The invention belongs to the technical field of elevator safety design and discloses a weightlessness triggering power-on execution mechanism. The weightlessness triggering power-on execution mechanism comprises a falling protection controller, a power source, an acceleration sensor, wire harnesses and forward electromagnetic field transmission mechanisms. The falling protection controller, the power source, the acceleration sensor and a wireless signal alarm are all arranged on the upper surface of the top of an elevator cab in sequence. The first forward electromagnetic field transmission mechanism and the second forward electromagnetic field transmission mechanism are arranged on the lower bottom face of the elevator cab. According to the weightlessness triggering power-on execution mechanism, when monitoring that the elevator cab falls down through the acceleration sensor, the falling protection controller controls the electromagnetic field transmission mechanisms to be turned on, so that an air cushion is formed between the first forward electromagnetic field transmission mechanism and the second forward electromagnetic field transmission mechanism, and falling buffer force is provided for trapped persons. The weightlessness triggering power-on execution mechanism is reasonable in design, simple in structure, and applicable to optimal design of a vertical elevator falling damage reduction system.
