In some embodiments, the waist line reinforcing plate 3 is welded on the inner sheet metal of the vehicle door, so that the static rigidity of the upper end of the inner sheet metal of the vehicle door can be increased through the waist line reinforcing plate 3, and vibration of the inner sheet metal of the vehicle door caused by excitation when the door is closed is avoided.
Still further, the static rigidity reinforcing structure of the sheet metal in the vehicle door further comprises an open continuous flanging 4.
Specifically, the open-hole continuous flange 4 includes a first open-hole continuous flange 41 corresponding to a first open-hole, a second open-hole continuous flange 42 corresponding to a second open-hole, a third open-hole continuous flange 43 corresponding to a third open-hole, and a fourth open-hole continuous flange 44 corresponding to a fourth open-hole. In a specific implementation, the reinforced pits may be punched at the hole positions of the first hole, the second hole, the third hole and the fourth hole, and then the hole is turned over, so as to strengthen the static rigidity around the holes. Further, the lengths of the first hole continuous flange 41, the second hole continuous flange 42, the third hole continuous flange 43 and the fourth hole continuous flange 44 are not smaller than a preset length threshold, and the lengths are in a zigzag shape or a U shape with the outer edge of the corresponding hole, so that the static rigidity of the hole position is not greatly reduced due to the hole.
