Description

Integrated side suspension module for locomotives

[0001] This application claims priority to Chinese Patent Application No. 202411797658.X, filed with the Chinese Patent Office on December 9, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of locomotive technology, for example to an integrated side suspension module for locomotives, such as an outer-corridor locomotive that is integrated from multiple modules, can be manufactured in different scenarios, and is cost-effective. Background Technology

[0003] In some locomotives (such as shunting locomotives), the two side areas in the lateral direction of the locomotive have various components such as corridor floors, handrails, side panels, pipes, and wiring, forming the locomotive's external corridor structure. To facilitate the installation of these components, in some related art solutions, the side areas also have side beams welded to the locomotive underframe, on which mounting seats for various components are welded to achieve the installation of multiple components. For example, Figure 1 shows a schematic diagram of a side beam in related art. As shown in Figure 1, the side beam includes multiple L-shaped beams 20 and multiple C-shaped grooves 30 welded to both sides of the locomotive underframe 10. The upper side of the L-shaped beams 20 is spliced ​​and welded to the C-shaped grooves 30 to form a support.

[0004] In the relevant technical solutions, installation requires first welding the side beams to the locomotive underframe, then welding the mounting bases for each component to the side beams, and finally installing each component into its corresponding mounting base. These production processes must all be completed on the main production line of the car body, resulting in a long production cycle. Furthermore, the large number of mounting bases for the components makes them prone to interference and confusion in assembly sequence during installation, impacting production efficiency.

[0071] It should be noted that all uses of "first" and "second" in the embodiments of this application are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this application. Subsequent embodiments will not explain this in detail.

[0072] As mentioned in the background section, the installation methods for multiple components in the side areas of locomotives using related technologies have several shortcomings. For example, side beams are directly welded to the underframe, resulting in various forms and numbers, requiring positioning fixtures for limiting their position, and making post-weld adjustments almost impossible, leading to a low tolerance for error. The welded side beam structure has a single function; the installation of side decorative panels, pipes, cable trays, corridor floors, and other components requires separate installation structures, which are then welded to the side beam. This intertwining of multiple installation structures results in a high installation error rate and low production efficiency. Since the installation structures for multiple components are all welded to the side beam, the inherent errors of each component, combined with welding errors, can cause interference during component installation, even requiring rework and repositioning. The large number of welding mounting bases for components, the high requirements for relative positional dimensions, the large number of positioning fixtures, and the difficulty in ensuring dimensional accuracy are all factors. Furthermore, the separate installation of handrails, side decorative panels, pipes, cable trays, corridor floors, and other components on the main assembly line results in excessive occupancy of the main locomotive production line, hindering the reduction of locomotive production cycles. When multiple disciplines perform simultaneous, overlapping installations at the same final assembly station, it can easily lead to confusion in the assembly sequence, resulting in errors or even rework. Piping and cable trays installed on the upper side of the side beam result in low space utilization in the vertical direction. This application proposes one or more embodiments, as described below, that provide an integrated side suspension module for locomotives. This module decouples the locomotive underframe from the side beam area and multiple systems installed in the side beam area, enabling multi-scenario manufacturing. This addresses the problem of excessive occupation of the main production line and low production efficiency due to the installation of multiple components in the locomotive side area; it also solves the problem of mutual interference during installation.

[0073] Referring to Figures 2 and 3, this application proposes an integrated side suspension module 100 for a locomotive, including: a support unit 110 and handrail assembly 120, side trim panel 130, corridor floor 140, pipes 150, and wiring 152 integrated into the support unit 110. The integrated side suspension module 100 defines the longitudinal, lateral, and vertical directions, corresponding to the length, width, and height directions of the locomotive, respectively. The integrated side suspension module 100 is connected to the locomotive underframe and suspended on opposite sides in the lateral direction, respectively. The side of the integrated side suspension module 100 connected to the underframe is designated as the inner lateral side, and the side of the integrated side suspension module 100 away from the underframe is designated as the outer lateral side.

[0074] Referring to Figure 4, the support unit 110 includes multiple brackets 112 spaced longitudinally and multiple connecting beams 114 spaced longitudinally. Each connecting beam 114 is detachably connected between adjacent brackets 112. The multiple brackets 112 and multiple connecting beams 114 combine to form a longitudinally extending frame structure, configured to support various components in various locomotive side areas. The support unit 110 itself constitutes a modular structure that can be independently manufactured and assembled. The support unit 110 uses brackets 112 and connecting beams 114 as basic building blocks, has a high reusability, and its longitudinal length can be adjusted by changing the number of brackets 112 and connecting beams 114 to meet the individual needs of different vehicle lengths.

[0075] The bracket 112 and the connecting beam 114 can be detachably connected, allowing for adjustments to the number of units by disassembly and reassembly, thereby adjusting the longitudinal length of the support unit 110. In some embodiments, referring to FIG7, the bracket 112 has connecting beam mounting seats 1125 on both longitudinal sides. The connecting beam mounting seats 1125 can support the longitudinal side areas of the connecting beam 114 and are provided with mounting holes. The bracket 112 and the connecting beam 114 are detachably connected through the cooperation of the mounting holes and fasteners.

