The invention provides an energy-absorbing board, an energy-absorbing device, a steering column and a vehicle.The energy-absorbing board comprises a bottom board and energy-absorbing bands arranged above the bottom board. First ends of the energy-absorbing bands are connected with the bottom board. Second ends of the energy-absorbing bands are free ends. When the energy-absorbing board is mounted onto the steering column of the vehicle, collision-induced impact force of the steering column is absorbed by tensile deformation of the energy-absorbing bands and working of the position between the steering column and a crimping tool against friction force in order to absorb collision energy. Therefore, the crumpling energy-absorbing feature of the steering column is improved for preventing the steering column from piercing into a driving cab when the vehicle collides so that life security of a driver is not threatened.
