Description

[0001] The invention relates to an arrangement for positioning and fastening a light to a body part of a vehicle according to the combination of features of claim 1 of the invention. According to claim 10 of the invention, the same further relates to a vehicle with such a positioning and fastening arrangement.

[0002] From the practice of vehicle construction, in particular motor vehicle construction, it is known to arrange and fasten lights in a mounting opening of a body part, such as a vehicle's tailgate. Assembly is still predominantly carried out manually and requires careful positioning of the light in said mounting opening, which can involve considerable effort, particularly physical exertion. To do this, it is necessary, for example, to first insert the light orthogonally to the mounting opening or to a light receptacle arranged therein, then to move the light into a final position by a lateral movement and finally to fasten it to the body part, such as the said tailgate, by means of at least one mechanical fastening element.The positioning of the luminaire by a worker involves moving it in at least two different spatial directions, resulting in increased assembly effort. There is a need to minimize this effort and make the assembly process reproducible.

[0003] DE 103 53 374 A1 shows a fastening arrangement for a headlight on a vehicle, with a headlight housing with a lens covering a light exit opening, in which the headlight is arranged in a recess on a body part and is connected to this and can be moved between an operating position and a non-operating position given in the vehicle longitudinal direction in front of the operating position.

[0004] DE 10 2014 104 923 A1 discloses a body structure of a motor vehicle with an add-on element, wherein the add-on element is positioned in a receiving pot of the body structure, aligned in the receiving pot relative to the body structure and fastened to the body structure via fastening elements, wherein the add-on element is roughly centered relative to the body structure via a plurality of centering elements in the receiving pot and finely centered relative to the body structure via a plurality of tolerance compensation elements in the receiving pot.

[0005] The object of the invention is therefore to provide an arrangement for positioning and fastening a light to a vehicle body part that is cost-effective while ensuring secure and reproducible installation. A further object of the invention is to provide a vehicle with such a positioning and fastening arrangement.

[0006] The stated object is achieved by an arrangement for positioning and fastening a lamp to a body part of a vehicle, wherein the body part has a lamp holder in which the lamp is positioned by means of a positioning device and fastened by means of at least one mechanical fastening element, wherein the lamp holder has a receiving base and the positioning device has at least one guide element arranged on a housing of the lamp and supported on a first side edge or side wall of a first bottom opening of the receiving base, as well as at least one stop supported on a second side edge or side wall of the first or a second bottom opening of the receiving base, arranged opposite to the first side edge or side wall, and wherein the at least one guide element is designed and / or constructed in such a way thatthat only by an assembly force ‘F’ directed orthogonally into the luminaire holder and acting on the luminaire M “ a forced positioning of the luminaire in the luminaire holder, resulting from a superimposed movement of the luminaire orthogonal to the luminaire holder and laterally towards the second side edge or side wall of the first or second floor opening of the holder base.

[0007] This advantageously minimizes assembly effort, especially the effort required to position the luminaire in the fixture, since simply pressing the luminaire orthogonally into the fixture by the operator also causes the required or desired lateral movement of the luminaire within the fixture. Furthermore, additional alignment work and assembly aids are unnecessary, as the guide element ensures that the luminaire is guided into the desired position during installation.

[0008] The subclaims describe preferred developments or embodiments of the invention.

[0009] According to an advantageous embodiment of the invention, it is provided that the at least one guide element is oriented obliquely to the orthogonal direction of movement of the luminaire towards the luminaire receptacle and / or is formed obliquely at least in sections in such a way that as a result of contact and sliding of the guide element onto the first side edge or side wall, a transverse movement of the luminaire towards the second side edge or side wall is effected until the stop touches said second side edge or side wall.

[0010] Furthermore, it is provided that the guide element is elastically pre-tensioned against the first side edge or side wall, whereby the light is fixed in the desired position, in particular by frictional engagement, until the light is mechanically fastened to the body part.

[0011] In order to further simplify the installation of the lamp on the body part, the housing of the lamp has at least one means for pre-fixing the lamp to the body part.

[0012] According to a practical embodiment of the invention, the at least one means for pre-fixing is formed by a hook element which is mounted in the first or second bottom opening or a further bottom opening of the lamp holder so as to be displaceable in the direction of the second side edge or side wall.

[0013] Advantageously, the at least one guide element and the at least one stop are formed integrally with the housing of the luminaire, which can be realized particularly simply and cost-effectively in a housing that is manufactured, for example, using a plastic injection molding process.

[0014] As for the light mount, it is advantageously designed in a cup shape, which allows the light to be recessed within the bodywork, thus largely not protruding from it. The final fixation is achieved by the aforementioned mechanical fastening element.

[0015] The light can, for example, be formed by a rear light of the vehicle, which is attached to a body part in the form of a tailgate of the vehicle.

[0016] The invention also relates to a vehicle with an arrangement of the type described above.

