Description

Technical Field

[0001] This invention relates to the field of rail vehicle technology, and more particularly to a side beam structure, underframe, car body, and rail vehicle. Background Technology

[0002] In recent years, with the rapid development of my country's rail transit industry, in order to alleviate urban traffic pressure and improve environmental quality, a three-dimensional public transportation system combining ground, underground, and aerial components has been formed. This system represents the future development direction. In recent years, suspended monorail vehicles, as a new type of rail transit vehicle, have gradually emerged. In traditional suspended monorail vehicle design, the side beam, as one of the key components connecting the car body and the running rails, plays a crucial role in ensuring the stability of the entire vehicle. However, under current technological conditions, the design of the side beam often focuses on functionality while neglecting its impact on the overall appearance of the suspended monorail vehicle. Especially when viewed from the bottom of the vehicle, the lack of a good transition between the side beam and the underframe results in a poor external appearance. Summary of the Invention

[0003] This invention provides a side beam structure, underframe, car body, and rail vehicle for a rail vehicle, which addresses the shortcomings of existing suspended rail vehicles that focus on the functionality of the underframe, especially the connection stability between the side beams and the secondary floor, while neglecting the importance of the side beams and secondary floor as part of the appearance of the suspended rail vehicle and their contribution to improving the appearance of the suspended rail vehicle.

[0004] According to a first aspect of the present invention, a side beam structure for a rail vehicle includes: a side beam body; an overlapping portion disposed on the side of the side beam body facing the interior space of the rail vehicle and extending along the length direction of the rail vehicle; wherein the overlapping portion overlaps with a first floor of the rail vehicle, and the first floor and the outer surface of the side beam body form part of the appearance of the rail vehicle.

[0005] It should be noted that the side beam structure is one of the important components of a rail vehicle. The main structure of a rail vehicle includes the side beam structure, the lifting seat, and the crossbeam. The side beam structure provided by this invention includes the side beam body and an overlapping part provided near the bottom of the side beam body. The first floor overlaps with the overlapping part, and the first floor and the outer surface of the side beam body form the appearance of the bottom of the rail vehicle, making the exposed part of the bottom of the rail vehicle more aesthetically pleasing.

[0006] Understandably, the first floor is the secondary floor of the rail vehicle, that is, the exposed part of the first floor is the exposed part of the bottom of the rail vehicle.

[0007] Furthermore, after the first floor is connected to the side beam body through the lap joint, the first floor and the side beam body together constitute part of the appearance of the rail vehicle, which improves the appearance of the rail vehicle and solves the problem that the bottom of the existing rail vehicle is mainly structural and functional, resulting in poor bottom appearance.

[0008] It should also be noted that, in the bottom side of the side beam structure mentioned in this invention, the bottom is the side closest to the ground, while the top is the side furthest from the ground relative to the bottom. In addition, the length direction of the rail vehicle is the direction in which the rail vehicle extends along the track, the vertical direction is the direction perpendicular to the ground, and the width direction of the rail vehicle is the direction in which the rail vehicle extends perpendicular to the track.

[0009] According to one embodiment of the present invention, the overlapping portion is further overlapping with the second floor of the rail vehicle, the second floor being the passenger compartment floor of the rail vehicle.

[0010] Specifically, this embodiment provides an implementation of an overlapping part and a second floor. In addition to overlapping with the first floor, the overlapping part also overlaps with the second floor, so that the side beam body provides a connection position for the first floor and the second floor respectively through the setting of the overlapping part. The exterior of the first floor and the side beam body constitute part of the appearance of the rail vehicle, while the second floor constitutes the passenger compartment floor of the rail vehicle.

[0011] According to one embodiment of the present invention, the overlapping portion includes: a first overlapping plate disposed vertically on one side near the bottom of the side beam body; a second overlapping plate disposed vertically at a distance from the first overlapping plate, and an overlapping space for the first floor to overlap is formed between the first overlapping plate and the second overlapping plate; and a third overlapping plate disposed vertically at a distance from the second overlapping plate, and an overlapping space for the second floor to overlap is formed between the second overlapping plate and the third overlapping plate.

