[0043] The upper part of the middle cross beam 122 is welded to the rear side panel 11, and the lower part of the middle cross beam 122 is bonded to the rear side panel 11 through a shock-absorbing sealant. The combination of welding and bonding can ensure the overall strength and rigidity of the rear side panel 1 and improve the NVH of the whole vehicle.

[0044] See also Figure 1-Figure 8 The body side also includes a side front portion 2, which is respectively connected to the rear side outer panel and the B-pillar 124.

By using the first C-pillar 125 and the second C-pillar 126, the problems of too long side panels, less support in the middle and weak structure can be solved.

[0049] The first C-pillar component 125 includes a first upper reinforcing plate 1251, a first lower reinforcing plate 1252 and a second lower reinforcing plate 1253. The upper end and the lower end of the first upper reinforcing plate 1251 are respectively welded to the upper cross beam 121 and the middle cross beam 122, the upper end and the lower end of the first lower reinforcing plate 1252 are respectively welded to the middle cross beam 122 and the lower cross beam 123, the upper end and the lower end of the second lower reinforcing plate 1253 are respectively welded to the middle cross beam 122 and the lower cross beam 123, and the second lower reinforcing plate 1253 is located between the first lower reinforcing plate 1252 and the D-pillar component 128.

[0052] The four force transmission paths, namely the first force transmission path 201 , the second force transmission path 202 , the third force transmission path 203 and the fourth force transmission path 204 , can significantly improve the force problem of the rear side panel inner panel assembly 12 and significantly enhance the rigidity of the entire rear side panel assembly.

[0053] The middle part of the second upper reinforcing plate 1261, the middle part of the third lower reinforcing plate 1262 and the middle part of the fourth lower reinforcing part are all bonded to the rear side panel 11 by means of shock-absorbing sealant. The combination of welding and bonding can ensure the overall strength and rigidity of the rear side panel 1 and improve the NVH of the whole vehicle.
