Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle components, in particular to a spliced carriage. BACKGROUND

[0002] In the field of automobile transportation, the manufacturing and assembly technology of carriages has been continuously developing. Traditional carriage manufacturing often adopts a monolithic structure, where parts are processed through complex procedures in the factory and then transported as a whole to the place of use. However, this approach has many shortcomings.

[0003] On the one hand, the traditional carriage assembly is inefficient. It often requires a large number of complex procedures such as welding and spraying, which not only takes a long time and requires high skills of workers, but also makes it difficult to quickly respond to market demand. For example, in the case of emergency orders or off-site assembly, the traditional carriage assembly method is not up to the task.

[0004] On the other hand, the traditional carriage transportation cost is high. Due to its large overall size, it occupies a lot of space during transportation, resulting in high transportation costs, especially when transporting over long distances, which is not cost-effective.

[0005] In addition, the traditional carriage lacks flexibility and is difficult to quickly adjust or assemble according to different transportation needs, making it difficult to meet the increasingly diverse and personalized transportation scenario requirements. At the same time, the welding and spraying processes also produce harmful gases and dust, polluting the environment and not meeting the current trend of green manufacturing.

[0006] In summary, the traditional carriage manufacturing and transportation method has obvious problems in efficiency, cost, flexibility, and environmental protection, and an innovative carriage design is needed to solve these problems. CONTENT OF THE INVENTION

[0007] The technical problem to be solved by the present application is to provide a spliced carriage that is designed in a spliced structure to achieve quick assembly, facilitate batch off-site assembly, has a small shipping volume, low transportation cost, and does not require welding and spraying at the customer end.

[0008] The technical scheme adopted by the present application is: a spliced carriage, comprising a top plate assembly, a left side plate assembly, a right side plate assembly and a chassis assembly, the top plate assembly comprises upper frames arranged on the left and right sides of the lower bottom surface, the upper frames are rectangular tubular structures, the top of the left side plate assembly and the right side plate assembly is provided with a bending piece, the upper frame is arranged on the bending piece and is locked by bolts, the longitudinal section of the bending piece is in a stepped shape, the upper part of the bending piece is attached to the inner side of the upper frame, and the lower part of the bending piece is attached to the outer side of the left side plate assembly or the right side plate assembly, grooves are formed on the left and right sides of the top surface of the chassis assembly, and a boundary beam is mounted at the grooves, the left side plate assembly and the right side plate assembly are locked with the chassis assembly through the boundary beam, the boundary beam is attached to the inner side and the bottom surface of the left side plate assembly or the right side plate assembly, and the boundary beam is attached to the outer side of the chassis assembly and extends downward to form a connecting part connected with the vehicle body.

[0009] Compared with the prior art, the present application has the following advantages: first, the spliced structure is adopted, the upper frame of the top plate assembly can be directly arranged on the bending piece of the left side plate assembly and the right side plate assembly and locked by bolts, and the side plate assembly is locked with the chassis assembly through the boundary beam, without the need for complex welding and spraying processes, which greatly shortens the assembly time, reduces the requirement for worker skills, can quickly respond to market demand, and is especially suitable for emergency orders or off-site assembly. The various components of the carriage can be pre-produced in the factory, and then transported to the assembly site in the form of CKD (completely disassembled), and only the splicing and assembly according to the design requirements are needed on site, which is beneficial to realize batch production and off-site assembly, improves the production efficiency and flexibility, and can better meet the individual needs of different regions and customers. Since the components of the carriage can be disassembled into relatively small parts for transportation, compared with the traditional integral carriage, the volume occupied by the carriage during transportation is greatly reduced, which is convenient for packaging and transportation, thereby significantly reducing the transportation cost of the product and improving the economic efficiency and market competitiveness of the product. In addition, no harmful gas and dust generating processes such as welding and spraying are required during assembly, which reduces environmental pollution and meets the current trend of green manufacturing and sustainable development, which is beneficial to environmental protection and improvement of the environmental friendliness of the production process.

[0010] Secondly, the longitudinal section of the bending piece is in a stepped shape, the upper part of the bending piece is attached to the inner side of the upper frame, and the lower part of the bending piece is attached to the outer side of the side plate assembly, which makes the connection between the top plate assembly and the side plate assembly more compact and firm. The boundary beam is attached to the inner side and the bottom surface of the side plate assembly, and is attached to the outer side of the chassis assembly, which further enhances the connection strength between the side plate assembly and the chassis assembly, ensures the stability and safety of the carriage during transportation, and can effectively bear the weight of goods and various stresses during transportation.

[0011] In some embodiments of the present application, the top plate assembly comprises a plurality of top plates and a plurality of upper crossbeams, the plurality of top plates are sequentially connected front to back, and the two ends of the upper crossbeams are connected with the upper frame, and the edges of the adjacent two top plates are all erected on the upper crossbeams.

