The rear part of the vehicle with a tailgate opening

Abstract

The present invention relates to a rear part of a vehicle body having a tailgate opening portion, which may have a tailgate opening portion for improving the torsional stiffness and durability of the vehicle body.

Description

Technical Field

[0001] The present invention relates to a rear part of a vehicle body having a tailgate opening, and more specifically, to a rear part of a vehicle body having a structure that improves the torsional rigidity and durability of the vehicle body. Background Technology

[0002] The vehicle body with a tailgate has a side panel section, which has a structure that can install and accommodate the taillights.

[0003] like Figure 14 and Figure 15 As shown, the side panel of a conventional vehicle with a tailgate is located above the rear wheel and on the side of the tailgate opening 101, and includes a lamp cover 103 on which a taillight 102 is mounted.

[0004] like Figure 15 and Figure 16 As shown, in a conventional vehicle with a tailgate, a side panel reinforcement 104 is applied vertically toward the wheel cover 105 to ensure the rigidity of the vehicle body side panel portion, and the lamp cover 103 of the outer side panel 107 is welded and connected to the inner side panel 108 to further enhance the rigidity of the vehicle body side panel portion.

[0005] like Figure 17 As shown, when the taillight 102 is not installed on a vehicle with a tailgate, as a replacement for omitting the lamp cover plate 103 (formed in a concave shape to install the taillight 102 on the side panel portion of the vehicle body), considering the vehicle body design, an extension plate 109 that is not welded and connected to the inner panel 108 of the side panel is applied, forming an empty space between the inner panel 108 of the side panel and the extension plate 109.

[0006] However, as mentioned above, when the lamp cover plate 103 is omitted, it is impossible to weld a connection between the inner side panel 108 and the extension plate 109. Therefore, the problem is that the rigidity of the side panel portion of the vehicle body is reduced, and the durability and noise, vibration, harshness (NVH) performance of the vehicle body are reduced.

[0007] The information included in this background section is intended only to enhance the understanding of the general background of the invention and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art.

[0065] like Figure 1 , Figure 2 as well as Figure 3 As shown, the rear portion 1 of a vehicle with a tailgate includes a rear body panel 10 and multiple reinforcing members 21, 22, 23, 24, 25, 26, 27, and 28. The rear body panel 10 has a tailgate opening portion T, and the multiple reinforcing members 21, 22, 23, 24, 25, 26, 27, and 28 are connected to the rear body panel 10. The tailgate opening portion T is the part of the vehicle whose tailgate is opened or closed.

[0066] The rear panel 10 of the vehicle body may include an upper rear panel 11, a lower rear panel 12, a right side panel inner panel 13, and a left side panel inner panel 14.

[0067] The upper rear panel 11 is the portion located above the tailgate opening portion T and surrounding the upper part of the tailgate opening portion T, while the lower rear panel 12 is the portion located below the tailgate opening portion T and surrounding the lower part of the tailgate opening portion. The lower rear panel 12 is located below the upper rear panel 11 and is spaced apart from the upper rear panel 11 by a predetermined interval.

[0068] In this configuration, the upper rear panel 11 is connected to the upper end of the right side panel inner panel 13 and the upper end of the left side panel inner panel 14. The upper rear panel 11 connects the upper end of the right side panel inner panel 13 to the upper end of the left side panel inner panel 14.

[0069] Furthermore, the lower rear plate 12 is connected to the lower end of the right side panel inner plate 13 and the lower end of the left side panel inner plate 14. The lower rear plate 12 connects the lower end of the right side panel inner plate 13 to the lower end of the left side panel inner plate 14.

[0070] The inner panel 13 of the right side panel is located to the right of the upper rear panel 11 and the lower rear panel 12, and the inner panel 14 of the left side panel is located to the left of the upper rear panel 11 and the lower rear panel 12. That is, the inner panel 13 of the right side panel and the inner panel 14 of the left side panel are located to the right and left of the tailgate opening T, respectively. The inner panels 13 of the right side panel and 14 of the left side panel, together with the upper rear panel 11 and the lower rear panel 12, are arranged on the outer periphery of the tailgate opening T and above the rear wheels of the vehicle.

