Description

Electric balance car and pedal assembly thereof

[Technical Field]

The present invention relates to the field of balancing vehicles and, more particularly, to an electric balancing vehicle and its pedal assembly.

【Background technique】

Electric balance vehicles, also known as somatosensory cars, thinking cars, camera cars, etc., currently have two types of wheels and two wheels on the market. The principle of operation is mainly based on a kind of “Dynamic Stabilization (DS). The basic principle is to use the gyroscope and acceleration sensor inside the car body to detect the change of the car body posture, and use the servo control system to accurately drive the motor to adjust accordingly to maintain the balance of the system.

Generally, the two-wheel electric balance vehicle mainly includes: a load-bearing base body for supporting the weight of the user, a pedal member, a rubber body having a certain elastic deformation function disposed on the load-bearing base body, and an optocoupler switch disposed on the load-bearing base body. After the user applies pressure to the pedal member, the cylinder in the middle of the rubber body will move downward due to the pressure, so that the optocoupler switch senses the light change, generates an induction signal, and controls the electric balance vehicle to stop, and when the user cancels the above When the pressure is applied, the rubber body will return to the initial position due to its elastic restoring force, so that the photocoupler detects the light change and generates another sensing signal to control the electric balance car to continue to travel. However, since the rubber body itself has poor resistance to low temperature, in a sub-zero temperature environment, it is easy to become brittle and broken, and cannot be deformed normally, resulting in the electric balance car not working properly.

In the present invention, the pedal assembly includes a bottom plate, a trigger plate, and an optocoupler switch. One end of the trigger plate is connected to the bottom plate through a rotating shaft, and the other end of the trigger plate is coupled with an optocoupler switch, and the rotating shaft is provided with a metal elastic component. The control end of the metal elastic component is connected to the trigger board, and one end of the trigger board and the optocoupler switch is upturned. When an external force is applied, the external force exerts a downward force on the end of the trigger plate, and the trigger plate applies a downward force to the control end of the metal elastic member, and the metal elastic member is compressed to generate an upward restoring force, which triggers One end of the board and the optocoupler switch moves downward, and one end of the trigger board and the optocoupler switch controls the optocoupler switch. When the external force disappears, the restoring force of the metal elastic component causes the end of the trigger plate and the optocoupler switch to move upward. One end of the trigger plate that mates with the optocoupler switch leaves the optocoupler switch. In this way, the pedal assembly controls the optocoupler switch through the trigger plate and the metal elastic component, and has strong adaptability to temperature, and does not cause a problem of slow deformation or deformation due to low temperature, thereby ensuring that the entire electric balance car is at a low temperature.
