Abstract

A control system for a shutter is disclosed. The shutter includes a force-bearing mechanism and a plurality of slats. The control system includes a power source, a driving device connected to the power source to output a first driving force, which drives the force-bearing mechanism to rotate the slats, and a clutch mechanism, which includes an input member and an output member which are drivable to be connected together for synchronous operation, or to be mutually disconnected for independent operation. When the driving device outputs the first driving force, the input member is engaged with the output member, and the first driving force can be transmitted to the force-bearing mechanism through the clutch mechanism to rotate the slats. When the driving device stops, the input member is disengaged from the output member, and the slats and the force-bearing mechanism are rotatable relative to the driving device.

First claim

What is claimed is:

1. A control system for a shutter, wherein the shutter includes a force-bearing mechanism and a plurality of slats; the control system comprising:
a power source;
a driving device, which is connected to the power source, wherein the driving device driven by the power source to output a first driving force, wherein the first driving force is used to drive the force-bearing mechanism to rotate the slats; and
a clutch mechanism, which is adapted to be driven to optionally allow the driving device to drive the force-bearing mechanism, wherein the clutch mechanism comprises an input member and an output member; the input member and the output member are able to be driven to be connected to each other to be operated synchronously, and the input member and the output member are also able to be driven to be disconnected from each other to be operated independently;
when the driving device outputs the first driving force, and the input member of the clutch mechanism is engaged with the output member, the first driving force is transmitted to the force-bearing mechanism through the clutch mechanism, whereby to drive the slats to rotate;
when the driving device stops outputting the first driving force, the input member of the clutch mechanism is disengaged from the output member, and the slats and the force-bearing mechanism are able to rotate independently relative to the driving device.

2. The control system of claim 1 , wherein the input member of the clutch mechanism is driven by the first driving force of the driving device to be engaged with the output member.

3. The control system of claim 2 , wherein the clutch mechanism further comprises a movable arm; the input member comprises a central member, and the output member comprises a friction base; the central member is located in the friction base, and the movable arm is between the central member and the friction base; the movable arm is operated with the central member, the central member is operated with the driving device, and the friction base is operated with the force-bearing mechanism; when the central member is driven by the first driving force, the movable arm is moved by a movement of the central member toward an inner surface of the friction base; when the movable arm is moved to tightly abut against an inner surface of the friction base, the input member and the output member are driven correspondingly with each other, whereby the force-bearing mechanism is drivable by the first driving force.

4. The control system of claim 3 , wherein the clutch mechanism further comprises a tension spring, of which two ends are respectively connected to the movable arm and the central member; the tension spring constantly applies a pulling force to the movable arm, so that the movable arm is able to be pulled away from the inner surface of the friction base.

5. The control system of claim 2 , wherein the driving device is further driven by the power source to output a second driving force; a rotation direction of the second driving force is opposite to a rotation direction of the first driving force; when the driving device outputs the second driving force, the first driving force stops, and the input member of the clutch mechanism is driven by the second driving force to disconnect from the output member.

6. The control system of claim 5 , wherein the clutch mechanism further comprises a swing arm and at least one transmission gear, the awing arm has a pivoting axle, so that the swing arm is able to pivot about the pivoting axle; the input member comprises a central gear, and the output member comprises an engaging gear; the central gear and the pivoting axle are coaxially positioned; the at least one transmission gear is provided at the swing arm, and the transmission gear meshes with the central gear; the central gear and the driving device are operated with each other; the engaging gear and the force-bearing mechanism are operated with each other;
when the first driving force drives the central gear to rotate, the central gear drives the at least one transmission gear to rotate, and a rotation of the central gear also drives the swing arm to pivot in a first pivoting direction till the at least one transmission gear meshes with the engaging gear, whereby to transmit the first driving force to the force-bearing mechanism;
when the at least one transmission gear meshes with the engaging gear, and the second driving force drives the central gear and the at least one transmission gear to rotate, the swing arm is able to pivot in a second pivoting direction opposite to the first pivoting direction till the at least one transmission gear is disengaged from the engaging gear, so that the force-bearing mechanism is able to be operated independently relative to the driving device.

7. The control system of claim 6 , wherein the swing arm includes a first end and a second end opposite to the first end; the pivoting axle is positioned at the first end; the second end further includes a positioning member, and an axis of the engaging gear passes through the positioning member; when the swing arm is pivoted by the central gear, the positioning member of the engaging gear confines the axis of the engaging gear, whereby to limit a pivoting range of the swing arm.

8. The control system of claim 5 , wherein the clutch mechanism further comprises an inner base and a ball; the input member comprises a rotating body, and the output member comprises an outer base; the rotating body, the inner base and the outer base are coaxially positioned from inside to outside in sequence, the rotating body and the driving device are operated with each other, and the outer base and the force-bearing mechanism are operated with each other; the inner base has an opening which is larger than the ball; the ball is correspondingly positioned in the opening, and is able to move along the opening inward and outward relative to the inner base, whereby to optionally connect the rotating body and the inner base, or to optionally connect the inner base and the outer base; when the ball connects the rotating body and the inner base, the input member and the output member are no longer linked with each other, so that the force-bearing mechanism is able to rotate independently relative to the driving device; when the ball connects the inner base and the outer base, the input member and the outer member are able to rotate synchronously in the same direction, so that the first driving force is able to drive the force-bearing mechanism to rotate.

9. The control system of claim 8 , wherein the outer base has an annular inner surface facing the inner base, and the inner surface has a rib protruded therefrom toward the inner base, the rotating body has at least one groove corresponding to the opening of the inner base; when the rotating body is driven by the first driving force till the groove does not face the opening, the ball protrudes from the opening to abut against the rib, so that the inner base drives the outer base to operate simultaneously; when the rotating body is driven by the second driving force till the groove faces the opening, the ball is at a space formed between the groove and the opening, and the ball is not protruded from the opening, and no longer contacts the outer base, so that the inner base is able to rotate synchronously with the rotating body.

10. The control system of claim 8 , wherein the rotating body has an outer surface, and the outer surface has a bump protruded therefrom; the inner base has an inner surface facing the outer surface of the rotating body, and the inner surface has a blocker protruded therefrom; the blocker corresponds to the bump; when the rotating body is rotated by the
