Description

Technical Field

[0001] At least one embodiment of this disclosure relates to the field of seat technology for rail vehicles, and more specifically, to a seat bracket, seat, and rail vehicle for rail vehicles. Background Technology

[0002] As the speed rating of rail vehicles increases, higher requirements are placed on the lightweighting of various internal components. Seat assemblies, as a widely used structure in rail vehicles, have become one of the key targets for lightweighting.

[0003] Existing seat frames for rail vehicles are typically made of welded carbon steel and consist of aluminum alloy panels, foot pedals, and other components to form a frame assembly. The large structural mass of the frame increases the friction between the rail vehicle and the track during operation, which is detrimental to increasing the speed of the rail vehicle.

Figure 2 This is a three-dimensional installation diagram of a seat bracket and seat body for a rail vehicle according to an embodiment of the present disclosure; Figure 3 yes Figure 2 A magnified view of part A in the middle; Figure 4 yes Figure 2 A magnified view of part B in the middle section; Figure 5 This is a perspective view of a seat bracket for a rail vehicle according to an embodiment of the present disclosure; Figure 6 This is a perspective view of a support frame for a seat bracket of a rail vehicle according to an embodiment of the present disclosure.

[0068] According to exemplary embodiments of this disclosure, please refer to Figures 1-6 A seat support for a rail vehicle is provided, comprising at least one support leg 1 and a support frame 2. Each support leg 1 extends in the height direction and its lower end is mounted on the floor 51 inside the carriage 5. The support frame 2 extends in the horizontal plane and is mounted on the upper end of the support leg 1. The support frame 2 includes a core material 21, a frame 22, and two mounting mechanisms 23. The core material 21 is made of a hollow honeycomb structured sheet material. The frame 22 covers the outside of the core material 21. The two mounting mechanisms 23 are respectively mounted on both sides of the support frame 2 extending in the longitudinal direction and are configured to hold a seat body 4 on the support frame 2.

[0069] In this embodiment, the seat support includes at least one support leg 1 and a support frame 2. The support frame 2 includes a core material 21, a frame 22, and two mounting mechanisms 23. The core material 21 is made of a hollow honeycomb structure plate, and the frame 22 covers the outside of the core material 21. The two mounting mechanisms 23 are respectively installed on both sides of the support frame 2 extending in the longitudinal direction and are configured to hold the seat body 4 on the support frame 2, thereby reducing the weight of the seat support itself and achieving a lightweight design of the seat assembly, which is beneficial to improving the travel speed of the rail vehicle.

[0070] Figure 7 This is a three-dimensional installation diagram of the core material and frame of the support frame for a seat bracket for a rail vehicle according to an embodiment of this disclosure; Figure 8 This is a perspective view of the core material of the support frame for a seat bracket of a rail vehicle according to an embodiment of the present disclosure; Figure 9 This is a perspective view of the first and second sealing edges of the support frame for a seat bracket of a rail vehicle according to an embodiment of the present disclosure. Figure 10 This is a cross-sectional schematic diagram of the core material of the support frame for a seat bracket of a rail vehicle according to an embodiment of this disclosure.

[0071] In some exemplary embodiments, reference is made to Figures 7-10 The core material 21 is constructed as a honeycomb structure plate formed by multiple first cell structures 213 with approximately hexagonal cross sections. The frame 22 includes two first skins 221, which cover the upper surface, the lower surface, and the sidewall between the upper and lower surfaces of the core material 21, respectively.

[0072] In this embodiment, by constructing the core material 21 into a flat plate with a honeycomb structure formed by multiple first cell structures 213 with approximately hexagonal cross sections, the weight of the seat frame itself is reduced to achieve a lightweight design of the seat assembly, while also ensuring the rigidity of the seat frame.

[0073] It should be noted that in this embodiment, a second sealing edge 222 can also be used to cover the side wall of the core material 21, and the two sides of the second sealing edge 222 extending in the height direction can be connected to the two first skins 221 respectively.

[0074] Furthermore, the thickness D4 of the core material 21 is 20-40 mm, preferably 30 mm. The thickness of the first skin 221 is 0.5-1.5 mm, preferably 1 mm. The thickness of the second edge seal 222 is 0.5-1.5 mm, preferably 1 mm. The side length L1 of the first cell structure 213 is 7-9 mm, preferably 8 mm. The wall thickness D1 of the first cell structure 213 is 0.05-0.15 mm, preferably 0.1 mm.

