Electric lock and clutch mechanism thereof
An electric lock includes a cover, a clutch rod, a driving module, a clutch member and a handle. The clutch rod is movably connected to a latch. The driving module is disposed on the cover. The driving module includes a driving member abutting against and rotatable relative to the cover, and a motor configured to drive the driving member to rotate. The handle is connected to the clutch member. Wherein, when the motor drives the driving member to rotate relative to the cover along a first rotating direction, the driving member drives the clutch rod to move toward the handle to be engaged with the clutch member for allowing the handle to drive the latch to move through the clutch rod when the handle is rotated.
1. An electric lock, comprising:
a cover;
a clutch rod configured to be movably connected to a latch, a first engaging structure being disposed on one end of the clutch rod;
a driving module disposed on the cover, the driving module comprising:
a driving member abutting against the cover and rotatable relative to the cover; and
a motor configured to drive the driving member to rotate;
a clutch member having a second engaging structure; and
a first handle connected to the clutch member;
wherein when the motor drives the driving member to rotate relative to the cover along a first rotating direction, the driving member drives the clutch rod to move toward the first handle, such that the first engaging structure is engaged with the second engaging structure for allowing the first handle to drive the clutch rod to rotate when the first handle is rotated, so as to move the latch.
2. The electric lock of claim 1 , wherein when the motor drives the driving member to rotate relative to the cover along a second rotating direction, the clutch rod is moved away from the first handle, so as to disengage the first engaging structure from the second engaging structure.
3. The electric lock of claim 1 , wherein the driving member is a gear, the driving module further comprises a transmission member, the transmission member abutting against the driving member and being configured to transmit power generated by the motor to the driving member, and the driving member is movable relative to the transmission member along a rotation axis of the driving member.
4. The electric lock of claim 1 , further comprising a lock core disposed on the first handle, and the lock core being driven by a key, so as to drive the clutch rod to move the latch.
5. The electric lock of claim 1 , further comprising:
an input interface configured to receive an input data; and
a control unit electrically connected to the input interface and the motor and configured to activate the motor when the input data matches a pre-determined data.
6. The electric lock of claim 1 , further comprising an elastic member, the elastic member being disposed between the first engaging structure and the second engaging structure, so as to drive the clutch rod to move away from the first handle.
7. The electric lock of claim 1 , further comprising:
a first base disposed on a first side of a door, wherein the first handle is mounted on the first base in a rotatable manner;
a second base disposed on a second side of the door, wherein the second side is opposite to the first side, and the cover is mounted on the second base; and
a second handle mounted on the second base in a rotatable manner.
8. The electric lock of claim 1 , wherein the driving module further comprises:
a mounting base configured to accommodate the driving member and the motor; and
a resilient member disposed between the driving member and the mounting base, the resilient member being configured to drive the clutch rod to move away from the first handle.
9. The electric lock of claim 1 , wherein the driving module further comprises a connecting member, the connecting member is connected to the clutch rod and abuts against the driving member.
10. The electric lock of claim 1 , wherein the cover has a first cam surface, and the driving member has a second cam surface, the second cam surface abuts against the first cam surface.
11. A clutch mechanism of an electric lock, comprising:
a cover;
a clutch rod configured to be movably connected to a latch and driving the latch to move when the clutch rod is rotated; and
a driving module disposed on the cover, the driving module comprising:
a driving member abutting against the cover and rotatable relative to the cover; and
a motor configured to drive the driving member to rotate;
wherein when the motor drives the driving member to rotate relative to the cover along a first rotating direction, the driving member drives the clutch rod to move relative to the latch along a first direction.
12. The clutch mechanism of claim 11 , wherein when the motor drives the driving member to rotate relative to the cover along a second rotating direction, the clutch rod is moved relative to the latch along a second direction, and the second direction is opposite to the first direction.
13. The clutch mechanism of claim 11 , wherein the driving member is a gear, the driving module further comprises a transmission member, the transmission member abutting against the driving member and being configured to transmit power generated by the motor to the driving member, and the driving member is movable relative to the transmission member along a rotation axis of the driving member.
14. The clutch mechanism of claim 11 , wherein the driving module further comprises:
a mounting base configured to accommodate the driving member and the motor; and
a resilient member disposed between the driving member and the mounting base, the resilient member being configured to drive the clutch rod to move relative to the latch along the second direction.
15. The clutch mechanism of claim 11 , wherein the driving module further comprises a connecting member, the connecting member is connected to the clutch rod and abuts against the driving member.
16. The clutch mechanism of claim 11 , wherein the cover has a first cam surface, and the driving member has a second cam surface, the second cam surface abuts against the first cam surface.
