Technical Field

[0001] The invention relates to a high-speed rail vehicle such as an EMU, and in particular to a rail vehicle window structure, belonging to the technical field of rail vehicle interior equipment. Background Art

[0002] With the rapid development of high-speed rail vehicles, the requirements for the equipment installed in the carriages are getting higher and higher, in order to improve the grade of the carriages and meet the personalized needs of high-end passengers. Since high-speed trains run at a high speed and passengers do not take a long time on high-speed trains, seats are generally equipped in the carriages of high-speed trains, and berths are equipped in the carriages of some long-distance rail vehicles.

[0003] Existing rail vehicles generally have windows on the side walls of the vehicle body. The height of the windows is significantly smaller than the width of the windows. Since the windows and seats are set independently, the front and rear rows of seats correspond to the same window, or some seats can only correspond to the side walls. This will affect the riding comfort of passengers. Passengers can observe the activities of passengers in another adjacent row of seats through the windows, which cannot meet the passengers' higher requirements for privacy. Summary of the invention

[0004] The main purpose of the present invention is to solve the above-mentioned problems and shortcomings and to provide a rail vehicle compartment that can increase the window field of view, improve the visual effect, and enhance the riding comfort.

[0005] Another main object of the present invention is to provide a rail vehicle having the above rail vehicle window structure.

[0006] To achieve the above object, the technical solution of the present invention is:

[0007] A rail vehicle window structure, wherein the window extends continuously upward from the position of the side wall to the position of the roof plate.

[0008] Furthermore, the upper portion of the vehicle window has a curved shape, which is the same shape as the vehicle body.

[0009] Furthermore, the vehicle window is composed of a window frame and a transparent material, the transparent material is bonded and fixed to the window frame, and the window frame is installed on the vehicle body frame through fasteners.

[0010] Furthermore, the transparent material is a hollow double-layer glass structure.

[0011] Furthermore, the transparent material is a continuous integrated structure at the side walls and side roofs of the vehicle body.

[0012] Another technical solution of the present invention is:

[0013] A rail vehicle has the rail vehicle window structure as described above installed on its vehicle body.

[0014] Furthermore, two rows of seat units are arranged in the compartment along the length direction of the vehicle body, and a window is opened on the side wall of the vehicle body corresponding to each seat unit.

[0015] Furthermore, the seat unit includes a partition wall that encloses the seat unit, and a seat, a footrest, a table and a functional chair are installed in the partition wall. The footrest is installed directly in front of the seat, the table is installed on the side of the seat facing the side wall, the window is opened between the table and the partition wall of the front seat unit, and the functional chair is installed below the window.

[0016] Furthermore, the seat is tilted toward the vehicle window on this side.

[0017] Furthermore, the carriage includes a plurality of private rooms separated by partitions, each of the private rooms has a rest area and a toilet, and a window is opened on the vehicle body corresponding to the rest area and the toilet respectively.

[0018] In summary, the rail vehicle window structure and rail vehicle described in the present invention have the following advantages compared with the prior art:

[0019] (1) In the present invention, the window is continuously extended from the side wall to the side top, which greatly increases the window field of view, improves the visual effect, and provides passengers with the best sight and user experience. Moreover, passengers sitting in the seat tilted toward the window can enjoy a more perfect view outside the vehicle through the window extending from the side wall to the side top, and can also reduce the passenger's motion sickness to a certain extent.

[0020] (2) In the present invention, each seat unit corresponds to a group of windows, and the windows corresponding to the seat units are independent of each other. The activities of passengers in the seat units will not be reflected by the window glass onto the windows of another adjacent seat unit, thereby further improving the privacy of each seat unit and also improving the riding comfort of passengers.

[0021] (3) In the present invention, windows are respectively arranged in the rest area and the toilet of the business compartment, so that passengers can enjoy the scenery outside the car through the car windows whether in the rest area or when using the toilet, thereby improving the riding comfort.

DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0031] Embodiment 1:

[0032] like Figure 1 As shown, a rail vehicle provided by the present invention is composed of a head car at both ends and a plurality of intermediate cars 1 in the middle.

[0033] like Figure 1 As shown, each middle carriage 1 is also divided into two layers, the upper layer is a passenger compartment 1a for passengers, and the lower layer is a cargo compartment 1b for placing goods. The upper passenger compartment 1a and the lower cargo compartment 1b are separated by a passenger compartment floor 2. The upper passenger compartment 1a includes business compartments, first-class compartments, and second-class compartments.

