[0038] like Figures 1 to 5As shown, this embodiment provides an integrated supply module for rear chassis components and a rear floor, including a rear chassis component 12, a rear floor structure 11, and a packaging structure 2. The rear chassis component 12 includes a tire assembly 121, a powertrain 122, a suspension system 123, a transmission system 124, a braking system 125, and a suspension system 126. The rear floor structure 11 has multiple mounting areas, and the rear chassis component 12 is attached to the corresponding mounting area to assemble with the rear floor structure 11 to form a rear chassis assembly 1. The packaging structure 2 has a loading space 23, which is defined by a base plate 21 and a plurality of columns 22 arranged circumferentially around the base plate 21. The rear chassis assembly 1 is placed in the loading space 23 and supported by the base plate 21. The columns 22 are provided with a first limiting device 24, which at least partially abuts against or is connected to the rear floor structure 11 to restrict the movement of the rear chassis assembly 1. In this way, the dispersed rear chassis components 12 can be integrated with the rear floor structure 11 and the packaging structure 2 into a compact, functional, and easy-to-assemble modular assembly, allowing for more efficient use of space when transporting in a modular manner. This not only takes into account the spatial layout, connection stability, and safety of each component, but also effectively reduces transportation and warehousing costs. At the same time, the integrated rear chassis components 12 and rear floor structure 11 can be directly applied or simply assembled for final assembly after reaching the destination, thereby significantly shortening the production cycle and eliminating assembly errors, ensuring the overall performance of the vehicle.

[0039] For example, such as Figures 2 to 5As shown, the rear floor structure 11 is a closed frame structure formed by two longitudinal beams 111 and two transverse beams 112 in the horizontal direction. At the same time, as the load-bearing structure of the rear chassis component 12, it has attachment points for components such as the suspension system 123, transmission system 124, and suspension system 126. The specific arrangement positions can refer to the conventional attachment point positions of the rear chassis assembly 1. The attachment methods include, but are not limited to, bolt connection, welding, and snap-fit ​​connection to ensure a firm connection between each rear chassis component 12 and the rear floor structure 11. Specifically, the rear chassis components 12 and the rear floor structure 11 can be assembled according to vehicle standards. The suspension system 123 includes a rear suspension assembly 1231, a left suspension assembly 1232, and a right suspension assembly 1233. The powertrain 122 is connected to the rear floor structure 11 via the suspension system 123. The transmission system 124 includes a left driveshaft assembly 1241 and a right driveshaft assembly 1242 connected to the powertrain 122. The suspension system 126 includes a stabilizer bar assembly 1261 and a stabilizer bar connecting rod assembly. 1262, rear upper linkage assembly, 1263, rear lower control arm assembly, 1264, front lower control arm assembly, 1265, front upper control arm assembly, 1266, shock absorber assembly, 1267, spring assembly, and height sensor 1269; braking system 125 and tire assembly 121 are connected to powertrain 122 and rear floor structure 11 via suspension system 126 and transmission system 124; simultaneously, all rear chassis components 12 are interconnected via wiring harness and sensor assembly 127 to complete the assembly of rear chassis assembly 1. In this way, the assembled rear chassis assembly 1 can be directly applied or, after simple assembly, applied to final assembly operations upon reaching its destination, thereby significantly shortening the production cycle, eliminating assembly errors, and ensuring the overall performance of the vehicle. The packaging structure 2 includes a base plate 21 and four uprights 22 arranged circumferentially around the base plate 21. The four uprights 22 are respectively located at the four corners of the base plate 21 and are fixed to the upper surface of the base plate 21 by bolts or welding. Each upright 22 is provided with a first limiting device 24. The first limiting device 24 can be a connecting device that is rigidly connected by plugging, snapping, or bolting, or a connecting device that is softly connected by wrapping and binding by ropes, straps, etc., or it can be a clamp or claw with clamping function that can clamp the longitudinal beams 11 of the rear floor structure 11. A clamping device that performs a clamping action at one end and clamps it is sufficient to restrict the movement and rotation of the rear floor structure 11. In this way, the assembled rear chassis assembly 1 is placed in the loading space 23 by a forklift or crane. The bottom of the rear chassis assembly 1 is supported on the base plate 21 by the tire assembly 121. The four ends of the two longitudinal beams 111 of the rear floor structure 11 correspond to the four columns 22 respectively. The first limiting device 24 abuts against or connects to the four ends, thereby restricting the movement of the rear chassis assembly 1 and fixing the rear chassis assembly 1 in the loading space 23.