[0012] Specifically, this embodiment provides an implementation of an overlapping portion, which includes a first overlapping plate, a second overlapping plate, and a third overlapping plate spaced apart along the vertical direction. This provides an overlapping position for the first floor and the second floor, meeting the installation requirements of the first floor and the second floor. At the same time, the outer surface of the first floor constitutes the appearance of the rail vehicle, taking into account both installation and aesthetic requirements.

[0013] According to one embodiment of the present invention, a limiting step is provided on the side surface of the third overlapping plate facing away from the second overlapping plate, and the second floor overlaps with the second overlapping plate and the limiting step respectively.

[0014] Specifically, this embodiment provides an implementation of a third overlapping plate. The limiting steps set on the third overlapping plate can provide an overlapping position for the second floor and also limit the second floor. This allows the second floor to be positioned during installation on the base frame by the two limiting steps on the two side beams that are spaced apart, thus improving positioning accuracy and installation efficiency. This satisfies the requirement of efficiency while connecting the second floor with the side beams to form the passenger room floor.

[0015] According to one embodiment of the present invention, it further includes: a plug-in portion disposed on the mating surface between the side beam body and the side wall of the rail vehicle, for realizing a detachable plug-in mating between the side beam body and the side wall.

[0016] Specifically, this embodiment provides an implementation of a plug-in part. The plug-in part enables rapid connection and positioning between the side wall and the edge beam body, thereby providing positioning support for welding and improving the quality of welding.

[0017] According to one embodiment of the present invention, the plug-in portion includes: a first plug-in plate and a second plug-in plate spaced apart on the mating surface, wherein a space for plugging into the side wall is formed between the first plug-in plate and the second plug-in plate; wherein the first plug-in plate is provided with a plug-in buckle that mates with the side wall.

[0018] Specifically, this embodiment provides an implementation of a first plug-in plate and a second plug-in plate. The plug-in part includes a first plug-in plate and a second plug-in plate that are spaced apart. The first plug-in plate and the second plug-in plate are for the side wall to be inserted into. At the same time, the first plug-in plate is provided with a plug-in buckle that cooperates with the side wall, which facilitates the positioning between the side beam body and the side wall. While satisfying the positioning, it can also take into account the quality of subsequent welding.

[0019] According to one embodiment of the present invention, the overlapping portion is provided with a plurality of receiving slots at intervals along the length direction of the rail vehicle, and the receiving slots are provided on the side of the side beam body near the interior space of the rail vehicle for installing the lifting seat.

[0020] Specifically, this embodiment provides an implementation of a receiving groove, wherein the overlapping part is provided with multiple receiving grooves at intervals along the length direction of the rail vehicle, and a lifting seat connected to the side beam body is provided in the receiving groove, thereby providing a lifting position.

[0021] According to a second aspect of the present invention, a chassis structure for a rail vehicle includes the aforementioned side beam structure for a rail vehicle.

[0022] According to one embodiment of the present invention, it further includes: a plurality of lifting seats, wherein the plurality of lifting seats are spaced apart along the length direction of the rail vehicle on the side of the side beam body facing the interior space of the rail vehicle.

[0023] Specifically, this embodiment provides an implementation method for a lifting seat. Multiple lifting seats are spaced apart on the inner surface of the side beam body along the length direction of the rail vehicle. On the one hand, the lifting seats provide a lifting position for subsequent lifting operations, ensuring the smooth unfolding of the lifting operation. On the other hand, the lifting seats are set inside the side beam body, making the exposed surface of the rail vehicle more aesthetically pleasing and avoiding the problem of the exposed surface of the rail vehicle being abrupt and affecting the appearance caused by the exposed lifting seats.

