Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle body welding manufacturing, specifically to a welded assembly of the floor plate of a small truck body. Background Technology
[0002] The truck bed floor welded assembly is the core structural component of the truck bed. It consists of a floor plate, longitudinal beams, transverse beams, reinforcing ribs, and connectors, which are connected into a whole through welding and other processes. It has the characteristics of strong load-bearing capacity, high structural strength, strong deformation resistance, and good corrosion resistance.
[0003] During the welding process of the truck floor assembly, it is usually necessary to precisely weld the support plate to the underlying frame. However, traditional welding structures often suffer from insufficient stability. After prolonged use, the truck floor is prone to weld breakage and warping of the support plate, which not only affects the ease of use of the truck floor but also greatly shortens its service life. Therefore, it is urgent to improve and optimize the traditional welding structure to enhance the stability and durability of the truck floor. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a welded assembly of the floor panel for a small truck, so as to solve the technical problems of weld breakage and support plate warping during long-term use of the floor panel.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a welded assembly of a cargo box floor for a small truck, comprising several support plates, a support frame installed below the support plates, and the support frame comprising two sets of side frames, with several support beams and I-beams welded between the two sets of side frames, and two sets of support longitudinal beams welded below the support beams and I-beams, and mounting pieces fixedly welded to the bottom surface of the support plates, the mounting pieces being opposite to the support beams and fitting against one side of the support beams, and several welding grooves being formed on the mounting pieces.
[0006] By adopting the above technical solution, several support plates serve as the load-bearing surfaces of the carriage floor, ensuring that the cargo can be stably and evenly distributed on the carriage floor. At the same time, a support frame consisting of a frame, support beams, I-beams, and support longitudinal beams is installed below the support plates. This frame structure is reasonably designed and can effectively distribute and bear the weight of the cargo, thereby improving the load-bearing capacity of the carriage floor.
[0007] Furthermore, the welding groove has a long rectangular structure and serves as the welding point between the mounting plate and the supporting beam.
[0008] By adopting the above technical solution for the welding points of the mounting plate and the supporting beam, this design makes the welding process more precise and controllable, avoids deviations and misalignments during the welding process, and improves the welding quality.
[0009] Furthermore, the support plate and the mounting piece are vertically welded together, and the outer periphery of the support plate is welded and fixed to the frame and the I-beam.
[0010] By adopting the above technical solution, the support plate can more stably bear the weight of the goods, avoiding the goods from slipping or being damaged due to tilting or skewing.
[0011] Furthermore, the supporting longitudinal beams, supporting transverse beams, and I-beams are vertically welded together, and supporting angle steel is welded to the intersection of the supporting longitudinal beams and supporting transverse beams.
[0012] By adopting the above technical solutions, the support frame has high rigidity and stability in both the longitudinal and transverse directions, and can effectively resist the impact and vibration of goods during transportation.
[0013] Furthermore, several first support ribs are welded to both sides of the I-beam, and several second support ribs are welded to the inner sides of the support beam and the support longitudinal beam.
[0014] By adopting the above technical solution, the first support rib makes the I-beam more stable when subjected to lateral forces, avoiding bending or deformation caused by lateral forces.
[0015] Furthermore, several of the first and second support ribs are arranged linearly at equal intervals in a figure-eight pattern.
[0016] By adopting the above technical solution, the supporting ribs can distribute stress more evenly when subjected to pressure, avoiding local damage caused by stress concentration. At the same time, the figure-eight arrangement can also enhance the shear resistance of the supporting ribs and improve the stability of the overall structure.
[0017] Furthermore, several of the aforementioned supporting beams and I-beams are arranged in an alternating pattern and are evenly spaced.
[0018] By adopting the above technical solutions, the support points of the car floor assembly are made more uniform and distributed, improving its load-bearing capacity and stability. At the same time, the staggered arrangement can also enhance the torsional resistance of the car floor, avoiding structural damage caused by torsion.
[0019] In summary, the present invention has the following main advantages:
[0020] 1. This utility model uses mounting plates and welding grooves. The mounting plates, which are fixedly welded to the bottom surface of the support plate, are tightly fitted to the support beam. Welding is then performed using welding grooves, which enhances the precision and controllability of the welding process. The welding grooves serve as predetermined welding points, ensuring accurate positioning of the mounting plates and support beams during the welding process and avoiding welding deviations. At the same time, compared with the traditional direct welding structure, this welding method increases the welding area, making the weld more robust and stable. The welding grooves allow for better formation of the molten pool, resulting in higher weld quality and further enhancing the welded structural strength of the support plate. This enhanced welded structural strength effectively resists the weight of goods and the impact during transportation, extending the service life of the vehicle floor assembly.
[0021] 2. This utility model provides additional support points for the car floor by welding first and second support ribs to both sides of the I-beam and the inner sides of the support beam and support longitudinal beam. The presence of these support ribs allows the car floor to distribute the pressure more evenly to each support component when bearing the weight of the cargo. At the same time, the first and second support ribs are arranged in a figure-eight equidistant linear arrangement, which effectively optimizes the stress distribution and avoids local damage caused by stress concentration.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0029] Example 1:
[0030] A type of welded assembly for the floor of a small truck, such as Figure 1-5 As shown, the system includes several support plates 6, with a support frame installed below each support plate 6. The support frame includes two sets of side frames 1, with several support beams 2 and I-beams 3 welded between the two sets of side frames 1. Below the support beams 2 and I-beams 3, two sets of support longitudinal beams 4 are welded. Mounting pieces 8 are fixedly welded to the bottom surface of the support plates 6. The mounting pieces 8 are positioned opposite to the support beams 2 and are attached to one side of the support beams 2. Several welding grooves 9 are formed on the mounting pieces 8. The support plates 6 serve as the load-bearing surface of the carriage floor, ensuring the safety of the cargo. It can be stably and evenly distributed on the car body floor. At the same time, a support frame consisting of a frame 1, a support beam 2, an I-beam beam 3 and a support longitudinal beam 4 is installed below the support plate 6. The frame structure is reasonably designed and can effectively distribute and bear the weight of the cargo, improving the load-bearing capacity of the car body floor. In addition, the mounting piece 8 fixedly welded to the bottom surface of the support plate 6 is closely fitted to the support beam 2 and welded through the welding groove 9. This not only simplifies the welding process, but also improves the firmness and stability of the welding, ensuring the overall structural strength of the car body floor assembly.
