electric balance car, somatosensory car, two-wheeled self-balancing electric vehicle (segway), etc.

the birth of electric balance car was first caused by an automatic balance power wheelchair developed by scientists. carmen, an american inventor, observed the posture characteristics of human walking and realized that the reason why human beings can walk smoothlywalking upright, because the sensitive balance organ in the body can accurately judge the change of body weight and heart, through the immediate response of the cerebellum, and then use the muscles of the legs to immediately contribute to balance the dumping situation. therefore, when the human body is leaning forward, this involuntary reaction will urge human beings to stretch out one of the feet and step forward to balance the body, so through this leaning forward and stepping forwardaction loop, which constitutes the action of "walking.

the operation principle of electric balance car is mainly based on a basic principle called dynamic stability (dynamicstabilization). the built-in precision solid-state gyroscope is used to judge the posture state of the car body, through precise and high-speedcentral microprocessorafter calculating the appropriate instructions, drive the motor to achieve the balance effect.

suppose we take the driver standing on the car and the longitudinal axis of the overall center of gravity of the vehiclereference line. when this axis is tilted forward, the built-in bodyelectric motorit will generate forward force. on the one hand, it will balance the torque of people and cars dumping forward, and on the other hand, it will produce acceleration that makes vehicles move forward. on the contrary, when the gyroscope finds that the driver's center of gravity is leaning back, it will also produce backward force to achieve the balance effect. therefore, as long as the driver changes the angle of his body forward or backward, the electric balance car will move forward or backward according to the direction of inclination, and the speed is proportional to the degree of inclination of the driver's body.

the steering of the electric balance car can be achieved in two different ways, one of which is that the driver tilts his body's center of gravity to the left and right in the state that the vehicle continues to move forward or backward, use the component generated by its own weight perpendicular to the longitudinal axis of the vehicle body as the centripetal force during turning to achieve the purpose of steering. in addition, the driver can also reverse the handle part of the electric balance car to make the left and right wheels of the car produce a speed difference. for example, when the handle turns left, the speed of the right wheel will be higherleft wheelfast, achieve the effect of turning left. when necessary, the electric balance car can even make a round of forward and backward actions to achieve the effect of turning in place and greatly improve the mobility of this kind of vehicle.

due to this high mobility, plusglass fiberthe wheels made of materials and the pedal area are actually not much larger than human feet. theoretically, the electric balance car can reach most of the places that human beings can go, it even includes sidewalks on the roadside or stairs where the drop is not too large.

in principle, as long as the electric balance car turns on the power correctly and can maintain enough operating power, the people on the car don't have to worry about the possibility of dumping and falling, which is balanced by the driver himself.scooterand other means of transportation are very different.
