DETAILED DESCRIPTION OF THE INVENTION

[0004] It should be understood that the present invention can take various alternative orientations unless explicitly specified to the contrary. It should also be understood that the specific apparatus and processes shown in the accompanying drawings and described in the following specification are merely exemplary configurations of the inventive concept defined in the appended claims. Therefore, specific dimensions and other physical characteristics related to the configurations disclosed herein should not be considered limiting unless explicitly stated otherwise in the claims. Further, unless otherwise specified, discussions of a particular feature or component extending in a given direction or along that direction do not, unless otherwise specified, imply that the feature or component follows a straight line or axis in that direction, or that it extends only in that direction or in such a plane without components or deviations in other directions.

[0005] Referring now to the figures, in which like numerals indicate corresponding parts throughout the several views, the construction of a flash glass system 10 is shown throughout and will be described in detail hereinafter. The flash glass system 10 is configured for use in a vehicle 12 such as a passenger car, truck, or other transportation vehicle. As shown in FIG. 1, the vehicle 12 includes a plurality of doors 14. Specifically, front and rear passenger doors are shown. Each door 14 has a frame 16 (which may also be referred to as a door frame) that defines at least one window opening. It will be understood that the frame 16 may include a plurality of frame members or plates. A movable window 18 (which may also be referred to as a glass window 18 or window 18) is positioned within the window opening of each door 14. The movable window 18 is movable between an open position and a closed position relative to the frame 16 of each door 14.

[0006] As shown in FIGS. 2A-2C, 8, 16, 21, 26, and 31, the movable window 18 includes an outer surface 17A, an inner surface 17B, and an edge portion 17C surrounding the window 18. Further, it will be understood that the window 18 includes a glass plate 17 (which may also be referred to herein as a glass piece) and a guide structure 19 (which may also be referred to herein as a sliding arm 19 or a sliding block structure) coupled to the glass plate 17. The glass plate 17 further defines the outer surface 17A, the inner surface 17B, and the edge portion 17C. In the illustrated configuration, the guide structure 19 is coupled to the inner surface 17B of the glass plate 17 and moves with the glass plate 17 as the window 18 moves between the open and closed positions. The phrase "movable window" as described herein includes a glass plate (or glass piece) and a guide structure (or sliding arm or sliding block structure) coupled to the glass plate, and both the glass plate and the guide structure are movable as a unit. The guide structure 19 will be described in further detail below.

[0007] When window 18 is closed or in the closed position, its outer surface is adapted to be flush with the outer surface 34 of the exterior of vehicle 12 and / or adjacent elements (such as trim panels or upholstery). As described herein, the term "flush" in this document is interpreted to mean that, at least from a visual perspective, there is little or no perceived level difference between the surfaces. In the context of a vehicle, when the movable window 18 is in the closed position, it is "flush" with the upper and / or side body components that surround the window opening closed by window 18. Thus, when viewed from the outside, window 18 appears not to recess relative to vehicle door 14 or door components (such as trim panels or upholstery) and / or another window 18 when fully closed. Rather, a continuous planar impression of glass and body surface is created on the exterior of vehicle 12. It should be understood that these components may not be exactly on the same plane and that some parts (such as part of a seal) may protrude slightly. Vehicle 12 of FIG. 1 is an example of an application suitable for a flush glass system 10, but this design is not limited to vehicle applications. Benefits can be obtained from the use of this design for stationary or mobile machines or products, provided they are appropriately scaled and configured for a particular application.

[0008] Referring to the schematic diagrams 2A to 4, the flash glass system 10 includes a trim panel 20 that defines a first channel 22 extending along a channel axis CA, as disclosed herein. As shown in these figures, the flash glass system 10 is attached to the rear passenger door. The channel axis CA may be curved or straight, depending on the desired design. As is known in the industry, this type of trim panel 20 is also called an up-ric. An up-ric often has a decorative appearance. The first channel 22 is configured to accommodate a seal (described below) and guides the movement of the window 18 as the window 18 moves between a closed position (see FIG. 2A) and an open position (see FIGS. 2B and 2C), and vice versa. The first channel 22 is integrated with the trim panel 20. In other words, the trim panel 20 and the first channel 22 are integral components, and the first channel 22 extends along an extension of the trim panel 20 or at least a part of the trim panel 20. By integrating the first channel 22 with the trim panel 20, an optimal fit and assembly of a part of the window 18 to the trim panel 20 are achieved. As described above and explained in more detail below, the movable window 18 preferably has a guide structure 19 that is received within the first channel 22 to guide the window during movement.

[0009] Referring also to FIGS. 8 - 14 and FIGS. 20 - 31, the flush glass system 10 further includes a seal assembly 74 that includes a seal 76 configured to help protect the interior of the vehicle 12 from the external environment. As shown in these figures, the flush glass system 10 is installed on the passenger side door. It will be understood that this type of flush glass system can be installed at any suitable location on the vehicle. The first channel 22 is shaped to receive the seal assembly, and the seal assembly includes an outer seal lip 72 for sealing around the edge of the window 18. In the preferred embodiment shown, the seal is partially attached within the first channel 22 of the trim panel. More preferably, the seal is attached only within the first channel 22. It is contemplated that the first channel 22 may include an integral seal assembly formed directly in a portion of the channel rather than a separate insertable seal assembly. The seal assembly 74 will be discussed in more detail below.

[0010] As shown in FIGS. 2A - 2C, 8, and 15 - 16, the flush glass system 10 further includes a lower belt member 24 disposed within the door 14, and the lower belt member 24 defines a second channel 26 that extends along a channel axis CA. The second channel 26 is configured to guide the guide structure 19 of the window 18 as the window 18 moves between an open position and a closed position. In this way, the window 18 is guided along the channel axis CA as it moves up and down between the open position and the closed position. The first channel 22 of the trim panel 20 and the second channel 26 of the lower belt member 24 at least partially follow along the vertical extent of the vehicle 12 from the upper end 28 to the lower end 30 of the vehicle 12. The first channel 22 and the second channel 26 are described herein as the "first channel" and the "second channel", but the specific order of the channels can be changed, and it will be understood that the terms "first channel" and "second channel" are used only to distinguish the channels from other channels and do not indicate any special meaning in their order.

[0011] The lower belt member 24 further includes an outer branch portion 58 (also referred to as an outer member or an outer portion) and an inner branch portion 60 (also referred to as an inner member or an inner portion), and these are connected to each other spaced apart by a base 62 (also referred to as a base member or a base portion). The outer branch portion 58, the inner branch portion 60, and the base 62 of the lower belt member 24 further define a second channel 26. The outer branch portion 58 extends at least partially, or in some configurations, substantially parallel to the inner branch portion 60. The outer branch portion 58 and the inner branch portion 60 extend at least partially, or in some configurations, substantially parallel to each other in the vertical extent of the vehicle 12. The outer branch portion 58 and the inner branch portion 60 extend in the vertical direction of the vehicle 12 from the lower end 64 to the upper end 66 of the lower belt member 24.

[0012] The outer branch portion 58 and the inner branch portion 60 of the lower belt member 24 extend from the lower end 64 to the flare portion 68 at the upper end 66 of the lower belt member 24. The flare portion 68 flares out in a flared shape such that the second channel 26 widens at the upper end 66 of the lower belt member 24. It will be understood that the second channel 26 may be configured to flare out in a fan shape, flare out, or widen in some other way at the upper end 66 of the lower belt member 24. The lower belt member 24 is oriented such that the flare portion 68 faces towards the trim panel 20. The flare portion 68 ensures that the window 18 is properly guided between the first channel 22 of the trim panel 20 and the second channel 26 of the lower belt member 24. In some configurations, the flare portion 68 is integral with the outer branch portion 58 and the inner branch portion 60, and the outer branch portion 58 and the inner branch portion 60 flare outwards or transition outwards at the upper end 66 of the lower belt member 24. In such configurations, the outer branch portion 58 and the inner branch portion 60 extend substantially parallel to each other, and at the flare portion 68, the outer branch portion 58 and the inner branch portion 60 extend away from each other or extend outwards. In other words, the second channel 26, which is partially defined by the outer branch portion 58 and the inner branch portion 60, may gradually widen at the upper end 66 of the lower belt member 24. In some configurations, the flare portion 68 is a separate component coupled to at least one of the outer branch portion 58 and the inner branch portion 60. In these configurations, the flare portion 68 can be coupled to at least one of the outer branch portion 58 and the inner branch portion 60 by adhesive bonding, welding, mechanical fastening, or any other suitable method. Other configurations are also contemplated. It will be understood that the flare portion 68 may be integral with or coupled to both or one of the outer branch portion 58 and the inner branch portion 60. Further, it will be understood that in some configurations, the flare portion can include a tapered portion or a narrowed portion to ensure that the window 18 is properly guided between the first channel 22 of the trim panel 20 and the second channel 26 of the lower belt member 24.

[0013] The inner bifurcation of the lower belt member 24 further includes a plurality of protrusions 52 that define alternating slots. The protrusions 52 can include a flat upper surface to assist in supporting the guide structure 19 of the window 18 when the guide structure 19 is disposed within the second channel 26. A second seal is inserted into the second channel 26, and a portion of the second seal abuts against the protrusions 52 and otherwise occupies the second channel 26. Preferably, the second seal is attached only to the second channel. Generally, the protrusions 52 are shown in a rectangular shape. It will be understood that the shapes of the protrusions 52 in FIGS. 2A-2C are shown in a more specific configuration than those shown in FIGS. 8 and 15-16 and are shown generally and / or schematically. The protrusions 52 can have any suitable shape and / or configuration. Further, it will be understood that the protrusions 52 can be any type of component that facilitates at least one of guiding, positioning, and holding, such as, but not limited to, tabs, flaps, extensions, protrusions, lips, fingers, flanges, etc.

