Abstract
Description
Technical Field
[0001] The embodiments of this utility model relate to the technical field of truck body panels, specifically, to an assembled truck body side panel. Background Technology
[0002] Traditionally, truck body connecting plates are welded together to form the overall structure of the truck body. The welding process involves high-temperature melting of metal, which generates a large amount of welding fumes. These fumes contain harmful gases such as nitrogen oxides, carbon monoxide, and hydrogen fluoride. Furthermore, in the post-weld painting process, paint is used to cover welding marks and improve the appearance and corrosion resistance of the truck body. Benzene compounds and formaldehyde in the paint volatilize during spraying and drying, not only harming the health of workers but also causing air pollution and exacerbating the environmental burden.
[0003] In terms of labor costs, welding is a skilled trade that requires a high level of technical proficiency and experience from operators. This increases production costs, and during later maintenance, if the welded truck body connecting plates are damaged, repairs will consume a significant amount of time and effort, affecting the normal operation and turnover of the trucks. Utility Model Content
[0004] To overcome the above-mentioned defects, this utility model provides an assembled side panel for the truck body, which solves the technical problems of high production cost, serious environmental pollution and high maintenance cost of the truck body using welding process in the prior art.
[0005] According to one aspect, at least one embodiment of the present invention provides an assembled vehicle side panel, comprising: at least two unit panels, each unit panel having a connecting portion, the two unit panels being connected by the connecting portion to form a side panel body, the connecting portion comprising a first segment and a second segment, one end of the second segment being connected to the first segment, and the other end extending toward one side of the first segment;
[0006] The second segment is provided with a first connecting hole for fasteners to pass through, and two adjacent first connecting holes allow fasteners to pass through so that the two unit plates can be connected to each other.
[0007] For example, in an assembled carriage side panel provided by at least one embodiment of the present invention, the second section has a first extension section, one end of the first extension section is connected to the first section, and the other end extends in a direction inclined to the first section to form a first groove. The first groove is configured such that after the two connecting parts are joined together, the two corresponding first grooves together constitute a processing groove for applying glue.
[0008] For example, in an assembled carriage side panel provided in at least one embodiment of the present invention, the second section further has a second extension section connected to the first extension section, the second extension section extending normally relative to the first section, and the second extension section is provided with the first connection hole.
[0009] For example, in at least one embodiment of the present invention, the extension path of the first extension section is straight.
[0010] For example, in an assembled carriage side panel provided by at least one embodiment of the present invention, the cross-sectional shape of the first extension section along the length direction is arc-shaped, and two first extension sections can form a processing groove after being joined together, wherein the cross-sectional shape of the processing groove along the length direction is semi-circular.
[0011] For example, in at least one embodiment of the present invention, an assembled carriage side panel further includes: a fastening member for covering two adjacent connecting portions, the fastening member having a second connecting hole for fasteners to pass through and connect with the connecting portions.
[0012] For example, in an assembled carriage side panel provided in at least one embodiment of the present invention, the fastening member is configured such that after it fastens and blocks two adjacent connecting portions, the first connecting hole and the second connecting hole can allow fasteners to pass through.
[0013] For example, in at least one embodiment of the present invention, an assembled carriage side panel is provided, wherein the connecting part further has a third section with one end connected to the second extension section, parallel to the first section, and the outer end face of the third section is used to abut against the inner end face of the fastening member.
[0014] For example, in at least one embodiment of the present invention, an assembled carriage side panel is provided, wherein the third section is provided with a third connecting hole, and the fastener is configured such that after it fastens and blocks two adjacent connecting parts, the second connecting hole and the third connecting hole can be passed through.
[0015] For example, in an assembled carriage side panel provided by at least one embodiment of the present invention, the unit panel has a protrusion connected to the connecting portion, the protrusion and the third segment are located on the same side of the first segment, and the fastening member is configured such that after it fastens and covers two adjacent connecting portions, the outer end face of the fastening member is flush with the end face of the protrusion away from the first segment.
