Description

[0001] The invention relates to a fastening arrangement for a lighting device of a motor vehicle having the features of the preamble of patent claim 1.

[0002] Such mounting arrangements are well known in the art. They serve to enable reliable and essentially vibration-free mounting of the lighting device on the motor vehicle.

[0003] The so-called "Total Cost of Ownership," or TCO for short, of a motor vehicle depends, among other things, on insurance costs. In many markets, these insurance costs are also influenced by the vehicle's insurance classification based on its technical specifications.

[0004] For the insurance classification (type class), a so-called RCAR structural test is conducted, which is intended to replicate part of a real accident scenario. During this test, the vehicle is driven at a relatively low speed (approximately 15 km / h) into a barrier inclined at a 10-degree angle around a vertical axis, with approximately 40 percent overlap of the vehicle's width. The repair costs are then determined based on the components damaged in the process, which are then incorporated into the type class classification.

[0005] Lighting systems, especially motor vehicle headlights, are typically a mechanically solid assembly. Due to the lighting requirements, the headlight housing and lens are designed to be very rigid. At the same time, such an assembly is becoming increasingly valuable due to the increasingly complex lighting technology.

[0006] In the case of motor vehicles in which lighting devices, in particular headlights, are positioned in such a way that they are directly or indirectly hit during the RCAR structural test, there is a risk of damage to these lighting devices and a risk of damage to other components due to an uncontrolled displacement of the hit lighting devices into the installation spaces behind them.

[0007] GB 1 430 026 A discloses a device for adjusting the height of a motor vehicle headlight. The device comprises a frame on which the headlight is mounted so that it can rotate about a horizontal axis. Changes in the vehicle's inclination relative to the road lead to a rotation of the reflector relative to the frame. A basic adjustment of the headlight's inclination can be made using an adjusting screw.

[0008] GB 2 370 105 A discloses a motor vehicle headlight with two interconnected reflectors forming a reflector unit whose inclination can be adjusted via an adjustment mechanism. A motor vehicle headlight with a comparable adjustment mechanism is also known from US 3 464 339 A.

[0009] GB 1 218 140 A describes a headlight unit that is adjustable and held in an opening in a vehicle body. Specifically, the headlight unit has two adjustment devices for vertical and lateral adjustment. The adjustment devices consist of U-shaped metal clamps whose U-shaped legs are connected to each other by adjusting screws. The adjusting screws are guided by bearings connected to the body. Turning the adjusting screws causes the headlight to rotate around a horizontal or vertical axis.

[0010] WO 2013 139 450 A1 shows a headlight of a vehicle lighting system, which comprises at least one housing, at least one illuminant and a cover plate.

[0011] DE 10 2008 017 899 A1 relates to a fastening arrangement for a headlight on a motor vehicle, which has a headlight housing accommodating at least one reflector with a cover plate closing said reflector on the light exit side, which is pivotally mounted on the vehicle and is provided with holding elements for fixing the headlight in a predetermined position.

[0012] From DE 10 2008 051 290 A1 a method for mounting a front-end module to a body shell of a vehicle, in particular a motor vehicle, as well as an arrangement for carrying out the method is known.

[0013] DE 603 ​​00 664 T2 shows a device for mounting a lighting unit on elements of the body of a motor vehicle, wherein the lighting unit has a housing closed by a pane, as well as members which connect the lighting unit to the body and allow the displacement of the lighting unit in the event of a frontal collision.

[0014] EP 3 501 894 A1 discloses a device for suspending a lamp in a vehicle. The device comprises a guide means for guiding the lamp in the event of an impact between the lamp and an object, so that it moves from a first position to a second position relative to the vehicle.

[0015] FR 2 895 954 A1 describes a mounting device for optical units, e.g. bumpers of a motor vehicle, which has a connecting unit that pivots about a vertical axis and a guide unit that is placed behind the housing of the optical unit to facilitate the tilting of the unit towards the outside of the vehicle in the event of an impact.

[0016] DE 60 2005 000 774 T2 shows a system for mounting a headlight on a vehicle and a vehicle with such a mounting system.

[0017] EP 1 048 521 A1 describes a lighting unit comprising mounting brackets with which the lighting unit is attached to a wing structure and to a cross member which is attached to the vehicle body.