[0024] According to one embodiment of the present invention, the lifting seat includes: a top plate, a base, a back plate, stiffening plates, and two side plates; the top plate, the base, and the two side plates surround to form a frame structure; the back plate is provided at one open side of the frame structure, and the other open side of the frame structure is connected to the side beam body; the stiffening plates are located within the frame structure and are respectively connected to the back plate and the side beam body.

[0025] Specifically, this embodiment provides an implementation of a lifting seat structure. The lifting seat is configured to include a top plate, a base, a back plate, stiffening ribs, and two side plates, thus forming a frame structure that improves the load-bearing capacity of the lifting seat. At the same time, the stiffening ribs enable the frame structure of the lifting seat to obtain greater strength, and thus have a greater load-bearing capacity in the lifting operation of rail vehicles.

[0026] According to one embodiment of the present invention, at least a portion of the base protrudes from the contact surface between the frame structure and the side beam body, and the protruding portion of the base overlaps with the side beam body.

[0027] Specifically, this embodiment provides an implementation of a base, which is configured to partially protrude from the contact surface between the frame structure and the side beam body, that is, the contact surface between the lifting seat and the inner side of the side beam body, so that the protruding part of the base can overlap with the side beam body, so that the lifting seat and the side beam body have a vertical engagement position in addition to the inner contact position, so that the lifting seat can obtain strength supplement through the side beam body during the lifting operation of the rail vehicle.

[0028] According to one embodiment of the present invention, the welding sequence of the lifting seat and the side beam body is as follows: the two side plates are welded and positioned to the side beam body; the stiffening plate is disposed between the two side plates and welded and positioned to the side beam body; the back plate is welded and connected to the two side plates and the stiffening plate respectively; the top plate is welded and connected to the two side plates, the stiffening plate and the back plate respectively; the base is welded and connected to the two side plates, the stiffening plate, the back plate and the top plate respectively, and the base portion protrudes from the welding surface between the two side plates and the side beam body; wherein, the protruding portion of the base is welded and connected to the side beam body.

[0029] Specifically, this embodiment provides an implementation method for the welding sequence of the lifting platform and the side beam body. The setting of the welding sequence of the lifting platform and the side beam body satisfies the welding and installation of the lifting platform and the side beam body during the construction process, as well as how the side beam body forms a frame structure and strengthens the structural strength. It satisfies the connection between the lifting platform and the side beam body of the frame structure, and takes into account both installation strength and aesthetic requirements.

[0030] According to one embodiment of the present invention, it further includes: a crossbeam, the crossbeam being welded to the side of the back plate facing away from the side beam body.

[0031] Specifically, this embodiment provides an implementation of a crossbeam. The crossbeam abuts against the back plate of the lifting seat and is welded to form an integral structure. This allows the lifting seat to distribute the force when under stress during the lifting operation of the rail vehicle through the side beam body and the crossbeam. Furthermore, since the crossbeam abuts against two opposing lifting seats, the strength of the lifting seat can be guaranteed, thus reinforcing the lifting seat.

[0032] According to a third aspect of the present invention, a vehicle body includes the side beam structure of the above-described rail vehicle or the underframe structure of the above-described rail vehicle.

[0033] According to one embodiment of the present invention, a first floor and a second floor are respectively connected to an overlapping portion; the first floor is configured as the exterior structure of the rail vehicle; the second floor is configured as the passenger compartment floor of the rail vehicle; wherein a receiving cavity is formed between the first floor and the second floor, the receiving cavity being at least used to receive cables.

In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0053] The present invention will now be described in detail with reference to specific embodiments.

[0054] In some specific embodiments of the present invention, such as Figures 1 to 6 As shown, this solution provides a side beam structure for a rail vehicle, including: a side beam body 10; an overlapping portion 20, which is disposed on the side of the side beam body 10 facing the internal space of the rail vehicle and extends along the length direction of the rail vehicle; wherein, the overlapping portion 20 overlaps with the first floor 30 of the rail vehicle, and the first floor 30 and the outer surface of the side beam body 10 form part of the appearance of the rail vehicle.

