Footboard capable of being automatically and slowly folded

The invention discloses a footboard capable of being automatically and slowly folded. The footboard comprises a footboard seat, a main footboard, an auxiliary footboard, a footboard cover and a slow restoring mechanism. The footboard seat, the main footboard, the auxiliary footboard and the footboard cover are sequentially connected end to end in a pivoted mode, one end of the slow restoring mechanism is connected with the footboard seat in a pivoted mode, the other end of the slow restoring mechanism is connected with the auxiliary footboard in a pivoted mode, and the main footboard, the auxiliary footboard and the footboard cover can be unfolded or folded relative to the footboard seat. The footboard further comprises a limiting mechanism used for limiting the unfolding angle of the footboard seat, the main footboard, the auxiliary footboard and the footboard cover. By means of the footboard with the structure, a four-connecting-rod mechanism is formed by arranging the footboard seat, the main footboard, the auxiliary footboard and the footboard cover which are connected end to end in the pivoted mode, the restoring speed of the unfolded main footboard is controlled through the slow restoring mechanism, and the unfolding angle of the main footboard is limited by the limiting mechanism, so that the slow and automatic folding purpose is achieved, the folding and unfolding processes are smooth without noise, and high user-friendliness is achieved.
