The invention belongs to the technical field of automobile door frames, and provides a laser welding door frame which is formed by continuous rolling forming of a sheet metal, the sheet metal is divided into a first sheet metal part, an automobile door outer side sheet metal part, a second sheet metal part and a supporting sheet metal part, the inner side face of the first sheet metal part and the inner side face of the second sheet metal part are overlapped and attached, and the first sheet metal part and the second sheet metal part are arranged on the supporting sheet metal part. A supporting pocket part is formed after the supporting plate part is bent, an extending section is arranged on the supporting plate part, the inner side face of the extending section is attached to the inner side face of the second plate part in an overlapped mode, and a laser welding connecting structure is arranged among the extending section, the first plate part and the second plate part. The door frame has the advantages that the overall strength of the whole door frame is guaranteed, meanwhile, manufacturing materials of the door frame are saved, the weight of a vehicle body is reduced under the condition that the rigidity of the door frame is not affected, and the production cost is reduced.

    本发明属于汽车门框技术领域,提供了一种激光焊接的门框,该门框由一块板料经连续滚压成型而成,该板料分为第一板料部、车门外侧板料部、第二板料部以及支撑板料部,第一板料部内侧面与第二板料部的内侧面重叠贴合,支撑板料部经弯折后形成有支撑口袋部,支撑板料部上具有延伸段,延伸段的内侧面与第二板料部的内侧面重叠贴合,延伸段、第一板料部以及第二板料部之间具有激光焊连接结构。本发明的优点在于既保证了整个门框的整体强度,同时又节省了门框的制作材料,不影响门框刚度的情况下,减轻车身重量,降低了生产成本。
