The embodiment of the utility model provides a threshold beam which is suitable for a vehicle and serves as a part of a lower vehicle body structure. The doorsill beam comprises a doorsill inner beam and a doorsill outer beam wrapping an outer beam of the doorsill inner beam. The threshold outer beam is provided with a stress section, an extrusion section and a guide section, the guide section is obliquely connected between the stress section and the extrusion section, and when external force is applied to the stress section, the guide section can guide the external force to be transmitted towards the extrusion section in the extending direction of the guide section. In the embodiment of the invention, the doorsill beam is arranged in the doorsill outer beam in a penetrating manner through the doorsill inner beam, so that the interior of the doorsill beam is additionally supported, the structural strength is improved, and meanwhile, external force acting on the outer side of the doorsill beam can be guided to