[0014] The outer bifurcation of the lower belt member 24 further includes a plurality of second passages 90. The passages are preferably aligned with the protrusions 52.

[0015] The movement of the guide structure 19 of the window 18 can pass continuously through the trim panel 20 and the lower belt member 24 by the first channel 22 of the trim panel 20 and the second channel 26 of the lower belt member 24. As a result, the guiding and mounting of the window 18 are improved, and the assembly time is shortened. Both the first channel 22 of the trim panel 20 and the second channel 26 of the lower belt member 24 extend along the channel axis CA. In other words, the first channel 22 and the second channel 26 are aligned to guide the guide structure of the window 18 between the trim panel 20 and the lower belt member 24 when the window 18 moves from the closed position to the open position or vice versa. In other words, the trim panel 20 and the lower belt member 24 are aligned in a straight line with each other such that the channel axis CA of the first channel 22 is aligned with (e.g., parallel or coincident with) the channel axis CA of the second channel 26. It will be understood that the channel axis CA may be curved or bent to correspond to the curvature of the vehicle 12.

[0016] To maintain clarity and consistency, certain structural features described below are not individually shown in FIGS. 2A - 2C but may be found in other figures. FIGS. 2A - 2C illustrate the operation of the movable window 18. FIG. 2A shows a scenario where the window 18 is disposed within the first channel 22 of the trim panel 20 and is positioned in a closed position to show the window 18 being closed. In FIG. 2B, a state where the window 18 has descended or moved along the channel axis CA is shown, depicting a scenario where the window 18 moves from the closed position towards the open position, at least partially exposing the interior of the vehicle 12 to the external environment. Here, a part of the guide structure of the window 18 remains disposed within the first channel 22 of the trim panel 20, and another part of the guide structure of the window 18 is disposed within the second channel 26 of the lower belt member 24. Due to the alignment of the first channel 22 and the second channel 26, when the guide structure of the window 18 enters the second channel 26 of the lower belt member 24, the movement of the guide structure of the window 18 can be continuous. In FIG. 2C, a state where the window 18 has further descended or moved along the channel axis CA is shown, depicting a scenario where the window 18 is in a different open position from that in FIG. 2B, further exposing the interior of the vehicle 12 to the external environment. Here, compared with FIG. 2B, a larger portion of the guide structure of the window 18 is disposed within the second channel 26 of the lower belt member 24. The extent of the first channel 22 and the second channel 26 is sufficient to provide the selected mobility for the guide structure of the window 18. Although not shown here, it will be understood that a mechanism may be provided in relation to the vehicle door 14 to raise and lower the window 18.

[0017] In a preferred configuration, the trim panel 20 and the lower belt member 24 are formed as separate components. In other words, the lower belt member 24 is formed separately from the trim panel 20. In such a configuration, the trim panel 20 and the lower belt member 24 may be formed by separate molding steps or operations. The trim panel 20 and the lower belt member 24 are configured to be separately attached to the vehicle door 14, more specifically, to the frame 16 of the door 14. As described above, the movement of the window 18 can continuously pass through the trim panel 20 and the lower belt member 24 by the first channel 22 of the trim panel 20 and the second channel 26 of the lower belt member 24. As a result, the guiding and attachment of the window 18 are improved and the assembly time is shortened. Since the trim panel 20 and the lower belt member 24 are formed separately and attached separately during the assembly of the door 14, in some configurations, the lower belt member 24 is first attached to the door 14. When the lower belt member 24 is attached, the guide structure of the window 18 is disposed within the second channel 26 of the lower belt member 24. In this way, the guide structure of the window 18 can be easily slid into the second channel 26 during assembly. Thereafter, the trim panel 20 is attached to the door 14. The guide structure of the window 18 is disposed within the second channel 26 of the lower belt member 24 before the first channel 22 of the trim panel 20. In this way, the time for attaching the window 18 during assembly is shortened.

[0018] Here, with reference to FIGS. 3 - 6 and FIGS. 8 - 12, the trim panel 20 will be discussed in further detail. The trim panel 20 has a generally elongated structure with a first or upper end 28 and a second or lower end 30. The trim panel 20 includes an exterior member 32. The exterior member 32 can have various finishes such as low gloss black, high glass black, and chrome. As described above, the trim panel 20 and / or the exterior member 32 are also known as an applique. The exterior member 32 includes an outer surface 34 intended to face the exterior of the vehicle 12 and an inner surface 36 intended to face the interior of the vehicle 12. The outer surface 34 of the exterior member 32 is visible from the exterior of the vehicle 12. The trim panel 20 and the movable window 18 can appear between them (the outer surface 34 and the inner surface 36) and / or can be flush - connected. The trim panel 20 and the window 18 can be arranged in any configuration such that the outer surface 34 of the exterior member 32 of the trim panel 20 and the window 18 are flush - connected. The term "flush" has been explained above.

[0019] The glass plate 17 of the movable window 18 is spaced apart from the exterior member 32 of the trim panel 20, forming a gap or space between the exterior member 32 and the edge of the glass plate 17. This gap is schematically shown in FIGS. 2A - 2C and is detailed in FIGS. 8 and 16. The outer seal lip 72 of the seal 76 is disposed within the gap and seals the window 18 from the elements, as will be discussed in more detail below.

[0020] The trim panel 20 further includes an outer branch portion 38 (also referred to as an outer member, outer portion, or connection plate) and an inner branch portion 40 (also referred to as an inner member, inner portion, or connection plate), which are spaced apart and connected to each other by a base 42 (also referred to as a base member, base portion, or connection plate). In some configurations, the outer branch portion 38 is coupled to the inner surface of the exterior member 32. In other configurations, the outer branch portion 38 is coupled to a connection bracket 108, and the connection bracket 108 is coupled to the exterior member 32. The outer branch portion 38 extends at least partially, or in some configurations, substantially parallel to the inner branch portion 40. The outer branch portion 38 and the inner branch portion 40 extend at least partially, or in some configurations, substantially parallel to the exterior member 32 and in the vertical direction of the vehicle 12. The outer branch portion 38 and the inner branch portion 40 extend in the vertical direction of the vehicle 12 from the upper end 28 to the lower end 30 of the trim panel 20. In some configurations, the outer branch portion 38 and the inner branch portion 40 extend beyond the exterior member 32. It is contemplated that the outer branch portion 38 and the inner branch portion 40 can extend beyond the exterior member 32 in any direction. It will be understood that the outer branch portion 38, the inner branch portion 40, and the base 42 may in some configurations be referred to herein as connection plates. Further, it will be understood that any number of connection plates can be included in the trim panel 20.

[0021] The outer branch portion 38, the inner branch portion 40, and the base 42 of the trim panel 20 further define the first channel 22. In some configurations, the outer branch portion 38 may be integrated with the exterior member 32, and it is conceivable that the exterior member 32, the inner branch portion 40, and the base 42 further define the first channel 22. In the illustrated configuration, the first channel 22 is substantially "U"-shaped and extends along the trim panel 20 from the upper end 28 to the lower end 30 of the trim panel 20. In particular, the shapes of the first channel 22 and the second channel 26 are shown generally and / or schematically, and the "U"-shapes of the first channel 22 and the second channel 26 may not necessarily be perfect "U"-shapes. Alternatively, the first channel 22 and the second channel 26 may have any suitable shape and / or configuration.

[0022] The trim panel 20 includes a flare portion 44 where the lower end 30 of the trim panel 20 is flared, and the first channel 22 extends at the lower end 30 of the trim panel 20. The flare portion 44 is shown in FIGS. 2A - 4 and 6 and is shown in phantom lines in FIG. 8. In a preferred embodiment, the flare portion 44 has a complementary configuration to the flare portion 68 of the lower belt member 24. It will be understood that the first channel 22 can be configured to flare out, be flared, or otherwise expand at the lower end 30 of the trim panel 20. The trim panel 20 is oriented such that the flare portion faces towards the lower belt member 24. More specifically, the trim panel 20 is oriented such that the flare portion 44 of the trim panel 20 faces towards the flare portion 68 of the lower belt member 24. The flare portions 44, 68 ensure that the window 18 is properly guided between the first channel 22 of the trim panel 20 and the second channel 26 of the lower belt member 24. In some configurations, the flare portion 44 is integrated with the outer branch portion 38 and the inner branch portion 40, and the outer branch portion 38 and the inner branch portion 40 extend outwardly or transition outwardly at the lower end 30 of the trim panel 20. In such a configuration, the outer branch portion 38 and the inner branch portion 40 extend substantially parallel to each other, and in the flare portion 44, the outer branch portion 38 and the inner branch portion 40 extend away from each other. In other words, the first channel 22, which is partially defined by the outer branch portion 38 and the inner branch portion 40, can gradually widen at the lower end 30 of the trim panel 20. Further, in such a configuration, the outer branch portion 38 and the inner branch portion 40 can extend obliquely with respect to the exterior member 32. On the other hand, in other configurations, the flare portion 44 is a separate component coupled to at least one of the outer branch portion 38 and the inner branch portion 40. In these configurations, the flare portion 44 can be coupled to at least one of the outer branch portion 38 and the inner branch portion 40 by adhesive bonding, welding, mechanical fastening, or any other suitable method. Other configurations are also conceivable. It will be understood that the flare portion 44 can be integrated with or coupled to both or one of the outer branch portion 38 and the inner branch portion 40.Furthermore, in some configurations, the flare portion 44 can include a tapered or narrowed portion to ensure that the window 18 is properly guided between the first channel 22 of the trim panel 20 and the second channel 26 of the lower belt member 24.