[0076] Figure 5 shows a functional partition diagram of the support unit 110 according to an embodiment of this application. Referring to Figures 2 and 5, the inner lateral side of the bracket 112 forms a mounting area a for the support unit 110 itself and the vehicle chassis frame. This mounting area has a support unit mounting member configured to mount the support unit 110 to the locomotive chassis frame 10 (Figure 6). The outer lateral side of the bracket 112 forms a handrail mounting area d, which has a handrail mounting member such that the handrail assembly 120 is fixed to the outer lateral side of the bracket 112. The outer lateral side of the connecting beam 114 forms a side panel mounting area e, which has a structure configured for side panel mounting such that the side panel 130 is fixed to the outer lateral side of the connecting beam 114. The upper side of the connecting beam 114 forms a corridor floor mounting area c, which has a corridor floor mounting member such that the corridor floor 140 is fixed to the upper side of the connecting beam 114. The interior of the support unit 110 forms a brake line and electrical wiring mounting area b, which has a receiving space configured to accommodate the pipe 150 and the line 152. The support unit 110 also forms an extension equipment mounting area g, which has additional accommodating space spaced laterally from the accommodating space. The lower part of the bracket 112 also forms a charger socket mounting area f, which has a charger socket mounting component, allowing the charger socket to be mounted on the lower part of the bracket 112. The support unit 110 also has an operating area h located between the connecting beam 114 and the base frame, which provides the necessary operating space for installing the integrated side suspension module 100. Each functional area of ​​the support unit 110 performs its specific function, with a reasonable layout that cleverly and fully utilizes the multiple areas and spaces of the support unit 110.

[0077] In the embodiments of this application, the support unit 110 integrates various installation structures such as support unit mounting components, handrail mounting components, side trim panel mounting components, corridor floor mounting components, and pipeline and wiring accommodating spaces into one unit. This allows for the integration of various components, such as the handrail assembly 120, side trim panel 130, corridor floor 140, pipeline 150, and wiring 152, onto the support unit 110 to form an integrated side suspension module 100. The integrated side suspension module 100 can be assembled independently and then installed onto the locomotive underframe via the support unit mounting components. This allows the integrated side suspension module 100 to be produced simultaneously with other vehicle body structures in multiple scenarios, which helps shorten the locomotive production cycle. Simultaneously, the rational layout of various components on the support unit 110 allows for orderly installation without mutual interference. This application enables modular integrated installation of various components of the integrated side suspension module 100, meeting the personalized installation needs of various components and improving the space utilization rate of the support unit 110. The support unit 110, while meeting its own structural strength requirements, is highly compatible with the installation of other components under the integrated side suspension module 100, and can achieve weight reduction. The integrated side suspension module 100 has both independence and integrity, and can be installed as a whole in the vehicle after module assembly; the sub-modules or components included in the integrated side suspension module 100 can be individually disassembled, replaced, and maintained according to process requirements or maintenance needs.

[0078] The integrated side suspension module 100, with the support unit 110 as its core and link, integrates other structures and components within the area and side-suspends them on the main load-bearing structure of the car body. This enables modular assembly and disassembly of this area of ​​the locomotive, allowing for the assembly of components for different scenarios. This reduces workload at the same workstation, enables the ground assembly of independent module auxiliary components onto the locomotive as a whole, and shortens the main waterline operation time. Ultimately, this simplifies the manufacturing process, improves product quality, increases production efficiency, reduces production and maintenance costs, and extends product lifespan. This application can be used for shunting locomotives powered by new energy sources, modularly intelligently manufactured, highly automated, and with low manufacturing and maintenance costs.

[0079] Referring to Figures 4 and 5, in some embodiments, the bracket 112 includes a U-shaped portion with an upper opening. A connecting beam 114 connects to the upper part of the bracket 112 and connects the two laterally opposite sides of the U-shaped portion. Multiple U-shaped portions of the brackets 112 and multiple connecting beams 114 together define an accommodating space. The accommodating space includes the space formed by the U-shaped portion and the space below the connecting beams 114, extending longitudinally. Due to the constraints of the pipe and line installation positions, the bracket 112 has a U-shaped structure, resulting in a large bending moment in the load-bearing area. However, after the upper connecting beams 114 laterally connect the two sides of the U-shaped portion, the stress on the load-bearing area of ​​the bracket 112 is significantly improved. Referring to Figure 7, in some embodiments, the sidewall of the U-shaped portion is provided with a wire trough mounting seat 1123, and the bottom wall of the U-shaped portion is provided with a pipe slide rail 1124, enabling the layered arrangement of the lines 152 and the pipes 150. The lines 152 are equipped with wire troughs for easy management and installation.

[0080] In some embodiments, receiving holes are formed on the bracket 112, and the receiving holes of the plurality of brackets 112 define the additional receiving space described above. In some embodiments, the bracket 112 has a protrusion that projects laterally inward relative to the connecting beam 114, and the protrusions of the plurality of brackets 112 define the operating space described above for mounting the integrated side suspension module.

[0081] Referring to Figures 5 to 7, in some embodiments, the bracket 112 has two support unit mounting members respectively disposed on its upper and lower parts, with the mounting directions of the two support unit mounting members being arranged laterally and vertically, respectively. The support unit mounting members can be support unit mounting holes 1128, which cooperate with support unit fasteners 12 to mount the bracket 112 to the locomotive underframe 10. The depth directions of the two support unit mounting holes 1128 are respectively arranged laterally and vertically, and correspondingly, the extension directions of the two support unit fasteners 12 are respectively arranged laterally and vertically. The support unit fasteners 12 can be T-bolts, and the locomotive underframe 10 is provided with sliding tracks 14 that cooperate with them.

[0082] The support unit 110 is mainly subjected to a vertical load F1 formed by its own weight and the weight of the various components mounted on it. Since the support unit 110 and the base frame 10 form a cantilever structure, a clockwise bending moment is generated under the combined action of the load F1 and the lever arm. The slide rail 14, serving as the medium for load transfer between the integrated side suspension module and the base frame, is pre-welded to both sides of the base frame and simultaneously provides vertical and horizontal load-bearing directions. The T-bolts and the slide rail 14 work together to transfer the vertical force and bending moment from the cantilever structure through a lateral reaction force F. 2x With vertical reaction force F 2yThe load is transferred to the underframe 10. Thus, by providing two support unit mounting members with installation directions arranged laterally and vertically respectively, this application can improve the connection strength between the support unit 110 and the locomotive underframe 10.