[0031] See Figure 4 , Figure 5 The welding groove 9 has a long rectangular structure and serves as the welding point between the mounting plate 8 and the supporting beam 2. This design makes the welding process more precise and controllable, avoiding deviations and misalignments during the welding process and improving the welding quality. At the same time, the long rectangular welding groove 9 can increase the welding area, making the connection between the mounting plate 8 and the supporting beam 2 more solid and stable, and enhancing the impact and vibration resistance of the carriage floor assembly.
[0032] See Figure 1 , Figure 2 , Figure 5 The support plate 6 and the mounting plate 8 are vertically welded together. The outer periphery of the support plate 6 is welded and fixed to the frame 1 and the I-beam 3, which enables the support plate 6 to more stably bear the weight of the goods and avoid the goods from slipping or being damaged due to tilting or skewing. At the same time, the outer periphery of the support plate 6 is welded and fixed to the frame 1 and the I-beam 3. This all-round welding method makes the car body floor assembly more integrated and stable, and improves its bending and torsional resistance.
[0033] See Figure 2 , Figure 4The supporting longitudinal beam 4 is vertically welded to the supporting transverse beam 2 and the I-beam 3. Supporting angle steel 5 is welded at the intersection of the supporting longitudinal beam 4 and the supporting transverse beam 2, which gives the supporting frame high rigidity and stability in both longitudinal and transverse directions, and can effectively resist the impact and vibration of goods during transportation. At the same time, the supporting angle steel 5 welded at the intersection of the supporting longitudinal beam 4 and the supporting transverse beam 2 not only enhances the load-bearing capacity of the intersection, but also improves the shear and compression resistance of the overall structure.
[0034] Example 2:
[0035] See Figure 2 , Figure 3 , Figure 4 Several first support ribs 701 are welded to both sides of the I-beam 3, and several second support ribs 702 are welded to the inner sides of the support beams 2 and 4. The first support ribs 701 make the I-beam 3 more stable when subjected to lateral forces, avoiding bending or deformation caused by lateral forces. At the same time, the second support ribs 702 welded to the inner sides of the support beams 2 and 4 enhance the bending resistance of the support beams 2 and 4 and improve the stability of the overall structure.
[0036] See Figure 2 , Figure 3 , Figure 4 The first support ribs 701 and the second support ribs 702 are arranged in a figure-eight pattern with equal spacing, which allows the support ribs to distribute stress more evenly when under pressure, avoiding local damage caused by stress concentration. At the same time, the figure-eight arrangement can also enhance the shear resistance of the support ribs and improve the stability of the overall structure. In addition, the equidistant linear arrangement makes the weight distribution of the vehicle floor assembly more uniform, which is beneficial to the vehicle's driving stability and fuel economy. At the same time, this arrangement is also conducive to the manufacturing and processing of the vehicle floor, improving production efficiency and product quality.
[0037] See Figure 1 , Figure 2 , Figure 4 Several supporting crossbeams 2 and I-beams 3 are arranged in an alternating and equidistant manner, making the support points of the vehicle floor assembly more even and distributed, thus improving its load-bearing capacity and stability. At the same time, the alternating arrangement can also enhance the torsional resistance of the vehicle floor, avoiding structural damage caused by torsion. In addition, the equidistant and uniform arrangement makes the weight and stiffness distribution of the vehicle floor assembly more reasonable, which is beneficial to the vehicle's driving stability and handling.
[0038] The implementation principle of this embodiment is as follows: several support plates 6 serve as the load-bearing surface of the carriage floor, and a support frame consisting of a frame 1, support beams 2, I-beams 3, and support longitudinal beams 4 is installed below them to form a stable structural foundation. The support plates 6 are tightly fitted to the support beams 2 by mounting pieces 8 fixedly welded to the bottom surface, and are welded using welding grooves 9 to ensure the strength and stability of the weld. Compared with the traditional direct welding structure, this further improves the welded structural strength of the support plates 6 and extends the service life of the carriage floor assembly. At the same time, the outer periphery of the support plates 6 and the frame 1... The support beam 4 is welded and fixed to the support beam 2 and the support beam 3 to further enhance the overall strength of the carriage floor. The support longitudinal beam 4 is welded perpendicularly to the support beam 2 and the support beam 3, and support angle steel 5 is set at the intersection of the welds to improve the load-bearing capacity. In addition, the first support rib plate 701 and the second support rib plate 702 are welded to the two sides of the support beam 3 and the inner sides of the support beam 2 and the support longitudinal beam 4, respectively, and are arranged in a figure-eight equidistant linear arrangement to optimize stress distribution, further improve the stability and load-bearing capacity of the carriage floor, reduce the probability of partial dents in the carriage floor during use, and improve its structural strength and service life.
