Description
Technical field
The present invention relates to technical field of bicycles, and in particular to a kind of bicycle with overturning-preventing auxiliary balance wheel and its
Operating method.
Background technology
For child, learns cycling and need to undergo the arduous process of a comparison, cycled because learning at the beginning
When the sense of equilibrium is bad often falls down, cause to damage；And for the elderly, it is old because of the reasons such as vehicle condition complexity
People's reaction is too late and causes to fall down.
Invention content
In order to keep riding for bicycle more steady, the present invention provides a kind of bicycle with overturning-preventing auxiliary balance wheel
And its operating method, the child poor suitable for the sense of equilibrium or the elderly's rides.
In order to achieve the object of the present invention, the present invention, which adopts the following technical scheme that, is implemented：
A kind of bicycle with overturning-preventing auxiliary balance wheel, including vehicle frame and the trailing wheel for being longitudinally disposed at vehicle frame rear,
It is set to the front-wheel of steerable head, and the actuating unit that driving front-wheel and/or trailing wheel are rotated around wheel shaft, which is characterized in that
Also there is at least one motor, energy source device, gyro sensor, electronic control unit, electronic control unit difference
Monitor the energy supply of the bicycle body angle of inclination signal of gyro sensor induction, the operation for controlling motor, energy source device；
It is provided in the middle part of the vehicle frame by the auxiliary balance wheel of motor driving rotation, lifting, the auxiliary balance wheel wheel shaft
Central axis is parallel with bicycle front-rear direction, and in car body to the left or to the right inclined safe slant range, electronic control
Device control motor makes the tire of auxiliary balance wheel not contact to earth；When car body is tilted beyond safe slant range to the left or to the right, electricity
Sub- control device control motor makes auxiliary balance wheel rapid decrease contact to earth, and auxiliary wheel is revolved in the same direction around axial rotary inclined side
Turn that bicycle body is made to return just.
The motor includes lifting motor and electric rotating machine, and lifting motor drives the lifting of auxiliary balance wheel；Electric rotating
Machine driving auxiliary balance wheel is rotated around wheel shaft.
The auxiliary balance wheel is set to the near end of elevating lever, and the other end of elevating lever is telescopically arranged in vehicle frame
On, the lifting motor drives lifter rod lifting.
The motor further includes the front motor and/or rear motor as actuating unit, in the control of electronic control unit
Under, energy source device driving front motor and/or rear motor correspond to and front-wheel and/or trailing wheel are driven to be rotated around wheel shaft.
As preferred Safe Design Scheme, the safe slant range is 0.2 ° ~ 15 °.
As another preferred Safe Design Scheme, also there is the brake apparatus being electrically connected with electronic control unit, system
Under dynamic state, motor stops operating.
In order to ensure that the lasting supply of power, the energy source device are accumulator.
For the ease of control, the present invention also has and switch controlling device, and the switch controlling device is by controlling electricity
Sub- control device, to control running/stopping of energy source device, gyro sensor, motor.
In addition, the present invention also provides the operating method of the bicycle with overturning-preventing auxiliary balance wheel, including it is following
Step：
A. actuating unit driving front-wheel and/or trailing wheel rotate and bicycle are made to have certain travel speed, gyro sensors
Device incudes the angle of inclination of car body；
B. it in the case where meeting step a, is kept just if bicycle body is tilted to the left or to the right in safe slant range
Often running；
C. in the case where meeting step a, if bicycle body is tilted beyond safe slant range, gyro to the left or to the right
Instrument sensor passes signal to electronic control unit, electronic control unit control motor falls auxiliary balance wheel and is allowed to contact to earth,

D. in the case where meeting a and c, gyro sensor incudes tilting of car body angle change, and in bicycle weight
It is new to restore to inclined safe slant range and after continuing for some time, motor driving auxiliary balance wheel stop rotating and again on
Rise to the state that do not contact to earth；
E. in the case where meeting a or b or c, starting brake apparatus makes front-wheel and/or trailing wheel stop rotating around wheel shaft,
And signal is fed back into motor control assembly, leave the motor off operation.
The safe slant range is 0.2 ° ~ 15 °.
In order to enable bicycle body to be restored to as early as possible in safe slant range from heeling condition, bicycle body is tilted beyond peace
Full reclining range is bigger, and motor drives the rotating speed bigger of auxiliary balance wheel rotating Vortex, reversed torsion bigger.
The invention has the beneficial effects that the angle of inclination of bicycle is incuded by gyro sensor, and what is set inclines
Oblique safe slant range, when bicycle angle of inclination is more than safe slant range, gyro sensor tilts bicycle
The signal of angle feeds back to electronic control unit and controls motor, makes the auxiliary balance wheel being laterally arranged, and is tilted in bicycle body
To inclined side rotating Vortex under state, providing reversed torsion makes the fast quick-recovery of car body to inclined safe slant range, avoids
Bicycle body magnitude of inclination is excessive, and cyclist is made to fall down；Since auxiliary balance wheel will not rise go back to original position automatically whithin a period of time,
When left and right vehicle wheel tilts repeatedly, it is ensured that after auxiliary balance wheel can adjust bicycle angle to safe slant range, auxiliary balance
Wheel is raised up to state of not contacting to earth again, while ensuring that bicycle is not toppled over, the auxiliary balance wheel declined is avoided to influence voluntarily
The normal operation of car body.