[0034] The upper passenger compartment 1a and the lower cargo compartment 1b correspond to two platforms respectively. Passengers and cargo get on and off the train at different platforms, realizing the separation of people and cargo without affecting each other. This can not only greatly shorten the time required to stop at each station, but also ensure the safety of passengers getting on and off the train, which is particularly suitable for long-distance operations. In order to facilitate the identification and loading and unloading of goods, the goods are placed in small containers, and the identification and loading and unloading of containers are automatically completed by robots.

[0035] The cargo compartment 1b on the lower level is a through structure, with a partition or other structure used to separate the equipment compartment and the cargo compartment. The equipment compartment is located above the bogie, and the cargo compartment is located between the two bogies. A supporting structure 3 is arranged at regular intervals in the cargo compartment. The supporting structure 3 preferably adopts a metal frame structure to ensure the overall structural strength of the supporting structure 3. The supporting structure 3 is arranged along the width direction of the vehicle body. In addition to supporting the passenger compartment 1a on the upper level, the cargo compartment can also be divided into multiple different functional areas to facilitate the separation and placement of different types of goods, and to facilitate the identification and loading and unloading of goods.

[0036] A skirt is installed on both sides of the equipment compartment of the cargo compartment 1b in the width direction of the vehicle body, and a folding door (not shown in the figure) is installed on both sides of the cargo compartment in the width direction of the vehicle body. Ball bearings and other structures are arranged on the floor of the cargo compartment to facilitate the movement of containers on the floor. A container positioning structure is also arranged on the floor. After the container is installed in the specified position, the positioning structure fixes the container to ensure that the container can be stably fixed during the long-distance transportation of the vehicle. When the goods need to be loaded and unloaded at the station, the folding door is opened upwards, and the robot automatically identifies the container that needs to be unloaded and pushes it out of the cargo compartment 1b into the unloading area of ​​the platform. At the same time, the robot pushes the new container that needs to be loaded on the vehicle from the loading area of ​​the platform into the cargo compartment 1b according to the set position.

[0037] like Figure 2 As shown, a door 4 for passengers to get on and off the train is provided at one or both ends of each intermediate carriage 1, and a retractable passage 6 is provided between the waiting area 5 on the platform and the door 4. Passengers can directly get on and off the train through the dedicated passage 6, and the existing train platform is no longer needed. Passengers no longer need to enter the platform from the waiting area 5 and then get on the train from the platform, which shortens the time for passengers to get on and off the train, improves the safety of getting on and off the train, and also improves the comfort of passengers when getting on and off the train, meeting the more humane needs of passengers. The passage 6 adopts a retractable structure, which is extended when the vehicle enters the station, so that its end is closely attached to the door 4, connecting the waiting area 5 with the door 4, and can be retracted after the passengers get on and off the train, without affecting other functions of the platform.

[0038] like Figure 2As shown, there is a platform 8 between two adjacent middle carriages 1, which is a transition area for passengers to temporarily stay after getting on or before getting off the train through the doors 4. In this embodiment, the platform 8 is designed as a whole in a circular shape, which can increase the number of people that can be accommodated by the platform 8, relatively expand the space for people to pass through, and effectively improve the congestion when there are many people getting on and off the train. Two doors 4 for getting on and off the train are symmetrically arranged on the circular platform 8 in the width direction of the car body, and two car end doors 9 for entering and exiting the middle car 1 are symmetrically arranged in the length direction of the car body. A wash basin 7 is installed on one side of the platform 8, omitting the independent washroom on the existing train, making full use of the space of the circular platform 8, and a shelf for placing towels and other items is installed above the wash basin 7 for the convenience of passengers. A toilet 10 is arranged on the other side of the platform 8, and a leisure sofa 11, a coffee table, etc. are also arranged on the platform 8 as a temporary leisure area for passengers. The structure of the entire platform 8 is very compact, and the functional areas in the platform 8 are reasonably arranged, which greatly improves the utilization rate of space, facilitates passengers to use, and provides more functions for passengers. Light strips, number lights and handrails are set on at least one side of the partition wall at the entrance of the door 4 to provide passengers with better services.

[0039] like Figure 2 The carriage shown is a first-class carriage in the passenger area carriage 1a on the upper level, and the carriage includes two rows of seat units 12 arranged along the length direction of the car body, and a carriage aisle 13 is formed between the two rows of seat units 12. The front and rear seat units 12 are staggered and overlapped in the length direction of the car body to reduce the space occupied by each seat unit. Under the premise of ensuring the comfort of the passengers, the number of occupants in the carriage is greatly increased, thereby maximizing the utilization rate of the carriage space.

