Below in conjunction with description of drawings course of action of the present utility model:
Double-wheel self-balancing trolley as shown in Figure 1 is in traveling process, keeping the two-wheeled balance and be by accelerometer 38(model is the twin-axis accelerometer of MXP7205VF) and gyroscope 37(model be ADXRS610) signal that produces, pass to controller 34, the wheel hub motor 6(model that controller 34 passes to control signal the dolly both sides again is WY24V180W), wheel hub motor 6 can be with the frequency drives wheel 23 of per second 100 times, keep the car kinetic balance, guarantee that car can not fall down.
Shown in Fig. 2,3, dolly is turned to, chaufeur steering wheel rotation 24, bearing circle 24 drives upper deflecting bar 25 and rotates, it is the particularity increment type grating angular displacement sensor of ZL120 that upper deflecting bar 25 drives angular-motion transducer 30(model by spring card 28) produce angular displacement signal, and signal is passed to controller 34, controller 34 passes to control signal the wheel hub motor 6 of dolly both sides again, thereby change direction and the rotating speed of wheel 23, and then realize that car body turns to.After dolly turned to end, chaufeur unclamped bearing circle 24, and the moment of rotation that acts on this moment on the deflecting bar 25 disappears, and under the effect of deflecting bar retracing spring 29, deflecting bar 25 is resetted, and then bearing circle 24 is resetted.
As shown in Figure 4, dolly is advanced forward, chaufeur is by trampling the pedal 35 of advancing, the pedal 35 of advancing is turned forward, and be arranged on accelerometer 38 and the gyroscope 37 of pedal 35 inside of advancing this moment, can produce corresponding acceleration/accel, angular acceleration and speed signal, signal can pass to controller 34, controller 34 passes to control signal the wheel hub motor 6 of dolly both sides again, thereby regulates the rotating speed of wheel 23 and turn to, and realizes that dolly advances forward; Dolly is retreated advances, chaufeur is by trampling the pedal 35 of advancing, the pedal 35 of advancing is receded, be arranged on accelerometer 38 and the gyroscope 37 of pedal 35 inside of advancing this moment, can produce corresponding acceleration/accel, angular acceleration and speed signal, signal can pass to controller 34, and controller 34 passes to control signal the wheel hub motor 6 of dolly both sides again, thereby regulate the rotating speed of wheel 23 and turn to, realize that dolly retreats to advance.
As shown in Figure 5, in the dolly traveling process, as run into obstacle and cause tilting of car body excessive, perhaps outage is when (comprising brake outage or the outage of stopping), interior accelerometer 38 and the gyroscope 37 of dolly this moment can produce corresponding signal, and passes to controller 34, and controller 34 sends control signal and passes to the good board electric foldable wheel of baby that folding wheel 41(model is 612BW), folding wheel 41 can be fallen automatically, guarantees the stable of dolly; When dolly recovered steadily normally to travel, folding wheel 41 can be got back to the initial fold state.
Shown in Fig. 6,7, when dolly is braked, chaufeur is by trampling brake pedal 9, brake pedal 9 is moved downward, thereby driving outage bar 13 moves downward, the normally closed contact disconnection of cutting off the power supply this moment and forming between contact 36 and the switch plate 8 on the bar 13, cause wheel hub motor 6 outages, simultaneously brake pedal 9 is pump on the disc brake behind the cross-country car of CQR by brake pump 15(model) act on the disk type brake 16, disk type brake 16 acts on the wheel hub motor 6 that has cut off the power supply, make it deceleration until stop, the dolly braking is finished.This moment, chaufeur releasing of brake pedal 9, and under the effect of brake extension spring 7, brake pedal 9 resets, and under the effect of brake retracing spring 12, outage bar 13 resets.
As shown in Figure 8, in the dolly traveling process as run into the situation of Uneven road, wheel 23 can be delivered to connecting arm 17 by wheel hub motor 6 with pitch force, connecting arm 17 passes to pitch force bumper 22 again, consumption by bumper 22, reduce the impact that vehicle body 42 is subject to, play cushioning effect.
