Device for operating opposite sliding doors

Abstract

A device for operating opposite sliding doors is included. The sliding doors are used in a vehicle having a vehicle body. The device comprising: a center rail mounted at a center inside a first door in a longitudinal direction of the vehicle body, the center rail formed in a curved shape so that the first door moves to the outside of a vehicle interior of the vehicle when the first door is opened;a center roller mounted on the vehicle body so as to correspond to the center rail, the center roller configured to move the center rail by being coupled to the center rail when the first door is opened or closed as a center bearing unit formed at one side of the center roller is seated on the center rail, wherein the center roller has a center shaft formed at a position spaced apart from the center bearing unit; a lower rail mounted at a lower side of the vehicle body in the longitudinal direction of the vehicle body, the lower rail formed in a curved shape so that the first door moves inside the vehicle when the first door is closed; and a lower roller mounted at a lower side inside the first door so as to correspond to the lower rail, the lower roller configured to move along the lowerrail by being coupled to the lower rail when the first door is opened or closed.

Description

technical field [0001] The invention relates to a device for operating opposed sliding doors. Background technique [0002] Generally, a vehicle has a passenger compartment having a predetermined size such that a driver or an accompanying passenger can sit therein, and a passenger compartment opening / closing door is installed on a vehicle body to open or close the passenger compartment. [0003] In the case of a passenger car, the passenger compartment opening / closing doors include a front door installed on the front side in the vehicle lengthwise direction, and a rear door installed on the rear side in the vehicle lengthwise direction. The front and rear doors are generally mounted on the vehicle body so as to be able to rotate on hinges. [0004] Meanwhile, in the case of a van that can seat multiple people, the passenger compartment opening / closing door slides back and forth in the longitudinal direction of the vehicle to open or close the passenger compartment.

AI Technical Summary

Problems solved by technology

[0007] However, in the prior art, there are problems in that the structure of the roller includes a plurality of links, so that the structure is complicated, minor failures often occur, and the product cost increases

[0008] Since the rear door device does not include a structure that prevents the door from rotating or moving when the door is opened or closed, there is a problem of deterioration in stability