[0023] The outer portion of the trim panel 20 further includes an outer branch having attachment features 46. The attachment features 46 define passages that alternate along the outer branch. The attachment features are defined herein as features that facilitate attaching the trim panel 20 to any component of the vehicle door 14, such as the frame 16, or the vehicle 12. The attachment features 46 are associated with the first channel 22 of the trim panel 20. The attachment features 46 are adapted to accommodate any type of fastener or the like and, at the same time, provide clearance for the guide structure of the window 18 to move unobstructed between a closed position and an open position along the channel axis CA. For example, in some configurations, the attachment features 46 can define one or more holes 48 shaped to accommodate a fastener (not shown) or the like. The fastener extends through the holes and can attach the trim panel 20 to the frame 16 of the vehicle door 14 or any other component of the vehicle. The fastener can be any type of fastener or securing mechanism, including but not limited to nails, bolts, screws, and clips. In some configurations, the attachment features 46 can form one or more recesses shaped to facilitate attaching the trim panel 20 to the vehicle door 14. The attachment features 46 can include any number of openings, holes, recesses, or combinations thereof. The openings, holes, and / or recesses of the attachment features 46 are formed along the outer branch spaced apart from each other and can couple the outer portion and the entire trim panel to any component of the frame 16 or the vehicle 12.

[0024] The inner bifurcation of the trim panel 20 further includes a plurality of spaced-apart protrusions 50 that define alternating slots. Generally, the protrusions 50 are shown in a rectangular shape. It will be understood that the shapes of the protrusions 50 in FIGS. 2A-5 are shown generally and / or schematically, and more specific views of the protrusions 50 are shown in FIGS. 8-12. The rectangular shape of the protrusions 50 need not necessarily be rectangular. The protrusions 50 can have any suitable shape and / or configuration. Further, it will be understood that the protrusions 50 can be any type of component that facilitates at least one of guiding, positioning, and holding, such as, but not limited to, tabs, flaps, extensions, protrusions, lips, fingers, flanges, etc.

[0025] Referring to FIGS. 6 and 7, the trim panel 20 can include an attachment feature 54. This attachment feature 54 is optional and is defined herein as a feature that facilitates attaching the exterior member 32 of the trim panel 20 to the vehicle door 14. Here, the attachment feature 54 is schematically shown and is positioned relative to the inner surface 36 of the trim panel 20. Although the attachment feature 54 is depicted on the inner surface 36 of the exterior member 32, it will be understood that the attachment feature 54 may be positioned relative to any component of the trim panel 20. In some configurations, the attachment feature 54 is integrated with the exterior member 32 of the trim panel 20. The attachment feature 54 can include, but is not limited to, any type of attachment member such as a snap, hook, clamp, clip, or adhesive. The vehicle door 14 can include any component of the vehicle door 14 and can at least partially intervene between the exterior member 32 and the attachment feature 54, thereby facilitating attaching the trim panel 20 to the vehicle door 14. For example, in some configurations, the attachment feature 54 includes a hook portion 56 (best shown in FIG. 7) extending from the exterior member 32. More specifically, the hook portion 56 (which may be referred to herein as a bent portion) extends from the edge of the exterior member 32 and is at least partially curved toward the base 42. The hook portion 56 may be dimensioned and / or shaped to receive an edge or a portion of the frame 16 of the vehicle door 14 in order to secure the trim panel 20 to any component of the vehicle 14 such as the vehicle door 14 or the frame 16. The hook portion 56 can receive an edge or a portion of the frame 16 such that the frame 16 is interposed between the hook portion 56 and the inner surface 36 of the exterior member 32. In this way, the trim panel 20 is securely attached to the vehicle door 14. It will be understood that having the hook portion 56 as shown in the figure is optional. The attachment feature 54 can be used to align the trim panel 20 relative to the lower belt member 24 in a manner similar to that shown and described above. It will be understood that the attachment feature 54 may be a continuous or segmented feature extending along the trim panel 20.Furthermore, FIGS. 6 and 7 will be understood to illustrate an exemplary configuration of the attachment feature 54. Other configurations of the attachment feature 54 are also contemplated.

[0026] The present disclosure also includes a method of attaching the flash glass system 10. A particular drawback of the attachment is the number of components that need to be fixedly attached together to the vehicle door. Since a plurality of components need to be fixedly attached together and then attached to the vehicle door, the assembly time is lengthened. Further, another drawback of the particular attachment is that the trim panel and the lower belt member may be formed together and may need to be assembled simultaneously, which takes time and is difficult for attaching the glass plate. In particular, the parts of the trim panel and / or the lower belt member need to be bent or manipulated to slide the glass plate into the channels of the trim panel and / or the lower belt member. Since this must be done, the assembly time is further lengthened. The flash glass system 10 described herein addresses these drawbacks and shortens the assembly time.

[0027] To install the flash glass system 10, the installation method includes the steps of attaching the lower belt member 24 to the vehicle door 14 and sliding the guide structure 19 of the movable window 18 downward along the second channel 26 of the lower belt member 24. Once the movable window 18 is installed, the method includes positioning the trim panel 20 adjacent to the lower belt member 24 and simultaneously sliding the guide structure 19 of the movable window along the first channel so that the first channel of the trim panel aligns with the second channel of the lower belt member. Next, the trim panel 20 is attached to the vehicle door 14. To position the trim panel 20, in some configurations, the method includes positioning the flare portion 44 of the trim panel 20 adjacent and facing the lower belt member 24 and assisting in aligning the first channel 22 and the second channel 26 along the channel axis CA. In some configurations, the method includes positioning the flare portion 68 of the lower belt member 24 toward the upper end of the vehicle door 14. As shown throughout the figure, the trim panel 20 is arranged such that the flare portion 44 of the trim panel 20 faces the flare portion 68 of the lower belt member 24. In this way, the first channel 22 of the trim panel 20 is aligned with the second channel 26 of the lower belt member 24, allowing the movable window 18 to move continuously as the movable window 18 moves between the closed position and the open position.

[0028] Referring particularly to FIGS. 8 - 19, the flash glass system 10 includes a seal assembly 74 including a seal 76 and a guide structure 19. The guide structure 19 is slidably coupled to the seal 76 and is movable relative to the seal 76. As described above, the movable window and glass plate 17 have an outer surface 17A, an inner surface 17B, and an edge portion 17C, and the guide structure 19 is coupled to the inner surface 17B of the glass plate 17. The guide structure 19 is movable with the glass plate 17 when the window 18 moves between the open and closed positions. As discussed elsewhere, the guide structure 19 has a limiting portion and a contact portion such that at least three sides or surfaces engage the seal to support the glass plate 17 of the movable window 18 throughout the movement of the movable window 18. By the three engaging sides, the guide structure and the movable window are supported against longitudinal movement relative to the vehicle as well as lateral movement relative to the vehicle.

[0029] In some configurations, the guide structure 19 includes a body portion 78 (which may be referred to herein as a connecting body), a connecting portion 80, a first limiting portion 82 (which may be referred to herein as a first raised structure or a first raised portion), a second limiting portion 84 (which may be referred to herein as a second raised structure or a second raised portion), and a contact portion 86 (which may be referred to herein as a contact leg). It will be understood that these terms may be used interchangeably unless otherwise specified. In some configurations, the connecting portion 80 of the guide structure 19 is coupled to the inner surface 17B of the glass plate 17 and supports the glass plate 17 as the movable window 18 moves between the closed and open positions.

[0030] Seal 76 includes a plurality of seal portions having an outer seal lip 72. The outer seal lip 72 is disposed between the edge of the window and the trim panel and fills a gap formed between the window and the trim panel. This feature of filling the gap will be further described below. Also, in certain embodiments, seal 76 can include an outer seal lip 72, a second seal portion 100, a third seal portion 102, and a fourth seal portion 104. The specific configuration of seal 76 and the portions will be discussed in more detail below. It is contemplated that seal 76 can include any number of seal portions. The plurality of seal portions are formed of a polymeric material such as one or more types of EPDM (ethylene propylene diene monomer) rubber and / or TPV (thermoplastic vulcanizate) rubber. The configuration of seal 76 including a plurality of seal portions will be discussed in more detail below.

[0031] Seal 76 is received in the first channel 22 of trim panel 20 and can be properly fixed by means such as an adhesive or mechanical interference. In other words, seal 76 is disposed within the first channel 22 of trim panel 20 and is fixed to the trim panel by an interference fit, a tension fit, a press fit, a slip fit, or other suitable fixing method, and / or any combination of fixing methods.

