[0041] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0042] Example 1

[0043] Figure 1 The diagram shown is a simplified structural diagram of a floor provided in one embodiment of this application; Figure 2 What is shown is Figure 1 AA section view; Figure 3 What is shown is Figure 1 BB section view; Figure 4 What is shown is Figure 1 CC section view; please refer to Figures 1-4 .

[0044] This embodiment provides a floor 100, including an upper panel 110 and a lower panel 120 disposed opposite to each other, a filling layer 130 disposed between the upper panel 110 and the lower panel 120, and a plurality of reinforcing ribs 140; the filling layer 130 is filled between the upper panel 110 and the lower panel 120, and the filling layer 130 is used for heat insulation and sound insulation; the two ends of the reinforcing ribs 140 are fixedly connected to the upper panel 110 and the lower panel 120 respectively, and the plurality of reinforcing ribs 140 are evenly disposed in the filling layer 130.

[0045] The floor 100 of this embodiment, having an upper panel 110 and a lower panel 120, and with multiple reinforcing ribs 140 between the upper panel 110 and the lower panel 120, has higher strength and better load-bearing capacity compared to single-layer flooring in related technologies. Furthermore, the floor 100 of this embodiment also has a filling layer 130 between the upper panel 110 and the lower panel 120, which provides good thermal insulation and sound insulation, thus giving the floor 100 excellent thermal insulation and sound insulation performance.

[0046] Because the floor 100 in this embodiment has high strength and load-bearing capacity, the area of ​​each floor 100 can be larger than that of aluminum flooring in related technologies, thereby reducing the total number of floor panels in the carriage, which in turn reduces the amount of sealant used and reduces workload.

[0047] Optionally, in this embodiment, the upper panel 110 and the lower panel 120 are preferably made of steel plates (e.g., cold-rolled stainless steel plates), thereby giving the upper panel 110 and the lower panel 120 high strength. The surface of the upper panel 110 facing away from the lower panel 120 is provided with anti-slip textures to improve surface friction and prevent passengers from slipping. The filling layer 130 is preferably a sound-insulating and heat-preserving cotton layer. The reinforcing rib 140 can be stamped from steel plates, and the specific structure can be determined as needed. The reinforcing rib 140 is welded and fixed to the upper panel 110 and the lower panel 120.

[0048] Furthermore, in this embodiment, the thickness of the upper panel 110 is greater than or equal to 4 mm, the thickness of the lower panel 120 is greater than or equal to 2 mm, and the thickness of the filling layer 130 is greater than or equal to 20 mm, thereby ensuring that the floor 100 has high strength and good support performance, as well as good thermal insulation and sound insulation performance. The surface of the reinforcing rib 140 is provided with an anti-corrosion layer, thereby extending the service life of the floor 100.

[0049] Optionally, the upper panel 110 of this embodiment is further provided with at least one drainage groove 111, which is located above the reinforcing rib 140 to ensure local strength. At least one drain outlet is provided on the bottom surface of the drainage groove 111. The reinforcing rib 140 and the lower panel 120 are respectively provided with a first through hole and a second through hole corresponding to the drain outlet. One end of the drain pipe 150 is connected to the drain outlet, and the other end passes through the first and second through holes and extends to the outside of the floor 100. Water on the floor 100 can flow into the drain pipe 150 through the drainage groove 111, and then be discharged outside the vehicle or into a corresponding wastewater collection device, ensuring the cleanliness of the floor and preventing corrosion, thus extending its service life.

[0050] Preferably, in this embodiment, the drain pipe 150 is welded and fixed to the drain outlet, the diameter of the drain pipe 150 is greater than or equal to 22mm, and the wall thickness of the drain pipe 150 is greater than or equal to 2mm.

[0051] Furthermore, the floor 100 of this embodiment is provided with a flange structure around its perimeter, and the flange structure is provided with a plurality of fixing holes for connecting to fixing holes on the vehicle body or adjacent floor 100.

[0052] Specifically, the flange structure includes a first flange 112 connected to the upper panel 110 and a second flange 121 connected to the lower panel 120. The first flange 112 extends in a direction away from the lower panel 120, and the second flange 121 extends in a direction towards the upper panel 110. The first flange 112 and the second flange 121 are fixedly connected (e.g., welded), and the end of the second flange 121 away from the lower panel 120 is flush with the end of the first flange 112 away from the upper panel 110.

[0053] The height of the flange structure can be set as needed, generally not exceeding 15mm, to ensure normal passenger passage and prevent passengers from tripping. The flange structure ensures that wastewater will not flow into the floor 100 during floor cleaning, thus preventing the filling layer 130 from corroding or the lower panel 120 from rusting, thereby ensuring that the vehicle body structure is not corroded.

[0054] Example 2

[0055] Figure 5 The diagram shown is a partial structural schematic of a carriage according to an embodiment of this application; please refer to... Figure 5 .

[0056] This embodiment provides a carriage, including a vehicle body, and the vehicle body is provided with multiple interconnected floor panels, wherein the floor panels are floor 100 as described in Embodiment 1 above.

[0057] Figure 5 The diagram shows a partial structure inside the carriage, which includes four floor panels 100 and an equipment cabinet 18 between the four floor panels. The four floor panels 100 are connected to different parts of the vehicle body (including the end wall 15, side wall 16, and partition wall 17) on all four sides.

[0058] Figure 6 The diagram shown is a simplified representation of the connection structure between two adjacent floorboards according to an embodiment of this application. Figure 7 The diagram shown is a simplified representation of the connection structure between the floor and the wall according to an embodiment of this application.

