The invention discloses an elevator anti-falling flexible buffer system, and relates to the technical field of elevator falling prevention. According to the technical scheme, the elevator anti-falling flexible buffer system is characterized by comprising an elevator shaft internally provided with a car rail; and an elevator car provided with rail pulleys. A conduction coil body surrounding the bottom end of the car rail is arranged in the elevator shaft, and a strong permanent magnet set is arranged on the elevator car. When the elevator car moves downwards in the conduction coil body, induced current generated in the conduction coil body can form ampere force for preventing the strong permanent magnet set from moving. Three flexible braking assemblies are adopted for achieving the flexible braking anti-falling effect, and the three flexible braking assemblies are combined so that the reliability of the whole system can be improved.
