The invention discloses an arrangement structure of reinforcing ribs for a back door trim panel. The arrangement structure comprises the back door trim panel, and longitudinal reinforcing ribs and transverse reinforcing ribs arranged vertically and horizontally on the back door trim panel in an intersecting manner. The arrangement structure is characterized in that the transverse reinforcing ribs are in a concave-convex form being higher on one segment and lower on the other, and the interval between every two adjacent concave segments is the distance between two continuous or three continuous longitudinal reinforcing ribs. By adopting the arrangement structure, deformation caused by the contraction difference between the reinforcing ribs and a main body in the cooling process of the back door trim panel can be reduced by reasonably optimizing the arrangement of the reinforcing ribs on the premise of not influencing the overall rigidity of parts, so that the effects of reducing the deformation of the back door trim panel and improving the trim quality are achieved.
