[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] Please refer to the figure, this embodiment provides a threshold decorative plate installation structure for new energy vehicles, referring to Figure 1 The threshold outer trim 1 and threshold reinforcement plate 10 are made of PP+EPDM+T30 with a thickness of 2.8mm and are formed by injection molding. The deformation of the sample when pressed by external force is reduced to a certain extent, and the dent resistance is improved. The surface after injection molding is required to be flat and uniform, without defects such as bubbles, burrs and shrinkage marks. The surface is not allowed to have any defects that affect installation, function and appearance, such as deformation, warping, ripples, bright spots, wrinkles, cracks, stains or folds, separation of the covering layer, etc. The appearance surface is not allowed to be uneven.
[0020] The surface of the threshold outer panel 1 is provided with a leather grain layer and / or a spray coating, and the threshold outer panel body adopts leather grain + spray coating instead of split parts, which reduces mold development expenses, reduces matching, and reduces development costs.
[0021] The threshold outer trim panel 1 and the threshold reinforcement panel 10 are fixedly connected through multiple fixing points. Figure 2 As shown, the middle part of the threshold outer trim 1 is fixedly connected with the threshold reinforcement plate 10 by a buckle 2. The inner side of the threshold outer trim 1 is provided with a buckle surface by an integrally formed support rib 7. The corresponding positions of the buckle surface and the threshold reinforcement plate are both opened, and the buckle 2 is inserted and fixed at the opening. Figure 3As shown, the side of the threshold outer trim 1 and the threshold reinforcement plate 10 are connected by bolts 4, and the side of the bolt 4 extending into the threshold reinforcement plate 10 is fixed by nuts. A sealing gasket 3 is crimped at the through hole of the bolt 4.
[0022] The door sill outer trim panel 1 and the side panel outer trim panel are fixedly connected by using a limit card or a spring nut 5.
[0023] A foam support block 6 is embedded between the load-bearing area of the threshold outer trim panel 1 and the threshold reinforcement plate 10, thereby solving the appearance defects and achieving the supporting effect.
