Abstract
The utility model relates to a dumpable portable motor-tricycle. A T-shaped shaft, a resetting mechanism and a positioning mechanism are arranged on the dumpable portable motor-tricycle. The motor-tricycle is structurally characterized in that the motor-tricycle body of the front part and the motor-tricycle body of the rear part are connected with each other to form an integrative structure by the T-shaped shaft which can rotate. When the motor-tricycle turns, the motor-tricycle body of the front part can automatically incline, and the motor-tricycle body of the rear part does not incline. Thereby, the defect that the motor-tricycle turns over because the rear wheel of the outer side easily spring up and lifts off when the motor-tricycle turns is overcome. Simultaneously, the resetting mechanism on the rear wheel can repress the tricycle body of the front part to overly incline, and the positioning mechanism can cause the tricycle bodies of the front part and the rear part to form into a whole. The utility model has the characteristics of safe riding, comfort, low cost, novel structure, etc. Thus, the utility model is an ideal vehicle for a person riding or two persons riding.
