Title:
SAFE TWO-WHEELED SELF-BALANCING VEHICLE
Document Type and Number:
WIPO Patent Application WO/2017/107838
Kind Code:
A1
Abstract:
A two-wheeled self-balancing vehicle comprises: two powered wheels (2); a motion sensor; a control circuit; a chassis structure (1); a direction control input device; and a power source. The powered wheels (2) are installed at two sides of the chassis structure (1). The motion sensor is connected to the control circuit and fixed to the chassis structure (1) opposite thereto. The direction control input device is connected to the control circuit. The control circuit drives the powered wheels (2). A protection wheel support (3) is disposed at a front side or both the front side and a rear side of the chassis structure (1). A floating protection wheel (4) is installed at a front end of the protection wheel support (3). The manner in which the protection wheel support (3) is connected with the chassis structure (1) or a structure of the protection wheel support (3) itself enables the floating protection wheel (4) to move freely in a vertical direction with respect to the chassis structure (1). A locking device (5) is connected to the chassis structure (1) and the protection wheel support (3). When the locking device (5) is in a locked state, the floating protection wheel (4) is in a location where it is fixed to the chassis structure (1). When the locking device (5) is released, the floating protection wheel (4) moves freely in the up-down direction. When being driven normally, the two-wheeled self-balancing vehicle can move in the up-down direction and be in contact with or close to the ground without experiencing a force. In the event of an emergency brake or a danger resulting from loss of control of the vehicle, the protection wheel (support) can be driven by a force from a rider or electricity to be fixed with respect to the vehicle frame, thereby providing protection quickly.
