The long side 11 is arranged curved. The two long sides 11 are substantially parallel and the two short sides 12 are substantially parallel. The body panel 10 has an outer surface 13 and an inner surface 14 disposed opposite the outer surface 13. The side plate 20 is bent from the long side 11 with respect to the main body plate 10. The side panel 20 is integrally formed with the main body panel 10. The two side plate members 20 are arranged at an included angle with each other. A bell-mouth-shaped receiving groove is formed between the two side plates 20. The mounting plate 30 is bent from the edge of the side plate 20 away from the main body plate 10 to the side plate 20. The parallel orientation of the mounting plate 30 to the body plate 10 is not limited to absolute parallelism, but does not preclude the mounting plate 30 being substantially parallel to the body plate 10, i.e., the mounting plate 30 appears to be parallel to the body plate 10. The thicknesses of the main body panel 10, the side panel 20, and the mounting panel 30 are substantially the same to facilitate the molding of the impact beam 100. The two mounting plates 30 are approximately in a flush state, so that the two mounting plates 30 can provide a platform for mounting the energy absorption block, and the energy absorption block is conveniently combined with the anti-collision beam 100. The impact beam 100 is formed by a die-casting process. The shape of the impact beam 100 can be freely designed as required, so that the impact beam 100 meets the requirements of light weight and high strength. The body panel 10 is slightly bent at a portion between both ends to make the structural strength of the body panel 10 greater, so that the impact resistance of the impact beam 100 is more excellent.