[0032] Referring to FIGS. 16 - 19, the opposite side of the trim panel of the flash glass system 10 is shown. The trim member 130 is attached to the vehicle frame in the same manner as the trim panel. The trim member seal 132 is disposed within the trim member 130 in the same manner as the seal disposed within the trim panel. The edge on the opposite side of the window engages with the outer seal lip 72 of the trim member seal 132 in the same manner. Also, a second guide structure 134 is attached to the edge on the substantially opposite side of the window, and the second guide structure 134 engages with the trim member seal 132 disposed within the trim member 130 to guide the edge on the opposite side of the movable window. The second guide structure 134 has at least one first restriction portion 82 and at least one first elastic member 94. As shown, there is a series of first restriction portions 82 and a series of first elastic members 94. The second guide structure 134 also has a connection portion 80 and a contact portion 86. These features are similar to the features described above and below, but the second guide structure 134 is configured differently from the guide structure 19 in that it holds the window against lateral movement relative to the guide structure but does not restrict the movement of the window along the longitudinal axis of the vehicle. That restricted movement is controlled by the guide structure 19 disposed within the trim panel 20. The guide structure 19 and the second guide structure 134 function in cooperation to hold the window 18 within the door. Also included is a second lower belt member 136 adjacent to the trim member. The second lower belt seal 138 is disposed within the second lower belt member 136 in a complementary manner to the lower belt seal within the lower belt member. Both the trim member and the second lower belt member include corresponding flare portions 140, 142, similar to the trim panel and the lower belt member.

[0033] Here, with specific reference to FIGS. 20 to 24, according to another embodiment, a flash glass system 10 (which may be referred to as a flat door system in this specification) includes a sliding block structure 19, a glass piece 17, and a trim panel structure. The sliding block structure 19 includes a connection structure, a first raised structure 82, and a second raised structure 84. The connection structure includes a connection body 78 and a connection portion 80. The connection body 78 and the connection portion 80 are fixedly connected to each other. The connection body 78 has a first wall surface and a second wall surface. The first wall surface and the second wall surface are arranged to intersect each other. The first raised structure 82 is arranged to protrude along a direction perpendicular to the first wall surface, and the second protruding (raised) portion 84 is arranged to protrude along a direction perpendicular to the second wall surface. The glass piece 17 is connected to the connection portion 80. The trim panel structure includes a trim panel 20 slidably connected to the sliding block structure 19. The connection body 78 extends along the sliding direction of the connection body 78. A first guide portion and a second guide portion are arranged on the trim panel 20. The first guide portion is slidably connected to the first raised structure 82, and the second guide portion is slidably connected to the second raised structure 84.

[0034] In the flat door system provided with this configuration, the connecting portion 80 is connected to the glass piece 17, the connecting body 78 is fixedly connected to the connecting portion 80, the glass piece 17 and the sliding block structure 19 are integrated, and the sliding block structure 19 and the glass piece 17 can move together under the action of an external driving force. The intersecting first wall surface and second wall surface arranged on the connecting body 78 are the side surfaces of the connecting body 78 in the moving direction along the glass piece 17. The first wall surface is restricted by the first guiding portion and cooperates with the first guiding portion, the second wall surface is restricted by the second guiding portion and cooperates with the second guiding portion, and the first raised structure 82 of the first wall surface and the second raised structure 84 of the second wall surface form two intersecting restricted regions. Therefore, the trim panel structure can restrict and guide the sliding block structure 19, thereby improving the stability of the glass piece 17. When a force such as external wind pressure resistance is applied to the glass piece 17, the glass piece 17 has good resistance to external influences.

[0035] In the flat door system provided with this configuration, the sliding block structure 19 further includes a first elastic portion 94. The first elastic portion 94 is arranged on the opposite side of the connecting body 78 away from the first raised structure 82 in the protruding direction of the first raised structure 82. When the connecting body 78 is driven by an external force to move away from the trim panel 20, the first elastic portion 94 has a first elastic force that drives the connecting body 78 to move towards the trim panel 20. The acting direction of the first elastic force is parallel to the protruding direction of the first raised structure 82. The first elastic portion 94 is suitable for a slidable connection with the trim panel structure.

[0036] In the flat door system provided in this configuration, the movement of the connection body 78 is restricted by the first elastic portion 94 and the first raised structure 82. The first elastic force provided by the first elastic portion 94 is in the direction of driving the connection body 78 toward the trim panel 20, thereby promoting a tight connection between the connection body 78 and the trim panel 20, increasing the contact force between the first raised structure 82 and the first guide portion, promoting the stability of the sliding block structure 19 during movement, and ensuring the sealing performance between the seal 76 and the sliding block structure 19. The acting direction of the first elastic force is parallel to the protruding direction of the first raised structure 82. When the limiting surface provided by the first raised structure 82 is a plane, the acting direction of the first elastic force is perpendicular to the plane, thereby making it easier to position the first raised structure 82 within the first guide portion and improving the stability when the sliding block structure 19 and the glass piece 17 move together.

[0037] In the flat door system provided in this configuration, the sliding block structure 19 further includes a second elastic portion 96. The second elastic portion 96 is disposed on the opposite side of the connection body 78 away from the second raised structure 84 in the protruding direction of the second raised structure 84. When the connection body 78 is driven by an external force to move in a direction away from the trim panel 20, the second elastic portion 96 has a second elastic force that drives the connection body 78 to move toward the trim panel 20. The acting direction of the second elastic force is parallel to the protruding direction of the second raised structure 84. The second elastic portion 96 is suitable for a slidable connection with the trim panel structure.

[0038] In the sliding block structure 19 of this structure, the movement of the connection body 78 is restricted by the second elastic part 96 and the second raised structure 84. The first elastic force provided by the first elastic part 94 functions to drive the connection body 78 toward the trim panel 20, thereby promoting a tight connection between the connection body 78 and the trim panel 20, increasing the contact force between the first raised structure 82 and the first guide part, promoting the stability of the sliding block structure 19 during movement, ensuring the sealing performance between the seal 76 and the sliding block structure 19, and improving the stability when the sliding block structure 19 and the glass piece 17 move together.

[0039] In the flat door system provided in this configuration, the first elastic part 94 has an arc-shaped structure. A first cavity is formed between the first elastic part 94 and the connection body 78.

[0040] In the flat door system provided in this configuration, the first elastic part 94 has an arc-shaped structure. The arc-shaped structure generates a first elastic force that acts on the connection body 78 to approach the trim panel 20. After the sliding block structure 19 is installed in the trim panel structure, the first elastic part 94 can generate a preloading force on the connection body 78, thereby increasing the contact area between the sliding block structure 19 and the trim panel 20 and promoting the limiting ability of the first raised structure 82 by the first guide part. The space for deformation such as contraction and expansion of the arc-shaped structure is provided by the first cavity. When an external force is transmitted to the sliding block structure 19 through the glass piece 17, the arc-shaped structure utilizes its expansion and contraction to compensate for a part of the transmitted force and promote the stability of the glass piece 17.

[0041] In the flat door system provided in this configuration, at least one recess is provided in the connection part 80, and this recess is suitable for accommodating an external adhesive. The concave space area of the recess is used to accommodate the external adhesive, and the glass piece 17 and the sliding block structure 19 are fixedly connected by the external adhesive. In this way, the glass piece 17 and the sliding block structure 19 move together under the drive of an external force, ensuring the connection strength between the glass piece 17 and the sliding block structure 19.

[0042] In the flat door system provided in this configuration, at least one contact leg 86 is formed at the connection portion 80, and the contact leg 86 is suitable for fixedly connecting the glass piece 17. A plurality of contact legs 86 and the connection portion 80 together form a recess. The recess is formed by a plurality of contact legs 86 and the connection portion 80 together. The contact leg 86 protrudes outside the connection portion 80. After the glass piece 17 is fixed to the sliding block structure 19, the protruding end of the contact leg 86 abuts against the glass piece 17, and the wind pressure resistance of the glass piece 17 is transmitted to the connection portion 80 through the contact leg 86, and then transmitted to the connection body 78 through the connection portion 80, and then transmitted to the first raised structure 82 and the second raised structure 84 through the connection body 78.

[0043] In the flat door system provided in this configuration, since the outer wall surface of the glass piece 17 and the outer wall surface of the trim panel 20 are on the same plane, the connection portion between the glass piece 17 and the trim panel 20 forms a zero-step structure, thereby promoting a smooth transition between the entire glass piece 17 and the trim panel 20, reducing the wind pressure resistance coefficient at the connection portion between the glass piece 17 and the trim panel 20, and improving the stability of the glass piece 17.

[0044] In the flat door system provided in this configuration, the trim panel structure further includes a first connection plate 112, a second connection plate 114, and a bracket 116. The first connection plate 112 and the second connection plate 114 are arranged on the same side of the trim panel 20. The first connection plate 112 and the second connection plate 114 are fixedly connected to the trim panel 20. The bracket 116 is arranged between the trim panel 20 and the first connection plate 112. The bracket 116 is connected to the first connection plate 112. The bracket 116 includes a mounting plate 118 and a limiting plate 120. The mounting plate 118 is arranged between the trim panel 20 and the first connection plate 112. The mounting plate 118 is detachably connected to the first connection plate 112. The limiting plate 120 is fixedly connected to the mounting plate 118. The limiting plate 120 is bent to form a first guide portion and a second guide portion.

[0045] In the flat door system provided in this configuration, the bracket 116 is installed by the cooperation of the first connection plate 112 and the trim panel 20. The second connection plate 114 forms a support portion of the first connection plate 112, enabling the first connection plate 112 and the bracket 116 to be tightly connected. The mounting plate 118 and the first connection plate 112 are detachably connected, effectively improving the convenience of installation and removal between the bracket 116 and the first connection plate 112. By bending the limiting plate 120 to form a first guide portion and a second guide portion, the first raised structure 82 and the second raised structure 84 are in position-limiting cooperation with the limiting plate 120 via the seal assembly 74, and the sliding block structure 19 and the glass piece 17 slide along the extension direction of the limiting plate 120. The limiting plate 120 determines the movement displacement of the sliding block structure 19 and ensures the positioning of the sliding block structure 19 and the glass piece 17 on the trim panel structure.