[0071] The inner panel 13 of the right side enclosure and the inner panel 14 of the left side enclosure can be formed with similar or identical structures. When the inner panel 13 of the right side enclosure and the inner panel 14 of the left side enclosure are formed with similar structures, they can provide the same level of function and effect even if there are structural differences. Alternatively, when the inner panel 13 of the right side enclosure and the inner panel 14 of the left side enclosure are formed with identical structures, they can be symmetrical to each other.

[0072] The inner panel 13 of the right side panel and the inner panel 14 of the left side panel, together with the upper rear panel 11 and the lower rear panel 12, are arranged in a ring around the outer periphery of the tailgate opening T.

[0073] like Figure 1 and Figure 3 As shown, multiple reinforcing members 21, 22, 23, 24, 25, 26, 27, and 28 can be welded to the rear body panel 10. In this case, the multiple reinforcing members 21, 22, 23, 24, 25, 26, 27, and 28 are arranged in a ring shape on the outer periphery of the tailgate opening portion T.

[0074] The multiple reinforcing members 21, 22, 23, 24, 25, 26, 27 and 28 include: a first reinforcing member 21, a second reinforcing member 22, a right side panel reinforcing member 23 and an upper right reinforcing member 24, and a left side panel reinforcing member 28 and an upper left reinforcing member 25. The first reinforcing member 21 is connected to the upper rear panel 11; the second reinforcing member 22 is connected to the lower rear panel 12; the right side panel reinforcing member 23 and the upper right reinforcing member 24 are connected to the right side panel inner panel 13; and the left side panel reinforcing member 28 and the upper left reinforcing member 25 are connected to the left side panel inner panel 14.

[0075] Furthermore, based on the shapes of the inner panel 13 of the right side panel and the inner panel 14 of the left side panel, the third right reinforcing member 26 can be further connected to the inner panel 13 of the right side panel, and the third left reinforcing member 27 can be further connected to the inner panel 14 of the left side panel. The third right reinforcing member 26 and the third left reinforcing member 27 can be connected to the right end and the left end of the second reinforcing member 22, respectively.

[0076] like Figure 1 , Figure 2 as well as Figure 3 As shown, a plurality of reinforcing members 21, 22, 23, 24, 25, 26, 27 and 28 are connected to each other such that the ends of two adjacent reinforcing members among the plurality of reinforcing members 21, 22, 23, 24, 25, 26, 27 and 28 are stacked and connected to each other, and the end of either of the two adjacent reinforcing members connected in this way is provided with a partition wall extending toward and connecting to the rear panel 10 of the vehicle body.

[0077] like Figure 4A As shown, the right end of the first reinforcing member 21 is stacked and connected to the upper end of the upper right reinforcing member 24. The upper end of the upper right reinforcing member 24 is provided with a partition wall, namely the upper right partition wall 24d, which is formed to bend toward the inner panel 13 of the right side panel. The upper right partition wall 24d is formed to bend at the upper end of the upper right reinforcing member 24, extend toward the outer surface of the inner panel 13 of the right side panel, and is engaged and fixed to the inner panel 13 of the right side panel by the upper top flange 24c.

[0078] The upper left reinforcement 25 can be integrated into the inner panel 14 of the left side panel in a structure that is symmetrical to the upper right reinforcement 24 and connected to the left end of the first reinforcement 21.

[0079] like Figure 4B As shown, the left end of the first reinforcing member 21 is stacked and connected to the upper end of the upper left reinforcing member 25. The upper end of the upper left reinforcing member 25 may be provided with a partition wall formed to bend toward the inner panel 14 of the left side panel, namely the upper left partition wall 25a. The upper left partition wall 25a may be formed to bend at the upper end of the upper left reinforcing member 25, may extend toward the outer surface of the inner panel 14 of the left side panel, and may be joined and fixed to the inner panel 14 of the left side panel by a flange 25b.

[0080] like Figure 5A As shown, the lower end of the right side panel reinforcement 23 is stacked and connected to the upper end of the third right reinforcement 26. The upper end of the third right reinforcement 26 is provided with a partition wall formed to bend toward the inner panel 13 of the right side panel, namely the third right partition wall 26a. The third right partition wall 26a extends toward the outer surface of the inner panel 13 of the right side panel and is joined and fixed to the inner panel 13 of the right side panel by a flange 26b.