[0055] It should be noted that the side beam structure is one of the important components of the rail vehicle. The main structure of the rail vehicle includes the side beam structure, the lifting seat 50, the crossbeam 60, etc. The side beam structure provided by the present invention includes the side beam body 10 and the overlapping part 20 provided near the bottom of the side beam body 10. The first floor 30 overlaps with the overlapping part 20, and the first floor 30 and the outer surface of the side beam body 10 form the appearance of the bottom of the rail vehicle, making the exposed part of the bottom of the rail vehicle more aesthetically pleasing.

[0056] Understandably, the first floor 30 is the secondary floor of the rail vehicle, that is, the exposed part of the first floor 30 is the exposed part of the bottom of the rail vehicle.

[0057] Furthermore, after the first floor 30 is connected to the side beam body 10 through the overlap part 20, the first floor 30 and the side beam body 10 together constitute part of the appearance of the rail vehicle, which improves the aesthetics of the rail vehicle and solves the problem that the bottom of the existing rail vehicle is mainly structural and functional, resulting in poor bottom appearance.

[0058] In a possible embodiment, the first floor 30 and the overlapping portion 20 are positioned by overlapping and then welded together.

[0059] In a possible embodiment, the first floor 30 is the secondary floor of the rail vehicle.

[0060] In a possible embodiment, the rail vehicle is a suspended rail vehicle, also known as an aerial rail or sky train. The top of the suspended rail vehicle is equipped with structures such as bogies, while the bottom of the suspended rail vehicle is an exposed part.

[0061] In a possible embodiment, the rail vehicle provided by the present invention is a suspended monorail vehicle.

[0062] It should also be noted that, in the bottom side of the side beam structure mentioned in this invention, the bottom is the side closest to the ground, while the top is the side furthest from the ground relative to the bottom. In addition, the length direction of the rail vehicle is the direction in which the rail vehicle extends along the track, the vertical direction is the direction perpendicular to the ground, and the width direction of the rail vehicle is the direction in which the rail vehicle extends perpendicular to the track.

[0063] In some possible embodiments of the present invention, the overlapping portion 20 is also overlapped with the second floor 40 of the rail vehicle, which is the passenger compartment floor of the rail vehicle.

[0064] Specifically, this embodiment provides an implementation of an overlap portion 20 and a second floor 40. In addition to overlapping with the first floor 30, the overlap portion 20 also overlaps with the second floor 40, so that the side beam body 10 provides connection positions for the first floor 30 and the second floor 40 respectively through the arrangement of the overlap portion 20. The first floor 30 and the exterior of the side beam body 10 constitute part of the appearance of the rail vehicle, while the second floor 40 constitutes the passenger compartment floor of the rail vehicle.

[0065] In a possible embodiment, the second floor 40 is an aluminum floor, which is positioned with the overlapping part 20 by overlapping and then connected by welding.

[0066] In a possible embodiment, the second floor 40 is a honeycomb floor, which is positioned with the overlapping part 20 by overlapping and then connected by welding.

[0067] In some possible embodiments of the present invention, the overlapping portion 20 includes: a first overlapping plate 21, which is disposed vertically on one side near the bottom of the side beam body 10; a second overlapping plate 22, which is disposed vertically at a distance from the first overlapping plate 21, and an overlapping space for the first floor 30 to overlap is formed between the first overlapping plate 21 and the second overlapping plate 22; and a third overlapping plate 23, which is disposed vertically at a distance from the second overlapping plate 22, and an overlapping space for the second floor 40 to overlap is formed between the second overlapping plate 22 and the third overlapping plate 23.

[0068] Specifically, this embodiment provides an implementation of the overlapping part 20, which includes a first overlapping plate 21, a second overlapping plate 22 and a third overlapping plate 23 arranged at intervals along the vertical direction. This provides an overlapping position for the first floor 30 and the second floor 40, meets the installation requirements of the first floor 30 and the second floor 40, and at the same time, the outer surface of the first floor 30 constitutes the appearance of the rail vehicle, taking into account both installation and aesthetic requirements.

