Movable conveyors for moving a four-wheel vehicle

An automatic parking system including at least one conveyor for moving a four-wheel vehicle, the at least one conveyor comprising:

• a frame provided with moveable arms that are rotatable between a position in which the arms allow moving the frame under the vehicle, and a position in which the moveable arms come into contact with treads of wheels of the vehicle;
• fixed arms laterally projecting from a portion of the frame in front of the moveable arms;
• the frame being telescopic and comprises two segments each carrying a pair of the arms, at least one of the pairs of arms being articulated to allow movement between an extended position perpendicular to a longitudinal axis of the frame with an extension at least equal to a vehicle track, and a folded-up position to occupy a width that is lower than a distance between inner sidewalls of the vehicle's wheels;
• the segments being movable between a position in which the moveable arms are not in contact with the wheels, and a position in which each moveable arm comes into contact with the tread of the wheels, to raise or lower the vehicle;
• at least one of the segments including a structure to which at least one of the pairs of arms are coupled, and a lifting mechanism configured to raise or lower the structure and thereby raise or lower the vehicle;
• ground-contacting rollers, casters or rails located below the frame inboard of all of the arms when the arms are in wheel-engaging positions;
• a front block coupled to the frame, the front block including a detector located at a vehicle bumper height;
• the front block enclosing drive wheels configured to roll on ground, an electric motor configured to control rotation of the drive wheels, a steering mechanism configured to steer the drive wheels, and a computer located in the front block;
• a first actuator configured to pivot a first pair of the moveable arms between the extended position and the folded-up position;
• a second actuator configured to pivot a second pair of the moveable arms between the extended position and the folded-up position;
• and
• a third actuator configured to move the second segment of the frame relative to the first segment of the frame along the longitudinal axis of the frame.
