With rechargeable battery 94, which is provided with power source charges interface 93.The power supply of controlled motor 2 is using portable charge power supply or vehicle-mounted
Formula power generating source.
In the present embodiment, controlled motor 2 is several rotary electric machines being installed in internal speed changer housing, rotary electric machine
Correspond with gearshift control bar；Referring specifically to Fig. 2, taking axle control control bar 11 as a example, rotary electric machine passes through screw drive mechanism
It is connected with axle control control bar 11, the screw rod 22 of screw drive mechanism is connected with the clutch end of rotary electric machine, axle control control bar
It is fixed with nut 112 on 11 to threaded with screw rod 22, positive and negative rotation is converted into by controlled motor 2 by screw drive mechanism
Linear motion impeller-hub control control bar 11 axially moves back and forth.It is additionally provided with gearshift control bar gear positions anti-in automatic internal speed variator of real
Feedback unit, including the parallel location-plate 15 being installed in gearshift control bar one end, location-plate 15 is provided with and corresponding gearshift control vertically
Bar axial direction gear positions corresponding control bar position sensor 151 processed, control bar position sensor 151 adopts proximity switch to detect
The position of nut 112, and connected to the control module of controller by the input module that communicates, in the process of controlled motor variable block
In, if after the gearshift gear of axle control control bar puts in place, control bar position sensor 151 feedback signal, to control module, controls
Module controls controlled motor to stop, and realizes being accurately positioned of gearshift.In addition the middle control control bar 12 in internal speed changer is also to adopt
Identical scheme.
In conjunction with referring to Fig. 3 to Fig. 5, the signal gathering unit of controller 9 includes manual shift switch 95, the speed of detection speed
Degree sensor 3, detection scrunch the torque sensor 4 of moment and the crank position sensor 5 of detection crank position, wherein, handss
Move position switch 95 to be arranged on controller housing body, velocity sensor 3 is arranged on the front vehicle wheel of bicycle, torque sensor
4 Wu Tongchu being arranged on bicycle, crank position sensor 5 is arranged on the vertical tube of cycle frame, crank position sensor 5
Gather the turned position of crank, referring specifically to Fig. 5, during cycling, by scrunching, crank 6 using proximity switch
Drive driving gear disc 7 to rotate, when crank 6 is located at top or lowermost end, be the transition period that two foot exchanges are had an effect, now
The moment that crank is subject to is minimum, therefore at this moment internal speed changer is shifted gears, and suffered impact is minimum.
Manual shift switch is directly connected by wired electric signal communication module between control module input, i.e. electric wire
Connect；Pass through between velocity sensor and control module input and between torque sensor and control module input wired
Electrical signal communication module connects, and also can be connected by wireless communication module, wherein velocity sensor and torque sensor are provided with letter
Number emitter, control module input is provided with signal receiver.The concrete scheme of wireless communication module refer to existing voluntarily
Vehicle radio code table.
In the present embodiment, the output signal module between the control module outfan of controller 9 and motor control terminal with
And the input signal module between the control module input of control bar position sensor 151 and controller is to adopt line telecommunications
The control electric wire 21 of signal communication module is realized connecting, and preferably other schemes also can be connected by wireless communication module, by setting
Put signal projector and signal receiver, internal speed changer can be set to full-closed structure.
Control module is one of DSP, ARM, PLC or single-chip microcomputer, using common model general is on the market specifically
Can.
The method for changing speed of the automatic internal speed variator of real of the present embodiment includes following Three models：
A) automatic mode.Referring to Fig. 9 and Figure 12, the riding speed of controller Negotiation speed sensor feedback and control module
The gear speed of interior setting is contrasted, and in upshift process (speed lifting), seven gears correspond to seven upshift speed, ride
After speed exceedes the upshift speed of corresponding gear, controller controls the controlled motor within internal speed changer to manipulate gearshift control bar liter
Gear, likewise, in downshift process (speed reduction), seven gears equally correspond to seven downshift speed, when riding speed is less than
After the downshift speed that corresponding gear sets, controller controls the controlled motor within internal speed changer to manipulate gearshift control bar downshift,
Referring specifically to Figure 12, in order to avoid, in ride, riding speed causes fluid drive when same velocity node fluctuates
The frequent ascending, descending of device keeps off, and in described automatic mode and motor pattern, the upshift speed (in figure realization) that each gear sets should
More than downshift speed (in figure dotted line).
Meanwhile, the conversion of gear can be intervened in automatic mode using manual shift switch manual, do manually in first time
After pre- gearshift, if control module does not receive the signal of manual shift within the time setting again, automatically return to certainly
Carry out variable block under dynamic model formula, so, during the riding of different road conditions, can be carried out manually according to the muscle power of different bicyclists
Adjustment, such as during climbing, the such as not good bicyclist of muscle power, can the lower gear of quick manual adjustment realize riding steady
Qualitative, delay is had with the variable block that the rapid drawdown preventing riding speed during climbing leads to internal speed changer, causes of short duration high gear
The situation that low speed exists, bicyclist's shakiness of therefore riding leads to fall car.
B) motor pattern.Referring to Figure 10, in automatic mode, increase the detection to the crank moment in ride, when
Exceed when scrunching moment of setting, controller is thought that bicyclist is intended to have an effect and accelerated, now control within internal speed changer
Controlled motor manipulates gearshift control bar and rises to top gear, quickly to improve riding speed.
C) manual mode.Referring to Figure 11, the controller manually control within shift switch Non-follow control internal speed changer
Motor manipulates gearshift control bar and carries out upshift or downshift.Wherein, referring to Fig. 6, its upshift and downshift are equal for MTS 95
Including two contact switch KM1/KM1 ', KM2/KM2 ' in parallel, MTS short distance up or down promotes, you can
Rise a gear or one gear of fall, distance promotes up or down, you can once rise two gears or two gears of fall, carry
High quick variable block efficiency in particular cases.
Automatic mode, motor pattern and manual mode are switched over by mode selector switch.
In automatic mode and motor pattern, controller controls the opportunity of gearshift when crank is located at least significant end or most significant end
Wait, or when scrunching the gearshift moment that moment is less than setting of crank, according to crank position sensor or torque sensor
The signal control motor gearshift of feedback.The stopping existing in conjunction with bicycle or the situation of go-cart, when torque sensor is zero, that is,
Bicycle is made to there is the change (i.e. go-cart process) of speed, automatic mode and motor pattern all stop automatic shifting；Pass in speed
Sensor is when zero (docking process), and controller controls the controlled motor within internal speed changer to be converted into starting gear, described
Step gear may be set to the random shift of internal speed changer.The starting gear of bicycle is different from automobile, and minimum gear is unfavorable on the contrary
Ride in starting, therefore starting gear can preferably in the middle of gear low in gear, 2,3,4 gears such as in seven speed transmission,
So that the speed Rapid matching after starting of riding is to the variable block speed of corresponding gear.
