Novel electric stair-climbing vehicle

Abstract

The invention discloses a novel electric stair-climbing vehicle. The novel electric stair-climbing vehicle comprises pull handle, a pull handle height adjusting rod, push handles, tracks, a track adjusting frame, gear seats, a track shaft, fixing wheels, foot support sleeves, universal wheels, a foot support, front wheel supports, a seat adjusting support, a seat frame, a seat board, armrests, a backrest board and backrest rods. The pull handle is arranged at upper ends of the backrest rods, the fixing wheels are arranged at lower ends of the backrest rods, the seat frame is arranged at middle positions of the backrest rods, and one end of the seat frame is connected with the track adjusting frame. The pull handle height adjusting rod is arranged on the lower portion of the pull handle, the push handles are arranged on two sides of the pull handle height adjusting rod respectively, the armrests are arranged on the upper portion of the seat frame and on the backrest rods, and the backrest board is arranged on the backrest rods.
