A light-up toy yo-yo, comprising two rotating discs (1), a connecting shaft (2) connecting the two spinning discs (1), a main bearing sleeved on to the connecting shaft (2) and arranged between the two spinning discs (1), and outer rotating bodies (3) respectively covering the outer end face of the two rotating discs (1) and able to rotate relative to said rotating discs (1), a light bulb (4) and a dynamo (5) being arranged in the two rotating discs (1) or in one of said rotating discs (1), the dynamo comprising a stator (51) and a rotor (52), the light bulb (4) being connected to the dynamo (5) by means of a conductive wire, and the rotor (52) being connected to the outer rotating bodies (3) by means of a transmission structure; when the rotating discs (1) rotate relative to the outer rotating bodies (3), the transmission structure drives the rotor (52) to rotate around its own shaft core to generate electric power, the electric power being transferred to the light bulb (4) by means of the conductive wire to illuminate the light bulb (4), such that, when played at night, the yo-yo has an attractive and interesting aesthetic without the need for a battery, thus avoiding the impact on the function of the yo-yo caused by frequent dismantling, and prolonging the service life. |
