Abstract
The utility model discloses a handheld rechargeable flashlight, which comprises a shell, a lighting source, a battery and a manual power generation mechanism; wherein the manual power generation mechanism consists of a generator and a driving mechanism; the driving mechanism drives the generator to rotatingly generate power so as to provide electrical power for the lighting source for lighting and/or charge the battery. In the utility model, the manual power generation mechanism is arranged in the inner part of the flashlight, so that the dry battery is not needed; when in use, the power is generated only by rotating the rocker arm handwheel, and the flashlight has simple structure and convenient use, and is particularly applicable to mountainous areas and field operations.
Description
Technical field
The utility model relates to charging and field of illuminating device, refers to a kind of flashlight that has electricity generated manually mechanism especially.
Background technology
Existing flashlight generally adopts dry cell as power supply, has so both wasted battery, increases the trouble that more renews battery again.
The utility model content
At the problem that prior art exists, the purpose of this utility model be to provide a kind of need not dry cell, by the flashlight of the miniature power generating device self power generation that carries.
For achieving the above object, the utility model is held chargeable electric torch, comprise shell, light emitting source, battery and electricity generated manually mechanism, described electricity generated manually mechanism is made up of generator, driving mechanism, the described generator rotary electrification of described drive mechanism provides electric power luminous and/or to described charge in batteries for described light emitting source.
Further, described driving mechanism comprises rocking arm handwheel and change-speed gearing, described rocking arm handwheel and the engagement of described change-speed gearing, and change-speed gearing and described generator shaft are rotationally connected.
Further, be serially connected with diode in the described battery charging circuit.
Further, also be provided with the charging jack on the described shell, described charging jack is used for to the external connected electronic equipment charge.
Further, described generator provides electric power to be controlled by first switch to described charge in batteries or to described light emitting source.
Further, described first switch is the two switches of putting of hilted broadsword.
Further, whether described battery is controlled by second switch described light emitting source power supply.
Further, described battery is the 3.7V chargeable lithium cell.
Further, described light emitting source is the LED lamp.
The utility model is held chargeable electric torch and is provided with electricity generated manually mechanism in flashlight inside, need not use dry cell, need only stir the generating of rocking arm handwheel during use and get final product, and this flashlight structure is simple, and is easy to use, is particularly suitable for mountain area and field work and uses.
Description of drawings
Fig. 1 is the circuit diagram of the utility model flashlight;
Fig. 2 is the fundamental diagram of the utility model flashlight.
The specific embodiment
As illustrated in fig. 1 and 2, the utility model is held chargeable electric torch, comprise the LED lamp, shell, 3.7V lithium battery 1 and electricity generated manually mechanism, electricity generated manually mechanism is by generator, change-speed gearing and rocking arm handwheel formation; rocking arm handwheel and change-speed gearing connecting portion have tooth; change-speed gearing and generator shaft are rotatably connected; the rocking arm handwheel is provided with return spring; stir the rocking arm handwheel and drive the change-speed gearing rotation; thus drive generator for electricity generation; and the two switches of putting of hilted broadsword are controlled generators to 1 charging of 3.7V lithium battery or directly to the power supply of LED lamp; generator is serially connected with diode in 3.7V lithium battery 1 charging circuit; 3.7V lithium battery 1 is controlled by another switch 3 to the power supply of LED lamp; generator can gauge tap 3 closures be powered to the LED lamp by 3.7V lithium battery 1 to the 1 charging while of 3.7V lithium battery; 3.7V lithium battery 1 two ends also are connected with jack 2 in addition, can be mobile phone or the charging of other electronic product.
In order to guarantee to produce enough electric energy, the coil turn of generator can be made corresponding adjustment as required.
The utility model Handheld rechargeable flashlight is provided with manual generator in flashlight inside Structure need not use dry cell, need only stir the generating of rocking arm handwheel during use and get final product this flashlight Simple in structure, easy to use, be particularly suitable for mountain area and field work and use, and light emitting source is adopted With the LED light fixture advantages such as energy-conservation, good illumination effect are arranged.
