1. A forklift-type automated guided vehicle comprising:
a body;
a control circuit unit received in the body; and
a first fork arm and a second fork arm parallel to each other and formed on a front end of the body to forklift cargos;
wherein each of the first fork arm, the second fork arm and a bottom end of the body comprising at least one two-wheel differential driving assembly electrically connected to the control circuit unit, and rotatably connected to the first fork arm, the second fork arm and the body, respectively;
the at least one two-wheel differential driving assembly comprises a left driving wheel and a right driving wheel formed opposite to each other which can be independently driven to realize differential rotation;
wherein the at least one two-wheel differential driving assembly comprises a connecting base, a rotary bearing, a rotating base, a connecting frame, a left driving member, a right driving member, a left driving wheel connected to the left driving member, and a right driving wheel connected to the right driving member;
an upper end of the connecting base connected with the first fork arm, or the second fork arm, or the body, the rotary bearing positioned on a lower end of the connecting base;
an upper portion of the rotating base installed in the rotary bearing, a lower side of the rotating base fixedly connected with the upper end of the connecting base;
both the left driving member and the right driving member respectively installed on two sides of the connecting frame;
wherein the rotating base comprises a rod-shaped rotating shaft arranged on the upper portion thereof, a flange plate arranged at the lower side of the rotating base and coaxially arranged with the rotating shaft, the rotating shaft rotatably installed in the rotary bearing and the flange plate fixed with a top side of the connecting frame; and
the rotating base further comprises a fan-shaped limiting plate circumferentially arranged on an outer wall of the flange plate, and the connecting frame comprises an inductive switch electrically connected to the control circuit unit so that the limiting plate can be rotated in or out of the inductive switch.
