[0041] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0042] Traditional sleeper compartment air ducts are typically located on the side walls, transverse walls, or above the berths, making them difficult to install. When ducts are located on transverse walls and side walls, they typically require air outlets. This arrangement results in the following consequences: 1. The transverse and side walls must be thickened to strengthen them and ensure the strength of the compartment's main structure; 2. The need to reserve space for the air ducts significantly increases the space occupied by the transverse and side walls, further compressing the interior of the carriage. To maintain the same passenger capacity, the berths and passenger mobility space must be reduced. Furthermore, traditional sleeper compartments only have one air outlet per berth, which can lead to poor ventilation.

[0043] The present invention arranges the sleeper air duct in the pillars of the sleeper compartment. On the one hand, this arrangement makes the installation of the air duct in the sleeper compartment more convenient, greatly improves the installation efficiency of the sleeper car, reduces the installation cost, and can reduce the space occupied by the air duct in the car, saving space for the car, and making the passengers' activity space and berth space larger; on the other hand, by arranging air ducts on the pillars at both ends of the sleeper compartment, each berth is provided with air outlets connected to the air duct at the head and foot, this arrangement improves the uniformity of air supply in the berth, solves the problem that passengers need air supply at the head and the tail of the berth, and passengers can choose to have air outlet at the head or the foot.

[0044] After introducing the basic principles of the present invention, various non-limiting embodiments of the present invention are described in detail below. The numbers of any elements in the drawings are for illustration only and not for limitation, and any names are for distinction only and do not have any limiting meaning.

[0045] The principles and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0046] Example 1:

[0047] like Figure 1 The sleeper compartment shown is arranged in a longitudinal distribution along the length of the sleeper car. The sleeper compartment 1 includes:

[0048] There are two transverse walls 13, which are arranged opposite to each other;

[0049] A longitudinal wall 14 is provided along the length direction of the sleeper compartment, and the longitudinal wall 14 separates the sleeper compartment 1 from the aisle;

[0050] There are two upright columns 15, each of which is located at the connecting corner of the transverse wall 13 and the longitudinal wall 14. The upright columns 15 are configured as a hollow structure; an connecting angle air duct 33 is provided in the hollow upright columns 15. The connecting angle air duct 33 extends along the height direction of the vehicle compartment, and the fresh air in the connecting angle air duct 33 is transmitted downward from the upper end of the connecting angle air duct 33;

[0051] The sleeping compartment 1 is set as a double-layer structure, which comprises an upper berth and a lower berth. The connecting angle air duct 33 is provided with an air outlet on each corresponding berth, and each berth is provided with two air outlets, which are respectively located at the head and the tail of the berth.

[0052] Of course, in other embodiments, the sleeper compartment 1 can also be configured as a three-layer structure, with three berths, namely, an upper berth, a middle berth and a lower berth.

[0053] The air outlet is a grille structure that can be rotated. An adjustment knob is provided on the air outlet to control the rotation of the grille structure, thereby controlling the direction and volume of air outflow from the air outlet and the opening and closing of the air outlet.

[0054] In order to balance the air output of the upper and lower bunks, the grille spacing of the upper bunk air outlet is smaller than that of the lower bunk air outlet.

[0055] In order to solve the problem of wiring arrangement and storage in the sleeper compartment 1, a junction box 153 is further provided inside the column 15 for wiring and storage of the wiring in the sleeper compartment 1.

[0056] To meet the individual lighting needs of different passengers, each berth is equipped with a light 16 with adjustable brightness and user-controllable on / off. Lights 16 are mounted on the outer wall of the pillars 15, and each berth is located above the air outlet. The wiring for the lights 16 is housed in a junction box 153.

[0057] Each berth is equipped with a sliding lumbar support 101, which can be adjusted up and down, forward and backward, allowing passengers to adjust the lumbar support according to their needs. The sliding lumbar support 101 is installed on the horizontal wall of the sleeper compartment 1, in the direction of the head of the berth (i.e., the direction of the passenger's head when resting).

[0058] The berth is also equipped with a storage basket 103 and a clothes hanger 104. The storage basket 103 allows passengers to store personal belongings and reduce clutter in the berth, while the clothes hanger 104 allows passengers to hang their clothes. In this embodiment, the storage basket 103 and clothes hanger 104 are located on another horizontal wall of the sleeper compartment 1 (i.e., toward the rear of the berth). In other embodiments, the storage basket 103 and clothes hanger 104 may also be located elsewhere within the berth, such as on a side wall within the berth space.

[0059] The clothes hanger 104 is hinged to the horizontal wall. When in use, the clothes hanger 104 is fixed at a certain angle to the horizontal wall so that the clothes on the clothes hanger 104 do not touch the horizontal wall. When the clothes hanger 104 is not in use, the clothes hanger 104 is folded, that is, the clothes hanger 104 is set parallel to the horizontal wall.

