The invention discloses a connecting joint for an automobile tubular beam, which is used for connecting a co-driver side tubular beam and a main driver side tubular beam with different pipe diameters,the pipe diameter of the co-driver side tubular beam is smaller than that of the main driver side tubular beam, the connecting joint for the automobile tubular beam comprises a pipe body, the outer diameter of the pipe body matches the inner diameter of the main driver side tubular beam, and the inner diameter of the pipe body matches the outer diameter of the co-driver side tubular beam. The twoends of the connecting joint for the automobile tubular beam are arranged on the co-driver side tubular beam and the main driver side tubular beam in a welded and sleeving mode correspondingly, so that the co-driver side tubular beam and the main driver side tubular beam are connected, and the connecting strength is high; when the difference between the inner diameter and the outer diameter of the co-driver side tubular beam and the inner diameter and the outer diameter of the main driver side tubular beam is larger, the connecting joint for the automobile tubular beam is in a hollow shape, strength can be kept, and light weight can be achieved.

    本发明公开了一种汽车管梁用连接接头,用于连接管径不一致的副驾驶侧管梁和主驾驶侧管梁,其中,所述副驾驶侧管梁的管径小于所述主驾驶侧管梁的管径,所述汽车管梁用连接接头包括管体,所述管体的外径与所述主驾驶侧管梁的内径适配,其内径与所述副驾驶侧管梁的外径适配。本发明的汽车管梁用连接接头的两端分别焊接套设在副驾驶侧管梁和主驾驶侧管梁上,以将副驾驶侧管梁和主驾驶侧管梁连接起来,连接强度强;当副驾驶侧管梁和主驾驶侧管梁内外径差异交大时,汽车管梁用连接接头通过设置镂空形状,既能保留强度,也能实现轻量化。
