Description

Technical Field

[0001] The invention relates to the field of cargo compartment design, and in particular to a cargo compartment structure. Background Art

[0002] The cargo box is the portion of the vehicle dedicated to carrying cargo, designed to protect the cargo from the outside environment and provide safe and efficient storage space.

[0003] The existing cargo compartment floor structure includes a bottom plate, and the width and length directions of the bottom end of the bottom plate are respectively provided with a cross beam and a longitudinal beam, and also includes longitudinal side beams and transverse side beams arranged around the bottom plate. The longitudinal side beams and transverse side beams are generally arranged in the shape of a C-shaped channel steel. The C-shaped channel steel includes a web plate, and wing plates are symmetrically fixed on both sides of the web plate. The web plate plays a supporting and load-bearing role, and the wing plates play a supporting and stabilizing role. The front end of the bottom plate is connected to the front enclosure, and the sides and rear end of the bottom plate are connected to the guardrails. The guardrails play an important role in preventing the goods from falling from the cargo compartment, and can also have multiple functions such as hooks and guardrails. In the process of loading goods in the existing cargo compartment, ropes are used to fix the goods in the cargo compartment. The ropes need to be hung and wound, so an outer hook is set on the crossbeam, and the ropes are hung and fixed through the outer hooks to achieve the fixation of the goods.

[0004] The prior art still has the following technical problems: first, the conventional installation of the bottom plate is to embed the end of the crossbeam into the groove of the side beam for seamless welding. This welding structure will prevent the electrophoretic liquid from entering the crossbeam for coating during the electrophoretic 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, a tarpaulin is often used to cover the top of the cargo compartment to prevent the cargo from getting wet, but there is a gap between the bottom end of the railing and the bottom plate, and rainwater will enter the bottom plate along the gap, and the bottom of the cargo will also come into contact with the rainwater, thereby wetting the cargo. Summary of the invention

[0005] The present invention is intended to provide a cargo compartment structure to solve the problem that the bottom plate and sideboard structures have weak corrosion resistance and the cargo is easily wetted by rain.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a cargo compartment structure, including a bottom plate, which is rotatably connected to a guardrail assembly, a fixed beam is arranged at the bottom end of the bottom plate, a side beam is arranged at the edge, and an upper wing plate of the side beam is vertically flanged downward at one end away from the web plate to form a first folded edge plate, and the distance between the first folded edge plate and the web plate is smaller than the distance between the end of the lower wing plate and the web plate, the end of the fixed beam is embedded in the groove of the side beam and is 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 guardrail assembly is convex downward, and an L-shaped groove for the end of the bottom plate to be embedded is formed between the inner side of the bottom end of the guardrail assembly.

[0007] The beneficial effect of this solution is as follows: a first folded edge plate is provided on the side beam so that when the fixed beam is embedded in the side beam, its end cannot be seamlessly connected to the web of the side beam, but the end of the fixed beam is directly fixedly connected to the first folded edge plate. This fixed structure allows a gap to exist between the end of the fixed beam and the web of the side beam, thereby ensuring that when the bottom plate structure is subjected to the electrophoretic process, the electrophoretic liquid can fully pass through the gap between the two to coat the fixed beam and the side beam, thereby enhancing the corrosion resistance of the bottom plate structure.

[0008] The sidearm assembly is rotatably connected to both ends and the rear end of the bottom plate. When the sidearm assembly is rotated to vertical, the sidearm assembly is perpendicular to the bottom plate. An L-shaped groove is provided at the bottom end of the sidearm assembly, and the L-shaped groove is located on the side of the sidearm assembly close to the bottom plate, and the convex part is located on the side of the sidearm assembly away from the bottom plate. Therefore, when the sidearm assembly is rotated to vertical, both ends and the rear end of the bottom plate are embedded in the L-shaped groove of the sidearm assembly. Compared with the prior art, rainwater on rainy days cannot enter the cargo compartment from the gap between the bottom end of the sidearm assembly and the bottom plate, and cannot flow onto the bottom plate, thereby effectively preventing rainwater from entering the cargo compartment through the gap between the sidearm and the bottom plate and wetting the goods. At the same time, the inducement for rusting of the bottom plate is eliminated, and the phenomenon of rusting of the bottom plate can be prevented.