[0017] The invention is explained in more detail below with reference to an exemplary embodiment shown schematically in the drawings. However, it is not limited to this embodiment, but covers all configurations defined by the patent claims. For the purposes of the present description, the usual direction of travel of a vehicle, in particular a motor vehicle, is denoted by "-x" ("minus x"), the direction opposite to its usual direction of travel is denoted by "+x" ("plus x"), starting from the usual direction of travel (-x) the horizontal direction perpendicular to the x-direction to the right is denoted by "+y", starting from the usual direction of travel (x) the horizontal direction perpendicular to the x-direction to the left is denoted by "-y", the vertical direction perpendicular to the x-direction upwards is denoted by "+z", and the vertical direction perpendicular to the x-direction downwards is denoted by "-z".This Cartesian coordinate system for spatial directions corresponds to the coordinate system commonly used in the automotive industry, particularly the motor vehicle industry. Furthermore, terms such as "front," "rear," "top," "bottom," and similarly connoted terms, including "right" and "left," are used in the manner commonly used to indicate directions on a vehicle, particularly a motor vehicle. The figures show: Fig. 1 extremely schematic a rear view of a vehicle, Fig. 2 a detailed view of a body part of the vehicle according to Fig. 1 in the form of a tailgate, with a light or rear light built into the same, Fig. 3 a single view of a tailgate light fixture seen from inside the vehicle, fitted with the light, Fig. 4 the detail “Z” according to Fig. 3, Fig. 5 the detail “Y” according to Fig. 3, Fig. 6 the section “II” according to Fig. 4, and Fig. 7 the cut “I II I” after Fig. 5.

[0018] Fig. 1 shows a rear view of a vehicle 1, in this case a passenger car. A rear opening of the vehicle is closed by means of a body part 2 pivotally attached to the body of the vehicle 1. Said body part 2 is a tailgate 2a of the vehicle 1. The body part 2 or said tailgate 2a consists of a welded assembly comprising an outer part 3, an inner part 4 and, as viewed in the vehicle's transverse direction (Y-direction), a pot-shaped light receptacle 6 on each side inserted into an opening 5 of the outer part 3, in which a light 7 or rear light 7a, 7b is recessed (cf. Fig. 3, Fig. 6 and Fig. 7). The invention is described below using the example of the left-hand light 7 or rear light 7a attached to the tailgate 2a. The right-hand rear light 7b is largely identical to the left-hand rear light 7a.

[0019] According to the Fig. 6 and Fig. 7, the lamp 7 or rear lamp 7a is known to have a housing 8, a transparent pane 9 attached to the same and electrical and / or electronic components 10 (cf. Fig. 3). By means of a sealing element 11, the luminaire 7 is supported in the installed state on a receiving base 12 of the luminaire holder 6 and is secured by means of at least one mechanical fastening element 13 (cf. Fig. 3), such as a screw, to the receiving base 12.

[0020] According to the Fig. 3 to 7, the lamp 7 has a positioning device 14, particularly with regard to the assembly process itself. This comprises at least one guide element 15 arranged on the lamp housing 8, preferably formed integrally therewith, which is supported on a first side edge or side wall 16 of a first bottom opening 17 of the receiving base 12 of the lamp receptacle 6. In addition, the lamp housing 8 comprises at least one stop 18, preferably also formed integrally with the lamp housing 8, which stop 18, according to this exemplary embodiment, is supported on a second side edge or side wall 19 of a second bottom opening 20 of the receiving base 12 of the lamp receptacle 6, viewed in the vehicle transverse direction (Y direction), arranged opposite the first side edge or side wall 16 of the first bottom opening 17.Alternatively, the stop 18 can also be supported on a second side edge or side wall 19 of the first floor opening 17 of the receiving base 12 of the lamp holder 6, which second side edge or side wall 19 is arranged opposite to the first side edge or side wall 16 of the first floor opening 17 (not shown in the drawing).

[0021] The guide element 15 is in particular designed and / or constructed in such a way that solely by means of an assembly force “F” directed orthogonally or largely orthogonally into the luminaire holder 6 and acting on the luminaire 7, the guide element 15 is guided in the direction of the arrow “F” M “ (cf. Fig. 6 and Fig. 7) a forced positioning of the luminaire 7 in the luminaire holder 6 occurs. This forced positioning results from a superimposed movement of the luminaire 7 orthogonal to the luminaire holder 6 and laterally toward the second side edge or side wall 19 of the present second floor opening 20 of the holder base 12.

[0022] For this purpose, the guide element 15 is inclined to the orthogonal direction of movement 21 of the luminaire 7 during assembly, corresponding to the effective direction of the assembly force “F M “, towards the lamp holder 6, and / or at least partially formed obliquely such that as a result of contact and sliding of the guide element 15 onto the first side edge or side wall 16, a transverse movement of the lamp 7 towards the second side edge or side wall 19 is effected until the stop 18 touches said second side edge or side wall 19 (cf. directional arrow 22 or 23 in the Fig. 4 and Fig. 5).

[0023] Preferably, the guide element 15 is elastic, in particular spring-elastic, whereby the same is tensioned during the insertion of the lamp 7 into the lamp holder 6 and thus on the one hand supports the movement of the lamp 7 towards the second side edge or side wall 19 and on the other hand has a pre-tension in the mounted state, which more preferably fixes the lamp 7 in this position until the aforementioned at least one mechanical fastening element 13 is attached.

[0024] Like the Fig. 3 and Fig.5, the lamp housing 8 has a means 24, preferably also formed integrally with the same, for pre-fixing the lamp 7 to the body part 2, in this case to the tailgate 2a. The said means 24 for pre-fixing is formed merely by way of example by a hook element 24a, which is mounted in the second bottom opening 20 of the lamp holder 6 or its receiving base 12 so as to be displaceable in the direction of the second side edge or side wall 19. Alternatively, it can also be provided that the means 24 for pre-fixing, designed as a hook element 24a in this case, is mounted in the first bottom opening 17 or a further bottom opening (not shown in the drawing) of the lamp holder 6 or its receiving base 12.This allows the worker, in preparation for the actual assembly, to first hang the luminaire 7 in the floor opening 20 and / or to support it in the same and then to carry out the actual assembly as described above.
