Description

[0001] Cross Reference to Related Applications

[0002] This application claims the benefit of priority under 35 U.S.C. § 119 from U.S. Provisional Application Serial No. 62 / 988,481, filed March 12, 2020, the contents of which are relied upon and incorporated herein by reference in their entirety. BACKGROUND

[0003] Vehicle interiors can include curved surfaces that contain displays and / or touch panels. Materials used to form such curved surfaces are typically limited to polymers that do not exhibit the durability, appearance, hand, and optical performance of glass. As such, curved glass substrates are desirable, especially when used as covers for displays and / or touch panels. Existing methods of forming curved glass substrates, such as hot forming, have drawbacks including high cost and optical distortion and / or surface marking during bending or forming. Thus, there is a need for vehicle interior systems that can contain curved glass substrates in a cost effective manner and without the problems typically associated with glass thermoforming processes. However, current cold forming methods have various drawbacks, including that the adhesive layer is subjected to both shear and tensile stresses in some cases. SUMMARY

[0004] The present disclosure provides, among other things, cold formed 3D products, such as curved glass substrates for surfaces of vehicle interiors, such as vehicle displays. In addition to this, the methods, systems, and apparatuses provided herein for forming such curved glass substrates provide various improvements. These improvements can include eliminating the need for a specific mold that is pre-manufactured to be adhered to the glass and become part of the final product, eliminating the need to dispense adhesive with a uniform thickness onto the mold, structural load is concentrated as shear forces, such that tensile forces and thus tensile stresses on the adhesive medium used to adhere to the curved glass substrate are reduced, improving the replaceability of the curved glass substrate and / or improving the usability by facilitating dynamic movement, such as flexure of a display, providing flexibility for visualization of the display when in use.

[0022] Reference characters that are repeated throughout the specification and drawings are intended to designate the same or similar features or elements of the present disclosure, even if the numbers differ by 100s between figures and figures. It will be appreciated by those skilled in the art that numerous other modifications and examples can be devised that fall within the scope and spirit of the principles of the present disclosure. DETAILED DESCRIPTION

[0023] Reference will now be made in detail to certain embodiments of the subject matter of the present disclosure, examples of which are partially illustrated in the accompanying drawings. While the disclosed subject matter will be described in conjunction with the enumerated claims, it will be understood that the example subject matter is not intended to limit the claims to the disclosed subject matter.

[0024] Vehicle interior systems can include various different curved surfaces designed to be transparent, such as curved display surfaces, and the present disclosure provides articles and methods for forming these curved surfaces including glass substrates. Displays for vehicle interior systems are often equipped with a frame that makes it easier to view the components of the display when the display is open. The frame can also contrast the color or pattern of the display with adjacent automotive interior components. In addition, the frame can provide support for the components of the display.

[0025] Cold forming (e.g., bending) is an energy-efficient method of forming a curved glass substrate having a radius of curvature based on elastic deformation of the glass by the application of out-of-plane loads at relatively low temperatures (e.g., < 140 °C) to form the desired shape. In the cold forming process, a flat high-strength glass substrate is deformed in three dimensions (3D). Typically, the glass substrate is mechanically fixed to a target pre-shaped 3D frame to which, for example, a display functional module is mounted, by an adhesive interlayer. However, this process proves to be difficult because the adhesive interlayer can peel or otherwise separate from one of the glass substrate or the frame.

[0026] The present disclosure provides for improved cold forming methods, systems, apparatuses, and resulting displays in a variety of key areas. According to one embodiment, a new cold forming method is disclosed. With this method, the radius of curvature of a glass substrate can be defined by a template that can not be part of the display. This template, for example, can have movable segments / linkages that can be reusable and / or programmable. This template is referred to herein as a forming apparatus. A bonding medium can be applied to the glass substrate and bonded. The forming apparatus can include, for example, a plurality of linkages, such as flexible webs, chains, or other configurations of linkages discussed herein. The forming apparatus can be bonded to the glass substrate and the bonding medium through the remaining exposed side of the bonding medium. The bonding medium can hold one or more of the plurality of linkages at a desired angle by engaging with one or more surfaces of the linkages that are pressed into the bonding medium for cold forming. Alternative methods of positioning the linkages with the desired angle, sometimes referred to herein as locking, are discussed herein. The assembly, including the glass substrate, the bonding medium, and the forming apparatus, can be held in a vacuum mold or otherwise compressed (e.g., with pressure formed by a mold, etc.) until the bonding medium is strong enough to maintain the desired cold formed curvature. This cold formed curvature can be transferred from the forming apparatus to the glass substrate via the bonding medium. The forming apparatus and / or the bonding medium can then be optionally removed from the display.

