<p>An automatic electric power generating device for wheels includes a wheel hub (11) and a housing (16). The wheel hub (11) is provided with a first magnetic pole set (1) and a second magnetic electric element (163). The first magnetic pole set (1) has a spool (12), and left and right magnetic poles (13,14). The spool (12) is winded with a coil (121) having a guiding end thereof connected to an illuminating element (117) installed at the wheel hub (11). The housing (16) is provided with a first magnetic element (263) and a second magnetic pole set (2). The second magnetic pole set (2) has a spool (22), and left and right magnetic poles (23,24). The spool (22) is winded with a coil (221) having a guiding end thereof connected to a lighting device (118). Through rotations of the wheel, induction is generated between the driven and rotating magnetic pole sets and the magnetic elements. <IMAGE></p> |
