The invention relates to the technical field of vehicles, in particular to a doorsill beam sealing structure and a vehicle. The doorsill beam sealing structure comprises a doorsill beam and an A column, the doorsill beam penetrates through the A column, the A column comprises an A column inner plate, an A column outer plate and a reinforcing part, the A column inner plate and the A column outer plate are at least in lap joint with the side portion and the top of the doorsill beam, a notch is formed in the lap joint position of the A column inner plate and/or the A column outer plate and the top of the doorsill beam, and the reinforcing part covers the notch. In the application, the doorsill beam penetrates through the column A, the column A is in lap joint with the side part and the top part of the doorsill beam, the fitting degree is high, the waterproof effect is good, and the fording capability of the vehicle is improved. In addition, the gap is formed in the lap joint position of the A column and the top of the doorsill beam, the sheet metal forming problem is solved, meanwhile, the reinforcer is arranged to reinforce the strength of the gap, stable connection of the overall structure is guaranteed, the rigidity of a vehicle body meets the requirement, and the wading sealing performance of the vehicle can be improved.

    本申请涉及车辆的技术领域,具体提出了一种门槛梁密封结构及车辆。门槛梁密封结构包括门槛梁和A柱,门槛梁贯穿A柱,A柱包括A柱内板、A柱外板和加强件,A柱内板和A柱外板至少与门槛梁的侧部和顶部搭接,A柱内板和/或A柱外板与门槛梁顶部相搭接的位置设有缺口,加强件覆盖缺口。在本申请中,门槛梁贯穿A柱,A柱与门槛梁的侧部和顶部搭接,贴合度高,防水效果好,提高车辆的涉水能力。此外,A柱与门槛梁顶部搭接的位置开设缺口,解决钣金成型问题,同时设置加强件补强缺口处的强度,保证整体结构连接稳固,使得车身刚度满足要求,还可以提升车辆涉水密封性能。
