In order to further understand the technical effects of the present invention, the following further analyzes with reference to fig. 5-11, taking fig. 5 and 6 as an example, the pitch angle of the walker is detected by an angle sensor, so as to determine the slope condition of the current driving road surface, the offset distance between the center of gravity of the seat and the supporting point under different slopes can be predetermined by combining the specific size parameters of the walker, as can be seen from fig. 5 and 6, under the condition that the slope is 30 °, the center of gravity of the wheelchair lags 442.22mm on an uphill slope, and is easy to tip backwards, and the center of gravity of the wheelchair is advanced 442.22mm on a downhill slope, and is easy to tip forwards, so that the wheelchair can be moved forwards or backwards by changing the steering direction of the position adjusting motor according to the installation direction of the position adjusting motor; as can be seen from the trigonometric analysis shown in fig. 7, when the center of gravity deviates 442.22mm, it can be overcome by adjusting the position of the seat, and in combination with the installation direction of the seat rail, it is necessary to verify that the rail moves 610.63 mm.
The distance that the wheelchair moves forward or backward along the guide rail can be detected through the displacement sensor, the signals of the angle sensor and the displacement sensor can be corrected in an earlier stage, the signals of the displacement sensor can be matched with the signals of the angle sensor and the signals of the corresponding wheelchair, the signals of the two paths of signals are compared through the voltage comparator, and the signals can be used as driving reference signals of the position adjusting motor.
Taking the circuit shown in fig. 4 as an example, when the angle sensor signal is greater than the displacement sensor signal, the voltage is relatively strong (the comparison amplifier) and outputs a high-level signal, the transistor Q1 is turned on, the relay K1 is powered on and works, the normally open switch of the relay K1 is closed, so that the position adjusting motor is powered on and rotates in the forward direction, the transistor Q2 is turned off, and the relay K2 maintains a normally open state; when the angle sensor signal is smaller than the displacement sensor signal, a voltage ratio is strong (a comparison amplifier) outputs a low level signal, a triode Q1 is disconnected, the current of a relay K1 is blocked, the switch maintains a normally open state, a triode Q2 is closed, a relay K2 is powered on to work, the normally open switch of a relay K2 is closed, so that a position adjusting motor is powered on to rotate reversely, the forward and reverse rotation of the position adjusting motor drives the wheelchair to move, when the two sensor voltages are basically equal, the motor stops rotating, a seat is locked, so that the angle sensor signal and the displacement sensor signal maintain dynamic balance, finally terrain self-adaptive adjustment of the wheelchair position of the scooter is realized, and the position of the adjusted wheelchair is as shown in figures 8 and 9, no matter whether the wheelchair is on an uphill slope or a downhill slope, the gravity center of the wheelchair can basically coincide with the center point of the chassis support position.
Similarly, when going upstairs and downstairs, the control mode is the same as that of going upstairs and downstairs, specifically, as shown in fig. 10 and 11, by detecting the inclination angle of the vehicle body when going upstairs and downstairs, and by changing the position of the seat, the gravity center of the seat can be coincided with the chassis support midpoint or be in the preset range of the support midpoint, so that the phenomenon that the seat is overturned due to the deviation of the gravity center is effectively prevented.
In conclusion, the invention provides the all-terrain scooter and the control system thereof, which have the advantages of simple structure and convenience in control, and the gravity center of the scooter is adjusted by changing the position of the wheelchair, so that terrain self-adaption is realized, and the safety performance of the scooter is improved.