[0083] Two support unit mounting components are respectively located at the upper and lower parts of the bracket 112, ensuring that the distance between them is as large as possible and that they are installed corresponding to the upper and lower planes of the underframe as much as possible. This allows the cantilever structure of the integrated side suspension module 100 to have the greatest possible rigidity. The tensile force on the fastener of the upper support unit is set in the horizontal direction, and the tensile force on the fastener of the lower support unit is set in the vertical direction. This arrangement makes full use of the tensile force that the fasteners of the two support units can bear. In some embodiments, the inner lateral side of the bracket 112 forms a contact surface that can fit against the locomotive underframe 10, and the contact surface is located between the two support unit mounting components. Thus, the side of the support unit 110 closest to the underframe 10 fits against the vertical surface of the underframe 10, which can minimize the torsional moment of the cantilever structure on the support unit fastener 12, thereby achieving a stable connection between the entire integrated side suspension module 100 and the underframe 10.

[0084] Referring to Figure 7, in some embodiments, the main body of the bracket 112 is formed by intermittent welding of the upright plate 1121 and two surrounding plates 1122, and the weld joints are coated with weld sealant, which can prevent excessive structural welding deformation due to long weld joints and prevent corrosion at the weld joints.

[0085] Referring to Figures 8 to 10, in some embodiments, the connecting beam 114 includes a top surface, a side surface extending downwardly from the lateral outer side of the top surface, and a flange extending inwardly from the side surface; the side panel mounting member includes a plurality of side panel mounting holes 1145 formed on the flange and arranged longitudinally, the plurality of side panel mounting holes 1145 may include a plurality of alternating and regularly arranged elongated holes and a plurality of round holes; the corridor floor mounting member includes a plurality of fastener mounting seats disposed on the top surface.

[0086] The main body of the connecting beam 114 can be welded together from the profiled part 1141 and the stiffening plate 1142 to ensure structural strength. The selection of the profiled part 1141 can significantly reduce the welds caused by the splicing of plates, effectively improve the manufacturing accuracy of the connecting beam 114, simplify the manufacturing process, and improve product quality. The bottom surface of the profiled part 1141 has alternating rows of round holes and oblong holes, integrating the installation interface between the connecting beam 114 and the bracket 112, the side decorative panel installation interface, and the charger installation interface into one unit, which can flexibly adapt to the installation of different structures. The round holes and oblong holes cooperate with each other, the oblong holes can accommodate the longitudinal adjustment of different installation structures, and the round holes can ensure the longitudinal positioning of the installation structure. Fastener mounting seats (such as screw seats) 1143 are pre-welded below the connecting beam 114, and the fastener mounting seats 1143 are designed for corridor floor installation. The top and sides of the molded part 1141 are hollowed out to form multiple hollowed-out sections 1144. This can reduce weight and facilitate the installation of multiple components on the support unit 110.

[0087] Referring to Figures 2, 7, and 14, in some embodiments, the handrail assembly 120 includes a plurality of vertical bars 1222, and the lateral outer side of the bracket 112 has a receiving groove 1126. The lower regions of the plurality of vertical bars 1222 are respectively fixed to the receiving grooves 1126 of the plurality of brackets 112 by handrail fasteners 111. By installing the vertical bars 1222 in the receiving grooves 1126, it is beneficial to improve space utilization and avoid exceeding the locomotive boundary.

[0088] Referring to Figures 7 and 14, in some embodiments, the lower region of the vertical rod 1222 is fixed to the receiving groove 1126 by a plurality of handrail fasteners 111 arranged vertically at intervals. The lower region of the vertical rod 1222 is provided with a plurality of mounting holes arranged vertically at intervals, configured to cooperate with the plurality of handrail fasteners 111. In related technologies, handrails are mounted on a base frame by a plurality of horizontally arranged fasteners, resulting in insufficient vertical stability of the handrails. In the embodiments of this application, the vertical rod 1222 is fixed by a plurality of handrail fasteners 111 arranged vertically, which can improve the vertical stability of the handrail assembly 120 after installation.

[0089] Referring to Figures 17 and 18, in some embodiments, an outwardly protruding blocking portion 1225 is formed on the upper side of the lower region of the vertical rod 1222, and the blocking portion 1225 is in contact with the upper end face of the receiving groove 1126. The blocking portion 1225 can be a baffle, through which the vertical rod 1222 passes. By providing the blocking portion 1225, the minimum installation height of the handrail assembly 120 can be limited, and the blocking portion 1225 pressing against the upper end face of the receiving groove 1126 can further improve the installation stability of the handrail assembly 120 on the support unit 110. The length and width dimensions of the blocking portion 1225 can be the same as the dimensions of the upper end face of the receiving groove 1126. Since the vertical rod 1222 is too long to be fully displayed, a dashed line indicating the cutting off and hiding of a portion of the vertical rod 1222 is used in Figure 17.

[0090] Referring to Figure 14, in some embodiments, the integrated side suspension module 100 further includes multiple adjusting shims 113. These shims 113 are spaced vertically and positioned laterally between the vertical rod 1222 and the bracket 112. By providing multiple adjusting shims 113, the verticality of the vertical rod 1222 can be adjusted, as can its lateral position, ensuring that the multiple vertical rods 1222 are neatly arranged in a straight line, thus improving aesthetics.

[0091] Referring to Figures 7, 14 to 16, in some embodiments, the receiving groove 1126 (e.g., a C-groove) has a side opening on its lateral outer side. The bracket 112 also includes a plurality of handrail mounting plates 1127 vertically spaced in the side openings and having mounting holes 1129. Each adjusting shim 113 is disposed between each handrail mounting plate 1127 and the vertical bar 1222. The spacing G between adjacent handrail mounting plates 1127 allows for the insertion of adjusting shims 113. In this way, adjusting shims 113 can be conveniently disposed between the vertical bar 1222 and the plurality of handrail mounting plates 1127 respectively.

