Abstract

The invention discloses a radially repeated folding wheel mechanism. The current complex terrain mobile detection vehicles need to be strengthened to adapt to unstructured terrain. The crank hub of the present invention is fixed to one end of the movable spoke connecting shaft, and the other end of the movable spoke connecting shaft is threadedly connected to the axially moving spoke; the crank hub is provided with a crank push rod, and the top end of the crank push rod is hinged with a rolling sleeve; The top of the moving spoke rod is slidably connected with the axial chute of the wheel rim, and the middle part is fixed with the locking block; the locking block is provided with a wheel rim push rod chute, and two ends of the wheel rim push rod chute are provided with two protrusions; The radial chute of the ring is slidingly connected with the rim push rod; the bottom of the rim push rod is fixed with a sleeve connecting rod, and the top is respectively fixed with the rim slanting block; the side wall of the rim push rod is provided with a shrinkage locking groove, The other side wall is provided with an unfolding locking slot. The invention can change the diameter of the wheel and the contact mode between the wheel and the ground, and enhance the adaptability of the mobile vehicle on complex terrain to unstructured terrain.

Description

technical field [0001] The invention belongs to the technical field of robots, and relates to a folding and unfolding wheel mechanism, in particular to a radially and repeatedly folding and unfolding wheel mechanism. Background technique [0002] Wheeled complex terrain mobile detection vehicles are widely used in space planet exploration, military operations, search and rescue activities and other fields. The wheels of the wheeled complex terrain mobile detection vehicle, as its parts directly in contact with the ground, not only carry the overall weight of the vehicle, generate traction, and feed back the necessary terrain information, but also play a role in the movement ability, steering flexibility, adaptability, etc. of the vehicle. Capabilities such as terrain have a significant impact. [0003] Although the current complex terrain mobile detection vehicles have a strong ability to overcome obstacles, their ability to adapt to special unstructured terrain still needs...
