Abstract
Description
- This application is a continuation of prior U.S. application Ser. No. 15/178,145 filed on Jun. 9, 2016, presently allowed. The entire disclosure of the above application is incorporated hereby by reference.
- The invention relates generally to a rear speaker mounting shelf for a motor vehicle.
- The statements in this section merely provide background information related to the present disclosure and may or may not constitute prior art.
- In common motor vehicle rear speaker mounting shelf structures, a single plate or multiple plates of steel material are joined typically by welding or fastening to outer frame structure of the vehicle, which are also commonly made of a steel material. Steel material is used for known speaker mounting shelf structures to provide structural strength to support features such as the loads imparted from rear seat belt retractors, seat back latches, deck lid hinges, speaker and woofer attachments and the like. Steel material similar to the material of the vehicle frame also allows welding of the shelf to vehicle frame connections.
- While material coatings such as a polymeric coating applied onto the steel structural members are known which are relied on to reduce noise, polymeric material coatings applied to known speaker mounting shelf structures are not relied on for structural strength or stiffness. This field can therefore benefit from improved rear speaker mounting shelf structure designs.
- According to several aspects, a motor vehicle hybrid shelf assembly includes a body formed of a metallic sheet. A shelf of the body defines a plane having at least one aperture created therein. The at least one aperture is at least partially surrounded by a peripheral flange created from a portion of the shelf extending away from the plane defined by the shelf. A reinforcement member of a polymeric material is integrally connected to the peripheral flange.
- In one aspect, the peripheral flange defines an L-shape having a first leg integrally connected to the body and oriented substantially parallel to the body, and a second leg angularly oriented with respect to the first leg.

- In another aspect, the body includes multiple second apertures each having a peripheral flange with a reinforcement member of a polymeric material integrally connected to each peripheral flange, and a rib connected to the body between the at least one aperture and each of the second apertures.
- According to further aspects, a motor vehicle hybrid shelf assembly includes a body formed of a metallic sheet. A shelf of the body defines a plane having multiple apertures created therein. Each of the apertures is at least partially surrounded by a peripheral flange created from a portion of the shelf extending away from the plane defined by the shelf. A first leg of the peripheral flange of each of the apertures is integrally connected to the shelf and is angularly oriented with respect to the shelf. A second leg of the peripheral flange of each of the apertures is angularly oriented with respect to the first leg. A reinforcement member of a polymeric material is integrally connected to at least the second leg of the peripheral flange of each of the apertures.
- In another aspect, the reinforcement member is also integrally connected to the first leg of the peripheral flange of each of the apertures.
- In another aspect, multiple ribs are formed of the polymeric material of the reinforcement member. The ribs directly contact and extend away from a surface of the body and act to stiffen the body.

Thehybrid shelf assembly 10 includes amain body 22 made of a metal including aluminum or steel. Thebody 22 can be formed for example by stamping and includes multiple integral reinforcing structures such as afront flange 24, arear flange 26, multiple raisedribs 28, and the like. To facilitate fixing thefirst side portion 14 and thesecond side portion 18 directly to theframe 12 which is commonly a ferrous metal material such as steel, thefirst side portion 14 and thesecond side portion 18 can be fixed by welding, fastening, or riveting. According to several aspects thefirst side portion 14 and thesecond side portion 18 can also be formed of a metal material such as steel or aluminum. - The
body 22 supports multiple components such as afirst speaker 30, asecond speaker 32, awoofer 34, and may also support other items (not shown) such as but not limited to seat belt retraction systems, wiring harnesses, tubing, ventilation components or ducting, and the like. One ormore reel housings 36 can be fixed to thefront flange 24, which are used to retract and store seat belts such as a firstrear seat belt 38, a secondrear seat belt 40, and a thirdrear seat belt 42. Thefront flange 24 and thebody 22 are therefore designed to incorporate the stress and loading induced by the various seat belts, as well as the components supported by thebody 22. Therear flange 26 can also be connected to arear cowling 46 at a junction with a rear window of the vehicle (not shown). In addition of the use of a light weight metal such as aluminum to minimize weight of thebody 22,multiple reinforcement members 48 of a polymeric material are integrally connected to thebody 22 at various locations, such as where loading and vibration is induced by the weight of the speakers. According to several aspects, a material of thereinforcement members 48 is adapted to be applied in an over-molding process and defines a glass fiber reinforced material. - Referring to
