The invention relates to an automobile air conditioner air duct capable of inhibiting blow molding deformation, and belongs to the technical field of automobile air conditioner accessories. Comprising an air pipe body, and the cross section outline of the air pipe body is roughly of a square or rectangular hollow pipe body structure. The reinforcing convex ribs comprise grid convex ribs and strip-shaped convex ribs which are positioned on the outer wall surface of the air pipe body; the grid convex ribs are located on two opposite side walls of the air pipe body, and the strip-shaped convex ribs are located on the other two opposite side walls of the air pipe body; the multiple strip-shaped convex ribs are sequentially arranged at intervals in the length direction of the air pipe body, and the length direction of the strip-shaped convex ribs is the same as the demolding direction of the air pipe body. The grid convex ribs and the strip-shaped convex ribs are arranged on the outer wall face of the air pipe body. The grid convex ribs and the strip-shaped convex ribs can remarkably enhance the structural strength of the air pipe body, the side wall of the air pipe body is reinforced, product deformation is effectively controlled, and the collapse defect generated after blow molding of the air pipe body is restrained.
本申请涉及一种抑制吹塑变形的汽车空调风管,属于汽车空调配件技术领域。包括:风管本体,该风管本体的横截面轮廓大致呈正方形或长方形的空心管体结构;加强凸筋,该加强凸筋包括位于风管本体外壁面上的网格凸筋和条形凸筋;网格凸筋位于风管本体其中两个相对设置侧壁上,条形凸筋位于风管本体另外两个相对设置的侧壁上;条形凸筋设有多个且沿风管本体的长度方向依次间隔设置,条形凸筋的长度方向与风管本体的脱模方向相同。本申请在风管本体外壁面上设置了网格凸筋和条形凸筋。网格凸筋和条形凸筋能够显著增强风管本体的结构强度,风管本体的侧壁得到加强,有效控制了产品变形,抑制风管本体吹塑成型后产生塌陷缺陷。
