Abstract

The utility model relates to a hand-operated portable electricity generated lamp, which is used as an illuminating tool at night. Slow clamping or rotating of fingers are used as dynamic force to drive a microgenerator to generate electricity through a buffer and a speed change mechanism to lighten a small bulb to emit light. So the purpose of illumination can be achieved. The utility model dose not use a battery with the advantages of low manufacture cost and economy.

Description

Hand-operated portable electricity generated lamp

The utility model relates to a kind of domestic lighting utensil.

Usually the flashlight that uses as illumination, generally be with dry cell or battery as power supply, light bulb and make it luminous, reach illumination purposes.This mode has some such problems, makes the flashlight of power supply with dry cell, needs often to change dry cell, and so promptly trouble is also uneconomical, if for a long time need not, dry cell also is easy to rot in flashlight, damages flashlight.Make the flashlight of power supply with battery, also need frequent charging, if charging operations is improper, such as " owing to fill ", " overcharging " or " forgetting to fill ", all can shorten the service life of battery to a great extent, and, the price of battery is also more expensive, once damage, generally the battery that can not more renew makes itself and torch take to fall together.

The purpose of this utility model provides a kind of flashlight without battery.It only with moving its handle of the upper and lower slowly pincers of the finger of a hand, just can make bulb luminous effectively, reaches illumination purposes.

The purpose of this utility model is achieved in that meshing by a right angle tooth bar and right angle gear, the upper and lower motion of handle is changed into the one-directional rotation of right angle gear, this rotates volute spring of drive and makes its rolling-in, save part energy, the dispensing end of volute spring drives another gear and constantly rotates continuously, and this rotates by a speed change link and drives a microgenerator rotation, makes its generating, generate electricity and can light bulb, make it continuously luminous.In order can not burn bulb, be provided with a voltage clamp circuit at the output of microgenerator, so that output voltage can not surpass the highest limit value because of rotating speed is too fast.

Because the utility model has used microgenerator, so can be without battery.Become rotation so that the upper and lower pincers of finger are moving, it is convenient and laborsaving especially to make it operation.Its volute spring not only plays the effect of temporary transient accumulation of energy, and the more important thing is the mechanical damping effect of having played, because its existence, microgenerator is turned round continuously, rather than intermittent running, thereby can make bulb normally luminous, change-speed gearing can make rotating speed reach as the setting of a speed change link or near the rated speed of microgenerator.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the front view according to the hand generating lantern that the utility model proposes.

Fig. 2 is the left view of front view.

Fig. 3 is the A-A cutaway view of left view.

Fig. 4 is voltage clamp circuit figure.

Describe details and working condition in detail below in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4 according to the concrete mechanism that the utility model proposes.

Consult Fig. 1, this mechanism comprises a upper and lower movable handle of energy (1); One is fixed together with handle (1), and can serve as the right angle tooth bar (3) that a low-angle swings with axle (2); Under the effect of making leaf spring (4), make right angle tooth bar (3) and right angle gear (5) together meshing; Ending anti-valve (6) can only rotate by folk prescription right angle gear to the inverse time; With the coaxial file spring board that is fixed together of right angle gear (5) (7).Consult Fig. 1 and Fig. 3, locate to be provided with a fixedly pin (10) of volute spring (9) inner termination near axle (8) at file spring board (7); The external end head of volute spring (9) is fixed on the outer peripheral pin of gear (11) (20); Gear (11) is meshing with gear (12), and gear (12) is coaxial fixing with gear (13).Consult Fig. 2, gear (13) is meshing with gear (14), and gear (14) is fixed together with the rotating shaft (16) of microgenerator (15).Consult Fig. 2 and Fig. 4, the outlet terminal of microgenerator (17) is in parallel with the terminals (18) and the voltage clamp circuit of bulb.Voltage clamp circuit is made up of a voltage-stabiliser tube W and a current-limiting resistance R; when the output voltage of microgenerator surpasses limit value; electric current is missed by voltage-stabiliser tube and current-limiting resistance; to ensure that output voltage is fixed under the rated voltage of bulb by pincers, play the unlikely effect of being burnt of protection bulb.

Consult Fig. 1,2, when people's finger upwards clamps fixed handle (1), right angle tooth bar (3) moves upward with handle (1), while compression handles inner spring (19), right angle tooth bar (3) is meshing with right angle gear (5) under the pressure of making leaf spring (4), and it is rotated counterclockwise, because the right angle gear profile of tooth is ended anti-valve (6) and can not be stopped rotating counterclockwise of right angle gear.File spring board (7) is coaxial and rotate counterclockwise with angular speed with right angle gear (5).Consult Fig. 3, be arranged on file spring board (7) and go up the pin of locating near axle (8) (10) and make volute spring (9) rolling-in and force in and be fixed on the outer peripheral pin of gear (11) (20), thus driven gear (11) rotation.Consult Fig. 2, gear (11) drives change-speed gearing (12) rotation, because gear (12) is coaxial fixing with gear (13), so gear (13) drives gear (14) rotation on microgenerator (15) axle, it is luminous to make the microgenerator generating light bulb.When finger release handle (1), compressed handle inner spring (19) resets, and moves downward thereby drive right angle tooth bar (3), because profile of tooth, ends anti-valve (6) and makes right angle gear (5) can not reverse (promptly can not clockwise rotate).So, can not rotate right angle gear at this moment, right angle tooth bar (3) can only overcome the pressure of making leaf spring (4) and throw off with right angle gear (5) and move downward when moving downward.

Lead agency motion and part accumulation of energy when this process makes it handle and moves upward, and release handle is walked sky when promptly handle moves downward, reset for move upward next time.

This mechanism also can not be provided with handle (1) and right angle tooth bar (3), but directly rotate right angle gear (5) with hand, or right angle gear (5) extended makes a swing handle, with the rotation of hand as the powered rotation swing handle, though this side's one mode is simply also in full force and effect.

This mechanism also can directly drive the microgenerator generating only by the speed change link, is about to change-speed gearing (12) extension and makes swing handle, rotate with hand, though generate electricity can be discontinuous for microgenerator like this, bulb will be intermittently luminous, use also in full force and effect as illumination.

The microgenerator that this mechanism adopted (15) replaces with dc motor, uses as dc generator, though simple economy is also in full force and effect.