[0016] The beneficial effects of the embodiments of this utility model are as follows:
[0017] Compared to traditional welding and painting processes, this invention provides a mechanically connected (e.g., bolted) assembly method while retaining the welding process. When using welding, the first connecting hole can be omitted or sealed with adhesive. Alternatively, welding can be eliminated, improving the production environment, reducing health hazards to operators, and decreasing emissions, aligning with green and environmentally friendly production principles. Since specialized welding workers are not required, companies do not need to spend significant costs recruiting and training skilled welders. Ordinary workers can assemble the unit panels with simple training, reducing labor costs. When the side panel is damaged, the damaged unit panel can be easily removed for replacement or repair simply by removing the corresponding fasteners. Unlike traditional welded structures, there is no need for complex repair operations on large areas, significantly reducing repair difficulty and time, minimizing truck downtime due to repairs, improving truck utilization efficiency, and lowering maintenance costs.
[0018] Meanwhile, the combination of multiple unit panels via connecting parts makes the assembly of the carriage side panels more flexible. The number and combination of unit panels can be adjusted according to actual transportation needs, changing the size and shape of the main body of the side panel. Furthermore, the standardized connecting parts and the design of the first connecting hole enhance the versatility of the unit panels, facilitating standardized production and inventory management, and reducing production management costs.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.
[0028] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0033] like Figure 1 As shown, this invention provides an assembled side panel for a truck body. The connecting portion 101 of each unit panel 1 consists of a first section 102 and a second section 103. The first section 102 serves as the connection base, providing initial positioning and support. One end of the second section 103 is connected to the first section 102, and the other end extends towards one side of the first section 102 to provide a fastening connection position. When assembling the side panel body 2, the second section 103 of the connecting portion 101 of two adjacent unit panels 1 is designed to allow fasteners to pass through, and the first connecting hole 104 on the second section 103 is also designed to allow fasteners to pass through. By passing fasteners 4 (such as bolts, rivets, pins, etc.) through the corresponding first connecting hole 104, the two unit panels 1 are connected together to form a stable side panel body 2 structure, thus realizing the assembly of the truck body side panel.
[0034] Compared to traditional welding and painting processes, this solution provides a mechanically connected (such as bolted) assembly method while retaining the welding process. When using welding, the first connecting hole 104 can be left unprocessed or sealed with adhesive.
[0035] Welding can also be eliminated, improving the production environment, reducing health risks to operators, and decreasing emissions, aligning with green and environmentally friendly production principles. Since specialized welders are not required, companies avoid the high costs of recruiting and training skilled welders; ordinary workers can assemble unit panel 1 with simple training, reducing labor costs. When the side panel body 2 is damaged, the damaged unit panel 1 can be easily removed for replacement or repair simply by removing the corresponding fasteners 4. Unlike traditional welded structures, there is no need for complex repairs over large areas, significantly reducing maintenance difficulty and time, minimizing truck downtime due to repairs, improving truck utilization efficiency, and lowering maintenance costs.
[0036] Meanwhile, the combination of multiple unit panels 1 via connecting parts 101 makes the assembly of the carriage side panels more flexible. The number and combination method of unit panels 1 can be adjusted according to actual transportation needs, changing the size and shape of the side panel body 2. Furthermore, the standardized design of the connecting parts 101 and the first connecting hole 104 enhances the versatility of the unit panels 1, facilitating standardized production and inventory management, and reducing production management costs.
[0037] like Figure 2 As shown, in some examples, one end of the first extension 1031 of the second segment 103 is connected to the first segment 102, and the other end extends in a direction inclined to the first segment 102, thereby forming a clearance portion. When the connecting portions 101 of the two unit plates 1 are joined, they together form a complete processing groove 105. This processing groove 105 provides a space carrier for the subsequent glue application process, ensuring that the glue can be filled evenly. On the one hand, it can effectively prevent dust, moisture and other external substances from entering the interior of the carriage, achieving dustproof and waterproof functions. For example, when driving in rainy weather or passing through dusty road sections, the goods inside the carriage can be protected from the influence of the external environment; on the other hand, the adhesive effect of the glue increases the overall strength of the connecting portion 101, and at the same time, the filled processing groove 105 makes the surface of the connection smoother, improving the aesthetics of the carriage.