[0092] Although assembling the handrail assembly 120 and the support unit 110 on the outside of the support unit 110 facilitates installation, it is not conducive to improving space utilization and may even exceed the locomotive clearance. Therefore, in this technical solution, the installation structure of the handrail assembly 120 is hidden inside the support unit 110. However, problems such as the installation status not being observable and the installation surface height not being adjustable still exist. Therefore, this application sets the receiving groove 1126 on the support unit 110 for mounting the vertical rod 1222 and multiple (e.g., two) handrail mounting plates 1127 together to form a box-shaped structure. Sufficient installation gaps are left between the multiple handrail mounting plates 1127. These gaps allow the insertion of adjusting shims 113 to achieve leveling of the multiple handrail mounting plates. Each of the multiple handrail mounting plates 1127 can be individually fitted with adjusting shims 113, so that the verticality of the vertical rod 1222 to the horizontal plane can be adjusted by adding or removing adjusting shims 113.

[0093] Referring to Figures 11 to 13, in some embodiments, the handrail assembly 120 includes a plurality of handrail units 122 arranged longitudinally and a plurality of connecting units 124. Each connecting unit 124 is detachably connected between two adjacent handrail units 122. The handrail unit 122 is a welded frame structure and has a plurality of vertical bars 1222. The handrail assembly 120 uses the handrail units 122 and connecting units 124 as basic assembly units, which has a high reusability. A suitable number of handrail units 122 and connecting units 124 can be selected according to needs to assemble a modular handrail assembly 120. In this application, the handrail unit 122 is designed as a welded frame structure. The multiple welded joints of the frame structure are firmly connected and will not undergo relative displacement, which can avoid the problem of instability of the handrail assembly caused by the use of fasteners. Furthermore, when disassembling and assembling the handrail assembly 120, the disassembly and assembly mainly involve the handrail units 122 and connecting units 124, which can reduce the workload of disassembly and assembly and improve the efficiency of disassembly and assembly. Furthermore, since the handrail unit 122 is a welded structure and the spacing between the multiple vertical bars 1222 is not adjustable, the handrail assembly 120 can be used as a positioning fixture to assist in the assembly of the support unit 110.

[0094] In some embodiments, the assembly method of the support unit 110 may include the following steps:

[0095] Multiple supports 112 and multiple connecting beams 114 are alternately arranged longitudinally and initially connected sequentially.

[0096] Adjust the positions of multiple supports 112 and multiple connecting beams 114 so that the positions of multiple supports 112 correspond one-to-one with the positions of multiple vertical bars 1222; that is, use the handrail assembly 120 as a positioning fixture to adjust and position the supports 112.

[0097] Finally, fix the bracket 112 and the connecting beam 114 to complete the assembly of the support unit 110.

[0098] In one specific embodiment, the assembly method is as follows: Multiple supports 112 are arranged at certain intervals, and connecting beams 114 are pre-installed and fixed with mounting screws without torque. Next, the vertical rods 1222 of the handrail assembly 120 are installed on the supports 112. Using the handrail assembly 120 as a positioning fixture, the supports 112 are finely adjusted to adapt to the handrail assembly 120. Finally, the mounting screws of the connecting beams 114 and the supports 112 are tightened to complete the assembly of the support unit 110.

[0099] Referring to Figures 11, 12, and 19, the handrail assembly 120 of this application has the following characteristics: it can adapt to changes in locomotive length by increasing or decreasing the size of the handrail unit 122 itself; it can adapt to changes in locomotive length by increasing or decreasing the number of handrail units 122; it can adapt to changes in locomotive length by increasing or decreasing the size of the connecting unit 124; the handrail units 122 and the connecting unit 124 have obvious commonalities and can be used as modular components for mass production. The shape and structure of the handrail units 122 located on both sides can be different from those of the handrail units 122 located in the middle to adapt to the situation on both sides.

[0100] In some embodiments, in order to achieve a tight connection between the handrail assembly 120 and the support unit 110, the handrail unit 122 is a welded structure within a length of 3000mm, multiple handrail units 122 are as identical as possible, and the distance between two adjacent vertical bars 1222 of the handrail unit 122 is 1000mm.

[0101] Referring to Figures 17 and 18, in some embodiments, the vertical rod 1222 includes a rod body 1221 (e.g., a circular tube) with a circular cross-section. The lower region of the vertical rod 1222 has a vertical plane formed by cutting off a portion of the rod body 1221. The vertical rod 1222 also includes a mounting plate 1223 welded to the vertical plane, with multiple mounting holes formed on the mounting plate 1223. In this way, the curved surface of the rod body 1221 can be transformed into a plane, which is beneficial for realizing a planar connection between the vertical rod 1222 and the support unit 110, ensuring the effectiveness and stability of the connection. The mounting plate 1223 can be welded to the blocking part 1225 to improve the installation stability. The blocking part 1225 can assist the vertical rod 1222 in transitioning from a curved surface to a plane, creating conditions for the planar installation of the vertical rod 1222.

[0102] In one specific embodiment, half of the portion of the circular tube that passes through the baffle is removed, and the remaining half of the tube is partially welded to the mounting plate before being welded back to the baffle. The mounting plate has two threaded holes for mounting the handrail assembly, arranged vertically for threaded connection between the handrail assembly 120 and the external support structure. The vertical arrangement of the connection points between the handrail assembly 120 and the support unit 110 significantly improves the stability of the handrail assembly 120 after installation.