[0060] The storage basket 103 includes a rigid frame and a net bag, and the rigid frame is hinged to the horizontal wall; when the storage basket 103 is not in use, the rigid frame is folded and close to the horizontal wall; when the storage basket 103 is in use, the rigid frame is pulled outward, and at this time, the rigid frame and the horizontal wall are fixed at a certain angle, such as 30°, 45°, 60°, 90°, 120°, 135° or other arbitrary angles, and items can be placed in the net bag.

[0061] The berth is equipped with a small flip table 102, which is convenient for passengers to work or eat without taking up space. In this embodiment, the flip table 102 is mounted on a side wall within the berth space. To facilitate quick and easy assembly, the flip table 102 is mounted on a transverse wall of the sleeper compartment 1 (i.e., on the side of the sleeper compartment 1 that is not the side wall of the carriage). The flip table 102 is also equipped with an extension plate 1021 to increase the usable surface area of ​​the tabletop. The extension plate 1021 is rotatable relative to the tabletop. In this embodiment, the extension plate 1021 is hingedly connected to the tabletop of the flip table 102, allowing it to rotate about the hinge. During use, the extension plate 1021 rotates 180° about the hinge, from being flush with the tabletop of the flip table 102 to being flush with the tabletop. In other embodiments, the extension plate 1021 slides relative to the tabletop of the flip table 102 via grooves and rails, allowing the extension plate 1021 to be extended and retracted.

[0062] The above arrangement greatly improves the comfort of the passengers on the bed and maximizes the use of the activity space in the sleeper compartment 1.

[0063] Example 2:

[0064] The main difference between it and Example 1 is:

[0065] like Figure 2 and 3As shown, in order to increase the rigidity and strength of the columns 15, the columns 15 are arranged in a triangular prism-like shape. The triangular prism-like columns 15 are arranged at the side end connection of the inner side of the sleeping compartment 1 with a smooth arc transition. This design is both beautiful and easy to clean. The columns 15 include edge columns 151 and middle columns 152. The columns 15 that are not shared with other sleeping compartments 1 are edge columns 151, and the columns 15 shared by more than two sleeping compartments 1 are middle columns 152. Since the sleeping compartments 1 are of equal width and the transverse walls 13 and the longitudinal walls 14 of the sleeping compartments 1 are arranged perpendicular to each other, in this embodiment, the cross section of the edge columns 151 is arranged in a right-angled triangle-like shape. Since the right angles are too sharp and easily scratched, the right angles are rounded. To increase the strength of the edge columns 151, a reinforced corner 154 is added to the outside of the rounded corners. The top corners of the reinforced corners 154 are rounded, with the inner corners of the reinforced corners 154 being larger and the top corners being smaller. The cross-section of the middle column 152 is shaped like an isosceles triangle. The connecting angle duct 33 provided within the edge columns 151 is a one-way duct with outlets located only on the inner side of the sleeper compartment 1. The outlets correspond to the individual berths within the compartment, supplying fresh air to the berths. The connecting angle duct 33 provided within the middle column 152 is a multi-directional duct. A multi-directional duct is a three-way duct, with outlets located on the three sides of the middle column 152, hence the name "three-way duct." Of course, in other embodiments, the multi-directional air duct can also be a two-directional air duct, with air outlets only provided in the directions of the two sides of the middle column 152, and the air outlets are provided in the directions of the berths of two adjacent sleeping compartments 1 respectively.

[0066] Obviously, based on the above-mentioned embodiment 1 and embodiment 2, this embodiment also relates to a sleeper car, such as Figure 4-7 As shown, the sleeper car includes the above-mentioned sleeper compartment 1, as well as the activity area 2 and the air duct: the activity area 2 includes the partition space of the sleeper compartment 1, for passengers to move around and relax inside the car and outside the berth, and the air duct is used to provide fresh air to the sleeper compartment 1 and the entire sleeper car.

[0067] The sleeper compartments 1 are arranged in a longitudinal distribution along the length direction of the sleeper compartment. There are two types of sleeper compartments 1: a first compartment 11 and a second compartment 12.

[0068] The first compartments 11 are closely arranged from one end to the other of the sleeper compartment against the side wall of the sleeper compartment, forming two rows of compartments on both sides of the sleeper compartment, namely, the compartments in row A and the compartments in row B. The compartments in row A and row B are arranged symmetrically. In order to improve the daylighting in the berths in row A and row B, and to enable both upper and lower berth passengers to enjoy the scenery outside the window, thereby improving the passenger comfort, the side wall of the sleeper compartment is provided with upper and lower rows of windows 4 (such as Figure 8 and9 As shown in FIG, the upper and lower berths of the compartments in rows A and B are arranged so that each berth has a window 4. A stretchable blackout curtain is provided inside the window 4. Of course, in other embodiments, the compartments in rows A and B can also be arranged asymmetrically.

