TUBULAR MOTOR ARRANGEMENT ADAPTABLE TO SHADE WINDING ROLLERS OF VARIOUS LENGTH OR DIAMETER

摘要

A motorized roller shade includes a shade tube, including an outer surface upon which a shade is attached, an inner surface defining an inner cavity and two end portions, and a motor having an output shaft coupled to a support shaft such that the output shaft and the support shaft do not rotate when the support shaft is attached to a mounting bracket. The motorized roller shade further includes a counterbalancing unit configured to provide a counterbalancing force to the shade, a power supply unit, electrically coupled to the motor, configured to supply power to the motor, and an adaption component including at least one of a length adaptation component and a diameter adaptation component arranged within the shade tube and configured to adapt at least one of the motor and the counterbalancing unit to be used with a larger shade tube.
