Detailed Implementation

[0030] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0031] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0032] like Figure 1-8 As shown, this utility model provides a cargo box brim 1, including an arched plate 7, a pair of side baffles 8, a front baffle 5, and a reinforcing rib 6. The pair of side baffles 8 are respectively disposed at both ends of the arched plate 7 along the arc direction, the front baffle 5 is disposed at one end of the arched plate 7 along the length direction, and the reinforcing rib 6 is disposed at the bottom of the arched plate 7.

[0033] In the above technical solution, the cargo box brim 1 includes an arch-shaped plate 7, a front baffle 5, a pair of opposing side baffles 8, and reinforcing ribs 6. The structure of the arch-shaped plate 7 can be an arc-shaped arch structure, or it can be an arch-shaped structure formed by multiple folds (such as...). Figure 8 As shown), the upper parts of the opposite side walls of a pair of side baffles 8 are respectively connected (e.g., welded) to the ends of the arched plate 7 along its arc direction. The shape of the front baffle 5 is consistent with the arc cross-sectional shape of the arched plate 7, so that the front baffle 5 is connected (e.g., welded) to one end of the arched plate 7 along its length direction. The other end of the arched plate 7 away from the front baffle 5 is the mounting end for connection with the cargo box.

[0034] The reinforcing rib 6 is provided at the bottom of the arch-shaped plate 7. The reinforcing rib 6 is arranged along the arc direction of the arch-shaped plate 7. Preferably, there are multiple reinforcing ribs 6. The multiple reinforcing ribs 6 can be arranged at intervals along the arc direction of the arch-shaped plate 7, or at intervals along the length direction of the arch-shaped plate 7, or arranged in a grid pattern along both the arc direction and the length direction of the arch-shaped plate 7. The specific arrangement depends on the actual situation.

[0035] It should be noted that the length direction of the arch-shaped plate 7 refers to the direction of the perpendicular line connecting the two ends of the arch-shaped plate 7, excluding the two ends along the arc direction. Figure 1 If the front baffle 5 is on the left side, then the length direction of the arch-shaped plate 7 is... Figure 1 The direction is from left to right / from right to left; in actual use, the arch-shaped plate 7, as well as the front baffle 5, side baffle 8, and reinforcing rib 6, can be made of high-strength alloy steel, aluminum alloy, or composite materials, and the weight, cost, and durability are weighed according to the actual use scenario.

[0036] In this technical solution, when in use, the front baffle 5 and a pair of side baffles 8 are welded to the corresponding positions of the arch-shaped plate 7 to complete the assembly. Then, the mounting end of the arch-shaped plate 7 is installed on the front end of the cargo box, which is the end closest to the cab.

[0037] The beneficial effects of adopting this technical solution are as follows: by designing an arched plate 7, a front baffle 5, and a pair of side plates 3, a structure for a cargo box visor 1 is provided. The arched structure of the arched plate 7 can disperse the impact force generated by material splashing to the entire plate surface, that is, the stress distribution is more uniform when under stress, avoiding local stress concentration, and has higher bending and impact resistance. Compared with a flat plate structure of the same material thickness, it is not easy to deform or break. The design of the arched plate 7, side baffles 8, and front baffle 5 can cover and protect the top and front area of ​​the cab, effectively blocking material splashing, and maintaining reliable protective performance even under extreme working conditions. The reinforcing ribs 6 enhance the structural strength of the arched plate 7, making it less prone to deformation when subjected to impact.

[0038] Overall, compared to traditional flat or simple bending visor 1, this structure effectively disperses impact force, improves overall structural strength, reduces the risk of deformation and cracking, and extends the service life of visor 1. At the same time, the arched overall structure has high rigidity, so the arrangement of traditional reinforcing structures such as reinforcing ribs can be reduced, thereby reducing the overall weight of cargo box visor 1, achieving lightweighting, and avoiding the weight increase problem caused by simply increasing the thickness of materials to improve strength. It has less impact on vehicle fuel consumption and loading capacity. In addition, the arched structure of cargo box visor 1 is a smooth structure with "high in the middle and low on both sides". When the cargo box is loaded and stacked on visor 1, the material on visor 1 will automatically slide down, without generating material accumulation, increasing the safety of visor 1.

[0039] In another technical solution, the side baffle 8 includes an inner reinforcing plate 10, a lower reinforcing plate 9, an outer reinforcing plate 12, and an upper reinforcing plate 11. The inner reinforcing plate 10, the lower reinforcing plate 9, the outer reinforcing plate 12, and the upper reinforcing plate 11 are connected in sequence to form a box-like structure with open ends.

