Description

Technical Field

[0001] The present invention relates to a body member assembly, and more particularly, to a body member assembly that can also be used as a seat rail. Background Art

[0002] Figure 1 is a view showing a conventional body member assembly, Figure 2 is a cross-sectional view taken along the Figure 1 X-X line in

[0003] The conventional body member assembly is configured to be joined to a vehicle floor panel and a seat rail or the like can be mounted thereon while ensuring the rigidity of the body.

[0004] As shown in the figure, the body member assembly is formed into the following structure: wherein, a pair of seat cross members 21 are joined transversely across the floor panel 10. The seat cross members 21 and a plurality of body longitudinal members 22 are joined. One end of each body longitudinal member 22 is joined to the seat cross member 21.

[0005] Since the body member assembly is constructed by combining steel-based single pieces manufactured by pressing or stamping methods, the number of parts, including body parts and seat parts to be described below, is excessive.

[0006] Therefore, there are limitations in that it is difficult to simplify the assembly process, difficult to construct the layout of interior parts, and difficult to construct a simple interior styling due to the excessive number of parts. In addition, due to the high quality control cost of managing the gaps / steps between connecting parts, and due to the instability of the gaps between parts caused by manufacturing dispersion, the possibility of occurrence of joint and abnormal noise (BSR) problems is very high.

[0007] In addition, the structure of a conventional vehicle is such that seat rails are provided on the body longitudinal members 22 to overlap each other. This results in redundancy and weight increase.

[0008] In particular, since the body longitudinal member 22 has an interrupted structure as shown in the figure, there are limitations in terms of the combination with the seat rail and the structural rigidity.

[0009] Therefore, when it is necessary to improve the side collision rigidity, it is only possible to improve the side collision rigidity by increasing the thickness of each seat cross member 21 as a whole or by adding reinforcing materials or structures inside the seat cross member 21.

[0010] The subject matter described above in the background art section is intended to assist in understanding the background of the present invention. The background art section may include subject matters that are not related to the related art known to those of ordinary skill in the art to which the present technology belongs. Summary of the Invention

[0011] The present invention is dedicated to solving the above problems. The present invention aims to provide an integrated seat rail and body member assembly, which can integrate overlapping functions, ensure body rigidity, and reduce the number of parts or manufacturing or assembly processes. The present invention achieves the above object by forming an integrated body member and simultaneously integrating the seat rail with the body member.

[0012] According to one aspect of the present invention, a body member assembly having an integrated seat rail is combined with the vehicle floor panel. The integrated body member assembly includes a plurality of body longitudinal members, which are combined with the floor panel and arranged along the transverse direction of the body. The integrated body member assembly further includes a plurality of seat transverse members, which are combined with the floor panel and the two end portions of which are respectively combined with the side end portions of the respective adjacent body longitudinal members.

[0013] In addition, the plurality of seat transverse members can be arranged in multiple rows.

[0014] In addition, a seat upper rail combined with the lower part of the seat is slidably mounted on one or more corresponding body longitudinal members.

[0015] In addition, the body longitudinal members can be formed to extend to positions corresponding to the first row seat and the second row seat of the vehicle.

[0016] In addition, the seat rail integrated body member assembly may further include side reinforcing members, which are combined with the side surfaces of the outermost body longitudinal members among the plurality of body longitudinal members.

[0017] Here, the body longitudinal members and the side reinforcing members can be joined by metal inert gas (MIG) welding.

[0018] In addition, the body longitudinal members and the seat transverse members can be joined by MIG welding.

[0019] Meanwhile, the body longitudinal members and the floor panel, and the seat transverse members and the floor panel can be joined by MIG welding, spot welding, self-piercing riveting (SPR) or any combination thereof.

[0020] In addition, ribs can be formed inside the body longitudinal members and inside the seat transverse members.

[0021] In addition, the seat rail integrated body member may further include a console member, the two end portions of which are respectively combined with the seat transverse member in the first row and the seat transverse member in the second row, and a console is mounted on the console member.