[0009] In the prior art, the end of the fixed beam is completely embedded in the side beam, so the bottom plate and the upper wing plate of the side beam are both located at the top of the fixed beam. Since the thickness of the side beam plate structure and the thickness of the bottom plate plate structure are different, there will be a height difference between the upper wing plate of the side beam and the bottom plate, forming a step, which brings inconvenience to the transportation of goods. In addition, in the prior art, the bottom plate is located below the transverse side beam and the total side beam, and the goods on the bottom plate are only carried by the welding points between the transverse beam and the side beam.

[0010] In order to solve the anti-corrosion problem between the fixed beam and the side beam, the present invention proposes an installation structure for the fixed beam and the side beam, that is, the fixed beam is embedded in the groove of the side beam and fixedly connected to the first folding plate, and at the same time, the top ends of the fixed beam and the side beam are maintained in the same plane. Since the fixed beam is connected to the bottom end of the bottom plate, from the perspective of the structural orientation, the bottom plate is completely laid on the top ends of the fixed beam and the side beam. Therefore, compared with the prior art, there is no height difference between the bottom plate and the side beam, and no steps are formed. Therefore, the anti-corrosion installation structure also solves the step problem, and can ensure the efficiency and safety of handling goods in the cargo compartment. In addition, compared with the prior art, the bottom plate in this solution is located above the side beam, and the cross beam and the side beam are welded, so that the bottom plate is supported by the support of the cross beam and the longitudinal beam and the welding points, thereby improving the bearing capacity of the bottom plate.

[0011] Furthermore, the fixed beam includes a transverse beam and a longitudinal beam, both of which are arranged in a C-shaped channel steel shape, the longitudinal beam is fixedly connected to the bottom end of the transverse beam, the side beam includes a transverse side beam and a longitudinal side beam, the transverse side beam is vertically fixed to the longitudinal side beam, the transverse side beam is flush with the top of the longitudinal side beam, the first folding plate is arranged on the longitudinal side beam, the end of the transverse beam is embedded in the groove of the longitudinal beam and is fixedly connected to the first folding plate, and the end of the longitudinal beam is fixedly connected to the transverse side beam.

[0012] The beneficial effect of this solution is that by setting both the cross beam and the longitudinal beam to be C-shaped channel steel, the lightweight of the cargo compartment floor structure can be ensured.

[0013] Furthermore, the cross beam opening is arranged upward, and the left and right wing plate ends of the cross beam are arranged to be horizontally flanged outward to form a second folded edge plate, and a rounded corner is arranged between the second folded edge plate and the wing plate of the cross beam.

[0014] Furthermore, the guardrail assembly includes a guardrail body, which is an integrated bent-molded design. A lower cavity is formed at the bottom end of the guardrail body. The inner side of the lower cavity is convex downwardly facing outward, forming an L-shaped groove at the bottom end of the lower cavity.

[0015] Furthermore, it also includes a skirt plate connected to the side beam and a reinforcing member connected to the skirt plate, and the reinforcing member is provided with a through hole matching the outer hook.

[0016] Furthermore, the reinforcement member includes a reinforcing plate vertically fixedly connected to the skirt plate and a connecting plate fixedly connected to the reinforcing plate, one end of the connecting plate away from the reinforcing plate is fixedly connected to the cross beam, the reinforcing plate and the connecting plate are arranged in a Y shape, and the perforations include a first matching hole set in the reinforcing plate and a second matching hole set in the connecting plate.

[0017] Furthermore, the first anastomotic hole and the second anastomotic hole are irregular in shape, and the reinforcement piece is located at the bifurcation of the Y-shaped structure to form a channel for the outer hook to pass through the first anastomotic hole and the second anastomotic hole. 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 anastomotic hole.

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

[0019] The beneficial effects of this solution are: the goods in the cargo compartment are usually fixed with ropes, and the ropes can be passed through the hooks to facilitate the fixation of the goods and increase the function of the railing. In addition, setting the hook in the first groove can also make the railing structure more beautiful.

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

[0021] Furthermore, process holes for allowing electrophoresis liquid to flow are provided at the rounded corners of the second folding plate, the bottom ends of the upper cavity and the lower cavity, the column assembly, and both sides and the front of the reinforcing ribs.