[0081] The left side panel reinforcement 28 can be integrated into the left side panel inner panel 14 in a structure that is symmetrical with the right side panel reinforcement 23 and connected to the third left reinforcement 27.

[0082] like Figure 5B As shown, the lower end of the left side panel reinforcement 28 is stacked and connected to the upper end of the third left reinforcement 27. The upper end of the third left reinforcement 27 may be provided with a partition wall formed to bend toward the inner panel 14 of the left side panel, namely the third left partition wall 27a. The third left partition wall 27a extends toward the outer surface of the inner panel 14 of the left side panel and is joined and fixed to the inner panel 14 of the left side panel by a flange 27b.

[0083] like Figure 6A As shown, the lower end of the third right reinforcing member 26 is stacked and connected to the right end of the second reinforcing member 22. The right end of the second reinforcing member 22 is provided with a partition wall formed to bend toward the lower rear plate 12, namely the lower right partition wall 22a. The lower right partition wall 22a extends toward the outer surface of the lower rear plate 12 and is joined and fixed to the outer surface of the lower rear plate 12 by a flange 22c.

[0084] The third left reinforcement 27 can be integrated into the inner panel 14 of the left side panel in a structure that is symmetrical to the third right reinforcement 26 and connected to the left end of the second reinforcement 22.

[0085] like Figure 6B As shown, the lower end of the third left reinforcing member 27 is stacked and connected to the left end of the second reinforcing member 22. The left end of the second reinforcing member 22 is provided with a partition wall formed to bend toward the lower rear plate 12, namely the lower left partition wall 22b. The lower left partition wall 22b can extend toward the outer surface of the lower rear plate 12 and can be engaged and fixed to the outer surface of the lower rear plate 12 by a flange 22d.

[0086] Here, the following will refer to Figures 7 to 12 The connection structure between the right side panel reinforcement 23 and the upper right reinforcement 24 is further described.

[0087] Based on the first reinforcing member 21 and the second reinforcing member 22, the left side panel reinforcing member 28 can be configured to be symmetrical with the right side panel reinforcing member 23, as will be described below.

[0088] like Figure 7 and Figure 8 As shown, to ensure rigidity, the right side panel reinforcement 23 and the upper right reinforcement 24 are attached to the inner right side panel 13. The right side panel reinforcement 23 and the upper right reinforcement 24 can be welded to the inner right side panel 13.

[0089] The right side panel reinforcement 23 is attached to the inner surface (facing the vehicle interior) and the outer surface (facing the vehicle exterior) of the inner panel 13 of the right side panel.

[0090] In this configuration, the right side panel reinforcement 23 is positioned in the rear portion of the inner panel 13 of the right side panel, adjacent to the tailgate opening. The right side panel reinforcement 23 is positioned immediately adjacent to the tailgate opening T.

[0091] like Figure 9 As shown, the right side panel reinforcement 23 may include a bottom wall 23a, a front wall 23b, a rear wall 23c, and a side panel partition wall 23d.

[0092] like Figure 10A As shown, the bottom wall 23a is positioned at a predetermined height from the outer surface of the inner panel 13 of the right side panel. That is, the bottom wall 23a is spaced apart from the outer surface of the inner panel 13 of the right side panel in the left-right direction of the vehicle. In this case, the outer surface of the upper end of the bottom wall 23a contacts the inner surface of the lower end of the upper right reinforcing member 24. The bottom wall 23a can be formed of a flat plate.

[0093] like Figure 11 and Figure 12 As shown, the front wall 23b is formed to bend at the front end of the bottom wall 23a to face the outer surface of the right side panel inner plate 13, the rear wall 23c is formed to bend at the rear end of the bottom wall 23a to face the outer surface of the right side panel inner plate 13, and the side panel partition wall 23d is formed to bend at the upper end of the bottom wall 23a to face the outer surface of the right side panel inner plate 13.

