Description
Technical Field
[0001] The present invention relates to the technical field of rail transit seats, and in particular to a centralized control rotation system for small-gap seats in a high-speed rail passenger compartment and a steering method thereof. Background Art
[0002] To ensure that the passenger compartment seats (first-class seats, second-class seats, business seats, and commercial seats) of existing rail transit trains always ensure that the passengers' sitting direction is consistent with the train's travel direction, the passenger compartment seats (first-class seats, second-class seats, and commercial seats) can all rotate 180 degrees. Currently, the passenger compartment seats (first-class seats, second-class seats, and commercial seats) of rail transit trains all have the function of rotating the seats 180 degrees. When rotation is required, the side footrest located on the aisle side of the seat is manually stepped on to return the footrest to its initial position; while stepping on the footrest, the footrest limit wheel on the footrest moves downward, separating the seat base and the rotating frame, and the rotating frame is manually rotated 180 degrees clockwise or counterclockwise (to be confirmed according to the direction of the seat and the train's travel).
[0003] To prevent interference between seats during rotation, large gaps are typically left between them. This results in inefficient space utilization and difficulty increasing passenger capacity. However, if the gaps between seats are reduced, adjacent seats will collide during rotation, preventing a full 180° rotation. Summary of the Invention

[0017] Furthermore, a follower plate is mounted on the bottom of the seat shaft; a first metal sensor and a second metal sensor are provided on one side of the reduction gearbox; and a first metal sensor sheet and a second metal sensor sheet are provided on the follower plate.
[0018] The present invention also provides the following technical solution: a method for rotating seats with small gaps in a high-speed rail passenger compartment, including the above-mentioned centralized control rotation system for seats with small gaps in a high-speed rail passenger compartment, comprising the following steps:
[0019] (a1) when any of the high-speed rail seats needs to be rotated, the chair frames of the high-speed rail seats adjacent to the high-speed rail seat are respectively moved away from the high-speed rail seat by a preset distance;
[0020] (a2) Rotate the seat frame of the high-speed rail seat that needs to be rotated 180°.
[0021] (a3) Moving the chair frames of the high-speed rail seats adjacent to the high-speed rail seat that needs to be rotated so that they return to their original central positions.

[0037] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0038] like Figure 1As shown, a high-speed rail passenger compartment seat centralized control rotation system includes a plurality of high-speed rail seats 2 arranged in a passenger compartment 1. The high-speed rail seats 2 are arranged in a row along the front-to-back direction on the left and right sides of the passenger compartment 1. In this embodiment, eighteen high-speed rail seats 2 are arranged on each side of the passenger compartment 1.
[0039] like Figure 2 As shown, each high-speed train seat 2 comprises a base 21 and a seat frame 22. The base 21 is provided with a sliding component 23 and a rotating component 24. The bottom of the seat frame 22 extends into the base 21 and is connected to the rotating component 24. The rotating component 24 is used to drive the seat frame 22 to rotate. The seat frame 1 can rotate 180 degrees clockwise or counterclockwise depending on the direction of the train's travel. The rotating component 24 is mounted on the sliding component 23, which drives the rotating component 24 and the seat frame 22 to move forward and backward.
[0040] Figure 3 Schematic diagram of the structure of the sliding component 23 of the high-speed rail seat 2 of this embodiment. Figure 2 and Figure 3 As shown, the sliding component 23 includes two slide rails 231, a crossbeam 232, and a movable base 233. The two slide rails 231 are fixed to the base 21. The two slide rails 231 are parallel to each other and each has a rack 234 mounted therein. The two slide rails 231 are located at either end of the crossbeam 232, and the ends of the crossbeam 232 are slidably connected to the slide rails 231 at the same end.
[0041] A gear 235 is installed at each end of the crossbeam 232, and the two gears 235 are respectively meshed with the rack 234 at the same end. A first motor 236 is also provided on the crossbeam 232, and the first motor 236 is connected to the two gears 235 and drives the two gears 235 to rotate. The first motor 236 and the gears 235 are both connected to each other through a flexible drive shaft 237. Since the flexible drive shaft 237 can be bent and deformed, the arrangement position of the first motor 236 is more flexible, which can reduce the installation accuracy requirements and facilitate the installation operation. In addition, since the flexible drive shaft 237 can absorb a certain amount of torque, there will be no sense of frustration when adjusting the high-speed rail seat 2, which improves the comfort of the user.
[0042] The movable base 233 is connected to the top of the crossbeam 232, and the rotating member 24 is set on the movable base 233. The first motor 236 drives the gear 235 to rotate, so that the gear 235 moves on the rack 234, and drives the crossbeam 232 and the movable base 233 to move, thereby moving the rotating member 24 and the chair frame 22 in the forward and backward directions.
[0043] Figure 5 This is an exploded schematic diagram of the rotating component 24 of the high-speed rail seat of this embodiment. Figure 4As shown, a swivel beam 221 is provided at the bottom of the chair frame 22, and the rotating component 24 includes a seat shaft 241, a gear plate 242, and a driving device. The seat shaft 241 is connected to the bottom of the swivel beam 221, and the gear plate 242 is fixedly mounted on the top of the seat shaft 241. The bottom of the seat shaft 241 is mounted on the movable seat 233 via a bearing. The driving device is mounted on the movable seat 233, and the driving device is used to drive the gear plate 242 to rotate. The driving device includes a reduction gear 243 and a second motor 244, and the reduction gear 243 is fixed to the movable seat 233. The second motor 244 is provided on the reduction gear 243. A transmission gear 245 is fixedly mounted on the bevel gear shaft on the reduction gear 243, and the transmission gear 245 is meshed with the gear plate 242.
