A gap is formed between the interior floor 300 and the body floor 100, a plurality of vibration dampers 400 are provided in the gap, the vibration dampers 400 are conventional floor-supporting elastic vibration dampers, and the vibration dampers 400 abut between the interior floor 300 and the body floor 100, that is, the interior floor 300 is pressed against the vibration dampers 400, so that the vibration dampers 400 are fixed and at the same time, the vibration dampers 400 perform a vibration-damping supporting function of the vibration dampers 400 on the interior floor 300.

The embodiment adopts the mode that the two sides of the built-in floor 300 are compressed tightly and fixed, and the installation mode of the vibration damper 400 is optimized, while the floor performance is ensured, the number of fasteners when the built-in floor 300 is installed is reduced, the use of a large number of screw bolts is reduced, the installation efficiency of the built-in floor is improved, the installation cost and the material cost are reduced, various problems of looseness of fixing screws and the generation of bulge nails, vibration increase, abnormal sound and the like are fundamentally avoided, and the comfort level of passengers is effectively improved. The mode that this built-in floor 300 both sides compress tightly fixedly still considers floor anticreep function, avoids the floor to deviate from and produce the secondary damage when the extreme condition such as overturn appears in the vehicle.

As shown in fig. 2, in one embodiment, the pressing device 200 includes a mounting seat 220 and a pressing plate 230, the mounting seat 220 is mounted above both sides of the vehicle body floor 100, the pressing plate 230 is connected to the mounting seat 220, a pressing space 210 is formed between the pressing plate 230 and the mounting seat 220, and both ends of the interior floor 300 are pressed between the pressing plate 230 and the mounting seat 220.

In this embodiment, the height of the pressing plate 230 is adjustable, and when the floor is installed, both ends of the interior floor 300 are placed on the installation seats 220, and the pressing space 210 is compressed by adjusting the pressing plate 230 to fix the interior floor 300. When the floor is disassembled, the pressing plate 230 is disassembled, and the built-in floor 300 can be directly taken out, so that the operation is convenient, and the operation procedure is greatly simplified.

As shown in fig. 2, in one embodiment, the mounting base 220 has a first mounting surface 221 and a second mounting surface 222, the first mounting surface 221 and the second mounting surface 222 are both flat surfaces, the pressing plate 230 is horizontally mounted on the first mounting surface 221, one end of the pressing plate 230 extends above the second mounting surface 222, a space formed between the second mounting surface 222 and the pressing plate 230 is a pressing space 210, and an end of the interior floor 300 is pressed between the pressing plate 230 and the second mounting surface 222. The first mounting surface 221 ensures the stability of the connection of the pressing plate 230 with the mounting base 220, and the second mounting surface 222 provides a mounting position for the interior floor 300, ensuring the stability of the installation of the interior floor 300.

Further, a third mounting surface 223 is connected between the first mounting surface 221 and the second mounting surface 222, the third mounting surface 223 is a vertical plane, the first mounting surface 221, the second mounting surface 222, and the third mounting surface 223 are formed in a stepped shape, and when the interior floor panel 300 is lapped on the second mounting surface 222, an end side surface of the interior floor panel 300 can be brought into contact with the third mounting surface 223. Thus, the opposite installation seats 220 abut against both sides of the interior floor 300, so that the lateral displacement of the interior floor 300 can be effectively prevented, and the stability of the interior floor 300 is further improved.

As shown in fig. 2 and 3, in one embodiment, mount 220 is L-shaped. The installation base 220 is ensured to have the first installation surface 221, the second installation surface 222 and the third installation surface 223, meanwhile, the structure of the installation base 220 is simplified as much as possible, the cost is reduced, and the installation is convenient. The bottom of the mounting seat 220 also has a certain height requirement to ensure a height of a space between the interior floor 300 and the vehicle body floor 100, and to ensure the installation of the vibration damping device 400.