[0018] EP 1 525 116 B1 discloses a fastening system for headlights on a carrier part of a vehicle with at least two plug connections arranged between the front and rear of the headlight, and with at least one snap connection associated with the plug connections.

[0019] The present invention is based on the object of providing a fastening arrangement for a lighting device of a motor vehicle, in which the risk of damage to the lighting device when hitting a barrier at low speed is reduced and the risk of damage to other components due to an uncontrolled displacement of the lighting device into installation spaces behind it is also reduced.

[0020] This object is achieved by a fastening arrangement having the features of patent claim 1. Advantageous embodiments or further developments of the invention can be found in the dependent claims.

[0021] The invention is based on a fastening arrangement for a lighting device of a motor vehicle. The lighting device can be, for example, a headlight for generating a low beam and / or high beam. However, other lighting devices are also conceivable, such as a daytime running light, a side light, a fog light, a turn signal, or the like. The lighting device is at least indirectly attached and / or mounted to a body of the motor vehicle via fastening areas.

[0022] According to the invention, it is proposed that the lighting device is fastened and / or mounted on the fastening areas in such a way that, when a specific limit value of an impact force on the lighting device is exceeded, the fastening of the lighting device can be automatically released, in such a way that the lighting device can perform a defined movement from its initial position (installation position) to a defined end position, wherein the lighting device is fastened or mounted on at least two fastening areas, wherein a first fastening area lies in a vertical axis about which the lighting device is rotatably mounted and a second fastening area serves to fix the lighting device, wherein, when the specific limit value of the impact force on the lighting device is exceeded, the fastening on the second fastening area can be automatically released, in such a waythat the lighting device can perform a rotational movement about the vertical axis, characterized in that the second fastening area is formed by a clamping connection, wherein the lighting device is held in its clamping position by at least one fastening means, wherein the clamping connection is formed by a clamping bearing into which a clamping element of the lighting device is inserted, wherein the clamping bearing has an insertion space with contact surfaces located opposite one another at clear distances, wherein the clear distances become smaller in a clamping direction of the clamping element and the contact surfaces interact with contact surfaces of the clamping element that converge in the clamping direction.

[0023] The movement can be a rotational movement. It is also conceivable that the movement is a linear movement or a combination of such movements.

[0024] This allows the lighting system to be moved in a controlled manner in the event of a low-speed crash (e.g., RCAR structural test). This ensures that the lighting device can be pivoted into predefined and appropriately clear installation spaces (or those occupied by components with low damage value) during the crash test. By preventing collisions with other components, the lighting system can be kept free of damage.

[0025] A very advantageous development proposes that the lighting device be attached or mounted on at least two fastening areas. A first fastening area lies along a vertical axis around which the lighting device is rotatably mounted. A second fastening area serves to fix the lighting device in a rotationally fixed manner, whereby if a certain limit value of the impact force on the lighting device is exceeded, the attachment to the second fastening area can be automatically released. This occurs in such a way that the lighting device can rotate around said vertical axis.

[0026] Such a further development makes it possible to achieve, with the greatest reliability, a desired hold of the lighting device during normal operation on the one hand and the desired release movement during a crash test on the other.

[0027] In another advantageous embodiment of the inventive concept, the second fastening region can be formed by a clamping connection, wherein the lighting device is held in its clamped position by at least one fastening means. Such a design allows the reliability of the fastening arrangement with the desired crash behavior to be ensured using simple means.

[0028] According to a further development, the clamping connection is formed by a clamping bearing into which a clamping element of the lighting device is inserted. The clamping bearing has an insertion space with contact surfaces arranged opposite one another at clear intervals. Viewed in the clamping direction of the clamping element, the clear intervals between the contact surfaces become smaller. The contact surfaces interact with contact surfaces of the clamping element that converge conically in the clamping direction. This further development contributes to reliable clamping and to the desired functionality of the fastening arrangement during crash testing.

[0029] A simple fixing of the lighting device can be achieved if the at least one fixing means fixes the clamping element of the lighting device in its clamping position, wherein the fixing means connects a front side of the clamping element facing forward (approximately in the direction of travel) to a front side of the clamping bearing that also faces forward.

