Description

Technical Field

[0001] This utility model relates to the field of cargo box design, specifically to a cargo box structure. Background Technology

[0002] The cargo box is the part of a vehicle specifically designed for loading goods. It is designed to protect goods from the external environment and provide safe and efficient storage space.

[0003] The existing cargo box floor structure includes a floor plate, with crossbeams and longitudinal beams installed at the bottom of the floor plate in both width and length directions. It also includes longitudinal and transverse side beams around the floor plate. The longitudinal and transverse side beams are conventionally C-shaped channel steel, each containing a web with symmetrically fixed flanges on both sides. The web provides support and load-bearing capacity, while the flanges provide support and stability. A front fascia connects to the front of the floor plate, while side panels connect to the sides and rear. These side panels play a crucial role in preventing goods from falling out of the cargo box and may also have multiple functions such as hooks and flattening. During loading and unloading, existing cargo boxes use ropes to secure the goods. Since these ropes need to be wound, external hooks are installed on the crossbeams for hooking and securing the ropes, thus securing the goods.

[0004] The existing technology still has the following technical problems: First, the conventional installation of the bottom plate involves seamlessly welding the end of the crossbeam into the groove of the side beam. This welding structure prevents the electrophoretic liquid from entering the crossbeam for coating during the electrophoresis process, and the coating of the left and right cavities at the connection between the crossbeam and the longitudinal side beam is not thorough, resulting in weak corrosion resistance in the crossbeam and the longitudinal side beam. Second, when it rains, the top of the cargo box is often covered with a tarpaulin to prevent the goods from getting wet. However, there are gaps between the bottom of the side panels and the bottom plate, and rainwater will enter the bottom plate through the gaps, which will also cause the bottom of the goods to come into contact with the rainwater and wet the goods. Utility Model Content

[0005] The present invention aims to provide a cargo box structure to solve the problems of weak corrosion resistance of the floor and sideboard structures and easy damage to goods by rainwater.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cargo box structure, including a bottom plate, a side panel assembly rotatably connected to the bottom plate, a fixed beam at the bottom end of the bottom plate and a side beam at the edge, the upper flange of the side beam being vertically folded downward away from the web plate to form a first folded edge plate, the distance between the first folded edge plate and the web plate is less than the distance between the end of the lower flange and the web plate, the end of the fixed beam is embedded in the groove of the side beam and fixedly connected to the first folded edge plate, the top of the fixed beam is flush with the side beam, the outer side of the bottom end of the side panel assembly is convex downward and forms an L-shaped groove between it and the inner side of the bottom end of the side panel assembly for the end of the bottom plate to be embedded.

[0007] The beneficial effects of this solution are as follows: By setting the first folded edge plate on the edge beam, the end of the fixed beam cannot be seamlessly connected to the web of the edge beam when it is embedded in the edge beam. Instead, the end of the fixed beam is directly fixed to the first folded edge plate. This fixing structure creates a gap between the end of the fixed beam and the web of the edge beam, thereby ensuring that the electrophoretic liquid can fully pass through the gap between the two to coat the fixed beam and the edge beam during the electrophoretic process on the bottom plate structure, thus enhancing the corrosion resistance of the bottom plate structure.

[0008] The side panel assembly is rotatably connected to both ends and the rear end of the bottom plate. When the side panel assembly is rotated to vertical, it is perpendicular to the bottom plate. By setting an L-shaped groove at the bottom of the side panel assembly, with the L-shaped groove located on the side of the side panel assembly closer to the bottom plate and the protruding part located on the side of the side panel assembly away from the bottom plate, when the side panel assembly is rotated to vertical, both ends and the rear end of the bottom plate are embedded in the L-shaped groove of the side panel assembly. Compared with the prior art, rainwater on rainy days cannot enter the cargo compartment from the gap between the bottom end of the side panel assembly and the bottom plate, and therefore cannot flow onto the bottom plate. This effectively prevents rainwater from entering the cargo compartment through the gap between the side panel and the bottom plate and wetting the goods. It also eliminates the cause of bottom plate rust and prevents the bottom plate from easily rusting.

[0009] In the prior art, the ends of the fixed beam are completely embedded in the side beam. Therefore, the bottom plate and the upper flange of the side beam are both located at the top of the fixed beam. However, since the thickness of the side beam plate structure and the thickness of the bottom plate plate structure are different, a height difference will occur between the upper flange of the side beam and the bottom plate, forming a step, which will cause inconvenience in handling goods. In addition, in the prior art, the bottom plate is located below the transverse side beam and the main side beam, and the goods on the bottom plate are only supported by the weld points between the transverse beam and the side beam.

