[0068] According to an exemplary embodiment of the present disclosure, please refer to Figure 1-Figure 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 a height direction, and the lower end is mounted on a floor 51 inside a car 5. The support frame 2 extends in a horizontal plane and is mounted on the upper end of the support leg 1. The support frame 2 comprises a core material 21, a frame 22 and two mounting mechanisms 23. The core material 21 is made of a plate material with a hollow honeycomb structure. The frame 22 is coated on 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 the 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, the frame 22 is coated on the outside of the core material 21, and 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 keep the seat body 4 on the support frame 2, reducing the mass of the seat support itself, so as to achieve a lightweight design of the seat assembly, which is beneficial to the improvement of the travel speed of the rail vehicle.

[0070] Figure 7 It is a three-dimensional installation diagram of a core material and a frame of a support frame of a seat support for a rail vehicle according to an embodiment of the present disclosure; Figure 8 is a three-dimensional schematic diagram of a core material of a support frame of a seat support for a rail vehicle according to an embodiment of the present disclosure; Fig. 9 is a three-dimensional schematic diagram of a first edge seal and a second edge seal of a support frame of a seat support for a rail vehicle according to an embodiment of the present disclosure; Fig.10 4 is a schematic cross-sectional view of a core material of a support frame of a seat bracket for a rail vehicle according to an embodiment of the present disclosure.

[0071] In some exemplary embodiments, referring to Figure 7-10 The core material 21 is constructed as a flat plate with a honeycomb structure formed by a plurality of first cell structures 213 with roughly hexagonal cross-sections. The frame 22 includes two first skins 221, which respectively cover the upper surface, the lower surface, and the side wall between the upper surface and the lower surface of the core material 21.

[0072] In this embodiment, the core material 21 is constructed into a flat plate with a honeycomb structure formed by a plurality of first cell structures 213 with roughly hexagonal cross-sections. On the one hand, the mass of the seat frame itself is reduced to achieve a lightweight design of the seat assembly, and on the other hand, the rigidity of the seat frame is ensured.

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

[0074] Further, 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] Fig.11 is a three-dimensional schematic diagram of a mounting mechanism of a seat bracket for a rail vehicle installed on one side of a support frame according to an embodiment of the present disclosure; Fig.12 It is a three-dimensional schematic diagram of a mounting mechanism of a seat bracket for a rail vehicle installed on the other side of a support frame according to an embodiment of the present disclosure.

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

[0077] In some exemplary embodiments, referring to Figure 2-Figure 6 as well as Figure 11-Figure 12 The seat body 4 includes two cross beams 42 extending in the transverse direction and two longitudinal beams 41 installed between the two ends of the cross beams 42. Each longitudinal beam 41 is installed with at least two limit rods 43 movable relative to the cross beams 42. Each mounting mechanism 23 includes two groups of connecting mechanisms 231 and a connecting portion 232. The two groups of connecting mechanisms 231 are installed facing each other on both sides of the support frame 2 extending in the longitudinal direction. The connecting portion 232 is connected between the two groups of connecting mechanisms 231 and extends out of the support frame 2 in the transverse direction. Among them, the limit rod 43 extends horizontally toward the connecting mechanism 231 at the lower part of the connecting portion 232 and can be detachably contacted with the connecting mechanism 231 to keep the seat body 4 on the support frame 2 and prevent the seat body 4 from tipping over and / or moving in the transverse direction relative to the support frame 2.

[0078] Through the above-mentioned arrangement, when the limit rod 43 extends horizontally toward the connecting mechanism 231 at the lower part of the connecting part 232 and contacts with the connecting mechanism 231, the limit rod 43 is prevented from moving in the lateral and longitudinal directions under the action of the connecting mechanism 231, thereby keeping 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, and transmitting the overturning torque generated in this process to the floor 51 of the car 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 traveling direction of the rail vehicle, and the transverse direction refers to the width direction of the rail vehicle.

