The specific embodiment

Followingly describe technical characterictic of the present utility model and beneficial effect in detail according to preferred embodiment of the present utility model and conjunction with figs..

Fig. 1 and Fig. 2 are the annexation schematic diagrames of overall appearance and the transmission mechanism part of the utility model one embodiment.When human body is stepped on pedal 5 motions, the hand swing arm that push-and-pull simultaneously links to each other with support bar 4 with upper arm participates in driving driving wheel 1 and rotates, driving wheel 1 drives driven pulley 7 by driving-belt 8 and rotates, thereby make generator 2 generatings, the electrical power storage that produces is in battery, and 3 have comprised battery, control circuit and output interface among the figure.

In the present embodiment, drive can be a belt pulley, also can be sprocket wheel.

In the present embodiment, the radius of driving wheel is 20 centimetres, and the radius of driven pulley is 2 centimetres, and the radius ratio of driving wheel and driven pulley is 10: 1, just R: r=10: 1, and this is that the rotating ratio between driving wheel and the driven pulley is 1: 10.

When the rotating speed of driving wheel, when just person taking exercise's motion rotating speed reached per minute 40 to 80 circles (40-80rpm), generator reached rated speed 240-400rpm.At this moment, effective driving force that human body acts on the pedal reaches about 30 kilograms, and generator reaches about 250 watts of rated power.

Can see from top parameter, with effective driving force of 30 kilograms, the physiology of exercise characteristics when meeting most of people fully and on elliptical machine, take exercise by the rotary speed movement about per minute 40 circle.In fact, for elliptical machine, as long as the user stands on the machine, chimb over the water, the generator of leaning to one side then just begins to have generated electricity.This makes children and the elderly also can use the utility model like a cork equally.

In the above-described embodiments, have an end to be connected with spring 6 between pedal 5 and the support bar 4, the sole position that can adapt to human body diverse location when motion like this is the variation and the corresponding angle of inclination of point firmly, to reach good ergonomics comfort level.

Fig. 4 is the embodiment that another kind has adopted crank and guide rail structure.In the 200610078954.X patent document, mentioned the elliptical machine that adopts crank and guide rail structure.Present embodiment has also been used for reference similar structure at motion parts.An end of crank 14 and driving wheel articulate among the figure, and the other end is a roller 13, and roller 13 rolls on guide rail 11, and an end of support bar 4 and crank 14 articulate.When human body drove the support bar motion, an end of crank 14 drove driving wheel 1 and rotates, and the other end is rolling on guide rail 11 by roller 13.

In the present embodiment, have an end to be connected with spring 6 equally between pedal 5 and the support bar 4, the sole position that can adapt to human body diverse location when motion like this is the variation and the corresponding angle of inclination of point firmly, to reach good ergonomics comfort level.

What need at last to remark additionally is, adopt belt pulley or sprocket wheel to come the two-stage drive mechanism that the primary structure of transmission can expand to equally increases a breast wheel between driving wheel that reaches described in the utility model and the driven pulley: driving wheel drives breast wheel and rotates, and breast wheel drive driven pulley rotates.The mechanical mechanism mentality of designing of body-building elliptical machine has been enriched in the existence of breast wheel, also can be used for adjusting the rotating ratio relation of driving wheel and driven pulley simultaneously.

That Fig. 5 shows is exactly a kind of two-stage drive mechanism embodiment that has increased breast wheel.Between driving wheel 1 and driven pulley 7, there is a breast wheel 9, connects by driving-belt 81 between driving wheel 1 and the breast wheel 9, connect by driving-belt 82 between breast wheel 9 and the driven pulley 7.

Because the existence of breast wheel can be under the prerequisite that keeps the rotating ratio between driving wheel and the driven pulley, the size of effectively dwindling driving wheel has made things convenient for the structural design of elliptical machine.

In certain above-mentioned driving-belt one or two can be used gear drive instead.
