[0025] The following is a further detailed description of the specific implementation methods of the present invention by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0026] like Figure 1 and Figure 2 As shown, the openable and closable rail vehicle seat structure includes a floor 1 and side walls 2. The seat structure includes a seat frame 3 and a seat panel 4. The seat panel 4 is arranged on the seat frame 3. The bottom of the seat frame 3 is connected to the floor 1, and the side of the seat frame 3 is connected to the side wall 2. A storage space 5 is provided inside the seat frame 3.

[0027] In this structure, the seat frame 3 is connected to both the floor 1 and the side walls 2. Compared to the existing open structure with triangular brackets mounted on the side walls 2, this provides more even force distribution, making the seat frame 3 and seat panel 4 less susceptible to damage, resulting in greater stability and a longer service life for the seat structure. Furthermore, the edges of the seat frame 3 contact the floor 1 and side walls 2, creating a storage cavity within the seat frame 3 that can also serve as equipment storage space 5. This fully utilizes the space in the floor 1, meeting the storage needs of passengers and increasing vehicle space utilization.

[0028] like Figure 6 and Figure 7As shown, the seat panel 4 includes a top panel 9, with a reinforcing beam 10 provided on the inner side thereof. A first support 6 is provided on the reinforcing beam 10. A second support 7 is provided on the inner side of the top of the seat frame 3. A connecting rod 8 connects the first support 6 and the second support 7. The ends of the connecting rod 8 are hinged to the first support 6 and the second support 7, respectively. A tongue lock 11 is connected to the bottom of the seat panel 4 and the seat frame 3. The reinforcing beam 10 provides a mounting position for the first support 6 when reinforcing the structure of the seat panel 4. The seat frame 3 is a fixed structure. The arrangement of the connecting rod 8 enables the hinged connection between the top of the seat panel 4 and the seat frame 3, thereby enabling the rotation of the seat panel 4, avoiding the adverse effects of a rigid connection on the structural performance of the seat panel 4. When storing items, the user only needs to release the lock between the bottom of the seat panel 4 and the seat frame 3 and rotate the seat panel 4 to a certain angle to store items. This eliminates part of the operation process and improves the convenience of storage. The tongue lock 11 adopts the existing tongue lock mechanism. The key insertion end of the tongue lock 11 is located in the middle of the front of the seat frame 3. Steel wire ropes 12 are connected on both sides of the tongue lock 11. The ends of the steel wire ropes 12 are connected to lock buckles 13. Two lock buckle rings 14 corresponding to the lock buckles 13 are provided at the bottom of the seat panel 4. The working principle of the tongue lock 11 to open and close the storage space 5 is to rotate the tongue lock 11 with a key to pull the steel wire rope 12, thereby controlling the lock buckle 13 to release or lock the lock buckle ring 14, thereby achieving the effect of releasing or fixing the seat panel 4, and easy operation.

[0029] like Figure 2 and Figure 5 As shown, storage space 5 is formed by floor 1, side walls 2, and seat frame 3. Seat panel 4 is located above storage space 5. Floor 1, side walls 2, seat frame 3, and seat panel 4 form a closed structure. This structure creates a closed structure for storage space 5. The installation of seat panel 4 provides a closed and shielded storage space 5, preventing equipment or items stored in storage space 5 from being exposed, thus maintaining the neatness and aesthetics of the seat.

[0030] like Figure 5 As shown, the seat frame 3 is provided with flanges 15 on both the sides and bottom. The flanges 15 are integral with the seat frame 3 and located within the seat frame 3. Connecting bolts 16 are provided on the flanges 15. The flanges 15 are planar and located within the seat frame 3. They are integrally formed with the seat frame 3 and do not occupy the storage space within the seat frame 3. The flanges 15 provide mounting areas for the connecting bolts 16. The provision of the flanges 15 increases the contact area between the seat frame 3 and the floor 1 and side walls 2. The presence of multiple connecting bolts 16 improves the stability of the seat frame 3 installation. Furthermore, the compressive force of the connecting bolts 16 does not directly affect the structure of the seat frame 3, facilitating force dispersion.

[0031] like Figure 8As shown, the seat panel 4 is fitted with a reinforcement panel 17 at the bottom, with a reinforcement layer 18 located between them. Both the seat panel 4 and reinforcement panel 17 are constructed from fiberglass reinforced plastic (FRP), while reinforcement layer 18 is constructed from PET. The seat panel 4 is primarily constructed from 4mm FRP, while reinforcement panel 17 is 3mm thick and reinforcement layer 18 is 15mm thick. This reinforces weak areas of the seat panel 4, creating a 22mm thick sandwich structure. This improves the deformation resistance of the load-bearing areas of the seat panel 4 and enhances its durability. The seat panel 4's primary structure is constructed from 4mm fiberglass, with PET sandwiched between sections. Simulations and physical testing confirm that its strength and functionality meet design and use requirements.

[0032] like Figure 5 As shown, a mounting plate 19 is provided on the inner side of the seat frame 3, and a universal bracket 20 is provided on the mounting plate 19. A plurality of universal brackets 20 are provided to provide support for the seat panel 4, thereby improving the load-bearing reliability of the seat panel 4.

[0033] like Figure 5 As shown, the first support 6 and the second support 7 are arranged in pairs. The above structure forms a two-point connection support for the top of the seat panel 4, which is beneficial to prevent the seat panel 4 from tilting and improve the stability of the seat panel 4 when storing items.

[0034] like Figure 2 As shown, the seat panel 4 is tilted, which is conducive to making the passengers sit at a suitable angle, helps to relieve fatigue, and reduces the space occupied in the car.

[0035] The seat frame 3 and the seat panel 4 are connected by a triangular tongue lock 11 driving two lock buckles 13. When the seat needs to be opened, a special triangular key is used to turn the tongue lock 11, driving the wire rope 12 to unlock the lock tongues on both sides to open the seat panel 4. The storage space 5 is opened, and maintenance and operation personnel can store / take items or inspect the equipment.

[0036] The retractable rail vehicle seat structure solves the current problem of low space utilization of the floor 1 in the seat frame 3 area of ​​APM vehicles by providing a storage space 5 inside the seat frame 3 and improving the connection between the seat frame 3 and the seat panel 4, thereby providing maintenance and operating personnel with the necessary storage space 5. The fixing structure of the seat frame 3 and the seat panel 4 is reasonably designed, which improves the stability of the seat structure, ensures reliable load-bearing function, and extends the service life.

[0037] The above description of the present invention is provided as an example, in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described method. Any non-substantial improvements made using the method concepts and technical solutions of the present invention, or any application of the above-described concepts and technical solutions of the present invention to other situations without modification, are all within the scope of protection of the present invention.
