[0075] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0076] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0077] As mentioned in the above background technology, the present application realizes that there are some shortcomings in the installation method of multiple components in the side area of ​​the locomotive in the current technology. Specifically, the side beam is directly welded to the chassis, with various forms and quantities, and it is necessary to use a positioning tool to limit the position. It is almost impossible to adjust after welding, and the fault tolerance rate is low. The welded side beam structure has a single function. The installation of components such as side decorative panels, pipelines, wire ducts, corridor floors, etc. requires the installation of additional mounting structures, and then the mounting structures are welded to the side beams. The various mounting structures are intertwined, and the installation error rate is high, and the production efficiency is low. The mounting structures of multiple components all need to be welded to the side beams. The errors of each component itself plus the welding errors may cause interference between the components during installation, and even require rework and repositioning welding. The number of welding mounting seats for each component is large, the relative position size requirements are high, the number of positioning tools is large, and the size positioning is not easy to ensure. The handrails, side decorative panels, pipelines, wire ducts, corridor floors and other components are installed separately on the main assembly pipeline. The main assembly pipeline of locomotive production occupies too much, which is not conducive to reducing the locomotive production cycle. The simultaneous cross-installation of multiple professions at the same assembly station can easily lead to confusion in the assembly sequence, resulting in errors or even rework. Pipes and cable ducts are installed on the upper side of the side beam, and the space utilization rate in the height direction is low. In order to solve the problems existing in the prior art, the present application proposes one or more embodiments to be described below.

[0078] refer to Figure 2 and Figure 3The present invention proposes an integrated side suspension module 100 for a locomotive, comprising: a support unit 110 and a handrail assembly 120, a side trim 130, a corridor floor 140, a pipeline 150, and a line 152 integrated in the support unit 110. The integrated side suspension module 100 defines longitudinal, transverse and vertical directions, which correspond to the length direction, width direction and height direction of the locomotive, respectively. The integrated side suspension module 100 is respectively joined to the locomotive chassis and suspended on opposite sides in the transverse direction. The side of the integrated side suspension module 100 joined to the vehicle body chassis is taken as the transverse inner side, and the side of the integrated side suspension module 100 away from the vehicle body chassis is taken as the transverse outer side.

[0079] refer to Figure 4 The support unit 110 includes a plurality of brackets 112 spaced apart in the longitudinal direction and a plurality of connecting beams 114 spaced apart in the longitudinal direction, and each connecting beam 114 is detachably connected between adjacent brackets 112. The plurality of brackets 112 and the plurality of connecting beams 114 are combined to obtain a frame structure extending in the longitudinal direction, which is used to carry a variety of components in the side areas of various locomotives. The support unit 110 itself constitutes a modular structure that can be independently produced and assembled. The support unit 110 uses the brackets 112 and the connecting beams 114 as basic components, and has a high reuse rate. The length of the support unit 110 in the longitudinal direction can be adjusted by adjusting the number of brackets 112 and connecting beams 114 to meet the individual needs of vehicle models of different lengths.

[0080] The bracket 112 and the connecting beam 114 can be connected in a detachable manner so that the number can be increased or decreased by disassembly and assembly, thereby adjusting the longitudinal length of the supporting unit 110. Figure 7 Connecting beam mounting seats 1125 are provided on both longitudinal sides of the bracket 112. The connecting beam mounting seats 1125 can support the longitudinal side areas of the connecting beam 114 and are provided with mounting holes. The mounting holes cooperate with fasteners to realize a detachable connection between the bracket 112 and the connecting beam 114.

[0081] Figure 5 FIG. 1 is a schematic diagram showing the functional division of the support unit 110 according to an embodiment of the present invention, referring to FIG. Figure 2 and Figure 5 The bracket 112 forms a mounting area a between the support unit 110 and the vehicle body frame on the lateral inner side, and the mounting area has a portion for mounting the support unit 110 to the vehicle frame 10 ( Figure 6) of the support unit mounting member. A handrail mounting area d is formed on the lateral outer side of the bracket 112, and the mounting area has a handrail mounting member, so that the handrail assembly 120 is fixed to the lateral outer side of the bracket 112. A side trim mounting area e is formed on the lateral outer side of the connecting beam 114, and the mounting area has a structure for installing the side trim, so that the side trim 130 is fixed to the lateral outer side of the connecting beam 114. A corridor floor mounting area c is formed on the upper side of the connecting beam 114, and the mounting area has a corridor floor mounting member, so that the corridor floor 140 is fixed to the upper side of the connecting beam 114. A brake pipeline and electrical line installation area b is formed inside the support unit 110, and the installation area has an accommodation space for accommodating pipelines 150 and lines 152. An expansion equipment installation area g is also formed inside the support unit 110, and the installation area has an additional accommodation space spaced apart from the accommodation space in the lateral direction. The lower part of the bracket 112 also forms a charger socket installation area f, which has a charger socket installation part, so that the charger socket is installed at the lower part of the bracket 112. The support unit 110 also has an operation area h located between the connecting beam 114 and the bottom frame, which reserves the necessary operation space for installing the integrated side suspension module 100. Each functional area of ​​the support unit 110 performs its own duties, and the layout is reasonable, which cleverly and fully utilizes the areas and spaces in various directions of the support unit 110.

