Embodiment Construction
[0021] see figure 1 , Figure 4 , The composition of the present invention includes a beam 2 and energy-absorbing boxes 1 arranged symmetrically on both sides of the beam.
[0022] see figure 2 , in order to adapt to changes in the design of the outer profile of the automobile skin 12, the bumper beam 2 basically meets the requirements of the skin-fitting design, the beam 2 of the present invention is a three-section structure, and the arc radii of each section of the beam are equal, wherein, The two beam side sections 2-1 are bent inwardly with respect to the beam middle section 2-2 by a kink angle α. In other words, point b on the beam is the bending point, and the left and right points adjacent to the bending point fall on the side section of the beam and the middle section of the beam respectively, and the angle between the tangent lines b1 and b2 of the above two points is α. When the above-mentioned structure is used to make the crossbeam, it is sufficient to bend t...
