Embodiment Construction

[0024] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0025] In order to solve the problems in the prior art that the connection strength between the rear longitudinal beam rear cover assembly and other components is low, and the connection is easy to fail and open welding due to the small connection area, as the first aspect of the present invention, a rear Stringer rear cover assembly.

[0026] Such as Figure 1 to Figure 4 As shown, the rear side beam rear cover assembly includes a body 10 and a connecting portion 20. The middle part of the body 10 has an opening 11 and a first connecting plate 12 formed by turning over the material at the opening 11. The first connecting plate 12 moves away from the body. The connecting portion 20 is connect...

Abstract

The invention provides a rear girder rear cover plate assembly and a vehicle body. The rear girder rear cover plate assembly comprises a body and a connection part, wherein the middle part of the body is provided with an opening and a first connection plate formed when material at the opening is turned and folded, and the first connection plate extends towards the direction far away from the first surface of the body; and the connection part is connected with the first surface of the body around the circumferential edge of the opening. As both the first connection plate on the body and the independently-set connection part serve as assembly surfaces for being connected with other parts, the mounting area of the rear girder rear cover plate assembly is effectively increased, connection strength after the rear girder rear cover plate assembly is connected with other parts can be effectively improved, the problem of open welding failure can be effectively avoided, the structural strength of the vehicle body can be improved, the maintenance rate is reduced, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a rear longitudinal beam rear cover assembly and a vehicle body. Background technique [0002] The rear longitudinal beam rear cover is mainly used to close the rear longitudinal beam body so that the body can obtain sufficient bending and torsional rigidity, and at the same time provide installation support for the energy-absorbing box of the rear anti-collision beam, and withstand the impact force in the rear collision. Since the rear trailer device is generally arranged on the rear anti-collision beam, the vehicle body also needs to bear a relatively large pulling force when pulling other vehicles. [0003] In order to meet the structural strength requirements of the vehicle body under the above circumstances, it is necessary to continuously improve the structural strength of the rear part of the vehicle body. [0004] The rear longitudinal beam rear cover plate i...
