Embodiment Construction

[0034] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0035] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0036] This embodiment relates to a force transmission structure at the rear of the vehicle body, wherein the vehicle body in this embodiment is specifically the body of a car model, and the force transmission structure at the rear of the vehicle body in this embodiment is specifically used to form the body that is excited by the body. The conduction in the rear part is expected to improve the transmission of the excitation to the rear part of the vehicle body, thereby improving the crash performance, and at the same time improving the stiffness performance of the rear part of the vehicle body.

[0037] For specific settings, such as figure 1 As shown, in the rear force transmission str...

Abstract

The invention provides a vehicle body rear part force transmission structure which is used for forming transmission of excitation of a vehicle body in the rear part of the vehicle body, and the vehicle body rear part force transmission structure comprises a rear floor cross beam, a shelf, and a first force transmission ring structure which is formed by two rear floor longitudinal beams, a rear shock absorber reinforcing plate and a C column. According to the vehicle body rear portion force transmission structure, through the first force transmission ring structure formed by the rear floor cross beam, the shelf, the rear floor longitudinal beams on the two sides, the rear shock absorber reinforcing plate and the C columns, the force transmission performance of a rear shock absorber installation area on the rear portion of the vehicle body can be improved, and the safety risk of a driver and passengers in the vehicle can be reduced.

Description

technical field [0001] The invention relates to the technical field of car body structures, in particular to a force transmission structure at the rear of a car body. Background technique [0002] In vehicles, taking a car as an example, the rear structure of the body plays a vital role in the force transmission and NVH performance of the vehicle body. A high-performance rear structure can significantly improve the driving comfort of the vehicle, and can also improve the driving safety factor. [0003] In the current car body rear structure, for the excitation of the rear shock absorber installation area, due to the interruption and misconnection of the force transmission channel in the rear body force transmission structure to which this area belongs, and the rigidity of the rear shock absorber installation area Not enough. When the vehicle collides, the interruption or misconnection of the power transmission channel at the rear of the vehicle body is prone to bending, wh...
