Description

Technical Field

[0001] This disclosure relates to a flush door for vehicles with an integrated track frame and a method for assembling the same. Background Technology

[0002] Door glass is installed on doors 110F and 110R of vehicle 100 for the purpose of light transmission and ventilation of the vehicle.

[0003] In vehicles, such as Figure 1 As shown, an example is illustrated where the door glass 121 is installed without a step between the door glass 121 and the decorative element 127. Figure 1 On line AA, door glass 121 and decorative piece 127 are mounted on the same surface without any steps.

[0004] Door glass 121 can have, for example Figure 2 The cross-sectional structure shown. Figure 2 This is a cross-sectional view of the rear end of the front door 110F. A space for mounting a glass guide channel is formed inside the door frame 113. The glass guide channel is configured with an inner lip 124a supporting the inner surface of the door glass 121 and an outer lip 124b supporting the end portion of the door glass 121, and the glass guide channel is fastened to the space formed inside the door frame 113. At the end portion of the door glass 121, a slider 122 is attached to the inner surface of the door glass 121. The slider 122 guides the vertical movement of the door glass 121 while moving along the height direction of the vehicle 100 within a track 114 separately formed on the door frame 113.

[0005] The decorative element 127 on the outer surface of the door frame 113 is fastened to the outer side of the door frame 113. An inner panel 111 is provided on the inner side of the door frame 113, and a door trim 125 is installed on the inner panel 111 to decorate the inner panel 111.

[0006] When the door glass 121 is installed on the door frame 113, the slider 122 is attached to the inner surface of the door glass 121, and the end portion of the slider 122 slides in the door frame 113, so that the door glass 121 and the decorative piece 127 are at the same height, that is, at the same surface without any steps.

[0007] Because there is no step between the door glass 121 and the trim piece 127, it has the following advantages: improved vehicle appearance and no noise caused by the step during driving.

[0008] However, in door 110F, the track 114 that guides the up and down movement of door glass 121 is applied as a separate structure to door frame 113, or although not shown in the figures, the separate track is fastened to allow track 114 to restrict the periphery of slider 122, thereby guiding the up and down movement of slider 122.

[0009] However, because this structure has a track 114 for guiding the vertical movement of the slider 122 as a separate structure, there is a problem with difficulty in assembly. For example, when the track 114 is integrally formed with the door frame 113, the track 114 should be operated in the vertical direction of the door glass 121 to which the slider 122 is attached, and therefore assembly is not easy.

[0010] Furthermore, due to the space inside the track 114 of the door frame 113, it is not easy to apply components to strengthen the rigidity of the door 110F. Summary of the Invention

[0011] This disclosure relates to a flush door with an integrated track frame for vehicles and a method for assembling the same.

[0018] A locking portion may be formed on the door frame, which protrudes outward toward the outside of the vehicle and restricts the movement of the sliding member in the longitudinal direction of the vehicle.

[0019] A tensioning portion can be formed, which is configured to elastically support the slider between the slider and the door frame when the slider moves up and down.

[0020] The tensioning portion may include: a first tensioning portion formed to protrude from the main body portion in the width direction of the vehicle to elastically support the main body portion in the width direction; and a second tensioning portion formed to protrude from the main body portion in the longitudinal direction of the vehicle to elastically support the main body portion in the longitudinal direction.

[0021] The inner panel can be installed on the door frame from the inside of the vehicle.

[0022] A flush door may also include a vertical beam formed between the door frame and the inner panel along the vertical direction of the vehicle.

[0023] A vertical beam may be disposed between the locking portion of the door frame and the inner panel, the locking portion being configured to restrict the movement of the slider in the longitudinal direction of the vehicle and to restrict the movement of the inner guide portion configured to accommodate the slider in the longitudinal direction of the vehicle.

[0024] Vertical beams can be made hollow.

[0025] A flush door may also include: an inner cover, fixed to the inside of the vehicle within an inner panel; and a weatherstripping, fixed to the inner panel and sealing the gap between the door and another door positioned along the longitudinal direction of the vehicle.

