The fourth reinforcing protrusion 42 is formed to correspond to the first reinforcing protrusion 11 located at the outer side, and the other first reinforcing protrusion 11 is formed at a corresponding position between the fourth reinforcing protrusion 42 and the third reinforcing protrusion 41, so that the damper installation region 111 can have a better supporting strength.
In the present embodiment, in order to provide better supporting strength for the shock absorber mounting region 111, a lateral reinforcing protrusion 43 is further disposed between the fourth reinforcing protrusion 42 and the third reinforcing protrusion 41, and is just abutted against the corresponding position of the middle first reinforcing protrusion 11 to provide supporting force for the same.
In order to improve the supporting force provided by the fourth reinforcing protrusion 42, a fifth reinforcing protrusion 44 is further arranged at an interval outside the fourth reinforcing protrusion 42, the third reinforcing protrusion 41, the fourth reinforcing protrusion 42 and the fifth reinforcing protrusion 44 are sequentially arranged at an interval, the third reinforcing protrusion 41 and the fourth reinforcing protrusion 42 are connected through a transverse reinforcing protrusion 43, the distance between the third reinforcing protrusion 41 and the fourth reinforcing protrusion 42 is larger than the distance between the fourth reinforcing protrusion 42 and the fifth reinforcing protrusion 44, and the end portions of the fourth reinforcing protrusion 42 and the fifth reinforcing protrusion 44 are connected to obtain a better supporting effect.
To sum up, the first reinforcing protrusion 11 on the main body plate 1 is obtained by stamping, and although the main body plate 1 is of an integral M-shaped boss structure, the middle part of the profile of the main body plate 1 is provided with a through hole, so that the stamping forming difficulty can be greatly reduced, and the M-shaped boss can greatly increase the protruding height of the main body plate 1, which is very beneficial to improving the dynamic stiffness of the damper mounting 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 higher, and the lightweight design is facilitated; the forming difficulty of the main body plate 1 and the connecting plate 3 is reduced, the limitation of material marks can be further released, materials with higher strength grades can be used, and the problems of endurance fatigue cracking of a metal plate of a mounting plate body of a shock absorber after the traditional automobile type and fatigue endurance welding spot cracking with high problems 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 at the peripheries of two mounting areas of the shock absorber. The material thickness around 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 also be quickly improved.
The abutting panel 32 abuts against the connecting panel 115 and the supporting panel 114 located at the outer side, and the abutting panel 32 also abuts against the damper mounting region 111, so that welding can be facilitated, and meanwhile, the contact area between the abutting panel 32 and the inner wall of the cavity of the first reinforcing protrusion 11 is increased. The abutting panel 32 is abutted against the shock absorber mounting area 111 and the periphery thereof to form a double-layer plate structure, the material thickness of the periphery of a direct stress point is doubled, the strength of the rear shock absorber mounting plate assembly can be rapidly improved, and the static rigidity and the dynamic rigidity of the shock absorber mounting area 111 can also be rapidly improved.
