Abstract: A passive exoskeleton based on energy flow characteristics of a foot-ankle complex includes a first passive exoskeleton. The first passive exoskeleton includes an energy distribution mechanism, a strike-recipient mechanism and a wearing fixing assembly. The energy distribution mechanism is connected to the strike-recipient mechanism, and the energy distribution mechanism is also connected to the wearing fixing assembly. The energy distribution mechanism includes a ratchet wheel shaft, a left torsional spring, a right torsional spring and a middle guide wheel respectively sleeved on the ratchet wheel shaft. The middle guide wheel is connected to the wearing fixing assembly through an ankle joint power-assisted cord. The ratchet wheel shaft is connected to the strike-recipient mechanism, the strike-recipient mechanism drives the ratchet wheel shaft to rotate, and the ratchet wheel shaft drives the left torsional spring, the right torsional spring and the middle guide wheel to rotate.