[0080] In some exemplary embodiments, referring to Figure 2-Figure 6 as well as Figure 11-Figure 12 Each set of connecting mechanisms 231 includes two cantilevers 2311 and a support portion 2312. The two cantilevers 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 cantilevers 2311 and abuts against the side of the support frame 2. The protrusion 2314 is arranged on the base 2313 and protrudes away from the support frame 2. Among them, the two limit rods 43 are respectively and simultaneously movably extended to the base 2313 on the outside or inside of the protrusion 2314 to limit the movement of the seat body 4 relative to the support frame 2 in the lateral direction.

[0081] In this embodiment, the two cantilevers 2311 extend out of the support frame 2 in the lateral direction. When the two limit rods 43 simultaneously extend into the outer side or inner side of the protrusion to close to the base 2313, the cantilever 2311 is located on the upper side of the limit rod 43 to limit the movement of the limit rod 43 in the height direction. The protrusion 2314 limits the movement of the limit rod 43 in the longitudinal direction, and the base 2313 limits the movement of the limit rod 43 in the lateral direction.

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

[0083] In some exemplary embodiments, referring to Figure 5-Figure 6 as well as Fig.13 A mounting bracket 24 is also installed on one side of the support frame 2 extending in the lateral direction, which is suitable for installing a foot pedal 6. The foot pedal 6 is connected to a limiting rod 43 to allow the seat body 4 to turn by operating the foot pedal 6.

[0084] In this embodiment, the foot pedal 6 is connected to the limit rod 43. When the user steps on the foot pedal 6, the limit rod 43 is driven to move toward the outside of the support frame 2, so that the limit rod 43 disengages from the connecting mechanism 231, thereby separating the seat body 4 from the seat bracket to allow the seat body 4 to turn.

[0085] Fig.14 It is a three-dimensional schematic diagram of a mounting bracket of a seat bracket for a rail vehicle according to an embodiment of the present disclosure.

[0086] In some exemplary embodiments, referring to Figure 5 as well as Fig.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 extending out of the support frame 2, which is suitable for allowing the pedal 6 to extend and limiting the movement of the pedal 6 in the longitudinal direction.

[0087] In this embodiment, the baffle 242 is configured as a flat plate extending from one side of the base plate 241 extending out of the support frame 2 downward in the height direction and 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 a 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] Fig.15 It is a three-dimensional schematic diagram of a rotating shaft sleeve of a steering part of a seat bracket of a rail vehicle according to an embodiment of the present disclosure.

[0090] In some exemplary embodiments, referring to Figure 2-Figure 5 as well as Fig.15 The seat support further comprises a steering portion 3. The steering portion 3 is rotatably mounted on the top of the support frame 2, and is suitable for enabling the seat body 4 to be rotatably mounted on the support frame 2 through the steering portion 3.

[0091] In some exemplary embodiments, referring to Figure 2 The steering part 3 includes a rotating shaft sleeve 31 and a rotating shaft 32. The rotating shaft sleeve 31 is installed on the top of the support frame 2. The rotating shaft 32 extends in the height direction, one end of which is rotatably installed on the rotating shaft sleeve 31, and the other end is installed on the seat body 4.

[0092] In this embodiment, the seat body 4 can rotate relative to the support frame 2 through the cooperation between 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, referring to Figure 2-Figure 9 A substantially circular mounting hole 211 is formed in the area near the center of the core material 21, and the mounting hole 211 is suitable for mounting the steering portion 3. A substantially rectangular opening 212 is formed on one side of the core material 21 away from the center, and a first edge seal 223 is installed on the inner wall of the opening 212. The first edge seal 223 is respectively connected to the two first skins 221 on both sides extending in the height direction, and is suitable for accommodating circuit components for connecting to an external power source.

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

[0095] In some exemplary embodiments, referring to Figure 16-Figure 20 The support leg 1 comprises a support column 11 and a shell 12. The support column 11 is made of a hollow honeycomb structure column. The shell 12 is coated on the outside of the support column 11.

