The vehicle body tubular beam structure comprises an A column upper tubular beam and a die-casting B column connector which are of an integrated structure, the die-casting B column connector wraps the A column upper tubular beam in the die-casting B column connector through a semi-solid die-casting aluminum technology, the A column upper tubular beam is located in a side wall roof side rail cavity, and the A column upper tubular beam penetrates through the B column from the A column to the C column. The problem that the local strength of the joint position on the B column is weak can be effectively solved, and meanwhile the weight of a structural part is reduced.

    本发明公开了一种车身管梁结构和车辆,包括一体式结构的A柱上管梁和压铸B柱接头,所述压铸B柱接头通过半固态压铸铝工艺将所述A柱上管梁包裹在自身内部,所述A柱上管梁位于侧围上边梁腔体内部,所述A柱上管梁从A柱贯穿B柱、直到C柱。本发明可以有效解决B柱上接头位置局部强度薄弱的问题,同时减轻结构件的重量。
