Electric four-wheel balance vehicle

Abstract

The present invention discloses an electric four-wheel balance vehicle includes a housing, a pedal device, a balancing device, a driving device, and a power supply device. The balancing device is provided in the housing. The pedal device includes a pedal, a fixed frame, and an elastic pad. The housing is provided with two pedal holes. The pedal is movably embedded in the pedal hole, and is limited in the housing by the fixing frame located on a top of the pedal. The elastic pad is provided between the housing and the pedal. The balancing device is provided in the housing, and is coupled with the pedal in a transmittable manner. The driving device includes a control board, two front motor-wheels, and two rear universal wheels. The balancing device is connected to the control hoard in a communicating manner.

What is claimed is:
