[0002] like Figure 4 As shown, in the existing roof assembly, the rear portion of the metal roof cover 200 is usually fixedly connected to the rear cross beam 100 of the roof cover by spot welding. This roof assembly faces the following technical problems:

[0025] The following will describe the implementation of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0026] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0027] like Figures 1 to 3 A roof assembly is shown, the roof assembly includes a rear cross beam of a roof cover and a roof component, the rear cross beam of the roof cover includes a cross beam lower plate 1 and a cross beam upper plate 2 connected to the upper side of the cross beam lower plate 1, the cross beam lower plate 1 and the cross beam upper plate 2 form a cavity structure; the roof component is a metal roof cover 3 welded to the upper side of the cross beam upper plate 2 at the rear, or the roof component is a skylight 4 glued to the upper side of the cross beam upper plate 2 at the rear; the cross beam lower plate 1 is provided with a welding through hole 106, the welding through hole 106 is used to provide a welding channel for welding between the metal roof cover 3 and the cross beam upper plate 2.

[0028] By adopting the above technical solution, the upper crossbeam plate 2 and the lower crossbeam plate 1 are connected to form a rear crossbeam of the roof with a cavity structure, which can improve the strength and rigidity of the rear crossbeam of the roof, thereby strengthening the supporting capacity of the rear crossbeam of the roof for the roof components. In particular, when the roof component is a heavier glass skylight, the rear crossbeam of the roof with a stronger supporting capacity can provide a stable support for the glass skylight. In the above technical solution, a welding hole 106 is provided on the lower crossbeam plate 1, and the welding hole 106 allows the welding gun to extend into the cavity structure for welding, providing a welding channel for welding between the metal roof 3 and the upper crossbeam plate 2, so that the lower crossbeam plate 1 can be applied to both the vehicle model using the skylight 4 and the vehicle model using the metal roof 3, thereby reducing the types of parts of the roof assembly, providing convenience for the expansion of vehicle model configuration, and also helping to reduce costs. In addition, when expanding between the vehicle model configuration using the skylight 4 and the vehicle model configuration using the metal roof 3, the structure of the upper crossbeam plate 2 only needs to be fine-tuned, which also provides convenience for the expansion of vehicle model configuration. The above technical solution improves the expandability of the roof assembly. The roof assembly is a flexible structure that can be expanded between the vehicle configuration using the skylight 4 and the vehicle configuration using the metal roof cover 3.

[0029] In some embodiments, Figure 2 As shown, a plurality of welding holes 106 are provided on the lower plate 1 of the cross beam, and the plurality of welding holes 106 are arranged in sequence and spaced in the transverse direction.

As a preferred example, the welding holes 106 are flanged holes, and the welding holes 106 are provided as flanged holes to help ensure the structural stability of the lower plate 1 of the cross beam and the cross beam behind the top cover. In a specific implementation, the welding holes 106 are usually provided below the welding portion between the metal top cover 3 and the upper plate 2 of the cross beam.

With the above technical solution, the U-shaped cross beam lower plate 1 can form a transverse cavity structure with the cross beam upper plate 2 which is flat as a whole, which helps to reduce the requirements for the structure of the cross beam upper plate 2. Specifically, the cross beam lower plate 1 includes a bottom plate 101, a first side plate 102 folded upward from the front edge of the bottom plate 101, a first flange 104 folded forward from the upper edge of the first side plate 102, a second side plate 103 folded upward from the rear edge of the bottom plate 101, and a second flange 105 folded backward from the upper edge of the second side plate 103, and a welding hole 106 is provided on the bottom plate 101.
