Utility model content
The utility model, for solving the defect of prior art, provides a kind of and can meet energy-absorbing requirement and be conducive to the aluminum alloy energy-absorption box for automobile buffer beam of light-weight design.
Alleged by the utility model, problem solves by the following technical programs:
A kind of aluminum alloy energy-absorption box for automobile buffer beam, be made up of mount pad and the energy-absorption box body being positioned at mount pad top, described energy-absorption box body forms trapezoid or inverted trapezoidal by top board and upper and lower symmetrically arranged side plate, and the energy-absorption box body left and right sides is permeable structures.
The above-mentioned aluminum alloy energy-absorption box for automobile buffer beam, when energy-absorption box body is trapezoid, side plate angle of inclination a is 10 ° ~ 30 °; When energy-absorption box body is inverted trapezoidal, side plate angle of inclination a is-10 ° ~-30 °.
The above-mentioned aluminum alloy energy-absorption box for automobile buffer beam, described energy-absorption box body is also provided with gusset, and gusset is between two side plates, and gusset two ends are affixed top board and mount pad respectively.
The above-mentioned aluminum alloy energy-absorption box for automobile buffer beam, described gusset arranges 1 ~ 3 piece.
The above-mentioned aluminum alloy energy-absorption box for automobile buffer beam, the corner of described mount pad is provided with mounting hole.
The utility model takes into account energy-absorbing and weight-saving requirement and a kind of aluminum alloy energy-absorption box of designing for solving energy-absorption box.Described energy-absorption box makes it have by modified node method design the energy-absorbing effect being better than routine " day " font, " mouth " font energy-absorption box, compares hexagon energy-absorption box and significantly reduces deadweight.The utility model is aluminum alloy material, and through forming process extrusion molding, forming characteristics is stablized, and the design of many muscle makes structure more stable.Through cae analysis, deflection of the present utility model and energy absorption all meet related request.Adopt the utility model to make the integral structure of automobile buffer beam compare general structure can alleviate 10-25%, greatly reduce the quality of anticollision beam assembly, meet the designing requirement of automotive light weight technology.
