Description

Technical Field

[0001] This utility model belongs to the field of dump truck technology, and more specifically, it relates to a dump truck body side panel structure and a dump truck body. Background Technology

[0002] A rectangular dump truck body typically consists of a chassis, a floor, front and rear side panels, and side panels. The floor is mounted on the chassis and supports the cargo. The front side panel is located at the front of the truck body and primarily prevents cargo from sliding forward. The side panels include a left side panel and a right side panel, which are fixed to both sides of the truck body to restrict the lateral movement of cargo within the truck body and prevent cargo from falling from the sides. The rear side panel is located at the rear of the truck body, and its upper left and right ends are hinged to the side panels, allowing it to be opened or closed for easy unloading of cargo.

[0003] Currently, the side panels of existing rectangular dump truck bodies mainly consist of a single flat plate. To improve the structural strength of the flat plate, multiple horizontal beams and multiple vertical beams are set on the flat plate. The multiple horizontal beams and multiple vertical beams are arranged in a cross shape to form a grid structure. Such side panel structures have many components, and the workload in riveting, arranging and welding is large, resulting in low production efficiency. Moreover, the existing dump truck body side panels are mainly made of high-strength steel or higher, which is not suitable for large-area welding. Excessive welding can easily cause the main body of the side panel to crack. Utility Model Content

[0004] The purpose of this utility model is to provide a dump truck body side panel structure and a dump truck body, aiming to solve the problems of complex existing side panel structures, large riveting and welding workload, and low production efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a dump truck body side panel structure is provided, including two side panel units that are fixedly connected vertically. Each side panel unit includes a panel body, and a rectangular frame is fixed to the outer side of the panel body. At least one V-shaped bending section is provided in the middle of the panel body. The V-shaped bending section protrudes to one side of the rectangular frame and is located inside the rectangular frame.

[0006] In one possible implementation, the V-shaped bend is arranged along the width direction of the main body of the plate.

[0007] In one possible implementation, the bending angle of the V-shaped bend is between 120° and 150°.

[0008] In one possible implementation, the rectangular frame includes an upper crossbeam, a lower crossbeam, a front column, and a rear column. The upper crossbeam and the lower crossbeam are respectively fixed to the upper edge and the lower edge of the main body of the plate. The front column and the rear column are respectively fixed to the front edge and the rear edge of the main body of the plate. The front column is connected between the front ends of the upper crossbeam and the lower crossbeam, and the rear column is connected between the rear ends of the upper crossbeam and the lower crossbeam.

[0009] In one possible implementation, a central column is provided in the middle of the rectangular frame. The central column is located between the front column and the rear column. The upper and lower ends of the central column are respectively fixedly connected to the upper crossbeam and the lower crossbeam, and the middle part of the central column is fixedly connected to the main body of the plate.

[0010] In one possible implementation, there are multiple central columns, which are spaced apart and tilted from top to bottom toward the same side.

[0011] In one possible implementation, the front and rear ends of the plate body are respectively provided with reinforcing plates corresponding to the front and rear columns. The reinforcing plates are longitudinally arranged on the inner side of the plate body and cover the V-shaped bend section. A sealing plate is connected between the reinforcing plate and the inner wall of the V-shaped bend section. The sealing plate is used to seal the space formed between the reinforcing plate and the V-shaped bend section.

[0012] In one possible implementation, the rectangular borders in the upper and lower side plate units are symmetrically arranged.

[0013] In one possible implementation, a connecting component is provided between the upper and lower side plate units. The connecting component includes a plug and a slot. The plug is located at the lower end of the upper side plate unit, and the slot is located at the upper end of the lower side plate unit. The plug and the slot are inserted and bolted together for fixation.

