The doorsill supporting structure comprises a long-strip beam and a support assembly, the support assembly comprises at least one first support and at least one second support, the first support is fixed to one side of the long-strip beam and comprises an inner plate connecting part, and the second support is fixed to one side of the long-strip beam and comprises an outer plate connecting part; the inner plate connecting part is used for being connected with a doorsill inner plate; the second support is fixed to the other side of the long-strip beam, the second support comprises at least one outer plate connecting part, and the outer plate connecting part is used for being connected with a threshold outer plate; the first support and the second support are correspondingly arranged in the length direction of the long-strip beam. A stable force transmission structure is formed in the limited space between the threshold outer plate and the threshold inner plate through the second support, the long-strip beam and the first support, the effectiveness of load transmission in the side collision working condition is improved, meanwhile, the strength of the threshold assembly is improved, the deformation degree of a vehicle body due to side collision can be greatly reduced, and the service life of the vehicle body is prolonged. And the safety of the battery pack and passengers is improved.

    本发明公开了一种门槛支撑结构及门槛总成,包括长条梁与支架组件,所述支架组件包括至少一个第一支架与至少一个第二支架,所述第一支架固定于所述长条梁的一侧,所述第一支架包括内板连接部,所述内板连接部用于与门槛内板连接;所述第二支架固定于所述长条梁的另一侧,所述第二支架包括至少一个外板连接部,所述外板连接部用于与门槛外板连接;所述第一支架与所述第二支架在所述长条梁的长度方向上对应设置。本发明通过第二支架、长条梁与第一支架在门槛外板与门槛内板之间有限的空间内形成稳定的传力结构,提升侧碰工况中载荷传递的有效性,同时也提升门槛总成的强度,能够大大降低车身受到侧面碰撞的变形程度,提升电池包及乘员的安全性。