[0069] In some possible embodiments of the present invention, a limiting step 25 is provided on the side surface of the third overlapping plate 23 facing away from the second overlapping plate 22, and the second floor 40 overlaps with the second overlapping plate 22 and the limiting step 25 respectively.

[0070] Specifically, this embodiment provides an implementation of the third overlapping plate 23. The limiting steps 25 provided on the third overlapping plate 23 can provide an overlapping position for the second floor 40 and also limit the second floor 40. During the installation of the second floor 40 to the base frame, it can be positioned by the two corresponding limiting steps 25 on the two spaced side beam bodies 10, which provides positioning accuracy and improves installation efficiency. While meeting the requirement of connecting the second floor 40 and the side beam bodies 10 to form the passenger room floor, it also takes into account the need for efficiency.

[0071] In a possible embodiment, after the second floor 40 overlaps with the limiting step 25, it is welded to the third overlapping plate 23 and the limiting step 25 to ensure the reliability of the connection between the second floor 40 and the side beam body 10. At the same time, the setting of the limiting step 25 can also improve the welding quality between the second floor 40 and the side beam body 10.

[0072] In some possible embodiments of the present invention, it further includes: a plug-in part, disposed on the mating surface between the side beam body 10 and the side wall of the rail vehicle, for realizing a detachable plug-in mating between the side beam body 10 and the side wall.

[0073] Specifically, this embodiment provides an implementation of a plug-in part. The plug-in part enables rapid connection and positioning between the side wall and the edge beam body 10, thereby providing positioning support for welding and improving the quality of welding.

[0074] In some possible embodiments of the present invention, the plug-in portion includes: a first plug-in plate 11 and a second plug-in plate 12 spaced apart on the mating surface, with a space for plugging into the side wall formed between the first plug-in plate 11 and the second plug-in plate 12; wherein the first plug-in plate 11 is provided with a plug-in buckle 13 that mates with the side wall.

[0075] Specifically, this embodiment provides an implementation of a first plug-in plate 11 and a second plug-in plate 12. The plug-in part includes a first plug-in plate 11 and a second plug-in plate 12 arranged at intervals. The first plug-in plate 11 and the second plug-in plate 12 are for insertion into the side wall. At the same time, a plug-in buckle 13 that cooperates with the side wall is provided on the first plug-in plate 11, which facilitates the positioning between the side beam body 10 and the side wall. While satisfying the positioning, it can also take into account the quality of subsequent welding.

[0076] In some possible embodiments of the present invention, the overlapping part 20 is provided with a plurality of receiving slots 24 at intervals along the length direction of the rail vehicle. The receiving slots 24 are provided on the side of the side beam body 10 near the interior space of the rail vehicle and are used to install the lifting seat 50.

[0077] Specifically, this embodiment provides an implementation of the receiving groove 24. The overlapping part 20 is provided with a plurality of receiving grooves 24 at intervals along the length direction of the rail vehicle. A lifting seat 50 connected to the side beam body 10 is provided in the receiving groove 24, thereby providing the lifting position.

[0078] Furthermore, the lifting seat 50 is located on the inner side of the side beam body 10, which improves the aesthetic appearance of the rail vehicle and solves the problem that the existing lifting seat 50 is located at the bottom of the side beam and exposed to the outside of the rail vehicle, affecting the appearance of the bottom of the rail vehicle.

[0079] Furthermore, the lifting seat 50 is located on the inner side of the side beam body 10. While meeting the lifting requirements, the lifting seat 50 and the first floor 30 together form the bottom appearance of the rail vehicle, making the bottom appearance of the rail vehicle more complete and beautiful, taking into account both installation and aesthetic requirements.

