Threshold beam of vehicle and vehicle

The invention discloses a doorsill beam of a vehicle and the vehicle, the doorsill beam comprises a first doorsill main body and a second doorsill main body, the first doorsill main body and the second doorsill main body are arranged and connected along the length direction of the doorsill beam, a containing space used for containing a vehicle door outer swing mechanism of the vehicle is formed in the first threshold body, a sliding space is formed in the second threshold body, the sliding space is used for assembling a sliding mechanism of the vehicle sliding door, and the first threshold body and the second threshold body are made of different materials. According to the threshold beam, by arranging the first threshold main body and the second threshold main body, the threshold beam can meet outward swing type door opening and sliding type door opening at the same time, the threshold beam can be matched with a B-pillar-free vehicle type, and the interior space of the vehicle can be increased. 本发明公开了一种车辆的门槛梁