[0082] In an embodiment of the present invention, the support unit 110 integrates a plurality of mounting structures such as a support unit mounting part, a handrail mounting part, a side trim mounting part, a corridor floor mounting part, and a pipe and line accommodating space, so that a plurality of components such as a handrail assembly 120, a side trim 130, a corridor floor 140, a pipe 150, and a line 152 can be integrated into the support unit 110 to form an integrated side suspension module 100. The integrated side suspension module 100 can be independently assembled and then installed to the locomotive chassis through the support unit mounting part, so that the integrated side suspension module 100 can be produced synchronously with other structures of the vehicle body in multiple scenes, which is conducive to shortening the locomotive production cycle; at the same time, the layout of various components on the support unit 110 is reasonable, and orderly installation can be achieved without mutual interference. The present invention can realize the modular integrated installation of various components of the integrated side suspension module 100, meet the personalized installation requirements of various components of the integrated side suspension module 100, and improve the space utilization rate of the support unit 110. The support unit 110 not only meets its own structural strength, but also highly matches the installation of other components under the integrated side suspension module 100 and can achieve lightweight. The integrated side suspension module 100 has both independence and integrity, and can be installed as a whole after the module is assembled; the submodules or components included in the integrated side suspension module 100 can be individually disassembled, replaced, and maintained according to process requirements or maintenance needs.

[0083] The integrated side suspension module 100 takes the support unit 110 as the core and link. By integrating other structures and components in the area and hanging them on the main load-bearing structure of the car body, the modular disassembly and assembly of the locomotive in this area can be realized, and the assembly of components in different scenes can be realized. The workload at the same workstation can be reduced, and the ground assembly of independent module accessories can be realized as a whole, shortening the main pipeline working hours. Ultimately, the manufacturing process can be simplified, product quality can be improved, production efficiency can be improved, production cost and maintenance cost can be reduced, and product service life can be increased. The present invention can be used for shunting locomotives that use new energy as power, are modularly intelligently manufactured, have a high degree of automation, and have low manufacturing and maintenance costs.

[0084] refer to Figure 4 and Figure 5 In some embodiments, the bracket 112 includes a U-shaped portion with an upper opening, and a connecting beam 114 is connected to the upper portion of the bracket 112 and connects the two opposite lateral sides of the U-shaped portion. The U-shaped portions of multiple brackets 112 and multiple connecting beams 114 jointly define a storage space. The storage space includes the storage space formed by the U-shaped portion and the space below the connecting beam 114, and the storage space extends in the longitudinal direction. Due to the constraints of the installation position of the pipeline and the line, the bracket 112 itself has a U-shaped structure, resulting in a large bending moment in the bearing area of ​​the bracket 112. However, after the upper connecting beam 114 is laterally connected on both sides of the U-shaped portion, the force condition of the bearing area of ​​the bracket 112 is qualitatively improved. Reference Figure 7 In some embodiments, the side wall 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 pipeline slide rail 1124, so as to realize the layered arrangement of the line 152 and the pipeline 150. The line 152 is provided with a wire trough for easy management and installation.

[0085] In some embodiments, a receiving hole is 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 protruding portion protruding laterally inward relative to the connecting beam 114, and the protruding portions of the plurality of brackets 112 define the operating space described above for installing the side suspension module.

[0086] refer to Figures 5 to 7 In some embodiments, the bracket 112 has two support unit mounting members respectively arranged at the upper and lower parts thereof, and the mounting directions of the two support unit mounting members are respectively arranged in the horizontal direction and the vertical direction. The support unit mounting member can be a support unit mounting hole 1128, which cooperates with the support unit fastener 12 to mount the bracket 112 to the locomotive chassis 10. The hole depth directions of the two support unit mounting holes 1128 are respectively arranged in the horizontal direction and the vertical direction, and accordingly, the extension directions of the two support unit fasteners 12 are respectively arranged in the horizontal direction and the vertical direction. The support unit fastener 12 can be a T-bolt, and the locomotive chassis 10 is provided with a slideway 14 that cooperates with it.

[0087] The support unit 110 is mainly subjected to the vertical load F1 formed by its own weight and the weight of various components installed on it. Since the support unit 110 and the base frame 10 are cantilever structures, a clockwise bending moment is formed under the combined action of the load F1 and the lever arm. The slideway 14 is welded to both sides of the base frame in advance as a medium for load transmission between the side suspension module and the base frame, and has both vertical and horizontal load-bearing directions. The T-bolts and the slideway 14 cooperate with each other to transfer the vertical force and bending moment brought by the cantilever structure through the lateral reaction force F 2x and vertical reaction force F 2y The support unit 110 is transferred to the underframe 10. Therefore, the present invention can improve the connection strength between the support unit 110 and the underframe 10 of the locomotive by providing two support unit mounting members which are respectively installed in the horizontal direction and the vertical direction.

[0088] The two support unit mounting parts are respectively arranged at the upper and lower parts of the bracket 112, ensuring that the distance between the two is as large as possible, and are installed as much as possible corresponding to the upper and lower planes of the chassis, so that the cantilever structure of the integrated side suspension module 100 has the greatest possible rigidity. The positive tension received by the upper fastener is set in the horizontal direction, and the positive tension received by the lower fastener is set in the vertical direction. Such an arrangement fully utilizes the positive tension that the two fasteners can bear. In some embodiments, the lateral inner side of the bracket 112 forms a fitting surface that can fit with the locomotive chassis 10, and the fitting surface is located between the two support unit mounting parts. Therefore, the side of the support unit 110 close to the chassis 10 fits with the vertical surface of the chassis 10, which can maximize the elimination of 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 chassis 10.

[0089] refer to Figure 7 In some embodiments, the main body of the bracket 112 is formed by intermittent welding of a vertical plate 1121 and two enclosure plates 1122, and weld sealant is applied to the welds to avoid excessive structural welding deformation due to long welds and to avoid rust at the weld positions.

