Description

A kind of autoamtic boosting bicycle

The utility model relates to the bicycle field, especially a kind of autoamtic boosting bicycle.

As everyone knows, bicycle is a kind of running vehicle very easily.The existing so far very long history of development, bicycle produces vibrations always in the process of riding usually, also is like this even ride on smooth road.People are provided with damping spring under saddle for this reason, and rider's health also is compression and the stretching, extension with the damping spring of saddle like this, heave and set, though amplitude of vibration alleviates to some extent, vibrations also are very big, as riding on very not smooth road surface, this shaking force is just bigger, and the people is not felt quite oneself.People have developed a kind of Bicycl with booster (as Chinese patent CN85100785.A number) again in the recent period, and this bicycle is the shaking force that utilizes in the process of riding, and is transformed into the auxilliary power that adds that bicycle moves ahead automatically, makes the rider laborsaving comfortable.This technology is that a gear acceleration gearbox is fixed on the back shelf of bicycle, be fixed with a flat steel pipe (claiming the saddle lever) on the input shaft of change-speed box, bicycle saddle is installed in the other end of saddle lever, a small flywheel sheet is installed on the output shaft of change-speed box and is linked to each other with the left side flywheel (flywheel of An Zhuaning separately) of bicycle rear by cycle chain, simultaneously, the bicycle acceleration gearbox input shaft other end and a recoil spring join, and (this spring can be the disc plane spring, extension spring or stage clip) so that play equilibrium activity.Because this technical pattern design is unreasonable, structure is complicated, influences its service life, and the use of influence back shelf, does not apply so see it so far.

The utility model is at the situation of prior art, designs a kind of simple in structurely, reasonable in design, easy to use, do not influence the functions of use of bicycle itself, can alleviate vibrations, the labour-saving autoamtic boosting bicycle of riding.

The utility model is achieved by following manner: a kind of autoamtic boosting bicycle, comprise vehicle frame and front and back wheel thereof etc., it is characterized in that: on the back wheel location of vehicle frame motor-driven assistor is set, this device partly is made of shock absorbing part, conversion portion, running part, clutch.Wherein, the left side that the shock absorbing part upper and lower end is connected with bicycle saddle and hind axle respectively, conversion, transmission and clutch partly are positioned at bicycle rear and shock absorbing part thereof, and the transmission gear setting of the conversion flywheel of conversion portion and running part and being fixed on the same axle.

Said shock absorbing part is made up of sleeve that is symmetricly set on vehicle frame trailing wheel place and interior damping spring thereof, wherein the lower end of two damping springs is fixed on the two ends of hind axle, the sleeve upper end is connected with bicycle saddle, here shock absorbing part has the double action of damping and energy storage, the people produces the pressure that a size constantly changes to damping spring in riding, damping spring is compressed distortion when pressure increases, stored energy, vehicle body descend (here because vehicle frame trailing wheel bottom is due to the movable axis) simultaneously, spring was stretched out and is released energy when pressure reduced, the promotion vehicle frame rises, therefore this bicycle is in the process of riding, and the up-and-down movement of its vehicle frame (or claiming vehicle body) is continuously.

Said conversion portion by the vehicle frame that is arranged on sleeve and damping spring thereof left side after the rectangle chain fork of wheel location and the left side on both sides thereof, right chain, and with a left side, two conversion flywheels of right chain fit engagement are formed, wherein changing flywheel captives joint with transmission gear by axle, promptly changing flywheel and transmission gear is fixed on the same axle at a distance of certain distance, rectangle chain fork connects to ground, be connected with sleeve again, rectangle chain fork moves up and down with vehicle body when riding like this, drive the conversion flywheel and make anticlockwise motion, when specifically being vehicle body decline, rectangle chain fork moves downward, left chain on it drives a conversion flywheel and makes anticlockwise motion, corresponding transmission gear is also made anticlockwise motion, right chain then drives another conversion flywheel and does clockwise direction idle running at this moment, when vehicle body rises, rectangle chain fork upward movement, right chain drives another conversion flywheel that advances and makes anticlockwise motion, corresponding transmission gear is also made anticlockwise motion, left chain then drives a conversion flywheel and does clockwise direction idle running, like this vehicle body up-and-down movement once, two conversion flywheels just replace makes anticlockwise direction each rotates once.

Said running part by and the conversion flywheel be installed in transmission gear, the driving flywheel that is arranged on hind axle left side and a servodrive chain between transmission gear and driving flywheel on the axle and form, transmission gear and drive flywheel and coexist on the vertical plane surface wherein, here the hind axle left side is for driving flywheel, its right side then is the miniature gears of normal bicycle, when riding, the conversion flywheel is made anticlockwise motion and drives transmission gear to rotate synchronously, drive by the servodrive chain and drive the flywheel rotation this moment, drives bicycle and move ahead.Reached the purpose of autoamtic boosting (will be very laborsaving like this).

Said clutch part by be arranged on handle and backguy thereof on the skew girder of vehicle frame, difference is pulled out in clutch and retracing spring is formed, wherein change flywheel and transmission gear and be by two pins on the conversion flywheel being set and being arranged at two the pin-and-holes dos insertion on the transmission gear or the flexible connection of extracting realizes clutch.

The utility model is compared with prior art, has simple in structurely, reasonable in design, do not influence and ride, and it is laborsaving to ride, and shakes characteristics such as little.

Fig. 1 is an overall structure scheme drawing of the present utility model;

Fig. 2 is the partial enlarged drawing of motor-driven assistor of the present utility model;

Fig. 3 is the principle of work sketch of autoamtic boosting of the present utility model.

Among the figure: 1 vehicle frame, 2 chains fork, 3 sleeves, 4 damping springs, 5 trailing wheels, 6 drive flywheel, 7 conversion flywheels, 8 transmission gears, 9 foot-operated chains, 10 bicycle gears, 11 stretchers, 12 movable axis, 13 handles, 14 bicycle ladders, 15 clutch forks, 16 left chains, 17 servodrive chains, 18 backguys, 19 hind axles, 20,21 right chains.

Most preferred embodiment of the present utility model, as Figure 1-3, a kind of autoamtic boosting bicycle comprises vehicle frame 1 and front and back wheel thereof etc., it is characterized in that: on trailing wheel 5 positions of vehicle frame 1 motor-driven assistor is set, this device partly is made of shock absorbing part, conversion portion, running part, clutch.Wherein, the left side that the shock absorbing part upper and lower end is connected with bicycle saddle and hind axle respectively, conversion, transmission and clutch partly are positioned at bicycle rear and shock absorbing part thereof, and the transmission gear 8 of the conversion flywheel 7 of conversion portion and running part is provided with and is fixed on the same axle.
