  • FIG. 3 shows a schematic view of an illustrative door system according to one or more embodiments herein.
  • the door system includes a door structure 300, outer core module 325, core module 400, window trim module 525 and trim panel 700.
  • the outer core module 325 is a frame structure that assembles to the door structure 300.
  • the window trim module 525 resembles the shape of a conventional upper window surround and assembles to the outer core module 325 and an upper portion of the core module 400.
  • the core module 400 assembles to the outer core module 325 and beneath the window trim module 525.
  • the trim panel 700 covers the core module 400 and completes the assembly of the door system.
  • the door system utilizes multi-material injection molding technology or robotic extrusion to integrate the various components.
  • Multi- material injection molding techniques allow two or more materials to be injection molded into a single or multiple cavity mold.
  • a two component or material process is commonly known as "2K” and a three material process is commonly known as "3K.”
  • Any suitable multi-material injection molding machine can be used, such as an Engel Victory Combi machine available from Engel Corp.
  • Additional in-mold processing techniques can also be used to enhance and/or facilitate the integration.
  • Illustrative in-mold processing techniques include, but are not limited to, multiple cavity tools, insert molding, movable core sections, and gas/water assist.
  • Robotic extrusion can also be used alone or in combination with any of these processing techniques. Robotic extrusion is particularly useful for applying the sealing members or other functional parts onto the already injection molded structure. With this system it is also possible to create hollow seal cross-sections if required.
  • door is intended to include any door.
  • door can refer to one or more passenger doors, whether hinged, sliding, lifting or with any other alternative opening/closing movement, lift gates, tail gates, and hatchbacks for any vehicle including cars, trucks, SUVs, trains, boats, airplanes, etc., whether for personal, recreational, military or commercial use:
  • Each of the substrates 300, 350, 400, 525, 700 can include one or more seals, plugs, and/or grommets.
  • the one or more seals, plugs, and grommets are injection molded on the substrate. Any one or more of the seals, plugs, and grommets can be directly molded on the substrate using two or three shot injection molding or robotic extrusion techniques.
  • the integrated seals, plugs, and grommets help prevent or eliminate water seepage, rattles, and vibration.
  • Such components also increase the acoustical performance of the part (i.e., provide sound insulation and the "closing sound" of the door) while compensating for differences in part tolerance and expansion while allowing some movement.
  • the trim panel 700 can further include one or more speaker covers 710, arm rests 720, door handle 730, window switches 740, door lock switches 750, side mirror controls 760, map pockets 770, and interior lights 780.
  • the trim panel 700 can provide a housing or substrate for other electrical, mechanical and sealing components to be attached or integrally molded, or insert molded thereto.
  • Illustrative components include, but are not limited to, air bags, air vents, switches; door handles; door locks; arm rests; map pockets; speaker covers or grilles; speakers; beltline seals; plugs; grommets; and core to frame seals.
  • Illustrative switches include window glass controls, window locks, outside mirror positioning controls, door locks, seat positioning controls, and stereo controls.
  • the trim panel 700 is injection molded from one or more materials, such as polyethylene, polypropylene and/or one or more other suitable materials described herein.
  • the arm rest 720, speaker cover 710, and map pocket 770 are injection molded on the trim panel 700 using multi-material or multi-shot injection molding techniques.
  • Each of the trim panel 700, arm rest 720, speaker cover 710, and map pocket 770 can be injection molded from the same or different one or more materials, including polyethylene, polypropylene and/or one or more other suitable materials described herein.
  • FIG. 4 shows a schematic plan view of one embodiment.
  • the door structure 300 can be fabricated from one or more separate panels.
  • the door structure 300 can include an outer skin 320 and an inner support 330 affixed to one another.
  • Each of the outer skin 320 and the inner support 330 can be injection molded from polyethylene or polypropylene and more preferably from a reinforced polypropylene.
  • each of the outer skin 320 and the inner support 330 can be injection molded, cast, extruded, molded or formed in an other way from one or more other suitable materials, such as the materials discussed herein.
  • each of the outer skin 320 and the inner support 330 can be stamped from aluminum or cold, rolled steel, assembled, and painted to meet the specifications of the OEM.
  • each of the outer skin 320 and the inner support 330 can be made from different types of steel (i.e., "tailored blanks"), welded together stamped and painted as desired.
  • the door structure 300 can be a single component or single panel. [0055] The door structure 300 has a first side or interior side 310 that faces the passenger compartment of the vehicle.
  • the interior side 310 of the door structure 300 can include a recessed cavity 315 that is sized and shaped to resemble the dimensions of the core module 400 such that when assembled, at least a portion of the core module 400 fits into the recessed cavity 315 of the door structure 300.
  • the core module 400 includes a perimeter seal (not shown in this view) that can be integrally formed therewith or attached separately. That seal creates a wet/dry barrier between the door structure 300 and the outer core module 325, helps to create a rattle free assembly, helps to reduce noise transmission, and helps compensate for thermal expansion, among other purposes and benefits.
  • the door structure 300 also has a second side or exterior side (not shown in this view) to which a side mirror 311 and external door handle (also not shown in this view) can be attached.
  • a side mirror 311 and external door handle also not shown in this view
  • the term “interior” refers to an orientation or direction facing toward the passenger compartment or inside of the vehicle
  • the term “exterior” refers to an orientation or direction facing away from the passenger compartment or inside of the vehicle.
