[0035] refer to Figure 2 and Figure 5 An embodiment of the present invention provides a floor structure for a vehicle, comprising

[0036] The hollow plate 3 has a first side surface and a second side surface opposite to each other, and a partial hollow area is formed inside the hollow plate;

[0037] The elastic support 2 is fixed on the second side surface of the hollow plate 3. The area where the elastic support 2 contacts the hollow plate 3 is formed by an elastic material 23. Metal material is embedded in the elastic material 23, and the metal material embedded in the elastic material 23 extends out of the elastic material 23 to form a surface of the elastic support 2 facing away from the hollow plate 3. The elastic material 23 and the metal material in the elastic support 2 are an integrated structure.

[0038] In the floor structure, the hollow plate 3 helps to reduce the weight of the floor structure, and the elastic material 23 in the elastic support 2 has the functions of energy absorption and shock reduction, and impact protection, and the elastic material 23 is used to isolate the thermal bridge. Since the elastic material 23 and the metal material in the elastic support 2 are an integrated structure, the structure of the elastic support 2 is stable and reliable. The installation process of the floor structure is simple, and it only needs to fix the hollow plate 3 on the elastic material 23 through the second fastener 8 such as a self-tapping screw, and fix the metal material of the elastic support 2 on the vehicle body chassis 1 through the first fastener 7 such as a screw.

[0039] Optionally, refer to Figure 3 The hollow plate 3 includes an upper plate 31, a middle plate 32 and a lower plate 33 stacked in a direction from the first side surface to the second side surface thereof, and the local hollow area in the hollow plate 3 is located in the middle plate 32.

[0040] The material of the upper plate 31 is, for example, 5 series aluminum alloy, with a thickness of 1 to 1.5 mm. The middle plate 32 is, for example, an aluminum alloy honeycomb plate, a paper honeycomb plate or a foam plate. The material of the lower plate 33 is, for example, 5 series or 7 series aluminum alloy, with a thickness of 2 to 5 mm.

[0041] The thickness of the lower plate 33 is greater than that of the upper plate 31, and the lower plate 33 plays a major supporting role. The middle plate 32 has a hollow area, which helps to reduce the deadweight of the floor structure.

[0042] Optionally, refer to Figure 4 , the number of the hollow plates 3 is multiple;

[0043] At the edge area of ​​the first hollow plate 3a of the two adjacent hollow plates 3 facing the second hollow plate 3b, the local thickness area of ​​the upper plate 31 and the middle plate 32 close to the upper plate 31 is vacant, and the second metal plate 6 is embedded in the local area of ​​the middle plate 32 close to the lower plate 33, the strength and hardness of the second metal plate 6 are greater than the strength and hardness of the middle plate 32, and the orthographic projection of the second metal plate 6 on the plane where the hollow plate 3 is located overlaps with the orthographic projection of the upper plate 31 on the plane where the hollow plate 3 is located and overlaps with the vacant area of ​​the upper plate 3;

[0044] At the edge area of ​​the second hollow plate 3b of the two adjacent hollow plates 3 facing the first hollow plate 3a, the local thickness area of ​​the lower plate 33 and the middle plate 32 close to the lower plate 33 is vacant;

[0045] The local thickness areas of the upper plate 31 and the middle plate 32 of the second hollow plate 3b close to the upper plate 31 are overlapped on the local thickness areas of the lower plate 33 and the middle plate 32 of the first hollow plate 3a close to the lower plate 33, and the two are fixedly connected by a third fastener 9 that passes through the overlapping area, and the third fastener 9 passes through the second metal plate 6.

[0046] The third fastener 9 is, for example, a self-tapping screw. The second metal plate 6 makes the installation of the two adjacent hollow plates 3 more secure, and the hollow plates 3 can withstand the shock wave below without causing the two hollow plates 3 to tear apart at the overlap.

[0047] The present invention has no special limitation on the shape and size of the third metal plate 5. For example, the third metal plate 5 can be a square plate with a side length of 5 cm or other suitable sizes and shapes.

[0048] Further references Figure 4 , along the direction perpendicular to the overlapping boundary of the two hollow plates 3 ( Figure 4 In the left-right direction), the size of the vacant area of ​​the second hollow plate 3b is larger than the size of the vacant area of ​​the first hollow plate 3a.

[0049] This ensures that when the first hollow plate 3a and the second hollow plate 3b are overlapped, the overlap gap on the upper surface can be approximately ignored. The upper surface of the hollow plate 3 as a whole is a flat and complete surface.

[0050] Continue to refer Figure 4 The floor structure further includes an adjustment pad 6 which is arranged in the overlapping area of ​​the first hollow plate 3a and the second hollow plate 3b and is located between the two first hollow plates 3a and the second hollow plates 3b at the overlapping area.

[0051] The material of the adjustment pad 6 is rubber, for example, and the adjustment pad 6 plays a leveling role.

[0052] Optionally, refer to Figure 5 , Figure 6 Combined with Figure 1 The elastic support 2 has a length direction and a width direction that are perpendicular to each other, and both the length direction and the width direction are parallel to the plane where the hollow plate 3 is located. Figure 1 The left and right direction in FIG. 2 is the width direction of the elastic support 2 .

[0053] The elastic support 2 comprises:

[0054] The elastic material 23, whose surface close to the hollow plate 3 is an upper supporting plane 233, is provided with two first U-shaped openings 231 opposite to each other in the width direction and two second U-shaped openings 232 opposite to each other in the width direction in the elastic material 23 on the side of the upper supporting plane 233 facing away from the hollow plate 3, the first U-shaped opening 231 and the second U-shaped opening 232 both penetrate the elastic material 23 in the length direction, the first U-shaped opening 231 is located on the side of the second U-shaped opening 232 away from the upper supporting plane 233, and the elastic material 23 is vacant between the two first U-shaped openings 231 and between the two second U-shaped openings 232, and the vacant areas are connected as one;

[0055] The first metal plate 22 is embedded in the two second U-shaped openings 232;

[0056] The metal profile 21 is embedded in the two first U-shaped openings 231 , and has a hardness and a density that are smaller than those of the first metal plate 22 .

[0057] The material of the metal profile 21 is, for example, 7 series aluminum alloy. The material of the first metal plate 22 is, for example, steel. The material of the elastic material 23 is, for example, rubber. In this way, the elastic support 2 is lightened in overall weight and has a certain elasticity.

[0058] For example, the metal profile 21 and the vulcanized rubber are vulcanized as a whole to form an integral fixed structure; when the vulcanized rubber is being formed, the first metal plate 22 is pre-placed therein in advance, and the vulcanized rubber is the elastic material 23 .

[0059] Optionally, refer to Figure 2 and Figure 5 The metal profile 21 has a protruding area extending beyond the first metal plate 22 and the elastic material 23 in the length direction, and a through hole 211 is provided in the protruding area for connecting the metal profile 21 to the vehicle body chassis 1.

[0060] For example, a first fastener 7 such as a screw is inserted through the through hole 211 to fix the metal profile 21 on the vehicle body underframe 1 .

[0061] Optionally, refer to Figure 2 The floor structure further includes a floor cloth 4 arranged on the first side surface of the hollow board 3.

[0062] Some embodiments of the present invention may provide a floor structure that can be installed inside a vehicle to provide basic equipment for the vehicle, thereby achieving lightweight floor structures, energy absorption and shock reduction, and simple installation, thereby improving the comfort level inside the vehicle. At the same time, it has a certain ability to protect against shock waves and can be widely used in railway vehicles, road vehicles, and special vehicles.

[0065] The vehicle is, for example, a railway vehicle, a road vehicle or a special vehicle.