[0090] refer to Figures 8 to 10 In some embodiments, the connecting beam 114 includes a top surface, a side surface extending downward from the lateral outer side of the top surface, and a flange extending inward from the side surface; the side trim panel mounting member includes a plurality of side trim panel mounting holes formed on the flange and arranged longitudinally, and the plurality of side trim panel mounting holes may include a plurality of oblong holes and a plurality of round holes arranged alternately and regularly; the corridor floor mounting member includes a plurality of fastener mounting seats arranged on the top surface.

[0091] The main body of the connecting beam 114 can be welded by a profiled part 1141 and a rib plate 1142 to ensure structural strength. The selection of the profiled part 1141 can greatly reduce the welds caused by the splicing of the plates, effectively improve the manufacturing accuracy of the connecting beam 114, simplify the manufacturing process, and improve product quality. The circular holes and the oblong holes on the bottom surface of the profiled part 1141 are arranged alternately in rows, integrating the installation interface between the connecting beam 114 and the bracket 112, the side decorative plate installation interface, and the charger installation interface, which can be flexibly adapted to the installation of different structures. The circular hole and the oblong hole cooperate with each other, the oblong hole can adapt to the longitudinal adjustment amount of different installation structures, and the circular hole can ensure the longitudinal positioning of the installation structure. The pre-welded fastener mounting seat (such as a screw seat) 1143 below the connecting beam 114 is used for corridor floor installation. The top surface and the side surface of the profiled part 1141 are hollowed out to form a plurality of hollow parts 1144, which can achieve the effect of weight reduction on the one hand, and facilitate the installation of various components on the support unit 110 on the other hand.

[0092] refer to Figure 2 , Figure 7 and Fig.14 In some embodiments, the handrail assembly 120 includes a plurality of vertical rods 1222, and a receiving slot 1126 is provided on the lateral outer side of the bracket 112. The lower areas of the plurality of vertical rods 1222 are respectively fixed in the receiving slots 1126 of the plurality of brackets 112 by the handrail fasteners 111. By installing the vertical rods 1222 in the receiving slots 1126, it is helpful to improve space utilization and avoid exceeding the limits of the locomotive.

[0093] refer to Figure 7 and Fig.14 In some embodiments, the lower area of ​​the vertical rod 1222 is fixed in the receiving groove 1126 by a plurality of handrail fasteners 111 arranged along the vertical interval. The lower area of ​​the vertical rod 1222 is provided with a plurality of mounting holes arranged along the vertical interval, which are used to cooperate with the plurality of handrail fasteners 111. The present application recognizes that in the prior art, the handrail is installed on the base frame by a plurality of fasteners arranged horizontally, resulting in insufficient vertical stability of the handrail. To solve this technical problem, in an embodiment of the present invention, the vertical rod 1222 is fixed by a plurality of handrail fasteners 111 arranged along the vertical interval, which can improve the vertical stability of the handrail assembly 120 after installation.

[0094] refer to Fig.17 and Fig.18In some embodiments, a blocking portion 1225 protruding outward is formed on the upper side of the lower area of ​​the vertical rod 1222, and the blocking portion 1225 is in contact with the upper end surface of the receiving groove 1126. The blocking portion 1225 may be a baffle, and the vertical rod 1222 is passed through the baffle. By providing the blocking portion 1225, the minimum installation height of the handrail bar assembly 120 can be limited, and the blocking portion 1225 is pressed on the upper end surface of the receiving groove 1126, which can further improve the installation stability of the handrail bar assembly 120 on the supporting unit 110. The length and width dimensions of the blocking portion 1225 may be the same as the dimensions of the upper end surface of the receiving groove 1126. It should be noted that since the vertical rod 1222 extends too long to be fully displayed, Fig.17 The dotted line that cuts off the vertical rod 1222 indicates that a portion of the vertical rod 1222 is cut off and hidden.

[0095] refer to Fig.14 In some embodiments, the integrated side suspension module 100 further includes a plurality of adjustment pads 113, which are arranged at intervals in the vertical direction and are located between the vertical rod 1222 and the bracket 112 in the lateral direction. By providing a plurality of adjustment pads 113, the verticality of the vertical rod 1222 can be adjusted on the one hand, and the lateral position of the vertical rod 1222 can be adjusted on the other hand, so as to ensure that the plurality of vertical rods 1222 are neatly arranged in the same straight line, thereby improving the aesthetics.

[0096] refer to Figure 7 , Figures 14 to 16 In some embodiments, a side opening is provided on the lateral outer side of the receiving slot 1126 (e.g., a C-shaped slot), and the bracket 112 further includes a plurality of handrail mounting plates 1127 vertically spaced in the side opening and having mounting holes 1129; each adjustment gasket 113 is provided between each handrail mounting plate 1127 and the vertical rod 1222; and the interval G between adjacent handrail mounting plates 1127 allows the adjustment gasket 113 to be installed. In this way, the adjustment gaskets 113 can be conveniently provided between the vertical rod 1222 and each handrail mounting plate 1127.

[0097] The present application realizes that although the assembly of the handrail assembly 120 and the support unit 110 can be conveniently installed by placing it outside the support unit 110, it is not conducive to improving space utilization and may even exceed the limit of the locomotive. Therefore, in the present technical solution, the installation structure of the handrail assembly 120 is hidden in the support unit 110. However, there are still problems such as the installation status cannot be observed and the height of the installation surface cannot be adjusted. Therefore, the present invention forms a box-shaped structure with the receiving groove 1126 for installing the handrail on the support unit 110 and multiple (for example, two) handrail mounting plates 1127, and leaves sufficient installation gaps between the multiple handrail mounting plates 1127. The gap allows the insertion of adjustment gaskets 113 to achieve the leveling of each handrail mounting surface, and the multiple handrail mounting plates 1127 can be individually installed with adjustment gaskets 113, so that the verticality of the handrail to the horizontal plane can be adjusted by adding or removing the adjustment gaskets 113.

