INELASTIC SUSPENSION FRAME STRUCTURE FOR AUTOMATICALLY GUIDING VEHICLE

WIPO Patent Application WO/2020/119388

A1

Disclosed is an inelastic suspension frame structure for automatically guiding a vehicle. The frame structure is connected to driving wheel assemblies (30L, 30R) and a frame portion (20) automatically guiding the lower portion of the vehicle, and comprises: vertical guiding components (40), supporting a pair of driving wheel assemblies (30L, 30R) in such a manner that the pair of driving wheel assemblies (30L, 30R) are able to move in a perpendicular direction relative to the frame portion (20); a rotary shaft (50), rotatably fixed on the frame portion (20); and a first cam component (60A) and a second cam component (60B), which are combined with the rotary shaft (50) in an eccentric manner and rotate with the rotary shaft (50), and peripheral surfaces of the first cam component (60A) and the second cam component (60B) are in contact with upper end face of each of the driving wheel assemblies (30L, 30R), and the eccentric direction of the first cam component (60A) from the center of the rotary shaft (50) and the eccentric direction of the second cam component (60B) from the center of the rotary shaft (50) are in opposite directions. The inelastic suspension frame structure enables a vehicle to keep horizontal on uneven ground and achieve a complete and stable grounding.
