Description

Background technique

The rear shock absorber mounting plate of the vehicle body is located on the outer surface of the inner plate of the wheel house on the side wall of the vehicle body. In the traditional structural scheme, the rear shock absorber mounting plate is generally welded to the outer side of the inner plate of the rear wheel house in a flat structure or a box structure to fix the rear shock absorber. The two installation points of the shock absorber bear the shock and vibration excitation input from the road surface by the rear shock absorber at the same time.

In the prior art, in order to increase the local rigidity of the rear shock absorber installation part, two vertical through-bosses are added on the basis of the ordinary shock absorber reinforcement plate, and the two bosses are arranged at intervals between the two sides of the shock absorber body. side, and arrange the mounting point of the shock absorber on the boss, in order to increase the Y-direction stiffness of the shock absorber mounting plate.

However, although this structure can improve the local rigidity on the basis of the traditional ordinary flat structure, its limitations are also obvious: 1) The mounting plate of the rear shock absorber is generally integrally formed, and the actual parts are due to the M-shaped boss structure. , there must be different degrees of molding thinning or even excessive thinning, the strength of the mounting point is limited by this, the improvement of material grades is extremely limited, and the problem of durable cracking of sheet metal and solder joints is high; 2) The mounting plate of the rear shock absorber is an ordinary single layer The structure, regardless of the strength or local stiffness, has limited improvement; 3) Under the condition of a certain material, the structural formability is inversely proportional to the height of the boss forming, so the risk of forming and cracking of the boss structure of the rear shock absorber mounting plate is high; 4) Molding restrictions lead to the limitation of the depth of the M-shaped boss, which will directly cause the limited effect of improving the stiffness of the main rear shock absorber mounting plate. In the case of medium and large SUVs, sports cars and models with high performance requirements, the actual use scenarios are obviously insufficient .