  • the door structure 300 does not have a reinforcement structure or member located at or near the beltline 353. The absence of a reinforcement structure or member allows greater access to the window glass and other components that require assembly or repair.
  • the absence of such an obstruction at the beltline 353 makes the window glass assembly and disassembly very easy as explained in more detail below.
  • the absence of a reinforcement structure or member also reduces the overall weight of the door assembly, which leads to lighter vehicles and better gas mileage.
  • Figure 5A is a schematic view of one illustrative embodiment of the outer core module 325 in accordance with one or more embodiments described.
  • the outer core module 325 is a frame structure having an upper cavity 326 and a lower cavity 327.
  • the two cavities 326, 327 are separated by a support member 328 at about the beltline.
  • One or more seals can be easily integrated with the outer core module 325 providing increased noise reduction and improved water leakage resistance.
  • the outer core module 325 includes a glass run channel 350. At least a portion of the glass run channel 350 is disposed within the upper cavity 326 and at least a portion of the glass run channel 350 is disposed within the lower cavity 327 of the outer core module 325 as shown in Figure 5A. In one or more embodiments, the glass run channel 350 has an upper portion 351 disposed within the upper cavity 326 of the outer core module 325 and one or more lower portions 352 disposed within the lower cavity 327.
  • a first portion 352A of the glass run channel 350 is attached to the outer core module 325 below the belt line support 328 along the A pillar side of the outer core module 325, and a second portion 352B of the glass run channel 350 is attached below the belt line support 328 along the B pillar side of the outer core module 325.
  • at least one of the first and second portions 352A, 352B of the glass run channel 350 has enough length to contact the window glass when the window glass is in a lowered position. More preferably, both the first and second portions 352A, 352B of the glass run channel 350 have a sufficient length to contact the window glass when the window glass is in a lowered position.
  • the glass run channel 350 can be made from one or more separate sections or members that are fitted, welded, or otherwise attached together or kept in a fixed orientation relative to each other.
  • the glass run channel 350 is made from a single member.
  • the portions or sections 351, 352 A, and 352B can each be a separate piece or make up two or more pieces.
  • the glass run channel 350 has one or more cross sections (i.e., profiles) adapted to contact the window glass.
  • Illustrative profiles include "U" shaped, "L” shaped, and combinations thereof, either alone in combination with one or more lips, bulbs, or other sealing elements.
  • Figure 5B shows an enlarged, cross sectional view of the glass run channel 350 along lines A-A of Figure 5A.
  • the upper portion 351 of the glass run channel 350 has an open or "L" shaped profile 355 that can contact an outer edge of the window glass (not shown).
  • the window trim module 525 can have a matching profile (e.g., open or "L" shaped profile) that contacts an outer edge of the window glass so that the window glass is squeezed and sealed therebetween.
  • the A pillar side of the lower portion 352 A preferably has an "L" shaped profile 355 as does the B pillar side of the lower portion 352B.
  • the "L" shaped profile 355 contacts the outer (i.e., exterior) perimeter of the window glass.
  • the core module 400 can include a complementary shaped profile (i.e., open or "L shaped" profile) to contact the inner (i.e., interior) perimeter of the window glass, so that the matched profiles guide the window glass when assembled.
  • Such sealing system is similar to how the opposing profiles (i.e., seals) on the window trim module 325 and the upper portion 351 of the glass run channel 350 each work together to form a seal at the upper portion of the window glass.
  • Figure 6 is a schematic view of an illustrative core module 400 according to one or more embodiments herein.

  • the one or more bolsters 410, speaker boxes 425, window tracks 440, motor support 445, reinforcement section 450, belt line seal 465, and air distribution channels (not shown) can be integrally formed with the core module 400 using multi-material or multi-shot injection molding techniques. As such, assembly time is greatly reduced since the components are an integral part of the core module 400, and not a separate component requiring costly assembly.
  • the side bolsters 410 can be foamed members, such as foam blocks.
  • the side bolsters 410 can also be hollow structures.

  • the degree of integration described can dramatically reduce the cost and assembly complexity of the finished door. Assembly errors are also reduced if not eliminated. Functional testing costs after final assembly are also reduced or eliminated because a majority of the functionality can be tested prior to final assembly (i.e., pre-tested). Further, the use of plastic materials in the door assembly can provide lower overall weight, more part integration, improved noise insulation, greater design freedom and will enable cheaper design modifications (i.e., using replaceable inserts in an injection molding tool). [00117] Furthermore, the described placement of the reinforcement section and the seal systems allows for easy installation and assembly of the door system. In particular, the placement of the reinforcement section and the seal system provides easy access to the numerous components of the door including the window and window lift system. Such placement also allows the working components, most notably the window lift system, of the door to be functionality tested before final installation of the door to the vehicle. As such, valuable time and logistic concerns are greatly reduced.
  • the door system reduces the number of individual components (i.e., parts) and assembly steps required to produce the finished door.
  • the integration of the reinforcement section alone makes part assembly easier, reduces weight of the door and allows functionality testing of the various assembled components and parts. Further, the integrated parts can be positioned correctly and therefore, are less subjected to human error or omission.