[0027] The disclosed method, for example, eliminates the need for a frame as part of the display. However, if utilized, the frame need not be structural in nature. According to some embodiments, the forming apparatus can be held as a backing or can form a frame for the display. This backing can be cut or otherwise shaped to any desired size and match the glass substrate. This variable size can be valuable in high part mix manufacturing operations such as automotive interior manufacturing. Additionally, the disclosed method can eliminate the need to dispense a liquid epoxy (or other adhesive) having a uniform thickness onto a frame, as was the case with previous methods that utilized a structural frame. The lack of adhesive or even variations in the thickness of such adhesive can result in stress concentrations that weaken the display. Utilizing a forming apparatus can avoid these potential issues. According to one embodiment, the forming apparatus can facilitate the use of a structural tape as the bonding medium. This structural tape can be precisely cut to shape. This cutting can be performed prior to removal of the forming apparatus. Further, the forming apparatus can utilize linkages or other movable members, such as segments with hinged joints, such as hinges or other types of connections. These hinges or other hinged connections can cause the structural load on the adhesive to be more concentrated in shear forces rather than static tension forces when forces are transferred from the glass substrate back into the hinges in the forming apparatus. Reducing the static tensile forces (and the resulting stresses) can improve the adhesion between the glass substrate and the bonding medium.

[0028] Further embodiments disclosed herein relate to the construction of a backing and uses thereof. The construction of the backing can be the same as or similar to the construction of the forming apparatus. Indeed, in some embodiments, the forming apparatus can subsequently be used as a backing for the glass substrate, frame, and / or other components of the display. However, this can not be the case in other embodiments. Thus, for example, the forming apparatus can be removed from the display after cold forming, and a separate backing can be installed. The construction of the backing is further discussed herein.

[0029] The backing can enhance the replaceability of the display. For example, if the glass substrate is scratched or broken, a new backing and glass substrate can be utilized to replicate the original substrate. This can be accomplished by flexing the backing and removing the adhesive medium (such as a structural tape) from the glass substrate. This can be done without damaging the display module and touch panel unit. Additionally, according to some embodiments, the backing can enable a flexible display with dynamic flexing capability. More particularly, the backing can be constructed from movable links, segments, sections, hinges, hinged connections, etc. that are selectively movable relative to one another and relative to the glass substrate. This movable construction of the backing can make the backing flexible. An actuator (e.g., one or more motors, one or more links, wire(s) / pulley(s), spool(s), pinion gear(s) / toothed rack(s), one or more hydraulic devices, combinations thereof, etc.) can drive one or more of the links (or another member, if used instead) of the backing to a desired individual position. The actuator can have a construction similar to that of an actuator used to reposition a side mirror of an automobile, for example. The hinges or hinged connections of the backing can be free to move and can not be able to be adhered or otherwise locked in place. Thus, one or more actuators can be attached or otherwise coupled to the backing and can be configured to control and shape the glass substrate of the display via the backing to improve one or more user viewing angles of the display.

[0030] As used herein, the terms "cold forming," "cold formed," "cold bending," or "cold bent," and iterations thereof, refer to bending a glass substrate at a temperature less than the softening point of the glass. The terms "cold bendable," "flexible," or "flexible" refer to the ability of a glass substrate to be cold bent or otherwise geometrically altered (such as using one or more actuators and a backing as described in the detailed description herein to dynamically alter). Figures 8-D

[0031] Figure 1 ​A vehicle interior 10 including three different vehicle interior systems 100, 200, 300 is shown in accordance with example embodiments. The vehicle interior system 100 includes a center console base 110 having a curved surface 120 including a display shown as a curved display 130. The vehicle interior system 200 includes an instrument panel base 210 having a curved surface 220 including a display shown as a curved display 230. The instrument panel base 210 typically includes an instrument cluster 215, which can also include a curved display. The vehicle interior system 300 includes an instrument panel steering wheel base 310 having a curved surface 320 and a display shown as a curved display 330. In one or more embodiments, the vehicle interior system can include a base that is an armrest, a pillar, a seat back, a floor, a headrest, a door panel, or any portion of the interior of a vehicle that includes a curved surface.

[0032] The articles and technology described herein can be used in any one or all of the vehicle interior systems 100, 200, and 300. Thus, they are not limited to displays. Although Figure 1 Automotive interiors are shown, but various embodiments of vehicle interior systems can also be incorporated into any type of vehicle, such as trains, cars (e.g., small cars, trucks, buses, etc.), sea-going vessels (ships, boats, submarines, etc.), and aircraft (e.g., drones, airplanes, jets, helicopters, etc.), including both human-driven vehicles, semi-automated vehicles, and fully-automated driverless vehicles.