[0096] In some exemplary embodiments, referring to Figure 16-Figure 20 The support column 11 is constructed as a column with a honeycomb structure formed by a plurality of second cell structures 14 with roughly hexagonal cross-sections. The shell 12 includes a second skin 121 covering the outer side wall of the support column 11 .

[0097] It should be noted that, in this embodiment, by constructing the support column 11 into a column with a honeycomb structure formed by multiple second cell structures 14 with roughly hexagonal cross-sections, the mass of the seat bracket itself is further reduced while ensuring the rigidity of the seat bracket, 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] Fig.16 is a three-dimensional schematic diagram of a support leg of a seat support for a rail vehicle installed on a side of a support frame away from a steering portion according to an embodiment of the present disclosure; Fig.17 is a three-dimensional schematic diagram of a support leg of a seat support for a rail vehicle installed on a side of a support frame close to a steering portion according to an embodiment of the present disclosure; Fig.18 is a perspective schematic diagram of a first embodiment of a mounting component for a seat bracket of a rail vehicle according to an embodiment of the present disclosure; Fig.19 is a perspective schematic diagram of a second embodiment of a mounting component for a seat bracket of a rail vehicle according to an embodiment of the present disclosure; and Fig. 20The invention is a schematic cross-sectional view of a support column of a support leg of a seat support for a rail vehicle according to a disclosed embodiment.

[0100] In some exemplary embodiments, referring to Figure 2 as well as Figure 16-Figure 20 The seat support includes two supporting legs 1 arranged facing each other in a transverse direction, and the cross-sectional area of ​​the supporting leg 1 close to the turning portion 3 is larger than the cross-sectional area of ​​the supporting leg 1 away from the turning portion 3.

[0101] It should be noted that, in the present embodiment, during the rotation of the seat body 4 relative to the seat frame, the position close to the steering portion 3 needs to withstand a larger torque. Therefore, the cross-sectional area of ​​the support leg 1 close to the steering portion 3 is larger than the cross-sectional area of ​​the support leg 1 away from the steering portion 3 to meet the load-bearing requirements of the support leg 1.

[0102] In other words, the position of the seat bracket close to the steering portion 3 needs to bear the load of the seat body 4 in the vertical direction and the loads in the longitudinal and lateral directions generated during the rotation of the seat body 4, while the side edge of the seat bracket away from the steering portion 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 at the position of the seat bracket close to the steering portion 3 is larger than the cross-sectional area of ​​the support leg 1 installed at the position of the seat bracket away from the steering portion 3.

[0103] It should be noted that, in this embodiment, the support leg 1 further includes two mounting components 13, which are respectively mounted at both ends of the support column 11 extending in the height direction, and the two mounting components 13 are respectively suitable for connecting with the floor 51 inside the compartment 5 and the support frame 2. The mounting component 13 is configured as a substantially rectangular, L-shaped or T-shaped thin plate.

[0104] In this embodiment, the lower side of the support column 11 is connected to the floor 51 of the compartment 5 through a substantially rectangular mounting component 13, the upper side of the support column 11 installed on the side of the support frame 2 away from the steering portion 3 is connected to the support frame 2 through a substantially L-shaped mounting component 13, and the upper side of the support column 11 installed on the support frame 2 close to the steering portion 3 is connected to the support frame 2 through a substantially T-shaped mounting component 13. The thickness D3 of the mounting component 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 one of aluminum alloy, titanium alloy and magnesium alloy. Among them, aluminum alloy is preferably used. The hollow aluminum honeycomb structure plate supported by aluminum alloy has the characteristics of low density, high specific stiffness, high specific strength, good vibration reduction and energy absorption, etc.

[0106] Furthermore, in order to meet the design requirements of lightweight seats for rail vehicles, the prior art proposes an integrated die-cast magnesium alloy seat bracket structure, which simplifies the preparation process of the seat bracket assembly and achieves lightweight materials, but does not achieve lightweight structure.
