Abstract

La présente invention concerne une planche à roulettes électrique à une roue et, plus spécifiquement, est caractérisée en ce qu'elle permet à la direction de cap et sa vitesse de cap d'être commandées par l'intermédiaire d'un dispositif de commande de façon à permettre à un utilisateur de se déplacer avec une posture stable et confortable puisque le déplacement du centre de gravité vers l'avant pour appliquer une force ou une inclinaison vers le sol afin de se déplacer, comme avec une planche à roulettes électrique classique, n'est pas nécessaire, permettant à l'utilisateur de faire fonctionner le dispositif de commande de façon à permettre un ajustement de vitesse large et précis, et résolvant les problèmes dans lesquels : la partie avant de la planche à roulettes entre en collision avec le sol ou la planche à roulettes se déplace soudainement vers l'arrière à grande vitesse dans une région de montée, qui sont des problèmes structurels et systématiques dans une planche à roulettes électrique classique ; la planche à roulettes accélère davantage ou sa partie arrière entre en collision avec le sol sur une pente descendante, provoquant des accidents inévitables ; et la planche à roulettes a un dysfonctionnement soudain et ne peut pas être commandée sur un sol non-uniforme, tel qu'un sol irrégulier en raison de problèmes structurels et systématiques, amenant l'utilisateur à tomber brutalement et, de ce fait, la présente invention permet une conduite sûre indépendamment de la pente ou courbe de la route.