[0040] like Figure 3 As shown, each seat unit 12 is separated by a partition 14, and the partition 14 is a half-height partition, which can ensure the comfort of sitting and make each seat unit 12 have excellent privacy. The material of the partition 14 is composed of an outer layer of composite wood, a middle layer of sponge and an inner layer of linen. The outermost layer of the composite wood (i.e., the outer surface of the partition 14) has a decorative board, such as a decorative board with a wood grain surface. The decorative board can also be a glass board, which can ensure the overall structural strength of the partition 14 and improve the overall aesthetics of the partition 14.

[0041] The partition 14 is an L-shaped structure consisting of a transverse partition 14a and a longitudinal partition 14b, wherein the transverse partition 14a is S-shaped, the inner side of the transverse partition 14a (i.e., the side adjacent to the side wall 19) is recessed toward the interior of the seat unit 12, and the outer side of the transverse partition 14a (i.e., the side adjacent to the compartment aisle 13) is recessed toward the exterior of the seat unit 12. The transverse partition 14a and the longitudinal partition 14b are fixedly connected by a connecting piece, the bottoms of the transverse partition 14a and the longitudinal partition 14b are fixedly connected to the compartment floor, and one side of the transverse partition 14a is fixedly connected to the side wall 19.

[0042] Each seat unit 12 includes a seat 15, a footrest 16, a table 17 and a functional chair 18. Each seat 15 is tilted toward the side wall 19 on that side, that is, tilted toward the direction of movement of the vehicle, and preferably tilted at an angle of 45 degrees. The seat 15 extends in the outwardly concave space on the outer side of the transverse partition 14a of the seat unit 12 and the inwardly concave space on the inner side of the transverse partition 14a of the front seat unit 12, so as to save the space occupied by each seat unit 12 to the maximum extent and improve the utilization rate of the space in the vehicle compartment.

[0043] The seat 15 is composed of a backrest 20, a seat cushion 21 and a movement mechanism. The backrest 20 and the seat cushion 21 are both composed of a frame, a sponge pad and an outermost decorative cloth. The backrest 20 and the seat cushion 21 are hinged, and the movement mechanism is arranged below the seat cushion 21. The movement mechanism drives the backrest 20 and the seat cushion 21 to move. When switching from a sitting position to a lying position, the movement mechanism drives the seat cushion 21 to move forward, and the backrest 20 moves downward therewith until the seat cushion 21 and the backrest 20 are on the same horizontal plane. When switching from a lying position to a sitting position, the movement direction is exactly opposite. The seat cushion 21 can stop at any intermediate position, that is, the backrest 20 can stop at any reclining angle. The passenger can realize the conversion of the seat 15 between a sitting position, a lying position and any reclining position by operating the switch, so as to meet the different needs of the passengers.

[0044] The footrest 16 is fixed below the inner side of the transverse partition 14a of the front seat unit 12, and the frame of the footrest 16 is fixed to the transverse partition 14a by bolts. When the seat 15 is in a lying position, the seat cushion 21 will extend forward to the footrest 16, and the footrest 16, the seat cushion 21 and the backrest 20 together form a horizontal berth, which can not only save space, but also ensure that the passengers are more comfortable when resting on the berth.

[0045] A storage platform 22 is provided in the space between the side of the seat 15 close to the aisle 13 and the longitudinal partition wall 14b. The storage platform 22 is flush with the seat cushion 21. On the one hand, it fills the gap between the seat cushion 21 and the longitudinal partition wall 14b, and on the other hand, it is convenient for passengers to use.

[0046] A table 17 is arranged between the other side of the seat 15 and the side wall 19. The table 17 is formed by the plane formed by the lower half of the transverse partition 14a being recessed forward. The side of the table 17 is close to the side wall 19. The table 17 and the transverse partition 14a are an integrated structure, which not only makes the structure of the seat unit 12 simpler, but also facilitates the modular assembly of the seat unit 12, and also ensures the overall aesthetics of the transverse partition 14a. The table 17 is provided with cup holders and other components for passengers to use, and books, magazines and other items can also be placed on the table 17. A wall lamp 23 is also installed on the transverse partition 14a above the table 17, which can be controlled by passengers as needed, for the convenience of passengers. The footrest 16 in the rear seat unit 12 is installed in the space recessed forward by the transverse partition 14a, that is, installed below the table 17 of the front seat unit 12, so as to make full use of the recessed space below the table 17, and there is also space below the footrest 16 for passengers to place shoes and other items.

