This invention relates to the field of roof-mounted lift tent technology and discloses a bed board extension structure based on a roof-mounted lift tent. The structure includes a base, a canopy mounted on the base, a sliding support drive between the canopy and the base, a flip-up bed board mounted on the side of the base, and locking components and fixing linkages mounted on the canopy and base. The cross-support rod assembly of this invention, relying on the dynamic changes in structural form during the lifting process, achieves a dual improvement in support stability and load-bearing capacity, exhibiting significant force advantages. When not raised, the structure is easily compressible. As the canopy rises, the sliding end of the supporting rod gradually moves towards the center and becomes increasingly vertical, reducing the vertical angle and increasing the lateral angle. This allows the triangular support frame structure to form an efficient axial force characteristic, significantly weakening the bending moment effect and improving compression resistance. After reaching the highest position, the structure, combining its geometric shape and the central arrangement of the sliding end, forms a naturally stable structure that can effectively resist longitudinal pressure and lateral off-center loads.