[0026] An entry portion, which is formed in an annular shape, may be formed at the upper and lower ends of the slider in the height direction of the vehicle.

[0027] Flush doors may also include a decorative cover that is fastened to the outer surface of the decorative panel and forms a continuous surface with the door glass.

[0028] A flush door may also include: an inner lip of a glass guide channel, fixed to the end portion of the door frame and sealing the gap between the door frame and the door glass; and an outer lip of a glass guide channel, fixed to the end portion of a decorative panel and sealing the gap between the end portion of the decorative panel and the end portion of the door glass.

[0029] A flush door may also include: an inner cover, fixed to the inside of the vehicle within the door frame; and a weatherstripping, fixed to the inner cover and sealing the gap between the door and another door positioned along the longitudinal direction of the vehicle.

[0030] Meanwhile, the assembly method of a flush door for a vehicle with an integrated track door frame according to an embodiment of the present disclosure includes: a temporary door panel assembly operation, in which a main door panel assembly is assembled by arranging a vertical beam between the door frame and the inner panel and fastening the door frame, the vertical beam and the inner panel; a door panel assembly completion operation, in which the door panel assembly is completed by assembling an outer door panel on the outside of the main door panel assembly; a door glass installation operation, in which the door glass is installed such that a sliding member mounted on the door glass is disposed on an inner guide portion formed on the door frame; and a decorative member assembly operation, in which the door frame is assembled to a decorative member to cover the outside of the sliding member.

[0031] Both door glass installation and trim assembly operations can include assembling the door glass and trim components in the width direction of the vehicle.

[0032] The method may also include: a glass guide groove installation operation, in which the inner lip of the glass guide groove is installed onto the door panel assembly between the completion of the door panel assembly operation and the door glass installation operation.

[0033] According to the flush door for vehicles with an integrated track frame (having the above-described structure) and its assembly method according to embodiments of the present disclosure, the sliding member can be easily assembled by limiting the periphery of the sliding member mounted on the door glass by the space formed between the door frame and the decorative panel, rather than by a separate track, to guide the vertical movement of the sliding member. When a track is used, the sliding member should be assembled in the vertical direction; however, when the track is formed to surround the periphery of the sliding member between the door frame and the decorative panel, the door can be assembled only in the width direction of the vehicle, and therefore assembly can be easy.

[0034] Furthermore, because no tracks are used, the interior space is larger, and vertical beams formed in the vertical direction can be installed in this space, thereby increasing rigidity. Attached Figure Description

[0044] In the following, a flush door for a vehicle with an integrated track frame and a method for assembling the same, according to an embodiment of the present disclosure, will be described in detail with reference to the accompanying drawings.

[0045] A flush door 1 for a vehicle with an integrated track frame according to an embodiment of the present disclosure includes: a door frame 13 for the vehicle; a door glass 21 whose vertical movement is guided by the door frame 13; a decorative panel 28, fastened to the door frame 13 and guiding the vertical movement of the door glass 21 together with the door frame 13; and a slider 22, fixed to the end portion of the door glass 21 and moving vertically between the door frame 13 and the decorative panel 28.

[0046] Figure 3 An exploded perspective view of a flush door (hereinafter referred to as "door") for a vehicle according to an embodiment of the present disclosure is shown.

[0047] The door frame 13 forms the basic shape of the door 1. The components to be described below are mounted on the door frame 13 to form the door 1.

[0048] The inner panel 11 and the outer panel 12 are fastened to the door frame 13 on the inside and outside of the vehicle, respectively.

[0049] The door glass 21 is installed to move up and down on the door 1 for light and ventilation. The door glass 21 is installed to move up and down on the door frame 13.

[0050] A glass guide channel 24 is installed to support and seal the periphery of the door glass 21. The glass guide channel 24 includes an inner lip 24a and an outer lip 24b. The inner lip 24a is fixed to the end portion of the door frame 13 and seals the gap between the door frame 13 and the door glass 21. The outer lip 24b is fixed to the end portion of the decorative panel 28 and seals the gap between the end portion of the decorative panel 28 and the end portion of the door glass 21.