[0033] Figure 2 A display 400 for a vehicle interior system is shown in accordance with one embodiment. Reference is made to Figures 3A-D Methods, systems, and apparatuses for forming the display 400 are further discussed. It should be recognized that, Figures 3A-D The technology and apparatuses are not limited to the display 400, but include Figure 1 any display or other vehicle component of those described herein. As Figure 2 shown, the display 400 includes a glass substrate 402 and a frame 404. The frame 404 is entirely optional, and can not be utilized in accordance with some embodiments. The frame 404 can be formed of a backing and / or a bonding medium as further described herein in accordance with some embodiments. The frame 404 can not be used to support (e.g., to facilitate or maintain the curvature of the glass substrate 402), and thus can be non-structural. Structural frames have typically been utilized previously. The frame 404 can be used for aesthetic purposes and to contrast with the display module (not shown). In accordance with some embodiments, the backing can provide support (e.g., to facilitate or maintain the curvature of the glass substrate 402), or a combination of the frame 404 and the backing can be used to support.

[0034] like Figure 2 As shown, the frame 404 includes a first opening 406 configured to accommodate additional display components or modules (not shown). The frame 404 and the glass substrate 402 may include curved portions 408.

[0035] The radius of curvature of the curved portion 408 can be, for example, about 20 mm or more, 40 mm or more, 50 mm or more, 60 mm or more, 100 mm or more, 250 mm or more, or 500 mm or more.

[0036] The glass substrate 402 can be composed of suitable glass compositions for cold-formed glass substrates described herein, including soda-lime glass, alumino-silicate glass, borosilicate glass, boro-alumino-silicate glass, alkali-containing alumino-silicate glass, alkali-containing borosilicate glass, and alkali-containing boro-alumino-silicate glass.

[0037] The glass substrate 402 can be strengthened using any suitable method known in the art, including by including compressive stress (CS) in the glass substrate that extends from the surface to a depth of compression (DOC), by utilizing a mismatch in the coefficient of thermal expansion between portions of the article to create a compressive stress region and a central region exhibiting tensile stress, by thermally heating the glass to a temperature above the glass transition point and then rapidly quenching, and by chemically ion exchanging, in which, for example, larger ions having the same valence or oxidation state are substituted for or exchanged with ions at or near the surface of the glass substrate.

[0038] As used herein, the term "glass substrate" is used in its broadest sense to include any object made wholly or partly of glass. Glass substrates include laminates of glass and non-glass materials, laminates of glass and crystalline materials, and glass-ceramics (including amorphous and crystalline phases). The glass substrate can be transparent or non-transparent. Cold-formed glass substrates can include colorants that provide a particular color.

[0039] The thickness of the glass substrate 402 can be adjusted to allow the glass substrate 402 to be flexible to achieve a desired radius of curvature. Further, a thinner glass substrate 402 can be more easily deformed, which can potentially compensate for shape mismatches and gaps that can be created by the shape of the display 400 (when bent). At least a portion of the glass substrate 402 and the frame 404 can have substantially similar radii of curvature to provide a substantially uniform distance between them.

[0040] The glass substrate 402 can be positioned on the frame 404 and can include a central portion that interfaces with and generally conforms to the corresponding curved portions of the frame 404. As shown, the glass substrate 402 includes a first major surface 410 that directly faces the viewer and a second, opposing second major surface (not numbered) that interfaces with the frame 404 and / or other components.

[0041] The frame 404 has an inner surface that defines the opening 406. The inner surface can provide mechanical alignment for positioning the display module within the opening 406.

[0042] Figure 3A A side of the display 400 opposite Figure 2 is shown, and further illustrates the backing 412 according to one embodiment. The backing 412 can include a plurality of links 414. These links 414 are shown in a schematic manner in Figures 3A-E . The links 414 can be selectively movable, such as relative to one another (and the glass substrate, bonding medium, etc.), as further described subsequently herein. Various embodiments of the backing 412 are contemplated.

[0043] According to Figures 3A-E embodiments of the backing 412 can be a mesh 416, such as, for example, a chain-link mesh. The mesh 416 can have a plurality of links 414 connected together. The links 414 can extend in various directions across the display 400, such as generally longitudinally (left / right in the view plane) from the first edge 415A to the second edge 415B or generally longitudinally adjacent the second edge 415B, and laterally (up / down in the view plane) from the third edge 415C to the fourth edge 415D or laterally adjacent the fourth edge 415D (unless otherwise indicated, these items are numbered only with reference to Figure 3A ). Figures 3A-D The layout and interconnection configuration of the plurality of links 414 shown is exemplary and not limiting. Various layouts and interconnection configurations of the plurality of links 414 are contemplated. The backing 412 can be constructed from any known material, and thus, the backing 412 can be a polymer, metal, ceramic, glass, composite thereof, etc. According to some embodiments, if a mesh 416 is utilized, it can be constructed from fibers or filaments including natural or synthetic fibers.

