Abstract
A pedal power auxiliary device of a bicycle comprises a frame, two pedal plates, two crank shafts, a flywheel shaft, a chain wheel, a chain, and a rear axle member, wherein manpower used for stepping pedals are transmitted to a rear wheel shaft through the crank shafts, the flywheel shaft, the chain wheel and the chain, so as to drive a rear wheel to enable the bicycle to advance; a pedal is respectively arranged on the left side and the right side of the frame, the pedals are arranged at the lower parts of thighs of a rider in an up and down manner, each pedal is connected with a first rotating shaft through a pedal connection plate, one end of the first rotating shaft is connected with a second rotating shaft on the frame through a supporting rod, and the other end of the first rotating shaft is connected with a pedal connection plate through a pedal connection rod; the length of the pedal connection rod is adjustable; and the length of the supporting rod is adjustable. According to the utility model, the speed and the endurance of a riding bicycle can be enhanced, and the labor saving effect is saved.
Description
Technical field
The leg that the utility model relates to a kind of bicycle steps force assistance device, relates in particular to the leg pedal of new clothes on a kind of bicycle, shank power is transmitted in stretcher by rotating shaft, connecting rod produces power, drives the efficient and the endurance of bicycle with increase.
Background technology
General bicycle more has the function of motion concurrently except for the instrument of riding instead of walk, therefore receives popular liking deeply; And bicycle is to utilize foot-operated forcing on the pedal; Drive wheel with chain, become to making bicycle to advance, this kind is prone to cause the tired out of rider's thigh and Calf muscle for the mode of power; Not only can influence rider's endurance ability, more can influence rider's speed.
Because the thigh muscle group is one of the strongest muscle of human body, and be the basis of whole body strength, when trampling bicycle and make potential energy and change, if can suitably stress on back crowd's leg flesh, can alleviate the load of thigh flesh Alm meat; If use leg muscle, just can increase strength and efficient that potential energy changes, and then increase speed and the endurance that drives as kinetic energy.
The utility model content
The utility model technical problem underlying to be solved is, overcomes the above-mentioned defective that prior art exists, and provides a kind of leg of bicycle to step force assistance device, and its increase drives the speed and the endurance of bicycle, reaches the labour-saving effect.
The utility model solves the technical scheme that its technical matters adopted:
A kind of leg of bicycle steps force assistance device; Comprise vehicle frame, two stretchers, two cranks, flywheel shaft, sprocket wheel, chain, hind axle member; Wherein step on bicycle via crank, flywheel shaft, sprocket wheel and chain, be passed on the hind axle, drive trailing wheel bicycle is advanced with manpower; It is characterized in that: the vehicle frame left and right side is respectively established a leg pedal; This leg pedal is arranged on the bottom of rider's thigh with mode one on the other; Each leg pedal is to be connected with first rotating shaft with the leg pedal rod, and first rotating shaft, one end utilizes pole to be connected with second rotating shaft on the vehicle frame, end is connected with stretcher with the stretcher connecting rod in addition.
The leg of aforesaid bicycle steps force assistance device, and wherein the length of leg pedal rod is adjustable structure.
The leg of aforesaid bicycle steps force assistance device, and wherein the length of pole is adjustable structure.
The utility model is left and right each leg pedal of one of new clothes on general bicycle; This leg pedal is to utilize rotating shaft and connecting rod etc. to link structure; Mode one on the other is arranged on rider's thigh downside, and the kinetic energy that produces with thigh strength is passed on the stretcher of general bicycle, relends by crank, flywheel shaft, sprocket wheel and chain and is passed to hind axle generation kinetic energy; Drive the speed and the endurance of bicycle with increase, reach the labour-saving effect.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

The specific embodiment
See also Fig. 1 to shown in Figure 4, the leg of the utility model bicycle steps a preferred embodiment of force assistance device, and general bicycle is to comprise members such as vehicle frame 1, two stretchers 2,2 ', two cranks 3,3 ', flywheel shaft 4, sprocket wheel 5, chain 6, hind axle 7; When wherein bicycle drives, step on stretcher 2 via crank 3, flywheel shaft 4, sprocket wheel 5 and chain 6, be passed on the hind axle 7, drive trailing wheel bicycle is advanced with manpower.The utility model principal character is:
In sum, the leg of the utility model bicycle steps force assistance device, is in order to alleviate when driving bicycle; The sense tired out that thigh and Calf muscle produced is at the bicycle left and right side one leg pedal to be set respectively, and this leg pedal is positioned at the bottom of rider's thigh with mode one on the other; When thigh applies pressure to the intensity of leg pedal, can be passed to stretcher by rotating shaft and connecting rod, along with the up-down of stretcher; With increase kinetic energy, and then increase the efficient that drives and reach the labor-saving effect.The utility model is on structure design, use practicality and cost benefit; It is required to meet industry development fully, and the structure that is disclosed also is to have unprecedented innovation structure, has novelty, creativeness, practicality; The regulation that meets relevant novel patent requirement is so mention application in accordance with the law.
