Abstract

The utility model relates to a labor saving self-generating electric torch, comprising a shell, a buld, a set of microgenerator assembly, and a driving device of the microgenerator assembly, and is composed of a grab handle rack bar, a bidirectional ratchet wheel and ratchet pawl teeth combination assembly, positive direction ratchet teeth, reverse direction ratchet teeth, a reversing transition wheel group, two sets of driving gear groups and a reset torsion spring. The utility model can be used as a good body-building device with the advantages of high energy conversion efficiency and labor saving.

Description

Power-saving self-generating electric torch

It is a kind of without battery that the utility model belongs to, and mechanical energy is converted to the portable lighting tool of electric energy, also can use as fitness tool simultaneously.

Existing flashlight generally provides electric energy by battery, and is simple in structure, easy to use, but if no words of long period, then battery power meeting in the torch " run away ", and its electrolyte also very easily flows out and corrodes torch shell and other object.Therefore, have the people once to invent a kind of flashlight with electric generation by itself, it is driven by lever, drives a microgenerator generating by a cover transmission device.Though this flashlight can play the self power generation effect, because it has only utilized the power of hand lever, and the reseting procedure of lever fails to utilize, thus mechanical energy to convert the efficient of electric energy to lower, physical demands is bigger.

The purpose of this utility model is to overcome the defective of above-mentioned flashlight with electric generation by itself, provides a kind of energy conversion efficiency higher effort-saving flashlight with electric generation by itself.

Major technique measure of the present utility model is as follows:

A kind of laborsaving flashlight with electric generation by itself, have housing, small electric bulb and a cover micro generation thermomechanical components, it also has the drive unit of a cover micro generation thermomechanical components, this drive unit is by the lever tooth bar, two-way click tooth combine component, forward hook tooth, reverse hook tooth, commutation transition gear group, two cover driving gear set and the torque spring that resets are formed.

Energy when the utility model both can be with hand lever tooth bar converts the electric energy that generator sends to by transmission mechanism, the potential energy that thereby the compression torque spring is accumulated in the torque spring in the time of again can be with hand also converts the electric energy that generator sends to by transmission mechanism, thereby conversion efficiency height, laborsaving, also can use simultaneously as a kind of good health and fitness facilities.

Description of drawings:

Fig. 1 is laborsaving flashlight with electric generation by itself structural representation

Fig. 2 is the transmission mechanism schematic diagram

Among the figure: the 1st, the lever tooth bar, the 2nd, two-way click tooth combine component, the 3rd, the forward hook tooth, the 4th, reverse hook tooth, the 5th, commutation transition gear group, 6,7 is gear train, the 8th, the micro generation thermomechanical components, the 9th, torque spring resets.

Its operation principle is as follows:

When holding moving lever tooth bar 1, promptly drive two-way click tooth combine component 2 and rotate, drive forward hook tooth 3 by its forward ratchet and rotate, and then reach gear train 6,7, drive 8 generatings of micro generation thermomechanical components; After hand is decontroled, torque spring 9 resets lever tooth bar 1, drive click tooth combine component 2 backward rotation, driving reverse hook tooth 4 by its reverse ratchet rotates, after by commutation transition gear group 5 backward rotation being become forward rotation, reach gear train 6,7, thereby drive 8 generatings of micro generation thermomechanical components.So go round and begin again, just can export electric energy continuously, it is luminous to light small electric bulb.

Claims (1)

1, a kind of laborsaving flashlight with electric generation by itself, have housing, small electric bulb and a cover micro generation thermomechanical components, it is characterized in that: it also has the drive unit of a cover micro generation thermomechanical components (8), and this drive unit is made up of lever tooth bar (1), two-way click tooth combine component (2), forward hook tooth (3), reverse hook tooth (4), commutation transition gear group (5), gear train (6,7) and the torque spring that resets (9).
