The invention discloses an all-aluminum passenger car side wall stand column composite connecting structure which comprises a transversely-arranged top cross beam, a side beam and a vertically-arranged side wall stand column, the side wall stand column is perpendicular to the top cross beam and the side beam respectively, and at least one side face of the long edge of the top cross beam 1 is provided with a clamping groove 7. Clamping grooves 7 of the same structure are formed in the two side faces of the long edges of the edge beams 3 and the side wall stand columns 6, three edges of the U-shaped aluminum alloy casting are clamped into the clamping grooves of the top cross beams, the edge beams and the side wall stand columns correspondingly, through holes penetrating through the clamping grooves are formed in the surfaces of the top cross beams, the edge beams and the side wall stand columns correspondingly, and fixing bolts penetrate through the through holes to be fixed to the top cross beams. And the three edges of the U-shaped aluminum alloy casting are fixedly connected with the top cross beam, the edge beams and the side wall stand columns respectively. The side wall stand column is connected with the top cross beam and the side beams through the U-shaped aluminum alloy castings, natural transition of different elements is achieved, the structure effectively avoids vehicle body structure deformation caused by welding, and the connecting strength and precision of the side wall stand column are improved.

    本发明公开了一种全铝客车侧围立柱复合连接结构,包括有横向设置的顶横梁、边梁和竖向设置的侧围立柱,侧围立柱分别与顶横梁和边梁为相互垂直布置,顶横梁1的长边至少1个侧面设置有卡槽7,边梁3以及侧围立柱6的长边两个侧面均设结构相同的卡槽7,U型铝合金铸件的三条边分别卡入顶横梁、边梁以及侧围立柱的卡槽中,顶横梁、边梁以及侧围立柱的表面均设有穿过卡槽的通孔,固定螺栓穿过通孔后,将U型铝合金铸件的三条边分别与顶横梁、边梁以及侧围立柱固定连接在一起。该侧围立柱与顶横梁、边梁之间采用U型铝合金铸件进行连接,实现了不同元件的自然过渡,该结构有效避免焊接引起的车身结构变形,提高了侧围立柱的连接强度和精度。