[0047] A movable, independently installed functional chair 18 is also provided in front of the table 17. The functional chair 18 is located below the windowsill of the car window 24. The functional chair 18 is directly placed on the floor of the car. Passengers can move the functional chair 18 to the desired position and angle as needed for convenient use. The functional chair 18 can be used for passengers who temporarily come to the seat unit 12 to sit on it, so as to chat with the passengers in the seat unit 12.

[0048] In order to improve the riding comfort, a TV set 25 is also installed in each seat unit 12. The TV set 25 is installed on the transverse partition wall 14a of the front seat unit 12, specifically, it is installed above the transverse partition wall 14a, that is, the wall surface that is not recessed forward. The TV set 25 can be a flat-screen TV or a curved TV, and the TV set 25 can also be embedded in the transverse partition wall 14a.

[0049] A partition door 26 is provided between the longitudinal partition walls 14b of the front and rear seat units 12 to close the gap between the two adjacent seat units 12, so as to further improve the privacy of each seat unit 12. In this embodiment, the door door 26 is a sliding door, and the longitudinal partition wall 14b is a hollow structure. The partition door 26 is hidden in the longitudinal partition wall 14b when in an open state, and is integrated with the longitudinal partition wall 14b to save the space occupied by the partition door 26. The partition door 26 extends from the inside of the longitudinal partition wall 14b when in a closed state.

[0050] Decorative lights and number lights (not shown) are arranged on the outer surface of each longitudinal partition 14b, and decorative lights and number lights can also be arranged on the outer surface of the partition door 15. The number lights help passengers find their seat units 1 as quickly as possible. Arranging multiple decorative lights on the partitions 14 on both sides of the carriage aisle 2 can not only play a lighting role, but also increase the overall aesthetics of the carriage interior.

[0051] The decorative lights can be light strips composed of multiple parallel light strips, and the light strips can be horizontal light strips, vertical light strips, oblique light strips, arc light strips, etc. The decorative lights can also be special figures or patterns composed of multiple light strips. In this embodiment, it is preferred to set multiple parallel and oblique light strips on the outer surface of the longitudinal partition 14b, and the multiple light strips form an oblique light strip, which is simple, beautiful and generous.

[0052] like Figure 4 As shown, a rail vehicle window structure is provided in this embodiment, and a window 24 is opened on the side wall 19 of the vehicle body. The window 24 extends continuously upward from the position of the side wall to the position of the roof panel, including part of the side wall and part of the side top (referring to the position where the side wall 15 of the vehicle body is connected and transitioned to the roof panel). The window 24 is opened between the table 17 and the transverse partition 14a of the front seat unit 12, and the overall shape is slender and has an arc surface on the upper part, which is the same as the shape of the side wall and the side top of the vehicle body.

[0053] like Figure 4 As shown, the vehicle window 24 is composed of a window frame 27 and a transparent material 28. The transparent material 28 is a hollow double-layer glass structure. The transparent material 28 is bonded and fixed to the window frame 27. An opening is opened at the side wall and the side top of the vehicle body. The two sides of the window frame 27 match the shape of the vehicle body. The window frame 27 is installed on the vehicle body frame 29 at the opening through fasteners. The transparent material 28 adopts a hollow double-layer glass structure, and the transparent material 28 is a continuous integrated structure at the side wall and the side top of the vehicle body.

[0054] like Figure 2 As shown, in the present embodiment, a window 24 is provided on the vehicle side wall 19 corresponding to each seat unit 12, and the windows of each seat unit 12 are independent of each other. The activities of passengers in the seat unit 12 will not be reflected on the window 24 of another adjacent seat unit 12 through the reflection of the window glass, thereby further improving the privacy of each seat unit 12.

[0055] The window 24 of this structure increases the window area and the overall height of each seat unit 12, thereby greatly increasing the window field of view, improving the visual effect, and providing passengers with the best sight and user experience. Passengers sitting on the seat 15 tilted toward the window 24 can enjoy a more perfect view outside the vehicle through the window 24 extending from the side wall 19 of the vehicle body to the side top, and can also reduce the passenger's motion sickness to a certain extent.