[0044] Figures 3A-E Various exemplary configurations of the backing 412 are shown. As Figure 3A shown, the backing 412 can substantially occupy the entire second major surface 418 of the display 400. Thus, the backing 412 can extend to or adjacent the first edge 415A, the second edge 415B, the third edge 415C, and the fourth edge 415D. Thus, Figure 3AThe backing 412 can be positioned behind and can support the glass substrate 402 Figure 2 ), the frame 404 Figure 2 ), the display module, and / or other components of the display 400.

[0045] Figure 3B As shown, the backing 412 can be applied, cut, or otherwise positioned around the opening 406 defined by the frame 404 Figure 2 ). Thus, the opening 406 is not covered by the backing 412. Figure 3B The backing 412 can be positioned behind and can support the frame 404 Figure 2 ).

[0046] Figure 3C and Figure 3D As shown, the backing 412 can be applied, cut, or otherwise positioned around or across the opening 406. Thus, the backing 412 can cover only a selective portion of the frame 404. In Figure 3C , the backing 412 extends from or immediately adjacent to the first edge 415A to the second edge 415B or immediately adjacent to the second edge 415B. In Figure 3D , the backing extends from or immediately adjacent to the third edge 415C to the fourth edge 415D or immediately adjacent to the fourth edge 415D. The backing 412 can provide structural support and / or can facilitate bending of the display 400 in selected areas of application, as further discussed herein. By way of example, the backing 412 can facilitate and / or support bending of the display 400 in this intermediate area of the display 400 as illustrated. Figure 3D

[0047] Figure 3E As shown, embodiments in which the backing 412 is separated into different portions 412A and 412B positioned on opposite ends of the display 400, such as at or immediately adjacent to the first edge 415A and at or immediately adjacent to the second edge 415B. The backing 412 can provide structural support and / or can facilitate bending of the display 400 in these selected areas. Figure 3E Embodiments of the display 400 can be further configured to enable the display 400 to be flexible, with dynamic bending capabilities, as further illustrated and discussed in Figure 9A and Figure 9B . Further, Figures 3A-E any embodiment of the display 400 can provide such capabilities, as further discussed herein.

[0048] Figure 4A and Figure 4B As shown, a backing 512 according to an embodiment. Figure 4A ​A first side of the backing 512 is shown, Figure 4B The opposite side of the backing 512 is shown. Unless otherwise indicated, the description of the backing 512 applies to both sides of the backing 512. Figure 4A All reference signs are provided.

[0049] The backing 512 can include a plurality of links 514A, 514B, 514C, 514D, etc., a plurality of articulation joints 516A, 516B, 516C, 516D, etc. For the sake of brevity, only a limited number of links and articulation joints having reference signs are provided, it being understood that the backing 512 can be constructed with any number of links and articulation joints as desired. The backing 512 can optionally include a cover 517 on one or more major surfaces thereof.

[0050] The plurality of links 514A, 514B, 514C, 514D can include metal members having a longitudinal length between the plurality of articulation joints 516A, 516B, 516C, 516D. Taking link 514A as an example, link 514A can extend longitudinally (corresponding to the Cartesian y-axis) from articulation joint 516A to articulation joint 516B. As shown, the plurality of links 514A, 514B, 514C, 514D can be slightly staggered from one another in the transverse direction (corresponding to the Cartesian x-axis) in an alternating fashion. The plurality of links 514A, 514B, 514C, 514D can be joined together in a selectively moveable fashion at the respective plurality of articulation joints 516B, 516C, 516D. Each of the plurality of links 514A, 514B, 514C, 514D can include a hole or other feature of one of the plurality of articulation joints 516A, 516B, 516C, 516D. Figure 4A As shown, the backing 512 can be formed from a plurality of segments 518A, 518B, 518C, 518D, etc., composed of links. These links can include a transversely positioned (spaced apart) plurality of links 514A, 514B, 514C, 514D and a further plurality of links (e.g., links 514AA, 514BB, 514CC, 514DD, links 514AAA, 514BBB, 514CCC, 514DDD, etc.) and can be generally arranged in a parallel fashion to the plurality of links 514A, 514B, 514C, 514D. Together, the plurality of links 514A, 514B, 514C, 514D, etc., 514AA, 514BB, 514CC, 514DD, etc., 514AAA, 514BBB, 514CCC, 514DDD, etc. can define a first major surface 520 and a second major surface 522 of the backing 512.

