DETAILED DESCRIPTION

(14) This disclosure relates generally to a lamp of a vehicle. The vehicle can include removable outer panels.

(15) During assembly, one of the outer panels is first secured to a body structure of the vehicle in an installed position. Next, an alignment fixture is used to position a mounting bracket relative to the outer panel. Once positioned, the mounting bracket is secured to the body structure. The alignment fixture is then removed, and a lamp is secured to the mounting bracket. Since the mounting bracket was positioned relative to the outer panel and the lamp is secured to the mounting bracket, the position of the lamp relative to the outer panel is controlled.

(16) Controlling the positioning of the lamp relative to the outer panel can help to maintain desired spacing between the lamp and the outer panel, which can facilitate meeting appearance goals. Due to the alignment fixture, the positioning of the lamp relative to the outer panel can be controlled without the lamp directly engaging the outer panel. Because the lamp does not directly engage the outer panel, the outer panel is able to be removed from the body structure while the lamp remains secured to the body structure through the mounting bracket. The alignment fixture substantially transfers lamp locators from the outer panel to the body structure.

(17) With reference to FIG. 1, an example vehicle 10 includes a plurality of outer panels 14, 18, and a plurality of lamps 22, 26. The outer panel 14 is a front fender, and the outer panel 18 is a rear quarter panel. The lamp 22 is a headlamp, and the lamp 26 is a taillamp. At least the outer panel 18 is removable. A user may wish to remove the outer panel 18 and replace it with a different outer panel to change an appearance of the vehicle 10.

(18) With reference now to FIG. 2, the outer panel 18 can be secured to a body structure 30 of the vehicle 10 in an installed position. The outer panel 18 can be secured to the body structure 30 with a plurality of mechanical fasteners 34, such as bolts.

(19) Generally, the body structure 30 is a rigid, or fixed, part of the vehicle 10. Requirements may necessitate that each lamp of the vehicle 10, such as the lamps 22 and 26, remain secured to a rigid part of the vehicle 10 unless repair of the lamps 22 and 26 is required. The body structure 30 can include rigid parts of the vehicle 10 such a bodyside, pillar structure, a front floor, under floor, frame, engine compartment, etc. Here, the body structure 30 is an upper body structure.

(20) In this exemplary embodiment, a user can remove the outer panel 18 from the vehicle 10 by disengaging the mechanical fasteners 34. Once disengaged, the outer panel 18 can be removed from the body structure 30 as shown in FIG. 3. Notably, the lamp 26 can remain mounted to the body structure 30 as the outer panel 18 is removed. That is, demounting the lamp 26 from the body structure 30 is not required to remove the outer panel 18. Thus, the outer panel 18 can be removed and replaced while meeting requirements to keep the lamp 26 secured.

(21) As shown in FIG. 4, there are gaps G between the outer panel 18 and the lamp 26 when the outer panel 18 and the lamp 26 are mounted to the body structure 30. Fit and finish requirements can necessitate that the gaps G fall within a set rangegaps outside the set range could be aesthetically unacceptable.

(22) Build tolerances and other variables can influence a size of the gaps G. For example, although the outer panel 18 can be fixture set when mounting to the body structure 30, the precise positioning of the outer panel 18 can vary by, say, 3.0 millimeters. If the lamp 26 is not positioned to accommodate for these variations, the variations can cause the gaps G to fall outside the set range.

(23) A size of the gaps G could be controlled, in part, by mounting of at least a portion of the lamp 26 to the outer panel 18 such that the lamp 26 is located directly from the outer panel 18. This, however, could prevent a user from swapping the outer panel 18 for another while keeping the lamp 26 secured to the body structure 30.

(24) Referring to FIGS. 5-7, an alignment fixture 38 is utilized when securing the lamp 26 to a fixed structure of the vehicle 10 (FIG. 1). The alignment fixture 38 helps to position the lamp 26 relative to the outer panel 18. The alignment fixture 38 helps position the lamp 26 without requiring the lamp 26 to directly mount to the outer panel 18.

(25) Generally, the alignment fixture 38 positions a mounting bracket 42 relative to the outer panel 18 in a mounting position. The mounting bracket 42 is then secured to the body structure 30 such that the mounting bracket 42 becomes a fixed structure of the vehicle 10. The lamp 26 mounts to the mounting bracket 42. When the lamp 26 mounts to the mounting bracket 42, the lamp 26 is positioned relative to the outer panel 18 such that the gaps G are within the set range. The alignment fixture 38 is utilized when securing the mounting bracket 42 in the mounting position, but is removed from the vehicle 10 prior to securing the lamp 26 to the body structure 30.

(26) To secure the lamp 26, the alignment fixture 38 is moved from a position shown in FIG. 5 where the alignment fixture 38 is disengaged from the mounting bracket 42, to a position shown in FIG. 6 where the alignment fixture 38 is engaged with the mounting bracket 42.

