Abstract
The utility model relates to an electric torch with a generator driven by hand grasping, comprising a barrel body, a buld, a handle, the generator, and a speed changing gear, and is characterized in that the handle is a double rack bars and is arranged symmetrically on the center wheel of a big gear (4). Left and right three-tooth overspeed clutch wheels (14) (15) and a left three-tooth overspeed clutch wheel (14) are connected with a left small gear 5. A right three-tooth overspeed clutch wheel (15) is connected with a right small gear (6). A left rack bar (2) is engaged with the left small gear 5. A right rack bar (3) is engaged with the right small gear (6). The utility model has the advantages of small starting torque, labor saving, continuous generating electricity, small size, and portability.
Description
The utility model relates to a kind of flashlight without battery, be household person carry the generating illuminations be electrical technology field.
When monodentate bar handle " held torch " and be toward downforce in " hold send out a flashlight " abbreviations of the domestic and international production that the utility model is the most close, tooth bar interlock gear wheel again the rotation of gear wheel interlock generator gear and generate electricity, handle is the flickering brightness instability of small electric bulb that dallies during toward resilience by spring force.Former use ferrite is done magnetic pole, and the big generated energy power of magnetic force small size is little.Can only use 0.2 watt of the special low-power bulb of producer (small electric bulb).
The purpose of this utility model provides a kind of solution and overcomes the above shortcoming that go up to exist former " holding torch " and finish problem, increases by a tooth bar on handle, becomes double rack, has solved the brightness shakiness thereby move back and forth.
The technical characterictic that the utility model is complete is to hold power generation flashlight, comprise stack shell, small electric bulb, handle, generator, change-speed gearing, it is characterized in that: handle is that double rack is symmetrical set on gear wheel (4) centre wheel, about three teeth hypervelocities castle wheel (14) (15), left three teeth hypervelocity castle wheels (14) link to each other with left pinion 5.Right three teeth hypervelocity castle wheels (15) link to each other with right pinion (6), left tooth bar (2) and left pinion (5) interlock.Right tooth bar (3) and pinion (6) interlock.Be on former handle, to increase a tooth bar, when handle when the downforce, being embedded in gear wheel right side pinion by the right side tooth bar interlock that links to each other with handle, is that a whole drive gear wheel interlock generator gear rotation is generated electricity by hypervelocity castle wheel and pinion, and at this moment another tooth bar is idle running.When handle by spring pressure when the resilience, tooth bar interlock left side, left side pinion drives gear wheel and rotates, no matter press down or be subjected to equidirectional pressure all the time during resilience at handle, the rotation that gear wheel is not stopped, fluctuating acceleration is rotated generator at a high speed and is reached stable electric generation.Microgenerator with neodymium iron boron as excitation be disc type ends of the earth structure as rotor, generator coil is that no iron core formula, starting torque are little, is stator.It is invariable that per minute is held 20 bright changes; Behind rotor starting, utilize the inertia of lining wheel at rotor cylindrical direct casting one lining wheel.Rotation remains a constant speed when the gap that handle is back and forth transferred.
Outward appearance is the square lamp holder of prolate, with a kind of size of stack shell, and lamp holder inclination 40 degree angles.
The utility model further specifies in conjunction with the accompanying drawings.
Fig. 1 is that the utility model is held the power generation flashlight structural representation.
Fig. 2 is the A-A profile of Fig. 1.
Fig. 3 is the utility model circuit diagram.
Fig. 4, Fig. 5 are three tooth parabola castle wheel schematic diagrames.
The right three teeth hypervelocity of the left three teeth hypervelocity castle wheels of the right pinion of the left pinion of the right tooth bar of the left tooth bar of (1) handle (2) (3) (4) gear wheel (5) (6) (7) generator gear (8) generator amature (9) axle (10) electricity generator stator coil (11) spring (12) bulb (13) needle roller (14) (15) castle wheel (16) Large Gear Shaft During (17) generator shaft among Fig. 1,2,3.
From Fig. 1,2,, when giving handle (1) plus-pressure (down by), press right tooth bar (3) and right pinion (6) interlock, three gear centrifugal wheels (15) and gear wheel (4) interlock.Pinion other end, the left and right sides is that three tooth parabolas hypervelocity castle wheel is an integral body, be embedded in center, gear wheel both sides recess respectively, all on same axle, (4) with generator gear (7) interlock, drive generator amature (8) fast rotational, left side tooth bar (2) and left pinion (5) interlock, but at this moment three tooth centrifugal wheels (14) dally, and do not get in touch with gear wheel (4).Have only after handle loosens, under spring reaction power, during toward resilience, left side tooth bar (2) also up drives pinion (5) thereupon, (14) interlock, (4) interlock again, (7) make generator continue to rotate always, finish a process as hereinbefore, moving in circles like this reaches the purpose of uninterruptable power generation.At this moment right tooth bar (3) dallies with pinion (6).
The alternating action of right tooth bar (3) and pinion (6) and left tooth bar (2) and pinion (5), (14), (15) two-wheeled are installed in the other direction.(4) finish by three tooth parabolas hypervelocity castle wheel with (14) and (4) and the clutch of (15).
Fig. 4, three teeth shown in Figure 5 hypervelocity castle wheel are that prior art is not described further at this.