[0080] In a possible embodiment, the rail vehicle is a suspended rail vehicle. The rail vehicle provides power through structures such as bogies mounted on the top, while the bottom of the rail vehicle is completely exposed to the outside. In this invention, the first floor 30 and the side beam body 10 together constitute part of the appearance of the bottom of the rail vehicle, and the lifting seat 50 is set on the inner side of the side beam body 10. The lifting seat 50, the first floor 30, and the side beam body 10 together constitute part of the appearance of the bottom of the rail vehicle, which enhances the aesthetics of the exposed bottom of the rail vehicle.

[0081] In a possible embodiment, the working surface of the lifting seat 50 is coplanar with the outer surface of the first floor 30, and the working surface of the lifting seat 50 is the force-applying surface during the lifting operation.

[0082] In a possible embodiment, the lifting seat 50 is a frame structure consisting of a top plate 51, a base 52, a back plate 53, a stiffening plate 54 and two side plates 55. The working surface of the lifting seat 50 is the plane where the base 52 is located. The outer surface of the base 52 is coplanar with the outer surface of the first floor 30. It can be understood that the outer surface is the other side surface relative to the interior of the rail vehicle, that is, the exposed side surface of the rail vehicle.

[0083] In some specific embodiments of the present invention, such as Figures 1 to 6 As shown, this solution provides a chassis structure for a rail vehicle, including the aforementioned side beam structure of the rail vehicle.

[0084] In some possible embodiments of the present invention, it further includes: a plurality of lifting seats 50, which are spaced apart along the length direction of the rail vehicle on the side of the side beam body 10 facing the interior space of the rail vehicle.

[0085] Specifically, this embodiment provides an implementation of a lifting seat 50. Multiple lifting seats 50 are spaced apart on the inner surface of the side beam body 10 along the length direction of the rail vehicle. On the one hand, the lifting seats 50 provide a lifting position for subsequent lifting operations, ensuring the smooth unfolding of the lifting operations. On the other hand, the lifting seats 50 are set inside the side beam body 10, making the exposed surface of the rail vehicle more aesthetically pleasing and avoiding the problem of the exposed surface of the rail vehicle being abrupt and affecting the appearance caused by the exposed lifting seats 50.

[0086] In a possible embodiment, the rail vehicle is a suspended monorail vehicle, which is suspended in the air and has its bottom exposed. The lifting seat 50 is set on the inner side of the side beam body 10 and together with the first floor 30, it forms the bottom appearance of the rail vehicle, which solves the problem of exposed parts in the exposed part of the rail vehicle and improves the aesthetics of the exposed part of the rail vehicle.

[0087] In some possible embodiments of the present invention, the lifting seat 50 includes: a top plate 51, a base 52, a back plate 53, a stiffening plate 54, and two side plates 55; the top plate 51, the base 52, and the two side plates 55 surround to form a frame structure; a back plate 53 is provided at one open side of the frame structure, and the other open side of the frame structure is connected to the side beam body 10; the stiffening plate 54 is inside the frame structure and is connected to the back plate 53 and the side beam body 10 respectively.

[0088] Specifically, this embodiment provides an implementation of the structure of the lifting seat 50. The lifting seat 50 is configured to include a top plate 51, a base 52, a back plate 53, stiffening plates 54, and two side plates 55, so that the lifting seat 50 forms a frame structure, which improves the load-bearing capacity of the lifting seat 50. At the same time, the stiffening plates 54 enable the frame structure of the lifting seat 50 to obtain greater strength, and thus have a greater load-bearing capacity in the lifting operation of rail vehicles.

[0089] In some possible embodiments of the present invention, at least a portion of the base 52 protrudes from the contact surface between the frame structure and the side beam body 10, and the protruding portion of the base 52 overlaps with the side beam body 10.

[0090] Specifically, this embodiment provides an implementation of a base 52, which is configured to partially protrude from the contact surface between the frame structure and the side beam body 10, that is, the contact surface between the lifting seat 50 and the inner side of the side beam body 10, so that the protruding part of the base 52 can overlap with the side beam body 10, so that the lifting seat 50 and the side beam body 10 have a vertical engagement position in addition to the inner contact position, so that the lifting seat 50 can obtain strength supplement through the side beam body 10 during the lifting operation of the rail vehicle.

