Claim:
A flexible and rigid bi-status coupler and its application device wherein, the bi-status coupler is comprised of a generation effect coupler provided with flexible coupling function incorporated with a one-way transmission including: an input side ( 401 ): containing a rotary kinetic energy transmission structure to be coupled to one side of a one-way transmission ( 404 ) and also coupled to the active rotary part ( 4031 ) of a generation effect coupler; an output side ( 402 ): containing a rotary kinetic energy transmission structure to be coupled to the passive rotary part ( 4032 ) of the generation effect coupler, and then couple to the other side of the one-way transmission ( 404 ); the generation effect coupler ( 403 ): comprised of the active rotary part ( 4031 ) of the generation effect coupler related to a magnetic field comprised of a permanent magnet or a winding excited by current; and an armature engaging in relative rotation serves as the passive rotary part ( 4032 ) of the generation effect coupler; the active rotary part ( 4031 ) of the generation effect coupler is coupled to the input side ( 401 ) and the passive rotary part ( 4032 ) of the generation effect coupler is coupled to the output side ( 402 ), both control the generation power of the generation effect coupler ( 403 ) transmitted to a load ( 406 ) by means of a generation load controller ( 405 ); consequently, when the active rotary part ( 4031 ) of the generation effect coupler is rotating as driven by the input side ( 401 ), a relative revolution difference is created that varies depending on the changed load to execute flexible transmission of non-rigid transmission to drive the passive rotary part ( 4032 ) of the generation effect coupler to drive the output side ( 402 ); the coupling relation respectively between the active rotary part ( 4031 ) of the generation effect coupler and the input side ( 401 ) as well as between the passive rotary part ( 4032 ) of the generation effect coupler and the output side ( 402 ) is configured to be exchanged such that the active rotary part ( 4031 ) of the generation effect coupler is coupled to the output side ( 402 ), and the passive rotary part ( 4032 ) of the generation effect coupler is coupled to the input side ( 401 ); the one-way transmission ( 404 ): comprised of a conventional one-way clutch, or a transmission that engages in one-way rotary transmission and idling in the other way, having its one end coupled to the input side ( 401 ) and the other side, to the passive rotary part ( 4032 ) of the generation effect coupler; and the generation load controller ( 405 ): comprised of a dynamo-electric or solid-state electronic circuit to control the generation power of the generation effect coupler ( 403 ); a load ( 406 ): related to a resistance or other external load to serve as the generation load for the generation effect coupler ( 403 ).
