Embodiment Construction

[0054] First, an embodiment of the rocker bogie mechanism of the present invention will be described.

[0055] first embodiment

[0056] The rocker bogie mechanism of the present embodiment includes a center frame and a pair of running parts symmetrically attached to the center frame. Each of the pair of running parts includes a rocker frame supported and fixed to the center frame by a shaft, a bogie frame pivoted to one end (first end) of the rocker frame, and pivoted to the rocker frame, respectively. The other end (the second end) of the bogie frame and the first wheel, the second wheel and the third wheel at both ends of the bogie frame.

[0057] Each of the rocker frames of the pair of running parts has a frame part extending in the horizontal direction. That is, each rocker frame has two frame portions, the two frame portions are respectively located between the first end portion and the second end portion, and are separately bent in the horizontal direction from the p...

Abstract

The rocker truck mechanism of the present invention is a thin rocker truck mechanism, which includes a central frame, and a pair of rocker trucks that are arranged on both sides of the central frame and can walk independently, and each rocker truck has a pivot The rocker frame is provided on the central frame and extends substantially along the horizontal direction. The rocker bogie mechanism is used as a trolley, and the main body is mounted on the central frame as a running device, which has both strength and a breakthrough for steps.

Description

technical field [0001] The present invention relates to a rocker arm bogie mechanism, in particular to a rocker arm bogie mechanism suitable for use on a manned walking device. Background technique [0002] At present, the widely used four-wheeled electric scooter is often unable to move or overturn because one of the four wheels cannot touch the ground when the stage is poor. In addition, there is still a problem that it is difficult to change a route on a narrow road because it cannot be turned on the spot. [0003] On the other hand, in the field of self-propelled vehicles such as robots, a traveling device having a rocker bogie mechanism (eg, Patent Document 1) is often used for traveling on uneven ground with irregularities. The aforementioned rocker arm bogie mechanism has two connecting rods (rocker arm and bogie) that are flexibly connected to each other, and a wheel unit is connected to the lower end of each connecting rod. Patent Document 1 describes an omnidirec...