[0044] A follower plate 246 is also mounted on the bottom of the seat shaft 241. In this embodiment, the follower plate 246 is located below the movable seat 233. A nut 247 is also provided below the follower plate 246. The nut 247 fits over the bottom of the seat shaft 241 to prevent the follower plate 246 from falling off. A reduction gear 243 is also mounted below the movable seat 233. The movable seat 233 has a through hole 238, through which a transmission gear 245 extends to the top of the movable seat 233.
[0045] A first metal inductor 251 and a second metal inductor 252 are provided on one side of the reduction box 243. A first metal inductor sheet 253 and a second metal inductor sheet 254 are provided on the follower plate 246.
[0046] When the chair frame 22 moves to the front or rear, the center of gravity of the chair frame 22 is biased to the front or rear. If the chair frame 22 is rotated at this time, the bottom of the chair frame 22 may break, and the chair frame 22 may fall over, causing a safety accident. Therefore, the chair frame 22 can only be rotated when it is in the original central position. When the rotation conditions of the chair frame 22 are met, the second motor 244 is started, driving the transmission gear 245 through the reduction gear 243, and then driving the gear plate 242. The gear plate 242 then drives the rotating frame crossbeam 221, the chair frame 22, the follower plate 246, the first metal sensor 253, and the second metal sensor 254 to rotate. If the seat has not yet started to rotate, the first metal sensor 253 is located above the first metal sensor 251, and the indicator light of the first metal sensor 251 is always on. When the chair frame 22 rotates 180° (i.e., the turn is completed), the second metal sensor 254 is located above the second metal sensor 252, and the indicator light of the second metal sensor 252 is always on, and the mechanism stops rotating. When the high-speed rail seat 2 needs to turn again, the second metal sensor 252 senses the position of the second metal sensor 254 as the starting position, and the first metal sensor 251 senses the position of the first metal sensor 253 as the end position, causing the chair frame 22 to rotate 180° in the opposite direction.
[0047] If it is necessary to rotate any one of the high-speed rail seats 2 individually, the following high-speed rail passenger compartment small gap seat rotation method can be used, including the following steps:
[0048] (a1) When any high-speed rail seat 2 needs to be rotated, the seat frames 22 of the high-speed rail seats 2 adjacent to this high-speed rail seat 2 are moved away from this high-speed rail seat 2 by a preset distance.
[0049] (a2) Rotate the seat frame 22 of the high-speed rail seat 2 that needs to be rotated 180°.
[0050] (a3) Move the chair frames 22 of the high-speed rail seats 2 adjacent to the high-speed rail seats 2 that need to be rotated so that they return to their original central positions.
[0051] The centralized control rotation system for small-gap seats in a high-speed rail passenger compartment of this embodiment also includes a control system (not shown in the figure). The control system connects the various rotating components 24 and the various sliding components 23. The control system can centrally control the various rotating components 24 and the various sliding components 23, thereby centrally controlling the movement and rotation of each high-speed rail seat 2. Therefore, when the high-speed rail seats 2 on either side of the passenger compartment 1 need to be turned, the following high-speed rail passenger compartment small-gap seat rotation method can be adopted, including the following steps:
[0052] (b1) The high-speed rail seats 2 on one side of the passenger compartment 1 are numbered 1, 2, 3, ..., n from front to back in order, where n is the total number of high-speed rail seats 2 on that side. In this embodiment, n=18.
[0053] (b2) The high-speed train seats 2 numbered 3k-2 (k is a positive integer) are recorded as the first group of seats 201, i.e., the high-speed train seats 2 numbered 1, 4, 7, 10, 13, and 16 in this embodiment. The high-speed train seats 2 numbered 3k-1 (k is a positive integer) are recorded as the second group of seats 202, i.e., the high-speed train seats 2 numbered 2, 5, 8, 11, 14, and 15 in this embodiment. The high-speed train seats 2 numbered 3k (k is a positive integer) are recorded as the third group of seats 203, i.e., the high-speed train seats 2 numbered 3, 6, 9, 12, 15, and 18 in this embodiment.
[0054] (b3) When all the high-speed rail seats 2 on this side need to be rotated, perform steps (b4), (b5) and (b6) in any order.
[0055] (b4) First, move the seat frame 22 of the first group of seats 201 forward a predetermined distance, and move the seat frame 22 of the third group of seats 203 backward a predetermined distance. Then, rotate the seat frame 22 of the second group of seats 202 180°. Finally, move the seat frames 22 of the first group of seats 201 and the third group of seats 203 back to their original central positions.
[0056] (b5) First, move the chair frame 22 of the second group of seats 202 forward a predetermined distance, and move the chair frame 22 of the first group of seats 201 backward a predetermined distance. Then, rotate the chair frame 22 of the third group of seats 203 180°. Finally, move the chair frame 22 of the second group of seats 202 and the chair frame 22 of the first group of seats 201 back to their original central positions.
[0057] (b6) First, move the seat frame 22 of the third group of seats 203 forward a predetermined distance, and move the seat frame 22 of the second group of seats 202 backward a predetermined distance. Then, rotate the seat frame 22 of the first group of seats 201 180°. Finally, move the seat frames 22 of the third group of seats 203 and the second group of seats 202 back to their original center positions.
[0058] After adopting the high-speed rail passenger compartment small gap seat centralized control rotation system and rotation method of this embodiment, the spacing between the high-speed rail seats 2 in the passenger compartment 1 can be appropriately reduced, so more high-speed rail seats 2 can be installed in the passenger compartment 1, thereby increasing the passenger capacity.
[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
