Description

Flashlight with electric generation by itself

The utility model relates to a kind of flashlight, particularly a kind of flashlight with electric generation by itself without external power source.

Existing flashlight generally all adopts dry cell or rechargeable battery to throw light on as power supply, and no external power source can't use.After the dry cell electric weight was used up, the untimely perishable damage torch of the battery body that takes out from the torch body influenced the normal use of flashlight.

The purpose of this utility model provides a kind of flashlight with electric generation by itself, and its volume is little, be easy to carry, simple to operate, easy to use, energy-conservation, laborsaving, environment is not caused any pollution.

The purpose of this utility model is achieved in that this device comprises protecgulum, bonnet, lampshade, lamp socket, the bulb on cylindrical shell and the assembling cylindrical shell, wherein the coil output of permanent magnet TRT and lamp socket both positive and negative polarity join, its rotating shaft end tooth that installs permanent magnet is taken turns by the gear train that has escapement and the driving gear of going barrel end and is joined, and the driving shaft that is fixed with the clockwork spring volume utilizes one-way wheel and connector to be assembled on the movable bonnet.

Because the utility model adopts the permanent magnet TRT to replace dry cell or rechargeable battery, so be particularly suitable for field work or areas without electricity local lighting usefulness.And the rotating shaft rotational power of TRT permanent magnet is to be provided by the clockwork spring on the driving shaft by the gear train of being with escapement.That is to say the clockwork spring that utilizes bonnet to screw to be packed on the driving shaft, the release of clockwork spring self elastic force makes drive shaft turns, installs the rotating shaft rotation of permanent magnet by gear set drive, and meanwhile coil produces electric current, makes the shinny illumination of bulb.Because gear train adopts the mechanical transmission structure form of clock, so the cylindrical shell volume is little, is easy to carry.When needing illumination,, can make bulb shinny as long as the rotation bonnet makes clockwork spring energetically, thus simple to operate, laborsaving, easy to use, influence because of not being subjected to external power source, thus energy-conservation, can not produce the environmental pollution that dry cell causes.

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

Fig. 1 is a kind of concrete structure schematic diagram of the utility model.

Fig. 2 is the cutaway view of Fig. 1 along the A-A line.

Fig. 3 is the drive mechanism schematic diagram of gear train.

Describe concrete structure of the present utility model in detail according to Fig. 1-3.This device comprises parts such as cylindrical shell 7, protecgulum 10, bonnet 3, going barrel 5, gear train 6, permanent magnet TRT, lamp socket 8, bulb 9, lampshade 11.Screw bulb 9 on its middle cylinder body 7 front end lamp sockets 8, optically focused lampshade 11 is fixing by transparent gland and protecgulum 10.For improving its junction surface waterproof ability, can between lampshade 11 front ends and transparent gland, seal washer be set.The permanent magnet TRT is made of stator coil 14, rotor permanent magnet 13, the rotating shaft 15 etc. that has an end tooth wheel 19.Wherein coil 14 outputs and lamp socket 8 both positive and negative polarities connect, and permanent magnet 13 is packed in the rotating shaft 15, the end tooth wheel 19 and the gear train 6 final stage gears engaged of rotating shaft 15 1 ends.Gear train 6 adopts the mechanical transmission structure form of clock, and present embodiment adopts six grades of transmissions.Its final stage gear is meshed with the end tooth wheel 19 of rotating shaft 15, and its chopped-off head gear is meshed with going barrel 5 end driving gears 17.For controlling each gear rotational speed, escapement (its structure is identical with the clock drive mechanism with installation form) 18 is set betwixt, make gear train 6 rotary speeies stable.In cylindrical shell 7 rear ends going barrel 5 is set, the clockwork spring in the going barrel 5 is rolled up 4 one ends and is fixed on the going barrel 5, and the other end is fixed on the driving shaft 1.Driving shaft 1 utilizes one-way wheel 16 and connector 2 to be assembled on the movable gland 3.Connector 2 is packed on the movable bonnet 3.When rotation bonnet 3, one-way wheel 16 drives driving shaft 1 and rotates thereupon, and clockwork spring volume 4 tightly wraps on driving shaft 1.Revolve completely, under driving shaft 1 self elastic force effect of clockwork spring volume 4 thereon, driving shaft 1 screws the backward rotation of direction along bonnet 3, and one-way wheel 16 idle running are inoperative.The driving gear 17 that drive shaft rotating 1 drives going barrel 4 ends rotates.6 work of driving gear 17 drive gear set drive the rotating shaft 15 that is meshed with its final stage gear and rotate, and make permanent magnet 13 quick rotation, cutting magnetic line, and coil 14 output output currents ignite bulb 9.For making cylindrical shell 7 rear ends improve waterproof ability, can between driving shaft 1 periphery and cylindrical shell 7 hole walls, seal washer be set.

During use, turn activity bonnet 3 drives driving shaft 1 rotation and makes clockwork spring volume 4 energetically.Man Jinghou, clockwork spring volume 4 utilizes the elastic force of self to make driving shaft 1 backward rotation, the driving gear 17 that drives going barrel 5 ends rotates, start working with its meshed gears group 6, driving rotating shaft 15 rotates, thereby the permanent magnet 13 of rotation is rotated in stator coil 14, and coil 14 produces electric current makes bulb 8 shinny.
