ABSTRACT:
An elastic energy storage device has an energy storage unit which has an axial rod penetrating through a plurality of rotary disks and spiral springs. One side of each rotary disk is protruded with an outer edge buckling post and another side thereof is installed with an inner edge buckling post. Each two rotary disks are installed with a spiral spring. The casing is installed with a unidirectional power output shaft for driving the first rotary disk of the energy storage unit to rotate. The speed change box has an input shaft and an output shaft. The input shaft is connected or engaged to the rotary disk; and one of the rotary disks of the energy storage unit at an innermost side has a function of driving the input shaft to rotate. Thereby, the at least one spiral spring stores energy through a flywheel and then release the energy steadily.
