[0022] Please see Figure 1 , Figure 1 A riveted cargo box provided in one embodiment of the present utility model includes: Base plate assembly 10, such as Figure 2 As shown, the system includes a base frame with a bottom edge beam 102, a front crossbeam 101, and a rear crossbeam 103. The base frame is covered with flooring, which can be made of bamboo, steel patterned flooring, corrugated flooring, etc. The bottom edge beam 102, the front crossbeam 101, and the rear crossbeam 103 are all formed by bending metal plates. The bottom edge beam 102, the front crossbeam 101, and the rear crossbeam 103 are all provided with a stepped structure with a step height of 20mm. The front bulkhead assembly 20 includes a front bulkhead panel 201. Front pillars 202 are welded to the left and right ends of the front bulkhead panel 201. The top and bottom of the front bulkhead panel 201 are respectively welded to the upper front bulkhead beam 203 and the lower front bulkhead beam 204. The lower front bulkhead beam 204 can be bolted to the front crossbeam 101 in the X direction. The rear assembly 30 includes a rear door frame, which includes left and right rear pillars 301, an upper rear beam 302, and a lower rear beam 303. Rear door panels 304 are hinged to the left and right rear pillars 301, and the lower rear beam 303 can be riveted to the step of the rear crossbeam 103 in the Z direction. The side panel assembly 40 includes a side panel 401. A front mounting plate 404 and a rear mounting plate 405 are welded to the front and rear ends of the side panel 401. The front mounting plate 404 can be riveted to the front upright 202 in the Y direction from inside the cargo compartment to the outside. The rear mounting plate 405 can be riveted to the rear upright 301 in the X direction from inside the cargo compartment to the outside. The top and bottom of the side panel 401 are provided with an upper side beam 402 and a lower side beam 403. The lower side beam 403 can be riveted to the step of the bottom side beam 102 in the Z direction from inside the cargo compartment to the outside. The top cover assembly 50 includes a top cover plate 501. The bottom perimeter of the top cover plate 501 is welded with a front side beam 502, a left side beam 503, a right side beam 504, and a rear side beam 505. Figure 6 As shown, the front side beam 502 of the roof can be riveted to the upper side beam 203 of the front bulkhead in the X direction from the inside to the outside of the cargo compartment, as shown. Figure 8 As shown, the left side beam 503 and the right side beam 504 of the top cover can be riveted to the upper side beam 402 of the side wall from the inside to the outside in the Y direction, as shown. Figure 7 As shown, the rear side beam 505 of the top cover can be riveted to the upper side beam 302 of the rear enclosure from the inside to the outside in the X direction.

[0023] The cargo box of this utility model is formed by riveting together six plate assemblies. Before being assembled into a box body, the six assemblies can be stacked as sets, occupying far less space than existing welded boxes. The riveting assembly is no longer limited by the professionalism of the operator and the work site, and can be assembled in different locations, which helps to save transportation costs. For example, after welding a 4m box body, a single flatbed truck can only carry a maximum of 4 boxes for transport, while using the assembly pieces of this utility model, a single flatbed truck can carry 23 sets at a time, greatly saving transportation costs. Furthermore, through the design of the connection positions, the entire box body of this utility model does not require operation at the bottom or top of the box body, thereby reducing the height of the rail trolley, reducing the frequency of trolley use, and improving production efficiency.

[0024] For example, in this embodiment, such as Figure 2 As shown, front positioning posts 104 are provided at both front corners of the base plate frame, and the front positioning posts 104 are welded between the bottom edge beam 102 and the front crossbeam 101. Figure 4 As shown, the front pillar 202 is a bent metal plate part. The front pillar 202 is inserted into the front positioning pillar 104. The front positioning pillar 202 is positioned by the front positioning pillar 104, thereby realizing convenient positioning of the front assembly 20.

[0025] For example, in this embodiment, rear positioning posts 105 are provided at both rear corners of the base plate frame, and the rear positioning posts 105 are welded between the bottom edge beam 102 and the rear cross beam 103. Figure 5 As shown, the rear pillar 301 is a bent metal plate part. The rear pillar 301 is inserted into the rear positioning pillar 105. The rear positioning pillar 301 is positioned by the rear positioning pillar 105, thereby realizing convenient positioning of the rear assembly 30.

[0026] For example, in this embodiment, such as Figure 3 As shown, the base plate frame has several intersecting crossbeams 107 and longitudinal beams 106 in the middle. Several slots 108 are provided in the middle of the longitudinal beams 106, and the crossbeams 107 are inserted into the slots 108. The longitudinal beams 106 and crossbeams 107 form a flat grid-like plug-in low-floor structure. Reinforcing plates 109 are welded to the longitudinal beams 106, located outside the slots 108, to provide lateral support for the crossbeams 107. C-shaped fasteners 111 are fastened into the slots 108 to provide bottom support for the crossbeams 107. In this base plate frame, the crossbeams 107 and longitudinal beams 106 are connected as a whole, resulting in better base plate frame strength, lower height, and greater advantages for stacking and transportation.