[0051] Figure 4A

[0052] ​​According to some examples, the plurality of segments 518A, 518B, 518C, 518D can be formed from a plurality of linkages that are integrally formed together and / or connected by transverse members 519 (better illustrated in Figure 5 FIG. 6) or other structures. Thus, according to some examples, linkages 514A, 514B, 514C, 514D, etc., 514AA, 514BB, 514CC, 514DD, etc., 514AAA, 514BBB, 514CCC, 514DDD, etc., can be connected in the transverse direction by components other than the plurality of articulated joints 516A, 516B, 516C, 516D, here transverse members 519, respectively.

[0053] First major surface 520 can be defined by spaced apart side surfaces of the respective linkages of the plurality of segments 518A, 518B, 518C, 518D, etc. Second major surface 522 can be adjoined, for example, by cover 517. Cover 517 can comprise adhesive, foam, rubber, or other desired material.

[0054] The plurality of articulated joints 516A, 516B, 516C, 516D can extend transversely through and connect a plurality of the respective plurality of linkages 514A, 514B, 514C, 514D, 514AA, 514BB, 514CC, 514DD, 514AAA, 514BBB, 514CCC, 514DDD. Thus, for example, articulated joints 516A and 516B can connect linkages 514A, 514AA, and 514AAA together. In addition thereto, linkage 514A can be connected to linkage 514B, as with the case of articulated joint 516B. Linkages 514A, 514AA, and 514AAA can be selectively moveable in unison via articulated joints 516A and 516B in order to maintain first major surface 520 and second major surface 522. Linkages 514B, 514BB, 514BBB, etc., and articulated joints 516C, etc., can be similarly configured. Thus, the plurality of articulated joints 516A, 516B, 516C, 516D can connect the plurality of segments 518A, 518B, 518C, 518D together in a manner that is selectively moveable relative to one another.

[0055] According to embodiments of Figure 4A and Figure 4B , backer 512 can comprise a metal (e.g., aluminum alloy) chain, such as the Lynxmotion Chain Track, commercially available from RobotShop Inc. Although in Figure 4A and Figure 4Bembodiments, the backings disclosed herein need not include a hinged joint, such as a hinge. For example, the filaments, fibers, or other types of mesh can have sufficient flexibility and ability for relative movement such that, according to some embodiments of the backings, a hinged joint is not needed. Although Figure 4A and Figure 4B The hinged joints shown include hinges, but other types of hinged joints are contemplated, such as hinged joints that use folds, creases, slots, hooks, latches, etc.

[0056] Figure 5 A system 600 is shown for forming a backing 512 of Figure 4A and Figure 4B The system 600 includes one or more of a plurality of segments 518A, 518B, 518C, 518D, etc. (only segment 518A and a portion of segment 518B are shown in Figure 5 The segment 518A can include a cross member 519 and a plurality of linkages 514A, 514AA, 514AAA, etc. The hinged joints 516A and 516B can include hinges 604A and 604B. The hinges 604A and 604B can be partially formed by holes 602A and 602B of the plurality of linkages 514A, 514AA, 514AAA, etc., and can also include shafts 606A and 606B and end caps 608A and 608B.

[0057] Figure 5 A portion of the segment 518B is shown having linkages 514B, 514BB, 514BBB, etc. that are configured to be inserted between the plurality of linkages 514A, 514AA, 514AAA, etc. of the segment 518A. The holes of these linkages of the segment 518A that include the plurality of linkages 514A, 514AA, 514AAA, etc. can together define a common hole of the hinge 604B. The shaft 606B and the end cap 608B can be inserted into (or removed from) this common hole.

[0058] The shaft 606A can be configured to be insertable through the holes 602A of the respective linkages 514A, 514AA, 514AAA, etc. (and the holes of additional linkages not illustrated in Figure 5 The end cap 608A may, for example, be insertable in the shaft 606A and in the hole 602A of the linkage 514A. Similarly, the shaft 606B can be configured to be insertable in the manner previously described.

[0059] Figure 5A A system 600 is shown for forming a backing 512 of Figure 4A and Figure 4BAn alternative system 700 to the backing 512. This system 700 may be identical to the previously described system 600, but may also differ: the cross-sections of the holes 702A, 702B, the shafts 706A, 706B, and / or the end caps 708A, 708B may be polygonal (e.g., hexagonal). This configuration of these components allows segment 518A to be selectively positioned and fixed relative to other segments via hinges 704A and 704B (positioning lock). More specifically, shafts 706A and 706B can be removed from segment 518A and adjacent segments. Segment 518A can then be positioned relative to adjacent segments as needed. Shafts 706A and 706B can then be inserted into the corresponding holes 702A, 702B. Due to the shape of shafts 706A and 706B and holes 702A and 702B, segment 518A is immovable relative to adjacent segments (as used herein).