[0040] In the above technical solutions, such as Figure 3 As shown, the side baffle 8 includes an upper reinforcing plate 11 and a lower reinforcing plate 9 arranged vertically, and an inner reinforcing plate 10 and an outer reinforcing plate 12 respectively disposed between the upper reinforcing plate 11 and the lower reinforcing plate 9. The inner reinforcing plate 10 and the outer reinforcing plate 12 are perpendicular to the upper reinforcing plate 11 and the lower reinforcing plate 9. The inner reinforcing plate 10, the lower reinforcing plate 9, the outer reinforcing plate 12 and the upper reinforcing plate 11 are welded together in sequence to form a box-like structure. The box-like structure has open ends, and the two open ends are the two ports of the box-like structure along its length.

[0041] The beneficial effects of adopting this technical solution are that, by setting the inner reinforcing plate 10, the lower reinforcing plate 9, the outer reinforcing plate 12, and the upper reinforcing plate 11, a box-like structure side baffle 8 is provided. The box-like structure side baffle 8 has good rigidity and can withstand greater external forces. When materials impact the side baffle 8, the force will be distributed to the entire side baffle 8 structure through the mutual support and transmission between the reinforcing plates, avoiding local damage and improving its impact resistance under complex working conditions. It effectively prevents the side baffle 8 from deforming or cracking during material impact or vehicle bumps, better protecting the cab. At the same time, the box-like structure can also make the side baffle 8 as lightweight as possible.

[0042] In another technical solution, the reinforcing rib 6 includes a first stiffening plate 13, a second stiffening plate 14, and a third stiffening plate 15. The first stiffening plate 13 and the second stiffening plate 14 are arranged parallel to each other with vertical spacing, and the third stiffening plate 15 is arranged vertically between the first stiffening plate 13 and the second stiffening plate 14 to form an I-shaped reinforcing rib 6.

[0043] In the above technical solutions, such as Figure 4 As shown, the reinforcing rib 6 includes a first rib plate 13, a second rib plate 14, and a third rib plate 15. The first rib plate 13 is arranged along the arc direction of the arch-shaped plate 7 and is connected to the bottom of the arch-shaped plate 7 (e.g., by welding). The second rib plate 14 has the same structure as the first rib plate 13 and is located below the first rib plate 13. The third rib plate 15 is vertically connected between the first rib plate 13 and the second rib plate 14. The first rib plate 13, the second rib plate 14, and the third rib plate 15 form an I-shaped structure.

[0044] The beneficial effects of adopting this technical solution are that the I-shaped reinforcing rib 6 has good compressive and bending resistance, which can enhance the rigidity of the arch-shaped plate 7 when it is subjected to external forces generated by material impact or vehicle bumps, and prevent it from bending and deforming. With the support of the reinforcing rib 6, the force can be distributed more evenly on the arch-shaped plate 7.

[0045] In another technical solution, when the cargo box connected to the cargo box cap 1 is a rectangular cargo box, the radius of curvature of the arch-shaped plate 7 ranges from 12000mm to 18000mm. During the manufacturing of the cargo box cap 1, based on the size of the cargo box and usage requirements, the arch-shaped plate 7 is processed into an arc-shaped structure with a radius of curvature within the range of 12000mm to 18000mm using molds or specialized processing equipment. During actual installation, through measurement and adjustment, the connection position between the cargo box cap 1 and the rectangular cargo box is ensured to be accurate, and the connection method is firm and reliable. The beneficial effect of this technical solution is that this range of radius of curvature is more suitable for rectangular cargo boxes, thereby improving the overall structural strength stability, stress uniformity, and smooth material unloading of the rectangular cargo box. Simultaneously, the manufacturing process is easier to implement.

[0046] In another technical solution, the bottom of the outer reinforcing plate 12 includes a sloping section and a smooth section. The sloping section is close to the front baffle 5. The top end of the outer reinforcing plate 12, away from the front baffle 5, smoothly transitions to the end of the smooth section, away from the front baffle 5. The outer reinforcing plate 12 has the same structure as the inner reinforcing plate 10; specifically, as shown... Figure 3 As shown, the bottom of the outer reinforcing plate 12 is composed of a sloping section and a smooth section connected in sequence. The sloping section is a section close to the front baffle 5, and the smooth section is a section away from the front baffle 5. The sloping section can be arc-shaped or straight, preferably arc-shaped. The high end of the sloping section is the end close to the front baffle 5, which can be regarded as cutting off a piece of the lower part of the outer reinforcing plate 12 close to the front baffle 5.

