Through the arrangement of the above-mentioned mounting interfaces, the floor and the vehicle body chassis are detachably fixedly connected, and can be modularly arranged, which is simple in structure, convenient to install, widely applicable, and suitable for non-container freight bulk and luggage vehicles.

[0053] As shown in Figure 8 and 11 , specifically, the floor mounting module 3 comprises:

[0054] The mounting profile 31 has a hollow cavity, and the top surface of the mounting profile 31 is used to contact the bottom surface of the floor. The mounting profile 31 is detachably fixedly connected with the vehicle body mounting seat 1 through threaded fasteners.

[0055] The reinforcing plate 32 is located in the hollow cavity and is detachably fixedly connected with the mounting profile 31.

Specifically, the mounting profile 31 and the reinforcing plate 32 are tapped, and the threaded fasteners pass through the floor, the mounting profile 31 and the reinforcing plate 32 in sequence to realize the fixation.

[0056] The mounting profile 31 is preferably an aluminum alloy profile, and the reinforcing plate 32 is arranged in the mounting profile 31. The reinforcing plate 32 is preferably a carbon steel reinforcing plate 32. The mounting profile 31 has a hollow cavity, and the top surface of the mounting profile 31 is attached to the bottom surface of the floor. The mounting profile 31 is detachably fixedly connected with the vehicle body mounting seat 1 through threaded fasteners. The threaded fasteners pass through the bottom surface of the mounting profile 31 and the vehicle body mounting seat 1 to realize the detachable fixation. In order to adjust the machining error, an adjusting pad is arranged between the mounting profile 31 and the vehicle body mounting seat 1.

Specifically, the threaded fasteners pass through the floor, the mounting profile 31 and the reinforcing plate 32 to realize the fixation. It is preferred to use bolts to fasten after tapping the floor, the mounting profile 31 and the reinforcing plate 32. In this way, the floor and the vehicle body mounting seat 1 are connected through the mounting profile 31 and the reinforcing plate 32.

[0059] The strip-shaped mounting hole 311 compensates for machining and installation errors, and a threaded fastener is arranged in the strip-shaped mounting hole 311 to fix the mounting profile 31 to the vehicle body mounting seat 1; the threaded fastener specifically includes a bolt and a nut, as well as a gasket and other structures; in order to realize connection, an adjusting pad is arranged between the mounting profile 31 and the vehicle body mounting seat 1 to realize fixation. The two opposite side walls of the mounting profile 31 are provided with a plurality of groups of reinforcing plate mounting holes 312, and one reinforcing plate 32 corresponds to one group or two groups of reinforcing plate mounting holes 312; in this embodiment, the mounting profile 31 is provided with one reinforcing plate 32 at each longitudinal end, and each reinforcing plate 32 corresponds to two groups of reinforcing plate mounting holes 312, so that the mounting profile 31 is provided with two groups of reinforcing plate mounting holes 312 at each longitudinal end, and the reinforcing plate 32 and the mounting profile 31 are fixed through the reinforcing plate mounting hole 312.

[0060] It can be understood that the mounting profile 31 and the vehicle body mounting seat 1 are connected through a threaded fastener, the reinforcing plate 32 and the mounting profile 31 are connected through a threaded fastener, and then the reinforcing plate 32 and the floor are connected through a threaded fastener, so as to realize switching and ensure the connection strength of the two through the arrangement of the reinforcing plate 32.

It can be understood that each floor support module 2 on each freight floor module 4 is correspondingly arranged, and each floor mounting module 3 on each freight floor module 4 is correspondingly arranged, i.e., in the longitudinal direction of the vehicle body, each floor support module 2 of each freight floor module 4 is respectively arranged continuously in the longitudinal direction to ensure the transmission of the longitudinal force of the vehicle body, to better transmit the longitudinal load and meet the load design requirements of the railway vehicle.

[0072] Each freight floor module 4 is respectively provided with at least two floor support modules 2 and at least two floor mounting modules 3, preferably one floor mounting module 3 is symmetrically arranged on both sides of the center line in the length direction of the freight floor module 4, and four floor support modules 2 are symmetrically arranged at the same time; the two floor mounting modules 3 are arranged close to the center line; in other embodiments, the number of floor support modules 2 and floor mounting modules 3 can be arranged according to the length of the freight floor module 4, which is within the protection scope of the present application.

[0074] Each freight floor module 4 includes a corrugated sheet and an aluminum honeycomb interlayer, with a fiberglass sheet sandwiched between the corrugated sheet and the aluminum honeycomb interlayer. Specifically, the surface of the freight floor 100 is made of stainless steel corrugated sheet, with an aluminum honeycomb interlayer in the middle, and a fiberglass sheet sandwiched between the aluminum honeycomb interlayer and the stainless steel corrugated sheet to prevent electrochemical corrosion between the aluminum honeycomb and the stainless steel.