[0012] In the present application, the left and right upper frames and the upper crossbeams build a frame structure, which cooperates to realize the installation of the top plate. The above structure design can improve the load-bearing capacity and stability of the top plate. Through the connection of the plurality of top plates and the support of the upper crossbeams, the stress can be more evenly distributed when the top plate bears the weight of the goods, reducing the deformation or damage caused by excessive local stress, and also helping to improve the overall structural strength of the carriage.

[0013] In some embodiments of the present application, the top plate surface is regularly provided with a convex rib, the convex rib is in a strip-shaped structure, and the length direction of the convex rib is perpendicular to the upper frame.

[0014] The design of the convex rib can increase the bending strength and rigidity of the top plate, making it more resistant when bearing the force perpendicular to the surface of the top plate. This structure can effectively prevent the top plate from being depressed or bent and deformed due to the extrusion or impact of the goods during transportation, prolonging the service life of the top plate.

[0015] In some embodiments of the present application, the right side plate assembly comprises a plurality of right side plates and two reinforcing plates, the plurality of right side plates are sequentially connected front to back, and the two reinforcing plates are installed one above the other on the inner wall surface formed by the plurality of right side plates, the reinforcing plates connect all the right side plates, and the reinforcing plates are in a U-shaped reinforcing plate structure; the cross section of the right side plate is in a rectangular wave structure.

[0016] The setting of the U-shaped reinforcing plate can significantly enhance the overall strength and rigidity of the right side plate, so that it can better bear the lateral pressure from the goods. At the same time, the rectangular wave structure of the cross section of the right side plate can also increase its bending resistance, so that the right side plate is not easy to deform during transportation, improving the reliability and durability of the carriage.

[0017] In some embodiments of the present application, the left side plate assembly comprises at least two left side plates and a side door assembly, the left side plates are connected front to back to the side door assembly, and the inner wall surface of the left side plate is connected with two reinforcing plates; the cross section of the left side plate is in a rectangular wave structure.

[0018] This design of the left side plate assembly can also improve the structural strength of the left side plate. The connection of the side door assembly and the left side plate and the installation of the reinforcing plate make the left side plate more stable when the side door is opened and closed, and are not easy to shake or deform. The left side plate with a rectangular wave structure can also enhance its bending resistance, ensuring the stability and safety of the left side plate during transportation.

[0019] In some embodiments of the present application, the bottom of the left side plate assembly and the right side plate assembly is provided with a lower frame, which is a rectangular tubular structure, and the lower frame is installed on the side beam.

[0020] The provision of the lower frame can provide additional support and fixation for the left side plate assembly and the right side plate assembly, making the connection with the side beam more secure. The rectangular tubular structure of the lower frame has high strength and rigidity, which can effectively withstand the force from below and prevent the side plate assembly from deforming or being damaged due to the force on the bottom during transportation.

[0021] In some embodiments of the present application, the chassis assembly includes a bottom deck, a plurality of lower cross beams arranged regularly on the same horizontal plane, and at least two lower longitudinal beams connected below the lower cross beams, and the bottom deck is laid above the plane formed by the plurality of lower cross beams.

[0022] This design of the chassis assembly can provide good load-bearing capacity and structural stability. The combination of the plurality of lower cross beams and the lower longitudinal beams forms a solid frame structure that can evenly distribute the weight of the goods and reduce the situation of excessive local stress.

[0023] In some embodiments of the present application, the lower longitudinal beams are in the shape of a rectangular tube, the opposite faces of the two lower longitudinal beams are open, and a plurality of connecting pieces are arranged on the opposite faces of the two lower longitudinal beams, and the connecting pieces are in the shape of a polygon with right-angle bends. The trapezoidal structure of the connecting pieces can enhance the connection strength between the lower longitudinal beams, making the chassis assembly more secure and able to withstand larger loads.

[0024] In some embodiments of the present application, the side beam wraps around the end face of the lower cross beam, the top face of the side beam is lined below the bottom deck, and the lower part of the side beam extends out of the lower cross beam and bends to the side of the lower longitudinal beam in the shape of L.

[0025] This design of the side beam can better protect the end of the lower cross beam and prevent it from being collided or worn during transportation. At the same time, the L-shaped bent part of the side beam can better cooperate with the lower longitudinal beam, increase the connection area between the side beam and the lower longitudinal beam, improve the firmness and stability of the connection, further enhance the overall strength of the chassis assembly, and ensure the stability and safety of the carriage during driving.

[0026] In some embodiments of the present application, the present application also includes a front side plate assembly and a rear door assembly, the rear end of the roof assembly is provided with a rear door rain eave, and the left side of the roof assembly is provided with a left side rain eave located directly above the side door assembly.

[0027] The provision of the rain eave can prevent rainwater or other liquids from directly entering the interior of the carriage to a certain extent, and at the same time, it will not affect the normal opening and closing and use of the door, improving the practicality and reliability of the carriage.