[0014] The beneficial effects of the dump truck body side panel structure provided by this utility model are as follows: Compared with the prior art, the dump truck body side panel structure of this utility model, by setting a V-shaped bending section on the main body of the panel and fixing a rectangular frame on the outside of the main body of the panel, so that the V-shaped bending section and the outer rectangular frame form a cooperative support relationship. The rectangular frame acts as an outer rigid frame to restrict the overall displacement of the main body of the panel, while the V-shaped bending section forms an internal support structure in the middle of the main body of the panel through its own protruding shape. Thus, under the premise of reducing the addition of traditional crossbeams and vertical beams, the strength is improved through the optimization of the panel structure itself, which simplifies the overall structure and reduces the number of structural components. Compared with the traditional grid structure, it significantly reduces the amount of riveting and welding work and significantly improves production efficiency.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0028] Please see Figures 1 to 4 This invention provides a side panel structure for a dump truck body. The dump truck body side panel structure includes two side panel units 100 fixedly connected vertically. Each side panel unit 100 includes a main body 1, with a rectangular frame fixed to its outer side. At least one V-shaped bend 11 is provided in the middle of the main body 1, protruding towards one side of the rectangular frame and located inside the rectangular frame. In this embodiment, the dump truck body side panel structure can be applied to the side panel of a dump truck body. The outer side of the main body 1 refers to the outer side of the truck body, and the inner side refers to the inner side of the truck body. In application, the inner side of the main body 1 is used to contact the goods loaded inside the truck body.

[0029] In this embodiment, the V-shaped bend 11 protruding towards one side of the rectangular frame transforms the main body 1 from a planar structure into a three-dimensional supported form, similar to a stable triangular structure in mechanics. When the main body 1 is subjected to external forces such as cargo compression, the two inclined sides of the V-shaped bend 11 can decompose the load perpendicular to the board surface into components along the bending line, which are then transmitted to the entire panel frame through the rectangular frame, preventing the load from concentrating in a certain area of ​​the main body 1 and causing deformation or cracking. Furthermore, the presence of the V-shaped bend 11 increases the local section moment of inertia (i.e., bending resistance) of the main body 1, similar to the effect of forming a "rib" after bending a flat plate, allowing the board to resist external forces with less deformation when subjected to bending moments.

[0030] This utility model provides a dump truck body side panel structure. Compared with the prior art, by setting a V-shaped bending section 11 on the main body 1 and fixing a rectangular frame on the outside of the main body 1, the V-shaped bending section 11 and the outer rectangular frame form a cooperative support relationship. The rectangular frame acts as an outer rigid frame to restrict the overall displacement of the main body 1. The V-shaped bending section 11 forms an inner support structure in the middle of the main body 1 through its own protruding shape. Thus, under the premise of reducing the addition of traditional crossbeams and vertical beams, the strength is improved through the optimization of the plate structure itself, which simplifies the overall structure and reduces the number of structural components. Compared with the traditional grid structure, it significantly reduces the amount of riveting and welding work and significantly improves production efficiency.

[0031] In some embodiments, see Figures 1 to 4 The V-shaped bending section 11 is set along the width direction of the main body 1, so that the bending groove formed by the V-shaped bending section is consistent with the length direction of the truck body. When the dump truck tilts to unload, the slag and other goods are subjected to gravity and can slide quickly and smoothly to the rear of the truck body along the inclined trajectory of the bending groove, which reduces the frictional resistance and contact area between the slag and the inner wall of the main body 1, and avoids residue caused by slag accumulation and jamming on the surface of the side panel.

[0032] In this embodiment, the bending angle of the V-shaped bending section 11 is set between 120° and 150°. This angle range allows the V-shaped structure to effectively decompose external forces through the inclined sides when bearing cargo pressure, while avoiding excessive stress concentration at the bending point due to an excessively small angle, which could cause material fatigue or cracking. Furthermore, in actual processing and production, an angle of 120°-150° facilitates mold design and stamping, reducing the difficulty and cost of the production process, while ensuring a smooth appearance and high dimensional accuracy of the bent panel. In practical use, the bending groove formed by the V-shaped bending section 11 within this angle range ensures that goods such as slag and soil slide smoothly when the truck bed is tilted for unloading, without the groove being too shallow due to an excessively large angle, resulting in insufficient guiding effect.

[0033] In some embodiments, see Figure 1 and Figure 4The rectangular frame includes an upper crossbeam 21, a lower crossbeam 22, a front column 23, and a rear column 24. The upper crossbeam 21 and the lower crossbeam 22 are respectively fixed to the upper and lower edges of the main body 1. The front column 23 and the rear column 24 are respectively fixed to the front and rear edges of the main body 1. The front column 23 is connected between the front ends of the upper crossbeam 21 and the lower crossbeam 22, and the rear column 24 is connected between the rear ends of the upper crossbeam 21 and the lower crossbeam 22. The upper crossbeam 21, the front column 23, the lower crossbeam 22, and the rear column 24 are connected in sequence to form a basic frame, forming a stable external support structure. Based on this, a central column 25 is added in the middle of the rectangular frame. The central column 25 is located between the front column 23 and the rear column 24. The upper and lower ends of the central column 25 are fixedly connected to the upper crossbeam 21 and the lower crossbeam 22, respectively. The middle part of the central column 25 is fixedly connected to the plate body 1, which strengthens the connection between the rectangular frame and the plate body 1, shares the external force borne by the plate body 1, and avoids local stress concentration.