[0075] Figure 11 This is a perspective view of a mounting mechanism for a seat bracket for a rail vehicle, which is mounted on one side of a support frame, according to an embodiment of this disclosure. Figure 12 This is a perspective view of a mounting mechanism for a seat bracket for a rail vehicle, which is mounted on the other side of a support frame, according to an embodiment of the present disclosure.

[0076] In some exemplary embodiments, reference is made to Figures 2-6 as well as Figures 11-12 Each mounting mechanism 23 is also configured to prevent the seat body 4 from tipping over in the lateral direction relative to the support frame 2.

[0077] In some exemplary embodiments, reference is made to Figures 2-6 as well as Figures 11-12 The seat body 4 includes two transverse beams 42 extending in the lateral direction and two longitudinal beams 41 installed between the two ends of the transverse beams 42. Each longitudinal beam 41 is equipped with at least two limiting rods 43 movable relative to the transverse beams 42. Each mounting mechanism 23 includes two sets of connecting mechanisms 231 and a connecting portion 232. The two sets of connecting mechanisms 231 are mounted facing each other on both sides of the support frame 2 extending in the longitudinal direction. The connecting portion 232 connects between the two sets of connecting mechanisms 231 and extends out of the support frame 2 in the lateral direction. The limiting rods 43 extend horizontally toward the connecting mechanisms 231 at the lower part of the connecting portion 232 and are detachably in contact with the connecting mechanisms 231 to hold the seat body 4 on the support frame 2 and prevent the seat body 4 from tipping over and / or moving in the lateral direction relative to the support frame 2.

[0078] With the above-described configuration, when the limiting rod 43 extends horizontally towards the connecting mechanism 231 from the lower part of the connecting part 232 and contacts the connecting mechanism 231, the connecting mechanism 231 prevents the limiting rod 43 from moving in the lateral and longitudinal directions, thereby holding the seat body 4 on the support frame 2 and preventing the seat body 4 from tipping over and / or moving in the lateral direction relative to the support frame 2. The overturning torque generated in this process is transmitted to the floor 51 of the carriage 5 through the support frame 2 and the support leg 1.

[0079] It should be noted that in this embodiment, the longitudinal direction refers to the direction of travel of the rail vehicle, and the transverse direction refers to the width direction of the rail vehicle.

[0080] In some exemplary embodiments, reference is made to Figures 2-6 as well as Figures 11-12 Each connecting mechanism 231 includes two cantilever arms 2311 and a support portion 2312. The two cantilever arms 2311 are respectively mounted on the upper and lower surfaces of the support frame 2. The support portion 2312 includes a base 2313 and a protrusion 2314. The base 2313 is connected between the two cantilever arms 2311 and abuts against the side of the support frame 2. The protrusion 2314 is provided on the base 2313 and protrudes away from the support frame 2. Two limiting rods 43 are simultaneously and movably extended into the protrusion 2314 from either the outer or inner side to near the base 2313, thereby restricting the lateral movement of the seat body 4 relative to the support frame 2.

[0081] In this embodiment, two cantilever arms 2311 extend from the support frame 2 in the lateral direction. When the two limiting rods 43 simultaneously extend into the base 2313 from the outside or inside of the protrusion, the cantilever arms 2311 are located above the limiting rods 43 to restrict the movement of the limiting rods 43 in the height direction. The protrusion 2314 restricts the movement of the limiting rods 43 in the longitudinal direction, and the base 2313 restricts the movement of the limiting rods 43 in the lateral direction.

[0082] Figure 13 This is a three-dimensional installation diagram of a seat bracket and footrest for a rail vehicle according to an embodiment of the present disclosure.

[0083] In some exemplary embodiments, reference is made to Figures 5-6 as well as Figure 13 The support frame 2 also has a mounting bracket 24 on one side extending in the lateral direction, which is suitable for mounting the foot pedal 6. The foot pedal 6 is connected to the limit rod 43 so that the seat body 4 can be turned by operating the foot pedal 6.

