FREIGHT LOADING TRAY FOR GENERATING INDUCED ELECTROMOTIVE FORCE ON A GUIDE UNIT TO ACT REPULSIVE FORCE ON A ROD UNIT ACCORDING TO THE CHANGE OF MAGNETIC FLUX GENERATED IN A GUIDE HOLE WHILE OPENING A GATE

摘要

PURPOSE: A freight loading tray is provided to reduce the opening speed of a gate and to prevent the gate and a lower frame from breaking down. CONSTITUTION: A freight loading tray is composed of a gate(120) hinge-combined at a lower frame(110); a rod unit(130) with ferromagnetism fixed at the gate; and a guide unit(140) settled at the lower frame, made of conducting materials, and formed with a guide hole. The rod unit is inserted into the guide hole. An insulating seat for electrical insulation is disposed on the outer peripheral surface of the guide unit and a wire is wound around the seat to set inductance differently. Induced electromotive force generated at the guide unit forms magnetic field to repulse the rod unit along the guide hole. Accordingly, the gate is decelerated and the rod unit is inserted into the guide hole.
