surface relative to each other. This process is called adjustment and occurs in many joining processes along the entire value chain of the vehicle.

[0003] There are assemblies, such as lighting devices, that become part of the vehicle's surface. Such a lighting device could be, for example, a headlight assembly or a taillight, which is positioned in a recessed area of ​​the vehicle's surface during assembly. Here, it is essential to maintain tight tolerances, including those relating to gap dimensions between the headlight assembly or taillight and adjacent body panels. Tight tolerances also apply to the flush fit of the headlight assembly or taillight with the vehicle's surface. Excessive misalignment would result in a noticeable step within the vehicle's surface.

[0004] Experts are already familiar with numerous technical solutions that address the requirements described above. For example, it is known to position the lighting device in the receiving area of ​​the vehicle's surface and to attach it to a structural component of the vehicle. For subsequent adjustment, one or more adjustment elements can be provided to maintain the lighting device at defined points at a distance from the vehicle's surface. By adjusting these elements, the lighting device can then be moved relative to the vehicle's surface until the desired alignment is achieved.

[0005] This requires that the adjustment elements rest against the defined points on the vehicle's structural component to support the lighting device. A problem arises because the constant force and resulting continuous stress on the structural component often lead to local damage at these points. This can result in corrosion, for example, from damage to a protective paint finish applied to the structural component.

[0006] DE 87 13 935 U1 discloses a device for the adjustable connection of a vehicle headlight to a support element. This device has a retaining flange that can be inserted into a cutout in the support wall.

[0007] Furthermore, DE 199 26 842 A1 discloses a vehicle light with adjustable mounting. In this case, a threaded bolt is guided through a hole in a vehicle body and can thus hold the vehicle light at a distance from the vehicle body.

[0008] Furthermore, EP 0 393 353 A1 describes a headlight for vehicles. A reflector of the headlight is adjustable to a mounting part. The connection to the mounting part is made via two connecting parts, each of which is inserted into a bore in the mounting part and thus secured within it.

[0009] DE 101 21 114 A1 describes a vehicle light with adjustable mounting. The adjustability is achieved via a threaded bolt that can be attached to a vehicle structure in the direction of the adjustment.

[0010] DE 20 2007 016 945 U1 describes another adjustment element for the positionable fastening of a component, for example a vehicle light, in space.

[0011] Finally, DE 20 2005 008 060 U1 discloses a fastening arrangement for adjustable attachment of a housing part to a support part with the possibility of compensating for tolerances. The arrangement comprises a sleeve and a bolt-shaped fastening element that can be screwed into the sleeve. The arrangement further features a housing part with ribs into which a head of the sleeve is engaged, and in which the sleeve and the housing part form a rigid connection in the longitudinal direction.

[0012] FR 2 298 059 A1 discloses an adjustment element for positioning an attachment on a structural part of a vehicle. This element comprises an adjustment section and a mounting section, wherein the mounting section is movably mounted on the adjustment section and is attached to the adjustment section via a hinge connection. The mounting section is movably mounted on the adjustment section such that the support surface can pivot relative to the adjustment section.

[0013] EP 2 442 945 B1 discloses a further adjustment element for positioning an attachment on a structural part of a vehicle. This element comprises an adjustment section and a mounting section, wherein the mounting section is movably mounted on the adjustment section and is attached to the adjustment section via a hinge connection. The mounting section is movably mounted on the adjustment section such that the support surface can pivot relative to the adjustment section.

[0014] The invention is based on the objective of creating an adjustment element for positioning an attachment on a structural part of a vehicle, whereby the structural part does not experience any damaging influence from the adjustment of the attachment.

[0015] The problem is solved by the subject matter of claims 1, 3, 5 and 6. Further preferred embodiments of the invention result from the remaining features mentioned in the dependent claims.

[0016] A first aspect of the present invention relates to an adjustment element for positioning an attachment on a structural part of a vehicle, comprising an adjustment section that can be connected to the attachment and a contact section. The contact section is movably mounted on the adjustment section and has a support surface that can be placed against the structural part of the vehicle. The contact section is attached to the adjustment section via a hinge connection.

[0017] The adjustment section allows for the adjustment of geometric properties of the adjustment element, such as its length. The add-on part according to the invention can be any defrosting component required to complete the vehicle. This particularly applies to add-on parts intended for a specific area of ​​the vehicle's surface. Add-on parts in the form of lighting devices are particularly noteworthy in connection with the invention. The structural part according to the invention can accordingly be any structural part suitable for serving as a fixture, reference, or similar for positioning the add-on part. This particularly applies to structural parts in areas close to the vehicle's surface. Structural parts in the form of body panels are particularly noteworthy in connection with the invention.

