[0002] The body structure refers to the layout of the various components that make up the body and the way the components are assembled. According to the way the body bears loads, the body structure can be divided into three types: non-load-bearing, load-bearing and semi-load-bearing. Among the body structural parts, the top cover side support and reinforcement can be achieved through the top cover side longitudinal beams.

[0003] The existing roof side longitudinal beams are usually made by splicing and welding multiple square tubes during processing. However, during the welding process, errors may be caused by manual operation, and there will be certain deformation after welding, which will also cause errors, resulting in problems affecting the accuracy of subsequent assembly.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a high-precision adapted integrated roof side longitudinal beam is provided. Utility Model Content

[0005] The purpose of the utility model is to provide a high-precision adapted integrated roof side longitudinal beam to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-precision adaptive one-piece top cover side longitudinal beam, comprising a tube body and a matching groove, a connecting surface is provided on one side of the tube body, and a shaping surface is provided on the top of the tube body, and the shaping surface is arc-shaped, the matching groove is provided at the lower end of the other side of the tube body, and the matching groove is right-angled, an electrophoretic component is provided on the surface of the tube body, the electrophoretic component comprises an exhaust hole and a drainage hole, an exhaust hole is provided inside the connecting surface, and a drainage hole is provided at the bottom of the tube body.

[0007] Furthermore, the length of the tube body is 9830 mm, the height of the tube body is 131 mm, and the width of the tube body is 123 mm.

[0008] Furthermore, the thickness of the tube body is 2.5 mm, and the material of the tube body is national standard Q355.

[0009] Furthermore, the width of the connecting surface is 55 mm, and the exhaust holes are equidistantly distributed with respect to the connecting surface.

[0010] Furthermore, the diameter of the exhaust holes is 12 mm, and the distance between two adjacent exhaust holes is 1500 mm.

[0011] Furthermore, the bottom width of the tube body is 40 mm, and the drainage holes are equidistantly distributed with respect to the bottom surface of the tube body.

[0012] Furthermore, the diameter of the drainage hole is 12 mm, and the distance between two adjacent drainage holes is 1000 mm.

[0013] Furthermore, one side of the lower portion of the tube body is inclined, and the width of the inclined surface of the tube body is 105 mm.

[0014] The utility model provides a high-precision adapted integrated roof side longitudinal beam, which has the following beneficial effects:

[0015] 1. The utility model sets a matching groove to reserve the assembly position when assembling the glass. Compared with the existing longitudinal beams that require two pipes to be welded together, the total number of welded joints of the longitudinal beam structure of the roof of the present application is reduced, which can reduce the welding deformation, reduce the error caused by manual labor, and improve the accuracy of glass assembly, so that the overall accuracy of the vehicle body roof is improved, the stability is improved, the overall controllability is higher, and the disadvantages of traditional welding are further improved;

[0016] 2. Compared with the existing square tube structure, the utility model adopts a special-shaped tube body, which has a higher fit between the modeling surface and the vehicle body skin, a smoother modeling, and reduces deformation caused by production. At the same time, the integrated square tube is more economical than the traditional type, which reduces production costs, reduces the weight of the vehicle body while ensuring strength, and not only meets the overall flatness, load-bearing and stability of the top cover, but also meets the on-site manual precision requirements, and has a higher fit with the other four pieces.
