Many people wonder how the balance car is balanced. The information from Baidu is like this: its operating principle is mainly based on a basic principle called “dynamic stability”, which is the automatic balancing ability of the vehicle itself. . The built-in precision solid-state gyroscope is used to judge the posture state of the vehicle body, and the motor is driven to achieve a balanced effect after calculating an appropriate command through a precise and high-speed central microprocessor.

Very tall and deep, but most people said that they could not understand. Today, Honey and Xiaobian will simply talk about how the balance car works.

Electric unicycle balance car

Let's talk about the electric unicycle balance car. The balance of the unicycle balance car mainly depends on the gyroscope and the drive circuit. With the gyroscope (including the acceleration sensor and the angular velocity sensor), the motor starts, and the body tilts forward to start the balance car. The speed is controlled by the degree of inclination of the body, the acceleration is tilted forward, and the slowdown is backward.

The gyroscope is the core component of the balance car. The principle is such that the direction indicated by the rotating axis of a rotating object does not change when it is not affected by external force. Cycling is also the use of this principle, the faster the wheel turns, the less likely it is to fall, because the axle has a level of strength. This is the principle that the unicycle balance car will not fall.

The wheelbarrow also needs a controller to communicate the interaction between the gyroscope and the motor drive. When the driver leans on the body, the gyroscope receives the information. At this time, the controller is required to tell the motor driver how to do it, like the corresponding Direction rotation.

The controller needs to constantly adjust the direction and speed of the motor so that we can keep it smooth during the ride.

Two-wheel balance car

The two-wheel electric balance car is mainly composed of two parts, one part is the main body of the two-wheel electric balance car; the other part is the direction control rod of the two-wheel electric balance car.

Compared with the unicycle, the two-wheeled balancer has one more wheel and direction control lever, which is relatively easier to operate. The direction control lever is used to control the direction of the vehicle body during operation.

And its built-in module is also similar to the unicycle, control module, gyro module and motor. The two-wheel self-balancing control system is a kind of two-wheel parallel arrangement. It is driven by the motor, two wheels replace your feet, and the joystick controls the direction.
By inducing the direction of the body's center of gravity to adjust the direction, the body leans forward, backwards backwards, and stands still, this is the so-called "dynamic balance" principle.

In fact, the whole feeling is a bit like the treadmill game we played. The more you lean forward, the faster the speed will be, just to maintain balance.

Of course, there are not only the modules mentioned above, but also a complete set of intelligent running systems to make you safer while driving. In principle, as long as the power is turned on and the power is sufficient to operate, the balance car is safe to drive and the possibility of falling is low.
