Self balancing board with main wheel and distal auxiliary wheels

摘要

There is provided a self balancing board comprising a wheel assembly, a platform, at least one sensor, a controller, a first auxiliary wheel assembly and a first brake element. The main wheel assembly includes a main wheel and a motor for driving the main wheel. The platform is fixed to the wheel assembly and has a foot deck. At least one sensor senses the orientation of the platform. The controller receives data from at least one sensor and controls the motor in response to the received data. The first auxiliary wheel assembly is secured to the platform at its original position relative to the wheel assembly and is elevated from contact with the ground to which the brakes are supported on the ground when the foot deck is parallel to the ground. The first brake element is manually movable relative to the first auxiliary wheel assembly to engage the first auxiliary wheel assembly to provide resistance to rotation of the first auxiliary wheel assembly.