[0060] Although described with reference to polygonal features (e.g., polygonal shafts and holes), backing 512 may be configured to have segments or linkages that can be selectively positioned and fixed (positioned and locked) relative to other segments or linkages by other mechanical mechanisms known in the art. Thus, the articulated joint may utilize snap-fit, snap-connection, interference fit, or other features such as notches, tabs, gears, hooks, racks / pinions, or other matching convex / concave connections. Therefore, according to some embodiments, locking of segments or linkages can be facilitated by any one or a combination thereof by holding multiple linkages in place with an adhesive medium (see following). Figure 6C (as described), by applying a second adhesive to or near the hinge joint to hold multiple linkages (hereinafter referred to) Figure 6B As described, apply adhesive to the hinge joint (see following). Figure 6C (as described), so that the concave portion of the hinge joint matches the convex portion of the hinge joint (refer to...) Figure 5A (as described) or establish a fixed connection at the hinge joint (refer to) Figure 5A (As described).

[0061] Figure 6A A segment 518A of the backing 512 is shown. Segment 518A has an adhesive medium 800 attached to its first primary surface 520. According to one embodiment, the adhesive medium 800 may include a structural adhesive. The structural adhesive may include a polyurethane (e.g., derived from St. Paul, Minnesota). DP604NS, and obtained from Wilmington, Delaware Betamate 73100 / 002, 73100 / 005, 73100 / 010, Betaseal X2500, and BetalinkK2), polysiloxanes, and silane-modified polymers (e.g., derived from...) TEROSON RB IX (also known as TEROSTAT MS 9399 and TEROSON MS 647) and epoxy resin (e.g., derived from St. Paul, Minnesota). Scotch-Weld TM Epoxy resin adhesives DP125 and DP604).

[0062] Other adhesives include, but are not limited to, adhesives selected from one or more of the following categories: (a) toughened epoxy resins (e.g., epoxy powder EP21TDCHT-LO, 3M Scotch Weld epoxy resin DP460, off-white); (b) flexible epoxy resins (e.g., epoxy powder EP21TDC-2LO, 3M Scotch Weld epoxy resin 2216); (c) acrylic and / or toughened acrylic (e.g., LORD adhesives 403, 406, or 410 acrylic adhesive containing LORD accelerator 19 or 19GB w / LORD AP 134 treatment agent, LORD adhesive 850 or 852 / LORD accelerator 25GB, Loctite HF8000, Loctite AA4800); (d) urethane (e.g., 3M Scotch Weld urethane DP640, brown, SikaForce 7570 L03, SikaForce 7550 L15, Sikaflex). 552 and polyurethane (PUR) hot melt adhesives, such as Technomelt PUR9622-02 UVNA, Loctite HHD 3542, Loctite HHD 3580, 3M hot melt adhesives 3764 and 3748; and (e) silicone resins (Dow Corning 995, Dow Corning 3-0500 silicone assembly adhesive, Dow Corning 7091, SikaSil-GP). In some cases, structural adhesives that can be used as sheets or films (e.g., but not limited to: 3M structural adhesive films AF126-2, AF 163-2M, SBT 9263 and 9214, epoxy powder adhesive FLM36-LO) may be used.

[0063] Furthermore, according to some embodiments, pressure-sensitive adhesives such as 3M VHB tape may include an adhesive medium 800. In such embodiments, the use of pressure-sensitive adhesives (such as tapes) allows for the bonding of curved glass substrates to a backing (and / or molding equipment) without a curing step, among other things. Therefore, the adhesive medium 800 may be any one or a combination of VHB tape, foam tape, pre-cured adhesive dots or other shapes, rigid polymers, compliant polymers, or fully or partially cured adhesives.

[0064] The adhesive medium 800 can be rigid, semi-rigid, or compliant. As discussed, for example, the adhesive medium 800 and / or backing 512 (and / or molding equipment) can optionally be used only in critical stress areas to prevent glass compression before the adhesive has fully cured. The backing 512 in contact with the adhesive medium 800, particularly the sides of the linkages 514A, 514AA, 514AAA, etc., can have mechanical features such as grooves, ridges, etc., to, for example, improve the adhesion of the adhesive medium 800, provide alignment, or otherwise improve its performance. The adhesive medium 800 can be sacrificial or permanent. Sacrificial adhesive medium 800 can be cut or otherwise removed and shaped. In some cases, it can be replaced later with another adhesive medium (such as an adhesive).