(27) Engagement between the mounting bracket 42 and the alignment fixture 38 comprises pins 46 of the alignment fixture 38 being positioned within corresponding apertures 50A, 50B of the mounting bracket 42.

(28) The aperture 50A has a circular profile whereas the aperture 50B has a profile that is extended longitudinally along a Z-Axis. These profiles provide the locating functionality when the pins 46 are received within the respective apertures 50A, 54B. The aperture 50A locates the alignment fixture 38 and the mounting bracket 42 along the Z-axis and along a Y-axis. The aperture 50B locates the alignment fixture 38 relative to the mounting bracket 42 along the Y-axis.

(29) Although the pins 46 extend from the alignment fixture 38 and the apertures 50A, 50B are within the mounting bracket 42, these components could be reversed such that the pins 46 extend from the mounting bracket 42 and the apertures 50A, 50B are within the alignment fixture 38.

(30) As shown in FIG. 6, the alignment fixture 38 engaged with the mounting bracket 42 is then moved toward locating apertures 54A and 54B within the outer panel 18. After sufficient movement, an aperture 54A in the outer panel 18 receives a pin 58 of the alignment fixture 38, and an aperture 54B in the outer panel 18 receives another pin 58 of the alignment fixture 38. When the pins 58 are received within the apertures 54A, 54B, the alignment fixture 38 is engaged with the outer panel 18.

(31) The aperture 54A has a circular profile whereas the aperture 54B has a profile that is extended longitudinally along a Z-Axis. These profiles provide a locating functionality when the pins 58 are received within the respective apertures 54A, 54B. The aperture 54A locates the alignment fixture 38 relative to the outer panel 18 along the Z-axis and along the Y-axis. The aperture 54B locates the alignment fixture 38 relative to the outer panel 18 along the Y-axis. Because the alignment fixture 38 is engaging the mounting bracket 42, locating the alignment fixture 38 relative to the outer panel 18 locates the mounting bracket 42 relative to the outer panel 18.

(32) Although the pins 58 extends from the alignment fixture 38 and the apertures 54A, 54B are within the mounting bracket 42, these could be reversed such that the pins 58 extend from the mounting bracket 42 and the apertures 54A, 54B are within the alignment fixture 38.

(33) FIG. 8 shows the alignment fixture 38 engaged with both the mounting bracket 42 and the outer panel 18. When in this position, mechanical fasteners 62 are moved through access apertures 66 in the alignment fixture 38. The mechanical fasteners 62 are torqued down to seat the mechanical fasteners 62 and hold the mounting bracket 42 relative to the body structure 30. When secured, the mounting bracket 42 is part of a fixed structure of the vehicle 10.

(34) The alignment fixture 38 is then removed as shown in FIG. 9. After the alignment fixture 38 has been removed as shown in FIG. 10, the mounting bracket 42 and outer panel 18 remain positioned relative to one another since both are secured to the body structure 30.

(35) The lamp 26 is then moved toward the mounting bracket 42 as shown in FIG. 11 and secured to the mounting bracket 42 to hold the position of the lamp 26 relative to the body structure 30. When the lamp 26 is secured to the mounting bracket 42, as shown in FIG. 4, the gaps G meet fit and finish requirements.

(36) Notably, after securing the lamp 26 to the mounting bracket 42 as shown in FIG. 4, the outer panel 18 can be decoupled from the body structure 30 while the lamp 26 remains secured to the body structure 30 through the mounting bracket 42.

(37) When in the installed position, the lamp 26 is nested within an opening 70 of the outer panel 18 such that the outer panel 18 extends along an upwardly facing surface 74 of the lamp 26 and additionally along an outboard facing surface 78 of the lamp 26. The gaps G extend between the outer panel 18 and both the upwardly facing surface 74 and the outboard facing surface 78.

(38) A general vehicle lamp installation method 100 utilizing the techniques described above can begin at a step 104 where both a mounting bracket and an outer panel of a vehicle are engaged within an alignment fixture. The alignment fixture locates the mounting bracket relative to the outer panel in a mounting position. The outer panel is attached to a fixed structure of a vehicle.

(39) Next, at a step 108, the mounting bracket is secured to the body structure of the vehicle, which holds the position of the mounting bracket relative to the outer panel.

(40) The method 100 then, at a step 112, secures a lamp to the mounting bracket. Because the mounting bracket was positioned relative to the outer panel, gaps between the lamp and the outer panel can be reliably controlled. Because the lamp is secured to the mounting bracket, but not the outer panel, the outer panel can be removed as required without significantly disturbing the position of the lamp.

(41) The preceding description is exemplary rather than limiting in nature. Variations and modifications to the disclosed examples may become apparent to those skilled in the art that do not necessarily depart from the essence of this disclosure. Thus, the scope of legal protection given to this disclosure can only be determined by studying the following claims.
