Description

Technical Field

[0001] The invention belongs to the technical field of in-vehicle equipment systems for rail vehicles and urban rail vehicles, and in particular relates to a hidden supporting wall type semi-enclosed berth structure for rail vehicles. Background Art

[0002] In previous sleeper EMUs, the beds are generally equipped with a flat bed structure, which requires support and load-bearing installation using a lifting bracket. Not only is the installation method complicated and the inspection and disassembly time-consuming, but the passengers' heads and bodies are in direct contact with the compartment partitions or the interior wall panels of the carriage, resulting in loud noise at the passenger's head position and the passenger's body feeling cold when it touches the partition walls. Summary of the invention

[0003] The purpose of the present invention is to use a semi-enclosed bed board to soundproof and reduce noise at the passenger's head position, while optimizing the supporting bracket structure, thereby reducing the temperature difference in the passenger's body contact parts and comprehensively improving the passenger's comfort, simplifying the installation method of the berth structure, and achieving the same structural strength effect.

[0004] To achieve the above-mentioned purpose, the present invention provides a hidden support wall type semi-enclosed berth for rail vehicles, comprising a mat, an upper mask, a berth frame, an armrest outer frame, an armrest frame, an installation angle code and a lower mask. The berth frame is an integrated welded structure, and the overall structure is a "ship" type structure. One side of the berth frame is open, and the other three sides are provided with vertical panels. The berth frame is provided with 6 connecting holes on the vertical panels close to the side of the compartment partition wall. The upper mask and the lower mask are respectively bonded to the upper surface and the lower surface of the berth frame. The upper mask and the lower mask are respectively provided with through holes corresponding to the connecting holes of the berth frame. The armrest frame is installed on the lower cross beam of the opening surface of the berth frame. The armrest outer frame is bonded to the armrest frame. The mat is bonded to the upper mask by 3M buckles. The compartment partition wall is provided with through holes corresponding to the connecting holes of the berth frame vertical panels. The berth structures on both sides of the compartment partition wall are fixed to the compartment partition wall by fasteners passing through the connecting holes of the berth frame.

[0005] Furthermore, the upper cover plate and the lower cover plate are respectively composed of an aluminum plate profile with a layer of cover cloth bonded to the outer surface.

[0006] Furthermore, the armrest frame is fixed on the lower cross beam of the open surface of the berth frame through three mounting angle brackets.

[0007] Furthermore, buckle covers are provided at the connection holes of the berth frame to ensure that the fasteners do not leak out.

[0008] Compared with the prior art, the present invention has the following positive effects:

[0009] 1. The sleeper frame can use the vertical panels and the bonded upper and lower panels to insulate and reduce noise at the passenger's head position and reduce the temperature difference at the passenger's body contact parts;

[0010] 2. The deck structure uses 6 connection holes on the vertical enclosure, and adopts a structure that penetrates the partition wall of the private room, and is connected to the opposite bed by M12 bolts. The strength of this structure is equivalent to that of the supporting bracket structure;

[0011] 3. Simplify the installation method of the berth structure and achieve the same structural strength effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Reference Figure 1 , Figure 2 The berth frame 3 is an integrated welded structure, and the overall structure is a "boat" shape with one side open, and the other three sides are provided with vertical panels 9. The vertical panels 9 on the side of the berth frame 3 close to the compartment partition wall 11 are provided with 6 connecting holes, and the upper cover plate 2 and the lower cover plate 7 are respectively bonded to the upper surface and the lower surface of the berth frame 3, and the upper cover plate 2 and the lower cover plate 7 are respectively provided with through holes corresponding to the connecting holes 12 of the berth frame 3. The armrest frame 3 is installed on the lower cross beam 10 of the opening surface of the berth frame 3, the armrest outer frame 4 is bonded to the armrest frame 5, and the mat 1 is bonded to the upper cover plate 2 by 3M buckles; buckle covers 8 are provided at the connecting holes 12 of the berth frame 3 to ensure that the fasteners do not leak out.

[0018] Reference Figure 3The upper cover plate 2 and the lower cover plate 7 are both composed of a layer of cloth bonded to the outer surface of an aluminum profile; the handrail frame 5 is fixed to the lower crossbeam of the open surface of the berth frame through three mounting angle brackets 6. The advantage of this mechanism is that it is easy to install, the bolt connection structure does not leak, and it is convenient for the later inspection and replacement of the damaged railings;

[0019] Reference Figure 4 The compartment partition wall 11 is provided with through holes corresponding to the connection holes 12 of the berth frame 3 , and the semi-enclosed berth structures on both sides of the compartment partition wall 11 are fixed to the compartment partition wall 11 through the connection holes 12 of the berth frame 3 by fasteners.

[0020] During installation, the armrest frame 5 is installed to the berth frame 3 using bolts through three installation angle codes 6, the armrest outer frame 4 is bonded to the armrest frame 5, and then the upper mask 2 structure is bonded to the upper plane of the berth frame 3, and the lower mask 7 is bonded to the lower plane of the berth frame 3. Then the mat 1 is installed. Before installation, adjust the gap around the mat 1. After the gap is required to be uniform, use 3M buckles to bond and fix the mat 1. After the semi-enclosed berth is screwed into the connecting hole 12 of the berth frame 3, install, adjust and tighten it. Finally, use the buckle cover 8 to cover the connecting hole 12 to ensure that the installation bolts do not leak out.

[0021] The present invention now adds an integrally formed semi-enclosed berth frame 3 and an upper cover 2 and a lower cover 7 bonded to the upper and lower surfaces of the berth frame 3 to the existing berth frame 3 structure, which prevents the passenger's head and body from directly contacting the compartment partition wall 11 or the interior wall panel of the carriage, and solves the problems of loud noise at the passenger's head position and the passenger feeling cold when the body touches the partition wall. At the same time, the original way of supporting the berth by the lifting bracket is changed, and the vertical panels 9 of the berth frame 3 and the compartment partition wall 11 are opened with connecting holes and through holes are opened in the semi-enclosed berth, and M12 bolts and nuts are used to fasten the semi-enclosed berth to the two sides of the compartment partition wall 11. Compared with the existing installation method, the installation structure is simplified and the time for inspection and replacement is reduced, and the improved installation method can achieve the same structural strength effect.
