[0002] With the rapid development of the new energy vehicle industry and the accelerated iteration of automotive products, consumer demands are becoming increasingly diversified. Existing new energy vehicles are no longer just tools for travel, but rather integrated spaces with a variety of intelligent components.

[0003] However, with the increasing number of intelligent components in vehicles, the vehicle body structure is becoming increasingly complex. In current automotive manufacturing processes, rear chassis components and the rear floor are typically designed, manufactured, and supplied separately. These scattered components require separate packaging and transportation, followed by multiple assembly steps upon arrival at the destination. This decentralized supply method not only increases production cycles but also raises logistics costs and inventory pressure; furthermore, it easily introduces assembly errors, affecting the overall performance of the vehicle. Therefore, a loading device is needed to achieve integrated transportation of rear chassis components and the rear floor. Utility Model Content

[0008] In one exemplary embodiment of this application, the second limiting device further includes at least two third limiting blocks, which are disposed opposite to and spaced apart on the base plate and are adapted to abut against the left and right sides of the tire assembly axial direction respectively, so as to limit the horizontal lateral movement of the rear chassis assembly.

[0009] In one exemplary embodiment of this application, the first limiting device further includes a support rod, which is arranged opposite to the clamping assembly in the vertical direction. When the clamping assembly is in the first state, the longitudinal beam is pressed between the clamping assembly and the support rod.

This not only takes into account the spatial layout, connection stability, and safety of each component, but also effectively reduces transportation and warehousing costs. Furthermore, the integrated rear chassis components and rear floor structure can be directly applied to final assembly operations upon arrival at the destination, thereby significantly shortening the production cycle, eliminating assembly errors, and ensuring the overall performance of the vehicle.

[0035] like Figures 1 to 3As shown, this embodiment provides a clamp for integrated transportation of rear chassis components and rear floor, including a base plate 21 and a plurality of columns 22. The plurality of columns 22 are fixed around the upper surface of the base plate 21 in the circumferential direction and form a loading space 23 suitable for placing the rear chassis assembly 1 above the base plate 21. The rear chassis assembly 1 includes a rear floor structure 11 and rear chassis components 12 attached to the rear floor structure 11. The rear chassis components 12 include at least a tire assembly 121. When the rear chassis assembly 1 is placed in the loading space 23, it is supported on the base plate 21 by the tire assembly 121. The columns 22 are provided with a first limiting device 24. The first limiting device 24 is configured to abut against or connect to the rear floor structure 11 when the rear chassis assembly 1 is placed in the loading space 23, so as to restrict the movement of the rear chassis assembly 1. The first limiting device 24 at least partially abuts against or connects 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 into a compact, functional, and easy-to-assemble modular assembly. The aforementioned clamp 2 can support and fix the rear chassis assembly 1 composed of the rear floor structure 11 and the rear chassis components 12, realizing integrated transportation of the rear floor structure 11 and the rear chassis components 12. At the same time, the cooperation between the clamp 2 and the rear chassis assembly 1 allows for more efficient use of space 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. Furthermore, the integrated rear chassis components 12 and the rear floor structure 11 can be directly applied to the final assembly operation after reaching the destination, thereby significantly shortening the production cycle, eliminating assembly errors, and ensuring the overall performance of the vehicle.

[0036] It is understood that the aforementioned rear chassis assembly 1 includes a rear floor structure 11 and rear chassis components 12 attached to the rear floor structure 11. The rear chassis components 12 include at least a tire assembly 121. In this embodiment, the rear chassis components 12 are assembled according to vehicle standards, specifically including a tire assembly 121, a powertrain 122, a suspension system 123, a transmission system 124, a braking system 125, a suspension system 126, and a wiring harness and sensor assembly 127. The rear floor structure 11 consists of two longitudinal beams 111 and... The closed frame structure formed by the two horizontal beams 112 can be manufactured as a single piece by die casting. 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 of these points can refer to the conventional attachment points of the rear chassis assembly 1. Attachment methods include, but are not limited to, bolt connections, welding, and snap-fit ​​connections to ensure a secure connection between each rear chassis component 12 and the rear floor structure 11. Specifically, the powertrain 122 is connected to the rear floor structure 11 via the suspension system 123, and the braking system 125 and tire assembly 121 are connected to the powertrain 122 and the rear floor structure 11 via the suspension system 126 and transmission system 124. Simultaneously, each rear chassis component 12 is interconnected via wiring harnesses and sensor assemblies 127 to complete the assembly of the rear chassis assembly 1.