[0027] It is worth noting that the cross-section of the beam 107 is C-shaped, and the C-shaped side of the beam 107 has an inwardly facing flange. A support plate 110 with a C-shaped cross-section is welded to the inner side of the beam 107 at the slot 108. The cross-section of the beam 107 with the flange is higher in bending stiffness and structural strength, and the support plate 110 improves the structural strength of the connection between the beam 107 and the longitudinal beam 106, resulting in higher structural strength of the base plate frame.

[0028] For example, in this embodiment, reference is made to Figure 1 The top cover plate 501 is a longitudinally corrugated plate with corrugated strips parallel to the vehicle's forward direction. This type of top cover plate 501 has lower wind resistance, and compared to the existing top cover structure with transverse corrugated arrangement, the top cover plate 501 in this embodiment has fewer corrugated heads, fewer stamping times per vehicle, shorter weld length during production, and higher welding efficiency.

[0029] For example, in this embodiment, reference is made to Figure 6 , Figure 8 The front beam 502, left beam 503, and right beam 504 of the roof are all bent metal plates and have arc-shaped airflow guide surfaces. The arc-shaped airflow guide surfaces are located at the edge of the roof, which reduces wind resistance during vehicle movement.

[0030] For example, in this embodiment, such as Figure 7 As shown, a water baffle 506 is welded to the rear end of the top cover plate 501. The water baffle 506 has an upwardly bent edge. The water baffle 506 can prevent water accumulated on the top cover plate 501 from dripping from the rear end of the cargo compartment and affecting cargo loading and unloading.

[0031] For example, in this embodiment, the front upper side beam 203, the front mounting plate 404, and the side upper side beam 402 are all Z-shaped metal plates, each including a central positioning portion 4041 and mounting portions 4042 located on both sides of the positioning portion 4041. (See reference) Figure 4 The mounting portion 4042 on one side of the front mounting plate 404 is attached to and welded to the side end of the side panel 401. The positioning portion 4041 of the front mounting plate 404 abuts against the front pillar 202, and the mounting portion 4042 on the other side of the front mounting plate 404 is riveted to the front pillar 202.

[0032] For example, in this embodiment, reference is made to Figure 6 The mounting part 4042 and positioning part 4041 on one side of the upper beam 203 of the front bulkhead abuts against and is welded to the top of the front bulkhead 201, and the mounting part 4042 on the other side of the upper beam 203 of the front bulkhead is riveted to the front beam 502 of the roof.

[0033] For example, in this embodiment, reference is made to Figure 8The mounting part 4042 and positioning part 4041 on one side of the upper side beam 402 abut against and are welded to the top of the side panel 401, and the mounting part 4042 on the other side of the upper side beam 402 is riveted to the left side beam 503 and the right side beam 504 of the top cover.

[0034] For example, in this embodiment, reference is made to Figure 5 As shown, the rear mounting plate 405 is an L-shaped plate. One side of the rear mounting plate 405 is welded to the rear panel, and the other side of the rear mounting plate 405 is riveted to the rear pillar 301.

[0035] For example, in this embodiment, reference is made to Figure 9 , Figure 10 , Figure 11 The lower front beam 204, the lower side beam 403, and the lower rear beam 303 are all C-shaped plates covering the outside of the steps of the bottom beam 102, the front crossbeam 101, and the rear crossbeam 103. It is worth noting that a water guide groove 601 is formed around the bottom plate assembly 10 between the steps and the side walls to prevent water from accumulating and wetting the goods.

[0036] In this invention, the front upper side beam 203, front mounting plate 404, side upper side beam 402, rear mounting plate 405, front lower side beam 204, side lower side beam 403, and rear lower side beam 303 are all made of bent plates. This avoids the problems of poor surface uniformity and uneven surface differences that exist in existing rectangular tube side beam combinations used in cargo box assembly. In existing rectangular tube frames, the rectangular tubes are flush with the front and rear uprights 301 and the lower side beams, resulting in poor surface uniformity and low efficiency in adhesive repair. Furthermore, adhesive is required at the joint between the lower side beam rectangular tube and the bottom plate side beam. With the C-shaped bent plates, the lower side beam covers the bottom plate side beam, eliminating this adhesive joint. After replacing the rectangular tubes with these C-shaped bent plates, the bottom plate side beam, as an internal component of the cargo box, does not require separate painting, reducing one process step.

[0037] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