[0075] like Figure 12 As shown, specifically, to meet the floor design requirements of non-container type freight vehicles, any freight floor module 4 also includes a pull ring assembly 5 for securing cargo. The pull ring assembly 5 for securing cargo is provided on the freight floor 100. The freight floor module 4 has a pull ring mounting groove 41 that extends through the freight floor module 4 along its thickness direction. The new freight floor mounting structure also includes a pull ring mounting module 6. The bottom of the pull ring mounting module 6 rests on the vehicle body mounting seat 1, and the top is used for a detachable fixed connection with the freight floor module 4. The pull ring mounting module 6 corresponds to the pull ring mounting groove 41. The pull ring assembly 5 is located within the pull ring mounting groove 41 and is connected to the pull ring mounting module 6 and the vehicle body mounting seat 1 via threaded fasteners. The top surface of the pull ring assembly 5 is flush with the top surface of the freight floor module 4. The pull ring assembly 5 is located within the pull ring mounting groove 41 and is connected to the pull ring mounting module 6, the adjusting pad, and the vehicle body mounting seat 1 via threaded fasteners. Pull ring assemblies 5 are arranged in groups on the cargo floor module 4, specifically in two groups. The two groups of pull ring assemblies 5 are arranged longitudinally on the cargo floor module 4, and each group of pull ring assemblies 5 includes two pull ring assemblies 5 arranged opposite each other in the transverse direction; that is, four pull ring assemblies 5 are provided on each cargo floor module 4. In other embodiments, the number of pull ring assemblies 5 can be set according to the width and size of the cargo floor module 4. It can be understood that each pull ring assembly 5 of each cargo floor module 4 forms two longitudinal columns, and their arrangement is regular, which facilitates the support of cargo hooks.

[0076] The pull ring assembly 5 is disposed within the pull ring mounting groove 41, which corresponds to the pull ring mounting module 6 under the floor. A detachable and fixed connection between the pull ring assembly 5 and the vehicle body mounting base 1 is achieved through threaded fasteners. The pull ring assembly 5 is used to secure goods, providing an interface for cargo fixation. When the pull ring assembly 5 is not in use, its top surface is flush with the top surface of the cargo floor module 4 to avoid affecting the transfer and transportation of goods within the vehicle.

[0077] The pull ring component 5 specifically includes:

[0078] Pull ring 51;

[0079] Pull ring seat, pull ring 51 is rotatably connected inside the pull ring seat, and when the pull ring 51 is in the closed state, it is flush with the top surface of the pull ring seat;

[0080] The bottom mounting base 53 is located at the bottom of the pull ring seat, and the bottom mounting base 53 is detachably and fixedly connected to both the pull ring seat and the vehicle body mounting base 1.

[0081] The pull ring 51 is rotatably connected to the pull ring seat. The pull ring seat is provided with a rotating shaft. The rotating hole of the pull ring 51 cooperates with the rotating shaft to achieve a rotatable connection. When the pull ring 51 is located in the pull ring seat and is in the closed state, the top surface of the pull ring 51 is flush with the top surface of the pull ring seat. When the pull ring 51 needs to be opened, the pull ring 51 is rotated so that it rotates relative to the pull ring seat. The rotation angle is preferably 0° to 110°. To facilitate the installation of the pull ring assembly 5, the pull ring seat and the bottom mounting seat 53 are designed as separate structures, and the two are fixed with threaded fasteners. During installation, the bottom mounting seat 53 is first pushed through the pull ring mounting groove 41 on the cargo floor module 4 into the hollow cavity of the pull ring mounting module 6, and the bottom mounting seat 53 is fixed to the vehicle body mounting seat 1. Then, the pull ring seat is placed into the pull ring mounting groove 41, and the pull ring seat is fixed to the bottom mounting seat 53 with threaded fasteners. This completes the fixing of the pull ring assembly 5 on the cargo floor module 4 and the vehicle body frame. In this application, the pull ring assembly 5 uses the pull ring mounting module 6 as a new installation interface to fix it to the vehicle body frame. Its structure is ingenious and can ensure the firmness of the floor installation, while providing an interface for fixing goods.

[0082] The pull ring mounting module 6 is a pull ring mounting profile 61 with a hollow cavity. The bottom mounting seat 53 is located inside the hollow cavity of the pull ring mounting profile 61. The pull ring mounting profile 61 is attached to the bottom surface of the cargo floor module 4 and connected by threaded fasteners. The specific structure of the pull ring mounting profile 61 can be set with reference to the structure of the floor support 21. The pull ring mounting profile 61 and the vehicle body mounting seat 1 are connected by adjusting shims to fix the pull ring assembly 5 to the vehicle body mounting seat 1. Preferably, each cargo floor module 4 is provided with two sets of pull ring mounting profiles 61 symmetrically arranged along the center line, and each pull ring mounting profile 61 has a set of pull ring assemblies 5 at each of its longitudinal ends.

[0083] To improve the waterproof sealing of the floor, a wedge-shaped rubber sealing ring 54 is provided around the pull ring mounting groove 41 to cooperate with the pull ring assembly 5, so as to prevent sewage and other substances from flowing from the pull ring mounting groove 41 into the vehicle body underframe during floor cleaning and corroding the internal structure of the vehicle body.

[0084] Optionally, the bottom mounting base 53 is a "convex" shaped structure that is thick in the middle and thin at both ends. The two ends of the "convex" shaped structure are respectively provided with first pull ring mounting holes 531 for connecting with the vehicle body mounting base 1; the bottom of the pull ring mounting module 6 is provided with a second pull ring mounting hole 62 corresponding to the first pull ring mounting hole 531.

[0085] The two ends of the "hump" shaped structure extend longitudinally along the vehicle body, i.e. the two first pull ring mounting holes 531 are located at the longitudinal ends of the bottom mounting seat 53 for fixing with the vehicle body mounting seat 1; the "hump" shaped structure with thick middle and thin ends provides space for the installation of threaded fasteners, the threaded fasteners pre-installed in the vehicle body mounting seat 1 pass through the second pull ring mounting hole 62 and the first pull ring mounting hole 531 from bottom to top to fix the bottom mounting seat 53 and the vehicle body mounting seat 1; the threaded fasteners are preferably bolts.