[0084] In this embodiment, the foot pedal 6 is connected to the limiting rod 43. When the user presses the foot pedal 6, the limiting rod 43 moves towards the outside of the support frame 2, causing the limiting rod 43 to disengage from the connecting mechanism 231, thereby separating the seat body 4 from the seat bracket to allow the seat body 4 to turn.

[0085] Figure 14 This is a perspective view of a mounting bracket for a seat support of a rail vehicle according to an embodiment of the present disclosure.

[0086] In some exemplary embodiments, reference is made to Figure 5 as well as Figure 14 The mounting bracket 24 includes a base plate 241 and two baffles 242. The base plate 241 is mounted on the lower side of the support frame 2. The two baffles 242 are mounted on the base plate 241 and form a notch 243 on the side of the base plate 241 that extends out of the support frame 2, which is adapted to allow the pedal 6 to extend and restrict the pedal 6 to move in the longitudinal direction.

[0087] In this embodiment, the baffle 242 is configured as a flat plate that extends downward along the height direction from one side of the base plate 241 extending out of the support frame 2 and is arranged parallel to the longitudinal vertical plane.

[0088] Furthermore, a reinforcing plate 244 is connected to one side of the baffle 242 extending in the longitudinal direction. The reinforcing plate 244 extends in the transverse vertical plane and is connected to one side of the base plate 241 extending in the longitudinal direction to reinforce the baffle 242 and prevent the baffle 242 from breaking.

[0089] Figure 15 This is a perspective view of the pivot sleeve of the steering portion of a seat bracket for a rail vehicle according to an embodiment of the present disclosure.

[0090] In some exemplary embodiments, reference is made to Figures 2-5 as well as Figure 15 The seat bracket also includes a steering part 3. The steering part 3 is rotatably mounted on the top of the support frame 2, which is suitable for rotatably mounting the seat body 4 on the support frame 2 via the steering part 3.

[0091] In some exemplary embodiments, reference is made to Figure 2 The steering unit 3 includes a pivot sleeve 31 and a pivot shaft 32. The pivot sleeve 31 is mounted on the top of the support frame 2. The pivot shaft 32 extends along the height direction, with one end rotatably mounted on the pivot sleeve 31 and the other end mounted on the seat body 4.

[0092] In this embodiment, the seat body 4 can rotate relative to the support frame 2 through the cooperation of the rotating shaft 32 and the rotating shaft sleeve 31, so that the seat body 4 can be rotatably mounted on the seat bracket.

[0093] In some exemplary embodiments, reference is made to Figures 2-9 The core material 21 has a roughly circular mounting hole 211 near its center, which is suitable for mounting the steering part 3. The core material 21 has a roughly rectangular opening 212 on the side away from the center. A first sealing edge 223 is mounted on the inner wall of the opening 212. The two sides of the first sealing edge 223 extending in the height direction are respectively connected to two first skins 221, which are suitable for accommodating circuit elements for connection to an external power supply.

[0094] It should be noted that the thickness of the first edge seal 223 is 0.5-1.5mm, preferably 1mm.

[0095] In some exemplary embodiments, reference is made to Figures 16-20 The support leg 1 includes a support column 11 and a housing 12. The support column 11 is made of a hollow honeycomb structure column. The housing 12 covers the outside of the support column 11.

[0096] In some exemplary embodiments, reference is made to Figures 16-20 The support column 11 is constructed as a column with a honeycomb structure formed by multiple second cell structures 14 with approximately hexagonal cross sections. The shell 12 includes a second skin 121, which covers the outer wall of the support column 11.

[0097] It should be noted that, in this embodiment, by constructing the support column 11 as a column with a honeycomb structure formed by multiple second cell structures 14 with approximately hexagonal cross sections, the weight of the seat frame itself is further reduced while ensuring the rigidity of the seat frame, so as to achieve a lightweight design of the seat assembly.

[0098] It should be noted that, in this embodiment, the height H1 of the support column 11 is 210-230 mm, preferably 219 mm. The thickness of the second skin 121 is 0.5-1.5 mm, preferably 1 mm. The side length L2 of the second cell structure 14 is 7-9 mm, preferably 8 mm. The wall thickness D2 of the second cell structure 14 is 0.05-0.15 mm, preferably 0.1 mm.