[0051] Decorative assembly 27 adorns the perimeter of door glass 21 within door 1. Decorative assembly 27 includes a decorative panel 28 and a decorative cover 29. The decorative cover 29 is fastened to the decorative panel 28. Specifically, the decorative cover 29 forms a continuous surface with the door glass 21 without any steps, thus forming a flush door 1. Decorative assembly 27 is mounted on door frame 13 by allowing insert bolts 28b formed on the decorative panel 28 to pass through door frame 13 and then fastening a fastening nut 28c to the insert bolts 28b.

[0052] The inner panel 11 is provided with a door module 23, in which a speaker, an adjuster for moving the door glass 21 up and down, etc. are installed.

[0053] Furthermore, an inner cover 25 is installed on the inside of the inner panel 11 to decorate the inside of the door 1. In the door 1, a trim piece is installed on the door module 23 to decorate the door module 23. A weatherstripping 26 for sealing the gap between the door 1 and another door, which is located along the longitudinal direction of the vehicle, is installed on the inner cover 25. For example, when the door 1 is a front door 1, the weatherstripping 26 for sealing the gap between the front door 1 and the rear door is installed on the inner cover 25.

[0054] Figure 4 and Figure 5 This is a cross-sectional view of door 1, for example, showing the B-pillar portion of the front door of a vehicle.

[0055] The door glass 21 moves up and down by the operation of an adjuster mounted on the door module 23, and the up and down movement of the end portion of the door glass 21 in the longitudinal direction of the vehicle is guided by the door frame 13.

[0056] Meanwhile, in order to form a continuous surface without any steps between the door glass 21 and the decorative cover 29, the up and down movement of the door glass 21 is guided by installing the slider 22 on the end portion of the door glass 21 along the longitudinal direction of the vehicle and guiding the slider 22.

[0057] When the door glass 21 moves up and down, the structure for guiding the up and down movement of the door glass 21 should be applied to the door 1. In related technologies, a track is used to guide the up and down movement of the sliding member 22, but in the embodiments of this disclosure, the structure for guiding the up and down movement of the sliding member 22 is directly formed on the door frame 13 to simplify the structure.

[0058] For this purpose, an inner guide portion 13a is formed on the door frame 13 to accommodate the slider 22. The inner guide portion 13a is recessed toward the inside of the vehicle to form a space in which the slider 22 is accommodated. Because the inner guide portion 13a serves as a track in the related technology, a track structure is applied to the door frame 13.

[0059] Here, since the inner guide portion 13a may not be able to completely surround the slider 22, the decorative panel 28 surrounds one side of the slider 22. That is, an outer guide portion 28a for covering the slider 22 on the outside of the vehicle is formed on the decorative panel 28, and the outer guide portion 28a is formed to surround the periphery of the slider 22 together with the inner guide portion 13a.

[0060] Since the three surfaces of the slider 22 are surrounded by the inner guide portion 13a and the outer guide portion 28a, the movement of the slider 22 in the longitudinal direction of the vehicle is restricted, and the up and down movement of the slider 22 can be achieved by the inner guide portion 13a and the outer guide portion 28a.

[0061] The slider 22 includes a main body portion 22a and a connecting portion 22b. The main body portion 22a is surrounded by an inner guide portion 13a and an outer guide portion 28a, and moves vertically along the height direction of the vehicle. The connecting portion 22b is used to connect the door glass 21 to the slider 22. The inner guide portion 13a and the outer guide portion 28a surround the main body portion 22a in a U-shaped configuration rotated 90 degrees. That is, since the three surfaces of the main body portion 22a, excluding the surface connected to the connecting portion 22b, are surrounded, the main body portion 22a is located inside the U-shaped space.

[0062] Between the inner guide section 13a and the outer guide section 28a, the main body section 22a is in a state where it can only move up and down, and its movement in the longitudinal direction of the vehicle is restricted.

