Control circuit and control method of balance bike

Abstract

The invention discloses a control circuit of a balance bike. The control circuit comprises a power source, a power driving circuit is coupled on the power source and used for controlling on-off of thepower source, a single chip microcomputer, a left motor and a right motor are coupled on the power driving circuit, the single chip microcomputer is used for processing signals, a left motor coder isconnected on the left motor, a right motor coder is connected on the right motor, and both the left motor coder and the right motor coder are coupled with the single chip microcomputer; the power driving circuit comprises an isolation chip, a motor driving chip and a switch power source chip, the isolation chip is used for isolating the single chip microcomputer from the motor driving chip, the motor driving chip is used for receiving PWM signals sent by the single chip microcomputer, sending the same to the left motor and the right motor and controlling rotating direction and rotating speedof the left motor and the right motor, and the switch power source chip is used for providing power source voltage stable at 5V for the single chip microcomputer.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, in particular to a control circuit of a balance car and a control method thereof. Background technique [0002] Two-wheel self-balancing balance car is a commonly used fitness equipment. It is driven independently by two coaxial wheels. The center of the body is located above the wheel axle. It maintains balance through exercise and can walk upright without external force. When the exerciser stands on the balance car, he can effectively exercise his balance ability, because once the standing posture is not correct, the horizontal balance of the balance car will be easily destroyed, the emergency system of the balance car will be activated, and the balance car will be stopped. The automatic balancing operation principle of the self-balancing car is mainly based on a basic principle called "Dynamic Stabilization", which is the automatic balancing ability of the vehicle itself.

Problems solved by technology

[0003] However, in the prior art, due to the unevenness of some road surfaces, small bumps will occur on the self-balancing car, and if such small bumps can also cause the self-balancing car to brake, it will appear that the self-balancing car is too "sensitive". In the technology, shock absorbers are generally installed at the wheel positions of the self-balancing car to reduce such bumps. However, the shock-absorbing effect of the shock absorber is unstable, and the self-balancing car is small in size. Installing the shock absorber will cause the balance The weight balance of the car is broken and needs to be adjusted during manufacture, which increases the manufacturing cost of the balance car and reduces production efficiency