[0040] Furthermore, since the longitudinal beams 111 of the rear floor structure 11 have a width that is relatively wider at the front and relatively narrower at the rear in the horizontal transverse y direction, therefore, as Figure 1 As shown, the four columns 22 can be designed such that the distance between the two columns 22 on the front side of the horizontal longitudinal x is wider, and the distance between the two columns 22 on the rear side of the horizontal longitudinal x is narrower, so as to adapt to and ensure the effective connection between the first limiting device 24 and the rear floor structure 11 and the columns 22.

[0041] In some embodiments, such as Figure 1 and Figure 5 As shown, the packaging structure 2 also includes a second limiting device 25, which is located on the base plate 21. This second limiting device 25 can be a limiting structure that abuts against the four horizontal sides of the tire assembly 121, a connecting device that wraps and binds the tire assembly 121 using ropes, straps, or other means, or a clamping device such as a clamp or gripper that has a clamping function and can clamp the tire assembly 121 of the rear chassis component 12. Thus, by abutting against or connecting to the tire assembly 121, the second limiting device 25, in conjunction with the first limiting device 24, further restricts the movement and rotation of the rear chassis assembly 1. It is understood that there are two tire assemblies 121 in the rear chassis assembly 1; therefore, two sets of second limiting devices 25 can be correspondingly provided. Each set of second limiting devices 25 abuts against or connects to one of the two tire assemblies 121, ensuring reliable fixation of the rear chassis assembly 1 within the loading space 23.

[0042] The first limiting device 24 and the second limiting device 25 will be described in detail below to provide a limiting and fixing method that is simple in structure, easy to use, and easy to install and remove.

[0043] In some embodiments, such as Figure 1 and Figure 5As shown, the first limiting device 24 includes a clamping assembly 241, which is mounted on the column 22 corresponding to the longitudinal beam 111 of the rear floor structure 11, and has a switchable first state and a second state relative to the column 22. In the first state, the actuating end of the clamping assembly 241 presses against the upper end face of the longitudinal beam 111 to restrict the rear chassis assembly 1 from moving in the vertical direction z. In the second state, the actuating end of the clamping assembly 241 disengages from the longitudinal beam 111 and does not interfere with the rear floor structure 11. The rear chassis assembly 1 moves in and out of the loading space 23; the second limiting device 25 includes a first limiting block 251 and a second limiting block 252, which are fixedly connected to the base plate 21. The fixed connection method includes, but is not limited to, bolt connection or welding; when the rear chassis assembly 1 is placed in the loading space 23, the first limiting block 251 and the second limiting block 252 abut against the front and rear sides of the tire assembly 121 in the circumferential direction, respectively, to limit the rear chassis assembly 1 from moving in the horizontal longitudinal direction x. With the above settings, the first limiting block 251 can be switched to the second state. Then, the rear chassis assembly 1 is transported by a crane or forklift and placed between the first limiting block 251 and the second limiting block 252 to limit the movement of the rear chassis assembly 1 in the horizontal longitudinal direction (x). The first limiting block 251 is then switched to the first state, and the clamping assembly 241 presses the rear chassis assembly 1 against the base plate 21 in the vertical direction (z), restricting its movement in that direction. The clamping force is then transmitted downwards to the tire assembly 121, utilizing the friction between the tire assembly 121 and the base plate 21 to restrict the rear chassis assembly 1's movement in the horizontal lateral direction (y), thus fixing the rear chassis assembly 1 within the loading space 23. It is understood that the clamping assembly 241 can be a clamping device, and its specific structure for performing the clamping / disengagement action through state switching can be referenced from conventional technologies in related fields, and will not be elaborated here.

[0044] It is also understood that, in the above embodiments, four clamping components 241 are provided, respectively disposed on the four columns 22, which can provide uniform and effective clamping to the ends of the four longitudinal beams 111 of the rear floor structure 11. In other embodiments, since the rear chassis assembly 1 is supported on the floor 21 by the tire assembly 121, the number of clamping components 241 is at least two, and the two clamping components 241 are respectively located at both ends of the horizontal longitudinal x of one of the longitudinal beams 111 of the rear floor structure 11, or at the front end of one of the longitudinal beams 111 and the rear end of the other longitudinal beam, so that the tire assembly 121 is balanced in the horizontal longitudinal x direction, ensuring effective clamping in the vertical z direction.

