Description

Technical Field

[0001] This utility model relates to the field of truck body technology, specifically a flat corrugated composite cargo box. Background Technology

[0002] As a core component of freight vehicles, the cargo box's structure and function directly impact transportation efficiency, cargo safety, and applicable scenarios. Currently, most common cargo box side panels on the market utilize corrugated sheet structures, as shown in the attached diagram in the instruction manual. Figure 6 The image shows a structural diagram of a corrugated board cargo box in the prior art, comprising a floor plate, fixed columns, a top plate, and multiple corrugated boards. The wavy folds of the corrugated boards form continuous "arched support units," effectively dispersing external impact forces and avoiding stress concentration, thereby improving the cargo box's collision resistance and structural strength. However, existing corrugated board cargo boxes still have the following drawbacks in practical use:

[0003] 1. Advertising stickers are usually pasted on both sides of the truck body. The grooved structure of the corrugated board means that the stickers must be cut to fit the side wall completely, which makes the pasting operation cumbersome and time-consuming. In addition, the edges of the cut stickers are prone to curling up, which reduces the overall aesthetics.

[0004] 2. The existing freight cars are not equipped with dedicated ladders or boarding assistance devices, and there is a large height difference between the car body and the ground, which makes it extremely inconvenient for loading and unloading personnel or maintenance personnel to enter the car body, posing a safety hazard.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example: This utility model provides a technical solution for a flat corrugated composite cargo box, such as... Figures 1-5 As shown, the cargo box body 100 includes a floor plate 1 for fixed installation on the truck frame. Vertical fixing posts 11 are fixedly installed at the four corners of the top of the floor plate 1. A top plate 12 is fixedly installed on the top of the four fixing posts 11. A corrugated plate 13 is fixedly installed between the two fixing posts 11 located on the front side of the top of the floor plate 1. A corrugated plate 14 is fixedly installed between the two fixing posts 11 located on the left side of the top of the floor plate 1. Two upright posts 19 are fixedly installed between the two fixing posts 11 located on the right side of the top of the floor plate 1. A corrugated plate 15 is fixedly installed between the two fixing posts 11 and the two upright posts 19 on the right side of the top of the floor plate 1. The cargo box body 100 has a notch 16 on the right side and a notch 27 on the rear side. Specifically, the notch 16 is composed of the floor plate 1, the top plate 12 and the two upright posts 19, and the notch 27 is composed of the floor plate 1, the top plate 12 and the two fixing posts 11 located on the rear side of the floor plate 1.

[0031] A flat plate 2 is fixedly installed on the side of the corrugated plate 13 and the two corrugated plates 3 15 that are far apart from each other. The corrugated plate 13, corrugated plate 2 14, corrugated plate 3 15 and flat plate 2 are all made of stainless steel plates, and the bottom plate 1, the fixing column 11, the top plate 12, the corrugated plate 13, corrugated plate 2 14, corrugated plate 3 15 and flat plate 2 are all fixed by welding.

[0032] A ladder assembly 3 is installed on the base plate 1 and below the second notch 17. An adjustment mechanism 4 that acts on the ladder assembly 3 is installed on the base plate 1. The adjustment mechanism 4 allows the ladder assembly 3 to have two forms:

[0033] First configuration: The ladder component 3 is located outside the second notch 17, and the lowest end of the ladder component 3 is located above the bottom of the base plate 1;

[0034] Second form: The highest end of the ladder component 3 is located below the top of the base plate 1, and there is a gap between the lowest end and the highest end.

[0035] The design of the flat panel 2 makes both sides of the cargo box body 100 flat, which facilitates the pasting of advertising stickers, improves the aesthetics of the pasted stickers, and is beneficial for advertising display. The design of the ladder assembly 3 and the adjustment mechanism 4 allows the cargo box body 100 to be installed on the truck frame. During subsequent use, when the ladder assembly 3 needs to be used, the adjustment mechanism 4 adjusts the ladder assembly 3 to a second configuration. The highest point of the ladder assembly 3 is located below the top of the bottom panel 1, and there is a gap between the lowest point and the highest point, reducing the height of the lowest point of the ladder assembly 3. This allows personnel to easily access the cargo box body 100 by climbing the ladder assembly 3 to the top of the floor plate 1, thus reducing safety hazards. When the ladder is not needed, the ladder assembly 3 can be adjusted by the adjustment mechanism 4 to form a first form, with the ladder assembly 3 located outside the notch 17 and the lowest point of the ladder assembly 3 above the bottom of the floor plate 1. This allows the ladder assembly 3 to be stored at the rear of the cargo box body 100 and above the floor plate 1, effectively preventing the lowest point of the ladder assembly 3 from being too low when it is in the first form, which could affect the normal driving of the vehicle.

