This invention discloses a dual-mode (active and passive) dual-arm upper limb assistive exoskeleton. In the left or right arm assistive exoskeleton of this invention, the lower end of the mounting plate forms a rotating joint with a fixed base on a support vest via a waist support rod, and the upper end forms a rotating joint with a connecting piece via a back support rod. One end of the shoulder support block is fixed to the arm support rod, and the other end is connected to the active slider via a steel wire rope. The middle part forms a rotating joint with the connecting piece and is driven by a motor. The active and passive sliders, both forming sliding joints with the mounting plate, are connected to the mounting plate via tension and compression springs, respectively. A roller at one end of a V-shaped rotating component is located directly above a protrusion on the active slider, and the roller at the other end forms a rolling friction pair with a sliding inclined plate on the mounting plate. The middle part is hinged to the passive slider and connected via a torsion spring. This invention achieves arm assistance through both active motor assistance and passive spring-energy-storage assistance.