[0098] refer to Figures 11 to 13 In some embodiments, the handrail bar assembly 120 includes a plurality of handrail bar units 122 and a plurality of connecting units 124 arranged in the longitudinal direction, and each connecting unit 124 is detachably connected between two adjacent handrail bar units 122; the handrail bar unit 122 is a welded frame structure and has a plurality of vertical rods 1222. The handrail bar assembly 120 has a high reuse rate with the handrail bar unit 122 and the connecting unit 124 as the basic assembly unit. A suitable number of handrail bar units 122 and connecting units 124 can be selected according to demand to assemble into a modular handrail bar assembly 120. The present invention designs the handrail bar unit 122 as a welded frame structure, and each welding point of the frame structure is firmly connected without relative displacement, which can avoid the problem of easy instability of the handrail bar assembly caused by the use of fasteners; and when disassembling the handrail bar assembly 120, the disassembly and assembly between the handrail bar unit 122 and the connecting unit 124 is mainly carried out, which can reduce the disassembly and assembly workload and improve the disassembly and assembly efficiency. In addition, since the handrail bar unit 122 is a welded structure, the spacing between the plurality of vertical bars 1222 is not adjustable, and thus the handrail bar assembly 120 can be used as a positioning tool to assist in the assembly of the support unit 110 .

[0099] In some embodiments, the assembly method of the support unit 110 may include the following steps:

[0100] The plurality of brackets 112 and the plurality of connecting beams 114 are alternately arranged in the longitudinal direction and preliminarily connected in sequence;

[0101] Adjust the positions of the multiple brackets 112 and the multiple connecting beams 114 so that the positions of the multiple brackets 112 correspond to the positions of the multiple vertical rods 1222 one by one; that is, use the handrail assembly 120 as a positioning tool to adjust and position the brackets 112;

[0102] The bracket 112 and the connecting beam 114 are finally fixed to complete the assembly of the supporting unit 110 .

[0103] In a specific embodiment, the assembly method is as follows: first, a plurality of brackets 112 are arranged at a certain interval, the connecting beam 114 is pre-installed, and the mounting screws are fixed without torque. Next, the vertical rod 1222 of the handrail assembly 120 is installed on the bracket 112, and the handrail assembly 120 is used as a positioning tool. After the bracket 112 is fine-tuned to adapt to the handrail assembly 120, the mounting screws of the connecting beam 114 and the bracket 112 are tightened to complete the assembly of the support unit 110.

[0104] refer to Fig.11 , Fig.12 , Fig.19 The handrail bar assembly 120 of the present invention has the following characteristics: it can adapt to the change of the length of the locomotive as the size of the handrail bar unit 122 increases or decreases; it can adapt to the change of the length of the locomotive as the number of handrail bar units 122 increases or decreases; it can adapt to the change of the length of the locomotive as the size of the connecting unit 124 increases or decreases; the handrail bar unit 122 and the connecting unit 124 have obvious commonalities and can be used as modular parts and replicated in batches. The shape and structure of the handrail bar units 122 located on the far sides can be different from the handrail bar units 122 located in the middle to adapt to the situation on both sides.

[0105] In some embodiments, in order to achieve a tight connection between the handrail bar assembly 120 and the supporting unit 110, the handrail bar unit 122 is a welded structure within a length of 3000 mm, multiple handrail bar units 122 are as identical as possible, and the distance between two adjacent vertical rods 1222 of the handrail bar unit 122 is 1000 mm.

[0106] refer to Fig.17 and Fig.18 In some embodiments, the vertical rod 1222 includes a rod body 1221 (e.g., a round tube) with a circular cross-section, and the lower area 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, and a plurality of mounting holes are formed on the mounting plate 1223. In this way, the curved surface of the rod body 1221 can be converted into a plane, which is conducive to achieving a planar connection between the vertical rod 1222 and the support unit 110, and ensuring the effectiveness and stability of the connection. The mounting plate 1223 can be further welded to the blocking portion 1225 to improve the stability of the installation. The blocking portion 1225 can assist the vertical rod 1222 in transitioning from a curved surface to a plane, creating conditions for achieving a planar installation of the vertical rod 1222.

[0107] In a specific embodiment, half of the portion of the round tube after passing through the baffle is removed, and the remaining half of the tube is welded to the mounting plate and then welded to the baffle. Two threaded holes for mounting the handrail assembly are left on the mounting plate, and the two threaded holes are arranged vertically for screwing the handrail assembly 120 to the external support structure. The connection points of the handrail assembly 120 and the support unit 110 are arranged vertically, which can greatly improve the stability of the handrail assembly 120 after installation.

[0108] The blocking portion 1225 and the mounting plate 1223 are perpendicular to each other, and 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 vertical welding structures, the lower plane of the blocking portion 1225 is pressed on the upper plane of the receiving groove 1126, and the mounting plate 1223 is pressed on the mounting plane inside the handrail mounting plate 1127, and then fixed by two sets of vertically arranged handrail fasteners 111. Through this technical solution, not only the horizontal planes of the two mounting structures are fitted, but also the two vertical mounting planes are fitted, and then fixed by fasteners, the original single-plane close-fitting structural form of the handrail can be upgraded to two sets of mutually perpendicular planes close-fitting, which can greatly improve the stability of the handrail assembly 120 after installation.

