Abstract
The invention provides an electric control device of a semi-automatic folding electric power assisting cycle, which can realize automatic unfolding of a frame and has labor-saving, fast, convenient and safe use. The electric control device comprises a three-phase brushless direct-current motor, a micro-controller and a switch, wherein the three-phase brushless direct-current motor is installed at a rear wheel; the switch is installed at the frame; when the frame in a folded state needs to be unfolded, the switch transmits signals to the micro-controller to control the three-phase brushless direct-current motor to drive the rear wheel to rotate reversely at a fixed distance; and when the frame in an unfolded state needs to drive, a speed-regulating handle controls the rear wheel to rotate forward by the micro-controller so as to control drive the cycle to run.
Description
(1) technical field
The present invention relates to the moped technical field, be specially a kind of electric control device of semi-automatic folding electric power assisting cycle.
(2) background technology
Existing folding bicycle, it comprises vehicle frame, assembly, front-wheel, the trailing wheel with expansion and folder function, the electric-control system that is arranged on the saddle on the vehicle frame and drives front-wheel or trailing wheel.For the ease of carrying, reduce memory space, existing folding bicycle, its vehicle frame adopts one or more foldable structure, realizes folder function, and launch its folding back is to pull pine by dependent manual operation, relatively require great effort, especially in summer, the user generally wears the footwear that reveal toe, folding car is opened and need be cooperated with pin, and just very inconvenience overexerts and can hinder utmost point toe, fail safe is bad, firmly kick the beam, be difficult for again opening, use effort, also inconvenience.
(3) summary of the invention
At above-mentioned technological deficiency, the invention provides a kind of electric control device of semi-automatic folding electric power assisting cycle, it can realize vehicle frame to launch automatically, uses laborsaving, fast, convenient and safe.
Its technical scheme is such: it comprises three-phase direct-current brushless motor, microcontroller, switch, described three-phase direct-current brushless motor is installed on trailing wheel, described switch is installed on vehicle frame, it is characterized in that: when vehicle frame was in folded state and need opens, switch passed to the reversing of microprocessor controls three-phase direct-current brushless motor-driven trailing wheel spacing with signal; When vehicle frame is in deployed condition and need travels, speed-regulating handle bar by the microprocessor controls trailing wheel forward the rotating drive car travel.
It is further characterized in that: described electric-control system also comprises power driving circuit, current sampling circuit, and speed-regulating handle bar speed-regulating signal circuit is connected with the input I/O mouth of microcontroller with counter-rotating triggering signal circuit; Three road PWM output of microcontroller is through power driving circuit rear drive machine operation; The operating current of current sampling circuit sampling motor also inputs to the analog-to-digital conversion interface ADC of microcontroller; Motor rotor position detection signal (A phase, B phase and C are mutually) inputs to the input I/O mouth of microcontroller respectively.
The present invention is used for vehicle using motor, and when launching transition, reverse by controller controlling and driving motor spacing from folding for vehicle frame, thereby realize car from folding to launching quick transition, laborsaving, quick and easy, so just need not launch by foot's strength, fail safe is higher.
(4) description of drawings
Fig. 1 is a block diagram of the present invention.
(5) embodiment
See Fig. 1, the present invention includes and comprise three-phase direct-current brushless motor 3, microcontroller 1, switch, power driving circuit 2, current sampling circuit 4, three-phase direct-current brushless motor 3 is installed on the trailing wheel (not expressing among Fig. 1) of car, and speed governing hall signal circuit is connected with the input I/O mouth of microcontroller 1 with counter-rotating triggering signal circuit; Three road PWM output of microcontroller is through 3 work of power driving circuit rear drive motor; The operating current of current sampling circuit sampling motor also inputs to the analog-to-digital conversion interface ADC of microcontroller; Motor rotor position detection signal (A phase, B phase and C are mutually) inputs to the input I/O mouth of microcontroller respectively.When vehicle frame is in folded state, when needing to launch, switch passes to microcontroller 1 control three-phase direct-current brushless motor 3 with signal and drives the reversing of trailing wheel spacing, after vehicle frame is in deployed condition, speed-regulating handle bar by microcontroller 1 control trailing wheel rotating drive car travel speed-regulating handle bar and microcontroller 1 between annexation, the genus prior art.
In whole folding and expansion process, the work of whole electric-control system is as follows:
Step 1: when electric motor bicycle with folding launched, actuating switch (do not express among the figure, decided according to body frame structure for automotive, as long as switch and microcontroller electricly connect, provides the counter-rotating triggering signal by the particular location of switch.
Step 2: microcontroller determines the counter-rotating triggering signal when effective, changes the phase sequence of output PWM, makes motor backward rotation (clockwise), rotates one and stops after enclosing; At this moment, car is by folding to the deployed condition transition;
Step 3: controller returns to the positive revolving die formula (counterclockwise) of acquiescence.
Step 4: in the motor Umklapp process, judge the motor working current that sampling comes, carry out motor rotation blockage judgement and over current of motor and judge, microcontroller is carried out real-time rotation-clogging protection and overcurrent protection.
