Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model is for energy-absorption box structural manufacturing process complex structure in prior art, and the problem that manufacturing cost is high provides a kind of anti-collision beam energy absorbing box structure of modular design.
As shown in Figure 1, the anti-collision beam energy absorbing box structure of a kind of modular design that the utility model embodiment provides, comprises energy-absorption box assembly 1, and described energy-absorption box assembly 1 comprises two symmetrically arranged energy-absorption box branch units 11.
As shown in Figure 2, described energy-absorption box branch unit 11 comprises top board 101, from these top board 101 both sides bending downwards the side plate 102 tilting perpendicular to this top board 101 or to these top board 101 outsides, the connecting panel 103 bending laterally from these side plate 102 root edges, described connecting panel 103 and top board 101 be arranged in parallel.Described top board 101 centers are provided with arc groove 104, described arc groove 104 is through described top board 101 surfaces, identical with cavity 2 axial directions of described energy-absorption box assembly, arc groove structure has played the effect of reinforced rib, strengthen on the whole the structural strength of energy-absorption box branch unit, as shown in Figure 3.Described top board 101 is provided with welding equipment datum hole 105, the described datum hole 105 that is welded is symmetrically distributed in arc groove 104 both sides, and every side is provided with 2, and described side plate 102 adopts arc transition with the junction of described top board 101, connecting panel 103, reduce stress concentration phenomenon, as shown in Figure 1.