[0109] refer to Fig.12 and Fig.19 In some embodiments, the handrail bar unit 122 includes a frame and a plurality of vertical rods 1222 welded to the frame and arranged at predetermined intervals in the longitudinal direction. X represents the predetermined interval, X1 represents the longitudinal distance between the first side edge of the frame and the vertical rod 1222 closest to it, X2 represents the longitudinal distance between the second side edge of the frame and the vertical rod 1222 closest to it, and X3 represents the longitudinal distance between two adjacent frames, and the formula: X=X1+X2+X3 is satisfied. Through such an arrangement, it can be ensured that the distance between the vertical rod 1222 at the tail end of the previous handrail bar unit 122 and the vertical rod 1222 at the head end of the next handrail bar unit 122 is the same as the distance between two adjacent vertical rods 1222 in each handrail bar unit 122. In this way, the plurality of vertical rods 1222 of the handrail bar assembly 120 are evenly arranged at the same interval, so as to adapt to the plurality of brackets 112 arranged at the same interval, and ensure that the handrail bar assembly 120 can be properly installed and matched to the support unit 110.

[0110] refer to Fig.12In some embodiments, the frame includes a bent surrounding rod 1224 and a longitudinally extending straight rod 1226. The two ends of the surrounding rod 1224 are respectively welded to two vertical rods 1222 located on both sides of the plurality of vertical rods. The straight rod 1226 is welded between two adjacent vertical rods 1222. The surrounding rod 1224 can have four bending angles and have multiple longitudinal extension parts and vertical extension parts. Through such an arrangement, the amount of welding can be reduced, and the straight rod 1226 can be set as short as possible to reduce the manufacturing cost. In a specific embodiment, the main body of the handrail rod unit 122 is welded by a surrounding rod 1224, two straight rods 1226, and three vertical rods 1222. The surrounding rod 1224 is bent 90 degrees 4 times.

[0111] refer to Figures 19 to 26 In some embodiments, connectors 1228 are provided on both longitudinal sides of the handrail bar unit 122, and the connectors 1228 form matching grooves 1229. The two ends of the connection unit 124 are respectively fixed to the matching grooves 1229 of the two handrail bar units 122 by fixing members 126. Insertion portions 1242 for inserting into the matching grooves 1229 are formed at the two ends of the connection unit 124, and a step is formed at the connection between the insertion portion 1242 and the main body of the connection unit 124 so as to be closely matched with the matching grooves 1229. By inserting into the matching grooves 1229 and fixing by fixing members 126, the connection reliability between the handrail bar unit 122 and the connection unit 124 can be ensured. The connector 1228 can be welded to the handrail bar unit 122.

[0112] In some embodiments, the fixing member 126 includes a screw 1262 and a nut 1264, and the two opposite groove walls of the matching groove 1229 are respectively provided with a through hole h1 and a regular hexagonal hole h2 matching the nut 1264. The regular hexagonal hole h2 can limit the position of the nut 1264 to prevent the nut 1264 from rotating, so that during installation, there is no need to operate the nut 1264 with a wrench. In addition, the nut 1264 can be embedded in the regular hexagonal hole h2 to improve the aesthetics and safety.

[0113] In some embodiments, the position of the end of the connecting unit 124 in the matching groove 1229 is adjustable in the longitudinal direction, so as to accommodate the installation error between adjacent handrail bar units 122. The adjustment margin can be provided by setting the size of the through hole h1 and the regular hexagonal hole h2 larger than the size of the screw 1262 and the nut 1264, respectively.

[0114] In a specific embodiment, the connection unit 124 uses M8X30 hexagon socket round head screws and M8 standard nuts, and is connected to the connection piece 1228 with a large gasket, so as to achieve the connection between adjacent handrail rod units 122. In theory, the number of handrail rod units 122 can be increased infinitely to complete the handrail assembly of the whole vehicle. A φ13mm through hole is provided on the A side of the connection piece 1228, and a regular hexagonal hole is provided on the B side. The side length of the regular hexagonal hole is slightly longer than the side length of the M8 nut. A groove is provided in the middle of the connection piece 1228 to match the end of the connection unit 124, and the distance between the two sides of the groove is slightly larger than the end of the connection unit 124. The two ends of the connection unit 124 are semicircular in shape, which facilitates the axial movement between the end and the connection piece 1228, and has a beautiful appearance. Both ends of the connection unit 124 have a φ11mm through hole. The φ13mm through hole on the connector 1228 and the φ11mm through hole at the end of the connecting unit 124 are used in conjunction with the M8X30 screw and the M8 nut, so that the assembly connection between the adjacent handrail rod units 122 makes up for the installation error at the production site. The regular hexagonal hole is opened on the B side of the connector, which directly acts as a "wrench" when installing the fastener. Only an M8 hexagonal wrench is needed to complete the handrail assembly, avoiding the trouble of using two wrenches for installation; as the screw is tightened, the nut penetrates into the regular hexagonal hole on the B side, and the outer side of the nut is lower than the outer plane on the B side of the connector, which can effectively prevent the exposed head of the fastener from causing damage to the driver and passengers.

[0115] refer to Fig. 27 and Fig.28 In some embodiments, the side trim 130 includes a plate body 132 and a transition piece 134 fixed to each other by fasteners, the transition piece 134 is fixed to the connecting beam 114 and has a through hole 1342, and the plate body 132 is located on the lateral outer side of the transition piece 134 and has a hook 1322 passing through the through hole 1342. By setting the hook 1322, on the one hand, the hook 1322 can be used to hook the transition piece 134 to limit the relative position of the transition piece 134 and the plate body 132, limit the vertical, horizontal and longitudinal movable space of the plate body 132, and prevent the plate body 132 from being separated from the transition piece 134; on the other hand, when installing the side trim 130, the transition piece 134 can be first fixed to the support unit 110, and then the plate body 132 can be hung on the transition piece 134 by the hook 1322. At this time, the operator can easily and effortlessly adjust the position of the plate body 132, and after the position is adjusted, the plate body 132 and the transition piece 134 are connected by fasteners to complete the installation of the side trim 130. In this way, one operator can independently complete the position adjustment and installation of the side trim 130.