[0018] The adjustment element according to the invention offers the advantage that any forces transmitted to the structural component via the adjustment element are transferred to the structural component as a surface load due to the support surface. This protects the material of the structural component and prevents wear resulting from high continuous stress. Thus, a major cause of corrosion damage is eliminated. Since the contact section with the support surface is movably mounted on the adjustment section, it is advantageously ensured that it can fully contact the structural component. The relative orientation of the adjustment element and the structural component is irrelevant. In other words, this is achieved by mounting the contact section movably on the adjustment section in such a way that the support surface can pivot relative to the adjustment section.In other words, the mobility between the mounting section and the adjustment section allows the support surface to be positioned relative to the adjustment section in such a way that the normal vector of the support surface can assume different angular relationships with an axis, for example, the longitudinal axis, of the adjustment section. This ensures that even with inherently warped structural components or those subject to manufacturing tolerances, the support surface remains in contact with the entire surface. The adjustment section allows for advantageously flexible, secure, and precise adjustment of the distance between the structural component and the attachment.For example, it is possible to first bring the support surface of the adjustment element's mounting section into contact with the structural part under preload, and then to adjust the adjustment section and thus, for example, to change the length of the adjustment element in order to achieve the desired alignment between the attachment and the structural part.

[0019] The joint connection can be designed for high stiffness. This allows high forces to be transferred from the structural component, via the support surface and the contact section, to the adjustment section and then to the attached component, without the adjustment element yielding. The adjustment element thus becomes significantly more resistant to thermal and mechanical environmental influences such as vibrations or heat. In this configuration, the adjustment section and the contact section can also be described as serial kinematics. The mobility of the contact section relative to the adjustment section in a joint connection, based on the respective centers of mass of these elements, can also be considered as the spatial displacement of the contact section relative to the adjustment section, since the relative position of the two centers of mass can change.Thus, the pivoting of the support surface relative to the adjustment section described above can result, for example, from the displacement of the entire system section.

[0020] In a further preferred embodiment of the invention, the joint connection comprises a joint body receptacle and a complementary sliding joint body.

[0021] The joint connection can, for example, be a ball and socket joint. The sliding joint body is then, for example, a ball joint, and the joint body receptacle is, for example, a socket joint. Such joint connections are advantageously easy to manufacture and simultaneously offer a high degree of mobility. By selecting suitable materials, such as plastic, it can also be ensured that additional lubrication is unnecessary and that the joint connection is simple and inexpensive to manufacture.

[0022] According to the invention, the adjustment section comprises a sleeve that can be connected to the attachment part and a support body that can be adjusted relative to the sleeve, on which the attachment section is mounted.

[0023] This offers the advantage that the adjustment element is very simple in design and at the same time enables all necessary functions.

[0024] Furthermore, according to the invention, the sleeve has an internal thread and the support body has an external thread.

[0025] This advantageously allows for simple, precise and safe adjustment of the sleeve and the support body relative to each other.

[0026] According to the invention, the sleeve is further provided that it can be connected to the attachment in a form-fitting and force-fitting manner. For this purpose, the sleeve has an external thread.

[0027] This advantageously ensures a secure connection between the sleeve and the attached component. Furthermore, the screw connection is detachable, thus offering flexibility in the event of replacement parts being needed.

[0028] A second aspect of the invention relates to a lighting arrangement for a vehicle, comprising at least one adjustment element according to the invention. In this case, the attachment referenced above is a lighting device for a vehicle. The structural part of the vehicle on which the lighting device is positioned can, for example, be a body panel or any other suitable structural part.

[0029] The lighting arrangement according to the invention offers advantages that are based on the advantages of the adjustment element according to the invention described above. Any forces transmitted to the structural component via the adjustment element are transferred to the structural component as a surface load due to the support surface of the adjustment element. This protects the material of the structural component and prevents wear resulting from continuous stress. Thus, a major cause of corrosion damage is eliminated. Since the mounting section with the support surface is movably mounted on the adjustment section, it is advantageously ensured that it can rest completely against the structural component. The relative orientation of the adjustment element and the structural component is irrelevant. This is particularly important in vehicle assembly. Here, the lighting device must be integrated into the overall visible appearance of the vehicle while adhering to tight tolerances.The precise relative final position between the lighting device and the structural component, such as a body panel, is difficult to predict. Similar difficulties arise with structural components that are inherently warped or subject to manufacturing tolerances. This can be compensated for by the movably mounted mounting section, ensuring that the mounting surface of the adjustment element always rests securely and evenly against the structural component. The adjustment section allows for advantageously flexible, secure, and precise adjustment of the distance between the lighting device and the structural component. For example, it is possible to first apply preload to the mounting section of the adjustment element to bring it into contact with the structural component, and then to adjust the adjustment section, thereby changing its length to achieve the desired alignment between the lighting device and the structural component.Thus, the adjustment element enables the position and orientation (including distance and angular rotation) of the lighting device relative to the structural part or body part.

