Description

Intelligence lithium electricity balance car with prevent falling mechanism

Technical Field

The utility model relates to an intelligence lithium electricity balance car field specifically is an intelligence lithium electricity balance car with prevent falling mechanism.

Background

The electric balance car, also called a body sensing car, a thinking car, a position pickup car and the like, is a novel green product used by modern people as a travel tool and leisure and entertainment. The market mainly comprises a single wheel and two wheels. The operating principle is mainly based on a basic principle called dynamic stability. The change of the posture of the vehicle body is detected by utilizing a gyroscope and an acceleration sensor inside the vehicle body, after the posture of the vehicle body is detected, feedback information is returned to a control center, and the sent deviation rectifying control command is slower than the action of falling of a human body to the process of executing the deviation rectifying action. Two-wheeled electrodynamic balance car adopts the two-wheeled mode of fixing side by side, and two-wheeled electrodynamic balance car adopts two wheels to support, wholly is a regular straight body, does not have triangular stability. The balance car is powered by a storage battery and driven by a brushless motor, and is controlled by a single chip microcomputer, an attitude sensor acquires angular speed and an angular signal, the balance of the car body is coordinated and controlled together, and actions such as starting, accelerating, decelerating, stopping and the like of the car can be realized only by changing the gravity center of a human body. Because a driver usually runs in a standing mode, inertia is often accompanied in the processes of starting, accelerating, decelerating and stopping, when the speed is too high or the road surface is not flat, the inertia can exceed the self-balance range of the human body instantly, so that the balance car is out of control in a tilting way, particularly for children with poor balance control and weak strain capacity, the children are easy to fall down and hurt to cause safety accidents, and the children running for a long time in a standing mode can also easily cause fatigue to cause safety accidents due to control errors.
