Embodiment approach

[0010] The vehicle frame of the present invention is a cuboid frame, and is hinged at one point on the center of gravity line of the seat behind the passenger at the upper center position. Mount the handle at the upper front end of the vehicle frame (that is, the armrest). The left hand is the climbing handle, which can be tilted to two positions, namely "up" and "down". The right hand is the walking direction handle, which can be tilted in four directions: "front", "back", "left" and "right". Around the handle is a travel switch. When the direction is selected, press down on the side of the little finger of the palm, and the car will move. If you press deeply, it will be fast, otherwise it will be slow. The rear parts of left and right elbows are equipped with brake backing plates.
