A combined type toy top separated through induction control, includes a main top, an auxiliary top and an elastic part. When the combined type toy top is in a first state, the main top is limited and fixed by the auxiliary top, above the auxiliary top, and meanwhile the main top compresses the elastic part so that the elastic part is compressed. The combined type toy top is characterized in that a sensing mechanism is arranged in the auxiliary top. The sensing mechanism can controllably relieve limiting fixation of the main top from the auxiliary top under a second state through induction control. The main top pops up under an elasticity action of the elastic part, and, accordingly, the main top and the auxiliary top rotate independently.

A gravity-assisted rotational mechanism and a generator device cooperating therewith. The gravity-assisted rotational mechanism includes multiple concentric rotational members having different sizes and rotatable about the same rotational center, several link members having equal weights for driving the same, and at least one connection member for pivotally connecting the rotational members with the link members. The rotational members can symmetrically push/pull each other. The link members and connection member are respectively mounted on interference sections of at least some of the rotational members to absorb gravitational energy. The energy of the link members is transmitted via the interference sections to the rotational members to form a cycle of energy storage and transmission. The generator device serves to convert the gravitational energy and minimize the rotational inertia loss and increase yield rate of electrical energy.
