Abstract: The present invention discloses a single-wheel electric balancing scooter, comprising a wheel, a driving motor located within the wheel, a battery pack serving as a power supply of the driving motor, a self-balancing control system, and a balance signal sensor. A saddle is provided above the wheel; the saddle is mounted on a rack which is connected and fixed to a fixed shaft of the wheel; a handle is provided on a front side of the wheel, with a lower end of the handle being connected to the rack; and a front end of the rack is connected with an auxiliary wheel rack and an auxiliary wheel is provided at a lower end of the auxiliary wheel rack. The present invention has the following advantages that it is easier for driving and better to control the balance of the scooter body; the scooter body may be dragged on the ground; and the scooter body may be kept upright when not in use.

Abstract: A sheet-type flange for transmitting power is formed by a substrate and a multiple of flange sheets. The substrate has a central axle hole with a square key slot and a multiple of fixed holes distributed around the axle hole. The multiple of flange sheets are annular and have connection slots arranged on a periphery of the flange sheets, as well as the multiple of flange sheets are arranged on both sides of the substrate respectively. The substrate and the multiple of flange sheets are fixed together by rivets.

Abstract: A punching sheet-type flange formed by overlapping and fixing punching sheet-structure assemblies, comprising a substrate (2) and multiple flange sheets (1) fixed with the substrate (2). The substrate (2) and the flange sheets (1) are of a punching sheet structure. The flange sheets (1) are annular, and connection slots (4) are arranged on the periphery of the flange sheets (1). The flange sheets (1) are arranged on both sides of the substrate. The substrate (2) combines with the flange sheets (1) to form the flange. The substrate (2) and the flange sheets (1) are formed by punching processing. The number of the flange sheets (1) is adjustable. The flange sheets (1) having the complex structure can be processed, thereby accommodating connecting parts of different structures. Connection slots (4) enable convenient assembling and replacement. The flange solves the difficulty in die casting of flanges having complex structures, and solves the problem of flange thickness being not adjustable.