[0046] As an alternative embodiment of this configuration, the limiting plate 120 includes a first limiting wall and a second limiting wall arranged to intersect each other. The first limiting wall is suitable for sliding against the first raised structure 82. The second limiting wall is suitable for sliding against the second raised structure 84. The structures of the first limiting wall and the second limiting wall can be specifically configured according to the limiting regions of the first raised structure 82 and the second raised structure 84. The first limiting wall and the second limiting wall can be arranged to be planar. The limiting regions on the first raised structure 82 and the second raised structure 84 are planar. The limiting surface of the first raised structure 82 is in surface contact with the first limiting wall, and the limiting surface of the second raised structure 84 is in surface contact with the second limiting wall.

[0047] As an alternative embodiment of this configuration, the mounting plate 118 is connected to the first connection plate 112 by a connection piece 122. The connection piece 122 is a screw fastener. The connection piece 122 passes through the mounting plate 118 and is connected to the first connection plate 112. The assembly between the bracket 116 and the first connection plate 112 is facilitated by the connection piece 122.

[0048] The flat door system provided in this configuration further includes a seal 76. The seal 76 is provided integrally. The seal 76 is suitable for contacting, abutting, and sliding against the first raised structure 82 and the second raised structure 84. The trim panel structure and the sliding block structure 19 are arranged at a distance. The seal 76 is arranged between the trim panel structure and the sliding block structure 19. Since the trim panel structure and the glass piece 17 are arranged at a distance, the seal 76 is arranged between the trim panel structure and the glass piece 17. The seal 76 is fixedly connected to the trim panel structure, and the seal 76 is slidably connected to the glass piece 17.

[0049] In the flat door system provided with this configuration, by disposing the seal 76 between the trim panel structure and the glass piece 17, the gap between the trim panel structure and the glass piece 17 is eliminated, preventing external fluids such as air flow and rainwater from entering the flat door system. Thus, the airtightness of the flat door system is ensured. By disposing the seal 76 between the trim panel structure and the sliding block structure 19, the gap between the trim panel structure and the sliding block structure 19 is filled, ensuring the sliding contact seals between the first guide portion and the first limiting portion, and between the second guide portion and the second limiting portion. Thereby, the connection strength of the sliding block structure 19, the seal 76, and the trim panel structure is improved, and the stability of the glass piece 17 during movement is promoted. The vibration of the glass piece 17 under conditions such as wind pressure resistance is absorbed and compensated by the seal 76, thereby promoting the stability of the glass piece 17 after installation. The seal 76 is an integral part for ensuring the sealing ability of the entire flat door system, avoiding the gap between the seal strips after installation, and preventing the intrusion of external fluids such as air flow and rainwater.

[0050] In the flat door system provided with this configuration, the seal 76 includes a first seal portion 74, a second seal portion 100, and a third seal portion 102 that are connected in sequence. The first seal portion 74 is provided between the trim panel 20 and the glass piece 17. The first seal portion 74 is fixedly coupled to the trim panel 20. The first seal portion 74 is slidably connected to the glass piece 17. The second seal portion 100 is fixedly connected to the inner walls of the first guide portion and the second guide portion. The second seal portion 100 is fixedly connected to the limiting plate 120. The second seal portion 100 is fixedly connected to the first connection plate 112. The second seal portion 100 is slidably connected to the sliding block structure 19. The third seal portion 102 is disposed between the glass piece 17 and the first connection plate 112. The third seal portion 102 is slidably connected to the glass piece 17. The third seal portion 102 is fixedly connected to the first connection plate 112.

[0051] In the flat door system provided in this configuration, the first seal portion 74 is slidably connected to the glass piece 17. The first seal portion 74 is fixedly connected to the trim panel 20. The first seal portion 74 fills and seals the space between the trim panel 20 and the glass piece 17, preventing impurities such as rainwater and air flow from the outside from entering the flat door system. The second seal portion 100 slides with respect to the first raised structure 82, forming a seal region between the first guide portion and the first raised structure 82. The third seal portion 102 slides with respect to the second raised structure 84, forming a seal region between the second guide portion and the second raised structure 84. The third seal portion 102 slides with respect to the second raised structure 84, forming a seal region between the second guide portion and the second raised structure 84. The fourth seal portion slides with respect to the glass piece 17, and the glass piece 17 is restricted by the fourth seal portion, which is beneficial for improving the stability of the glass piece 17.

[0052] The flat door system provided in this configuration further includes a support member 110. The support member 110 is disposed within the seal 76 between the second seal portion 100 and the third seal portion 102. The support member is suitable for cooperating with the sliding operation of the first elastic portion 94. The strength of the seal 76 is strengthened by the support member 110, and the first elastic portion 94 is supported by the support member 110, which is advantageous for the stability when the sliding block structure 19 and the glass piece 17 move together. The shapes of the support member 110 and the first connection plate 112 are adapted to each other.

[0053] In the flat door system provided in this configuration, the seal 76 further includes at least one abutting portion 104. The abutting portion 104 is fixedly connected to the third seal portion 102. The abutting portion 104 is slidably connected to the glass piece 17. The glass piece 17 is restricted by the abutting portion 104, thereby promoting the sliding movement of the glass piece 17 along the extension direction of the limiting plate 120, which is beneficial for improving the movement accuracy of the glass piece 17.

[0054] In the flat door system provided in this configuration, the seal 76 further includes a hook portion 106. The hook portion 106 is fixedly connected to the third seal portion 102. The hook portion 106 hooks the first connection plate 112 and the first connection plate 112. The first connection plate 112 is connected to the second connection plate and the seal 76 by the hook portion 106. The first connection plate 112 and the second connection plate 114 form the support of the seal 76, improving the connection strength between the seal 76 and the trim panel structure, so that the seal 76 is more suitable for the sliding state between the sliding block structure 19 and the trim panel structure. It will be understood that the hook portion 106 is optional.

[0055] In the flat door system provided in this configuration, a bent portion or a hook 56 is provided at the end of the trim panel 20 away from the glass piece 17. The curved end of the bent portion 56 extends toward the glass piece 17. One side of the bent portion 56 abuts against the second connection plate 114. The end of the second connection plate 114 is connected at a position between the bent portion 56 and the first connection plate 112. The ends of the first connection plate 112 and the second connection plate 114 are fixed inside the trim panel 20 by the bent portion 56, ensuring the contact area between the trim panel 20 and the first connection plate 112, and between the first connection plate 112 and the second connection plate 114. This improves the connection strength within the trim panel structure and forms an effective support for the sliding block structure 19 inside the trim panel 20, thereby improving the stability when the sliding block structure 19 and the glass piece 17 move together.

[0056] In the flat door system provided in this configuration, the first raised structure 82 includes at least one first limiting portion, and the second raised structure 84 includes at least one second limiting portion.

[0057] In the flat door system provided in this configuration, the first limiting portion cooperates with the first guiding portion, and the second limiting portion cooperates with the second guiding portion to limit the sliding block structure 19. Therefore, the sliding block structure 19 and the glass piece 17 move together in the limiting direction, and the moving accuracy of the glass piece 17 is improved. The first raised structure 82, the second raised structure 84, and the trim panel structure contact the limiting region for limiting by the shape conformity of the first guiding portion and the second guiding portion formed particularly by the trim panel structure, facilitating the limitation and guiding between the sliding block structure 19 and the trim panel structure.

[0058] As an alternative embodiment of this configuration, the first limiting portion can be configured as a protrusion formed on the first wall surface. There may be two or more spaced-apart protrusions on the first wall surface. The protrusion slidably cooperates with the first guiding portion to provide the limiting direction of the sliding block structure 19.

[0059] As an alternative embodiment of this configuration, the second limiting portion can be configured as a protrusion formed on the second wall surface. There may be two or more spaced-apart protrusions on the second wall surface. The protrusion slidably cooperates with the second guiding portion to provide another limiting direction of the sliding block structure 19.

[0060] Referring now to FIGS. 25 - 29, according to yet another embodiment, a flash glass system (which may be referred to herein as a flat door system) includes a sliding block structure 19, a glass piece 17, and a trim panel structure. The sliding block structure 19 includes a connection structure and a restriction structure. The connection structure includes a connection body 78 and a connection portion 80. The connection body 78 is fixedly connected to the connection portion 80. The connection body 78 has a first wall surface, a second wall surface, and a third wall surface. The first wall surface and the second wall surface are arranged to intersect each other. The first wall surface is on the opposite side of the third wall surface. The second wall surface is disposed between the first wall surface and the third wall surface. The restriction structure includes a first raised portion 82 and a second raised portion 84. The first raised portion 82 is provided on the first wall surface, and the second raised portion 84 is provided at an end of the second wall surface near the third wall surface. The glass piece 17 is connected to the connection portion 80. The trim panel structure is provided on a first guide portion and a second guide portion. The first guide portion is slidably connected to the first raised portion 82, and the second guide portion is slidably connected to the second raised portion 84.