[0010] This invention proposes an installation structure for the fixed beam and side beam to address the corrosion problem between them. The fixed beam is embedded in the groove of the side beam and fixedly connected to the first folded edge plate. The tops of the fixed beam and side beam are kept in the same plane. Since the fixed beam is connected to the bottom of the base plate, the base plate is completely laid on top of the fixed beam and side beam. Therefore, compared to existing technologies, there is no height difference between the base plate and the side beam, eliminating the step problem. This corrosion-resistant installation structure also solves the step problem, ensuring the efficiency and safety of cargo handling within the cargo compartment. Furthermore, compared to existing technologies, in this solution, the base plate is located above the side beam, and the crossbeams and side beams are welded together. The base plate is supported by the crossbeams and longitudinal beams, as well as the weld points, thus improving its load-bearing capacity.

[0011] Furthermore, the fixed beam includes a crossbeam and a longitudinal beam, both of which are C-shaped channel steel. The longitudinal beam is fixedly connected to the bottom end of the crossbeam. The side beam includes a horizontal side beam and a longitudinal side beam. The horizontal side beam is fixed perpendicularly to the longitudinal side beam and the top of the horizontal side beam is flush with the top of the longitudinal side beam. A first folded edge plate is set on the longitudinal side beam. The end of the crossbeam is embedded in the groove of the longitudinal beam and fixedly connected to the first folded edge plate. The end of the longitudinal beam is fixedly connected to the horizontal side beam.

[0012] The beneficial effects of this solution are: by setting both the crossbeams and longitudinal beams as C-shaped channel steel, the lightweight design of the cargo box floor structure can be ensured.

[0013] Furthermore, the crossbeam opening is set upwards, and the ends of the left and right flanges of the crossbeam are set outwards horizontally to form a second folded edge plate, and the second folded edge plate and the flange of the crossbeam are set at rounded corners.

[0014] Furthermore, the guardrail assembly includes a guardrail body, which is an integrally bent design. A lower cavity is formed at the bottom of the guardrail body, and the lower cavity is convex outward on one side, forming an L-shaped groove at the bottom of the lower cavity.

[0015] Furthermore, it also includes a skirt plate connected to the side beam and a reinforcement member connected to the skirt plate, the reinforcement member having perforations that match the outer hook.

[0016] Furthermore, the reinforcement includes a reinforcing plate vertically fixedly connected to the skirt plate and a connecting plate fixedly connected to the reinforcing plate. The end of the connecting plate away from the reinforcing plate is fixedly connected to the crossbeam. The reinforcing plate and the connecting plate are arranged in a Y-shape. The perforation includes a first mating hole provided in the reinforcing plate and a second mating hole provided in the connecting plate.

[0017] Furthermore, the reinforcement part is located at the bifurcation of the Y-shaped structure, forming a channel for the outer hook to pass through through the first and second matching holes. The outer hook is provided with a protrusion at the hook head, and the width of the protrusion is greater than the width of the second matching hole.

[0018] Furthermore, an upper cavity is formed at the top of the railing body, a first groove is formed on the outer side of the railing body, and a second groove is formed on the inner side. A lock and several hooks are provided in the first groove, and several reinforcing ribs are provided in the second groove.

[0019] The beneficial effects of this solution are as follows: goods inside the cargo compartment are usually secured with ropes. In this case, the ropes can be passed through the hooks to facilitate the securing of the goods and increase the functionality of the sideboard. In addition, setting the hooks in the first groove can also make the sideboard structure more aesthetically pleasing.

[0020] Furthermore, the guardrail assembly also includes a post assembly connected to the end of the guardrail body, which is used to seal and reinforce the end of the guardrail body.

[0021] Furthermore, process holes for powering the flow of electrophoretic fluid are provided at the rounded corners of the second folded plate, the bottom ends of the upper and lower cavities, the column assembly, both sides of the reinforcing rib, and the front. Attached Figure Description

