Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, and in particular to a business class cabin for rail vehicles. Background Technology

[0002] With the rapid development of rail transit technology, the business class of rail vehicles (also known as the conference area or sightseeing area of ​​rail vehicles) is becoming increasingly popular as a new form of tourism.

[0003] However, existing rail vehicle carriages have fixed seating layouts and limited functions, failing to meet the diverse needs of passengers, such as:

[0004] Each seat requires manual foot pedal adjustment to change direction, making it impossible to achieve intelligent operation;

[0005] Passengers cannot adjust the seat orientation according to personal preferences or sightseeing / meeting needs, resulting in poor flexibility.

[0006] Televisions are usually located on the inner walls at both ends of the carriage, and the broadcast is controlled uniformly by the vehicle. Although the televisions in some vehicles can be adjusted up and down, the height of the televisions can never meet the needs of all passengers in the carriage at the same time. They are either too high or too low, which is not comfortable enough.

[0007] The tables in the carriage are either fixed behind the seats, which makes it inconvenient for passengers in the back to get in and out; or they are provided as separate, fixed tables in front of the seats, which take up a lot of space in the carriage and cannot be adjusted forward or backward after the vehicle changes direction.

[0008] When passengers adjust their sitting posture, such as half-lying down, while the rail vehicle is in motion, they have nowhere to put their feet, and it is very uncomfortable to put them on the ground.

[0009] Currently, business class does not have meeting or conference functions, which cannot meet the needs of passengers for meeting or conference in scenarios such as business travel and family trips.

[0010] The above-mentioned issues cannot meet the increasingly higher demands of passengers for their travel experience, especially for the business class of rail vehicles. There is an urgent need to develop a product that can solve all of these problems. Utility Model Content

[0011] In order to solve the above-mentioned problems of the prior art, the present invention provides a business class cabin for rail vehicles with a high level of passenger experience.

[0069] like Figures 1 to 17As shown, a business class 1 for rail vehicles according to a specific embodiment of the present invention includes a side cabinet 300, a triangular cabinet group, and multiple rotatable seats 700. The side cabinet 300 is installed on the inner side wall 10 of the business class 1, and a triangular cabinet group drive device 500 is installed inside it. The triangular cabinet group is movably installed on each side cabinet 300 and has a pair of spaced-apart triangular cabinets 100. Each triangular cabinet 100 includes a work surface 101, a support base 103, an internal foot cavity 109, a liftable TV 102 located on the front and rear sides of the triangular cabinet 100, and a TV lifting drive device 104 for driving the corresponding liftable TV 102. One of the multiple rotatable seats 700 is arranged on the front and rear sides of each triangular cabinet 100. A centralized control system 900 is electrically connected (i.e., circuit connected) to the triangular cabinet group drive device 500, the TV lifting drive device 104 and the rotatable seats 700, so that the front and rear positions of the triangular cabinet group can be adjusted according to the direction of travel of the rail vehicle, and the usage status of the liftable TV 102 and the rotatable seats 700 can be adjusted according to the needs of business class passengers.

[0070] It should be noted that in this embodiment, the side cabinet 300 and the triangular cabinet group constitute a multi-functional cabinet; it should be understood that in this embodiment, the business class 1 for rail vehicles also has a lighting system, which is also controlled by the centralized control system 900. It should also be noted that, although... Figure 1 Each cabin interior wall 10 of the business class 1 shown has only one triangular cabinet set. The entire business class 1 has six rotatable seats 700. However, the number of triangular cabinet sets on each cabin interior wall 10 and the number of rotatable seats 700 in the entire business class 1 can be changed as needed, as long as there is one rotatable seat 700 on each side of each triangular cabinet 100.

[0071] It should be noted that, in this embodiment, the triangular cabinet group drive device 500 is configured to drive the triangular cabinet group to switch between forward and backward positions under the control of the centralized control system 900, according to the travel direction of the rail vehicle (see respective...). Figure 1 and Figure 18 The TV lift drive device 104 is configured to drive the liftable TV 102 to switch between a stowed position and a raised position under the control of the centralized control system 900, according to passenger needs (see reference). Figure 11The two liftable TVs 102 on the front and rear sides of the triangular cabinet are positioned such that one is in the storage position and the other is in the raised position. When the liftable TV 102 is in the raised position, the built-in foot cavity 109 is fully exposed. The rotatable seat 700 has a seat rotation system, which is configured to drive the rotatable seat to rotate around its own axis within a range of 0-315º under the control of the centralized control system according to the direction of travel of the rail vehicle and / or passenger needs, so as to adjust the facing direction of the rotatable seat 700.

[0072] Additionally, it should be noted that in this embodiment, the centralized control system 900 of the business class 1 includes a centralized control screen (not shown) and various control modules (not shown) for receiving instructions from the centralized control screen to control the triangular cabinet group drive device 500, the TV lifting drive device 104, and the seat rotation system of the rotatable seat 700, thereby driving the movement of the triangular cabinet group to realize seat reversal, driving the lifting TV 102 to meet the viewing / resting needs in different scenarios, and driving the rotation of the rotatable seat 700 to realize 2-person meeting, 4-person meeting, and 6-person conference modes.