[0047] The top end of the outer reinforcing plate 12, away from the front baffle 5, is smoothly connected to the smooth section, away from the front baffle 5. The inner reinforcing plate 10 has the same structure as the outer reinforcing plate 12, and the inner reinforcing plate 10 and the outer reinforcing plate 12 are arranged in parallel and spaced apart. The upper reinforcing plate 11 fills the space between the top edges of the inner reinforcing plate 10 and the outer reinforcing plate 12. The shape of the lower reinforcing plate 9 matches the slope section so that when the lower reinforcing plate 9 connects the outer reinforcing plate 12 and the inner reinforcing plate 10, it seals the bottom of the two slope sections.

[0048] The beneficial effects of adopting this technical solution are that by optimizing the structure of the outer reinforcing plate 12, the inner reinforcing plate 10, the upper reinforcing plate 11 and the lower reinforcing plate 9, the force transmission path is further optimized. When subjected to material impact, the arc-shaped structure of the side baffle 8 can more effectively disperse the force and reduce stress concentration. On the other hand, the mass of the side baffle 8 is reduced, making the overall cargo box cap 1 lighter.

[0049] This utility model also provides a cargo box, which includes the aforementioned cargo box brim 1; the cargo box brim 1 has an arched curved main body, combined with an optimized layout of reinforcing ribs 6, achieving a technological breakthrough in significantly reducing weight while ensuring high strength and durability. It has the advantages of simple structure, convenient installation and maintenance, and wide protection range, and can be widely used in mining dump trucks, engineering trucks and other vehicles that require effective protection of the cab, with significant economic and safety benefits.

[0050] In another technical solution, the cargo box further includes a front panel 4, a bottom panel 4, and a pair of side panels 3. The front panel 4 and the bottom panel 4 are both U-shaped. The front panel 4 is perpendicularly disposed at one end of the bottom panel 4 along its length. The pair of side panels 3 are disposed at the two ends of the bottom panel 4 in the same direction. The end of the cargo box brim 1 away from the front baffle 5 is connected to the top of the front panel 4.

[0051] In the above technical solution, the cargo box further includes a front panel 4, a bottom panel 4, and a pair of side panels 3. The front panel 4 and the bottom panel 4 are both U-shaped. The pair of side panels 3 are respectively disposed on both ends of the bottom panel 4 along its arc direction (i.e., on both ends in the same direction). The front panel 4 is perpendicularly disposed on one end of the bottom panel 4 along its length direction. The U-shape of the front panel 4 is adapted to the U-shape of the bottom panel 4 so that the front panel 4 can be perpendicularly disposed on the bottom panel 4 and located between the two upward bending sections of the bottom panel 4. The end of the arched plate 7 of the cargo box brim 1 away from the front baffle 5 is a concave U-shape, which is adapted to the U-shape of the front panel 4.

[0052] In this technical solution, when in use, the bottom of a pair of side plates 3 can be welded to the two tops of the bottom plate 4 in the same direction to extend the two bent sections of the bottom plate 4, so as to facilitate connection with the front plate 4; then the front plate 4 is placed vertically on the bottom plate 4, so that the two bent sections of the front plate 4 are attached to the two bent sections of the bottom plate 4 and the extended bent sections, and then welded to form the main structure of the cargo box; when the cargo box hood 1 is installed with the front plate 4, the pair of side baffles 8 of the cargo box hood 1 are respectively attached to the pair of side plates 3 of the cargo box, and at the same time, the bottom of the U-shaped arched plate 7 is attached to / rested on the top of the front plate 4 so that the cargo box hood 1 is welded to the front plate 4 and the side plates 3 respectively, and finally a whole U-shaped cargo box is formed.

[0053] In actual design or production, the front panel 4 is preferably formed by overlapping three arc plates of the upper, middle and lower parts, with a continuous and smooth U-shaped cross section. Its U-shaped arc transition overlaps with the side panel 3 of the cargo box. Such a front panel 4 structure is an integral arc structure without reinforcing ribs 6, which is lightweight while having high rigidity and strength.

[0054] The beneficial effects of adopting this technical solution are as follows: by designing a U-shaped bottom plate 4, a U-shaped front plate 4, and a pair of side plates 3, a U-shaped cargo box structure is provided. Compared with the existing structure, the front plate 4 eliminates the reinforcing ribs 6, resulting in uniform stress distribution, avoiding stress concentration, and meeting the requirements of lightweight design. The U-shaped structure of the cargo box bottom plate 4 ensures smooth unloading, disperses stress, prevents cracking of the bottom plate 4, and provides good strength and rigidity of the arc-shaped cross-section, allowing for a reduction in the number of reinforcing ribs 6 and achieving the lightweight requirement. Overall, the U-shaped cargo box, compared with the existing cargo box structure, is lighter while maintaining overall structural strength, and also facilitates unloading.

[0055] In another technical solution, the bottom plate 4 is provided with a plurality of horizontal ribs 18 at intervals along its length direction. The horizontal ribs 18 include an upper arc plate 20, a vertical plate 21, and a lower arc plate 22. The upper arc plate 20 and the lower arc plate 22 are both U-shaped.