[0103] The blocking part 1225 is perpendicular to the mounting plate 1223. The upper plane of the receiving groove 1126 of the support unit 110 is perpendicular to the mounting plane of the handrail mounting plate 1127. In the above two sets of perpendicular welded structures, the lower plane of the blocking part 1225 presses against the upper plane of the receiving groove 1126, and the mounting plate 1223 presses against the mounting plane on the inner side of the handrail mounting plate 1127. It is then fixed by two sets of vertically arranged handrail fasteners 111. Through this technical solution, not only are the transverse planes of the two mounting structures in contact, but the two vertical mounting planes are also in contact. After being fixed by fasteners, the original single-plane close-fitting installation structure of the handrail assembly can be upgraded to two sets of mutually perpendicular planes being closely fitted, which can greatly improve the stability of the handrail assembly 120 after installation.

[0104] Referring to Figures 12 and 19, in some embodiments, the handrail unit 122 includes a frame and a plurality of vertical bars 1222 welded to the frame and arranged longitudinally at predetermined intervals. Let X represent the predetermined interval, let X1 represent the longitudinal distance between the first side edge of the frame and the nearest vertical bar 1222, let X2 represent the longitudinal distance between the second side edge of the frame and the nearest vertical bar 1222, and let X3 represent the longitudinal distance between two adjacent frames. Then, the formula X = X1 + X2 + X3 is satisfied. With this arrangement, the distance between the vertical bar 1222 at the tail end of the previous handrail unit 122 and the vertical bar 1222 at the head end of the next handrail unit 122 is the same as the distance between two adjacent vertical bars 1222 within each handrail unit 122. In this way, the multiple vertical bars 1222 of the handrail assembly 120 are evenly arranged at the same interval, which can be adapted to the multiple supports 112 that are also arranged at the same interval, ensuring that the handrail assembly 120 can be properly installed and fitted onto the support unit 110.

[0105] Referring to Figure 12, in some embodiments, the frame includes a bent retaining rod 1224 and longitudinally extending straight rods 1226. The two ends of the retaining rod 1224 are welded to two of the multiple vertical rods located on either side. The straight rods 1226 are welded between two adjacent vertical rods 1222. The retaining rod 1224 may have four bending angles and multiple longitudinal and vertical extensions. This arrangement reduces the amount of welding and allows the straight rods 1226 to be as short as possible, reducing manufacturing costs. In one specific embodiment, the main body of the handrail unit 122 is welded together from one retaining rod 1224, two straight rods 1226, and three vertical rods 1222. The retaining rod 1224 is bent at 90 degrees four times.

[0106] Referring to Figures 19 to 26, in some embodiments, the handrail unit 122 has connectors 1228 on both longitudinal sides, and the connectors 1228 form mating grooves 1229. Both ends of the connecting unit 124 are respectively fixed to the mating grooves 1229 of the two handrail units 122 by fasteners 126. Both ends of the connecting unit 124 form insertion portions 1242 for inserting into the mating grooves 1229. A step is formed at the connection between the insertion portion 1242 and the main body of the connecting unit 124 to ensure a tight fit with the mating grooves 1229. By inserting into the mating grooves 1229 and fixing with fasteners 126, the reliability of the connection between the handrail unit 122 and the connecting unit 124 can be ensured. The connectors 1228 can be welded to the handrail unit 122.

[0107] In some embodiments, the fastener 126 includes a screw 1262 and a nut 1264. A through hole h1 and a regular hexagonal hole h2 matching the nut 1264 are respectively formed on the two opposite walls of the mating groove 1229. The regular hexagonal hole h2 can limit the position of the nut 1264, preventing the nut 1264 from rotating, thus eliminating the need for a wrench during installation. Furthermore, the nut 1264 can be embedded in the regular hexagonal hole h2, improving both aesthetics and safety.

[0108] In some embodiments, the position of the end of the connecting unit 124 in the mating groove 1229 is longitudinally adjustable to accommodate installation errors between adjacent handrail units 122. Adjustment margins can be provided by setting the dimensions of the through hole h1 and the regular hexagonal hole h2 to be larger than the dimensions of the screw 1262 and the nut 1264, respectively.

[0109] In one specific embodiment, the connecting unit 124 uses an M8X30 socket head cap screw and an M8 standard nut, along with a large washer, to connect with the connector 1228, thereby achieving the connection between adjacent handrail units 122. Theoretically, the number of handrail units 122 can be increased indefinitely to complete the assembly of the entire vehicle's handrails. The connector 1228 has a φ13mm through hole on side A and a regular hexagonal hole on side B. The side length of the regular hexagonal hole is slightly longer than the side length of the M8 nut. A groove is formed in the middle of the connector 1228 to mate with the end of the connecting unit 124, and the distance between the two sides of the groove is slightly larger than that of the end of the connecting unit 124. The two ends of the connecting unit 124 are semi-circular in shape to facilitate axial movement between the end and the connector 1228, and also have an aesthetically pleasing appearance. Both ends of the connecting unit 124 have φ11mm through holes. The φ13mm through hole on connector 1228 and the φ11mm through hole at the end of connector unit 124 are used in conjunction with M8X30 screws and M8 nuts to compensate for installation errors on the production site when assembling adjacent handrail units 122. A regular hexagonal hole is provided on side B of connector, which directly acts as a "wrench" when installing fasteners. Only an M8 Allen wrench is needed to assemble the handrail unit, avoiding the hassle of using two wrenches. As the screws are tightened, the nut extends into the regular hexagonal hole on side B. The outer surface of the nut is lower than the outer plane of side B of connector, effectively preventing the fastener head from being exposed and potentially causing injury to drivers and passengers.