[0073] like Figures 3 to 9 As shown, and with reference Figures 10 to 17 In this embodiment, the triangular cabinet assembly includes a pair of triangular cabinets 100 connected together and slidably mounted on the side cabinet 300. Each triangular cabinet 100 includes a work surface 101, a support base 103, a built-in foot cavity 109, and a storage position located on the front and rear sides of the triangular cabinet 100 (see...). Figure 11 The state shown by the retractable TV on the right side of the middle section) and the raised position (see Figure 11 The liftable TV 102 moves up and down between the states presented by the liftable TV on the left side of the middle, wherein the built-in foot cavity 109 is fully exposed when the liftable TV 102 is in the raised position; the horizontal shifting device 500 is installed in the side cabinet 300 and is configured to drive the triangular cabinet group to switch between the forward and backward positions according to the travel direction of the rail vehicle.

[0074] For example Figures 3 to 9 As shown, in this embodiment, the side cabinet 300 includes a side cabinet body 301 installed on the inner side wall of the business class cabin, and a side cabinet body armrest 311 and a side cabinet base frame 331 respectively installed on the top and bottom of the side cabinet body 301; a pair of triangular cabinets 100 are fixed together by an upper connecting bracket 201 and a lower connecting bracket 203, wherein the upper connecting bracket 201 is fixedly connected to the work surface 101 of the pair of triangular cabinets 100 at both ends, and the lower connecting bracket 203 is fixedly connected to the support base 103 of the pair of triangular cabinets 100 at both ends.

[0075] like Figures 7 to 9As shown, in this embodiment, guide rails 321 are installed on both the main armrest 311 and the base frame 331 of the side cabinet; sliders 341 that are slidably connected to the guide rails 321 are installed on the work surface 101 and support base 103 of each triangular cabinet 100. Figure 5 and Figure 6 As shown, and with reference Figure 3 and Figure 4 In this embodiment, the horizontal displacement device 500 includes a drive motor 501, a wire rope 503, a wire rope winding wheel 505, multiple wire rope winding wheels 507, and a wire rope crimping seat 509. The wire rope crimping seat 509 is mounted on the upper connecting bracket 201 and crimps the wire rope 503. The drive motor 501 drives the wire rope winding wheel 505 to rotate, causing the wire rope 503 to move clockwise or counterclockwise, thereby moving the upper connecting bracket 201 and subsequently causing the triangular cabinet assembly to move horizontally. When the upper connecting bracket 201 moves the two triangular cabinets 100 via the wire rope 503, the triangular cabinets 100 move relative to the side cabinet 300 via the slider guide rail structure.

[0076] For example Figure 5 and Figure 6 As shown, in this embodiment, the main body 301 of the side cabinet is equipped with three limit sensors 502, and the wire rope crimping seat 509 is equipped with a limit sensor plate 504, thereby forming three motion limits to prevent the triangular cabinet assembly from moving too much and causing collisions.

[0077] like Figure 10 and Figure 17 As shown, in this embodiment, the triangular cabinet 100 is configured to be movably installed on the inside of the rail vehicle's carriage. The triangular cabinet includes a work surface 101, a support base 103, a central column assembly 105, two side column assemblies 107, and a built-in foot cavity 109. The triangular cabinet 100 also includes a liftable television 102 located between the central column assembly 105 and each side column assembly 107 and movably mounted on both, and a lifting drive mechanism 104 corresponding to each liftable television 102.

[0078] In this embodiment, when the rail vehicle moves forward, the rearward-facing side of the triangular cabinet 100 (e.g.) Figure 11The liftable television 102 on the left side of the triangular cabinet 100 can be raised (i.e., in the raised position), exposing the built-in footwell 109 on that side. Passengers on seats on that side can then watch television and place their feet inside the built-in footwell 109. At this time, the liftable television 102 on the forward-facing side of the triangular cabinet 100 lowers to a stowed position. When the rail vehicle reverses direction (i.e., moves backward), the liftable television 102 on the other side of the triangular cabinet can be raised, exposing the built-in footwell on that other side. Passengers on seats on that other side can then watch television and place their feet inside the built-in footwell 109. At this time, the liftable television 102 on the rearward-facing side of the triangular cabinet 100 lowers to a stowed position. In other words, the raising and lowering of the liftable television 102 enables the reversal of the direction of the built-in footwell 109.

[0079] Of course, if the rail vehicle needs to change direction, in order to adjust the length of the built-in foot cavity 109 after the change of direction, that is, to adjust the distance between the passenger seat and the built-in foot cavity 109, it is necessary to first move the front and rear positions of the triangular cabinet so that the passenger using the liftable TV 102 on the other side and the built-in foot cavity 109 can have a suitable distance relative to the triangular cabinet 100.

