Detailed description of the invention
Referring to Fig. 1, Fig. 2, the present invention includes pedal tread 1, pedal arm 10, drives motor 8, drive mechanism and operating-controlling mechanism.Driving motor and drive mechanism to be arranged on pedal arm, operating-controlling mechanism is arranged at the console of driver's cabin.Controlled to drive electric machine rotation by operating-controlling mechanism, drive motor drive transmission device action, thus realize the pedal tread angle adjustment relative to pedal arm.
Referring still to Fig. 1, Fig. 2, drive mechanism includes worm screw 5, worm gear 3, pedal tread bracing frame 2 and rotary shaft 4.Worm screw is connected through shaft coupling 7 with driving motor output shaft, and shaft coupling is selected to be had elastic damping, noiseless, be not required to lubrication, diaphragm coupling that transmission accuracy is high.Worm screw, worm gear engage each other connection, and pedal tread bracing frame is welded and fixed with pedal tread, drive institute's pedal tread synchronous axial system when pedal tread bracing frame rotates.Described rotary shaft 4 sequentially passes through worm gear, pedal tread bracing frame and pedal arm, and the side of rotary shaft is fixed circumferentially through flat key 14 and worm gear, pedal tread supporting framework and is connected, and rotary shaft opposite side constitutes hinged with pedal arm.Described drive mechanism utilizes Worm Wheel System, the direction of transfer of moment of torsion can not only be changed, and there is reverse self-locking function, i.e. can only be passed to worm gear by worm screw by the moment of torsion driving motor to transmit out, and worm gear cannot rotate by reverse drive worm screw, therefore can carry out locked to the gas pedal face angle after adjusting, when preventing driver pushes pedals face, pedal tread causes pedal tread automatically to rotate because of stress, departs from set angle and causes failure of adjustment.Stable for ensureing worm gear, worm movement, set up worm screw support set 6, worm screw support set is fixed with pedal arm, and the bar portion of worm screw passes worm screw support set and worm screw support set matched in clearance.Drive motor 8 to be fixed on driving electric machine support 9, drive electric machine support to fix with pedal arm 10, drive motor to select stepper drive motors,
Referring to Fig. 1, operating-controlling mechanism includes CPU11, angular transducer 13 and instrument board 12, and angular transducer is arranged on pedal tread back, and the pedal tread angle signal of collection is delivered to CPU by circuit by angular transducer；CPU line road connects instrument board, the integrated LCDs of instrument board, and CPU accepts button regulation signal, controls to drive motor to rotate forward or backwards.
Referring to Fig. 3, the operation principle of operating-controlling mechanism is as follows: driver is the most comfortable by first examination pedal subjective feeling pedal tread angle, when feeling that angle causes foot uncomfortable, LCDs button on adjusting apparatus dash board, CPU is by accepting instrument board touch key-press regulation signal, it is converted into pulse signal through signal processing and passes to stepper drive motors, control to drive motor to rotate forward or backwards, motor output torque is driven to pass to drive mechanism by shaft coupling, worm gear wheel also drives pedal tread fine setting through pedal tread bracing frame, thus gradually it is adjusted to pedal tread to the work angle of the most comfortable.
Referring to Fig. 4, the workflow of the present invention is as follows: in the case of vehicle is energized, driver tramples gas pedal Mian Shi subjective feeling foot angle sensation, as uncomfortable, by adjusting the touch key-press on instrument board liquid crystal display, after CPU control unit receives key information, carry out signal processing and be converted to stepper drive motors electronic pulse signal applicatory, stepper drive motors receives the pulse signal that microprocessor sends, rotate forward according to pulse signature messages or invert, stepper drive motors can control according to pulse signal to rotate the number of turns accurately, carry out accurate transmission, during pulse-free signal input, servo drive motor will not rotate.The torque of servo drive motor is transferred to worm screw through diaphragm coupling, drives worm screw to rotate, worm gear wheel under the drive of worm screw, and worm gear wheel drives rotary shaft to rotate, and rotary shaft drives pedal tread bracing frame to rotate, thus realizes the angle adjustment in gas pedal face.The angle detecting sensor that pedal tread back is arranged, it is possible to be accurately detected the pedal tread angle of vehicle on level road, is transmitted by the signal of angular transducer, can clearly demonstrate pedal tread angle and store in dashboard displays.When different drivers drive vehicle cause accelerator pedal angle to change time, vehicle owner can accurately give the angle that early stage has set for change, and whole adjustment system quits work after angle adjustment completes.