[0116] refer to Fig.36 and Fig.37In some embodiments, the integrated side suspension module 100 further includes a display light mounting profile 160, which covers the lateral outer side of the side trim 130 to prevent the hook 1322 from falling out of the through hole 1342. When the plate 132 moves outwardly relative to the transition piece 134 by a large distance, the hook 1322 on the plate 132 may fall out of the through hole 1342. The present invention sets the display light mounting profile 160 to cover the lateral outer side of the side trim 130 to limit the lateral outward movement distance of the plate 132, thereby preventing the hook 1322 from falling out of the through hole 1342, and ensuring that the hook 1322 can always be inserted into the through hole 1342. Therefore, even if the fastener between the plate 132 and the transition piece 134 is loosened, the plate 132 will be hung on the transition piece 134 through the cooperation of the hook 1322 and the through hole 1342 and will not fall off, thereby preventing the side trim 130 from falling off from the support unit 110. The transition piece 134 may be securely fixed to the support unit 110 by means of a locking fastener (eg, a locking nut or a double nut).

[0117] refer to Fig.35 In some embodiments, the hook 1322 includes a vertical section s1, a transverse section s2, and an inclined section s3 that smoothly transition in sequence. The transverse section s2 extends from the lower end of the vertical section s1 to the transverse inner side. The lower end of the inclined section s3 is inclined to the transverse inner side relative to the upper end. The hook 1322 configured in this way can, on the one hand, be well joined to the plate body 132 through the vertical section s1 and be easily welded thereto. On the other hand, the relative positions of the plate body 132 and the transition piece 134 in multiple directions can be well restricted to prevent them from falling off. On the other hand, the hook 1322 can be easily hung in the through hole 1342, which is convenient for assembling the side trim 130 itself and installing it on the support unit 110.

[0118] The transverse section s2 has a length L, and an inclination angle θ is formed between the inclined section s3 and the transverse section s2. The values ​​of the length L and the inclination angle θ can be set according to actual conditions to ensure the anti-slip effect of the hook 1322 and to ensure that the hook 1322 can be easily hung in the through hole 1342. In the embodiment of the present invention, the transverse distance between the display light installation profile 160 and the side trim 130 is less than the length L of the transverse section s2, thereby preventing the hook 1322 from slipping out of the through hole 1342 and ensuring the reliability of the installation of the side trim 130. The display light installation profile 160 can cover the transverse outer side of the upper part of the side trim 130.

[0119] refer to Fig.36 and Fig.37In some embodiments, the handrail assembly 120 is fixed to the bracket 112 by the handrail fastener 111, and the side trim 130 covers the lateral outer side of the handrail fastener 111 to prevent it from loosening. The installation direction of the handrail fastener 111 is set in the lateral direction, and its end is located on the lateral outer side of the support unit 110. The side trim 130 covers the outer side of the end of the handrail fastener 111 to limit it, thereby preventing the handrail fastener 111 from loosening. In some embodiments, the display light mounting profile 160 is pressed on the corridor floor 140. Under the gravity of the display light mounting profile 160 and the display light mounted thereon, the display light mounting profile 160 applies downward pressure to the corridor floor 140 to prevent it from loosening.

[0120] In an embodiment of the present invention, the installation of the handrail assembly 120 is prevented from falling off by the side trim 130, and the installation of the side trim 130 and the corridor floor 140 is prevented from falling off by the display light mounting profile 160. The present invention arranges and combines multiple functional components of the integrated side suspension module 100 in an orderly manner, and utilizes the structural characteristics of each component to form a progressive interlocking anti-falling chain. The anti-falling is achieved in the progressive installation structure, which can improve the safety and reliability of the entire module, prevent deformation during the overall disassembly and assembly of the side suspension module, and achieve quick disassembly and assembly of the entire side suspension module. It can save the need for separate anti-falling for each installation component, and save installation space and materials. The installation of each component in the side suspension module is interlocking and compact in structure, creating conditions for completing the arrangement of each component in a limited space. Through the application of the interlocking anti-falling structure, the amount of anti-loosening fasteners is reduced, the product cost is reduced, and the disassembly and assembly efficiency is improved.

[0121] The display light installation profile 160 can be fixed by anti-loosening fasteners (such as anti-loosening nuts or double nuts) to achieve anti-loosening, providing reliable protection for the entire interlocking anti-loosening chain. The display light installation profile 160 can be fixed on the vertical rod 1222 of the handrail assembly 120.