[0080] It should be noted that, as Figure 12 As shown, in this embodiment, in order to increase the wear resistance and wipeability of the support base 103, a wear-resistant foot pad covering 113 is provided on its top.

[0081] like Figure 12 As shown, in this embodiment, the liftable TV 102 is movably connected to the side column assembly 107 and the center column assembly 105 via the lifting assembly 106. The lifting drive mechanism 104 is configured to drive the lifting assembly 106 to move the liftable TV 102 up and down.

[0082] like Figure 13 and Figure 14 As shown, and with reference Figure 16 In this embodiment, the lifting drive mechanism 104 includes a drive motor 114, a wire rope 134, a wire rope winding wheel 154, a wire rope adapter bearing 174, and a wire rope winding wheel 194. The drive motor 114 is installed in the support base 103 and drives the wire rope winding wheel 154 to rotate so that the wire rope 134 moves clockwise or counterclockwise. The wire rope adapter bearing 174 and the wire rope winding wheel 194 are respectively installed below and above the central column assembly 105.

[0083] like Figure 15 As shown, and with reference Figure 13 , Figure 14 and Figure 16In this embodiment, the lifting assembly 106 includes a synchronous shaft assembly 116 and fixed seats 136 located at both ends of the synchronous shaft assembly. The synchronous shaft assembly 116 meshes with the gear racks of the side column assembly 107 and the central column assembly 105 at its two ends, respectively. Each fixed seat 136 is slidably connected to the side column assembly 107 and the central column assembly 105, respectively. The fixed seat 136 of the lifting assembly 106 connected to the central column assembly 105 is provided with a wire rope groove 1360 and a wire rope pressure plate 156 installed on the fixed seat 136 at the position of the wire rope groove 1360 and pressing the wire rope 134, thereby driving the lifting assembly 106 to move when the wire rope 134 moves.

[0084] like Figure 16 As shown, in this embodiment, the central column assembly 105 includes a central column 115, a pair of racks 135 mounted on the central column, and a pair of guide rails 155, the pair of guide rails 155 being located on both sides of the pair of racks 135.

[0085] like Figure 17 As shown, in this embodiment, the side column assembly 107 includes a side column 117, a rack 137 mounted on the side column 117, and a guide rail 157, wherein the guide rail 157 and the rack 137 are symmetrically arranged with the corresponding guide rail 155 and rack 135 on the central column 105.

[0086] For example Figure 15 As shown, in the lifting assembly 106 of this embodiment, the synchronous shaft assembly 116 includes a synchronous shaft 126 rotatably mounted on a fixed base 136 at both ends, and a gear 146 fixedly mounted on both ends of the synchronous shaft 126, located outside the fixed base 136, and meshing with a rack (see reference numerals 135 and 137 in the figure); wherein, a slider 165 adapted to the guide rail is mounted on the side of the fixed base 136 facing the guide rail (see reference numerals 155 and 157 in the figure). Figure 14 and Figure 16 ) and slider 167 (see Figure 17 ).

[0087] For example Figure 15 As shown, in this embodiment, the lifting assembly 106 further includes a maintenance cover 186, which is detachably mounted on the mounting base 136 at both ends. Additionally, the synchronous shaft 126 is rotatably mounted on the mounting base 136 at both ends via needle roller bearings 196.

[0088] For example Figure 16 As shown, and with reference Figure 12As shown, in this embodiment, the central column 115 is also equipped with a TV roller assembly 195 including a TV roller 185. The liftable TV 102 has a housing groove (not shown) on its housing that is slidably connected to the TV roller 185. Through the cooperation between the TV roller 185 and the housing groove, the TV roller 185 plays an auxiliary sliding role during the lifting and lowering process of the liftable TV 102.

[0089] It should also be noted that the device that ensures the forward and backward movement of the triangular cabinet 100 will be described in a separate patent application. The design of this part is not the focus of innovation of this patent application, so it will not be described in detail in this article.

[0090] The following is for reference. Figures 10 to 17 The lifting process of the height-adjustable TV 102 in the triangular cabinet 100 of this embodiment is described below:

[0091] The wire rope winding wheel 154 drives the wire rope 134 to move through the operation of the drive motor 114. The wire rope pressure plate 156 and the fixed seats 136 at both ends of the lifting assembly 106 tightly press the wire rope 134. When the wire rope 134 moves, it can drive the lifting assembly 106 to move up and down.

[0092] Specifically, the sliders installed on the fixed seats 136 at both ends of the lifting assembly 106 will slide along the guide rail 157 on the side column 117 and the guide rail 155 on the center column 115 at the same time; at the same time, the gears at both ends of the synchronous shaft assembly 116 of the lifting assembly 106 will roll along the rack 137 on the side column 117 and the rack 135 on the center column 115 at the same time.

[0093] The synchronous shaft assembly 116 is designed so that the gears 146 at both ends mesh with the racks on each column, ensuring that both ends of the lifting assembly 106 are always in a horizontal position, guaranteeing smoothness and usability, and realizing the lifting function of the liftable TV 102 fastened to the lifting assembly 106.