[0030] It contributes to a structurally simple implementation of the fastening arrangement if the fastener is a screw for which the end face of the clamping bearing forms a support surface. The support surface of the clamping bearing is surrounded by recesses, similar to a predetermined breaking point. The recesses separate one wall of the end face from the support surface.

[0031] This also promotes a controlled and structurally easily adjustable release force, whereby the fastening device can release the lighting device for the purpose of a rotational movement around the vertical axis.

[0032] In a highly advantageous embodiment of the invention, the contact surfaces of the clamping bearing are part of an imaginary enveloping surface. A partial surface of the imaginary enveloping surface, pointing inwards towards an imaginary vertical center surface plane of the motor vehicle, has a radius running around the vertical axis. This radius increases counter to the clamping direction, starting from a first radius continuously to a second radius. Such a development contributes to the secure guidance of the lighting device during its movement towards the end position and prevents wedging during the relative movement between the clamping element and the clamping bearing during the release movement. A reliably functioning pivot bearing can be realized, for example, by the lighting device having a pivot pin on its underside, which forms the vertical axis and is accommodated in a pivot bearing of a console-like component.The console-like component is connected to the vehicle body. The clamping element, which interacts with the clamping bearing, is also connected to the underside of the lighting unit. The clamping bearing is adjustably connected to a console-like component, which in turn is connected to the body. These features not only ensure a secure fit for the lighting unit but also allow for easy adjustment relative to the body.

[0033] In order to promote a firm fit of the lighting device under normal operating conditions, it is also proposed that a second clamping element is connected to the underside of the lighting device, which second clamping element interacts with contact surfaces of an insertion area of ​​a second clamping bearing and forms a clamping connection therewith.

[0034] A further embodiment of the invention proposes that the lighting device be connected on its upper side to at least one locking component, which in turn is releasably locked to a clamp-like component. The clamp-like component itself is held in a displacement- and rotation-proof manner on a flat, elongated component, which in turn is connected to the body of the motor vehicle or is itself a body component. The elongated component has an elongated recess along which the locking component is moved, at least in sections, during the rotational movement of the lighting device about the vertical axis.

[0035] Such a further development contributes to a secure fastening of the lighting device during normal operation on the one hand and to a controlled release movement of the lighting device during a crash test on the other.

[0036] To improve the defined release of the lighting device, the clamp-like component can have two locking arms with locking lugs directed toward each other in the area of ​​the free ends. The locking component has a contact body that the locking arms enclose in a locking manner. The free ends of the locking arms are directed in the direction of the rotational movement.

[0037] It is very practical and further promotes a reliable release movement of the lighting device if, in the mounted position of the lighting device, the locking component and the clamp-like component touch each other via contact surfaces. The clamp-like component has flat contact surfaces on its underside, with which it rests on the flat, elongated component. On the upper side, the contact surfaces, which are inclined downwards toward an imaginary, vertical longitudinal center plane of the clamp-like component, touch the equally inclined contact surfaces of the locking component. This allows for very reliable fixation of the lighting device in the Z-direction (vertical direction) of the vehicle.

[0038] Furthermore, it is recommended that the upper contact surfaces slope downwards toward the free ends of the locking arms. In other words, the upper contact surfaces form an angle with the lower contact surfaces, which tapers conically toward the free ends of the locking arms, thus forming a wedge shape. During assembly of the lighting device, such a slight wedge shape of the contact surfaces in the insertion direction ensures that a clamping effect between the locking component, the clamp-like component, and the elongated component only takes effect at the end of an assembly movement. Conversely, after overcoming a release force, an unhindered release movement is facilitated.

[0039] In another embodiment, the locking component can be connected to the top of the lighting device via a screw. The screw's shaft can extend through an inner diameter of the locking component, and the inner diameter can be significantly larger than the outer diameter of the screw's shaft. This allows for a certain tolerance compensation during assembly of the lighting device.

[0040] Finally, in another embodiment of the invention, it is proposed that the lighting device have ribs on its upper side that are aligned approximately parallel to the direction of travel, with the ends facing away from the direction of travel facing and touching a contour of the flat, elongated component. The contour corresponds to a radius of the rotational movement after a crash-related detachment of the lighting device.