[0034] In this embodiment, there are multiple central pillars 25, which are spaced apart and tilted to the same side from top to bottom. The tilted central pillars 25 change the force transmission path. When the board body 1 is squeezed by the goods, the central pillars 25 can convert part of the external force into a component force along its own tilt direction, guiding the force to be more evenly distributed to the entire frame structure, thereby enhancing the deformation resistance of the board body 1.

[0035] In this embodiment, reinforcing plates 26 are respectively provided at the front end and rear end of the plate body 1, corresponding to the front column 23 and the rear column 24. The reinforcing plates 26 are longitudinally arranged on the inner side of the plate body 1 and cover the V-shaped bending section 11. A sealing plate 27 is connected between the reinforcing plate 26 and the inner wall of the V-shaped bending section 11. The sealing plate 27 is used to seal the space formed between the reinforcing plate 26 and the V-shaped bending section 11.

[0036] In this embodiment, a reinforcing plate 26 is longitudinally arranged on the main body 1, corresponding to the positions of the front post 23 and the rear post 24, and covers the V-shaped bend section 11. This is because the front and rear ends of the panel are easily subjected to significant impact and friction during loading and unloading of goods and vehicle movement, making them structurally weak points. The reinforcing plate 26 effectively disperses and absorbs external forces, enhancing the deformation and impact resistance of the front and rear ends of the main body 1 and preventing localized damage. The sealing plate 27 seals the space formed between the reinforcing plate 26 and the V-shaped bend section 11, preventing goods, dust, and other foreign objects from accumulating in the gap, reducing the risk of corrosion and damage to the panel due to foreign object residue, and facilitating later cleaning and maintenance. In addition, the sealing plate 27, the reinforcing plate 26, and the V-shaped bend section 11 together form a stable combined structure, making the force transmission between the three components smoother and further improving the overall structural strength and stability of the main body 1.

[0037] In this embodiment, the rectangular frames of the upper and lower side panel units 100 in the dump truck body side panel structure are symmetrically arranged. In this way, the inclined central columns 25 in the upper and lower rectangular frames are symmetrical, so that the whole structure presents a neat and harmonious form and enhances the aesthetics.

[0038] In this embodiment, a connecting component 3 is provided between the upper and lower side plate units 100. The connecting component 3 includes a plug 31 and a slot. The plug 31 is disposed on the lower edge of the plate body 1 in the upper side plate unit 100. The plug 31 is located inside the plate body 1. The upper end of the plug 31 is fixed to the plate body 1 by bolting. The lower end of the plug 31 extends downward to the outside of the plate body 1. A structural block 32 is fixed on the upper edge of the plate body 1 of the lower side plate unit 100. The structural block 32 is fixed to the plate body 1 by bolting. The upper edge of the structural block 32 is flush with the upper edge of the plate body 1. The upper end of the structural block 32 is provided with a slot corresponding to the plug 31. During installation, the plug 31 of the upper side plate unit 100 is accurately inserted into the slot of the structural block 32 of the lower side plate unit 100 to achieve quick positioning and initial fixation of the upper and lower side plate units 100. The bolting method is then used to further reinforce the connection and ensure its reliability.

[0039] In this embodiment, there are multiple connecting components 3, which are spaced apart along the length of the plate body 1.

[0040] This utility model also provides a dump truck body. The dump truck body includes the above-mentioned dump truck body side panel structure.

[0041] The present invention provides a dump truck body that, compared with the prior art, uses the above-mentioned dump truck body side panel structure and has all the beneficial effects of the above-mentioned dump truck body side panel structure. It simplifies the overall structure of the body, reduces the number of structural components, and significantly reduces the amount of riveting and welding work compared with the traditional grid structure of the side panel, thus significantly improving production efficiency.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
