Embodiment Construction

[0031] First, an embodiment of the rocker truck mechanism of the present invention will be described.

[0032] first embodiment

[0033] The rocker truck mechanism of this embodiment has a center frame and a pair of running parts symmetrically attached to the center frame. The pair of running parts are respectively equipped with a rocker frame supported and fixed to the central frame by a shaft rod, a bogie frame pivoted to one end (first end) of the rocker frame, and a bogie frame pivoted to the rocker frame respectively. The other end (second end) and the first wheel, the second wheel and the third wheel at the two ends of the bogie frame.

[0034] Each swing arm frame of the pair of running parts has a frame portion extending in the horizontal direction. That is, each rocker arm frame has two frame parts which are respectively located between the first end part and the second end part, and are bent separately in the horizontal direction from the position pivoted to the ce...

Abstract

This rocker bogie mechanism is thin and has a structure in which a center frame is provided and a pair of independently traveling rocker bogies are disposed on both sides of the center frame. Each ofthe rocker bogies has a structure in which a rocker frame that constitutes the rocker bogie is pivotably supported by the center frame, and extends basically horizontally. Using this rocker bogie mechanism as a truck and mounting a main body on the center frame makes it possible to constitute a travel device that has both strength and handling ability with respect to level differences.

Description

technical field [0001] The present invention relates to a rocker bogie mechanism, in particular to a rocker bogie mechanism suitable for use on a walking device for people. Background technique [0002] The four-wheeled electric scooter that is widely used at present often encounters an accident of being unable to move or overturning because one of the four wheels is suspended in the air and cannot touch the ground when encountering a step difference. In addition, there are problems such as difficulty in changing routes on narrow roads because it is impossible to turn around on the spot. [0003] On the other hand, in the field of self-propelled vehicles such as robots, a traveling device equipped with a rocker bogie mechanism (for example, Patent Document 1) is often used to travel on irregular ground with bumps. The aforementioned rocker bogie mechanism has two connecting rods (rocking arm and bogie) that are flexibly connected to each other, and the lower ends of each co...
