For example, as shown in fig. 2 and 3, the through holes 2101a are two and arranged at intervals in the up-down direction. The number of the through holes 2101a and the number of the bolts may be specifically set according to the need, and are not limited to two, and may also be other values, which are not described herein again.
According to some embodiments of the present invention, as shown in fig. 3, the connecting portion 2101 is formed by stamping the portion of the mounting plate 210 toward the side close to the beam main body 10. That is, the connecting portion 2101 and the mounting plate 210 are formed as a single piece by press-molding the mounting plate 210, and in this way, the strength of the mounting plate 210 can be improved.

The reinforcing plate 2202 can improve strength, and the energy absorbing plate 2201 can absorb energy by the collapse of the plurality of bending portions 22011 when the beam body 10 is impacted, thereby reducing or preventing the beam body 10 from being impacted.
Specifically, the energy absorbing plate 2201 can be welded to the mounting plate 210.
As shown in fig. 2 and 3, specifically, an end of the energy absorbing plate 2201 away from the mounting plate 210 may refer to a rear side end of the energy absorbing plate 2201, i.e., the reinforcing plate 2202 is welded to the rear side end of the energy absorbing plate 2201.
As shown in fig. 4, according to some embodiments of the present invention, the mounting plate 210 has a first direction disposed along a length direction of the beam body 10 and away from a center of the beam body 10, the plurality of bending portions 22011 are sequentially disposed along the first direction, the energy absorbing plate 2201 has a height direction perpendicular to the mounting plate 210, and heights of the plurality of bending portions 22011 are gradually reduced along the first direction.
The energy absorbing assembly 20 may be provided at either the left or right end of the beam body 10, or at both the left and right ends of the beam body 10. For example, when the energy absorber assembly 20 is disposed at the right end of the beam body 10, "first direction" may refer to a direction from left to right in FIG. 4, and "height direction" may refer to a front-rear direction in FIG. 4. The height of the plurality of bent portions 22011 gradually decreases in the first direction, that is, the height thereof decreases as the bent portions 22011 are closer to the outer side of the beam body 10. "outboard" can refer to the side away from the center of the beam body 10, e.g., when the energy absorber assembly 20 is disposed at the left end of the beam body 10, "outboard" is the left side of the beam body 10; when the energy absorber assembly 20 is disposed at the right end of the beam body 10, the "outboard" side is the right side of the beam body 10. Since the front end surface of the rear bumper (i.e., the end surface closer to the rear side of the beam body 10) is not generally flat, the height of the plurality of bent portions 22011 gradually decreases in the first direction to maintain the distance between the reinforcing plate 2202 and the front end surface of the rear bumper at a uniform distance, and the plurality of bent portions 22011 can participate in energy absorption in a collision of the rear bumper.
Referring to the foregoing, when the energy absorbing assembly 20 is disposed at the left end of the beam body 10, the "first direction" can refer to the direction from right to left in fig. 4, and the energy absorbing process of the plurality of bending portions 22011 is referred to above and will not be described herein again.
As shown in fig. 4, according to some embodiments of the present invention, the size of the curved portion 22011 in the first direction gradually increases toward the mounting plate 210. The dimension of the curved portion 22011 in the first direction may refer to the width in the left-right direction in the figure, and the "direction close to the mounting plate 210" may refer to the direction from back to front, that is, each curved portion 22011 is tapered, which may improve the strength of itself and bring about better energy absorption effect.
According to some embodiments of the present invention, as shown in fig. 3, the reinforcing plate 2202 has a welding hole 2202a and a avoiding hole 2202b, and the welding hole 2202a is disposed on two opposite sides of the avoiding hole 2202 b. The welding hole 2202a can provide space for a welding gun to move along the welding hole 2202a for welding. Dodge hole 2202b can provide the space of dodging, for the buckle spare on the rear bumper provides the space of dodging.
For example, as shown in fig. 3, the two welding holes 2202a may be strip-shaped holes extending in the up-down direction, and the avoiding hole 2202b may be a rectangular hole extending in the left-right direction.
Another object of the present invention is to provide a vehicle.