[0038] like Figure 2 As shown, in some examples, one end of the second extension 1032 is connected to one end of the first extension 1031, and the other end extends normally relative to the first segment 102, so that the two second extensions 1032 can be planarly fitted during the assembly of the unit panel 1, which increases the contact area between the unit panel 1, and can better resist the vibration and deformation of the carriage during the driving process, ensuring the stability of the carriage structure in long-term use.
[0039] like Figures 3-6As shown, in some examples, in the truck body connecting plate structure, the first extension segment 1031 has a straight or arc-shaped cross-section along its length. The first extension segment 1031 with a straight cross-section is similar to a chamfer design. After two first extension segments 1031 are joined together, a processing groove 105 can be formed. The groove wall formed by the first extension segment 1031 with a straight cross-section can enable the glue to form a flat and regular sealing layer when it is cured, ensuring the consistency of the sealing effect and effectively preventing external dust and moisture from entering the interior of the truck body.
[0040] The first extension 1031 of the processing groove 105 has a semi-circular cross-sectional shape along its length. Utilizing an arc-shaped spatial structure, it increases the contact area between the adhesive and the groove wall of the processing groove 105. This allows for better adhesive retention, making it particularly suitable for applications with high sealing requirements. When facing changes in external pressure or vibrations in the vehicle compartment, the arc-shaped structure can better disperse stress, preventing cracking or detachment of the sealing layer, further improving sealing performance and the structural strength of the connection part 101.
[0041] like Figures 3-6 As shown, in some examples, the fastener 3 is used to cover two adjacent connecting parts 101, and the fastener 3 is stably connected to the connecting parts 101 by the fastener 4.
[0042] like Figure 1 As shown, in some examples, the second connecting hole 301 on the fastener 3 corresponds to the first connecting hole 104 on the second extension 1032 of the connecting portion 101. During assembly, after the two unit plates 1 are initially joined through the connecting portion 101, the fastener 3 is placed over the connecting portion 101, allowing fasteners to pass through the second connecting hole 301 and the first connecting hole 104. Fasteners 4 (such as bolts or pins) are then inserted again, securing the two connecting portions 101 while simultaneously fixing the fastener 3 firmly to the connecting portion 101. This not only enhances the connection strength between the unit plates 1 but also provides stable shielding of the connecting portion 101 by the fastener 3.
[0043] like Figure 3 and Figure 5 As shown, in some examples, one end of the third segment 107 of the connecting part 101 is connected to the second extension segment 1032, and its outer end face is used to abut against the inner end face of the fastener 3. The third segment 107 is parallel to the first segment 102, which can make the contact with the fastener 3 tighter and improve the connection stability between the fastener 3 and the connecting part 101.
[0044] like Figure 1As shown, in some examples, the addition of the third connecting hole 1071 on the third segment 107, in conjunction with the second connecting hole 301 of the fastener 3 and the first connecting hole 104 of the connecting part 101, creates a more stable connection. During the assembly of the side panel, the two adjacent connecting parts 101 first cooperate with the fastener 4 through the first connecting hole 104 to achieve a fixed connection in the splicing direction of the unit panel 1, thus initially constructing the frame of the side panel body 2. Subsequently, the fastener 3 covers the outside of the two adjacent connecting parts 101. At this time, the second connecting hole 301 of the fastener 3 and the third connecting hole 1071 on the third segment 107 can allow the fastener to pass through. By inserting the fastener 4 (such as bolts, rivets, etc.), the fixed connection between the fastener 3 and the connecting part 101 is completed in the direction perpendicular to the splicing direction of the unit panel 1. This forms a mutually perpendicular constraint relationship, making the entire connection structure more stable.
[0045] like Figure 1 and Figure 2 As shown, in some examples, the protrusion 108 of unit plate 1 is connected to the connecting portion 101 and is located on the same side of the first segment 102 as the third segment 107. When the fastening member 3 fastens and covers two adjacent connecting portions 101, the outer end face of the fastening member 3 can be flush with the end face of the protrusion 108 away from the first segment 102. This makes the outer surface of the carriage side panel present a continuous and flat visual effect, reducing the difficulty of cleaning and maintenance.
[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
