Abstract

The utility model relates to a hand lighting device, comprising a trigger piece 1, a spring 2, a driving gear 3, a transmission gear 4, a driven gear 5, a fly reel 6, a tensioned spring 7, a microgenerator 8, a bulb 9, a silver bowl 10, a housing 15, etc. The driving gear is separated from the transmission gear if the hands do not wrench a trigger; the driving gear is engaged with the transmission gear if the hands wrench the trigger. The energy provided by hands wrenching the trigger every time causes the rotation speed of the microgenerator to be changed within a range via the engaged rotation, and the transmission of the sector gear, the driving gear, the transmission gear, and the driven gear and the storage/discharge control of the fly wheel, and the generated electricity achieves the goal of illumination. While in use, the battery is not needed to be bought or the hand lighting device is not needed to be charged; the utility model can illuminate as long as the trigger is wrenched, which is simple.

Description

A kind of manual luminaire

The present invention relates to a kind ofly manually drive mechanical rotation, microgenerator is rotated, thereby send the device of electric energy.

The present outdoor lighting device that uses of people, overwhelming majority is that the electric energy with battery or battery throws light on, in case electric energy uses up, can not buy battery or additional electric weight, just can not use; The consumer cost height that uses the battery work to throw light on uses up and loses, and deals with improperly also to pollute the environment; Battery throws light on, and will charge before using, and the consumption electric energy does not have the place of alternating current to use; Battery or battery are put back electric energy decay for a long time even can not be used, the waste electric energy.

At above-mentioned deficiency, invented a kind of manual luminaire.Its objective is without battery or battery provides the electric energy illumination, and with manual microgenerator generating illumination, solves the activity illumination of people in night or hole, ore deposit, both convenient, energy-conservation, save money again, and non-environmental-pollution.

Manually luminaire has comprised trigger piece 1, spring 2, driving gear 3, travelling gear 4, driven gear 5, flywheel 6, extension spring 7, microgenerator 8, bulb 9, silver bowl 10, dead axle 11, shell 15 etc., as shown in the figure: trigger piece 1 fen fan type gear and trigger two parts; One end of spring 2 is packed in the trigger, and the other end is enclosed within on the axle of driving gear 3; The dead axle 11 that trigger piece 1, spring 2 are linked to each other with shell 15 is fixing, rotates around dead axle 11, and an end of extension spring 7 is fixed on the shell 15, the other end is enclosed within on the fan type gear, and trigger is resetted, and is in state to be pulled, the spring hole of extension spring 7 also can resemble and be enclosed within on the dead axle 11 spring 2, rotates around dead axle 11; 3 fens driver pinions of driving gear and gear wheel initiatively, under the restriction of spring 2, driver pinion and fan type gears engaged can be come back rotation on fan type gear, driving gear 3 spool can translation or rotation in the arc groove 12 of shell 15 (among the figure shown in the dotted line); 4 fens drive pinions of travelling gear and transmission gear wheel, transmission gear wheel and driven gear 5 engagements, its axle 13 is fixed by shell 15; Driven gear 5 and flywheel 6 are fastened on the turning cylinder 14 of microgenerator 8, rotate with axle.Manually luminaire is by assembled formations such as above-mentioned equipment and bulb 9, silver bowl 10, electric wire, screw, shells 15.

