The invention relates to the technical field of automobile structures, in particular to a rear suspension mounting assembly structure, and aims to solve the technical problems that an existing rear suspension mounting assembly structure is low in mounting point rigidity and poor in structural continuity, and side collision force is not easy to transmit. According to the technical scheme, a rear suspension mounting bracket and a rear suspension mounting reinforcing plate are additionally arranged, and both the rear suspension mounting bracket and the rear suspension mounting reinforcing plate form a backward external expansion type structure. The rear floor longitudinal beam, the rear floor transverse beam, the doorsill reinforcing plate, the doorsill rear section, the rear floor longitudinal beam reinforcing plate, the rear suspension mounting threaded pipe and other parts around the rear floor longitudinal beam and the rear floor transverse beam are connected through welding spots to form a plurality of closed cavity structures, and the static rigidity and the dynamic rigidity of a rear suspension mounting point are improved. Meanwhile, a left-right and front-back continuous structure is formed, and the torsional rigidity and the first-order mode of the vehicle body are improved; a through structure connected with a cross beam is additionally arranged on a rear suspension mounting assembly of the rear floor assembly, and transmission of side collision force is facilitated.
Description
Technical field[0001]The present invention relates to the technical field of automotive structures, in particular a post-suspension mounting assembly structure.Background technique[0002]The rear suspension mounting assembly structure is used to install the structure of the components such as latter, and the structural stiffness is critical to the overall performance of the vehicle body. The existing rear suspension installation assembly structure has the following defects: 1) The static stiffness and moving stiffness of the structural mounting point are low; 2) The structure is discontinuous, affecting the transfer stiffness of the whole vehicle and the first order; 3) Parallel connection The structure is not conducive to the transmission of the side collision.Inventive content[0003]The present invention aims to solve the technical problem of low stiffness of the existing rear suspension mounting assembly, poor structural continuity, poor structure, and not easily transmitted by sid...