[0099] Figure 16 This is a perspective view of a seat bracket for a rail vehicle according to an embodiment of the present disclosure, showing a support leg mounted on the side of the support frame away from the steering section. Figure 17 This is a perspective view of a seat bracket for a rail vehicle according to an embodiment of the present disclosure, showing a support leg mounted on the side of a support frame near the steering section. Figure 18 This is a perspective view of a first embodiment of a mounting component for a seat bracket of a rail vehicle according to an embodiment of the present disclosure; Figure 19 This is a perspective view of a second embodiment of the mounting component for a seat bracket of a rail vehicle according to the present disclosure; and Figure 20This is a schematic cross-sectional view of the support column of the support leg of the seat bracket for a rail vehicle according to a disclosed embodiment.

[0100] In some exemplary embodiments, reference is made to Figure 2 as well as Figures 16-20 The seat support includes two support legs 1 arranged facing each other in the lateral direction, and the cross-sectional area of ​​the support leg 1 closer to the steering part 3 is larger than the cross-sectional area of ​​the support leg 1 farther away from the steering part 3.

[0101] It should be noted that in this embodiment, during the rotation of the seat body 4 relative to the seat bracket, the position near the steering part 3 needs to bear a larger torque. Therefore, the cross-sectional area of ​​the support leg 1 near the steering part 3 should be larger than the cross-sectional area of ​​the support leg 1 away from the steering part 3 in order to meet the load-bearing requirements of the support leg 1.

[0102] In other words, the seat bracket near the steering part 3 needs to bear the load of the seat body 4 in the vertical direction, as well as the load in the longitudinal and lateral directions generated during the rotation of the seat body 4. However, the side of the seat bracket away from the steering part 3 mainly bears the load of the seat body 4 in the vertical direction. Therefore, in this embodiment, the cross-sectional area of ​​the support leg 1 installed near the steering part 3 is larger than the cross-sectional area of ​​the support leg 1 installed away from the steering part 3.

[0103] It should be noted that, in this embodiment, the support leg 1 further includes two mounting components 13, which are respectively installed at both ends of the support column 11 extending in the height direction. The two mounting components 13 are respectively adapted to connect with the floor 51 inside the carriage 5 and the support frame 2. The mounting components 13 are constructed as thin plates that are generally rectangular, L-shaped, or T-shaped.

[0104] In this embodiment, the lower side of the support column 11 is connected to the floor 51 of the carriage 5 via a generally rectangular mounting member 13. The upper side of the support column 11 mounted on the side of the support frame 2 away from the steering section 3 is connected to the support frame 2 via a generally L-shaped mounting member 13. The upper side of the support column 11 mounted on the support frame 2 near the steering section 3 is connected to the support frame 2 via a generally T-shaped mounting member 13. The thickness D3 of the mounting member 13 is 3-5 mm, preferably 4 mm.

[0105] It should be noted that in this embodiment, the core material 21 and the support column 11 are made of aluminum alloy, titanium alloy, or magnesium alloy. Preferably, aluminum alloy is used. Hollow aluminum honeycomb structure panels supported by aluminum alloy have the characteristics of low density, high specific stiffness, high specific strength, and good vibration damping and energy absorption.

[0106] Furthermore, to meet the design requirements for lightweight seats in rail vehicles, existing technologies have proposed an integrated die-cast magnesium alloy seat bracket structure, which simplifies the manufacturing process of the seat bracket assembly and achieves material lightweighting, but does not achieve structural lightweighting. In this embodiment, the core material 21 made of hollow honeycomb structure plate and the support column 11 are used as the main load-bearing structures of the support plate and support leg 1, respectively, thus achieving structural lightweighting of the seat bracket.

[0107] Furthermore, the seat bracket for rail vehicles in this embodiment has the following advantages:

[0108] 1. The core material 21 and the support column 11, made of hollow honeycomb structure plate, are used as the main load-bearing structure of the support frame 2 and the support leg 1. The side length and thickness parameters of the first cell structure 213 of the core material 21 and the second cell structure 14 of the support column 11 are optimized to meet the stiffness requirements of the seat load.

[0109] 2. The support leg 1 and support frame 2 adopt a split assembly structure, which makes the support leg 1 and support frame 2 independently formed, easy to modular production, simple to assemble, and has high precision in controlling the forming deformation of the support leg 1 and support frame 2.
