Description
Technical field
The utility model is related to bicycle art, patent classification B62K more particularly to a kind of overlength are ridden and are stepped on up and down
Step on formula labour-saving bicycle.
Background technology
Existing ordinary bicycle is mostly to replace pedal by both legs to realize movement, and left and right both feet, which alternately are stepped on to pedal, to be also caused
Firmly imbalance, both hands can only be accomplished to hold direction and brake and assistance balance transient state.Bicycle in daily life
Driving device be all convolution pedal-type, both feet alternately step on the mechanism pedaled such as toggle, generate upper and lower two it is dead
Point, thus can not continuous doing work, the disadvantages such as there is driving transformation efficiency be low.Position relationship between pedal rod and sprocket wheel axis
When perpendicular to ground, left and right foot, which scrunches downwards, cannot generate driving force, only when the position between pedal rod and sprocket wheel axis
When at horizontal relationship, driving force could be generated to the greatest extent.
Ride is wanted to accelerate to ride or encounter uphill way, and bicyclist, which is usually forced to stand, to ride, and uses own wt
It acts on and increases driving force on bicycle pedal.But that foot that whole body is stood downwards firmly always directly runs to minimum
Dead-centre position in place can not stop；Therefore, another foot also can only cause both legs to hold very much in highest dead point relay
It is easily tired out, cannot be lasting, and it is not suitable for daily ride.
Quickly, laborsaving ride is central factor that people consider in go off daily, for this purpose, there is technical solution to be provided with set
Button bicycle pedal overcomes the defect of upper bottom dead centre, allows the foot of bicyclist can be close to pedal in any position of circumference
Plate, such as granted patent number： 201020300738.7；Although buckle bicycle pedal solves the problems, such as being bonded for foot and pedal,
But there is no substantially solution convolutions to scrunch the laborious disadvantage of mechanism, while when having a car accident, people's vehicle is difficult to detach, and causes to ride
Row increased risk.Circular chain-wheel is designed as ellipse, such as granted patent number by somebody：201280041248.1 bicycle
Asymmetric elliptical chain gear, etc. all be painstakingly improvement bicycle improve speed.In order to allow both hands also can be to double
Foot a helping hand, someone by the hand-operated mechanism of disabled person on bicycle, such as the one of 9,056,653 B2 of United States Patent (USP) US
The bicycle Hand-foot compound bicycle with double ratchet of kind of compound double ratchet wheels of brothers, it is hand
Mechanism brings left and right unstable, and still could not solve convolution pedal-type bicycle and necessarily lead to consolidating for upper and lower two dead points
There is drawback.
Utility model content
The utility model proposes a kind of overlength bicycle based on lever principle, to overcome traditional Clothoid type voluntarily
Vehicle disadvantage laborious in daily ride, particular content are as follows：
The technical solution of the utility model is：A kind of long bicycle, including vehicle frame, driving mechanism and wheel group；It is special
Sign is：Vehicle frame is made of plug connecting tube, double-axle sleeve connecting tube, vehicle frame upper rack posts, vehicle frame lower fulcrum bar, and plug connecting tube is fixed
In double-axle sleeve connecting tube, double-axle sleeve connecting tube is equipped with foot-operated axis axle sleeve and chain wheel axis axle sleeve；In double-axle sleeve connecting rod, vehicle frame
Strut, vehicle frame lower fulcrum bar, which interconnect, to be fixed；
Driving mechanism includes that overlength rides group, connection rod set, crank throw, chain wheel, flywheel；The foot-operated group of overlength includes two overlength feet
It steps on, connection rod set includes two connecting rods, and the foot-operated top of each overlength is set there are two branch joint, and two branch joints are separately connected foot
Axis and a connecting rod are stepped on, two connecting rods, which are divided into, not to be connect with crank throw and chain wheel；Chain wheel is connected chain in a manner of engaging
Drive flywheel；
Foot-operated axis is connected and fixed on foot-operated axis axle sleeve, and crank throw and chain wheel are connected and fixed on by chain wheel axis in chain wheel
Axis axle sleeve.
The plug connecting tube can be mounted on double-axle sleeve connection tube end or middle section.
Double-axle sleeve connecting tube can be linearly after being connected with vehicle frame lower fulcrum bar, also can oblique connection form bending, angle is curved
Bent angle can be at 80 ° -180 °.
What the overlength was ridden steps on brachium in ordinary bicycle, can reach 20-120CM, and step on arm and be linearly bent
Shape, bending angle is up to 90 ° -170 °.When assembling, overlength is ridden branch joint and is connected and fixed towards ground.
The chain wheel includes chain wheel pedestal and chain wheel main body, and chain wheel pedestal is equipped with round edge rectangle axis hole, and by fastening spiral shell
Silk is connected and fixed to form one with chain wheel main body.
The overlength bicycle is equipped with double plate brake, disc brake and wheel and stops, and is used for vehicle body braking.
It is additionally provided with external screw thread packing washer on the chain wheel axis axle sleeve.
The bicycle further includes schoolbag frame, mud guard, vehicle seat, and is connect respectively with vehicle frame.
It is further described that when the foot-operated effect downwards of overlength, connecting rod, connecting rod is pulled to pull crank throw, make chain wheel axis and tooth
Disk rotates, and chain wheel drives chain, pulls rear flywheel rotation.Crank throw on chain wheel pulls connecting rod, makes another overlength is foot-operated to make upwards
With.