[0110] Referring to Figures 27 and 28, in some embodiments, the side trim panel 130 includes a panel 132 and a transition member 134 that are fastened to each other by fasteners. The transition member 134 is fixed to the connecting beam 114 and has a through hole 1342. The panel 132 is located laterally outside the transition member 134 and has a hook 1322 that passes through the through hole 1342. By setting hooks 1322, on the one hand, the hooks 1322 can be hooked onto the transition piece 134 to restrict the relative position of the transition piece 134 and the panel 132, limiting the vertical, horizontal, and longitudinal movement space of the panel 132 and preventing the panel 132 from detaching from the transition piece 134; on the other hand, when installing the side trim panel 130, the transition piece 134 can be fixed to the support unit 110 first, and then the panel 132 can be hung on the transition piece 134 using hooks 1322. At this time, the operator can easily and effortlessly adjust the position of the panel 132. After the position is adjusted, the panel 132 is connected to the transition piece 134 using fasteners to complete the installation of the side trim panel 130. In this way, one operator can independently complete the position adjustment and installation of the side trim panel 130.

[0111] Referring to Figures 36 and 37, in some embodiments, the integrated side-mounted module 100 further includes a display lamp mounting profile 160, which covers the lateral outer side of the side trim panel 130 to prevent the hook 1322 from disengaging from the through hole 1342. When the panel 132 moves laterally outward relative to the transition member 134 by an excessive distance, the hook 1322 on the panel 132 may disengage from the through hole 1342. This application provides that the display lamp mounting profile 160 covers the lateral outer side of the side trim panel 130 to limit the lateral outward movement of the panel 132, thereby preventing the hook 1322 from disengaging from the through hole 1342 and ensuring that the hook 1322 is always inserted into the through hole 1342. Therefore, even if the fasteners between the panel 132 and the transition piece 134 become loose, the panel 132 will remain attached to the transition piece 134 by the engagement of the hook 1322 and the through hole 1342, thus preventing the side trim panel 130 from falling off the support unit 110. The transition piece 134 can be securely fixed to the support unit 110 by anti-loosening fasteners (such as anti-loosening nuts or double nuts).

[0112] Referring to Figure 35, in some embodiments, the hook 1322 includes a vertical segment s1, a horizontal segment s2, and an inclined segment s3 that transition smoothly in sequence. The horizontal segment s2 extends laterally inward from the lower end of the vertical segment s1, and the lower end of the inclined segment s3 is inclined laterally inward relative to its upper end. This configuration of the hook 1322 allows it to engage well with the plate 132 via the vertical segment s1 and facilitates welding to it. Furthermore, it effectively restricts the relative positions of the plate 132 and the transition piece 134 in multiple directions to prevent detachment. Additionally, it allows for easy hanging into the perforation 1342, facilitating the assembly of the side trim panel 130 and its installation on the support unit 110.

[0113] The transverse segment s2 has a length L, and the inclined segment s3 forms an inclined angle θ with the transverse segment s2. The values ​​of the length L and the inclined angle θ can be set according to the actual situation to ensure the anti-detachment function of the hook 1322 and to ensure that the hook 1322 can be easily hung in the perforation 1342. In the embodiment of this application, the transverse distance between the indicator light mounting profile 160 and the side trim panel 130 is less than the length L of the transverse segment s2, thereby preventing the hook 1322 from falling out of the perforation 1342 and ensuring the reliability of the side trim panel 130 installation. The indicator light mounting profile 160 can cover the upper transverse outer side of the side trim panel 130.

[0114] Referring to Figures 36 and 37, in some embodiments, the handrail assembly 120 is secured to the bracket 112 by handrail fasteners 111, and a side panel 130 covers the lateral outer side of the handrail fasteners 111 to prevent them from loosening. The handrail fasteners 111 are mounted laterally, with their ends located laterally outside the support unit 110. The side panel 130 covers the outer side of the ends of the handrail fasteners 111 to provide restraint, thereby preventing the handrail fasteners 111 from loosening. In some embodiments, a light fixture mounting profile 160 presses against the corridor floor 140. Under the weight of the light fixture mounting profile 160 and the light fixtures mounted on it, the light fixture mounting profile 160 applies downward pressure to the corridor floor 140 to prevent it from loosening.

[0115] In the embodiments of this application, the side trim panel 130 is used to prevent the handrail assembly 120 from detaching during installation, and the indicator light mounting profile 160 is used to prevent the side trim panel 130 and the corridor floor 140 from detaching during installation. This application arranges multiple functional components of the integrated side suspension module 100 in an orderly manner, utilizing the structural characteristics of each component to form a progressively interlocking anti-detachment chain. This progressive installation structure achieves anti-detachment, improving the overall safety and reliability of the module, preventing deformation during the overall assembly and disassembly of the integrated side suspension module, and enabling quick assembly and disassembly of the entire integrated side suspension module. This eliminates the need for individual anti-detachment measures for each installation component, while also saving installation space and materials. The interlocking and compact installation of multiple components within the integrated side suspension module creates conditions for arranging multiple components within a limited space. The application of this interlocking anti-detachment structure reduces the amount of anti-loosening fasteners used, lowers product costs, and improves assembly and disassembly efficiency.

[0116] The indicator light mounting profile 160 can be secured with anti-loosening fasteners (such as anti-loosening nuts or double nuts) to prevent detachment, providing reliable protection for the entire interlocking anti-detachment chain. The indicator light mounting profile 160 can be fixed to the vertical bar 1222 of the handrail assembly 120.

