The invention belongs to the technical field of elevator safety design and provides a bottom double-component buffering device for elevator falling. The bottom double-component buffering device comprises a falling protection controller, a power source, a gravity acceleration sensor, a wireless signal alarm, a stress sensor, a wire harness, high-pressure air cushions and high-pressure springs. The falling protection controller, the power source, the gravity acceleration sensor and the wireless signal alarm are sequentially arranged on the upper surface of the top of a lift car. The stress sensor is arranged on the lower surface of the top of the lift car. The high-pressure air cushions and the high-pressure springs are all arranged at the bottom of the lift car. According to the bottom double-component buffering device, when the falling protection controller monitors that the lift car falls through the gravity acceleration sensor, the wireless signal alarm is controlled to be opened, and ambulancemen are informed and can be in time for rescue. The bottom double-component buffering device is reasonable in design, simple in structure and suitable for optimal design of a vertical elevator falling loss system.