[0037] Example

[0038] The basic implementation examples are as follows: Figure 1-13 As shown, Figures 1-6The cargo box structure shown includes a floor plate 1, with a front enclosure 11 fixedly installed at the front end of the floor plate 1. Side panel assemblies are rotatably connected to the sides and rear end of the floor plate 1. Each side panel assembly includes a side panel body and a column assembly connected to the end of the side panel body. The side panel body includes a side panel body 23 and a rear panel body 32. The column assembly includes a front column assembly 21, a rear column assembly 22, and a side column assembly 31. The front column assembly 21 and the rear column assembly 22 are respectively connected to the front and rear of the side panel body 23. The two ends form the side plate assembly 2, and the side column assembly 31 is connected to both ends of the rear plate body 32 to form the rear plate assembly 3. The side plate body 23 and the rear plate body 32 have the same cross-sectional shape and size. Both the side plate body 23 and the rear plate body 32 are integrally bent from sheet metal. The top of both the side plate body 23 and the rear plate body 32 has an upper cavity 4, and the bottom of both has a lower cavity 5. When the side plate body 23 and the rear plate body 32 are bent, the lower cavity 5 is bent outward and downward. An L-shaped groove is formed between the downward protruding side and the inward side of the lower cavity 5. The bottom ends of the side plate body 23 and the rear plate body 32 are rotatably connected by hinges. The hinges are welded to the end of the bottom plate 1 and the bottom end of the inward side of the lower cavity 5, respectively. When the side plate body 23 is rotated to a vertical position, the end of the bottom plate 1 is embedded in the L-shaped groove. The protruding part of the lower cavity 5 is lower than the plane of the bottom plate 1, which prevents rainwater from entering the bottom plate 1 through the gap between the bottom plate 1 and the side plate body 23 during rainy days, avoids the goods from contacting rainwater, prevents the goods from getting wet, and effectively prevents the bottom plate 1 from corroding and rusting. At the same time, the seamless connection between the cargo box side panel and the bottom plate 1 is more aesthetically pleasing when viewed from the side and rear. Process holes 9 for the flow of electrophoretic liquid are opened at the bottom ends of the upper cavity 4 and the lower cavity 5. The design of the process holes 9 at the bottom end is conducive to better flow and discharge of electrophoretic liquid during the electrophoresis process, which greatly improves the corrosion resistance of the side plate body 23 and the rear plate body 32. Moreover, the process holes 9 are located at the bottom and do not affect the appearance of the side panel.

[0039] like Figures 2-6As shown, the portions of the side panel body 23 and the rear panel body 32 located between the upper cavity 4 and the lower cavity 5 are formed by bending, with a first groove 6 formed on the outer side and a second groove 7 formed on the inner side. Several hooks 62 are evenly distributed within the first groove 6. A latch 61 is installed at the end of the first groove 6 of the side panel body 23 near the front fascia 11. Latches 61 are also installed at both ends of the rear panel body 32 within the first groove 6. A latch mounting plate is bolted to the opposite side of the first groove 6, with the bolt ends connected to the base of the latch 61, thus installing the latch 61 within the first groove 6. Neither the hooks 62 nor the latches 61 protrude from the first groove 6, allowing the side panel to... The main body 23 and the rear plate main body 32 are more aesthetically pleasing. Several reinforcing ribs 71 are welded at equal intervals in the second groove 7 and are resistance welded to the inner side of the side plate main body 23 and the rear plate main body 32. The outline of the reinforcing ribs 71 near the second groove 7 is completely fitted with the shape of the side plate main body 23 and the rear plate main body 32. The reinforcing ribs 71 strengthen the side plate. Several reinforcing ribs 71 divide the side plate main body 23 and the rear plate main body 32 into several adjacent grooves, which strengthens the side plate main body 23 and the rear plate main body 32. Process holes 9 are also opened on both sides and the front of the reinforcing ribs 71, which can improve the coating effect inside the reinforcing ribs 71 and improve the corrosion resistance.

[0040] like Figures 3-5 As shown, a first locking hook 111 is fixedly welded to the front fascia 11. Both the front pillar reinforcement plate 212 and the side plate body 23 are provided with first locking holes 24 for the first locking hook 111 to pass through. The first locking holes 24 of the two are connected. When the side plate body 23 is rotated to a vertical position, the first locking hook 111 passes through the first locking hole 24 in sequence through the front pillar reinforcement plate 212 and the side plate body 23 and protrudes from the first groove 6. At this time, the first locking hook 111 corresponds to the locking buckle 61 on the side plate body 23. The first locking hook 111 and the locking buckle 61 are engaged to achieve the purpose of vertically fixing the side plate body 23. A second locking hook 2221 is welded to the rear pillar reinforcement plate 222. The rear pillar body 221 is provided with a second locking hole 2211 for installing the second locking hook 2221.