[0117] In some embodiments, the plate 132 is adjustable in both vertical and horizontal directions relative to the transition member 134, and the transition member 134 is adjustable in longitudinal direction relative to the connecting beam 114. Referring to Figures 27 to 30 and 34, the plate 132 has a first slide rail 1324 arranged vertically, and a first fastener 1362 (e.g., a T-bolt) is adjustable in position within the first slide rail 1324. The vertical position adjustment of the plate 132 relative to the transition member 134 is achieved by the first slide rail 1324 and the first fastener 1362. The transition member 134 may have a second slide rail 1344 arranged longitudinally, and the integrated side suspension module 100 includes a second fastener 1366 (e.g., a T-bolt) adjustable in position within the second slide rail 1344 and connected to the support unit 110. The longitudinal position adjustment of the transition member 134 relative to the support unit 110 is achieved by the second slide rail 1344 and the second fastener 1366. Therefore, the side trim panel 130 can be adjusted vertically and longitudinally. Furthermore, the side trim panel 130 can be adjusted laterally by placing a shim between the panel 132 and the transition piece 134. By providing multi-directional positional adjustability of the side trim panel 130, installation with larger errors can be accommodated, facilitating the adjustment of multiple side trim panels 130 to a mutually aligned position, ensuring a neat and uniform appearance of the side trim panels 130, and improving the vehicle's aesthetics. The side trim panel 130 can have multiple first slide rails 1324 arranged longitudinally at intervals, and correspondingly, the number of first fasteners 1362, transition pieces 134, and second slide rails 1344 is also multiple.

[0118] Those skilled in the art should understand that the relative positions of the plate 132 and the transition piece 134, as well as the relative positions of the transition piece 134 and the connecting beam 114, can be adjusted not only by using a slide rail and fasteners, but also by using multiple connecting holes arranged in a specific direction and fasteners, long holes set in a specific direction and fasteners, multiple slots arranged in a specific direction and protrusions, guide rails and sliders, etc.

[0119] Referring to Figures 27, 31, and 32, in some embodiments, the plate 132 is a bent component and includes a main region 1321 and a lower region 1323. The main region 1321 extends vertically and longitudinally, while the lower region 1323 is inclined laterally inward relative to the main region 1321. A bend B1 is provided in the lower middle part of the plate 132, thereby forming the main region 1321 and the lower region 1323. Through the bending design, the rigidity of the middle part of the plate 132 can be improved while preventing the side trim 130 from exceeding the locomotive clearance after installation. The plate 132 can be formed into a rectangular bend by three-sided pressing of carbon steel sheet with a thickness of less than 2mm. A bend B2 is provided at the bottom edge of the plate 132 to improve the peripheral rigidity of the thin plate. Laser welding can be used to splice the parts circled in Figure 31 to avoid the influence of thermal deformation on the flatness of the plate 132. Since the plate 132 is too long to be fully displayed, a dashed line is used in Figure 31 to indicate that a part of the plate 132 has been cut off and hidden.

[0120] Referring to Figures 28, 29, and 30, a first slide rail 1324 is provided in the main body region 1321, and a third slide rail 1326 is also provided in the lower region 1323. A third fastener 1364 (e.g., a T-bolt) is adjustablely positioned within the third slide rail 1326. The transition member 134 can also be fixed to the plate 132 by the third fastener 1364. The projection of the third slide rail 1326 onto a plane parallel to the main body region 1321 extends vertically. By adding the third slide rail 1326 and the third fastener 1364, the connection reliability between the transition member 134 and the plate 132 is further improved.

[0121] Referring to Figures 28 and 33, in some embodiments, the panel 132 is welded (e.g., partially welded) to a support plate 1328. The first slide rail 1324 and the third slide rail 1326 are welded to the support plate 1328, and multiple welded locations on the support plate 1328 and the first slide rail 1324 and the third slide rail 1326 are staggered. The first slide rail 1324 and the third slide rail 1326 are not directly welded to the panel 132, but are transitioned through the support plate 1328. This technical solution not only improves the rigidity of the corresponding area of ​​the panel 132, but also avoids deformation of the panel 132 due to welding by staggering the multiple welded locations of the support plate 1328 on the panel 132 and the first slide rail 1324 and the third slide rail 1326 on the support plate 1328. This provides excellent technical support for the rigidity, flatness, and installation of the side trim panel 130, meeting the aesthetic requirements of the side trim panel 130. The support plate 1328 may have folded edges s. The folded edges s on the upper and lower sides of the support plate 1328 are welded to the return bends of the plate body 132 to improve the rigidity of the middle part of the thin plate. In Figure 33, the large circles represent the welded areas of the support plate 1328 on the plate body 132, and the small circles represent the welded areas of the first slide rail 1324 and the third slide rail 1326 on the support plate 1328. The welded areas of the support plate 1328 are staggered with the welded areas of the first slide rail 1324 and the third slide rail 1326 to avoid weld concentration, disperse the heat effect of welding, and prevent welding deformation. Furthermore, the width of the support plate 1328 may be more than 20 mm larger than the width of the first slide rail 1324 and the third slide rail 1326 to further avoid weld concentration and welding deformation.

[0122] As shown in Figure 34, the transition member 134 can be made of angle steel to ensure sufficient strength. The transition member 134 can have a vertical portion and an inclined portion corresponding to the main body region 1321 and the lower region 1323. The transition member 134 is welded to the second slide rail 1344 to ensure connection strength. The transition member 134 has multiple mating holes 1346 that respectively mate with the first fastener 1362 and the third fastener 1364.

[0123] The two mounting methods of the side trim panel 130 relative to the support unit 110 in this application are as follows:

[0124] The first method is carried out when the installation dimensions are accurate and there is sufficient installation space. The panel 132 and the transition piece 134 can be installed using the first slide rail 1324 and the first fastener 1362. After that, the transition piece 134 is connected to the support unit 110 using the second slide rail 1344 and the second fastener 1366, which can smoothly complete the installation of the side trim panel 130.

[0125] The second method is used when there are errors in the installation fit dimensions and insufficient installation space. The connection between the panel 132 and the transition piece 134 is disconnected. First, the transition piece 134 is installed on the support unit 110 via the second slide rail 1344 and the second fastener 1366. Then, the hook 1322 is inserted into the through hole 1342 on the transition piece 134, so that the panel 132 is hung on the transition piece 134 via the hook 1322. After that, one operator can independently complete the three-way dimensional adjustment and installation of the side trim panel 130.

