The invention relates to an elastic buffering and plastic overturning parallel type energy absorption assembly which comprises a cylindrical thin-wall component and a compression spring and further comprises an overturning seat. The elastic buffering and plastic overturning parallel type energy absorption assembly is characterized in that the center of the compression spring and that of the cylindrical thin-wall component are arranged on a same straight line; the overturning seat comprises a seat body and a boss, the boss is integrally in circular arc connection with the seat body, one end of the cylindrical thin-wall component sleeves the boss, and the other end of the cylindrical thin-wall component is a free end; one end of the compression spring is fixedly connected with the boss, the other end of the compression spring is a stress end, and the stress end extends out of the free end of the cylindrical thin-wall component. The invention has the benefits: the structure is simple, buffering and energy absorption functions are achieved, and safety and protection property are improved. Compared with a plastic collapse buckling energy-absorption structure, the structure of the elastic buffering and plastic overturning parallel type energy absorption assembly has longer buffering distance and more stable energy absorption capacity.