[0094] In this configuration, the side panel partition wall 23d is formed to connect the upper portion of the front wall 23b to the upper portion of the rear wall 23c. That is, the side panel partition wall 23d is integrally formed with the upper portions of the front wall 23b and the rear wall 23c. The side panel partition wall 23d is formed to curve rearward from the upper portion of the front wall 23b to the lower portion of the front wall 23b, and to curve forward on the upper portion of the rear wall 23c.

[0095] The side panel partition wall 23d is formed to extend from the lower end of the upper right reinforcement 24 to the inner right side panel 13, with the upper right reinforcement 24 stacked on the outer surface of the upper portion of the right side panel reinforcement 23. The side panel partition wall 23d extends from the inner surface of the lower end of the upper right reinforcement 24 to the outer surface of the inner right side panel 13. In this case, the side panel partition wall 23d is formed to extend on the upper portion of the bottom wall 23a in the left-right direction of the vehicle.

[0096] The side panel partition wall 23d is a partition wall for the right side panel reinforcement 23, and is configured to divide the space enclosed by the right side panel inner panel 13, the right side panel reinforcement 23 and the upper right reinforcement 24 into an upper space and a lower space, thereby increasing the rigidity of the rear part 1 of the vehicle body, including the right side panel part QR.

[0097] The right side panel portion QR includes a right side panel inner panel 13 and a right side panel reinforcement 23 and a right upper reinforcement 24 connected to the right side panel inner panel 13. The right side panel portion QR may further include a right front reinforcement 31.

[0098] In this case, in order to more effectively increase the rigidity of the right side panel portion QR, the side panel partition wall 23d can be arranged to be inclined relative to the right side panel inner panel 13. The side panel partition wall 23d can be arranged to be inclined at a predetermined angle relative to the right side panel inner panel 13 based on the portion to which the side panel partition wall 23d is attached.

[0099] Furthermore, the right side panel reinforcement 23 may include a front flange 23e, a rear flange 23f, and an upper flange 23g of the side panel that are welded to the inner panel 13 of the right side panel.

[0100] The front flange 23e of the side panel extends from the end of the front wall 23b, the rear flange 23f of the side panel extends from the end of the rear wall 23c, and the upper flange 23g of the side panel extends from the end of the side panel partition wall 23d.

[0101] In this configuration, in order to attach the front flange 23e, the rear flange 23f, and the upper flange 23g of the side panel to the inner panel 13 of the right side panel, the front flange 23e is formed to be bent at the end portion of the front wall 23b, the rear flange 23f is formed to be bent at the end portion of the rear wall 23c, and the upper flange 23g is formed to be bent at the end portion of the side panel partition wall 23d.

In this case, to fix the position of the right-side panel reinforcement 23, the upper flange 23g of the side panel is locatingly welded to the inner right-side panel 13.

[0103] With the side panel flange 23g positioned and welded to the right side panel inner plate 13, the upper right reinforcement 24 is arranged on the outer surface of the right side panel reinforcement 23, so that the lower end of the upper right reinforcement 24 is stacked on the outer surface of the upper end of the right side panel inner plate 13. Then, the flanges 23e, 23f, and 23g of the right side panel reinforcement 23 and the flanges 24a, 24b, and 24c of the upper right reinforcement 24 are welded to the right side panel inner plate 13. In this case, the front flange 23e and the rear flange 23f of the side panel are first welded to the right side panel inner plate 13 together with the flanges 24a, 24b, and 24c of the upper right reinforcement 24, and then the upper flange 23g of the side panel is welded to the right side panel inner plate 13.

[0104] In order to weld the flange 23g on the side panel, a through hole 24e is formed in the lower part of the upper right reinforcement 24, so that the flange 23g on the side panel passes through the upper right reinforcement 24 and is joined to the inner panel 13 of the right side panel.

[0105] With the upper ends of the right side panel reinforcement 23 stacked and overlapping, the lower end of the upper right reinforcement 24 is attached to the inner panel 13 of the right side panel. That is, the upper ends of the right side panel reinforcement 23 and the lower ends of the upper right reinforcement 24 can be connected to each other in a stacked manner. In this case, the lower end of the upper right reinforcement 24 can be formed to have a shape that matches the upper end of the right side panel reinforcement 23. The cross-sectional structure of the shape.

