Moreover, the split type design of the first reinforcing piece 1 and the second reinforcing piece 2 reduces the weight and cost of the reinforcing plate, and meanwhile, the difficulty in connection matching between the reinforcing plate and the inner door plate 3 is reduced, and the qualification rate of finished products is greatly improved. In addition, generally, the first reinforcement and the second reinforcement are both covered at the splice-welded portion of the door inner panel.

In a preferred embodiment, the flange 12 comprises a cambered surface portion 121 and a plane portion 122 which are continuously distributed in the longitudinal direction; wherein the arc surface portion 121 is connected between the main body plate 11 and the plane portion 122, and the arc surface portion 121 extends in a direction away from the door inner panel 3; the planar portion 122 is parallel or approximately parallel to the door inner panel 3.

The arrangement is that the cavity structure is arranged between the main body plate 11 and the vehicle door inner plate 3, so that the main body plate 11 and the vehicle door inner plate 3 are matched to form a three-dimensional structure, and compared with the main body plate 11 which is completely attached to the vehicle door inner plate 3, the structure strength is better, and the structure strength and the rigidity lost due to the split design of the reinforcing plate are more deeply compensated.

In an alternative embodiment, a portion of the second plate portion 112 is raised in a direction away from the door inner panel 3 to form the closed compartment 5. That is, a part of the second plate portion 112 is attached to the door inner panel 3 and fixed thereto by the rivet 4, and the remaining part bulges. By the design, the first reinforcement member 1 and the second reinforcement member 2 are small in structure, low in design cost and easy to adjust.