[0122] In some embodiments, the position of the plate 132 relative to the transition piece 134 in the vertical and lateral directions is adjustable, and the position of the transition piece 134 relative to the connecting beam 114 in the longitudinal direction is adjustable. Figures 27 to 30 and Fig.34The plate body 132 has a first slideway 1324 arranged in the vertical direction, and a first fastener 1362 (such as a T-bolt) is adjustably arranged in the first slideway 1324. The plate body 132 is vertically adjustable relative to the transition piece 134 through the first slideway 1324 and the first fastener 1362. The transition piece 134 may have a second slideway 1344 arranged in the longitudinal direction, and the integrated side suspension module 100 includes a second fastener 1366 (such as a T-bolt) adjustably arranged in the second slideway 1344 and connected to the support unit 110. The transition piece 134 is longitudinally adjustable relative to the support unit 110 through the second slideway 1344 and the second fastener 1366. In this way, the side trim 130 can be adjusted in the vertical and longitudinal directions. In addition, the side trim 130 can be adjusted in the transverse direction by arranging a gasket between the plate body 132 and the transition piece 134. By providing the position adjustability of the side trim 130 in multiple directions, it can adapt to installation with large errors, which is conducive to adjusting multiple side trims 130 to mutually flush positions, ensuring that the side trim 130 has a neat and uniform appearance, and improving the aesthetics of the motorcycle. The side trim 130 can have multiple first slides 1324 arranged at intervals in the longitudinal direction, and accordingly, the number of the first fastener 1362, the transition piece 134 and the second slide 1344 is also multiple.

[0123] Those skilled in the art should understand that the manner of achieving adjustable relative positions of the plate body 132 and the transition piece 134 and adjustable relative positions of the transition piece 134 and the connecting beam 114 is not limited to the manner of using the cooperation of slideways and fasteners, but may also adopt the manner of using the cooperation of multiple connecting holes arranged along a specific direction and fasteners, the manner of using long holes arranged along a specific direction and fasteners, the manner of using multiple slots arranged along a specific direction and protrusions, the manner of using guide rails and sliders, and the like.

[0124] refer to Fig. 27 , Fig.31 and Fig.32 In some embodiments, the plate body 132 is a bent component and includes a main area 1321 and a lower area 1323. The main area 1321 extends vertically and longitudinally, and the lower area 1323 is inclined laterally inward relative to the main area 1321. A bend B1 is set in the middle and lower part of the plate body 132 to form the main area 1321 and the lower area 1323. Through the bending design, the rigidity of the middle part of the plate body 132 can be improved while preventing the side trim panel 130 from exceeding the locomotive limit after installation. The plate body 132 can be made of carbon steel skin with a thickness of less than 2 mm and pressed on three sides into a rectangular return bend. A bend B2 is set at the bottom edge of the plate body 132 to improve the peripheral rigidity of the thin plate. It can be Fig.31 The circled portion is laser welded to avoid thermal deformation affecting the flatness of the plate 132. It should be noted that the plate 132 is too long to be fully displayed. Fig.31 The dotted line that cuts off the plate body 132 indicates that a portion of the plate body 132 is cut off and hidden.

[0125] refer to Fig.28 , Fig.29 and Fig.30 The first slideway 1324 is provided in the main body region 1321, the lower region 1323 is further provided with a third slideway 1326, a third fastener 1364 (such as a T-bolt) is adjustably provided in the third slideway 1326, the transition piece 134 is further fixed to the plate body 132 by the third fastener 1364, and the projection of the third slideway 1326 on a plane parallel to the main body region 1321 extends vertically. By adding the third slideway 1326 and the third fastener 1364, the connection reliability between the transition piece 134 and the plate body 132 is further improved.

[0126] refer to Fig.28 and Fig.33 In some embodiments, the plate body 132 is welded (for example, broken welded) with a support plate 1328, the first slideway 1324 and the third slideway 1326 are welded to the support plate 1328, and multiple welding locations of the support plate 1328 and multiple welding locations of the first slideway 1324 and the third slideway 1326 are arranged alternately. The first slideway 1324 and the third slideway 1326 are not directly welded to the plate body 132, but are transitioned through the support plate 1328. Such a technical solution can not only improve the rigidity of the corresponding area of ​​the plate body 132, but also avoid deformation of the plate body 132 due to welding by staggering the multiple welding locations of the support plate 1328 on the plate body 132 and the multiple welding locations of the first slideway 1324 and the third slideway 1326 on the support plate 1328, thereby providing high-quality technical support for the rigidity and flatness of the side trim 130 and the installation, and meeting the aesthetic requirements of the side trim 130. The support plate 1328 may have a folded edge s, and the folded edges s on the upper and lower sides of the support plate 1328 are respectively welded to the return bend of the plate body 132 to improve the rigidity of the middle part of the thin plate. Fig.33 The large circle indicates the weld bead portion of the support plate 1328 on the plate body 132, and the small circle indicates the weld bead portion of the first slideway 1324 and the third slideway 1326 on the support plate 1328. The weld bead portion of the support plate 1328 is arranged alternately with the weld bead portions of the first slideway 1324 and the third slideway 1326 to avoid weld concentration, disperse the heat effect caused by welding, and prevent welding deformation. In addition, the width of the support plate 1328 can be greater than the width of the first slideway 1324 and the third slideway 1326 by more than 20 mm to further avoid weld concentration and welding deformation.

[0127] like Fig.34As shown, the transition piece 134 can be made of angle steel to ensure sufficient strength, and the transition piece 134 can have a vertical portion and an inclined portion corresponding to the main area 1321 and the lower area 1323. The transition piece 134 is welded with the second slideway 1344 to ensure the connection strength. The transition piece 134 has a plurality of matching holes 1346 that are matched with the first fastener 1362 and the third fastener 1364 respectively.

[0128] The two installation methods of the side trim plate 130 of the present invention relative to the support unit 110 are as follows:

[0129] The first method is to install the panel 132 and the transition piece 134 by using the first slideway 1324 and the first fastener 1362, and then connect the transition piece 134 to the support unit 110 by using the second slideway 1344 and the second fastener 1366, so that the installation of the side trim 130 can be completed smoothly.