[0069] The second compartments 12 are longitudinally spaced apart in the compartments of column A or column B, near the aisle of the sleeper car. In this embodiment, the second compartments 12 are spaced apart in the middle of two adjacent first compartments 11 in column A (i.e., close to the wall 14 of the first compartments 11), and the second compartments 12 are staggered with the first compartments 11. Second compartments 12 are only provided in one row within the sleeper car (i.e., the compartments in column C), resulting in an asymmetrical arrangement of the sleeper compartments 1 within the sleeper car. An aisle is provided between the compartments in column C and column B for passengers to walk. By arranging the berths asymmetrically, the length and width of the berths are increased while ensuring that the capacity of each train remains unchanged. Furthermore, the sleeper compartments 1 are arranged in equal widths (i.e., the head and foot spaces of the berths are equal in width), improving passenger comfort while resting in the berths. In the berths of the second private room 12, in addition to the air outlets provided on the edge pillars 151 at the head and tail of the berth, there are also air outlets provided in the middle of the berth and on the middle pillar 152 of the first private room 11. That is, each berth in the second private room 12 is provided with three air outlets, which are located at the head, tail and middle of the berth respectively.

[0070] Sleeper compartments 1 are equipped with ladders 17 for passengers climbing to the upper berth. In this embodiment, the ladders 17 for the compartments in row A are mounted on the outer wall 13 of the transverse wall 13 of the compartments in row C, while the ladders 17 for the compartments in rows B and C are mounted on the longitudinal wall 14 of the corresponding compartments. For passenger safety, handrails 18 are installed at the top of the ladders 17 for passengers to hold onto when climbing.

[0071] like Figure 4 The activity area 2 shown is composed of the space between two adjacent second compartments 12, plus the space extending to the first compartment 11 opposite the aisle of the sleeper car. Each sleeper car has four activity areas 2 for passengers. The activity area 2 is equipped with a flip bench 21 and a flip table 22, which can serve as a rest area for passengers. This improves passenger comfort and space outside of their berths, solving the problem of insufficient space for passengers to move around outside of their berths. A luggage rack 23 is located above the activity area 2, which not only improves the utilization of the car space, but also allows passengers to place their luggage near their berths, eliminating the need to place it at the car entrance, thus solving the problem of passengers worrying about their luggage being taken by mistake.

[0072] In this embodiment, the flip bench 21 and the flip table 22 are arranged on the outer wall of the longitudinal wall 14 of the B column private room, and the flip bench 21 and the flip table 22 are connected to the outer wall of the longitudinal wall 14 through hinges.

[0073] A luggage rack 23 is mounted on the outer wall of the middle column 152. The height of the rack is just right for passengers to place their luggage while standing. A guardrail 231 is provided on the rack to prevent luggage from falling. A flip bench 21 or flip table 22 can be located below the rack. The flip bench 21 provides a rest area for passengers, while the flip table 22 provides a place for passengers to store small items.

[0074] The air duct includes a main duct 31, branch ducts 32, connecting angle ducts 33, and an exhaust vent. The main duct 31 is located at the top of the vehicle compartment and is used to guide fresh air into the vehicle compartment. The main duct 31 runs through both ends of the vehicle compartment in the longitudinal direction. Branch ducts 32 are located on both sides of the main duct 31 and communicate with the main duct 31. The branch ducts 32 are used to connect with the connecting angle duct 33. The branch ducts 32 and the connecting angle duct 33 are sealed by flanges. The exhaust vent is located at the bottom of the vehicle compartment and is used to exhaust polluted air from the vehicle compartment.

[0075] Fresh air in the main air duct 31 flows through two branch air ducts 32 to the connecting angle ducts 33 of the sleeper compartment 1, where it flows downward along these ducts. One branch of fresh air flows through the connecting angle duct 33 at the head of the sleeper compartment 1 and, after adjustment by a knob located at the head air outlet of the berth, flows into the space corresponding to the berth. The other branch of fresh air flows through the connecting angle duct 33 at the tail of the sleeper compartment 1 and, after adjustment by a knob located at the tail (or foot) air outlet of the berth, flows into the space corresponding to the berth. Compared to the prior art, the fresh air in the main air duct 31 flows through the connecting angle ducts 33 at the head and tail of the sleeper compartment 1, respectively, to the head and tail of the berth in the opposite sleeper compartment 1. Furthermore, the amount of fresh air flowing to the upper and lower berths is adjustable.

[0076] This embodiment also relates to a rail vehicle, which includes the above-mentioned sleeper car.
