Two protective beams are symmetrically arranged up and down inside the door body. Flanges are respectively formed by turning up the peripheries of the top ends and bottom ends of the two protective beams. A plurality of support plates are arranged between the front end face and the rear end face inside the flange. The plurality of support plates are parallel to each other and are evenly spaced along the length direction of the protective beam. Reinforcing components are symmetrically arranged between the two ends of the support plate and the flange. The reinforcing component includes a first inclined plate, a second inclined plate, and a third inclined plate symmetrically arranged on both sides of the support plate. Adjacent first inclined plates, second inclined plates, and third inclined plates are spaced parallel to each other, and a triangular stable structure is formed between the first inclined plate, the second inclined plate, and the third inclined plate and the support plate and the flange. The second inclined plate is located inside the third inclined plate, and the first inclined plate is located inside the second inclined plate.
[0005] Further, two connecting beams arranged vertically are symmetrically arranged between the two protective beams. The two connecting beams are spaced and parallel to each other.
[0006] Further, edge reinforcing ribs are arranged at the edges of the front end face and the rear end face of the connecting beam.
[0007] Further, two vertically arranged reinforcing protrusions are symmetrically arranged on the front end face and the rear end face of the connecting beam. The two reinforcing protrusions are parallel to each other.
[0008] Further, a plurality of first connecting reinforcing ribs are arranged at intervals from top to bottom between the two reinforcing protrusions.
[0009] Further, on one side of the strengthening protrusion close to the edge strengthening rib, second connecting strengthening ribs connected to the edge strengthening rib are arranged at intervals from top to bottom, and the second connecting strengthening rib and the first connecting strengthening rib are on the same central axis.
[0010] The beneficial effects of the present utility model are as follows:
[0011] Through the cooperative setting of the protection beam, flanging, support plate, strengthening component, first inclined plate, second inclined plate, and third inclined plate, when the car door is impacted and collapses, the protection beam intercepts and resists the car door and external impacts. The flanging, support plate, and strengthening component increase the structural strength and rigidity of the protection beam. When the protection beam is impacted, the impact force received by the front flanging is supported and resisted by the support plate, preventing large deformations of the flanging and protection beam. Moreover, the strengthening component formed by the first inclined plate, second inclined plate, and third inclined plate forms a triangular stable structure with the support plate and flanging to further increase the structural stability of the support plate, resist and support external impacts, enable the protection beam to effectively resist external impacts, and improve the anti-collision performance and safety of the car door.

At the peripheries of the top and bottom ends of the two protective beams 2, flanges 3 are respectively formed by folding upwards and downwards. The flanges 3 increase the wall thickness of the protective beams 2, enhance their structural strength and rigidity, and improve their protective performance. Between the front end face and the rear end face inside the flanges 3, a plurality of support plates 4 are arranged. The plurality of support plates 4 are parallel to each other and are evenly spaced along the length direction of the protective beam 2. The bottom surfaces and top surfaces of the upper support plate 4 and the lower support plate 4 are respectively connected to the protective beam 2, which further increases the structural strength and rigidity of the protective beam 2. And when the front end face of the protective beam 2 is impacted, its front end face and the flanges 3 are supported and resisted by the support plates 4, preventing large deformations of the flanges and the protective beam.
[0018] Reinforcing components are symmetrically arranged between the two ends of the support plate 4 and the flanges 3. The reinforcing components further increase the structural strength and rigidity of the protective beam 2 and make the structure between the support plate 4 and the flanges 3 more stable. The reinforcing components include a first inclined plate 501, a second inclined plate 502, and a third inclined plate 503 that are symmetrically arranged on both sides of the support plate 4. The adjacent first inclined plate 501, second inclined plate 502, and third inclined plate 503 are arranged parallel to each other at intervals, and a triangular stable structure is formed between the first inclined plate 501, second inclined plate 502, third inclined plate 503 and the support plate 4, flanges 3. The second inclined plate 502 is located inside the third inclined plate 503, and the first inclined plate 501 is located inside the second inclined plate 502.