[0061] In the flat door system provided with this configuration, since the glass piece 17 is coupled to the sliding block structure 19 by a connection structure, the sliding block structure 19 and the glass piece 17 can move together under the action of an external driving force. The first guide portion cooperates with the first limiting portion to limit the position, and the second guide portion cooperates with the second limiting portion to limit the position, thereby forming two limiting regions for limiting the sliding block structure 19. The trim panel structure can limit and guide the movement of the sliding block structure 19 and the glass piece 17, thereby improving the movement accuracy of the glass piece 17 in the flat door system. By disposing the first raised portion 82 on the first wall surface of the connection body 78 and disposing the second raised portion 84 on the second wall surface of the connection body 78, the second raised portion 84 is located at the end of the second wall surface close to the third wall surface, and the limiting region determined by the first raised portion 82 and the second raised portion 84 has an appropriate (reasonable) interval. Thus, sufficient contact space is ensured between the first raised portion 82 and the first guide portion, and between the first raised portion 82 and the second guide portion. The sliding block structure 19 and the glass piece 17 can move according to the sliding and guiding space provided by the trim panel structure, and the stability of the glass piece 17 is improved.

[0062] As an alternative embodiment of this configuration, the first limiting portion can be configured as a protrusion formed on the first wall surface. There may be two or more spaced-apart protrusions on the first wall surface. The protrusions cooperate slidably with the first guide portion to provide a limiting direction for the sliding block structure 19.

[0063] As an alternative embodiment of this configuration, the second limiting portion can be configured as a protrusion formed on the second wall surface. There may be two or more spaced-apart protrusions on the second wall surface. The protrusions cooperate slidably with the second guide portion to provide another limiting direction for the sliding block structure 19.

[0064] In the flat door system provided with this configuration, the limiting structure further includes an elastic part 96. The elastic part 96 is arranged on the opposite side of the connection body 78 away from the second raised part 84 in the protruding direction of the second raised part 84. When the connection body 78 is driven by an external force to move away from the trim panel 20, the elastic part 96 has an elastic force that drives the connection body 78 to move towards the trim panel 20. The acting direction of the elastic force is parallel to the protruding direction of the second raised part 84. The elastic part 96 is suitable for a slidable connection with the trim panel 20 structure.

[0065] In the flat door system provided with this configuration, the movement of the connection body 78 is restricted by the cooperation of the elastic part 96 and the second raised part. The elastic force provided by the elastic part 96 is in the direction of driving the connection body 78 towards the trim panel 41, thereby promoting a tight connection between the connection body 78 and the trim panel 41. The contact force between the first raised part 82 and the first guide part for restricting the position increases, thereby promoting the stability of the sliding block structure 19 during movement and facilitating the reduction of the gap between the sliding block structure 19, the seal 5, and the trim panel structure. Thereby, the sealing performance between the seal 76 and the sliding block structure 19 is ensured, and the sealing effect of the seal 76 is improved. The elastic force of the elastic part 96 acts in a direction parallel to the protruding direction of the second raised part 84. When the limiting surface provided by the first raised structure is a plane, the acting direction of the first elastic force is perpendicular to that plane. The movement of the sliding block structure 19 in the extension direction of this plane is restricted by both the second raised part 84 and the elastic part 96, and the guiding and positioning between the sliding block structure 19 and the trim panel structure are improved, thereby improving the stability when the sliding block structure 19 and the glass piece 17 move together.

[0066] In the flat door system provided with this configuration, the elastic part 96 has an arc-shaped structure. A free space is provided between the arc-shaped structure and the connection main body 78. The free space is suitable for accommodating deformations such as expansion and contraction of the arc-shaped structure. An elastic force is generated by the arc-shaped structure, and the connection main body 78 moves toward the trim panel 41. After the sliding block structure 19 is attached to the trim panel structure, the elastic part 96 generates a pre-tightening force on the connection main body 78, promoting a tight connection between the sliding structure and the trim panel structure. After the arc-shaped structure is deformed, the contact area between the elastic part 96 and the trim panel structure increases. By increasing the contact area between the sliding block structure 19 and the trim panel 41, the ability of the first guide part to limit the position of the first raised structure is improved. The first cavity provides a space in advance for the deformation of the arc-shaped structure. When an external force is transmitted to the sliding block structure 19 through the glass piece 17, a part of the transmitted force is compensated by utilizing the expansion and contraction of the arc-shaped structure, promoting the stability of the glass piece 17.

[0067] In the flat door system provided with this configuration, the connection main body includes a cavity part 111. The elastic part 96 is configured in the cavity part 111. A cavity is formed in the cavity part 111 so as not to prevent the deformation of the elastic part 96. The cavity part 111 has a concave structure. Both ends of the elastic part 96 are formed in the cavity part 111.

[0068] In the flat door system provided with this configuration, the connection structure is inclined with respect to the wall surface of the glass piece 17. The end of the connection structure of the connection main body 78 away from the glass piece 17 extends to the outer edge of the glass piece 17, and the trim panel structure constitutes a support part for the middle region of the glass piece 17. It is advantageous for improving the limiting and supporting ability of the trim panel structure with respect to the glass piece 17, promoting the transmission and dispersion of external forces, and promoting the dispersion of forces to the first limiting part and the second limiting part. The force is further resisted and absorbed by the trim panel structure, achieving the purpose of improving the stability of the glass piece 17.

[0069] In the flat door system provided in this configuration, at least one recess is provided in the connection portion 80. The recess is suitable for accommodating an external adhesive. The glass piece 17 and the sliding block structure 19 are fixedly connected by the external adhesive, ensuring the connection strength between the glass piece 17 and the sliding block structure 19. Therefore, when an external driving force acts on the glass piece 17 or the sliding block structure 19, the glass piece 17 and the sliding block structure 19 move together within the space provided by the trim panel structure.

[0070] In the flat door system provided in this configuration, at least one contact leg 86 is formed on the connection portion 80. The contact leg 86 is suitable for connecting the glass piece 17. The plurality of contact legs 86 and the connection portion 80 together form a recess. The recess is formed by the plurality of contact legs 86 and the connection portion 80 together. The contact leg 86 protrudes outside the connection portion 80. After the glass piece 17 is fixed to the sliding block structure 19, the protruding end of the contact leg 86 abuts against the glass piece 17, and the wind pressure resistance of the glass piece 17 is transmitted to the connection portion 80 through the contact leg 86, and then transmitted to the trim panel structure through the first limiting portion, the second limiting portion, and the elastic portion 96.

[0071] In the flat door system provided in this configuration, the trim panel structure further includes a guide bracket. The guide bracket is fixedly connected to the trim panel 20. The guide bracket includes a first connection plate or branch portion 38, a second connection plate or base 42, and a third connection plate or branch portion 40. The first connection plate 38 is fixedly connected to the trim panel 20. The first connection plate 38 is suitable for sliding connection with the second raised portion 84. The second connection plate 42 is fixedly connected to the same side of the first connection plate 38 of the trim panel 20. The third connection plate 40 is fixedly connected to the same side of the second connection plate 42 of the first connection plate 38. The third connection plate 40 is suitable for sliding connection with the elastic portion 94. The trim panel 20, the first connection plate 38, the second connection plate 42, and the third connection plate 40 together form a first guide portion and a second guide portion.

[0072] In the flat door system provided in this configuration, the first guide portion and the second guide portion are formed by the cooperation of the guide bracket and the trim panel 20. The guide bracket slidably cooperates with the first raised portion 82 and the second raised portion 84, and the guide bracket and the trim panel 20 constitute the restriction and support for the sliding block structure 19. Thus, the sliding block structure 19 and the glass piece 17 slide along the extension direction of the restriction plate. The restriction plate determines the displacement of the sliding block structure 19 and ensures the positioning of the sliding block structure 19 and the glass piece 17 on the trim panel 20 structure.

[0073] The flat door system provided in this configuration further includes a seal 76. The seal 76 is provided integrally. The seal 76 is suitable for slidably abutting against the first raised portion 82 and the second raised portion 84. The trim panel 20 structure and the sliding block structure 19 are spaced apart. The seal 76 is disposed between the trim panel 20 structure and the sliding block structure 19. The trim panel 20 structure and the glass piece 17 are spaced apart. The seal 76 is disposed between the trim panel 20 structure and the glass piece 17. The seal 76 is fixedly connected to the trim panel 20 structure. The seal 76 is slidably connected to the glass piece 17.

[0074] In the flat door system provided in this configuration, the gap between the trim panel 20 structure and the glass piece 17 is eliminated by the seal 76, preventing external fluids such as air flow and rainwater from entering the flat door system, and ensuring the airtightness of the flat door system. The seal 76 fills the gap between the trim panel 20 structure and the sliding block structure 19, thereby facilitating the sliding contact seal between the first guide portion and the first limiting portion and the sliding contact seal between the second guide portion and the second limiting portion, improving the connection strength of the sliding block structure 19, the seal 76, and the trim panel 20 structure, and promoting the stability of the glass piece 17 in the moving state. The vibration of the glass piece 17 under conditions such as wind pressure resistance is absorbed and compensated by the seal 76, thereby promoting the stability of the glass piece 17 after installation. The seal 76 is an integral part for ensuring the sealing ability of the entire flat door system, avoiding the gap between the seal strips after installation, and avoiding the intrusion of external fluids such as air flow and rainwater.

[0075] In the flat door system provided with this configuration, the trim panel 20 structure includes a trim panel 20 slidably connected to the sliding block structure 19. The outer wall surface of the glass piece 17 is flush with the outer wall surface of the trim panel 20. By arranging the glass piece 17 and the trim panel 20 on the same plane, the connection portion between the glass piece 17 and the trim panel 20 forms a zero-step structure, thereby promoting a smooth transition between the entire glass piece 17 and the trim panel 20, which is advantageous for reducing the wind pressure resistance coefficient of the flat door system, thereby enhancing the stability of the glass piece 17.

