The invention relates to a doorsill assembly, a vehicle body structure and a vehicle. The doorsill assembly comprises a doorsill inner plate, a doorsill outer plate and a reinforcing plate. The threshold inner plate and the threshold outer plate are connected and define an energy absorption cavity. The reinforcing plate is arranged in the energy absorption cavity, and the two opposite sides of the reinforcing plate are connected with the threshold inner plate and the threshold outer plate correspondingly. A connecting support is arranged at the bottom of the reinforcing plate and connected with the doorsill outer plate. The two opposite sides of the reinforcing plate are connected with the doorsill inner plate and the doorsill outer plate correspondingly, meanwhile, the bottom of the reinforcing plate is provided with a connecting support connected with the doorsill outer plate, at least three connecting and fixing points are arranged between the reinforcing plate and the doorsill outer plate and between the reinforcing plate and the doorsill inner plate, the position of the reinforcing plate in the energy absorption cavity is more reliable, the reinforcing plate is prevented from turning over, and the service life of the doorsill is prolonged. Therefore, collision energy can be transmitted to the reinforcing plate from the doorsill outer plate and then transmitted to the doorsill inner plate, so that the energy absorption effect of the doorsill assembly is improved, the collision intrusion amount is reduced, and the safety performance of the vehicle can be improved.
本公开涉及一种门槛总成、车身结构以及车辆,该门槛总成包括门槛内板、门槛外板以及加强板;门槛内板和门槛外板连接并围合形成吸能空腔;加强板设置在吸能空腔内,加强板的相对两侧分别与门槛内板和门槛外板连接;加强板的底部设置有连接支架,连接支架与门槛外板连接。加强板的相对两侧分别与门槛内板和门槛外板连接,同时加强板的底部设置与门槛外板连接的连接支架,使加强板与门槛外板以及门槛内板之间具有至少三处连接固定点,加强板在吸能空腔内的位置更为可靠,避免加强板发生翻转,碰撞能量可以由门槛外板传递至加强板后再传递至门槛内板,以此提升门槛总成的吸能效果,降低碰撞侵入量,进而可以提升车辆的安全性能。