[0022] According to the present invention, by including body components and seat components, the number of parts can be significantly reduced and the weight can be reduced.

[0023] Nevertheless, by changing the interrupted structure of the longitudinal member to an improved continuous structure, the structure of the present invention has an advantage over the conventional structure in ensuring static or dynamic rigidity.

[0024] Therefore, by eliminating the connection structure between components, the number of manufacturing or assembly processes for improving collision performance adjustment can be reduced (without increasing the processes of forming or joining), and improvement in terms of interface / abnormal noise (BSR) can be achieved.

[0025] In addition, the use of a separate rail for installing the seat can be eliminated.

[0026] In addition, the front-back sliding range of the seat can be expanded, and it is easy to achieve an interior of a lounge concept when applying the battery cell to a vehicle (CTV) (body-battery integrated structure). BRIEF DESCRIPTION OF THE DRAWINGS

[0036] To fully understand the present invention, the operational advantages of the present invention, and the objectives achieved by implementing the present invention, reference may be made to the accompanying drawings showing embodiments of the present invention and the content described in the drawings.

[0037] When describing embodiments of the present invention, descriptions of known technologies or repetitive descriptions that may unnecessarily obscure the gist of the present invention will be reduced or omitted. When a component, device, element, etc. disclosed in the present invention is described as having a certain purpose or performing a certain operation, function, etc., the component, device, or element should herein be regarded as "configured to" meet that purpose or perform that operation or function.

[0038] Figure 3 is a view showing a seat rail integrated body member assembly according to the present invention, i.e., a body member assembly 100 having an integrated seat rail. Additionally, Figure 4 is along Figure 3 a cross-sectional view taken along line A-A in Figure 5 is along Figure 3 a cross-sectional view taken along line B-B in Figure 6 is along Figure 3 a cross-sectional view taken along line C-C in

[0039] Hereinafter, reference is made to Figures 3 - 6 describe a body member assembly 100 according to an embodiment of the present invention.

[0040] The body member assembly 100 according to the present invention is an integrated member assembly joined to the vehicle floor 10, and the seat rail is integrated with the body member assembly. Compared with conventional assemblies, the body member assembly 100 can have greater rigidity, can reduce the number of parts, and can be used as a seat rail.

[0041] The body member assembly 100 includes a body longitudinal member 110 and a seat transverse member 120.

[0042] The body longitudinal member 110 is joined to the floor 10 in the longitudinal direction of the vehicle body. As Figure 3 shown, a plurality of body longitudinal members 110 can be arranged identically and spaced apart in the lateral direction of the vehicle body.

[0043] The body longitudinal member 110 can be made of 6000 series or 7000 series aluminum, and can be formed by an aluminum extrusion method or the like. A plurality of seat transverse members 120 and side reinforcement members 130 located on each side of the vehicle body can also be provided in the same manner.

[0044] In addition, multiple seat lateral members 120 can be joined to the floor panel 10. Two end portions of the seat lateral member 120 are respectively joined to the side end portions of adjacent (i.e., neighboring) body longitudinal members 110 in the body longitudinal members 110. Opposite end portions of the seat lateral member 120 can be joined to the corresponding or adjacent body longitudinal members 110 by means such as metal inert gas (MIG) welding.

[0045] In addition, multiple seat lateral members 120 can be arranged in multiple rows as shown in the figure. Multiple seat lateral members 120 can be arranged to form a row by being disposed between multiple body longitudinal members 110, and multiple rows of seat lateral members 120 can also be provided, as Figure 3 shown.

[0046] Therefore, the body longitudinal members 110 form a continuous structure in the front-rear longitudinal direction of the vehicle body, which has an advantage in ensuring static or dynamic rigidity compared with the conventional longitudinal members having an interrupted structure.

[0047] In addition, each body longitudinal member 110 is formed as a continuous structure in the front-rear longitudinal direction of the vehicle body. Since the body longitudinal member 110 can be used as a seat rail, specifically a seat lower rail or a support member, the seat upper rail combined with the seat will be combined with the body longitudinal member 110. Thus, the seat can slide along the body longitudinal member 110 in the front-rear longitudinal direction of the vehicle body.