[0037] Example

[0038] The embodiment is basically as shown in the attached Figure 1-13 As shown, Figure 1-Figure 6The cargo compartment structure shown in the figure includes a bottom plate 1, a front enclosure 11 is fixedly arranged at the front end of the bottom plate 1, and a guardrail assembly is rotatably connected to the two sides and the rear end of the bottom plate 1. The guardrail assembly includes a guardrail body, a column assembly connected to the end of the guardrail body, the guardrail body includes a side plate body 23 and a rear plate body 32, and 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 plate body 23. The two ends form a side panel assembly 2, and the side column assembly 31 is connected to the two ends of the rear panel body 32 to form a rear panel assembly 3. The cross-sectional shape and size of the side panel body 23 and the rear panel body 32 are exactly the same. The side panel body 23 and the rear panel body 32 are both designed to be bent into a sheet material in one piece. The top ends of the side panel body 23 and the rear panel body 32 are formed with an upper cavity 4 and the bottom ends are formed with a lower cavity 5. When the side panel body 23 and the rear panel body 32 are bent, the inner side of the lower cavity 5 is bent downwardly to the outside. An L-shaped groove is formed between the downward protruding side and the inward side of the lower cavity 5, and the bottom ends of the side panel body 23 and the rear panel body 32 are rotatably connected by hinges, and the hinges are respectively welded to the end of the bottom plate 1 and the bottom end of the inward side of the lower cavity 5. When the side panel body 23 is rotated to vertical, the end of the bottom plate 1 is embedded in the L-shaped groove, and 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 panel body 23 on rainy days, avoids contact between the goods and rainwater, and prevents the goods from getting wet. At the same time, it can effectively prevent the bottom plate 1 from corroding and rusting. At the same time, it is more beautiful to see the cargo compartment railing and the bottom plate 1 without gaps from the side and the 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 process holes 9 are designed at the bottom to facilitate better flow in and discharge of the electrophoretic liquid during the electrophoresis coating process, greatly improving the corrosion resistance of the side panel body 23 and the rear panel body 32, and the process holes 9 are located at the bottom and do not affect the appearance of the railings.

[0039] like Figure 2-Figure 6As shown, the part of the side panel body 23 and the rear panel body 32 located between the upper cavity 4 and the lower cavity 5 is formed by bending, and a first groove 6 is formed on the outside and a second groove 7 is formed on the inside respectively, and a plurality of hooks 62 are evenly distributed in the first groove 6, and a lock buckle 61 is installed at the end of the first groove 6 of the side panel body 23 close to the front wall 11, and the two ends of the rear panel body 32 are located in the first groove 6 and also installed with lock buckles 61, and the opposite side of the first groove 6 is connected with a lock buckle mounting plate by bolts, and the end of the bolt is connected to the base of the lock buckle 61, so that the lock buckle 61 is installed in the first groove 6, and the hook 62 and the lock buckle 61 do not protrude from the first groove 6, so that the side panel The main body 23 and the rear panel main body 32 are more beautiful, and a number of reinforcing ribs 71 are welded at equal intervals in the second groove 7, which are welded to the inner sides of the side panel main body 23 and the rear panel main body 32 through resistance welding, and the contour of the reinforcing rib 71 close to the second groove 7 is completely in line with the shape of the side panel main body 23 and the rear panel main body 32, and the reinforcing rib 71 strengthens the railings. A number of reinforcing ribs 71 divide the side panel main body 23 and the rear panel main body 32 into a number of adjacent grooves, which strengthens the side panel main body 23 and the rear panel main body 32, and process holes 9 are also opened on both sides and the front of the reinforcing rib 71, which can improve the coating effect inside the reinforcing rib 71 and enhance the corrosion resistance.

