Abstract: A motorized shade assembly includes a housing having a compartment defined by an inner periphery. A driving device is mounted in the compartment and includes a shaft. An operating rod is coupled with the shaft to turn therewith. A shade is coupled to the operative rod to move therewith. A vibration absorbing member is made of a buffering, flexible material and includes a central hole having an inner periphery clamping the driving device. The vibration absorbing member further includes an outer periphery pressing against the inner periphery of the housing. The driving device is operable to move the operating rod and the shade. The vibration absorbing member reduces vibration and noise generated during operation of the driving device.

Abstract: A displacement-preventing device includes a control device electrically connected to an AC power source. The control device includes an upward movement contact, a downward movement contact, and a common contact. A power circuit is electrically connected to the common contact and converts the AC power source into a DC power source. A positing circuit is electrically connected to the control device, the power circuit, and the motor. The control device is operable to control rotation of the motor in either of two opposite directions for moving the coilable shade in the coiling direction or the uncoiling direction. The control device stops the motor when no power is input to the motor, and the positioning circuit causes a positive terminal of the motor to be in electrical connection with a negative terminal of the motor.