[0048] In addition, in the conventional design, since installation points for independently assembling the seat rails need to be provided, sliding loss space is inevitably generated. However, the vehicle body member assembly 100 according to the present invention can improve the conventional loss space through an integrated seat rail structure.

[0049] Therefore, the sliding range of the seat will increase, and the body longitudinal member 110 can be formed from the first row of seats to the second row of seats.

[0050] In addition, in order to cope with irregular rods, a side reinforcement member 130 formed by an aluminum extrusion method can be joined to the laterally exposed side surface portion of the outermost body longitudinal member 110 among the multiple body longitudinal members 110. The side reinforcement member 130 can be joined by means such as MIG welding.

[0051] In other words, as Figure 7 shown, the aluminum areas can be joined by MIG welding. In addition, when the floor panel 10 is made of aluminum, the vehicle body member assembly and the floor panel 10 can be joined by MIG welding, aluminum spot welding or SPR (Self-Piercing Rivet), and when the floor panel 10 is made of steel, the vehicle body member assembly and the floor panel 10 can be joined by SPR.

[0052] In addition, as Figures 4 - 6 shown, longitudinal ribs or transverse ribs can be formed inside the vehicle body longitudinal member 110, the seat transverse member 120, and the side reinforcement member 130 to enhance the structural rigidity. The section modulus (rigidity) can be adjusted by adjusting the thickness of the aluminum extrusion material and the thickness, arrangement, and number of the ribs.

[0053] Therefore, in order to improve the conventional lateral collision rigidity, there is no need to increase the overall thickness of the members or add a process of adding reinforcement members inside or within the members.

[0054] As described above, in the vehicle body member assembly structure according to the present invention, the vehicle body longitudinal member 110 can be formed as an integral long slide rail and configured to extend from the first row seat to the second row seat. Due to the problems of the structure for placing the long guide rail caused by the B-pillar and the problem of arranging the number of assembly processes during the online assembly process, it is difficult to apply the first row / second row integral long slide rail for realizing the lounge seat concept to the conventional internal combustion engine (ICE) and electric vehicle (EV) structures.

[0055] This limitation can be solved by the following method: moving the seat freely to the first row or the second row by the following method, as Figures 8 - 11 shown, applying the vehicle body member assembly 100 of the present invention to a vehicle having a CTV (Cell To Vehicle, vehicle body-battery integrated structure). Thus, the interior space of the vehicle can be realized as a space with a lounge concept.

[0056] In step 1, assemble the body in white (BIW, Body In White) 210 excluding the floor panel.

[0057] In step 2, pre-assemble the seat rail integrated vehicle body member assembly 100 according to the present invention (wherein the vehicle body longitudinal member 110 serves as the first row / second row long slide rail) to the battery box 220 (in which the battery is embedded).

[0058] In step 3, pre-assemble the seat S to the seat rail integrated vehicle body member assembly 100 in step 2.

[0059] In addition, in step 4, by assembling the battery system (in which the BIW 210 and the equipped components are pre-installed to overcome the above limitations), the interior space can be formed as a space with a lounge concept through the long slide rail.

[0060] Next, Figure 12 and Figure 13 are views showing other embodiments of the present invention.

[0061] In one embodiment, the seat rail integrated body member assembly may further include a console member 140. Two end portions of the console member 140 are respectively joined to the corresponding seat lateral members 120 of the first row and the corresponding seat lateral members 120 of the second row. A console 30 may be slidably mounted on the console member 140.

[0062] Although the present invention has been described above by referring to certain embodiments with reference to the accompanying drawings, the present invention is not limited to the described embodiments. It is obvious that those of ordinary skill in the art can make various modifications and changes without departing from the spirit and scope of the present invention. Therefore, these modified embodiments or changed embodiments should be included within the claims of the present invention, and the scope of the present invention should be interpreted according to the appended claims.
