Embodiment 1
[0033] Example 1: figure 1 and figure 2 It is an embodiment of a crash box with a square section.
[0034] Such as figure 1 As shown, the square-section impact energy-absorbing box 1 is composed of multiple three-dimensional energy-absorbing areas 3 and type I folding energy-absorbing areas 5, and the three-dimensional energy-absorbing areas 3 and type I folding energy-absorbing areas 5 are arranged at intervals from top to bottom. Arranged in different ways; crash boxes of different heights can be obtained by superimposing several three-dimensional energy-absorbing areas and folding energy-absorbing areas along the axial direction. The Type I folding energy-absorbing area 5 forms circularly arranged rotary folding concave corners through crease lines and combined with rotating folding methods. The rotary folding concave corners in the Type I folding energy-absorbing area 5 are Type I folding concave corners 4. Type I folded concave angle 4 refers to the folded concave ang...
Embodiment 2
[0035] Example 2: image 3 and Figure 4 It is an embodiment of the hybrid type I crash crash box.
[0036] Such as image 3 As shown, the hybrid type I crash energy-absorbing box 8 is composed of a three-dimensional energy-absorbing area 3 and a type-I folding energy-absorbing area 5, and the three-dimensional energy-absorbing area 3 and the type I folding energy-absorbing area 5 are arranged in a top-to-bottom cross arrangement. Among them, one type I folded energy absorbing area 5 is arranged between two three-dimensional energy absorbing areas 3 , and two type I folded energy absorbing areas 5 are arranged continuously between the other two three-dimensional energy absorbing areas 3 . Each Type I folding energy-absorbing area 5 has a circle of rotary folding concave angles arranged in a circle, and each Type I folding energy-absorbing area 5 contains four Type I folding concave angles 4; Figure 4 As shown, there are three type I folding energy absorbing regions 5 in th...
Embodiment 3
[0037] Example 3: Figure 5 and Figure 6 It is an embodiment of the hybrid type II crash crash box.
[0038] Such as Figure 5As shown, the hybrid type II crash energy-absorbing box 9 is composed of a three-dimensional energy-absorbing area 3 , a type-I folding energy-absorbing area 5 and a type-II folding energy-absorbing area 11 . Among them, the type I folding energy-absorbing area 5 and the type II folding energy-absorbing area 11 are arranged at intervals on the hybrid type II crash energy-absorbing box 9 . The difference between the Type I folding energy-absorbing area 5 and the Type II folding energy-absorbing area 11 is that the rotary folding concave corner in the Type I folding energy-absorbing area 5 is the Type I folding concave angle 4, and the rotary folding concave angle in the Type II folding energy-absorbing area 11 is The folding reentrants are type II folding reentrants 10 , the rotation direction of type I folding reentrants 4 is clockwise, and the rota...