[0045] In some embodiments, such as Figure 1 and Figure 5As shown, the second limiting device 25 also includes at least two third limiting blocks 253, which are fixedly connected to the base plate 21. The fixed connection method includes, but is not limited to, bolt connection or welding. In this embodiment, there are two third limiting blocks 253. When the rear chassis assembly 1 is placed in the loading space 23, the two third limiting blocks 253 abut against the left and right sides of the tire assembly 121 axially. In this way, the movement of the rear chassis assembly 1 in the horizontal lateral y can be restricted, and the reliability of the limiting and fixing of the rear chassis assembly 1 in the horizontal lateral y can be further improved. It is understood that there are two tire assemblies 121 in the rear chassis assembly 1. Therefore, the two third limiting blocks 253 can be respectively disposed on the left and right sides of one of the tire assemblies 121, or one of the third limiting blocks 253 can be disposed on the left side of one of the tire assemblies 121 and the other third limiting block 253 can be disposed on the right side of the other tire assembly 121. In this case, the two third limiting blocks 253 can be located on the opposite inner sides of the two tire assemblies 121 in the horizontal lateral direction y, or as in this embodiment. Figure 1 and Figure 5 The tires shown are located on opposite sides of the two tire assemblies 121 in the horizontal lateral direction y, which can restrict the movement of the rear chassis assembly 1 in the horizontal lateral direction y.

[0046] Furthermore, such as Figure 1 and Figure 5 As shown, the first limiting device 24 also includes a support rod 242, which is fixed to the column 22 and is arranged opposite to the clamping assembly 241 in the vertical direction z. When the clamping assembly 241 is in the first state, the longitudinal beam 111 is pressed between the clamping assembly 241 and the support rod 242. In this way, when the rear chassis assembly 1 is placed in the loading space 23, the longitudinal beam 111 can be supported and positioned by the support rod 242, which facilitates and ensures that the rear chassis assembly 1 is placed horizontally with the front and rear ends of the longitudinal beam 111 in the loading space 23. At the same time, since the horizontal lateral y-limiting fixation of the rear chassis assembly 1 is achieved by the third limiting block 253, the clamping assembly 241 of the first limiting device 24 does not need to provide a large downward pressure on the rear floor structure 11 to increase the friction between the tire assembly 121 and the floor 21. Therefore, the downward pressure height of the clamping assembly 241 in the first state can be slightly increased to reduce the force of the clamping action on the rear floor structure 11. It is understood that in this embodiment, the support rod 242 can be set only on the column 22 on the rear side of the horizontal longitudinal x, without interfering with the rear chassis assembly 1 entering and exiting the loading space 23 from the front side of the horizontal longitudinal x.

[0047] Since the rear chassis components 12 and the rear floor structure 11 are assembled according to vehicle standards, the assembled rear chassis assembly 1 can be moved via the tire assembly 121. Therefore, in some embodiments, such as Figure 1 , Figure 5 and Figure 6As shown, the first limiting block 251 is movably connected to the base plate 21 and has switchable third and fourth states relative to the base plate 21. In the third state, the first limiting block 251 abuts against the front side of the tire assembly 121 in the circumferential direction. In the fourth state, the first limiting block 251 and the tire assembly 121 are offset in the horizontal longitudinal direction (x). With the above settings, the first limiting block 251 can be switched to the fourth state, and then the rear chassis assembly 1 can be moved from the front side of the packaging structure 2 to abut against the second limiting block 252. Then, the first limiting block 251 can be switched back to the third state to achieve movement limitation of the rear chassis assembly 1 in the horizontal longitudinal direction (x). In this way, the rear chassis assembly 1 can be moved into the loading space 23 using the tire assembly 121, reducing the lifting / hoisting process of the rear chassis assembly 1 and further avoiding the risk of collision and deformation of the rear chassis assembly 1 caused by the lifting / hoisting process.

