Abstract: A linkage mechanism includes: a base member; a first link rotatably connected to the base member, the first link defining a first arc-shaped guide groove centered on a pivot axis about which the first link rotates relative to the base member; a second link rotatably connected to the first link; a connecting member rotatably connected to the base member and the second link; an actuating mechanism including a linear actuator and a transmission member that is driven by the linear actuator, the transmission member having a first end rotatably connected to the output shaft, and a second end slidably received in the first arc-shaped guide groove. When the linear actuator drives the connecting member to extend and move, the second end of the transmission member abuts against one end of the first arc-shaped guide groove, which drives the first link to rotate relative to the base member.

Abstract: An energy storing assistive mechanism includes a barrel having a first pivot end and an open end, a rod having a first end that passes through the open end and is received in the barrel, an elastic structure including two ends that abut against the first end of the rod and the first pivot end, a uni-directional gear rack having a second pivot end away from the barrel, and a locking mechanism fixed to the rod, the locking mechanism comprising a locking member and an actuator assembly that is to drive the locking member to move between a first position where the locking member is engaged with the gear rack, and a second position where the locking member is disengaged from the gear rack.
