DETAILED DESCRIPTION
Vehicles according to the present specification include a cowl structure that is located between a front windshield and an engine room of the vehicles. The cowl structure includes a cowl louver structure that is supported by a cowl panel, providing a support structure for the cowl louver structure. The cowl louver structure includes a windshield receiving recess that extends in a vehicle lateral direction and that is sized and arranged to receive a bottom edge of the front windshield therein. A cowl louver clip assembly is provided that can separately attach to the cowl louver structure along the windshield receiving recess to provide an engaging pressure against the front windshield to support the cowl louver structure with the bottom edge of the front windshield within the windshield receiving recess.
As used herein, the term “vehicle longitudinal direction” refers to the forward-rearward direction of the vehicle (i.e., in the +/− vehicle X-direction depicted in FIG. 1). The term “vehicle lateral direction” refers to the cross-vehicle direction (i.e., in the +/− vehicle Y-direction depicted in FIG. 1), and is transverse to the vehicle longitudinal direction. The term “vehicle vertical direction” refers to the upward-downward direction of the vehicle (i.e., in the +/− vehicle Z-direction depicted in FIG. 1). Further, the terms “inboard” and “outboard” are used to describe the relative positioning of various components of the vehicle. Referring to FIG. 1, the term “outboard” as used herein refers to the relative location of a component in direction 12 with respect to a vehicle centerline 10. The term “inboard” as used herein refers to the relative location of a component in direction 14 with respect to the vehicle centerline 10. Because the vehicle structures may be generally symmetrical about the vehicle centerline 10, the direction to which use of terms “inboard” and “outboard” refer may be mirrored about the vehicle centerline 10 when evaluating components positioned along opposite sides of the vehicle 100.
Referring initially to FIG. 1, a vehicle 100 is depicted. The vehicle 100 includes a body 110 onto which a vehicle drivetrain is coupled. The vehicle 100 also includes a cabin 108 that is integral with the body 110 and an engine bay 112 where a power unit (e.g., engine and transmission) is located. The cabin 108 generally defines a passenger cabin of the vehicle 100. A front windshield 114 is provided at a front of the passenger cabin 108. The front windshield 114 may be framed by a cowl structure 116, a pair of front or A pillars 118 and 120 and a roof header of a roof. A cowl louver structure 122 is used to receive a bottom edge of the front windshield 114. The cowl structure 116 can function as a lower end support of the front windshield 114 at the rear end of the engine bay 112, as will be described in greater detail below.
Motor vehicles that incorporate elements according to the present disclosure may include a variety of construction methodologies that are conventionally known, including the unibody construction methodology as well as a body-on-frame construction methodology. Additionally, the Figures may only show a portion or side of the vehicle. Descriptions of the other side of the vehicle may be omitted because both sides and other portions of the vehicle may be substantially the same.
Referring to FIG. 2, the cowl louver structure 122 and front windshield 114 are shown in isolation. The cowl louver structure 122 may be provided above a cowl panel in an area between a vehicle hood 126 and the front windshield 114 (FIG. 1) to cover an upward opening in the cowl panel. The cowl louver structure 122 may generally extend in the vehicle lateral direction and be provided with air inlets 128 that allow outside air from the environment to be drawn to the cowl structure 116. This air can be used, for example, for the air conditioning or sent directly to the vehicle interior (e.g., via ducts). The cowl louver structure 122 includes a louver body 130 including the air inlets 128. An air guide structure 132 may be provided that extends laterally along a rear side of the air inlets 128 and at least partially overhangs the air inlets 128 to direct air from the environment into the air inlets 128, particularly during movement of the vehicle.
The cowl louver structure 122 further includes a windshield engagement structure 134 that extends laterally along a rear edge 136 of the louver body 130. As can be seen, the windshield engagement structure 134 is shaped and arranged to receive a bottom edge 138 of the front windshield 114 to engage the bottom edge 138 of the front windshield 114. A plurality of cowl louver clip assemblies 140 are provided along the windshield engagement structure 134. The cowl louver clip assemblies 140 may be located to an interior side 142 of the front windshield 114 and spaced-apart from each other in the vehicle lateral direction. The cowl louver clip assemblies 140 may provide discrete, spaced apart support areas that are used to engage the front windshield 114 in the illustrated position.
