ABSTRACT:
A motor-driven screen roller assembly is provided that consists of each of two motor-driven screen rollers controlled by a FORWARD/STOP/BACKWARD control switch through a selector switch. Each motor-driven screen roller includes a mounting plate fixed to the ceiling inside an automobile, two reversible DC motors fastened on opposing ends of the mounting plate, at the bottom. A roller is coupled between the reversible DC motors, and a screen having one end fixed to the roller and an opposing end thereof being coupled to a slat. The FORWARD/STOP/BACKWARD control switch and the selector switch are connected in series between the reversible DC motors of the motor-driven screen rollers and the battery power supply circuit of the automobile. The FORWARD/STOP/BACKWARD control switch operates in cooperation with the selector switch to selectively control the operation of the DC motors of the first motor-driven screen roller or the second motor-driven screen roller.
