Automatic loading system for vehicles

An automatic loading system for vehicles, comprising:

• an overhead platform comprising two rails;
• a transporting machine disposed on the rails and configured to move on the rails along a first direction, wherein the transporting machine comprises:
• a hoist mechanism;
• a fork assembly disposed on the hoist mechanism, wherein the hoist mechanism is configured to drive the fork assembly to move along a second direction which is perpendicular to the first direction, the fork assembly comprises a plurality of forks which are disposed side by side and separately, and each of the forks comprises at least one conveyer belt;
• an optical scanner configured to perform an optical scanning operation on a truck under the rails when the transporting machine is moving, so as to obtain a plurality of two-dimensional contour data above a load plane of the truck;
• and
• a position sensor configured to sense a location of the transporting machine when the transporting machine is moving;
• and
• a cargo carrying mechanism configured to carry a cargo, wherein the cargo carrying mechanism comprises a conveyer belt platform,
• wherein when the fork assembly is close to the cargo carrying mechanism, the conveyer belts and the conveyer belt platform are configured to transport the cargo to the forks from the conveyer belt platform.
