The third bend is connected to the second bend 231 to form an X-direction overlap, further improving the vehicle's handling stability.

[0044] The existing commercial vehicle roof rear crossbeam does not have a through-type rear crossbeam outer plate, so it cannot form a cavity structure with the inner plate. Moreover, it only overlaps with the side extension structure in the Y and Z directions, resulting in fewer stress surfaces and poor local torsional stiffness.

[0045] Reference Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, Figure 6 for Figure 3 Cross-sectional view at point BB. Figure 7 This is a top-view structural diagram of the vehicle provided in an embodiment of this application. Figure 8 for Figure 7 A cross-sectional view at point CC. The inner panel 11 of the rear crossbeam of the roof also includes a second extension 111 extending along the length direction of the vehicle body. The rear crossbeam assembly 1 of the roof also includes an outer panel 12 of the rear crossbeam of the roof. The outer panel 12 of the rear crossbeam of the roof includes a third extension 120 extending along the length direction of the vehicle body and a fourth extension 121 extending along the width direction of the vehicle body. The third extension 120 is connected to the second extension 111, and the fourth extension 121 is connected to the reinforcing plate body 31, so that the outer panel 12 of the rear crossbeam of the roof, the inner panel 11 of the rear crossbeam of the roof, and the tailgate hinge reinforcing plate 3 enclose and form a third cavity 13.

[0046] This embodiment includes a rear crossbeam outer plate 12, which together with the rear crossbeam inner plate 11 and the tailgate hinge reinforcement plate 3 to form a third cavity 13, which can absorb impact force during a collision and protect the safety of passengers. The rear crossbeam outer plate 12 overlaps with some structures of the side assembly 2 in the X, Y, and Z directions through the tailgate hinge reinforcement plate 3 welded to it, which increases the stress area, ensures local torsional stiffness, and thus improves the overall strength of the vehicle body.

[0047] Reference Figure 1 and Figure 2 As shown, the existing rear side panel reinforcement plate has a 500'Y extension length that is too short (only about 150mm), and the overlap area between the D-pillar reinforcement plate and its reinforcement plate and the tailgate hinge reinforcement plate is too small, making it impossible to form a continuous cavity. This results in poor structural force transmission performance and insufficient torsional rigidity of the entire upper part of the tailgate frame.

[0048] Reference Figure 4 As shown, the rear side panel reinforcement plate 22 includes a rear side panel reinforcement plate body 220 and a sixth connecting part 221 extending along the width direction of the vehicle body. The rear side panel reinforcement plate body 220 is connected to the reinforcement plate body 210, and the sixth connecting part 221 is connected to the first connecting part 211, so that the rear side panel reinforcement plate 22, the tailgate hinge reinforcement plate 3 and the D-pillar reinforcement plate 23 enclose and form a fourth cavity 222.

[0049] In this embodiment, the rear side panel reinforcement plate 22 extends to connect with the inner plate 11 of the rear crossbeam of the roof, greatly increasing the Y-direction extension length (by about 160 mm). The width of the rear side panel reinforcement plate 22, the tailgate hinge reinforcement plate 3, and the rear side panel reinforcement plate reinforcement plate 21 is increased. Together with the inner plate 11 of the rear crossbeam of the roof and the outer plate 12 of the rear crossbeam of the roof, they form multiple "intermittent nested" cavity structures (first cavity 33, second cavity 232, third cavity 13, and fourth cavity 222) near the joint area. With the overall weight basically the same, the rhomboid deformation of the tailgate frame is reduced by about 27%, and the vertical stiffness of the tailgate is directly increased by 15%, thereby improving the overall strength of the vehicle body.

[0050] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