[0056] Embodiment 2:

[0057] like Figure 5 and Figure 6 As shown, the carriage in this embodiment is a business carriage, including a plurality of private rooms 30, which are arranged on one side of the carriage along the length direction of the carriage body, and between the private rooms 30 and the side wall 19 of the carriage body on the other side is the carriage aisle 13. The private rooms 30 are divided by partitions 31, and the partitions 31 are fully enclosed structures from the carriage floor to the carriage roof, and a private room door 32 for entering and exiting the private room is arranged on the partition 31 of each private room 30.

There is an area for passengers to move between the double sofa 35 and the two sofa stools 36, making full use of the limited space of the rest area 33. At night, the seat cushion of the double sofa 35 moves forward under the drive of the transmission mechanism, and the backrest moves downward to a horizontal state, and the positions of the two sofa stools 36 are moved, so that the double sofa 35 and the two sofa stools 36 are combined into a horizontal bed for passengers to rest at night. Each private room 30 can be used by two adults and one or two children, which can fully meet the needs of a family. According to the space of the rest area 33, only one set of double sofas 35 may be provided, and the double sofas 35 become a sofa bed when laid flat.

[0062] The toilet 34 is separated by a partition 37, and a toilet door is installed on the partition 37. The partition 37 is extended from one side of the compartment door 32 to the opposite side wall. The partition 37 is designed in an arc shape as a whole, which reasonably divides the space of the toilet 34 and the rest area 33, and also provides an arc-shaped passage for passengers entering the compartment 30 from the compartment door 32 to enter the rest area 33. A washbasin 38, a toilet 39 and a bathtub 40 are arranged in the toilet 34 to meet the different use requirements of passengers. The bathtub 40 is arranged horizontally close to the side wall 19 of the vehicle body, and the washbasin 38 is installed near the partition 31 on the side of the compartment 30. The washbasin 38 is installed between the bathtub 40 and the toilet 39, and the toilet 39 is installed between the partition 37 at the entrance of the compartment door 32 and the partition 31 on the side. The entire toilet 34 has a reasonable and compact space layout, which can achieve 100% space utilization.

[0063] Decorative lights and room number lights are installed on the outer surface of the partition wall 31 of the compartment 30. The decorative lights and room number lights can also be installed on the compartment door 32. The room number lights are convenient for passengers to confirm whether the number of the compartment 30 is correct after getting on the bus. The decorative lights can not only play the role of lighting, but also play the role of decoration, thereby improving the overall aesthetic effect of the carriage. The decorative lights can be light strips composed of multiple parallel light strips. The light strips can be horizontal light strips, vertical light strips, inclined light strips, arc light strips, etc. The decorative lights can also be special graphics or patterns composed of multiple light strips. The decorative lights can not only play the role of lighting, but also play the role of decoration, thereby improving the overall aesthetic effect of the carriage aisle 13.

[0064] like Figure 5 and Figure 6As shown, each compartment 30 is provided with a window on the side wall 19 of the vehicle body, and two windows are installed in each compartment 30. A first window 41 is provided on the side wall 19 of the vehicle body corresponding to the rest area 33, and a second window 42 is provided on the side wall 19 of the vehicle body corresponding to the toilet 34. The second window 42 is provided above the bathtub 40. Whether in the rest area 33 or in the toilet 34, the passenger can view the scenery outside the window through the first window 41 and the second window 42, thereby improving the riding comfort. In order to ensure the privacy requirements of the passengers, the first window 41 and the second window 42 are both coated glass, so that the people outside the window cannot see the activities of the passengers inside the window, and the passengers' viewing of the scenery outside the vehicle is not affected.

[0065] In this embodiment, the first window 41 and the second window 42 extend continuously upward from the side wall 19 of the vehicle body to the position of the roof of the vehicle body, including part of the side wall and the side roof (referring to the position where the side wall 19 of the vehicle body is connected and transitioned to the roof panel). The upper part of the first window 41 and the second window 42 has an arc shape, which is the same as the shape of the side wall and the side roof of the vehicle body. The area of ​​the first window 41 is relatively large, and its width is equivalent to the width of the rest area 33 at the side wall 19 of the vehicle body. The area of ​​the second window 42 is relatively small and is in the shape of a long and thin strip as a whole. The structure of the first window 41 and the second window 42 increases the window area and the overall height of each private room while ensuring the strength and rigidity of the overall side wall 19 of the vehicle body. It can not only ensure the lighting effect of the private room 30, but also greatly increase the window field of view, improve the visual effect, and provide passengers with the best line of sight and user experience.

[0066] The structures of the first window 41 and the second window 42 are the same as those described in the first embodiment and will not be described in detail here.