[0036] As one embodiment: the ladder assembly 3 includes two sets of hinged rods, with a lower step 31, a middle step 32, and an upper step 33 hinged sequentially from bottom to top between the two sets of hinged rods; each hinged rod set includes a first short rod 34, a long rod 35, and a second short rod 36, all arranged in parallel; the middle of the side wall of the lower step 31 is hinged to the bottom end of the first short rod 34, and a long rod 35 is hinged to one end of the side wall; the middle of the long rod 35 is hinged to one end of the middle step 32, and its top end is hinged to the end of the upper step 33; the other end of the first short rod 34 is hinged to one end of the side wall of the middle step 32, and the other end of the side wall of the middle step 32 is hinged to the second short rod 36; the other end of the second short rod 36... The upper step 33 is hinged to the middle of the side wall of the upper step 33. The upper step 33 is hinged to the base plate 1 via a hinge shaft 331. The adjustment mechanism 4 is used to rotate or stop the hinge shaft 331 on the base plate 1. In use, after the cargo box body 100 is installed on the truck frame, when the ladder assembly 3 is needed during subsequent use, the adjustment mechanism 4 is used to rotate the hinge shaft 331 on the base plate 1, so that the upper step 33 rotates to a horizontal position. At this time, the first short rod 34, the long rod 35, and the second short rod 36 rotate vertically on the side walls of the upper step 33, the middle step 32, and the lower step 31, respectively. The upper step 33, the middle step 32, and the lower step 31 are all horizontal. At this time, the ladder assembly 3 is in the second state, specifically as follows: Figure 2 As shown, personnel can step on the lower pedal 31, middle pedal 32, and upper pedal 33 in sequence to enter the cargo compartment 100. When the ladder assembly 3 is not needed, the hinge shaft 331 is rotated on the base plate 1 by the adjustment mechanism 4, so that the upper pedal 33 rotates to a vertical position. At this time, the first short rod 34, the long rod 35, and the second short rod 36 rotate at an angle on the side walls of the upper pedal 33, the middle pedal 32, and the lower pedal 31, respectively. The upper pedal 33, the middle pedal 32, and the lower pedal 31 are all vertical and fit together in sequence. At this time, the ladder assembly 3 is in the first state, specifically as shown in the figure. Figure 4 As shown, this achieves the storage effect for ladder component 3.

[0037] As one embodiment: The rear sidewall of the base plate 1 is symmetrically fixed with hinge blocks 18. The upper pedal 33 is hinged between the two hinge blocks 18 via a hinge shaft 331. The adjustment mechanism 4 includes a worm gear 41 coaxially fixed to the hinge shaft 331. A worm 42 meshing with the worm gear 41 is rotatably mounted on one of the hinge blocks 18. A handwheel 43 is synchronously fixed to the end of the worm 42. In use, the user rotates the worm 42 on the hinge block 18 via the handwheel 43, thereby driving the hinge shaft 331 to rotate on the two hinge blocks 18 via the worm gear 41. The operation is simple. Since the worm gear 41 and the worm 42 have a self-locking property, the worm gear 41 will not rotate when the worm 42 is not rotated, thus fixing the position of the hinge shaft 331 for easy use. The design of the handwheel 43 facilitates the rotation of the worm 42.

[0038] As one embodiment: both hinge blocks 18 are located on one side of the rear side of the base plate 1. By having both hinge blocks 18 located on one side of the rear side of the base plate 1, the ladder assembly 3 is located on one side of the rear side of the cargo box body 100, which makes way for the middle position of the rear side of the cargo box body 100, thereby facilitating personnel to load and unload goods inside the cargo box body 100.

[0039] As one embodiment: the planar plate 2 is fixed to the base plate 1, the fixed column 11 and the top plate 12 by laser welding. When the planar plate 2 is welded, full welding is performed by laser welding to improve the welding strength. It is worth noting that the two planar plates 2 located on the top right side of the base plate 1 are also fixed to the two columns 19 by laser welding.

[0040] As one embodiment: between the two fixed posts 11 located on the top left of the base plate 1, a plurality of reinforcing plates 14 are welded together, each of which is fixed to a corrugated plate 2 14. The two fixed posts 11 located on the top right of the base plate 1 are each provided with a reinforcing plate assembly. The reinforcing plate assembly includes a plurality of reinforcing plates 2 6 arranged in a vertical linear array and welded to the fixed posts 11. The plurality of reinforcing plates 2 6 of the two sets of reinforcing plate assemblies are welded and fixed to two corrugated plates 3 15 respectively. The other end of the plurality of reinforcing plates 2 6 is welded and fixed to the post 19 near the reinforcing plate 2 6. Specifically, it should be noted that the reinforcing plates 1 5 and 2 6 are both made of steel plates. The design of the reinforcing plates 1 5 and 2 6 increases the stability of the connection between the corrugated plate 2 14 and the two corrugated plates 3 15 and the fixed posts 11.

[0041] As one embodiment: two fixed columns 11 located on the top rear side of the base plate 1 are each hinged with a rear door 7. When the free ends of the two rear doors 7 are in contact, the two rear doors 7 can block the second gap 17. One of the columns 19 is hinged with a side door 8 for blocking the first gap 16. Through the design of the two rear doors 7, the second gap 17 on the rear side of the cargo box body 100 is blocked. Through the design of the side door 8, the first gap 16 on the right side of the cargo box body 100 is blocked.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
