All other embodiments, based on the embodiments of the utility model, which are apparent to those of ordinary skill in the art without inventive faculty, are intended to be within the scope of the utility model. Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, based on the embodiments of the utility model, which are apparent to those of ordinary skill in the art without inventive faculty, are intended to be within the scope of the utility model.
Examples
With reference to fig. 1, the first embodiment of the utility model provides a special-shaped square steel structure side rail of a passenger car roof frame, which comprises a special-shaped square steel side rail main body 3, a roof frame 1 and a side wall frame 11 which are respectively welded on different two ends of the special-shaped square steel side rail main body 3, wherein side window glass 10 is arranged at the front end of the outer side of the side wall frame 11, a side window glass upper spigot 9 is arranged at one end, close to the side wall frame 11, of the special-shaped square steel side rail main body 3, the side window glass upper spigot 9 of the special-shaped square steel side rail main body 3 is directly used as the side window glass upper spigot 9, other rectangular square steel is not required to be welded, or the side edge of the existing rectangular square steel side rail main body is not required to be directly used as the side window glass upper spigot 9 through side top skin rolling and edge folding, and the side edge folding is required to be welded, and the problems of high welding workload, difficult control and poor light weight effect exist.
Further, the special-shaped square steel side longitudinal beam main body 3 is provided with a middle top cover lap joint sinking table 4 at one end close to the top cover framework 1 for directly tower-connecting the middle top cover 2 at the top of the top cover framework 1, so that the structure can be simplified, the light weight can be realized, and the sinking structure ensures the flatness and the attractiveness of the whole top cover framework 1 after the middle top cover 2 is lapped. The problem that the top of an existing rectangular square steel side longitudinal beam cannot be directly overlapped with a middle top skin 2, and a framework is required to be independently arranged at a position slightly far from the side longitudinal beam for overlapping the middle top skin 2 and a side top skin is solved.
Further, the outside top of dysmorphism square steel limit longeron main part 3 is equipped with dysmorphism square steel limit longeron R angle cambered surface 5 (see fig. 1) for direct welding topside external decoration fixed bolster 6 has reduced reverse-penetrating bolt and connecting plate, has improved current rectangle square steel limit longeron, when installing topside external decoration 7, needs to weld reverse-penetrating bolt and connecting plate on top cap skeleton 1, is connected topside external decoration fixed bolster 6 and top cap skeleton 1 through the bolt, and bolt department needs to beat gluey sealedly, increases the work load and has the problem of bolt hole hidden danger that leaks.
