Abstract:
1. A toy car wheel with an adjustable center of gravity, comprising: at least one spoke; at least one spiral channel defined in each of the at least one spoke; and at least one spherical body disposed in each of the at least one spiral channel; wherein when the toy car moves at a normal speed, the at least one spherical body moves to a middle portion of a corresponding one of the at least one spiral channel in one of the at least one spoke, when the toy car decelerates, a momentum of the toy car decreases, the at least one spherical body descends in the corresponding spiral channel and the at least one spherical body moves to one end of the corresponding spiral channel, a center of gravity of the at least one spherical body moves downwards and the center of gravity of the toy car wheel descends.