[0030] In a preferred embodiment of the invention, the lighting arrangement further comprises the following features: the lighting device, which can be arranged in a receiving section of a surface of the vehicle; a bearing, by means of which the lighting device is movably mounted on the vehicle in at least one degree of freedom and can be displaced at least sectionally towards or away from the surface of the vehicle; and the adjustment element, the adjustment section of which is connected to the lighting device and the support surface of which can be placed on the structural part of the vehicle.

[0031] In other words, the surface of the vehicle is an enclosing surface that separates the vehicle from its environment. This enclosing surface can be formed, purely by way of example, by body panels, windows, and other components and assemblies that separate the vehicle from its environment. Accordingly, the term "receiving section" refers to the surface provided for the arrangement of a specific component or assembly, such that it completes the vehicle's surface within the receiving section. For the purposes of the invention, such an assembly is, in particular, a lighting device. Lighting devices, for the purposes of the invention, can be headlights, taillights, or other lighting devices known to those skilled in the art. The structural part of the vehicle lies, at least partially, below the vehicle's surface.The structural component can also form part of the vehicle's surface. The term "structural component" also implies structures consisting of multiple parts. The structural component is preferably a body panel of the vehicle that is visible in the receiving section of the surface as long as the lighting device has not yet been installed in that receiving section. In connection with the present invention, the structural component can also serve as a mounting for the lighting device. Alternatively, the lighting device can be positioned on the structural component and attached to the vehicle at a different location.

[0032] The lighting device is attached to the vehicle via a mounting and is movable in at least one degree of freedom. The mounting can, for example, be a pivoting joint. In this case, the lighting device would be pivotable around the mounting in at least one rotational degree of freedom. Alternatively, the mounting can be a plug connection that allows translational movement of the lighting device, for example, via bolts or pins. Movement of the lighting device towards the surface of the vehicle means that the lighting device is moved towards an area located behind the surface.

[0033] This could be, for example, the interior of the vehicle. Relocating the lighting device away from the surface of the vehicle, on the other hand, means that the lighting device is moved further away from the area behind the surface. Besides the interior of the vehicle, this could also be, for example, a structural component such as a body panel.

[0034] In a preferred embodiment of the invention, the lighting arrangement comprises an energy storage element which is configured to apply a preload force acting towards the surface of the vehicle to the lighting device.

[0035] The energy storage element can, purely by way of example, be a spring or a torsion spring. In the case of a torsion spring, the term "preload force" can also be used instead of "preload torque." However, a precise conceptual distinction between preload force and preload torque is unnecessary. In the context of the present invention, it is only crucial that the energy storage element can cause the preload force to accelerate the lighting device, either as a whole or locally, towards the surface of the vehicle. Thus, any preload torque applied to the lighting device always reappears as a local preload force at the lighting device via a certain lever arm. The preload force can be transmitted to the structural component via the adjustment element.This results in a closed force flow, via energy storage element, bearing, lighting device, adjustment element, the structural part, and via this or possibly via other areas of the vehicle back to the energy storage element.

[0036] This offers the advantage that the adjustment element can be permanently held in a position where the support surface rests against the structural component. In this state, the adjustment element can be adjusted particularly well.

[0037] A third aspect of the present invention relates to a method for mounting a lighting device in a vehicle, comprising at least the steps of: a) Pre-assembly of a lighting arrangement for a vehicle according to the present invention; b) Attaching a support surface of a mounting section of an adjustment element of the lighting arrangement according to the invention to a structural part of the vehicle; and c) Adjustment of the adjustment section.

[0038] The order of steps b and c can be chosen arbitrarily.

[0039] The method according to the invention offers the advantage that the lighting device can be mounted on the vehicle simply, quickly and safely.

[0040] Another aspect of the present invention relates to a motor vehicle comprising at least one lighting arrangement according to the invention.

