Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

See also Fig. 1～Figure 11, the utility model comprises housing 1, microgenerator 2, hand-pulling type power generating apparatus, transmission device, and hand-pulling type power generating apparatus, transmission device all place in the housing 1.Microgenerator 2 connects accessory power outlet by change-over circuit.

The hand-pulling type power generating apparatus comprises backguy 31, reel 32, clockwork spring 33, axle 34, copper bush 35, along axle 34 copper bush 35, clockwork spring 33, reel 32 be installed successively radially, axle 34 and microgenerator input shaft 21 are arranged in parallel, and axle 34 and copper bush 35 are fixedly connected on the housing 1.Reel 32 is formed by two upper and lower end cap 323,324 fits that have barrel respectively, one end of clockwork spring 33 is stuck in the bar-shaped trough 351 of copper bush 35, the other end is stuck in the draw-in groove 321 of lower end cap 324 inwalls of reel 32, backguy 31 and extends outside the housing 1 on the outer wall of the upper end cap 323 of reel 32.

Transmission device comprises a pair ofly scratches tooth 41, ratchet 42 and is connected gear 43 on the microgenerator input shaft 21, coaxial with the ratchet 42 and the reel 32 of gear 43 engagements, end face has coaxial ratchet shape shrinkage pool 421, a pair of tooth 41 centers of scratching are arranged symmetrically in the ratchet shape shrinkage pool 421, cylindrical protrusions 411 movable sheaths of scratching tooth 41 blunt end are connected in the cylindrical shrinkage pool 322 of reel 32 bottom surfaces, and the tip end can prop up the ratchet of ratchet shape shrinkage pool 421.

The end of backguy 31 outside housing 1 passes the hollow hole of cable guide 51, the hollow hole of backguy cover 52 is fixedly connected on the backguy cover 52, and stay thimble 53 is trip rings, and two opening ends are stuck in the both sides shrinkage pool of backguy cover 52.

See also Figure 12 and Figure 13, the concrete working procedure of this hand-pulling type self power generation charger is as follows: under the nature, clockwork spring 33 relaxes, backguy 31 twists on the reel 32, when generating electricity if desired, just spur stay thimble 53, pull out backguy 31, backguy 31 drives reel 32 rotations, reel 32 then drives clockwork spring 33, clockwork spring 33 is tightened, and the tip end of scratching tooth 41 this moment can prop up the ratchet on the ratchet shape shrinkage pool 421 that swashs wheel 42, and the result is exactly that reel 32 drives ratchets 42 rotations, ratchet 42 is because mesh with the gear 43 that is installed on the microgenerator input shaft 21, can rotate by driven gear 43 with that, thereby make microgenerator 2 work, produce electric energy; When backguy 31 is pulled to the end, loosen backguy 31, clockwork spring 33 is because the elastic force effect, can drive reel 32 counterrotatings fast, thereby rolling backguy 31, scratch tooth 41 simultaneously and can slip over ratchet on the ratchet shape shrinkage pool 421 of ratchet 42, make the tip end of scratching tooth 41 can not prop up ratchet, so also just can not drive ratchet 42 rotations.So repeat to spur backguy 31, just reached the purpose that makes microgenerator 2 generatings.