[0076] In the flat door system provided with this configuration, the first connection plate 38 and the third connection plate 40 are arranged parallel and spaced apart, and the first connection plate 38 and the second connection plate 42 are arranged perpendicular to each other, so that the first guide portion of the trim panel 20 structure is perpendicular to the second guide portion. Thus, the first limiting portion is perpendicular to the second limiting portion, and the trim panel 20 structure restricts the sliding block structure 19 in two directions perpendicular to each other. The external force is dispersed and transmitted by the first limiting portion and the second limiting portion perpendicular to each other.

[0077] In the flat door system provided with this configuration, the seal 76 includes a first seal portion 72, a second seal portion 100, and a third seal portion 102 connected in sequence. The first seal portion 72 is disposed between the trim panel 20 and the glass piece 17. The first seal portion 72 is fixedly connected to the trim panel 20. The first seal portion 72 is slidably connected to the glass piece 17. The second seal portion 100 is fixedly connected to the inner wall of the guide portion. The second seal portion 100 is slidably connected to the sliding block structure 19. The third seal portion 102 is disposed between the glass piece 17 and the trim panel 20 structure. The third seal portion 102 is slidably connected to the glass piece 17, and the third seal portion 102 is fixedly connected to the trim panel 20 structure.

[0078] In the flat door system provided in this configuration, the first seal portion 72 fills and seals the gap between the trim panel 20 and the glass piece 17 to prevent external impurities such as rainwater and air flow from entering the flat door system. The first seal portion 72 is slidably connected to the glass piece 17. The first seal portion 72 is fixedly connected to the trim panel 20. The first seal portion 72 cooperates with the sliding trim panel 20 structure to limit and guide the sliding block structure 19. The second seal portion 100 is disposed on the inner walls of the first guide portion and the second guide portion. The second seal portion 100 is slidably abutted against the first limiting portion and the second limiting portion to form a seal area in the sliding space between the trim panel 20 structure and the sliding structure. The third seal portion 102 is slidably abutted against the glass piece 17, and the position of the glass piece 17 is limited by the third seal portion 102, which is beneficial to improving the stability of the glass piece 17.

[0079] In the flat door system provided in this configuration, the seal 76 further includes at least one abutting portion 104. The abutting portion 104 is fixedly connected to the trim panel 20 structure. The abutting portion 104 is slidably connected to the glass piece 17. Since the position of the glass piece 17 is limited by the abutting portion 104, the sliding of the glass piece 17 along the extension direction of the guide bracket is promoted, which is beneficial to improving the movement accuracy of the glass piece 17. At the same time, this improves the connection strength between the seal 76 and the trim panel 20 structure, thereby making the seal 76 more suitable for the sliding state between the sliding block structure 19 and the trim panel 20 structure.

[0080] In the flat door system provided in this configuration, the trim panel 20 structure further includes a first mounting plate 112 and a second mounting plate 114. The first mounting plate 112 is detachably connected to the guide bracket. The first mounting plate 112 is fixedly connected to the trim panel 20. The first mounting plate 112 is suitable for abutting and connecting to the seal 76. The second mounting plate 114 is disposed between the trim panel 20 and the second mounting plate 114. The first mounting plate 114 is fixedly connected to the second mounting plate 114. The seal 76 is supported by the first mounting plate 112, and the seal 76 is fixed between the first mounting plate 112 and the glass piece 17. The ends of the first mounting plate 112 and the second mounting plate 114 are joined in surface contact with each other. The connection strength of the trim panel 20 is ensured by the contact between the two, thereby promoting the stability when the sliding block structure 19 and the glass piece 17 move together.

[0081] In the flat door system provided in this configuration, the trim panel 20 structure further includes a connection bracket 108. The connection bracket 108 is connected between the trim panel 20 and the first connection plate 38. The connection bracket 108 is disposed on the same side as the first connection plate 38 of the seal 76. The connection bracket 108 is fixedly connected to the trim panel 20. The connection bracket 108 is fixedly connected to the first connection plate 38 and is orthogonal to the first connection plate 38. The connection bracket 108 forms an auxiliary support for the first connection plate 38 and at the same time improves the connection strength between the guide bracket and the trim panel 20.

[0082] In the flat door system provided in this configuration, the guide bracket is detachably connected to the first mounting plate 112 by a locking member 124 to ensure the connection strength between the guide bracket and the first mounting plate 112. When an external force is applied to the glass piece 17, the force is transmitted to the first mounting plate 112 and the second mounting plate 114 through the guide bracket that absorbs and resists the external force.

[0083] In the flat door system provided in this configuration, the bent portion or hook 56 is provided at the end of the trim panel 20 away from the glass piece 17. The curved end of the bent portion 56 extends toward the glass piece 17. One side of the bent portion 56 abuts against the second mounting plate 114. The end of the second mounting plate 114 is connected and disposed between the bent portion 56 and the first mounting plate 112.

[0084] Here, referring to FIGS. 30 to 33, according to a further alternative embodiment, a flush glass system (which may be referred to as a flat door system herein) includes a flat door system having a sliding block structure 19, a glass piece 17, and a trim panel structure. It will be understood that the trim panel structure may be the trim panel 20 in some configurations, or any component of the trim panel 20 such as the exterior member 32. The sliding block structure 19 includes a body portion 78, a first limiting portion 82 and a second limiting portion 84 fixedly connected to the body portion 78. The first limiting portion 82 is disposed at a first angle with respect to the second limiting portion 84. The glass piece 17 is fixedly connected to the body portion 78. The trim panel structure is provided with a first guide portion and a second guide portion. The first guide portion is slidably connected to the first limiting portion 82, and the second guide portion is slidably connected to the second limiting portion 84. The glass piece 17 is slidably disposed together with the trim panel structure by using the sliding block structure 19.

[0085] In the flat door system provided by this configuration, the main body portion 78 is connected to the glass piece 17, and the main body portion 78 and the glass piece 17 move together under the action of an external driving force. The movement of the main body portion 78 is restricted by the first restricting portion 82 and the second restricting portion 84. The first restricting portion 82 slidably cooperates with the first guide portion of the trim panel structure. The second restricting portion 84 slidably cooperates with the second guide portion of the trim panel structure. The first restricting portion 82 is arranged at a first angle with respect to the second restricting portion 84, and the first restricting portion 82 and the second restricting portion 84 restrict the main body portion 78 in two intersecting directions, and strengthen the restriction and guidance of the movement of the glass piece 17 by the sliding block structure 19. Thus, since the glass piece 17 and the sliding block structure 19 move in the restriction direction determined by the first guide portion and the second guide portion, the stability of the glass piece 17 during movement is effectively improved. When an external wind pressure resistance acts on the glass piece 17, the glass piece 17 transmits a force to the main body portion 78 of the sliding block structure 19. The wind pressure resistance is shared by the first restricting portion 82 and the second restricting portion 84. The first restricting portion 82 transmits the force to the first guide portion, and the second restricting portion 84 transmits the force to the second guide portion. Next, the force is transmitted to the trim panel 20 through the first guide portion and the second guide portion. The sliding block structure 19 cooperates with the trim panel structure to reduce the wind pressure resistance, thereby improving the stability of the glass piece 17 during movement.

[0086] In the flat door system provided by this configuration, the first restricting portion 82 is arranged at a first angle with respect to the second restricting portion 84, and the first restricting portion 82 and the second restricting portion 84 can restrict the main body portion 78 in two intersecting directions, and can strengthen the restriction and guidance of the movement of the glass piece 17 by the sliding block structure 19.

[0087] In the flat door system provided by this configuration, the first angle between the first limiting portion 82 and the second limiting portion 84 is arranged between 30° and 150°. The angle formed by the first guiding portion and the second guiding portion is arranged to coincide with the first angle. The first limiting portion 82 cooperates slidably with the first guiding portion, and the second limiting portion 84 cooperates slidably with the second guiding portion, whereby the sliding block structure 19 can slide according to the space provided by the trim panel structure.

[0088] As an alternative embodiment of this configuration, the first limiting portion 82 is arranged to be perpendicular to the second limiting portion 84. The limiting surface provided by the first limiting portion 82 can be arranged to be parallel to the wall surface of the glass piece 17. The limiting surfaces provided by the two limiting portions 84 can be arranged to be perpendicular to the wall surface of the glass piece 17, so that when the glass piece 17 transmits an external force to the sliding block structure 19, the first limiting portion 82 and the second limiting portion 84 that are perpendicular to each other decompose against the external force and finally transmit it to the trim panel structure, which is beneficial to improving the stability of the glass piece 17 and reducing the influence of the external force on the integral movement of the glass piece 17 and the sliding block structure 19.

[0089] In the flat door system provided by this configuration, at least one first limiting protrusion 88 is provided on the outer wall of the first limiting portion 82. The first limiting protrusion 88 is slidably arranged within the first guiding portion. At least one second limiting protrusion 90 is provided on the outer wall surface of the second limiting portion 84. The second limiting protrusion 90 is slidably arranged within the second guiding portion.

