Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an aluminum alloy sidewall structure of a sidewall type truck. Background Art

[0002] Existing flatbed trucks are mostly made of steel, which results in heavy weight and high energy consumption. Replacing steel with aluminum has become an important lightweight method for flatbed trucks under the new energy trend. Existing aluminum alloy cargo compartment components are mostly integrally welded or riveted structures, which are not conducive to rapid assembly and single component maintenance and replacement. The enclosures and bottom plates are fixed structures and cannot meet the size requirements of different models. In addition, the existing aluminum alloy compartment railings have poor connection strength and overall stability, and safety and reliability are difficult to guarantee during the service life, which is in urgent need of improvement.

[0003] The sideboards are installed on both sides and the rear of the car, and are usually hinged to the floor. When erected, they prevent cargo from sliding out from both sides and are an important part of the car. On the other hand, a firm and stable connection between the sideboards, hinges and floor is also required, which is also a design challenge that must be overcome on the road to lightweighting of sideboard-type trucks. Summary of the invention

[0004] The purpose of the utility model is to provide an aluminum alloy sidewall structure for a sidewall truck, which is obtained by splicing and fixing aluminum profiles, and has the advantages of light weight, strong structure, and convenient assembly and installation; it is easy to assemble and is conducive to the interchangeability of parts, while also improving production efficiency and adapting to mass production.

[0005] To achieve the above object, the technical solution of the present invention is as follows:

[0006] The utility model discloses an aluminum alloy guardrail structure of a guardrail type truck. The guardrail body is manufactured by integrally extruding an aluminum profile with a cavity. End covers are arranged at both ends of the guardrail. A plurality of hinges are evenly distributed at the lower end of the guardrail to connect with the bottom plate of the truck compartment.

[0007] The hollow aluminum profile obtained by extrusion is used as the truck sidewall, which has good rigidity and strength, and greatly reduces the deadweight of the sidewall, meeting the requirements of lightweight. The end cover is made of grooved aluminum profile, the groove width matches the thickness of the aluminum profile, and covers the openings at both ends of the sidewall profile to prevent rainwater, dust and debris from entering the inner cavity of the profile, while also making the sidewall look more beautiful and neat. After the end cover is sealed, it can be fastened to the sidewall profile by anchoring.

[0008] A slot is arranged at a position matching the hinge in the lower part of the inner cavity of the guardrail, into which an insert block can be inserted, and a threaded hole is preset on the insert block, and a threaded fastener passes through one of the base plates of the hinge, the guardrail profile and the insert block for fastening connection.

[0009] As the outer wall of aluminum profiles is usually thin, if the hinge is directly connected to the outer wall of the profile with threaded fasteners, the outer wall of the aluminum profile cannot withstand the shear force of the threaded fasteners, and excessive force can easily cause tearing and damage. Therefore, an insert is added to the inside of the profile to enhance the local strength of the threaded fastening part and provide better protection for the connection.

[0010] The slot has a C-shaped cross section, and the plug block has a step-shaped cross section. The lower width portion of the plug block is inserted into the middle of the slot for fixation.

[0011] The upper edges of both ends of the railing are provided with protrusions, and processing steps are provided at the matching positions of the inner reinforcements of the end caps. The inner reinforcement steps are obtained by machining; the end caps and the edges of the railings are connected by overlapping the protrusions, which can improve the efficiency and accuracy of installation, and the assemblers can save the process of aligning the end caps and can perform riveting on the overlap. Beneficial Effects

[0012] 1. All parts of the utility model are made of extruded aluminum profiles. The multi-cavity extruded profiles of the sidewalls have the advantages of high structural strength and high lightness. Compared with steel truck sidewalls, the weight can be reduced by about 70% without a significant decrease in rigidity and strength, and the energy-saving and emission-reduction effects are obvious.

[0013] 2. The utility model adopts a modular design to form a truck tailgate component, which is easy to assemble and is conducive to the interchangeability of components. It can also improve production efficiency and adapt to mass production.

[0014] 3. The key nodes of the utility model adopt overlapping, plug-in and riveting connection methods, which effectively solves the deformation problem of aluminum alloy components caused by welding and improves the connection strength and stability of the overall structure.

[0015] 4. The utility model adopts a serialized design, and by changing the cross-sectional dimensions of the profile, it can quickly meet the product requirements of different specifications and dimensions of the same structure.

[0016] 5. A plug-in reinforcement structure is added to the hinge connection of the guardrail to ensure better connection strength at the key node hinge connection, thereby increasing the overall life of the guardrail structure with limited cost increase. BRIEF DESCRIPTION OF THE DRAWINGS
