[0083] In some possible implementations 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 the side beam body 10 .

[0084] Specifically, this embodiment provides an implementation of a base 52, in which the base 52 is configured to partially protrude and abut against the frame structure and the side beam body 10, that is, the abutment surface between the vehicle lifting seat 50 and the inner side of the side beam body 10, so that the protruding portion of the base 52 can be overlapped with the side beam body 10, so that in addition to the inner abutment position between the vehicle lifting seat 50 and the side beam body 10, there is also a vertical matching position, so that when the rail vehicle is lifting, the vehicle lifting seat 50 can obtain strength supplementation through the side beam body 10.

[0085] It should be noted that the part of the base 52 protruding from the frame structure formed by the car lifting seat 50 can play a role in supplementing strength during the rail vehicle lifting operation, and solves the problem that in the existing car lifting process, the main force-bearing position is the welding surface between the car lifting seat 50 and the side beam body 10, and the welding position has insufficient strength after long-term use, resulting in fracture of the weld.

[0086] Furthermore, a mating relationship is formed between the vehicle lifting seat 50 and the side beam body 10 through the protruding part of the base 52, so that during the rail vehicle lifting operation, while the welding position of the vehicle lifting seat 50 and the side beam body 10 is subjected to force, part of the force can be decomposed to the side beam body 10 through the overlapping relationship between the base 52 and the side beam body 10 in the vertical direction, thereby optimizing the force environment of the vehicle lifting seat 50, enhancing the strength and service life of the vehicle lifting seat 50, and improving the safety of the vehicle lifting operation.

[0087] In a possible embodiment, a diamond pattern structure is provided on a surface of the base 52 facing away from the side beam body 10 to prevent slipping during the vehicle lifting operation.

[0088] In some possible implementations of the present invention, the welding sequence of the vehicle lift seat 50 and the side beam body 10 is as follows: the two side panels 55 are welded and positioned with the side beam body 10; the rib plate 54 is arranged between the two side panels 55 and welded and positioned with the side beam body 10; the back panel 53 is welded and connected with the two side panels 55 and the rib plate 54 respectively; the top panel 51 is welded and connected with the two side panels 55, the rib plate 54 and the back panel 53 respectively; the base 52 is welded and connected with the two side panels 55, the rib plate 54, the back panel 53 and the top panel 51 respectively, and a portion of the base 52 protrudes from the welding surface of the two side panels 55 and the side beam body 10; wherein, the protruding portion of the base 52 is welded and connected with the side beam body 10.

[0089] Specifically, this embodiment provides an implementation method for the welding sequence of the vehicle lift seat 50 and the side beam body 10. The setting of the welding sequence of the vehicle lift seat 50 and the side beam body 10 satisfies the welding and installation of the vehicle lift seat 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 reinforces the structural strength, which satisfies the connection between the vehicle lift seat 50 and the side beam body 10 of the frame structure, and takes into account the installation strength and aesthetic requirements.

[0090] In some possible implementations of the present invention, the present invention further includes: a cross beam 60 , and the cross beam 60 is welded to a side of the back plate 53 facing away from the side beam body 10 .

[0091] Specifically, this embodiment provides an implementation method of a crossbeam 60, in which the crossbeam 60 is abutted against the back plate 53 of the vehicle lifting seat 50 and welded to form an integrated structure, so that during the rail vehicle lifting operation, the vehicle lifting seat 50 can disperse the force through the side beam body 10 and the crossbeam 60 when subjected to force, and because the crossbeam 60 respectively abuts against the two opposite vehicle lifting seats 50, the strength of the vehicle lifting seat 50 can also be guaranteed, thereby achieving reinforcement of the vehicle lifting seat 50.

[0093] In some possible embodiments of the present invention, a first floor 30 and a second floor 40 are respectively connected to the overlapping portion 20; the first floor 30 is set as the appearance structure of the rail vehicle; the second floor 40 is set as the passenger compartment floor of the rail vehicle; wherein a accommodating cavity is formed between the first floor 30 and the second floor 40, and the accommodating cavity is at least used to accommodate cables.

[0094] Specifically, this embodiment provides an implementation method of a first floor 30 and a second floor 40, wherein the first floor 30 and the second floor 40 are respectively connected to the side beam body 10 through the overlap portion 20, and the first floor 30 and the side beam body 10 together constitute part of the appearance of the rail vehicle, thereby improving the integrity and aesthetics of the exposed part of the rail vehicle. At the same time, a cable accommodating cavity is formed between the first floor 30 and the second floor 40, thereby improving the utilization rate of the space of the rail vehicle, avoiding the existence of problems such as cables occupying side walls and roofs, greatly ensuring the space of the passenger compartment of the rail vehicle, improving the passenger carrying capacity of the rail vehicle, and the user's riding experience.