[0106] The upper right reinforcement 24 is arranged above the right side panel reinforcement 23 and is attached to the outer surface of the inner panel 13 of the right side panel. The lower end of the upper right reinforcement 24 can be stacked on the outer side of the upper end of the right side panel reinforcement 23.

[0107] In this configuration, the lower end of the upper right reinforcement 24 can be attached to the inner panel 13 of the right side panel and to the front flange 23e of the side panel of the right side panel reinforcement 23. Furthermore, the lower end of the upper front flange 24a can be welded to the front flange 23e of the side panel, and the lower end of the upper rear flange 24b can be welded to the inner panel 13 of the right side panel.

[0108] The upper right reinforcement 24 includes an upper front flange 24a, an upper rear flange 24b, and an upper top flange 24c. The upper front flange 24a is formed to bend and extend from the front end portion of the upper right reinforcement 24, the upper rear flange 24b is formed to bend and extend from the rear end portion of the upper right reinforcement 24, and the upper top flange 24c is formed to bend and extend from the upper end portion of the upper right reinforcement 24.

[0109] refer to Figure 7 , Figure 11 as well as Figure 12The upper front flange 24a is attached to the outer surface of the inner panel 13 of the right side panel. In this case, the lower end of the upper front flange 24a can partially overlap and be attached to the front flange 23e of the side panel. The upper rear flange 24b and the upper top flange 24c are attached to the outer surface of the inner panel 13 of the right side panel.

[0110] In this configuration, the upper right reinforcement 24 can be positioned above the right side panel reinforcement 23, adjacent to the tailgate opening portion T. The upper right reinforcement 24 can be arranged together with the right side panel reinforcement 23 in the outer peripheral direction of the tailgate opening portion T, and the upper right reinforcement 24 can be positioned at the upper corner of the tailgate opening portion T.

[0111] Furthermore, based on the first reinforcing member 21 and the second reinforcing member 22, the left side panel portion QL of the rear part of the vehicle body 1 can be configured to be symmetrical with respect to the right side panel portion QR. The left side panel portion QL includes a left side panel inner panel 14 and a left side panel reinforcing member 28 and a left upper reinforcing member 25 connected to the left side panel inner panel 14. The left side panel portion QL may further include a left front reinforcing member.

[0112] The left side panel reinforcement 28 can be formed in a structure that is symmetrical about left and right with respect to the right side panel reinforcement 23, and is connected to the left side panel inner panel 14 in a structure that is symmetrical about left and right with respect to the right side panel reinforcement 23, and is connected to the upper left reinforcement 25 and the third left reinforcement 27 in a structure that is symmetrical about left and right with respect to the right side panel reinforcement 23.

[0113] The upper end of the left side panel reinforcement 28 and the lower end of the upper left reinforcement 25 can be connected to each other in a stacked manner. The left side panel reinforcement 28 can be arranged below the upper left reinforcement 25, and the lower end of the upper left reinforcement 25 can be connected to the inner panel 14 of the left side panel in a manner that is arranged on the outside of the upper end of the left side panel reinforcement 28.

[0114] The upper end of the left side panel reinforcement 28 may be provided with a partition wall that is bent toward the inner panel 14 of the left side panel, namely the left side panel partition wall 28a. The left side panel partition wall 28a may be formed to be symmetrical to the side panel partition wall 23d of the right side panel reinforcement 23.

[0115] Furthermore, the left front reinforcement can be formed to be symmetrical about the left and right sides with respect to the right front reinforcement 31, and can be connected to the inner panel 14 of the left side panel to be symmetrical about the left and right sides with respect to the right front reinforcement 31.

[0116] As described above, the rigidity of the rear part 1 of the vehicle body can be increased due to the annular connection structure and the structure of the partition wall of the reinforcing members 21, 22, 23, 24, 25, 26, 27 and 28 connected to the rear panel 10 of the vehicle body.

[0117] Furthermore, in the rear part 1 of the vehicle body with a tailgate, significant torsional deformation occurs in the upper and lower portions and corner portions adjacent to the tailgate opening. The reinforcing partitions are arranged in such portions (i.e., the upper and lower portions and corner portions adjacent to the tailgate opening), thereby effectively strengthening the rigidity of the parts of the rear part 1 that are prone to torsional deformation.

