Title: BENDABLE ROAD-COLUMN FOR ELASTICALLY DISSIPATING ENERGY
Abstract:
A bendable road-column for elastically dissipating energy, comprising a bottom support column (1), a first plate spring (2), a transition column (3), second plate springs (4), and bending columns (5); the bottom support column (1) is mounted on the ground; the transition column (3) and a plurality of the bending columns (5) are sequentially connected to one another from the bottom by means of revolute joints; the first plate spring (4) is mounted between the bottom support column (1) and the transition column (3); the second plate springs (4) are mounted between the transition column (3) and the bending column (5) and between the bending columns (5); the bending columns (5), transition column (3), and bottom support column (1) can rotate relative to one another; by designing stop blocks or fixture blocks between columns, mutual rotation between columns satisfies the design requirements; the plate springs serve the function of buffering during rotation. By designing the road-column as a structure of hinging a plurality of columns, when colliding with a vehicle, the road-column can enclose the front of the vehicle by means of hinge rotation and absorb collision energy by means of the deformation of plate springs, reducing collision damage, having a better usage effect.