FIGS. 3-5 illustrate the cowl louver clip assembly 140 in isolation. The cowl louver clip assembly 140 includes a protrusion receiving body 144 and a protector member 146 extending along the protrusion receiving body 144. The protrusion receiving body may be made of any suitable material, such as a molded plastic material. The protrusion receiving body 144 includes a windshield receiving end 148, a windshield engaging top 150, a protrusion receiving end 152 opposite the windshield engaging end 150 and a wall engaging bottom 154 opposite the windshield engaging top 150. Side walls 156 and 158 extend between the windshield receiving end 148, the windshield engaging top 150, the protrusion receiving end 152 and the wall engaging bottom 154. The windshield receiving end 148 includes an angled guide surface 160 that extends at an oblique angle to the windshield engaging top 150 and the wall engaging bottom 154. For example, in some embodiments, the angle θ between the guide surface 160 and the wall engaging bottom 154 may be less than 90 degrees, such as less than about 75 degrees, such as less than about 60 degrees, such as 45 degrees or less. Such an oblique arrangement for the guide surface 160 can provide a wide lead-in angle for inserting the front windshield 114, as will be described below.
The protrusion receiving body 144 includes an extension portion 166 that extends outwardly beyond the windshield engaging top 150, providing a somewhat open top portion 168 at the extension portion 166. Engaging arms 170 and 172 are provided that extend outwardly from an inner surface 174 of the wall engaging bottom 154. In the illustrated embodiment, two engaging arms 170 and 172 are provided that extend upwardly from the surface 174 at angles α1 and α2, respectively (FIG. 5). In the illustrated embodiment, α1 and α2 may be substantially the same. In other embodiments, α1 and α2 may be different. The angles α1 and α2 may facilitate some resilient flexibility for the engaging arms 170 and 172 to rotate in the directions of arrows 176 and 178, away from each other to accommodate variances in installation. While two engaging arms 170 and 172 are illustrated, there may be one or more than two engaging arms, depending, for example, on the particular installation. In some embodiments, one or more of the engaging arms may be substantially perpendicular to the inner surface 174.
Referring particularly to FIG. 5, extending outwardly from inner surfaces 180 and 182 of the side walls 156 and 158, respectively, are side guide projections 184 and 186. The side guide projections 184 and 186 extend outwardly substantially perpendicularly from the inner surfaces 180 and 182 to ends 188 and 190. Extending outwardly from an inner surface 192 of the windshield engaging top 150 are top guide projections 194 and 195. The top guide projections 194 and 195 extend outwardly substantially perpendicularly from the inner surface 192 to ends 196 and 197. The engaging arms 170 and 172, side guide projections and top guide projection 194 form a volume 200 to receive a support protrusion 224 (FIG. 6A), as will be described below.
Referring again to FIGS. 3-5, the cowl louver clip assembly 140 further includes the protector member 146. The protector member 146 is formed as a raised strip of resiliently compressible material (e.g., plastic, foam, rubber, etc.) that extends over the windshield receiving end 148, the windshield engaging top 150 and the wall engaging bottom 154. In some embodiments, the protector member 146 may extend over substantially all the length or perimeter of the windshield receiving end 148, the windshield engaging top 150 and the wall engaging bottom 154. In some embodiments, the protector member 146 may extend over only a portion of the length of the wall engaging bottom 154 (FIG. 7). In the illustrated embodiment, the protector member 146 extends over only a portion of the width of the protrusion receiving body 144 at each of the windshield receiving end 148, the windshield engaging top 150 and the wall engaging bottom 154. In some embodiments, the protector member 146 may extend over no more than about 50 percent of the width (e.g., no more than about 35 percent of the width, such as no more than about 25 percent of the width) of the protrusion receiving body 144 at the windshield receiving end 148, the windshield engaging top 150 and the wall engaging bottom 154. In other embodiments, the protector member 146 may extend over the entire width of the protrusion receiving body 144 at the windshield receiving end 148, the windshield engaging top 150 and the wall engaging bottom 154. Further, while the protector member 146 is shown as having a substantially constant width at each of the windshield receiving end 148, the windshield engaging top 150 and the wall engaging bottom 154, the protector member 146 may have varying widths. The protector member 146 may be a single material or combination of materials, such as foam or rubber laminated or coated with a plastic film.
FIGS. 6A and 6B illustrate a process of installation of the cowl louver clip assembly 140 to the cowl louver structure 122 in preparation for installation of the front windshield 114 (FIG. 2). The cowl louver structure 122 includes the windshield engagement structure 134 that includes an outer support wall 208 and a windshield receiving recess 210 adjacent the outer support wall 208. A seal member 212 may extend along an outer edge 214 of the outer support wall 208 that can seal against the exterior side 215 (FIG. 7) of the front windshield 114.