FIG. 2 and again toFIG. 1 , thehybrid shelf assembly 10 includes multiple apertures, with each aperture positioned to locate one of the speakers (shown and described in reference toFIG. 1 ). For example afirst aperture 50 is for locating thefirst speaker 30, asecond aperture 52 for locating thesecond speaker 32, and athird aperture 54 for locating thewoofer 34. Each of thefirst aperture 50, thesecond aperture 52 and thethird aperture 54 can be reinforced by the addition of a raised peripheral flange created in thebody 22, such as a first raisedperipheral flange 56, which reinforces thefirst aperture 50. In addition, portions of thereinforcement members 48 are located at the perimeter of multiple ones of the body apertures, including afirst reinforcement member 58 integrally connected to the first raisedperipheral flange 56, and asecond reinforcement member 60 integrally connected to a second raisedperipheral flange 62 adjacent thesecond aperture 52. Athird reinforcement member 64 is integrally connected to a peripheral flange adjacent to thethird aperture 54. - With continuing reference to
FIG. 2 and again toFIG. 1 , in order to provide additional structural reinforcement for thebody 22, thereinforcement members 48 can further include connectingmembers 66, which for example integrally connect thefirst reinforcement member 58 to thesecond reinforcement member 60. The connectingmembers 66 also provide an added benefit of allowing thefirst reinforcement member 58 and thesecond reinforcement member 60 to be simultaneously co-molded in a single injection molding “shot” of polymeric material, which reduces molding injection time, and reduces mold cost by reducing the quantity of molding gates required. The connectingmembers 66 can themselves be integrally connected using one or more joiningmembers 68, which can be oriented at any angle with respect to the connectingmembers 66, but are preferably oriented substantially perpendicular to the connectingmembers 66. The joiningmembers 68 are also integrally connected to thebody 22, and are created during the same injection molding shot which forms the connectingmembers 66 and thereinforcement members 48. - Additional polymeric material reinforcement can be provided during the same molding shot to the
front flange 24, using second joiningmembers 70, which can be integrally connected to one or more of the connectingmembers 66. Additional apertures, such as for example anaperture 72, can be reinforced with the same polymeric material of thereinforcement members 48, but molded via a separate injection molding gate and a separate molding shot, and therefore providing aseparate reinforcement member 74 about the perimeter of theaperture 72. Where structural features such as abeam 76 or a tube are incorporated into thebody 22, separate polymeric material reinforcement can also be provided, such as by areinforcement member 77. According to several aspects, thebeam 76 is positioned proximate to a vehicle rear facing portion of thebody 22. - Referring to
FIG. 3 and again toFIGS. 1 through 2 , according to several aspects, the peripheral flange proximate one or more of the apertures can define an L-shape. For example, theperipheral flange 56 of thefirst aperture 50 defines an L-shape having afirst leg 78 integrally connected to thebody 22 and oriented substantially parallel to thebody 22, and asecond leg 80 angularly oriented with respect to thefirst leg 78. According to several aspects, thereinforcement member 58 entirely covers thesecond leg 80. According to further aspects, thereinforcement member 58 further covers a portion of thefirst leg 78. According to several aspects, any of the peripheral flanges can also define an S-shape, such as theperipheral flange 62 of thesecond aperture 52, which is described in greater detail in reference toFIG. 4 . - A first shelf S1 of the
body 22 defines a first plane “A” having thefirst aperture 50 created therein. A second shelf S2 of thebody 22 defines a second plane “B” having thesecond aperture 52 created therein. As previously noted, each of thefirst aperture 50 and thesecond aperture 52 is at least partially surrounded by either theperipheral flange 56, or theperipheral flange 62 created from a portion of the shelf S1, S2 extending away from the plane “A” or “B” defined by the shelf. It is noted the first shelf S1 and the second shelf S2 are provided as exemplary aspects of thebody 22, and that any planar portion of thebody 22 can include an aperture, a channel, or another reinforcement feature having a polymeric material reinforcement member created about a perimeter of a peripheral flange of the aperture, or a reinforcement member extending away from the planar portion. - Referring now to
