COMPACT POWER ACTUATOR FOR WINDOW SHADES |
摘要 |
A window shade having a power actuation system. The window shade includes a fixed member; a rotatable member that is rotatable relative to the fixed member; a reversible motor mounted to the fixed member, wherein the reversible motor includes a mechanism for driving the rotatable member such that rotation of the reversible motor in a first direction deploys a shade material and rotation of the reversible motor in a second direction stows the shade material; and a control circuit coupled to a set of motor leads of the reversible motor, wherein the control circuit switches the reversible motor among at least three operational states, including: a hold state in which the motor leads are shorted to resist rotation, a deploy state in which the motor leads are connected to a power source to deploy the shade material, and a stow state in which the motor leads are connected in reverse to the power source to stow the shade material. |

1. An actuation system for a window shade comprising:
a reversible motor mounted to a fixed member of the window shade, wherein the reversible motor includes a mechanism for driving a rotatable member of the window shade such that rotation of the reversible motor in a first direction deploys a shade material and rotation of the reversible motor in a second direction stows the shade material; and a control circuit coupled to a set of motor leads of the reversible motor, wherein the control circuit switches the reversible motor among at least three operational states, including: a hold state in which the motor leads are shorted to resist rotation, a deploy state in which the motor leads are connected to a power source to deploy the shade material, and a stow state in which the motor leads are connected in reverse to the power source to stow the shade material. |
