Sinusoidal crush can assembly

摘要

A sinusoidal crush can assembly for a bumper assembly includes a top wall, a bottom wall spaced from the top wall, and a pair of spaced side walls that extend between the top wall and the bottom wall to present a generally tubular and trapezoidal shape. The crush can assembly further includes a sinusoidal wave portion disposed along each of the walls from the rear end towards the front end. Each of the wave portions include peaks and troughs that define a sinusoidal wave depth, and the sinusoidal wave depth reduces gradually from the front end toward the rear end. Each of the peaks and the troughs are aligned with one another. The crush can assembly further includes a wave portion separator that extends angularly between adjacent ones of the wave portions to transition between each of the sinusoidal wave portions that are disposed along each of the walls.

主权项

1. A sinusoidal crush can assembly for use in a bumper assembly, comprising:
a top wall, a bottom wall spaced from said top wall, and a pair of spaced side walls extending between said top wall and said bottom wall, each of said top wall, said bottom wall, and said pair of side walls extending between a front end and a rear end, and said walls presenting an opening therebetween; each of said top wall, said bottom wall, and said pair of side walls including a sinusoidal wave portion extending between said rear end and said front end, each of said sinusoidal wave portions including a plurality of peaks and a plurality of troughs, wherein each of said peaks is curved outwardly relative to said opening and each of said troughs is curved inwardly relative to said opening, said peaks disposed along said top wall and said bottom wall are aligned with said peaks disposed along said side walls, said troughs disposed along said top wall and said bottom wall are aligned with said troughs disposed along said side walls; and a plurality of wave portion separators each extending angularly between said top wall and one of said side walls or angularly between said bottom wall and one of said of side walls.