[0063] The connecting portion 22b is fixed to one side of the door glass 21 using sealant 21a. In order to form a continuous surface without any steps between the door glass 21 and the decorative cover 29, a slider 22 is used, and the slider 22 is fixed to the door glass 21 via the connecting portion 22b.

[0064] A locking portion 13b is formed on the door frame 13 to restrict the movement of the slider 22 in the longitudinal direction of the vehicle. The locking portion 13b is formed to protrude outward toward the outside of the vehicle, thereby preventing the slider 22 from separating from the inner guide portion 13a.

[0065] Meanwhile, to prevent noise from being generated when the slider 22 moves up and down, an entry portion 22c is formed at each of the upper and lower ends of the slider 22 (see...). Figure 7The entry portion 22c is formed in an elliptical ring shape at the upper and lower ends of the main body portion 22a to prevent noise generated by the entry portion 22c. The entry portion is deformed to allow the main body portion 22a to contact the inner guide portion 13a or the outer guide portion 28a.

[0066] Furthermore, tensioning portions 22d and 22e are formed on the main body 22a to elastically support the slider 22 between the slider 22 and the door frame 13 when the slider moves up and down. The tensioning portions 22d and 22e are formed to protrude from the main body 22a and are elastically supported by the inner guide portion 13a, thereby absorbing the distribution between the main body 22a and the inner guide portion 13a. That is, the gap between the main body 22a and the inner guide portion 13a inevitably arises from assembly allowances or assembly errors during manufacturing and assembly. However, even if assembly allowances or assembly errors occur, the main body 22a is elastically supported inside the inner guide portion 13a due to the tensioning portions 22d and 22e, thereby preventing the effects caused by distribution (such as looseness or tightness).

[0067] Tensioning portions 22d and 22e include a first tensioning portion 22d and a second tensioning portion 22e. The first tensioning portion 22d is formed to protrude from the main body portion 22a in the width direction of the vehicle and elastically support the main body portion in the width direction (see...). Figure 7 The second tensioning portion 22e is formed to protrude from the main body portion 22a in the longitudinal direction of the vehicle and elastically support the main body portion 22a in the longitudinal direction (see...). Figure 6 ).

[0068] The first tensioning portion 22d can absorb the distribution in the width direction of the vehicle, and the second tensioning portion 22e can absorb the distribution in the longitudinal direction of the vehicle. (Reference) Figure 5 The first tensioning portion 22d elastically supports the main body portion 22a relative to the inner guide portion 13a between the main body portion 22a and the inner guide portion 13a, and thus absorbs the distribution between the main body portion 22a and the inner guide portion 13a. Similarly, the second tensioning portion 22e absorbs the distribution in the width direction of the vehicle.

[0069] Grease can be applied between the slider 22 and the door frame 13 (i.e., between the main body portion 22a and the inner guide portion 13a) to reduce friction.

[0070] In the embodiments of this disclosure, since the vertical movement of the slider 22 is guided by the door frame 13 and the decorative panel 28 rather than by the track, a space is formed between the door frame 13 and the inner panel 11. Here, a vertical beam 14 is used to strengthen the rigidity of the door 1.

[0071] The interior of the vertical beam 14 is hollow and is installed between the door frame 13 and the inner panel 11 along the height direction of the vehicle.

[0072] The vertical beam 14 is integrally formed with the door frame 13 and the inner panel 11. During the manufacture of the body-in-white (BIW) of the door 1, the vertical beam 14 is integrally formed with the door frame 13 and the inner panel 11 by welding. Subsequently, the outer panel 12 is joined to the outside of the door frame 13 by crimping and welding to form a door panel assembly. After assembling the glass guide channel 24 (e.g., the inner lip 24a of the glass guide channel) using tape 24c, the door glass 21 is installed. Because the trim assembly 27 is not installed until the door glass 21 is installed, the inner guide portion 13a is in a state of being open outwards in the width direction of the vehicle. Therefore, the door glass 21 can be easily installed by allowing the main body portion 22a of the slider 22 to be positioned inside the inner guide portion 13a in the width direction of the vehicle.

