Electric balance vehicle

Abstract

The invention provides an electric balance vehicle, which comprises a vehicle body, four driving wheels and a control mechanism, wherein the vehicle body comprises a pedal and a support framework; the pedal is in a flat plate shape; the support framework is arranged at the lower part of the pedal; the four universal wheels are connected with the support framework and are in rectangular arrangement; the bottom surfaces of the four driving wheels are positioned in the same plane; the located plane of the bottom surfaces of the four universal wheels is parallel to the pedal; the control mechanism comprises four driving motors and a controller; the controller is connected with the driving motors and is used for controlling the driving force output by the driving motors; each driving motor drives one driving wheel to rotate; the controller controls the four driving motors to output the corresponding driving power to the four driving wheels according to the gravity center position information of a user on the pedal so as to drive the four driving wheels to rotate. The electric balance vehicle has the advantages that the vehicle body of a main body component is in a flat plate shape, so that the structure is compact; portability is realized; the storage is convenient; and the electric balance vehicle has four wheels, so that the balance performance of the electric balance vehicle is higher than that of other two-wheel walking-instead vehicles.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to an electric balance car. Background technique [0002] Two-wheeled scooters are built on a fundamental principle known as "dynamic stability," the ability of the vehicle itself to balance itself. The built-in precision solid-state gyroscope is used to judge the posture state of the car body, and the precise and high-speed central microprocessor calculates the appropriate command, and then drives the motor to achieve the balance effect. [0003] Suppose we take the vertical axis of the overall center of gravity of the driver standing on the car and the vehicle as the reference line. When this axis tilts forward, the built-in electric motor in the body will generate forward force, on the one hand, it will balance the torque of people and the car falling forward, and on the other hand, it will generate the acceleration that makes the vehicle move forward. On the contrary, when the g...

However, it is mainly composed of two relatively movable brackets, and its balance is not easy to control during use.

Moreover, it is not very convenient to carry due to its space occupation