[0130] The second method is to be performed when there is an error in the installation matching dimensions and the installation space is insufficient. The connection between the plate body 132 and the transition piece 134 is released, and the transition piece 134 is first installed on the support unit 110 through the second slide 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 plate body 132 is hung on the transition piece 134 through the hook 1322; after that, one operator can independently complete the three-way size adjustment and installation of the side trim 130.

[0131] The situation that the on-site matching dimensions are accurate is often just an ideal. In most installation processes, it is inevitable that the side trim installation position will be slightly adjusted. At this time, the role of the hook 1322 and the perforation 1342 in this technical solution is fully demonstrated. After the plate body 132 is hung on the transition piece 134, the operator can make three-way adjustments to ensure that the side trim is installed with a uniform and neat appearance.

[0132] In order to highlight the decorative function of the side trim 130, the first slide 1324, the first fastener 1362, the third slide 1326, the third fastener 1364, the hook 1322 and other structures are arranged on the installation side of the side trim 130. After the side trim 130 is installed, the various devices to be protected are hidden, and the various appearances of different devices are transformed into the unified appearance of the side trim 130, thereby realizing the most important functions of the side trim 130: decoration and protection.

[0133] refer to Fig.38In some embodiments, the display light mounting profile 160 extends in the longitudinal direction and includes a profile body 162 and a profile lower region 164. The lateral inner side of the profile body 162 forms a profile mounting portion 161 for mounting the display light mounting profile 160 on a component to be mounted, the lateral outer side of the profile body 162 forms a display light mounting groove 163, and the lateral middle portion of the profile body 162 forms a wiring cavity 165 that is connected to the display light mounting groove 163 and the lateral inner space of the profile body 162 through a wire hole 167. The display light mounting profile 160 is mounted on the handrail bar assembly 120.

[0134] The profile mounting portion 161 may include a slideway for engaging with a fastener. Fig.36 The integrated side suspension module 100 also includes a profile mounting member 166, and the display light mounting profile 160 is mounted on the vertical rod 1222 of the handrail assembly 120 by the cooperation of the fasteners arranged on the slideway and the profile mounting member 166. The profile mounting member 166 may include an arc-shaped embracing portion and straight extension portions extending from both sides of the arc-shaped embracing portion, and the straight extension portions are formed with mounting holes that cooperate with the fasteners. The number of display light mounting grooves 163 may be one or more. The display light mounting groove 163 is used to install a display light, and the display light may be configured to indicate different states of the locomotive by displaying lights of different colors and / or different intensities, such as low power, charging, and full battery. A clamping portion 168 for fixing the display light may be formed on the wall of the display light mounting groove 163, and the clamping portion 168 may be in the form of a protrusion, a clamping groove, a clamping ring, a clamping claw, etc. The wiring cavity 165 is used for wiring. The wire hole 167 allows the electrical connection wires of the display light to extend from the lateral outer side of the profile body 162 to the lateral inner side and be hidden.

[0135] refer to Fig.37 and Fig.38 The lower area 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 area 164 of the profile can firstly block the possible installation error of the side trim 120, and secondly provide an anti-dropping effect for the side trim 130. In addition, the lower area 164 of the profile can also form a fluorescent sticker installation portion 169 (such as a fluorescent sticker installation groove), making the function of the display light installation profile 160 more diversified and achieving a lightweight effect.

[0136] The display light mounting profile 160 of the present invention realizes the concept of functional integration. It not only completes its own installation and the installation of the charging display light, but also plays a decorative role. One side of the two sides of the corridor floor is the mechanical room on the vehicle, and the other side is the handrail assembly, but the protection range of the handrail is limited. The corridor floor will slip in winter and rainy seasons. The display light mounting profile 160 installed below the handrail assembly and protruding above the corridor floor has the function of waistline decoration for the whole vehicle and the characteristics of a skirting line for the corridor, which can provide necessary protection for drivers and passengers. In an embodiment of the present invention, the display light mounting profile 160 has the characteristics of multi-functional integration such as light strip installation, wiring, threading, self-installation, protection, anti-slip, and external decoration.

[0137] In some embodiments, the assembly method of the integrated side suspension module 100 includes the following steps:

[0138] The handrail assembly 120 is fixed to the lateral outer side of the support unit 110 through the handrail fastener 111;

[0139] The side trim 130 is fixed to the support unit 110 so that the side trim 130 covers the lateral outer side of the handrail fastener 111 to prevent it from loosening; wherein the side trim 130 includes a plate body 132 and a transition piece 134 fixed to each other by the fastener, the transition piece 134 is fixed to the support unit 110 and has a through hole 1342, and the plate body 132 is located on the lateral outer side of the transition piece 134 and has a hook 1322 penetrated through the through hole 1342;

[0140] Fix the corridor floor 140 to the upper side of the support unit 110;

[0141] The display light mounting profile 160 is fixed to the handrail assembly 120 by anti-loosening fasteners, so that the display light mounting profile 160 is pressed on the corridor floor 140 and covers the lateral outer side of the side trim 130 to prevent the hook 1322 from escaping from the through hole 1342.

[0142] According to the above installation sequence, a solution is finally formed in which the multi-layer installation structure in the side suspension module is cleverly coordinated and installed layer by layer in a progressive manner, so that the subsequent installation structure can prevent the previous installation structure from falling off, forming a progressive interlocking anti-falling chain. Once the interlocking anti-falling chain is formed in the side suspension module, even if the fasteners of the system components are loose or even fall off, it will not cause the entire module to collapse and fail. The progressive interlocking anti-falling chain realizes the close coordination of the various components in the side suspension module, creating favorable conditions for the overall quick disassembly and assembly of the side suspension module.
