Elevator energy-absorbing buffer structure, integrated elevator car frame and preparation method thereof

The invention relates to an elevator energy-absorbing and buffering structure, an integrated elevator car cage frame and a preparation method thereof, and belongs to the technical field of elevator manufacturing, and the elevator energy-absorbing and buffering structure is characterized by comprising a plurality of curved-surface elastic pieces which are evenly distributed and fixedly arranged on the periphery of the bottom face of an elevator car, and the curved-surface elastic pieces are arranged on the periphery of the bottom face of the elevator car. The cross section of each curved-surface elastic piece is in an S shape from the bottom edge of the elevator car to the longitudinal axis of the edge, away from the bottom edge of the elevator car, of the curved-surface elastic piece, and the multiple curved-surface elastic pieces extend downwards from the bottom edge of the elevator car to the central axis of the lift car and are gathered together. Compared with a traditional elevator buffer, the elevator en
