The specific embodiment

Below in conjunction with accompanying drawing, a specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subject to the restriction of the specific embodiment.It will be appreciated that, mentioned in following embodiment of the present invention " on ", D score, " left side ", " right side ", " front " and " reverse side " all take the direction shown in each figure as benchmark, these words that are used for limiting direction are only used to be convenient to explanation, do not represent the restriction to the concrete technical scheme of the present invention.

(in figure, arrow represents direction of rotation) as depicted in figs. 1 and 2, gravity lighting lamp of the present invention carries microgenerator, utilize desk lamp body assembly along column tooth bar, to fall to drive microgenerator generating under the effect of gravity, and then be the power supply of desk lamp illuminating lamp, concrete structure comprises: base 1, column tooth bar 2 and desk lamp body assembly.

Column tooth bar 2 is vertically fixed on base 1 by lower end, and column tooth bar 2 one side are as the pillar of desk lamp body assembly, the rack-track that falls to generating electricity under the effect of gravity as desk lamp body assembly on the other hand.

Desk lamp body assembly comprises: desk lamp body 31, and be arranged on driven wheel 32, driven pulley 33, transition gear 34, output ratchet 35, output gear 36, ratchet 37, microgenerator 38 and the illuminating lamp 39 in this desk lamp body 31.Wherein, driven wheel 32 is arranged on the left side of desk lamp body 31 by rotating shaft, and forms rack-and-pinion transmission by left side and 2 engagements of column tooth bar, when desk lamp body assembly is fallen under the effect of gravity, driven wheel 32 turns clockwise, as the driving force of microgenerator 38 generatings.

Driven pulley 33 is coaxial size two gear arrangements, and pinion is meshed with driven wheel 32, and gear wheel is meshed with the transition gear wheel of transition gear 34.The rotating shaft of driven pulley 33 is arranged on desk lamp body 31, this rotating shaft installing hole is the long arc-shaped holes concentric with driven wheel 32, can tape spool circumference micro-swinging when driven pulley 33 is rotated under the drive of driven wheel 32, wherein cut off the engagement with transition gear 34 during counter-clockwise swing, while swinging clockwise, connect the engagement with transition gear 34, be desk lamp body assembly when moving on column tooth bar 2, driven wheel 32 is rotated counterclockwise, driven pulley 33 counter-clockwise swing that turns clockwise, cut off the engagement with transition gear 34, like this, not to transition gear 34 transmission driving forces, on facilitating, move simultaneously, and desk lamp body assembly is when fall along column tooth bar 2, driven wheel 32 turns clockwise, and driven pulley 33 is rotated counterclockwise clockwise swing, connects the engagement with transition gear 34, to transition gear 34 transmission driving forces, drives microgenerator 38 generatings.

Transition gear 34 is also coaxial transition gear wheel 341 and the assembly of main ratchet 342, and wherein, transition gear wheel 341 is meshed with the gear wheel of driven pulley 33, and by main ratchet 342 driver output ratchet 35 rotations.

As shown in Figure 3, output ratchet 35 is secondary ratchet 351, side circumference gear 352 and outer gear wheel 353 assemblys, wherein, secondary ratchet 351 and side circumference gear 352 coexistence inner sides (left side), and the output secondary ratchet 351 of ratchet 35 and the interior ratchet-pair that meshes into of the main ratchet 342 of transition gear 34, and when transition gear 34 clockwise rotates, main ratchet can drive secondary ratchet to rotate, transition gear 34 rotates counterclockwise and can not drive secondary ratchet to rotate, main ratchet slides in secondary ratchet, by transition gear 34, transmitted the power coming and pass to output ratchet 35 through this ratchet-pair, the side circumference gear of output ratchet 35 is connected output with output gear 36 by 90 °, output gear 36 drives the power shaft of microgenerator 38 to rotate generating.

Ratchet 37 comprises: by ratchet rotating shaft, being fixed on the swing seat on desk lamp body 31 and being fixed on these two ends, swing seat left and right has control lever, two ends control lever can be with swing seat around ratchet shaft swing, two control levers are meshed with the outer gear wheel 353 of output ratchet 35, for controlling rotating speed and the rotation direction (output ratchet 35 can only rotate to a direction) of output ratchet 35, the rotating speed of output ratchet 35 is controlled, desk lamp body assembly is slowly fallen along column tooth bar 2 under the effect of gravity, rhythmical potential energy is converted into electric energy, increase the generating dutation once falling, prevent that desk lamp body assembly from falling fast, cause voltage instability, waste of energy, and the troublesome operation and the component wear that repeatedly, move desk lamp body assembly.

During application, desk lamp body assembly moves on to column tooth bar 2 tops on the whole, column tooth bar 2 drives driven wheel 32 to rotate counterclockwise, and drive can circumference micro-swinging driven pulley 33 also inverse clock swing, cut off the engagement with transition gear 34, thereby cut off the output of power, microgenerator 38 does not have electric energy output.Otherwise, when lifting desk lamp body assembly is decontroled in tooth bar 1 top, desk lamp body 31 is owing to slowly being moved down by the impact of gravity, drive driven wheel 32 to clockwise rotate, and oppress and can swing by circumference micro-swinging driven pulley 33 clockwises, the engagement of connection and transition gear 34, has driven 35 rotations of output ratchet, thereby the dynamic microgenerator 38 that outputs to desk lamp, so just there is electric energy output to drive illuminating lamp 39 luminous.

This gravity lighting lamp is simple and reasonable, can utilize desk lamp body assembly along column tooth bar, to fall to drive microgenerator self power generation under the effect of gravity, as lighting lamp power, avoided the dependence of existing lighting lamp to civil power or battery, expanded the scope of application; Meanwhile, utilize microgenerator self power generation energy-conserving and environment-protective, and improved service time.

Disclosed is above only several specific embodiment of the present invention, and still, the present invention is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