[0048] Specifically, such as Figure 1 , Figure 5 and Figure 6 As shown, the first limiting block 251 can be slidably connected to the base plate 21 to achieve state switching between the third and fourth states. In this embodiment, the base plate 21 has a groove 211 extending in the horizontal lateral direction y. The groove 211 has a first end 2111 and a second end 2112 distributed in the horizontal lateral direction y. The first limiting block 251 is slidably engaged with the groove 211, and a locking mechanism 2511 is provided between the first limiting block 251 and the groove 211. When the locking mechanism 2511 is unlocked, the first limiting block 251 can slide relative to the groove 211; when the locking mechanism 2511 is locked, the first limiting block 251 can be fixed on the base plate 21. When the first limiting block 251 moves to the first end 2111, the first limiting block 251 corresponds to the second limiting block 252 in the horizontal longitudinal direction x. At this time, the first limiting block 251 is in the third state relative to the base plate 21 and can abut against the front side of the tire assembly 121 in the circumferential direction, cooperating with the second limiting block. Block 252 limits the movement of the rear chassis assembly 1 in the horizontal longitudinal direction (x). When the first limiting block 251 moves to the second end 2112, the first limiting block 251 is offset from the second limiting block 252 in the horizontal longitudinal direction (x). At this time, the first limiting block 251 is in a fourth state relative to the base plate 21, which can avoid interfering with the movement of the rear chassis assembly 1 during placement. In this embodiment, the locking mechanism 2511 can be a bolted connection, that is, the first limiting block 251 slides along the slide groove 211 through the bolt. When the bolt is loosened, the first limiting block 251 can slide along the slide groove 211. When the first limiting block 251 slides to the designated position, the bolt is tightened to fix the first limiting block 251 on the base plate 21, thereby locking the first limiting block 251 in the corresponding state and ensuring the reliability of the limiting during transportation. Further, as Figure 6As shown, the first end 2111 of the slide groove 211 extends along any side of the horizontal longitudinal direction x to form a third end 2113. At this time, the slide groove 211 is F-shaped, and the first limiting block 251 can slide along the slide groove 211 between the first end 2111 and the third end 2113. In this way, the distance between the first limiting block 251 and the second limiting block 252 can be adjusted to accommodate tires of different sizes.

[0049] In other embodiments, the first limiting block 251 can also be rotatably connected to the base plate 21 to achieve state switching between the third state and the fourth state. In this embodiment, the base plate 21 has a receiving groove, and the first limiting block 251 is disposed in the receiving groove and is hinged to the base plate 21 at any end in the horizontal longitudinal direction x via a hinge structure. At this time, the first limiting block 251 can rotate around the hinge end. When the first limiting block 251 is in the third state relative to the base plate 21, the first limiting block 251 is configured to be able to rotate to extend and support in the receiving groove, and then abut against the front side of the tire assembly 121 in the circumferential direction, and cooperate with the second limiting block 252 to realize the movement limitation of the rear chassis assembly 1 in the horizontal longitudinal direction x. When the first limiting block 251 is in the fourth state relative to the base plate 21, the first limiting block 251 is configured to be able to fold and rotate to be stored in the receiving groove. At this time, the first limiting block 251 is offset from the second limiting block 252 in the horizontal longitudinal direction x, which can avoid interfering with the movement of the rear chassis assembly 1 during placement. It is understandable that the specific structure by which the first limiting block 251 unfolds or folds is a conventional technology in the relevant field, and will not be elaborated here.

[0050] In some embodiments, the rear floor structure 11 is a one-piece molded part, which can be formed by high-pressure die casting of aluminum alloy. The one-piece die casting part can effectively reduce the generation of defects such as porosity and shrinkage cavities by melting and casting in a high-pressure closed environment, and improve the density and strength of the rear floor structure 11. In this way, while ensuring that the various performance requirements of the rear floor structure 11 are met, the number of parts can be reduced and the assembly efficiency can be improved, thereby reducing the production cost of the whole vehicle, shortening the development cycle of the whole vehicle, and contributing to the lightweighting of the vehicle body.

[0051] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 and Figure 7As shown, at least one of the outer edge components 120 of the rear chassis component 12 is a replacement part 1201, which is a defective part or plastic part with the same structure as the original part 1202. The outer edge component 120 is a pre-installed rear chassis component 12 attached to the outside of the rear floor structure 11 in an easily removable position. For example, it includes at least one of the following: stabilizer bar assembly 1261, stabilizer bar connecting rod assembly 1262 (one on each side of the rear chassis assembly 1), and rear upper linkage assembly 1263 (one on each side of the rear chassis assembly 1). It has sufficient tooling or manual operation space relative to other rear chassis components 12, and can be easily replaced after reaching the destination. By replacing the outer edge component 120 with a defective or plastic part that has the same structure as the original part 1202 as a replacement part 1201 and assembling it according to the design torque, so that it is consistent with the actual vehicle state, the integrity of the rear chassis assembly 1 and the relative stability between the components during transportation can be guaranteed, while avoiding damage to the outer edge component 120 due to unforeseen bumps, wear and other situations during transportation.

