As shown in fig. 1, the front impact beam assembly 100 includes: a beam body 10 and a reinforcement plate 20. The cross member body 10 includes at least a front portion 11 located on the front side of the vehicle body and side wall portions 12 forming both sides of the front portion 11. That is, in the horizontal direction, the cross member body 10 is generally of a structure of "C" shape open to the rear side.

Specifically, the cross member body 10 extends in the left-right direction, and both ends of the cross member body 10 extend to the rear side. A part of the cross member body 10 is located on the front side of the vehicle body, and the other part of the cross member body 10 is located on both sides of the vehicle body.

In some embodiments of the present invention, as shown in fig. 2-4 in conjunction with fig. 1, the beam body 10 protrudes rearward to form a bending region 111. That is, the cross member body 10 has a portion recessed rearward, so that the front side of the cross member body 10 has different force-receiving surfaces, and in the case where the cross member body 10 is struck by an external force, the external force can be dispersed to the different force-receiving surfaces, thereby improving the structural bending resistance of the cross member body 10 and preventing breakage from occurring even in a high-speed collision.

In order to further enhance the structural bending resistance of the beam body 10, a part of the reinforcing plate 20 extends forward to form an abutting portion 21, and the abutting portion 21 abuts against the bending region 111, wherein an abutting surface of the abutting portion 21 is a plane. That is, by the abutting portion 21 being engaged with the bent region 111, the abutting portion 21 can apply an acting force against the impact force to the bent region 111, enhancing the deformation resistance of the cross beam body 10. Since the surface of the bending region 111 that mates with the abutting portion 21 is an arc-shaped surface, the bending region 111 spaces the abutting portion 21 from the beam body 10.

Further, as shown in fig. 4, the abutting portion 21 is spaced apart from the cross beam body 10 by the bent region 111. Therefore, the upper sides of the beam body 10 and the reinforcing plate 20 are both formed to extend backwards and upwards, and the lower sides of the beam body 10 and the reinforcing plate 20 are both formed to extend backwards and downwards, buffer zones can be formed on two sides of the bending zone 111, that is, the reinforcing plate 20 and the beam body 10 jointly enclose the buffer zones, so that when a vehicle collides with a pedestrian, the beam body 10 of the front anti-collision beam assembly 100 has a space which deforms backwards, the injury to the pedestrian is reduced, and because the abutting part 21 of the reinforcing plate 20 abuts against the bending zone 111, the beam is not easy to break under the condition of being impacted by a large external force.

In an alternative embodiment, the upper side upward extending part of the beam body 10 and the reinforcing plate 20 is welded, and the lower side downward extending part of the beam body 10 and the reinforcing plate 20 is welded. That is, the reinforcing plate 20 is fixedly attached to the cross member body 10 by attaching the upper and lower sides of the reinforcing plate 20 to the upper and lower sides of the cross member body 10. For example, the cross member body 10 and the reinforcing plate 20 may be connected by spot welding.

In other embodiments of the present invention, the left end of the beam body 10 exceeds the left end of the reinforcing plate 20, the right end of the beam body 10 exceeds the right end of the reinforcing plate 20, and the front anti-collision beam assembly 100 further includes: the energy absorption boxes 30 are arranged at two ends of the beam body 10 beyond the reinforcing plate 20.

That is, the reinforcing plate 20 does not interfere with the attachment of the crash box 30 when the structural bending resistance of the beam body 10 is improved. Therefore, the buffering capacity of the front anti-collision beam assembly 100 can be improved through the two energy absorption boxes 30, and the safety of the front anti-collision beam assembly 100 is further improved.

Alternatively, the crash box 30 is attached to the beam body 10 by welding. Thus, the crash box 30 and the beam body 10 can be integrally mounted to the vehicle body via the crash box 30 or the beam body 10. For example, the rear end of the crash box 30 is provided with an end cap 31, and the end cap 31 is provided with a plurality of bolt holes 311. Thus, the rear end of the crash box 30 can be bolted to the body side rail.

In a further alternative example, the crash box 30 increases in cross-section from front to back. That is, the cross section of the front side of the energy-absorbing box 30 is smaller than the cross section of the rear side, so that the connecting surface between the energy-absorbing box 30 and the beam body 10 can be reduced, the buffering capacity of the energy-absorbing box 30 can be enhanced, and the safety of the front anti-collision beam assembly 100 can be improved.

In a further alternative example, as shown in fig. 1, the portion of the beam body 10 beyond the reinforcing plate 20 is further provided with a drag hook positioning hole 121.