[0037] For example, such as Figure 1 and Figure 2As shown, in this embodiment, the clamp 2 includes a base plate 21 and four columns 22 arranged circumferentially around the base plate 21. Each column 22 is provided with a first limiting device 24. The first limiting device 24 can be a connecting device that is rigidly connected by means of plugging, snapping, or bolting, or a connecting device that is softly connected by means of ropes, straps, etc., or a clamping device such as the clamp 2 or a gripper that has a clamping function and can perform a clamping action on the end of the longitudinal beam 111 of the rear floor structure 11 and clamp it. The goal is simply to restrict the movement and rotation of the rear floor structure 11. The assembled rear chassis assembly 1 is then placed in the loading space 23 using a forklift or crane. At this point, 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 four columns 22. The first limiting device 24 abuts against or connects to these four ends, thus restricting the movement of the rear chassis assembly 1 and fixing it within the loading space 23. Preferably, since the longitudinal beams 111 of the rear floor structure 11 are wider at the front and narrower at the rear in the horizontal transverse direction (y), the four columns 22 can be designed such that the distance between the two columns 22 at the front in the horizontal longitudinal direction (x) is wider, and the distance between the two columns 22 at the rear in the horizontal longitudinal direction (x) is narrower, to accommodate and ensure effective connection between the first limiting device 24 and the rear floor structure 11.

[0038] In some embodiments, such as Figure 1 and Figure 2 As shown, the clamp 2 also includes a second limiting device 25, which is located on the base plate 21. It can be a limiting structure that abuts against the four sides of the tire assembly 121 in the horizontal direction, or a connecting device that wraps and binds the tire assembly 121 by means of ropes, straps, etc., or a clamping device such as the clamp 2 or the gripper that has a clamping function and can perform a clamping action on the tire assembly 121 of the rear chassis component 12 and clamp it. In this way, when the rear chassis assembly 1 is placed in the loading space 23, the second limiting device 25 abuts against or is connected to the tire assembly 121, which can work with the first limiting device 24 to further restrict the movement and rotation of the rear chassis assembly 1, ensuring that the rear chassis assembly 1 is reliably fixed in the loading space 23.

[0039] 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.

[0040] In some embodiments, such as Figure 1 and Figure 2As 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 can press 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 chassis assembly. The rear chassis assembly 1 is positioned relative to the loading space 23 for entry and exit; 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 relative to each other and at intervals. The fixing 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 horizontal longitudinal movement of the rear chassis assembly 1. 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.

[0041] 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.

[0042] In some embodiments, such as Figure 1 and Figure 2As shown, the second limiting device 25 also includes at least two third limiting blocks 253, which are fixedly connected to the base plate 21 relative to each other and at intervals. The fixing 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 understandable that there are two tire assemblies 121 in the rear chassis assembly 1. Therefore, the two third limiting blocks 253 can be respectively set on the left and right sides of one of the tire assemblies 121, or one of the third limiting blocks 253 can be set on the left side of one of the tire assemblies 121 and the other third limiting block 253 can be set on the right side of the other tire assembly 121. In this case, the two third limiting blocks 253 are located on the relatively inner or relatively outer sides of the two tire assemblies 121 in the horizontal lateral y, which can restrict the movement of the rear chassis assembly 1 in the horizontal lateral y.

[0043] Furthermore, such as Figure 1 and Figure 2 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.

[0044] 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 2 and Figure 4As 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 clamp 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.

[0045] Specifically, the first limiting block 251 can be slidably connected to the base plate 21 to achieve state switching between the third and fourth states. For example... Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the base plate 21 has a groove 211 extending horizontally in the lateral direction y. The groove 211 has a first end 2111 and a second end 2112 distributed horizontally in the lateral direction y. A first limiting block 251 slides 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 a 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 end 2112. The limiting 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 the 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 bolt 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 first limiting block 251 is fixed on the base plate 21 by tightening the bolt, which can lock the first limiting block 251 in the corresponding state and ensure the reliability of the limiting during transportation.

[0046] In some embodiments, such as Figure 4As shown, the first end 2111 of the groove 211 extends along any side (such as the front or rear side) of the horizontal longitudinal direction x to form a third end 2113. At this time, the groove 211 is F-shaped, and the first limiting block 251 can slide along the groove 211 between the first end 2111 and the third end 2113. With the above setting, when the first limiting block 251 is in the third state, the distance between the first limiting block 251 and the second limiting block 252 can be adjusted to accommodate tires of different sizes.