[0052] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, the packaging structure 2 also includes a storage box 26, which is fixedly connected to the base plate 21 by bolts or welding. The storage box 26 contains the original 1202 of the outer edge component 120. When the rear chassis assembly 1 arrives at its destination, the pre-installed replacement 1201 of the rear chassis assembly 1 can be removed, the original 1202 of the outer edge component 120 stored in the storage box can be opened and taken out, and then assembled into the rear chassis assembly 1 according to the designed torque. At the same time, since the replacement 1201 of the outer edge component 120 has the same structure as the original 1202 of the outer edge component 120, the removed replacement 1201 can be put back into the storage box for reuse in the next shipment.

[0053] Specifically, such as Figure 7As shown, the storage box 26 includes an upper cover plate 261 and a lower storage box 262. The upper cover plate 261 and the lower storage box 262 are rotatably connected or detachably connected so that the upper cover plate 261 can be opened and closed relative to the lower storage box 262. The upper cover plate 261 and the lower storage box 262 respectively have a first storage cavity 2611 and a second storage cavity 2621 arranged opposite to each other. The first storage cavity 2611 is provided with a first fixing structure 2612, and the second storage cavity 2621 is provided with a second fixing structure 2622 corresponding to the first fixing structure 2612. The first fixing structure 2612 is adapted to the upper half of the outer edge component 120, and the second fixing structure 2622 is adapted to the lower half of the outer edge component 120. The first fixing structure 2612 and the second fixing structure 2622 are configured such that when the upper cover plate 261 is closed on the lower storage box 262, they can close accordingly and clamp the outer edge component 120 placed in the storage box 26. In this way, the original 1202 or replacement 1201 of the outer edge component 120 placed inside the storage box 26 can be securely and effectively fixed, preventing the outer edge component 120 from bumping and wearing off with the storage box 26 during transportation. Preferably, the first fixing structure 2612 and the second fixing structure 2622 can be molded from foam plastic, which has grooves corresponding to the shape of the outer edge component 120, which can provide shock absorption while ensuring effective fixation.

[0054] It is understandable that the relative opening and closing of the upper cover 261 and the lower storage box 262 can be achieved by a detachable connection method of screwing or snap-fitting, or by setting a hinge structure to allow the upper cover 261 to flip relative to the lower storage box 262. After closing, the upper cover 261 and the lower storage box 262 can be detachably fixed together by a structure such as buckles or bolts. The specific structure is conventional technology in the relevant field and will not be described in detail here.

[0055] like Figures 8 to 11As shown, in another embodiment, an integrated supply system for rear chassis components and rear floor is provided, including the integrated supply module 100 in the above embodiment. The integrated supply system is configured such that at least one integrated supply module 100 is placed on top of at least one other integrated supply module 100. The integrated supply module 100, or the uppermost integrated supply module 100, further includes a top plate 28, which is fixed to the upper end of the column 22. Thus, by setting the top plate 28, the upper ends of several columns 22 can be connected as a whole, improving the overall structural strength and stability of the packaging structure 2. Simultaneously, multiple integrated supply modules 100 can be stacked together vertically (z) and fixed by bolts for packaging and transportation. This results in a compact connection between adjacent integrated supply modules 100, facilitating assembly and disassembly, and balancing spatial layout, connection stability, and safety among components. It also allows for more efficient space utilization during transportation, effectively reducing transportation and storage costs.

[0056] It is understandable that, such as Figure 8 As shown, when the integrated supply module 100 is placed on top of other integrated supply modules 100, the base plate 21 of the upper integrated supply module 100 can be used as the top plate of the lower integrated supply module 100. The base plate 21 of the upper integrated supply module 100 can be fixedly connected to the column 22 of the lower integrated supply module 100 using bolts. Figure 9 As shown, when each integrated supply module 100 is provided with a top plate 28, the bottom plate 21 of the upper integrated supply module 100 and the top plate 28 of the lower integrated supply module 100 can also be fixedly connected together by bolts to ensure that the adjacent integrated supply modules 100 are compactly stacked and stably connected.

[0057] It is also understandable that, to accommodate and ensure the effective connection between the first limiting device 24 and the rear floor structure 11 and the columns 22, the four columns 22 of the integrated supply module 100 are designed with a wider spacing between the two columns 22 on the front side in the horizontal longitudinal direction x and a narrower spacing between the two columns 22 on the rear side in the horizontal longitudinal direction x. Therefore, when the integrated supply module 100 is placed on top of other integrated supply modules 100, two adjacent integrated supply modules 100 can be positioned as follows: Figure 8 The columns 22 of the two integrated supply modules 100 are arranged in the same orientation to ensure that the forces on the columns 22 in the vertical direction z are continuous; alternatively, they can be arranged as follows: Figure 9 The surfaces shown are arranged in opposite directions to facilitate the connection or removal of the bottom plate 21 of the upper integrated supply module 100 and the top plate 28 of the lower integrated supply module 100.

