The embodiments, examples and alternatives of the preceding paragraphs, the claims, or the following description and drawings, including any of their various aspects or respective individual features, may be taken independently or in any combination. Features described in connection with one embodiment are applicable to all embodiments, unless such features are incompatible.
The various features and advantages of this disclosure will become apparent to those skilled in the art from the following detailed description. The drawings that accompany the detailed description can be briefly described as follows.
This disclosure details vehicle assemblies that are made up of a plurality of loose layered build components. One or more of the loose layered build components may include locating features for locating and supporting the component relative to other components of the assembly while still permitting movement of the component or one of the other components in at least one direction during the assembly process. These and other features of this disclosure are described in greater detail below.
Although a specific component relationship is illustrated in the figures of this disclosure, the illustrations are not intended to limit this disclosure. The placement and orientation of the various components of the vehicle 10 are shown schematically and could vary within the scope of this disclosure. In addition, the various figures accompanying this disclosure are not necessarily to scale, and some features may be exaggerated or minimized to emphasize certain details of a particular component.
The vehicle 10 includes a front end 12. A front end assembly 14 of the front end 12, which may include multiple components including but not limited to a grille 16 and left and right headlamp assemblies 18, is mounted between left and right side fenders 20 of the vehicle 10. A hood 22 may be movably mounted laterally between the left and ride side fenders 20 and longitudinally between the front end assembly 14 and a cowl 24. The hood 22 may be opened to access an inner compartment (e.g., an engine compartment) of the vehicle 10.
The vehicle 10 is used herein to describe exemplary embodiments of vehicle assemblies, such as the front end assembly 14, which are made up of a plurality of loose layered build components. At least a portion of the loose layered build components of the front end assembly 14 may be “loosely” located, positioned, and supported relative to one another during the assembly process and prior to rigidly securing the components together and in place on the vehicle 10 in order to establish consistent margins and flushness between the components, thereby simplifying the overall assembly process.
The vehicle 10 of
The teachings of this disclosure are also applicable to vehicles that exclude the AGS and rely primarily on the bolster 28 as the main structural component between the hydroform brackets 26. Thus, the teachings of this disclosure are not limited to the exact configuration shown in
Each headlamp assembly 18 may include a housing 32, a lens 34, and one or more lights (lamps) 36 for emitting light from the vehicle 10. The headlamp assemblies 18 may be positioned within openings 38 established by the front end structural components (e.g., the bolster 28 and/or the AGS housing 30). The headlamp assemblies 18 and/or the front end structural components may include certain locating and securing features that both support and restrict movement of the headlamp assemblies 18 in one or more directions during assembly. These features may include various slots, holes, surfaces within apertures, pins, straps, tabs, clips, notches, ridges, etc. These features allow the headlamp assemblies 18 to be initially supported in position relative to the fenders 20, the bolster 28, and/or the AGS housing 30 while allowing for some movement in order to align the headlamp assemblies 18 with other components, such as the grille 16, during subsequent assembly steps. In an embodiment, the headlamp assemblies 18 may be supported relative to the front end structural components of the front end assembly 14 such that movement is largely restricted in the X-axis direction but slight movement is permitted in the Y-axis and Z-axis directions. Other configurations in terms of the movement that is permitted or limited are also contemplated within the scope of this disclosure.
The grille 16 may be secured in place relative to the other components of the front end assembly 14 after positioning the headlamp assemblies 18 within the openings 38. For example, the loosely supported headlamp assemblies 18 may be engaged by the grille 16 such that movement of the grille 16 relative to the headlamp assemblies 18 is restricted (and vice versa). The grille 16 and headlamp assemblies 18 may be loosely joined relative to one another such that the subassembly is moveable relative to at least one of the front end structural components. The grille 16 may therefore act as a fixture for properly aligning the headlamp assemblies 18 relative to the grille 16 during assembly, thereby establishing consistent margins and flushness therebetween. In other embodiments, the headlamp assemblies 18 act as fixtures for aligning the grille 16 and the headlamp assemblies 18 relative to one another.
Joining exterior skin components such as the grille 16 and the headlamp assemblies 18 together in the manner described above allows for the incorporation of certain features, including uncommon and/or previously-unobtainable styling improvements. Utilizing one exterior skin component as a locating fixture for one or more other exterior skin components provides for repeatable superior assembly and craftsmanship even when using uncommon styling improvements. By way of one example styling improvement, as best shown in
The grille 16 may include various features for locating, supporting, loosely connecting, and/or restricting movement of the grille 16 in one or more directions relative to other components of the front end assembly 14 (e.g., the headlamp assemblies 18 and/or the fenders 20). Exemplary locating and supporting features are described in greater detail below with reference to
Referring first to
The first locators 46 may engage corresponding first locators 52 of a front end structural component (here, the AGS housing 30) in order to loosely position the grille 16 relative to the front end structural component and for centering the grille 16 relative to the fenders in the Y-axis direction. Providing two of the first locators 46 on the grille 16 rather than a single centerline locator helps enable a more accurate positioning of the grille 16 within the front end assembly 14.
