The specific embodiment

As accompanying drawing 1～shown in Figure 5, the lock core that the utility model includes lock deckle board, charging circuit, the micromotor that is connected with the charging circuit output and driven by micromotor, also include a flywheel self-powering apparatus, this device is made up of tooth bar 10, driving gear 20, movable switch block 30, flywheel 40 and microgenerator 50, the driving gear 20 that is set on the fixed rotating shaft 21 forms coaxial pinion 22 and gear wheel 23, and the pinion 22 on the gear teeth of tooth bar 10 and the driving gear 20 is meshing with each other; Movable switch block 30 is made up of two

lever arms

32 and 33 that rhombus flap 31 and symmetry are hinged on these two ends, rhombus flap 31 below, center on rhombus flap 31 forms a driven pinion 34, and the gear wheel 22 on this driven pinion 34 and the driving gear 20 is meshing with each other; Offer knuckle-tooth shape cavity 41 with the upper surface of the microgenerator 50 coaxial flywheels that are connected 40, the circumference of this knuckle-tooth shape cavity 41 is by some

The shape tooth colludes 411 and interconnects and form, two lever arms 32 of

movable flap

30 and 33 end form with this tooth and collude

corresponding tooth

321 and 331 of pushing away of 411 shapes size, movable flap 30 and flywheel 40 are set in the same rotating shaft 60 by centre bore separately, and movable flap 30 is contained in the knuckle-tooth shape cavity 41 on the flywheel 40 and the minimum diameters of knuckle-tooth shape cavity 41 are a bit larger tham two

lever arms

32 and 33 maximal sides that fold after putting in place of rhombus flap 31; Micromotor is connected with charging circuit.The bottom surface of described flywheel 40 has cavity 42, the intracardiac circular magnetic patch 43 that is fixed with in this cavity 42; Microgenerator 50 includes coil 51 and the positive and

negative electrode