Manually the operation principle of luminaire is as follows: hand is not pulled trigger, and driving gear 3 is in the right of arc groove 12, and initiatively gear wheel separates with drive pinion, as shown in the figure.When hand is pulled trigger, overcome spring 2, the reaction force of extension spring 7, fan type gear is turned left by the moment that acts on the trigger generation in one's hands, drive initiatively little, gear wheel moves to travelling gear 4, make initiatively gear wheel and drive pinion engagement, the axle of driving gear 3 has moved on to the left side of arc groove 12 and (has pulled in the process at hand, the axle of driving gear 3 is subjected to the effect of the power of spring 2 generations all the time, be in the left side of arc groove 12), if hand continues to pull trigger, fan type gear turns left, and will drive initiatively little, gear wheel rotates, and it is little that the rotation of active gear wheel drives transmission again, the rotation of gear wheel, the rotation of transmission gear wheel drives the rotation of driven gear 5 again, make the turning cylinder 14 of microgenerator 8, flywheel 6 rotates, thereby makes microgenerator send electric energy, supplies with the bulb illumination.After hand discharges external force, fan type gear is subjected to the effect of extension spring 7 pulling force, move right with driving gear 3, the axle of driving gear 3 is subjected to the effect of spring 2 restoring forces simultaneously, initiatively gear wheel hightails drive pinion, driver pinion is backward rotation on fan type gear, the axle of driving gear 3 moves to the right-hand of arc groove 12, driving gear 3 and fan type gear are got back to original separately position, do not pin down, the jam transmission is little, the rotation of the turning cylinder 14 of gear wheel and driven gear 5, flywheel 6, microgenerator, does not consume the energy of passing to the microgenerator operation.Because after flywheel 6 was accelerated rotation, holding had certain energy, can remain to when hand is pulled trigger for the second time, the rotating speed of microgenerator 8 is unlikely to fall too lowly, the influence illumination.Hand is pulled trigger for the second time, the active gear wheel of driving gear 3 drive pinion rapid again and travelling gear 4 meshes, hand is pulled energy that trigger provides once more by fan type gear, initiatively the engagement of little, the gear wheel of little, gear wheel, transmission, driven gear 5 is rotated, promote the rotating speed of microgenerator 8, replenish flywheel 6 used up energy, the rotating speed of microgenerator 8 is changed within the specific limits, and the electricity that sends reaches can illumination purposes.If 8 bringing onto loads of microgenerator (lamp) are inductive loads, can carry out shunt compensation at load two ends parallel connection one electric capacity, improve power factor (PF), power transmission efficiency.

If the required rotating speed of microgenerator 8 normal power generation be n (revolutions per second), the radius of driven gear 5 is r ₅, transmission is little, the radius of gear wheel is r ₄, R ₄, initiatively radius little, gear wheel is r ₃, R ₃, the radius of fan type gear is R ₂, the impetus that finger is pulled trigger apart from the distance of shaft centers of dead axle 11 from being S, R ₃With r ₄The distance (arc length) that engagement back impetus moves for 1 second is L, because fan type gear equates with the central angle of trigger rotation, the central angle initiatively little, that gear wheel turns over equates, the central angle that transmission is little, gear wheel turns over equates, fan type gear, initiatively the tooth pitch on little, gear wheel, the driven gear all equates, pull in the process and be meshing with each other, then the arc length that turns over for 1 second of the tooth on the fan type gear is R ₂* (L/S), this also is the arc length that the tooth on the driver pinion turns over for 1 second, then initiatively the arc length that turns over for 1 second of the tooth on the gear wheel is R ₃* (R ₂* (L/S))/r ₃, this also is the arc length that the tooth on the drive pinion turns over for 1 second, then the arc length that turns over for 1 second of the tooth on the transmission gear wheel is: R ₄* (R ₃* (R ₂* (L/S))/r ₃)/r ₄, this is the arc length that turns over for 1 second of the tooth on the driven gear 5 just, and during the normal operation generating of microgenerator 8, the arc length that the tooth on the driven gear 5 turns over for 1 second is r ₅* 2* π * n wants normal power generation, and both must equate, that is:

R ₄* R ₃* R ₂* L/ (S*r ₄* r ₃)=r ₅When * 2* π * n designs, only need to consider L, S, n, R ₂, r ₃, R ₃, r ₄, R ₄, r ₅Value satisfy following formula and get final product.

Manually luminaire can be widely used in night illumination, the place of particularly rural area short of electricity, nothing electricity, and people walk outside at night, stride terraced ditch, boring the ground hole, use it very convenient.Compare with existing luminaire torch: the one, the torch lighting expense is big, and using torch must often buy battery or often charge could throw light on; Manually luminaire is to change the energy that hand provides into mechanical energy to drive microgenerator generating illumination, need not buy battery or charging, and cost of use is zero.The 2nd, the battery in the torch can not be put the energy limited that lighting hours is provided by battery for a long time; Manually there is not this type of problem in luminaire.The 3rd, the use of torch is simple not as manual luminaire, uses torch to want packed battery or checks whether an interior battery lost efficacy or charge a battery, and can't buy battery or fills the torch that does not power on and can't use; And manually luminaire no matter where, no matter service time length, only need pull trigger just can throw light on, not only simply, but also economical, promote the use of, will be subjected to liking of people.
