In some embodiments, to ensure strength, the hinge connecting plate body 401 and the reinforcement plate 402 of the left tailgate hinge reinforcement plate 40 and the right tailgate hinge reinforcement plate 41 each have a thickness significantly greater than that of the coat rack sheet metal body 3, for example, a thickness of 1.2 mm to 1.8 mm. On the other hand, the coat rack sheet metal body 3, for the purpose of lightweighting, has a thickness of 0.7-1.0 mm.
[0038] In some embodiments, as Figure 4 As shown, the coat rack sheet metal assembly mainly supports the coat rack trim, so the coat rack sheet metal assembly can be provided with pre-fastened buckles 43 to facilitate the alignment and assembly of the various components, for example Figure 4The two pre-fasteners 43 on the middle sides facilitate the connection of the coat rack body to the side hinge reinforcement plates, and the two pre-fasteners 43 in the middle facilitate the connection of the rear windshield beam reinforcement plate to the coat rack body. In other embodiments, more pre-fasteners 43 may be provided. In some embodiments, such as in Figure 2 and Figure 4 As indicated in FIG, the coat rack sheet metal body 3 includes a plurality of through holes to achieve pressure relief through the coat rack sheet metal when the door is closed. In some embodiments, the coat rack sheet metal body 3 has a 28000mm 2 The effective opening area is above. In some embodiments, the coat rack sheet metal body 3 includes a long opening 31 along the width direction of the coat rack sheet metal body, and in at least one cross section, the width of the long opening 31 is at least 30 percent of the width of the coat rack sheet metal body 3 at that position. In some embodiments, the long opening 31 may have a convex shape. Providing a larger opening in the middle position of the coat rack sheet metal body 3 can effectively reduce vibration, improve NVH performance, and achieve lightweight and high permeability requirements. In some embodiments, the coat rack sheet metal body 3 is also provided with a wiring harness hole 32, a speaker mounting portion 33, a trunk light mounting portion 35, etc. It is worth noting that the mounting bolts of the seat belt retractor and the trunk light are facing upward to expand the trunk space.
