Abstract

The invention belongs to the technical field of automobile parts, and particularly relates to an automobile rear longitudinal beam structure, an automobile rear longitudinal beam assembly and an automobile. The automobile rear longitudinal beam structure comprises a rear longitudinal beam body, the front end of the rear longitudinal beam body is bent to form a bent connecting plate used for being connected with an automobile doorsill, and the bent connecting plate comprises a first side plate, a second side plate and a third side plate; wherein the first side plate and the third side plate are located on the two opposite sides of the second side plate; and one end of the second side plate is connected with the first side plate at a first preset angle, and the other end of the second side plate is connected with the third side plate at a second preset angle. According to the rear longitudinal beam structure, the bent connecting plate is tightly connected with the three faces of the automobile threshold, and it is guaranteed that the rear end of the automobile threshold has excellent performance and good rear collision performance; besides, connection between the automobile rear longitudinal beam and the automobile threshold can be realized without additional connecting pieces, so that the weight of the automobile rear longitudinal beam structure is reduced, and the lightweight design of the automobile is facilitated.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to an automobile rear longitudinal beam structure, an assembly and an automobile. Background technique [0002] As one of the key parts of the car body, the rear longitudinal beam assembly of the car plays a load-bearing role and absorbs collision impact in the car structure. In the prior art, the automobile rear longitudinal beam assembly is usually made of tailor-welded steel parts, and the automobile rear longitudinal beam assembly is generally composed of multiple steel stamping parts, with a large number of parts and a complicated structure, and the automobile rear longitudinal beam assembly The resulting welding accuracy is not high; in addition, when the steel automobile rear longitudinal beam assembly is connected with other structural parts of the automobile, it is often necessary to add accessories to the connection to increase the rigidity of the connection to meet the...
