An A column comprises an A column upper connecting piece, an A column body and an A column lower connecting piece, and the A column upper connecting piece and the A column lower connecting piece are formed by aluminum or high-strength steel or ultrahigh-strength steel through hot air bulging; the A column body is formed by high-strength steel and ultrahigh-strength steel through hot gas bulging or aluminum extrusion; a first opening with a flanging structure is formed in the inner side of the A-column upper connecting piece, a fourth opening with a flanging structure is formed in the front side of the A-column upper connecting piece, a second opening with a flanging structure is formed in the inner side of the A-column lower connecting piece, a third opening with a flanging structure is formed in the rear side of the A-column lower connecting piece, and a U-shaped opening is formed in the top of the A-column upper connecting piece. The U-shaped opening is formed in a laser cutting process of the A-column upper connecting piece; and through the first, second, third and fourth openings and the U-shaped opening, mortise and tenon connection of the A column and the peripheral structure is realized. The invention further provides a tenon-and-mortise connection structure of the A column and the peripheral tubular beam and a vehicle.
一种A柱,其包括A柱上连接件、A柱本体和A柱下连接件,A柱上连接件和A柱下连接件分别由铝或高强钢或超高强钢通过热气胀成形;A柱本体由高强钢、超高强钢通过热气胀成形或铝挤压成形;A柱上连接件的内侧设置具有翻边结构的第一开口,A柱上连接件的前侧设置具有翻边结构的第四开口,A柱下连接件的内侧设置具有翻边结构的第二开口,A柱下连接件的后侧设置具有翻边结构的第三开口,A柱上连接件的顶部具有U型开口,U型开口形成于A柱上连接件的激光切割工艺中;通过前述第一、二、三、四开口和U型开口实现A柱和周边结构榫卯连接。本发明还提供了A柱与周边管梁的榫卯连接结构和车辆。
