▎ 摘　　要

NOVELTY - The car has a supporting plate (3) whose top is equipped with a first roller (4). The surface of the first roller is provided with several groups of bumps. The number of installations of first rollers is 4 groups, and are installed vertically in pairs. The surface of first roller is wrapped with a rubber sleeve (5). The surface of the first roller away from rubber sleeve is coated with a graphene coating (6). The graphene coating is in shape of an open ring. A conductive metal sheet is fixedly installed on the bottom of the supporting plate. One end of the conductive metal sheet is connected with the opening of the graphene coating. An electric wire is connected between any two groups of parallel graphene coatings. The four vertical surfaces of a AGV trolley main portion (1) are equipped with blue warning lights (9). The blue warning light is connected with the control module. The end of conductive metal sheet away from graphene coating is connected to the blue warning light. USE - Automatic guided vehicle (AGV) car with safety detection structure for intelligent sorting of goods, displacement, storage of three-dimensional (3D) warehouse, and warehousing logistics. ADVANTAGE - The AGV trolley identifies dangerous light source for avoiding by the color sensor, improves the safety of transportation. The rubber sleeve is covered on the surface of the first roller, by increasing friction, and the shelf drives the roller to rotate the acting force, ensures the shelf offset sliding, and the roller accurately rotates, graphene coating is connected with the conductive metal sheet in time, forms a closed circuit for supplying power to the blue warning light, so that the control module timely receives the shelf offsets information and is conveyed to the external control system, and is convenient for working staff processing the offset condition. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a using method of AGV trolley with safety detection structure. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of AGV car with a safety detection structure. 1Agv trolley main portion 3Supporting plate 4First roller 5Rubber sleeve 6Graphene coating 9Blue warning light 10Groove portion 11Roller shaft 15Second fixing frame 16Color sensor 28Vacuum suction disc 31Rotating shaft 32Cleaning plate
