A two-wheel balance vehicle having a foldable structure. The two-wheel balance vehicle having a foldable structure comprises a main body supporting frame and two wheels (7a, 7b) mounted at outer sides of the supporting frame. The supporting frame comprises five hingedly-connected elements hingedly connected to each other. Two ends of an upper hingedly-connected element (2) are hingedly connected to upper ends of two lateral hingedly-connected elements (3, 5) respectively. One end of one of two lower hingedly-connected elements (4a, 4b) and one end of the other of the two lower hingedly-connected elements (4a, 4b) are hingedly connected to each other, and the other ends of the two lower hingedly-connected elements (4a, 4b) are hingedly connected to lower ends of the two lateral hingedly-connected elements (3, 5) respectively. The main body supporting frame also comprises a telescopic portion (8). The upper end of the telescopic portion (8) is fixed to the middle of the upper hingedly-connected element (2), and the lower end of the telescopic portion (8) is fixed to the mutually hingedly-connected ends of the two lower hingedly-connected elements (4a, 4b). When the telescopic portion (8) is extended, the mutually hingedly-connected ends of the two lower hingedly-connected elements (4a, 4b) are driven to downwards move, thereby allowing the main body supporting frame to be in a folded state. The balance vehicle can be rapidly folded and unfolded, the size of the folded balance vehicle is small, and the shape is in order, thereby allowing the balance vehicle to be conveniently carried and accommodated, and the safety and the passing ability of the unfolded balance vehicle in use can also be improved. |