[0041] Such a vehicle offers the advantage of a particularly clean and uniform external appearance. In particular, gap dimensions between the parts and assemblies forming the surface of the vehicle can be adjusted especially well with the lighting arrangement according to the invention. Furthermore, the quality of the vehicle according to the invention is significantly increased. Corrosion is one of the main problems in the automotive sector during operation. The lighting arrangement according to the invention eliminates a weak point of conventional vehicles in the vehicle according to the invention.

[0042] Unless otherwise stated in individual cases, the various embodiments of the invention mentioned in this application can be advantageously combined with one another.

[0043] The invention is explained in more detail below using exemplary embodiments and the accompanying drawings. These show: Figure 1 is a schematic representation of an adjustment element according to the invention in a preferred embodiment; Figures 2 to 4 are a schematic representation of a lighting arrangement according to the invention for a vehicle in a preferred embodiment; Figure 5 is a schematic representation of a method according to the invention for mounting a lighting device in a vehicle in a preferred embodiment; and Figure 6 is a schematic representation of a motor vehicle according to the invention in a preferred embodiment.

[0044] Figure 1Figure 1 shows an adjustment element 10 according to the invention in a preferred embodiment. The adjustment element 10 comprises an adjustment section 12 and a contact section 14, movable relative to the adjustment section 12, with a support surface 46. Because the contact section 14 is movable relative to the adjustment section 12, the support surface 46 can assume different angular relationships with respect to a longitudinal axis of the adjustment section 12. This longitudinal axis corresponds in Figure 1 of the intersection line AA. This possibility of the support surface 46 assuming different angular relationships with respect to a longitudinal axis of the adjustment section 12 can also be considered as the pivotability of the support surface 46 relative to the adjustment section 12. For example, consider Figure 4, thus it becomes clear that these angular relationships which the support surface 46 is able to assume relative to a longitudinal axis of the adjustment section 12 serve to compensate for an undesired angular adjustment W (more details in the description below).

[0045] The adjustment section 12 comprises a sleeve 16 and an adjustable support body 18. The adjustable support body 18 is longitudinally adjustable relative to the sleeve 16. For this purpose, the sleeve 16 has an internal thread 20 and the adjustable support body 18 has an external thread 21. The sleeve 16 and the adjustable support body 18 thus form a type of screw connection. The adjustment element 10 is adjustable by screwing the adjustable support body 18 into or out of the sleeve 16. A corresponding tool holder 44 is provided for this purpose. The contact section 14 is movably mounted on the adjustment section 12 via a hinge connection 22. The hinge connection comprises a sliding joint body 24 and a joint body receptacle 26. In this embodiment, the sliding joint body 24 is designed as a socket 27 and the joint body receptacle 26 is designed as a ball joint 25.The socket joint 27 is part of the assembly section 14. The socket joint 27 is freely slidable on the rod end 25 and is held by it via a clip connection. This free movement is limited only by the fact that the socket joint 27 forms an interference contour relative to the rod end 25, and vice versa. The assembly section 14 has a support surface 46 in the area of ​​the sliding joint body 24 or the socket joint 27. This support surface can be attached to a structural part 42 of a vehicle (not shown here) (see figure). Figures 3-5 The sleeve 16 can be connected to an attachment 50 (not shown here) via an external thread 23 (compare Figures 3-5 ).

[0046] Figure 2 Figure 1 shows a schematic representation of a lighting arrangement 28 according to the invention for a vehicle in a preferred embodiment. The lighting arrangement 28 comprises the adjustment element 10, as shown in Figure 2. Figure 1 depicted. The in Figure 1 The reference symbols used here also apply accordingly to Figure 2 The lower part of the Figure 2 shows a sectional view of the lighting arrangement 28. The section starts from the upper part of the Figure 2 The following is highlighted. Two section lines, A and B, are marked there. The corresponding section views AA and BB are identical and thus located in the lower part of the Figure 2 once shown.

[0047] The figure indicates a surface 30 of a vehicle, here a motor vehicle 32. The lighting arrangement 28 includes a lighting device 34 as an attachment 50. In this embodiment, this is a rear light. The lighting device 34 is arranged in a receiving section 36 of the surface 30. The lighting arrangement 28 further includes a mounting 52, by which the lighting device 34 is attached to the motor vehicle 32 so that it can be moved in one or more degrees of freedom. In this embodiment, the mounting 52 includes a stud bolt 54, which is attached to the motor vehicle 32 on one side and to the lighting device 34 on the other. An energy storage element 56 is also provided. In this embodiment, this is a spring 58, which is arranged on the stud bolt 54.This results in a preload force F acting on the lighting device 34 and in the direction of the motor vehicle 34.

