Abstract

The invention relates to a sliding plug door which comprises a supporting structure, a locking and unlocking mechanism and a transmission mechanism. A supporting structure composed of force bearing pillars and supporting blocks is used for establishing an installation platform of a whole door mechanism system. The locking and unlocking mechanism and the transmission mechanism are arranged on one side of the supporting structure and can complete locking, unlocking and sliding plug motion of a door leaf through a plug door screw rod and a sliding door screw rod correspondingly under the drive ofrespective drive motors. A sliding plug motion curve is obtained by synthesizing linear motion in two perpendicular directions. Door leaf motion has very good harmony and consistency.

Description

technical field [0001] The invention relates to the technical field of sliding doors, in particular to a sliding door which can be applied to rail vehicles and public vehicles, and which uses different power outputs for the sliding action and has no edge lock. Background technique [0002] Chinese patent "Sliding door", publication number: 110552592 A, discloses a sliding door including: a driving mechanism, a pulley link mechanism, and a locking and unlocking mechanism, wherein the driving mechanism is set in the middle position, and can move to the left and right sides The symmetrically arranged pulley link mechanism provides the driving force to complete the pull action, and drives the symmetrically arranged lock and unlock mechanisms on the left and right sides to complete the unlocking and locking actions when the door is opened or closed. The action input end of the pulley link mechanism and the drive The mechanism is connected, and the action output end is connected w...