[0065] according to Figure 6A In one embodiment, the adhesive medium 800 may be cut or otherwise shaped to expose and remove the hinge joints 516A and 516B from the adhesive medium 800. This can facilitate selective movement of segment 518A relative to adjacent segments via hinge joints 516A and 516B, which can benefit the dynamic capabilities of the glass substrate of the backing 512 for the flexural display, as referenced. Figures 8-D Further description.

[0066] The bonding medium 800 can have any desired thickness between the glass substrate and the backing 512. The thickness of the bonding medium 800 can be adjusted to ensure lamination between the backing 512 and the cold-formed glass substrate, among other things. An exemplary thickness of the bonding medium 800 can be 5 mm, 3 mm, 2 mm, 1 mm, 0.5 mm, 0.25 mm, 0.01 mm or less, and can be applied in various ways. The thickness of the bonding medium 420 can be in the range of about 200 pm to about 500 pm, about 225 pm to about 500 pm, about 250 pm to about 500 pm, about 275 pm to about 500 pm, about 300 pm to about 500 pm, about 325 pm to about 500 pm, about 350 pm to about 500 pm, about 375 pm to about 500 pm, about 400 pm to about 500 pm, about 200 pm to about 475 pm, about 200 pm to about 450 pm, about 200 pm to about 425 pm, about 200 pm to about 400 pm, about 200 pm to about 375 pm, about 200 pm to about 350 pm, about 200 pm to about 325 pm, about 200 pm to about 300 pm, or about 225 pm to about 275 pm. In one embodiment, if the bonding medium 800 includes some of the adhesives described above, it can be applied using an applicator gun and mixing nozzle or a pre-mixed syringe or an automatic adhesive dispenser and spread evenly using any of the following (e.g., a roller, a brush, a spatula, or a squeegee).

[0067] The bonding medium 800 can also have any suitable length and / or width as defined by the size of the display as previously described. Thus, the bonding medium 800 is not limited in size in length or width beyond the size of the display in those dimensions.

[0068] Figure 6B An alternative embodiment of one segment 518A of the backing 512 is shown. The segment 518A has a bonding medium 800 attached to a first major surface 520 thereof and a second bonding medium 802 attached to a second major surface 522 thereof. The second bonding medium 802 can have the same or similar material(s) as the bonding medium 800. As shown, the second bonding medium 802 (or indeed the first bonding medium 800) can extend laterally to cover the hinged joints 516A and 516B. When the second bonding medium 802 is cured, this arrangement can lock the segment 518A in position relative to adjacent segments in a similar manner as previously described with reference to the embodiment of FIG. 5. Figure 6B Figure 5A

[0069] Figure 6C ​​As shown, the backing 512 having the plurality of segments 518A, 518B, 518C, and 518D and the linkages 514A, 514B, 514C, and 514D can be selectively moved relative to one another via the plurality of hinges 516B, 516C, and 516D. For clarity, Figure 6C The glass substrate, which is on top of and contiguous with the bonding medium 800, is not illustrated. The selective movement of the plurality of segments 518A, 518B, 518C, and 518D has been completed to provide the desired curvature for the backing 512 between the segments 518A, 518B, 518C, and 518D. This curvature can be transferred to the glass substrate via the bonding medium 800. The bonding medium 800 has been applied to the segments 518A, 518B, 518C, and 518D and over the hinged joints 516A, 516B, 516C, 516D, etc., and as the bonding medium 800 cures or partially cures, it can become integral with the previously referenced Figure 5A The plurality of segments 518A, 518B, 518C, and 518D and the linkages 514A, 514B, 514C, and 514D are locked in position in a manner similar to that described.

[0070] As Figure 6C shown, the radius of curvature of the central portion of the backing 512 and the bonding medium 800 can be within 500 pm or less than the radius of curvature of the curved portion 408( Figure 2 ) of the glass substrate 402( Figure 2 ). This tolerance can be affected by the method and forming equipment used to form the display 400( Figure 2 ), as further discussed with reference to Figure 7A and Figure 7B .

[0071] Figure 7A and Figure 7B A method 900 including a forming apparatus 900 is shown. The forming apparatus 900 can be the backing 412 as previously described. The method 900 can include a forming apparatus 902 that can selectively move its segments and / or linkages to provide a desired curvature (or other shape) of the forming apparatus 900. The method 900 is illustrated with reference to a test mold including clamps and a platen. However, it is contemplated that the method 900 can utilize a vacuum forming apparatus (also referred to as a vacuum chuck) to cold form the glass substrate 402 as previously discussed. Such vacuum forming apparatuses are known in the art for cold forming. A plenum or one plenum such as defined by one or both of the platen or other device can facilitate a pressure differential with the forming apparatus and / or the glass substrate.