[0048] In this embodiment, the adjustment element 10 is screwed into a housing 40 of the lighting device 34 via the external thread 23. The adjustment element 10 supports the lighting device 34 against the structural part 42 of the motor vehicle 34, counteracting the preload force F. The structural part 42 is a body panel 60. The interaction of the preload force F with the support effect of the adjustment element 10 can lead to an undesired angular adjustment W (see figure). Figures 3, 4) of the lighting device 34 relative to the motor vehicle 32. This is illustrated here by means of a pivot point P, the position of which can vary depending on the design of the specific lighting arrangement 28. The pivot point P is therefore shown here purely as an example. A resulting displacement of the lighting device 34 corresponds in this embodiment to a pivoting of the lighting device 34 about the pivot point P. Further explanation follows with reference to the Figures 3 and 4 These show detail area A from Figure 2 .

[0049] As in Figure 3As can be seen, the support surface 46 of the mounting section 14 of the adjustment element 10 lies flat against the body part 60. It is clearly evident that pivoting the lighting device 34 about the pivot point P results in an angular adjustment W. This angular adjustment W can be compensated for by the adjustment element 10, since the mounting section 14 is movably mounted on the adjustment section 12. Thus, the support surface 46 always lies flat against the body part 60. The angular adjustment W can also occur without pivoting the lighting device 34 about the pivot point P, for example, if the structural part 42 has a spatially twisted shape or due to unavoidable deviations in shape and position during manufacturing and assembly.

[0050] Furthermore, Figure 3It can be seen that the adjustment element 10 is adjustable along an adjustment path D. The adjustment is achieved by screwing the adjustable support body 18 into or out of the sleeve 16. This can be done with a suitable rotary tool via the tool holder 44. An adjustment of the adjustment element 10 in +d causes the lighting device 34 to be moved towards the body part 60 in the area of ​​the adjustment element 10. A corresponding adjustment of the adjustment element 10 in -d causes it to be moved away from the body part 60. This corresponds to a section-by-section movement of the lighting device 34 towards or away from the surface 30 of the motor vehicle 32.It should be noted that although the lighting device 34 has become part of the surface 30 of the motor vehicle 32 after assembly, this is not yet assumed for the adjustment itself, so that here the body part 60 is part of the surface 30. In the in . Figure 3 In the state shown, the lighting device 34 is displaced towards the surface 30 of the motor vehicle 32 up to a dead center in +d. In the present embodiment, an adjustment range D of 4 mm is available. Figure 5 is largely identical to Figure 3 The essential difference to Figure 3 The lighting device 34 is displaced from the surface 30 of the motor vehicle 32 along the adjustment path D to a dead center at -d. This results in an angular adjustment W in the opposite direction.

[0051] Figure 5Figure 1 shows a schematic representation of a method according to the invention for mounting a lighting device 34 in a vehicle in a preferred embodiment. The method for mounting the lighting device 34 comprises a first step a. In this step, a lighting arrangement 28 for a vehicle is pre-assembled. In the present embodiment, this is a lighting arrangement 28 as described in the Figures 2 to 4 as described. Therefore, to clarify the matter, reference is also made here to the reference symbols of the Figures 1 to 4 resorted to. The upper part of the Figure 5This section describes a first variant of the method. In a second step b, the support surface 46 of the mounting section 14 of the adjustment element 10 according to the invention is placed against the structural part 42 of the vehicle. In this embodiment, this is the motor vehicle 32. In a third step c, the adjustment section 12 of the adjustment element 10 is then adjusted. Alternatively, step c can also be performed before step b, as shown in the lower part of the Figure 5 depicted.

[0052] Figure 6 Figure 1 shows a schematic representation of a motor vehicle according to the invention in a preferred embodiment. The upper part of the Figure 6 Figure 32 shows the motor vehicle 32 according to the invention in a front view, the middle part of the Figure 6 shows the motor vehicle 32 in a rear view and the lower part of the Figure 6Figure 1 shows the motor vehicle 32 in a side view. The lighting arrangement 28 according to the invention can, for example, be provided in the area of ​​one or more headlights or taillights of the motor vehicle 32. However, the lighting arrangement 28 can, in principle, be provided with respect to any lighting devices or other attachments 50, which may be located both inside and on the outer surface 30 of the motor vehicle 32.
