Abstract
A flashlight capable of realizing continuous charging through hand pressing. The device is mainly composed of a crank rocker mechanism, a gear set, a generator, a battery pack and an LED bulb. The crank rocker mechanism is a power generation mechanism, the grab handle is a rocker part of the crank rocker mechanism and can swing in a reciprocating mode, the crank and the large gear are integrated, and the grab handle drives the large gear to rotate continuously through the connecting rod. The big gear is meshed with the small gear, the small gear is connected with the generator, and the gear set has an accelerating effect and finally drives the generator to run rapidly and continuously. The grab handle is continuously held and pressed by hands, so that continuous charging is realized.
Description
Technical field
The utility model relates to a kind of self-charging flashlight, is specifically related to a kind of flashlight that can realize trickle charge by hand.
Background technology
Most of in the market chargeable flashlight depends on electric power, the indoor power supply that utilizes that has charges, the common disposable dry cell power supply of the employing that has, in case the greatest weakness of these products be to run into have a power failure or go out, battery electric quantity uses up and will cause lighting apparatus to work.Another kind of new product on the market is built-in electricity generated manually mechanism, promptly do work by human body, kinetic energy is converted to electric energy, the hand generating of hand-rail type generating and ratchet structure is arranged usually, the former can trickle charge, and complicated operation is though the latter is simple to operate, but can not trickle charge, generating efficiency is not high.
Summary of the invention
In order to overcome the deficiency of the not high and complicated operation of existing self-charging flashlight generating efficiency, the purpose of this utility model provides a kind of hand self-charging flashlight that has crank and rocker mechanism, in this flashlight power facility is arranged, specifically provide continuous mechanical energy by crank and rocker mechanism, and then be converted into electric energy, realize operation by the hand lever, simply comfortable.
The technical scheme that its technical problem that solves the utility model adopts is: device inside mainly is made up of crank and rocker mechanism, gear train, generator, battery pack and several parts of LED bulb.The power conversion that crank and rocker mechanism is used for human body acting is a mechanical energy, and lever is the rocking bar part of crank and rocker mechanism, can reciprocally swinging, and crank and gear wheel are one, lever drives gear wheel by connecting rod and continues rotation.Gear wheel is meshed with pinion, and pinion is connected with generator, and gear train has acceleration, finally drives generator running continuously fast.When the hand lever, connecting rod drives gear wheel and rotates, and the large gear turn the small gear rotates, and drives generator after pinion quickens and runs up, and produces electric energy.When openhanded when opening lever, under the effect of spring, the lever resilience, connecting rod continues the driven gear group and generator rotates, thereby realizes uninterruptable power generation.Stir a dead-centre position that can overcome crank and rocker mechanism.Stir head and be fixedly connected on the shell, can rotate along its fixed axis.The battery pack store electrical energy.The LED bulb discharges the form of electric energy with luminous energy, realizes illumination.
The beneficial effects of the utility model are, crank and rocker mechanism can provide continuous mechanical energy in power generation process, improved generating efficiency, user's simple and comfortable operation, situation such as be suitable for having a power failure, go out, and the dependence for disposable battery has been avoided in the design of can generating electricity, and has reduced the pollution to environment.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a structure chart of the present utility model.
1. levers among the figure, 2. spring, the 3.LED lamp holder, 4. generator, 5. pinion, 6. gear wheel is 7. stirred head, 8. connecting rod, 9. battery, 10. shell.
The specific embodiment
In the drawings, connecting rod (8) and lever (1) and gear wheel (6) the composition crank and rocker mechanism that links together, hand lever (1) drives gear wheel (6) by connecting rod (8) and rotates, gear wheel (6) is meshed with pinion (5) and realizes quickening, pinion (5) is connected with generator (4), drives generator (4) and runs up.Spring (2) guarantees that lever (1) resets, and stirs head (7) and can overcome the dead-centre position, makes gear wheel (6) continue rotation.Battery (9) stores the electric energy that produces, and LED lamp holder (3) is realized illumination, and shell (10) plays attractive in appearance and protective effect.
Claims (3)