[0040] like Figure 3-Figure 5 As shown, the front enclosure 11 is fixedly welded with a first locking hook 111, and the front pillar reinforcement plate 212 and the side panel body 23 are both provided with a first locking hole 24 for the first locking hook 111 to pass through, and the first locking holes 24 of the two are connected. When the side panel body 23 is rotated to vertical, the first locking hook 111 passes through the front pillar reinforcement plate 212 and the side panel body 23 in sequence through the first locking hole 24 and protrudes from the first groove 6. At this time, the first locking hook 111 corresponds to the locking buckle 61 on the side panel body 23, and the first locking hook 111 is buckled with the locking buckle 61 to achieve the purpose of vertically fixing the side panel body 23. The rear pillar reinforcement plate 222 is welded with a second locking hook 2221, and 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 strengthens the rear plate assembly 3, and also includes a side pillar reinforcement plate 312 welded to the inner side of the end of the rear plate assembly 3, the side pillar reinforcement plate 312 further seals and strengthens the end of the rear plate body 32, the side pillar body 311 and the side pillar reinforcement plate 312 are also provided with process holes 9, further improving the corrosion resistance of the rear plate body 32, and the rear pillar reinforcement plate 222 and the side pillar body 311 are welded with a connecting piece 8 on the opposite side, and the connecting piece 8 is set Welding nuts, and a cable 81 is detachably connected between the welding nuts. When the rear plate body 32 is rotated to vertical, the lock buckle 61 on the rear plate body 32 corresponds to and buckles with the second lock hook 2221, which can achieve the purpose of vertically fixing the rear plate body 32. At this time, the cable 81 is in a relaxed state. When the rear plate body 32 needs to be rotated to horizontal and cargo is placed, it is only necessary to connect the cable 81 between the welding nuts, which can achieve the flat setting of the rear plate body 32. The setting of the cable 81 enables the rear plate body 32 to be laid flat, which is beneficial to the loading and unloading of cargo and increases the function of the railing structure.

[0042] like Figure 7-Figure 8 As shown, the fixed beam 02 is a beam fixedly set at the bottom end of the bottom plate 1, including a plurality of cross beams 021 fixedly welded to the width direction of the bottom end of the bottom plate 1, and longitudinal beams 022 equally and symmetrically welded to both sides of the bottom end of the cross beam 021. The cross beam 021 has the same cross section shape as the C-shaped channel steel, and includes a web and wing plates vertically fixed to both sides of the web. The cross beam 021 is opened and set upward, and the wing plates on the left and right sides of the cross beam 021 are horizontally flanged outward, and the horizontal flange forms a second flange plate 0211. The top end of the second flange plate 0211 is fixedly welded to the bottom end of the bottom plate 1, and the second flange plate 0211 is rounded between the left and right wing plates of the cross beam 021, and a process hole 9 for the flow of electrophoretic liquid is opened at the rounded corner. The bottom plate 1 is spliced ​​by two patterned plates of the same size and thickness, and the longitudinal beam 022 and the bottom plate 1, the cross section of the longitudinal beam 022 is also the same as the cross section of the C-shaped channel steel, the web of the longitudinal beam 022 is perpendicular to the web of the cross beam 021, the upper wing plate of the longitudinal beam 022 is fixedly welded to the web of the cross beam 021, and a first reinforcing block 023 is fixedly welded between the two webs of the cross beam 021 and the longitudinal beam 022. The first reinforcing block 023 is hollow, which is convenient for increasing the fluidity of the electrophoretic liquid, and the first reinforcing block 023 is triangular in design, which can stabilize and strengthen the connection between the two. A second reinforcing block 024 is embedded in the groove of the longitudinal beam 022, and the second reinforcing block 024 is also hollow. In order to facilitate enhancing the flow of the electrophoretic liquid, the second reinforcing block 024 is fixedly welded to the longitudinal beam 022, and the second reinforcing block 024 enhances the load-bearing and supporting performance of the longitudinal beam 022.

[0043] like Figure 9-11As shown, the side beam 01 is a beam arranged around the bottom plate 1. The side beam 01 includes a longitudinal side beam 012 located in the length direction of the bottom plate 1 and a transverse side beam 011 located in the width direction of the bottom plate 1. The cross-sections of the longitudinal side beam 012 and the transverse side beam 011 are also the same as the cross-section shape of the C-shaped channel steel. It is assumed here that the width between the outer sides of the fenders on both sides 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 the transverse side beam 011 and the longitudinal side beam 012 are fixed, the webs of both are vertically arranged. The upper wing plates at both ends of the transverse side beam 011 are cut with notches for the longitudinal side beam 012 to fit into, and the width of the notch is equal to the groove depth of the longitudinal side beam 012. The end of the lower wing plate of the transverse side beam 011 is adaptively cut to avoid the thickness of the web of the longitudinal side beam 012, and the end of the longitudinal side beam 012 is embedded in the groove of the transverse side beam 011, and the lower wing plate of the longitudinal side beam 012 is fixed and welded to the lower wing plate of the transverse side beam 011. At this time, the upper wing plate of the longitudinal side beam 012 is embedded in the notch of the upper wing plate of the transverse side beam 011, and at the same time, the web of the transverse side beam 011 seals the end of the longitudinal side beam 012, and the gap is welded by welding rods to achieve vertical fixation of the transverse side beam 011 and the longitudinal side beam 012.

