The sliding rail mechanism comprises an upper sliding rail (1), a lower sliding rail (2), a limiting piece (3), a guiding piece (4) and a sealing chain (5), the upper sliding rail (1) and the lower sliding rail (2) are in sliding fit, the limiting piece comprises limiting parts (3A) arranged side by side, the limiting parts are connected to the opening end wall (2A) of the lower sliding rail, and limiting grooves (3a) are oppositely formed in the limiting parts; the guide piece (4) is provided with a guide groove (4a), the middle of the guide piece is connected to the upper sliding rail, the two ends of the guide piece extend to the position between the two limiting parts, and upper limiting walls (3A1) of the limiting parts can be extruded to deform or restore after extrusion force is relieved. The sealing chain (5) can do snakelike motion, the middle of the sealing chain (5) is installed in the guide groove, the other parts are installed in the limiting groove in a limited mode, and the two ends of the sealing chain are connected with the lower sliding rail (2) in a limited mode. In the sealing structure, the sealing chain blocks the opening end of the lower sliding rail through the limiting piece, foreign matter is prevented from entering the sealing structure, and the sealing structure has certain supporting strength, can bear vertical force and achieves full-covering type sealing.

    本发明提供滑轨机构和车辆,包括滑动配合的上滑轨(1)和下滑轨(2),限位件(3),引导件(4)和密封链(5),限位件包括并列设置的限位部(3A),限位部连接于下滑轨的开口端壁(2A),并相对设置限位槽(3a);引导件(4)设引导槽(4a),引导件中部连接于上滑轨,两端延伸至两限位部间,限位部的上限位壁(3A1)能够挤压变形或在挤压力解除后恢复;密封链(5)能够做蛇形运动,中部安装在引导槽内部,其余部分限位安装在限位槽内部,密封链的两端部与下滑轨(2)限位连接。本发明的密封结构中,密封链通过限位件封堵下滑轨的开口端,防止异物进入,且具有一定支撑强度,可承受垂向力,实现全覆盖式密封。