[0041] Such ribs can increase the stability and controllability of the rotational movement of the lighting device.

[0042] A preferred embodiment of the invention is illustrated in the figures and will be explained in more detail in the following description with reference to the figures. This also makes further advantages of the invention clear. The same reference numerals, even in different figures, refer to the same, comparable, or functionally identical components. Corresponding or comparable properties and advantages are achieved even if a repeated description or reference to them is not made. The figures are not, or at least not always, to scale. In some figures, proportions or distances may be exaggerated in order to emphasize features of an embodiment more clearly.

[0044] In Fig. 1 shows a motor vehicle K equipped with two fastening arrangements 1 according to the invention. The motor vehicle K can usually travel in one direction FR. MF denotes an imaginary vertical center plane of the motor vehicle K.

[0045] From the Fig. 2 and Fig. 3 shows the fastening arrangement 1 in perspective from obliquely above and obliquely below. The fastening arrangement 1 comprises a lighting device 10, which in the present embodiment is designed as the main headlight of the motor vehicle K.

[0046] The lighting device 10 comprises a housing 100, which is covered at the front by a cover plate 101.

[0047] On the underside of the housing 100, the lighting device 10 is indirectly connected to a structural component 12 of the body of the motor vehicle K on the outside of the vehicle via a first fastening area 14 and on the inside of the vehicle via a second fastening area 15.

[0048] The first fastening area 14 forms a vertical axis H around which the lighting device 10 can rotate. This will be explained in more detail later.

[0049] Specifically, the first mounting area 14 comprises a console-like component 140 with a pivot bearing 142, into which a pivot pin 106 of the housing 100 is received. The pivot pin 106 and the pivot bearing 142 are concentric with the vertical axis H.

[0050] The second fastening area 15 is formed by a clamping bearing 16, into which a clamping element 104 (see also Fig. 5a) is inserted in a clamping manner. The clamping element 104 is fixed in its clamping position by a fastening means 17 in the form of a screw. This will be described in more detail later.

[0051] The clamping bearing 16, in turn, is adjustably connected to a console-like component 13 via an adjusting means 19. The console-like component 13, in turn, is attached to a structural component 12 of the body.

[0052] Furthermore, it can be seen that the housing 100 of the lighting device 10 is attached to its upper side with a flat, elongated part 11 (so-called upper flange). The top and bottom fastening of the lighting device 10 ensures that it is securely and vibration-freely held to the motor vehicle K.

[0053] Based on the Fig. 4, the fastening arrangement 1 is shown in two states. Fig. 4a the lighting device 10 at the beginning of an impact on a barrier B, in a still unreleased state. The Fig. 4b, however, shows the lighting device 10 in a defined, rotated end position due to an impact force FA acting through the barrier B.

[0054] The figures show that the barrier B is rotated around a vertical axis at an angle α of preferably approximately 10 degrees relative to the vehicle's transverse direction. Furthermore, the barrier B overlaps approximately 40 percent of the width of the motor vehicle K. This corresponds to the test conditions in a so-called RCAR test.

[0055] At the moment of impact of the motor vehicle on the barrier B, the impact force FA acts on a contact point KP. This results in the lighting device 10 being released from its clamped position and a rotational movement D around the vertical axis H towards an end position ( Fig. 4b) is carried out.

[0056] Furthermore, it can be seen that the lighting device 10 is attached to the flat, elongated part 11 at its top via two upper attachment points 18.

[0057] Each attachment point 18 is formed by a locking component 181, which is connected to the housing 100 via a fastening means 180 in the form of a screw. The attachment points 18 are arranged in the region of elongated recesses 111a and 111b of the elongated part 11. The elongated recess 111a is designed as a slot open on one side, and the elongated recess 111b is designed as a closed slot. The regions of the attachment points 18 will be explained in more detail later.

[0058] Furthermore, the housing 100 has a component 102 on its upper side in the area of ​​the upper fastening point 18 on the outside of the vehicle, which component is provided with upwardly projecting ribs 103. The ribs 103 are aligned approximately parallel to the direction of travel FR. With their ends facing away from the direction of travel FR, the ribs 103 rest against a contour 111c (see dashed line) of the part 11. The contour 111c has a radius r2 that runs concentrically to a radius r1. The radius r1 represents a rotation radius within which the upper fastening points 18 move during the rotational movement D about the rotation axis H. A rotated end position of the lighting device 10 is designated 10'.

