The invention discloses a seat device used at the front end of a high-speed rail carriage, belongs to the technical field of high-speed rail carriages, and particularly relates to the seat device used at the front end of the high-speed rail carriage, the seat device comprises a seat back, a seat, a table plate and two supporting rods, the table plate is movably arranged on one side of the seat back, and the seat device further comprises two moving mechanisms; the two sets of moving mechanisms are installed on the two sides of the table board at intervals, and the moving mechanisms are used for moving the table board. Through rotation of the front seat back, a limiting block pushes a push rod to move backwards, a main gear is driven to rotate, a first bevel gear and a second bevel gear are driven to rotate, a worm and a worm gear are driven to rotate, and the gear rotates to drive a rack to move; the table plate moves relative to the movable block, the effect of keeping a certain distance between the table plate and the front seat back is achieved, in the moving process of the table plate, the inserting rod moves in the arc-shaped groove, the supporting plate rotates on the bottom face of the table plate to adjust the position, and the effect of continuously supporting the table plate through a plurality of supporting points is achieved.

    本发明公开了一种用于高铁车厢前端的座椅装置,属于高铁车厢技术领域,尤其是一种用于高铁车厢前端的座椅装置,包括椅背、椅座、桌板和两根支撑杆,所述桌板活动布置在椅背一侧,还包括两组移动机构,两组所述移动机构间隔安装在桌板的两侧,所述移动机构用于移动桌板,本发明通过前座椅背转动使得限位块向推动推杆向后移动,带动主齿轮转动、第一锥齿轮和第二锥齿轮转动,使得蜗杆转动和蜗轮转动,使得齿轮转动带动齿条移动,导致桌板相对活动块移动,达到保持桌板与前座椅背一定间距的效果,通过桌板移动过程中,插杆在弧型槽中活动,使得支撑板在桌板底面转动调整位置,达到持续通过多个支撑点支撑桌板的效果。