[0126] While perfectly accurate dimensions on-site are often an ideal scenario, minor adjustments to the side trim panel's installation position are unavoidable during most installation processes. This is where the hooks 1322 and perforations 1342 in this technical solution become crucial. By hanging the panel 132 onto the transition piece 134, the operator can independently adjust it in three directions to ensure a uniform and neat appearance after installation.

[0127] To highlight the decorative function of the side trim panel 130, structures such as the first slide rail 1324, the first fastener 1362, the third slide rail 1326, the third fastener 1364, and the hook 1322 are all arranged on the mounting side of the side trim panel 130. After installation, the side trim panel 130 conceals various devices it protects, while simultaneously transforming the appearance of different devices into a unified look for the side trim panel 130, thus achieving the most important functions of the side trim panel 130: decoration and protection.

[0128] Referring to FIG38, in some embodiments, the indicator light mounting profile 160 extends longitudinally and includes a profile body 162 and a lower profile region 164. The lateral inner side of the profile body 162 forms a profile mounting portion 161 for mounting the indicator light mounting profile 160 to the component to be mounted. The lateral outer side of the profile body 162 forms an indicator light mounting groove 163. The lateral middle portion of the profile body 162 forms a wiring cavity 165 communicating with the indicator light mounting groove 163 and the lateral inner space of the profile body 162 through a wire through hole 167. The indicator light mounting profile 160 is mounted on the handrail assembly 120.

[0129] The profile mounting section 161 may include a slide rail configured to mate with fasteners. Referring to FIG36, the integrated side suspension module 100 also includes a profile mounting member 166, which mounts the indicator light mounting profile 160 onto the vertical rod 1222 of the handrail assembly 120 by the engagement of fasteners provided on the slide rail and the profile mounting member 166. The profile mounting member 166 may include an arc-shaped encircling portion and straight extensions extending from both sides of the arc-shaped encircling portion, with mounting holes formed on the straight extensions to mate with fasteners. The number of indicator light mounting slots 163 may be one or more. The indicator light mounting slots 163 are configured to mount indicator lights, which may be configured to indicate different states of the locomotive by displaying different colors and / or different intensities of light, such as low power, charging, and fully charged battery. The wall of the indicator light mounting slot 163 may be formed with a snap-fit ​​portion 168 configured to fix the indicator light, which may be in the form of a protrusion, slot, ring, or claw. The wiring cavity 165 is configured for wiring. The wire hole 167 allows the electrical connection wires of the indicator lights to extend from the lateral outer side to the lateral inner side of the profile body 162 and be hidden.

[0130] Referring to Figures 37 and 38, the lower region 164 of the profile extends downward from the lateral outer side of the profile body 162 and covers the lateral outer side of the side trim 130. The lower region 164 can shield the side trim 120 from possible installation errors and also provide anti-detachment for the side trim 130. In addition, the lower region 164 can also form a fluorescent sticker mounting part 169 (e.g., a fluorescent sticker mounting groove), making the function of the indicator light mounting profile 160 more diversified, while achieving a lightweight effect.

[0131] The indicator light mounting profile 160 of this application realizes the concept of functional integration, not only completing its own installation and the installation of the charging indicator light, but also serving a decorative purpose. One side of the corridor floor is the vehicle's mechanical compartment, and the other side is the handrail assembly. However, the handrail's protective range is limited, and the corridor floor can become slippery in winter and rainy seasons. The indicator light mounting profile 160, installed below the handrail assembly and protruding above the corridor floor, functions as a waistline decoration for the entire vehicle and acts as a baseboard for the corridor, providing necessary protection for drivers and passengers. In the embodiments of this application, the indicator light mounting profile 160 has the characteristics of multi-functional integration, including: light strip installation, wiring, cable threading, self-installation, protection, anti-detachment, and external decoration.

[0132] In some embodiments, the assembly method of the integrated side suspension module 100 includes the following steps:

[0133] The handrail assembly 120 is fixed to the lateral outer side of the support unit 110 by the handrail fastener 111;

[0134] The side trim panel 130 is fixed to the support unit 110 such that the side trim panel 130 covers the lateral outer side of the handrail fastener 111 to prevent it from loosening; wherein, the side trim panel 130 includes a plate body 132 and a transition member 134 that are fixed to each other by fasteners, the transition member 134 is fixed to the support unit 110 and has a through hole 1342, the plate body 132 is located on the lateral outer side of the transition member 134 and has a hook 1322 that passes through the through hole 1342;

[0135] Fix the corridor floor 140 to the upper side of the support unit 110;

[0136] The display light mounting profile 160 is secured to the handrail assembly 120 with anti-loosening fasteners, so that the display light mounting profile 160 presses against the corridor floor 140 and covers the lateral outer side of the side panel 130 to prevent the hook 1322 from coming out of the perforation 1342.

[0137] Following the above installation sequence, a cleverly coordinated, progressively layered installation scheme is ultimately formed within the integrated side suspension module. This ensures that subsequent installation structures prevent detachment from preceding structures, creating a sequentially progressive interlocking anti-detachment chain. Once this interlocking anti-detachment chain is established within the integrated side suspension module, even if fasteners on system components loosen or fall off, the entire module will not collapse or fail. This progressively progressive interlocking anti-detachment chain ensures close cooperation among multiple components within the integrated side suspension module, creating favorable conditions for the quick and easy assembly and disassembly of the entire integrated side suspension module.

[0138] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the embodiments disclosed in this application is limited to these examples; within the framework of the embodiments of this application, the technical features of the above embodiments or different embodiments can also be combined, and there are many other variations of different aspects of the embodiments of this application as described above, which are not provided in detail for the sake of brevity. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the embodiments of this application should be included within the protection scope of the embodiments of this application.