[0041] like Figure 4As shown, the side pillar assembly 31 includes a side pillar body 311 welded to the end of the rear plate body 32. The side pillar body 311 seals and reinforces the rear plate assembly 3. It also includes a side pillar reinforcing plate 312 welded to the inner side of the end of the rear plate assembly 3. The side pillar reinforcing plate 312 further seals and reinforces the end of the rear plate body 32. Both the side pillar body 311 and the side pillar reinforcing plate 312 are provided with process holes 9 to further improve the corrosion resistance of the rear plate body 32. Connectors 8 are welded to opposite sides of the rear pillar reinforcing plate 222 and the side pillar body 311. The connectors 8 are configured as follows: Welded nuts are detachably connected by a cable 81. When the rear plate body 32 is rotated to a vertical position, the latch 61 on the rear plate body 32 corresponds to and engages with the second locking hook 2221, which can achieve the purpose of vertically fixing the rear plate body 32. At this time, the cable 81 is in a slack state. When the rear plate body 32 needs to be rotated to a horizontal position and goods need to be placed, simply connect the cable 81 between the welded nuts to achieve the flat setting of the rear plate body 32. The setting of the cable 81 allows the rear plate body 32 to be flattened, which is beneficial to the loading and unloading of goods and increases the function of the panel structure.

[0042] like Figures 7-8 As shown, the fixed beam 02 is a beam fixedly installed at the bottom end of the base plate 1, including several crossbeams 021 fixedly welded to the bottom end of the base plate 1 in the width direction, and longitudinal beams 022 equally and symmetrically welded to both sides of the bottom end of the crossbeams 021. The cross-sectional shape of the crossbeams 021 is the same as that of the C-shaped channel steel, and includes a web and flanges vertically fixed to both sides of the web. The crossbeams 021 are set with the opening facing upwards. The flanges on the left and right sides of the crossbeams 021 are set with outward horizontal flanges, forming a second flange plate 0211. The top of the second flange plate 0211 is fixedly welded to the bottom end of the base plate 1. The second flange plate 0211 and the left and right flanges of the crossbeams 021 are set with rounded corners, and process holes 9 for the flow of electrophoretic liquid are opened at the rounded corners. The base plate 1 is spliced ​​from two patterned plates of the same size and thickness. The longitudinal beams 022 and the base plate The longitudinal beam 022 has the same length direction as the crossbeam 021, and its cross section is the same as that of the C-shaped channel steel. The web of the longitudinal beam 022 is set perpendicular to the web of the crossbeam 021. The upper flange of the longitudinal beam 022 is fixedly welded to the web of the crossbeam 021. A first reinforcing block 023 is fixedly welded between the two webs of the crossbeam 021 and the longitudinal beam 022. The first reinforcing block 023 is hollow to facilitate the flow of the electrophoretic liquid. The first reinforcing block 023 is triangular in design to stabilize and strengthen the connection between the two. A second reinforcing block 024 is embedded in the groove of the longitudinal beam 022. The second reinforcing block 024 is also hollow to facilitate the flow of the electrophoretic liquid. The second reinforcing block 024 is fixedly welded to the longitudinal beam 022. The second reinforcing block 024 enhances the load-bearing and support performance of the longitudinal beam 022.

[0043] like Figures 9-11As shown, the side beam 01 is a beam arranged around the base plate 1. The side beam 01 includes a longitudinal side beam 012 located along the length of the base plate 1 and a transverse side beam 011 located along the width of the base plate 1. The cross-sections of the longitudinal side beam 012 and the transverse side beam 011 are the same as the cross-sectional shape of the C-shaped channel steel. Here, it is assumed that the width between the outer sides of the two flanges of the C-shaped channel steel is called the channel width. In this embodiment, the channel width of the longitudinal side beam 012 is greater than the channel width of the transverse side beam 011, and the difference in channel width between the longitudinal side beam 012 and the transverse side beam 011 is the same as the plate thickness of the transverse side beam 011. In this embodiment, when fixing the transverse side beam 011 and the longitudinal side beam 012, the webs of both are vertically arranged. The upper flanges at both ends of the transverse beam 011 are cut with notches for the longitudinal beam 012 to fit into. The width of the notches is equal to the groove depth of the longitudinal beam 012. The lower flange of the transverse beam 011 is adapted to avoid the thickness of the web of the longitudinal beam 012. The end of the longitudinal beam 012 is embedded into the groove of the transverse beam 011. The lower flange of the longitudinal beam 012 is fixedly welded to the lower flange of the transverse beam 011. At this time, the upper flange of the longitudinal beam 012 is embedded in the notch of the upper flange of the transverse beam 011. At the same time, the web of the transverse beam 011 seals the end of the longitudinal beam 012. The gap is welded by welding rod, thus achieving the vertical fixation of the transverse beam 011 and the longitudinal beam 012.

