Abstract
The utility model discloses a bicycle power-assisted mechanism driven by compression springs, comprising a compression spring drive mechanism and bicycle pedals, wherein the compression spring drive mechanism comprises a fixed hood, steel sleeves, the compression springs, piston pressing sheets, connecting rods and a three-crank crankshaft; a plurality of steel sleeves are uniformly arranged on the circumference of the inner side face of the fixed hood; the compression springs are arranged in the steel sleeves; the piston pressing sheets are arranged on the compression springs; the connecting rods are fixedly arranged on the piston pressing sheets; the three-crank crankshaft comprises first crank journals, a second crank journal, third crank journals and main crank journals; the first crank journals, the second crank journal and the third crank journals are all parallel with the main crank journals; the eccentric distances of the first crank journals, the second crank journal and the third crank journals relative to the main crank journals are identical; the phase angle in the circumferential direction of the first crank journals, the second crank journal and the third crank journals relative to the main crank journals is 180 degrees; the connecting rods in the steel sleeves abut against the first crank journals, the second crank journal and the third crank journals; the main crank journals stretch out of the fixed hood and are connected with the bicycle pedals. The bicycle power-assisted mechanism driven by the compression springs is simple in structure, manpower can be saved, the fatigue can be reduced, the price is low, and the bicycle power-assisted mechanism is suitable for common people.
Description
Technical field
The utility model relates to a kind of rotary drive mechanism, relates in particular to a kind of rotary drive mechanism that Compress Spring is power of take.
Background technology
The driver train of bicycle has speed-changing mechanism usually, and usually when going up a slope, use significant effect is arranged, otherwise, due to reduction ratio being arranged, make the revolution of crank increase, the motion aggravation of pin, thus can not lessen fatigue at all.At present, with miniature electric motor and chargeable battery as the assistive drive means, it is loaded on car body, promote the car body walking for power-assisted, it is of a specified duration that but it has charging duration, once the travel distance of charging is short, battery is from great, the high in cost of production defect of working service, and the manually driven bicycle is in long distance, the occasion energy consumption of ramp and heavy burden is very large, be very easy to tired, in the pedal drive mechanism of bicycle and man, the firmly size of stretcher on the out of phase angle is unequal, when stretcher firmly maximum during in the highest or extreme lower position, firmly minimum while mediating, people ride in process, pedal force used all is not utilized, simultaneously, in the process of walking, when bicycle during in downhill running, potential energy is not used and wastes, in order to overcome the above problems, the applicant develops the boosting device for bicycle structure that a kind of Compress Spring drives, increased cheap elastic force auxiliary power unit on common bicycle.
The utility model content:
The purpose of this utility model is to provide the boosting device for bicycle structure that a kind of Compress Spring drives, it is simple in structure, can improve capacity usage ratio in manpower effect and downhill running, under identical condition, improve moving velocity at the manpower application force, reduce the force intensity of using in driving process, reduce people's sense of fatigue, use procedure is without increasing cost, economical and practical, is applicable to general public.
The boosting device for bicycle structure that a kind of Compress Spring drives, it is characterized in that: comprise Compress Spring driver train and bicycle pedal, bicycle pedal is separately positioned on the two ends of Compress Spring driver train, described Compress Spring driver train comprises fixed cover, steel bushing, Compress Spring, the piston compressing tablet, connecting rod and three-throw crankshaft, the medial surface even circumferential of described fixed cover arranges some steel bushings, Compress Spring is arranged in steel bushing, the piston compressing tablet is set on Compress Spring, be fixed with connecting rod on the piston compressing tablet, described three-throw crankshaft comprises the first crank shaft journal, the second crank shaft journal, three-crankshaft neck and crank journal, the first crank shaft journal is all parallel with crank journal with the three-crankshaft neck with the second crank shaft journal, the first crank shaft journal, the second crank shaft journal is identical with respect to the eccentric throw of crank journal with the three-crankshaft neck, circumferential phase angle between the two is 180 °, the other end of connecting rod arrives to respectively the first crank shaft journal, on the second crank shaft journal or three-crankshaft neck, described crank journal stretches out respectively fixed cover and is connected with bicycle pedal.
The working process of the boosting device for bicycle structure that Compress Spring described in the utility model drives is as follows:
After manpower applies certain strength to bicycle pedal, the crank journal that now drives the Compress Spring driver train rotates, make the first crank shaft journal, the second crank shaft journal and three-crankshaft neck circumferential movement, drivening rod motion respectively, thereby make the piston compressing tablet move downward, the Compress Spring compression rebounds again, promotes the first crank shaft journal, the second crank shaft journal and three-crankshaft neck and repeatedly moves, thereby drive whole Compress Spring driver train persistent movement, now bicycle just has enough power.Such structure makes bicycle use very laborsaving, as long as to some power, just can impel it to continue running, saved greatly manpower, such structure can not produce any pollution yet, and more be conducive to service life of bicycle, and low price, can be received by ruck.