[0090] In the flat door system provided in this configuration, the first limiting protrusion 88 is formed on the outer wall surface of the first limiting portion 82. The limiting surface between the first limiting portion 82 and the first guiding portion can be determined by the first limiting protrusion 88. The first limiting protrusion 88 slides relative to the first guiding portion, the first limiting portion 82 slides within the first guiding portion, and the first limiting portion 82 and the first guiding portion form a limiting surface for the glass piece 17. The second limiting protrusion 90 is formed on the outer wall surface of the second limiting portion 84. Another limiting surface between the second limiting portion 84 and the second guiding portion can be determined by the second limiting protrusion 90. The second limiting protrusion 90 slides relative to the second guiding portion, the second limiting portion 84 slides within the second guiding portion, and the second limiting portion 84 and the second guiding portion form another limiting surface for the glass piece 17. The extending directions of the two limiting surfaces are parallel to the moving direction of the glass piece 17, ensuring that the glass piece 17 moves along the extending directions of the first guiding portion and the second guiding portion. The stability of the movement of the glass piece 17 is improved by the first limiting protrusion 88 and the second limiting protrusion 90. The shapes of the two limiting surfaces are specially configured according to the connections between the first limiting protrusion 88 and the first guiding portion, and between the second limiting protrusion 90 and the second guiding portion respectively.

[0091] As an alternative embodiment of this configuration, the second limiting protrusion 90 is symmetrically arranged with respect to the second raised portion. The height of the second limiting protrusion 90 in the direction perpendicular to the extending surface of the second raised portion varies. This is adjusted according to the thickness of the seal 76 arranged between the second raised portion and the second guiding portion, sufficiently reducing the sliding clearance, ensuring good sealing performance between the sliding block structure 19 and the trim panel 20, and meeting the requirements of reasonable sliding resistance.

[0092] In the flat door system provided with this configuration, at least one recess is provided in the main body portion 78. The recess is suitable for accommodating an external adhesive. The space provided by the recess is used to accommodate the external adhesive. The glass piece 17 is joined to the sliding block structure 19 by an external adhesive, and the glass piece 17 and the sliding block structure 19 move together under the drive of an external force, ensuring the connection strength between the glass piece 17 and the sliding block structure 19.

[0093] In the flat door system provided with this configuration, at least one contact leg 86 is provided in the main body portion 78. The contact leg 86 is suitable for connecting to the glass piece 17. A plurality of contact legs 86 and the main body portion 78 together form a recess. The recess is formed by a plurality of contact legs 86 and the main body portion 78 together. The contact legs 86 are arranged to protrude toward the outside of the main body portion 1. After the glass piece 17 is fixed to the sliding block structure 19, the protruding end of the contact leg 86 abuts against the glass piece 17, and the wind pressure resistance of the glass piece 17 is transmitted to the main body portion 78 through the contact leg 11, and then is transmitted to the first limiting portion 82 and the second limiting portion 84 through the main body portion 1.

[0094] In the flat door system provided with this configuration, the sliding block structure 19 is a strip-shaped structure. The sliding block structure 19 slides according to the space provided by the trim panel structure. The main body portion 1, the first limiting portion 82, and the second limiting portion 84 extend along the sliding direction. A plurality of first limiting protrusions 88 are spaced apart and arranged on the first limiting portion 82, and a plurality of first limiting protrusions 88 are spaced apart and arranged on the second limiting portion 84, thereby forming a plurality of contact limiting surfaces between the sliding block structure 19 and the trim panel structure, ensuring an appropriate sliding resistance.

[0095] In the flat door system provided in this configuration, the sliding block structure 19 is fixedly connected by the glass piece 17, and the glass piece 17 and the sliding block structure 19 can move together under the drive of an external force. Due to the limiting effect between the first limiting part 82 and the first guiding part, and the limiting effect between the second limiting part 84 and the second guiding part, the glass piece 17 and the sliding block structure 19 move in the limiting direction determined by the first guiding part and the second guiding part, so the movement accuracy of the glass piece 17 is improved, and the movement stability of the glass piece 17 is improved.

[0096] As an alternative embodiment of this configuration, two or more sliding block structures are provided. The sliding block structures are arranged perpendicular to the side surface of the glass piece 17 and are fixedly connected thereto. The sliding block structures are driven by an external driving force and displace within the trim panel structure, and the glass piece 17 moves up and down by the sliding block structure 19.

[0097] In the flat door system provided in this configuration, the flat door system further includes a seal 76. The seal 76 is provided integrally. The seal 76 is arranged on the first guiding part and the second guiding part. The seal 76 abuts against the first limiting part 82 and the second limiting part 84. The trim panel structure and the sliding block structure 19 are spaced apart. The seal 76 is arranged between the trim panel structure and the sliding block structure 19. The trim panel structure and the glass piece 17 are spaced apart. The seal 76 is arranged between the trim panel structure and the glass piece 17. The seal 76 is fixedly connected to the trim panel structure. The seal 76 is slidably connected to the glass piece 17.

[0098] In the flat door system provided in this configuration, by disposing the seal 76 between the trim panel structure and the glass piece 17, the gap between the trim panel structure and the glass piece 17 is sealed, preventing external fluids such as air flow and rainwater from entering the flat door system, thereby ensuring the airtightness of the flat door system. By disposing the seal 76 between the trim panel structure and the sliding block structure 19, the gap between the trim panel structure and the sliding block structure 19 is filled, and it is guaranteed that the first guide portion slidably and airtightly abuts against the first limiting portion 82, and the second guide portion slidably and airtightly abuts against the second limiting portion 84. In this way, the connection strength of the sliding block structure 19, the seal 76, and the trim panel structure is improved. The stability during the movement of the glass piece 17 is improved. The seal 76 can absorb and compensate for the force applied to the glass piece 17 in an environment such as wind pressure resistance, which is beneficial for improving the stability of the glass piece 17. The seal 76 is integrally provided, ensuring the sealing performance of the entire flat door system, avoiding the gaps between the plurality of seal strips after installing these seal strips, and avoiding the intrusion of external fluids such as air flow and rainwater.

[0099] In the flat door system provided with this configuration, the trim panel structure includes a trim panel 20 having a first connection plate or exterior member 32, a second connection plate or branch portion 38, a third connection plate or base 42, a fourth connection plate 43, and a fifth connection plate or branch portion 40. The first connection plate 32 and the third connection plate 42 are arranged parallel and spaced apart. The second connection plate 38, the fourth connection plate 43, and the fifth connection plate 40 are arranged parallel and spaced apart in order. The second connection plate 38 is fixedly connected between the first connection plate 32 and the third connection plate 42 and is orthogonal to them. The fourth connection plate 43 and the fifth connection plate 40 are fixedly connected to the same side of the third connection plate 42 close to the first connection plate 32. The first connection plate 32, the second connection plate 38, the third connection plate 42, and the fourth connection plate 43 form a first guide portion. The third connection plate 42, the fourth connection plate 43, and the fifth connection plate 40 form a second guide portion. Since the first guide portion restricts the sliding movement of the first limiting portion 82 and the second guide portion restricts the sliding movement of the second limiting portion 84, the sliding structure slides within the space provided by the trim panel structure.

[0100] As an alternative embodiment of this configuration, the first connection plate 32 and the second connection plate 38 are joined together. The first connection plate 32 is the outer trim panel 20 of the door, and the outer trim panel 20 needs to have good mechanical strength to withstand external impact forces.

[0101] As an alternative embodiment of this configuration, the first connection plate 32, the second connection plate 38, the third connection plate 42, the fourth connection plate 43, and the fifth connection plate 40 are manufactured by an integral molding process. This is advantageous for facilitating the installation of the entire trim panel structure. Since the molding strength of each connection plate is constant, the service life is stable.

[0102] In the flat door system provided with this configuration, the outer wall surface of the first connection plate 32 is flush with the outer wall surface of the glass piece 17. The outer wall surface of the glass piece 17 is flush with the outer wall surface of the first connection plate 32. Thus, the connection portion between the glass piece 17 and the first connection plate 32 forms a zero-step structure, thereby facilitating a smooth transition between the entire glass piece 17 and the first connection plate 32, reducing the wind pressure resistance coefficient at the connection portion between the glass piece 17 and the first connection plate 32, and improving the stability of the glass piece 17.

[0103] In the flat door system provided with this configuration, the seal 76 includes a first seal portion 72, a second seal portion 100, a third seal portion 102, and a fourth seal portion 104 that are connected in sequence. The first seal portion 72 is disposed between the first connection plate 32 and the glass piece 17. The first seal portion 72 is fixedly connected to the first connection plate 32. The first seal portion 72 is slidably connected to the glass piece 17. The second seal portion 100 is fixedly disposed on the inner wall of the first guide portion. The second seal portion 100 is adapted to be connected to the first limiting portion 82. The third seal portion 102 is fixedly disposed on the inner wall of the second guide portion. The third seal portion 102 is adapted to be slidably connected to the second limiting portion 84. The fourth seal portion 104 is slidably disposed on the glass piece 17.

[0104] In the flat door system provided with this configuration, the gap between the first connection plate 32 and the glass piece 17 is filled and sealed by the first seal portion 72, preventing external rainwater, air flow, and other impurities from entering the flat door system. The second seal portion 100 slidably abuts against the first limiting portion 82, forming a seal area between the first guide portion and the first limiting portion 82. The third seal portion 102 slidably abuts against the second limiting portion 84, forming a seal area between the second guide portion and the second limiting portion 84. The fourth seal portion 104 slidably abuts against the glass piece 17, and the glass piece 17 is restricted by the fourth seal portion 104, which is beneficial for improving the stability of the glass piece 17. Through the cooperation of the first connection plate 32, the second connection plate 38, the third connection plate 42, the fourth connection plate 43, and the fifth connection plate 40, the first seal portion 72, the second seal portion 100, and the third seal portion 102 are integrated to limit the sliding structure and the integrated movement of the glass piece 17.
