Description
Technical field
The utility model provides a kind of flashlight with electric generation by itself, especially a kind of flashlight that can utilize the realization of the swing naturally self-generating illumination reel of arm.
Background technology
Flashlight is the widely used daily necessitiess of people, generally provide electric energy with dry cell, not only need consume in battery, the disposal behind the used for dry cell also is an environmental problem, need not use dry cell as flashlight energy self power generation, its economic benefit and environmental benefit are self-evident.Present realization flashlight with electric generation by itself comparatively mature technique scheme is by the outer pressure handle of flashlight, instruments such as crank do work to flashlight, acting promotes rotating speed rear drive generator for electricity generation through the rotating speed lifting device, or be stored in the scroll spring, promote rotating speed rear drive generator for electricity generation by its slow release and by the rotating speed lifting device, the patent No. is 02220353.2,8209097.8 and 99223619.3 publication all belongs to this type of scheme, this type of scheme product needed user does not move to the lasting acting of flashlight naturally with pushing pressure handle or rotation crank etc., user's fatiguability particularly uses particularly inconvenience when walking.Need should be mentioned that especially and mention the escapement element in 99223619.3 schemes and pendulum element title of the present utility model is closely similar, but the effect of its escapement is control rotating shaft uniform rotation that the utility model then is to utilize pendulum to realize power conversion, effect is different.
Summary of the invention
The purpose of this utility model provides a kind of flashlight with electric generation by itself of more convenient practicality, solves the technical problem that natural swinging arm institute work is changed into electric energy realization self-generating illumination reel.
For realizing the purpose of this utility model, the utility model partly is made up of light-emitting component, microgenerator, rotating speed lifting device, housing etc., the utility model design has pendulum, pendulum is connected with the swing fulcrum shaft of fixed-site in housing, and pendulum can be around swing fulcrum shaft positive and negative two to swing; The power transferring structure that has the wheel for inputting that makes the rotating speed lifting device or power shaft to rotate between pendulum and the rotating speed lifting device with the swing of pendulum; The output wheel of rotating speed lifting device or output shaft are connected with the micro generation machine rotor; Described rotating speed lifting device is can be with the positive and negative two rotating speed speed change gears to rotation lifting rotating speed of wheel for inputting or power shaft.The utility model operation principle is as follows: when arm is swung naturally, its palm portion is seesawing of approximate circle arcuation, when swinging plane of holding the utility model with palm and making pendulum and the palm portion plane that seesaws substantially parallel, the swing fulcrum shaft is followed the palm motion, and drive and to be attached thereto the pendulum motion that connects and to make pendulum have kinetic energy, while is connected with the swing fulcrum shaft owing to pendulum and swings the fulcrum shaft fixed-site, make pendulum can only do around the swing fulcrum shaft positive and negative two to oscillating motion, so, pendulum has been accepted the palm portion institute's work that seesaws by the swing fulcrum shaft; Pendulum positive and negative two passes to the rotating speed lifting device to oscillating motion by the power transferring structure with it, and wheel for inputting or power shaft are rotated forward or backwards, and both pendulum utilized force transfer mechanism further the merit of accepting to be changed into the input of rotating speed lifting device; Since the rotating speed lifting device can with wheel for inputting or power shaft positive and negative two to rotate promoting rotating speed, make positive and negative two after the rotation input all can promote rotating speed, to export by output wheel or output shaft, drive is attached thereto the microgenerator rotor rotation that connects, and makes the microgenerator generating; Generate electricity and can supply with the light-emitting component luminous lighting.Thus, power transferring structure and microgenerator and light-emitting component between swing fulcrum shaft, pendulum, rotating speed lifting device, pendulum and the rotating speed lifting device, constituted jointly palm portion arm can be swung naturally the time seesaw do work, change into the energy conversion system of electric energy and luminous energy, realized the purpose of self-generating illumination reel.
For the utility model institute luminance is not rocked with the arm reciprocally swinging, the lamp holder that the utility model is installed light-emitting component separates with the flashlight body that power supply is provided, and connects by lead between the two.
Be fixed with two spring leafs on the housing of the present utility model, an end of spring leaf is fixed on the housing, and the other end is pressed rightabout respectively and pointed to pendulum along the pendulum arc of movement.The effect of two spring leafs be shorten in the pendulum reciprocally swinging process two conversion direction of motion points and near the period duration, when pendulum during near conversion direction of motion point, kinetic energy is exhausted gradually, the movement velocity of pendulum slows down, microgenerator output voltage and power are descended rapidly, influence light-emitting component work, by two spring leafs are set, and the on-fixed end of spring leaf can be contacted before conversion direction of motion point with pendulum, behind the pendulum swing contact spring leaf, the resistance of spring leaf slows down pendulum rapidly to stop, and the rebound effect of spring leaf has been accelerated the commutating speed of pendulum simultaneously, and give the reverse initial velocity of pendulum, shortened pendulum commutating period.The on-fixed end in contact face of pendulum and spring leaf is advisable in the center position of pendulum side.
The beneficial effects of the utility model are to change into electric energy and luminous energy realization self-generating illumination reel to swing arm institute work, because swinging arm is people's action naturally, therefore the action naturally when particularly walking has improved the convenience and the practicality of use.