[0073] The door 1 is then completed by assembling the decorative component 27 and the outer lip 24b of the glass guide channel.

[0074] Figure 9 A flush door with an integrated track frame for a vehicle, according to another embodiment of the present disclosure, is shown.

[0075] This embodiment has a structure that is basically the same as the embodiment described above.

[0076] However, in this embodiment, the door frame 13 and the inner panel 11 are integrally formed. Therefore, the inner cover 25 is fixed to the inner surface of the door frame 13 (i.e., the surface of the door frame 13 facing the inside of the vehicle), thereby finishing the door frame 13.

[0077] Meanwhile, a weatherstripping 26, used to seal the gap between a door and another door located along the longitudinal direction of the vehicle, is fixed to the inner cover 25.

[0078] Figure 10 An assembly method for a flush door with an integrated track frame for a vehicle, according to an embodiment of the present disclosure, is shown.

[0079] An assembly method for a flush door with an integrated track frame for a vehicle according to an embodiment of the present disclosure includes: a temporary door panel assembly operation (S110), in which a main door panel assembly is assembled by arranging a vertical beam 14 between a door frame 13 and an inner panel 11 and fastening the door frame 13, the vertical beam 14, and the inner panel 11; a door panel assembly completion operation (S120), in which an outer door panel 12 is assembled on the outside of the main door panel assembly to complete the door panel assembly; a door glass installation operation (S140), in which a door glass 21 is installed such that a sliding member 22 mounted on the door glass 21 is disposed on an inner guide portion 13a formed on the door frame 13; and a decorative component assembly operation (S150), in which a decorative component 27 is assembled to the door frame 13 such that the outside of the sliding member 22 is covered.

[0080] The temporary door panel assembly operation (S110) includes assembling the main door panel assembly by assembling some components of the door panel assembly. In the temporary door panel assembly operation (S110), a vertical beam 14 is placed between the door frame 13 and the inner panel 11, and the door frame 13, vertical beam 14, and inner panel 11 are welded together to form a single unit. The vertical beam 14, located between the door frame 13 and the inner panel 11, improves the door 1's stability.

[0081] The door panel assembly completion operation (S120) includes assembling the outer door panel 12 onto the outside of the main door panel assembly. The outer door panel 12 is disposed on the main door panel assembly and the door panel assembly is completed by edge rolling and welding. The door panel assembly becomes the door BIW.

[0082] The glass guide channel installation operation (S130) includes installing the glass guide channel 24 (e.g., the inner lip 24a of the glass guide channel) onto the door panel assembly. The door frame 13 is attached to the inner lip 24a of the glass guide channel such that the inner lip 24a of the glass guide channel seals the gap between the door glass 21 and the door frame 13.

[0083] In the door glass installation operation (S140), the sliding member 22 mounted on the door glass 21 is provided on the inner guide portion 13a formed on the door frame 13. Because the inner guide portion 13a is open in the width direction of the vehicle, the door glass 21 moves from the outside to the inside in the width direction of the vehicle, so that the sliding member 22 mounted on the door glass 21 is positioned on the inner guide portion 13a. Therefore, the door glass 21 can be easily installed.

[0084] After the door glass installation operation (S140), the decorative component assembly operation (S150) for installing the decorative component 27 is performed. The decorative component assembly operation (S150) includes assembling the decorative component 27 to the door frame 13, such that the decorative component 27 adorns the periphery of the door glass 21, and the outer side of the sliding member 22 is covered by the outer guide portion 28a formed on the decorative panel 28.

[0085] In the trim assembly operation (S150), the trim component 27 is installed by moving it in the width direction of the vehicle, similar to the door glass 21.

[0086] In the trim assembly operation (S150), the trim panel 28 is fastened to the door frame 13 using insert bolts 28b formed on the trim panel 28. That is, as Figure 8 As shown, the decorative assembly 27 is fastened to the door frame 13 by allowing the insert bolt 28b of the decorative panel 28 to pass through the through hole 13c of the door frame 13 and then tightening the insert bolt with the fastening nut 28c.
