Abstract
The utility model discloses a semi-automatic cycle which can change the vibration force into the driving force, and is composed of a soft seat with a backrest, a soft seat bracket, a buffer, an arc gear rack, flywheels engaged with the gear rack, etc. When the cycle is vibrated, the soft seat is bounced upwards, which drives the gear rack to move upwards and drives the flywheels to run forward to provide assistant driving force for the cycle. The utility model saves labor and brings comfort for riding. The cycle can also use a pedal to drive a crank to run to reduce the height and volume of the cycle further, and has safe riding operation and easy operation.
Description
The utility model relates to bicycle, particularly a kind of semiautomatic bicycle that shaking force can be become propulsive effort.
Existing bicycle does not have other damping facility except that the vehicle seat bottom is provided with the damping spring, and the vibrations during driving are after buffering, and its shaking force is accepted by the cyclist.Vehicle seat and human body area of contact are less in addition, and the friction of the pressure of human body and human body and vehicle seat concentrates on the bottom of pelvis, and the force part is not felt well even pain.If merely vehicle seat is strengthened, two leg action are obstructed.The someone has designed a kind of vehicle seat with backrest for this reason, and axis is shifted to the front upper place of vehicle frame, makes when riding to feel comfortably cool, and has reduced the vehicle seat height, but the also not positive processing of vibrations masterpiece when riding of this car.
Shaking force when the purpose of this utility model is to provide the simple way of a kind of usefulness to ride changes the semiautomatic bicycle of propulsive effort into, and simultaneously, this car adopts the soft seat of backrest, has reduced the vehicle seat height, reduces the horizontal direction resistance, and it is comfortable to ride.
The utility model is achieved in that in the rear axle left side flywheel is set, the sprocket of flywheel changed into the flute profile of cylindrical wheel.An arc-shaped rack consistent with the flywheel flute profile is set, and the tooth bar two ends connect two tooth bar poles, and two tooth bar pole front ends intersect, and make tooth bar and connecting rod composition fan-shaped, in two tooth bar joinings bearing are set and link to each other with pivot shaft on the vehicle frame.The backrest soft seat is fixed on the soft seat support, and soft seat support front end links to each other with vehicle frame with bearing with bearing pin, between tooth bar and soft seat support bumper is set, and these energy disperser two ends link to each other with the tooth bar upper end with the soft seat support respectively.Multistage bumper is set, its two ends are linked to each other with the soft seat support near the rear axle position with vehicle frame respectively.Axis is located at position, vehicle frame front upper place.
Because this car adopts the soft seat of band backrest, axis moves to the vehicle frame front upper place, and the people can lean against when riding on the soft seat backrest, and human body and vehicle seat area of contact are big, and it is comfortable light to ride.Moving the horizontal direction resistance that makes human body in the foot suitably reduces.When vehicle body was given a shock, soft seat support up-and-down movement when the soft seat support pops up, affected the tooth bar upward movement, and tooth bar drives flywheel motion again, and like this, shaking force promptly becomes propulsive effort.Though this propulsive effort can not can play auxiliary cyclist's foot-driven effect independently for the bicycle operation, has increased propulsive effort, correspondingly plays laborsaving effect.This car can reduce the vehicle seat height when adopting trundle (as 20 inch wheels), be sitting on the soft seat bipod during parking and can step in ground safety and braking effect when increasing brake.
Be described further below in conjunction with accompanying drawing.
Accompanying drawing 1 is the semiautomatic bicycle left view.
In rear axle left side flywheel (16) is installed, sprocket is changed into and arc-shaped rack (15) ingear profile of tooth, arc-shaped rack (15) two ends connect tooth bar pole (14), and tooth bar pole intersection has bearing to be connected with pivot shaft (13) on the vehicle frame (1).Backrest soft seat (11) is fixed on the soft seat support (12), soft seat support (12) front portion adds bearing with bearing pin (10) and links to each other with vehicle frame, soft seat support (12) rear portion links to each other with arc-shaped rack (15) upper end with energy disperser (18), and energy disperser is the shock absorption device that spring is arranged in.Vehicle frame (1) rear portion becomes forked supporting rear axle to the trailing wheel place, link to each other with multistage bumper (17) between forked vehicle frame and soft seat support (12), respectively establishes one about this bumper.Axis (2) is located at vehicle frame (1) front upper part, and axis right side dress chain drum (3) is connected with rear axle right side flywheel with chain (4).Another program of the present utility model is: Middle axle crank (5) links to each other with connecting rod (6) with bearing pin, connecting rod (6) links to each other with spherical pair (7) or cylindrical pair with pedal (8), pedal (8) rear portion is established bearing and is linked to each other with the bearing pin (9) of bottom surface, vehicle frame middle part, respectively establishes one about pedal.The foot-operated moving pedal of people drives crank and chain drum running one on the other, drives bicycle and advances by chain, flywheel.The crank limitation of length that can not be subjected to the employing pedal structure reduces the height of car, dwindles the volume of car, is convenient to deposit.At the vehicle frame middle part bale handle (19) is set, provides convenience when going downstairs on the car for removing.
The utility model can not only be produced the semiautomatic bicycle series of products of the specification that varies in size. Can also transform existing bicycle, tricycle etc., compare with existing various bicycles, have when moving up (as above go downstairs etc.) convenient, account for and occupy a narrow space; Laborsaving when riding, comfortable, safety; With tooth bar shaking force is become the device of driving force, simple in structure, cost is low, and is easy to implement.
Claims (3)
