Abstract: A bumper device for an Automated Guided Vehicle (AGV) includes a bumper supporting member combined to a vehicle body of the AGV, and a bumper supported on the bumper supporting member. The bumper device also includes a movement supporting device installed at the bumper supporting member and to movably support the bumper, and a movement sensor to sense a movement of the bumper. Thus, the bumper device promptly senses and effectively absorbs an impact from multiple directions.

Abstract: Disclosed is a bumper device for an AGV comprising a bumper supporting member combined to a vehicle body of the AGV, and a bumper supported on the bumper supporting member, further comprising a movement supporting means installed at the bumper supporting member and movably supporting the bumper; and a movement sensor sensing a movement of the bumper. With this configuration, the present invention provides a bumper device for an AGV, which can promptly sense and effectively absorb an impact given from every region and every direction.
