[0046] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0047] like Figures 1 to 12 As shown, the present invention provides a floor structure 10 according to a first aspect embodiment, including a base plate 100, a frame 102, and a panel 108; wherein, the frame 102 is mounted on the base plate 100, and the frame 102 is provided with reinforcing ribs 104 and sliding grooves 106 along the length of the vehicle, the reinforcing ribs 104 and the sliding grooves 106 being inclined relative to each other; the panel 108 covers the frame 102; wherein, the sliding grooves 106 and the reinforcing ribs 104 are used for installing in-vehicle equipment.

[0048] According to a first aspect of the present invention, a floor structure 10 is provided. By providing a slide groove 106 along the vehicle length direction in the frame 102, and a reinforcing rib 104 inclined to the slide groove 106, the equipment inside the vehicle can slide along the slide groove 106 along the vehicle length direction, thereby adjusting the position of the equipment inside the vehicle. The reinforcing rib 104 securely installs the equipment inside the vehicle, improving the stability of the equipment installation. This arrangement ensures flexible adjustment of the position of the equipment inside the vehicle and its secure installation. Furthermore, by providing the reinforcing rib 104 inclined to the slide groove 106, the strength of the vehicle body structure can be simultaneously improved along both the vehicle length and width directions, ensuring the stability of the vehicle body structure.

[0049] See also Figure 1 and Figure 3 The floor structure 10 is a composite structure, along such as Figure 3 The components shown, from bottom to top, are a base plate 100, a frame 102, and a panel 108. The base plate 100 is used to mount the frame 102 and the panel 108, and it can be mounted to the vehicle chassis using fasteners such as bolts.

[0050] Meanwhile, in order to achieve vibration reduction and noise reduction, a vibration damping device can also be installed between the base plate 100 and the vehicle chassis. The specific structure of the vibration damping device is not limited in detail in this embodiment of the invention.

[0051] A frame 102 is provided on the upper surface of the base plate 100. The frame 102 includes a frame that can surround the edge of the base plate 100. A reinforcing rib 104 and a sliding groove 106 are provided within the frame 102. The sliding groove 106 is arranged and extends along the length of the vehicle, i.e., the vehicle length direction... Figure 2 The left and right directions are shown. This arrangement allows the interior equipment to be adjusted along the length of the vehicle. The reinforcing rib 104 and the slide rail 106 are arranged at an angle relative to each other. It can be understood that the extending directions of the reinforcing rib 104 and the slide rail 106 are neither parallel nor perpendicular; that is, the angle between the direction of the reinforcing rib 104 and the extending direction of the slide rail 106 is greater than 0 degrees and less than 90 degrees.

[0052] In this embodiment of the invention, the angle between the arrangement direction of the reinforcing rib 104 and the extension direction of the groove 106 ranges from 25 degrees to 65 degrees.

[0053] By arranging the reinforcing ribs 104 at an inclined angle to the slide groove 106, the equipment inside the vehicle can be connected and fixed at the position of the reinforcing ribs 104 after sliding into place along the slide groove 106, thereby improving the installation stability of the equipment inside the vehicle. In addition, by arranging the reinforcing ribs 104 at an inclined angle, the strength of the floor structure 10 can be reinforced simultaneously in both the length and width directions of the vehicle.

[0054] Furthermore, it should be noted that in related technologies, the installation of in-vehicle equipment usually requires the additional installation of a secondary floor. In this embodiment of the invention, by providing a sliding groove 106 and a reinforcing rib 104 in the frame 102, the installation of a secondary floor can be eliminated, and the in-vehicle equipment can be directly installed on the sliding groove 106 and the reinforcing rib 104 in the frame 102, thereby reducing the production and maintenance costs of the floor structure 10.

[0055] like Figure 2 As shown, in this embodiment of the invention, there are multiple reinforcing ribs 104, and the distance between two adjacent reinforcing ribs 104 offset along the vehicle length direction ranges from 90 mm to 190 mm. This arrangement allows for the fulfillment of the installation requirements for in-vehicle equipment without excessively increasing the vehicle's weight, while also effectively ensuring the structural strength of the vehicle body.

[0056] According to one embodiment of the present invention, a magnetic element is embedded in the reinforcing rib 104.

[0057] In this embodiment of the invention, since a floor cloth is laid on the panel 108, and to avoid further adjustments to the floor cloth during the actual installation of the in-vehicle equipment, a magnetic component is installed inside the reinforcing rib 104. With this configuration, when the installer is installing the in-vehicle equipment, they can use a magnet or other magnetic attraction device to sense the specific location and direction of the reinforcing rib 104. As mentioned earlier, since the reinforcing rib 104 is long and narrow, after determining the position and tilt direction of the reinforcing rib 104 using a magnet, the in-vehicle equipment can simply be installed along the determined direction.

[0058] According to one embodiment of the present invention, it further includes a core material 110, which is disposed between the base plate 100 and the panel 108, and is embedded in the frame 102.

