Abstract
The present disclosure provides a driving mechanism for a door lock and a door lock. The driving mechanism includes a motor, a planet gear assembly and a holding frame. The planet gear assembly includes a gear ring, a planet gear and a sun gear. The motor is rotatably coupled to the sun gear. The gear ring defines a receiving space. The planet gear and part of the sun gear are received in the receiving space. The planet gear is rotatably coupled between the sun gear and the gear ring. The holding frame is located on one side of the planet gear assembly. The planet gear is coupled to the holding frame. When the gear ring is in an unmovable state, the sun gear is rotated by the motor. When the sun gear is in an unmovable state, the gear ring is controlled to rotate.
Claims17
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 further rotatably coupled to the gear ring;
- and
- a holding frame being coupled to the planet gear;
- when the gear ring is in an unmovable state, the sun gear is rotated by the motor so as to rotate the planet gear relative to the gear ring, thereby driving the holding frame;
- or, when the sun gear is in an unmovable state, the gear ring is controlled to rotate so as to rotate the planet gear relative to the sun gear, thereby driving the holding frame to rotate;
- wherein the driving mechanism further comprises a gear frame;
- the gear frame is rotatably coupled to one side of the gear ring, the gear frame has an unmovable state or a rotating state;
- wherein the motor is located on a first side of the planet gear assembly;
- the gear frame is located on a second side of the planet gear assembly;
- the first side is opposite to the second side.
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;
- wherein the motor is located on a first side of the planet gear assembly, and the gear frame is located on a second side of the planet gear assembly, the first side is opposite to the second side.
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.
