Structure preventing instrument board from collapsing down

The invention relates to a structure preventing an instrument board from collapsing down. The structure preventing the instrument board from collapsing down comprises an instrument board body, and a plurality of reinforcing structures are arranged below the front edge of the instrument board body. The structure is characterized in that each reinforcing structures is formed by supporting ribs and a connecting rib connected at the lower ends of the supporting ribs. The supporting ribs are four polygons which are identical in shape and structure and are arranged with equal distance in parallel, and the connecting rib is in a rectangular plate shape. The upper portions and the front portions of the supporting ribs are connected with the instrument board body, and the lower portions of the supporting ribs protrude outwards and are connected with the connecting rib. The supporting ribs, the connecting rib and the instrument board body are integrally formed in an injection molding mode. The structure preventing the
