On the described wheel drive motor is installed;
In the junction of described wheel and described car body three shaft inclination sensors are arranged, three shaft inclination sensors, control system also are installed on the described car body;
Described control system is connected with described incremental encoder, described three shaft inclination sensors, described three shaft inclination sensing data lines successively.
Car body, about the wheel, wheel drive motors, sensor assembly and the control system that distribute.For rotating shaft is connected, the shaft centerline of left and right wheels is located on the same line between wheel and the car body, is provided with for the platform that supports human body at car body, and car body can be around the shaft swing of wheel; Sensor assembly comprises wheel speed sensor and pose checking system; Storage or solidified the corresponding program that is used for the control balance in the control system circuit.The driver controls the running velocity of battery-driven car by self attitude adjustment, the signal that control system reception wheel speed sensor and pose checking system are imported, go out the needed control signal of wheel drive motors according to above-mentioned calculated signals, and then control wheel drive motors make battery-driven car can regulate the car body attitude automatically, finally realize the self-balancing of car body.
It is to rely on to recognize both legs and realize that the human body of described car body supports, and there is no shaft-like handle.That is to say that the utility model is to utilize program to realize the self-equalizing of car body, thereby has simplified the structure of car body.
Structure of the present utility model only comprises car body, wheel and power drive system etc.Its wheel adopts the ordinary bicycle spoke wheel, and wheel is installed in the car body both sides, forms two-wheeled left and right sides distributed architecture, to reduce the turn radius of vehicle.For rotating shaft is connected, be that car body can form horizontal hunting around the rotating shaft of wheel between wheel and the car body.Car body has only vehicle body and should have enough loading strengths.Vehicle body is board-like, the placement of this suitable power supply, control system.Sensor is arranged on the car body, so that directly experience operation and the balance of car body.The core devices of control circuit adopts the PIC micro controller system, and driving circuit then adopts suitable form to make motor can just change, also can reverse.
The sensor that the utility model adopts comprises speed sensor and angular transducer, by they can measure car body operation conditions and equilibrium condition, comprise the corner of two-wheeled and the obliquity information of car body, feed back to control system, calculate cireular frequency and the angular acceleration of two-wheeled and car body, thereby calculate the needed motor torque of two-wheeled, realize the control to car body.
The mode that the utility model adopts is:
When car body does not tilt not move, angular transducer obtains car body dip angle signal (almost nil) and sends into the control control system, the control system speed sensor signal (almost nil) of signal and comprehensive left and right wheel accordingly calculates the required motor torque controlling quantity of two-wheeled, in this controlling quantity input driving circuit, after processing such as power gain, be sent in the drive motor, make car body keep the original place balance.When car body is advanced, the driver turns forward car body slightly, angular transducer obtains dip angle signal and sends into control system, control system signal and comprehensive left and right vehicle-wheel speed sensor signal is accordingly calculated the required motor torque controlling quantity of two-wheeled, in this controlling quantity input driving circuit, be sent in the drive motor after processing such as power gain, the control wheel rotates and remains the car body balance forward.The inclination angle is more big, accelerates more fast.When needs slowed down, brake or retreat, the driver receded car body a little, and control system equally also can calculate required counter torque, and then the control wheel turns round to send out troops to fight and remains the car body balance.The inclination angle is more big, oppositely accelerates more fast.When needing to turn, the left-leaning left-hand rotation of driver, Right deviation are turned right.
In sum, the utility model is compared with existing battery-driven car and is had the following advantages:
1. two wheels distribute about being, the turn radius of vehicle is zero, can be in little spatial dimension flexible motion;
2. calculate the output controlling quantity by program, control the both sides wheel respectively by control circuit, not only make car body can keep balance automatically, and do not need brake, reversing, the balanced system of physical structure, make mechanism simple;
