In summary, the first reinforcing protrusion 11 on the main body plate 1 is obtained by stamping, and although the main body plate 1 is in an integral M-shaped boss structure, the through hole is formed in the middle of the profile of the main body plate 1, so that the stamping forming difficulty can be greatly reduced, and the protruding height of the main body plate 1 can be greatly increased by the M-shaped boss, which is very beneficial to the dynamic stiffness improvement of the shock absorber installation area 111; the connecting plate 3 and the main body plate 1 are designed and processed separately, so that the forming difficulty can be reduced, the material thickness and the material thickness of the connecting plate 3 and the main body plate 1 can be defined and improved respectively, the local reinforcement pertinence is strong, the forming difficulty is small, the design freedom is larger, and the lightweight design is facilitated; the molding difficulty of the main body plate 1 and the connecting plate 3 is reduced, the limit of material marks can be further released, materials with higher strength grade can be used, and the problems of durable fatigue cracking of the sheet metal of the mounting plate body of the rear shock absorber of the traditional vehicle type and high-occurrence fatigue durable welding spot cracking can be greatly improved; the outer edge of the connecting plate 3 is connected with the main body plate 1 around the through hole, and a double-layer plate structure can be formed around two mounting areas of the shock absorber. The thickness of the peripheral material of the direct stress point is doubled, so that the strength of the rear shock absorber mounting plate assembly can be quickly improved, and the static rigidity and the dynamic rigidity of the shock absorber mounting area 111 can be quickly improved.
The supporting panel 32 is supported on the connecting panel 115 and the supporting panel 114 located on the outer side, the supporting panel 32 is also supported on the shock absorber installation area 111, so that the contact area between the supporting panel 32 and the inner wall of the cavity of the first reinforcing protrusion 11 is increased while welding is facilitated. The supporting panel 32 is also supported on the shock absorber installation area 111 and the periphery thereof to form a double-layer plate structure, and the thickness of the peripheral material of the direct stress point is doubled, so that the strength of the rear shock absorber installation plate assembly can be rapidly improved, and the static rigidity and the dynamic rigidity of the shock absorber installation area 111 can be rapidly improved.
