How children's balance car works The principle of electric unicycle does not fall: On the one hand, because people can adjust the center of gravity and adjust the direction of the car's direction, the direction of change in the direction of the car can be balanced due to inertia. It is also important that the wheels rotating at high speeds have large angular momentum and that the angular momentum can resist the external torque, just as the gyro does not fall. In university physics, this phenomenon is called precession, and the autobiographical body can rotate the direction of the external moment by 90 degrees. Here is the wheel turning the rollover moment into the torque that turns the bike. Use motors to enhance balance: On this basis, self-balancing electric unicycles are improved. Driven by motors, the gyroscopes and drive circuits are used to maintain control. Tilt your body forward to start. The speed is controlled by the inclination of the body. If you want to speed up, you will lean forward and if you slow down, you will lean back. Put aside people's active control, children's balance car to ensure normal work must be separated from the acceleration sensor and angular velocity sensor (gyroscope) Accelerometer: The accelerometer can measure the acceleration generated by the gravitational force of the earth or the motion of the object. You only need to measure the acceleration in one of the directions to calculate the vehicle inclination. For example, the X-axis acceleration signal is used. When the vehicle is upright, the fixed accelerometer is in the horizontal direction of the X-axis, and the output signal is a zero-bias voltage signal. When the car is tilted, the gravitational acceleration g forms an acceleration component in the X-axis direction, causing a change in the output signal of the shaft. However, during the actual operation of the vehicle, the acceleration generated by the movement of the balancing vehicle itself generates a large interference signal superimposed on the above-mentioned measurement signal, so that the output signal cannot accurately reflect the true inclination angle. Therefore, the attitude information required for the upright control cannot be completely obtained by the acceleration sensor. Angular speed sensor: A gyroscope can be used to measure the rotational speed of an object. A gyroscope is mounted on the balance car to measure the angular speed of the car's tilt, and the angular velocity signal can be integrated to obtain the car's tilt angle. Balance car's core components: When it comes to balance, we have to talk about gyroscopes. The principle of gyroscopes is that the direction of the axis of rotation of a rotating object does not change when it is not affected by external forces. According to this principle, people use it to keep the direction and make something called a gyroscope. We also use this principle to ride our bicycles. The faster the wheels turn, the less likely they are to fall, because the axle has a level of strength. The gyroscope should give it a force while working, making it spin up quickly, generally reaching hundreds of thousands of revolutions per minute, and can work for a long time. Then use a variety of methods to read the direction indicated by the axis and automatically pass the data signal to the control system.
