Automobile seat beam structure

The invention discloses an automobile seat beam structure. The automobile seat beam structure comprises a seat beam body (1) and seat front installing plate assemblies (2). The cross section of the seat beam body (1) is in a U shape. The cross sections of the seat front installing plate assemblies (2) are in a U shape. The seat front installing plate assemblies (2) are installed inside the seat beam body (1). The U-shaped section of the seat beam body (1) is totally attached to the U-shaped sections of the seat front installing plate assemblies (2). The seat front installing plate assemblies (2) are provided with projection welding bolts. The seat front installing plate assemblies (2) are installed on the seat beam body (1) through cooperation of the projection welding bolts and passing holes (3). According to the automobile seat beam assembly structure, a front seat beam is made of high-strength steel materials, the cold punch forming technology is adopted, integral punch forming is achieved through the structural shape facilitating punch forming, and the lightweight of an automobile body is achieved while the requirement of a target market collision regulation is met.
