Abstract

A two-wheel dynamic balance vehicle comprises two wheels, a vehicle body, a middle cabin, a steering mechanism, and a control rod. The vehicle body is disposed on the two wheels. A pedal is disposed on the vehicle body. The middle cabin is disposed right above the pedal. The middle cabin comprises a housing. A display device is disposed on the housing, so as to make human-machine interaction information visible to an operator standing on the pedal. The steering mechanism comprises a steering shaft and a sensor. The control rod is connected to the steering shaft at the rear end of the vehicle body and extends from the rear end of the vehicle body to a position suitable for leg control of the operator. The control rod is rotated under the control of the operator, so as to drive the steering shaft to rotate to control steering of the vehicle body.