[0047] It is understood that 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. For example, a receiving groove is provided in the base plate 21, and the first limiting block 251 is provided 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.

[0048] In some embodiments, such as Figure 1 and Figure 2 As shown, the clamp 2 also includes several supports 26, which are fixed to the lower end face of the base plate 21 around its circumference. The supports 26 allow the base plate 21 to be raised, creating space between them for the forks of a forklift to pass through, facilitating lifting. It is understood that the shape, size, number, and orientation of the supports 26 can be rationally selected and arranged according to the design dimensions, shape, and modulus of the base plate 21. They can correspond to the column 22 in the vertical direction z to ensure continuous force distribution in the vertical direction z; or they can be offset from the column 22 in the vertical direction z to facilitate connection or removal from the base plate 21.

[0049] like Figures 5 to 8As shown, in another embodiment, a transportation system for integrated transportation of rear chassis components and the rear floor is provided, including the clamps 2 described in the above embodiment. The transportation system is configured such that at least one clamp 2 is placed on top of at least one other clamp 2. The clamp 2, or the clamp placed on the uppermost layer, further includes a top plate 27, which is fixed to the upper end of the uprights 22. Thus, by setting the top plate 27, the upper ends of several uprights 22 can be connected as a whole, improving the overall structural strength and stability of the clamp 2. Simultaneously, multiple clamps 2 can be stacked together vertically and fixed to each other by bolts. This results in a compact connection between adjacent clamps 2, facilitating assembly and disassembly, and balancing spatial layout, connection stability, and safety among components. It allows for more efficient space utilization during transportation, effectively reducing transportation and storage costs.

[0050] It is understandable that, such as Figure 5 As shown, when clamp 2 is placed on top of other clamps 2, the base plate 21 of the upper clamp 2 can be used as the top plate of the lower clamp 2. The base plate 21 of the upper clamp 2 and the column 22 of the lower clamp 2 can be fixedly connected together by bolts. Figure 6 As shown, when each clamp 2 is provided with a top plate 27, the bottom plate 21 of the upper clamp 2 and the top plate 27 of the lower clamp 2 can also be fixedly connected together by bolts to ensure that the upper and lower adjacent clamps 2 are compactly stacked and stably connected.

[0051] 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 clamp 2 are designed with a wider spacing between the two columns 22 on the front side of the horizontal longitudinal direction x and a narrower spacing between the two columns 22 on the rear side of the horizontal longitudinal direction x. Therefore, when the clamp 2 is placed on top of other clamps 2, two adjacent clamps 2 can be positioned as follows: Figure 5 The two clamps 2 are arranged with the same orientation to ensure that the columns 22 of the upper and lower clamps 2 experience continuous force in the vertical direction z; alternatively, they can be arranged as follows: Figure 6 The surfaces are arranged in opposite directions to facilitate the connection or removal of the bottom plate 21 of the upper clamp 2 and the top plate 27 or column 22 of the lower clamp 2.

[0052] In addition, such as Figure 7 and Figure 8As shown, when each clamp 2 is equipped with a support 26 and a top plate 27, the support 26 of the upper clamp 2 and the top plate 27 of the lower clamp 2 can be fixedly connected together by bolts, ensuring that the upper and lower adjacent clamps 2 are compactly stacked and stably connected. Simultaneously, when the support 26 and the column 22 correspond in the vertical z direction, the two adjacent clamps 2 can be arranged in the same orientation to ensure continuous force on the columns 22 in the vertical z direction. When the support 26 and the column 22 are misaligned in the vertical z direction, the two adjacent clamps 2 can be arranged in opposite orientations to ensure continuous force on the upper clamp 26 and the lower clamp 2's column 22 in the vertical z direction, or they can be arranged in opposite orientations to facilitate connection or removal of the upper clamp 2's support 26 and the lower clamp 2's top plate 27.

[0053] In some embodiments, such as Figure 1 and Figure 2 As shown, the clamp 2 also includes a storage box 28, which can be fixedly connected to the base plate 21 by bolts or welding. The storage box 28 can hold fasteners such as connecting bolts and operating tools such as wrenches for disassembling or connecting two adjacent clamps 2, and can also loosen / tighten the bolts of the locking mechanism 2511.
