Moreover, the outward extending bending edge of the first middle car wall plate and the inward bending edges at both ends of the door lintel assembly can be fixed, and the outward extending bending edges on both sides of the second middle car wall plate and the inward bending edge at one end of the rear car wall plate are fixed, and the inward bending edge at the other end of the rear car wall plate and the outward extending bending edge of the first middle car wall plate on the other side of the first side car wall plate are fixed, so that a labyrinth structure is formed at the splicing joints of the elevator carriage, and a high-temperature resistant and flame-retardant sealant is filled at the splicing joints to improve the sealing performance of the elevator carriage, realizing the prevention of smoke and dust from entering through the splicing joints of the elevator carriage and solving the problem of poor airtightness at the splicing joints of the elevator carriage.
