Description

Technical Field

[0001] This utility model relates to the field of rail vehicle technology, and in particular to rail vehicle side wall units. Background Technology

[0002] Rail vehicles are an important part of public transportation. The side walls of rail vehicles are usually made by welding two components: columns and beams. The process of lightweighting components reduces the wall thickness, which increases the difficulty of welding. If the weld is too large, it will damage the supporting structure of the component, and if the weld is too small, it will result in insufficient welding strength.

[0003] In the existing technology, when the side wall is subjected to external force, the pre-deformation of the column and the beam is different, which causes a tangential force to be generated at the welding position when the force is applied. The tangential force is more likely to damage the weld, resulting in an increase in the strength requirements of the welding position. Utility Model Content

[0004] The purpose of this invention is to provide a side wall unit for rail vehicles, which can reduce the impact on the welding position during the stress process, thereby reducing the requirement for welding strength and indirectly improving the overall structural strength.

[0005] This utility model provides a side wall unit for rail vehicles, comprising:

[0006] The columns are vertically arranged and spaced along a straight line in the longitudinal direction, and the columns are laterally bent.

[0007] A crossbeam is provided, which is arranged horizontally along the longitudinal direction and distributed at intervals along the column in the vertical direction. The crossbeam is welded to the side wall on the inner side of the curved side of the column.

[0008] The first contact block is disposed on the side wall of the inner side of the column bend. Each of the crossbeams is provided with the first contact block on both the upper and lower sides, and the first contact block abuts against the side wall of the crossbeam in the upper and lower directions.

[0009] When the column is subjected to force and tends to bend further, the first contact block will press against the side wall of the beam from both the top and bottom.

[0010] Preferably, a second contact block is provided on the crossbeam, the second contact block on the crossbeam is located on the side wall of the crossbeam near the column, and the second contact block on the crossbeam abuts against the two longitudinal side walls of the column.

[0011] Preferably, a first material discharge groove is provided on the side wall of the curved outer side of the column, and the cross-section of the column is concave.

[0012] Preferably, a first reinforcing rib is provided in the first material discharge trough along the cross-sectional direction of the column, and the position of the first reinforcing rib is aligned with the crossbeam.

[0013] Preferably, the second contact block includes a second contact plate and a second support rib. The second contact plate abuts against the side wall of the column, and the second support rib is arranged perpendicular to the second contact plate and its position is aligned with the first reinforcing rib.

[0014] Preferably, a second material discharge groove is provided on the side wall of the crossbeam away from the column, and the crossbeam has a concave cross-section.

[0015] Preferably, a second reinforcing rib is provided in the second discharge trough along the cross section direction of the beam, and the position of the second reinforcing rib is aligned with the column.

[0016] Preferably, the first contact block includes a first contact plate and a first support rib, the first contact plate abuts against the side wall of the crossbeam, and the first support rib is arranged perpendicular to the first contact plate and the position of the first support rib is aligned with the second reinforcing rib.

[0018] Preferably, the rail vehicle sidewall unit further includes an interior panel, which is fixedly connected to each of the crossbeams, and the sidewall of the interior panel is attached to the sidewall of the crossbeam away from the column.

[0019] The technical solution of this utility model controls the pre-deformation direction of the column under stress by using the bending characteristics of the column itself. By setting the first contact block on the column to clamp the crossbeam to share the impact force, the deformation of the column at the welding position after being stressed is suppressed, and the impact on the welding position during the stress process is reduced. Under the condition that the welding strength remains unchanged, the upper limit of the structure's stress is indirectly increased. Attached Figure Description

[0032] Combination Figures 1 to 6 As shown, the rail vehicle sidewall unit provided by this utility model includes a column 1, a crossbeam 2, a first contact block 3, and a second contact block 4.

[0033] Combination Figures 1 to 6 As shown,

[0034] The column 1 is set vertically and is distributed along a straight line in the longitudinal direction. The column 1 is bent in the transverse direction. A first material discharge groove 11 is opened on the side wall of the outer side of the bend of the column 1, so that the cross-section of the column 1 is concave. A first reinforcing rib 12 is provided in the first material discharge groove 11 along the cross-section direction of the column 1, so as to reduce the mass of the column 1 while ensuring its strength.