[0059] Figure 8 The diagram shown is a simplified representation of the connection structure between the floor and the equipment cabinet base according to an embodiment of this application. Please refer to... Figures 6-8 .

[0060] Figures 6-8The diagram illustrates the connection structure between the floor 100 and the vehicle body. Specifically, in this embodiment, the vehicle body is equipped with a metal floor 11, on which a floor bracket 12 is mounted. A ground beam 13 is fixed to the side of the floor bracket 12 facing away from the metal floor 11, and the side of the ground beam 13 facing away from the metal floor 11 is connected to the floor 100. A first adjusting pad 14 is provided between the floor bracket 12 and the ground beam 13 for leveling. A first fastener passes sequentially through the floor bracket 12, the first adjusting pad 14, and the ground beam 13 to securely connect the floor bracket 12, the first adjusting pad 14, and the ground beam 13. The first fastener can be configured as needed; in this embodiment, the first fastener includes bolts, washers, and nuts. A shock-absorbing pad is provided between the ground beam 13 and the floor 100 to prevent damage to components caused by friction between the floor 100 and the ground beam 13.

[0061] Please continue to refer to Figure 6 In this embodiment, a wooden frame 210 is provided between two adjacent floorboards 100. The wooden frame 210 is fixed to the ground beam 13 by a second fastener, and the fixing holes on the floorboards 100 are fixedly connected to the wooden frame 210 by a third fastener.

[0062] A cover 220 is provided between the two floorboards 100. The cover 220 includes a shielding surface and a fixing surface connecting the two sides of the shielding surface. The shielding surface is located above the wooden frame 210 and the two flange structures. The two sides of the shielding surface extend to the upper panel 110 of the two floorboards 100 respectively. One side of the fixing surface is connected to the shielding surface, and the other side of the fixing surface abuts against the upper panel 110 of the floorboard 100. The shielding surface and the wooden frame 210 are fixedly connected by a fourth fastener.

[0063] In this embodiment, the surface of the wooden frame 210 is treated with anti-corrosion and flame retardant methods. The height of the wooden frame 210 is no higher than the height of the flanged structure. The slightly protruding wooden frame 210 and the flanged structure ensure that wastewater from cleaning the floor can smoothly enter the drainage groove 111 on the floor surface without overflowing. By setting the wooden frame 210, wear caused by direct contact between two adjacent floorboards 100 is avoided, and damage to the floorboards 100 due to uneven expansion and contraction caused by thermal expansion and contraction is also avoided. The snap-fit ​​cover 220 between the two floorboards 100 not only prevents dust and wastewater from entering the floor, but also reduces the use of sealant, saving resources and protecting the environment, while ensuring a uniform and aesthetically pleasing appearance. The second, third, and fourth fasteners can all be selected according to actual needs, such as screws or bolts.

[0064] Furthermore, in this embodiment, second adjusting pads 230 are provided between the ground beam 13 and the wooden frame 210, between the floor 100 and the wooden frame 210, and between the shielding surface and the wooden frame 210. The second adjusting pads 230 can adjust the gap between two adjacent parts to meet the installation requirements. The side where the fixed surface connects to the shielding surface is curved to prevent passengers from tripping when passing through.

[0065] Please continue to refer to Figure 7 , Figure 7 The connection between the floor 100 and the vehicle body end wall 15 is shown. The connection between the floor 100 and the vehicle body side wall 16 and partition wall 17 is the same as described above.

[0066] like Figure 7 As shown, in this embodiment, the fixing holes on the floor 100 are fixedly connected to the wall via a fifth fastener. For waterproofing, dustproofing, and overall aesthetics, a shielding component 240 is also provided between the floor 100 and the wall. The shielding component 240 includes a first shielding surface, a second shielding surface, and a third shielding surface that are interconnected. The first and third shielding surfaces are respectively perpendicularly connected to the two ends of the second shielding surface. The first shielding surface is connected to the wall via a sixth fastener. The second shielding surface is positioned above the flanged structure, and the third shielding surface abuts against the upper panel 110 of the floor 100. The shielding component 240 also serves a similar function to the cover 220, preventing dust and sewage from entering the floor, reducing the use of sealant, saving resources, and ensuring a uniform and aesthetically pleasing appearance. Both the fifth and sixth fasteners can be selected according to actual needs, such as screws or bolts.

[0067] Please continue to refer to Figure 8 In this embodiment, the vehicle body is also provided with an equipment cabinet 18. The equipment cabinet 18 is installed on the iron floor 11 through the equipment cabinet base 181. A third adjustment pad 250 is provided between the floor 100 and the equipment cabinet base 181. The distance between the floor 100 and the equipment cabinet base 181 is adjusted by the third adjustment pad 250 so that the seventh fastener can pass through the fixing hole, the third adjustment pad 250 and the equipment cabinet base 181 in sequence to fix the three together.

[0068] Furthermore, a shielding component 240 is also provided between the floor 100 and the equipment cabinet base 181. The first shielding surface is connected to the equipment cabinet base 181 via an eighth fastener, the second shielding surface is positioned above the flanged structure, and the third shielding surface abuts against the upper panel 110 of the floor 100. The shielding component 240 and the flanged structure on the floor not only prevent dust and sewage from entering the floor but also reduce the use of sealant, saving resources and protecting the environment, while ensuring a uniform and aesthetically pleasing appearance. In this embodiment, the seventh and eighth fasteners can be selected according to actual needs, such as screws or bolts. The above structure ensures that the floor 100 will not deform due to the shaking of the equipment cabinet 18, and the sound insulation and noise reduction material of the floor 100 minimizes the noise from the equipment operating inside the equipment cabinet 18, ensuring the comfort of passengers in the carriage.
