Wherever possible, the same reference numbers will be used in the different drawings / taken to indicate the same or similar elements. While the application will be described in conjunction with exemplary embodiments, it will be understood that they are not intended to limit the application to these embodiments.

[0046] Figure 1 This is a partial side view of the vehicle body side structure of an embodiment of the present invention, viewed from the outside of the vehicle, showing the axes X, Y, and Z. Figure 2 yes Figure 1 A partial side view of the vehicle body side structure viewed from inside the vehicle. Figure 3 yes Figure 2 A cross-sectional view of the side structure of the vehicle body along line II. Please refer to... Figures 1 to 3 The vehicle body side structure 100 of this embodiment includes a hollow vehicle body frame 110. The vehicle body frame 110 includes a side beam 112, a center pillar outer member 114, a center pillar inner member 116, and a center pillar reinforcing rib 118. The side beam 112 includes a side beam outer member 1121 and a side beam inner member 1122 that are joined together and extend along the longitudinal direction (axial direction Y) of the vehicle body. The center pillar outer member 114 extends upward from the side beam 112, and the center pillar inner member 116 is disposed on the inner side of the center pillar outer member 114 in the vehicle width direction (axial direction X). The center pillar reinforcing rib 118 is disposed between the center pillar outer member 114 and the center pillar inner member 116.

[0047] Figure 4 Showing packing entering Figure 3 Within the vehicle's frame. Please refer to... Figure 3 and Figure 4 The side structure 100 of the vehicle body also includes a partition 120, which is disposed within the body frame 110 and located between the center pillar reinforcement 118, the side beam 112, and the center pillar inner member 116. The partition 120 is used to separate the interior of the body frame 110 to form at least a portion of the filling space S that can accommodate the filler M. The center pillar inner member 116 of the body frame 110 has a filling hole 116a through which the filler M enters the body frame 110.

[0048] Figure 5 yes Figure 3 A three-dimensional view of the separator. Figure 6 yes Figure 3 The separator is shown in a three-dimensional view from another perspective. Please refer to... Figures 3 to 6 Specifically, the separator 120 is, for example, a resin part and includes an integrally formed upper part 122, a lower part 124, and a connecting part 126. The upper part 122 is located above the filling space S, and the lower part 124 is located below the filling space S. The connecting part 126 connects the upper part 122 and the lower part 124 to prevent relative movement between the upper part 122 and the lower part 124.

[0049] Figure 7 yes Figure 5 Side view of the separator. Figure 8 yes Figure 7 The cross-sectional view of the separator along line II-II. Please refer to... Figure 7 and Figure 8The side beam outer member 1121 of the vehicle body frame 110 has a mounting hole 1121a, and the lower portion 124 of the partition member 120 has a protrusion 1241 which is inserted into the mounting hole 1121a to fix the position of the partition member 120.

[0050] As described above, in the vehicle body side structure 100 of the present embodiment, the partition member 120 forms a filling space S between the upper portion 122 and the lower portion 124 and the upper portion 122 and the lower portion 124 are connected to each other by the connecting portion 126. When the filler M is foamed in the filling space S, the upper portion 122 is pushed upward by the foamed filler M and the lower portion 124 is pushed downward by the foamed filler M, and the force of the foamed filler M pushing upward and the force of the foamed filler M pushing downward cancel each other out, effectively preventing the displacement of the partition member 120. Therefore, it is sufficient to provide the protrusion 1241 of the lower portion 124 of the partition member 120 to be inserted into the vehicle body frame 110 to prevent the position of the partition member 120 from shifting when the filler M is foamed, and it is not necessary to lock the partition member 120 by a complicated locking structure such as a claw shape. Thus, the vehicle body side structure 100 of the present embodiment can prevent the displacement of the partition member 120 by simply assembling the partition member.

[0051] Referring to Figure 8 In detail, the protrusion 1241 of the present embodiment includes a flange portion 1241a and an insertion portion 1241b. The diameter of the flange portion 1241a is larger than the diameter of the mounting hole 1121a, and the diameter of the insertion portion 1241b is equal to or smaller than the diameter of the mounting hole 1121a. The insertion portion 1241b is not claw-shaped but columnar, and thus the structure of the insertion portion 1241b is simple. The insertion portion 1241b extends from the flange portion 1241a toward the side beam outer member 1121 of the vehicle body frame 110 and is inserted into the mounting hole 1121a. By providing the flange portion 1241a having a larger diameter, the partition member 120 can be stably mounted, and it is also possible to prevent the partition member 120 from making an abnormal sound when the partition member 120 is mounted to the side beam outer member 1121 of the vehicle body frame 110.

[0052] Referring to Figures 5 to 7 In the present embodiment, the partition member 120 includes a first partition member 120A and a second partition member 120B which are separately formed. The upper portion 122 of the first partition member 120A and the upper portion 122 of the second partition member 120B overlap each other to form an overlapping portion 1221. Since the partition member 120 is composed of the first partition member 120A and the second partition member 120B as described above, the first partition member 120A and the second partition member 120B can be independently mounted, and thus the ease of assembly is improved. In addition, since the first partition member 120A and the second partition member 120B are assembled in such a manner that the upper portions 122 thereof overlap each other, it is possible to suppress the leakage of the filler M.

[0053] Referring to Figure 3 and Figure 6In this embodiment, the upper part 122 of the separator 120 has a contact portion 1222, which extends perpendicularly to the protrusion 1241 (shown in...). Figure 8 The upper part 122 of the partition 120 extends in the direction of the vehicle width (axial direction X) and contacts the central pillar reinforcing rib 118 of the vehicle body frame 110. Since the upper part 122 of the partition 120 contacts the central pillar reinforcing rib 118 of the vehicle body frame 110 through its contact portion 1222, the shaking of the partition 120 during the foaming of the filler M can be suppressed. In addition, the contact portion 1222 extends in the vehicle width direction (axial direction X) and contacts the central pillar reinforcing rib 118 of the vehicle body frame 110, so that the contact portion 1222 can serve as a guide structure when assembling the partition 120, making assembly easier.

[0054] Please refer to Figure 2 In this embodiment, the inner side of the central column inner component 116 is as follows: Figure 2 The upper part 122 of the partition 120 shown has an opening 116b. Figure 3 At least partially located below the opening 116b, and the lower portion 124 of the partition 120 as... Figure 3 The inner and outer parts 1121 of the side beam 112 are formed along the upper surface of the side beam 112. Accordingly, even if the filler M is filled inside the cross section of the central column 110, it is possible to prevent the foamed filler M from overflowing from the opening 116b inside the central column inner part 116.

[0055] In summary, in the vehicle body side structure of this utility model, the partition forms a filling space between its upper and lower parts, and the upper and lower parts are connected to each other through a connecting part. When the filler foams within the filling space, the upper part is pushed upward by the foamed filler, and the lower part is pushed downward by the foamed filler. The upward force and downward force of the foamed filler cancel each other out, effectively preventing displacement of the partition. Therefore, simply providing a protrusion at the lower part of the partition for insertion into the vehicle body frame is sufficient to prevent the partition from shifting during filler foaming, without the need for a complex locking structure such as a claw-shaped structure to lock the partition. Thus, the vehicle body side structure of this utility model can prevent partition displacement through a simple structural assembly of the partition.
