Abstract:
A remote-controlled toy car forward/backward steering control mechanism installed in a toy car and coupled to a power drive and controlled by a remote controller to move the toy car forwards/backwards, comprising:a transmission shaft coupled between front wheel system and rear wheel system of the toy car, said transmission shaft comprising a polygonal segment; a first transmission gear wheel revolvably mounted on said transmission shaft at one side of said polygonal segment, said transmission wheel comprising an external gear coupled to the power drive of the toy car, and an internal gear; a second transmission gear wheel revolvably mounted on said transmission shaft at one side of said polygonal segment opposite to said first transmission gear wheel, said second transmission gear wheel comprising an external gear and an internal gear; a first idle gear meshed with the external gear of said transmission wheel; a second idle gear meshed between said first idle gear and the external gear of said second transmission gear wheel; a movable gear mounted on the polygonal segment of said transmission shaft and moved along the polygonal segment of said transmission shaft between a first position where said movable gear is meshed with the internal gear of said transmission wheel for enabling said transmission shaft to be rotated with said first transmission gear wheel clockwise to move the toy car forwards, and a second position where said movable gear is disengaged from the internal gear of said transmission wheel and meshed with the internal gear of said second transmission gear wheel to rotate said transmission shaft counter-clockwise in moving the toy car backwards during rotary motion of said first transmission gear wheel; and a server controlled by the remote controller to move said movable gear between said first position and said second position, said server comprising link means coupled to said movable gear.