[0035] The crossbeam 2 is set horizontally along the longitudinal direction and is distributed at intervals along the bending trajectory of the column 1 in the vertical direction. The crossbeam 2 is welded to the side wall on the inner side of the bending of the column 1. A second material discharge groove 21 is opened on the side wall of the crossbeam 2 away from the column 1, so that the cross section of the crossbeam 2 is concave. A second reinforcing rib 22 is provided in the second material discharge groove 21 along the cross section direction of the crossbeam 2, which reduces the mass of the crossbeam 2 while ensuring its strength.

[0036] The first contact block 3 is set on the side wall of the inner side of the curved column 1. Each crossbeam 2 is provided with a first contact block 3 on both the upper and lower sides. The first contact block 3 abuts against the side wall of the crossbeam 2 in the upper and lower directions. The first contact block 3 includes a first contact plate 31 and a first support rib 32. The first contact plate 31 abuts against the side wall of the crossbeam 2. The first support rib 32 is set perpendicular to the first contact plate 31. The position of the first support rib 32 is aligned with the second reinforcing rib 22 to improve the structural strength of the connection position and avoid deformation problems.

[0037] The second contact block 4 is disposed on the crossbeam 2. The second contact block 4 on the crossbeam 2 is located on the side wall of the crossbeam 2 near the column 1. The second contact block 4 is provided on both sides of the longitudinal direction of each column 1, and the second contact block 4 on the crossbeam 2 abuts against the two side walls of the column 1 in the longitudinal direction. The second contact block 4 includes a second contact plate 41 and a second support rib 42. The second contact plate 41 abuts against the side wall of the column 1, and the second support rib 42 is disposed perpendicular to the second contact plate 41. The position of the second support rib 42 is aligned with the first reinforcing rib 12 to improve the structural strength of the connection position and avoid deformation problems.

[0038] Combination Figure 6 As shown, the metal shell 5 is fixedly connected to each column 1. The bolt connection is used in the figure to ensure the fixing effect. The side wall of the metal shell 5 is attached to the side wall of the curved outer side of the column 1 to ensure the support effect of the column 1 on the metal shell 5.

[0039] Combination Figure 6 As shown, the interior panel 6 is fixedly connected to each crossbeam 2. The installation process is simplified by using a snap-fit ​​connection. The side wall of the interior panel 6 is attached to the side wall of the crossbeam 2 away from the column 1 to ensure the support effect of the crossbeam 2 on the interior panel 6.

[0040] Work process: The column 1 is assembled on the rail vehicle with the outside of the rail vehicle and the crossbeam 2 is assembled on the inside of the rail vehicle.

[0041] When bearing vertical pressure, the column 1 directly bears the pressure. Since the column 1 is inherently curved, its bending deformation direction is fixed after being subjected to force. When the column 1 is subjected to force and tends to bend further, the first contact block 3 will squeeze the side wall of the crossbeam 2 from the top and bottom. The reaction force of the squeeze will suppress the deformation at the connection between the column 1 and the crossbeam 2, thus protecting the welding position.

[0042] In this embodiment, the pre-deformation direction of the column 1 under stress is controlled by the bending characteristics of the column 1 itself. By setting the first contact block 3 on the column 1 to clamp the crossbeam 2 to share the impact force, the deformation of the column 1 at the welding position after being stressed is suppressed, the impact on the welding position during the stress process is reduced, and the upper limit of the structure is indirectly increased while the welding strength remains unchanged.

[0043] When bearing horizontal pressure from the inside to the outside of the rail vehicle, the pressure is transmitted to the crossbeam 2 through the interior panel 6. When the pressure causes the crossbeam 2 to deform, the pressure is transmitted to the column 1 through the crossbeam 2, causing the position on the column 1 that connects to the crossbeam 2 to deform. This causes the first contact block 3 to press against the side wall of the crossbeam 2. The reaction force of the press will suppress the deformation at the welding position on the column 1, and at the same time, it will suppress the deformation at the welding position on the crossbeam 2, thus protecting the welding position.

[0044] When bearing horizontal pressure from the outside of the rail vehicle towards the inside, the pressure is transmitted to the column 1 through the metal shell 5. The column 1 is arched to resist the pressure. When the pressure causes the column 1 to deform, the pressure is transmitted to the crossbeam 2 through the column 1, causing the position on the crossbeam 2 connected to the column 1 to deform. This causes the second contact block 4 to squeeze the side wall of the column 1. The reaction force of the squeeze will suppress the deformation at the welding position on the crossbeam 2, and at the same time suppress the deformation at the welding position on the column 1, thus protecting the welding position.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model 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 or all of the technical features therein.
