Driving mechanism for door lock, and door lock

A driving mechanism for a door lock, wherein the driving mechanism comprises:

• a motor;
• a planet gear assembly, comprising a gear ring, a planet gear, and a sun gear;
• wherein the motor is rotatably coupled to the sun gear, the planet gear is rotatably coupled to the sun gear, and the planet gear is also rotatably coupled to the gear ring;
• and
• a gear frame, the gear frame being rotatably coupled to the gear ring, wherein the gear frame has an unmovable state or a rotating state;
• when the gear frame is in the unmovable state, the gear ring is also in the unmovable state, the sun gear is driven by the motor to rotate so as to rotate the planet gear to rotate relative to the gear ring;
• or, when the sun gear is in the unmovable state, and the gear frame is in the rotating state, the gear frame is controlled to rotate, so as to rotate the gear ring, thereby driving the planet gear to rotate relative to the sun gear.

A driving mechanism for a door lock, wherein the driving mechanism comprises:

• a motor;
• a holding frame, the motor being rotatably coupled to the holding frame;
• and
• an universal joint, the universal joint being rotatably coupled to the holding frame;
• wherein the holding frame has a first rotating direction and the universal joint has a second rotating direction, the first rotating direction is intersected with the second rotating direction;
• the universal joint is configured to couple a lock cylinder mechanism;
• the motor controls the holding frame to rotate so as to drive the universal joint to rotate, which in turn drives the lock cylinder mechanism to rotate.