[0072] As in Figure 7AAs best shown, the forming apparatus 902 can optionally be positioned between opposing platens that interface with the glass substrate, with the bonding medium positioned therebetween in the manner previously described. The bonding medium can be applied to the glass substrate and bonded. The forming apparatus can be bonded to the glass substrate and the bonding medium through the remaining exposed side of the bonding medium. The bonding medium can hold one or more of the plurality of linkages (or one or more segments of the plurality of segments) at a desired angle for cold forming by engaging one or more surfaces of the linkage that are pressed into the bonding medium. Various features or techniques for securing (sometimes referred to herein as locking) the linkages at a desired angle have been previously discussed herein. The assembly (including the glass substrate, the bonding medium, and the forming apparatus) can be held in a vacuum mold or otherwise compressed (e.g., with pressure formed by the mold, etc.) until the bonding medium is sufficiently strong to maintain the desired cold forming curvature. This cold forming curvature can be transferred from the forming apparatus to the glass substrate via the bonding medium. The forming apparatus and / or the bonding medium can then be optionally removed from the display.

[0073] According to one embodiment of the method, the radius of curvature of the glass substrate can be defined by a forming apparatus 902 as previously described. Looking back, the forming apparatus 902 can or can not be part of the display. The forming apparatus 902 can have movable segments / linkages to achieve the desired radius of curvature, as previously described. For example, the segments / linkages can be reusable and / or programmable.

[0074] Thus, Figure 7A and Figure 7B A method 900 of cold forming a display, console, or other feature or component for a vehicle interior system is illustrated according to one embodiment. The method 900 can include applying an adhesive to a glass substrate, positioning a forming apparatus 902 on the glass substrate with the adhesive positioned therebetween such that the forming apparatus is coupled to the adhesive, wherein the forming apparatus includes a plurality of linkages configured to be selectively movable to assume a radius of curvature along a first major surface of the forming apparatus, applying a desired force to the glass substrate and the forming apparatus 902 to compress the adhesive, and maintaining the desired force applied to compress the adhesive for a desired duration of time with the glass substrate clamped to the forming apparatus. The method 900 can also optionally include locking an articulating joint to position one of the plurality of linkages relative to at least another of the plurality of linkages and to reduce or eliminate substantial relative movement between the one of the plurality of linkages and the at least another of the plurality of linkages.

[0075] Figure 8A portion of a display 1000 is shown undergoing a flexure of its glass substrate 1002. This flexure forms a radius of curvature in this glass substrate 1002. The flexure of the glass substrate is performed by a backing 1004 (e.g., the same as or similar to backing 512) used in combination with an actuator 1006. This combination of the backing 1004 and the actuator 1006 can facilitate dynamic movement of the display 1000. According to Figure 9A and Figure 9D The actuator 1006 can include a spool (not shown) that utilizes a wire or other line coupled to a first portion 1004A of the backing 1004 and a second portion 1004B of the backing 1004. The first portion 1004A and the second portion 1004B can be located on opposite ends of the display 1000.

[0076] Figures 9A-D A method 1100 of dynamically altering a shape of a display 1101 is illustrated. The display 1101 can include a glass substrate 1102, a backing 1104 (such as any of those previously described), and optionally a frame 1105. Figure 9A A separate backing 1104 is shown prior to application to the glass substrate 1102 and the frame 1105 via a bonding medium as previously described. Figure 9B The backing 1104 is shown attached to the glass substrate 1102 and the frame 1105. Figure 9C It is shown that at least one actuator 1106 (here a plurality of motors 1108 with shafts 1110) can be coupled to particular one or more segments or one or more links of the backing 1104. The at least one actuator 1106 can be arranged to extend across a portion or all of the backing 1104. Figure 9D It is shown that the at least one actuator 1106 can move particular one or more segments or one or more links of the backing 1104. This can facilitate dynamic movement of the display 1101, such as to form a curved region 1112 along a surface of its glass substrate 1102.

[0077] Values stated in a range format should be interpreted in a flexible manner to include both the numerical values explicitly recited as limits of the range and to include all individual numerical values or sub-ranges within that range, as if each numerical value and sub-range were explicitly recited. For example, a range of "about 0.1 % to about 5%" or "about 0.1 % to 5%" should be interpreted to include not only the explicitly recited values and ranges, but also the individual values (e.g., 1 %, 2%, 3%, and 4%) and the sub-ranges (e.g., 0.1 % to 0.5%, 1.1 % to 2.2%, 3.3% to 4.4%) within the indicated ranges. The statement "about X to Y" has the same meaning as "about X to about Y," unless otherwise indicated. Likewise, the statement "about X, Y, or about Z" has the same meaning as "about X, about Y, or about Z," unless otherwise indicated.
