[0026] Please refer to Figures 1-6, the present utility model provides a technical solution: a rear enclosure connecting upper crossbeam assembly, including an upper crossbeam assembly main body 1. The upper crossbeam assembly main body 1 is a stamping part, and on the upper crossbeam assembly main body 1, there are provided a driver's seat rear fixing hole 2, a front passenger seat rear fixing hole 3, a seat belt lower fixing hole 4, an upper crossbeam assembly RPS main positioning hole 5, and an upper crossbeam assembly RPS auxiliary positioning hole 6. There are two driver's seat rear fixing holes 2 and two front passenger seat rear fixing holes 3 respectively, and the driver's seat rear fixing holes 2 and the front passenger seat rear fixing holes 3 are respectively located on both sides of the midline of the upper crossbeam assembly main body 1. On the upper surface of the upper crossbeam assembly main body 1, groove structures are respectively stamped at the positions where the driver's seat rear fixing holes 2 and the front passenger seat rear fixing holes 3 are opened. This structure can improve the structural strength of the positions where the driver's seat rear fixing holes 2 and the front passenger seat rear fixing holes 3 are opened, and ensure the stiffness and strength requirements of the local part of the upper crossbeam assembly main body 1. The centers of the driver's seat rear fixing holes 2 and the front passenger seat rear fixing holes 3 are on the same axis, and the driver's seat rear fixing holes 2 and the front passenger seat rear fixing holes 3 are symmetrically arranged about the midline of the upper crossbeam assembly main body 1. This structure enables the upper crossbeam assembly main body 1 to perform rear connection positioning processing for the driver's seat and the front passenger seat respectively through the driver's seat rear fixing holes 2 and the front passenger seat rear fixing holes 3. The seat belt lower fixing hole 4 is opened at a position of the upper crossbeam assembly main body 1 close to the end. This structure enables the upper crossbeam assembly main body 1 to perform installation positioning processing under the seat belts for the driver's position and the front passenger position through the seat belt lower fixing hole 4. And a notch groove 7 is also opened on the upper crossbeam assembly main body 1. On one side of the upper crossbeam assembly main body 1, a seat rear mounting plate 8 and a seat belt mounting plate 9 are respectively fixed. The upper crossbeam assembly RPS main positioning hole 5 and the upper crossbeam assembly RPS auxiliary positioning hole 6 are respectively opened between the driver's seat rear fixing hole 2 and the seat belt lower fixing hole 4, and between the front passenger seat rear fixing hole 3 and the seat belt lower fixing hole 4. The upper crossbeam assembly RPS main positioning hole 5 is a circular hole structure, and the upper crossbeam assembly RPS auxiliary positioning hole 6 is an oblong hole structure. This structure enables the upper crossbeam assembly main body 1 to perform RPS positioning jointly through the upper crossbeam assembly RPS main positioning hole 5 and the upper crossbeam assembly RPS auxiliary positioning hole 6. RPS (Reference Point System) is a commonly used positioning system at present, also known as the positioning point system, which is used in automobile manufacturing. It mainly stipulates the positioning points and their tolerance requirements that the personnel involved in each link from development to manufacturing, inspection to mass vehicle loading should jointly follow, aiming to improve the assembly efficiency, ensure the accuracy of part dimensions, and reduce costs. The RPS system ensures consistent positioning benchmarks throughout the production process, including the development, manufacturing, inspection, and assembly stages, by defining a series of reference points, thereby reducing errors, improving production efficiency, and ensuring product quality.The RPS main positioning holes 5 and the RPS auxiliary positioning holes 6 of the upper crossbeam assembly are both counterbored hole structures. This structure makes the RPS main positioning holes 5 and the RPS auxiliary positioning holes 6 of the upper crossbeam assembly have higher structural strength through the counterbored structure, ensuring the local stiffness and strength of the upper crossbeam assembly body 1 at the positions where the RPS main positioning holes 5 and the RPS auxiliary positioning holes 6 of the upper crossbeam assembly are opened. At both ends of the upper crossbeam assembly body 1, the rear section of the left door sill assembly 10 and the rear section of the right door sill assembly 11 are respectively lapped. And below the upper crossbeam assembly body 1, there is also a rear wall connecting lower crossbeam assembly 12. There are four seat rear mounting plates 8, and the seat rear mounting plates 8 are welded to the back of the upper crossbeam assembly body 1. The lower surface of the upper crossbeam assembly body 1 at the welding positions of the seat rear mounting plates 8 is formed into a convex structure by stamping. This structure makes the seat rear mounting plates 8 fit more closely with the upper crossbeam assembly body 1 through the convex structure, ensuring the welding strength of the seat rear mounting plates 8. The cross-section of the seat rear mounting plates 8 is a U-shaped structure, and the seat rear mounting plates 8 respectively cooperate with the rear fixed holes 2 of the driver's seat and the rear fixed holes 3 of the front passenger seat. This structure makes the seat rear mounting plates 8 have higher strength through the U-shaped structure, ensuring the reliability of the installation of the driver's seat and the front passenger seat. There are two seat belt mounting plates 9, and the seat belt mounting plates 9 are also welded to the back of the upper crossbeam assembly body 1. This structure makes the seat belt mounting plates 9 also reliably connected to the upper crossbeam assembly body 1, ensuring the installation strength of the seat belt. The seat belt mounting plates 9 are also U-shaped parts, and the seat belt mounting plates 9 respectively correspond to the positions of the lower seat belt fixing holes 4. This structure makes the seat belt mounting plates 9 have a stable structure, and the part of the upper crossbeam assembly body 1 where the lower seat belt fixing holes 4 are opened is subjected to local strength enhancement treatment through the seat belt mounting plates 9.,

[0027] Working principle: When using this rear wall connecting upper crossbeam assembly, first, the upper crossbeam assembly body 1 is made by stamping. The notch groove 7 formed in the middle is used for the welding positioning of the handbrake mounting plate. The RPS main positioning holes 5 with circular hole structures and the RPS auxiliary positioning holes 6 with oblong hole structures are respectively made into counterbored structures. The seat rear mounting plates 8 are welded at the positions where the rear fixed holes 2 of the driver's seat and the rear fixed holes 3 of the front passenger seat need to be opened. The seat belt mounting plates 9 are welded at the positions where the lower seat belt fixing holes 4 are opened. Then, the rear fixed holes 2 of the driver's seat and the rear fixed holes 3 of the front passenger seat are respectively opened on the upper crossbeam assembly body 1 and the seat rear mounting plates 8, and the lower seat belt fixing holes 4 are opened on the upper crossbeam assembly body 1 and the seat belt mounting plates 9. Then, the upper crossbeam assembly body 1 is respectively lapped and fixed with the rear section of the left door sill assembly 10, the rear section of the right door sill assembly 11, and the rear wall connecting lower crossbeam assembly 12, thus completing a series of work.