FIG. 4 and again toFIG. 3 , according to several aspects and as noted above, theperipheral flange 62 defines an S-shape. Theperipheral flange 62 includes afirst leg 82 integrally connected to thebody 22 and angularly oriented with respect to thebody 22, asecond leg 84 angularly oriented with respect to thefirst leg 82, and athird leg 86 angularly oriented with respect to thesecond leg 84. According to further aspects, thereinforcement member 60 includes afirst portion 88 entirely covering thethird leg 86. According to additional aspects, thereinforcement member 60 further includes asecond portion 90 that covers a portion of thesecond leg 84. According to further aspects, thereinforcement members peripheral flanges - Referring to
FIG. 5 , and again toFIGS. 1 through 2 , as previously noted thebody 22 is predominantly made of an aluminum material and theopposed side portions Apertures 92 are provided for application of fasteners (not shown) used to join the first and thesecond side portions body 22. The first and thesecond side portions second side portions steel material frame 12 of the vehicle, and to minimize the interaction of dissimilar metals at these junctions. The first and thesecond side portions reinforcement members 94, as well as thereinforcement member 74 provided about the perimeter of theaperture 72 previously described in reference toFIG. 2 . - Referring to
FIG. 6 and again toFIGS. 1 through 5 , reinforcements members such as areinforcement member 96 can be used to span externally facing angled surfaces such as a substantiallyplanar surface 98 and asurface 100 which is oriented substantially perpendicular to surface 98. To assist in retaining the reinforcement members in integral contact with thebody 22, each of the reinforcement members of the present disclosure can further include one ormore interlocks 102, shown and described in greater detail in reference toFIG. 7 . Reinforcement members such as areinforcement member 104 can also be used to span internally facing angled surfaces such as a substantiallyplanar surface 106 and asurface 108 which is oriented substantially perpendicular tosurface 106. Additional reinforcement members such as areinforcement member 110 can be used to integrally connect proximate reinforcement members, such as to connect thefirst reinforcement member 58 integrally connected to the first raisedperipheral flange 56 to areinforcement member 112 created at a raised perimeter of anaperture 114. Each reinforcement member directly contacts and extends away from a surface of thebody 22 and stiffens thebody 22. - Referring to
FIG. 7 and again toFIG. 6 , multiple interlocks such as therepresentative interlock 102 shown are integral portions of the multiple reinforcement members such as thereinforcement member 96 shown. Each interlock extends through anaperture 114 created in thebody 22 or through a similar aperture create in one of the first or thesecond side portions opposite surface 116 of the panel they extend through, such as thebody 22, or can have a bulbous-shapedbutton 118, which overlaps thesurface 116 of the panel to thereby create a positive lock to prevent pullout of the interlock. A height “H” of any reinforcement member, such as thereinforcement member 96, can vary as necessary to provide additional localized stiffness to thebody 22, or as necessary to span between adjacent reinforcement members. - Referring to
FIG. 8 and again toFIG. 1 , one or more reinforcement channels such as aU-shaped channel 120 can be created in thebody 22, for example between thefront flange 24 and aproximate flange 122. Additional polymeric material reinforcement members which define an X-shape, such asX-shaped reinforcement members front flange 24 and theflange 122. Additional X-shaped reinforcement members, such asreinforcement members 128 can be either smaller or larger than theX-shaped reinforcement members body 22, particularly at areas such as the loading positions of the seat belt reel housings 36 (shown inFIG. 1 ). - According to several aspects, a motor vehicle
hybrid shelf assembly 10 includes abody 22 formed of a metallic sheet. A shelf S1 of thebody 22 defines a plane “A” having at least oneaperture 50 created therein. The at least oneaperture 50 is at least partially surrounded by aperipheral flange 56 created from a portion of the shelf extending away from the plane “A” defined by the shelf. Areinforcement member 58 of a polymeric material is integrally connected to theperipheral flange 56. - It is noted that items identified herein as being a stamping of a metal material can also be provided as cast, forged, or extruded structures. A motor vehicle
hybrid shelf assembly 10 of the present disclosure offers several advantages, including the ability to tailor a structural performance of different model vehicle shelf assemblies for different structural loading requirements, different NVH (i.e., noise, vibration, harshness) requirements, and for different vehicle options that may impact the shelf assemblies. The use of the polymeric material reinforcement members as well as the use of aluminum material for substantial portions of the body provide for weight savings compared to an entirely steel shelf assembly. - The description of the invention is merely exemplary in nature and variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