[0118] Meanwhile, the aforementioned through hole 24e can be arranged on the lower side of the upper right reinforcement 24. The through hole 24e is used when the flange 23g on the side panel is welded to the inner panel 13 of the right side panel, and the through hole 24e is formed in the upper right reinforcement 24 so that the nozzle of the welding gun passes through the through hole 24e.

[0119] The through hole 24e can be configured to be collinear with the flange 23g on the side panel based on the left and right directions of the vehicle. By passing the welding gun through the through hole 24e, the flange 23g on the side panel of the right side panel reinforcement 23 can be completely welded to the inner panel 13 of the right side panel.

[0120] Since the through hole 24e is formed in the upper right reinforcement 24, the flange 23g on the side panel can be welded to the inner right panel 13 when the upper right reinforcement 24 is arranged to stack on the inner right side panel 13 and the inner right side panel reinforcement 23.

[0121] Furthermore, such as Figure 8 and Figure 13 As shown, it is formed with approximately The right front stiffener 31, with its shaped cross-sectional structure, can be further connected to the inner panel 13 of the right side panel to increase rigidity.

[0122] The right front reinforcement 31 can be welded to the outer surface of the right side panel inner plate 13. In this case, the upper end of the right front reinforcement 31, which is stacked on the central portion of the right side panel reinforcement 23, can be joined to the central portion of the right side panel reinforcement 23. The portion of the right front reinforcement 31 other than the upper end, that is, the lower portion of the right front reinforcement 31, extends downward to the front side of the right side panel reinforcement 23 to be joined to the outer surface of the right side panel inner plate 13.

[0123] The upper end of the right front reinforcement 31 is arranged below the upper right reinforcement 24, and the lower end of the right front reinforcement 31 is spaced apart from the lower part of the right side panel reinforcement 23 in the longitudinal direction of the vehicle by a predetermined distance.

[0124] Therefore, the right front reinforcement 31 and the right side panel reinforcement 23 are approximately Shape arrangement. In this case, the lower end of the right front reinforcement 31 can be separated from the lower end of the right side panel reinforcement 23 by a predetermined distance.

[0125] The right front reinforcement 31 is arranged obliquely from the center portion of the right side panel reinforcement 23 toward the front side of the wheel cover 13a, and the right side panel reinforcement 23 is arranged obliquely on the upper part of the right side panel inner plate 13 toward the rear side of the wheel cover 13a.

[0126] The lower part of the right front reinforcement 31 can be arranged to extend to the front side of the wheel cover 13a provided on the lower part of the inner panel 13 of the right side panel. In this case, the lower part of the right side panel reinforcement 23 can be formed to extend to the rear upper side of the wheel cover 13a.

[0127] Furthermore, in this case, the front position of the wheel cover plate 13a arranged on the lower end portion of the right front reinforcement 31 can be the position where the striker of the vehicle's rear door is installed.

[0128] As described above, since the right front reinforcement 31 is connected to the right side panel inner panel 13, the stiffness and side impact performance of the rear part 1 of the vehicle body, which may be relatively insufficient due to the right side panel reinforcement 23 being arranged on the rear portion of the right side panel inner panel 13, can be further improved. When the right side panel reinforcement 23 is arranged in the rear portion of the right side panel inner panel 13, the stiffness of the rear part 1 of the vehicle body may be reduced compared to the case where the right side panel reinforcement 23 is arranged in the center portion of the right side panel inner panel 13.

[0129] Furthermore, the right front reinforcement 31 can be joined to the right side panel reinforcement 23 and the right side panel inner panel 13 by means of flanges formed at each of the front end, rear end and upper end portions of the right front reinforcement 31.

[0130] According to various aspects of the present invention, the rigidity of the rear part of the vehicle body can be increased due to the annular connection structure and the structure of the partition wall of the reinforcing member connected to the rear panel of the vehicle body, and the partition wall of the reinforcing member is arranged in the upper and lower parts and corner parts of the rear part of the vehicle body adjacent to the tailgate opening, thereby more effectively strengthening the rigidity of the parts of the rear part of the vehicle body that are prone to torsional deformation.