[0044] like Fig.11 As shown, the upper wing plate end of the longitudinal side beam 012 is vertically turned downward to form a first folding plate 0121. The distance between the first folding plate 0121 and the web of the longitudinal beam 022 is smaller than the distance between the lower wing plate of the longitudinal beam 022 and the web. When the end of the cross beam 021 is embedded in the groove of the longitudinal side beam 012 and welded, the end of the cross beam 021 is against the first folding plate 0121 before it touches the bottom. At this time, the end of the cross beam 021 is fixedly welded to the first folding plate 0121. After welding, the top of the cross beam 021 is aligned with the longitudinal beam 012. The tops of the transverse side beams 011 and the longitudinal side beams 012 are in the same plane, and since the tops of the transverse side beams 011 and the longitudinal side beams 012 are also in the same plane, the bottom surface of the bottom plate 1 is in contact with the tops of the transverse side beams 011 and the longitudinal side beams 012. The transverse side beams 011 and the longitudinal side beams 012 are fixed to the bottom plate 1 by welding, thereby eliminating the phenomenon of steps between the bottom plate 1 and the side beams 01, increasing the safety during cargo handling, and at the same time, the gap between the longitudinal side beams 012 and the transverse beam 021 can facilitate the electrophoretic liquid to enter the coating, thereby enhancing the corrosion resistance.

[0045] like Figure 12-13As shown, it also includes a skirt plate 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 be installed on both sides of the bottom end of the cargo box. The curved panel 033 is convexly arranged on both sides of the cargo box. A plurality of reinforcing plates 041 are vertically welded on the curved panel 033. The reinforcing plate 041 is bent, and the bending direction of the reinforcing plate 041 is the same as the bending direction of the curved panel 033, and the bending line shape of the reinforcing plate 041 is consistent with the bending line shape of the curved panel 033, and the reinforcing plate 041 is in contact with the inner surface of the curved panel 033.

[0046] like Figure 12-13 As shown, outer hooks 0212 are welded at both ends of the crossbeam 021, and a plurality of crossbeams 021 correspond to a plurality of reinforcing plates 041 one by one. A connecting plate 042 is arranged between the crossbeam 021 and the reinforcing plate 041. The connecting plate 042 includes a first fixing plate 0422 arranged horizontally at the top and a second fixing plate 0423 arranged vertically at the bottom. The first fixing plate 0422 and the crossbeam 021 can be welded or fixedly connected by bolts, and the present scheme is preferably bolted. The second fixing plate 0423 and the corresponding reinforcing plate 041 can be welded or bolted, and the present scheme is preferably welded. An inclined plate 0424 is arranged between the first fixing plate 0422 and the second fixing plate 0423, and the inclined plate 0424 is integrally formed with the first fixing plate 0422 and the second fixing plate 0423. The reinforcing plate 041 is connected to the connecting plate 042 in a Y-shaped arrangement.

[0047] like Figure 12-13 As shown, the top of the reinforcing plate 041 is provided with a first anastomotic hole 0411, and the connecting plate 042 is provided with a second anastomotic hole 0421 at the inclined plate 0424. The shapes of the first anastomotic hole 0411 and the second anastomotic hole 0421 are irregular. The first anastomotic hole 0411 and the second anastomotic hole 0421 are collectively referred to as perforations. In order to adapt to the shape of the outer hook 0212, the first anastomotic hole 0411, the second anastomotic hole 0421 and the Y-shaped bifurcation together form a channel for the outer hook 0212 to pass through. The reinforcing plate 041 is connected to the top of the skirt plate 03. There is a gap for the outer hook 0212 to pass through; the width of the upper folding plate 031 is the same as the width of the longitudinal side beam 012, and at the same time, the bottom end of the longitudinal side beam 012 and the upper folding plate 031 are provided with a number of corresponding threaded holes, and the upper folding plate 031 and the longitudinal side beam 012 are fixedly connected with bolts, and a protrusion 0213 is welded at the hook head of the outer hook 0212 with welding rods. 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 in the opposite direction due to vibration during driving.

[0048] like Figure 12-13As shown, folding plates are also provided at the upper and lower ends of the reinforcing plate 041, and they correspond to the upper folding plate 031 and the lower folding plate 032 of the skirt plate 03 respectively. The folding plates of the reinforcing plate 041 and the folding plates of the skirt plate 03 can be fixed by welding or by bolts.
