Electric turnover mechanism of row seat in movable auditorium

The utility model relates to an electric turnover mechanism of row seats in a movable auditorium. The utility model is characterized in that the electric turnover mechanism of row seats comprises a power control mechanism which is composed of a motor 4, speed change gears 5 and 6, a rotary shaft 10, the speed change gears 2 and 3, an output shaft 11 and a driving shift fork 1. A seat four bar linkage mechanism is composed of a back plate metal connecting piece 41, an aluminium alloy upright post 43, a seat plate metal connecting piece 44 and a handrail connecting piece 47, and a self-weight receiving and stacking principle is used. The back seat plate is turned over automatically by self weight after audience leave the seats, and the four bar linkage mechanism which is composed of a turnover supporting frame 21, a turnover mechanism frame 22, a long connecting bar 23 and a short connecting bar 24 is driven by the output shaft 11. Because the speed reducing motor (4) has the function of positive and reverse rotation, the swinging movement of the turnover supporting frame 21 is realized, and simultaneously the connected row seats with multiple seats are turned over. The electric turnover and the convenient transportation and installation of the row seats with multiple seats are realized.
