Abstract
A wall-climbing toy vehicle includes a body having a car frame structure and a base member. The car frame structure is coupled to the base member. The base member includes a horizontal part and a vertical part. The horizontal part defines a curved surface negative pressure cavity. The horizontal part includes air inlet ports and shunt grooves. The vertical part includes at least one drive mechanism installation port and a plurality of wheel installation ports. Further an air suction assembly is coupled along the air inlet ports on the horizontal part. Furthermore, at least one drive mechanism assembly is coupled to the at least one drive mechanism installation port on the vertical part. The air suction assembly and the at least one drive mechanism assembly are adapted to be driven via a power supply arrangement to enable the wall-climbing toy vehicle to drive against the vertical wall.