[0091] It should be noted that the part of the base 52 that protrudes from the frame structure formed by the lifting seat 50 can play a role in supplementing strength during the lifting operation of rail vehicles. This solves the problem that in the existing lifting process, the main stress position is the welded surface between the lifting seat 50 and the side beam body 10, and long-term use results in insufficient strength at the welded position, leading to weld breakage.

[0092] Furthermore, the lifting seat 50 forms a mating relationship with the side beam body 10 through the protruding part of the base 52. This allows the lifting seat 50 to bear the force at the welded position with the side beam body 10 during the lifting operation of the rail vehicle. At the same time, the force can also be distributed to the side beam body 10 through the vertical overlap relationship between the base 52 and the side beam body 10. This optimizes the stress environment of the lifting seat 50, strengthens the strength and service life of the lifting seat 50, and improves the safety during the lifting operation.

[0093] In a possible embodiment, the surface of the base 52 facing away from the side beam body 10 is provided with a diamond pattern structure, which can prevent slippage during the lifting operation.

[0094] In some possible embodiments of the present invention, the welding sequence of the lifting seat 50 and the side beam body 10 is as follows: the two side plates 55 are welded and positioned to the side beam body 10; the stiffening plate 54 is disposed between the two side plates 55 and welded and positioned to the side beam body 10; the back plate 53 is welded and connected to the two side plates 55 and the stiffening plate 54 respectively; the top plate 51 is welded and connected to the two side plates 55, the stiffening plate 54 and the back plate 53 respectively; the base 52 is welded and connected to the two side plates 55, the stiffening plate 54, the back plate 53 and the top plate 51 respectively, and the base 52 partially protrudes from the welding surface of the two side plates 55 and the side beam body 10; wherein, the protruding part of the base 52 is welded and connected to the side beam body 10.

[0095] Specifically, this embodiment provides an implementation method for the welding sequence of the lifting platform 50 and the side beam body 10. The setting of the welding sequence of the lifting platform 50 and the side beam body 10 satisfies the welding and installation of the lifting platform 50 and the side beam body 10 during the construction process, as well as how the side beam body 10 forms a frame structure and strengthens the structural strength. It satisfies the connection between the lifting platform 50 and the side beam body 10 of the frame structure, and takes into account both installation strength and aesthetic requirements.

[0096] In some possible embodiments of the present invention, it further includes: a crossbeam 60, which is welded to the back plate 53 on the side facing away from the side beam body 10.

[0097] Specifically, this embodiment provides an implementation of a crossbeam 60. The crossbeam 60 abuts against the back plate 53 of the lifting seat 50 and is welded to form an integral structure. This allows the lifting seat 50 to distribute the force under stress through the side beam body 10 and the crossbeam 60 during the lifting operation of the rail vehicle. Furthermore, since the crossbeam 60 abuts against the two opposing lifting seats 50, the strength of the lifting seat 50 is also guaranteed, thus reinforcing the lifting seat 50.

[0098] In some specific embodiments of the present invention, such as Figures 1 to 6 As shown, this solution provides a vehicle body, including the side beam structure of the aforementioned rail vehicle, or the underframe structure of the aforementioned rail vehicle.

[0100] Specifically, this embodiment provides an implementation of a first floor 30 and a second floor 40. The first floor 30 and the second floor 40 are connected to the side beam body 10 through overlapping portions 20. The first floor 30 and the side beam body 10 together constitute part of the appearance of the rail vehicle, improving the integrity and aesthetics of the exposed parts of the rail vehicle. At the same time, a cable-accommodating cavity is formed between the first floor 30 and the second floor 40, improving the utilization rate of the rail vehicle space and avoiding problems such as cables occupying side walls and roofs. This greatly ensures the space of the rail vehicle's passenger compartment, improves the passenger capacity of the rail vehicle, and enhances the user's riding experience.