[0059] With the help of the ribs 103, additional guidance or support of the lighting device 10 can be ensured during the rotational movement D.

[0060] From the Fig. 5a shows how the clamping element 104 formed on the underside of the housing 100 is in its clamping position in the clamping bearing 16. The Fig. Figure 5b shows the clamping element 104 in a state in which it is located in front of an insertion space 160 of the clamping bearing 16, i.e., in front of its clamping position. The clamping element 104 is moved in a clamping direction KR toward the insertion space 160. On both lateral sides, the clamping element 104 has a semicircular clamping profile 104a, viewed in cross-section.

[0061] In Fig. 6 shows the second fastening area 15 in detail from its end face. Thus, the clamping bearing 16 has an end face 161. The end face 161 forms a support surface for the aforementioned fastening means 17. The support surface is separated from the remaining end face 161 by circumferentially arranged, elongated recesses 162.

[0062] As from Fig. 7, the fastening means 17, which is designed as a screw, engages with its shaft in a front-side thread of a front side 105 of the clamping element 104. In this way, the clamping element 104 is reliably held in its illustrated clamping position.

[0063] The recesses 162 create a defined predetermined breaking point which, when a certain limit value of the impact force FA is exceeded, causes the end face 161 to break out in the area of ​​the recesses 162 and the clamping element 104 to be released from its clamping position, whereby it can perform the already described rotational movement D opposite to the clamping direction KR.

[0064] In the Fig. Figure 8 shows the clamping bearing 16 with the clamping element 104 in detail. It is clearly visible that the insertion space 160 of the clamping bearing 16 has lower contact surfaces 163a and upper contact surfaces 163b.

[0065] As shown by the Fig. As can be seen in Figure 8a, lower contact surfaces 163a' and upper contact surfaces 163b' of the same design are arranged at a clear distance a on the opposite side of the insertion space 160. The contact surfaces 163a and 163b, or 163a' and 163b', respectively, complement each other to form a semicircular profile. In this way, a contact surface KF or KF', which is formed by the semicircular clamping profiles 104a, can be encompassed.

[0066] The contact surfaces 163a, 163a' and 163b, 163b' are part of rib-like projections 163c, 163c' and 163d, 163d', respectively. The rib-like projections 163c and 163d, respectively 163c' and 163d', are cut out alternately upwards and downwards. This allows undercuts to be avoided in the clamping bearing 16.

[0067] At the Fig. 8 it can further be seen that the contact surfaces 163a, 163b and 163a', 163b' lie on an imaginary enveloping surface HF.

[0068] A partial surface of this envelope HF inside the vehicle, i.e. to the imaginary center surface plane MF (compare Fig. 1), is formed by an outer radius ra, which runs around the vertical axis H. In particular, this radius ra increases in the direction of rotation D, which runs opposite to the clamping direction KR, from a smaller, outer radius ra1 to a larger, outer radius ra2.

[0069] The geometry described in this way is capable of transmitting both forces and moments when clamped.

[0070] A partial surface of the enveloping surface HF located outside the vehicle is generated in a similar manner. However, an inner guide radius ri satisfies the requirement that the distance from the outer radius ra increases over the course of the rotational movement D.

[0071] Based on the Fig. 9 and Fig. 10, the first fastening area 14 will be described in more detail. It can be seen that the fastening area 14 also has a clamping bearing comparable to the clamping bearing 16, at a short distance from the pivot pin 106 and the pivot bearing 142, with an insertion space 141 into which a clamping element 107 formed on the underside of the housing 100 can engage in a clamping manner. The clamping element 107 also has contact surfaces KF, which are formed by clamping profiles 107a of the clamping element 107 with a semicircular cross-section. The clamping surface KF interacts with lower and upper contact surfaces 141a, 141b and 141a', 141b'.

[0072] Furthermore, it can be seen that the clamping element 107 has a locking opening 107b on its front side, which serves to engage behind a locking hook 143 formed on the console-like component 140. In this way, the clamping element 107 is held in its clamping position.

