The invention relates to the technical field of mechanical transmission mechanisms, and discloses a passive automatic translation mechanism. The passive automatic translation mechanism solves the technical problem that an existing translation elevator needs a power source for driving and comprises a straight rack, a gear assembly, a pressure shaft and a pressed plate. the gear assembly comprises an outer ring gear, an inner ring gear, a central gear and a planetary gear set, the outer ring gear and the inner ring gear are mutually fixed, the central gear, the outer ring gear and the inner ring gear are coaxially arranged, and the planetary gear set is installed between the inner ring gear and the central gear in a meshed manner; the planetary gear set comprises a first planetary gear, a second planetary gear, a third planetary gear and a fourth planetary gear, and the first planetary gear serves as a driving gear; the top end of the pressure shaft is fixed to the pressed plate, and the bottom end of the pressure shaft is fixed to a rotating shaft of the first planetary gear; and the straight rack is meshed with the outer ring gear. According to the technical scheme, the novel translation mechanism is designed, so that the purpose of passive driving is achieved by utilizing pressure borne by the pressed plate to do work.