[0059] like Figure 3 As shown, in this embodiment of the invention, a core material 110 is further provided between the base plate 100 and the panel 108, wherein the core material 110 can be embedded in the frame 102. The function of the core material 110 is to reduce the weight of the floor structure 10 and also to reduce noise. For example, the core material 110 can be made of sound-absorbing cotton or similar materials. It should be noted that in this embodiment of the invention, the main structural strength of the floor structure 10 relies on the frame 102 and the reinforcing ribs 104; therefore, the core material 110 does not need to bear load and only needs to achieve the above-mentioned objectives.

[0060] According to one embodiment of the present invention, a seal 112 is detachably installed in the slide groove 106, and the seal 112 is used to seal the groove opening of the slide groove 106.

[0061] Please continue reading Figure 3In this embodiment of the invention, in order to prevent debris from entering the slide 106, a seal 112 can be installed in the slide 106 at the location where no in-vehicle equipment needs to be installed. The seal 112 can be a sealing strip, waterproof adhesive, etc.

[0062] A second aspect of the present invention provides a vehicle body, including in-vehicle equipment and the aforementioned floor structure 10, wherein the in-vehicle equipment is mounted on the floor structure 10.

[0063] According to the second aspect of the present invention, the vehicle body provided with the above-described floor structure 10 not only enriches the layout of the in-vehicle equipment, but also improves the structural strength of the vehicle body.

[0064] According to one embodiment of the present invention, the vehicle body further includes a support beam assembly, the support beam assembly including a base 114 and a mounting position 116; wherein, the base 114 is adapted to be slidably mounted on a slide groove 106 by fasteners; the mounting position 116 is connected to the base 114 and is used to connect in-vehicle equipment.

[0065] See Figure 1 , Figure 4 and Figure 5 In this embodiment of the invention, the support beam assembly is used to install in-vehicle equipment, such as partition 120, sliding door 124, etc.

[0066] Therefore, in order to achieve the above objectives, the support beam assembly mainly consists of a base 114 and a mounting position 116.

[0067] It is understandable that the base 114 and the slide 106 can be connected by fasteners. This design ensures that the base 114 can slide along the slide 106 to adjust to different mounting positions 116. Correspondingly, by integrating mounting positions 116 on the base 114, the installation and fixation of in-vehicle equipment can be achieved simultaneously. It should be noted that, in actual installation, the base 114 is preferably installed at the position where the slide 106 meets the reinforcing rib 104. This design not only allows for adjustment of the position of the in-vehicle equipment but also improves the connection stability between the in-vehicle equipment and the floor structure 10.

[0068] According to one embodiment of the present invention, the installation position 116 includes at least one of the following: a partition wall fixing position, an end door storage position, and an end wall fixing position.

[0069] See also Figures 8 to 12In this embodiment of the invention, the installation position 116 may include at least one of a partition wall fixing position, an end door storage position, and an end wall fixing position. This configuration enables modular installation of different devices such as the partition wall 120, end door, and end wall 122. In this embodiment of the invention, the installation functions of different devices such as the partition wall 120, end door, and end wall 122 are simultaneously integrated on the installation position 116.

[0070] like Figure 9 As shown, when the mounting position 116 includes a partition fixing position, the partition fixing position can be formed at the end edge of the support beam assembly, thereby enabling a large-angle partition 120 setting.

[0071] like Figure 10 As shown, when the installation position 116 includes the end door storage position, the end door storage position has a relatively large installation and storage space to realize the storage and installation of the end door.

[0072] like Figure 11 As shown, when the mounting position 116 includes the end wall fixing position, the end wall fixing position is used to install the end wall 122, which can simplify the connection structure of the end wall 122 and improve the installation stability of the end wall 122.

[0073] According to one embodiment of the present invention, there are at least two sets of mounting positions 116, and at least two sets of mounting positions 116 are disposed at intervals on the base 114. The base 114 between two adjacent sets of mounting positions 116 is formed with sliding positions 118 suitable for sliding engagement with the sliding groove 106.

[0074] like Figure 8 As shown, in this embodiment of the invention, the mounting positions 116 can be spaced apart along the length of the base 114. Taking two sets of mounting positions 116 as an example, a sliding position 118 is provided on the base 114 between the two sets of mounting positions 116. The sliding position 118 slides in conjunction with the sliding groove 106 in the frame 102. Thus, in actual use, the position of the support beam assembly can be adjusted through the sliding engagement of the sliding position 118 and the sliding groove 106.

[0075] like Figure 12 As shown, the cross-section of the sliding part 118 is roughly inverted T-shaped, which can improve the structural stability of the sliding part 118 and also achieve the purpose of lightweighting.

[0076] A third aspect of the present invention provides a rail vehicle, including the floor structure 10 described above, or the vehicle body described above.

[0077] According to the third aspect of the present invention, the rail vehicle provided can improve the convenience of interior adjustment by setting the floor structure 10 or the car body described above, and can also improve the structural strength of the rail vehicle in the length and width directions, so as to meet the requirements of safe operation.

[0078] The rail vehicle provided in the third aspect of the present invention can be a high-speed rail, urban rail, subway, etc.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
