Description

Electric balance car pedal, upper frame and electric balance car

[0001] The present invention relates to an electric balance vehicle pedal, an upper frame, and an electric balance vehicle.

Background technique

[0002] The electric balance car, its operation principle is mainly based on a basic principle called "dynamic stability", using the gyroscope and acceleration sensor inside the car body to detect the change of the car body posture, and using the servo The control system, the drive motor is adjusted accordingly to maintain the balance of the system. It is a new kind of green environmental protection product used by modern people as a means of transportation and recreation. Generally, the two-wheel electric balance car mainly includes two hub motors with axles, pedals between two hub motors, etc. .

[0003] There are many types of electric balance twisting vehicles involved, but most of them have the following problems. A resetting member, such as a spring, is installed between the pedal and the balance switch of the balance car. After the force is applied to the foot, even if the force of the foot is removed, the spring may always exert an elastic force on the touch switch, and the twisting car is not artificial. Control, easy to cause accidents; and the installation of the resetting parts is cumbersome, it is not easy to maintain and replace; the pedal and balance car are installed by the housing to press the pedal to the balance car to prevent it from being detached, and some usually glue the pedal to the balance. In the car, but such a type of pedal installation, the pedals are easy to fall off, it is not easy to install and maintain again after falling off. Summary of invention
