Threshold beam assembly and vehicle

The invention discloses a threshold beam assembly and a vehicle. The doorsill beam assembly comprises a doorsill beam body and a transition support, the transition support is used for being connected between the doorsill beam body and a vehicle floor, and the melting point of the material of the transition support is larger than that of the material of the doorsill beam body so that the transition support can be connected with the vehicle floor in a welded mode. According to the doorsill beam assembly, the transition support is arranged and can be welded to the vehicle floor, so that the doorsill beam body can be connected to the vehicle floor, and the doorsill beam assembly can be connected to a vehicle body through an original vehicle body production line. 本发明公开了一种门槛梁总成及车辆。该门槛梁总成包括门槛梁本体和过渡支架，所述过渡支架用于连接在所述门槛梁本体和车辆地板之间，所述过渡支架的材质的熔点大于所述门槛梁本体的材质的熔点以与所述车辆地板焊接相连。本发明通过设置过渡支架，过渡支架可以与车辆地板焊接，从而可以将门槛梁本体连接于车辆地板，使得所述门槛梁总成可以采用原有的车身生产线连接至车身。
