The rear cross beam outer plate 11 is provided with a mounting groove 101. The limiting bracket 12 is fixedly connected in the mounting groove 101. A guide area 102 is formed between the limiting bracket 12 and a groove bottom 1011 of the mounting groove 101. The fixed end 131 of the tailgate hinge 13 is arranged in the guide area 102 and fixedly connected to the rear cross beam outer plate 11. The tailgate hinge 13 is used to fix the tailgate to the rear cross beam outer plate 11. The groove bottom 1011 of the installation groove 101 is provided with two first fixing holes 107, and the fixed end 131 of the tailgate hinge 13 is provided with two second fixing holes 108. When the tailgate hinge 13 is installed, the fixed end 131 of the tailgate hinge 13 is guided by the guide area 102 so that the second fixing holes 108 are aligned with the first fixing holes 107, and two bolts are used to pass through the first fixing holes 107 and the second fixing holes 108 in sequence to fix the fixed end 131 of the tailgate hinge 13 on the rear cross beam outer plate 11. Since the fixed end 131 is arranged in the guide area 102, the limiting bracket 12 limits the fixed end 131 in the Z direction, and the Z direction refers to the height direction of the vehicle body; wherein, after the tailgate hinge 13 is installed, the limiting bracket 12 is arranged between the two second fixing holes 108. In this embodiment, two mounting grooves 101 are provided.

The third arc portion 125 is fixedly connected to an end of the guide portion 122 away from the second arc portion 124. The third arc portion 125 is arranged between the guide portion 122 and the straight plate portion 126. The third arc portion 125 provides a guiding function for the fixed end 131 of the tailgate hinge 13.

[0033] like Figure 1 As shown, the rear cross beam outer plate 11 includes a first connecting plate 111, a second connecting plate 112 and a third connecting plate 113, the first connecting plate 111 and the third connecting plate 113 are arranged opposite to each other, the second connecting plate 112 is fixedly connected between the first connecting plate 111 and the third connecting plate 113, the mounting groove 101 is arranged on the first connecting plate 111, and the rear cross beam assembly also includes a support block (not shown in the figure), when the tailgate hinge 13 is installed, the support block is detachably arranged on the third connecting plate 113, the support block is used to support the hinge end 132 of the tailgate hinge 13, so that when the tailgate hinge 13 is installed, the tailgate is in a fixed and stable state, which is convenient for the installation, adjustment and tightening of the tailgate hinge 13.

[0034] like Figure 3 and Figure 4 As shown, the distance between the guide surface 1221 and the bottom 1011 of the installation groove 101 is less than the thickness of the fixed end 131 of the tailgate hinge 13. It can be understood that there is an interference fit of 3 mm between the fixed end 131 of the tailgate hinge 13 and the guide surface 1221 of the guide portion 122 to avoid displacement of the tailgate hinge 13 in the Z direction during installation.

[0035] like Figure 1 and Figure 2 As shown, the first connecting plate 111 includes a top surface 111a, which is used to fix the skylight glass 20. The curvature of the top surface 111a is the same as the curvature of the skylight glass 20, that is, the arc surface of the top surface 111a is consistent with the arc surface of the skylight glass 20; the top surface 111a is provided with a glue coating area, the extension direction and length of the glue coating area match the edge of the skylight glass 20, the glue coating area is used to apply glass glue for fixing the skylight glass 20, and the cross-sectional width of the glue coating area is 20mm~30mm, preferably 24mm; when assembling the whole vehicle, the skylight glass 20 falls on the top of the vehicle body, and the skylight glass 20 is installed and matched with the rear crossbeam assembly. Considering factors such as the air tightness and water leakage of the vehicle body, glass glue is applied in the glue coating area, and the cross-sectional width of the glass glue is 24mm, which meets the requirements of installation, fastening, sealing and waterproofing of the skylight glass 20.

[0036] Please continue to refer to Figure 1 The first connecting plate 111 is provided with two positioning holes 105 , and the two positioning holes 105 are symmetrically arranged. When the skylight glass 20 is installed, the positioning holes 105 are used to position the skylight glass 20 .

[0038] Preferably, the first connecting plate 111 is further provided with a through hole 106 . When the rear cross beam assembly is installed or repaired, a storage rack can be placed on the through hole 106 for positioning. The storage rack is used to store tools such as screws or wrenches. Two through holes 106 are provided.

[0039] Installation principle: When the tailgate is installed, the tailgate hinge 13 is assembled with the tailgate and then installed on the vehicle body. The fixed end 131 of the tailgate hinge 13 is placed in the installation groove 101, and then the fixed end 131 is pushed forward along the X direction through the third arc portion 125 of the limiting bracket 12 and the guide surface 1221. The X direction refers to the length direction of the vehicle body, that is, the fixed end 131 of the tailgate hinge 13 is pushed toward the direction close to the fixing portion 121 of the limiting bracket 12, so that the first fixing hole 107 and The second fixing hole 108 is coaxial, and then a bolt is used to pass through the first fixing hole 107 and the second fixing hole 108. During the installation of the bolt, the support block is placed on the third connecting plate 113, and the support block is located at the root of the hinge end 132 of the tailgate hinge 13 to ensure that the tailgate is in a stable state, which is convenient for the installation, adjustment and tightening of the tailgate hinge 13.
