Description
What the utility model manual power generating type flashlight related to is a kind of flashlight with hand power facility.
Flashlight adopts dry cell or battery to make the illumination electric energy usually at present, if need use to such an extent that change expense substantial contribution is bought battery for a long time.Battery is charging often, also must change the expense power supply, and the battery cost is higher also has to change certain service life, and the battery that changes can cause secondary environmental pollution.
The purpose of this utility model is to exist weak point that a kind of manual power generating type flashlight is provided at present flashlight, has the hand gear transmission mechanism, and microgenerator, but electricity generated manually illumination are easy to use, use cost is low, non-environmental-pollution.
The manual power generating type flashlight takes following mode to realize: the manual power generating type flashlight structure includes the torch housing, handle, spring, manual tooth bar, duplicate gear, some groups of change-speed gearings, flywheel, the flywheel travelling gear, microgenerator, the torch lamp holder, lighting bulb, spotlight bowl, lampshade, lead, voltage-stabiliser tube, in the torch body shell duplicate gear is housed, many group change-speed gearings (accelerating gear), flywheel, the flywheel travelling gear, respectively by the gear shaft device on torch housing internal gear support, torch housing posterior means has DC micromotor, the DC micromotor shaft end is equipped with the generator shaft end gear, is meshed with change-speed gearing.Manually tooth bar is meshed with duplicate gear, and duplicate gear drives many group change-speed gearing (accelerating gear) transmission generator shaft end gears.Device is equipped with the flywheel travelling gear on the flywheel power transmission shaft on the gear stand, flywheel gear is on flywheel shaft, and flywheel shaft is fixed on the gear stand.The flywheel travelling gear of change-speed gearing transmission device on the flywheel power transmission shaft be the transmission flywheel again.Double crosslinking gear shaft bearings at both ends device is in the gear stand chute, and duplicate gear can upper and lowerly slide.The torch lamp holder is equipped with in torch housing front portion, in the torch lamp holder lighting bulb is housed, spotlight bowl, and torch lamp holder front end has the torch lampshade that glass cover is housed.The DC micromotor power output end is equipped with Zener diode, is connected with lighting bulb by lead.
Hand is pressed fixed handle and is driven tooth bar transmission duplicate gear during the work of manual power generating type flashlight, duplicate gear drives many group change-speed gearings (accelerating gear), transmission device is at the generator shaft end gear of generator shaft end, the transmission generator rotor shaft rotates generating, produce DC current by the required voltage of voltage-stabiliser tube steady illumination bulb, make illuminating lamp keep certain lighting voltage and brightness of illumination.Change-speed gearing drove the flywheel rotation by transition gear when travelling gear transmission generator rotor shafts rotated, when handle loosens because the stage clip elastic reaction, make the tooth bar rising drive duplicate gear and leave speed change transition gear (because of the duplicate gear bearing block is assemblied in the bracket chute, duplicate gear and assembling gear axle can rise with the stage clip resilient force).Flywheel is rotated further generating because inertia motion is rotated further drive generator shaft end gear simultaneously.Therefore, constantly press release handle tooth bar successively transmission duplicate gear, change-speed gearing, flywheel, driving the minisize dc electric generator generating provides lighting bulb enough power supplys.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is a manual power generating type flashlight structure schematic diagram.
With reference to accompanying drawing manual power generating type flashlight structure have manual tooth bar 1 is housed in torch housing 18, the torch housing 18, manually tooth bar 1 top is connected with handle 16, tooth bar lower device that stage clip 23, compression spring sleeve are contained on the guide pillar 24, multiple sets of teeth wheel support 21 is housed in the torch housing 18, duplicate gear 2 is housed on the gear stand, (accelerating gear) 3,4,5,6 of organizing change-speed gearing more, flywheel 15, flywheel travelling gear 8,9,10 are assemblied in respectively on the torch housing internal gear support.Torch housing 18 posterior means have DC micromotor 19, and the DC micromotor shaft end is equipped with generator shaft end gear 7, are meshed with change-speed gearing 6.Duplicate gear 2 is combined by pinion and gear wheel, and double crosslinking gear shaft bearings at both ends device is in gear stand chute 20, and duplicate gear 2 can slide up and down.Manually tooth bar 1 is meshed with duplicate gear 2, the gear wheel of duplicate gear 2 and change-speed gearing 3 engagements, and gear wheel 4 is fixed on the same axle with change-speed gearing 3, and gear wheel 4 is meshed with change speed pinion 5, and gear wheel 6 is fixed on the same axle with little tooth.Duplicate gear 2 drives many group change-speed gearings (accelerating gear) 3,4,5,6 and rotates, and transmission generator shaft end gear 7 drives the generator amature quick rotation.Change-speed gearing 6 is by the flywheel travelling gear 8,9 of device on flywheel power transmission shaft 17 simultaneously, and transmission is contained in the flywheel travelling gear 10 on the flywheel shaft, drives flywheel 15 turns.Torch lamp holder 14 is equipped with in torch housing 18 front portions, and lighting bulb 13 is housed in the torch lamp holder, and lighting bulb is equipped with spotlight bowl 12 outward, and torch lamp holder front end has torch lampshade 11, and glass cover is housed.DC micromotor 19 power output ends are equipped with Zener diode DW1, DW2, are connected with lighting bulb 13 by lead 22, supply with lighting bulb burning voltage power supply.
