Abstract
The utility model relates to a portable miniature power generation device. The portable miniature power generation device comprises a spiral spring, a bearing, a magnet support, frame inner side magnet clamping grooves, wire guide grooves, a first top end out-of-band slope surface arc permanent magnet, a second top end out-of-band slope surface arc permanent magnet, a silicon steel plate laminated iron core, a fixed shaft, wire ducts, screws, first coils, second coils, and third coils. The silicon steel plate laminated iron core, the fixed shaft with the wire guide grooves, the first coils, the second coils and the third coils together form a stator. The two ends and the center of the magnet support are disposed on the fixed shaft via the bearing. The inner end of the spiral spring is fixed to the fixed shaft, and the outer end of the spiral spring is fixed to the edge of the magnet support. The frame inner side magnet clamping grooves at two ends of the magnet support enable the first top end out-of-band slope surface arc permanent magnet and the second top end out-of-band slope surface arc permanent magnet to be correspondingly fixed to two sides of the magnet support. The magnet support is screwed by the screws to form a rotor. The two arc permanent magnets identical in geometrical shape are made from different magnetic materials with isotropy. The magnet support is made of aluminium alloy.