In an embodiment, as best illustrated in
The second locator 62 may be integrally molded features of the single piece body 40 and may protrude from the inner surface 42 of the single piece body 40 of the grille 16. In an embodiment, the second locators 62 protrude from the inner surface 42 at locations that are outboard of the first locators 46 of the grille 16. However, the second locators 62 could be disposed at any location of the inner surface 42 of the single piece body 40 of the grille 16
The second locator 62 may engage the corresponding locator 64 of the headlamp assembly 18 in order to align and secure the headlamp assembly 18 relative to a side of the grille 16. In an embodiment, the second locator 62 includes a four-way locating pin 66 and the corresponding locator 64 includes an opening (e.g., hole) 68 formed in a lug 70 that protrudes from the housing 32 of the headlamp assembly 18. The lug 70 may protrude from an upper surface 72 of the housing 32, in an embodiment.
The four-way locating pin 66 may include a star pin 74 having a tapered head 76. The tapered head 76 of the star pin 74 may be received within the opening 68 of the lug 70 in order to locate and support the grille 16 and the headlamp assembly 18 relative to one another. Once the tapered head 76 is received within the opening 68, the opening 68 of the lug 70 may restrict movement of the four-way locating pin 66 in each of the Y-axis and Z-axis directions (e.g., in both left and right directions along the Y-axis and in both up and down directions along the Z-axis).
The third locator 78 may be an integrally molded feature that protrudes from the inner surface 42 of the single piece body 40 of the grille 16. In an embodiment, the third locators 78 protrude from the inner surface 42 at locations that are outboard of the first locators 46 of the grille 16. However, the third locators 78 could be disposed at any location of the inner surface 42 of the single piece body 40 of the grille 16
The third locator 78 may engage the corresponding locator 80 of the headlamp assembly 18 in order to further align and secure the headlamp assembly 18 relative to a side of the grille 16. In an embodiment, the third locator 78 includes a two-way locating pin 82 and the corresponding locator 80 includes a slot 84 formed in a lug 86 that protrudes from the housing 32 of the headlamp assembly 18. The lug 86 is a separate lug from the lug 70 and may protrude from a lower surface 87 of the housing 32, in an embodiment.
The two-way locating pin 82 may include a star pin 88 having a tapered head 90. The tapered head 90 of the star pin 88 may be received at least partially through the slot 84 of the lug 86 in order to further locate and position the grille 16 and the headlamp assembly 18 relative to one another. Once the tapered head 90 is received within the slot 84, the slot 84 of the lug 86 may restrict left and right movement of the two-way locating pin 82 in the Y-axis direction while permitting a small amount of up and down movement in the Z-axis direction.
The fourth locator 92 may be integrally molded with and protrude from the inner surface 42 of the single piece body 40 of the grille 16. In an embodiment, the fourth locators 92 protrude from the inner surface 42 at locations that are outboard of the first locators 46, the second locators 62, and the third locators 78 of the grille 16. However, the fourth locators 92 could be disposed at any location of the inner surface 42 of the single piece body 40 of the grille 16
The fourth locator 92 may engage the corresponding locator 94 of the fender 20 in order to align and secure the grille 16 relative to the fender 20. In an embodiment, the fourth locator 92 is a two-stage locator that includes both a first locating pin 96 and a second locating pin 98, and the corresponding locator 94 includes a first slot 100 and a second slot 102 formed in a lug 104 that protrudes from the fender 20.
The first locating pin 96 of the fourth locator 92 may include an attachment clip 106 for tabbing the grille 16 to the fender 20. The attachment clip 106 may be received within the first slot 100 of the lug 104 of the fender 20 in order to control fore/aft movement of the grille 16 relative to the fender 20 along the X-axis.
The second locating pin 98 of the fourth locator 92 may include a star pin 108 having a tapered head 110. The tapered head 110 of the star pin 108 may be received at least partially through the second slot 102 of the lug 104 in order to further locate and position the grille 16 and the fender 20 relative to one another. Once the tapered head 110 is received within the second slot 102, the slot 102 of the lug 104 may restrict up and down movement of the second locating pin 98 in the Z-axis direction while permitting a small amount of left and right movement in the Y-axis direction.
The second locating pin 98 may extend beneath an extension 112 of the housing 32 of the headlamp assembly 18 such that the extension 112 rests on top of a portion of the second locating pin 98. The second locating pin 98 may therefore help control a Z-axis height of the headlamp assembly 18.
An additional locator 114 (e.g., a fifth locator) of the grille 16 may be used to further tab the grille 16 to the fender 20. The locator 114 may include an attachment clip 116 that may engage a slot 118 of an additional lug 120 of the fender 20 in order to restrict fore/aft movement of the grille 16 relative to the fender 20 along the X-axis.
The vehicle front end assemblies of this disclosure provide various locating features for locating and supporting loose layered build components of the assembly relative to one another. The locating features may locate the loose layered build components in each of the X-axis, Y-axis, and Z-axis directions, thereby controlling margins and flushness between the components and simplifying the overall assembly process.
