Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, the detailed description of the invention of the present invention is made further details of
Explanation, it is therefore an objective to help those skilled in the art that design, the technical scheme of the present invention are had more complete, accurate and deep reason
Solve, and contribute to its enforcement.
As it is shown in figure 1, be a kind of front anticollision beam of automobile assembly 100 using energy-absorption box of the present invention, be suitable to electric automobile, bag
Include collision prevention girders body 101, energy-absorption box 102 and the collision prevention girders installing plate 113 being connected with energy-absorption box 102.As in figure 2 it is shown, the present invention
Energy-absorption box 102 use aluminium section bar to make and inside has cavity, the cross section of energy-absorption box 102 is the figure of eight, this cross section
Energy-absorption box energy-absorbing is bigger.
As shown in Figures 2 and 3, the energy-absorption box 102 of the present invention is to be octagon and both ends open, interior by two cross sections
The energy-absorbing body 103 of portion's hollow is formed by connecting, and by raw material extrusion molding during making, uses the energy-absorption box that aluminium section bar is made
The good rigidity of 102, lightweight, make anticollision beam assembly 100 meet car load lightweight requirements.
As it is shown in figure 1, energy-absorption box 102 arranges two on collision prevention girders body 101, two energy-absorption boxes 102 are along collision prevention girders originally
The length direction of body 101 is arranged, two energy-absorption boxes 102 lay respectively at one end of collision prevention girders body 101, each energy-absorption box 102
One end is welded to connect with collision prevention girders body 101, and the other end is welded to connect with collision prevention girders installing plate 113.As shown in Figures 2 and 3, respectively
Two energy-absorbing bodys 103 of individual energy-absorption box 102 are the width layout along collision prevention girders body 101, the width of collision prevention girders body 101
Paralleling with Z-direction in degree direction, the length direction of collision prevention girders body 101 is paralleled with Y-direction, the length direction of energy-absorbing body 103 and X
To parallel.
As shown in Figures 2 and 3, the cross section of energy-absorbing body 103 is octagon structure, and energy-absorbing body 103 has eight
Sidewall, two energy-absorbing bodys 103 in Z-direction for being symmetrical arranged.Between adjacent two sidewalls of energy-absorbing body 103, there is a circle
The incline line of arcuation, eight incline lines of energy-absorbing body 103 be circumferentially followed successively by first incline line the 105, second incline line 106,