[0044] like Figure 11 As shown, the upper flange of the longitudinal beam 012 is vertically flanged downwards to form a first flange plate 0121. The distance between the first flange plate 0121 and the web of the longitudinal beam 022 is less than the distance between the lower flange of the longitudinal beam 022 and the web. When the end of the crossbeam 021 is inserted into the groove of the longitudinal beam 012 and welded, the end of the crossbeam 021 abuts against the first flange plate 0121 before touching the bottom. At this time, the end of the crossbeam 021 is fixedly welded to the first flange plate 0121. After welding, the top of the crossbeam 021 is flush with the longitudinal beam 012. The tops of beams 011 and 012 are on the same plane. Since the tops of beams 011 and 012 are also on the same plane, the bottom surface of the base plate 1 is in contact with the tops of beams 011 and 012. The beams 011 and 012 are fixedly welded to the base plate 1 by welding, thereby eliminating the phenomenon of steps between the base plate 1 and the beams 01, increasing the safety of goods handling. At the same time, the gap between the longitudinal beams 012 and the beams 021 allows the electrophoretic liquid to enter the coating, enhancing the corrosion resistance.

[0045] like Figure 12-13As shown, it also includes a skirt panel 03, which includes a curved panel 033, an upper folding plate 031 horizontally arranged at the upper end of the curved panel 033, and a lower folding plate 032 horizontally arranged at the bottom end of the curved panel 033. The curved panel 033 is used to install on both sides of the bottom end of the cargo box. The curved panel 033 protrudes outward to both sides of the cargo box. Several reinforcing plates 041 are vertically welded on the curved panel 033. The reinforcing plates 041 are bent. The bending direction of the reinforcing plates 041 is the same as the bending direction of the curved panel 033, and the bending line of the reinforcing plates 041 is consistent with the bending line of the curved panel 033. The reinforcing plates 041 are in contact with the inner surface of the curved panel 033.

[0046] like Figure 12-13 As shown, external hooks 0212 are welded to both ends of the crossbeam 021. Several crossbeams 021 correspond one-to-one with several reinforcing plates 041. A connecting plate 042 is provided between the crossbeam 021 and the reinforcing plate 041. The connecting plate 042 includes a first fixing plate 0422 horizontally set at the top and a second fixing plate 0423 vertically set at the bottom. The first fixing plate 0422 can be welded to the crossbeam 021 or fixed by bolts. In this scheme, bolt connection is preferred. The second fixing plate 0423 can be welded to the corresponding reinforcing plate 041 or bolted. In this scheme, welding is preferred. An inclined plate 0424 is provided between the first fixing plate 0422 and the second fixing plate 0423. The inclined plate 0424 is integrally formed with the first fixing plate 0422 and the second fixing plate 0423. The reinforcing plate 041 and the connecting plate 042 are connected in a Y-shaped arrangement.

[0047] like Figure 12-13 As shown, the top of the reinforcing plate 041 has a first mating hole 0411, and the connecting plate 042 has a second mating hole 0421 located at the inclined plate 0424. The first mating hole 0411 and the second mating hole 0421 are collectively referred to as through holes. In order to accommodate the shape of the outer hook 0212, the first mating hole 0411, the second mating hole 0421, and the Y-shaped bifurcation together form a channel for the outer hook 0212 to pass through. There is a gap at the connection between the top of the reinforcing plate 041 and the skirt plate 03 for the outer hook 0212 to pass through. The upper folding plate 031 has the same width as the longitudinal side beam 012. At the same time, the bottom end of the longitudinal side beam 012 and the upper folding plate 031 are provided with several corresponding threaded holes. The upper folding plate 031 and the longitudinal side beam 012 are fixedly connected by bolts. A protrusion 0213 is welded at the hook head of the outer hook 0212 with welding rod. The width of the protrusion 0213 is greater than the width of the second matching hole 0421 to prevent the outer hook 0212 from sliding out of the second matching hole 0421 due to vibration during the driving process.

[0048] like Figure 12-13As shown, the upper and lower ends of the reinforcing plate 041 are also provided with folded plates, which correspond to the upper folded plate 031 and the lower folded plate 032 of the skirt plate 03, respectively. The folded plates of the reinforcing plate 041 and the folded plates of the skirt plate 03 can be fixed by welding or by bolts. In this scheme, the width of the reinforcing plate 041 is set to correspond exactly to the two adjacent threaded holes on the upper folded plate 031. Therefore, threaded holes are also provided at the upper folded plate of the reinforcing plate 041. By passing bolts through the reinforcing plate 041, the upper folded plate 031 and the longitudinal beam 012 in sequence, the reinforcing plate 041 can be fixed to the skirt plate 03, and the upper folded plate 031 can be fixed to the longitudinal beam 012.
