Problems solved by technology

[0003] At present, on the basis of the configuration of the traditional sheet metal roof (including no sunroof, small sunroof and panoramic sunroof configuration), the configuration of the canopy roof is added, but the car body structures used for the sheet metal roof and the canopy roof are different. The existing body structure It is difficult to install the configuration of the roof of the sky. In order to configure the roof of the sky, it is often necessary to change the side wall structure, D-pillar structure, front and rear beam structure, and roof structure of the car, resulting in an increase in design costs and production costs; and equipped with the roof of the sky The body structure is difficult to realize the generalization of the interior and electrical appliances, which causes great inconvenience to the design and production

Embodiment 1

[0079] like Figure 1 to Figure 11 As shown, the present invention provides a rear beam structure, comprising:

[0080] The first rear cross member upper plate 3 and the second rear cross member upper plate 9;

[0081] The rear cross beam lower plate 4, the rear cross beam lower plate 4 is connected with the first rear cross beam upper plate 3 or the second rear cross beam upper plate 9;

[0082] The rear cross member outer plate 10 is connected with the second rear cross member upper plate 9;

[0083] The first rear cross beam upper plate 3 and the rear cross beam lower plate 4 form the first rear cross beam structure, and the first rear cross beam structure is used for the sheet metal roof vehicle;

[0084] The second rear cross beam upper plate 9, the rear cross beam lower plate 4 and the rear cross beam outer plate 10 form the second rear cross beam structure, and the second rear cross beam structure is used for the canopy roof vehicle.

[0085] Optionally, it also incl...

Embodiment 2

[0110] like Figure 12 to Figure 18 As shown, based on the rear cross member structure, the body frame assembly and the vehicle in the first embodiment, the difference between this embodiment and the first embodiment is that the vehicle in this embodiment is a canopy car, which adopts the second rear cross member structure. ; see Figure 12 , the canopy top cover assembly is only composed of a single piece of the rear beam outer plate 10, the second rear beam structure includes the second rear beam upper plate 9, the rear beam lower plate 4 and the left and right hinge reinforcement plates 5. The welding level is composed of a single piece. Consistent with the welding level of the sheet metal top in the first embodiment, that is, the D-pillar upper reinforcing plate 8 and the D-pillar upper inner plate 6 in the side wall assembly and the second rear cross member structure are connected together by structural glue and welding points to form the body. The frame sub-assembly, an...

Abstract

The invention discloses a rear beam structure, a body frame assembly and an automobile, and relates to the technical field of automobiles, comprising: a first rear beam upper plate and a second rear beam upper plate; a rear beam lower plate, a rear beam lower plate and a first rear beam lower plate The upper plate of the rear beam or the upper plate of the second rear beam is connected; the outer plate of the rear beam is connected with the upper plate of the second rear beam; the upper plate of the first rear beam and the lower plate of the rear beam form the first rear beam structure. The beam structure is used for sheet metal roof vehicles; the upper plate of the second rear beam, the lower plate of the rear beam and the outer plate of the rear beam form the second rear beam structure, and the second rear beam structure is used for the roof car; A rear cross member structure and a second rear cross member structure are respectively adapted to the sheet metal roof and canopy roof vehicles, and both the second rear cross member structure and the first rear cross member structure can be connected with the side panel outer panel and the D-pillar structure in the same connection form. Connection, realize the universal design of the rear beam structure, save design and production costs.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and more particularly, relates to a rear beam structure, a body frame assembly and an automobile. Background technique [0002] With the rapid development of the automobile industry, there are more and more options for automobiles. The rich selection of models has made people's requirements for automobiles not only limited to appearance, power, price, etc., but also put forward stricter vehicle configuration. The requirements of the car, especially for the appearance configuration are getting higher and higher, and the pursuit of the ultimate experience has become the consensus of more and more consumers. Therefore, a car with the ultimate experience will definitely stand out in the future car competition and become the heart of consumers. 's darling. [0003] At present, on the basis of the traditional sheet metal roof (including no sunroof, small sunroof and panoramic sunroof configuration...
