[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.

[0021] like Figure 1 and Figure 2 As shown, the rear top crossbeam support plate structure of the cargo box includes a rear top crossbeam outer plate 2 and a rear top crossbeam inner plate 3. The rear top crossbeam outer plate 2 and the rear top crossbeam inner plate 3 are fixedly connected. The rear top crossbeam support plate 1 is fixedly connected to the middle of the rear top crossbeam outer plate 2. A top cover assembly 4 is provided above the rear top crossbeam outer plate 2. The rear top crossbeam support plate 1 is located between the rear top crossbeam outer plate 2 and the top cover assembly 4.

[0022] The rear roof crossbeam support plate 1 connects the inner and outer plates of the rear roof crossbeam with the roof assembly 4 into a whole, and provides Z-direction support for the roof assembly 4. It can transfer the Z-direction force of the cargo box to the entire vehicle body through the rear roof crossbeam support plate 1, thereby dispersing and absorbing impact energy, reducing damage to the vehicle body structure, improving load-bearing capacity, and helping to improve the strength, rigidity and stability of the rear roof crossbeam support plate 1 system.

[0023] like Figure 3 As shown, the bottom end of the roof assembly 4 is fixedly connected to the outer plate 2 of the rear roof crossbeam, and the ends of the outer plate 2 and the inner plate 3 of the rear roof crossbeam form a edging structure 7. The connection between the roof assembly 4 and the outer plate 2 of the rear roof crossbeam allows the impact force to be transmitted from the outer plate 2 to the roof assembly 4, further improving the dispersion effect of impact energy and protecting the vehicle body structure; the outer plate 2 and the inner plate 3 of the rear roof crossbeam are seamlessly connected through the edging structure 7, improving the appearance quality of the vehicle body, while also reducing welding processes and improving production convenience. The edging can also prevent the sharp parts of both from causing injury to operators.

[0024] like Figure 1 As shown, the rear top crossbeam support plate 1 has a Z-shaped cross section. The Z-shaped rear top crossbeam support plate 1 has a large moment of inertia and high stress performance, thus effectively resisting bending and shear forces and improving the strength and stability of the top cover assembly 4.

[0025] like Figure 1 As shown, the rear roof crossbeam support plate 1 has an adhesive surface 8 in the middle, and a vibration damping adhesive 9 is provided on the adhesive surface 8. The vibration damping adhesive 9 connects the rear roof crossbeam support plate 1 and the roof assembly 4. The vibration damping adhesive 9 on the adhesive surface 8 connects the rear roof crossbeam support plate 1 and the roof assembly 4. Since the rear roof crossbeam support plate 1 can transmit the Z-axis force of the cargo box to the entire vehicle body, the vibration damping adhesive 9 can reduce the vehicle body vibration and noise caused by the Z-axis force transmission process. Under bumpy road conditions, it can reduce the instantaneous pressure between the vehicle body structural components and improve the stability of the ride.

[0026] like Figure 1As shown, first reinforcing ribs 11 are evenly distributed on the rear top beam support plate 1, extending from one side to the other. Second reinforcing ribs 12 are provided at the upper end of the rear top beam support plate 1, located between the first reinforcing ribs 11. The first reinforcing ribs 11 are adapted to the U-shaped cross-section of the rear top beam support plate 1, effectively improving the overall structural strength of the rear top beam support plate 1. The second reinforcing ribs 12 further enhance the structural strength of the upper end of the rear top beam support plate 1.

[0027] like Figure 1 As shown, the rear top crossbeam support plate 1 has positioning holes 10 at both ends and welding positioning notches 13 at equal intervals along its edge. The positioning holes 10 are used for initial positioning of the rear top crossbeam support plate 1 during installation, and the welding positioning notches 13 are the welding points of the rear top crossbeam support plate 1, providing an indication for the operator and preventing the rear top crossbeam support plate 1 from being placed incorrectly or in the wrong direction during fixing. The rear top crossbeam support plate 1 is fixed to the outer plate 2 of the rear top crossbeam through multiple welding points, achieving a reliable connection.

[0028] like Figure 1 As shown, weight-reducing holes 14 are evenly distributed on both sides of the rear top crossbeam support plate 1. The weight-reducing holes 14 are located between the first reinforcing ribs 11. The multiple weight-reducing holes 14 reduce the weight of the rear top crossbeam support plate 1, which meets the design requirements for lightweight vehicle body.

[0029] The vehicle includes the aforementioned cargo box rear roof crossbeam support plate structure. During production, the rear roof crossbeam support plate 1, the outer rear roof crossbeam plate 2, and the inner rear roof crossbeam plate 3 are first welded together using 32 double-layer weld points to form the rear roof crossbeam assembly. Then, it is connected to the left side panel assembly 5 and the right side panel assembly 6 via 18 weld points, 10 CO2 welds, and a locking structure. Finally, it is connected to the roof assembly 4 via 12 spot welds and 6 vibration-damping adhesive pads 9. This improves the rigidity of the rear roof crossbeam support plate 1, transmitting the Z-axis force of the cargo box to the entire vehicle body through the rear roof crossbeam support plate 1, and further enhancing the strength of the roof assembly 4. The rear roof crossbeam support plate 1 is interconnected with the side panel assembly and the roof assembly 4, strengthening the structural strength and ensuring connection rigidity, greatly improving the stability of the rear roof crossbeam support plate 1 structure.

[0030] The rear roof crossbeam support plate 1 is developed as a single piece, facilitating assembly. Its rational structural design and simple manufacturing process save on mold costs. The rear roof crossbeam support plate 1 features a symmetrical structure, ensuring good force transmission and uniform impact dispersion, resulting in reliable structural quality. Made of DC04 / 0.7mm thick material, the rear roof crossbeam support plate 1 boasts excellent formability and corrosion resistance, enhancing structural strength, reducing vehicle weight while maintaining rigidity and improving durability.

[0031] The rear top crossbeam support plate structure of this cargo box, by setting the rear top crossbeam support plate 1 on the outer plate 2 of the rear top crossbeam, achieves the effect of transferring the Z-direction force of the vehicle cargo box to the entire vehicle body. It can disperse the impact energy of the rear top crossbeam, protect the vehicle body structure, improve the stability and structural quality of the rear top crossbeam, and meet the load-bearing requirements of the box truck. The rear top crossbeam support plate 1 has a reasonable structural design, is easy to assemble, has reliable performance, simple production process, and low development and application cost.

[0032] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
