The first and second side frames respectively include two load-bearing uprights 31 arranged oppositely, and the two ends of the third and fourth side frames are respectively connected to the first and second side frames. The movable frame 21 is arranged above the base frame 2 at intervals. The movable frame 21 includes a first riding frame 22 hinged to the first side frame 3, a second riding frame 23 hinged to the second side frame 4, and a bridge frame 24 arranged between the first riding frame 22 and the second riding frame 23. The first riding frame 22 can be folded and positioned on the first side frame 3, and the second riding frame 23 can be folded and positioned on the second side frame 4. The bridge frame 24 has an unfolded state connected to the first riding frame 22 and the second riding frame 23, and a stowed state separated from the second riding frame 23. In the unfolded state, a first storage layer 211 arranged between the bottom frame 2 and the movable frame 21 and a second storage layer 212 arranged on the upper side of the movable frame 21 are formed between the third and fourth side frames, so that the outdoor vehicle frame has a layered loading function, and the items can be classified and stored after shopping, which is convenient for classification and placement or taking.
