| 20110056759 | MOVING BASE FOR ROBOTIC VACUUM CLEANER - A moving base for robotic vacuum cleaner includes a base; a motor mounted in a motor chamber on the base to alternatively drive a drive shaft thereof to rotate clockwise or counterclockwise: a primary wheel fixed to and rotating along with the drive shaft of the motor; a clutch assembly connected to the primary wheel; an axle connected at an end to the clutch assembly, so as to be driven by tile primary wheel to rotate when the drive shaft of the motor rotates clockwise, or to disengage from the driving by the primary wheel when the drive shaft of the motor rotates counterclockwise: and a secondary wheel connected to another end of the axle to rotate along with the axle. Since only one motor is needed to control a moving direction thereof, the robotic vacuum cleaner can have effectively reduced manufacturing cost and overall volume. | 03-10-2011 |
