Description

Electric balance car and its pedal assembly

technical field

The present application relates to the electromechanical field, in particular to an electric balance car and a pedal assembly thereof.

Background technique

Electric balance cars, also known as somatosensory cars, thinking cars, camera cars, etc., currently on the market mainly have two types of single-wheel and double-wheel. "Basic principle, use the gyroscope and acceleration sensor inside the car body to detect the change of the car body attitude, and use the servo control system to accurately drive the motor to make corresponding adjustments to maintain the balance of the system.

Usually, a two-wheeled electric balance car mainly includes: a load-bearing base for bearing the user's weight, pedals, a rubber body with a certain elastic deformation function arranged on the load-bearing base, and an optocoupler switch arranged on the load-bearing base. After the user exerts pressure on the pedal, the cylinder in the middle of the rubber body will move downward due to the pressure, so that the optocoupler switch will sense the light change and generate a sensing signal to control the electric balance car to stop. When the user cancels the above When the pressure is applied, the rubber body will return to the initial position due to its own elastic recovery force, so that the optocoupler switch senses the light change and generates another sensing signal to control the electric balance car to continue to move. However, due to the poor low-temperature resistance of the rubber body itself, it is easy to become brittle and broken in a sub-zero temperature environment, and cannot be deformed normally, resulting in the failure of the electric balance car to work normally.

Specifically, as shown in FIG. 5 , from the load-bearing base 211 to the suspension frame 212, the cross-section of the suspension frame 212 along the radial direction of the wheel shaft 11 is W-shaped.