[0073] The Fig. 11 is an upper attachment point 18 (see also Fig. 4) in an exploded view. This illustration shows a section of part 11 with the elongated recess 111a. The recess 111a is designed as an oblong hole open on one side. In the edge area of ​​the recess 111a, part 11 has two openings 112. These openings 112 serve to accommodate the underside fixing pins 182b (see also Fig. 12), with which a clamp-like component 182 is held on the component 11 in a rotationally and displacement-proof manner. The clamp-like component 182 has two parallel locking arms 182c, which, in an assembly position of the component 182, protrude towards the open side of the elongated recess 111a.

[0074] Furthermore, the locking component 181 is visible, which has an inner diameter 181a. The inner diameter 181a serves to guide the shaft of the fastening means 180, which is preferably designed as a screw. It can be seen that the inner diameter 181a is significantly larger than the diameter of the shaft of the fastening means 180. This allows for a certain tolerance compensation during assembly.

[0075] In the mounting position, the fastening means 180 engages in a thread of a movable snap nut 108, which is arranged on the housing 100 of the lighting device 10.

[0076] When mounting the lighting device 10 on the motor vehicle K, the upper fastening points 18 (cf. Fig. 4a). For this purpose, at each fastening point 18, the clamp-like component 182 with its fixing pins 182b is first positioned in the openings 112 of the part 11. Subsequently, the locking component 181 is pushed in from the open side of the clamp-like component 182 until it is locked, i.e. until the locking lugs 182d engage locking bevels 181f of an end face 181e of the locking component 181 (see also Fig. 13). The clamp-like component 182 has a U-shaped outline, with the locking arms 182c forming the U-legs and having two inwardly directed locking lugs 182d.

[0077] Then, the lighting device 10 is fastened to the second fastening area 15 and placed on the pivot bearing 142 (cf. Fig. 3). The lighting device 10 is now in such a position that the fastening means 180 can be inserted from above through the inner diameter 181a of the locking component 181 and screwed to the final assembly position using the snap nut 108 (see Fig. 11 and Fig. 13).

[0078] From the Fig. 12a and Fig. 12b, the contact surfaces with which the locking component 181 and the clamp-like component 182 rest against each other in the assembly position are clearly visible.

[0079] Thus, the locking component 181 has a contact body 181b, along which the locking lugs 182d are initially guided until they click into place. In the assembly position, the clamp-like component 182 then rests with a contact surface extending semicircularly in outline against a similarly extending contact surface of the contact body 181b.

[0080] Furthermore, the clamp-like component 182 has upper contact surfaces 182e. The upper contact surfaces 182e abut against the upper contact surfaces 181d of the locking component 181. Both the contact surfaces 182e and the contact surfaces 181d are inclined downward toward an imaginary longitudinal center plane of the components. This ensures good centering of the locking component 181 in the clamp-like component 182 in the assembly position.

[0081] On its underside, the clamp-like component 182 has lower contact surfaces 182a, which are flat and rest on a flat contact surface of the part 11.

[0082] Furthermore, it can be seen that web-like formations 182f protrude downwards from the inside of the lower contact surface 182a.

[0083] As shown by the Fig. As is clear from Figure 14, in the assembly position, the contact surfaces 181d of the locking component 181 and the contact surfaces 182e of the clamp-like component abut one another. The lower contact surfaces 182a are part of an outer wall 182g and an inner wall 182h of the clamp-like component 182. In the assembly position, the web-like projections 182f protrude into a space formed between a wall of part 11 and the contact body 181b.

[0084] With a lowermost contact surface, which also limits the inner diameter 181a on the underside, the locking component 181 rests on the housing 100 of the lighting device 10 in the area of ​​the aforementioned snap nut 108.

[0085] Finally, the Fig.13, it should also be mentioned that the upper contact surfaces 182e of the clamp-like component 182 and the upper contact surfaces 181d of the locking component 181 are inclined in the direction of free ends 182i of the locking arms 182c at an angle β in a wedge-like manner to the flat surface of the part 11. The wedge-like nature of the contact surfaces 182e, 181d ensures, in an assembly direction, that a clamping effect between the locking component 181, the part 11, and the clamp-like component 182 only comes into effect at the end of the assembly movement, and conversely, the parts can slide with little friction during release.
