Description

The infinite speed variation Electrical Bicycle

The utility model relates to a kind of Electrical Bicycle, especially a kind of infinite speed variation Electrical Bicycle.

As its name suggests, so-called Electrical Bicycle that is electric powerplant is set on the car body of bicycle can solves and substitute manpower and order about the problem that bicycle is advanced, example in this respect is of common occurrence on many public publications.Relatively be typically Chinese patent CN2175176Y, it has introduced the utility model patent that a kind of denomination of invention is an Electrical Bicycle.This patent is to have proposed a kind of new practical purpose technical scheme that is applicable on the basis of research more similar " electronic, pedal double-purpose bicycle ", " electronic assistive drive bicycle ".But the principal feature of this scheme is to install a driven sprocket on bicycle rear shaft additional, and is connected with driving chain between driven sprocket and the drive sprocket, and electrical motor, retarder, storage battery all are placed on the rear bicycle frame.Obviously, technique scheme mainly is that the action by electric installation drives bicycle rear axle and driven sprocket, drive sprocket, chain work, and its inventive point is that fasten the pass of dropping on " wheel " and " chain ".

Also has a kind of Chinese patent CN2180581Y " bicycle of drive driving machine ", its technical scheme drops on power-driven mechanism is installed on the back end support of bicycle, this mechanism mainly is made up of driving engine, retarder and chain-driving, if when selecting the power driven mode to ride, then want start the engine, the power of engine power footpath coupler, power drive sprocket, chain and band overriding clutch is delivered on the rear axle by movable sprocket, drive rear axle and on rear wheel movement, the bicycle ahead running.Be not difficult to find out that the inventive point of this technical scheme remains and drops on the active chain rivet.The Korean Patent that a kind of what is called " car of riding backwards " arranged again, this patent are the technical schemes of " the super gear transmission " that adopt, pedal before can making by bike people no matter be or after when scrunching, bicycle but always travels forward.The inventive point of this patent remains on the problem that drops on the gear rotation.

The purpose of this utility model is to provide a kind of infinite speed variation battery-driven car, it is the once big improvement on existing electric bicycle structure, especially the parts by transmission device are directly done face with the tire surface of the trailing wheel of bicycle or front-wheel and are contacted the packaging type transmission, thereby no matter be under power-actuated situation or the manually driven situation, all can reach clutch freely, the purpose of power maximum.

The purpose of this utility model is achieved in that a kind of infinite speed variation electric bike, it comprises and which is provided with stepless speed adjusting gear (11), battery capacity meter (15), battery scale (16), the travel bicycle handle bar (10) of gear (17) of manpower, have its internal configurations high-energy battery (12), circuit card (13), the wheel (32) of the infinite speed variation actuator (5) of coaxial motor (3), it is characterized in that described infinite speed variation actuator (5), between the two side driving device steel bracket (1) is set in its casing, left side in steel bracket (1), respectively offer an aperture on the right wall, the keyhole (6) that the position, hole is identical, described coaxial motor (3) is respectively established a clips (7) in the upper end of two motors about it, and by running through this clips (7), the motor fix shaft (2) of keyhole (6) is positioned at coaxial motor (3) on the described steel bracket (1); Respectively offer a concentric shafts sliding rail groove (8) on the left and right sides wall of described driving device steel bracket (1), and the concentric shafts (9) of coaxial motor (3) runs through one that tooth is unidirectional to take off post (4), and the two ends of concentric shafts (9) are inserted in the concentric shafts sliding rail groove (8).When coaxial motor is switched on, be installed on the motor shaft have tooth to move on taking off post and its cylinder does " face contacts packaging type " with tire surface thus transmission drives the bicycle forward movement.

Since adopted in above-mentioned technical scheme, especially the infinite speed variation actuator the design of driving device, make the utility model very significant advantage be arranged than traditional Electrical Bicycle:

1), the integral structure of bicycle need not to change, the infinite speed variation actuator can establish one's own system, have simple in structure, install easily, convenient carrying:

2), be installed in and have tooth transmission iron prop only to do face to contact the packaging type transmission, greatly effectively raise powerdriven efficient on the coaxial motor with the tyre surface of wheel;

3), the setting up of concentric shafts sliding rail groove, the unidirectional employing that takes off post has realized its pair clutch action, it is very nimble to make that electric power and manpower drive the mutual conversion of bicycle, not only can laborsaving driving but also can do the body-building motion.