Referring particularly to FIG. 6A, a support structure 220 extends outwardly from a floor 222 of the windshield receiving recess 210. The support structure 220 may include a support protrusion 224 and a base structure 226. In the illustrated embodiment, both the base structure 226 and the support protrusion 224 extend directly from the floor 222 of the windshield receiving recess 210 with the support protrusion 224 adjacent the base structure 226 in the vehicle vertical direction. Referring also to FIG. 6B, the base structure 226 is also wider than the support protrusion 224 in the vehicle lateral direction providing an overhang 228 and 230 that can receive the extension portion 166 of the protrusion receiving body 144 and provide resistance against turning of the cowl louver clip assembly 140 due to weight of the front windshield 114 (FIG. 7) with the support protrusion 224 received within the volume 200 (FIG. 5).
Referring now to FIG. 7, a more detailed section view of the cowl louver clip assembly 140 connected to the support structure 220 is illustrated. As can be seen, the cowl louver clip assembly 140 is connected to the support structure 220 by inserting the support protrusion 224 into the volume 200 of the protrusion receiving body 144. In instances where the height or thickness of the support protrusion 224 is more than the height of the volume 200, the engaging arms 170 and 172 may have flexibility to bend and increase the volume 200 for receiving the support protrusion 224. The engaging arms 170 and 172 may also be resilient to bias the engaging arms 170 and 172 against the support protrusion 224 to provide a friction engagement therebetween.
Inserting the support protrusion 224 into the volume 200 of the protrusion receiving body 144 can cause the wall engaging bottom 154 to engage and slide along an inner support wall 236. As can be seen, a free end 238 of the inner support wall 236 is spaced further from the support protrusion 224 than a cantilevered end 240 opposite the free end 238. Such an arrangement can provide a relatively wide opening 242 through which the wall engaging bottom 154 of the protrusion receiving body 144 can be received. Further, the opening 242 narrows from the free end 238 such that the wall engaging bottom 154 eventually engages the inner support wall 236, which can tend to increase the friction engagement between the support protrusion 224 and the engaging arms 170 and 172.
FIG. 7 illustrates the cowl louver clip assembly 140 being used to engage the bottom edge 138 of the front windshield 114. The front windshield 114 may be sandwiched within a gap 207 between the outer support wall 208 of the cowl louver structure 122 and the windshield engaging top 150 of the cowl louver clip assembly 140. The seal member 212 and the protector member 146 may be located to directly engage opposite sides 215 and 142, respectively. Any suitable materials may also be used to adhere to the front windshield 114, such as tape, adhesives, etc. The cowl louver clip assembly 140 can allow for adjustment of the windshield receiving recess 210, between the outer support wall 208 and the support protrusion 224. Tuning of the cowl louver clip assembly 140 can be accomplished by changing dimensions of the guide projections 184 and 186 (FIG. 5), top guide projections 194 and 195 and engaging arms 170 and 172. The cowl louver clip assembly 140 can also facilitate insertion of the front windshield 114 between the cowl louver clip assembly 140 and the outer support wall 208. For example, the cowl louver clip assembly 140 can provide a relatively large lead-in angle θL (e.g., greater than about 40 degrees, such as greater than about 45 degrees) measured between the front windshield 114 and the windshield receiving end 148. The cowl louver clip assembly 140 can also provide a relatively large lead-in height HL, which is the height of the windshield receiving end 148 (e.g., greater than about 11 mm, such as greater than about 15 mm) and a relatively large lead-in length LL, which is the length of the windshield receiving end 148 (e.g., greater than about 0.5 mm, such as greater than about 5 mm, such as greater than about 9 mm).
The above-described cowl louver clip assemblies are provided that can separately attach to the cowl louver structures along the windshield receiving recesses at multiple locations to provide an engaging pressure against the front windshields to engage bottom edges of the front windshields within the windshield receiving recesses. The cowl louver clip assemblies can improve the installation effort of installing front windshields by increasing a lead-in angle for the front windshields, increasing dimensions of a lead-in opening that receives the front windshield and increasing a lead-in length to more easily catch and guide the front windshields during assembly. Further the cowl louver clip assemblies can be tuned for a desired fit before or even after a start of production of a particular vehicle.
