Abstract
A motor vehicle hybrid shelf assembly includes a body defining a member of a motor vehicle frame, the body including an aperture having edges. A module is positioned at the aperture, the module defining a load bearing portion of the body replacing a load bearing capability of a body portion removed to define the aperture. Multiple connecting arms extend from the module and beyond the edges of the aperture to support the module on the body, including a first, second, third and fourth connecting arm. Each of the connecting arms is connected to the body using a fastener. Multiple connecting members integrally connect a first reinforcement member surrounding the aperture to a second reinforcement member. The multiple connecting members allow the first and second reinforcement members to be simultaneously co-molded in a single injection molding shot of a polymeric material.

- With reference to
FIG. 1 , a motor vehicle hybrid shelf assembly is generally indicated byreference number 10. According to several aspects, thehybrid shelf assembly 10 is a structural member of an exemplarymotor vehicle frame 12 used in a motor vehicle (not shown). Thehybrid shelf assembly 10 is connected for example by welding, fastening or riveting at a first end orside portion 14 to afirst member 16 of theframe 12 and at an opposed second end orside portion 18 to asecond member 20 of theframe 12. Thehybrid shelf assembly 10 includes amain body 22 defining a formed plate made of a metal including aluminum or steel. Thebody 22 is formed for example by a stamping and a cutting process 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 and asecond speaker 32. Acomponent relief aperture 34 is positioned between thefirst speaker 30 and thesecond speaker 32, which will be described in greater detail in reference toFIG. 2 . Thebody 22 may also support other items 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 third rear 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 is connected to arear cowling 46 at a junction with a rear window of the vehicle (not shown) such that the body is positioned proximate to the rear window of a motor vehicle. In addition to 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 applied in an over-molding process defines a glass fiber reinforced material. - Referring to
FIG. 2 and again toFIG. 1 , thehybrid shelf assembly 10 provides thecomponent relief aperture 34 positioned between afirst aperture 50 positioned to receive the first speaker 30 (shown and described in reference toFIG. 1 ) and asecond aperture 52 positioned to receive thesecond speaker 32. Acomponent receiving module 54 of a molded polymeric material is positioned between thefirst aperture 50 and thesecond aperture 52. Thecomponent receiving module 54 can be used to house a component such as an electrical component (not shown), which can include items such as a computer used for example for autonomous driving control. To reduce a total weight of thehybrid shelf assembly 10, thecomponent relief aperture 34 is sized larger than thecomponent receiving module 54, except where connecting arms of thecomponent receiving module 54 extend beyond the edges of thecomponent relief aperture 34. The connecting arms include a first connectingarm 56, a second connectingarm 58, a third connectingarm 60 and a fourth connectingarm 62. Thecomponent receiving module 54 is fixed to thebody 22 for example using fasteners 64 individually extending through each of the connecting arms and thebody 22. - With continuing reference to
FIG. 2 and again toFIG. 1 , in order to provide structural reinforcement for thebody 22 where thecomponent relief aperture 34 is located, the structural loads normally carried by thebody 22 are transferred through and therefore designed to be carried by thecomponent receiving module 54. Because thecomponent receiving module 54 will necessarily be provided, a net weight savings is achieved by eliminating the portion of thebody 22 at thecomponent relief aperture 34 and carrying the structural load of thebody 22 where thecomponent relief aperture 34 is created at least in part via thecomponent receiving module 54. Thecomponent receiving module 54 therefore defines a load bearing member or portion of thehybrid shelf assembly 10 replacing a load bearing capability of the portion of thebody 22 removed to define thecomponent relief aperture 34. - Referring to
FIG. 3 and again toFIGS. 1 through 2 , according to several aspects, a motor vehiclehybrid shelf assembly 66 is modified from the motor vehiclehybrid shelf assembly 10, with common components identified using an apostrophe symbol. The motor vehiclehybrid shelf assembly 66 includes ashelf 68 located between thefirst speaker 30′ and thesecond speaker 32′ which includes multipleweight reduction apertures weight reduction apertures component relief aperture 34 shown and described in reference toFIG. 1 . - Referring to
FIG. 4 and again toFIGS. 1 through 3 , according to several aspects advantage can be taken of the multipleweight reduction apertures component receiving module 54. According to these aspects, the motor vehiclehybrid shelf assembly 66 provides for one or more molded-in-placecomponent receiving modules 78. Polymeric material is supplied in an injection mold via one or more connecting members 80, which for example integrally connect a first reinforcement member 82 surrounding theweight reduction aperture 72 to a second reinforcement member 84 surrounding theweight reduction aperture 76. The connecting members 80 also provide an added benefit of allowing thecomponent receiving modules 78, the first reinforcement member 82, and the second reinforcement member 84 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. - According to several aspects, the
component receiving module 78 defines a first half of an enclosure prior to the electrical component being installed, and prior to a separately molded cover (shown and described in reference toFIG. 6 ) being connected to thecomponent receiving module 78. According to further aspects, thecomponent receiving module 78 defines a rectangular shape, however, any desired geometric shape can be provided. Thecomponent receiving module 78 can include molded-in-place reinforcement members 86, and can further include molded-in-placefastener receiving members 88 which can be used when installing the cover. In addition to thecomponent receiving module 78, additional component receiving modules can also be co-molded at the same time, which can include a secondcomponent receiving module 90 and a thirdcomponent receiving module 92. Any or all of thecomponent receiving modules hybrid shelf assembly 66, and therefore provide structural reinforcement where weight reducing apertures are incorporated. - Referring to
FIG. 5 , and again toFIG. 4 , each of thefastener receiving members 88 includes a blind bore 94 which according to several aspects defines a threaded bore adapted to receive a threaded fastener used to fix a separately provided cover (shown and described in reference toFIG. 6 ) onto thecomponent receiving module 78. According to further aspects, the blind bore 94 can also be adapted for use as a snap-fit, self-threading, riveted, or similar mechanical connection. Thecomponent receiving module 78 further includes a first flange 96 and asecond flange 98 fixed to a first outer wall 99. The first flange 96 and thesecond flange 98 are adapted to releasably retain and mount the cover, and can rotatably receive a hinge member connected to the cover to allow the cover to rotate between open and closed positions. - Referring to
FIG. 6 and again toFIGS. 4 through 5 , thefastener receiving members 88 are co-molded during the molding process to a secondouter wall 100 of thecomponent receiving module 78. Opposed third and fourthouter walls outer wall 100. Each of the walls is integrally co-molded and therefore fixed to abase member 106 which defines a substantiallyplanar surface 108. A portion of anexemplary cover 110 which can also be made of a polymeric or a composite material is independently provided for mechanical attachment to thecomponent receiving module 78 is shown. Thecomponent receiving module 78 defines a first half or portion of a component receiving member and thecover 110 defines a second half or portion of the component receiving member when mechanically attached to thecomponent receiving module 78. - Referring to
