Therefore, the connection strength between the inner plate reinforcement plate 23 and the upper side beam assembly 10 can be ensured, and the inner plate reinforcement plate 23 is prevented from being separated from the upper side beam assembly 10.

[0035] For example, Figure 1 and Figure 2 As shown, the inner panel reinforcement plate 23 is connected to the upper side beam outer plate 11, and the inner panel reinforcement plate 23 is connected to the upper side beam inner plate 12.

Thus, the installation cavity 13 can facilitate the upper end of the inner plate reinforcement plate 23 to extend therein, thereby facilitating the connection between the inner plate reinforcement plate 23 and the upper side beam assembly 10.

[0037] According to some optional embodiments of the present invention, referring to Figure 1 and Figure 2 , the upper end of the inner plate reinforcement plate 23 (such as Figure 2 The upper end of the inner plate reinforcement plate 23 shown in the figure is provided with a left-right direction of the vehicle (such as Figure 1 The flange 233 extends into the installation cavity 13 and is connected to the upper side beam outer plate 11, and the lower end of the portion of the inner plate reinforcement plate 23 extending into the installation cavity 13 is connected to the upper side beam inner plate 12.

[0038] In this way, the flange 233 extends into the vehicle, which can facilitate the connection between the flange 233 and the upper side beam outer plate 11, thereby ensuring the connection strength between the inner plate reinforcement plate 23 and the upper side beam outer plate 11. At the same time, the flange 233 can increase the connection area with the upper side beam outer plate 11, thereby further ensuring the connection strength between the inner plate reinforcement plate 23 and the upper side beam outer plate 11. In addition, the inner plate reinforcement plate 23 is also connected to the upper side beam outer plate 11, thereby further increasing the connection strength between the inner plate reinforcement plate 23 and the upper side beam outer plate 11.

[0039] For example, Figure 1 and Figure 2 As shown, the upper end of the inner plate reinforcement plate 23 is provided with a flange 233 extending toward the interior of the vehicle, the upper side surface of the flange 233 is connected to the upper side beam outer plate 11, and the side surface of the lower end of the inner plate reinforcement plate 23 extending into the installation cavity 13 is connected to the upper side beam inner plate 12.

Thus, the connection strength between the B-pillar 20 and the roof rail assembly 10 can be further increased, so that the vehicle side reinforcement structure 100 can obtain good top pressure performance.

[0041] According to some optional embodiments of the present invention, referring to Figure 3 and Figure 4 , in the direction from bottom to top, the portion of the B-pillar 20 connected to the upper side beam assembly 10 is in the left and right direction of the vehicle (such as Figure 4 Due to the limitation of the shape of the vehicle side reinforcement structure 100, reducing the width of the B-pillar 20 can facilitate the connection between the B-pillar 20 and the upper side rail assembly 10.

[0042] According to some embodiments of the present invention, referring to Figure 3 and Figure 4 In the vertical direction, the length of the inner plate reinforcement plate 23 is greater than or equal to two-thirds of the length of the B-pillar inner plate 22. Thus, the inner plate reinforcement plate 23 can enhance the strength of the B-pillar 20, thereby ensuring the strength of the B-pillar 20.

[0043] For example, Figure 3 and Figure 4 As shown, the length of the inner panel reinforcement plate 23 may be two-thirds, three-quarters, or four-fifths of the length of the B-pillar inner panel 22 .

[0044] According to some embodiments of the present invention, referring to Figure 1 and Figure 4 The inner plate reinforcement plate 23 is arranged along the front-rear direction of the vehicle (eg Figure 1 The left and right directions shown) on both sides (such as Figure 1 The front and right sides of the inner plate reinforcement plate 23 shown in the figure are provided with a connecting edge, and a plurality of protrusions 234 are provided on the connecting edge.

When the top pressure performance test of the vehicle is performed, the cavity is divided into a plurality of sub-cavities, and the plurality of sub-cavities can redistribute the top pressure, so that the B-pillar 20 can bear a greater top pressure, and thus the vehicle can obtain good top pressure performance.

Figure 4 The second bent section 232 protrudes toward the B-pillar inner plate 22 in the middle of the front-to-back direction to form a second protrusion. The rear end of the second bent section 232 (as shown in FIG. Figure 4 The rear end of the second bent section 232 is connected to the B-pillar outer panel 21 and the B-pillar inner panel 22.
