ABSTRACT:
An electrical toy baby cart includes two handles. Two front frames and two rear frames are respectively and pivotally connected to the bottoms of the handles. A front wheel holder is fastened to the bottoms of the front frames and supported on two front wheels, and a rear wheel axle is fastened to the bottoms of the rear frames and supported on two rear wheels. A battery box arranged between said front and rear frames. A transmission gear box, a control box electrically connected to the battery box and having a motor controlled to drive the transmission gear box, and two transmission wheels driven by the transmission gear box to move the electrical toy baby cart are provided within the front wheel holder. When the handles are pressed downward and then turned downward toward the front frames, the top projecting block at the top end of each rear frame is moved away from the top projecting block at the top end of either front frame for permitting the electrical toy baby cart to be collapsed.
