Publication number: 20240001709Abstract: A wheel unit for overcoming an obstacle includes a hub, a plurality of unit blocks and a supporting body. The hub rotates by receiving a rotating force. The plurality of unit blocks is spaced apart from the hub and forms an outer shape of the wheel unit. The supporting body is configured to connect the hub with the unit blocks, or is filled between the hub and the unit blocks. The supporting body applies a tension to the unit blocks along a direction toward the hub, to close up the unit blocks with each other, when the wheel unit passes through a ground. The unit blocks adjacent to each other are relatively rotated or moved, when the wheel unit overcomes an obstacle.Type: ApplicationFiled: January 12, 2022Publication date: January 4, 2024Inventors: Sung Hyuk SONG, Chan Hun PARK, Byung In KIM, Jeong Ae BAK, Dong Il PARK, Jong Woo PARK, Hwi Su KIM, Hyun Uk SEO, Jae Young LEE, Yong Sin SEO, Hyun Mok JUNG

Patent number: 11192241Abstract: In an apparatus for adjustable counterbalance mechanism and a method for controlling the apparatus, the apparatus includes a reference surface, a link, an elastic member, a wire, an idle roller and a compensation torque. The link has a first end rotationally connected to the reference surface to form a rotational center, and a weight center of the link is spaced apart from the rotational center. The elastic member has a first end combined with the link. The wire has a first side combined with a second end of the elastic member, and a second side combined with the reference surface. The idle roller is combined with the link to support a portion between first and second ends of the wire. The compensation torque controller is equipped to the link, to control the position of the idle roller and an elastic force of the elastic member.Type: GrantFiled: March 3, 2017Date of Patent: December 7, 2021Assignee: KOREA INSTITUTE OF MACHINERY & MATERIALSInventors: Hwi-su Kim, Young-su Son, Chan-hun Park, Dong-il Park, Hyun-min Do, Tae-yong Choi, Doo-hyeong Kim, Jin-ho Kyung

Patent number: 10421198Abstract: A counterbalancing linkage mechanism includes a base link including a first joint; a second link forming a second joint to be rotatably connected to the base link; and a counter balancer having one portion disposed at the second joint and another portion movably disposed at the base link along a length direction of the second link. The counter balancer compensates a gravitational torque generated due to a weight of the second link when the second link rotates on the second joint. A third link is connected to the second link. The counter balancer comprises a counter balancer delivery portion connected to the second link and rotating by the rotation of the second link. A counter balancer driving portion is in contact with the counter balancer delivery portion, linearly moves by the rotation of the counter balancer delivery portion, and compensates the gravitational torque and a load capacity due to interaction with the counter balancer delivery portion.Type: GrantFiled: February 11, 2016Date of Patent: September 24, 2019Assignees: KOREA UNIVERSITY RESEARCH AND BUSINESS FOUNDATION, HYUNDAI MOTOR COMPANY, KIA MOTORS CORPORATIONInventors: Jae-Bok Song, Hyun Soo Lee, Hwi-su Kim, Seung Woo Song