[0056] The upper arc plate 20 matches the bottom shape of the bottom plate 4 and is connected to the bottom of the bottom plate 4;

[0057] The lower arc plate 22 is located below the upper arc plate 20. The two ends of the lower arc plate 22 are respectively connected to the two ends of the upper arc plate 20, and there is a gap between the middle part of the lower arc plate 22 and the middle part of the upper arc plate 20.

[0058] The vertical plate 21 is vertically arranged between the upper arc plate 20 and the lower arc plate 22 to form a horizontal rib 18 with an I-shaped structure;

[0059] In the above technical solution, the bottom of the base plate 4 is provided with a plurality of horizontal ribs 18, which are spaced apart along the length of the bottom of the base plate 4. Each horizontal rib 18 includes an upper arc plate 20, a vertical plate 21, and a lower arc plate 22. The upper arc plate 20 is arranged along the arc direction of the bottom of the base plate 4, that is, the shape of the upper arc plate 20 is U-shaped and matches the arc of the bottom of the base plate 4. The upper arc plate 20 is connected to the bottom of the base plate 4. The lower arc plate 22 is also U-shaped and is located below the upper arc plate 20. The middle part of the upper arc plate 20 (U-shaped) There is a certain distance between the smooth section and the middle part (U-shaped smooth section) of the lower arc plate 22. The bending section of the lower arc plate 22 shrinks upward and connects with the upper arc plate 20. That is, the two ends of the lower arc plate 22 in the same direction are respectively connected to the two ends of the upper arc plate 20 in the same direction. That is, the lower arc plate 22 smoothly shrinks from the center to both ends along the U-shaped arc transition until both ends are connected with the upper arc plate 20. The vertical plate 21 is vertically arranged between the lower arc plate 22 and the upper arc plate 20 so that the horizontal rib 18 forms an I-shaped structure. The vertical plate 21 plays a central supporting role.

[0060] It should be noted that, in actual design, in order to further improve the strength of the base plate 4, multiple longitudinal beams 19 can also be provided on the base plate 4. The multiple longitudinal beams 19 are spaced apart along the arc direction of the bottom of the base plate 4. The longitudinal beams 19 themselves are arranged along the length direction of the bottom of the base plate 4. Multiple slots are opened on the longitudinal beams 19 along their length direction. The multiple slots correspond one-to-one with multiple transverse ribs 18, so that the transverse ribs 18 can pass through the corresponding slots and be installed at the bottom of the base plate 4. The base plate 4 is provided with a lifting support 17.

[0061] The beneficial effects of adopting this technical solution are that by setting multiple transverse ribs 18 at the bottom of the bottom plate 4, the bottom plate 4 of the U-shaped cargo box forms an equal strength section, which enhances the strength and rigidity of the bottom plate 4 and prevents stress concentration from causing cracks. In addition, the transverse ribs 18 with the I-beam structure are structurally stable and relatively lighter than existing reinforcing ribs.

[0062] In another technical solution, the side panel 3 includes a main board 23, diagonal ribs 24, and a protective plate 25. The main board 23 has a right-angled triangular structure, with its upper part being the hypotenuse. The outer wall of the main board 23 (the outer wall refers to the side wall of the side panel 3 away from the interior of the cargo box during installation; similarly, the inner wall refers to the side wall close to the interior of the cargo box) is provided with reinforcing diagonal ribs 24 and a protective plate 25. The protective plate 25 is located at the lower part of the outer wall of the main board 23 and is arranged along the length of the side panel 3. The protective plate 25 has a channel-shaped structure, and the diagonal ribs 24 are channel steel structures, arranged along the hypotenuse of the main board 23. Overall, by setting the main board 23, diagonal ribs 24, and protective plate 25, a side panel 3 structure with strong structural strength is provided, while effectively protecting the vehicle tires from being hit.

[0063] In another technical solution, the radius of curvature of the arched plate 7 on the cargo box brim 1 is in the range of 10000mm~15000mm. The beneficial effect of adopting this technical solution is that the cargo box brim 1 within this radius of curvature not only meets the function of blocking material splashing, but also is more compatible with the overall structure of the U-shaped cargo box. During vehicle driving and loading and unloading of materials, it can better disperse the impact force and reduce damage to various parts of the cargo box.

[0064] The off-highway dump truck, including the cargo box and the cargo box cap 1, is a technological breakthrough that significantly reduces weight while ensuring high strength and durability. It has the advantages of simple structure, convenient installation and maintenance, and wide protection range. It can be widely used in mining dump trucks, engineering trucks and other vehicles that require effective protection of the cab, and has significant economic and safety benefits.