[0058] In some embodiments, such as Figure 1 , Figure 10 and Figure 11As shown, the packaging structure 2 also includes several supports 27, which are fixed to the lower end face of the base plate 21 around the base plate 21 in the circumference. The fixing methods include, but are not limited to, bolt connection or welding. By setting the supports 27, the base plate 21 can be raised, and a space for the forks of a forklift to pass through is formed between the supports 27 below the base plate 21, so as to facilitate the lifting of the forklift.

[0059] It is understandable that the shape, size, quantity and orientation of the support 27 can be reasonably selected and arranged according to the design size, shape and modulus of the base plate 21. It can be aligned with the column 22 in the vertical z direction to ensure the continuity of force in the vertical z direction; or it can be offset from the column 22 in the vertical z direction to facilitate connection or removal from the base plate 21.

[0060] It is also understandable that, such as Figure 10 and Figure 11 As shown, when the packaging structure 2 is equipped with a support 27 and each integrated supply module 100 is equipped with a top plate 28, the support 27 of the upper integrated supply module 100 and the top plate 28 of the lower integrated supply module 100 can be fixedly connected together by bolts, ensuring that the adjacent integrated supply modules 100 are compactly stacked and stably connected. At the same time, when the support 27 and the column 22 are misaligned in the vertical z direction, the two adjacent integrated supply modules 100 can be arranged in opposite directions to ensure that the support 27 of the upper integrated supply module 100 and the column 22 of the lower integrated supply module 100 are continuously stressed in the vertical z direction, or they can be arranged in the same direction to facilitate the connection or removal of the support 27 of the upper integrated supply module 100 and the top plate 28 of the lower integrated supply module 100.

[0061] Furthermore, in yet another embodiment, an integrated supply method for rear chassis components and a rear floor is provided, the integrated supply method comprising:

[0062] S100, the rear chassis components 12 and the rear floor structure 11 are assembled into the rear chassis assembly 1;

[0063] S200, the rear chassis assembly 1 is loaded and fixed by the packaging structure 2, wherein the fixing method is: fixing the longitudinal beam 111 of the rear floor structure 11 and the tire assembly 121 of the rear chassis components 12;

[0064] The S300 uses a transport equipment to transport the chassis assembly 1 via a packaging structure 2.

[0065] By integrating the dispersed rear chassis components 12 with the rear floor structure 11 and the packaging structure 2 into a compact, functional, and easy-to-assemble modular assembly, more efficient space utilization is allowed during modular transportation. This not only takes into account the spatial layout, connection stability, and safety of each component, but also effectively reduces transportation and warehousing costs. At the same time, the integrated rear chassis components 12 and rear floor structure 11 can be directly applied or simply assembled for final assembly after reaching the destination, thereby significantly shortening the production cycle and eliminating assembly errors, ensuring the overall performance of the vehicle.

[0066] Based on the above embodiments, in order to avoid damage to the rear chassis components 12 due to unforeseen bumps, wear and tear during transportation, step S100 further includes: attaching a defective part or plastic part with the same structure as the original part 1202 as a replacement part 1201 to the rear floor structure 11; wherein, the replacement part 1201 is at least one of the outer edge parts 120 of the rear chassis components 12;

[0067] Furthermore, after step S300, the process further includes: after the rear chassis assembly 1 is transported to its destination, the original part 1202 of the outer edge component 120 is used to replace the replacement part 1201. The original part 1202 of the outer edge component 120 can be placed in the storage box 26 and then transported together with the chassis assembly 1.

[0068] By replacing the outer edge component 120 with a defective or plastic part that has the same structure as the original part 1202 as a replacement part 1201, and assembling it according to the design torque, it can be made consistent with the actual vehicle state. This can maintain the original assembly requirements, ensure the integrity of the rear chassis assembly 1 and the relative stability between the components during transportation, and avoid bumping or wearing the outer edge component 120 during transportation. At the same time, since the replacement part 1201 is the outer edge component 120 of the rear chassis component 12, after reaching the destination, the original part 1202 and the replacement part 1201 can be replaced conveniently and quickly, thereby solving the problems of long production cycle and large assembly error caused by the existing decentralized supply and transportation method.
